Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an electronic tag reading and writing device for reagent containers. Background Technology
[0002] Generally, reagent bottles contain two chambers, which may hold the same or different types of reagents. To distinguish between reagent types or batch information, each chamber has a corresponding magnetic barcode, typically affixed to the surface of that chamber facing away from the other, i.e., the two magnetic barcodes are affixed to opposite sides of the reagent bottle. During reagent production, a reading and writing device is needed to write the corresponding information into each magnetic barcode. Because the information in each magnetic barcode is different, manually handling the reagent bottle by hand is prone to errors, writing backwards, or omissions, resulting in low production efficiency.
[0003] A current reading and writing device includes a reader / writer, a reader / writer holder, and a reagent kit holder. The reader / writer is vertically mounted within the reader / writer holder, and the reagent kit holder has grooves that match the shape of the bottom of the reagent kit, allowing the reagent kits to be inserted in the corresponding orientation and position, forming a positional relationship with the reader / writer. However, because this reading and writing device lacks a counting function, if there are missed writes or reads during the reading and writing operations of multiple reagent kits in the same batch, the staff will not notice, leading to errors in production operations. Utility Model Content
[0004] The purpose of this invention is to provide an electronic tag reading and writing device for reagent containers that avoids missed writing and missed reading.
[0005] To achieve the above objectives, this utility model provides an electronic tag reading and writing device for reagent containers, including a base, a reader / writer, a main control module, a counter, and a switch module. The base has an installation slot, and the reader / writer is disposed on one side of the installation slot. The main control module, the reader / writer, and the switch module are connected in series in a preset circuit. The switch module is disposed in the installation slot and can conduct the preset circuit. The counter is connected to the main control module and is used to calculate the number of times the preset circuit is energized, thereby calculating the number of times the reader / writer reads and writes.
[0006] As can be seen from the above scheme, when the reagent container is placed directly into the mounting slot, the reagent container can trigger the switch module to close, making the preset circuit conduct, at which time the reader can perform a read / write operation; when the reagent container leaves the mounting slot, the switch module is opened, making the preset circuit de-energized, preparing for the read / write operation of the next reagent container; the counter is used to calculate the number of times the preset circuit is energized, and the number of times it is energized is related to the number of read / write operations of the reader, so that after all reagent containers in the current batch have completed the read / write operation, the number of reagent containers in the current batch can be compared with the count value of the counter to detect whether there are any missed reads or writes in the read / write operation of the current batch of reagent containers, thus avoiding errors. This utility model also has the advantages of simple structure and convenient operation.
[0007] A further option is to set the switch module on the bottom or wall of the mounting slot. The switch module includes a fixed contact and a moving contact that are set opposite to each other. Both the fixed contact and the moving contact are connected to a preset circuit. The moving contact can move toward the fixed contact and make contact with the fixed contact.
[0008] As can be seen from the above scheme, the reagent container can be placed directly in the mounting slot. The reagent container can force the moving contact to move closer to the fixed contact and make contact with the fixed contact, so that the mold opening module closes.
[0009] A further embodiment is that the electronic tag reader / writer for the reagent container also includes a base tray, which is set in the mounting groove. The base tray has a reagent container placement groove and a clearance hole. The reagent container placement groove includes a first groove and a second groove that are interconnected. The first groove is correspondingly set with the reader / writer. The clearance hole is connected to the reagent container placement groove. The switch module extends into the reagent container placement groove through the clearance hole.
[0010] As can be seen from the above scheme, the reagent container can be placed in the reagent container placement slot of the base tray, which forces the switch module to close.
[0011] A further solution is that the base can rotate around its own axis, so that the first slot is away from the reader, while the second slot is set to correspond to the reader.
[0012] As can be seen from the above scheme, the base can rotate the reagent container on it, making it convenient for the reader to read and write the electronic tags in the two cavities of the reagent container in sequence.
[0013] A further proposed solution is that the base is provided with a first position identification element on the first or second groove, and the first position identification element can rotate with the base; the base is provided with a second position identification element and a third position identification element on both sides of the mounting groove, and the first position identification element can sequentially sense and identify the second and third position identification elements.
