[0062] The present invention provides a reagent loading device and a reagent loading method, aiming to solve the problem of cumbersome operation of manually scanning barcodes on existing reagent bottles.

[0063] Please refer to Figure 1 、 Figure 3 and Figure 9The reagent loading device includes a reagent loading component 1, a reagent storage component 2 and a reagent management component 3. The reagent loading component 1 is provided with a plurality of accommodating cavities 11 arranged in sequence and used to hold reagents. The reagent storage component 2 is provided with an accommodating cavity 21 for accommodating the reagent loading component 1. The accommodating cavity 21 has a passage opening 22 that is connected to the outside and allows the reagent loading component 1 to pass through. The reagent management component 3 includes a read-write module 31 and a read-write module 32. The read-write module 31 includes a first coupling element 311 provided at the passage opening 22. Each accommodating cavity 11 is provided with a read-write module 32. The read-write module 32 is used to store information about the reagent in the corresponding accommodating cavity 11, and each read-write module 32 is provided with a second coupling element 321. When the reagent loading component 1 is loaded into the accommodating cavity 11, the read-write module 31 is used to wirelessly communicate with the second coupling element 321 in sequence through the first coupling element 311 to perform read and write operations on the read-write module 32 in sequence.

[0064] The reagent loading device of the present invention includes a reagent loading assembly 1, a reagent storage assembly 2, and a reagent management assembly 3. When reagents need to be loaded, the reagent loading assembly 1 containing the reagents in the receiving chamber 11 can be delivered into the receiving chamber 21 through the passage opening 22. At the same time, the read / write module 31 couples with the second coupling element 321 of the read / write module 32 located in each receiving chamber 11 sequentially loaded into the receiving chamber 21 via a first coupling element 311 disposed at the passage opening 22, and reads information from the read / write module 32. The information read includes: reagent batch number, reagent type, production date, expiration date after bottle opening, number of times the reagent can be used, etc. When loading reagents, the reagent loading device of the present invention couples the first coupling element 311 with the second coupling element 321, allowing the read / write module 31 to read and write reagent information to the read / write module 31 located in each receiving chamber 11. This eliminates the need for the user to scan each receiving chamber 11 with a barcode scanner, making operation convenient and effectively avoiding scanning omissions, incorrect scans, and the like. Moreover, the reagent loading device of the present invention only needs to use one read-write module 31 to read the read-write modules 32 on each accommodating cavity 11 in sequence, and only sets the first coupling element 311 at the channel mouth 22, so that the size of the read-write module 31 is reduced, the structure is compact, and the cost is low.

[0065] Please combine Figure 6 、 Figure 9As shown, in one embodiment, the reagent chamber assembly 2 includes a reagent chamber body 23, a channel opening 22 is opened on the side of the reagent chamber body 23, a receiving cavity 21 is formed in the reagent chamber body 23, and a plurality of through holes 231 connected to the receiving cavity 21 are opened through the top of the reagent chamber body 23. Each receiving cavity 11 has a sampling hole 111 connected to the outside world. The number of through holes 231 is consistent with the number of sampling holes 111 and corresponds one to one. A first coupling element 311 is provided at each through hole 231. The read-write module 31 is also used to wirelessly communicate with the corresponding second coupling element 321 through each first coupling element 311 to perform read and write operations on the corresponding read-write module 32. The reagent tank assembly 2 includes a reagent tank body 23, which can be made of aluminum, so that the reagent tank body 23 is light in weight and convenient for processing the reagent tank body 23 into an integral structure. The reagent tank body 23 can also be formed by splicing multiple plates. A receiving cavity 21 is formed in the reagent tank body 23, and the channel opening 22 can be opened on the side of the reagent tank body 23, or on the top surface of the reagent tank body 23. A top cover is provided on the top of the reagent tank body 23, and a plurality of through holes 231 communicating with the receiving cavity 21 are opened through the top cover. When the reagent loading assembly 1 is placed in the receiving cavity 21, the number of each receiving cavity 11 and the through holes 231 are consistent, and are arranged one by one. When sampling and testing are required, the reagent needle can pass through the through hole 231 and extend into the sampling hole 111 of the receiving cavity 11 to absorb the reagent. Moreover, each through hole 231 is provided with a first coupling unit, and the first coupling unit and the second coupling element 321 at the receiving cavity 11 corresponding to the through hole 231 can communicate wirelessly. The read-write module 31 can perform information reading and writing operations on the corresponding read-write module 32 through the communication between the two. For example, when the reagent in the receiving cavity 11 changes, the read-write module 31 can write or modify the information in the read-write module 32. The information written or modified includes: reagent batch number, reagent type, production date, bottle expiration date, number of times the reagent can be used, etc. When the read-write module 31 reads and writes the number of times the reagent in the read-write module 32 can be used, the user can easily determine the remaining amount of the reagent in the current receiving cavity 11 when testing the reagent, and then know how many tests it can support for a certain test item, and whether it is necessary to add reagents in time, thereby greatly facilitating reagent management. In addition, the sampling hole 111 can be sealed with a tearable film. When it is needed, the tearable film is torn off to expose the sampling hole 111, thereby protecting the reagent from external contamination during transportation.

