Specification

Description:FIELD OF THE INVENTION:
The field of the present invention relates to anesthesia delivery systems, specifically focusing on an advanced anesthesia mask with integrated noise-reduction capabilities. This invention aims to improve patient comfort by minimizing environmental noise exposure during surgical procedures, contributing to a calmer and less stressful experience.

BACKGROUD OF THE INVENTION:
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Anesthesia masks have been an essential component in medical procedures, particularly during surgeries, where controlled administration of anesthetic gases is crucial for patient sedation and pain management. Over the years, anesthesia masks have evolved to accommodate various medical advancements, focusing primarily on safety, efficacy, and ease of use. However, one critical aspect often overlooked is the psychological comfort of the patient, particularly regarding noise levels in the operating environment. Operating rooms are often filled with various noises from machines, monitors, alarms, and the staff's communication, which, while essential for procedural efficiency and safety, can be unsettling for patients. Studies have shown that high noise levels can contribute to increased stress and anxiety, which may lead to elevated heart rates, higher blood pressure, and even slower recovery post-surgery. The presence of continuous and often unpredictable sounds in these clinical settings is, therefore, not only a source of discomfort but a factor that may inadvertently influence the outcome of the procedure and overall patient well-being.
For children, elderly patients, and individuals with heightened sensory sensitivities, the impact of operating room noise can be especially profound. Pediatric patients, for instance, are particularly susceptible to the fear of unknown noises, which can exacerbate preoperative anxiety. Elderly patients or those with cognitive impairments may also react negatively to sudden or unfamiliar sounds, which could lead to agitation or restlessness before sedation fully takes effect. Thus, a growing interest has emerged within the medical community to develop solutions that address these concerns, ensuring patients experience as little discomfort as possible, both physically and mentally.
One area of potential improvement involves anesthesia mask design. Traditional anesthesia masks are designed with the primary goal of delivering anesthetic agents effectively. They typically consist of a transparent, firm structure that seals around the nose and mouth, connected to an anesthesia machine. While recent designs have optimized the ergonomic fit and reduced air leaks, little attention has been given to the mask's potential to contribute to sound attenuation. Conventional anesthesia masks do not provide any barrier against ambient noise, allowing the surrounding sounds to permeate freely. Furthermore, existing designs often lack features that address active noise control, which could serve as an additional layer of comfort for patients in high-noise environments.
The concept of integrating noise-reduction technology into anesthesia masks introduces an innovative approach to improve patient comfort. This idea draws inspiration from noise-canceling headphones commonly used in consumer electronics, where similar principles could be applied in a medical context. The adoption of passive and active noise control techniques can create a quieter experience for patients under anesthesia, potentially mitigating preoperative anxiety and enhancing the overall sedation process. Passive noise reduction involves the use of sound-absorbing materials that naturally block certain frequencies, while active noise-canceling technology counteracts ambient sounds through opposing sound waves. Combining these elements in an anesthesia mask offers a promising pathway to reduce auditory disturbances in operating rooms.
In recent years, there has been significant progress in material sciences and miniaturization of electronic components, which now makes it feasible to incorporate noise-reducing elements into wearable medical devices without compromising functionality. For instance, lightweight, high-density foams and gel layers are increasingly used in various industries for soundproofing applications. Such materials can be adapted to anesthesia masks to block and dampen high-frequency noises commonly present in clinical environments. Additionally, advancements in microelectronics have enabled the development of compact noise-canceling circuits that can fit within small, flexible spaces, making it viable to embed active noise-canceling technology directly into the mask structure.
The integration of such a noise-reduction system into anesthesia masks could be particularly valuable for specific groups of patients. For example, in pediatric anesthesiology, where minimizing fear is essential for cooperation and successful sedation, a quieter environment could significantly reduce the need for additional sedatives or calming agents. Similarly, elderly patients or those with dementia, who may be more prone to disorientation or confusion, would benefit from reduced sensory overload, making the preoperative and intraoperative experience more manageable for both patients and medical staff.
