Description

[0001] The application belongs to the technical field of medical equipment, and particularly relates to a multi-channel multi-association POCT full-automatic chemiluminescence equipment. BACKGROUND

[0002] Chemiluminescence immunoassay technology, as a rapidly developed non-radioactive immunoassay technology, has become one of the important directions of immunological detection, and its principle is to directly determine the immune reaction by using a chemiluminescence signal. The chemiluminescence equipment using the chemiluminescence immunoassay technology has the advantages of high sensitivity, good repeatability, high accuracy, good specificity and wide linear range.

[0003] POCT (Point-Of-Care Testing) is a detection method of performing clinical detection on a sampling site immediately, omitting the complex processing procedures of sample detection in a laboratory, and then quickly obtaining a detection result, and has the characteristics of simple instrument programming, easy operation and rapid report result.

[0005] The multi-channel multi-association POCT full-automatic chemiluminescence equipment generally comprises a reaction bin module and a multi-channel parallel pretreatment module, the reaction bin module loads a reagent strip in which various reagents are sealed, and moves the reagent strip to the multi-channel parallel pretreatment module for corresponding treatment, such as breaking the sealing film on the reagent hole, transferring magnetic particles and the like. The length of the reagent strip is affected by the number of detection items, and the reagent strip needs to be increased accordingly, and then the length of the reagent strip is also increased.

[0006] When the equipment is used for detection and analysis of multiple items, the distance that the reaction bin module needs to move with the reagent strip in the equipment will be increased, so as to move the reagent strip to the multi-channel parallel pretreatment module for corresponding treatment, such as breaking the sealing film on the reagent strip by moving a long distance, which will cause the volume of the equipment to increase, is not conducive to the miniaturization of the equipment, and will also prolong the detection and diagnosis result time.

The handle 22 can be provided with anti-slip lines to improve the friction between the multi-association reagent strip 20 and the fingers of the operator, thereby facilitating the operator to hold it tightly.

[0119] The handle 22 is sequentially provided with the sample hole 23, the tip head hole, the at least two disposable magnetic separation sleeve holes, the at least two magnetic labeled ligand holes, the at least two enzyme labeled ligand holes, the plurality of cleaning liquid holes and the plurality of substrate reading holes (i.e. the above-mentioned detection sites) in the direction from one end of the handle 22 to the other end of the multi-association reagent strip 20. The magnetic labeled ligand holes and the enzyme labeled ligand holes constitute the special liquid area 2111, the cleaning liquid holes and the substrate reading holes constitute the common liquid area 2112, and the special liquid area 2111 and the common liquid area 2112 constitute the liquid storage area 211.

[0120] The sample hole 23 is used for adding a blood sample, the tip head hole is provided with a tip head 24, the disposable magnetic separation sleeve hole is provided with a disposable magnetic separation sleeve 25, the magnetic label ligand hole contains a magnetic label ligand, and the enzyme label ligand hole contains an enzyme label ligand. The ligand includes but is not limited to hapten, antigen, monoclonal antibody, polyclonal antibody, and nucleic acid ligand. The washing liquid hole contains a washing liquid, and the substrate reading hole contains a substrate reading. The number of rows of the magnetic rod 4331 is equal to the number of disposable magnetic separation sleeve holes, magnetic label ligand holes, enzyme label ligand holes, and substrate reading holes.

[0121] In addition, after the corresponding reagents are packaged in the corresponding hole positions of the multi-item detection reagent strip 20, the surface of the multi-item detection reagent strip 20 can be heat-sealed with a film to prevent the reagents in the hole positions from leaking or being contaminated, and to facilitate storage and transportation of the multi-item detection reagent strip 20.

[0122] The tip head 24 is a hollow structure with a sharp end, and a through hole is formed in the end, so that the tip head 24 can be used to transfer samples or reagents, and can also be used to break the sealing film on the hole positions. The disposable magnetic separation sleeve 25 can be used to adsorb, mix, wash, and transfer magnetic microparticles. The washing liquid hole can be used to wash the magnetic microparticles. The substrate reading hole is used for chemiluminescence reaction and reading of the luminescence value.

[0123] In the embodiment of the present application, the special liquid area 2111 can be understood as a component directly related to the detection item (such as magnetic bead labeled ligand, enzyme labeled ligand, and pretreatment liquid), wherein the ligand includes hapten, antigen, antibody, and nucleic acid probe, etc. The common liquid area 2112 can be understood as a component that can be shared among detection items (such as washing liquid and luminescence liquid).

[0124] In the common liquid area 2112, even if the film breaking assembly 50 contaminates the liquid in one hole position in the previous film breaking process, and then contaminates the liquid in other hole positions, it will not have a significant impact on the detection result. Therefore, the film breaking assembly 50 is designed to break the sealing film of the common liquid area 2112, reduce the film breaking work of the multi-channel multi-item detection parallel pretreatment device 40, shorten the moving distance of the reaction chamber assembly 30, control the size of the equipment, and improve the multi-item analysis efficiency of the equipment.

[0125] Since the reaction chamber assembly 30 is arranged on the bottom plate of the mounting frame 10, the PMT assembly 60 can be arranged above the bottom plate by a support or the like, that is, the PMT assembly 60 is located opposite the reaction chamber assembly 30. To ensure that the PMT assembly 60 can detect the luminescence values of all the multi-association reagent strips 20 in the reaction chamber assembly 30, the PMT assembly 60 can move up and down and left and right in the mounting frame 10, that is, can move in the vertical direction and the horizontal direction (the width direction of the mounting frame 10), so as to move close to, away from, and between the multi-association reagent strips 20.

[0126] Similarly, the multi-channel multi-association parallel pre-processing device 40 can also be arranged above the bottom plate by a support or the like, that is, the multi-channel multi-association parallel pre-processing device 40 is located opposite the reaction chamber assembly 30. To ensure that the multi-channel multi-association parallel pre-processing device 40 can pre-process all the multi-association reagent strips 20 in the reaction chamber assembly 30, the multi-channel multi-association parallel pre-processing device 40 can also move up and down in the mounting frame 10, that is, can move in the vertical direction, so as to move close to, away from, and between the multi-association reagent strips 20 to transfer samples or reagents, break the sealing film on the multi-association reagent strip 20 hole, and adsorb, mix, clean, and transfer magnetic particles.

