Simple pumpback negative pressure device for wound repairing and healing and use method

Abstract

The invention discloses a simple pumpback negative pressure device for wound repairing and healing and a use method. The simple pumpback negative pressure device comprises a pasting dressing, a foam dressing, a medical hose, a negative pressure gauge, a gauge connector end and a negative pressure connector end, wherein the negative pressure connector end is a linked injector, a linked central negative pressure pipeline or a linked electronic negative pressure generator. An injector or a central negative pressure or electronic negative pressure extractor is linked with the negative pressure connector end, meanwhile, the negative pressure gauge is linked with a pressure testing gauge connector, negative pressure is pumped back till a pressure value of 80-120mmHg; when the pressure tends to be stable, whether air leakage phenomena are caused at different parts or not is checked, the pasting dressing and a wound are subjected to uniform negative pressure, a negative pressure environment can be formed between the wound and the pasting dressing, hyperaemia and edema of the wound can be effectively promoted to be relieved, wound healing can be greatly improved in a seepage mode of the pasting dressing, regrowth of granulation tissue of the wound can be improved, effective transferring of oxygen nutrition substances is improved and accelerated through blood flowing of the wound, and the risk of injection is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a simple retraction negative pressure device for wound repair and healing and a use method thereof. Background technique [0002] Studies have found that the concept of moist healing is beneficial to the repair and healing of wounds. Conventional common dressings such as gauze, gauze pads, etc. are not conducive to keeping the wound surface in a moist state, and need to be changed again. Common dressings will cause secondary damage to the wound surface when they are removed due to adhesion, which will bring pain to the patient. In order to satisfy moist healing, hydrocolloid dressings, foam dressings, alginate dressings, etc. are now mostly used. Although these dressings can keep the wound in a closed moist healing environment, there are still some problems as follows: [0003] 1. The above-mentioned dressings cannot provide a negative pressure environment after pasting,...

AI Technical Summary

Problems solved by technology

[0003] 1. The above-mentioned dressings cannot provide a negative pressure environment after pasting, and the adhesion to the wound surface is poor. Many times, alginate, debridement glue or some antibacterial dressings applied locally will fall off quickly, affecting the use and curative effect, and even Lead to the loss of antibacterial drugs contained in antibacterial dressings, greatly reducing the therapeutic effect or curative effect of antibacterial drugs

[0004] 2. Although bandages can be used to apply local pressure bandage to the wound, it is difficult to achieve local pressure bandage on some special parts such as jaw, temporal part, inner thigh, buttocks, sacrum and other parts, which will inevitably affect the activities of these special parts Effect

[0005] NPWT technology or VSD negative pressure technology has been used in wet healing therapy, but due to its expensive materials, it is generally only suitable for larger wounds. In addition, most wounds with larger wounds require hospitalization, and central negative pressure or electric therapy is needed. The negative pressure suction device is connected to the negative pressure suction pipeline, and the continuous negative pressure suction restricts the patient's activities and life, especially for outpatients who change dressings, causing a lot of inconvenience
