Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a drainage tube fixing mechanism. Background Technology

[0002] Chest drainage involves placing one end of a drainage tube into the chest cavity and connecting the other end to a water-seal bottle positioned lower than the tube to expel gas or collect fluid from the chest cavity, allowing the lung tissue to reopen and restore its function. As a treatment method, it is used for drainage of hemothorax, pneumothorax, and empyema, as well as after thoracotomy, and plays a very important role in the treatment of these diseases. Currently, the common method for fixing chest drainage tubes in clinical practice is to use wound sutures and fix the drainage tube through the wound sutures, or to fix it directly with tape. Therefore, it has the following disadvantages: (1) The drainage tubes are often of uniform size, but the surgical wounds of patients are not uniform. (1) It is difficult to adjust the fit between the drainage tube and the wound. If it is too loose, it will easily slip off. If it is too tight, it will expand the wound and cause pain and discomfort, affecting healing. (2) For patients with long-term indwelling drainage tubes after surgery (thoracotomy for more than 7 days), the patient pulls the drainage tube when moving, causing wound pain or tearing of the wound. The wound needs to be treated a second time when the drainage tube is removed. (3) When the drainage tube is fixed with tape, it is often not fixed firmly and needs to be wrapped repeatedly. Every time the wound is changed, the tape must be removed and re-fixed, which is time-consuming and laborious. Secondly, it is easy to cause pain and inconvenience to patients who are allergic to tape, which increases the difficulty of medical staff.

[0003] In view of this, extensive and in-depth clinical research has been conducted to address the above-mentioned problems. For example, patent document CN202221454810.0 discloses "a novel chest drainage tube fixation device, including a first buckle cover, a second buckle cover movably mounted on the first buckle cover, connecting pieces respectively mounted on the front walls of the first and second buckle covers, a bolt screwed between the two connecting pieces, and openings respectively on the side walls of the first and second buckle covers, with a fixing tube mounted on each opening. This utility model relates to the field of drainage tube fixation technology. The drainage tube is fixed by inflating an airbag, which is secure. When changing the dressing of the wound, the second buckle cover can be opened by unscrewing the bolt. After the dressing is changed, the second buckle cover is fastened back to its original position, and the protective cover formed by the combination of the first and second buckle covers is fastened to the patient's wound by the fixing strap for protection."

[0004] Building upon this, this case eliminates unnecessary clasp structures for the skin wound and uses a balloon and surgical sutures to double-fix the drainage tube. Furthermore, the controllable ventilation balloon (similar to a urinary catheter inlet, which can be opened by pressing with a syringe to inject water and closed when the syringe is removed) can be adjusted for patients with different incision sizes and different wound healing processes, improving fit and comfort while reducing the workload of medical staff.