[0066] Furthermore, the reagent loading assembly 1 is provided with a sliding structure 12, and the cavity wall of the receiving cavity 21 is provided with a guide structure 211 for slidingly cooperating with the sliding structure 12, and the extension direction of the guide structure 211 is consistent with the direction in which the reagent loading assembly 1 is loaded into the receiving cavity 21. In order to facilitate the loading of the reagent loading assembly 1 into the receiving cavity 21, the reagent loading assembly 1 is provided with a sliding structure 12, and the cavity wall of the receiving cavity 21 is provided with a guide structure 211 that is slidably connected to the sliding structure 12. Since the extension direction of the guide structure 211 is consistent with the direction in which the reagent loading assembly 1 is loaded into the receiving cavity 21, the reagent loading assembly 1 can be smoothly loaded into the receiving cavity 21, and each receiving cavity 21 on the reagent loading assembly 1 is in one-to-one correspondence with the corresponding through hole 231, so that the first coupling element 311 at each through hole 231 can be accurately matched with the second coupling element 321 at the corresponding receiving cavity 11, thereby improving the reading reliability of the reagent information. Among them, the sliding structure 12 and the guide structure 211 can be a mutually cooperating slide groove slider structure, a slide rail slider structure, a guide post and guide sleeve structure, etc.

[0067] Please combine Figure 2 、 Figure 14 The guide structure 211 is a guide groove. The bottom wall of the receiving chamber 21 is recessed inward to form the guide groove. The bottom of the reagent loading assembly 1 is provided with a sliding structure 12. The sliding structure 12 is inserted into the guide groove and slidably connected thereto. To facilitate processing, the guide structure 211 is formed as a guide groove. That is, the bottom wall of the receiving chamber 21 is processed to form a recessed guide groove. The bottom of the reagent loading assembly 1 is directly provided with the sliding structure 12. The sliding structure 12 is inserted into the guide groove and can slide along the guide groove within the receiving chamber 21, thereby facilitating the loading of the reagent loading assembly 1 into the receiving chamber 21.

[0068] Furthermore, a snap-fit block 121 is provided on each side of the sliding structure 12, and the two opposite sidewalls of the guide groove are both recessed inward to form a snap-fit groove 212. The extending direction of the snap-fit groove 212 is consistent with the direction in which the reagent loading assembly 1 is loaded into the receiving chamber 21. The snap-fit block 121 is inserted into the snap-fit groove 212 and slidably connected to the snap-fit groove 212. In order to ensure that the position of the reagent loading assembly 1 in the receiving chamber 21 is consistent, so that the sampling hole 111 on the receiving chamber corresponds to the through hole 231, and to facilitate sampling, the snap-fit block 121 is provided on each side of the sliding structure 12, and the two opposite sidewalls of the guide groove are both recessed inward to form the snap-fit groove 212. By engaging the snap-fit block 121 with the snap-fit groove 212, the reagent loading assembly 1 can be limited in the vertical direction and the width direction of the guide groove in the receiving chamber 21, thereby ensuring the consistency of the position of the reagent loading assembly 1 and improving the reliability of sampling.

