TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a push piece tape cartridge. BACKGROUND

[0002] Microscopic examination of blood push piece is a basic method of blood cytology examination, and is of great value to diagnosis of various blood diseases, and is widely used in clinical examination.

[0003] Preparation of blood push piece requires push piece operation on a slide, which is to push the drop-shaped specimen on the slide into a uniform distribution by using a push piece. In the prior art, a disposable push piece is installed on the push piece head of a blood push piece preparation device, and the push piece is moved by the push piece head to complete a push piece operation. In order to avoid mutual contamination between samples, the used push piece on the push piece head needs to be removed before the next push piece operation, and a new push piece needs to be installed on the push piece head. Therefore, a push piece storage mechanism, a push piece exit mechanism and a piece changing mechanism need to be provided on the blood push piece preparation device, resulting in complex structure and high manufacturing cost. SUMMARY

[0004] Therefore, it is necessary to provide a push piece tape cartridge which can improve the above-mentioned defects in view of the problem of complex structure and high manufacturing cost of the blood push piece preparation device in the prior art.

[0005] A push piece tape cartridge comprises:

[0006] A shell is replaceably installed on a device body, and the shell has a receiving slot for a push piece head of the device body, and the receiving slot has an opening;

[0007] A pay-off shaft is rotatably connected to the shell, and is used to pay off and output a push piece tape, and to make the push piece tape pass through the receiving slot; and

[0008] A take-up shaft is rotatably connected to the shell, and is used to take up the push piece tape.

[0009] The push piece head can be moved along the receiving slot towards the opening to a push piece position, so that the push piece tape is wrapped around the part of the push piece head protruding from the opening, and the part of the push piece head wrapped with the push piece tape is used for push piece operation.

[0010] In one embodiment, the take-up shaft has a power connection hole for separable connection with a driving shaft, so that the take-up shaft is driven to rotate by the driving shaft.

[0011] The pay-off shaft has a damping connection hole for separable connection with a damping shaft, so that the damping shaft retards rotation of the pay-off shaft.

[0012] In one of the embodiments, the pusher tape cartridge further comprises a locking assembly, which is configured to be controllably switched between a locking state and a non-locking state.

[0013] When the locking assembly is in the locking state, the locking assembly is in rotational stop cooperation with the unwinding shaft and the winding shaft; when the locking assembly is in the non-locking state, the locking assembly is separated from the unwinding shaft and the winding shaft.

[0014] In one of the embodiments, the locking assembly comprises a first locking member, a second locking member and a control member, which are all rotatably connected to the housing; the first locking member is provided with a first locking portion and a first force receiving portion, the second locking member is provided with a second locking portion and a second force receiving portion, the control member is provided with a transmission portion and an operation portion, and the transmission portion is in transmission cooperation with the first force receiving portion and the second force receiving portion.

[0015] The operation portion can be switched between a locking position and a non-locking position under the action of an external force; when the operation portion is rotated to the locking position, the control member drives the first locking member to rotate to the first locking portion in stop cooperation with the unwinding shaft through the transmission portion and the first force receiving portion, and drives the second locking member to rotate to the second locking portion in stop cooperation with the winding shaft through the transmission portion and the second force receiving portion; when the operation portion is rotated to the non-locking position, the control member drives the first locking member to rotate to be separated from the unwinding shaft through the transmission portion and the first force receiving portion, and drives the second locking member to rotate to be separated from the winding shaft through the transmission portion and the second force receiving portion.

[0016] In one of the embodiments, the locking assembly further comprises a third elastic member, which is connected between the housing and the control member, for providing a pre-tightening force for driving the control member to rotate the operation member from the non-locking position to the locking position.

[0017] In one of the embodiments, the unwinding shaft is coaxially fixed with a first locking disc, which is provided with a plurality of first locking recesses arranged at intervals in the circumferential direction, and the first locking portion can be rotated to locking stop cooperation or separation with a corresponding first locking recess along with the rotation of the first locking member.

[0018] In one of the embodiments, the winding shaft is coaxially fixed with a second locking disc, which is provided with a plurality of second locking recesses arranged at intervals in the circumferential direction, and the second locking portion can be rotated to locking stop cooperation or separation with a corresponding second locking recess along with the rotation of the second locking member.

[0019] In one of the embodiments, the two ends of the accommodation groove in the first direction are a closed end and the opening respectively;

[0020] The pusher tape cartridge further comprises a guide tape assembly, which comprises a guide tape post mounted on the shell, the guide tape post being arranged on both sides of the opening of the accommodation groove in a second direction perpendicular to the first direction, and the guide tape post being for the pusher tape to pass through to guide the pusher tape to pass through the opening of the accommodation groove.

[0021] In one of the embodiments, the shell comprises a pay-off area and a take-up area respectively on both sides of the accommodation groove in the second direction, the pay-off shaft being located in the pay-off area, and the take-up shaft being located in the take-up area;

[0022] The guide tape post comprises a first guide tape post, a second guide tape post and a third guide tape post; the first guide tape post and the second guide tape post are arranged in the pay-off area to guide the pusher tape payed off by the pay-off shaft to the opening of the accommodation groove; and the third guide tape post is arranged in the take-up area to guide the pusher tape passing through the accommodation groove to the take-up shaft.

