[0028] Example 1

[0029] like Figures 1 to 6 The water-seal bottles shown do not affect the measurement statistics after being poured out, including bottle I 1, bottle II 2, and bottle III 3. The inner cavity of bottle I 1 is a effusion chamber 10, the inner cavity of bottle II 2 is a water-seal chamber 20, and the inner cavity of bottle III 3 is a pressure-regulating chamber 30. Bottle I 1 is equipped with a drainage tube 14, one end of which is connected to the patient's chest cavity, and the other end is connected to the effusion chamber 10. Bottle II 2 is equipped with a water-seal tube 21, one end of which extends into the liquid in the water-seal chamber 20, and the other end is connected to the effusion chamber 10. Bottle III 3 is equipped with a gas delivery tube 22, a pressure-regulating tube 31, and a negative pressure tube 32. The two ends of the gas delivery tube 22 are connected to the water-seal chamber 20 and the pressure-regulating chamber 30, respectively; one end of the pressure-regulating tube 31 extends into the liquid in the pressure-regulating chamber 30, and the other end is connected to the outside air; one end of the negative pressure tube 32 is connected to the existing suction machine, and the other end is connected to the pressure-regulating chamber 30. The pleural effusion chamber 10 includes a small effusion chamber 11 with a capacity of 100 ml, a medium effusion chamber 12 with a capacity of 600 ml, and a large effusion chamber 13 with a capacity of 1500 ml. The side walls of the small effusion chamber 11, the medium effusion chamber 12, and the large effusion chamber 13 are all made of transparent material and are marked with capacity graduations. Pleural fluid flows into the effusion chamber 10 through the drainage tube 14 and fills the small effusion chamber 11, the medium effusion chamber 12, and the large effusion chamber 13 in sequence.

[0030] Reference Figure 1 , Figures 4 to 6The small-accumulation cavity 11 is provided with an A valve piece 15 for preventing liquid in the small-accumulation cavity 11 from flowing out: when liquid flows into the small-accumulation cavity 11, the A valve piece 15 elastically deforms and the small-accumulation cavity 11 opening is opened; when liquid flows out of the small-accumulation cavity 11, the A valve piece 15 restores to the original state and the small-accumulation cavity 11 opening is closed. The medium-accumulation cavity 12 is provided with a B valve piece 16 for preventing liquid in the medium-accumulation cavity 12 from flowing out: when liquid flows into the medium-accumulation cavity 12, the B valve piece 16 elastically deforms and the medium-accumulation cavity 12 opening is opened; when liquid flows out of the medium-accumulation cavity 12, the B valve piece 16 restores to the original state and the medium-accumulation cavity 12 opening is closed. By closing the small-accumulation cavity 11 opening through the A valve piece 15 and closing the medium-accumulation cavity 12 opening through the B valve piece 16, the liquid in the liquid-accumulation cavity 10 is prevented from flowing randomly between the small-accumulation cavity 11, the medium-accumulation cavity 12 and the large-accumulation cavity 13, achieving the purpose of not affecting the measurement and statistics after the water seal bottle is poured.

[0031] The small-accumulation cavity 11 is in the shape of an "I", the medium-accumulation cavity 12 and the large-accumulation cavity 13 are both in the shape of a "7", the small-accumulation cavity 11, the longitudinal part of the medium-accumulation cavity 12 and the longitudinal part of the large-accumulation cavity 13 are arranged in sequence in the horizontal direction, and the transverse part of the small-accumulation cavity 11, the transverse part of the medium-accumulation cavity 12 and the transverse part of the large-accumulation cavity 13 are arranged in sequence in the vertical direction: as shown in FIG. 1, when the pleural effusion flows into the liquid-accumulation cavity 10 through the drainage tube 14, the medium-accumulation cavity 12 opening and the small-accumulation cavity 11 opening are opened in sequence; as shown in FIG. 2, when the small-accumulation cavity 11 is filled with liquid, the liquid in the small-accumulation cavity 11 pushes upwardly against the A valve piece 15, causing the A valve piece 15 to close the small-accumulation cavity 11 opening; as shown in FIG. 3, when the medium-accumulation cavity 12 is filled with liquid, the liquid in the medium-accumulation cavity 12 pushes upwardly against the B valve piece 16, causing the B valve piece 16 to close the medium-accumulation cavity 12 opening. Figure 4 Figure 5 Figure 6