[0069] In addition, since condensation water is easily generated in the receiving cavity 21, the bottom wall of the guide groove can be recessed inward to form a collection groove, and the condensation water in the receiving cavity 21 flows into the collection groove. The collection groove also has an external discharge port connected to the outside world, and the condensation water can be discharged to the outside of the receiving cavity 21 through the external discharge port.

[0070] In addition, in one embodiment, the read-write module 31 also includes a substrate 312, a control element, a card reading element and a card writing element. The substrate 312 is installed on the top of the reagent chamber assembly 2. A first avoidance hole 3121 corresponding to the through hole 231 is opened on the substrate 312. The card reading element, the card writing element and the first coupling element 311 are all arranged on the substrate 312 and are electrically connected to the control element. A first coupling element 311 is provided at each first avoidance hole 3121. The read-write module 32 also includes a read-write element electrically connected to the second coupling element 321. The control element is used to control the card reading element to read the card on the read-write element, and to control the card writing element to write the card on the read-write element. The read / write module 32 is an electronic tag equipped with a second coupling element 321, which can be an RFID antenna. The read / write module 31 includes a substrate 312, a control element, a card reader, and a card writer. The read / write module 31 is a reader / writer, and the substrate 312 is the circuit board of the reader / writer. The read / write module 31 is equipped with a first coupling element 311, which can also be an RFID antenna. The reader / writer controls the card reader through its control element to read the electronic tag and controls the card writer through its control element to write the electronic tag. The substrate 312 is provided with a plurality of first avoidance holes 3121 corresponding to the through-holes 231. The first coupling elements 311 can be arranged around the first avoidance holes 3121 or on the walls of the first avoidance holes 3121. In one embodiment, when the reagent loading component 1 is a reagent rack 13 and a reagent bottle 14 loaded on the reagent rack 13, when it is loaded into the receiving cavity 21, the RFID antenna of each reagent bottle 14 is placed in the receiving cavity 21 and corresponds to the position of the through hole 231. Thus, the reader can identify the information stored on the RFID antenna of the reagent bottle 14 through the change of the signal, and read and write each reagent position through the pre-stored sequence in the control element. The read information can be: reagent batch number, reagent type, production date, opening validity period, number of times the reagent can be used, etc.; when the reagent information on the reagent bottle 14 or the reagent position changes, the information stored in the RFID antenna of the reagent bottle 14 can be written or modified through the control element. The written or modified information can be: reagent batch number, reagent type, production date, opening validity period, number of times the reagent can be used, etc. When a reagent position is replaced, the reader will read the information of the reagents at each position from the pre-stored order, and then transmit the read information to the reagent analysis instrument; when the reagent at a certain reagent position is sampled once, the RFID chip on the reagent bottle 14 will be written by the reader, and the available number of times the reagent bottle 14 is replaced will be reduced by 1. When the available number of the reagent bottle 14 is reduced to 0, the user will be reminded to replace the reagent.

[0071] Among them, the reagent loading device also includes an insulation component 4, which includes a plurality of bin insulation plates, which are sequentially arranged around the periphery of the reagent bin 23, and the bin insulation plates located above the reagent bin 23 are provided with second avoidance holes that are the same in number and correspond one to one with the through holes 231. In order to maintain the temperature in the receiving cavity 21 at a preset temperature, the periphery of the reagent bin 23 can be surrounded by the bin insulation plates, such as by bonding them to the outside of the reagent bin 23 with double-sided tape, so that the temperature in the reagent bin 23 is protected from the influence of the external temperature. In one embodiment, the thickness of the bin insulation plates can be greater than or equal to 9 mm, which can maximize the temperature of the reagent bin 23 and make the structure of the reagent loading device compact.

