Negative-pressure oxygen-carrying wound treatment device

Abstract

The invention provides a negative-pressure oxygen-carrying wound treatment device, and belongs to the field of medical apparatus. The wound treatment device disclosed by the invention is provided with a control module, as well as oxygen production equipment and an oxygen delivery pipe which are sequentially connected, and negative-pressure equipment, a negative-pressure tube, a liquid collection bottle and a drainage tube which are sequentially connected. An oxygen production control end is arranged on the control module for controlling the oxygen production equipment and a negative-pressure control end is arranged on the control module for controlling the negative-pressure equipment; and an oxygen bottle, which is provided with an oxygen concentration sensor, is arranged for regulating and controlling an oxygen concentration supplied to a wound and an air pressure sensor is arranged for regulating and controlling a negative-pressure vacuum degree supplied to the wound. The wound treatment device disclosed by the invention has a function of alternately supplying negative pressure and oxygen to the wound, so that a clinical working efficiency is improved and the disease recovery of a patient is promoted; and the wound treatment device has the characteristics of simple structure, good using effect and broad application scope to occasions.

Description

technical field [0001] The invention relates to the field of medical equipment, and belongs to a wound treatment device loaded with negative pressure oxygen. Background technique [0002] Wound negative pressure therapy technology is a new method to accelerate wound healing that has emerged in recent years. By placing professional medical dressings on the wound site and applying negative pressure (vacuum), it helps to pull the wound edge, remove local infection, and remove cells from cells. levels actively promote granulation tissue formation. Negative pressure wound therapy technology has been widely used in the treatment of a series of difficult-to-heal wounds, including acute, chronic, and infected wounds. It is also widely used to supply a certain concentration of oxygen to the wound surface to promote the recovery of cell granulation. In order to facilitate the rapid recovery of the wound surface, oxygen is often supplied to the wound surface after negative pressure t...

Problems solved by technology

However, there is a lack of operation suggestions, negative pressure and oxygen supply therapy devices that are easy to control and use in the market

Even if there is, its price is relatively expensive, and it is bound to use with the oxygen center or negative pressure center of the hospital, so it is not easy to carry

[0003] The patent with application number 201420152395.2 provides a device that combines negative pressure and oxygen supply. The oxygen supply is the oxygen center of the hospital. When used, it must be used in conjunction with the oxygen production center of the hospital, which is inconvenient to carry and use around.

And the concentration of oxygen supplied by the device is inaccurate, which has a certain impact on the recovery of wounds and wounds