[0127] In the embodiment of the present application, the multi-channel multi-association parallel pre-processing device 40 can include two structures, one structure is used in combination with the tip head 24 to transfer samples or reagents and break the sealing film of each hole, and the other structure is used in combination with the disposable magnetic separation sleeve 25 to adsorb, mix, clean, and transfer magnetic particles.

[0128] Further, the multi-channel multi-association parallel pre-processing device 40 includes:

[0129] The gantry 41 arranged on the bottom plate of the mounting frame 10, and the top of the gantry 41 is provided with a first driving element 411;

[0130] The sample extraction mechanism 42 arranged on the gantry 41, and the sample extraction mechanism 42 is in transmission connection with the first driving element 411 and can be lifted and lowered under the driving of the first driving element 411 to suck and spit the sample on the multi-association reagent strip 20;

[0131] The sample pre-processing mechanism 43 arranged on the gantry 41, and the sample pre-processing mechanism 43 is in transmission connection with the first driving element 411 and can be lifted and lowered under the driving of the first driving element 411, and at least two rows of magnetic rods 4331 are arranged on the sample pre-processing mechanism 43 to transfer the magnetic particles on the multi-association reagent strip 20.

[0132] Specifically, the gantry 41 can be made of metal materials, such as stainless steel, iron, aluminum, and various alloys, etc., with high strength, which can improve the service life of the multi-channel pre-processing device 40. The gantry 41 spans the width direction of the installation frame 10, so that the sample extraction mechanism 42 and the sample pre-processing mechanism 43 can span above the reaction chamber assembly 30 to realize multi-channel parallel pre-processing.

[0133] In the embodiment of the present application, the first driving element 411 can be a lead screw motor, which has high motion accuracy and is more accurate and stable in position adjustment. The first driving element 411 arranged at the top of the gantry 41 drives the sample extraction mechanism 42 and the sample pre-processing mechanism 43 to ascend and descend on the gantry 41, so that the sample extraction mechanism 42 and the sample pre-processing mechanism 43 are close to or away from the multi-association reagent strip 20, thereby enabling the sample extraction mechanism 42 and the multi-association reagent strip 20 to be in close contact or away from each other, and the sample pre-processing mechanism 43 and the multi-association reagent strip 20 to be in close contact or away from each other. p The head 24 cooperates to realize the functions of film breaking, sample transfer or reagent transfer, etc., and the sample pre-processing mechanism 43 cooperates with the disposable magnetic separation sleeve 25 on the multi-association reagent strip 20 to realize the adsorption, mixing, washing and transfer of magnetic particles, etc.

[0134] In addition, the sample pre-processing mechanism 43 and the sample extraction mechanism 42 are arranged on opposite sides of the gantry 41, for example, the sample pre-processing mechanism 43 is arranged on the side of the gantry 41 close to the PMT assembly 60, and the sample extraction mechanism 42 is arranged on the other side of the gantry 41.

[0135] In this way, it can not only avoid the problem of space crowding, heavy weight, inconvenient operation and unstable structure of the gantry 41 caused by arranging the sample pre-processing mechanism 43 and the sample extraction mechanism 42 on the same side of the gantry 41, but also enable the sample extraction mechanism 42 and the sample pre-processing mechanism 43 to correspond to different functional reagent holes on the multi-association reagent strip 20, for example, the front part of the multi-association reagent strip 20 needs more participation of the sample extraction mechanism 42, and the rear part needs more participation of the sample pre-processing mechanism 43, which can further improve the pre-processing speed of the multi-channel multi-association parallel pre-processing device 40 on the multi-association reagent strip 20.

[0136] Please refer to FIGS. 6 to 12, further, the sample pre-processing mechanism 43 comprises:

[0137] The first mounting frame 431 arranged on the gantry 41 and in transmission connection with the first driving element 411, the first driving element 411 can drive the first mounting frame 431 to ascend and descend;

[0138] The second driving element 432 arranged on the first mounting frame 431; and

[0139] The front treatment component 433 is arranged on the first mounting frame 431 and is in transmission connection with the second driving element 432. The second driving element 432 can drive the front treatment component 433 to move in the vertical direction to transfer the magnetic microparticles.

[0140] Specifically, the first driving element 411 can drive the first mounting frame 431 to move up and down, thereby driving the sample front treatment mechanism 43 to move up and down to perform corresponding processing such as transferring magnetic microparticles on the multi-test reagent strip 20. The first mounting frame 431 can be substantially in the shape of "L" and include two parts, such as a horizontal extension plate and a vertical extension plate. The second driving element 432 can be arranged on the horizontal extension plate to ensure stable arrangement, thereby providing stable power for the up and down movement of the front treatment component 433.

[0141] The front treatment component 433 is arranged on the vertical extension plate. The second driving element 432 can be a lead screw motor. The lead screw motor has high movement precision and is more accurate and stable in position adjustment. The transmission shaft (i.e., the transmission lead screw) of the lead screw motor extends downward through the horizontal extension plate and is in transmission connection with the front treatment component 433. The transmission connection between the two can be screw connection, which can ensure the stability of the connection between the two. Meanwhile, the second driving element 432 can drive the front treatment component 433 to move in the vertical direction stably and accurately through screw driving, thereby stably and accurately adsorbing and then transferring the magnetic microparticles.

[0142] Further, to ensure that the front treatment component 433 moves up and down stably on the first mounting frame 431, a slide rail extending in the vertical direction can be arranged on the first mounting frame 431, and a slide block adapted to the slide rail can be arranged on the first pushing plate 4334. The stable movement of the front treatment component 433 on the first mounting frame 431 can be realized through the cooperation of the slide rail and the slide block.

[0143] In addition, a first detector (such as a photoelectric switch) can be arranged on one side of the top of the gantry 41, and a first sensing element (such as a baffle) can be arranged on one side of the top of the first mounting frame 431. The first sensing element can be in sensing or out of sensing with the first detector as the first mounting frame 431 moves up and down. When the first mounting frame 431 moves the first sensing element to the first detector to make it out of sensing, it indicates that the sample front treatment mechanism 43 has moved to the set height. At this time, the power supply of the first driving element 411 can be disconnected to avoid overloading and damage of the first driving element 411 and save power consumption.

[0144] Further, one side of the first mounting frame 431 facing the gantry 41 can be provided with a first sliding seat 4311, and one side of the gantry 41 facing the first mounting frame 431 can be provided with a first slide rail 414 extending in the height direction of the gantry 41. The first sliding seat 4311 is in sliding connection with the first slide rail 414.

