Negative pressure suction cup for uniform drug delivery with split channel

Abstract

The invention relates to medical equipment capable of removing harmful materials such as wound surface fluid, necrotic tissues and foreign matters in a drainage mode, in particular to an even medicine feeding negative sucker provided with distribution channels. The negative sucker comprises a sucker body, a liquid sending pipe connector and a negative pressure pipe connector, the sucker body is internally provided with a containing cavity used for buffering cleanout fluid or liquid medicine and a plurality of the distribution channels which are communicated with the containing cavity, the distribution channels extend to the outer edge of the sucker body in a radial mode corresponding to the center of the sucker body, the liquid sending pipe connector is arranged on the sucker body and communicated with the containing cavity, and the negative pressure pipe connector is arranged on the sucker body, located at the center position of the sucker body and extends downwards to the lower surface of the sucker body. By means of the technical scheme that the containing cavity and the distribution channels are arranged on the sucker body, a buffer pool used for feeding medicine evenly is arranged on the sucker body, and drainage protrusions used for removing a wound surface in a drainage mode are formed in the sucker body, the defects that the pain of a patient is increased due to the fact that bandaging is needed to be conducted repeatedly during existing wound surface cleaning and medicine feeding, and medicine feeding is not even are overcome.

Description

technical field [0001] The invention relates to a medical device for drainage and removal of harmful substances such as wound exudate, necrotic tissue, and foreign matter, in particular to a negative-pressure sucker for uniform drug delivery provided with a shunt channel. Background technique [0002] During surgical operations, large-area skin wounds, soft tissue wounds, and wounds need to be cleaned and disinfected regularly. If harmful substances such as wound exudate, necrotic tissue, and foreign matter at the wound site cannot be removed in time, it will easily lead to suppuration or infection at the wound site. , the general method is to implant a spongy body and a drainage tube at the site of the surgical wound, compound an infusion tube on the same drainage tube, open holes on the side of the drainage tube to prevent blockage, and use the infusion tube to infuse the wound at a single point to achieve The purpose of cleaning and disinfection; use the sponge body to sp...

[0002] During surgical operations, large-area skin wounds, soft tissue wounds, and wounds need to be cleaned and disinfected regularly. If harmful substances such as wound exudate, necrotic tissue, and foreign matter at the wound site cannot be removed in time, it will easily lead to suppuration or infection at the wound site. , the general method is to implant a spongy body and a drainage tube at the site of the surgical wound, compound an infusion tube on the same drainage tube, open holes on the side of the drainage tube to prevent blockage, and use the infusion tube to infuse the wound at a single point to achieve The purpose of cleaning and disinfection; use the sponge body to spread the cleaning solution around the wound site; use the drainage tube to regularly discharge the accumulated blood and fluid in the wound site to avoid wound infection, but this method cannot be realized due to single-point infusion The uniform supply of medicine to the wound surface leads to insufficient cleaning of some parts of the wound surface, and the utilization rate of the cleaning solution is low
