Description

Technical Field

[0001] This invention relates to the field of pharmaceutical liquid detection devices, and more specifically, to a pharmaceutical liquid detection device for the production of traditional Chinese medicine injections. Background Technology

[0002] Traditional Chinese medicine injections are sterile preparations made from Chinese medicinal herbs through extraction and purification processes, intended for injection into the human body. They revolutionize the traditional method of drug administration, allowing the medicine to directly enter the bloodstream and exert its effects rapidly. Characterized by rapid onset of action and high bioavailability, they play a vital role in the clinical treatment of some acute, severe, and complex diseases.

[0003] Ampoules are a common packaging form for traditional Chinese medicine (TCM) injections. During the production process, impurities and foreign objects may be present in the ampoule solution. If these issues are not detected and addressed promptly, they can seriously affect patient safety. Therefore, rigorous testing of the ampoule solution is an indispensable part of TCM injection production. Traditional solution testing devices often use image detection technology to determine the presence of impurities inside the ampoule. However, in practice, the system sometimes misjudges products that are perfectly fine as containing impurities, resulting in false positives. Discarding such products directly would lead to a waste of drug resources. On the other hand, if a product is changed from unqualified to qualified based on a single, simple re-inspection, this practice may lack rigor in the re-inspection process, failing to completely eliminate doubts and potentially affecting drug quality and patient safety. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a detection device for the drug solution in the production of traditional Chinese medicine injections.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid medicine detection device, comprising a control unit, a frame, a fixed circular plate, a rotating annular plate surrounding the fixed circular plate, a top annular plate fixedly connected to the rotating annular plate via a support rod, a rotary drive device for driving the rotating annular plate to rotate, a turning unit, two detection units, and two material transfer units; the rotating annular plate has multiple placement positions, each placement position having a circular through hole and a U-shaped limiting protrusion, the bottom end of the circular through hole is fixed with a mounting crossbar, the mounting crossbar is connected to a first lifting plate via a first electric lifting rod, a first rotating block is installed on the first lifting plate, and above each placement position is a second lifting plate connected to the top annular plate via a second electric lifting rod, a second rotating block is installed on the second lifting plate, both the first and second rotating blocks having the capability to be... An insertion groove is inserted into the top of the ampoule; the detection unit includes a starting part, an emergency stop part, a light source part, and an image acquisition part. The starting part includes a first mounting frame, a first translation seat connected to the first mounting frame via a first electric push rod, a first motor mounted on the first translation seat, and a drive wheel mounted on the first motor that can abut against a second rotating block to rotate the second rotating block. The emergency stop part includes a second mounting frame, a second translation seat connected to the second mounting frame via a second electric push rod, and an abutment block mounted on the second translation seat that can abut against the second rotating block to stop the second rotating block from rotating. The material transfer unit can grasp and invert the ampoule; the fixed circular plate has an installation groove; the turning unit includes a second motor installed in the installation groove and a rotating seat driven by the second motor. The rotating seat has two placement grooves for placing ampoules.

[0006] Furthermore, the transfer unit can remove an ampoule from one placement position and place it in another empty placement position.

[0007] Furthermore, the transfer unit can remove an ampoule from one placement position and place it in the placement groove of the rotating seat; the transfer unit can also remove an ampoule from the placement groove of the rotating seat and place it in an empty placement position.

[0008] Furthermore, the first mounting bracket is fixed with a first guide rod, and the first translation seat has a first guide hole that mates with the first guide rod.

[0009] This makes the movement of the first translation seat more stable.

[0010] Furthermore, the second mounting bracket is fixed with a second guide rod, and the second translation seat has a second guide hole that mates with the second guide rod.

[0011] This makes the movement of the second translation seat more stable.

[0012] Furthermore, in the detection unit, the image acquisition unit is used to acquire images of the ampoule that is abutted by the abutting block.

[0013] Furthermore, the first lifting plate and the first rotating block are connected by a first bearing.