[0023] In one of the embodiments, the guide tape post further comprises a fourth guide tape post, the fourth guide tape post being arranged in the pay-off area and being located upstream of the first guide tape post and the second guide tape post, and the fourth guide tape post being used to guide the pusher tape payed off by the pay-off shaft to between the first guide tape post and the second guide tape post.

[0024] When the pusher operation is needed, the pusher head is moved from the initial position to the pusher position along the accommodation groove (i.e. along the first direction), so that the part of the pusher head protruding from the opening is covered by the pusher tape and is in contact with the slide on the slide holder. Then, the relative movement between the pusher head and the slide holder in the second direction is generated, so that the part of the pusher head covered by the pusher tape pushes the sample on the slide to be distributed uniformly (i.e. the pusher operation is completed). After the pusher operation is completed, the pusher head is moved from the pusher position to the initial position along the accommodation groove, so that the pusher head is separated from the pusher tape. Then, the rotation of the pay-off shaft and the take-up shaft makes the pusher tape move downstream by a certain distance, so that the pusher tape between the pusher head and the slide holder is not contaminated, and is ready for the next pusher operation.

[0025] In this way, the pusher head is isolated from the sample on the slide by the pusher tape, and the pusher tape can be transported downstream to make the pusher head be covered by the uncontaminated pusher tape before each pusher operation, so that continuous pusher operation can be realized. Compared with the prior art of installing a disposable pusher on the pusher head, there is no need to configure a pusher storage mechanism, a pusher exit mechanism and a pusher replacement mechanism, etc., so that the structure of the blood pusher preparation device is greatly simplified, and the manufacturing cost is reduced.

[0046] It should be noted that when an element is referred to as being "fixed to" or "set to" another element, it can be directly on the other element or there can be an intermediate element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there can be an intermediate element. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0047] Referring to Figures 1 to 3 , an embodiment of the present application provides a blood push piece preparation device, which comprises a device body (not marked in the figure) and a push piece tape box 1. The device body comprises a slide glass bearing mechanism 20 and a push piece forming mechanism 30. The slide glass bearing mechanism 20 has a slide glass seat 21 for bearing a slide glass A. The push piece forming mechanism 30 has a push piece head 31, and the push piece head 31 is located on one side of the slide glass seat 21 in a first direction X. The push piece tape box 1 is used to output a push piece tape B in a roll and make the push piece tape B pass between the push piece head 31 and the slide glass seat 21.

[0048] Among them, the push piece head 31 is configured to be controllably moved along the first direction X to an initial position (see Figure 1 and Figure 2 illustrated) away from the slide glass seat 21 or a push piece position (see Figure 4 illustrated) close to the slide glass seat 21. When the push piece head 31 moves to the push piece position, the push piece head 31 is covered by the push piece tape B, and the push piece head 31 and the slide glass seat 21 generate relative motion in a second direction Y, so that the part of the push piece head 31 covered by the push piece tape B performs a push piece operation on the slide glass A on the slide glass seat 21.

[0049] The above-mentioned blood push piece preparation device, in actual use, first, the slide glass A is placed on the slide glass seat 21, and the push piece head 31 is controlled to move from the initial position along the first direction X towards the push piece tape B and the slide glass seat 21 (as Figure 2downwardly until reaching the pushing position. At this time, the pushing head 31 is covered by the pushing tape B at one end of the slide holder 21, and the end of the pushing head 31 covered by the pushing tape B is in contact with the slide A on the slide holder 21. Then, the pushing head 31 and the slide holder 21 are controlled to generate relative movement in the second direction Y, so that the end of the pushing head 31 covered by the pushing tape B moves along the slide holder 21 to perform the pushing operation, i.e. to push the drop-shaped sample on the slide A into a uniform distribution. After the pushing operation is completed, the pushing head 31 is reset from the pushing position to the initial position along the first direction X (i.e. as shown in FIG. 1A), and the pushing tape B is wound on the pushing tape spool 22. Figure 2 downwardly, so that the pushing head 31 is separated from the pushing tape B. Before the next pushing operation, a certain length of the pushing tape B is continuously unwound and output downstream by the pushing tape cartridge 1, so that the part of the pushing tape B contaminated by the sample during the last pushing operation moves downstream, thereby making the pushing tape B between the pushing head 31 and the slide holder 21 uncontaminated, and further avoiding mutual contamination between samples during the next pushing operation.

[0050] Thus, in the blood pushing sheet preparation device described above, the pushing head 31 is isolated from the sample on the slide A by the pushing tape B, and the pushing tape B can be transported downstream, so that the pushing head 31 is covered by uncontaminated pushing tape B before each pushing operation, thereby realizing continuous pushing operation. Compared with the prior art of installing a disposable pushing sheet on the pushing head 31, there is no need to configure a pushing sheet storage mechanism, a pushing sheet exit mechanism and a sheet changing mechanism, etc., thereby greatly simplifying the structure of the blood pushing sheet preparation device and reducing the manufacturing cost.

[0051] In some embodiments, the pushing head 31 is configured to be controllably oscillated about an oscillation axis parallel to the third direction Z. The third direction Z is perpendicular to both the first direction X and the second direction Y. Thus, the oscillation of the pushing head 31 about the oscillation axis is used to adjust the angle (i.e. the pushing angle a) of the pushing head 31 relative to the slide A on the slide holder 21, which is beneficial to improve the pushing effect and further improve the quality of the blood pushing sheet.

