Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and particularly to a pharmaceutical experiment sample extractor. Background Art

[0002] Pharmacy is a healthcare industry that connects health science and chemical science. It undertakes the responsibility of ensuring the safe and effective use of drugs. Its main task is to continuously provide more effective drugs and improve drug quality to ensure medication safety. In pharmaceutical research, we need to conduct various experiments to study the pharmaceutical principles of drugs. Usually, before conducting pharmaceutical experiments, we need to extract samples. During the medical learning process, in order to understand the drug properties, pharmaceutical experiments are required. In the experiments, a sample extractor is needed to extract a quantitative drug sample for research. Currently, the sample extractors on the market include syringe samplers, automatic samplers, and manual samplers.

[0003] Among them, the syringe sampler is particularly widely used on the market. For example, the "pharmaceutical experiment sample extractor" provided by the Chinese patent authorization announcement number CN221464969U. By operating the sample extractor with this device, the operation risk caused by hand-held operation can be avoided. The electric push rod expands and contracts to drive the piston rod of the sample extractor to move up and down to achieve accurate sampling and dosing. After use, loosen the bolt to remove the sample extractor for cleaning and disinfection. After the cleaning and disinfection are completed, insert the sampler into the inner part of the limit tube and tighten the bolt to fix the sample extractor.

[0004] Although the above patent realizes accurate sampling and dosing, it is difficult to guarantee the purity of the extracted liquid medicine. Before extracting the liquid medicine, the experimenter needs to spend time filtering the liquid medicine before sampling, which is relatively cumbersome. Or in some experiments, for the sake of saving time, simple filtering is carried out, so that there are still some medicinal fiber debris remaining in the liquid medicine. As a result, the liquid medicine sampled by the sample extractor is mixed with impurities, which is likely to be affected during subsequent experiments.

[0005] To meet this market demand, a new type of pharmaceutical experiment sample extractor needs to be designed. This sample extractor combines modern mechanical design and electronic technology, and through innovative sampling, filtering, collection, and discharge mechanisms, it realizes the efficient extraction of mixed liquid medicine and impurity separation. Summary of the Invention

An annular electromagnet is fixed at the edge of the top of the movable plate. A liquid extraction head is fixedly penetrated through the edge of the movable plate. The liquid extraction head penetrates through the fixing plate and the transparent cylinder through a hose and is connected to the air pipe connector. A limiting ring is further fixed at the edge of the bottom of the movable plate. A circuit integration board is fixed on the inner side wall of the transparent cylinder above the fixing plate. The circuit integration board is electrically connected to the annular electromagnet and the micro electric push rod, and a conducting wire connected to the circuit integration board penetrates through the transparent cylinder and is connected with a wire connector.

[0009] Further, a connection terminal is fixed at the lower front part of the sampling device main body and is electrically connected to the control button, and the connection terminal is plugged and conductively connected to the wire connector.

[0010] Further, the elastic abutting structure includes a plurality of limiting springs fixed inside the installation groove near the periphery of the U-shaped card slot. The other ends of the plurality of limiting springs are fixed with a limiting plate. A U-shaped groove corresponding to the U-shaped card slot is formed in the middle of the limiting plate.

[0011] Further, the control button is electrically connected to the display screen, the micro bidirectional air pump and the storage battery.

[0012] Further, the filtering and collecting structure includes a metal filter plate with round sliders fixed on both opposite sides. The two round sliders are respectively slidably connected in the two sliding grooves to install the metal filter plate inside the transparent cylinder. A plurality of filtering holes are vertically formed through the metal filter plate, and a plurality of intercepting strips are fixedly connected between the filtering holes above and below the metal filter plate.

[0013] Further, the metal filter plate is ferritic stainless steel, and two circular scraping pads are symmetrically fixed above and below the metal filter plate in contact with the inner wall of the transparent cylinder, and the transverse section of the circular scraping pad is trapezoidal.

[0014] Further, a discharge head is fixedly connected to the middle outside of the transparent cylinder.

Relatively clean liquid medicine can be extracted for experiments in the later stage.

