Such as when examining a patient, it is sometimes desirable to test the patient's blood. At this time, it is necessary to uniformly smear blood on a slide glass to prepare a blood smear, and observe the prepared blood smear under a microscope.

Referring to fig. 1, an embodiment of the present invention provides a slide pushing device 100 capable of pushing a drop of liquid flat to form a sheet on a slide 200. Specifically, the slide device 100 is applied to a fully automatic blood slide preparation apparatus, and can be used for preparing a blood smear by flattening blood in a drop shape to be in a sheet shape on a slide glass 200. It should be appreciated that in other embodiments, the slide apparatus 100 may be used in other devices to prepare other types of slide specimens, without limitation.
The following describes the embodiment of the present application in detail, taking the application of the pusher device 100 to a fully automatic blood pusher preparation apparatus as an example.

Specifically, the slide mechanism 30 is disposed below the substrate 40, and the pusher mechanism 20 and the pusher wiping mechanism 10 are disposed above the substrate 40. Meanwhile, the base plate 40 is provided with a through hole 41 penetrating in the thickness direction, and the slide mechanism 20 communicates with the slide mechanism 30 through the through hole 41 so that the slide mechanism 20 pushes the blood on the slide 200. More specifically, at least a portion of the slide mechanism 30 extends into the through-hole 41, and when the slide 200 is placed on the slide mechanism 30, the upper surface of the slide 200 is flush with the upper surface of the base plate 40. Of course, in other embodiments, the whole slide mechanism 30 and the slide 200 may not protrude from the lower surface of the substrate 40, and the pushing plate 25 of the pushing mechanism 20 needs to extend into the through hole 41 to push the blood when pushing the blood on the slide 200.
It is contemplated that in other embodiments, the pusher device 100 may omit the substrate 40, where the pusher mechanism 20 and the pusher wiping mechanism 10 are directly connected to the slide mechanism 30, respectively.
In one implementation, the slide mechanism 20 is fixed relative to the substrate 40, and the slide mechanism 30 pushes the slide 200 relative to the substrate 40, at which time the slide 200 moves relative to the slide mechanism 20 to achieve the effect of pushing blood. Of course, in other embodiments, the slide 200 may be stationary and the slide mechanism 20 may be moved relative to the base plate 40 to achieve a blood-pushing effect.

When the drive assembly 32 drives the slide holder 33 to move forward in the third direction relative to the fixed plate 31, the slide 25 of the slide pushing mechanism 20 can push the blood on the slide 200 placed on the slide holder 33 flat, and when the drive mechanism drives the slide holder 33 to move backward in the third direction, the slide holder 33 can return to the initial position so as to facilitate the preparation of the next blood smear.
Referring to fig. 3, the driving assembly 32 includes a fourth driving motor 321, a driving wheel 322, a belt 323, a driven wheel 324, and a screw rod 325, wherein the fourth driving motor 321 is connected with the fixed plate 31, the driving wheel 322 is connected with the driving end of the fourth driving motor 321, the screw rod 325 is connected with the fixed plate 31, the driven wheel 324 is connected with the extending end of the screw rod 325 extending out of the fixed plate 31, and the belt 323 is sleeved outside the driving wheel 322 and the driven wheel 324. Slide mount 33 is threadably coupled to screw 325 and is in sliding engagement with mounting plate 31. Thus, when the fourth driving motor 321 rotates in the forward direction, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates in the forward direction, the slide holder 33 drives the slide 200 to move in the forward direction in the third direction, and the push plate 25 of the push plate mechanism 20 pushes the blood on the slide 200 to be flat. When the fourth driving motor 321 rotates reversely, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates reversely, and the slide seat 33 moves reversely in the third direction to return to the initial position, so that the next blood smear can be made conveniently.
It is contemplated that in other embodiments, the drive assembly 32 may be provided in other arrangements, as long as the reciprocating movement of the drive slide mount 33 relative to the mounting plate 31 is accomplished.
Slide mechanism 30 still includes first slide rail 34 and first slider 35, and one of first slide rail 34 and first slider 35 is connected with fixed plate 31 fixed, and another is connected with slide holder 33 fixed, slide holder 33 realize with the sliding fit of fixed plate 31 through first slider 35 and first slide rail 34. In this embodiment, the first slide rail 34 is connected to the fixing plate 31, the first slide block 35 is connected to the slide holder 33, and the slide holder 33 is screwed to the screw 325 through the first slide block 35.
The slide holder 33 includes a bottom plate 331, a first limiting plate 332 and a second limiting plate 333, the bottom plate 331 is screwed with the screw rod 325, and the slide 200 is disposed on the bottom plate 331.

