Negative pressure drainage device

Abstract

The invention provides a negative pressure drainage device, aiming at solving the problem that a traditional drainage device is easily blocked when in use and pus is easily deposited in a pressure cavity. The device comprises a vacuum pump, wherein the vacuum pump is connected with a cylinder body through a pressure pipe; the cylinder body has a split structure, and is connected with a drainage pipe; the drainage pipe is connected with a wound seal part for forming a sealed negative pressure environment at a wound, and a plurality of wound seal parts can be combined for use; and an anti-blocking device is arranged between the wound seal part and the drainage pipe; two opposite wheel bodies are arranged in the anti-blocking device, are provided with blades, and rotate oppositely under the action of a flexible shaft for stirring and crushing a passing-through fluid, so that mass tissues or caking can be crushed. The negative pressure drainage device is mainly used for draining a fluid in a wound, so that the pressure pipe is prevented from being blocked, and a fluid is prevented from entering the pressure pipe.

Description

technical field [0001] The invention relates to equipment for treating patients' mouth fluid, in particular to a negative pressure drainage device. Background technique [0002] The negative pressure drainage device is mainly used to treat wounds, especially some wounds that need to be regularly cleaned of pus. The vacuum pump is used to generate negative pressure in the drainage bottle, and the vacuum pump needs to be connected to the pressure chamber. The pressure chamber is connected to the drainage bottle to realize the negative pressure in the drainage bottle. However, there is not only pus in the patient's wound, but usually the diseased tissue of the patient. When using a negative pressure drainage device, the pus is easy to cause in the drainage tube when it enters the drainage bottle. Blockage will affect the drainage speed and even make it impossible to continue drainage. In addition, when the traditional drainage bottle is in use, the pressure chamber is connected...