[0021] In summary, this device can filter and extract the liquid medicine. When time is tight, the mixed liquid medicine can be directly filtered and extracted through the metal filter plate to obtain clean liquid medicine. When time is relatively loose, the metal filter plate can also be blown to flip to clean the impurities in the liquid medicine, achieving one-time cleaning, which is convenient for extracting relatively clean liquid medicine for experiments in the later stage.

[0032] Example 1, which is given by Figures 1-9 Figures 1-9 A pharmaceutical experiment sampling device includes a sampling device main body 2 and a sampling tube 5. A handle 1 is fixed at the bottom of the sampling device main body 2. A storage battery is arranged inside the handle 1, and control buttons 3 are installed outside the handle 1. A micro bidirectional air pump is installed inside the sampling device main body 2, and a display screen 21 is installed at the top of the sampling device main body 2. A sampling installation cylinder 4 is fixed at the front of the sampling device main body 2. A charging and suction joint 42 is fixed in the middle of the connection between the sampling installation cylinder 4 and the sampling device main body 2. The charging and suction joint 42 penetrates through a hose into the sampling device main body 2 and is connected to the output end of the micro bidirectional air pump. An installation groove 41 is formed on the outside of the sampling installation cylinder 4. A U-shaped card slot 421 is formed in the middle of the front of the sampling installation cylinder 4 and communicates with the installation groove 41. An elastic abutting structure is installed inside the sampling installation cylinder 4 near the U-shaped card slot 421. The upper part of the sampling tube 5 is in through connection with the inside, and a silica gel ring is fixed at the top. A plug joint 51 is fixed and communicated at the bottom of the sampling tube 5. The sampling tube 5 is inserted into the U-shaped card slot 421 through the plug joint 51 and is clamped and limited at the top with the charging and suction joint 42 in cooperation with the elastic abutting structure. A filtering and collecting device 6 is connected to the outside of the sampling installation cylinder 4, and the filtering and collecting device 6 is adapted to the sampling tube 5.

[0033] Specifically, hold the sampling tube 5 and insert it into the sampling installation cylinder 4 through the installation groove 41. The plug joint 51 of the sampling tube 5 passes through the elastic abutting structure and the U-shaped card slot 421 and extends out. Then press the sampling tube 5 to drive the elastic abutting structure to contract, so that the head of the sampling tube 5 can be sleeved into the charging and suction joint 42. Then release the sampling tube 5, and the elastic abutting structure returns to its position to abut and limit the sampling tube 5. Next, install and use the filtering and collecting device 6. By inserting the filtering and collecting device 6 into a container containing a mixed liquid medicine, the user controls the micro bidirectional air pump to perform a suction operation through the control button 3. The sampling tube 5 generates negative pressure to filter and extract the sample of the mixed liquid medicine.

[0034] Wherein, a filter sheet is arranged on the air pipe connecting the charging and suction joint 42 and the output end of the micro bidirectional air pump.

[0035] In this embodiment, the filtering and collecting device 6 includes a transparent cylinder 61 with a threaded groove 611 opened at the top. The external fixed threaded head of the sampling installation cylinder 4 is threadedly connected to the threaded groove 611 of the transparent cylinder 61. An air pipe connector 63 is arranged in the threaded groove 611 and inlaid with a socket joint 51. Sliding grooves 615 are opened on both opposite sides of the lower part inside the transparent cylinder 61. A filtering and collecting structure 65 is slidably connected between the two sliding grooves 615. A fixing plate 614 is fixed to the upper part inside the transparent cylinder 61. A micro electric push rod 68 is fixed to the middle of the top of the fixing plate 614. The output shaft of the micro electric push rod 68 penetrates through the fixing plate 614 and is fixedly connected with a movable plate 612. An annular electromagnet 66 is fixed to the top edge of the movable plate 612. A liquid extraction head 631 is fixedly penetrated through the edge of the movable plate 612. The liquid extraction head 631 is connected to the air pipe connector 63 through a hose penetrating through the fixing plate 614 and the transparent cylinder 61. A limiting ring 613 is also fixed to the bottom edge of the movable plate 612. A circuit integration board 67 is fixed to the inner side wall of the transparent cylinder 61 above the fixing plate 614. The circuit integration board 67 is electrically connected to the annular electromagnet 66 and the micro electric push rod 68, and the connecting wire of the circuit integration board 67 penetrates through the transparent cylinder 61 and is connected with a wire connector 64.

