Description

Wound negative pressure suction tube Technical Field The utility model relates to the field of medical appliances, in particular to a wound negative pressure suction tube. Background The negative pressure drainage of wound exudate is to suck out the exudate in the wound by adopting the principle of negative pressure suction, and compared with the common drainage, the negative pressure drainage can drain out pus in the wound more rapidly and thoroughly, thereby being more beneficial to wound healing. The front part of the traditional wound negative pressure suction tube for wound negative pressure drainage is provided with a plurality of suction holes which are arranged at intervals along the length direction of the wound negative pressure suction tube, and the rear end of the traditional wound negative pressure suction tube is provided with a negative pressure joint. Negative pressure suction tube for wound the front part of the wound is placed into the wound, the rear end is connected with a negative pressure drainage bottle to realize negative pressure drainage of the wound. The wound negative pressure suction tube with the wound irrigation function is developed after further improvement on the basis of the existing wound negative pressure suction tube. This wound negative pressure suction tube adds an irrigation tube to the traditional wound negative pressure suction tube, which extends into and forward from the rear end of the suction tube to the front end. Flushing liquid such as normal saline can be injected into the wound through the flushing pipe, and the flushing liquid after flushing the wound is sucked out. The wound irrigation can effectively dilute pus to enable necrotic tissues to fall off, and can be smoothly discharged through negative pressure drainage, so that the wound is kept clean, bacterial sensitization is inhibited, a sterile environment is formed, and granulation growth and wound healing are facilitated. Such wound negative pressure aspiration tubes are disclosed in patent application 202122521682.9. In applicant's medical practice, it has been found that existing negative pressure wound suction tubes have some drawbacks. The negative pressure suction tube is made of medical plastic, the surface touch sense of the negative pressure suction tube is not good for muscles in a wound, and the negative pressure suction has the effect of sucking the muscles in the wound into the suction holes, so that discomfort or pain of a patient can be aggravated. Secondly, when the wound is washed, washing liquid flows out from the front end of the negative pressure suction tube of the wound and then returns to wash the wound, however, when the washing liquid returns, the washing liquid is sucked back into the suction tube after encountering the suction of the suction hole, so that the washing liquid does not flow far actually, and the wound washing effect is affected to a certain extent. Disclosure of utility model The utility model aims to solve the technical problem of providing a wound negative pressure suction tube which is beneficial to improving the comfort of wound negative pressure drainage. The negative pressure wound suction tube comprises a suction tube body and a flushing tube, wherein the front part of the suction tube body is a suction section, a plurality of groups of suction holes are formed in the suction section at intervals along the length direction of the suction section, the flushing tube penetrates into the suction tube body from the rear part of the suction tube body and extends forwards to penetrate out from the front end of the suction tube body, and the negative pressure wound suction tube further comprises a porous dressing sleeve, wherein the porous dressing sleeve is sleeved on the suction section.
