Description

Technical Field

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

[0002] Synthetic drugs are drugs made by chemical synthesis or biosynthesis. Chemical synthesis includes organic synthesis and inorganic synthesis, and biosynthesis includes full biosynthesis and partial biosynthesis and partial chemical synthesis. Drug synthesis occupies an extremely important position in the pharmaceutical industry. Synthetic drugs are widely used in medical practice. When analyzing synthetic drugs, it is necessary to sample the synthetic drugs. However, the existing drug sampling is usually done manually. However, due to manual sampling, it is easy for the sampler to be subjected to uneven force, resulting in the inability to perform quantitative sampling, reducing the accuracy of drug sampling data. In addition, during the sampling process, the sampler is prone to shaking due to force, which not only reduces the stability and firmness of the sampler, but also easily causes the sampling data to have larger errors.

[0003] As disclosed in publication number CN218271553U, a drug analysis sampling device is proposed, which belongs to the technical field of sampling devices and comprises: a fixed plate, a vertical frame and an extraction cylinder; a movable plate is arranged on the outer side of the vertical frame, and the extraction cylinder is detachably connected in a groove opened on the surface of the movable plate, and the bottom surface of the extraction cylinder is connected with a needle, a piston on the inner wall of the extraction cylinder is connected with a piston block, a top end of the piston block is connected with a movable rod, and the top end of the movable rod extends to the outside of the extraction cylinder and is connected to a limiting block; a sealing frame sleeved on the outer periphery of the movable rod is connected to the top end of the extraction cylinder, and a motor three is connected to the inner wall of the sealing frame, and a gear three is connected to the output shaft of the motor three, and a gear rod meshing with the gear three is connected to the outer wall of the movable rod. The drug analysis sampling device improves the accuracy of drug sampling data.

[0004] The device is large in size and is not convenient to move or carry. After each drug sampling, the part that has been in contact with the drug needs to be cleaned or replaced to avoid contamination of other drugs during the next sampling. The extraction tube of the device is not easy to replace, so a synthetic drug analysis sampling device is proposed to solve the above problems. Utility Model Content

After each drug sampling, the part that has been in contact with the drug needs to be cleaned or replaced to avoid contamination of other drugs during the next sampling, and the extraction tube of the device is not easy to replace.

[0007] (II) Technical solution

[0008] The utility model solves the above-mentioned technical problems with the following technical solutions: A synthetic drug analysis sampling device comprises a columnar shell, a disposable syringe and a medicine bottle, wherein a partition plate adapted to the disposable syringe is fixedly connected inside the columnar shell, a lifting assembly rotatably connected to the bottom of the partition plate is provided on the inner bottom wall of the inner cavity of the columnar shell, a placement bin slidably connected to the inner side of the columnar shell and driven by the lifting assembly and adapted to the disposable syringe, a pressing assembly symmetrically distributed on the inner top wall of the placement bin and tightly fitted to the top of the medicine bottle is provided, a circular hole communicating with the inner side and adapted to the disposable syringe is provided on the top of the placement bin, a fixing plate is fixedly connected inside the columnar shell, a fixing groove adapted to the disposable syringe is provided on the front side of the fixing plate, a pull-up assembly rotatably connected to the top of the fixing plate is provided on the inner top wall of the columnar shell, a pull-up plate adapted to the disposable syringe is threadedly connected to the outer side of the pull-up assembly, and a control panel electrically connected to both the lifting assembly and the pull-up assembly is provided on the top of the columnar shell.

[0009] The beneficial effects of the utility model are as follows: the medicine bottle is loaded into the placement bin, and the medicine bottle is tightly fitted with the pressing component, the disposable syringe is loaded into the device, the finger hook portion of the disposable syringe enters the fixed groove, and the piston shaft of the disposable syringe is clamped on the front side of the pull-up plate, and then the required sampling dose is input on the control panel, so that the control panel moves the lifting component, and the lifting component drives the placement bin to move upward until the needle of the disposable syringe enters the medicine bottle and contacts the medicine, and then the control panel moves the lifting component, and the lifting component moves the pull-up plate upward, and at the same time drives the piston shaft of the disposable syringe to move upward, so that the medicine in the medicine bottle can be sampled into the disposable syringe, until the medicine entering the disposable syringe reaches the required sampling dose, the control panel stops the pull-up component, and then the control panel causes the lifting component to drive the placement bin to reset, so that the needle of the disposable syringe can be separated from the medicine bottle, and finally the disposable syringe containing the sampled medicine is taken out from the device, and the sampled medicine in the disposable syringe is transported to the analysis equipment for inspection and analysis.