[0036] Specifically, hold the transparent cylinder 61. First, socket and fix the air pipe connector 63 with the socket joint 51, then threadedly connect and install it through the threaded groove 611 and the threaded head of the sampling installation cylinder 4. Finally, insert the wire connector 64 into the connection terminal 22 to energize. Hold the handle 1 of the sampler main body 2 and insert the transparent cylinder 61 into the vessel containing the mixed liquid medicine. The lower part of the transparent cylinder 61 is immersed in the mixed liquid medicine. The mixed liquid medicine is filtered by the filtering and collecting structure 65. The liquid medicine enters the inside of the transparent cylinder 61 and contacts the liquid extraction head 631. The user controls the micro bidirectional air pump to perform the suction operation through the control button 3. The sampling pipe 5 generates negative pressure and transmits it to the liquid extraction head 631 to extract the liquid medicine. The liquid medicine flows along the hose through the air pipe connector 63 and enters the sampling pipe 5 for storage. Thus, relatively clean liquid medicine can be extracted. After extraction, stop the micro bidirectional air pump by controlling the button 3. When taking out the liquid medicine, hold the upper part of the transparent cylinder 61 and turn it over to separate it from the sampling installation cylinder 4, and then separate the air pipe connector 63 from the socket joint 51. Press the control button 3 to control the micro bidirectional air pump to perform the inflation operation. Compressed air is input into the sampling pipe 5 to squeeze out the liquid medicine, which falls into the experimental instrument for analysis.

[0037] Among them, a connection terminal 22 is fixed to the front lower part of the sampler main body 2 and is electrically connected to the control button 3, and the connection terminal 22 is in plug-in conductive connection with the wire connector 64.

[0038] Among them, the control button 3 is electrically connected to the display screen 21, the micro bidirectional air pump and the storage battery.

[0039] Among them, the sampling tube 5 is made of transparent glass or transparent plastic, and a scale is provided on the surface to determine the extraction volume through the scale.

[0040] In this embodiment, the elastic abutting structure includes a plurality of limiting springs 432 fixed inside the installation groove 41 near the periphery of the U-shaped card slot 421. The other ends of the plurality of limiting springs 432 are fixed with a limiting plate 43. A U-shaped groove 431 is formed in the middle of the limiting plate 43 corresponding to the U-shaped card slot 421.

[0041] Specifically, the insertion joint 51 of the sampling tube 5 passes through the U-shaped groove 431 of the limiting plate 43, then passes through the U-shaped card slot 421, and then presses the sampling tube 5 to drive the limiting plate 43 to squeeze and contract the plurality of limiting springs 432, so that the head of the sampling tube 5 can be sleeved into the filling and suction joint 42. Then release the sampling tube 5, and the plurality of limiting springs 432 return to abut and limit the sampling tube 5.

[0042] Embodiment 2, on the basis of Embodiment 1, the filtering and collecting structure 65 includes a metal filter plate 651 with round sliders 652 fixed on both opposite sides. The two round sliders 652 are respectively slidably connected in the two sliding grooves 615 to install the metal filter plate 651 inside the transparent cylinder 61. A plurality of filter holes 6511 are formed through the upper and lower parts of the metal filter plate 651, and a plurality of intercepting strips 653 are fixedly connected between the upper and lower parts of the metal filter plate 651 and between the plurality of filter holes 6511.

[0043] Specifically, the metal filter plate 651 separates the liquid medicine and the liquid medicine impurities through the plurality of filter holes 6511 on the metal filter plate 651. Since the metal filter plate 651 is installed in the two sliding grooves 615 through the two round sliders 652, when one side of the metal filter plate 651 is blown and stressed, it turns downward, driving the other side of the metal filter plate 651 to turn upward. Thus, the metal filter plate 651 turns in the transparent cylinder 61, immersing the lower part of the transparent cylinder 61 in the mixed liquid medicine, and making the turned metal filter plate 651 contact the mixed liquid medicine. A plurality of intercepting strips 653 are arranged above and below the metal filter plate 651, and the liquid medicine impurities can be lifted and adsorbed on the surface when turning in the mixed liquid medicine.

