An adjustable automatic negative pressure drainage device

Abstract

The invention discloses an adjustable automatic negative pressure drainage device, comprising: a drainage tank part, a sensor system and an adjustable automatic control device. The sensor system includes capacitive liquid level sensors I and II, which include capacitive liquid level sensors, sensor work indicator lights, three-hole plugs or socket, hook and loop; the adjustable automatic control device includes a battery pack, a fully automatic main control board, a negative pressure adjustment knob, an LED flashing indicator light, a micro vacuum pump, and an intermittent buzzer; the present invention has strong applicability , According to the actual situation of the patient, the negative pressure can be adjusted through the negative pressure adjustment knob, and the drainage device automatically drains the drainage. When the fluid drainage in the patient is clean, the control board controls the micro vacuum pump to stop working, the LED flashing indicator flashes, and the intermittent bee Buzzer alarm.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable automatic negative pressure drainage device. Background technique [0002] At present, the negative pressure drainage device used for surgical drainage often adopts a manual one-time preset negative pressure generator or an electric negative pressure generator. The negative pressure can be precisely regulated and continuously stable. Improper operation will cause the drained liquid to flow back to the drainage site. Although the electric negative pressure generator can generate continuous and stable negative pressure, the magnitude of the negative pressure cannot be adjusted, and it cannot realize automatic drainage and stop, which is time-consuming and labor-intensive, and inconvenient to use, which limits its wide application. SUMMARY OF THE INVENTION [0003] In view of the above existing technical problems, the present invention provides an adjustable...

Problems solved by technology

[0002] At present, the negative pressure drainage device used for surgical drainage often adopts a manual one-time preset negative pressure generator or an electric negative pressure generator. During the use of the manual one-time preset negative pressure generator, the negative pressure gradually decreases and cannot form Precisely adjustable and continuous stable negative pressure, improper operation may cause the drained fluid to flow back to the drainage site

Although the electric negative pressure generator can generate continuous and stable negative pressure, the size of the negative pressure cannot be adjusted, and it cannot realize automatic drainage and stop, which is time-consuming, laborious, and inconvenient to use, which limits its wide application
