Description

Negative pressure drainage tube of leak protection gas

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a negative pressure drainage tube of leak protection gas.

Background

The negative pressure closed drainage can obviously accelerate the closure of an infected lacuna and the healing of an infected wound, greatly reduce the application of antibiotics, effectively reduce the occurrence of cross infection, shorten the treatment time, reduce the pain of a patient and be widely applied clinically.

When negative pressure closed drainage is used, a drainage tube is required to be inserted into a wound, then a biological semi-permeable membrane is used for attaching the wound to isolate the wound from the outside, and meanwhile, a pad pasting or a medical adhesive tape is used for attaching the drainage tube to the front part of the drainage tube. Because the negative pressure drainage can be led into an external negative pressure source through the drainage tube, the joint of the drainage tube and the human body is closed as much as possible, air leakage is prevented, the negative pressure environment is ensured, and the wound is prevented from being polluted. In the prior art, because the drainage tube is of a tubular structure, a gap is formed at the joint of the drainage tube and a human body, and air leakage is easy to occur, the method mainly comprises the steps of wrapping the drainage tube by a film or a medical adhesive tape as much as possible and then jointing the drainage tube and the human body, so as to reduce the size of the gap as much as possible, but the time of one-time negative pressure drainage is 7-10 days, the film or the medical adhesive tape can be loosened at the gap after long-time use, so that the gap is gradually enlarged, and air leakage is caused; in addition, the sticking film or the medical adhesive plaster is used as much as possible, and the drainage tube is pressed tightly to prevent air leakage, so that the use of materials is increased, the pain of a patient is increased, and particularly, the sticking film or the medical adhesive plaster is detached.

Meanwhile, because the negative pressure drainage time is long, the drainage tube is attached to a certain part of a human body for a long time to press the human body, the contact area between the drainage tube and the human body is small when the drainage tube is attached, the patient can be pressed and painful for a long time, through holes are formed in the patient, and particularly, the pain of the patient can be further aggravated under the condition that the drainage tube needs to be pressed for preventing air leakage. The existing mode is mainly characterized in that a piece of cotton cloth is padded between the joint of the drainage tube and a human body to relieve the compression, but corresponding problems are brought, firstly, the cotton cloth is not compact, air leakage is easily caused, and secondly, bacteria are easily bred in the cotton cloth to cause wound infection.
