Description

Technical Field

[0001] The utility model relates to the field of analyzers, and in particular to a handheld immunoassay analyzer. Background Art

[0002] A fluorescent immunoassay analyzer is an instrument that uses the fluorescent effect of fluorescent substances for detection. However, traditional fluorescent immunoassay analyzers are large in size, inconvenient to carry, have low detection accuracy, and are not convenient for outdoor operations.

[0003] The inventors have found that in the prior art, it is impossible to realize a handheld instrument that is compatible with multiple reagent cards of different sizes for testing on the basis of one card insertion hole on the same instrument. Instead, multiple card insertion holes are set on a larger instrument to realize the testing of cards of different sizes. This greatly reduces the user experience and makes the testing operation cumbersome, which reduces the advantage of the simple operation of the POCT (point-of-care testing) instrument.

[0054] The first limiting assembly 200 in this embodiment includes a first touch switch 210 , a first limiting member 220 and a second limiting member 230 .

[0055] Optionally, see Figure 5 The first touch switch 210 is used to output a signal and switch the test system of the reagent card identification module to detect the first reagent card; the first touch switch 210 is disposed on the body 100 and is disposed on a side away from the detection port 130.

[0056] The first touch switch 210 is electrically connected to the reagent card identification module.

[0057] Optionally, the first limiting member 220 is provided with a first limiting surface 223 for limiting the side surface of the first reagent card, and the second limiting member 230 is provided with a second limiting surface (not shown in the figure) for limiting the top surface of the first reagent card; the first limiting surface 223 and the second limiting surface are arranged vertically.

[0058] In this embodiment, please refer to Figure 5-Figure 6 , the first limiter 220 and the second limiter 230 are an integrally formed structure; the first limiter 220 is a spring sheet structure with elastic deformation. The first limiter 220 includes a first fixed portion 221 and an arc-shaped first spring sheet 222; the first fixed portion 221 is fixed to the bottom of the lower shell 120, the first fixed portion 221 is connected to the first spring sheet 222 at one end facing the first touch switch 210, and the top of the first fixed portion 221 vertically fixes the second limiter 230.

As the first reagent card is pushed in, the two sides of the first reagent card contact the symmetrically arranged first spring pieces 222, and the symmetrically arranged first spring pieces 222 will produce a certain elastic deformation and limit the left and right displacement of the first reagent card together; at this time, the first reagent card is limited. Push the first reagent card in until the first reagent card contacts the first touch switch 210, that is, the first reagent card is pushed in place.

[0061] S12: At the same time, the first touch switch 210 outputs a signal to the reagent card identification module, so that the test system of the reagent card identification module switches to a detection mode for detecting the first reagent card.

[0062] Of course, in other embodiments, if the space conditions of the lower shell 120 allow, the first limiting member 220 and the second limiting member 230 may also be arranged at intervals.

[0063] Of course, in other embodiments, the first limiting member 220 may also be a straight plate structure without elastic deformation.

[0064] In this embodiment, please refer to Figure 5 The four sets of integrally formed first limiting members 220 and second limiting members 230 are symmetrically arranged along the insertion direction 011 of the first reagent card.

[0065] In this embodiment, please refer to Figure 5-Figure 6 The handheld immunoassay analyzer 010 includes a second limiting component 300; the second limiting component 300 is used to limit the second reagent card.

[0066] The second limiting assembly 300 in this embodiment includes a third limiting member 330 , a fourth limiting member 340 , a fifth limiting member 350 , a second touch switch 310 and an elastic structure 320 .

The second touch switch 310 is arranged on a side close to the detection port 130 and fixed to the lower housing 120, and the second touch switch 310 is arranged close to the second end of the elastic structure 320.

[0068] Optionally, see Figure 5 The second limiting assembly 300 includes two elastic structures 320 symmetrically arranged along the detection channel 140, wherein the first end of the elastic structure 320 faces the detection channel 140 and is used to contact the side of the second reagent card, and the second end of the elastic structure 320 is used to touch the second touch switch 310.