[0014] As can be seen from the above scheme, with the above settings, the second position identification element and the third position identification element correspond to the two cavities on the reagent container, respectively. When the first position identification element and the second position identification element are sensed and identified, the reader / writer performs a read / write operation on the electronic tag of one cavity; when the first position identification element and the third position identification element are sensed and identified, the reader / writer performs a read / write operation on the electronic tag of the other cavity. Through the above settings, this utility model can effectively avoid reading and writing errors.
[0015] A further embodiment is that the base is provided with a first position identification element in both the first and second grooves, and both first position identification elements can rotate with the base; the base is provided with a second position identification element on one side of the mounting groove, and the second position identification element can sequentially sense and identify the two first position identification elements.
[0016] As can be seen from the above scheme, with the above settings, when the second position identification element senses and identifies the first position identification element of the first slot, the reader performs a read and write operation on the electronic tag on the first slot; when the second position identification element senses and identifies the first position identification element of the second slot, the reader performs a read and write operation on the electronic tag on the second slot.
[0017] A further option is to provide a protrusion on the outer peripheral wall of the base and a step on the inner peripheral wall of the mounting groove. The step extends circumferentially along the mounting groove, and the protrusion is provided on the step and can slide along the extension direction of the step.
[0018] As can be seen from the above scheme, the above settings facilitate the rotation of the base within the mounting groove.
[0019] A further option is to provide stops at both ends of the step extension direction, with the line connecting the two stops passing through the axis of the mounting groove.
[0020] As can be seen from the above scheme, the above settings make it easy to control the maximum rotation angle of the base to 180°. When the base is rotated into position, the electronic tag of the reagent container on it is exactly aligned with the reader.
[0021] A further option is to fix the base in the mounting groove.
[0022] As can be seen from the above scheme, with the above settings, after the reader reads one of the electronic tags, the staff or robotic arm can pick up the reagent container, rotate it 180°, and put it back into the base tray, so that the reader can read the other electronic tag.
[0023] A further option is to provide a foolproof structure in the reagent container placement slot within the first and / or second slot.
[0024] As can be seen from the above scheme, the above settings facilitate the placement of reagent containers into the reagent container placement slot in a preset direction, ensuring that the placement direction of all reagent containers in a batch is consistent. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0042] See Figures 1 to 4 The electronic tag reading and writing device for reagent containers provided in this embodiment includes a base 1, a reader 2, a main control module 3, a counter 4, and a switch module 5.
[0043] The reader 2 and counter 4 are respectively disposed at both ends of the base 1 along its length. The reader 2 is fixed to the base 1 by a reader pressure plate 21. A mounting slot 11 is provided between the reader 2 and the counter 4 in the base 1, preferably located close to the reader 2. A chamber 12 is provided inside the base 1, with an opening facing the bottom wall of the base 1. The main control module 3 is preferably a main control circuit board, and is disposed within the chamber 12. A base plate 13 is detachably connected to the bottom of the base 1, and the base plate 13 blocks the opening of the chamber 12.
[0044] The main control module 3, reader 2, and switch module 5 are connected in series on the preset circuit. The switch module 5 is located in the mounting slot 11 and can turn the preset circuit on or off. A counter 4 is connected to the main control module 3 and is used to calculate the number of times the preset circuit is energized. The number of times the preset circuit is energized is related to the number of read / write operations performed by the reader 2, thus calculating the total number of read / write operations performed by the reader 2. The counter 4 is preferably an electronic counter.
[0045] Furthermore, the switch module 5 is disposed on the bottom or wall of the mounting slot 11. The switch module 5 is preferably a normally open micro switch. The switch module 5 includes a fixed contact and a moving contact disposed opposite to each other. Both the fixed contact and the moving contact are connected to a preset circuit. The moving contact can move closer to the fixed contact and make contact with the fixed contact. When the moving contact makes contact with the fixed contact, the switch module 5 is closed.