[0010] The synthetic drug analysis sampling device has the advantages of small size, easy to carry and the ability to quickly replace the syringe for extracting the drug.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

The outer side of the first threaded rod is fixedly connected to a second gear that meshes with the first gear. The outer side of the first threaded rod is threadedly connected to the same placement bin, and the first stepper motor is electrically connected to the control panel.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that when the control panel makes the first stepper motor rotate, the first stepper motor drives the second gear to rotate through the first gear, and then drives the first threaded rod to rotate synchronously. The force generated by the rotation of the outer thread of the first threaded rod drives the placement bin to move upward, thereby achieving the effect of moving the medicine bottle upward so that the needle of the disposable syringe enters the medicine bottle and contacts the medicine.

[0014] Furthermore, the clamping assembly includes a clamping spring and a spherical clamping block. The top wall of the inner cavity of the placement bin is slidably connected to the spherical clamping blocks that are symmetrically distributed on the left and right. The top of the spherical clamping blocks is fixedly connected to a clamping spring fixedly connected to the placement bin, and the spherical clamping blocks are tightly fitted to the top of the medicine bottle.

[0015] The beneficial effect of adopting the above further scheme is that the medicine bottle is placed in the placement bin, and at the same time, the elastic force of the compression spring makes the bottom of the spherical compression block fit tightly with the top of the medicine bottle, thereby achieving the effect of pressing the medicine bottle into the placement bin.

[0016] Furthermore, a rubber pad adapted to the disposable syringe is fixedly connected to the bottom of the fixing groove.

[0017] The beneficial effect of adopting the above further solution is that when the finger hook portion of the disposable syringe enters the fixing groove, the friction force of the rubber pad itself and the elastic force generated by the extrusion deformation can ensure the stability of the disposable syringe when extracting samples.

[0018] Furthermore, the pulling-up assembly includes a second stepper motor, a third gear, a second threaded rod and a fourth gear. The top wall of the inner cavity of the cylindrical shell is provided with a second stepper motor. The output end of the second stepper motor is fixedly connected to the third gear.

The outer side of the second threaded rod is fixedly connected to a fourth gear meshing with the third gear. The outer side of the second threaded rod is threadedly connected to the same pulling-up plate, and the second stepper motor is electrically connected to the control panel.

[0019] The beneficial effect of adopting the above further scheme is that when the control panel rotates the second stepper motor, the second stepper motor drives the fourth gear to rotate through the third gear, and then the second threaded rod rotates synchronously. The force generated by the rotation of the thread on the outer side of the second threaded rod drives the pull-up plate to move upward, thereby driving the piston shaft of the disposable syringe to move upward, thereby achieving the effect of sucking the medicine in the medicine bottle into the disposable syringe.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the embodiment, Figure 1-4A synthetic drug analysis sampling device is provided. The utility model comprises a columnar shell 1, a disposable syringe 2 and a medicine bottle 12. A partition plate 3 adapted to the disposable syringe 2 is fixedly connected inside the columnar shell 1. A lifting assembly 4 rotatably connected to the bottom of the partition plate 3 is provided on the inner bottom wall of the inner cavity of the columnar shell 1. A placement bin 5 driven by the lifting assembly 4 and adapted to the disposable syringe 2 is slidably connected inside the columnar shell 1. A pressing assembly 6 symmetrically distributed on the inner top wall of the placement bin 5 and tightly fitted to the top of the medicine bottle 12 is provided. The top of the storage bin 5 is provided with a circular hole 7 which is connected to the inside and adapted to the disposable syringe 2. A fixing plate 8 is fixedly connected to the inside of the cylindrical shell 1. A fixing groove 9 adapted to the disposable syringe 2 is provided on the front side of the fixing plate 8. A pull-up assembly 10 which is rotatably connected to the top of the fixing plate 8 is provided on the top wall of the inner cavity of the cylindrical shell 1. A pull-up plate 11 adapted to the disposable syringe 2 is threadedly connected to the outer side of the pull-up assembly 10. A control panel 13 which is electrically connected to both the lifting assembly 4 and the pulling assembly 10 is provided on the top of the cylindrical shell 1.

[0027] The lifting assembly 4 includes a first stepper motor 401, a first gear 402, a first threaded rod 403 and a second gear 404. The bottom wall of the inner cavity of the columnar shell 1 is provided with a first stepper motor 401, and the output end of the first stepper motor 401 is fixedly connected to the first gear 402. The bottom wall of the inner cavity of the columnar shell 1 is rotatably connected to the first threaded rod 403 which is symmetrically distributed and rotatably connected to the bottom of the partition plate 3. The outer sides of the first threaded rod 403 are fixedly connected to the second gear 404 which meshes with the first gear 402. The outer sides of the first threaded rod 403 are threadedly connected to the same placement bin 5. The first stepper motor 401 is electrically connected to the control panel 13.

