[0002] In clinical work, many patients are injured due to various burns, scalds, traffic accident injuries, bone injuries and other reasons, or their own physical causes: nasal cavity complications, anorectal complications, etc. Skin damage may exist, and the damaged wound surface often has a large amount of exudate and is accompanied by infection. In order to achieve timely drainage of wound exudate and create a good healing environment, the technology commonly used is closed negative pressure drainage technology. This technology combines negative pressure drainage catheter device with special wound covering film, and uses the support and adsorption of medical sponge to form and maintain a micro-negative pressure state with the skin wound. However, the current clinical products have some special needs for drainage of special wound surface sites. For example, during the drainage process, ventilation is required to achieve efficient drainage effect. There are many products that can meet the drainage requirements, but the adaptation to special wound surfaces is relatively single. Therefore, there is a special need for a new type of hemostatic drainage catheter.

[0003] However, most of the existing drainage catheters have many drainage catheter products that can meet the drainage requirements, but the adaptation to special wound surfaces is relatively single. For example, the utility model patent CN 205667564 U has a relatively single function for special pathological wound sites. The hemostatic effect is not satisfactory. After such surgery, there is a lot of effusion and a lot of excretion. If there is no timely drainage or the drainage efficiency is not high, it will cause wound infection, and in severe cases, it will damage the intestinal tract, causing many inconveniences and pain to the patient.
