Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sutureless chest tube and its components that prevent tube detachment. Background Technology

[0002] The chest tube is primarily used to drain gas, blood, pus, or other fluids from the pleural cavity to restore negative pressure and maintain respiratory function. The working principle of the chest tube is to utilize the pressure difference between the inside and outside of the pleural cavity to drain abnormally accumulated fluids and gases to the outside, thereby promoting lung re-expansion and ensuring life safety.

[0003] However, most existing chest tubes require sutures, which increases patient discomfort during insertion and removal. Due to the limited number of side holes in the chest tube, gas and fluid drainage may be delayed, affecting treatment outcomes. When administering medication, conventional chest tubes require the insertion of an indwelling needle, which can easily lead to contamination and carries the risk of the needle dislodging and gas entering through the needle hole.

[0004] Therefore, there is an urgent need to provide a sutureless chest tube and components that prevent dislodgement, which, compared to existing technologies, enhances patient comfort, improves treatment efficacy, and avoids contamination during drug injection. Utility Model Content

[0030] The length of the head 11 is 10cm, and the side wall of the head 11 is provided with a side hole 14 at a distance of 1-9cm.

[0031] like Figure 2As shown, this utility model also provides a sutureless chest tube assembly for preventing tube dislodgement, including a chest tube body 1, a fixing buckle 2, and a fixing cap 3. The fixing buckle 2 is set at the position where the patient needs to insert the chest tube body 1. The chest tube body 1 passes through the fixing buckle 2 and extends into the patient's body. The chest tube body 1 is threadedly connected to the fixing buckle 2. The fixing cap 3 is sleeved on the outside of the chest tube body 1 and the fixing buckle 2. The fixing cap 3 is threadedly connected to both the chest tube body 1 and the fixing buckle 2.

[0032] like Figure 2 , Figure 4 As shown, the fixing buckle 2 includes a fixing base 21, a threaded post 25, and a connecting assembly. The threaded post 25 is integrally connected to the fixing base 21. The threaded post 25 has an internal hollow structure, and the hollow space inside the threaded post 25 extends through the fixing base 21. There is an angle between the axis of the threaded post 25 and the perpendicular line from the fixing base 21 to the side wall of the threaded post 25, with the angle being 30°-45°. The threaded post 25 has internal and external threads. The threaded part 12 of the chest tube body 1 extends into the threaded post 25 and is threadedly connected to the threaded post 25. The fixing cap 3 is fitted over the threaded post 25 and is threadedly connected to the threaded post 25. The fixing base 21 is provided with a connecting assembly, which binds the fixing base 21 to the patient's body.

[0033] The connecting assembly includes a fixing wing 22 and a fixing strap 23. The fixing base 21 has fixing holes 24 at both ends of the side wall of the threaded post 25.

[0035] The working principle of this utility model is as follows: First, the fixed base 21 and the threaded post 25 are tied to the patient's body through the connecting assembly. The threaded post 25 is aligned with the position where the chest tube body 1 needs to be inserted. Then, one end of the head 11 of the chest tube body 1 is inserted into the threaded post 25, so that the threaded post 25 is threadedly connected to the threaded part 12 of the chest tube body 1. The length of the threaded part 12 is adjusted according to the scale set on the threaded part 12. Then, the fixed cap 3 is put on the chest tube body 1 from the tail 13. The first threaded cap 31 of the fixed cap 3 is threadedly connected to the external thread of the threaded post 25, and the second threaded cap 32 of the fixed cap 3 is threadedly connected to the threaded part 12 of the chest tube body 1, thus completing the stable connection between the fixed cap 3, the threaded post 25 and the chest tube body 1. When injecting drugs, the injection needle containing the drug is inserted into the heparin cap 15 to inject the drug into the patient's body. When the injection needle is withdrawn, the heparin cap 15 automatically seals to ensure airtightness and prevent contamination.

[0036] This invention features a fixing buckle 2, which securely fastens the patient's body. The chest tube body 1 is then passed through the fixing buckle 2 and threadedly connected to it. A fixing cap 3 is then threaded between the chest tube body 1 and the fixing buckle 2, providing double-layer fixation for the chest tube body 1. This ensures the stability of the chest tube body 1 connection and enhances patient comfort. Multiple side holes 14 eliminate the need for inserting multiple chest tube bodies 1, improving treatment efficacy. A heparin cap 15 is provided for drug administration. Upon completion of administration, the heparin cap 15 automatically seals, preventing contamination during administration.
