Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and particularly to a smear pushing assembly and a smear pushing device. Background Art

[0002] Microscopic examination of blood smears is a basic method for blood cytology examination, especially valuable for the diagnosis of various blood diseases, and is widely used in clinical examinations.

[0003] The production of blood smears requires dropping a blood sample onto the surface of a carrier, and then pushing the sample away in a uniform distribution through a smear pushing operation, so that blood cells and the like are distributed as single layers as much as possible, facilitating observation and diagnosis. During the working process, the smear pushing head first presses down tightly against the surface of the carrier, and then while maintaining the downward pressure, the carrier and the smear pushing head move relative to each other to achieve the pushing of the sample. Among them, the angle between the smear pushing head and the carrier has an important impact on the quality of the blood smear. However, to adjust the angle of the smear pushing head and also to achieve the lifting of the smear pushing head, the existing devices have complex structures, large occupied spaces, cannot meet the needs of miniaturization of clinical instruments, and are also prone to failures.

[0043] As shown in the figure, an embodiment of the present invention provides a push piece assembly, including: a push head 1, a sliding plate 2, a deflection slider 3, a lifting drive mechanism 4, a deflection drive mechanism 5, and a back plate 6.

[0044] The push head 1 is fixedly connected to the sliding plate 2.

[0045] The sliding plate 2 is slidably engaged with the deflection slider 3.

[0046] The lifting drive mechanism 4 and the deflection drive mechanism 5 are respectively arranged on the back plate 6, and the lifting drive mechanism 4 drives the sliding plate 2 to lift relative to the deflection slider 3, and the deflection drive mechanism 5 drives the deflection slider 3 to rotate to drive the sliding plate 2 and the push head 1 to rotate.

[0047] This application provides a push piece assembly, including: a push head 1, a sliding plate 2, a deflection slider 3, a lifting drive mechanism 4, a deflection drive mechanism 5, and a back plate 6. The push head 1 is fixedly connected to the sliding plate 2; the sliding plate 2 is slidably engaged with the deflection slider 3; the lifting drive mechanism 4 and the deflection drive mechanism 5 are respectively arranged on the back plate 6, and the lifting drive mechanism 4 drives the sliding plate 2 to lift, thereby driving the push head 1 to lift; and the deflection drive mechanism 5 drives the deflection slider 3 to rotate to drive the sliding plate 2 and the push head 1 to rotate, thereby adjusting the deflection angle of the push head 1. The push piece assembly provided by this application can realize the lifting and angle adjustment of the push head 1 by using the driving of the lifting drive mechanism 4 and the deflection drive mechanism 5 and cooperating with the mutual relationship among the push head 1, the sliding plate 2, and the deflection slider 3. It has a compact structure, high reliability, and small occupied space.

[0048] Specifically, for the push piece assembly provided by this application, the lifting or deflection action process is as follows:

[0049] When it is necessary to lift or lower the push head 1, the deflection drive mechanism 5 does not work, and the position of the deflection slider 3 connected to it by power remains unchanged; at this time, the lifting drive mechanism 4 works to drive the sliding plate 2 to generate relative sliding with the deflection slider 3, thereby driving the push head 1 fixedly connected to the sliding plate 2 to lift or lower.

[0050] When the deflection angle of the film pusher 1 needs to be changed, the lifting drive mechanism 4 does not work, and the height of the lifting plate 2 in the vertical direction remains unchanged; at this time, the deflection drive mechanism 5 works, driving the deflection slider 3 to rotate, and the sliding plate 2 that slides with it will also be driven to rotate by the rotational force, so that the angle of the film pusher 1 fixedly connected to the sliding plate 2 also changes.

[0051] In the actual working process, the film pushing head 1 is usually driven down first until it touches the carrier (usually touches the carrier through the film pushing belt), and then the film pushing head 1 is driven to deflect, so that the angle of the film pushing head 1 relative to the carrier (i.e., the film pushing angle α) changes, thereby better realizing the film pushing operation.

[0052] In the present application, the deflection slider 3 and the sliding plate 2 can slide relative to each other, and both can rotate at the same time. This can be achieved by controlling the sliding direction between the deflection slider 3 and the sliding plate 2 to be roughly close to the vertical direction, and the limit between the deflection slider 3 and the sliding plate 2 to be roughly on both sides of the horizontal direction.

[0053] In the present application, the function of the carrier is to carry the sample. The carrier can be a glass slide, a counting plate, etc., and the sample can be blood, cerebrospinal fluid, leucorrhea, etc.

[0054] Preferably, the lifting drive mechanism 4 includes a lifting power source 41 and a lifting transmission member 42.

[0055] The film pusher 1 is fixedly connected to the sliding plate 2 via a connecting rod 11.

[0056] The lifting transmission member 42 limits the upper and lower parts of the connecting rod 11 and is lifted and lowered under the drive of the lifting power source 41 .

[0057] The lifting drive mechanism 4 specifically includes a lifting power source 41 and a lifting transmission member 42. The film pusher 1 is fixedly connected to the sliding plate 2 through an extended connecting rod 11, so that the lifting transmission member 42 can limit the upper and lower positions of the connecting rod 11. At the same time, the lifting transmission member 42 is lifted and lowered under the drive of the lifting power source 41, thereby driving the connecting rod 11 to rise or fall.

