[0002] A glass slide is a glass or quartz slide used for observation under a microscope. When preparing a sample, target tissues such as cells / tissue sections are placed on the slide for observation. In the medical diagnostic process, pathological diagnosis is a crucial basis for doctors' pathological judgments. Pathological diagnosis primarily relies on the observation of the pathological morphology of the target tissues on the slide; therefore, the classification, transportation, and distribution of slides carrying target tissues are indispensable parts of the pathological diagnostic process. Currently, existing techniques involve manually marking slides to facilitate subsequent classification, transportation, and location. However, with the increasing number of slides requiring examination in domestic hospitals, the traditional manual marking method is prone to errors, affecting subsequent classification and sorting. Furthermore, the manual marking workload is enormous and inefficient.

Detailed Implementation

[0028] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] like Figures 1-5As shown, this utility model provides a slide marking device, which includes a base plate 100 that provides a mounting base for other components. A linear motion module and an inkjet printing module 300 are both mounted on the base plate 100. In order to control the movement distance of the linear motion module according to the position of the target tissue on the slide, the linear motion module is electrically connected to a slide positioning and scanning device (not shown). The slide positioning and scanning device is prior art, and its specific structure will not be described here. It can scan the position coordinates of the target tissue on the slide, and then control the movement distance of the linear motion module according to the position coordinate information of the target tissue.

[0030] The linear motion module includes a linear drive motor 401, a synchronous pulley set 402, a linear guide rail 403, and a load-bearing slider 404. The synchronous pulley set 402 is existing technology and includes a drive wheel 4021, an idler wheel 4022, an idler wheel fixing base 4024, and a synchronous belt 4023 fitted on the drive wheel 4021 and the idler wheel 4022. The idler wheel 4022 is tactilely connected to the idler wheel fixing base 4024.

[0031] A motor mounting plate 101 is installed on one side of the base plate 100 along the Y direction. The motor mounting plate 101 has a through hole. The linear drive motor 401 is located on one side of the base plate 100 along the Y direction, and the fixed end of the linear drive motor 401 is connected to the motor mounting plate 101 by bolts. The driving end of the linear drive motor 401 passes through the through hole on the motor mounting plate 101 and drives the drive wheel 4021 in the synchronous belt pulley set 402. The idler wheel fixing base 4024 is set on the same side as the drive wheel 4021 and is installed on the other end of the base plate 100 away from the linear drive motor 401. The linear guide rail 403 is installed on the base plate 100 along the X direction and is parallel to the length direction of the synchronous belt 4023. A guide rail slider is slidably connected to the linear guide rail 403.

[0032] The supporting slider 404 is a long rectangular block. Both ends of the supporting slider 404 are recessed to form a stepped surface, and the middle part of one of the stepped surfaces is concave to form a synchronous belt groove 4041. The supporting slider 404 is set perpendicular to the synchronous belt and the linear guide rail 403. A section of the synchronous belt 4023 is placed in the synchronous belt groove 4041. In order to maintain the relative fixed connection between the synchronous belt and the supporting slider 404, a synchronous belt pressure plate 405 is connected to the stepped surface above the synchronous belt groove 4041 by bolts. The middle end of the supporting slider 404 is fixed to the guide rail slider on the linear guide rail 403. A glass slide tray 200 is connected to the stepped surface of the supporting slider 404 at the end away from the synchronous belt groove 4041 by bolts.

[0033] The slide tray 200 is a long rectangular strip, parallel to the linear guide rail 403. One end of the slide tray 200 is a mounting surface, which is mounted on the stepped surface of the support slider 404, so that the slide tray 200 and the support slider 404 are on the same horizontal plane. The other end of the slide tray 200 away from the support slider 404 is recessed to form a tray groove 201. The tray groove 202 is rectangular, with an opening at the end of the tray groove 201 away from the support slider 404, and baffles on the other three sides. The length and width dimensions of the tray groove 202 are compatible with the length and width dimensions of the slide 000. In use, the slide 000 is placed in the tray groove 202 along its length. In order to avoid contamination of the tissue target on the slide 000, the slide 000 is placed in the tray groove 202 with the reverse side facing up and the front side coated with the tissue target facing up.

[0034] Preferably, to facilitate the placement and removal of the glass slide 000, the tray groove 201 has an opening at the end away from the bearing slider 404, and a notch 202 is formed by the inward retraction towards the bearing slider 404. In this utility model, the notch 202 is an arc shape.

