A near-infrared sampling device for solid pharmaceutical products

Abstract

This utility model relates to the technical field of solid drug sample testing devices; and discloses a near-infrared sample testing device for solid drugs, including a base plate, a rotating structure at the top inner end of the base plate, and a clamping structure at the bottom inner end of the base plate; the rotating structure includes a rotating groove, which is located at the top inner end of the base plate. This utility model allows the operating rod to rotate inside the rotating groove. When the pulling force is greater than the spring force, the inner wall of the positioning groove abuts against the inclined surface of the locking block and forces the locking block to move into the groove until it returns to a suitable position. This cancels the positioning effect of the locking block on the set of placement frames. After rotating a suitable distance, another set of positioning grooves corresponds to the locking block. Under the elastic action of the spring, the locking block can be ejected and locked into the interior of the positioning groove.

Description

Technical Field

[0001] This utility model relates to the technical field of solid drug sample measuring devices; more specifically, it relates to a near-infrared sample measuring device for solid drugs. Background Technology

[0002] Near-infrared (NIR) spectrometers are used for rapid, non-destructive component analysis and quality control of solid dosage form pharmaceuticals using near-infrared spectroscopy. They can be used for quality monitoring during pharmaceutical production to ensure the stability and efficacy of the drugs. These devices typically include a near-infrared spectrometer, a sample preparation system, and data processing software. They can measure the content of key components in pharmaceuticals, identify counterfeit drugs, and assess the physical properties of the drugs.

[0003] Near-infrared spectroscopy is a spectroscopic technique that utilizes the optical properties of organic chemicals in the near-infrared spectral region to rapidly determine the chemical composition of substances. It is currently widely used in pharmaceutical testing due to its advantages of speed, accuracy, and non-destructive operation. When using near-infrared spectroscopy to detect solid pharmaceutical preparations, the first step is to acquire the spectrum of the drug.

[0004] Currently, existing near-infrared sampling devices for solid dosage forms require placing the solid dosage form in a tray before starting the device for sampling. This sampling method typically only allows for sampling one type of solid dosage form. When sampling multiple types of solid dosage forms, multiple repetitions are required, making the operation cumbersome and affecting sampling efficiency, thus reducing the practicality of the device. Furthermore, since most sampling trays are placed on the infrared sampling device, operators may accidentally touch the tray or shake the device during sampling, causing the tray to fall and affecting the effectiveness of the device. Therefore, there is an urgent need for a near-infrared sampling device for solid dosage forms to solve these problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a near-infrared sampling device for solid dosage pharmaceuticals to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a near-infrared sampling device for solid dosage form pharmaceuticals, comprising:

[0007] The base plate has a rotating structure at its inner top and a clamping structure at its inner bottom. The rotating structure includes a rotating groove located at the inner top of the base plate. The clamping structure includes a movable groove located at the inner bottom of the base plate.

[0008] Preferably, the rotating structure further includes a rotating circular plate, which is inserted into the rotating groove. A positioning groove is provided on one side of the rotating circular plate, and six sets of positioning grooves are provided. An operating rod is fixedly connected to one side of the outer surface of the rotating circular plate, and one end of the operating rod passes through and extends out of the rotating groove. A placement plate is fixedly connected to the top of the rotating circular plate, and the bottom surface of the placement plate is in contact with the top surface of the base plate. A placement frame is fixedly connected to the top surface of the placement plate, and six sets of placement frames are provided. A groove is provided inside the base plate on one side of the rotating groove, and a spring is fixedly connected inside the groove. One end of the spring is provided with a locking block. This design allows the placement plate to rotate inside the base plate.

[0009] Preferably, the positions of the six sets of rotating discs correspond to the positions of the six sets of placement frames. This design allows the position of the rotating discs to be determined by observing the position of the placement frames.

[0010] Preferably, one end of the spring is fixedly connected to a limiting circular plate, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the groove. This design makes the movement of the locking block more stable.

[0011] Preferably, both sides of the outer surface of the card block are inclined, and the external dimensions of the card block are adapted to the internal dimensions of the positioning groove. This design ensures that the rotating disc is not obstructed by the card block when it rotates inside the rotating groove.