[0145] The first sliding seat 4311 and the first sliding rail 414 are two groups, which are respectively arranged on the left and right sides of the gantry 41 and the first mounting frame 431. Through cooperation of the two groups of first sliding seat 4311 and first sliding rail 414, the stable lifting of the first mounting frame 431 on the gantry 41 driven by the first driving element 411 can be ensured, and in turn, the stable and accurate lifting of the sample extraction mechanism 42 can be ensured.

[0146] In the embodiment of the present application, the sample extraction mechanism 42 is opposite to the sample pretreatment mechanism 43 on the gantry 41, and the sample extraction mechanism 42 is located in front of the sample pretreatment mechanism 43. The first driving element 411, the second driving element 432 and the third driving element 422 are linearly arranged on the top of the gantry 41, so that the top structure of the multi-channel multi-association inspection parallel pretreatment device 40 is distributed regularly, and the three driving elements are basically concentrated in the middle part of the gantry 41 when force is exerted, so that the gantry 41 is not easy to shake and deviate.

[0147] Please refer to FIG. 9 and FIG. 12, further, the pretreatment assembly 433 comprises:

[0148] A magnetic rod device 4332 arranged on the first mounting frame 431, a plurality of movable through holes are formed in the magnetic rod device 4332, and a first loading head 4333 for loading a disposable magnetic separation sleeve 25 is arranged at the bottom of the magnetic rod device 4332, the first loading head 4333 is in communication with the movable through holes;

[0149] A first push plate 4334 arranged above the magnetic rod device 4332, the first push plate 4334 is in transmission connection with the second driving element 432; and

[0150] A plurality of connecting rods 4335 arranged on the first push plate 4334, at least two rows of magnetic rods 4331 are arranged on the free ends of the plurality of connecting rods 4335 one by one, and the second driving element 432 can drive the first push plate 4334 to drive the magnetic rods 4331 to lift in the corresponding movable through holes, so as to be spaced apart from or pass through the first loading head 4333.

[0151] Specifically, the magnetic rod device 4332 is roughly in the shape of a cuboid, which is distributed along the width direction of the first mounting frame 431, so that the movable through holes therein can be distributed in the width direction of the pretreatment assembly 433 to correspond to the positions of the multi-association inspection reagent strip 20.

[0152] When the disposable magnetic separation sleeve 25 needs to be loaded, the first driving element 411 drives the first mounting frame 431 to descend to the first loading head 4333 to contact and load the disposable magnetic separation sleeve 25, and the two are in interference fit, so as to ensure the stability of the disposable magnetic separation sleeve 25 loaded on the first loading head 4333, and also facilitate separation. The first loading head 4333 is in communication with the movable hole, so that the movable hole is in communication with the disposable magnetic separation sleeve 25, and when the second driving element 432 drives the connecting rod 4335 to drive the magnetic rod 4331 to pass through the first loading head 4333 to extend into the disposable magnetic separation sleeve 25, the magnetic microparticles can be adsorbed through the disposable magnetic separation sleeve 25.

[0153] When the disposable magnetic separation sleeve 25 needs to be separated, the second driving element 432 is controlled to drive the magnetic rod 4331 to descend to abut against the bottom end of the disposable magnetic separation sleeve 25, so that the disposable magnetic separation sleeve 25 is removed from the first loading head 4333. When the second driving element 432 drives the connecting rod 4335 to drive the magnetic rod 4331 to separate from the first loading head 4333 and separate from the disposable magnetic separation sleeve 25, the magnetic field generated by the magnetic rod 4331 disappears, and the magnetic microparticles are separated from the disposable magnetic separation sleeve 25 to realize transfer.

[0154] Based on the design of at least two rows of magnetic rods 4331 in the pretreatment assembly 433, at least two rows of disposable magnetic separation sleeves 25 can be loaded at a time, and at least two magnetic microparticles in the reagent hole can be transferred at a time through at least two rows of disposable magnetic separation sleeves 25. Not only can the transfer speed of the magnetic microparticles be improved to ensure the analysis efficiency of the equipment, but also the multi-association detection function of the equipment can be realized.

[0155] In addition, on the basis of transferring the magnetic microparticles, the pretreatment assembly 433 combined with the disposable magnetic separation sleeve 25 can also be used to transfer the magnetic microparticles to the reagent for reaction and mixing, or separate the magnetic microparticles in the reaction solution to the cleaning solution, or transfer the magnetic microparticles to the substrate reading for reaction and complete the luminescence detection.

[0156] The transmission shaft of the second driving element 432 extends downward through the top of the first mounting frame 431 and the first pushing plate 4334. A fixing member can be provided on the transmission shaft and screwed with the transmission shaft, and the first pushing plate 4334 is fixed on the fixing member. When the transmission shaft of the second driving element 432 acts, the first pushing plate 4334 can be lifted through the fixing member to realize the lifting of the magnetic rod 4331.

[0157] Alternatively, a threaded hole can also be directly provided on the first pushing plate 4334, and a thread is provided on the transmission shaft of the second driving element 432. The transmission shaft is screwed with the first pushing plate 4334 (threaded hole), so as to ensure the stability of the connection between the two, and the second driving element 432 can also drive the first pushing plate 4334 to stably ascend and descend through the threaded driving mode.

[0158] Referring to FIG. 9 and FIG. 12, further, the magnetic rods 4331 are in multiple rows, the multiple rows of magnetic rods 4331 are evenly distributed along the width direction of the first push plate 4334, the number of rows of magnetic rods 4331 is equal to the number of substrate reading holes, so as to realize detection of multiple items, that is, realize multi-association detection.

[0159] Each row of magnetic rods 4331 is multiple, the multiple magnetic rods 4331 in each row are evenly distributed along the length direction of the first push plate 4334, the number of magnetic rods 4331 in each row is equal to the number of multi-association detection reagent strips 20, so as to realize multi-channel parallel processing of multiple multi-association detection reagent strips 20.

[0160] In the embodiment of the application, the magnetic rods 4331 are in 3 rows, that is, 3 items can be detected, the space occupied by the 3 rows of magnetic rods 4331 is not too large, and 3 items can be detected, so that the volume of the multi-channel multi-association detection POCT full-automatic chemiluminescence equipment 100 can be controlled while multi-association detection is realized.

[0161] Of course, in other embodiments, the magnetic rods 4331 can also be in 2 rows or 4 rows or even more, so as to realize detection of different numbers of items.

