Negative pressure drainage device capable of monitoring and regulating pressure in bottle

Abstract

The invention relates to a negative pressure drainage device capable of monitoring and regulating pressure in a bottle. The negative pressure drainage device comprises a negative pressure drainage device body and a negative pressure control device, wherein the negative pressure drainage device body comprises a rigid bottle body with an inner cavity, a drainage pipe communicating with the inner cavity of the bottle body, and a vacuumizing motor; the vacuumizing motor is used for vacuumizing the inner cavity of the bottle body to form the negative pressure; and the negative pressure control device comprises a micro-control unit, a power supply module, a sensor module, a motor control module, an indicator light module and a tap position control switch module. The negative pressure drainage device is high in adaptation, and can more favorably meet the drainage requirements of the negative pressure of different pressure values; a check value is installed in a drainage tube or on the outletof the drainage tube to prevent liquid in the bottle body from overflowing or flowing backwards after the bottle body is full of the liquid; and through an anti-reverse-flowing device, a situation that the liquid in the bottle body flows into a motor to burn down a circuit when the bottle body inclines can be avoided. The negative pressure drainage device has the advantages of being simple in structure, convenient in operation, low in economic cost and easy in large-scale promotion and application.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates to a negative pressure drainage device capable of monitoring and adjusting the pressure in a bottle, which can realize multi-level pressure adjustment and automatically control the start or stop of a motor by monitoring the pressure value in the bottle. Background technique [0002] At present, in the clinical field of medicine, negative pressure drainage of postoperative wounds has been widely promoted and applied, mainly used in thyroid surgery, mammary gland surgery, trauma surgery, etc. The body parts of these operations are traumatized and the wounds ooze blood and exudate. Negative pressure drainage realizes effective wound care, which is of great practical significance for wound healing and prevention of complications such as skin flap necrosis, wound infection, and tumor recurrence.

Problems solved by technology

However, since the negative pressure of medical devices is usually divided into low pressure, medium pressure, and high pressure, there is only one mode of negative pressure operation, which is very inconvenient and poor in adaptability in clinical use; The problem of unprotected circuits in the liquid state still exists, which poses a safety hazard to patients
