Alternative hollow negative-pressure drainage treatment system for debridement circle hydrotherapy of wounds

Abstract

The invention discloses an alternative hollow negative-pressure drainage treatment system for debridement circle hydrotherapy of wounds according to a vacuum sealing drainage technology and a principle of promoting wound repair by virtue of hydrotherapy. The treatment system comprises a support cover, medical sponge, a water inlet passage, a water outlet passage, a drainage tube, and an input tube, and is characterized in that a tiny pipeline system is arranged in an inner core of the support cover, a side opening of a pipeline is positioned below the inner surface of the support cover, the medical sponge is arranged on the inner surface of the support cover, the water inlet passage and the water outlet passage are positioned at the top of the support cover, the lower end of the water inlet passage communicates with a tiny pipeline, the upper end of the water inlet passage is connected with the input tube, the lower end of the water outlet passage communicates with the support cover, and the upper end of the water outlet passage is connected with the drainage tube and is used for externally connecting an alternating negative-pressure suction device. The treatment system not only can clear wound secretion in time but also can continuously apply circle hydrotherapy and alternative hollow negative-pressure treatment to the wounds and keep low-oxygen humid environments of the wounds, thereby achieving an effect of promoting rapid healing of the wounds.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an alternate hollow negative pressure drainage treatment system for wound debridement circulation hydrotherapy. 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. Wounds that are difficult to heal are often treated with gauze wet compresses. This method requires freq...

Problems solved by technology

Although this technique has achieved great success in the treatment of various soft tissue defects and infections, it also has its own limitations

The treatment method is single, lack of treatment methods such as washing and debridement, drug delivery, oxygen therapy; insufficient drainage, especially for deep wounds or wounds with a lot of necrotic tissue, when the debridement of necrotic tissue is not handled properly, negative pressure drainage The negative pressure blind end caused by itself cannot completely drain the local exudate and necrotic tissue of the wound; the wound is in an isolated state, and the possibility of anaerobic infection is increased in the negative pressure formation area in the tissue; negative pressure sealing drainage makes The wound is always in a dry state, which is not conducive to wound healing
