In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1 to 3, fig. 1 shows a schematic structural diagram of a medical analyzer according to an embodiment of the present invention, fig. 2 shows a schematic structural diagram of a photoelectric detection device according to an embodiment of the present invention, and fig. 3 shows an exploded schematic structural diagram of fig. 2. An embodiment of the utility model provides a pair of photoelectric detection device, photoelectric detection device includes: a guide block 10 and a photoelectric detection module 20. The guide block 10 is provided with a slide 11 adapted to the shape of the reagent card 40 (as shown in figure 7), the slide 11 being provided with an entrance 111 for the reagent card 40. The guide block 10 is disposed on one side of the incubation plate 30, and the inlet 111 is aligned with the discharge hole 311 of the stopper 31 of the incubation plate 30. The photoelectric detection module 20 is disposed on the guide block 10, and is configured to perform photoelectric collection processing on the display portion 41 of the reagent card 40 running inside the guide block 10.

In the photoelectric detection device, the guide block 10 is arranged at one side of the incubation disc 30, the inlet 111 is aligned with the discharge hole 311 of the block 31 of the incubation disc 30, so that when the discharge hole 311 of the block 31 of the incubation disc 30 rotates to a position aligned with the inlet 111, the rotation of the incubation disc 30 is stopped, the reagent card 40 of the block 31 is pushed into the slide 11 through the discharge hole 311 and the inlet 111, and then the photoelectric acquisition module is adopted to perform photoelectric acquisition processing on the display part 41 of the reagent card 40 running into the guide block 10, so that a detection result can be obtained. Compared with the traditional detection mode of performing photoelectric acquisition by moving the photoelectric detection module above the reagent cards 40, the method has the advantages that the reagent cards 40 which need to be subjected to photoelectric acquisition are all operated in the slide way 11, namely all the reagent cards 40 are subjected to photoelectric acquisition in the same slide way 11, and the positions of the slide ways 11 are constant, so that the detection results of the reagent cards 40 are better in consistency; in addition, photoelectric calibration of each card 31 as in the conventional art is not required, thereby improving detection efficiency.

Referring to fig. 3 to 5, in one embodiment, a window 12 corresponding to the shape of the display portion 41 is formed on the top surface of the guide block 10, and the window 12 communicates with the slide 11. The photoelectric detection module 20 is disposed on the top surface of the guide block 10, and the detection end 21 of the photoelectric detection module 20 is disposed opposite to the window 12. In this way, in the process that the reagent card 40 moves into the slide 11, when the display portion 41 moves to a position opposite to the window 12 (the position of the reagent card 40 is shown in fig. 4), the reagent card 40 stops being pushed, so that the display portion 41 is exposed through the window 12, and the detection end 21 of the photoelectric detection module 20 can perform photoelectric collection operation on the display portion 41 through the window 12. In addition, after the photoelectric collecting step of the reagent card 40 is finished, the reagent card 40 is completely pushed out from the blocking position 31 of the incubation tray 30, that is, the reagent card 40 completely enters the inside of the slide way 11, that is, the position of the reagent card 40 shown in fig. 5, when a next reagent card 40 to be tested is pushed into the slide way 11, the reagent card 40 to be tested which has been subjected to the photoelectric collecting operation in the slide way 11 can be smoothly pushed out of the slide way 11 in the process that the reagent card 40 to be tested enters the slide way 11.

Referring to fig. 2 and 3, in one embodiment, the top surface of the guide block 10 is provided with a first recess 13 corresponding to the detection end 21, and the detection end 21 is fixedly disposed in the first recess 13. Thus, the detection end 21 is fixedly disposed in the first recess 13, so that the photoelectric detection module 20 can be stably aligned and mounted on the guide block 10.

Specifically, when the first recess 13 is provided on the top surface of the guide block 10, the positioning pin 14 is provided on the bottom surface of the first recess 13, for example. Thus, in the process of installing the detection end 21 on the guide block 10, the positioning pin 14 extends into the positioning hole to position the detection end 21, so that the photoelectric detection module 20 can be stably aligned and installed on the guide block 10.

It should be noted that the "positioning pin 14" may be a part of the "guide block 10", that is, the "positioning pin 14" is integrally formed with the other part of the "guide block 10"; or a separate member separable from the rest of the guide block 10, i.e., the "positioning pin 14" may be manufactured separately and integrated with the rest of the guide block 10. In one embodiment, as shown in fig. 4 or 5, the "locating pin 14" is a part of the "guide block 10" that is integrally formed.

Referring to fig. 6 and 7, fig. 6 is a schematic structural diagram illustrating a cover 16 of a photoelectric detection device according to an embodiment of the present invention being separated. In one embodiment, the inner wall of the slideway 11 is provided with at least one resilient portion 112. The elastic portion 112 is for abutting against the reagent card 40. Specifically, the elastic portion 112 includes, but is not limited to, an elastic bead. The number of the elastic portions 112 is, for example, one, two, three or other numbers, which are not limited herein, and are set according to actual requirements. The elastic portion 112 is specifically provided on the bottom wall or the top wall of the chute 11, for example, but may be disposed on the side wall of the chute 11. Like this, when pushing reagent card 40 from hatching the inside in-process that dish 30 pushed slide 11, elastic component 112 is inconsistent with the outer wall of reagent card 40, can realize that reagent card 40 operation effect is comparatively stable, is difficult for rocking.

