Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a refrigeration system. Background Art

[0002] In the field of medical device industry, relevant policies and laws require that blood specimens should be processed as soon as possible after collection and stored at a specified temperature of 2-8°C. At present, if relevant testing experiments cannot be carried out immediately after blood specimens are collected, the common practice is to place the blood specimens in a refrigerator (or freezer) and store them at a temperature of 2-8°C. When the specimens need to be tested, they are manually taken out of the refrigerator (or freezer) for testing. If the blood specimen assembly line operation is required, ordinary refrigerators (or freezers) cannot realize automatic storage and retrieval, which obviously cannot meet the requirements. With the development of science and technology, automated refrigeration systems are gradually being introduced to the market, but the following problems are common: (1) limited storage capacity, which cannot fully adapt to the storage of large quantities of sample tubes; (2) low degree of automation, time-consuming and labor-intensive specimen processing, and low efficiency; (3) the volume of the refrigerated area is too large and requires a large space. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a refrigeration system.

[0004] The present invention is achieved through the following technical solutions:

[0005] A refrigeration system includes an operating platform component, a transfer platform component and a refrigeration body, wherein the refrigeration body is provided with a plurality of storage channels, and the refrigeration body is also provided with a transfer platform, wherein the transfer platform has the freedom of movement in the Y direction and the Z direction. When the collected samples need to be refrigerated and stored, a test tube carrier loaded with sample test tubes is manually placed on the operating platform component, and is transferred to the transfer platform through the transfer platform component, and then the test tube carrier loaded with sample test tubes is transferred to the storage channels of each layer through the transfer platform.

[0006] Furthermore, a handover hatch is provided between the operating platform component and the transfer platform component. When the sample needs to be sent to the cold storage body for storage, the handover hatch is opened, and when there is no sample to be stored, the handover hatch is closed, so as to ensure the safety of the handover process on the operating platform component.

[0007] Furthermore, a first door is provided between the transfer platform assembly and the cold storage body. When the sample needs to be stored in the cold storage, the first door is opened to realize the handover of the sample between the transfer platform assembly and the transfer and delivery platform. When the sample enters the cold storage body and there is no sample to be stored in the outside, the first door is closed to prevent the cold air inside the body from flowing out, thereby reducing energy consumption.

[0008] Furthermore, the operation platform assembly is provided with a handover conveyor, and the test tube carrier loaded with sample test tubes to be stored is manually placed on the handover conveyor and transferred to the transfer platform assembly via the handover conveyor.

[0009] Furthermore, a transfer platform is provided on the transfer platform assembly. The test tube carrier to be stored is transferred to the transfer platform via the handover platform, and a test tube counting module is also provided on the transfer platform for counting the number of stored samples.

[0010] Furthermore, a receiving and conveying platform is provided in the cold storage body at a position close to the first storage body door, and a positioning baffle is provided on the side of the receiving and conveying platform away from the first storage body door.

[0011] Furthermore, the handover conveyor, transfer conveyor, receiving conveyor, transport conveyor, and storage channel all have forward and reverse conveying functions. The test tube carriers to be stored pass through the handover conveyor, transfer conveyor, receiving conveyor, and transport conveyor in sequence, and finally enter the storage channel for storage. The test tube carriers that need to be returned to the operating platform assembly can also be sent back to the handover conveyor through the reverse conveying function.

[0012] The test tube carriers to be stored are transferred from the transfer conveyor table to the receiving conveyor table, and then from the receiving conveyor table to the transfer conveyor table. Since the transfer conveyor table has the freedom of movement in the Y and Z directions and has a forward conveying function, and the storage channel also has a forward conveying function, the test tube carriers can be transported to the storage channels on each layer for storage. When it is necessary to transfer the test tube carriers on the lower storage channel to the upper layer, the test tube carriers are transferred to the transfer conveyor table through the reverse function of the storage channel. The transfer conveyor table moves upward in the Z direction and drives the test tube carrier to move against the positioning baffle on the receiving conveyor table through the Y-direction freedom movement and its own reverse conveying function. The positioning baffle blocks the test tube carrier to achieve the positioning of the test tube carrier on the transfer conveyor table. This positioning method is accurate, simple and practical in structure, and has low process difficulty.

[0013] Furthermore, the storage channel includes a storage conveyor platform and a turnover conveyor platform. The storage conveyor platform is used to store the test tube carriers put into the warehouse, and the turnover conveyor platform is used to temporarily store the test tube carriers when the test tube carriers need to be dispatched.