[0058] Preferably, a lifting seat 12 is provided on the outer periphery of the connecting rod 11, and a bearing is provided between the lifting seat 12 and the connecting rod 11;

[0059] The lifting transmission member 42 is sleeved on the outer periphery of the lifting seat 12 .

[0060] The lifting transmission member 42 can limit the connection rod 11 by providing a limiting protrusion on the lifting transmission member 42, or by digging a hole in the middle of the lifting transmission member 42 for the connection rod 11 to pass through.

[0061] Preferably, a lifting seat 12 is further provided on the outer periphery of the connecting rod 11, and a bearing is provided between the connecting rod 11 and the lifting seat 12, and the two can rotate relative to each other; at the same time, the lifting transmission member 42 is sleeved on the outer periphery of the lifting seat 12, and when the lifting transmission member 42 lifts, it drives the lifting seat 12 to lift. During this process, even if the angles of the deflection slider 3 and the sliding plate 2 relative to the vertical direction change, the relative rotation between the lifting seat 12 and the connecting rod 11 can be used for buffering during the lifting process, so that the lifting transmission member 42 can be tightly clamped with the outer periphery of the lifting seat 12, avoiding excessive gaps and resulting in the lifting drive mechanism 4 being unable to accurately control the lifting distance of the pushing head 1.

[0062] The number of bearings provided between the connecting rod 11 and the lifting seat 12 is preferably 2-8, and more preferably 2-4.

[0063] Preferably, the lifting transmission member 42 is in threaded cooperation with the output shaft of the lifting power source 41, and the lifting transmission member 42 is also slidably connected to the back plate 6 through a first lifting guide rail slider mechanism 43.

[0064] Preferably, the lifting transmission member 42 is in threaded cooperation with the output shaft of the lifting power source 41 to convert the force output by the lifting power source 41 into linear movement; the lifting transmission member 42 is also slidably connected to the back plate 6 through a first lifting guide rail slider mechanism 43 to further limit the moving direction of the lifting transmission member 42 and avoid deviation.

[0065] The lifting power source 41 is preferably a motor, which is fixed to the back plate 6 so that the output shaft is vertically downward.

[0066] Preferably, a mounting plate 7 for mounting the push film cassette A is further provided, the lifting transmission member 42 is slidably connected to the mounting plate 7 through a second lifting guide rail slider mechanism 44, and the mounting plate 7 has a cavity for the pushing head 1 to pass through and move.

[0067] More preferably, a mounting plate 7 for mounting the push film cassette A is further provided, and the mounting plate 7 and the back plate 6 sandwich the sliding plate 2, the deflection slider 3, the lifting drive mechanism 4, the deflection drive mechanism 5, etc. in the middle. And a second lifting guide rail slider mechanism 44 is also provided between the mounting plate 7 and the lifting transmission member 42 to further guide the movement of the lifting transmission member 42 in cooperation with the first lifting guide rail slider mechanism 43.

[0068] The mounting plate 7 has a cavity for the pushing head 1 to pass through and move, and will not hinder the cooperation between the pushing head 1 and the push film cassette A and the contact between the pushing head 1 and the carrier.

[0069] A first lifting guide rail slider mechanism 43 is arranged between the back plate 6 and the lifting transmission member 42. The guide rail part of the guide rail slider mechanism can be arranged on the back plate 6, or the slider part of the guide rail slider mechanism can be arranged on the back plate 6. Similarly, the guide rail part and the slider part of the second lifting guide rail slider mechanism 44 arranged between the mounting plate 7 and the lifting transmission member 42 can also be flexibly arranged according to needs.

[0070] Preferably, the deflection driving mechanism 5 comprises a deflection power source 51 and a deflection transmission member 52.

Through the relative rotation between the deflection slider 3 and the deflection transmission member 52, the force of the deflection power source 51 driving the deflection transmission member 52 to move linearly is converted to drive the deflection slider 53 to rotate a certain angle, thereby driving the sliding plate 2 that slides with it to rotate an angle, thereby changing the position of the film pusher 1.

[0074] The number of bearings provided between the deflection transmission member 52 and the support rod 31 is preferably 2-8, more preferably 2-4.

[0075] In this application, lifting refers to movement along the X-axis; translation refers to movement along the Y-axis, and the X-axis and the Y-axis are perpendicular to each other. In addition, the film pusher 1 can also swing along the Z-axis, so that one end of it will not contact the carrier in the Z-axis direction and the other end will not be lifted up. The film pusher 1 can be passively swung along the Z-axis by being hinged with the connecting rod 11 and elastic members are respectively provided at both ends of the hinge axis to provide pre-pressure. For example, the structure described in the applicant's prior patent CN217819594U can be used to achieve this.

[0076] The Z axis is perpendicular to the X axis and the Y axis.

[0077] Preferably, the deflection transmission member 52 is threadedly matched with the output shaft of the deflection power source 51 .

[0078] Preferably, the deflection transmission member 52 is threadedly matched with the output shaft of the deflection power source 51 to convert the force output by the deflection power source 51 into linear movement, which is easy to assemble and has high reliability.

[0086] The carrier moving mechanism 8 is used to drive the carrier to move.
