Negative-pressure wound therapy device

Abstract

The invention discloses a negative-pressure wound therapy device, and relates to medical apparatus. The negative-pressure wound therapy device is provided with a sponge and two embedded main bodies, at least two drainage cavities are formed in the upper portion of each embedded main body, at least two rinsing cavities are formed below the drainage cavities in each embedded main body, drainage holes are formed in the upper sides of the drainage cavities, and rinsing holes are formed in the lower sides of the rinsing cavities; the embedded main bodies are embedded in the sponge, rinsing bases and drainage bases are arranged at the rear ends of the embedded main bodies, rinsing collection chambers communicating with the rinsing cavities are formed inside the rinsing bases, and drainage collection chambers communicating with the drainage cavities are formed inside the drainage bases; and the two drainage collection chambers are connected with a first channel end and a second channel end ofa T-shaped three-way ball valve through collection pipes respectively, the two rinsing collection chambers are connected with first channel ends of L-shaped three-way ball valves through rinsing pipes respectively, and a second channel end of each L-shaped three-way ball valve is connected with the collection pipe on the same embedded main body. The negative-pressure wound therapy device has theadvantages that the negative-pressure wound therapy device is simple in structure and convenient to use, during rinsing, the negative-pressure drainage pipes does not need to be closed, negative-pressure leaks cannot occur on wound surfaces, and thus the negative-pressure wound therapy device is safe and reliable and has good rinsing effects.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wound negative pressure treatment device with simple structure and convenient use, which does not need to close the negative pressure drainage tube during the flushing process, prevents negative pressure leakage from the wound surface, is safe and reliable, and has good flushing effect. Background technique [0002] We know that trauma negative pressure therapy technology was proposed by Wim Fleischman of ULM University in Germany in 1992, and it was successfully applied clinically and achieved good therapeutic effect. Professor Qiu Huade introduced this technology into China in 1994. After years of development, this technology has already It is widely used in general surgery, burn department, trauma department and other departments. A large number of literatures have confirmed that trauma negative pressure therapy technology can effectively promote wound healing and reduce the in...

AI Technical Summary

Problems solved by technology

[0004] Existing trauma negative pressure therapy devices have the following disadvantages: the irrigation tube penetrates into the drainage tube or the two are relatively close to each other. When washing and wetting through the irrigation tube, the drainage tube needs to be closed, otherwise the irrigation fluid cannot fully infiltrate the sponge If it is directly sucked away by the drainage tube, the effect of rinsing and wetting is poor, and if the drainage tube is closed for rinsing, there will be negative pressure in the sponge, and when the sealing effect of the drainage tube is poor or when there is a slight seal failure during use, the wound surface is prone to negative pressure Leakage increases the risk of wound infection and poor safety
