Since the reagent card is inserted into the card slot incubation position, the end of the reagent card is less exposed outside, which is not convenient for the staff to take out the incubated reagent card from the card slot incubation position. Summary of the Invention
[0005] In order to improve the problem that when the reagent card is inserted into the card slot incubation position, the end of the reagent card is less exposed outside, which is not convenient for the staff to take out the incubated reagent card from the card slot incubation position, the present application provides an incubation device for in vitro diagnostic reagent cards.

[0007] By adopting the above technical solutions, the reagent card is inserted into the incubation groove, and the heating film heats the incubation tray to incubate the reagent card. When the incubation of the reagent card is completed, the driving member is started to push the reagent card out of the incubation groove by the driving member, so that it is convenient for the staff to take out the reagent card from the incubation groove.

When the incubation slot is in a free state, the control component controls the indicator light to turn on. When the reagent card is inserted into the incubation slot, the control component controls the indicator light to turn off. When a failure occurs in the incubation tray, it is convenient for the staff to distinguish whether there is a reagent card in the incubation slot according to the prompt of the indicator light during inspection.
[0010] Preferably, an installation groove 1 is formed on the inner bottom surface of the incubation slot. The control component includes a fixed contact 1 arranged in the installation groove 1.

When the reagent card is inserted into the free incubation slot, the reagent card pushes the rotating piece to rotate upward, so that the moving contact is separated from the fixed contact 1, and the circuit of the indicator light is in an open state, thereby turning off the indicator light.
[0012] Preferably, a spring is fixed on the top surface of the rotating piece, and the top end of the spring is fixed on the inner top surface of the installation groove 2.

When the incomplete gear disengages from the first rack, the incomplete gear meshes with the second rack, the incomplete gear drives the second rack to move, the second rack drives the push block to move, so that the push block moves to the initial position, facilitating the insertion of the reagent card into the incubation tank.
[0016] Preferably, a plurality of timers are arranged on the bottom surface of the incubation tray, the plurality of timers correspond to the plurality of incubation tanks, a plurality of controllers are arranged on the bottom surface of the incubation tray, the output end of the timer is electrically connected to the control end of the controller, the output end of the controller is electrically connected to the control end of the motor, and a control member for controlling the opening and closing of the timer is arranged on the incubation tray.
[0017] By adopting the above technical solution, when the reagent card is inserted into the incubation tank, the control member controls the timer to start, the timer starts to time the incubation time of the reagent card, and transmits the time signal to the controller.

[0019] By adopting the above technical solution, when the reagent card is inserted into the incubation tank, the reagent card pushes the rotating piece to rotate, the rotating piece drives the moving contact to rotate, so that the moving contact disengages from the fixed contact one and abuts against the fixed contact two, further forming a loop in the loop of the timer, and the timer times the incubation time of the reagent card.
[0020] Preferably, grooves are formed on both side surfaces of the push block, and moving wheels are rotatably installed in the grooves, and the moving wheels can roll on the inner side surface of the incubation tank.
[0021] By adopting the above technical solution, moving wheels are rotatably installed on both side surfaces of the pushing block.

When the incomplete gear disengages from the first rack, the incomplete gear meshes with the second rack, and the incomplete gear drives the second rack to move, and the second rack drives the pushing block to move, so that the pushing block moves to the initial position, facilitating the insertion of the reagent card into the incubation tank; 2. When the reagent card is inserted into the incubation tank, the control member controls the timer to start, so that the timer starts to time the incubation time of the reagent card and transmits the time signal to the controller.

