Negative-pressure-drainage wound treating device

Abstract

The invention discloses a negative-pressure-drainage wound treating device. The negative-pressure-drainage wound treating device comprises a negative-pressure sponge, a sealing unit, a suction disc, adrainage tube, a washing tube and a plurality of drainage channels and is characterized in that the negative-pressure sponge is arranged above a wound, the sealing unit is arranged on the upper surface of the negative-pressure sponge and the suction disc, the suction disc comprises a bottom disc and an obtuse-angle connector connected with the drainage tube, the bottom of the bottom disc is provided with a through hole, the interior of the connector is communicated with the through hole, the connector penetrates the circular hole of the sealing unit, the washing tube is communicated with thelateral wall of the drainage tube, the drainage channels are fixedly peripherally arranged along the bottom of the bottom disc and communicated with the through hole, and each drainage channel is provided with a plurality of drainage holes; the negative-pressure sponge sequentially comprises a hemostasis layer, an adhesion-preventing layer, a support layer, a hemostasis layer and an adhesion-preventing layer from top to bottom. By negative-pressure-drainage wound treating device, effective hemostasis and antibacterial effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure drainage wound device. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in recent years for the treatment of wounds. It uses bio-semipermeable membranes to seal open wounds, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound through drainage tubes and dressings. Wound surface after debridement. Current research proves that this therapy can accelerate the blood circulation of the wound site, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, inhibit bacterial growth, and can directly accelerate wound healing, or for surgery. Repair conditions. It is an efficient, simple and economical pure physical therapy to promote wound healing. This t...

Problems solved by technology

[0003] In the traditional negative pressure drainage device, the drainage tube is parallel to the length direction of the sponge, and the drainage tube is led out from the side of the sponge, which is inconvenient to stick the film on. Moreover, under the negative pressure state, the sponge is compressed and deformed, which makes the drainage tube easy to be blocked and affects the Treatment effect, the existing hemostatic sponge has shortcomings such as poor hemostatic ability, or insufficient water absorption, which affects the healing of patients