[0012] Preferably, the clamping structure further includes a lead screw, which is connected to the internal bearing of the movable groove. One end of the lead screw passes through and extends out of the interior of the movable groove, and movable blocks are threaded to the outer surfaces of both ends of the lead screw. A clamping plate is fixedly connected to the bottom end of the movable block. This design can position the base plate in a suitable position of the sample measuring device.

[0013] Preferably, the outer surface threads at both ends of the lead screw are designed to be opposite to each other, and the internal threads of the two sets of movable blocks fitted on the outer surface of the lead screw are designed to be opposite to each other. This design allows the two sets of movable blocks to move synchronously inward and outward along the outer surface of the lead screw.

[0014] The technical effects and advantages of this utility model are as follows: By pulling the operating rod to rotate inside the rotating groove, when the pulling force is greater than the elastic force of the spring, the inner wall of the positioning groove can be made to abut against the inclined surface of the locking block and press the locking block to move into the groove until the locking block moves back to the appropriate position. After the locking block moves back to the appropriate position, the positioning effect of the locking block on the set of placement frames can be canceled. After rotating a suitable distance, when another set of positioning grooves and the locking block are in the corresponding position, the locking block can be popped out and locked into the interior of the set of positioning grooves under the elastic action of the spring itself. This design allows the testing equipment to quickly adjust the position of the six sets of placement frames after testing the solid drug in one set of placement frames, so that the other placement frames stop in the appropriate position in sequence for testing. This makes the testing equipment no longer need to repeat the process multiple times when testing various types of solid drugs, making the operation more convenient and improving the testing efficiency, thus improving the practicality of the equipment to a certain extent.

[0015] By rotating the lead screw, the two sets of movable blocks move inward synchronously along the outer surface of the lead screw, causing the clamping plates at the bottom to move accordingly until the two sets of clamping plates abut against the bearing plate on the testing equipment, thus positioning the base plate. This design ensures that the base plate is stably fixed on the testing equipment, preventing it from tipping over due to accidental contact by staff during the testing process. This maintains the stability of the base plate during use, improving the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The solid drug testing device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1, as Figures 1-4 As shown, this embodiment proposes a near-infrared sampling device for solid dosage form pharmaceuticals, comprising:

[0024] The base plate 1 has a rotating structure 2 at its top interior and a clamping structure 3 at its bottom interior.

[0025] The rotating structure 2 includes a rotating groove 21, which is located at the top of the interior of the base plate 1. The rotating structure 2 also includes a rotating circular plate 22, which is inserted into the rotating groove 21. A positioning groove 23 is provided on one side of the interior of the rotating circular plate 22, and six sets of positioning grooves 23 are provided. An operating rod 24 is fixedly connected to one side of the outer surface of the rotating circular plate 22, and one end of the operating rod 24 passes through and extends out of the interior of the rotating groove 21. A placement plate 25 is fixedly connected to the top of the rotating circular plate 22, and the bottom surface of the placement plate 25 is in contact with the top surface of the base plate 1. The top surface of the plate 25 is fixedly connected to a placement frame 26, and there are six sets of placement frames 26. The bottom plate 1 has a groove 27 on one side of the rotating groove 21, and a spring 28 is fixedly connected inside the groove 27. One end of the spring 28 is provided with a locking block 29. Under the elastic action of the spring 28 itself, the locking block 29 can be locked into the corresponding positioning groove 23 to position the plate 25 after rotation. This allows the plate 25 to remain unchanged when measuring the solid medicine inside a certain set of placement frames 26, making it convenient for staff to perform the measurement operation.

[0026] The positions of the six sets of rotating circular plates 22 correspond to the positions of the six sets of placement frames 26. With this design, after the placement plate 25 rotates, the position of the rotating circular plate 22 can be determined by observing the position of the placement frame 26, which makes it convenient for staff to operate it.

