[0025] Reference Figures 1 to 3 The utility model of the chest closed drainage bottle is made into the following embodiments:

[0026] A closed chest drainage bottle comprises a liquid collecting bottle 100, a water sealing bottle 200 and a pressure regulating bottle 300.

[0027] The liquid collection bottle 100, water seal bottle 200, and pressure regulating bottle 300 are interconnected in sequence. The top of the liquid collection bottle 100 has a drainage port 110, and the pressure regulating bottle 300 has a suction port 310 connected to a negative pressure generating element. The water seal bottle 200 is used for water sealing. The pressure regulating bottle 300 is equipped with a pressure regulating tube 320 that connects to the outside world. The side of the liquid collection bottle 100 has a liquid discharge port 120 that also connects to the outside world.

[0028] In actual use, the negative pressure generating element generates negative pressure at the suction port 310, creating a low pressure state within the fluid collection bottle 100, the water seal bottle 200, and the pressure regulating bottle 300. The drainage port 110 drains the patient's pleural effusion through the drainage tube. The effusion flows from the drainage port 110 and is stored in the fluid collection bottle 100. When the effusion requires expansion or sampling, it can be discharged from the drain port 120, facilitating operation and preventing contamination of the drainage tube.

[0029] In this embodiment, the liquid collecting bottle 100, the water seal bottle 200, and the pressure regulating bottle 300 are flush with each other. The water seal bottle 200 is disposed between the liquid collecting bottle 100 and the pressure regulating bottle 300. A first connecting pipe 210 is disposed between the liquid collecting bottle 100 and the water seal bottle 200. A second connecting pipe 330 is disposed between the water seal bottle 200 and the pressure regulating bottle 300.

[0030] A certain amount of physiological saline is placed in both the water seal bottle 200 and the pressure regulating bottle 300. One end of the first connecting tube 210 is connected to the upper end of the liquid collecting bottle 100, and the other end of the first connecting tube 210 extends below the liquid level in the water seal bottle 200. Both ends of the second connecting tube 330 are connected to the upper ends of the water seal bottle 200 and the pressure regulating bottle 300, respectively. The upper end of the pressure regulating tube 320 is connected to the outside of the pressure regulating bottle 300, and the lower end of the pressure regulating tube 320 extends below the liquid level in the pressure regulating bottle 300.

[0031] During the drainage process, the air in the liquid collection bottle 100 is drawn into the water seal bottle 200 along the first connecting tube 210, and then discharged from the pressure regulating bottle 300 along the second connecting tube 330. The water seal bottle 200 can both clean the exhausted air and prevent back suction from occurring in the first connecting tube 210. When the drainage tube or drainage port 110 becomes blocked, external air can be drawn into the pressure regulating bottle 300 along the pressure regulating tube 320, preventing the negative pressure continuously generated by the suction port 310 from damaging the patient's chest cavity, thereby enhancing the safety of drainage.

[0032] In this embodiment, in order to facilitate observation of drainage conditions, the liquid collecting bottle 100, the water seal bottle 200 and the pressure regulating bottle 300 are all made of transparent materials. Furthermore, in order to display the liquid capacity in the bottle, the bottle bodies of the liquid collecting bottle 100, the water seal bottle 200 and the pressure regulating bottle 300 have scale markings. In this embodiment, the liquid collecting bottle 100, the water seal bottle 200 and the pressure regulating bottle 300 can be made of transparent grades of polyetheretherketone (PEEK). Polyetheretherketone is a functional polymer material that can be used to produce high-strength transparent plastic parts of different shapes through injection molding using an injection molding machine with a high pitch ratio. In other embodiments, the materials of the liquid collecting bottle 100, the water seal bottle 200 and the pressure regulating bottle 300 can also be: transparent polyphenylene terephthalate (PHB), polyphenylene (commonly known as "transparent benzene"), high-strength organic glass (polymethyl acrylate), polyphenylene terephthalamide (polyarylene terephthalate), etc.

[0033] The end of the first connecting tube 210 preferably extends 1 to 2 cm below the water surface of the water seal bottle 200, or the water seal bottle 200 is filled with physiological saline until it covers the opening of the first connecting tube 210 by 1 to 2 cm. The lower end of the pressure regulating tube 320 preferably extends 8 to 12 cm below the water surface of the pressure regulating bottle 300, or the pressure regulating bottle 300 is filled with physiological saline until it covers the lower end of the pressure regulating tube 320 by 8 to 12 cm.