[0044] Among them, the metal filter plate 651 is ferritic stainless steel, and two circular scraping pads 654 are symmetrically fixed above and below the metal filter plate 651 to contact the inner wall of the transparent cylinder 61. The transverse section of the circular scraping pad 654 is trapezoidal, and the residual liquid on the inner wall of the transparent cylinder 61 can be scraped off by the trapezoidal transverse section of the circular scraping pad 654.

[0045] Embodiment 3, on the basis of Embodiment 1, a discharge head 62 is fixedly connected to the middle outside of the transparent cylinder 61. A through groove 621 is formed through the outside of the discharge head 62 and communicates with two sliding grooves 615. Elastic limit structures 69 are provided at the communicating parts of the through groove 621 and the two sliding grooves 615. The height of the through groove 621 is greater than the thickness of the filter collection structure 65, and the width of the through groove 621 is greater than the diameter of the filter collection structure 65.

[0046] Specifically, the micro bidirectional air pump is controlled to stop working through the control button 3, and the annular electromagnet 66 is controlled to be energized to generate magnetism. The stopped metal filter plate 651 is attracted upward by the magnetic force. The two round sliders 652 move in the two sliding grooves 615. During the movement, the metal filter plate 651 is adjusted to an inclined state to contact the limit ring 613. Then, the micro electric push rod 68 is controlled to contract through the control button 3, driving the movable plate 612 and the metal filter plate 651 to move upward, so that the metal filter plate 651 moves to the position of the discharge head 62. The two round sliders 652 contact and are limited by the two elastic limit structures 69. At this time, the circular electromagnet is controlled to be powered off and demagnetized through the control button 3. At this time, the metal filter plate 651 is separated from the limit ring 613 and drops. It is intercepted and limited by the conical limit blocks 691 of the two elastic limit structures 69, so that it is located at the through groove 621 of the discharge head 62. The device sampler main body 2 is tilted downward in the direction of the discharge head 62, so that the metal filter plate 651 slides out of the through groove 621 into a new tissue collection container, which is convenient for subsequent cleaning. During later installation, the metal filter plate 651 is inserted into the through groove 621, and then the micro electric push rod 68 is controlled to extend to make the movable plate 612 press downward on the metal filter plate 651, so that it slides downward through the two elastic limit structures 69 to the inner bottom of the transparent cylinder 61.

[0047] In this embodiment, the elastic limit structure 69 includes a groove and a conical limit block 691 formed at the right angle where the through groove 621 communicates with the sliding groove 615. Connecting seats 692 are fixed on both sides of the groove. One end of the conical limit block 691 is fixedly penetrated with a connecting shaft 693, and the conical limit block 691 is rotatably connected between the two connecting seats 692 through the connecting shaft 693. A torsion spring is sleeved outside the connecting shaft 693 and is connected and limited to the conical limit block 691 and the connecting seat 692 at both ends respectively;

[0048] Specifically, the metal filter plate 651 drives the round slider 652 to move upward and contact the conical limit block 691. The conical limit block 691 is forced to turn upward through the connecting shaft 693 to drive the torsion spring to contract and store energy. After the round slider 652 passes through the conical limit block 691, the torsion spring rebounds to make the conical limit block 691 return to its original position.

[0049] Working principle:

[0050] First, grasp the sampling tube 5 and insert it into the sampling installation cylinder 4 through the installation groove 41. The insertion joint 51 of the sampling tube 5 passes through the elastic abutting structure and extends out of the U-shaped card slot 421. Then, press the sampling tube 5 to drive the elastic abutting structure to contract, so that the head of the sampling tube 5 can be sleeved into the charging and suction joint 42. Then release the sampling tube 5, and the elastic abutting structure returns to its position to abut and limit the sampling tube 5;

[0051] Next, install and use the filtering and collecting device 6, that is, grasp the transparent cylinder 61. First, sleeve and fix the trachea connector 63 with the insertion joint 51, and then threadedly connect and install it with the threaded head of the sampling installation cylinder 4 through the thread groove 611. Finally, insert the wire connector 64 into the connection terminal 22 to energize;