[0046] In the first embodiment, the reagent container 7 can be placed directly in the mounting slot 11. The reagent container 7 can force the switch module 5 to close, thereby turning on the preset circuit. At this time, the reader 2 can perform read and write operations. After the read and write is completed, the reagent container 7 is taken out, the switch module 5 returns to the open state, thereby cutting off the preset circuit. At this time, the reader 2 is not conductive and cannot perform read and write operations.
[0047] In the second embodiment, the electronic tag reader / writer for the reagent container further includes a base tray 6, which is disposed within the mounting groove 11, and the reagent container 7 is placed within the base tray 6. Specifically:
[0048] The base 6 has a reagent container placement slot 61 and a clearance hole 62. The reagent container placement slot 61 includes a first slot 611 and a second slot 612. The first slot 611 and the second slot 612 can be arranged opposite to each other, or they can be arranged adjacent to each other. In this embodiment, the former is preferred, that is, the first slot 611 and the second slot 612 are respectively arranged at both ends of the length direction of the reagent container placement slot 61. The length direction of the reagent container placement slot 61 is parallel to the length direction of the base 1, so that the first slot 611 is correspondingly arranged with the reader 2. The two cavities of the reagent container 7 are respectively corresponding to the first slot 611 and the second slot 612. An electronic tag is affixed to the outer wall of the cavity facing away from the other cavity. The reader 2 first reads and writes the electronic tag above the first slot 611, that is, reads and writes the electronic tag of one cavity of the reagent container 7.
[0049] The clearance hole 62 is preferably disposed on the bottom of the reagent container placement slot 61, and the clearance hole 62 communicates with the reagent container placement slot 61. The switch module 5 is disposed in the chamber 12 of the base 1. The moving contact of the switch module 5 extends into the reagent container placement slot 61 through the clearance hole 62 and protrudes upward from the bottom of the reagent container placement slot 61. When the reagent container 7 is placed into the reagent container placement slot 61, the bottom wall of the reagent container 7 can press the moving contact against the fixed contact, so that the moving contact and the fixed contact make contact, and the switch module 5 closes.
[0050] The base 6 can rotate around its own axis, so that the first groove 611 moves away from the reader 2, while the second groove 612 is correspondingly arranged with the reader 2. The base 6 can be driven to rotate by a rotation drive device or by external force, which is not limited here.
[0051] After the reader 2 finishes reading and writing the electronic tag above the first slot 611, the base 6 drives the reagent container 7 on it to rotate, so that the reader 2 can read and write the electronic tag above the second slot 612, that is, read and write the electronic tag of the other cavity of the reagent container 7.
[0052] In one embodiment, such as Figure 4As shown, to facilitate the identification of the two electronic tags on the reagent container 7, the base 6 is provided with a first position identification element 8a on the first groove 611 or the second groove 612. The first position identification element 8a is preferably located on the bottom wall of the first groove 611 or the second groove 612. The first position identification element 8a can rotate with the base 6. In this embodiment, the first position identification element 8a is located on the bottom wall of the first groove 611. The base 1 is provided with a second position identification element 9a and a third position identification element 10 on both sides of the mounting groove 11. Preferably, the second position identification element 9a and the third position identification element 10 are located on opposite sides of the mounting groove 11, and the second position identification element 9a is located on the side of the mounting groove 11 closer to the reader / writer 2. When the base 6 rotates, the first position identification element 8a can sequentially sense and identify the second position identification element 9a and the third position identification element 10.
[0053] The first position identifier 8a is a magnet, while the second position identifier 9a and the third position identifier 10 are both Hall effect sensors, and each of the second position identifier 9a and the third position identifier 10 has unique identification information. Both the second position identifier 9a and the third position identifier 10 are connected to the main control module 3.
[0054] When the first groove 611 of the base 6 corresponds to the reader 2, the first position identification element 8a and the second position identification element 9a are sensed and identified; when the base 6 is rotated 180°, the second groove 612 of the base 6 corresponds to the reader 2, and at this time the first position identification element 8a and the third position identification element 10 are sensed and identified.