From a procedural standpoint, an anesthesia mask with integrated noise-reduction features could also streamline the induction phase. With a calmer patient, anesthesiologists could focus more on the technical aspects of administering anesthesia rather than managing patient anxiety. Furthermore, a noise-reducing anesthesia mask could serve as an additional safety measure by allowing medical personnel to conduct necessary conversations without disturbing the patient, fostering a more focused and efficient operating room environment.
Despite the potential advantages, developing such a mask requires careful consideration of medical-grade standards and patient safety protocols. The materials used must be biocompatible, hypoallergenic, and durable enough to withstand sterilization processes. Additionally, the integration of electronic components for active noise cancellation must be designed to avoid interference with other sensitive medical equipment. Safety features such as automatic shutdown of electronic components during critical moments of the procedure would need to be incorporated to prevent any risk to the patient.
The challenge also extends to power requirements, as a sustainable power source would be necessary to maintain active noise cancellation throughout the surgery. Options such as compact, disposable batteries or rechargeable power cells could be explored, provided they do not add excessive bulk or complexity to the mask. With adequate research and engineering, these considerations can be addressed to create a mask that meets the stringent requirements of medical use.
Therefore, the development of a silent anesthesia mask with noise-reduction capabilities presents a promising advancement in patient care, particularly in surgical settings. By addressing the psychological aspects of noise-induced stress, this invention not only enhances the comfort of patients but may also contribute to a more favorable surgical outcome. As healthcare continues to evolve with an emphasis on holistic patient experience, innovations such as noise-reducing anesthesia masks will likely play an increasingly significant role in shaping modern medical practices. This invention could pave the way for further enhancements in anesthesia delivery systems, setting a new standard in patient-centered care in operating rooms worldwide.

OBJECTS OF THE INVENTION:
The prime object of the present invention is to provide an anesthesia mask with integrated noise-reduction capabilities, designed to minimize environmental sounds in the operating room. This feature aims to enhance patient comfort by significantly reducing noise-induced anxiety, particularly beneficial for patients with heightened sensory sensitivities, such as children, elderly individuals, or those with cognitive impairments.
Another object of the present invention is to incorporate both passive and active noise reduction technologies within the anesthesia mask. The passive noise reduction is achieved through sound-absorbing materials in the mask, while active noise-canceling technology further diminishes ambient sounds by generating counter-sound waves.

Yet another object of the invention is to enhance the focus and efficiency of medical staff in the operating room. By reducing patient anxiety through noise control, medical professionals can concentrate more on technical procedures, facilitating a smoother and more controlled anesthesia induction phase. This could potentially lower the need for additional calming agents or sedatives, promoting a safer anesthesia experience.
Still another object of the present invention is to develop an anesthesia mask that meets stringent medical standards for safety, biocompatibility, and durability. The materials used in the mask are intended to be hypoallergenic, suitable for sensitive skin, and capable of withstanding standard sterilization processes.

Another object of the invention is to explore sustainable power solutions for the noise-canceling functionality. The invention seeks to incorporate compact and lightweight power sources, such as disposable or rechargeable batteries, that provide sufficient energy for noise reduction throughout the duration of surgical procedures. This ensures the mask remains functional without adding excessive bulk or complexity, allowing patients to experience comfort without additional physical constraints.
Finally, an object of the present invention is to introduce a patient-centered innovation in anesthesia delivery systems that contributes to the overall well-being of patients and aligns with modern healthcare goals. By addressing not only the physical but also the psychological comfort of patients, the invention offers a holistic approach to anesthesia, setting a new standard in patient care during surgical procedures.

With reference to FIG. 1,
The silent anesthesia mask with noise-reduction system (100) is a specialized medical device designed to enhance patient comfort and reduce environmental noise in surgical settings. Its primary purpose is to provide a quieter experience for patients undergoing anesthesia, achieved by a combination of passive and active noise-reduction technologies integrated directly into the mask structure (10). This invention incorporates advanced sound-absorbing materials, noise-canceling technology, and ergonomic design elements to address the unique auditory challenges present in operating room environments.