[0014] Furthermore, it also includes a robotic arm and an image recognition module.

[0015] Furthermore, each layer of the storage channel includes a plurality of storage conveying tables and turnover conveying tables, and each storage conveying table and turnover conveying table can hold a plurality of test tube racks.

[0016] Furthermore, the image recognition module includes a recognition device, a test tube cup and a transfer test tube rack, wherein the transfer test tube rack is provided with a plurality of test tube slots, and the number of test tube slots on the transfer test tube rack is not less than the number of test tube slots on the test tube carrier. When it is necessary to identify the information of the sample test tube in the test tube carrier, the robot grabs the sample test tube into the test tube cup, and after the information identification is completed by the recognition device, the robot grabs the sample test tube from the test tube cup to the transfer test tube rack, and when the information identification of all sample test tubes on the current target test tube carrier is completed, the robot, under the control of the control system, classifies the sample test tubes of the same sample information according to the information of the identified sample test tubes and places them in the centralized area of ​​the target test tube carrier, and after the classification and placement is completed, the transfer conveyor table transfers the target test tube carrier to the original storage conveyor table, wherein the same sample information includes sample type (whole blood, serum, plasma), test items, etc.

[0017] Furthermore, the identification device includes a barcode identifier and a camera. The barcode identifier is used to identify the barcode information on the sample test tube, and the camera is used to photograph the sample test tube. The control system analyzes the sample quality based on the photos taken by the camera, and for unqualified samples (such as samples that have been centrifuged, samples with clots, insufficient sample volume, etc.), they are classified and placed in the centralized area of ​​the target test tube carrier according to the above steps.

[0018] Furthermore, it also includes a sample transfer mechanism with forward and reverse conveying functions, and a second storage door is provided on the side of the cold storage body opposite to the first storage door. When the cold storage system is applied to a laboratory assembly line processing system, when the sample tubes on the storage and conveying table need to be post-processed (such as centrifugation, biochemical testing, etc.), the sample tubes can be transferred to the post-processing process module through the forward conveying function of the sample transfer mechanism, and at the same time, the processed sample tubes can be transferred back to the cold storage body through the reverse transmission function of the sample transfer mechanism.

[0019] Furthermore, a rotating conveyor platform is also provided on the transfer platform assembly, and the rotating conveyor platform is located between the handover conveyor platform and the transfer conveyor platform, and the rotating conveyor platform has forward and reverse conveying functions, and the rotating conveyor platform has a rotational freedom of not less than 90°, and a recycling bucket is provided below the rotating conveyor platform. When the sample test tubes on the test tube carrier on the storage conveyor platform have completed the relevant project detection and are empty test tubes, the test tube carrier is transported to the rotating conveyor platform through the reverse conveying function of the storage conveyor platform, the temporary storage of the turnover conveyor platform (if necessary), the Z-direction and Y-direction freedom movement functions of the transfer conveyor platform and its own reverse transportation function, the reverse conveying function of the receiving conveyor platform, and the reverse conveying function of the transfer conveyor platform. Then, after the rotating conveyor platform rotates 90° clockwise or counterclockwise, the test tube carrier falls into the recycling bucket through the forward or reverse conveying function of the rotating conveyor platform.

[0020] When the test tube carrier on the storage conveyor table contains unqualified sample test tubes, the test tube carrier is transported to the handover conveyor table through the reverse conveying function of the storage conveyor table, the temporary storage of the turnover conveyor table (when necessary), the Z- and Y-direction freedom movement functions of the transfer conveyor table and its own reverse transport function, the reverse conveying function of the receiving conveyor table, the reverse conveying function of the transfer conveyor table, and the reverse transport function of the rotating conveyor table, and then manually processed.

[0021] Furthermore, an emergency exit is provided on the side of the cold storage body, an emergency door is provided on the emergency exit, a drawer-type push-pull structure matching the number, shape and size of the storage channels is provided in the cold storage body, the storage channels are all provided on the drawer-type push-pull structure, and the drawer-type push-pull structure can be moved to the inside or outside of the cold storage body through the emergency exit. When the refrigeration system has a related failure and cannot be automatically transmitted, or when the relevant samples need to be urgently taken out or placed in the cold storage body, the operator can open the emergency door, pull the drawer-type push-pull structure to the outside of the cold storage body, and the storage channels on it are pulled to the outside of the cold storage body, and then manually take out or put the relevant sample tubes into the cold storage body. After taking and placing, the drawer-type push-pull structure is pushed to the inside of the cold storage body.