[0055] In another embodiment, such as Figure 5 As shown, to facilitate the identification of the two electronic tags on the reagent container 7, the base 6 is provided with a first position identification element 8b on both the first groove 611 and the second groove 612. Both first position identification elements 8b can rotate with the base 6. A second position identification element 9b is provided on one side of the mounting groove 11, preferably closer to the reader / writer 2. When the base 6 rotates, the second position identification element 9b can sequentially sense and identify the two first position identification elements 8b.
[0056] The first position identification element 8b is a Hall sensor, and both first position identification elements 8b have unique identification information. The first position identification element 8b is connected to the main control module 3. The second position identification element 9b is a magnet.
[0057] When the first groove 611 of the base 6 corresponds to the reader 2, the first position identification element 8b and the second position identification element 9b on the first groove 611 are sensed and identified; when the base 6 is rotated 180°, the second groove 612 of the base 6 corresponds to the reader 2, and at this time the first position identification element 8b and the second position identification element 9b on the second groove 612 are sensed and identified.
[0058] exist Figure 3 In order to limit the rotation angle of the base 6, a protrusion 63 is provided on the outer peripheral wall of the base 6. The protrusion 63 protrudes radially from the outer peripheral wall of the base 6. Axially, the protrusion 63 is located on the upper part of the outer peripheral wall of the base 6. A step portion 111 is provided on the inner peripheral wall of the mounting groove 11. The step portion 111 is recessed radially into the inner peripheral wall of the mounting groove 11 and extends circumferentially along the mounting groove 11. The protrusion 63 is provided on the step portion 111 and can slide along the extending direction of the step portion 111.
[0059] Since the first groove 611 and the second groove 612 of the reagent container placement groove 61 are arranged opposite to each other, the step 111 is designed as a semi-circular structure, and both ends of the step 111 are provided with a stop 1111. The two stops are respectively arranged on opposite sides of the mounting groove 11, and the line connecting the two stops passes through the axis of the mounting groove 11. Preferably, the two stops 1111 are symmetrically arranged about the diameter of the mounting groove 11. When the protrusion 63 slides from one end of the step 111 to the other end, the base 6 rotates exactly 180°.
[0060] The line connecting the two stop portions 1111 can be perpendicular to the line connecting the first groove portion 611 and the second groove portion 612 of the reagent container placement groove 61, or the line connecting the two stop portions 1111 can be parallel to the line connecting the first groove portion 611 and the second groove portion 612 of the reagent container placement groove 61. In this embodiment, the former is preferred.
[0061] After the reader 2 completes the reading and writing operation of the electronic tag on the first slot 611, the staff or robot arm rotates the base 6 and the reagent container 7 on it together by 180° so that the electronic tag on the second slot 612 is directly facing the reader 2. At this time, the reader 2 can perform reading and writing operations on the electronic tag on the second slot 612.
[0062] The sidewall of the protrusion 63 is set as an arc surface, which corresponds to the arc sidewall of the step 111. The arc surface and the sidewall of the step 111 may not contact each other or may contact each other; even if they contact each other, it is a line contact, which helps to reduce the friction between them.
[0063] The bottom wall of the protrusion 63 is set as a plane, and the supporting surface of the step 111 is set as a plane. The bottom wall of the protrusion 63 is set parallel to the supporting surface to ensure that the base 6 can always remain horizontal during rotation.
[0064] After all reagent containers 7 in the current batch have completed the read / write operation, the number of reagent containers 7 in the current batch is compared with the count value of counter 4 to detect whether there are any missed reads or writes in the read / write operation of reagent containers 7 in the current batch. In this embodiment, since the base 6 is rotatable, two read / write operations are required after the reagent container 7 is placed in the base 6, so that the count value of counter 4 is equal to the number of reagent containers 7 in the current batch, and is also equal to 0.5 times the read / write count of reader 2. If the comparison result does not satisfy the condition that the count value of counter 4 is equal to the number of reagent containers 7 in the current batch, or if the comparison result does not satisfy the condition that the count value of counter 4 is equal to 0.5 times the read / write count of reader 2 corresponding to the reagent container 7 in the current batch, it means that an error occurred in the process of reading and writing the electronic tag.
[0065] In the third embodiment, the electronic tag reader / writer for the reagent container also includes a base 6, which is fixedly installed in the mounting groove 11, and the reagent container 7 is placed in the base 6.