[0072] Furthermore, please combine Figure 4 To achieve multiple functions, two layers of chamber insulation plates are provided above the reagent chamber 23. These plates are, from top to bottom, the first insulation plate 41 and the second insulation plate 42. The base plate 312 is located between the first insulation plate 41 and the second insulation plate 42, and the second avoidance holes penetrate the first insulation plate 41 and the second insulation plate 42 in sequence. To protect the base plate 312 of the read / write module 31 from being corroded and burned by condensed water, chamber insulation plates are provided on both the upper and lower sides of the base plate 312. The first insulation plate 41 is located above the base plate, and the second insulation plate 42 is located below the base plate.

The sensor 51 is used to sense the attraction between the first attraction member 52 and the second attraction member 53. In order to enable the reagent loading component 1 to be installed in place in the receiving chamber 21, a first attraction member 52 can be set on the reagent loading component 1, and a second attraction member 53 can be set on the cavity wall of the receiving chamber 21.

The cooling element 621 and the heat sink 622 are both arranged corresponding to the installation opening 611. The side of the cooling element 621 away from the installation opening 611 abuts the reagent compartment assembly 2. The refrigeration element 63 is arranged within the installation opening 611 and includes a cold end and a hot end. The cold end abuts the cooling element 621, and the hot end abuts the heat sink 622. In order to adjust the temperature within the receiving chamber 21 to a better temperature for storing the reagents, a refrigeration mechanism 6 can be provided to cool the reagent compartment body 23, thereby adjusting the temperature within the receiving chamber 21 to the reagent storage temperature. The fixing base 61 of the refrigeration mechanism 6 is provided with an installation opening 611, and the refrigeration element 63 is installed at the installation opening 611. One end of the cold conducting element 621 is in contact with the outer side surface of the reagent storage body 23, and the other end is connected to the cold end of the refrigeration element 63. The cold end of the refrigeration element 63 transfers the low temperature to the cold conducting element 621, and the low temperature is transferred to the reagent storage body 23 through the cold conducting element 621, thereby cooling the temperature in the receiving cavity 21 of the reagent storage body 23. Moreover, the hot end of the refrigeration element 63 is in contact with the heat sink 622, and the heat sink 622 transfers the high temperature of the hot end of the refrigeration element 63 to the outside world, fully dissipating heat from it, thereby improving the cooling and heat dissipation efficiency of the refrigeration mechanism 6.

The locking bolt 64 is passed through the through hole and screwed into the mounting hole to connect the fixing base 61 and the heat sink 622, thereby ensuring the assembly security of the refrigeration mechanism 6. Furthermore, since the refrigeration component 63 is abutted between the heat dissipation component 622 and the cooling conductor 621, in order to protect the refrigeration component 63, an elastic sleeve 65, such as a compression spring, can be sleeved on the outer periphery of the locking bolt 64. The elasticity of the compression spring can be used to control the locking force of the locking bolt 64, thereby preventing the refrigeration component 63 from being crushed.

[0081] Moreover, in order to isolate the temperatures between the hot end and the cold end of the refrigeration component 63 from each other, thermal insulation glue can be sealed in the gap between the heat sink 622 and the refrigeration plate. The thermal insulation glue seals this area and can also prevent external water vapor from flowing onto the refrigeration component 63 and damaging the refrigeration component 63.

In order to protect the temperature in the receiving chamber 21 from the influence of the external temperature, a door assembly 7 can be provided, and the passage opening 22 can be closed by the door assembly 7. When the reagent loading assembly 1 needs to be loaded into the receiving chamber 21, the door assembly 7 can be opened, so that the reagent loading assembly 1 can be loaded into the receiving chamber 21 through the passage opening 22. The door assembly 7 is connected to the reagent chamber assembly 2 by a hinge mechanism 8. The hinge mechanism 8 includes a first hinge seat 81, a second hinge seat 82 and a hinge shaft 83.

