SENSOR-BASED DETECTION OF REVERSE FLOW IN INTRA VENOUS GLUCOSE ADMINISTRATION FOR AUTOMATED PATIENT SAFETY

Abstract

The invention provides a sensor-based system for detecting reverse flow in intravenous glucose administration, enhancing patient safety by preventing complications such as clot formation, infection, or disruption of treatment. The system includes pressure and flow rate sensors that monitor the fluid dynamics within the IV line, coupled with a processor that analyzes data in real-time. Upon detecting reverse flow, the system can trigger an alarm or automatically stop the infusion. This automated approach reduces human error, ensures continuous monitoring, and integrates with existing hospital systems to improve patient outcomes.

Specification

Description:The system consists of an integrated network of sensors, data processors, and alert mechanisms designed to monitor the direction and flow rate of intravenous glucose infusions. The sensors used in the system include pressure transducers and flow rate sensors, which are strategically placed along the IV line to capture real-time data on the fluid dynamics within the system. These sensors detect any deviation from the normal, forward flow pattern that would indicate reverse flow or blockage.
Pressure sensors are particularly sensitive to subtle changes in the pressure gradient within the IV tubing. When reverse flow occurs, the pressure within the tube may fluctuate or even reverse, which can be detected by the pressure sensor. These sensors are calibrated to measure the precise levels of pressure that occur under normal, forward flow conditions, and any significant deviation from these readings can trigger an alert or shutdown the glucose administration.
Flow rate sensors monitor the volume of fluid passing through the IV line per unit of time. These sensors can detect variations in flow rate that might indicate an obstruction or reverse flow in the IV line. If the flow rate slows down unexpectedly or reverses, the sensor will transmit this information to the system's processor for analysis.
The processor uses algorithms to analyze the data from these sensors in real-time. The system is designed to recognize normal flow patterns as well as abnormal deviations such as reverse flow or blockage. Upon detection of a reverse flow event, the system can trigger an alarm to alert medical personnel or activate an automated response such as stopping the infusion or activating a corrective mechanism.
The invention also includes a user interface through which medical staff can monitor the status of the IV infusion system. This interface may be integrated with a hospital's existing monitoring system to provide comprehensive oversight of patient care. In addition, the system is designed to be compatible with various IV infusion pumps and glucose infusion systems, ensuring broad applicability in a variety of clinical settings.
To ensure continuous patient safety, the system is equipped with fail-safes and backup power systems, so it remains operational even in case of power failure or technical malfunction. The sensors used in the system are non-invasive and designed to work with minimal disruption to the normal functioning of the IV infusion setup.
In advanced embodiments, the system can be designed to communicate with other devices such as patient monitoring systems, infusion pumps, or electronic health records (EHR), allowing for seamless integration into the patient's overall care plan. This system can also be used to generate reports for medical professionals, assisting in data-driven decision-making.
The invention represents a significant advancement in automated patient safety, particularly in environments where glucose administration via IV is common. It reduces the risks of complications associated with reverse flow and enhances the ability of healthcare providers to respond quickly and effectively to potential issues. , Claims:1.A sensor-based system for detecting reverse flow in intravenous glucose administration, comprising pressure sensors, flow rate sensors, and a processor configured to monitor and analyze fluid flow conditions.
