[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a drug analysis fluid sampling device includes a sampling tube 1, an end cap 2 installed at one end of the sampling tube 1, a sliding rod 3 that is slidably installed through the outside of the end cap 2, a piston 4 fixedly installed at one end of the sliding rod 3 and the piston 4 being located inside the sampling tube 1, a handle 6 fixedly installed at the other end of the sliding rod 3, and a spring 5 sleeved on the outside of the sliding rod 3 and the spring 5 being located between the piston 4 and the end cap 2;

[0028] The bottom of the sampling tube 1 is fixedly installed with a feeding tube 7, and the bottom end of the feeding tube 7 is provided with a collection mechanism 8.

[0029] In this embodiment, when sampling is required, the handle 906 is turned to rotate the ball 903 so that the horizontal line of the through hole 904 coincides with the horizontal line of the connecting pipe 901. At this time, the handle 6 is held to pull the slide bar 3 outward. Since the piston 4 is sealed with the sampling tube 1, the fluid drug flows into the interior of the sampling tube 1 through the connecting pipe 901. The spring 5 is compressed, and the fluid drug flows into the interior of the discharge pipe 7 due to gravity, and finally enters the interior of the sampling bottle 805 to complete the sampling. The setting of the collection mechanism 8 facilitates the filtration of the fluid drug. At the same time, the collection mechanism 8 and the discharge pipe 7 are easy to disassemble, which makes it easy to take the fluid drug inside the collection mechanism 8 for testing after disassembly, and also facilitates the cleaning of the interior of the collection mechanism 8.

[0030] In one embodiment, such as Figure 1 and Figure 3As shown, the collection mechanism 8 includes a first threaded tube 801, which is threadedly connected to the bottom end of the feed tube 7. The bottom end of the feed tube 7 has a second threaded groove 12 that matches the first threaded tube 801. A filter tube 802 is fixedly connected to the bottom end of the first threaded tube 801. A filter screen 803 is fixedly installed inside the filter tube 802. A collection component is provided at the bottom end of the filter tube 802. Rotating the filter tube 802 causes the first threaded tube 801 to rotate. Since the first threaded tube 801 matches the second threaded groove 12, it is convenient to install or remove the filter tube 802. The filter screen 803 inside the filter tube 802 can filter the fluid drug, improving the accuracy of fluid drug detection.

[0031] In one embodiment, such as Figure 3 and Figure 4 As shown, the collection assembly includes a second threaded tube 804, which is fixedly connected to the bottom end of the filter tube 802. A sampling bottle 805 is connected to the external thread of the second threaded tube 804. The top of the sampling bottle 805 has a first threaded groove 806 that matches the second threaded tube 804. When fluid drug needs to be detected, the filter tube 802 is rotated to separate the second threaded tube 804 from the sampling bottle 805. The fluid drug inside the sampling bottle 805 is then added to the detection device through a dropper. The structure is simple and convenient to use.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, one end of the sampling tube 1 is provided with a connecting mechanism 9. The connecting mechanism 9 facilitates the installation of the sampling device and the drug preparation equipment. When sampling is required, the connecting mechanism 9 is opened, and the fluid drug can enter the interior of the sampling tube 1 through the connecting tube 901. When the connecting mechanism 9 is closed, the flowing drug cannot pass through the connecting tube 901, which is convenient for adjustment according to actual needs.

[0033] In one embodiment, such as Figure 5 As shown, the connecting mechanism 9 includes a connecting pipe 901, which is fixedly installed at one end of the sampling pipe 1. A flange 902 is fixedly connected to one end of the connecting pipe 901. The flange 902 and bolts facilitate the installation of the connecting pipe 901 with the drug preparation equipment.

[0034] In one embodiment, such as Figure 5As shown, a ball 903 is rotatably mounted inside the connecting pipe 901. A through hole 904 is provided on the outside of the ball 903. A connecting rod 905 is fixedly connected to the top of the ball 903. The top of the connecting rod 905 passes through the connecting pipe 901 and is connected to a crank 906. When the connecting mechanism 9 needs to be opened, the crank 906 is turned to drive the connecting rod 905 to rotate. The connecting rod 905 drives the ball 903 to rotate, so that the horizontal line of the through hole 904 coincides with the horizontal line of the connecting pipe 901. At this time, the connecting mechanism 9 is opened. When the connecting mechanism 9 needs to be closed, the ball 903 is rotated until the horizontal line of the through hole 904 is perpendicular to the horizontal line of the connecting pipe 901.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the top of the sampling tube 1 is provided with a cleaning component, which includes an air inlet pipe 10. The air inlet pipe 10 is fixedly installed on the top of the sampling tube 1. When the sampling device needs to be cleaned, the air inlet pipe 10 is connected to an air pump. The air pump works to introduce air into the interior of the sampling tube 1. The rapidly flowing air can blow out the fluid drug inside the sampling tube 1, thus achieving a rapid cleaning effect.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, a fixing component is provided at the top of the sampling tube 1 and on one side of the air inlet pipe 10. The fixing component includes a knob 11, which is threaded to the top of the sampling tube 1. When the sampling device needs to be cleaned, the piston 4 is moved to the right side of the knob 11, and the knob 11 is rotated so that the knob 11 moves downward. The knob 11 blocks the piston 4. At this time, the piston 4 will not return to its original position when the handle 6 is released.

[0037] The above embodiment discloses a drug analysis fluid sampling device. When sampling is required, rotating the handle 906 causes the ball 903 to rotate, so that the horizontal line of the through hole 904 coincides with the horizontal line of the connecting pipe 901. At this time, holding the handle 6 pulls the slide rod 3 outward. Since the piston 4 is sealed with the sampling tube 1, the fluid drug flows into the interior of the sampling tube 1 through the connecting pipe 901. The spring 5 is compressed, and the fluid drug flows into the interior of the feed pipe 7 due to gravity, and finally enters the interior of the sampling bottle 805, completing the sampling. Slowly releasing the handle 6, due to the reset action of the spring 5, causes the piston 4 to reset, and excess fluid drug is squeezed back into the system. In the pharmaceutical equipment, the connecting mechanism 9 is closed, and the filter tube 802 is rotated to separate the second threaded tube 804 from the sampling bottle 805. The fluid drug inside the sampling bottle 805 is added to the detection device through the dropper. When the sampling device needs to be cleaned, the piston 4 is moved to the right side of the knob 11, and the knob 11 is rotated to move the knob 11 downward. The knob 11 blocks the piston 4. At this time, the piston 4 will not return to its original position when the handle 6 is released. The air inlet pipe 10 is connected to the air pump. The air pump works to introduce air into the interior of the sampling tube 1. The rapidly flowing air can blow out the fluid drug inside the sampling tube 1, which plays a role in rapid cleaning.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
