[0009] Furthermore, a sealing cap is included, with the outer end of the sampling port threadedly connected to the sealing cap.

[0010] Furthermore, at least one baffle is provided in the fluid accumulation cavity.

[0011] The working principle of this utility model:

[0012] By adding a specimen chamber to the traditional water-sealed chest drainage bottle, when sampling is needed, the drainage fluid is introduced into the specimen chamber through a manually switched three-way valve. The drainage fluid accumulated in the specimen chamber is then directly extracted from the sampling port for sampling. The operation is simple, the whole process is sealed, and infection and pneumothorax are avoided.

[0013] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0014] 1. The three-way valve of this utility model introduces the drainage fluid into the specimen cavity, and then samples are taken through the sampling port. The operation is simple, the sampling process is completely closed, avoiding infection and pneumothorax, and there is no need to replace the chest drainage bottle.

[0015] 2. The specimen chamber and the fluid accumulation chamber of this utility model are connected through an overflow port, which avoids the specimen chamber being full and unable to drain when the three-way valve is not switched back.

[0016] 3. The sampling port of this utility model is equipped with a sealing membrane, which can be directly punctured to extract the drainage fluid in the specimen cavity for sampling, further simplifying the operation.

[0017] 4. A baffle is provided above the overflow port of this utility model to prevent the drainage fluid from flowing into the adjacent cavity through the overflow port when it flows into the chamber. Attached Figure Description

Detailed Implementation

[0020] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0021] like Figure 1 As shown, this embodiment provides a chest drainage bottle for easy sampling, including an effusion chamber 1, a water-seal chamber 2, and a suction control chamber 3. The effusion chamber 1, water-seal chamber 2, and suction control chamber 3 form a traditional three-chamber drainage structure. The top of the effusion chamber 1 is connected to one end of a first connecting tube 8. The other end of the first connecting tube 8 passes through the top of the water-seal chamber 2 and extends to the lower part of the water-seal chamber 2. The top of the water-seal chamber 2 is connected to the top of the suction control chamber 3 through both ends of a second connecting tube 9. The lower part of the suction control chamber 3 is connected to one end of a ventilation tube 10. The other end of the ventilation tube 10 passes through the top of the suction control chamber 3 and connects to the outside. The top of the suction control chamber 3 is connected to a suction device through a suction tube 11. This connection method is the same as that of the existing three-chamber water-seal chest drainage bottle, such as the Jingle brand disposable closed chest drainage bottle (Type III), etc. The principle will not be described in detail here.

[0022] The pleural drainage bottle of this utility model, which is convenient for sampling, also includes a long and narrow specimen cavity 4, which is adjacent to the effusion cavity 1. The top of the effusion cavity 1 is connected to a first drainage tube 101, and the top of the specimen cavity 4 is connected to a second drainage tube 401.

[0023] The chest drainage bottle convenient for sampling of the utility model further comprises a three-way valve 6 and a drainage main pipe 7, the three-way valve 6 is a commonly used medical three-way valve 6, for example, a medical three-way valve 6 of the brand of Aibel, comprising one liquid inlet end and two liquid outlet ends, the drainage main pipe 7 is in communication with the liquid inlet end, the first drainage pipe 101 and the second drainage pipe 401 are in communication with one liquid outlet end respectively, the flow direction can be adjusted by rotating the knob of the three-way valve 6, so that the drainage liquid in the drainage main pipe 7 is guided into the first drainage pipe 101 or the second drainage pipe 401.

[0024] The side wall of the specimen cavity 4 is provided with a sampling port 5, the sampling port 5 is in communication with the specimen cavity 4, and the sampling port 5 is located close to the bottom of the specimen cavity 4, so that sampling can be performed when the liquid level of the specimen cavity 4 is low due to less drainage liquid.

[0025] The specimen cavity 4 and the effusion cavity 1 are in communication through an overflow port 402, the overflow port 402 is located close to the top of the specimen cavity 4, so that the specimen cavity 4 is not full when the three-way valve 6 is not cut back, and drainage is not affected; in the embodiment, the effusion cavity 1 is divided into multiple chambers by a partition, and the overflow port 402 is also higher than the partition, so that the drainage liquid does not flow into the next chamber through the overflow port 402.

[0026] Because the overflow port 402 is in communication with the effusion cavity 1, the negative pressure in the effusion cavity 1 can make the specimen cavity 4 also in a negative pressure state through the overflow port 402, so that the drainage liquid is more easily introduced into the specimen cavity 4.

[0027] The overflow port 402 is provided with a baffle 403 on one side of the effusion cavity 1 and one side of the specimen cavity 4 respectively, the baffle 403 is inclined, and the lowest end of the baffle 403 is away from the overflow port 402, if the drainage liquid flows into the chamber along the side wall where the overflow port 402 is located, the drainage liquid can flow into the adjacent chamber through the overflow port 402, the baffle 403 is inclined and covers the overflow port 402, and the baffle 403 has a roof-like shielding effect, so that the drainage liquid is prevented from flowing into the adjacent chamber.

[0028] The use mode of the embodiment is as follows:

[0029] 1. When sampling is not needed, the three-way valve 6 is in a communication state of the drainage main pipe 7 and the first drainage pipe 101, the drainage liquid flows into the effusion cavity 1 through the first drainage pipe 101, the effusion cavity 1 performs chest drainage on the patient through the negative pressure generated by the water seal, and the chest drainage bottle is used as a conventional three-chamber water seal chest drainage bottle.

[0030] 2. When sampling is needed, the three-way valve 6 is adjusted to the state of communication between the main drainage pipe 7 and the second drainage pipe 401, at this time, the drainage liquid no longer flows into the effusion cavity 1 through the first drainage pipe 101, but flows into the sample cavity 4 through the second drainage pipe 401, and gradually accumulates in the sample cavity 4, during the accumulation process, because the sample cavity 4 is in communication with the effusion cavity 1 through the overflow port 402, the sample cavity 4 is also in a negative pressure state as the effusion cavity 1, thereby facilitating drainage.

[0031] 3. After the drainage liquid in the sample cavity 4 accumulates to a certain amount, the three-way valve 6 is manually switched back to the state of communication between the main drainage pipe 7 and the first drainage pipe 101, then the sealing cap is unscrewed, the sealing film 501 on the sampling port 5 is pierced by using a sampling needle, and the drainage liquid in the sample cavity 4 is sampled, after sampling is completed, the sealing film 501 is disinfected and sealed by screwing the sealing cap again.

[0032] 4. If the sample cavity 4 accumulates to be full, but forgets to switch back the three-way valve 6, the drainage liquid in the sample cavity 4 will overflow to the effusion cavity 1 through the overflow port 402, avoiding drainage failure or backflow of the drainage liquid.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