Of course, when the slide 11 is designed to completely match the shape of the reagent card 40 and the shape of the reagent card 40 deviates less from the standard, the operation effect is already stable when the reagent card 40 moves along the slide 11, i.e. the elastic part 112 in the above embodiment may be optionally omitted.

Referring to fig. 2, 3 and 6, in one embodiment, the guide block 10 is provided with a detachable cover 16 to facilitate the installation of the elastic portion 112 on the inner wall of the slide 11. Specifically, the window 12 is provided on the cover 16. Specifically, the first recess 13 is provided on the cover 16, for example.

Referring to fig. 2, 3 and 6, in order to make the guide block 10 have a better guiding effect on the cover 16 during the process of installing the cover 16, two positioning blocks 15 are further disposed on the guide block 10 and located at two opposite sides of the cover 16, respectively. Furthermore, two positioning blocks 15 are provided with second concave portions 151, the two second concave portions 151 are in butt communication with the first concave portion 13, and the detection end 21 is further used for being inserted and positioned in the two second concave portions 151. Specifically, the positioning pin 14 is not limited to be provided on the bottom surface of the first recess 13, and may be provided on the bottom surface of the second recess 151 as shown in fig. 3 or 6, for example. In this way, the detection end 21 is positioned by the first recess 13 and the second recess 151, respectively, and can be stably positioned on the guide block 10.

It should be noted that the "positioning block 15" may be a part of the "guide block 10", that is, the "positioning block 15" and the "other part of the guide block 10" are integrally formed; or a separate member which can be separated from the rest of the guide block 10, that is, the positioning block 15 can be manufactured separately and then combined with the rest of the guide block 10 into a whole. In one embodiment, as shown in fig. 4 or 5, the "positioning block 15" is a part of the "guide block 10" that is integrally formed.

Referring to fig. 2, 3 and 6, in one embodiment, the entrance 111 of the slideway 11 is provided with an inclined surface 1111 inclined relative to the guiding direction of the guide block 10, and the caliber size of the entrance 111 decreases along the guiding direction. Thus, in the process that the reagent card 40 enters the slide 11 through the inlet 111, the inclined surface 1111 guides the reagent card 40, and the reagent card 40 can smoothly and quickly enter the slide 11.

Referring to fig. 1 to 3, in one embodiment, the photo detection device further includes a mounting plate 50. The guide block 10 is mounted on a mounting plate 50, and the mounting plate 50 is used for mounting on a frame 60.

Referring to fig. 1 to 3 and 8, fig. 8 is a schematic structural diagram of a card kicking device 70 according to an embodiment of the present invention. In one embodiment, a medical analyzer comprises the photodetection device of any of the above embodiments, and further comprises a frame 60, an incubation tray 30, a first motor (not shown in the figures), and a kick-catch device 70. The guide block 10, the first motor and the kicking and clamping device 70 are all arranged on the frame 60. The incubation tray 30 is rotatably disposed on the frame 60, and a plurality of spaced-apart positions 31 for receiving the reagent cards 40 are disposed on the incubation tray 30. The block 31 is provided with a discharge hole 311. The first motor is used for driving the incubation tray 30 to rotate, so that the discharge hole 311 of any one position-limiting part 31 of the incubation tray 30 can be aligned with the inlet 111 of the slide 11. The kicking device 70 is used for pushing the reagent card 40 in the card position 31 which is arranged opposite to the slide way 11 into the slide way 11.

In the medical analyzer, the guide block 10 is disposed at one side of the incubation tray 30, and the inlet 111 of the slide 11 is aligned with the outlet 311 of the position lock 31 of the incubation tray 30, so that when the outlet 311 of the position lock 31 of the incubation tray 30 rotates to a position aligned with the inlet 111 of the slide 11, the rotation of the incubation tray 30 is stopped, the reagent card 40 of the position lock 31 is pushed into the slide 11 through the outlet 311 and the inlet 111 of the slide 11, and then the photoelectric collecting module is used to perform photoelectric collecting processing on the display part 41 of the reagent card 40 running into the guide block 10, so as to obtain a detection result. Compared with the traditional detection mode of performing photoelectric acquisition by moving the photoelectric detection module above the reagent cards 40, the method has the advantages that the reagent cards 40 which need to be subjected to photoelectric acquisition are all operated in the slide way 11, namely all the reagent cards 40 are subjected to photoelectric acquisition in the same slide way 11, and the positions of the slide ways 11 are constant, so that the detection results of the reagent cards 40 are better in consistency; in addition, photoelectric calibration of each card 31 as in the conventional art is not required, thereby improving detection efficiency.