[0066] The base 6 has a reagent container placement slot 61 and a clearance hole 62. The reagent container placement slot 61 includes a first slot 611 and a second slot 612. The first slot 611 and the second slot 612 can be arranged opposite to each other or adjacent to each other. In this embodiment, the former is preferred, that is, the first slot 611 and the second slot 612 are respectively arranged at both ends of the length direction of the reagent container placement slot 61. The length direction of the reagent container placement slot 61 is parallel to the length direction of the base 1, so that the first slot 611 is correspondingly arranged with the reader 2. The two cavities of the reagent container 7 are respectively corresponding to the first slot 611 and the second slot 612. An electronic tag is affixed to the outer wall of the cavity facing away from the other cavity. The reader 2 first reads and writes the electronic tag above the first slot 611, that is, reads and writes the electronic tag of one cavity of the reagent container 7.
[0067] The clearance hole 62 is preferably disposed on the bottom of the reagent container placement slot 61, and the clearance hole 62 communicates with the reagent container placement slot 61. The switch module 5 is disposed in the chamber 12 of the base 1. The moving contact of the switch module 5 extends into the reagent container placement slot 61 through the clearance hole 62 and protrudes upward from the bottom of the reagent container placement slot 61. When the reagent container 7 is placed into the reagent container placement slot 61, the bottom wall of the reagent container 7 can press the moving contact against the fixed contact, so that the moving contact and the fixed contact make contact, and the switch module 5 closes.
[0068] After the reader 2 completes the reading and writing operation of the electronic tag in the first cavity of the reagent container 7, the staff or robotic arm can remove the reagent container 7 from the base 6, rotate the reagent container 7 180°, and then put it back into the base 6 so that the electronic tag in the second cavity of the reagent container 7 is directly opposite the reader 2. At this time, the reader 2 can perform reading and writing operations on the electronic tag in the second cavity of the reagent container 7.
[0069] After all reagent containers 7 in the current batch have completed the read / write operation, the number of reagent containers 7 in the current batch is compared with the count value of counter 4 to detect whether there are any missed reads or writes in the read / write operation of reagent containers 7 in the current batch. In this embodiment, since the base 6 is fixed and cannot be rotated, after one read / write operation, the reagent container 7 needs to be removed, rotated 180°, and then placed back into the base 6. Therefore, the count value of counter 4 is equal to the number of reads and writes by reader 2, and the count value of counter 4 is also equal to twice the number of reagent containers 7 in this batch. If the comparison result does not meet the requirement that the count value of counter 4 is equal to twice the number of reagent containers 7 in this batch, it means that an error occurred during the reading / writing of the electronic tag.
[0070] See Figure 3 In the second embodiment described above, the reagent container placement slot 61 may be provided with a foolproof structure within the first slot 611 and / or the second slot 612. Preferably, the first slot 611 and the second slot 612 are groove structures of different shapes, and the first slot 611 and the second slot 612 respectively match the bottom structures of the two cavities of the reagent container 7. Because the bottom structures of the two cavities of the reagent container 7 are different, the reagent container 7 can only be placed into the reagent container placement slot 61 according to a preset orientation. In other embodiments, the foolproof structure may also be a convex bulge, rib, or protrusion, etc.
[0071] In summary, when reagent container 7 is directly placed into the mounting slot 11, reagent container 7 can trigger the switch module 5 to close, making the preset circuit conductive, at which time the reader 2 can perform a read / write operation. When reagent container 7 leaves the mounting slot 11, switch module 5 is disconnected, making the preset circuit de-energized, preparing for the read / write operation of the next reagent container 7. Counter 4 is used to calculate the number of times the preset circuit is energized. The number of energizations is related to the number of read / write operations of the reader, which facilitates comparing the number of reagent containers 7 in the batch with the counter count after all reagent containers 7 in the batch have completed the read / write operation. This helps to detect whether there are any missed reads or writes in the read / write operation of the batch of reagent containers 7, thus avoiding errors. This invention also has the advantages of simple structure and convenient operation.
[0072] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