The first guide block 323 is two inverted L-shaped limit buckle structures; the second guide block 324 is a rectangular block structure with a through hole. The first end of the guide member 321 is a rectangular block structure, and a guide surface 3211 is obliquely provided on the rectangular block structure; the second end of the guide member 321 is a rod structure; the first end of the guide member 321 is slidably connected to the first guide block 323, and the second end of the guide member 321 is slidably connected to the through hole of the second guide block 324. The elastic member 322 is sleeved on the second end of the second guide block 324 and abuts against the end surface of the second guide block 324.

[0070] The elastic member 322 is a spring.

[0071] Understandably, please refer to Figure 5 , the first step of the second reagent card operation is as follows: S21: the second reagent card is pushed in from the detection port 130, the end of the second reagent card contacts the guide surface 3211 of the two guide members 321, and the guide member 321 moves along the first guide block 323 and the second guide block 324; at the same time, the guide member 321 compresses the elastic member 322 until the guide member 321 contacts the second touch switch 310, and the second touch switch 310 outputs a signal to the reagent card identification module, so that the test system of the reagent card identification module switches to the detection mode of detecting the second reagent card. Of course, after the detection is completed, the second reagent card is pulled out, and the elastic member 322 drives the guide member 321 to reset.

[0072] Optionally, the third limiting member 330 is provided with a third limiting surface for limiting the side surface of the second reagent card, the fourth limiting member 340 is provided with a fourth limiting surface for limiting the top surface of the second reagent card, and the fifth limiting member 350 is provided with a fifth limiting surface for limiting the side surface of the second reagent card; the third limiting surface, the fourth limiting surface and the fifth limiting member 350 are vertically arranged.

[0073] In this embodiment, please refer to Figure 5 , the third limiting member 330 and the fourth limiting member 340 are arranged at intervals. The third limiting member 330 is an elastic structure 320 with elastic deformation, similar to the first elastic member 322; the end surface of the third limiting member 330 elastically contacting the second reagent card is the third limiting surface. The fourth limiting member 340 is an inverted L-shaped limiting buckle structure, and the bottom surface of the fourth limiting member 340 is the fourth limiting surface.

[0074] Of course, in other embodiments, the third limiting member 330 and the fourth limiting member 340 are an integrally formed structure, and reference is made here to the first limiting member 220 and the second limiting member 230 of the integrally formed structure.

[0075] In this embodiment, please refer to Figure 6 The fifth stopper 350 is an L-shaped stopper structure; wherein the fifth stopper 350 is connected to the first fixing portion 221 close to the detection port 130, and the fifth stopper 350 is integrally formed with the first stopper 220. Of course, in other embodiments, the fifth stopper 350 can also be provided separately.

[0076] Understandably, please refer to Figure 5 , the second step of the second reagent card operation is as follows: S22: When the second reagent card is inserted into the detection channel 140, the upper top surface of the second reagent card is limited by the lower bottom surface of the fourth limiting member 340, and the second reagent card is limited by the supporting structure 121. As the second reagent card is pushed in, the two sides of the second reagent card contact the symmetrically arranged third limiting members 330, and the symmetrically arranged third limiting members 330 will produce a certain elastic deformation and limit the left and right displacement of the second reagent card together; at this time, the second reagent card is limited. The second reagent card is pushed in continuously until the second reagent card abuts against the fifth limiting member 350, that is, the second reagent card is pushed into place.

[0077] It is worth mentioning that the symmetrical setting distance in the first limiting component 200 is smaller than the symmetrical setting distance of the second limiting component 300; that is, the symmetrical setting distance of the first limiting component 220 is smaller than the symmetrical setting distance of the third limiting component 330 and the symmetrical setting distance of the fourth limiting component 340.

[0078] Please refer to Figure 3 In this embodiment, the handheld immunoassay analyzer 010 further includes an optical detection module 400, which is slidably disposed along the detection channel 140 and is used to detect the reagent card, mainly for exciting, receiving and processing the fluorescent signal of the reagent card.

