Abstract

The invention relates to the technical field of medical devices, in particular to a device for fixing a continuous negative pressure drainage device, which includes an elastic band, the end of the elastic band is provided with Velcro, the elastic band is provided with a sleeve, and a splint is provided for lateral sliding in the sleeve. One side of the splint is connected with a push rod, the free end of the push rod is hinged with a connecting rod, the free end of the connecting rod is provided with a slide rod, the side of the sleeve is provided with a bottom plate, the bottom plate is vertically provided with a limiting groove, and the limiting groove is provided with a Guide groove, the lower end of the guide groove is close to the sleeve, a slide plate is installed slidingly in the limit groove, the bottom of the slide plate is connected with a drive rod, and a strip hole is inclined on the slide plate, the inclination direction of the strip hole is opposite to the guide groove, and the slide bar slides Connects in bar holes and guide grooves. The invention solves the problems in the prior art that tapes need to be used to fix the empty needle again after the empty needle is removed, resulting in troublesome operation and increased treatment cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for fixing a continuous negative pressure drainage device. Background technique [0002] Empty needle negative pressure drainage is the most commonly used continuous negative pressure drainage method in clinical practice. It uses the principle of negative pressure suction to generate a pressure below atmospheric pressure on the wound surface and suck out the subcutaneous fluid of the wound surface. The application of disposable empty needle negative pressure drainage after plastic surgery can not only maintain effective drainage, but also facilitate the observation of the nature of the drainage fluid and accurate recording of the drainage volume, reducing the occurrence of complications such as skin flap necrosis and infection. [0003] Plastic surgery patients usually leave a disposable empty needle for continuous negative pressure drainage after brain or ear ca...