[0022] Combined with the structural characteristics of the present invention, compared with the prior art, the refrigeration system provided by the present invention has the following beneficial effects:

[0023] (1) In the limited space of the cold storage, a large number of specimens can be stored in the cold storage through the design of a three-dimensional (multi-layer) storage channel, which effectively solves the problem of large-capacity refrigeration in existing cold storage. In addition, the sample tubes on the negative layer storage transfer table can be dispatched through the setting of a turnover transfer table in the storage channel.

[0024] (2) Through the effective docking of each conveyor platform, the specimens can be quickly handed over to the cold storage for storage, shortening the long waiting time of the handover personnel and improving the handover rate. Through the forward and reverse conveying functions of each conveyor platform, the test tube rack can move in two directions on the conveyor platform, effectively realizing the transmission of refrigerated samples between the inside and outside of the cold storage.

[0025] (3) The specimens can be sorted and classified by means of the robotic arms, transfer test tube racks, image recognition modules, turnover conveyor tables, and transfer conveyor tables that are reasonably arranged inside the cold storage, making it easier to quickly and accurately obtain specimens during experiments.

[0048] It should be noted that the refrigeration system described in the present invention realizes automatic control of each process through a control system. The control system is not within the scope of protection of the present invention and will not be described in detail herein.

[0049] like Figures 1 to 5As shown, the refrigeration system of the present invention has the following working process:

[0050] 1. Storage of sample test tubes:

[0051] The staff collects samples through sample test tubes. When the collected samples need to be refrigerated, the staff manually places the sample test tubes on the test tube carrier 10, and places the test tube carrier 10 to be stored on the handover and transfer table 8 of the operating platform assembly 1. The handover hatch 6 is opened, and then the samples are transferred to the transfer and transfer table 9 through the handover and transfer table, and then the handover hatch 6 is closed to ensure the safety of the manual handover process on the operating platform assembly. In this embodiment, the handover hatch 6 is opened and closed in the horizontal direction. Of course, it can also be opened and closed in the vertical direction. Closed, all fall within the protection scope of the present invention. In addition, a test tube counting module 11 is also provided on the transfer conveyor table 9. When the test tube carrier 10 passes through the transfer conveyor table 9, the test tube counting module 11 counts the sample test tubes loaded on the test tube carrier 10. Then, the first warehouse hatch 7 is opened, and the test tube carrier 10 is transferred to the receiving conveyor table 14 through the transfer conveyor table 9. Then, the first warehouse hatch 7 is closed to prevent the cold air inside the warehouse from flowing out to reduce energy consumption. Then, the test tube carrier 10 is transferred from the receiving conveyor table 14 to the transfer conveyor table 5.

[0052] In this embodiment, the storage channel 4 in the cold storage body includes three layers, namely the negative second layer, the negative first layer and the first layer (the negative second layer is the lowest layer and the first layer is the highest layer). Each layer of the storage channel 4 includes three storage and conveying platforms 401 and one turnover conveying platform 402. Each storage and conveying platform and the turnover conveying platform can hold four test tube carriers. When the test tube carriers to be stored are transferred to the transfer conveying platform 5, since the transfer conveying platform 5 has the freedom of movement in the Y and Z directions, the test tube carriers to be stored can be transported to the position of the corresponding storage and conveying platform 401. Then, the test tube carriers are transported to the storage and conveying platforms of each layer through the forward conveying function of the transfer conveying platform 5 and the storage and conveying platform 401. During the implementation process, the test tube carriers to be stored can be stored in the storage and conveying platforms of each layer in the order from bottom to top, from left to right, or from bottom to top, from right to left, or from top to bottom, from left to right, or from top to bottom, from right to left.

[0053] 2. Information identification of sample test tubes:

[0054] (1) Information identification of sample tubes on the first-level storage conveyor:

[0055] The test tube carrier on which the sample test tubes to be identified are located is called the target test tube carrier. The robot arm 16 grabs the sample test tubes on the target test tube carrier one by one and puts them into the image recognition module 17 for information identification. Then, the robot arm 16 grabs the sample test tubes with completed information from the image recognition module 17 and returns them to the target test tube carrier.

