Negative pressure suction cup for uniform drug delivery with buffer tank and quick release tube

Abstract

A negative-pressure suction cup provided with a buffer pool and a quick-release tube for even medicament application, comprising a suction cup body (1), a liquid feeding tube connector (2), a negative-pressure tube connector (3), and a quick-release tube (5). Provided within the suction cup body (1) are a buffer pool (13) used for buffering a cleansing solution or a medicinal solution and an outflow channel in communication with the buffer pool (13). The liquid feeding tube connector (2) is provided on the suction cup body (1) and in communication with the buffer pool (13). The negative-pressure tube connector (3) is provided on the suction cup body (1). The negative-pressure tube connector (3) is arranged at the center position of the suction cup body (1) and extended downward onto the lower surface of the suction cup body (1). The quick-release tube (5) is connected onto the liquid feeding tube connector (2) and the negative-pressure tube connector (3). By having the buffer pool provided on the suction cup body (1) for even medicament application, a diversion protrusion (18) provided for diversion, and the suction cup body (1) connected to the quick-release tube (5), the negative-pressure suction cup overcomes the shortcoming of existing wound cleaning and medicament application requiring repeated dressing and causing increased pain for a patient, uneven medicament application, and inconvenient detachment of the suction cup body (1) from an external tube.

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