The mask structure (10) includes a noise-reduction layer (20) embedded within its surface, designed to act as a passive barrier against ambient sounds. This layer (20) is formulated from sound-absorbing materials (22), including high-density foam and gel layers, which effectively dampen high-frequency noises commonly encountered in clinical environments. The high-density foam is carefully selected to absorb a wide range of frequencies, creating a first line of defense against disruptive sounds such as beeps, alarms, and the hum of machinery. Additionally, the gel layer within the noise-reduction layer (20) provides a secondary dampening effect by absorbing and dispersing sound waves. Together, these materials create a robust passive noise barrier that minimizes the auditory disturbance patients may experience, especially during the preoperative phase when anxiety levels are high.
Complementing the passive noise-reduction layer (20) is an active noise-canceling mechanism (30), which is seamlessly integrated into the mask to provide dynamic sound attenuation. The active noise-canceling mechanism (30) includes at least one microphone (32) positioned to capture surrounding sounds, particularly low-frequency noises such as those generated by ventilation systems, air filters, and other operational machinery in the operating room. These captured sounds are then processed by a noise-canceling circuit, which generates counteracting sound waves to neutralize the incoming noise. This active noise-canceling technology operates by analyzing the frequency and amplitude of the external sounds and producing an opposite waveform that effectively cancels out the noise before it reaches the patient's ears. This feature significantly enhances the auditory comfort of patients, making it particularly beneficial for those who are more sensitive to sound, such as pediatric and geriatric patients, or individuals with sensory sensitivities.
To support the active noise-canceling mechanism (30), the mask is equipped with a compact power source (40). This power source is designed to sustain the functionality of the noise-canceling components for the entire duration of a typical surgical procedure, which may last several hours. The power source (40) is typically a rechargeable battery embedded within the mask structure (10) in a manner that does not interfere with the mask's fit or comfort. The battery is both lightweight and durable, allowing the device to remain functional without adding excessive weight or bulk to the mask, thus ensuring the patient's comfort. This power configuration is particularly advantageous in surgical settings, as it provides a reliable and sustained power supply for continuous noise cancellation without the need for frequent recharging or replacement.
The mask's design also considers safety and medical standards, particularly regarding biocompatibility and interference with other equipment. The materials used in the mask structure (10), including the noise-reduction layer (20) and the components of the active noise-canceling mechanism (30), are hypoallergenic and biocompatible. This ensures that the mask is suitable for patients with sensitive skin, preventing allergic reactions or skin irritation during extended use. Additionally, these materials are chosen to withstand standard sterilization processes, including autoclaving and chemical disinfection, without compromising their structural integrity or the effectiveness of the noise-reduction layer (20). This durability is essential for ensuring the mask's reusability in clinical settings, making it both cost-effective and safe for repeated patient use.
To optimize fit and functionality, the mask includes an ergonomic seal around the patient's face, enhancing both anesthetic delivery and sound isolation. This seal is designed to create a snug fit around the nose and mouth, which not only prevents air leaks but also maximizes the effectiveness of the noise-reduction layer (20) by ensuring that external sounds do not enter the mask from the sides. This feature is particularly valuable in high-noise environments where even small gaps could compromise the noise-reduction capabilities of the mask. The ergonomic seal also enhances patient comfort by evenly distributing pressure around the face, reducing the risk of discomfort during prolonged procedures.
The active noise-canceling circuit within the mask is designed to adapt to the varying sound levels of the operating room environment. For example, during moments of increased noise, such as when certain medical equipment is in use, the noise-canceling mechanism (30) automatically adjusts its output to provide a higher level of noise reduction. Conversely, when ambient noise levels decrease, the mechanism reduces its output, conserving battery power while maintaining patient comfort. This adaptive functionality ensures that the mask consistently provides an optimal noise-canceling experience tailored to the operating room's dynamic sound environment, offering patients a calming auditory experience that supports sedation and minimizes stress.