[0056] (2) Information identification of sample tubes on the storage and transfer tables on the second and first negative floors:

[0057] Since each storage conveyor table can hold four test tube carriers, when the target test tube carrier is located at the outermost side of the storage conveyor table (it should be noted that the outermost side of the storage conveyor table referred to in this article refers to the test tube carrier on the storage conveyor table that is closest to the transfer conveyor table), the transfer conveyor table moves to the position of the storage conveyor table where the target test tube carrier is located based on its Y-direction and Z-direction movement freedom, and transfers the target test tube carrier from the storage conveyor table 401 to the transfer conveyor table 5 through the reverse conveying function of the storage conveyor table 401 and the transfer conveyor table 5. The transfer conveyor table 5 moves to the position of the receiving conveyor table 14 based on its Y-direction and Z-direction movement freedom, and is set on the receiving conveyor table 14. There is a positioning baffle 15. When the transfer conveyor 5 moves to the position of the receiving conveyor 14, the target test tube carrier on the transfer conveyor 5 is abutted against the positioning baffle 15 on the receiving conveyor to realize the positioning of the test tube carrier. Subsequently, the robot arm 16 grabs the sample test tubes on the target test tube carrier one by one and puts them into the image recognition module 17 for information recognition. Then, the robot arm 16 grabs the sample test tubes with completed information from the image recognition module 17 one by one and puts them back into the target test tube carrier on the transfer conveyor. Through the Y- and Z-direction freedom of movement of the transfer conveyor, and the forward conveying function of the transfer conveyor and the storage conveyor, the target test tube carrier is transferred back to the corresponding storage conveyor.

[0058] When the target test tube carrier is located on the inner side of the storage conveyor platform (it should be noted that the inner side of the storage conveyor platform referred to in this article refers to the side away from the transfer conveyor platform, that is, the test tube carriers on the inner side except the outermost test tube carrier), the test tube carriers (hereinafter referred to as the obstacle test tube carriers) blocking the outer side of the target test tube carrier are transferred to the transfer conveyor platform through the reverse conveying function of the storage conveyor platform 401 and the transfer conveyor platform 5, and the obstacle test tube carriers are transferred one by one to the turnover conveyor platform 402 on the same layer for temporary storage through the transfer conveyor platform, and then, in the same step as above, the target test tube carrier is transferred to the transfer conveyor platform 5 through the reverse conveying function of the storage conveyor platform 401 and the transfer conveyor platform 5, and the transfer conveyor platform Based on its Y-direction and Z-direction movement freedom, the table 5 moves to the position of the receiving conveying table 14, and the target test tube carrier on the transfer conveying table 5 is abutted against the positioning baffle 15 on the receiving conveying table 14 to realize the positioning of the test tube carrier. Subsequently, the robot arm 16 grabs the sample test tubes on the target test tube carrier one by one and puts them into the image recognition module 17 for information recognition. Then, the robot arm 16 grabs the sample test tubes with completed information from the image recognition module 17 one by one and puts them back into the target test tube carrier on the transfer conveying table. Through the Y-direction and Z-direction movement freedom of the transfer conveying table, as well as the forward conveying function of the transfer conveying table 5 and the storage conveying table 401, the target test tube carrier is transferred back to the corresponding storage conveying table.

[0059] In the above embodiment, the test tube carriers entering the warehouse are first stored in the storage conveyor, and then the sample test tube information is identified. In another embodiment, the information identification of the sample test tube can also be realized before the test tube carrier is transferred to the storage conveyor for storage, that is, when the test tube carrier is transferred from the receiving conveyor 14 to the transfer conveyor 5, the robot arm 16 grabs the sample test tube on the transfer conveyor 5 into the image recognition module 17 for information identification, and then grabs it back to the test tube carrier on the transfer conveyor 5, and then transfers it to the storage conveyor 401 through the transfer conveyor 5 for storage, that is, the information identification of the sample test tube is completed first, and then it is stored in the storage conveyor, which also falls within the protection scope of the present invention.

[0060] 3. Classification of samples:

[0061] When information identification is performed on the sample test tubes in the target test tube carrier, the robot arm 16 grabs the sample test tubes into the test tube cup 1702, and then the identification device 1701 performs information identification on them. The robot arm 16 grabs the sample test tubes for which information identification has been completed into the transfer test tube rack 1703. Since the number of test tube slots on the transfer test tube rack 1703 is not less than the number of test tube slots on the test tube carrier, after the information identification of all sample test tubes on the current target test tube carrier is completed, all sample test tubes on the target test tube carrier are transferred to the transfer test tube rack 1703. Under the control of the control system, the robot arm 16 classifies the sample test tubes with the same sample information and places them in a centralized area of ​​the target test tube carrier according to the information of the identified sample test tubes. After the classification and placement is completed, the transfer conveyor table 5 transfers the target test tube carrier to the original storage conveyor table, wherein the same sample information includes sample type (whole blood, serum, plasma), test items, etc.