Detailed implementation manners
[0027] The following further elaborates on this application in conjunction with the attached Figures 1-3 drawings for a more detailed description.
[0028] An embodiment of this application discloses an incubation device for in vitro diagnostic reagent cards.
[0029] Referring to Figure 1 , an incubation device for in vitro diagnostic reagent cards includes an incubation tray 11. A heating film 12 is disposed on the top surface of the incubation tray 11. A heating film pressing plate 13 is disposed on the top surface of the heating film 12. The heating film pressing plate 13 is fixedly connected to the incubation tray 11 by bolts. A plurality of incubation grooves 14 for inserting reagent cards are formed on both side surfaces of the incubation tray 11. The plurality of incubation grooves 14 are equally spaced along the length direction of the incubation tray 11.
[0030] Insert the reagent cards to be incubated into the plurality of incubation grooves 14 respectively, so that the heating film 12 heats the incubation tray 11, and the incubation tray 11 incubates the reagent cards.
[0031] Referring to Figure 2 and Figure 3 , a plurality of indicator lights 3 are fixed on both side surfaces of the top surface of the incubation tray 11. The plurality of indicator lights 3 correspond to the plurality of incubation grooves 14. The plurality of indicator lights 3 are equally spaced along the length direction of the incubation tray 11. A mounting groove one 31 is formed on the inner bottom surface of the incubation groove 14. A fixed contact one 32 is fixed in the mounting groove one 31. A mounting groove two 33 is formed on the inner top surface of the incubation groove 14. A rotating piece 34 is rotatably mounted in the mounting groove two 33. A moving contact 38 is fixed on the rotating piece 34. The moving contact 38 can abut against the fixed contact one 32. A spring 35 is fixed on the top surface of the rotating piece 34. The top end of the spring 35 is fixed to the inner top surface of the mounting groove two 33.
[0032] Referring to Figure 3 , a plurality of circular grooves 36 are formed on both side surfaces of the top surface of the incubation tray 11. The plurality of circular grooves 36 correspond to the plurality of incubation grooves 14. A power supply 37 is fixed in the circular groove 36. One terminal of the indicator light 3 is electrically connected to one electrode of the power supply 37. The other electrode of the power supply 37 is electrically connected to the moving contact 38. The fixed contact one 32 is electrically connected to the other terminal of the indicator light 3.
[0033] When no reagent card is inserted into the incubation tank 14, the incubation tank 14 is in a vacant state. The rotating piece 34 rotates downward under the elastic force of the spring 35, so that the moving contact 38 abuts against the fixed contact one 32, thereby making the circuit in a closed state, and the indicator light 3 above the vacant incubation tank 14 lights up, facilitating the staff to find the vacant incubation tank 14. When the reagent card is inserted into the incubation tank 14, the reagent card pushes the rotating piece 34 to rotate upward, so that the moving contact 38 on the rotating piece 34 disengages from the fixed contact one 32, thereby making the indicator light 3 circuit in an open state and turning off the indicator light 3.
[0034] Refer to Figure 3 , a push block 4 is slidably arranged in the incubation tank 14. Grooves 45 are formed on both side surfaces of the push block 4, and moving wheels 46 are rotatably installed in the grooves 45. The moving wheels 46 can roll on the inner side surface of the incubation tank 14. A plurality of motors 41 are fixed on both sides of the bottom surface of the incubation tray 11. The plurality of motors 41 correspond to the plurality of incubation tanks 14. The output shafts of the motors 41 are inserted into the incubation tanks 14. Incomplete gears 42 are sleeved and fixed on the output shafts of the motors 41. Rack one 43 and rack two 44 are respectively fixed at both ends of the side surface of the push block 4 close to the incomplete gear 42. The incomplete gear 42 can mesh with the rack one 43 and the rack two 44.
[0035] When the incubation of the reagent card in the incubation tank 14 is completed, by starting the motor 41 below the corresponding incubation tank 14, the output shaft of the motor 41 drives the incomplete gear 42 to rotate. During the rotation of the incomplete gear 42, the rack one 43 is driven to move, so that the rack one 43 drives the push block 4 to move, thereby pushing the end of the reagent card away from the incomplete gear 42 out of the incubation tank 14. When the incomplete gear 42 continues to rotate, the teeth on the incomplete gear 42 disengage from the rack one 43 and mesh with the rack two 44, so that the incomplete gear 42 drives the rack two 44 to drive the push block 4 to move towards the direction close to the incomplete gear 42, and further moves the push block 4 to the initial position, facilitating the insertion of the reagent card to be incubated again.
