Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for individually releasing blood smear staining boxes based on an electromagnet. Background Art

[0002] In a fully automatic smear staining machine, the staining device is a key component, which determines the staining quality of blood smears. There are two common staining methods for traditional staining devices: multi-slice staining method and single-slice staining method. Compared with the multi-slice staining method, the single-slice staining method has the advantages of less time consumption and better consistency of staining effect.

[0003] The single-slice staining method is to place the blood smear in a separate staining box for staining. Each staining pool contains only one blood smear. The volume of the staining box is small enough, and only a small amount of dye needs to be added each time to effectively stain the blood smear.

[0004] For the staining devices of the traditional single-slice staining method, some staining boxes cannot be recycled, some have complex structures, large volumes and low working efficiency. To realize the recycling of staining boxes, it is necessary to block and release the staining boxes at different staining stations to realize the reagent filling and emptying of the staining boxes. When the staining box is filling or emptying the reagent, other staining boxes cannot affect it. At the same time, after staining, it is necessary to realize the individual release and blocking of the staining boxes. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for individually releasing blood smear staining boxes based on an electromagnet, which solves the technical problem that the staining boxes of the existing staining devices of the single-slice staining method cannot be individually blocked and released at different staining stations, so that the recycling of the staining boxes cannot be realized.

The rotary transmission mechanism, the mechanism for individually releasing staining boxes, and the mechanism for automatically filling and discharging reagents are all installed on the upper surface of the bottom plate. A number of the single-slice staining boxes are placed on the rotary transmission mechanism. A mechanism for individually releasing staining boxes is arranged at each staining station of the rotary transmission mechanism. The rotary transmission mechanism is used for rotary cyclic transmission of the single-slice staining boxes. The mechanism for individually releasing staining boxes is used for individually releasing and blocking the single-slice staining boxes. The mechanism for automatically filling and discharging reagents is used for filling or emptying reagents for the single-slice staining boxes.

The linear guide rails are arranged inside the bracket, and the number of the linear guide rails is two. The first blocking rod and the second blocking rod are respectively installed on the two linear guide rails.

[0008] Among them, the mechanism for releasing the staining boxes one by one further includes an electromagnet, and the electromagnet is arranged on one side of the bracket close to the linear guide rails.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0020] First embodiment:

[0021] Please refer to Figures 1 to 3 wherein Figure 1 is a schematic structural diagram of the overall blood smear staining box one-by-one release device based on the electromagnet 202 according to the first embodiment of the present utility model, Figure 2 is a schematic structural diagram of the staining box one-by-one release mechanism 2 according to the first embodiment of the present utility model, Figure 3 is a schematic structural diagram of the single-piece staining box 4 according to the first embodiment of the present utility model. The present utility model provides a blood smear staining box one-by-one release device based on the electromagnet 202, which includes a bottom plate 5, a rotary conveyor mechanism 1, a staining box one-by-one release mechanism 2, a reagent automatic filling and discharging mechanism 3, a single-piece staining box 4, and a blood smear 6. The staining box one-by-one release mechanism 2 includes a bracket 201, a linear guide rail 203, a first blocking rod 204, a second blocking rod 205, an electromagnet 202, a magnet 206, a connecting rod 207, and a return spring 208.

[0022] In this embodiment, the present utility model drives the single-piece staining box 4 to perform a rotary motion through the rotary conveyor mechanism 1. During the rotary motion of the single-piece staining box 4, the single-piece staining box 4 is released and blocked one by one through the staining box one-by-one release mechanism 2, so that the reagent automatic filling and discharging mechanism 3 can be used to fill or empty the reagent for the single-piece staining box 4, and further realize the recycling of the single-piece staining box 4, solving the technical problem that the staining box of the existing staining device for the single-piece staining method cannot be blocked and released one by one at different staining stations, and thus the recycling of the staining box cannot be realized.

[0023] Among them, the rotary transfer mechanism 1, the dyeing cassette one-by-one release mechanism 2, and the reagent automatic filling and discharging mechanism 3 are all installed on the upper surface of the bottom plate 5. A number of the single-piece dyeing cassettes 4 are placed on the rotary transfer mechanism 1. A dyeing cassette one-by-one release mechanism 2 is provided at each dyeing station of the rotary transfer mechanism 1. The rotary transfer mechanism 1 is used for rotary cyclic transfer of the single-piece dyeing cassettes 4. The dyeing cassette one-by-one release mechanism 2 is used for one-by-one release and blocking of the single-piece dyeing cassettes 4. The reagent automatic filling and discharging mechanism 3 is used for filling or emptying reagents into the single-piece dyeing cassettes 4.

[0024] Secondly, the linear guide rail 203 is arranged inside the bracket 201. The number of the linear guide rails 203 is two. The first blocking rod 204 and the second blocking rod 205 are respectively installed on the two linear guide rails 203. The electromagnet 202 is arranged on one side of the bracket 201 close to the linear guide rail 203.