The distance between the first limiting plate 332 and the second limiting plate 333 determines the length of the slide 200, i.e., the arrangement of the second limiting plate 333 and the second limiting plate 333 plays a role in limiting the length of the slide 200.
In the second direction perpendicular to the third direction, that is, in the direction perpendicular to the connection line direction of the first limiting plate 332 and the second limiting plate 333, the two sides of the bottom plate 331 are concavely provided with the taking groove 3311, when the slide glass 200 is placed on the slide holder 33, a human hand can stretch into the taking groove 3311, so that the slide glass 200 is placed on the slide holder 33, and when the slide glass 200 on the slide holder 33 needs to be taken down, the human hand can stretch into the taking groove 3311, so that the slide glass 200 placed on the slide holder 33 is taken down. Thus, by providing the pick-up groove 3311, the slide 200 can be easily picked up and placed in the width direction of the slide 200.

In an embodiment, the first opening 1321 is disposed at a right-angle vertex of the tape cassette 132, the positioning block 133 is disposed at the same right-angle vertex of the tape cassette 132, and a right-angle portion 1331 is formed on the positioning block 133 (see fig. 21 and 22), and the wiping portion 1311 can bend under the force applied by the pushing piece 25 and abut against the right-angle portion 1331, so as to position the wiping portion 1311 and the pushing piece 25, thereby more conveniently wiping the pushing piece 25.
With continued reference to fig. 13 and with further reference to fig. 23, in one embodiment, the positioning block 133 is pivotally connected to the cassette 132, and the positioning block 133 can swing relative to the cassette 132. Specifically, the positioning block 133 is pivotally connected to the tape cassette 132 by a first shaft, and the rotation axis of the positioning block 133 with respect to the rotation of the tape cassette 132 is parallel to the rotation axes of the first winding member 135 and the second winding member 136. With continued reference to fig. 13, the wiper 13 further includes a limiting member (not shown) for limiting the swing position of the positioning block 133 relative to the tape cassette 132, where the limiting member includes a first sub-limiting member 1381 and a second sub-limiting member 1382, and the first sub-limiting member 1381 and the second sub-limiting member 1382 are respectively disposed on two sides of the positioning block 133 in the swing direction of the positioning block 133 relative to the tape cassette 132. When the pushing piece 25 applies a force to the wiping part 1311, the positioning block 133 can rotate relative to the tape cassette 132, so that the pushing piece 25 can push the wiping part 1311 to abut against the right-angle part 1331, positioning of the wiping part 1311 is facilitated, and self-adaption capability of the positioning block 133 is improved.
Wherein the first sub-limiter 1381 and/or the second sub-limiter 1382 has elasticity. When the first sub-limiter 1381 and/or the second sub-limiter 1382 have elasticity, the positioning block 133 can be automatically reset under the action of elastic restoring force when the pushing piece 25 releases the positioning block 133.
The first sub-limiting member 1381 has elasticity, specifically, the first sub-limiting member 1381 is a torsion spring, the torsion spring includes a second body, and a first end and a second end connected with the second body respectively, and the second body is connected with the tape cassette 132. More specifically, the second body is sleeved on a second shaft protruding on the tape cassette 132, the first end is abutted with the tape cassette 132, and the second end is abutted with the positioning block 133. In this way, when the pushing piece 25 applies a force to the wiping belt 131, the positioning block 133 swings relative to the belt box 132 under the driving of the wiping belt 131, and the positioning block 133 causes the torsion spring to elastically deform, so that the position of the positioning block 133 relative to the belt box 132 is finely adjusted, the pushing piece 25 is conveniently abutted to the wiping portion 1311 and the right angle portion 1331, the positioning of the wiping portion 1311 is conveniently performed, and the self-adapting capability of the positioning block 133 is improved.
The second sub-limiting member 1382 is a protrusion protruding from the tape cassette 132, so as to cooperate with the first sub-limiting member 1381 to limit the position of the positioning block 133 relative to the tape cassette 132. Specifically, the second sub-limiter 1382 is disposed on the second half-shell 16.
With continued reference to fig. 22, in one embodiment, the positioning block 133 is provided with an elastic element 134, and the elastic element 134 is used to abut against the wiping strip 131. Further, the elastic member 134 has a first abutting plane 1341 and a second abutting plane 1342 located on both sides of the right angle portion 1331, and the wiper strip 131 abuts against both the first abutting plane 1341 and the second abutting plane 1342. In this way, when the cleaning blade 200 is required, the elastic element 134 is elastically deformed to apply an elastic restoring force to the blade 25, so that the wiping strip 131 is more tightly clamped between the positioning block 133 and the blade 25, increasing the friction force between the blade 25 and the wiping portion 1311, and improving the wiping effect.