[0079] Optionally, see Figure 7 The optical detection module 400 includes a module body 410, a light source 420, a PD module 430, and four optical lenses; the module body 410 is provided with a first cavity 411 and a second cavity 412 which are vertically arranged and communicated with each other, and a first opening and a second opening 413 which are communicated with the second cavity 412. The light source 420 is arranged in the first cavity 411; the PD module 430 is arranged at the first opening, and the second opening 413 faces the reagent card.

[0080] Among them, the four optical lenses include a first optical lens 440 and three second optical lenses 450; the first optical lens 440 is tilted at the connection between the first cavity 411 and the second cavity 412; one of the second optical lenses 450 is respectively arranged in the second through cavity between the first optical lens 440 and the PD module 430; one of the second optical lenses 450 is respectively arranged in the second through cavity between the first optical lens 440 and the second opening 413; one of the second optical lenses 450 is respectively arranged in the first through cavity between the first optical lens 440 and the light source 420.

[0081] Optionally, see Figure 3 The handheld immunoassay analyzer 010 further includes a motor module 500 and a track 600 . The motor module 500 and the track 600 are arranged opposite to each other and along the detection channel 140 .

[0082] Among them, one end of the module body 410 of the optical detection module 400 is transmission-connected to the motor module 500 , and the other end is slidingly connected to the track 600 through the slider 610 .

[0083] Optionally, see Figure 3 and Figure 5 The handheld immunoassay analyzer 010 further includes a third touch switch 700 , which is mounted on the fixing plate and disposed at an end away from the detection port 130 , and is used to place the optical detection module 400 in a working zero position.

[0084] In this embodiment, the handheld immunoassay analyzer 010 includes an MCU control module 150, an algorithm processing module, a reagent card identification module and a power module; the MCU control module 150 is a control unit that controls each module to work normally and orderly; the algorithm processing module is a data processing unit; the power module supplies power to the entire handheld immunoassay analyzer 010; the reagent card identification module identifies different reagent cards and transmits them to the MCU control module 150 to switch to the corresponding test system.

[0085] The MCU control module 150 is in communication connection with the motor module 500 , so that the motor module 500 cooperates with the track 600 to transport the optical detection module 400 .

[0086] Among them, the MCU control module 150, the algorithm processing module and the optical detection module 400 are communicatively connected; the optical detection module 400 excites, receives and processes the fluorescent electrical signal of the reagent card and transmits the fluorescent electrical signal to the algorithm processing module; the algorithm processing module converts the fluorescent electrical signal into the concentration of the substance to be tested in the sample.

[0087] The working principle of the handheld immunoassay analyzer 010 proposed in this embodiment is:

[0088] First, start the button 160 switch, and enter the working interface after the power-on self-test.

[0089] Insert the reagent card into the detection port 130. Please refer to the above steps S11-S12 or S21-S22 to place the reagent card. According to the signal feedback from the first touch switch 210 or the second touch switch 310, the system will automatically identify the type of the reagent card. After selecting the test item, press button 160 to start the test.

[0090] During the whole process, the reagent card is limited and in a static state, and the motor module 500 drives the optical detection module 400 to move linearly along the track 600 from the detection port 130 until the optical detection module 400 touches the third touch switch 700, and the touch switch feedback signal makes the optical detection module 400 in the working zero position.

[0091] Then, when the motor module 500 drives the optical detection module 400 to move toward the detection port 130 and reaches the effective signal area of ​​the reagent card, the optical detection module 400 excites, receives and processes the fluorescent electrical signal of the reagent card, and then quickly transmits it to the MCU control module 150. After algorithm processing, the detection result can be displayed on the LCD screen 170. At this time, the optical detection module 400 also resets to the starting position, and the reagent card is taken out to complete the detection operation. Repeat the above actions to carry out the next detection work.

[0092] At the same time, a single test of the handheld immunoassay analyzer 010 takes about 4-8 seconds, which greatly saves the user's waiting time for test results, improves work efficiency and reduces costs.