[0052] Specifically, the pushing forming mechanism 30 further includes a mounting frame 32, a lifting seat 33, a lifting drive assembly (not labeled in the figure) and an oscillation shaft 35. The lifting seat 33 is movably connected to the mounting frame 32 along the first direction X. The lifting drive assembly is drivingly connected to the lifting seat 33 to drive the lifting seat 33 to move along the first direction X. The oscillation shaft 35 is rotatably connected to the lifting seat 33, and the rotation axis of the oscillation shaft 35 is the above-mentioned oscillation axis. The pushing head 31 is mounted on the oscillation shaft 35, so that the pushing head 31 is oscillated by the oscillation shaft 35, thereby achieving the purpose of adjusting the pushing angle a.

[0053] Further, the lifting drive assembly includes a rotary driving member 341, a cam 342 and a first elastic member 342 (seeFigure 5 The rotary drive 341 is mounted on the mounting bracket 32, and the cam 342 is mounted on the output shaft of the rotary drive 341 and is in transmission cooperation with the lifting seat 33. When the cam 342 is driven to rotate by the rotary drive 341, it provides power to the lifting seat 33 to move the pusher head 31 from its initial position to the pusher position (i.e., as shown in the image). Figure 2 The first elastic element 342 is connected to the mounting bracket 32 ​​and the lifting seat 33 respectively, and provides the lifting seat 33 with the driving force to move the pusher head 31 from the pusher position to the initial position (i.e., as the pusher head 31 moves downward). Figure 2 The preload force (for the slide pusher 31 to move upwards) is applied. Thus, when the slide pusher 31 needs to perform a slide pushing operation, the rotary drive 341 drives the cam 342 to rotate, thereby using the transmission cooperation between the cam 342 and the lifting seat 33 to move the lifting seat 33 downwards (at this time, the lifting seat 33 moves downwards against the preload force provided by the first elastic element 342) until the slide pusher 31 moves downwards with the lifting seat 33 to the slide pushing position. At this time, the slide pusher 31 is covered by the slide pushing belt B and contacts the glass slide A on the slide holder 21, so that the slide pusher 31 can perform a slide pushing operation on the glass slide A when the slide pusher 31 and the slide holder 21 move relative to each other in the second direction Y. After the slide pushing operation is completed, the rotary drive 341 drives the cam 342 to rotate, and under the action of the preload force provided by the first elastic element 342, the lifting seat 33 moves upwards until the slide pusher 31 moves upwards with the lifting seat 33 to the initial position. At this time, the slide pusher 31 separates from the slide pushing belt B, so that the slide pushing belt B can move downwards. Optionally, the rotation drive 341 can be a motor. The first elastic element 342 can be a tension spring.

[0054] Furthermore, the mounting frame 32 is provided with a first slide rail 322 extending longitudinally along the first direction X, and the lifting seat 33 is provided with a first slider 331 that slides in cooperation with the first slide rail 322. In this way, by using the first slider 331 to slide along the first slide rail 322, the movement of the lifting seat 33 relative to the mounting frame 32 along the first direction X is guided, making the movement of the lifting seat 33 more stable and reliable.

[0055] In a specific embodiment, the slide-forming mechanism 30 further includes a second elastic element 312. The slide-pushing head 31 is movably connected to the swing shaft 35 along the first direction X. The second elastic element 312 abuts against the swing shaft 35 and the slide-pushing head 31 to buffer the slide-pushing head 31. Thus, when the slide-pushing head 31 moves from its initial position to the slide-pushing position, the buffering effect of the second elastic element 312 prevents the slide-pushing head 31 from causing a large impact on the glass slide A, thus avoiding damage to the glass slide A. Optionally, the second elastic element 312 can be a compression spring.

[0056] It should be noted that the push piece forming mechanism 30 is not limited to the structure in the above embodiment to realize the movement of the push piece head 31 along the first direction X and the swing around the swing axis. In other embodiments, other structures can also be used to realize, for example: the lifting driving assembly is mounted on the swing shaft 35, so that the lifting driving assembly swings with the swing shaft 35. At the same time, the push piece head 31 is mounted on the driving end of the lifting driving assembly, so that the lifting driving assembly can drive the push piece head 31 to move along the first direction X.

[0057] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , in the embodiment of the present application, the push piece tape box 1 is replaceably mounted on the mounting frame 32. In this way, when the unwinding of the push piece tape B in the push piece tape box 1 is completed, the push piece tape box 1 can be removed and a new push piece tape box 1 can be installed to continue the push piece operation, which is convenient and fast, and reduces downtime.

[0058] In some embodiments, the push piece tape box 1 includes a shell 10 (see Figure 11 ) and an unwinding shaft 11 (see Figure 11 ) and a winding shaft 12 (see Figure 11 ) which are rotatably arranged in the shell 10. The shell 10 is replaceably mounted on the mounting frame 32, and the unwinding shaft 11 is used to output the push piece tape B between the push piece head 31 and the slide holder 21. The winding shaft 12 is used to wind the push piece tape B output by the unwinding shaft 11. In this way, when the push piece head 31 moves to the push piece position and performs the push piece operation, the unwinding shaft 11 is in a state of stopping unwinding, and the winding shaft 12 is in a state of stopping winding. When the push piece operation is completed, the push piece head 31 moves to the initial position, the unwinding shaft 11 unwinds the push piece tape B by a moving length, and the winding shaft 12 winds the push piece tape B by a corresponding length, until the push piece tape B between the push piece head 31 and the slide holder 21 is not contaminated, ready for the next push piece operation.