Abutting between the abutting section and the second hinge seat 82, the elastic pad 831 can eliminate the gap between the first hinge seat 81 and the second hinge seat 82, preventing the first hinge seat 81 and the second hinge seat 82 from shaking along the length direction of the hinge shaft 83, thereby ensuring that the door assembly 7 shakes when opening or closing the channel opening 22, thereby avoiding the resulting displacement of the reagent loading assembly 1 in the receiving chamber 21. In other embodiments, the elastic pad 831 can also be provided between the first hinge seat 81 and the second hinge seat 82. It should be noted that either the first hinge seat 81 or the second hinge seat 82 can be connected to the reagent chamber assembly 2 by bolts, and the other can be connected to the door assembly 7 by bolts, that is, the first hinge seat 81 is connected to the reagent chamber assembly 2, and the second hinge seat 82 is connected to the door assembly 7, or the first hinge seat 81 is connected to the door assembly 7, and the second hinge seat 82 is connected to the reagent chamber assembly 2.

The setting of the first protrusion 812 and the second protrusion 822 can prevent the first hinge seat 81 and the second hinge seat 82 from interfering with each other during rotation. The elastic pad 831 can be set between the first protrusion 812 and the second protrusion 822, or between the second protrusion 822 and the abutment section. In addition, a wear-resistant pad can be set between any two adjacent ones of the first protrusion 812, the second protrusion 822, the abutment section and the elastic pad 831. The wear-resistant pad can be a plastic pad, so as to prevent the wear between any two adjacent ones and the generation of new gaps, and prevent noise when the first hinge seat 81 and the second hinge seat 82 rotate relative to each other.

[0084] Furthermore, a limiting protrusion 813 is provided on the first hinge seat 81, and an abutting strip 823 is protruded from the second hinge seat 82.

The limiting protrusion 813 is used to abut against the abutting strip 823. In one embodiment, when the hinge mechanism 8 is arranged at the bottom of the reagent chamber assembly 2, if the chamber door assembly 7 needs to be opened from a vertical state to a horizontal state so that the reagent loading assembly 1 can be supported by the chamber door assembly 7 and pass through the channel opening 22 to be loaded into the receiving cavity 21, it is necessary to open the chamber door assembly 7 at an opening and closing angle of 90°.

[0085] Please combine Figure 10 In one embodiment, the door assembly 7 includes a door body 71 and a door insulation plate 72 that are interconnected. The door insulation plate 72 is provided with an abutment member 721. The abutment member 721 is used to abut the reagent loading assembly 1 in the receiving chamber 21 after the door body 71 closes the passage opening 22.

When the door assembly 7 closes the passage opening 22, the abutment member 721 can abut the reagent loading assembly 1 between the abutment member 721 and the wall of the receiving chamber 21 away from the passage opening 22.

[0086] In addition, the present invention also provides a reagent loading method, which is applied to the reagent loading device described above. The reagent loading method includes the following steps:

[0087] Step S01, installing a read-write module storing reagent information in a receiving cavity containing reagents;

[0088] Step S02: loading the reagent loading assembly into the receiving cavity of the reagent compartment assembly through the passage opening of the reagent compartment assembly;

[0089] In step S03 , the read / write module wirelessly communicates with the second coupling element in sequence through the first coupling element, so as to perform read / write operations on the read / write module in sequence.