[0014] Thus, the first rotating block can rotate rapidly relative to the first lifting plate.

[0015] Furthermore, the second lifting plate and the second rotating block are connected by a second bearing.

[0016] Thus, the second rotating block can rotate rapidly relative to the second lifting plate.

[0017] Furthermore, each placement position can hold one ampoule to be tested.

[0018] Furthermore, the first and second mounting brackets of the detection unit are both connected to the frame, the light source is fixed to the fixed circular plate, and the image acquisition unit is fixed to the frame; the fixed circular plate is connected to the frame.

[0019] Furthermore, a gear ring is fixed at the rotating annular plate, and a third motor is installed at the fixed circular plate, the third motor driving a drive gear that meshes with the gear ring.

[0020] This allows the rotating ring plate to rotate.

[0021] Furthermore, the third motor is mounted on a motor mount connected to the fixed circular plate.

[0022] Furthermore, the fixed circular plate has an annular groove, and the rotating annular plate has a slider that cooperates with the annular groove.

[0023] In some embodiments, the fixed circular plate and the rotating annular plate are connected by a bearing unit.

[0024] Further, the material transfer unit includes a translation mechanism, a third translation seat driven by the translation mechanism, a fourth motor mounted on the third translation seat, a third mounting bracket connected to the fourth motor, a third electric push rod mounted on the third mounting bracket, a fourth mounting bracket connected to the third electric push rod, a third electric lifting rod mounted on the fourth mounting bracket, a fifth mounting bracket connected to the third electric lifting rod, a fifth motor mounted on the fifth mounting bracket, a sixth mounting bracket connected to the fifth motor, a finger cylinder mounted on the sixth mounting bracket, and two clamping blocks connected to the finger cylinder; the translation mechanism includes a first end plate, a second end plate, a slide rail, a sixth motor mounted on the first end plate, a lead screw bearing mounted on the second end plate, and a lead screw connecting the sixth motor and the lead screw bearing; the third translation seat has a threaded hole that mates with the lead screw and a slide groove that mates with the slide rail.

[0025] Furthermore, it also includes a loading and unloading unit, a waste collection container, and two pushing units.

[0026] Further, the loading and unloading unit includes a support plate with two strip-shaped mounting holes. Guide and limiting plates are installed on both sides of the strip-shaped mounting holes. Conveyor belt units are installed in the strip-shaped mounting holes, and the two conveyor belt units are a loading conveyor belt unit and a unloading conveyor belt unit, respectively. The pushing unit includes a mounting base, an electric telescopic rod installed on the mounting base, and a pushing block connected to the electric telescopic rod. The two pushing units are a first pushing unit and a second pushing unit, respectively. The position of the rotating annular plate facing the loading conveyor belt unit is the loading position, the position facing the unloading conveyor belt unit is the unloading position, and the position facing the waste collection container is the waste placement position. The loading position, unloading position, and waste placement position are three adjacent positions. The first pushing unit is used to push the ampoules in the waste placement position to the waste collection container, and the second pushing unit is used to push the ampoules in the unloading position to the unloading conveyor belt unit.

[0027] Because the annular rotating plate is rotating, the positions of the loading position, unloading position, and waste placement position on the annular rotating plate are not fixed. However, the loading position always faces the loading conveyor unit, the waste placement position always faces the waste collection container, and the unloading position always faces the unloading conveyor unit.

[0028] Furthermore, the detection unit can perform detection operations on the ampoule, including using a starting unit to rotate the ampoule, using an emergency stop unit to stop the rotation of the ampoule, and using an image acquisition unit to acquire an image of the ampoule.

[0029] By rotating and suddenly stopping the ampoule, impurities that are attached to the walls or settled at the bottom can be stirred up and captured by the image acquisition unit.

[0030] Furthermore, the two detection units are the first detection unit and the second detection unit, respectively; the two material transfer units are the first material transfer unit and the second material transfer unit, respectively.