[0059] In the embodiment, the push piece forming mechanism 30 further includes a winding driving assembly, which includes a driving shaft 383 and a winding driving piece 384. The driving shaft 383 is rotatably connected to the mounting frame 32 around its own axis, and is connected or disconnected with the winding shaft 12. The winding driving piece 384 is drivingly connected with the driving shaft 383 to drive the driving shaft 383 to rotate. In this way, when the push piece tape box 1 is mounted to the mounting frame 32 in place, the driving shaft 383 is connected with the winding shaft 12, so that the winding driving piece 384 drives the winding shaft 12 to rotate through the driving shaft 383, thereby pulling the push piece tape B to wind on the winding shaft 12, and at the same time driving the unwinding shaft 11 to rotate to unwind the push piece tape B; when the push piece tape box 1 is removed from the mounting frame 32, the driving shaft 383 is disconnected with the winding shaft 12.

[0060] Referring to Figure 6 and Figure 7 As shown in the figure, in the embodiment, the driving shaft 383 comprises a first shaft body 3831, a first adapter 3832 and a first torsion spring 3833. The first shaft body 3831 is rotatably connected to the mounting frame 32, and one end thereof is connected to the winding driving member 384, and the other end thereof is sleeved with the first adapter 3832, which is rotatable relative to the first shaft body 3831. The first shaft body 3831 has a first tooth groove d, and the first adapter 3832 has a first matching tooth e inserted into the first tooth groove d. In the circumferential direction of the first shaft body 3831, the size of the first tooth groove d is greater than the size of the first matching tooth e, so that the first matching tooth e can move in the first tooth groove d when the first adapter 3832 rotates relative to the first shaft body 3831, that is, the first tooth groove d is used to limit the first matching tooth e in the circumferential direction of the first shaft body 3831, so as to limit the angle range of the rotation of the first adapter 3832 relative to the first shaft body 3831.

[0061] The first torsion spring 3833 is sleeved on the first shaft body 3831, and one force arm of the first torsion spring 3833 abuts against the side wall of the first tooth groove d, and the other force arm of the first torsion spring 3833 abuts against the first matching tooth e, so as to ensure that the first matching tooth e is closely attached to one side wall of the first tooth groove d when no external force is applied, thereby avoiding the rotation of the first adapter 3832 relative to the first shaft body 3831.

[0062] In this way, during the movement of the push piece head 31 from the initial position to the push piece position, the push piece head 31 drives the push piece belt B to move towards the slide seat 21, so that the push piece belt B covers the end of the push piece head 31 towards the slide seat 21. At the same time, under the action of the force applied by the push piece head 31 to the push piece belt B, the push piece belt B drives the winding shaft 12 and the first adapter 3832 connected thereto to rotate a certain angle against the elastic force of the first torsion spring 3833, thereby releasing a section of the push piece belt B, and further avoiding the tearing or breaking of the push piece belt B.

[0063] It should be noted that when the pusher belt B is outputted, the winding shaft 12 rotates to pull the pusher belt B to be wound on the winding shaft 12, and the pusher belt B drives the unwinding shaft 11 to rotate, so that the unwinding shaft 11 unwinds and outputs the pusher belt B. However, when the winding shaft 12 stops rotating, the unwinding shaft 11 continues to rotate due to inertia and continues to unwind the pusher belt B, so that the pusher belt B between the unwinding shaft 11 and the winding shaft 12 is too long and is in a slack state, which causes the pusher belt B to be unable to be wrapped on the pusher head 31 or to be wrapped too loosely. In order to solve this problem, in the embodiment, the pusher forming mechanism 30 further comprises a damping assembly (not marked in the figure), which comprises a damping shaft 381 and a damper 382. The damping shaft 381 is rotatably connected to the mounting frame 32 about its own axis, and is connected or separated from the unwinding shaft 11. The damper 382 is in transmission connection with the damping shaft 381, so as to block the rotation of the damping shaft 381 by using the damper 382, thereby achieving the purpose of blocking the rotation of the unwinding shaft 11.

[0064] In this way, when the winding shaft 12 stops rotating, the unwinding shaft 11 and the damping shaft 381 connected thereto can immediately stop rotating under the blocking action of the damper 382, so that the pusher belt B between the unwinding shaft 11 and the winding shaft 12 is in a tension state, thereby enabling the pusher belt B to be wrapped on the pusher head 31 tightly when the pusher head 31 moves to the pusher position.

[0065] Please refer to Figure 6 and Figure 8 Further, the damping shaft 381 comprises a second shaft body 3811, a second connecting head 3812 and a second torsional spring 3813. The second shaft body 3811 is rotatably connected to the mounting frame 32, and one end thereof is connected to the damper 382, and the other end thereof is sleeved with the second connecting head 3812. Moreover, the second connecting head 3812 is rotatable relative to the second shaft body 3811.

[0066] The second shaft body 3811 has a second tooth groove g, and the second connecting head 3812 has a second matching tooth h inserted into the second tooth groove g. In the circumferential direction of the second shaft body 3811, the size of the second tooth groove g is greater than the size of the second matching tooth h, so that the second matching tooth h can move in the second tooth groove g when the second connecting head 3812 rotates relative to the second shaft body 3811, that is, the second tooth groove g is used to limit the second matching tooth h in the circumferential direction of the second shaft body 3811, so as to limit the angle range of the rotation of the second connecting head 3812 relative to the second shaft body 3811.