[0090] In the present embodiment, when it is necessary to load the reagent, the read / write module storing the reagent information is installed at the accommodating chamber containing the reagent, and the reagent loading assembly containing the reagent in the accommodating chamber is sent into the accommodating chamber through the passageway. At the same time, the read / write module is coupled with the second coupling element on the read / write module at each accommodating chamber that is sequentially loaded into the accommodating chamber by the first coupling element arranged at the passageway, and the read / write module is read. The information read includes: reagent batch number, reagent type, production date, bottle expiration date, number of times the reagent can be used, etc. When the reagent loading device of the present invention is loaded, the read / write module reads and writes the reagent information to the read / write module at each accommodating chamber through the coupling of the first coupling element and the second coupling element, thereby eliminating the need for the user to scan the barcode of each accommodating chamber with a barcode scanner, and is easy to operate and can effectively avoid situations such as scanning omissions and scanning errors. Moreover, the reagent loading device of the present invention only needs to read the read / write modules on each accommodating chamber in sequence through a read / write module, and only the first coupling element is arranged at the passageway, so that the size of the read / write module is reduced, the structure is compact, and the cost is low.

[0091] Furthermore, in one embodiment, the above step S02 further includes the following steps:

[0092] Step S04, aligning the sampling holes on each receiving cavity of the reagent loading assembly with the through holes of the reagent compartment assembly one by one;

[0093] Step S05 , performing read and write operations on the corresponding read and write modules by wirelessly communicating with the second coupling elements of the read and write modules at the corresponding accommodating cavities based on the first coupling elements at the through holes of the read and write modules.

[0094] When the reagent loading assembly is placed in the receiving chamber, the number of each receiving chamber and the through hole is consistent, and they are arranged in a one-to-one correspondence. When sampling and testing are required, the reagent needle can pass through the through hole and extend into the sampling hole of the receiving chamber to absorb the reagent. Moreover, each through hole is provided with a first coupling unit, and the first coupling unit can communicate wirelessly with the second coupling element at the receiving chamber corresponding to the through hole. The read-write module can perform information reading and writing operations on the corresponding read-write module through the communication between the two. For example, when the reagent in the receiving chamber changes, the read-write module can write or modify the information in the read-write module. The information written or modified includes: reagent batch number, reagent type, production date, bottle expiration date, number of times the reagent can be used, etc. When the read-write module reads and writes the number of times the reagent in the read-write module can be used, the user can easily judge the remaining amount of the reagent in the current receiving chamber when testing the reagent, and then know how many tests it can support for a certain test item, and whether it is necessary to add reagents in time, thereby greatly facilitating reagent management. In addition, a tearable film can be sealed at the sampling hole. When it is needed, the tearable film is torn off to expose the sampling hole, thereby protecting the reagent from external contamination during transportation.

[0095] The read / write module can be an electronic tag, provided with a second coupling element, which can be an RFID antenna. The read / write module includes a substrate, a control element, a card reader element, and a card writer element. The read / write module is a reader / writer, and the substrate is the circuit board of the reader / writer. The read / write module is provided with a first coupling element, which can also be an RFID antenna. The reader / writer controls the card reader element through its control element to read the electronic tag, and also controls the card writer element through its control element to write the electronic tag. The substrate is provided with multiple first avoidance holes corresponding to the through holes. The first coupling elements can be arranged around the first avoidance holes or on the walls of the first avoidance holes. In one embodiment, when the reagent loading component is a reagent rack and reagent bottles loaded on the reagent rack, when it is loaded into the receiving cavity, the RFID antenna of each reagent bottle is placed in the receiving cavity and corresponds to the through-hole position. Thus, the reader can identify the information stored on the reagent bottle RFID antenna through changes in the signal, and read and write each reagent position through the pre-stored sequence in the control element. The read information can be: reagent batch number, reagent type, production date, bottle expiration date, number of times the reagent can be used, etc.; when the reagent information on the reagent bottle or reagent position changes, the information stored in the reagent bottle RFID antenna can be written or modified through the control element. The written or modified information can be: reagent batch number, reagent type, production date, bottle expiration date, number of times the reagent can be used, etc. When a reagent position is replaced, the reader will read the information of the reagents at each position from the pre-stored order, and then transmit the read information to the reagent analyzer; when the reagent at a certain reagent position is sampled once, the reader will write to the RFID chip on the reagent bottle, and the available number of times the reagent bottle is replaced will be reduced by 1. When the available number of the reagent bottle is reduced to 0, the user will be reminded to replace the reagent.