[0062] In this embodiment, the recognition device 1701 in the image recognition module 17 includes a barcode recognizer for recognizing the barcode information on the sample test tube, and a camera for taking photos of the sample test tube. The camera feeds back the taken photo information to the control system, and the control system analyzes the sample quality through the taken photo information. For unqualified samples (for example, the sample has been centrifuged, the sample has clots, the sample volume is insufficient, etc.), they are also classified and placed in a concentrated area of ​​the target test tube carrier according to the above steps.

[0063] 4. Samples are transferred to the processing module:

[0064] In this embodiment, a sample transfer mechanism 18 with forward and reverse transmission functions is also included. A second storage door 19 is provided on the side of the cold storage body opposite to the first storage door 7. The cold storage system can be applied to a laboratory assembly line processing system. When the sample test tubes on the storage and conveying table need to be post-processed (such as centrifugation, biochemical testing and other post-processing processes):

[0065] The sample tubes on the first-layer storage and conveying table are directly grabbed by the robot arm 16 and placed in the sample transfer mechanism 18. Then, the sample transfer mechanism 18 passes through the second storage body door 19. The forward conveying function of the sample transfer mechanism 18 transfers the sample tubes to the post-processing process module. At the same time, the reverse transmission function of the sample transfer mechanism 18 can be used to transfer the post-processed sample tubes back to the cold storage body, and the robot arm 16 grabs them and returns them to the corresponding tube carriers on the storage and conveying table for storage.

[0066] For the sample test tubes on the negative second and negative first storage and conveying tables, similar to the above-mentioned steps for information identification of the sample test tubes on the negative second and negative first storage and conveying tables, when the target test tube carrier is located at the outermost side of the storage and conveying table 401, the transfer conveying table 5 moves to the position of the storage and conveying table where the target test tube carrier is located based on its Y-direction and Z-direction degrees of freedom of movement, and transfers the target test tube carrier from the storage and conveying table 401 to the transfer conveying table 5 through the reverse conveying function of the storage and conveying table 401 and the transfer conveying table 5. The transfer conveying table 5 moves to the receiving conveying table 14 based on its Y-direction and Z-direction degrees of freedom of movement. At the position of the receiving and conveying platform 14, a positioning baffle 15 is arranged on the receiving and conveying platform 14. When the transfer and conveying platform 5 moves to the position of the receiving and conveying platform 14, the target test tube carrier on the transfer and conveying platform 5 abuts against the positioning baffle 15 on the receiving and conveying platform 14 to realize the positioning of the test tube carrier. Subsequently, the robot arm 16 grabs the sample test tubes on the target test tube carrier one by one to the sample transfer mechanism 18, and then the sample transfer mechanism 18 passes through the second warehouse hatch 19, and the sample transfer mechanism 18 transfers the sample test tube to the post-processing process module through the forward conveying function of the sample transfer mechanism 18. When the robot arm 16 grabs the sample test tubes on the target test tube carrier that need to be transferred to the post-processing process module, After the sample test tubes are sequenced, the transfer conveyor platform transfers the target test tube carrier back to the corresponding storage conveyor platform; when the target test tube carrier is located on the inner side of the storage conveyor platform, the storage conveyor platform 401 and the transfer conveyor platform 5 are used to transfer the obstacle test tube carrier to the transfer conveyor platform 5, and the transfer conveyor platform 5 transfers the obstacle test tube carriers one by one to the turnover conveyor platform 402 on the same layer for temporary storage, and then, in the same step, the storage conveyor platform 401 and the turnover conveyor platform 402 are used to transfer the target test tube carrier to the transfer conveyor platform 5. The transfer conveyor platform 5 can move based on its Y and Z degrees of freedom of movement. The robot arm 16 moves to the position of the receiving and conveying platform 14, and the target test tube carrier on the transfer and conveying platform abuts against the positioning baffle 15 on the receiving and conveying platform 14 to realize the positioning of the test tube carrier. Subsequently, the robot arm 16 grabs the sample test tubes on the target test tube carrier one by one to the sample transfer mechanism 18, and then the sample transfer mechanism 18 passes through the second warehouse hatch 19, and through the forward conveying function of the sample transfer mechanism 18, the sample test tubes are transferred to the post-processing process module. After the robot arm 16 grabs the sample test tubes on the target test tube carrier that need to be transferred to the post-processing process, the transfer and conveying platform transfers the target test tube carrier back to the corresponding storage and conveying platform.

[0067] 5. Recovery of sample tubes:
