Description

Technical Field

[0001] The utility model relates to a sample testing device, in particular to a solid medicine near-infrared sample testing device, belonging to the technical field of rapid drug testing. Background Art

[0002] Most commonly used solid medicines are in the form of tablets or blocks. The common characteristics of solid medicines are that compared with liquid medicines, they have good physical and chemical stability, low production costs, and are easy to take and carry. The pretreatment of the preparation process undergoes the same unit operations to ensure uniform mixing and accurate dosage of the drugs. As for the component content of solid medicines, it is necessary to use near-infrared technology for sampling and analysis. Near-infrared spectroscopy is a spectral technology that uses the optical properties of organic chemicals in the near-infrared spectral region to rapidly determine the chemical composition of substances. It has been widely used in the field of drug testing and has the advantages of being fast, accurate, and non-destructive.

[0003] In the prior art, a near-infrared sampling device for solid dosage drugs disclosed in announcement number CN214539241U includes a frame, guide rails are fixedly installed on the left and right inner walls of the frame, sliders are arranged in the guide rails, a pressure plate is fixedly installed between two groups of the sliders, recesses are opened on the left, middle and right sides of the pressure plate, an airbag is placed in the recess, and the upper end surface of the airbag is bonded to the pressure plate by glue, and a locking hole is opened on the bottom wall of the frame near the lower side of the airbag. By providing a spring and a guide rail, the pressure plate can be moved upward, and the tablets to be tested can be placed on the positioning holes respectively. The spring tension gives the pressure plate a force, and the airbag of the pressure plate squeezes the tablets. The prior art uses the airbag to clamp and fix the solid medicine, and then performs sample analysis on the solid medicine. However, in actual use, although the prior device can easily clamp the solid medicine, it is necessary to remove the solid medicine after the sample is tested. The prior art also needs to restore the pressure plate to its initial state and then take out the solid medicines one by one, which cannot achieve fast and convenient placement of the solid medicine, which is time-consuming and labor-intensive. Secondly, when performing sample analysis on the solid medicine, the solid medicine can be analyzed by performing sample analysis at multiple positions, that is, the sample probe is aimed at different sides of the medicine for near-infrared irradiation, so as to perform more accurate sample analysis on the solid medicine. However, the prior device cannot perform appropriate orientation adjustment on the fixed solid medicine, that is, only one side of the solid medicine can be subjected to near-infrared irradiation sample analysis at a time, which also greatly affects the efficiency of sample analysis.

[0034] Embodiment 2

[0035] Improvements based on Example 1:

[0036] like Figures 1 to 7As shown, a probe light-transmitting hole 11 is provided at the upper end of the sample testing housing 1, and the probe end of the near-infrared instrument probe 2 is aligned with the probe light-transmitting hole 11, and the probe light-transmitting hole 11 is provided just above the medicine card cavity 41, and a reciprocating slide rail 13 is embedded in the bottom surface of the medicine feeding seat placement cavity 12 provided in the sample testing housing 1, and a fixed card slot 35 is provided at the tail bottom end of the square medicine feeding seat 3, and the slider of the reciprocating slide rail 13 is clamped in the fixed card slot 35, so that the near-infrared light emitted by the near-infrared instrument probe 2 can pass through the probe light-transmitting hole 11, and then can be aligned with the solid medicine below for sample testing and analysis, and the square medicine feeding seat 3 is driven to move for positioning through the movement of the slider on the reciprocating slide rail 13, so that solid medicines at different positions can be aligned just below the probe light-transmitting hole 11.

[0038] Furthermore, a positioning arrow 34 is provided on the front end face of the square medicine inlet seat 3, and positioning sharp teeth 51 are symmetrically provided on the column body of the rotating column 5, and the tip of the positioning arrow 34 points in a direction corresponding to one of the positioning sharp teeth 51, so as to ensure that when the rotating column 5 is rotated, when the other positioning sharp tooth 51 of the rotating column 5 corresponds to the tip of the positioning arrow 34, it indicates that the columnar medicine holder 4 has achieved a 180° flip, that is, the positioning arrow 34 can correspond to the positioning sharp tooth 51 to ensure the accuracy of the rotation position each time it is flipped.

[0039] Furthermore, a liquid conducting cavity 42 and a plurality of push rod movable cavities 43 are also provided in the columnar drug holder 4, and the plurality of push rod movable cavities 43 are all connected to the liquid conducting cavity 42. The hydraulic clamping assembly includes an airbag 45, a push rod 46 and a piston 47. One end of the push rod 46 is connected to the piston 47. The piston 47 and one end of the push rod 46 are movably arranged in the push rod movable cavity 43. A compression spring 48 is sleeved on the rod of the push rod 46 located in the push rod movable cavity 43. One end of the push rod 46 located outside the push rod movable cavity 43 is fixedly connected to the airbag 45. Airbag placement grooves 44 are provided on the inner walls of both sides of the drug holding cavity 41, and the airbag 45 is placed in the airbag placement grooves 44. The liquid conducting cavity 42 is filled with hydraulic oil. When pressure is applied to the hydraulic oil in the liquid guiding cavity 42, the piston 47 can be pushed by the action of the hydraulic oil, and then the push rod 46 can push the air bags 45 on both sides of the medicine-carding cavity 41 to move toward each other, so as to form a clamping action for the placed solid medicine, and when clamping the solid medicine, the air bags 45 can be deformed to ensure that a larger clamping surface can be formed for solid medicines of different sizes to ensure the firmness of the clamping, and when the pressure applied to the hydraulic oil in the liquid guiding cavity 42 is removed, the push rod 46 can be restored to its initial state through the provided compression spring 48, that is, the clamped solid medicine can be loosened so that the solid medicine can fall directly from the medicine-carding cavity 41.