[0162] The sample pretreatment mechanism 43 in the embodiment of the application can drive the magnetic rods 4331 to reciprocate by lifting and lowering the magnetic rods 4331 through the second driving element 432, the efficiency of magnetic separation is higher, and the multi-channel parallel separation processing further improves the separation and transfer efficiency of magnetic particles. At the same time, the reciprocating motion of the disposable magnetic separation sleeve 25 is realized through the second driving element 432, and the mixing of the reaction liquid and the resuspension of the cleaning liquid can also be completed.

[0163] Exemplarily, the process of the sample pretreatment mechanism 43 transferring magnetic particles is as follows:

[0164] After the sample is injected into the corresponding reagent hole of the multi-association detection reagent strip 20, the reaction chamber assembly 30 drives the multi-association detection reagent strip 20 to move to the corresponding position, so that the sample pretreatment mechanism 43 is located directly above the disposable magnetic rod 4331 sleeve, at this time, the first driving element 411 drives the first mounting frame 431 to lower by a certain height, so that the disposable magnetic rod 4331 sleeve is loaded on the first loading head 4333, the first driving element 411 drives the first mounting frame 431 to rise, and the disposable magnetic rod 4331 sleeve is driven by the first loading head 4333 to rise to a certain height.

[0165] Afterwards, the reaction chamber assembly 30 moves to the position above the corresponding hole of the multi-well test strip 20, the first driving element 411 drives the first mounting frame 431 to lower until the disposable magnetic separation sleeve 25 is inserted into the liquid containing magnetic particles (such as the magnetic labeled ligand as described above), and the second driving element 432 drives the magnetic rod 4331 to lower until the magnetic rod 4331 contacts the bottom of the disposable magnetic separation sleeve 25. At this time, the magnetic particles are gradually adsorbed to the end of the disposable magnetic separation sleeve 25. The adsorption of the magnetic particles can be completed by multiple slow lifting and lowering operations.

[0166] After the adsorption of the magnetic particles is completed, the first driving element 411 is controlled to drive the first mounting frame 431 to rise. At this time, the magnetic particles are all adsorbed to the outer wall of the disposable magnetic separation sleeve 25. The reaction chamber assembly 30 is moved to the position above the washing liquid, and the first driving element 411 is controlled to drive the first mounting frame 431 to lower until the disposable magnetic separation sleeve 25 is inserted into the washing liquid. Afterwards, the second driving element 432 is controlled to drive the magnetic rod 4331 to rise from the disposable magnetic separation sleeve 25, so that the magnetic field disappears, and the magnetic particles are separated from the outer wall of the disposable magnetic separation sleeve 25 and fall into the washing liquid.

[0167] In order to accelerate the separation process of the magnetic particles, the first driving element 411 can drive the first mounting frame 431 to repeatedly rise and fall at different frequencies, so that the magnetic particles repeatedly move in the washing liquid, thereby ensuring that the magnetic particles are fully mixed and suspended in the washing liquid. After the magnetic particles are completely separated from the outer wall of the disposable magnetic separation sleeve 25, the first driving element 411 drives the first mounting frame 431 to rise to the initial height, thereby completing the separation, washing and mixing of the magnetic particles. If multiple magnetic separation and washing operations are required, the above operations can be repeated.

[0168] Similarly, if it is required to transfer the magnetic particles to other holes, the first driving element 411 is controlled to drive the first mounting frame 431 to lower until the disposable magnetic separation sleeve 25 is inserted into the bottom of the corresponding liquid surface. Then, the second driving element 432 is controlled to drive the magnetic rod 4331 to lower until the magnetic rod 4331 contacts the bottom end of the disposable magnetic separation sleeve 25, so that the magnetic particles are all adsorbed to the outer wall of the disposable magnetic separation sleeve 25. The first driving element 411 is controlled to drive the first mounting frame 431 to rise.

[0169] Afterwards, the reaction chamber assembly 30 is controlled to move, and the disposable magnetic separation sleeve 25 with the adsorbed magnetic particles is moved to be directly above the target hole position. Then the first driving element 411 is controlled to drive the first mounting frame 431 to descend, and the disposable magnetic separation sleeve 25 is extended into the target liquid. At this time, the second driving element 432 is controlled to drive the magnetic rod 4331 to ascend, so that the magnetic field disappears. The magnetic particles can be gradually separated into the target liquid. The first driving element 411 can be repeatedly controlled to drive the first mounting frame 431 to ascend and descend, so that the disposable magnetic separation sleeve 25 repeatedly moves in the target liquid, thereby accelerating the separation of the magnetic particles.

[0170] Further, referring to FIGS. 6-11 and 13, the sample extraction mechanism 42 includes:

[0171] The second mounting frame 421 is arranged on the gantry 41 and is in transmission connection with the first driving element 411. The first driving element 411 can drive the second mounting frame 421 to ascend and descend;

[0172] The third driving element 422 is arranged on the second mounting frame 421; and

[0173] The extraction assembly 423 is arranged on the second mounting frame 421 and is in transmission connection with the third driving element 422. The third driving element 422 can drive the extraction assembly 423 to ascend and descend to suck and spit the sample.

[0174] Specifically, the first driving element 411 can drive the second mounting frame 421 to ascend and descend, thereby driving the sample extraction mechanism 42 to ascend and descend to perform corresponding processing such as sucking and spitting the sample on the multi-reagent strip 20. The second mounting frame 421 can be substantially in the shape of "L" and include two parts, such as a horizontal extension plate and a vertical extension plate. The third driving element 422 can be arranged on the horizontal extension plate to ensure stable arrangement, thereby providing stable power for the ascent and descent of the extraction assembly 423.

[0175] The extraction assembly 423 is arranged on the vertical extension plate. The third driving element 422 can be a lead screw motor. The lead screw motor has high movement precision and is more accurate and stable in position adjustment. The transmission shaft (i.e., the transmission screw rod) of the lead screw motor extends downward through the horizontal extension plate and is in transmission connection with the extraction assembly 423. The transmission connection between the two can be screw connection, which can ensure the stability of the connection between the two. Meanwhile, the third driving element 422 can drive the extraction assembly 423 to move stably and accurately in the vertical direction through screw driving, thereby stably and accurately contacting the sample to suck and spit the sample.

