Intelligent low constant pressure wound drainage system

Abstract

The invention discloses a smart low constant-pressure wound drainage system, which aims at providing a wound drainage system which can detect the actual negative pressure value and control a negative pressure pump to adjust the pressure during the drainage, so as to realize a scientific drainage treatment and reduce the labor intensity of the nursing staff. A pressure sensor is connected with a liquid tank; the pressure sensor is also connected with a control signal input terminal of a main drainage controller by an A / D converter; the control signal output terminal of the main drainage controller is connected with that of an AC voltage regulator by a D / A converter; the control signal output terminal of the AC voltage regulator is connected with a negative pressure pump which is connected with the liquid tank, and the main drainage controller is connected with a data inputting device. The smart low constant-pressure wound drainage system can detect the actual negative pressure value in the liquid tank and control the negative pressure pump to adjust the pressure during the drainage, thus realizing pressure monitoring and precise control; furthermore, the system has excellent performance of voltage regulation and simple operation and reduces the labor intensity of the nursing staff.

Description

technical field [0001] The invention relates to an intelligent low constant pressure wound drainage system. Background technique [0002] The low constant pressure wound drainage device is a device that cooperates with the drainage line to provide a constant low negative pressure suction source for drainage after medical operations. The device adopts a single-chip automatic control system to arbitrarily set the required low negative pressure value according to actual needs, realizes automatic adjustment, has high precision, avoids wound damage and infection, and accelerates wound healing. At present, there are mainly three kinds of devices used for wound drainage: disposable negative pressure drainage bottles (cans), wall negative pressure, and traditional negative pressure suction devices. These devices all have problems such as excessive negative pressure, poor adjustment accuracy, high labor intensity for nursing staff, and excessive noise, but the biggest problem is tha...

AI Technical Summary

Problems solved by technology

These devices all have problems such as excessive negative pressure, poor adjustment accuracy, high labor intensity for nursing staff, and excessive noise, but the biggest problem is that due to the gap between the system set value and the actual negative pressure value, the drainage system There is no actual measuring device for the negative pressure value in the system, therefore, it is difficult for the medical staff to truly understand the negative pressure value of the drainage system, and cannot provide objective data for reasonable drainage treatment, which affects the treatment effect