[0025] Thirdly, the magnet 206 is fixed on the second blocking rod 205. The connecting rod 207 is arranged between the first blocking rod 204 and the second blocking rod 205 and is used for connecting the first blocking rod 204 and the second blocking rod 205. One end of the return tension spring 208 is fixed on the bracket 201, and the other end of the return tension spring 208 is fixed on the second blocking rod 205.

[0026] Meanwhile, one blood smear 6 is accommodated inside the box body 401 of each single-piece dyeing cassette 4.

[0027] In addition, one iron cylinder 402 is press-fitted on each side of the box body 401 of each single-piece dyeing cassette 4 and is used for adsorbing together with the magnet 206 to achieve the straightening of the single-piece dyeing cassette 4.

[0028] Finally, a convex stop piece 401a is designed on the box body 401 of each single-piece dyeing cassette 4 and is used for triggering a position sensor to judge whether there is a single-piece dyeing cassette 4 at the dyeing station.

[0029] When using a blood smear dyeing cassette one-by-one release device based on the electromagnet 202 in this embodiment, the rotary transfer mechanism 1, the dyeing cassette one-by-one release mechanism 2, and the reagent automatic filling and discharging mechanism 3 are installed above the bottom plate 5. Among them, a number of placing grooves are provided on the rotary transfer mechanism 1. The single-piece dyeing cassette 4 is placed in each placing groove of the rotary transfer mechanism 1. One blood smear 6 is accommodated inside the box body 401 of each single-piece dyeing cassette 4. A plurality of dyeing stations are provided on the rotary transfer mechanism 1 of the bottom plate 5, and a dyeing cassette one-by-one release mechanism 2 is provided at each dyeing station.

[0030] When there is no such single-piece staining cassette 4 on the staining station or the reagent filling and discharging are not completed, the staining cassette one-by-one release mechanism 2 is in a blocking state. At this time, the electromagnet 202 is not energized. Under the action of the return tension spring 208, the second blocking rod 205 equipped with the magnet 206 is in the blocking state at the lowest end. At this time, the single-piece staining cassette 4 is allowed to perform a rotary circular motion on the rotary transfer mechanism 1. When a single-piece staining cassette 4 is conveyed to the corresponding staining station on the rotary transfer mechanism 1 during the circular motion, the single-piece staining cassette 4 will be blocked by the second blocking rod 205. At the same time, the magnet 206 will attract the iron cylinder 402 on the single-piece staining cassette 4 to achieve straightening of the single-piece staining cassette 4. By straightening the single-piece staining cassette 4 at the staining station, the normal lifting of the liquid adding needle can be ensured without being blocked.

[0031] While straightening the single-piece staining cassette 4, the raised baffle 401a of the single-piece staining cassette 4 will trigger the position sensor, so that the position sensor will judge that there is a single-piece staining cassette 4 on the staining station. At this time, the position sensor will trigger the reagent automatic filling and discharging mechanism 3, so that the reagent filling or emptying can be completed through the reagent automatic filling and discharging mechanism 3. After the reagent is filled or emptied, the electromagnet 202 is energized, so that the electromagnet 202 will drive the first blocking rod 204 to move downward after being energized. At the same time, under the action of the connecting rod 207, the second blocking rod 205 will move upward, so as to realize the alternating up and down movement of the first blocking rod 204 and the second blocking rod 205, and realize the one-by-one release and blocking of the single-piece staining cassette 4.

[0032] When the single-piece staining cassette 4 on the staining station leaves the staining station under the circular motion of the rotary transfer mechanism 1, the single-piece staining cassette 4 in front of the staining station will be blocked by the second blocking rod 205. When the single-piece staining cassette 4 completely leaves the staining station, the electromagnet 202 will be powered off. Under the action of the return tension spring 208, the second blocking rod 205 will move downward. At the same time, the first blocking rod 204 will move upward, so as to convey the single-piece staining cassette 4 in front of the staining station to the staining station. After completing the same action process as the previous single-piece staining cassette 4, it is released, realizing the simultaneous linkage of the release and blocking of the single-piece staining cassette 4, so as to facilitate releasing one single-piece staining cassette 4 while blocking the next single-piece staining cassette 4.

[0033] In summary, in the present utility model, the first blocking rod 204 and the second blocking rod 205 are respectively installed on the two linear guide rails 203, and the first blocking rod 204 and the second blocking rod 205 are connected by the connecting rod 207, so that the first blocking rod 204 and the second blocking rod 205 can be driven by the electromagnet 202 to move up and down alternately, thereby realizing the individual release and blocking of the single-piece staining cassette 4, and further realizing the filling or emptying of the reagent in the single-piece staining cassette 4, and realizing the recycling of the single-piece staining cassette 4, solving the technical problem that the staining cassette of the existing staining device for the single-piece staining method cannot be individually blocked and released at different staining stations, and thus the recycling of the staining cassette cannot be realized.

Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
