Problems solved by technology

As the exudate increases and dries up, sometimes it is easy to block the pores between the spongy bodies, resulting in unsmooth drainage of the spongy bodies
At present, there is no negative pressure drainage dressing device with flushing function clinically

Embodiment Construction

[0016] From figure 1 It can be seen that a flushable negative pressure drainage dressing includes a spongy body 1 , drainage catheter 6 , irrigation catheter 4 and the like. The sponge body 1 is made of composite polyvinyl alcohol porous material.

[0017] A double-lumen catheter 2 is inserted into the sponge body 1, and a plurality of through holes are evenly opened on the wall of the catheter tube inserted into the sponge body 1 by the double-lumen catheter 2 . The double-lumen catheter 2 is provided with a flushing cavity 21 and a drainage cavity 22. The wall of the flushing cavity 21 is provided with a number of flushing through holes, and the wall of the drainage cavity 22 is provided with a number of drainage holes. Such as figure 2 shown.

[0018] The outer end of the double-lumen catheter 2 is connected to the drainage catheter 6 and the flushing catheter 4 through a tee 3 . The other end of the flushing conduit 4 is connected with a joint 5 to facilitate connecti...

Abstract

The invention relates to washable negative pressure drainage dressing which comprises a sponge body, a drainage catheter and a washing catheter, wherein a double-cavity catheter is inserted in the sponge body, a plurality of through holes are evenly arranged on the wall of the double-cavity catheter inserted in the sponge body, and the outer end of the double-cavity catheter is connected with the drainage catheter and the washing catheter through a tee joint. A washing cavity channel and a drainage cavity channel are arranged in the double-cavity catheter. According to the washable negative pressure drainage dressing, the medical sponge body can be repeatedly washed in the treatment process, so that phenomena such as unsmooth drainage caused by drying and blocking of the sponge body in the wound negative pressure treating process are avoided. The washable negative pressure drainage dressing is reasonable in structure and convenient to operate and use, and reduces dressing change times and risk of clinical infection. In addition, the clinical operation is safe and convenient.

Description

technical field [0001] The invention relates to a medical consumable, in particular to a flushable negative-pressure drainage dressing applied to the closed-type negative-pressure drainage treatment of wounds. Background technique [0002] Wound closed negative pressure treatment technology is based on the traditional clinical negative pressure treatment method. The wound is placed with a medical sponge, and the wound is sealed with a biological transparent film to form a closed drainage system to prevent the invasion of external bacteria and improve the microcirculation of the wound. Increase the flow rate and dilate capillaries, thereby increasing the effect of rapid wound healing. Wound sealing negative pressure therapy technology is a new wound treatment technology developed in recent years, which can promote acute and chronic wound healing, including acute, chronic and infected wounds. Wound closed negative pressure therapy usually changes the medicine every 3 days or ...