[0031] Furthermore, the second detection unit is located downstream of the first detection unit.

[0032] Furthermore, the drug solution detection device is capable of performing the following detection steps:

[0033] 1) The ampoule is inspected by the first detection unit. The image from the first detection unit is used to determine whether it is qualified. If it is qualified, the ampoule is pushed from the feeding position to the feeding conveyor unit. If it is unqualified, proceed to step 2).

[0034] 2) The first transfer unit picks up the ampoules that the first detection unit has determined to be unqualified and flips them 180 degrees to achieve inversion;

[0035] 3) Use the first transfer unit to place the ampoule from step 2) back to its original position;

[0036] 4) The inverted ampoule is inspected using the second detection unit. The image from the second detection unit is used to determine whether it is qualified. If it is not qualified, the ampoule is pushed from the waste placement position to the waste collection container. If it is qualified, proceed to step 5).

[0037] 5) Use the second transfer unit to pick up the inverted ampoule, rotate it 180 degrees again to make it upright, and place it in one of the placement grooves of the rotating seat; use the first transfer unit to pick up an ampoule that has been inspected and determined to be qualified by the first detection unit, and place it in the other placement groove of the rotating seat.

[0038] 6) Rotate the rotating seat 180 degrees, and use the first transfer unit to place the ampoule that has been inverted and tested back to the original position of the ampoule that has been tested and determined to be qualified by the first testing unit; use the second transfer unit to place the ampoule that has been tested and determined to be qualified by the first testing unit back to the original position of the ampoule that has been inverted and tested.

[0039] 7) The second detection unit is used to detect the ampoules that have been inverted. If the detection is qualified, the ampoule is then pushed to the unloading conveyor unit at the unloading placement position. If the detection is unqualified, the ampoule is then pushed to the waste collection container at the waste placement position.

[0040] Furthermore, it also includes a third pushing unit and a collection container to be confirmed. The third pushing unit includes a mounting base, an electric telescopic rod mounted on the mounting base, and a pushing block connected to the electric telescopic rod. One of the multiple placement positions is a placement position to be confirmed facing the third pushing unit. The third pushing unit is capable of pushing the ampoule in the placement position to be confirmed into the collection container to be confirmed.

[0041] Furthermore, if a new ampoule fails the initial inspection before the re-inspection of an ampoule is completed, this ampoule will be directly identified as an ampoule to be confirmed, and then pushed into the collection container to be confirmed by the third feeding unit.

[0042] Therefore, since the newly discovered ampoules that failed the initial inspection cannot be re-inspected (the parts required for the re-inspection are being used), they are pushed into the collection container for confirmation, so that they can be manually inspected again later.

[0043] Beneficial effects:

[0044] 1. The liquid detection device of this application can perform re-inspection on ampoules that have passed the initial inspection. The re-inspection is divided into inverted inspection and upright inspection. Only when both the inverted and upright inspections of the re-inspection are passed can the ampoules be judged as qualified.

[0045] 2. The drug liquid detection device of this application achieves re-inspection by setting up two transfer units and changing the placement of the ampoule, without the need for additional complex re-inspection mechanisms. The optimization of the process makes the detection device more concise overall. Attached Figure Description

The two detection units are the first detection unit and the second detection unit; the two transfer units are the first transfer unit and the second transfer unit.