[0035] When the linear drive motor 401 starts, it drives the drive wheel 4021 to rotate. The drive wheel 4021 drives the idler wheel 4022 to rotate synchronously via the synchronous belt 4023. At the same time, the carrying slider 404 connected to the synchronous belt 4023 moves linearly along the linear guide rail 403. Preferably, to prevent the carrying slider 404 from disengaging from the linear guide rail 403 when it moves linearly away from the linear drive motor 401, or to position the glass slide 000, the synchronous belt pressure plate 405 is provided with a limiting plate 406 on the side away from the linear guide rail 403, and the idler wheel fixing base 4024 is fixed with a connecting plate 501 on the side away from the linear guide rail 403. A limit sensor 500 is provided on the outer side of the connecting plate 501. When the limiting plate 406 on the carrying slider 404 slides to the limit sensor 500 along with the synchronous belt 4023, the carrying slider 404 stops.

[0036] To mark the location of the target tissue on the slide 000, a mounting bracket 600 is provided on the base plate 100. An inkjet printing module 300 is installed on the mounting bracket 600. The inkjet printing module 300 is centrally located between the linear drive motor 401 and the idler wheel base, and is located above the support slider 404 and the slide tray 200. The inkjet printing module 300 is existing technology and is used to mark the slide with ink. The color or shape of the ink can be selected and changed according to different needs.

[0037] The mounting bracket 600 is installed on the base plate 100 and located on the side of the linear guide 403 away from the synchronous belt 4023. The mounting bracket 600 is rectangular, and its bottom surface near the end of the carrying slider 404 and the slide tray 200 is tapered upwards, forming a passageway 602 between its bottom surface and the base plate 100, allowing the carrying slider 404 to drive the slide tray 200 to slide back and forth through the passageway. A rectangular cutout 601 is provided on the mounting bracket 600, corresponding to the passageway 602. The length of the cutout 601 is not less than the width of the slide 000. The inkjet printing module 300 is mounted on the mounting bracket 600, and the printhead 300 on the inkjet printing module 300... Located above the cutout section 601, the printhead 301 is rectangular, and its length direction is perpendicular to the length direction of the slide 000 on the slide tray 200. The length dimension of the printhead 301 is basically the same as the width dimension of the slide 000. In this way, when the inkjet printing module 300 sprays ink onto the slide 000 through the printhead 301, the reverse side of the target tissue on the slide 000 has obvious inkjet markings along its width direction. This allows the slide to be quickly classified, transported, and located according to different colors or marking patterns on the slide 000. At the same time, it also facilitates the quick location and detection of the target tissue on the slide during microscopic observation based on the obvious inkjet markings.

[0038] The operation process of this utility model is as follows:

[0039] First, such as Figure 1 As shown, the carrier slider 404 and slide tray 200 move towards the idler wheel fixed base 4024 under the drive of the linear motion module. When the limit sheet metal 406 touches the limit sensor 500, the carrier slider 404 and slide tray 200 stop. The slide to be marked 000 is placed with the reverse side facing down into the tray groove 201 on the slide tray 200 along its length. At this time, the slide reading positioning and scanning device scans the fine coordinate position of the target tissue on the slide 000 (the slide has high light transmittance). (Placing it on the reverse side does not affect scanning). The slide positioning and scanning device will control the drive stroke of the slide positioning and scanning device to move according to the coordinate information obtained from the scan. The slide carrier 404 and the slide tray 200 move towards the inkjet printing module 300 under the drive of the linear motion module. When the slide 000 on the slide tray 200 moves to the passage 602, it continues to pass through the passage 602 until the position of the target tissue on the slide 000 corresponds to the printhead 301 above the cutout 601. Figure 4 As shown, the linear motion module stops driving, the slide 000 on the slide tray 200 also stops moving, and the printhead 301 on the inkjet printing module 300 sprays ink onto the slide 000, marking is complete.

[0040] When it is necessary to remove the marked slide 000, the linear movement module is activated, which moves the slide tray 200 and the slide 000 away from the passage channel 602. Once the slide is out of the obstruction range of the passage channel 602, the slide 000 can be removed.

[0041] The above describes a scenario where the glass slide 000 is placed on the slide tray 200 with the reverse side facing up for inkjet marking of target tissues on the slide. This invention is also applicable to printing label information on glass slides, or printing desired information on the head of the glass slide, and can be placed on either side.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
