A kind of special dressing dressing after limb amputation

Abstract

A special dressing for limb separation surgery, which is characterized in that it includes a sleeve with a closed end; a semi-permeable film is provided on the outside of the sleeve; an adsorption disc is provided outside the film at the closed end of the sleeve to absorb There is a through hole at the corresponding position between the disk and the film. The negative pressure suction tube on the adsorption disk passes through the through hole to continuously provide negative pressure suction for the sleeve; put the sleeve on the amputation stump, wrap the film on the sleeve, and pass through The negative pressure suction tube performs continuous negative pressure suction. The cylindrical composite nano-silver polyvinyl alcohol sponge tightens under the action of negative pressure, forming a uniform compression effect on the limb stump. The dressing can be exposed to the wound site, and the dressing has strong It has an effective and broad-spectrum anti-infection effect, and has a good promoting effect on wound healing. The wound exudate flows out through the drainage tube, keeping the wound clean.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a special dressing after limb amputation. Background technique [0002] Limb amputation is a common clinical operation, and postoperative dressing is a very important part. The existing postoperative bandaging is usually to place a drainage sheet at the surgical incision, and then pressurize it with gauze and bandage. But this kind wrapping method has the following disadvantages: [0003] 1) The pressure distribution is uneven. The traditional bandaging method exerts pressure along the radial direction of the limb, while there is almost no pressure in the cross-section of the amputated limb. [0004] 2) The pressure is difficult to control. The traditional bandaging method is difficult to precisely control the pressure. If the pressure is too small, it will not be possible to pressurize to stop bleeding, and if the pressure is too high, it will easily le...

Problems solved by technology

[0006] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a special dressing dressing after limb amputation, which solves the defect that the uneven pressure of the existing post-operative dressing can easily cause infection, and has a simple structure, It is safe and hygienic to apply force evenly on the wound and its surroundings
