Portable negative pressure suction device for wound management for department of burn and plastic surgery

Abstract

The invention discloses a portable negative pressure suction device for wound management for department of burn and plastic surgery, which comprises a 3M medical patch, a negative pressure suction apparatus, a medicine storage bag and a collecting bottle. A first sponge for covering the surface of a wound is disposed on the lower end face of the 3M medical patch; a fluid discharge tube is disposed in the first sponge, and a plurality of fluid discharge holes are formed in the fluid discharge tube. The fluid discharge tube is led out of the 3M medical patch by means of a conduit and then connected to the medicine storage bag. A second sponge is disposed at the periphery of the first sponge, and a drainage tube is disposed in the second sponge. A plurality of drainage holes are formed in the drainage tube. The drainage tube is led out of the 3M medical patch by means of a conduit and then connected to a check valve, the outlet of the check valve is connected with the liquid inlet of the collecting bottle, and the air inlet of the negative pressure suction apparatus is connected with the liquid inlet of the collecting bottle by a conduit. The first sponge is thicker than the second sponge. Compared with the prior art, the portable negative pressure suction device for wound management for department of burn and plastic surgery is capable of promoting healing of the surface of a wound, and is small in size and convenient to carry, low in cost, and convenient to popularize and use.

Description

technical field [0001] The invention relates to the field of burn plastic surgery equipment, in particular to a portable negative pressure suction device for wound treatment in burn plastic surgery. Background technique [0002] VSD technology uses medical foam material as the intermediary between the drainage tube and the wound surface, seals the wound surface with a semi-permeable biological film, and connects a negative pressure suction device for continuous drainage. on the one hand. The use of negative pressure sealing and continuous suction can achieve all-round wound drainage, so that the exudate and necrotic tissue of the wound can be removed in time, reducing the reabsorption of toxic products by body tissues, and preventing the occurrence of multiple organ dysfunction syndrome (MODS). On the other hand, the semipermeable biofilm has the function of one-way ventilation, and the outside air and bacteria cannot enter the wound through this film. Turn the open wound ...

Problems solved by technology

However, the price of medical VSD ranges from 4000-8000 yuan, and each time it can only last for 5-7 days

Most patients still cannot fully accept the expensive price, and patients cannot stay away from the negative pressure in the center of the wall for 5-7 days in each course of treatment, which brings a lot of trouble and inconvenience to the life of patients and family members, and the noise is louder, Pressing and sucking out the exudate and necrotic tissue of the wound surface can not clean the wound surface with medicine, which is not conducive to wound healing