[0032] Referring to FIGS. 1, 2 and 3, Figure 1 Figure 4 The transverse part of the large-accumulation cavity 13 is provided with a water-blocking piece 17 for blocking the flow of the pleural effusion to the longitudinal part of the large-accumulation cavity 13, the water-blocking piece 17 is arranged in the middle of the medium-accumulation cavity 12 opening and the longitudinal part of the large-accumulation cavity 13, and the upper surface of the water-blocking piece 17 is higher than the medium-accumulation cavity 12 opening. By the water-blocking piece 17, the pleural effusion is prevented from flowing into the longitudinal part of the large-accumulation cavity 13 when the medium-accumulation cavity 12 is not filled, improving the accuracy of the measurement and statistics.

[0033] The medium-accumulation cavity 12 opening is in the shape of an inverted isosceles trapezoid, and the inner diameter of the medium-accumulation cavity 12 opening gradually decreases from top to bottom. The medium-accumulation cavity 12 opening plays a transition role, guiding the flow of the pleural effusion into the medium-accumulation cavity 12.

[0034] ​​​​The opening of the small pleural cavity 11 is an inverted right-angled trapezoid. The side wall of the opening of the small pleural cavity 11 near the longitudinal part of the middle pleural cavity 12 is inclined. The inner diameter of the opening of the small pleural cavity 11 gradually decreases from top to bottom. The opening of the small pleural cavity 11 serves as a transition, guiding pleural effusion into the small pleural cavity 11.

[0035] Example 2

[0036] like Figure 7 The water-sealed bottle shown does not affect the measurement statistics after being poured out. This embodiment is based on Embodiment 1, but the difference between this embodiment and Embodiment 1 is:

[0037] An infusion channel 4 is provided in the horizontal part of the large pleural cavity 13. The infusion channel 4 is in the shape of an "I". The end of the infusion channel 4 away from the vertical part of the large pleural cavity 13 has a tube opening 40. A storage tank 41 is provided on the lower wall of the infusion channel 4 at the tube opening 40. The opening of the storage tank 41 faces upward. The drainage tube 14 is located in the infusion channel 4. Pleural fluid flows into the storage tank 41 through the infusion channel 4. A core insertion port 43 is provided on the top of bottle I. The core insertion port 43 is located directly above the storage tank 41. A rubber core 42 is provided in the core insertion port 43. An existing syringe needle can puncture the rubber core 42 to enter the storage tank 41 and draw pleural fluid samples. Pleural fluid accumulates in the storage tank 41 through the infusion channel 4. Nurses can use an existing syringe needle to puncture the rubber core 42 on the top of bottle I and draw pleural fluid from the storage tank 41, which is convenient for sampling. The infusion channel 4 serves as a drainage channel, allowing pleural effusion to fill the storage tank 41 before flowing out of the infusion channel 4 port 40 for sampling. The infusion channel 4 port 40 faces away from the longitudinal part of the large accumulation cavity 13 and is far away from the longitudinal part of the large accumulation cavity 13 to prevent pleural effusion from entering the accumulation cavity 10 and flowing directly into the longitudinal part of the large accumulation cavity 13.

[0038] The bottle 1 has a raised ring 44 that surrounds the core inlet 43 and is higher than the rubber core 42. The raised ring 44 protrudes from the bottle 1 and limits the puncture range of the syringe needle, allowing the nurse to clearly see the location of the rubber core 42, quickly find the puncture site, and improve work efficiency.