[0052] When extracting the liquid medicine: Grasp the handle 1 of the sampler main body 2, insert the transparent cylinder 61 into the vessel containing the mixed liquid medicine. The lower part of the transparent cylinder 61 is immersed in the mixed liquid medicine. The mixed liquid medicine is filtered through the filtering and collecting structure 65, that is, the liquid medicine and the liquid medicine impurities are separated through the multiple filtering holes 6511 on the metal filter plate 651. The liquid medicine enters the inside of the transparent cylinder 61 and contacts the liquid extraction head 631. The user controls the micro bidirectional air pump to perform the suction work through the control button 3. The sampling tube 5 generates negative pressure, which is transmitted to the liquid extraction head 631 to extract the liquid medicine. The liquid medicine flows along the hose through the trachea connector 63 into the sampling tube 5 for storage, and the extraction volume is determined through the scale. Thus, relatively clean liquid medicine can be extracted. After extraction, stop the micro bidirectional air pump by controlling the button 3. When taking out the liquid medicine, grasp the upper part of the transparent cylinder 61 and turn it over to separate it from the sampling installation cylinder 4, and then separate the trachea connector 63 from the insertion joint 51. Press the control button 3 to control the micro bidirectional air pump to perform the inflation work. Compressed air is input into the sampling tube 5 to squeeze out the liquid medicine, which falls into the experimental instrument for analysis;

[0053] When cleaning the liquid medicine impurities for extraction: Grasp the handle 1 of the sampler main body 2, control the micro bidirectional air pump to perform the inflation work through the control button 3. Compressed air is input into the sampling tube 5, and as it is transmitted to the liquid extraction head 631 to blow air, the compressed air blows towards one side of the filtering and collecting structure 65. Since the metal filter plate 651 is installed in the two sliding grooves 615 through the two round sliders 652, one side of the metal filter plate 651 is forced by the blowing air to turn downward, driving the other side of the metal filter plate 651 to turn upward. Thus, the metal filter plate 651 turns in the transparent cylinder 61, immersing the lower part of the transparent cylinder 61 in the mixed liquid medicine, and making the turned metal filter plate 651 contact the mixed liquid medicine. A plurality of intercepting strips 653 are arranged above and below the metal filter plate 651, and the liquid medicine impurities can be lifted and adsorbed on the surface when turning in the mixed liquid medicine. After adsorbing a large amount of liquid medicine impurities, take out the vessel and move it to a new collecting vessel;

[0054] Next, control the micro bidirectional air pump to stop working through the control button 3, and control the ring electromagnet 66 to be energized to generate magnetism. The stopped metal filter plate 651 is adsorbed upward by the magnetic force. The two circular sliders 652 move in the two sliding grooves 615, move through the middle metal filter plate 651 to adjust the inclination state to contact the limit ring 613. Then, control the micro electric push rod 68 to contract through the control button 3, drive the movable plate 612 and the metal filter plate 651 to move upward, so that the metal filter plate 651 moves to the discharge head 62 position, and the two circular sliders 652 contact and are limited by the two elastic limit structures 69;

[0055] At this time, control the circular electromagnet to be powered off and demagnetized through the control button 3. At this time, the metal filter plate 651 is separated from the limit ring 613 and falls. It is intercepted and limited by the conical limit blocks 691 of the two elastic limit structures 69, so that it is located at the through groove 621 of the discharge head 62. Tilt the device sampler main body 2 downward in the direction of the discharge head 62, so that the metal filter plate 651 slides out of the through groove 621 into a new tissue collection container, which is convenient for subsequent cleaning treatment;

[0056] Then hold the handle 1 of the sampler main body 2, insert the sampling installation cylinder 4 into the container filled with the mixed liquid medicine. The lower part of the transparent cylinder 61 is immersed in the mixed liquid medicine. The user controls the micro bidirectional air pump to perform suction work through the control button 3. The sampling pipe 5 generates negative pressure, and the liquid medicine is extracted by the filling suction head 52. The liquid medicine flows along the hose through the air pipe connector 63 and enters the sampling pipe 5 for storage;

[0057] During later installation, insert the metal filter plate 651 from the through groove 621, and then control the micro electric push rod 68 to extend to press the movable plate 612 downward against the metal filter plate 651, so that it slides downward through the two elastic limit structures 69 to the inner bottom of the transparent cylinder 61.