[0067] The second torsion spring 3813 is sleeved on the second shaft body 3811, and one force arm of the second torsion spring 3813 abuts against a side wall of the second tooth groove g, and the other force arm of the second torsion spring 3813 abuts against the second matching tooth h, so as to ensure that the second matching tooth h is tightly combined with the side wall of the second tooth groove g when no external force is applied, and the second adapter 3812 is prevented from rotating relative to the second shaft body 3811.

[0068] Therefore, during the movement of the push piece head 31 from the initial position to the push piece position, the push piece head 31 drives the push piece belt B to move towards the slide seat 21, so that the push piece belt B covers the end of the push piece head 31 towards the slide seat 21. At the same time, under the action of the force applied by the push piece head 31 to the push piece belt B, the push piece belt B drives the unwinding shaft 11 and the second adapter 3812 matched thereto to rotate a certain angle against the elastic force of the second torsion spring 3813, so as to release a section of the push piece belt B, thereby avoiding that the push piece belt B is torn or broken.

[0069] Please continue to refer to Figure 5 As shown in the figure, in the embodiment of the application, the push piece forming mechanism 30 further comprises a moving seat 36 movably connected to the mounting frame 32 along the axial direction of the driving shaft 383 and the damping shaft 381. The moving seat 36 is used to replaceably install the push piece belt box 1, and the moving seat 36 has a disengaged position and an engaged position during the movement relative to the mounting frame 32.

[0070] When the moving seat 36 moves to the disengaged position, the driving shaft 383 is disengaged from the winding shaft 12, the damping shaft 381 is disengaged from the unwinding shaft 11, and the push piece belt B between the winding shaft 12 and the unwinding shaft 11 exits between the push piece head 31 and the slide seat 21, so as to facilitate the dismounting of the push piece belt box 1 from the moving seat 36 and the installation of a new push piece belt box 1 on the moving seat 36. When the moving seat 36 moves to the engaged position, the driving shaft 383 is engaged with the winding shaft 12, the damping shaft 381 is engaged with the unwinding shaft 11, and the push piece belt B between the winding shaft 12 and the unwinding shaft 11 passes through between the push piece head 31 and the slide seat 21, so that when the push piece head 31 moves from the initial position to the push piece position, the push piece belt B covers the push piece head 31.

[0071] When the push strip tape B in the push strip tape cartridge 1 is unwound, the push strip tape cartridge 1 needs to be replaced. First, the moving seat 36 is moved from the matching position to the separating position, so that the driving shaft 383 and the damping shaft 381 are separated from the winding shaft 12 and the unwinding shaft 11 of the push strip tape cartridge 1 respectively, and the push strip tape B between the winding shaft 12 and the unwinding shaft 11 is out of the push head 31 and the slide seat 21. Then, the push strip tape cartridge 1 on the moving seat 36 is removed, and a new push strip tape cartridge 1 is placed on the moving seat 36. Finally, the moving seat 36 is moved to the matching position again, so that the driving shaft 383 and the damping shaft 381 are matched with the winding shaft 12 and the unwinding shaft 11 of the push strip tape cartridge 1 respectively, so that the driving shaft 383 can drive the winding shaft 12 to rotate, and the damping shaft 381 can retard the rotation of the unwinding shaft 11 under the action of the damper 382.

[0072] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the slide seat 21 is movably connected to the mounting frame 32 in the second direction Y. The slide carrying mechanism 20 further comprises a translation assembly installed on the mounting frame 32 and drivingly connected to the slide seat 21 to drive the slide seat 21 to move relative to the push head 31 in the second direction Y, so that the push head 31 in the push position (at this time, the push strip tape B is wrapped on the push head 31) performs the push operation on the drop-shaped sample on the slide A carried on the slide seat 21.

[0073] In an embodiment, the translation assembly comprises a lead screw 22, a lead screw driving member 23 and a lead screw nut 24. The lead screw 22 is rotatably connected to the mounting frame 32 about its own axis, and the axial direction of the lead screw 22 is parallel to the second direction Y. The lead screw driving member 23 is installed on the mounting frame 32 and drivingly connected to the lead screw 22 to drive the lead screw 22 to rotate about its own axis. The lead screw nut 24 is threadedly connected to the lead screw 22, so that the lead screw 22 drives the lead screw nut 24 to move along the axial direction of the lead screw 22 (i.e. the second direction Y) when the lead screw 22 rotates. The lead screw nut 24 is fixedly connected to the slide seat 21, so that the slide seat 21 can move along the second direction Y together with the lead screw nut 24. Optionally, the lead screw driving member 23 can be a pneumatic cylinder.

[0074] It should be noted that the translation assembly is not limited to the structure of the lead screw pair to drive the slide seat 21 to move in the second direction Y. In other embodiments, the translation assembly can also use linear driving structures such as electric cylinders, pneumatic cylinders, gear racks, etc., which are not limited here.

