Adjustable type full-automatic negative pressure drainage apparatus

Abstract

The invention discloses an adjustable type full-automatic negative pressure drainage apparatus. The negative pressure drainage apparatus comprises a drainage tank part, a sensor system and an adjustable type full-automatic control device, wherein the drainage tank part comprises a step reducing type drainage joint, a pipeline, a sheet-type interceptor, an air one-way valve, a U-shaped communicating vessel and a tank body; the sensor system comprises capacitive liquid level sensors I and II, the capacitive liquid level sensors I comprises a capacitive liquid level sensor body, a sensor work indicator lamp, a three-jack plug and Velcro, and the capacitive liquid level sensors II comprises a capacitive liquid level sensor body, a sensor work indicator lamp, a three-jack socket and Velcro; andthe adjustable type full-automatic control device comprises a battery pack, a full-automatic master control board, a negative pressure quantity adjusting knob, an LED flashing indicator lamp, a minivacuum pump and an intermittent buzzer. The adjustable type full-automatic negative pressure drainage apparatus is high in applicability, the negative pressure can be adjusted by the negative pressurequantity adjusting knob according to the actual condition of a patient, the drainage apparatus performs drainage automatically, when hydrops in the patient body is drained thoroughly, the control board controls the mini vacuum pump to stop working, the LED flashing indicator lamp flashes, and the intermittent buzzer gives an alarm.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable fully 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. During the use of the manual one-time preset negative pressure generator, the negative pressure gradually decreases and cannot form The negative pressure can be precisely regulated and continuously stabilized. 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.
