The bracket 10 is provided with a first movement channel 11 and a second movement channel 12. The first movement path 11 communicates with the second movement path 12. The first sensor 21 is provided at the front end of the first moving path 11 for sensing whether the reagent card 50 is inserted into the first moving path 11. The first driving assembly 30 is disposed on the support 10, and the first driving assembly 30 drives the reagent card 50 to travel to the tail end of the first moving channel 11 and enter the second moving channel 12 after the reagent card 50 enters the first moving channel 11. A second drive assembly 40 is provided on the support 10, the second drive assembly 40 comprising a pusher 41 projecting into the second movement channel 12. The pushing member 41 is configured to abut against a front end surface of the reagent card 50, and the pushing member 41 can move along the second movement path 12, so that the reagent card 50 entering the second movement path 12 is pushed out to the incubation area. The controller is electrically connected to the first sensor 21, the first driving component 30 and the second driving component 40, respectively.

In the card feeding device, when the card feeding operation is performed, the reagent card 50 is inserted into the first moving channel 11, the first sensor 21 can sense that the reagent card 50 is inserted into the first moving channel 11, the controller correspondingly controls the first driving component 30 to act, and the first driving component 30 drives the reagent card 50 to move to the tail end of the first moving channel 11 and enter the second moving channel 12; in addition, the controller also controls the second driving assembly 40 to act, and the pushing member 41 of the second driving assembly 40 moves along the second movement channel 12, so that the reagent card 50 inside the second movement channel 12 is pushed out to the incubation area. Thus, compared with the traditional mode, the reagent card 50 can be accurately and efficiently pushed to the incubation area, and the automation degree is high; in addition, the incubation area is not required to be invaded, and the sealing of the incubation area is not influenced, so that the temperature stability of the incubation area is ensured.

It should be noted that, in this embodiment, the front end refers to an end close to the operator, and the rear end refers to an end far from the operator. For example, the front end of the reagent card 50 refers to the end that enters the first movement path 11 later, and the rear end of the reagent card 50 refers to the end that enters the first movement path 11 earlier.

Alternatively, the first moving channel 11 and the second moving channel 12 each include, but are not limited to, various structures such as a through hole, a through slot, a guide slot, and the like, which are flexibly provided on the bracket 10.

Optionally, in order to allow the pushing member 41 to extend into the second movement path 12, a notch 121 is formed in any wall portion of the second movement path 12, for example, and the notch 121 extends along the extending direction of the second movement path 12.

Alternatively, the specific form of the bracket 10 is not limited herein, and may be flexibly adjusted and set according to actual requirements, or may be formed by assembling a plurality of parts as shown in fig. 1, or may be designed into an integrated structure by, for example, welding.

Referring to fig. 4, in one embodiment, the card feeding device further includes a second sensor 22 and a camera 60. The second sensor 22 is disposed at the tail end or middle part of the first moving channel 11 for sensing the reagent card 50. The camera 60 is disposed on the stand 10 for acquiring bar code information of the reagent card 50. The second sensor 22 and the camera 60 are electrically connected to the controller. Thus, when the end face of the tail end of the reagent card 50 moves past the second sensor 22, the second sensor 22 can sense the position of the reagent card 50, and the distance that the first driving component 30 needs to push the reagent card 50 forward is calculated through software, specifically, when the first driving component 30 is provided with the first motor 31, the working circle number of the first motor 31 is calculated, so that the reagent card 50 moves to the photographing position, and the camera 60 is opened to identify the bar code information on the reagent card 50, so that the bar code information of the reagent card 50 is obtained; after the identification of the reagent card 50 is successful, the first motor 31 continues to operate until the reagent card 50 completely enters the second movement channel 12 and stops operating; when the second sensor 22 detects that the reagent card 50 is not in the first movement path 11, the second drive assembly 40 is activated, for example with a delay of 0.5S, so as to transport the reagent card 50 to the incubation area.

Referring to fig. 1, in one embodiment, the card feeding device further includes a third sensor 23 and a fourth sensor 24.

In this way, according to the induction signals of the third inductor 23 and the fourth inductor 24 to the pushing member 41, the controller correspondingly controls the pushing member 41 to move back and forth in the area between the third inductor 23 and the fourth inductor 24, so that the initial position and the final position of the pushing member 41 can be ensured to be accurate, and the position accuracy of pushing the reagent card 50 into the incubation area can be ensured.