[0075] Please refer to Figures 9 to 11As shown, in another aspect, the application also provides a pusher tape cartridge 1. In embodiments of the application, the pusher tape cartridge 1 comprises a housing 10, a pay-off shaft 11 and a take-up shaft 12. The housing 10 is replaceably mounted on the device body, and has a receiving slot 101 through which a pusher head 31 passes, the receiving slot 101 having an opening 102. The pay-off shaft 11 is rotatably connected to the housing 10, and is used to pay off the pusher tape B and pass the pusher tape B through the receiving slot 101. The take-up shaft 12 is rotatably connected to the housing 10, and is used to take up the pusher tape B.

[0076] The pusher head 31 can move along the receiving slot 101 towards the opening 102 to a pusher position, so that the pusher tape B covers the portion of the pusher head 31 that protrudes from the opening 102, and the portion of the pusher head 31 covered by the pusher tape B is used to perform the pusher operation.

[0077] The pusher tape cartridge 1 described above, when a pusher operation is required, the pusher head 31 moves along the receiving slot 101 (i.e. in the first direction X) from the initial position to the pusher position, so that the portion of the pusher head 31 that protrudes from the opening 102 is covered by the pusher tape B, and is in contact with the slide A on the slide holder 21. Then, the pusher head 31 and the slide holder 21 move relative to each other in the second direction Y, so that the portion of the pusher head 31 covered by the pusher tape B pushes the drop-shaped sample on the slide A into a uniform distribution (i.e. completes the pusher operation). After the pusher operation is completed, the pusher head 31 moves along the receiving slot 101 from the pusher position to the initial position, so that the pusher head 31 is separated from the pusher tape B. Then, the pay-off shaft 11 and the take-up shaft 12 rotate to move the pusher tape B downstream by a certain distance, so that the pusher tape B between the pusher head 31 and the slide holder 21 is uncontaminated, and is ready for the next pusher operation.

[0078] In this way, the pusher head 31 is isolated from the sample on the slide A by the pusher tape B, and the pusher tape B can be transported downstream to ensure that the pusher head 31 is covered by uncontaminated pusher tape B before each pusher operation, so that continuous pusher operations can be achieved. Compared with the prior art in which a disposable pusher is mounted on the pusher head 31, there is no need to configure a pusher storage mechanism, a pusher ejection mechanism and a pusher replacement mechanism, etc., so that the structure of the blood pusher preparation device is greatly simplified, and the manufacturing cost is reduced.

[0079] In specific embodiments, the take-up shaft 12 has a power connection hole 121 for detachable connection with the first adapter 3832 of the driving shaft 383, so that the driving shaft 383 drives the take-up shaft 12 to rotate. The pay-off shaft 11 has a damping connection hole 111 for detachable connection with the damping shaft 381, so that the damping shaft 381 retards the rotation of the pay-off shaft 11.

[0080] Further, one of the inner wall of the power connecting hole 121 and the outer wall of the first adapter 3832 has first transmission teeth f (see Figure 7 ), and the other of the inner wall of the power connecting hole 121 and the outer wall of the first adapter 3832 has first transmission tooth grooves 1211. When the first adapter 3832 is adapted into the power connecting hole 121, the first transmission teeth f are engaged with the first transmission tooth grooves 1211, so that the rotation of the first adapter 3832 is transmitted to the winding shaft 12.

[0081] Further, one of the inner wall of the damping connecting hole 111 and the outer wall of the second adapter 3812 has second transmission teeth i (see Figure 8 ), and the other of the inner wall of the damping connecting hole 111 and the outer wall of the second adapter 3812 has second transmission tooth grooves 1111. When the second adapter 3812 is adapted into the damping connecting hole 111, the second transmission teeth i are engaged with the second transmission tooth grooves 1111, so that the damping force of the damper 382 is transmitted to the unwinding shaft 11, and the unwinding shaft 11 is damped.

[0082] Please refer to Figures 11 to 13 In some embodiments, the pusher tape cartridge 1 further comprises a locking assembly 13 configured to be controllably switched between a locked state (see Figure 12 ) and an unlocked state (see Figure 13 ). When the locking assembly 13 is in the locked state, the locking assembly 13 is in rotational stop cooperation with the unwinding shaft 11 and the winding shaft 12 to prevent the unwinding shaft 11 and the winding shaft 12 from rotating; when the locking assembly 13 is in the unlocked state, the locking assembly 13 is separated from the unwinding shaft 11 and the winding shaft 12 to allow the unwinding shaft 11 and the winding shaft 12 to rotate. Specifically, before the pusher tape cartridge 1 is installed on the device body, the locking assembly 13 is in the locked state, so as to prevent the unwinding shaft 11 and the winding shaft 12 from rotating, avoiding the unwinding shaft 11 and / or the winding shaft 12 from rotating randomly to cause the pusher tape B between the unwinding shaft 11 and the winding shaft 12 to be too long and in a slack state. When the pusher tape cartridge 1 is installed on the device body, the locking assembly 13 is in the unlocked state, so that the unwinding shaft 11 and the winding shaft 12 rotate under the action of the driving shaft 383 and the damping shaft 381 respectively, and the unwinding output pusher tape B is realized.

[0083] Please refer to Figures 12 to 15As shown, in particular embodiments, the locking assembly 13 comprises a first locking member 132, a second locking member 133 and a control member 131, which are all rotatably connected to the housing 10. The first locking member 132 has a first locking portion 1322 and a first force receiving portion 1321, the second locking member 133 has a second locking portion 1332 and a second force receiving portion 1331, and the control member 131 has a transmission portion 1312 and an operation portion 1311. The transmission portion 1312 is in transmission cooperation with the first force receiving portion 1321 and the second force receiving portion 1331, so that the control member 131 can drive the first locking member 132 and the second locking member 133 to rotate through the transmission portion 1312 when the control member 131 rotates.