[0176] In addition, a second detector (such as a photoelectric switch) can be arranged on one side of the top of the gantry 41, and a second sensing member (such as a baffle) can be arranged on one side of the top of the second mounting frame 421. The second sensing member can be in sensing connection or disconnected with the second detector as the second mounting frame 421 ascends and descends.

[0177] When the second mounting frame 421 drives the second sensing member to move to the second detector to disconnect the induction, it indicates that the sample extraction mechanism 42 has moved to the set height, at this time the power supply of the first driving element 411 can be disconnected to avoid the first driving element 411 being damaged due to overload, and also save power consumption.

[0178] Further, the second mounting frame 421 can be provided with a second sliding seat 4211 on one side of the gantry 41, and the gantry 41 can be provided with a second sliding rail 415 extending along the height direction of the gantry 41 on one side of the gantry 41, and the second sliding seat 4211 is in sliding connection with the second sliding rail 415.

[0179] Moreover, the second mounting frame 421 and the second sliding seat 4211 and the second sliding rail 415 on the gantry 41 are two groups, which are respectively arranged on the left and right sides of the gantry 41 and the second mounting frame 421. In this way, through the cooperation between the two groups of second sliding seats 4211 and second sliding rails 415, the stable lifting of the first driving element 411 driving the second mounting frame 421 on the gantry 41 can be ensured, and further the stable and accurate lifting of the sample extraction mechanism 42 can be ensured, and the stable operation of the equipment can be ensured.

[0180] Please refer to FIG. 13, further, the extraction assembly 423 comprises:

[0181] a second injection member 4231 arranged on the second mounting frame 421, a plurality of injection cavities are formed in the second injection member 4231, and a plurality of second loading heads 4232 for loading tip heads 24 are arranged on the bottom of the second injection member 4231, and the plurality of second loading heads 4232 are in one-to-one correspondence with the plurality of injection cavities;

[0182] a second pushing plate 4233 arranged above the second injection member 4231, and the second pushing plate 4233 is in transmission connection with the third driving element 422; and

[0183] a plurality of piston rods 4234 arranged on the second pushing plate 4233, the piston rods 4234 are in movable sealing connection with the injection cavities, and the third driving element 422 can drive the second pushing plate 4233 to drive the piston rods 4234 to ascend and descend in the injection cavities to perform suction and discharge actions.

[0184] Specifically, the second injection member 4231 is roughly in the shape of a cuboid, which is distributed along the width direction of the second mounting frame 421, so that the injection cavities therein can be distributed in the width direction of the extraction assembly 423 to correspond to the positions of the multi-union detection reagent strip 20. The second injection member 4231 also has a certain height to ensure that the space of the injection cavities is large enough, so that the piston rods 4234 can generate a large enough suction and discharge force when moving in the injection cavities.

[0185] The second loading head 4232 is in interference fit with the tip head 24, so as to ensure the stability of the tip head 24 loaded on the second loading head 4232, and facilitate the tip head 24 to be removed by pushing. When the first driving element 411 drives the second mounting frame 421 to lower the extraction assembly 423, the tip head 24 loaded on the second loading head 4232 can break the corresponding sealing film on the multi-union detection reagent strip 20. The second loading head 4232 is in communication with the syringe cavity, so that the syringe cavity is in communication with the tip head 24, and when the piston rod 4234 is pushed to rise and fall in the syringe cavity, the tip head 24 can be used to suck and spit the sample.

[0186] The transmission shaft of the third driving element 422 extends downward through the top of the second mounting frame 421 and the second pushing plate 4233. A fixing member in thread connection with the transmission shaft can be arranged on the transmission shaft, and the second pushing plate 4233 is fixed on the fixing member. When the transmission shaft of the third driving element 422 acts, the second pushing plate 4233 can be driven to rise and fall by the fixing member, so as to realize the rising and falling of the piston rod 4234.

[0187] Alternatively, a threaded hole can be arranged on the second pushing plate 4233, and a thread can be arranged on the transmission shaft of the third driving element 422. The transmission shaft is in thread connection with the second pushing plate 4233. In this way, the connection stability between the transmission shaft and the second pushing plate 4233 can be ensured, and the third driving element 422 can also drive the second pushing plate 4233 to rise and fall by thread driving.

[0188] In the embodiment, the end of the piston rod 4234 in the syringe cavity can be sealed with a sealing ring (such as a rubber ring or a plastic ring, etc.). When the piston rod 4234 is driven upward by the second pushing plate 4233 to rise in the syringe cavity, a negative pressure is generated in the syringe cavity to make the tip head 24 suck the sample. When the piston rod 4234 is pushed downward by the second pushing plate 4233 to fall in the syringe cavity, a positive pressure is generated in the syringe cavity to make the tip head 24 spit the sample.

[0189] Further, in order to ensure that the second pushing plate 4233 stably drives the piston rod 4234 to rise and fall, a slide rail extending in the vertical direction is arranged on the syringe 4231, and a slide block adapted to the slide rail is arranged on the second pushing plate 4233. The slide rail and the slide block are matched to realize the stable movement of the second pushing plate 4233 relative to the second mounting frame 421, and ensure the stable driving of the piston rod 4234. The slide rail and the slide block are two groups, which are respectively arranged on the left and right sides of the sample extraction mechanism 42, to further ensure the stable rising and falling of the second pushing plate 4233.

[0190] More, the photoelectric switch can be arranged on the top of the second mounting frame 421, and the baffle can be arranged on the corresponding side of the second push plate 4233. When the second push plate 4233 drives the baffle to move to the photoelectric switch and the photoelectric switch is disconnected, it indicates that the second push plate 4233 has moved to the set height, that is, the piston rod 4234 has been reset. At this time, the power supply of the third driving element 422 can be disconnected to avoid damage of the third driving element 422 due to overloading.

[0191] Please combine FIG. 9 and FIG. 13. In the embodiment of the present application, the plurality of syringe cavities are uniformly distributed along the length direction of the syringe device 4231; the plurality of second loading heads 4232 are uniformly distributed along the length direction of the syringe device 4231; and the plurality of piston rods 4234 are uniformly distributed along the length direction of the second push plate 4233. That is, the plurality of piston rods 4234, the plurality of syringe cavities and the plurality of piston rods 4234 correspond one by one, thereby realizing multi-channel parallel processing of the plurality of multi-union detection reagent strips 20.