[0034] In this embodiment, the heights of the liquid collecting bottle 100, the water seal bottle 200, and the pressure regulating bottle 300 are flush, and the liquid collecting bottle 100, the water seal bottle 200, and the pressure regulating bottle 300 are fixedly connected to each other. The liquid collecting bottle 100 and the pressure regulating bottle 300 are respectively arranged on both sides of the water seal bottle 200. To facilitate the use of the closed chest drainage bottle, the liquid collecting bottle 100 and the pressure regulating bottle 300 are each provided with a hook 510 on the side away from each other, and the closed chest drainage bottle can be hung and fixed by the hook 510. The bottom of the liquid collecting bottle 100 and the pressure regulating bottle 300 are both provided with a base 520. The base 520 includes at least two legs. The legs are in the shape of long strips. The two legs are rotatably hinged to each other.

[0035] The two legs are hinged at their midpoints and rotatably connected to the liquid collecting bottle 100 or the pressure regulating bottle 300. The legs are preferably longer than the widths of the liquid collecting bottle 100 and the pressure regulating bottle 300. When the legs are rotated and unfolded, they enhance stability and prevent tipping. The legs can also be rotated and folded, avoiding excessive space usage and enhancing flexibility.

[0036] To facilitate drainage, the drainage port 120 is connected to a drainage conduit 130. The drainage conduit 130 is made of a soft material, specifically silicone rubber or polyurethane. One end of the drainage conduit 130 communicates with the drainage port 120, and the other end is provided with a connector 131 for connecting to an external drainage bag. To prevent leakage, the drainage conduit 130 is provided with a tube clamp 132. When drainage is not required, the tube clamp 132 secures the drainage conduit 130 to prevent the accumulated fluid from flowing out of the collection bottle 100.

[0037] In this embodiment, a protective box 400 is provided outside the liquid collection bottle 100 to protect the drainage port 120 and drainage conduit 130 from contamination by accumulated liquid. The protective box 400 comprises a box body 410 and a cover plate 420. The box body 410 is hollow and rectangular. It encloses a rectangular protective space within which the drainage conduit 130 is located. The box body 410 has an open opening on the side facing away from the liquid collection bottle 100, and the cover plate 420 is closably positioned within the opening.

[0038] In this embodiment, one end of the cover plate 420 is rotatably hinged to the lower end of the box body 410 via a pin 421, so that the cover plate 420 has a rotation axis extending left and right, and the cover plate 420 can be flipped up and down relative to the box body 410. The other end of the cover plate 420 is provided with a lock 422. The upper end of the box body 410 is provided with a hook lock 411 corresponding to the lock 422. When drainage is required, the cover plate 420 can be opened and flipped downward to expose the drainage catheter 130 in the protective box 400, and expansion or sampling can be performed by connecting the drainage bag. When drainage is not required, the cover plate 420 is flipped upward to seal the opening of the box body 410, isolating the drainage catheter 130 in the protective box 400 to avoid contamination.

[0039] Specifically, the hook lock 411 includes: a locking rod 412, a locking hook 413 and an elastic connection portion 414. The middle part of the locking rod 412 has a hinged portion. The hinged portion is rotatably hinged to the box body 410. The locking hook 413 and the elastic connection portion 414 are respectively provided at both ends of the locking rod 412. The elastic connection portion 414 is elastically connected to the box body 410, so that the elastic connection portion 414 has a tendency to flip upward relative to the box body 410, and the locking hook 413 is elastically pressed toward the box body 410. When the cover 420 is closed, the lock buckle 422 can be inserted between the lock hook 413 and the box body 410, and the lock hook 413 can elastically press and clamp the lock buckle 422, so that the cover 420 can remain in a closed state. When the cover 420 needs to be opened, the locking hook 413 can be tilted upward and disengaged from the locking buckle 422 by pressing the elastic portion 414 .

[0040] In this embodiment, the box body 410 is further provided with a guide groove 415. The drainage conduit 130 is movably embedded in the guide groove 415. The drainage conduit 130 can be restrained by the guide groove 415 to prevent shaking. Furthermore, the cover 420 is provided with a vibration-damping pad 423. The vibration-damping pad 423 is aligned with the guide groove 415. When the cover 420 is closed, the vibration-damping pad 423 can press the drainage conduit 130 into the guide groove 415.

[0041] Furthermore, to prevent the cover 420 from shaking and causing obstruction when in the open state, an elastic connection between the cover 420 and the box body 410 is preferably provided. In this embodiment, an elastic member 430 is provided between the cover 420 and the box body 410. One end of the elastic member 430 is connected to the cover 420, and the other end is eccentrically connected to the hinge between the box body 410 and the cover 420. When the cover 420 is opened and flipped to the lower side of the box body 410, the elastic member 430 can tighten the cover 420 to prevent it from shaking. The elastic member 430 can be a torsion spring, a tension spring, an elastic rubber band, etc.