As some alternatives, the third sensor 23 and the fourth sensor 24 may not be required, and the pushing member 41 may be precisely controlled to move back and forth between the initial position and the final position under the control of an internal program of the controller.

Optionally, the first sensor 21, the second sensor 22, the third sensor 23, the fourth sensor 24 each include, but are not limited to, a proximity switch, a magnetic sensor, a laser sensor, an ultrasonic sensor, and the like.

Referring to fig. 1 and fig. 7, fig. 7 is a schematic diagram showing a driving wheel and a driven wheel disposed on a first movement channel 11 according to an embodiment of the utility model. In one embodiment, the first drive assembly 30 includes: a first motor 31, a first driving wheel 32 and at least one first driven wheel 33. The first motor 31 is connected to the first driving wheel 32, and the first driving wheel 32 is located at one side of the first movement channel 11 and is used for being abutted against one side of the reagent card 50. The first driven wheel 33 is located at the other side of the first movement path 11 for abutting against the other side of the reagent card 50. In this way, when the first motor 31 rotates, the first driving wheel 32 is driven to rotate, and as the first driving wheel 32 clamps one side of the reagent card 50 through interference pressure, the first driven wheel 33 clamps the other side of the reagent card 50 through interference pressure, the reagent card 50 can be driven to move forward until the reagent card 50 moves to the tail end of the first movement channel 11, and the reagent card 50 and the first driven wheel 33 are separated from each other, at this time, the reagent card 50 completely enters the second movement channel 12.

Alternatively, first driven wheel 33 is a cylinder having an axial cross-section including, but not limited to, circular, oval, polygonal, etc. The specific shape can be flexibly adjusted and set according to actual requirements, and is not limited herein.

Referring to fig. 1 and 7, in one embodiment, the support 10 is provided with an elastic member 13, and the first driven wheel 33 is rotatably connected to the elastic member 13. Alternatively, the elastic member 13 is connected to the wall of the first movement channel 11. In this way, after the reagent card 50 is inserted into the interior of the first movement channel 11, the first driven wheel 33 is held in close abutment against the side of the reagent card 50 located in the first movement channel 11 by the elastic force provided by the elastic member 13.

Specifically, the elastic member 13 includes, but is not limited to, a structure of an elastic arm, a spring, an elastic block, an elastic column, or the like.

Referring to fig. 1 and 7, in one embodiment, the first driving wheel 32 and/or the first driven wheel 33 are/is provided as elastic wheels. In this way, the first driving wheel 32 and the first driven wheel 33 can be guaranteed to be respectively and precisely abutted against two opposite side surfaces of the reagent card 50, and the reagent card 50 can be enabled to stably move forwards to the tail end of the first movement channel 11 in the rotation process of the first driving wheel 32.

Specifically, the elastic wheel may be a rubber wheel, or an elastic material layer may be provided on the tread of the wheel to provide elastic capability.

Referring to fig. 1 and 7, in one embodiment, the number of first driven wheels 33 is at least two. Thus, the first driving wheel 32 and the first driven wheel 33 with the forefront can ensure the front-back movement of the reagent card 50; the other first driven wheel 33 maintains the direction of movement of the reagent card 50 within the channel so as to smoothly enter the underlying channel.

Referring to fig. 1 and 7, in one embodiment, the first driven wheels 33 are two, for example. Further, the centers of the first driving wheel 32, the centers of the two first driven wheels 33 are respectively arranged on the three vertexes of a right triangle, or respectively arranged on the three vertexes of an isosceles triangle.

Referring to fig. 1 and 7, in one embodiment, the first driven wheels 33 are, for example, two, and the two first driven wheels 33 are, for example, rotatably connected to the same elastic arm, and are pressed against one side of the reagent card 50 by the elastic force provided by the elastic arm, so as to ensure that the first driving wheel 32 and the reagent card 50 keep close contact, that is, the elastic arm may, for example, use a spring and/or a spring sheet to provide an uninterrupted pressing force to the side surface of the reagent card 50, so that the first driving wheel 32 correspondingly drives the reagent card 50 to move back and forth to a desired position when rotating.

In one embodiment, the top surface of the first motion channel 11 is provided with a first avoiding part, and a gap is reserved between the first avoiding part and the top surface of the reagent card 50; and/or, the top surface of the second motion channel 12 is provided with a second avoiding part, and a gap is reserved between the second avoiding part and the top surface of the reagent card 50. Thus, after the first avoiding portion is disposed on the top surface of the first moving channel 11, cross contamination caused by residue on the surface of the reagent card 50 after the reagent card 50 is applied with the sample can be prevented. Similarly, after the second avoidance portion is provided on the top surface of the second movement channel 12, cross contamination caused by residue on the surface of the reagent card 50 after the reagent card 50 is applied with the sample can be prevented.