[0192] Please continue to refer to FIG. 13. Further, the sample extraction mechanism 42 further comprises:

[0193] The push rod 4235 is arranged in the syringe device 4231 in a liftable manner, and the top end of the push rod 4235 is spaced apart from the second push plate 4233;

[0194] The elastic element 4236 is arranged in the syringe device 4231 and surrounds the push rod 4235. When the push rod 4235 is lifted or lowered relative to the syringe device 4231, the elastic element 4236 is simultaneously stretched or compressed; and

[0195] The separation plate 4237 is arranged at the bottom of the syringe device 4231, the second loading head 4232 passes through the separation plate 4237, the bottom end of the push rod 4235 is connected with the separation plate 4237, and the push rod 4235 can drive the separation plate 4237 to be lifted or lowered relative to the second loading head 4232.

[0196] In the embodiment of the present application, the separation plate 4237 is provided with a through hole, and the size of the through hole is smaller than the size of the connection between the tip head 24 and the second loading head 4232. Therefore, the tip head 24 loaded on the second loading head 4232 can be removed through the arrangement of the separation plate 4237.

[0197] Specifically, since the top end of the push rod 4235 is spaced apart from the second push plate 4233, when the second push plate 4233 is pushed downward by the third driving element 422 to a certain height to contact the top end of the push rod 4235, the second push plate 4233 pushes the push rod 4235 to descend in the syringe device 4231, thereby pushing the separation plate 4237 at the bottom of the syringe device 4231 to descend and abut against the tip head 24, so as to push the tip head 24 to separate from the second loading head 4232.

[0198] After the separation of the tip head 24 is completed, the third driving element 422 stops driving, and the elastic element 4236 is stretched to generate an upward pushing force on the pushing rod 4235, so as to drive the separation plate 4237 to reset. The compression of the elastic element 4236 can provide a certain buffering force for the downward movement of the pushing rod 4235, so as to avoid that the tip head 24 is damaged due to too fast downward movement of the pushing rod 4235, or that the tip head 24 is pressed on the multi-association reagent strip 20 to cause the multi-association reagent strip 20 to be offset or shaken.

[0199] In the embodiment of the present application, the pushing rod 4235 and the elastic element 4236 are two, which are respectively arranged on the two sides of the syringe element 4231, so as to ensure that the pushing rod 4235 stably pushes the separation plate 4237, and further ensure the separation effect of the tip head 24 and the stable reset of the elastic element 4236 on the separation plate 4237.

[0200] Exemplarily, the process of the sample extraction mechanism 42 sucking and spitting the sample (and transferring / mixing the reagent) is as follows:

[0201] The reaction chamber assembly 30 drives the multi-association reagent strip 20 to move to the corresponding position, the first driving element 411 drives the second mounting frame 421 to descend, and the second mounting head 4232 is fixedly connected with the tip head 24 on the multi-association reagent strip 20.

[0202] After the loading of the tip head 24 is completed, the reaction chamber assembly 30 drives the multi-association reagent strip 20 to move, so that the tip head 24 moves above the sample hole 23, the third driving element 422 drives the piston rod 4234 to descend in the syringe cavity to a certain height or to the lowest point, then the first driving element 411 drives the second mounting frame 421 to descend to a certain height, so that the tip of the tip head 24 extends into the sample, the third driving element 422 drives the piston rod 4234 to ascend to suck the sample through the tip head 24. Then, the first driving element 411 drives the second mounting frame 421 to ascend, so that the tip head 24 is separated from the sample liquid surface, the reaction chamber assembly 30 drives the multi-association reagent strip 20 to move, so that the tip head 24 with the sample is moved above the target hole position.

[0203] The first driving element 411 drives the second mounting frame 421 to descend, so that the tip head 24 with the sample is lowered, and the tip of the tip head 24 extends below the liquid surface of the reagent, the third driving element 422 drives the piston rod 4234 to descend, so that the sample in the tip head 24 is injected into the reagent. Then, the first driving element 411 drives the second mounting frame 421 to ascend, so that the tip head 24 is separated from the reagent, and the third driving element 422 drives the piston rod 4234 to ascend to the original position, so as to realize the sucking and spitting transfer of the sample, and then the tip head 24 is retreated into the tip head hole.

[0204] The reagent transfer process is the same as the sample transfer process, which will not be described here.

[0205] If multiple pipetting is required, the tip head 24 is repeatedly loaded and the actions of suction and injection are repeated. In addition, the sample extraction mechanism 42 can also be used for mixing reagents. The third driving element 422 drives the piston rod 4234 to repeatedly rise and fall in the syringe cavity, and the tip head 24 repeatedly sucks and discharges under the liquid surface of the reagent, so that the reagents or samples required for reaction are fully mixed and reacted.

[0206] Referring to FIGS. 8, 10 and 11, the gantry 41 is further provided with a moving space 412, the transmission shaft of the first driving element 411 passes through the moving space 412, the transmission shaft is sleeved with a transmission plate 413, the transmission shaft is provided with threads, and the transmission plate 413 is provided with screw holes. Therefore, when the transmission shaft moves, the transmission plate 413 can be synchronously lifted and lowered in the moving space 412 through thread transmission.

[0207] In addition, the first mounting frame 431 is provided with a first connecting portion on the side facing the gantry 41, the first connecting portion is formed by extending the vertical extension plate of the first mounting frame 431 toward the gantry 41, the second mounting frame 421 is provided with a second connecting portion on the side facing the gantry 41, the second connecting portion is formed by extending the vertical extension plate of the second mounting frame 421 toward the gantry 41, and the first connecting portion and the second connecting portion are connected with the transmission plate 413 through fasteners (such as screws). Therefore, when the transmission plate 413 is lifted and lowered with the transmission shaft of the first driving element 411, the second mounting frame 421 and the first mounting frame 431 can be lifted and lowered, that is, the sample extraction mechanism 42 and the sample pretreatment mechanism 43 can be lifted and lowered on the gantry 41.

[0208] Referring to FIGS. 2, 3 and 14, the reaction chamber assembly 30 further includes:

[0209] a guide rail 31 provided on the bottom plate of the mounting frame 10;

[0210] a reaction chamber body 32 provided on the guide rail 31, the bottom of the reaction chamber body 32 is provided with a guide block in sliding connection with the guide rail 31, and the reaction chamber body 32 is provided with a plurality of evenly spaced accommodation grooves 33 for loading a plurality of test reagent strips 20, the accommodation grooves 33 extend along the length direction of the reaction chamber body 32;

[0211] a fourth driving element 34 provided on the bottom plate of the mounting frame 10 and located at the rear end of the guide rail 31, and a first driving pulley is provided on the transmission shaft of the fourth driving element 34;

[0212] The mounting seat 35 is arranged on the bottom plate of the mounting frame 10 and located at the front end of the guide rail 31, and the first driven pulley 36 is arranged on the mounting seat 35, and the first driving pulley is in transmission connection with the first driven pulley 36 through the belt.