[0040] Furthermore, a liquid storage chamber 53 is opened in the rotating column 5, the liquid storage chamber 53 is connected with the liquid guiding chamber 42, and the liquid storage chamber 53 is filled with hydraulic oil. A push plate 54 is movably arranged in the liquid storage chamber 53, and a threaded push rod 52 is threadedly engaged with the rotating column 5, and one end of the threaded push rod 52 located in the liquid storage chamber 53 is coaxially fixedly connected with the push plate 54, and the push plate 54 can be driven to move in the liquid storage chamber 53 by twisting the threaded push rod 52, and then the hydraulic oil in the liquid storage chamber 53 can be pressurized by the push plate 54, and the hydraulic oil in the liquid storage chamber 53 is connected with the hydraulic oil in the liquid guiding chamber 42, that is, it can form a pressure on the hydraulic oil in the liquid guiding chamber 42, so as to push the hydraulic clamping assembly.

[0041] like Figure 1 , Figure 8 and Fig. 9As shown, a number of parallel limiting slots 6 are provided in the columnar medicine holder 4 and the rotating column 5. The limiting slots 6 are symmetrically arranged on the upper and lower sides of the installation position of the hydraulic clamping component, and a medicine support plate 7 is movably inserted in the limiting slots 6. When solid medicine needs to be clamped, the medicine support plate 7 can be first inserted in the limiting slots 6 below the hydraulic clamping component to enable the solid medicine to be placed on the support plate, thereby facilitating the hydraulic clamping component to clamp the solid medicine. The medicine support plate 7 can be inserted into the limiting slots 6 at a suitable position according to the particle size of the solid medicine to ensure that the hydraulic clamping component can clamp in the middle of both sides of the solid medicine. After the solid medicine is clamped and fixed, the medicine support plate 7 can be pulled out to make the solid medicine suspended. After the columnar medicine holder 4 is flipped over, the other side of the solid medicine can be exposed to facilitate sample analysis and also facilitate the falling of the solid medicine.

[0042] Furthermore, a plurality of medicine grooves 71 are provided on the upper and lower side plates of the medicine support plate 7, and the medicine grooves 71 are respectively arranged in a one-to-one correspondence with the medicine card inner cavity 41. When the medicine is placed in the medicine card inner cavity 41, the solid medicine will be supported by the medicine support plate 7, and because the medicine grooves 71 are arranged in a one-to-one correspondence with the medicine card inner cavity 41, the solid medicine can be limitedly placed in the medicine grooves 71 before being clamped and fixed, that is, a preliminary limit positioning of the solid medicine can be formed to facilitate clamping.

[0043] Working principle: According to the particle size of the solid medicine, the medicine support plate 7 is selected to be inserted into the limiting slot 6 at the appropriate position. When the medicine is placed in the medicine card cavity 41, the solid medicine will be supported by the medicine support plate 7 and can be limited to be placed in the medicine groove 71. The push plate 54 is driven to move in the liquid storage cavity 53 by twisting the threaded push rod 52, and then the hydraulic oil in the liquid storage cavity 53 can be pressurized by the push plate 54. The hydraulic oil in the liquid storage cavity 53 is connected with the hydraulic oil in the liquid guide cavity 42, that is, it can form pressure on the hydraulic oil in the liquid guide cavity 42, and the piston 47 is pushed by the action of the hydraulic oil, and then the push rod 46 can push the airbags 45 on both sides of the medicine card cavity 41 to move toward each other, so as to form a clamping action for the placed solid medicine, and when the solid medicine is clamped, the airbag 45 can be deformed to To ensure that a larger clamping surface can be formed for solid medicines of different sizes, the firmness of the clamping is ensured. When the square medicine feeder seat 3 is pushed into the sample testing housing 1, the near-infrared instrument probe 2 can perform near-infrared sample analysis on one side of the solid medicine. When the square medicine feeder seat 3 is completely pushed into the sample testing housing 1, the columnar medicine holder 4 is rotated to flip the solid medicine. Then, during the withdrawal process of the square medicine feeder seat 3, the other side of the solid medicine can be subjected to near-infrared sample analysis. That is, sample analysis on different sides of the solid medicine can be performed, thereby improving the accuracy of the sample analysis. There is no need to manually flip the solid medicine, thereby greatly improving the sample testing efficiency. After the sample testing is completed, the solid medicine can be directly dropped from the through slot 31 provided on the lower end surface of the square medicine feeder seat 3, so that the solid medicine after the sample testing can be easily taken out.
