As described in the background art, in recent years, molecular diagnostics have been widely used in the field of in vitro diagnostics, such as performing a large batch of nucleic acid detection diagnostics, and after the detection is completed, a sample to be detected stored in a reagent strip is generally transported to a PCR module by manual or mechanical transportation, and inserted into the PCR module after aligning with corresponding hole sites of the PCR module, and then the PCR module detects the sample in the reagent strip to complete the molecular diagnostics.

However, no matter the reagent strip is transported manually or mechanically, when the reagent strip reaches a position close to the PCR module, the reagent strip cannot be accurately and quickly aligned with the corresponding hole of the PCR module, which results in poor alignment accuracy of the reagent strip and affects the overall detection speed.

Referring to fig. 1 to 2, an embodiment of the present invention provides a diagnostic apparatus 1000, wherein the diagnostic apparatus 1000 includes an automatic pushing device 100 and a detection module 200 (i.e., a PCR module) for pushing a reagent strip assembly 300 to a set position to connect with a reaction well 210 of the detection module 200 and perform detection.

Specifically, the reagent strip assembly 300 may include a reagent strip module 310, wherein a plurality of receiving grooves are formed in the reagent strip module 310 for receiving a sample and/or a reagent to be detected, and a reaction chamber 311 is disposed at one end of the reagent strip module 310, after the reagent strip module 310 reaches a side close to the detection module 200, the reaction chamber 311 can be accurately inserted into the reaction hole 210, and the PCR module directly detects the sample to be detected disposed in the reaction chamber 311.

In other embodiments, the reagent strip assembly 300 may also include a reagent strip module 310 and a reagent strip mounting seat 320, wherein a plurality of receiving grooves are formed in the reagent strip module 310 for receiving a sample and/or a reagent to be detected, a reaction chamber 311 is disposed at one end of the reagent strip module 310, the reagent strip mounting seat 320 has a mounting space for receiving the reagent strip module 310, and the reaction chamber 311 protrudes outside the mounting space to be accurately inserted into the reaction hole 210 after the reagent strip assembly 300 reaches a side close to the detection module 200.

Referring to fig. 2 to 4, specifically, the automatic pushing device 100 includes a base 10, a sliding seat 20, an adjusting assembly 30 and a driving member 50, wherein the base 10 is provided with a guide 11, the driving member 50 is disposed on the base 10 and is in transmission connection with the sliding seat 20, the sliding seat 20 is slidably disposed on the guide 11, the driving member 50 is configured to drive the sliding seat 20 to slide on the guide 11 in a reciprocating manner along an extending direction thereof, the adjusting assembly 30 is disposed on the sliding seat 20, the reagent strip assembly 40 is disposed on the adjusting assembly 30, and when the driving member 50 drives the sliding seat 20 to slide on the guide 11, the reagent strip assembly 300 and the adjusting assembly 30 slide along with the sliding seat 20 synchronously.

Moreover, the reagent strip assembly 300 can reciprocate along with the adjusting assembly 30 relative to the base 10 along the first direction, and/or the reagent strip assembly 300 can lift along the second direction L2 relative to the base 10 on the adjusting assembly 30, the first direction L1 and the second direction L2 are arranged in a crossed manner, and the extending direction of the guide 11 is crossed with the plane of the base 10 along the second direction L2.

Thus, under the action of the adjusting assembly 30, the reagent strip assembly 300 can move in the first direction L1 and/or in the second direction L2, the opposite ends of the extending direction of the guide 11 are defined as front and back positions, the end of the guide 11 away from the detection module 200 is a front end, which is defined as an initial position of the reagent strip assembly 300, the end of the guide 11 close to the detection module 200 is a back end, which is defined as a tail position of the reagent strip assembly 300, and at this time, the reagent strip assembly 300 can also move left and right relative to the base 10 in the first direction L1, and/or can move up and down relative to the base 10 in the second direction L2. The reagent strip assembly 300 and the adjusting assembly 30 can move along the extending direction of the guide piece 11 and can move up and down left and right, so that the position of the reagent strip assembly 300 in a three-dimensional space can be accurately adjusted.