The mask's noise-reduction layer (20) and active noise-canceling mechanism (30) work together to create a cumulative reduction in perceived noise. This dual-layer approach not only diminishes background sounds but also ensures that both high and low-frequency noises are effectively managed, offering a comprehensive noise-reduction solution. High-frequency noises are primarily absorbed by the passive noise-reduction layer (20), while low-frequency sounds are counteracted by the active noise-canceling mechanism (30). This synergy between passive and active noise control provides a quiet, stress-reducing environment for patients, particularly during the crucial moments before anesthesia takes full effect.
Another innovative aspect of the mask is the thoughtful placement and configuration of its noise-canceling components to avoid interference with other critical medical equipment in the operating room. Given the sensitivity of certain devices, especially those monitoring vital signs and providing life-support functions, it is essential that the mask's electronic components do not produce electromagnetic interference. To address this, the noise-canceling circuit and power source (40) are shielded and positioned to operate without impacting surrounding equipment, maintaining a safe and sterile surgical environment.
The materials used in the mask are specifically chosen not only for sound absorption and biocompatibility but also for their ability to maintain structural integrity after repeated sterilizations. The hypoallergenic nature of these materials ensures that they do not irritate the skin, even during extended use, and their durability allows them to withstand high-temperature and chemical sterilization processes. This feature ensures that the mask can be reused safely and cost-effectively across multiple procedures, aligning with hospital standards for sustainable and hygienic medical equipment.
Therefore, the silent anesthesia mask with noise-reduction system (100) represents a significant advancement in patient comfort and care during anesthesia. The combination of a noise-reduction layer (20) with sound-absorbing materials (22) and an active noise-canceling mechanism (30) with at least one microphone (32) and noise-canceling circuit provides a robust solution for managing environmental noise in surgical settings. The compact power source (40) ensures the active noise-canceling mechanism operates reliably throughout lengthy procedures, while the ergonomic fit and hypoallergenic materials contribute to the patient's comfort and safety. By offering adaptive noise reduction tailored to the dynamic sounds of the operating room, this mask provides a calming auditory environment that supports patient relaxation and minimizes preoperative anxiety. The innovative design, incorporating both passive and active noise-reduction technologies, sets a new standard for anesthesia delivery systems and aligns with the goals of modern patient-centered care in medical settings.

Working of the invention: The silent anesthesia mask with noise-reduction system (100) operates through a combination of passive and active noise-reduction mechanisms that work together to create a quiet environment for patients in the operating room. Here's a detailed breakdown of the mask's working process:
The core of the mask's functionality lies in the noise-reduction layer (20), embedded within the mask structure (10). This layer is composed of sound-absorbing materials (22), such as high-density foam and gel, which are specifically chosen to absorb high-frequency sounds, such as the beeping of monitors and machinery hums typical in surgical settings. When the mask is placed on the patient's face, this noise-reduction layer immediately begins to block out these high-frequency sounds. The materials used in this layer work by absorbing sound energy, preventing it from reaching the patient's ears, and thereby providing a basic level of auditory comfort as soon as the mask is donned.
In addition to the passive noise reduction, the mask is equipped with an active noise-canceling mechanism (30) designed to manage low-frequency sounds, which are not fully absorbed by the passive layer. This active noise-canceling mechanism includes at least one microphone (32) embedded within the mask, which picks up surrounding sounds, especially those that are more pervasive, such as ventilation systems or equipment vibrations. The microphone captures the frequency and amplitude of these ambient sounds and relays the data to an internal noise-canceling circuit.
