Skin wound treating system used for debridement and drug administration and oxygen supply

Abstract

The invention relates to a skin wound treating system used for debridement and drug administration and oxygen supply. The skin wound treating system comprises an adsorbent, a liquid collection device, a drainage pipeline, an infusion bag, a flushing pipeline, an oxygen supply device and an oxygen delivery pipeline, the adsorbent is used for covering a wound, the liquid collection device is used for generating negative pressure and collecting liquid, the drainage pipeline connects the adsorbent with the liquid collection device, the flushing pipeline connects the adsorbent with the infusion bag, the infusion bag is higher than the adsorbent in the vertical direction, the oxygen supply device is used for generating oxygen, the oxygen delivery pipeline connects the adsorbent with the oxygen supply device, and the drainage pipeline, the flushing pipeline and the oxygen delivery pipeline are arranged separately. The skin wound treating system realizes combining of traditional Chinese medicine (compound Huangbai liquid) flushing treatment and physical treatment, plays a role in protecting the surface of the wound, preventing infection and promoting healing of the surface of the wound, and is convenient to use, number of dressing times is reduced, treatment time is shortened, and pain of patients and burden of medical staff are reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a skin wound treatment system for wound debridement and oxygen supply. Background technique [0002] For the treatment and treatment of acute and chronic wounds, in the early days, bandages were mostly used for primary care, and the form was single. Now, the clinical treatment of wounds mostly uses physiological saline washing, sterilization treatment, dressing coverage, wound negative pressure sealing and other methods. Failure to take care of various factors related to wound healing in the process of wound healing affects the healing of the wound, resulting in easy contamination of bacteria during the transportation process, and repeated cleaning and removal of impurities may be required, which may cause the wound to expand; for infection Gauze wet compresses are often used to treat wounds that are difficult to heal. This method requires frequent dressing changes, tears and pai...

AI Technical Summary

Problems solved by technology

[0005] 1. The treatment method is single, and there is a lack of treatment methods such as irrigation and debridement, drug delivery, and oxygen therapy

[0006] 2. Insufficient drainage, especially for deep wounds or wounds with a lot of necrotic tissue, when the necrotic tissue debridement is not handled properly, the negative pressure blind end caused by negative pressure drainage itself cannot make the local exudate of the wound complete drainage of necrotic tissue

[0008] 4. The clinical efficacy of rational use of negative pressure therapy is positive, but the optimal treatment parameters for different patients and specific wounds have yet to be determined

[0009] 5. There are potential risks: the US FDA’s safety report on November 16, 2009 announced the death of 6 patients caused by negative pressure therapy

The main reason is that the rupture of the blood vessels during the negative pressure treatment caused rapid and massive bleeding that was not detected in time, resulting in the patient's hemorrhagic shock and eventually death

[0010] 6. Lack of effective drugs with comprehensive therapeutic mechanisms

[0011] Chronic difficult-to-heal wounds are due to local tissue ischemia and neuropathy in patients. With the development of the disease, ulcers, infections, and necrosis will occur in sequence, especially the ischemic changes in peripheral arteries such as the calf, which will lead to oxygenation of ulcer wounds, nutrient supply obstacles, and infection. Low tissue immunity and uncontrollable infection lead to tissue necrosis, which eventually leads to amputation. The pathogenesis is complicated and the treatment is difficult
