Description

Disposable wound negative pressure suction tube

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to disposable wound vacuum aspiration tube.

Background

The mechanism of negative pressure drainage for treating the wound is that the wound surface is absorbed and exuded to help to establish the liquid balance of the wound surface; providing a humid environment; removing necrotic tissue; the number of bacteria on the wound surface is reduced, because the bacteria are not easy to survive under negative pressure; relieving edema, increasing wound surface blood flow, by increasing capillary engorgement; increasing a growth factor; promoting leukocytes and fibroblasts to enter the wound surface, wherein the leukocytes can resist infection and generate growth factors, and the fibroblasts can generate collagen for filling and repairing the wound; increasing venous filling and further accelerating the removal of edema liquid; lymphatic drainage from the wound surface is increased by changing the pressure of lymphatic vessels and the osmotic pressure of colloids; the tissues are close to each other, so that the tissues have an opportunity to naturally stick together by physical strength, and the healing is accelerated.

At present, when medical personnel carry out wound negative pressure drainage treatment on a patient, one end of a suction tube is usually connected with a negative pressure device, the other end of the suction tube is attached to a wound, and then the negative pressure device is started to carry out negative pressure suction, so that the suction is inconvenient, the size and the shape of the wound are different, the shape of the suction tube is fixed, the wound cannot be covered, and the suction force can only be concentrated on one part of the wound.