[0213] The first synchronous belt pressing plate is arranged on one side of the reaction chamber body 32 and connected with the belt.

[0214] Specifically, the guide rail 31 extends along the length direction of the mounting frame 10, and the sliding connection of the guide rail 31 and the guide block enables the reaction chamber assembly 30 to move stably along the length direction of the mounting frame 10. The shape of the accommodating groove 33 is matched with the shape of the multi-parallel detection reagent strip 20, so that the multi-parallel detection reagent strip 20 can be stably loaded on the reaction chamber assembly 30, and the stability in the moving process and the pretreatment process is maintained, the deviation and shaking are avoided, and the leakage of reagents from the multi-parallel detection reagent strip 20 is avoided.

[0215] The fourth driving element 34 is located at the rear end of the mounting frame 10, and the mounting seat 35 is located at the front end of the mounting frame 10, so that the connection between the two can cover the length direction of the mounting frame 10, so that the moving distance of the reaction chamber assembly 30 in the mounting frame 10 can be long enough to better cooperate with the movement of the multi-channel multi-parallel detection parallel pretreatment device 40.

[0216] The transmission efficiency of the transmission structure composed of the first driving pulley, the belt, the first synchronous belt pressing plate and the first driven pulley 36 is high, and the structure is simple and has sufficient power. Combined with the arrangement of the guide rail 31, the stable and rapid movement of the reaction chamber assembly 30 in the mounting frame 10 can be ensured, and the movement efficiency of the reaction assembly is improved.

[0217] Furthermore, a photoelectric switch for detecting the position of the reaction chamber body 32 in real time can be arranged on the bottom plate of the mounting frame 10, and a baffle can be arranged on the reaction chamber body 32. When the reaction chamber body 32 drives the baffle to move to the corresponding position, the baffle reaches the photoelectric switch and causes the photoelectric switch to be disconnected, which indicates that the reaction chamber assembly 30 has reached the set position. At this time, the power supply of the fourth driving element 34 can be disconnected, so as to avoid overloading and failure caused by continuous work of the fourth driving element 34, and save power consumption.

[0218] In addition, a heating module is further arranged at the bottom of the reaction chamber body 32, and the heating temperature of the heating module can be constant at human body temperature, i.e. 37℃. The temperature in the reaction chamber body 32 is constant within the preset value range, so that the reagents in the multi-parallel detection reagent strip 20 meet the temperature conditions of chemiluminescence determination.

[0219] Please refer to FIG. 2, FIG. 15 and FIG. 16, further, the PMT assembly 60 comprises:

[0220] A mounting bracket 61 is arranged on the bottom plate of the mounting frame 10;

[0221] A third mounting bracket 62 is arranged on the mounting bracket 61;

[0222] A fourth mounting bracket 63 is arranged at the bottom of the third mounting bracket 62;

[0223] A PMT module 64 is arranged on the fourth mounting bracket 63;

[0224] A fifth driving element 65 is arranged at the top of the third mounting bracket 62 and is in driving connection with the fourth mounting bracket 63, and the fifth driving element 65 can drive the fourth mounting bracket 63 to move up and down to drive the PMT module 64 to move up and down;

[0225] A sixth driving element 66 and a second driven pulley 67 are respectively arranged at the top of the two sides of the mounting bracket 61, the transmission shaft of the sixth driving element 66 is provided with a second driving pulley, and the second driving pulley is in driving connection with the second driven pulley 67 through a belt; and

[0226] A second synchronous belt pressing plate 68 is arranged on the third mounting bracket 62, and the second synchronous belt pressing plate 68 is connected with the belt.

[0227] In the embodiment, the structure of the mounting bracket 61 can be similar to that of the gantry 41, which also spans the width direction of the mounting frame 10, so that the PMT module 64 can move above the reaction chamber assembly 30 to realize chemiluminescence detection. In addition, the mounting bracket 61 can also be made of metal materials, such as stainless steel, iron, aluminum and various alloys, etc., which has high strength and can improve the service life of the PMT assembly 60.

[0228] The third mounting bracket 62 is used for mounting the fifth driving element 65 to provide stable support for the fifth driving element 65, so that the fifth driving element 65 is stably arranged at the top of the mounting bracket 61. The fourth mounting bracket 63 is used for mounting the PMT module 64, which is in driving connection with the fifth driving element 65, so that the PMT module 64 can move up and down under the driving of the fifth driving element 65. The third mounting bracket 62 is in driving connection with the belt, so that the fourth mounting bracket 63 and the PMT module 64 thereon can move horizontally, and the PMT module 64 can move up, down, left and right on the mounting bracket 61 through the combination of the fifth driving element 65 and the sixth driving element 66.

[0229] In this embodiment, the fifth driving element 65 can be a lead screw motor. The fifth driving element 65, located on the top of the mounting bracket 61, drives the fourth mounting bracket 63 to rise and fall, thereby driving the PMT module 64 to rise and fall. This allows the PMT assembly 60 to move closer to or further away from the multi-test strip 20. The lead screw motor has high motion precision, making the position adjustment of the PMT module 64 more accurate and stable. This enables the PMT assembly 60 to accurately and stably detect the luminescence value of the detection position on the multi-test strip 20.

[0230] The sixth drive element 66 can be a stepper motor, which is located on the top side of the mounting bracket 61 (e.g., the right side), while the second driven pulley 67 is located on the top other side of the mounting bracket 61 (e.g., the left side), so that the connection between the two can cover the length direction of the mounting bracket 61, thereby enabling the movement of the PMT module 64 on the mounting bracket 61 to cover the width range of the mounting frame 10.

[0231] The transmission structure consisting of the second active pulley, belt, second synchronous belt pressure plate 68 and second driven pulley 67 has high transmission efficiency, simple structure and sufficient power. The belt can increase the moving speed of PMT module 64 and thus improve detection efficiency, so that PMT component 60 can move and switch quickly between the various multi-unit test strips 20 in reaction chamber component 30 to perform luminescence value detection respectively.

