Drainage removing device with negative pressure self-cleaning function

Abstract

The invention provides a drainage removing device with a negative pressure self-cleaning function, and relates to the field of medical treatment. The drainage removing device comprises a sinking bed, a negative pressure box, a circular rail traveling frame, a cleaning assembly and an operation manual unit; a position adjuster and an adjusting roller are arranged in the sinking bed; the negative pressure box moves through the position adjuster and the adjusting roller; The cleaning assembly carries out movable cleaning through the circular rail traveling frame; and the manual operation unit is used for carrying out manual cleaning operation in the negative pressure box. According to the invention, the negative pressure box is adopted, so that legs or feet of a patient are placed in the negative pressure box, and large-area negative pressure sealing winding does not exist around the surface of an affected part of the patient, so that smooth blood flow of the legs is guaranteed, and a good environment is provided for wound healing; large-area thick dressing is not arranged on the surface of a wound of the patient so as to benefit for flow-out of fester; the cleaning assembly and the manual operation unit are used for cleaning and nursing the surface of the wound, so that closing of the infected lacuna and healing of the infected wound surface can be remarkably accelerated.

Description

technical field [0001] The invention relates to a drainage clearing device with negative pressure self-cleaning. Background technique [0002] Vacuum Sealing Drainage VSD is applied to clinical repair of various acute and chronic wounds, and has a milestone significance for wound repair. After years of technological development, negative pressure drainage technology can be applied to wounds that are difficult to heal, such as diabetic foot ulcers, decubitus ulcers, and burns, for healing and repair. In the healing of skin drainage in leg surgery or foot surgery, although surgical drainage can be treated, inappropriate drainage has also brought many complications. Drainage cannot replace good surgery, but correct drainage, combined with surgery, will To make the operation more perfect, so far, drainage is one of the most basic problems in surgery, but there are very few people who can really study and solve this problem. [0003] Nowadays, in the application of common foot ...

AI Technical Summary

Problems solved by technology

[0004] 1. After wrapping the legs or feet tightly, although the airtightness will be improved, large-area wrapping will compress the blood vessels of the legs and feet, severely hinder blood flow, and affect wound healing. Complications such as ischemic numbness, unconsciousness, or severe necrosis of the lower limbs may occur if a large area is too tight;

[0005] 2. Dressings often get clogged. The common solution is to soak and moisten the dressing by injecting normal saline to improve the adsorption of the dressing. However, after the dressing is washed into the normal saline, its adsorption capacity has been occupied by the normal saline, and it absorbs pus. And the effect of edema fluid will be greatly reduced, and the adsorption capacity of the wound will become weaker;

[0006] 3. Medical personnel need to replace the dressing or a small amount of replacement, the workload of medical personnel increases, and the pain of the patient's wound will increase;

[0007] 4. One to two days after the drainage tube is drained, due to the high viscosity of abscess blood, dryness and blockage often occur in the drainage tube. The process of dredging the drainage tube is not to directly insert a rod to dredge it, destroying the negative pressure environment, or by slowly soaking in saline to improve the dryness of the tube, but this operation not only makes the patient uncomfortable and painful, but also requires a high degree of standardization of the actions of the operating medical staff, and often occurs It is difficult to clear the phenomenon of direct replacement of the overall dressing and pipeline, which is time-consuming and laborious, and is an extremely difficult technical problem in the application of surgical drainage technology