[0028] When the control panel 13 makes the first stepper motor 401 rotate, the first stepper motor 401 drives the second gear 404 to rotate through the first gear 402, and then drives the first threaded rod 403 to rotate synchronously. The force generated by the rotation of the outer thread of the first threaded rod 403 drives the placement bin 5 to move upward, so that the medicine bottle 12 can be moved upward so that the needle of the disposable syringe 2 enters the medicine bottle 12 and contacts the medicine.

[0029] The clamping assembly 6 includes a clamping spring 601 and a spherical clamping block 602. The top wall of the inner cavity of the placement bin 5 is slidably connected to the spherical clamping block 602 which is symmetrically distributed on the left and right sides. The top of each of the spherical clamping blocks 602 is fixedly connected to a clamping spring 601 which is fixedly connected to the placement bin 5. Each of the spherical clamping blocks 602 is tightly fitted to the top of the medicine bottle 12.

[0030] The medicine bottle 12 is loaded into the storage bin 5. At the same time, the elastic force of the compression spring 601 makes the bottom of the spherical compression block 602 fit tightly with the top of the medicine bottle 12, so that the medicine bottle 12 can be compressed in the storage bin 5.

[0031] A rubber pad 14 adapted to the disposable syringe 2 is fixedly connected to the bottom of the fixing groove 9;

[0032] When the finger hook portion of the disposable syringe 2 enters the fixing groove 9, the friction force of the rubber pad 14 itself and the elastic force generated by the extrusion deformation can ensure the stability of the disposable syringe 2 when extracting the sample;

[0033] The pull-up assembly 10 includes a second stepper motor 101, a third gear 102, a second threaded rod 103 and a fourth gear 104. The inner cavity top wall of the columnar housing 1 is provided with a second stepper motor 101, and the output end of the second stepper motor 101 is fixedly connected to the third gear 102. The inner cavity top wall of the columnar housing 1 is rotatably connected to the second threaded rod 103 which is symmetrically distributed and rotatably connected to the top of the fixed plate 8. The outer sides of the second threaded rod 103 are fixedly connected to the fourth gear 104 meshing with the third gear 102. The outer sides of the second threaded rod 103 are threadedly connected to the same pull-up plate 11. The second stepper motor 101 is electrically connected to the control panel 13.

[0034] When the control panel 13 rotates the second stepper motor 101, the second stepper motor 101 drives the fourth gear 104 to rotate through the third gear 102, and then the second threaded rod 103 rotates synchronously. The force generated by the rotation of the threads on the outer side of the second threaded rod 103 drives the pull-up plate 11 to move upward, thereby driving the piston shaft of the disposable syringe 2 to move upward, thereby achieving the effect of sucking the medicine in the medicine bottle 12 into the disposable syringe 2.

[0035] Working principle:

[0036] Step 1: Load the medicine bottle 12 into the placement bin 5. At the same time, the elastic force of the compression spring 601 makes the bottom of the spherical compression block 602 fit tightly with the top of the medicine bottle 12, so that the medicine bottle 12 can be pressed tightly into the placement bin 5. Load the disposable syringe 2 into the device, so that the finger hook part of the disposable syringe 2 enters the fixed groove 9. When the finger hook part of the disposable syringe 2 enters the fixed groove 9, the friction force of the rubber pad 14 itself and the elastic force generated by the extrusion deformation can ensure the stability of the disposable syringe 2 when extracting the sample, and at the same time make the piston shaft of the disposable syringe 2 stuck in the front side of the pull-up plate 11;

[0037] Step 2: Input the required sampling dose on the control panel 13, and then the control panel 13 rotates the first stepper motor 401, the first stepper motor 401 drives the second gear 404 to rotate through the first gear 402, and then drives the first threaded rod 403 to rotate synchronously, and the force generated by the rotation of the outer thread of the first threaded rod 403 drives the placement bin 5 to move upward, so that the medicine bottle 12 can be moved upward to make the needle of the disposable syringe 2 enter the medicine bottle 12 and contact the medicine;

[0038] Step 3: The control panel 13 causes the second stepper motor 101 to rotate, and the second stepper motor 101 drives the fourth gear 104 to rotate through the third gear 102, thereby causing the second threaded rod 103 to rotate synchronously. The force generated by the rotation of the threads on the outer side of the second threaded rod 103 drives the pull-up plate 11 to move upward, thereby driving the piston shaft of the disposable syringe 2 to move upward, thereby achieving the effect of absorbing the medicine in the medicine bottle 12 into the disposable syringe 2, until the medicine entering the disposable syringe 2 reaches the required sampling dose, the control panel 13 stops the second stepper motor 101, and then the control panel 13 causes the first stepper motor 401 to drive the placement bin 5 to reset, thereby separating the needle of the disposable syringe 2 from the medicine bottle 12, and finally taking out the disposable syringe 2 containing the sampled medicine from the device, and transporting the sampled medicine in the disposable syringe 2 to the analysis equipment for inspection and analysis.
