Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a subcutaneous negative pressure drainage tube for patients with abdominal wound fat liquefaction. Background Art
[0002] Fat liquefaction of abdominal wounds is a common type of complication after cesarean section. Fat liquefaction during the healing process of the wound can easily cause incision infection and affect its healing. Prolonged wound healing not only causes pain to patients, but also increases the burden on medical staff. Obesity, diabetes, malnutrition, anemia, liver disease, improper operation during surgery, etc. can all induce fat liquefaction of incisions. The current treatments for fat liquefaction of abdominal wounds are: after fat liquefaction occurs in the wound, decide whether to reopen the wound for adequate drainage based on the amount of exudate in the wound site and the depth of the wound, and suture the wound a second time or use butterfly tape to heal after the exudate decreases; or microwave irradiation treatment; or negative pressure closed drainage, or external application of Chinese medicine to reduce exudation, or various dressings to reduce exudation. The above methods are all ways to reduce exudation and promote wound healing after the wound has liquefied. The above-mentioned treatment methods for fat liquefaction of abdominal wounds currently used in clinical practice are all for passive treatment when the patient's wound has already undergone liquefaction and exudation, or even the wound has cracked, causing physical and mental pain to the patient. In addition, the patient often needs to go to the hospital to treat the wound and change the dressing, which causes great inconvenience, takes a long time, and is costly. The wound needs to be sutured again after the wound exudation has decreased.
[0003] In view of the above technical problems, the utility model provides a subcutaneous negative pressure drainage tube for patients with fat liquefaction in abdominal wounds. The utility model is applied to high-risk patients with fat liquefaction in abdominal wounds after surgery. The drainage tube is placed when the wound is sutured after surgery, which can prevent the occurrence of fat liquefaction and promote wound healing. The patient can be discharged from the hospital with the tube after surgery, and the patient can operate it themselves at home, which is convenient and simple, highly practical, and reduces the pain of the patient and the burden on medical staff. The stitches on the wound are removed on time, and the tube is removed when there is not much exudate in the drainage tube, which does not affect wound healing. It is clinically recommended for application and can be implemented in medical institutions at all levels. It has good medical value and social value. Utility Model Content
