AI Technical Summary
The existing chest drainage tubes are complicated to change and may cause the chest cavity to come into contact with outside air, increasing the risk of infection.
A chest drainage tube with a threaded sleeve and a clamping mechanism was designed. Through the cooperation of the clamping frame, clamping roller and sliding frame, the drainage tube can be automatically clamped and unlocked, simplifying the replacement process and ensuring that the drainage tube remains closed when the drainage bag is removed.
It simplifies the process of changing drainage bags, avoids contact between the chest cavity and outside air, and reduces the risk of infection.

Abstract
Claims
1. A chest drainage tube comprising a drainage chest tube and a drainage bag, characterized in that: The end of the drainage chest tube is integrally formed with a threaded sleeve. A clamping mechanism is slidably connected to the drainage chest tube. The clamping mechanism includes a clamping frame, clamping rollers, and a sliding frame. The sliding frame is slidably installed on the clamping frame. A threaded sleeve is provided at the lower end of the clamping frame. The threaded sleeve is threaded to the outer wall of the threaded sleeve. Sliding slots are provided on the left and right sides of the clamping frame. The inner walls of the left and right sides of the clamping frame are integrally formed with protruding toothed racks. The clamping roller includes a clamping shaft that slides through the sliding slot, a clamping wheel provided in the middle of the clamping shaft, and gear sleeves provided on the left and right sides of the clamping wheel. The gear sleeves mesh with the protruding toothed racks. The clamping wheel slides and abuts against the two protruding toothed racks. The bottom wall of the clamping frame is set as a clamping slope. The drainage chest tube passes through the clamping slope and the clamping wheel.
2. A chest drainage tube according to claim 1, characterised in that: The drainage bag is provided with a connecting tube, and a connecting mechanism is connected between the drainage chest tube and the connecting tube. The connecting mechanism includes a through connecting rod, a rubber conical sleeve and a connecting cap assembly. The lower end of the through connecting rod passes through the upper end of the connecting tube, the rubber conical sleeve is fitted on the end of the through connecting rod facing the drainage chest tube, and the rubber conical sleeve passes through the lower end of the drainage chest tube.
3. A chest drainage tube according to claim 2, wherein: The connecting cap assembly includes a knob cap that is rotatably fitted onto the outer wall of the top of the connecting tube and a threaded ring that is rotatably fitted onto the middle of the knob cap. The threaded ring is threadedly fitted onto the lower end of the threaded sleeve.
4. A chest drainage tube according to claim 3, wherein: A through-ring gap is provided between the knob cap and the threaded ring. Engaging vertical grooves are provided on the inner wall of the knob cap and the outer wall of the threaded ring. The lower end of the through-slide frame is rotatably connected to an through-ring sleeve. Engaging protrusions are provided on both the inner and outer walls of the through-ring sleeve. The engaging protrusions slide through the engagement vertical groove.
5. A chest drainage tube according to claim 4, wherein: The outer wall of the clamping frame is provided with a guide groove parallel to the clamping inclined surface, and the side wall of the through-slide frame is provided with a sliding groove. The clamping shaft slides through the sliding groove, and the through-slide frame is provided with a displacement slider that slides in conjunction with the guide groove.
6. A chest drainage tube according to claim 5, wherein: The top end of the connecting tube is integrally formed with an outward protruding ring, and the middle part of the through connecting rod is integrally formed with a mating ring aligned with the outward protruding ring. The lower end of the inner wall of the knob cap is provided with a positioning ring groove, which is rotatably fitted onto the outward protruding ring and the mating ring.