Referring to fig. 1 to 3 and 8, in one embodiment, the kicking device 70 includes a pushing plate 71 and a moving assembly 72 for driving the pushing plate 71 to move along the guiding direction of the guide block 10. The moving assembly 72 is disposed on the frame 60.

Referring to fig. 1, 2 and 8, in one embodiment, the kicking device 70 further includes a first position sensor 73, a second position sensor 74 and a third position sensor 75. The first position sensor 73 is used for sensing whether the push plate 71 moves to an initial push position, the second position sensor 74 is used for sensing whether the push plate 71 moves to a complete push-out position, and the third position sensor 75 is used for sensing whether the push plate 71 moves to a photoelectric acquisition position; the first position sensor 73, the second position sensor 74 and the third position sensor 75 are electrically connected to the moving assembly 72, respectively.

Referring to fig. 1, 2 and 8, in particular, the moving assembly 72 drives the pushing plate 71 to move and also drives the baffle to move, and as an example, the baffle is connected to the pushing plate 71. The first position sensor 73 is specifically, for example, a first correlation sensor disposed on the rack 60 or the mounting 721 of the moving assembly 72. The first correlation sensor is provided with a transmitting end and a receiving end, and the transmitting end transmits the optical signal to the receiving end for receiving. Under the driving action of the moving assembly 72, when the baffle moves to the position of the first correlation sensor, the emitting light of the first correlation sensor is shielded, so that the first correlation sensor senses the baffle, namely, the position to which the pushing plate 71 moves can be obtained when the baffle is sensed, namely, whether the pushing plate 71 moves to the initial pushing position can be sensed, and when the pushing plate 71 is reset to the initial pushing position, the moving assembly 72 is controlled to stop moving continuously, so that the next reagent card 40 to be detected is pushed out.

Similarly, the second position sensor 74 is specifically, for example, a second correlation sensor disposed on the rack 60 or the mounting 721 of the moving assembly 72. The second correlation sensor is provided with a transmitting end and a receiving end, and the transmitting end transmits the optical signal to the receiving end for receiving. Under the driving action of the moving assembly 72, when the baffle moves to the position of the second correlation sensor, the emitting light of the second correlation sensor is shielded, so that the second correlation sensor senses the baffle, and the position to which the push plate 71 moves can be obtained when the baffle is sensed, namely whether the push plate 71 moves to the complete push-out position or not can be sensed. When the push plate 71 moves to the fully pushed-out position, the control moving assembly 72 stops continuing the pushing, and the control moving assembly 72 moves reversely to return the push plate 71 to the initial pushing position.

Similarly, the third position sensor 75 is specifically, for example, a third correlation sensor disposed on the rack 60 or the mounting 721 of the moving assembly 72. The third correlation sensor is provided with a transmitting end and a receiving end, and the transmitting end transmits the optical signal to the receiving end for receiving. Under the drive action of the moving assembly 72, the baffle blocks the emitted light of the third correlation sensor when moving to the position of the third correlation sensor, so that the third correlation sensor senses the baffle, and the position to which the push plate 71 moves can be acquired when sensing the baffle, i.e. whether the push plate 71 moves to the photoelectric acquisition position can be sensed. When the pushing plate 71 moves to the photoelectric collecting position, the moving assembly 72 is controlled to stop pushing, at this time, the display part 41 of the reagent card 40 is located at a position opposite to the detection end 21 of the photoelectric detection module 20, the photoelectric detection module 20 is controlled to perform photoelectric collecting operation on the reagent card 40 in the slide 11, and after the photoelectric collecting operation step of the reagent card 40 is finished, the moving assembly 72 is controlled to continue to push out the reagent card 40.

Of course, the first position sensor 73, the second position sensor 74, and the third position sensor 75 may also be sensing devices such as proximity switches, etc., as long as they can be used for sensing the position of the pushing plate 71, and are not limited in detail herein.

Referring to fig. 1, fig. 2 and fig. 8, in one embodiment, the moving assembly 72 includes a mounting frame 721, a second motor 722 disposed on the mounting frame 721, a driving wheel 723 and a driven wheel 724 rotatably disposed on the mounting frame 721, and a transmission element 725 connecting the driving wheel 723 and the driven wheel 724. The push plate 71 is connected to a transmission element 725. The second motor 722 is connected to the driving wheel 723 for driving the driving wheel 723 to rotate. When the second motor 722 drives the driving wheel 723 to rotate, the driving wheel 723 drives the transmission element 725 to move, the transmission element 725 correspondingly drives the pushing plate 71 to move, and the card kicking operation can be achieved in the moving process of the pushing plate 71. Specifically, the drive elements 725 include, but are not limited to, drive belts, drive chains, and drive cords.

Of course, it is understood that the moving assembly 72 can also be, for example, a motor screw driving manner, an air cylinder driving manner, a hydraulic cylinder driving manner, etc., and is not limited herein as long as the pushing plate 71 can be driven to move.