Specifically, the elastic element 134 is made of a rubber material, and the elastic element 134 is integrally formed with the positioning block 133. It should be appreciated that in other embodiments, the elastic element 134 is not limited to rubber, and the elastic element 134 may be provided separately from the positioning block 133.
Referring to fig. 13, 16 and 23, in one embodiment, the wiper 13 further includes a first tape guide 1391 and a second tape guide 1392, where the first tape guide 1391 and the second tape guide 1392 are located upstream and downstream of the positioning block 133, respectively, in the direction of movement of the wiper 131 relative to the tape cassette 132. So configured, the first tape guide 1391 and the second tape guide 1392 are capable of restricting the angle of the wiper belt 131 and facilitate tensioning of the wiper belt 131 as the wiper belt 131 moves into and out of the first opening 1321. Specifically, the first tape guide 1391 and the second tape guide 1392 are each disposed adjacent to the first opening 1321.
In an embodiment, the tape cassette 132 is further provided with a second opening 1322 in communication with the accommodating cavity, the wiper 13 further includes a third tape guide 1393, the third tape guide 1393 is disposed on the tape cassette 132, and the wiper 131 passes through the second opening 1322 and abuts against the third tape guide 1393 when the first winding member 135 is wound on the second winding member 136. In this way, the third tape guide 1393 can function in concert with the first tape guide 1391 and the second tape guide 1392 to support the wiper strip 131. The pusher wiping mechanism 10 further includes a counter wheel 1120 (see fig. 14) disposed on the first connecting plate 123, and the wiping belt 131 is sandwiched between the third belt piece 1393 and the counter wheel 1120. As the wiper belt 131 rotates relative to the cassette 132, the counter wheel 1120 rotates under the frictional force applied thereto by the wiper belt 131, so as to be dependent on the number of turns it rotates or the length of movement of the wiper belt 131.
With continued reference to fig. 14, the push-plate wiping mechanism 10 further includes a counting plate 1130 and a third inductive switch 1140, where the third inductive switch 1140 is disposed on the first connecting plate 123, the counting plate 1130 is in transmission connection with the counting wheel 1120, and the third inductive switch 1140 is capable of sensing the number of turns of the counting plate 1130 to transmit a signal to the controller, and the controller controls the rotation angle of the third driving member 120 to control the movement length of the wiping strip 131.
With continued reference to fig. 13, in one embodiment, the third tape guide 1393 and the positioning block 133 are disposed at two perpendicular vertices of the tape cassette 132, respectively, along the length of the tape cassette 132. Of course, in other embodiments, the setting positions of the counting belt guide 80 and the positioning block 133 are not limited.
Specifically, the tape cassette 132 is provided with an observation window 1323, and the amount of the wiping tape 131 wound on the first winding member 135 and the second winding member 136 can be observed through the observation window 1323. It should be appreciated that in other embodiments, the entire cartridge 132 may be made of a transparent material in order to facilitate viewing the amount of wiping strip 131 wound on the first winding member 135 and the second winding member 136.
The working principle of the pushing piece device 100 provided by the embodiment of the invention is as follows:
When it is desired to push blood on the slide 200:
The slide 25 of the slide mechanism 20 is rotated relative to the mount 21 to a slide position where the angle of inclination between the slide 25 and the slide 200 is in the range of 0 ° -90 °. When the slide glass 200 contacts with the slide glass 25, an interaction force is generated between the slide glass 200 and the slide glass 25, the slide glass 25 transmits the interaction force to the mounting block 24, the mounting block 24 compresses the first elastic piece 26, the second mounting plate 212 transmits the interaction force to the second elastic piece 29, the second mounting plate 212 slides relative to the first mounting plate 211, and the first elastic piece 26 and the second elastic piece 29 are elastically deformed so as to ensure that the slide glass 25 is tightly attached to the slide glass 200 everywhere.
When the fourth driving motor 321 of the slide mechanism 30 rotates forward, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates forward, the slide seat 33 drives the slide 200 to move forward in the third direction, and the slide 25 of the slide pushing mechanism 20 pushes the blood on the slide 200 to be flat. The slide mechanism 30 then returns to the origin.
When the push plate 25 needs to be wiped:
The cleaning medium is injected onto the wiping part 1311 by the injection member 110, and the wet wiping part 1311 is brought to the wiping position by the rotation of the third driving motor 130. The pushing plate 25 of the pushing plate mechanism 20 rotates to the cleaning position relative to the mounting seat 21, the second driving member 14 drives the wiping unit 12 to reciprocate in the second direction, and the positioning block 133 presses the wiping part 1311 against the pushing plate 25, so as to wipe the pushing plate 25.
Another embodiment of the present invention further provides a pushing mechanism 20 included in the pushing device 100.