[0084] The operation portion 1311 of the control member 131 can rotate between a locking position and a non-locking position under the action of an external force. When the operation portion 1311 of the control member 131 rotates to the locking position, the control member 131 drives the first locking member 132 to rotate to the first locking portion 1322 through the transmission portion 1322 and the first force receiving portion 1321, so as to stop the rotation of the unwinding shaft 11. At the same time, the control member 131 drives the second locking member 133 to rotate to the second locking portion 1332 through the transmission portion 1312 and the second force receiving portion 1331, so as to stop the rotation of the winding shaft 12. It can be understood that at this time, the locking assembly 13 is in the above-mentioned locking state.

[0085] When the operation portion 1311 of the control member 131 rotates to the non-locking position, the control member 131 drives the first locking member 132 to rotate away from the unwinding shaft 11 through the transmission portion 1312 and the first force receiving portion 1321, so as to allow the unwinding shaft 11 to rotate. At the same time, the control member 131 drives the second locking member 133 to rotate away from the winding shaft 12 through the transmission portion 1312 and the second force receiving portion 1331, so as to allow the winding shaft 12 to rotate. It can be understood that at this time, the locking assembly 13 is in the above-mentioned non-locking state.

[0086] In particular embodiments, the locking assembly 13 further comprises a third elastic member (not shown in the figure), which is connected between the housing 10 and the control member 131, and is used to provide a pre-tightening force for driving the control member 131 to rotate the operation portion 1311 from the non-locking position to the locking position. In this way, when the external force acting on the operation portion 1311 of the control member 131 disappears, the control member 131 rotates from the non-locking position to the locking position under the action of the pre-tightening force provided by the third elastic member, so that the locking assembly 13 is in the locking state and the rotation of the unwinding shaft 11 and the winding shaft 12 is prevented. When the operation portion 1311 of the control member 131 bears an external force, the control member 131 rotates to the non-locking position against the pre-tightening force provided by the third elastic member under the action of the external force, allowing the unwinding shaft 11 and the winding shaft 12 to rotate. Optionally, the third elastic member can be a torsional spring.

[0087] In a specific embodiment, the locking assembly 13 further includes a fourth elastic element 135, which is connected between the housing 10 and the first locking element 132. This fourth elastic element 135 provides a preload force to cause the first locking element 132 to rotate from the position where the first locking portion 1322 is separated from the unwinding shaft 11 to the position where it is in anti-rotation engagement. Thus, when the external force on the operating portion 1311 of the control element 131 disappears, under the preload force provided by the third elastic element, the control element 131 rotates from the unlocked position to the locked position. Simultaneously, under the preload force provided by the fourth elastic element 135, the first locking element 132 rotates from the position where the first locking portion 1322 is separated from the unwinding shaft 11 to the position where the first locking portion 1322 is in anti-rotation engagement with the unwinding shaft 11, thereby preventing the unwinding shaft 11 from rotating. When the operating part 1311 of the control member 131 is subjected to an external force, the control member 131 overcomes the preload force of the third elastic member and rotates to the unlocked position under the action of the external force. At the same time, the first locking member 132, driven by the transmission part 1312 of the control member 131, overcomes the preload force provided by the fourth elastic member 135 and rotates to the position where the first locking part 1322 is separated from the unwinding shaft 11, so as to allow the unwinding shaft 11 to rotate. Optionally, the fourth elastic member 135 can be a torsion spring.

[0088] In a specific embodiment, the locking assembly 13 further includes a fifth elastic element 136, which is connected between the housing 10 and the second locking element 133. This fifth elastic element 136 provides a preload force to cause the second locking element 133 to rotate from the position where the second locking portion 1332 is separated from the take-up shaft 12 to the position where the two parts are in a non-rotational engagement. Thus, when the external force on the operating portion 1311 of the control element 131 disappears, under the preload force provided by the third elastic element, the control element 131 rotates from the unlocked position to the locked position. Simultaneously, under the preload force provided by the fifth elastic element 136, the second locking element 133 rotates from the position where the second locking portion 1332 is separated from the take-up shaft 12 to the position where the second locking portion 1332 is in a non-rotational engagement with the take-up shaft 12, thereby preventing the unwinding shaft 11 from rotating. When the operating part 1311 of the control member 131 is subjected to an external force, the control member 131 overcomes the preload of the third elastic member and rotates to the unlocked position under the action of the external force. At the same time, the second locking member 133, driven by the transmission part 1312 of the control member 131, overcomes the preload provided by the fifth elastic member 136 and rotates to the position where the second locking part 1332 is separated from the winding shaft 12, so as to allow the winding shaft 12 to rotate. Optionally, the fifth elastic member 136 can be a torsion spring.