[0232] Please refer to Figures 2, 15, and 16. Furthermore, the membrane breaking assembly 50 includes:

[0233] The seventh drive element 51 is located at the top of the mounting bracket 61;

[0234] A fifth mounting bracket 52 is mounted on the mounting bracket 61 and located below the seventh drive element 51. The fifth mounting bracket 52 is drively connected to the seventh drive element 51 and can be raised and lowered under the drive of the seventh drive element 51; and

[0235] Multiple film-breaking heads 53 are located at the bottom of the fifth mounting frame 52, and the multiple film-breaking heads 53 are evenly distributed at intervals along the length direction of the fifth mounting frame 52.

[0236] In this embodiment, the membrane breaking component 50 and the PMT component 60 share the mounting bracket 61, which improves the utilization rate of the mounting bracket 61, controls the internal volume of the device, and promotes the miniaturization of the device. The membrane breaking component 50 is located on the side of the mounting bracket 61 closer to the multi-channel multi-test parallel pretreatment device 40. This closer proximity to the multi-test reagent strip 20 shortens the movement distance of the multi-test reagent strip 20, allowing for faster membrane breaking in the common liquid area 2112 and improving the analytical efficiency of the device.

[0237] The seventh driving element 51 can be a lead screw motor. The seventh driving element 51 arranged on the top of the mounting bracket 61 drives the fifth mounting bracket 52 to lift to drive the membrane breaking head 53 to lift, so that the membrane breaking head 53 can be close to or away from the multi-association reagent strip 20, and then the sharp end of the membrane breaking head 53 breaks the sealing film and switches between different reagent holes. Moreover, the lead screw motor has high movement accuracy, and the position adjustment of the membrane breaking head 53 is more accurate and stable, so that the membrane breaking head 53 can accurately and stably break the sealing film of the common liquid area 2112, and avoid shaking and misplacement caused by pressing the multi-association reagent strip 20.

[0238] The number of the membrane breaking head 53 is the same as that of the multi-association reagent strip 20, so that all the multi-association reagent strips 20 can be broken at the same time, the processing speed is improved, and the analysis efficiency of the equipment is improved. Further, the membrane breaking head 53 can also be arranged in multiple rows, for example, the number of rows is the same as the number of reagent holes in the common liquid area 2112. In this way, the membrane breaking assembly 50 only needs to be operated once to break all the sealing films of the common liquid area 2112, the membrane breaking efficiency is improved, and the analysis efficiency of the equipment is improved.

[0239] In the embodiment of the present application, the transmission shaft of the seventh driving element 51 extends downward through the top of the fifth mounting bracket 52. A fixing member threadedly connected with the transmission shaft can be arranged on the transmission shaft, and the fifth mounting bracket 52 is fixed on the fixing member. When the transmission shaft of the seventh driving element 51 operates, the fifth mounting bracket 52 is lifted to realize the lifting of the membrane breaking head 53 through the fixing member.

[0240] Alternatively, a threaded hole can be arranged on the fifth mounting bracket 52, and a thread is arranged on the transmission shaft of the seventh driving element 51. The transmission shaft is threadedly connected with the fifth mounting bracket 52 (threaded hole). In this way, the connection stability between the two can be ensured, and the seventh driving element 51 can stably drive the fifth mounting bracket 52 to lift through the threaded driving mode.

[0241] In the embodiment of the present application, the membrane breaking head 53 and the fifth mounting bracket 52 can be detachably arranged. For example, the membrane breaking head 53 is arranged on the fifth mounting bracket 52 through a screw. The stability of the membrane breaking head 53 on the fifth mounting bracket 52 can be ensured, and the membrane breaking head 53 is convenient to disassemble and assemble. When the membrane breaking head 53 is damaged, the membrane breaking head 53 is convenient to replace.

[0242] Further, in order to stably drive the fifth mounting bracket 52 to lift by the seventh driving element 51, a slide rail extending in the vertical direction can be arranged on the mounting bracket 61, and a slide block matched with the slide rail can be arranged on the fifth mounting bracket 52. The stable movement of the fifth mounting bracket 52 relative to the mounting bracket 61 is realized through the cooperation of the slide rail and the slide block. The slide rail and the slide block are two groups and are arranged on the left and right sides of the above two groups, respectively. The stable lifting of the fifth mounting bracket 52 is further ensured.

[0243] Further, a photoelectric switch can be arranged on the top of the mounting bracket 61, and a baffle can be arranged on the corresponding side of the fifth mounting bracket 52. When the fifth mounting bracket 52 moves the baffle to the photoelectric switch, the photoelectric switch is turned off, indicating that the fifth mounting bracket 52 has moved to the set height reset position. At this time, the power supply of the seventh driving element 51 can be turned off to avoid overloading and damage of the seventh driving element 51, and to save power consumption.

[0244] Further, the multi-channel multi-association POCT full-automatic chemiluminescence equipment 100 can further include control modules, electrical modules, display modules, image acquisition modules, heat dissipation modules, and alarm modules. The control modules are electrically connected with the electrical modules, the display modules, the image acquisition modules, the heat dissipation modules, and the alarm modules. The electrical modules are also electrically connected with the display modules, the image acquisition modules, the heat dissipation modules, and the alarm modules.

[0245] For example, the electrical modules can be used to provide power support for the entire equipment, and the control modules can be used to control the operation of the equipment, such as controlling the opening and closing of the driving elements, the opening and closing of the heating modules, the display of the display modules, and the image acquisition and conversion of the image acquisition modules. The display modules can be used to display the running parameters and project analysis results of the equipment. The image acquisition modules can be used to take pictures and monitor the pre-processing work of the multi-channel multi-association POCT parallel pre-processing device 40. When an abnormality is monitored, the alarm module (such as an audible and visual alarm or a display alarm) can be controlled by the control module to issue a corresponding warning. The heat dissipation modules can be used to dissipate heat from the equipment to avoid overheating and affect normal operation.

[0246] The control modules, the electrical modules, the display modules, the image acquisition modules, the heat dissipation modules, and the alarm modules are not related to the application points of the present application, and therefore will not be described in detail here. Only their connection relationship and basic functions will be described. If there is any ambiguity, those skilled in the art can refer to the structure, position, and function of the control modules, the electrical modules, the display modules, the image acquisition modules, the heat dissipation modules, and the alarm modules in related technologies.

[0247] The above is only an optional embodiment of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
