The detection part of the reagent card 2 is positioned in the middle of the reagent card 2, a concave detection window 21 is formed at the detection part of the reagent card 2, and the concave detection window 21 and the detection result acquisition device 12 are correspondingly arranged.

The reading device body 1 is further provided with a lifting device for lifting the detection part of the reagent card 2 to one side close to the detection result acquisition device 12. The cavity 11 deviates from its open-ended one end integrated into one piece has the lifting landslide 3, and the lifting landslide 3 cooperates with the one end that reagent card 2 got into in the cavity 11 for the reagent card 2 that the guide got into in the cavity 11 moves to the one side that is close to testing result collection system 12. When the reagent card 2 is installed in place in the cavity 11, the sidewall of the reagent card 2 close to one side of the detection result acquisition device 12 is tightly attached to the inner wall of the cavity 11, and at this time, the detection result acquisition device 12 enters the concave area of the concave detection window 21.

The reading device body 1 comprises a detection channel upper cover 14 and a detection channel lower cover 15, the detection channel upper cover 14 and the detection channel lower cover 15 are connected in a fastening mode through bolts, the cavity 11 is formed by matching the detection channel upper cover 14 and the detection channel lower cover 15, a detection result acquisition device 12 is installed on one side, close to an opening of the cavity 11, of the detection channel, and the lifting landslide 3 is integrally formed at one end, far away from the opening of the cavity 11, of the detection channel lower cover 15.

As shown in fig. 2, 3, 4 and 5, the lifting device is a lever 4, an insertion groove 41 for rotatably installing a rotation shaft of the lever 4 is formed in the middle of the length of the lower detection channel cover 15, a limit portion 42 is integrally formed at the edge position of the side wall of the upper detection channel cover 14 corresponding to the insertion groove 41, the limit portion 42 is rotatably matched with the rotation shaft of the lever 4, the rotation shaft of the lever 4 is rotatably installed on the lower detection channel cover 15 by matching the insertion groove 41 and the limit portion 42, and the rotation shaft of the lever 4 does not protrude from the side wall of the lower detection channel cover 15.

The first open opening 43 allows the rotating arm of the lever 4 to enter or leave the cavity 11, the lifting slide 3 and the rotating arm of the lever 4 far away from the opening of the cavity 11 generate a limit, so that the rotating arm of the lever 4 far away from the opening of the cavity 11 cannot completely leave the cavity 11, and a gap between one end of the lever 4 close to the opening of the cavity 11 and the side wall of the cavity 11 where the detection result acquisition device 12 is located allows the reagent card 2 to pass through. Further, in order to improve the convenience of inserting the reagent card 2 into the cavity 11, a protruding portion 44 is arranged at one end, close to the outlet of the cavity 11, of the rotating arm of the lever 4, and a lifting inclined surface 45 is arranged at one side, away from the outlet of the cavity 11, of the rotating arm of the lever 4.

Adopt this design, when reagent card 2 just got into cavity 11, lever 4 was close to the swinging boom of cavity 11 open-ended and can be forced to revolve down, and lever 4 will revolve far away from the swinging boom of cavity 11 open-ended, and when reagent card 2 butt lifting landslide 3, lever 4's both sides atress simultaneously, continuously provide ascending power for reagent card 2, until concave type detection window 21 aligns with testing result collection system 12 and peg graft each other and form the spacing of a grafting direction. At this time, the concave detection window 21 on the reagent card 2 and the detection result acquisition device 12 both assume a locking structure and can better complete data acquisition work because they are closely attached to each other.

And because two rotating arms of lever 4 and reagent card 2 contact provide the resistance for the motion of reagent card 2 relative inner chamber, help guaranteeing that concave type detection window 21 and testing result collection system 12 are in the state of hugging closely, and then help guaranteeing to accomplish data acquisition work better.

As shown in fig. 3, the horizontal insertion state: the reagent card 2 is inserted into the cavity 11 by applying a horizontal force towards the inside of the cavity 11, at this time, the protrusion 44 on the rotating arm of the lever 4 contacts with the reagent card 2 and is forced to rotate downward, and the end of the rotating arm of the lever 4 far from the opening of the cavity 11 is lifted up, so that the reagent card 2 is maintained in a stable state.

As shown in fig. 4, the lifted state: continuously apply the horizontal effort towards in the cavity 11, conflict with lifting inclined plane 45 up to 2 tip of reagent card, reagent card 2 follows the inclination on lifting inclined plane 45, continues the lifting on the slant, and 2 middle parts of reagent card continue to receive the lifting force that lever 4 provided near the bellying 44 of 11 open-ended swinging boom tip of cavity, make the stable lifting of reagent integrated circuit board.

As shown in fig. 5, the in-place state: when the end of the reagent card 2 is pushed to the top end of the lifting inclined plane 45 on the lever 4, the concave detection window 21 and the detection result acquisition device 12 are completely overlapped, and the reagent card 2 is limited by the protruding part 44 on the rotating arm of the lever 4 close to the opening of the cavity 11, so that the relative positions of the concave detection window 21 and the detection result acquisition device 12 are kept stable, and the operation steps of inserting and lifting the reagent card are completed.

To remove the reagent card 2, the user applies a pulling force which will deform the lever 4 slightly until the reagent card 2 disengages from the raised ramp 45 on the lever 4, so that the lever 4 rotates the rotating arm of the lever 4 near the opening of the cavity 11 in a direction out of the cavity 11 and releases the reagent card 2.

As shown in fig. 2, when the reagent card 2 is inserted into the cavity 11, the protrusion 44 on the lever 4 abuts against the sidewall of the reagent card 2, and at this time, the reagent card 2 does not contact the lifting inclined plane 45 on the lever 4 yet, and with the continuous insertion of the reagent card 2, because the axial position of the lever 4 to the lifting slope 3 is a gradual lifting process, according to the principle of the lever 4, the end of the rotating arm of the lever 4 where the lifting inclined plane 45 is located feeds back a vertical upward lifting force to the reagent card 2 due to the vertical downward pressure applied to the end of the rotating arm of the lever 4 where the protrusion 44 is located.

When the reagent card 2 is completely inserted into the cavity 11, the end of the reagent card 2 reaches the end of the rotating arm of the lever 4 far away from the opening of the cavity 11 through the lifting slide 3 on the lever 4, the reagent card 2 is supported by the rotating arm of the lever 4, and meanwhile, the rotating arm of the lever 4 is pressed vertically downwards by the reagent card 2 due to the extrusion of the inner wall of the cavity 11. According to the principle of the lever 4, the supporting point is a rotating shaft of the lever 4, the rotating arm of the lever 4 close to the opening of the cavity 11 is lifted, a vertical upward acting force is applied to the reagent card 2, the concave detection window 21 and the detection result acquisition device 12 are tightly attached to each other, and the lifting action after the reagent card 2 is inserted is completed.