[0089] Further, the first locking disc 110 coaxially fixed on the unwinding shaft 11 has a plurality of first locking recesses 1101 arranged at intervals in the circumferential direction. The first locking portion 1322 on the first locking member 132 can rotate to locking cooperation or separation with a corresponding first locking recess 1101. Thus, when the operation portion 1311 rotates with the control member 131 to the locking position under the action of the pre-tightening force provided by the third elastic member, the first locking member 132 rotates to the locking cooperation of the first locking portion 1322 and the corresponding first locking recess 1101 of the first locking disc 110 under the action of the pre-tightening force provided by the fourth elastic member 135, so as to prevent the rotation of the unwinding shaft 11. When the operation portion 1311 rotates with the control member 131 to the non-locking position under the action of the external force, the first locking member 132 rotates to the separation of the first locking portion 1322 and the corresponding first locking recess 1101 of the first locking disc 110, so as to allow the rotation of the unwinding shaft 11.

[0090] Further, the second locking disc 120 coaxially fixed on the winding shaft 12 has a plurality of second locking recesses 1201 arranged at intervals in the circumferential direction. The second locking portion 1332 on the second locking member 133 can rotate to locking cooperation or separation with a corresponding second locking recess 1201. Thus, when the operation portion 1311 rotates with the control member 131 to the locking position under the action of the pre-tightening force provided by the third elastic member, the second locking member 133 rotates to the locking cooperation of the second locking portion 1332 and the corresponding second locking recess 1201 of the second locking disc 120 under the action of the pre-tightening force provided by the fifth elastic member 136, so as to prevent the rotation of the winding shaft 12. When the operation portion 1311 rotates with the control member 131 to the non-locking position under the action of the external force, the control member 131 drives the second locking member 133 to rotate to the separation of the second locking portion 1332 and the corresponding second locking recess 1201 of the second locking disc 120, so as to allow the rotation of the winding shaft 12.

[0091] Specifically, when the moving seat 36 moves to the above-mentioned matched position, the operation portion 1311 of the control member 131 abuts against the device body (for example, the mounting frame 32), so that under the action of the abutting force (i.e. the above-mentioned external force acting on the operation portion 1311) applied to the operation portion 1311 by the device body, the operation portion 1311 rotates with the control member 131 to the non-locking position, thereby allowing the rotation of the unwinding shaft 11 and the winding shaft 12. When the moving seat 36 moves to the above-mentioned separated position, the operation portion 1311 of the control member 131 is separated from the device body (for example, the mounting frame 32) (i.e. the external force acting on the operation portion 1311 disappears), so that under the action of the pre-tightening force provided by the third elastic member, the operation portion 1311 rotates with the control member 131 to the locking position, thereby preventing the rotation of the unwinding shaft 11 and the winding shaft 12.

[0092] Please continue to refer to Figure 9 and Figure 10 As shown in FIG. 1, in some embodiments, the accommodation groove 101 has a closed end 103 and an opening 102 at two ends in the first direction X. The push band cassette 1 further comprises a guide band assembly comprising guide band posts mounted on the housing 10. The guide band posts are arranged on both sides of the opening 102 of the accommodation groove 101 in the second direction Y perpendicular to the first direction X, that is, the guide band posts are arranged on both sides of the opening 102 of the accommodation groove 101 in the second direction Y. The guide band posts are used for guiding the push band B to pass through, so that the push band B unwound from the unwinding shaft 11 is guided to the winding shaft 12 for winding, and the push band B passes through the opening 102 of the accommodation groove 101. In this way, the guide band posts for guiding the push band B are arranged on both sides of the opening 102 in the second direction Y, so that when the push head 31 moves to the push position along the first direction X to the opening 102, the push band B can be closely attached to the end of the push head 31 facing the slide seat 21, avoiding the phenomenon of wrinkling or tearing of the push band B.

[0093] In specific embodiments, the housing 10 comprises an unwinding area 104 and a winding area 105 located on both sides of the accommodation groove 101 in the second direction Y. The unwinding shaft 11 is located in the unwinding area 104, and the winding shaft 12 is located in the winding area 105.

[0094] The guide band posts comprise a first guide band post 141, a second guide band post 142, and a third guide band post 143 for guiding the push band B to pass through. The first guide band post 141 and the second guide band post 142 are arranged in the unwinding area 104 to guide the push band B unwound from the unwinding shaft 11 into the opening 102 of the accommodation groove 101. The third guide band post 143 is arranged in the winding area 105 to guide the push band B passing through the opening 102 of the accommodation groove 101 to the winding shaft 12 for winding. In this way, the push band B is guided by the first guide band post 141, the second guide band post 142, and the third guide band post 143, so that the push band B is stable, further avoiding the phenomenon of wrinkling or tearing of the push band B when the push band B is wrapped on the push head 31.

[0095] Further, the guide band posts further comprise a fourth guide band post 144 arranged in the unwinding area 104 and upstream of the first guide band post 141 and the second guide band post 142. The fourth guide band post 144 is used to guide the push band B unwound from the unwinding shaft 11 into the first guide band post 141 and the second guide band post 142, so that the guide band posts can smoothly enter between the first guide band post 141 and the second guide band post 142, and then pass through the opening 102 of the accommodation groove 101, further avoiding the phenomenon of wrinkling or tearing of the push band B when the push band B is wrapped on the push head 31.

[0096] In specific embodiments,Figure 10 In the illustrated embodiment, the push piece belt B output by the unwinding shaft 11 is first wound around the lower part of the fourth guide post 144, then passes between the first guide post 141 and the second guide post 142, further passes over the opening 102 of the accommodating groove 101, is wound around the lower part of the third guide post 143, and finally enters the winding shaft 12 to be wound.

[0097] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present disclosure.

[0098] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the patent right of the present application. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application.