[0069] Working Principle: The liquid medicine detection device of this application is implemented through the following method, as shown in the figure. The rotating annular plate can rotate, and can rotate one section at a time, rotating the angle of two adjacent placement positions each time. The feeding conveyor unit can transport ampoules to the placement positions. When the ampoule moves to the placement position, both the first and second electric lifting rods can extend, so that the bottom of the ampoule is abutted by the first rotating block, and the top of the ampoule is abutted by the second rotating block. Furthermore, since both the first and second rotating blocks have insertion grooves, the ampoule can also be clamped between the first and second rotating blocks when it is inverted. The detection process for each ampoule is as follows: First, the ampoule is detected by the first detection unit. If the detection is qualified, when the ampoule rotates with the rotating annular plate to the unloading placement position, it is pushed to the unloading conveyor unit by the second pushing unit. If the first detection unit fails the detection, a re-inspection is performed. The re-inspection process involves using a second detection unit to test the inverted ampoules. If the ampoule fails the test, it is deemed unqualified and subsequently pushed to the waste collection container. If the ampoule passes the test, the first detection unit is used again to test the upright ampoules. If the ampoule fails the test, it is deemed unqualified and subsequently pushed to the waste collection container. If the ampoule passes the test, it is deemed qualified and subsequently pushed to the unloading conveyor unit.

[0070] The specific testing steps are as follows:

[0071] 1) The ampoule (referred to as the first ampoule for ease of description) is detected by the first detection unit (e.g., Figure 1 As shown), the first ampoule is pushed from the feeding position to the feeding conveyor unit when it is qualified based on the image of the first detection unit. If it is qualified, the first ampoule is pushed to the feeding conveyor unit. If it is unqualified, proceed to step 2.

[0072] 2) The first ampoule is grasped and flipped 180 degrees using the first transfer unit to achieve inversion (e.g., Figure 3-5 (as shown);

[0073] 3) Use the first transfer unit to place the first ampoule back into its original position (e.g., ...). Figure 7 (As shown); that is, after the first transfer unit picks up and inverts the first ampoule, it quickly moves it downstream and waits there (this waiting allows the liquid level inside the ampoule to remain calm, which is more conducive to subsequent testing. During this waiting period, the ampoules in the other placement positions at the annular plate can be tested normally by the first detection unit) until the original placement position of the first ampoule (which is now empty) is rotated to the current position of the first transfer unit, and the inverted first ampoule is placed into the empty placement position.

[0074] 4) Use the second detection unit to detect the inverted first ampoule (e.g.) Figure 9 As shown), the image from the second detection unit is used to determine whether the sample is qualified. If it is not qualified, the first ampoule is pushed from the waste placement position to the waste collection container. If it is qualified, proceed to step 5.

[0075] 5) Using the second transfer unit, pick up the inverted first ampoule, rotate it 180 degrees to make it upright, and place it in one of the placement grooves of the rotating seat; using the first transfer unit, pick up an ampoule that has been inspected and determined to be qualified by the first inspection unit (for convenience, it is referred to as the second ampoule; the second ampoule has been determined to be qualified and does not need to be re-inspected, and will be pushed to the unloading conveyor unit later), and place it in the other placement groove of the rotating seat (e.g., Figure 11 (as shown);

[0076] 6) Rotate the rotating seat 180 degrees (the purpose of rotating 180 degrees is to make it easier for the first and second transfer units to pick up the corresponding ampoules), use the first transfer unit to place the first ampoule in the original position of the second ampoule; use the second transfer unit to place the second ampoule in the position of the first ampoule;

[0077] 7) Use the second detection unit to test the first ampoule (e.g., Figure 13As shown, when the inspection is qualified, the first ampoule bottle is subsequently pushed to the blanking conveyor belt unit at the blanking placement position; when the inspection is unqualified, the first ampoule bottle is subsequently pushed to the waste collection container at the waste placement position.

[0078] Therefore, the ampoule bottles that pass the initial inspection are directly judged as qualified, and the ampoule bottles that fail the initial inspection are subject to a re-inspection. When both inspections during the re-inspection are qualified, they are judged as qualified; otherwise, they are judged as unqualified. Thus, by adding a re-inspection that includes two inspections, it avoids both false positives caused by the initial inspection (i.e., actually qualified but judged as unqualified during the initial inspection) and missed detections caused by a simple re-inspection (i.e., actually unqualified but not detected during the re-inspection).

[0079] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
