Telescopic assembly 301 moves along the length direction of push card channel 101, and also extrudes sealing sheet 201, so that sealing sheet 201 is separated from reagent card 7, thereby reducing the abrasion of sealing sheet 201, improving the oxidation resistance of sealing sheet 201, and also being beneficial to prolonging the service life of sealing sheet 201.

[0044] Specifically, the length direction of push card channel 101 is shown as arrow A in Figure 1 , and the width direction of push card channel 101 is shown as arrow B in Figure 1 .

[0045] It should be noted that the number of push card channels 101 of base 1 is not limited in the embodiment of the utility model, and one, two or more than two can be selected and arranged according to needs. Exemplarily, as shown in Figure 2 , in order to improve the number of reagent cards 7, four push card channels 101 can be arranged.

[0047] Further, in one embodiment, as shown in Figure 3As shown, the sealing mechanism 2 further comprises at least one elastic member 202 and at least one pressing plate 203. One end of the elastic member 202 is connected with the sealing plate 201, the other end is connected with the machine base 1, and can extend and retract along the width direction of the push card channel 101. One end of the pressing plate 203 is connected with the push card channel 101, and the other end extends to above the sealing plate 201 and abuts against the sealing plate 201. By the elastic force of the elastic member 202, the sealing plate 201 can be kept sealing the push card window. After the push card is completed, the extension and retraction assembly 301 is driven back by the driving assembly 302, and the sealing plate 201 is reset under the action of the elastic member 202. By the pressing plate 203, the sealing plate 201 can be pressed and held, and the stability of the sealing plate 201 is ensured.

[0048] It should be noted that the structure of the elastic member 202 is not limited in the embodiments of the utility model, and any existing structure can be selected as needed, for example, the elastic member 202 can be a spring. In addition, the number of the elastic member 202 and the pressing plate 203 is not limited.

[0049] In one embodiment, as shown in the drawings, the push card window is provided with a mounting groove at opposite ends, and the elastic member 202 is provided in pairs and arranged in the mounting groove, and the pair of elastic members 202 are respectively located at opposite ends of the sealing plate 201. By mounting the pair of elastic members 202 in the mounting groove, the elastic member 202 can smoothly extend and retract along the width direction of the push card channel 101. The pair of elastic members 202 are respectively located at opposite ends of the sealing plate 201, which is beneficial to improve the extension and retraction stability of the sealing plate 201. Figure 3 In addition, the pressing plate 203 can be provided in three, located above opposite ends of the sealing plate 201 and above the middle region, to press the sealing plate 201.

[0050] In one embodiment, as shown in the drawings, the extension and retraction assembly 301 comprises an electromagnetic plate 3011 and an extension and retraction rod 3012 corresponding to the push card channel 101. The electromagnetic plate 3011 is arranged between the machine base 1 and the pushing mechanism 3, and is used to control the extension and retraction of the extension and retraction rod 3012. The pushing mechanism 3 can drive the electromagnetic plate 3011 to move along the length direction of the push card channel 101, and the extension and retraction rod 3012 is movably arranged on the top surface of the electromagnetic plate 3011. The extension and retraction of the extension and retraction rod 3012 is controlled by the electromagnetic plate 3011, which is simple in structure and convenient to use.

[0051] Figure 4

[0052] ​​It should be noted that the electromagnetic plate 3011 can be selected to be one, and simultaneously control the extension and retraction of the plurality of telescopic rods 3012, so as to realize the simultaneous pushing out of the plurality of reagent cards 7, and improve the card output efficiency. The electromagnetic plate 3011 can also be provided in plurality, and be provided in one-to-one correspondence with the plurality of telescopic rods 3012, and the electromagnetic plate 3011 of each card pushing channel 101 controls the extension and retraction of the corresponding telescopic rod 3012, so as to realize the fine control of the card output.

[0053] For example, when one or more card pushing channels 101 need to push out the reagent card 7, the electromagnetic plate 3011 corresponding to the card pushing channel 101 is powered on, the corresponding telescopic rod 3012 extends upward and deeply into the card pushing groove 601, and the driving assembly 302 drives the telescopic rod 3012 to move along the card pushing channel 101, so as to push out the reagent card 7. The telescopic rod 3012 which is not extended does not contact the reagent card 7, and thus the reagent card 7 will not be pushed out. After the electromagnetic plate 3011 is powered off, the telescopic rod 3012 retracts and leaves the card pushing groove 601.

[0054] It should be noted that the structure of the driving assembly 302 is not limited in the embodiment of the utility model, and any existing structure can be selected as needed.

[0055] In one embodiment, as shown in Figure 1 and Figure 4 The driving assembly 302 includes a driving piece 3021 and a transmission piece 3022, the driving piece 3021 is connected with the transmission piece 3022, and the electromagnetic plate 3011 is connected with the transmission piece 3022. When the card needs to be pushed, the electromagnetic plate 3011 controls the telescopic rod 3012 to extend and insert into the rear end of the reagent card box 6, and then the driving piece 3021 drives the transmission piece 3022, and the transmission piece 3022 drives the electromagnetic plate 3011 to move along the length direction of the card pushing channel 101, so as to push out the reagent card 7. The structure is simple, the use cost is low, and it is beneficial to popularization.

