Embodiment 1

[0018] Embodiment 1: a negative pressure drainage device, comprising a vacuum pump 1, the vacuum pump 1 is connected to a bottle body 200 forming a cavity through a pressure tube 2, and one end of the pressure tube 2 communicates with the cavity to form a vacuum pump 1 that can pump air into the cavity to form a negative pressure. Pressure structure, one end of the pressure tube 2 is connected to the pressure port 3, and the pressure port 3 is in a sealed connection with the pressure chamber. The bottle body 200 is a dumbbell-shaped structure with large ends and a small center. Preferably, the bottle body 200 is a split structure, and its connection is located in the small middle part of the bottle body 200. The bottle body 200 includes a drainage part 201 placed vertically at the lower end. , the drainage part 201 extends upward and shrinks to form the first connecting part 202 with a diameter smaller than that of the lower part, and also includes a pressure chamber part 203 a...

Abstract

The invention provides a negative pressure drainage device, which solves the problem that the traditional drainage device is prone to blockage during use, and pus is easy to accumulate in the pressure chamber. It includes a vacuum pump, which is connected to a bottle body through a pressure tube. The bottle body is Split structure, the bottle body is also connected with a drainage tube, and the drainage tube is also connected with a wound sealing part that forms a sealed negative pressure environment with the wound. Multiple wound sealing parts can be used together. In addition, between the wound sealing part and the drainage tube There is an anti-blocking device in between, and the anti-blocking device is provided with two opposite wheel bodies, and the wheel bodies are equipped with blades, and the wheel bodies form relative rotation under the action of the flexible shaft, and the liquid is stirred and broken, so that the large pieces The tissue or agglomerate is broken, and the present invention is mainly used for draining fluid in the wound, which can prevent blockage and fluid from entering the pressure tube.

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...
