Bionic octopus negative pressure sucker for wound treatment

Abstract

The invention discloses a bionic octopus negative pressure sucker for wound treatment. The bionic octopus negative pressure sucker comprises a bionic primary sucker, a main negative pressure drainage catheter, bionic secondary suckers, secondary negative pressure drainage catheters and a negative pressure drainage connecting port, wherein the bionic primary sucker is connected with the bionic secondary suckers in a surrounding mode through the secondary negative pressure drainage catheters, the bionic primary sucker is connected with the main negative pressure drainage catheter, the main negative pressure drainage catheter is arranged to be of a multi-cavity catheter structure with a buffering function and a micro-spiral gas-liquid separation function, liquid and gas are separated and circulated, and the other end of the main negative pressure drainage catheter is used for being connected with an external negative pressure source. The number of the small suckers can be increased or decreased according to the area of a wound, and the small suckers are used for being flexibly applied to wound surfaces of various shapes or areas. According to the bionic octopus negative pressure sucker, the octopus bionic design is utilized, suction force is dispersed to the periphery, and therefore the wound is evenly covered with pressure, the structure is reasonable, and the defects that a traditional sucker is uneven in suction force, and wound seepage is prone to being accumulated and infection is caused are overcome.

Description

technical field [0001] The invention relates to the technical field of wound treatment facilities and the field of medical equipment, in particular to the new technology field of negative pressure wound treatment medical facilities, in particular to a bionic octopus negative pressure suction cup for wound treatment. It is an auxiliary consumable for vacuum sealing drainage (VSD) therapy technique. Background technique [0002] Vacuum Sealing Drainage (VSD) uses medical wound dressings containing drainage tubes to cover or fill skin and soft tissues. The defective wound is then sealed with a bio-semipermeable membrane to make it a closed space. Finally, the drainage tube is connected to a negative pressure source to drain excess blood and exudate from the wound through negative pressure, thereby promoting wound healing. [0003] The traditional method uses a perforated leather tube to be inserted into the sponge material, which is formed under the action of a negative pressu...

AI Technical Summary

Problems solved by technology

The traditional method has shortcomings such as low suction efficiency, low sponge utilization rate, and difficult connection and fixation.

Later, a negative pressure drainage suction cup used in wound negative pressure drainage therapy appeared. This suction cup can overcome the shortcomings of the traditional method of using a perforated leather tube inserted into the sponge for negative pressure drainage. The double-layer structure in the form of an inner opening channel is not easy to distort and deform. The filter layer is attached to the wound surface to form a negative pressure space. The filter layer is easy to block the drainage hole, resulting in poor drainage.

[0004] At present, suction cup drainage tubes are usually used clinically for negative pressure drainage, but the negative pressure suction cups in the prior art are mostly set with a single suction cup, and the suction position of the negative pressure suction cup is generally concentrated in the center of the wound, which is prone to negative pressure dead ends. It is easy to cause the suction cup to be blocked, which is not convenient for patients to nurse and treat, and the suction cup has poor adsorption effect, which may easily lead to the accumulation of wound exudate and increase the risk of infection