Thus, the automatic pushing device 100 provided by the present application can arbitrarily adjust the position of the reagent strip assembly 300 according to the requirement, and improve the alignment precision and the transmission speed of the reagent strip assembly 300, so as to rapidly perform molecular diagnosis of the sample in the reagent strip assembly 300.

The base 10 is generally a flat plate structure disposed on a floor, a table or a predetermined position, and may be rectangular, circular or any other shape, and the guide 11 disposed thereon may be protruded from the surface of the base 10 or may be formed by cutting a groove in the base 10. For example, the base 10 may be configured as a rectangular flat plate-like structure, and a guide 11 extending along a third direction L3 is formed along the longitudinal extension direction of the base to guide the sliding seat 20 and the reagent strip assembly 300 to move along the third direction L3, wherein the third direction L3 intersects with the first direction L1 and the second direction L2.

The guide 11 may be a guide rail protruding from the surface of the base 10, or a guide groove recessed from the surface of the base 10, the guide 11 extends along the third direction L3 and guides the sliding seat 20 and the reagent strip assembly 300 to move along the third direction L3, and the specific arrangement form of the guide 11 is not limited, and it can be adaptively adjusted according to the arrangement form of the sliding seat 20.

Referring to fig. 2, when the guiding element 11 is a guiding rail protruding out of the surface of the base 10, the sliding seat 20 includes an adjusting groove 21 and a roller 22, and the adjusting assembly 30 is disposed in the adjusting groove 21 and can move in the adjusting groove 21 and drive the reagent strip assembly 300 to reciprocate along the first direction L1 relative to the base 10, so as to adjust the left and right positions of the reagent strip assembly 300 relative to the base 10. The sliding seat 20 is mounted on the guide 11 and is slidably connected to the guide 11 via a roller 22. When the driving member 50 is controlled to be opened, the roller 22 of the sliding seat 20 starts to rotate, and at this time, the sliding seat 20 slides along the extending direction of the guide member 11, before the sliding seat 20 starts to slide, during the sliding process, and after the sliding seat 20 slides to the rear end of the guide member 11, the adjusting assembly 30 can be operated, so that the adjusting assembly 30 performs left-right and up-down position adjustment on the sliding seat 20 in the first direction L1 and the second direction L2 relative to the base 10, so as to adjust the position of the reagent strip assembly 300 according to actual requirements.

In other embodiments, the sliding seat 20 may also include other structures to achieve the sliding connection with the guiding element 11, and the specific embodiment is not limited herein.

In one embodiment, the surface of the sliding seat 20 facing the reagent strip assembly 300 can be configured as a flat plate, and when the reagent strip assembly 300 is too large, only a part of the structure facing the sliding seat 20 needs to be configured to be connected with the adjusting assembly 30, and another part of the structure contacts with the surface of the sliding seat 20, so that the surface of the sliding seat 20 facing the reagent strip assembly 300 can be configured as a flat plate, and thus the reagent strip assembly 300 can be transported smoothly.

It is understood that, as long as the adjustment assembly 30 can reciprocate in the first direction L1 in the adjustment groove 21, the movement of the reagent strip assembly 300 in the first direction L1 relative to the base 10 can be realized, and the size and shape of the adjustment assembly 30 are not limited. In order to ensure the appearance and the supporting strength, it is preferable that the dimension of the adjusting assembly 30 in the first direction L1 is smaller than the dimension of the adjusting groove 21 in the first direction L1, so as to ensure that the adjusting assembly 30 is in contact with the bottom wall of the adjusting groove 21 during the movement, thereby obtaining effective support of the sliding seat 20.

