Description

Technical Field

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

[0002] Allopurinol is a white or off-white crystalline powder, almost odorless. Allopurinol is mainly used between gout attacks and in the chronic stage. It is suitable for primary and secondary gout patients with excessive uric acid production, allergic to or ineffectiveness to uricosuric drugs, and those who are not suitable for uricosuric drugs, to control hyperuricemia. It can also be used in combination with uricosuric drugs to enhance the therapeutic effect. It is particularly suitable for patients with severe tophi but good renal function. Generally, allopurinol needs to be tested for quality during the production process.

[0003] For example, a sample sampling device for drug testing with publication number CN216870099U, through the cooperation of the sleeve, movable bin, limit rod, limit block, spring, limit groove and handle, two sets of limit rods are quickly embedded in or leave the limit groove under the action of the spring, so that the limit rod is quickly released or forms a limiting effect on the sampling head, avoiding the problem that the disposable sampling head may fall off during use and the need to reinstall a new disposable sampling head, thereby improving the practicality of the device. However, in actual use, allopurinol needs to be crushed, filtered, dissolved and diluted during the detection process, and then the drug solution is sampled. During the sampling process of the drug solution, the allopurinol concentration in the drug solution is not the same. If sampling is performed directly, it is easy to cause inaccurate sampling. Sampling needs to be performed at multiple points during the sampling process. The sampling process is relatively cumbersome. If stirring is performed before sampling, if sampling is performed after stirring, the inside of the drug solution may return to a static state, and inaccurate sampling is still likely to occur, which is easy to affect the accuracy of subsequent detection, and there are certain usage defects.

[0026] 1. A rotating assembly is provided on the outside of the cylinder. When testing the allopurinol solution, the tablets need to be crushed, filtered, dissolved and diluted. For sampling, the support frame is placed inside the liquid medicine container, the piston is located at the bottom of the cylinder, the fixing ring on the cylinder is fitted with the mounting ring, the positioning block is inserted into the positioning groove, the sampling tube is immersed in the liquid medicine, and then the movable plate can be fitted with the mounting head, so that the rack on the L-shaped rod and the rotating gear are meshed with each other, and then the cylinder can be pressed with one hand to prevent the cylinder from moving, and then the two fingers of the other hand can be fitted with the bottom of the mounting head, the mounting head is lifted upward to drive the mounting rod to move, so that the piston moves inside the cylinder, and the liquid medicine can be drawn into the cylinder through the sampling tube. The mounting head can drive the movable plate to move while moving upward, and the movement of the movable plate drives the L-shaped rod to move. After the L-shaped rod moves The meshing of the rack and the rotating gear can drive the rotating shaft to rotate, and after the rotating shaft rotates, the meshing of the first bevel gear and the second bevel gear can drive the rotating rod to rotate, and after the rotating rod rotates, the hollow rod can be driven to rotate through the cooperation of the connecting groove and the connecting strip, and after the hollow rod rotates, the rotating blade is driven to rotate, so that the liquid medicine can be mixed to avoid uneven concentration of the liquid medicine, and the sampling accuracy of the liquid medicine can be improved. The stirring rate is controlled by the movement of the mounting rod to avoid the generation of bubbles due to excessive stirring rate.

The liquid medicine is drawn into the cylinder body 1 through the sampling tube 101, and the mounting head 104 can drive the movable plate 203 to move while moving upward, and the movement of the movable plate 203 drives the L-shaped rod 204 to move, and after the L-shaped rod 204 moves, the engagement of the rack 209 with the rotating gear 208 drives the rotating shaft 207 to rotate, and after the rotating shaft 207 rotates, the engagement of the first bevel gear 210 with the second bevel gear 213 drives the rotating rod 212 to rotate, and after the rotating rod 212 rotates, the hollow rod 215 can be driven to rotate through the cooperation of the connecting groove 219 and the connecting strip 218, and after the hollow rod 215 rotates, the rotating blade 216 is driven to rotate, so that the liquid medicine can be mixed, and the uneven concentration of the liquid medicine can be avoided, and the sampling accuracy of the liquid medicine can be improved, and the stirring rate is controlled by the movement of the mounting rod 103 to avoid the generation of bubbles caused by too fast stirring rate;

[0056] The rotating rod 212 can drive the cam 220 to rotate during the rotation process. After the cam 220 rotates, the movable rod 222 can be pushed to slide on the fixed block 221. After the movable rod 222 moves, the reset spring 224 can be stretched. After the cam 220 rotates one circle, it is reset under the action of the reset spring 224. Then, the rotating rod 212 can drive the movable rod 222 to move back and forth. After the movable rod 222 moves, it drives the moving block 233 to move. After the moving block 233 moves, it is connected to the column 231 through the sliding groove 234. The sliding connection of 2 can drive the vertical rod 231 to move upward. After the vertical rod 231 moves upward, it drives the limiting ring 226 to move through the positioning rod 229. The limiting ring 226 can drive the hollow rod 215 to move, and the hollow rod 215 drives the supporting ring 228 to rotate in the annular groove 227 to limit the position during the rotation process, so that the hollow rod 215 can reciprocate up and down during the rotation process, thereby expanding the stirring range, stirring the liquid medicine of different depths, and further improving the uniformity of the liquid medicine. To improve the sampling accuracy, when sampling, the user lifts the mounting head 104 with his fingers to press the pressing block 238, and the pressing block 238 can push the sliding rod 236 to move. After the sliding rod 236 moves, the movable block 239 can be pushed to slide on the shell 235 through the connecting rod 240, and the upper sides of the inner side of the mounting groove 2031 on the movable plate 203 are arc-shaped. After the movable block 239 moves, it squeezes the mounting groove 2031 through its own arc-shaped edge, which can provide downward pressure on the movable plate 203, and can ensure the movable plate 203. The plate 203 is not easy to move, thereby preventing the rack 209 from disengaging from the rotating gear 208. After the sampling is completed, the movable plate 203 can be removed together with the cylinder 1. When removing the movable plate 203, the movable plate 203 can be directly pulled, and the movable block 239 can be pushed and moved through the arc edge on the installation groove 2031, so that the movable block 239 retracts into the shell 235, and the movable plate 203 can be removed, which is convenient for removing the movable plate 203. Conversely, it is also convenient for assembling the movable plate 203 and the installation head 104.