[0036] Refer to Figure 3 , a plurality of timers 2 are fixed on both sides of the bottom surface of the incubation tray 11. The plurality of timers 2 correspond to the plurality of incubation tanks 14. A plurality of controllers 21 are fixed on both sides of the bottom surface of the incubation tray 11. The plurality of controllers 21 correspond to the plurality of timers 2. The output end of the timer 2 is electrically connected to the control end of the controller 21, and the output end of the controller 21 is electrically connected to the control end of the motor 41. A fixed contact two 22 is fixed on the inner top surface of the installation groove two 33. The moving contact 38 can be attached to the fixed contact two 22. The fixed contact two 22 is electrically connected to one of the wiring terminals of the timer 2, and the other wiring terminal of the timer 2 is electrically connected to the power supply 37.
[0037] When the reagent card is inserted into the incubation tank 14, the reagent card pushes the rotating piece 34 to rotate upward into the second installation groove 33, so that the moving contact 38 is separated from the first fixed contact 32 and abuts against the second fixed contact 22, thereby forming a circuit for the timer 2, powering on the timer 2 to start timing the incubated reagent card. The timer 2 transmits the time signal calculated for the incubation of the reagent card to the controller 21. When the time signal received by the controller 21 reaches the set time signal, the controller 21 controls the motor 41 to start, so that the output shaft of the motor 41 drives the incomplete gear 42 to rotate, the incomplete gear 42 drives the first rack 43 to rotate, the first rack 43 drives the push block 4 to move, and the push block 4 pushes the incubated reagent card out of the incubation tank 14.
[0038] The implementation principle of the in vitro diagnostic reagent card incubation device according to the embodiment of the present application is as follows: when the incubation tank 14 is in an idle state, the rotating piece 34 moves downward under the elastic force of the spring 35, the rotating piece 34 drives the moving contact 38 to move, and the moving contact 38 abuts against the first fixed contact 32, thereby turning on the indicator light 3 to prompt the staff of the position of the idle incubation tank 14, facilitating the staff to directly find the idle incubation tank 14 and insert the reagent card into the incubation tank 14.
[0039] When the staff inserts the reagent card into the incubation tank 14 below the lit indicator light 3, the reagent card pushes the rotating piece 34 to rotate, so that the moving contact 38 on the rotating piece 34 is separated from the first fixed contact 32 and abuts against the second fixed contact 22, turning off the indicator light 3 and forming a circuit for the timer 2, so that the timer 2 times the incubated reagent card. The timer 2 also transmits the calculated time signal to the controller 21. When the time signal received by the controller 21 reaches the set time signal, the controller 21 controls the motor 41 to start, the output shaft of the motor 41 drives the incomplete gear 42 to rotate, the incomplete gear 42 drives the first rack 43 to rotate, the first rack 43 drives the push block 4 to move, and the push block 4 pushes the reagent card out of the incubation tank 14, thus facilitating the staff to take out the incubated reagent card. At this time, the bottom end of the moving contact 38 abuts against the top surface of the push block 4, and the output shaft of the motor 41 continues to drive the incomplete gear 42 to rotate, so that the incomplete gear 42 disengages from the first rack 43 and meshes with the second rack 44, the incomplete gear 42 drives the second rack 44 to move, the second rack 44 drives the push block 4 to move in the direction close to the incomplete gear 42. When the push block 4 disengages from the moving contact 38, the rotating piece 34 drives the moving contact 38 to rotate downward under the elastic force of the spring 35, so that the moving contact 38 abuts against the first fixed contact 32, forming a circuit for the indicator light 3, and the indicator light 3 lights up, thereby prompting the staff that the incubation tank 14 from which the reagent card is taken out is in an idle state.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
