Description
Technical Field
The application relates to a drainage bag especially relates to a drainage bag convenient to sample.
Background
As shown in figure 1, the upper end of a bag body 10 of the existing drainage bag for thoracocentesis and abdominal puncture is connected with a pipeline 11 connected with a drainage tube, and the lower end of the bag body is provided with a discharge port 12, so that drainage liquid in the bag body is discharged when the bag body 10 is full. If a test is to be performed on the drainage fluid, it is conventional practice to discharge the drainage fluid into a container through the discharge port 12 and then push it into a test tube after the drainage fluid in the container is aspirated by a syringe and tested in a test chamber. In the process, due to the intervention of the syringe and the container, the operation is complicated, and the risk of sample contamination is increased.

In view of the above, the present application aims to provide a drainage bag that facilitates sampling.
The drainage bag convenient for sampling comprises a bag body, a discharge port and a sampling interface;
the sampling interface comprises a base, a baffle, a thread combination table, a hollow steel needle, a rubber tube and a cover cap;
the base is fixedly formed at the bottom of the bag body; the baffle is integrally formed at the lower end of the base; the thread combination platform is integrally formed at the lower side of the baffle plate, and external threads are formed on the periphery of the thread combination platform; the hollow steel needle penetrates through the thread combination table, the baffle plate and the base, the upper end of the hollow steel needle is communicated with the interior of the bag body, and the lower end of the hollow steel needle extends downwards to exceed the thread combination table; the rubber tube is arranged by surrounding the lower end of the hollow steel needle, the upper end of the rubber tube is fixed on the lower surface of the thread combination table, and the lower end of the rubber tube extends beyond the lower end of the hollow steel needle and is closed; the upper end of the cap is open, and the lower end is closed; the inner periphery of the cap is provided with internal threads to be combined with the outer peripheral surface of the thread combination table; the diameter of the baffle is larger than that of the thread combination table.
Preferably, the discharge port and the sampling interface are respectively positioned at two ends of the bottom end of the bag body.
Preferably, the hollow steel needle penetrates through the centers of the threaded joint table, the baffle plate and the base.
The utility model provides a drainage bag convenient to sample just can sample with the test tube is directly inserted on the steel needle through set up the hollow steel needle that uses with the cooperation of vacuum test tube on the bag body, avoids using the link of container and syringe, and not only convenient but also guaranteed that the sample is not contaminated.

Detailed Description
The drainage bag for facilitating sampling according to the present application will be described in detail with reference to the accompanying drawings.
The drainage bag convenient for sampling of the application comprises a bag body 10 and a discharge port 12, and further comprises a sampling interface 13. The structure of a vacuum blood taking needle frequently used for clinical blood taking is used as a reference for the sampling interface.
The sampling interface 13 comprises a base 13a, a baffle 13b, a thread combination table 13c, a hollow steel needle 13e, a rubber tube 13d and a cap 14.
The base 13a is fixedly formed at the bottom of the bag body 10.
A baffle 13b is integrally formed at the lower end of the base 13 a.
A screw-coupling boss 13c is integrally formed on the lower side of the baffle 13b, and a male screw is formed on the outer circumference of the screw-coupling boss 13 c.
The hollow steel needle 13e penetrates through the screw coupling table 13c, the baffle 13b, and the base 13a, and has an upper end communicating with the inside of the bag body 10 and a lower end extending downward beyond the screw coupling table 13 c.
The rubber tube 13d is provided so as to surround the lower end of the hollow steel needle 13e, the upper end of the rubber tube 13d is fixed to the lower surface of the screw-coupling table 13c, and the lower end of the rubber tube 13d extends beyond the lower end of the hollow steel needle 13e and is closed.
The upper end of the cap 14 is open, and the lower end is closed; an inner periphery of the cap 14 is formed with a female screw to be coupled with an outer peripheral surface of the screw coupling table 13 c.
The diameter of the baffle 13b is larger than that of the screw-coupling boss 13 c.
The discharge port 12 and the sampling port 13 are respectively located at two ends of the bottom end of the bag body 10.
The hollow steel needle 13e penetrates the center of the screw joint 13c, the baffle 13b, and the base 13 a.
During the use, when needing the sample, at first unscrew the block, then aim at the lower extreme of rubber tube with the rubber block of vacuum test tube, hold baffle or base for hollow steel needle in the rubber tube pierces through and gets into in the test tube behind the rubber block of rubber tube and test tube, from this, the internal drainage liquid of bag just gets into the test tube via hollow steel needle. After the sampling amount is enough, the hollow steel needle is pulled out of the test tube, the rubber tube is restored to the original state under the elasticity of the rubber tube, the hollow steel needle is sealed in the rubber tube again, and the cap is screwed on the thread combination table again.