In one embodiment, the adjustment assembly 30 has at least one adjustment surface, at least one of which is disposed obliquely with respect to the base 10; wherein all adjustment surfaces form mounting locations for the reagent strip assembly 300 and the adjustment surfaces are each configured to be movable in a first direction L1 relative to the base 10. The adjustment surfaces form a structure that is angularly disposed relative to the base 10, in which case the reagent strip assembly 300 is commonly supported on the adjustment assembly 30 by all of the adjustment surfaces, which may include one or more adjustment surfaces for positional adjustment of the reagent strip assembly 300.

For example, when the adjustment surfaces are arranged as one, at least a portion of the reagent strip assembly 300 is arranged on the adjustment surface, and the adjustment surface is controlled to move in the first direction L1 relative to the base 10, at least a portion of the reagent strip assembly 300 arranged on the adjustment surface is raised or lowered, and control of the local height of the reagent strip assembly 300 can be achieved.

For example, when the adjustment surface is plural, the adjustment surface may surround the circumference of the reagent strip assembly 300 to uniformly support the reagent strip assembly 300. At this time, the reagent strip assembly 300 has a plurality of supporting positions, when the plurality of adjustment surfaces are close to each other, the reagent strip assembly 300 can be extruded under the tilting action of the plurality of adjustment surfaces, the reagent strip assembly 300 is lifted relative to the base 10 in the second direction L2, or the reagent strip assembly 300 can be lowered to a position closer to the base 10 under the tilting action of the plurality of adjustment surfaces, and fall into a space surrounded by the plurality of adjustment surfaces, and at this time, the reagent strip assembly 300 is lowered relative to the base 10 in the second direction L2.

Specifically, referring to fig. 2, 4 to 6, when there are two adjusting surfaces, the adjusting surfaces include a first inclined surface 31 and a second inclined surface 32 disposed facing each other along a first direction L1, the first inclined surface 31 and the second inclined surface 32 form a mounting position of the reagent strip assembly 300, and the first inclined surface 31 and the second inclined surface 32 can move in a direction approaching or departing from each other along the first direction L1, or move toward the same side in the first direction L1 at the same time.

Correspondingly, the reagent strip assembly 300 has a third inclined surface 330 corresponding to the first inclined surface 31 and a fourth inclined surface 340 corresponding to the second inclined surface 32, when the reagent strip assembly 300 is placed on the installation position, the third inclined surface 330 is attached to the first inclined surface 31, and the fourth inclined surface 340 is attached to the third inclined surface 330. When the first inclined surface 31 and the second inclined surface 32 approach each other, the accommodating space therebetween is reduced, at this time, the third inclined surface 330 moves towards the side away from the base 10 relative to the first inclined surface 31, and at the same time, the fourth inclined surface 340 moves towards the side away from the base 10 relative to the second inclined surface 32, and at this time, the reagent strip assembly 300 is lifted in position relative to the base 10 in the second direction L2.

Similarly, when the first inclined surface 31 and the second inclined surface 32 are away from each other, the accommodating space therebetween is increased, and the third inclined surface 330 moves toward the side close to the base 10 relative to the first inclined surface 31, and the fourth inclined surface 340 moves toward the side close to the base 10 relative to the second inclined surface 32, and the reagent strip assembly 300 is lowered in position relative to the base 10 in the second direction L2.

It can be understood that when the first inclined surface 31 and the second inclined surface 32 move towards the same side in the first direction L1 at the same time, and the adjustment assembly 30 moves in the first direction L1 as a whole, the reagent strip assembly 300 can move synchronously with the adjustment assembly 30 to realize the reciprocating movement in the first direction L1 relative to the base 10.

The first inclined surface 31 and the second inclined surface 32 may be formed by providing an inclined plate-like structure on the adjusting assembly 30 to form an inclined surface, and the plate-like structure may be controlled to be capable of moving in the first direction L1 relative to the base 10, or may be formed by the structure of the adjusting assembly 30 itself. For example, in one embodiment, the adjusting assembly 30 includes a first adjusting member 33 and a second adjusting member 34 oppositely disposed along the first direction L1, wherein a side of the first adjusting member 33 facing away from the sliding seat 20 has a first inclined surface 31, and a side of the second adjusting member 34 facing away from the sliding seat 20 has a second inclined surface 32.