[0027] One end of the spring 28 is fixedly connected to a limiting circular plate, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the groove 27. This design can limit the position of the locking block 29, prevent the locking block 29 from falling out of the groove 27, and keep the locking block 29 stable and horizontally moving, so that it can be accurately locked into the corresponding positioning groove 23.

[0028] Both sides of the outer surface of the locking block 29 are inclined, and the external dimensions of the locking block 29 are adapted to the internal dimensions of the positioning groove 23. This design allows the inner wall of the positioning groove 23 to move along the inclined surface of the locking block 29 and press it, so that the locking block 29 moves back into the interior of the groove 27, thereby facilitating the rotation of the rotating disc 22.

[0029] Example 2, as Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0030] The clamping structure 3 includes a movable groove 31, which is located at the bottom of the base plate 1. The clamping structure 3 also includes a lead screw 32, which is connected to the bearing inside the movable groove 31. One end of the lead screw 32 passes through and extends out of the interior of the movable groove 31. Movable blocks 33 are threaded to the outer surfaces of both ends of the lead screw 32. A clamping plate 34 is fixedly connected to the bottom of the movable block 33. This design can clamp and position the base plate 1 when it is placed inside the measuring device, so that the base plate 1 remains unchanged during use and is not easy to fall off.

[0031] The threads on the outer surfaces of the two ends of the lead screw 32 are designed to be opposite to each other, and the internal threads of the two sets of movable blocks 33 fitted on the outer surface of the lead screw 32 are designed to be opposite to each other. With the design of the opposite threads at both ends of the lead screw 32, the two sets of movable blocks 33 can move inward or outward synchronously, and drive the clamping plate 34 to move accordingly to achieve the clamping effect.

[0032] In this application, the lead screw 32 and all movable parts require regular cleaning and maintenance (including but not limited to dust removal and lubrication).

[0033] Working principle: When using the equipment, first place the various solid pharmaceutical products to be tested into the six sets of placement frames 26, then pick up the base plate 1 neatly and place it in the appropriate position of the testing device. Rotate the screw 32 so that the two sets of movable blocks 33 move inward synchronously along the outer surface of the screw 32, and drive the clamping plate 34 at the bottom to move accordingly until the two sets of clamping plates 34 abut against the carrier plate on the testing device, thus positioning the base plate 1. This design can connect the base plate 1 with the testing device, keeping it stable during the testing process and preventing the risk of it falling. After the base plate 1 is used, rotate the screw 32 in the opposite direction so that the two sets of movable blocks 33 move outward synchronously. At this time, the two sets of clamping plates 34 will move away from the carrier plate, thus canceling the positioning effect of the base plate 1. At this time, it is convenient for the staff to remove it and wipe and clean the inside of the multiple sets of placement frames 26 and the outer surface of the base plate 1 to ensure a clean and tidy result.

[0034] When using the equipment, first start the sampling device to sample the solid dosage form inside a set of placement frames 26. After the sampling of this set of solid dosage form is completed, the operating rod 24 can be pulled to rotate inside the rotating groove 21. When the pulling force is greater than the elastic force of the spring 28, the inner wall of the positioning groove 23 can be made to abut against the inclined surface of the locking block 29 and press the locking block 29 to move into the groove 27 until the locking block 29 moves back to the appropriate position. Then the positioning effect of the locking block 29 on the rotating circular plate 22 can be canceled. At this time, the rotating circular plate 22 can be easily rotated as a whole. After the rotating circular plate 22 has rotated a suitable distance, the other set of positioning grooves 23 will be in the corresponding position with the locking block 29. Under the elastic action of the spring 28, the locking block 29 can be ejected and locked into the interior of the positioning groove 23. At this time, the position of the rotating disc 22 after rotation can be positioned. After the solid drug sample in one set of placement frames 26 is tested, the operating rod 24 can be rotated to move another set of placement frames 26 to the testing area. The operator can then operate the testing equipment to test it. By repeating the above operation, the solid drug samples in the six sets of placement frames 26 can be tested in sequence. This allows the operator to quickly test six types of solid drugs at a time, improving the efficiency of the testing work. The above is the complete working principle of this utility model.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
