Anti-leakage device and method for intravenous transfusion for nursing in operating room

Abstract

The invention provides an intravenous infusion anti-leakage device used for operating room nursing. The device comprises a rectangular dressing (1), pressure and temperature sensors (2), a liquid control valve (3), a PLC (programmable logic controller) (4), an interactive display terminal (5) and a control switch, wherein the dressing (1) comprises a surface layer (11) and a bottom layer (12); the surface layer (11) is made from breathable transparent materials; the bottom layer (12) is made from breathable self-adhesive materials; a hole is reserved in the middle of the bottom layer (12) and serves as an observation window (7); a plurality of pressure and temperature sensors (2) connected with the PLC (4) are arranged around the hole in the bottom layer (12); the liquid control valve (3) is arranged at a liquid outlet of an intravenous infusion device (6); the PLC (4) is connected with the liquid control valve (3) and controls the liquid control valve to open and close; the interactive display terminal (5) is connected with the PLC (4); the control switch controls the device to open and close. An intravenous infusion anti-leakage method used for operating room nursing is used for judging whether liquid leakage happens by using the device. By adopting the device and the method, whether leakage happens to intravenous infusion can be accurately judged and the infusion device can be timely closed, thus reducing harms caused to patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-leakage device and method for intravenous infusion used in operating room care. Background technique [0002] Intravenous infusion is an important way to treat diseases. Fluid leakage may occur due to improper handling by medical staff or patient movement. Fluid leakage in intravenous infusion not only affects the quality of nursing work, but may even cause medical accidents. Especially chemotherapy drugs, once leakage occurs, it will cause subcutaneous tissue necrosis. In view of the above problems, a utility model with the notification number CN201058150Y discloses an intravenous infusion exposure alarm, in which a flexible oil bag is arranged inside the panel of the alarm housing, and a micro pressure sensor and a pressure alarm circuit are arranged between the oil bag and the alarm housing. Between the panels, when the infusion leakage occurs, the sensor senses the p...

AI Technical Summary

Problems solved by technology

However, the above-mentioned device has the following problems due to relying on pressure changes to realize the alarm: when the patient, especially the hand of a child moves, the oil bag will be deformed to change the pressure and cause a false alarm; False reporting, affecting the treatment effect of patients and even causing medical accidents

This type of anti-leakage device only judges the leakage situation based on the pressure of a single measuring point, and the accuracy is low