When the first adjusting piece 33 and the second adjusting piece 34 move in the first direction L1 in the direction of approaching to or separating from each other, the reagent strip assembly 300 can be driven to ascend and descend in the second direction L2, and when the first adjusting piece 33 and the second adjusting piece 34 move in the first direction L1 toward the same side at the same time, the reagent strip assembly 300 can be driven to move left and right in the first direction L1, so that the positions of the first adjusting piece 33 and the second adjusting piece 34 are adjusted, and the up-down left-right position of the reagent strip assembly 300 is adjusted.

Specifically, the first adjusting piece 33 and the second adjusting block 34 may each have a triangular prism shape, one side surface of which is attached to the bottom wall of the adjusting groove 21, and one side surface of which forms the first inclined surface 31 and the second inclined surface 32, respectively.

In one embodiment, referring to fig. 4, the adjusting assembly 30 further includes a fastening member 36, and the fastening member 36 is disposed through the first adjusting member 33 and the second adjusting member 34 and configured to adjust a distance between the first adjusting member 33 and the second adjusting member 34 in the first direction L1. By the arrangement of the fastening member 36, the distance between the first adjusting member 33 and the second adjusting block 34 in the first direction L1 can be automatically adjusted.

Specifically, the fastener is a screw, a through hole is formed in the first adjusting member 33, a threaded hole is formed in the second adjusting member 34, the screw penetrates through the through hole and is screwed into the threaded hole, the first adjusting member 33 and the second adjusting member 34 are fixed, when the screw is tightened, the first adjusting member 33 moves towards the direction close to the second adjusting member 34, the first adjusting member 33 and the second adjusting member are close to each other until the first adjusting member and the second adjusting member abut against each other in the first direction L1, and when the screw is loosened, the first adjusting member 33 can be controlled to be far away from the second adjusting member 34, so that the distance between the first adjusting member and the second adjusting member in the first direction L1 is increased.

In other embodiments, the fastener 36 may be multiple, and the application is not limited thereto.

Further, after the fastening element 36 is loosened, the insertion length of the fastening element 36 in the threaded hole of the second adjusting element 34 is changed, and the first adjusting element 33 moves in the first direction, and at this time, the first adjusting element 33 and the fastening element 36 can be abutted by external force, for example, when the fastening element is a screw, the fastening element is abutted by a nut of the screw, and in order to make the adjustment more automatic, referring to fig. 4, the adjusting assembly 30 further includes an elastic element 37, and the elastic element 37 is sleeved on the fastening element 36 and located between the first adjusting element 33 and the second adjusting element 34. When the fastening member 36 is tightened, the first adjusting member 33 and the second adjusting member 34 approach each other, the elastic member 37 is elastically deformed and accumulates a certain elastic force, when the fastening member 36 is loosened, the elastic force is released, the fastening member 36 and the second adjusting member 34 are fixedly connected, and the first adjusting member 33 is automatically driven away from the second adjusting member 34 by the elastic force, so that the distance between the first adjusting member 33 and the second adjusting member 34 is adjusted. Specifically, the elastic member 37 may be an elastic structure such as a spring, a torsion spring, etc., and the specific arrangement form thereof is not limited herein.

It will be appreciated that the reagent strip assembly 300 is also provided with corresponding aperture formations for connection to the mounting member 40.

Specifically, to accommodate the fixation of the reagent strip assembly 300 in different positions, referring to fig. 4, the fixation hole 35 is a kidney-shaped hole in which the fixing member 40 can slide in the first direction L1 and the second direction L1, and the fixing member 40 slides in the kidney-shaped hole when the first adjusting member 33 and the second adjusting member 34 approach or move away from each other.

In one embodiment, the driving member 50 may be a screw motor, which has a simple structure and high control precision, and can precisely drive the reagent strip assembly 300 to a certain position, while avoiding the conventional conveyor belt pushing mode, so that the reagent strip assembly 300 has higher pushing precision.