[0056] Further, in one embodiment, the reagent card pushing device further includes a sliding seat 4, the top of the sliding seat 4 is provided with a sliding rail, the bottom of the electromagnetic plate 3011 is provided with a sliding block, the sliding block is slidably connected with the sliding rail, the transmission piece 3022 is a conveying belt, and the conveying belt is fixedly connected with the electromagnetic plate 3011. The driving piece 3021 can adopt a motor. The conveying belt can drive the electromagnetic plate 3011 to move along the length direction of the card pushing channel 101, and at the same time, the sliding block at the bottom of the electromagnetic plate 3011 slides along the sliding rail, that is, the sliding rail and the sliding block are used to realize the guiding effect of the electromagnetic plate 3011, so as to improve the movement stability of the electromagnetic plate 3011, and facilitate the telescopic rod 3012 to push the reagent card 7 to smoothly output the card.

[0057] Specifically, a plurality of connecting plates can be further arranged between the base 1 and the sliding seat 4, so as to be fixed as a whole, so as to improve the overall structural stability of the reagent card pushing device.

[0058] Furthermore, in one embodiment, such as Figure 4 As shown, the slide 4 is also provided with a zero-point optocoupler 8, and the electromagnetic plate 3011 is provided with a corresponding sensing sheet 9. When the sensing sheet 9 interacts with the zero-point optocoupler 8, the level of the zero-point optocoupler 8 changes, and the output signal is fed back to the electromagnetic plate 3011 to reach the initial position, that is, the starting position of pushing the reagent card 7.

[0059] In other embodiments, the drive assembly 302 may also be selected from other conventional structures, such as a motor and transmission chain structure, a cylinder and push rod structure, etc.

[0060] In one embodiment, such as Figure 2 As shown, a displacement sensor 5 is provided at the rear end of the card push channel 101. The displacement sensor 5 is used to detect when the reagent card 7 is dispensing into position. The displacement sensor 5 is electrically connected to the drive assembly 302. The displacement sensor 5 can detect when the reagent card 7 in the reagent card box 6 is dispensing into position, and control the drive assembly 302 to stop running after the reagent card 7 is dispensing into position.

[0061] Furthermore, in one embodiment, the displacement sensor 5 is a microswitch. The microswitch has an arc-shaped contact and is located above the rear end of the card push channel 101. When the reagent card 7 contacts the microswitch, the microswitch is triggered and sends a position signal to realize the position detection of the reagent card 7. The arc-shaped contact of the microswitch makes contact with the reagent card 7, resulting in relatively low resistance to the reagent card 7 and improving the smoothness of the reagent card 7's movement.

[0062] It is understandable that the displacement sensor 5 can also be selected from other conventional displacement sensors such as laser sensors as needed.

[0063] According to an embodiment of this utility model, another aspect provides a medical analysis device, mainly comprising: at least one reagent card holder 6 and a reagent card pushing device. Each reagent card holder 6 has multiple reagent cards 7 stacked inside, and a card pushing slot 601 is provided at the bottom. The reagent card holders 6 are installed one-to-one on the card pushing channel 101 of the reagent card pushing device.

[0064] Because medical analytical equipment includes a reagent card pushing device, it has the same effect as the reagent card pushing device, namely, using a sealing plate 201 to seal the pushing window, providing a good seal and preventing the reagent card 7 inside the reagent card holder 6 from getting damp. When the reagent card 7 needs to be used, the telescopic component 301 of the pushing mechanism 3 first extends into the pushing slot 601 and abuts against the rear end of the reagent card 7. Then, the drive component 302 drives the telescopic component 301 to move along the length of the pushing channel 101, pushing the reagent card 7 out of the reagent card holder 6. While the telescopic component 301 moves along the length of the pushing channel 101, it also squeezes the sealing plate 201, causing the sealing plate 201 to separate from the reagent card 7, thereby reducing the wear of the sealing plate 201, improving the oxidation resistance of the sealing plate 201, and also helping to extend the service life of the sealing plate 201.

[0065] Specifically, such as Figure 5 As shown, the bottom of the reagent card holder 6 has a push-card groove 601 along its length. A telescopic rod 3012 extends into the push-card groove 601 and abuts against the rear end of the reagent card 7, pushing the reagent card 7 out along the push-card groove 601. A handle 602 is also provided on one side of the reagent card holder 6, and a door 603 for entering and exiting the reagent card 7 is provided on the opposite side. The reagent card holder 6 is detachably installed within the push-card channel 101. The detachable installation structure can be a clip, screw, etc. Multiple reagent cards 7 are stacked vertically within the reagent card holder 6. After the bottommost reagent card 7 is pushed out, the remaining reagent cards 7 move down as a whole, initiating the next push-card process.

[0066] Specifically, medical analytical equipment includes, but is not limited to, fluorescence immunoassay analyzers.