In one embodiment, the second drive assembly 40 includes a movement mechanism including a second motor 42, a second drive wheel 43, a second driven wheel 44, and a transmission element 45. The second motor 42 is connected to the support 10, the second motor 42 is connected to a second driving wheel 43, the second driving wheel 43 is connected to a second driven wheel 44 via a transmission element 45, and the pushing member 41 is connected to the transmission element 45.

In one embodiment, the support 10 is further provided with a guide rail 14 and a sliding seat 15 slidably disposed on the guide rail 14, the guide rail 14 is disposed in the same direction as the extending direction of the second movement path 12, the sliding seat 15 is connected to the transmission element 45, and the pushing member 41 is connected to the sliding seat 15.

In one embodiment, the pusher 41 includes a first pusher 411 and a second pusher 412. The first pushing portion 411 is connected to the slide 15, and one end of the second pushing portion 412 is connected to the first pushing portion 411, and the other end of the second pushing portion 412 is used for abutting against the front end face of the reagent card 50.

Specifically, the second pushing portion 412 is perpendicular to the first pushing portion 411. Alternatively, the first pushing part 411 and the second pushing part 412 are combined to form a structure of an L-shaped bar.

In one embodiment, the first movement path 11 is located above the second movement path 12, and when the reagent card 50 moves the trailing end of the first movement path 11, the reagent card 50 drops inside the leading end of the second movement path 12. In this way, the tail end of the first moving channel 11 and the front end of the second moving channel 12 overlap each other, so that the total length of the whole transmission channel is relatively short, which is beneficial to reducing the size of the card feeding device.

Referring again to fig. 1, in one embodiment, a cushion 122 is provided on the bottom wall of the second motion channel 12. The buffer pad 122 includes, but is not limited to, buffer cotton, and the buffer pad 122 buffers the reagent card 50 falling into the second movement path 12 from the first movement path 11, so that the reagent card 50 is not damaged, and the stability is better.

In another embodiment, the first moving channel 11 and the second moving channel 12 are sequentially disposed at the same height position of the bracket 10, and the second driving assembly 40 further includes a lifting mechanism. The lifting mechanism is connected with the lifting member and is used for driving the lifting member to extend into the second movement channel 12 or move out of the second movement channel 12. Thus, the first moving path 11 and the second moving path 12 may be combined into one path. After the first driving assembly 30 completely pushes the reagent card 50 into the second moving channel 12, the lifting mechanism drives the pushing member 41 to lift, the pushing member 41 stretches into the second moving channel 12, and then the second driving assembly 40 drives the pushing member 41 to perform the card feeding action, and the pushing member 41 drives the reagent card 50 to enter the incubation area. After the reagent card 50 enters the incubation area, the second driving assembly 40 drives the pushing member 41 to reversely move and reset, and meanwhile, the lifting mechanism drives the pushing member 41 to lift, so that the pushing member 41 is reset and moved out of the second movement channel 12 to prepare for the card feeding operation of the next reagent card 50.

It should be noted that, the "elastic member 13" may be "a part of the bracket 10", that is, the "elastic member 13" is integrally formed with "other parts of the bracket 10"; or a separate component which is separable from the rest of the bracket 10, i.e., the elastic member 13 may be manufactured separately and then combined with the rest of the bracket 10 into a whole.

In one embodiment, a medical detection system includes the card entry device of any of the embodiments described above.

In the above medical detection system, when the card feeding operation is performed, the reagent card 50 is inserted into the first movement channel 11, the first sensor 21 can sense that the reagent card 50 is inserted into the first movement channel 11, the controller correspondingly controls the first driving component 30 to act, and the first driving component 30 drives the reagent card 50 to move to the tail end of the first movement channel 11 and enter the second movement channel 12; in addition, the controller also controls the second driving assembly 40 to act, and the pushing member 41 of the second driving assembly 40 moves along the second movement channel 12, so that the reagent card 50 inside the second movement channel 12 is pushed out to the incubation area. Thus, compared with the traditional mode, the reagent card 50 can be accurately and efficiently pushed to the incubation area, and the degree of automation is high; in addition, the incubation area is not required to be invaded, and the sealing of the incubation area is not influenced, so that the temperature stability of the incubation area is ensured.