The noise-canceling circuit processes the captured sound frequencies and generates counteracting sound waves that are the inverse of the incoming noise. These counteracting waves interfere with the external noise waves, effectively canceling them out. This phenomenon, known as destructive interference, is achieved by producing sound waves that have the same amplitude but opposite phase as the incoming sounds. By neutralizing these low-frequency sounds, the active noise-canceling mechanism provides a significant reduction in perceived noise levels, allowing patients to experience a quieter environment while wearing the mask.
To ensure that the active noise-canceling mechanism (30) functions effectively throughout the duration of the procedure, the mask includes a compact power source (40), typically a rechargeable battery, which is embedded within the mask structure (10). This battery is designed to provide consistent power to the noise-canceling circuit and microphone for extended periods, accommodating even lengthy surgical procedures. The power source is configured to be lightweight and unobtrusive, ensuring that it does not add bulk to the mask or compromise the patient's comfort. The battery is also positioned strategically to avoid creating electromagnetic interference with other medical devices, maintaining a safe environment in the operating room.
One of the key features of this invention is its adaptability to the dynamic sound environment of an operating room. The noise-canceling circuit is configured to adjust its output based on varying ambient noise levels. For instance, if machinery or equipment usage increases noise levels temporarily, the circuit automatically responds by generating a stronger noise-canceling output. When ambient noise decreases, the circuit reduces its output accordingly, conserving battery life and maintaining a consistent level of noise reduction without overwhelming the patient with excessive counter-sound. This adaptive capability ensures that the mask provides optimal noise control tailored to the changing sounds in the operating room environment, enhancing the patient's comfort throughout the procedure.
The ergonomic design of the mask, including a form-fitting seal around the nose and mouth, supports both anesthetic delivery and sound isolation. This seal not only ensures an effective and comfortable fit for the patient but also prevents air leaks that could otherwise diminish the efficacy of both anesthetic administration and noise reduction. By creating a tight seal, the mask prevents external noise from bypassing the noise-reduction layer and reaching the patient's ears directly, thereby enhancing the overall effectiveness of both passive and active noise control.
Furthermore, the materials used in the mask are hypoallergenic and biocompatible, designed to be safe for sensitive skin. These materials are capable of withstanding standard sterilization methods, such as autoclaving or chemical disinfection, without losing their sound-dampening qualities or structural integrity. This durability ensures that the mask can be reused safely and cost-effectively in a clinical setting, aligning with hospital standards for sustainable and hygienic medical equipment.
The combination of passive noise reduction through the noise-reduction layer (20) and active noise cancellation via the noise-canceling mechanism (30) results in a cumulative reduction of perceived noise for the patient. The high-frequency sounds are primarily absorbed by the passive noise-reduction layer, while the low-frequency sounds are managed by the active noise-canceling technology. This dual-layer approach provides a comprehensive solution to noise reduction, creating a tranquil auditory environment that reduces patient stress and anxiety. By addressing both types of ambient sounds, the mask ensures that patients experience a quieter and less distressing preoperative period.
Overall, the silent anesthesia mask with noise-reduction system (100) operates by actively and passively reducing ambient noise in surgical settings, providing an enhanced patient experience. This innovation contributes to modern patient-centered care by addressing not only the physical but also the psychological comfort of patients during anesthesia administration. Through advanced noise-reduction technology, the mask promotes a calm and quiet environment that supports relaxation and minimizes preoperative stress, ultimately contributing to improved patient outcomes.

Still another advantage of the invention is its hypoallergenic and biocompatible materials, which make the mask safe for sensitive skin and suitable for repeated sterilization, aligning with hygiene standards in clinical environments.
An additional advantage of the invention is the adaptive noise-canceling circuit, which adjusts noise cancellation output based on changing sound levels in the operating room, ensuring optimal comfort without draining the power source.
A further advantage of the invention is its compact, rechargeable power source, providing sustained noise cancellation throughout lengthy procedures without adding bulk, thus maintaining patient comfort and device functionality.
Another advantage is that the mask's design minimizes interference with other operating room equipment, making it compatible with medical devices essential for monitoring and ensuring patient safety during anesthesia.
