Description

Technical Field

[0001] The utility model relates to the technical field of drug detection equipment, in particular to a sampling device for drug detection. Background Art

[0002] In order to ensure the safety of drugs, multiple tests are required before the drugs are officially put into use. Before drug testing, it is necessary to sample the drugs. Therefore, a drug sampling device is needed to collect and sample the drugs to be tested.

[0003] When sampling and testing liquid medicine type drugs, it is often necessary to sample different or multiple bottles of liquid medicine. In order to avoid other liquid medicine being mixed in the sampling device during sampling, the sampling device needs to be cleaned once before each sampling, or multiple sampling devices need to be used for sampling, resulting in a waste of sampling resources, and more time is also required to clean the sampling device later, which brings certain inconvenience to drug sampling. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a sampling device for drug detection, which solves the problem that the existing sampling device in the prior art is not convenient for sampling different types of drugs.

[0009] Further, the sealing seat is made of rubber material, and an anti-slip pad is provided on the side wall of one end of the storage tube where the sealing seat is located.

[0010] Further, a limiting component is provided on the top of the sealing seat for limiting the disconnection of the connecting pipe and the exhaust pipe.

[0011] Furthermore, the limiting component includes: a torsion spring, a pressure rod, and a limiting post. The pressure rod is obliquely arranged above the sealing seat. The torsion spring is connected between the pressure rod and the sealing seat. The limiting post is fixed on the side wall of the pressure rod. An installation seat is fixedly arranged on the side wall of the connecting pipe, and a limiting groove is provided on the top of the installation seat.

[0020] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0021] As Figure 1 shown, an embodiment of the utility model provides a sampling device for drug detection, including: a storage tube 1 and an installation cylinder 5. The top of the storage tube 1 is open, and a sealing seat 2 for sealing it is arranged at the opening. A sampling tube 4 and an exhaust pipe 3 for communicating the outside with the inside of the storage tube 1 are arranged on the sealing seat 2. One end of the installation cylinder 5 is open, and a piston assembly is arranged at the open end of the installation cylinder 5. A connecting pipe 6 for inserting into the exhaust pipe 3 is communicated with the closed end of the installation cylinder 5.

[0022] By inserting the connecting pipe 6 into the exhaust pipe 3, and both the connecting pipe 6 and the exhaust pipe 3 are rubber hoses, that is, a connecting pipe 6 and an exhaust pipe 3 with appropriate specifications are selected to make the connecting pipe 6 and the exhaust pipe 3 in dynamic sealing connection. Then one end of the sampling tube 4 is inserted into the liquid medicine bottle to be sampled. The piston assembly draws the air in the storage tube 1 through the connecting pipe 6 and the exhaust pipe 3. Thus, under the action of air pressure, the sampling tube 4 sucks the liquid medicine in the liquid medicine bottle into the storage tube 1. The sampling of the liquid medicine is realized in the above way, avoiding the piston assembly directly sucking the liquid medicine and causing the liquid medicine to contaminate the piston assembly, which affects the piston assembly's sucking of the next bottle of liquid medicine, thereby improving the sampling efficiency of different liquid medicines.

[0023] Specifically, the piston assembly includes: a connecting part 8, an installation part 9 and a sliding plug 7. The sliding plug 7 is in dynamic sealing connection with the installation cylinder 5. The connecting part 8 is fixed on the top of the sliding plug 7. The installation part 9 is located on the top of the connecting part 8, and the cross-section of the installation part 9 is larger than the cross-section of the installation cylinder 5, so as to realize the support of the installation part 9 for the connecting part 8 and the sliding plug 7. In order to facilitate pulling the connecting part 8 and the sliding plug 7, a pull ring 10 is arranged on the top of the installation part 9; at the same time, in order to prevent the connecting pipe 6 and the exhaust pipe 3 from separating during the process of sucking the liquid medicine, a limiting component for restricting the separation of the connecting pipe 6 and the exhaust pipe 3 is arranged on the top of the sealing seat 2.

[0024] Furthermore, as Figure 3 shown, the limiting component includes: a torsion spring 11, a pressing rod 12 and a limiting column 13. The pressing rod 12 is obliquely arranged above the sealing seat 2. The torsion spring 11 is connected between the pressing rod 12 and the sealing seat 2. The limiting column 13 is fixed on the side wall of the pressing rod 12. An installation seat 14 is fixedly arranged on the side wall of the connecting pipe 6, and a limiting groove is arranged on the top of the installation seat 14. Under the elastic force of the torsion spring 11, the limiting column 13 is inserted into the limiting groove; through the above structure, the pressing rod 12 presses the limiting column 13 tightly in the limiting groove under the elastic force of the torsion spring 11, thereby preventing the connecting pipe 6 and the exhaust pipe 3 from separating.

[0025] As Figure 3As shown in the figure, it further includes: a storage box 15, a storage seat 16 is arranged inside the storage box 15, and a plurality of storage grooves 17 for inserting the storage tube 1 are arranged at the top of the storage seat 16. A hook 18 is arranged on the inner wall of the storage box 15, and the hook 18 is used for hanging the pull ring 10.

[0026] Specifically, an installation groove is arranged beside each of the storage grooves 17. A spring 19 and an identification column 20 are arranged in the installation groove, and under the elastic force of the spring 19, the identification column 20 extends out of the installation groove. A limiting mechanism is arranged on one side of each installation groove, and the limiting mechanism is used to block the identification column 20 from extending out of the installation groove. Each of the limiting mechanisms includes: a limiting block 21, the limiting block 21 is rotatably arranged on the top of the storage seat 16 through a rotating shaft 22, and the limiting block 21 is used to press tightly above the identification column 20.

[0027] Through the arrangement of the identification column 20, after the storage tube 1 containing the liquid medicine is inserted into the storage groove 17, rotate the limiting block 21 so that the limiting block 21 no longer restricts the identification column 20. Under the elastic force of the spring 19, the identification column 20 extends out of the installation groove, so that the staff can clearly judge whether the storage tube 1 contains liquid medicine, avoiding mistakes of the staff.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
