Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a flexible and shape-adjustable chest drainage catheter. Background Technology

[0002] The purpose of a chest drainage tube is to remove fluid, air, or blood from the pleural cavity, helping to restore normal pressure and respiratory function within the pleural cavity. Through a chest drainage tube, fluid or air can be drained from the pleural cavity, reducing the impact of pressure on the lungs, improving respiratory function, and preventing complications.

[0003] Current chest drainage tubes are generally made of silicone. Silicone provides some support, helping to stretch the intercostal muscles and prevent the tube from kinking and causing drainage obstruction. However, its rigidity can easily puncture the lung and chest wall, causing postoperative pain for the patient. (See reference...) Figure 3 Therefore, we propose a flexible and shape-adjustable chest drainage catheter to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a flexible and shape-adjustable thoracic drainage catheter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flexible and shape-adjustable chest drainage tube includes a drainage tube with medical adhesive tape attached to it. The drainage tube is fixed to the skin of the patient's chest wall by the medical adhesive tape. An opening is made between two ribs inside the patient's chest wall. One end of the drainage tube is inserted into the chest cavity through the opening. A fixing rope is provided on the outer surface of the drainage tube to fix the drainage tube to the opening of the patient's chest wall. The characteristic feature is that multiple shaping strips are provided inside the drainage tube, and multiple side holes are opened on the side of the end of the drainage tube that connects to the chest bottle.

[0007] Preferably, there are six to eight shaping strips, and the side holes are located between two shaping strips.

[0008] Preferably, the shaping strip is made of aluminum wire or other malleable metal wire.

[0009] Preferably, one end of the drainage catheter inserted into the pleural cavity is shaped to fit the inner wall of the patient's chest wall, and the other end of the drainage catheter is shaped and bent to fit the skin on the surface of the patient's chest wall.

[0010] Compared with the prior art, this utility model provides a flexible and shape-adjustable thoracic drainage catheter, which has the following beneficial effects:

[0011] This flexible and shape-adjustable chest drainage tube maintains its shape by shaping these molding strips. During surgery, the drainage tube can be fixed in the appropriate drainage position and secured with fixing ropes and medical tape. The intrathoracic drainage tube will not shift with the movement of the chest cavity during breathing, avoiding the drainage tube compressing the patient's ribs or lungs and causing pain. The external drainage tube can also be shaped to fit the chest wall better, reducing pressure on the insertion opening and preventing the drainage tube from kinking and causing drainage obstruction.

[0016] In the diagram: 1. Drainage tube; 2. Side hole; 3. Shaping strip; 4. Existing drainage tube; 5. Patient's chest wall; 6. Ribs; 7. Fixation rope; 8. Medical tape. Detailed Implementation

[0017] Please see Figure 1-2 A flexible and shapeable chest drainage tube includes a drainage tube 1, on which medical tape 8 is applied. The drainage tube 1 is attached and fixed to the skin of the patient's chest wall 5 by the medical tape 8. An opening is made between two ribs 6 inside the patient's chest wall 5. One end of the drainage tube 1 is inserted into the chest cavity through the opening. A fixing rope 7 is provided on the outer surface of the drainage tube 1 to fix the drainage tube 1 to the opening of the patient's chest wall 5. The characteristic feature is that multiple shaping strips 3 are provided inside the drainage tube 1 to facilitate shaping of the drainage tube 1. Multiple side holes 2 are opened on the side of the end of the drainage tube 1 that is connected to the chest bottle.

[0018] See Figure 4There are six to eight shaping strips 3, and the side holes 2 are located between two shaping strips 3. The shaping strips 3 are made of aluminum wire or other malleable metal wire. One end of the drainage tube 1 is shaped to fit the inner wall of the patient's chest wall 5, and the other end of the drainage tube 1 is shaped to fit the skin on the surface of the patient's chest wall 5. By shaping these shaping strips, the drainage tube can be kept in its original shape. During the operation, the drainage tube can be fixed in the appropriate drainage position. It is fixed with fixing rope and medical tape. The drainage tube in the inner chest will not shift with the breathing movement of the chest cavity, avoiding the drainage tube from compressing the patient's ribs or lungs and causing pain. The drainage tube in the outer chest can also be shaped to fit the chest wall better and reduce the pressure of the drainage tube on the insertion opening.

[0019] See Figure 3 An opening is made between two ribs 6 inside the patient's chest wall 5. When the existing drainage tube 4 is inserted into the patient's chest cavity through the opening, it will be perpendicular to the chest wall. After the existing drainage tube 4 is fixed by the fixing rope 7 and medical tape 8, the fixing point of the existing drainage tube 4 is prone to bending, which affects the internal communication of the drainage tube 4 and is also prone to compressing the opening of the patient's chest wall, causing the patient to suffer pain.
