Vacuum oxygen supply device capable of maintaining wound to be in negative pressure state and supplying oxygen to wound

Abstract

The invention discloses a vacuum oxygen supplying device capable of maintaining a wound to be in a negative pressure state and supplying oxygen to the wound. The vacuum oxygen supplying device comprises a wound coating component, an oxygen delivery pipeline, a vacuum extraction fluid pipe, a first vacuum pump, a collection bottle and an oxygen machine, wherein the two ends of the oxygen delivery pipeline are respectively communicated with the wound coating component and fluid of the oxygen machine, the two ends of the vacuum extraction fluid pipe are respectively communicated with the wound coating component and the fluid of the collection bottle, and the first vacuum pump is arranged on the vacuum extraction fluid pipe between the wound coating component and the collection bottle. The vacuum oxygen supplying device disclosed by the invention can effectively prevent newly generated skin and flesh from being air-dried and chapped when the wound is too dry, enough oxygen and nutrient substance can be supplied to the wound, and the wound can be quickly healed.

Description

technical field [0001] The invention relates to a medical device, in particular to a vacuum oxygen supply device for keeping the wound in a negative pressure state and supplying oxygen to the wound. Background technique [0002] Chinese patent document CN101257876A discloses a self-contained wound dressing device, which applies vacuum pressure to the wound through an external peristaltic pump, so as to effectively suck away wound fluid or exudate from the wound base to promote wound healing; in order to apply continuous Constant vacuum, also using a pressure sensor to monitor the pressure in the wound dressing device and send a corresponding signal to the control device in order to cause the control device to activate the pump. However, the self-contained wound dressing device disclosed in the above-mentioned patent documents has the following technical defects in actual use: if the wound and its surroundings are kept at a relatively low relative vacuum, the fluid produced b...

AI Technical Summary

Problems solved by technology

However, the self-contained wound dressing device disclosed in the above-mentioned patent documents has the following technical defects in actual use: if the wound and its surroundings are kept at a relatively low relative vacuum, the fluid produced by the wound is very easy to be sucked away. It will make the periphery of the wound dry, and the new skin cells will lack the necessary water, so the new skin will be dry and chapped, which will slow down the wound healing speed; If the vacuum degree is high, the fluid produced by the wound is not easy to be sucked away in time, and the accumulated fluid will cause bacteria to grow, which will affect the wound healing; Nutrients can not effectively penetrate into the wound, which will affect the growth and development of new skin cells and delay the healing time of the wound
