Uniform dosing negative pressure sucker with buffer pool and quick release pipe

Abstract

The invention relates to medical equipment for draining and removing foreign matter such as wound fluid and necrotic tissues, and in particular to a uniform dosing negative pressure sucker with a buffer pool and a quick release pipe. The uniform dosing negative pressure sucker comprises a sucker body, a liquid feeding pipe joint, a negative pressure pipe joint and the quick release pipe; the buffer pool used for buffering cleanout fluid or medical solution and a flow-out channel communicated with the buffer pool are arranged in the sucker body; the liquid feeding pipe joint is arranged on the sucker body and is communicated with the buffer pool; the negative pressure pipe joint is arranged on the sucker body, is located in the mediate position of the sucker body and downwards extends to the lower surface of the sucker body; and the quick release pipe is connected to the liquid feeding pipe joint and the negative pressure pipe joint. According to the technical schemes that the buffer pool is arranged on a disc body of the sucker body for uniform dosing, flow guide protrusions are arranged on the disc body for flow dividing, and the sucker body is connected with the quick release pipe, the defects that during existing wound surface washing and dosing, repeated binding is needed, so that pains of a patient are increased, dosing is not uniform, and the sucker body and an external pipe are inconvenient to dismount are overcome.

Description

technical field [0001] The invention is a medical device for drainage and removal of wound exudate, necrotic tissue, foreign matter and other harmful substances, in particular to a negative pressure sucker for uniform drug delivery provided with a buffer pool and a quick-release tube. 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 spon...

[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 at the wound site leads to insufficient cleaning of some parts of the wound site, and the utilization rate of the cleaning solution is low. In addition, since the drainage tube has been implanted in the human body, it is inconvenient to disassemble
