Problems solved by technology

The entire manual operation process is cumbersome, and only one slide can be processed at a time, which is inefficient, while biopsy pathology slides need to be processed and analyzed in time
[0003] The existing slide automatic staining device can basically process multiple slides at the same time, but most staining devices adopt the method of dipping, which has the problem of polluting the dye solution and affecting the detection results, and cannot perform targeted staining on pancreatic pathological slides. Sequential staining and washing

Embodiment 1

[0058] A device for sequential staining, washing, and air-drying of pathological slides, such as figure 1 As shown, it can be roughly divided into a moving mechanism 1, a pumping mechanism 2 and a casing 3.

[0059] Present embodiment kinematic mechanism 1 such as image 3 , Figure 4 As shown, a first motor 104 , a second motor 107 , a tilting pinion 106 , a tilting bull gear 105 and a translational gear 103 are installed on the moving mechanism frame 113 . Wherein, the tilt pinion 106 is connected with the second motor 107, and can rotate at a low speed under the control of the second motor 107; Turn at low speed. The large inclined gear 105 meshes with the small inclined gear 106, and the top surface of the large inclined gear 105 cooperates with the slide rail 108 on the lower end surface of the loading platform 101. At the same time, the rack 102 on the lower end surface of the loading platform 101 meshes with the translation gear 103 . Under the above-mentioned coop...

Embodiment 2

[0072] A sequential dyeing, washing, and air-drying device for pathological slides, comprising a movement mechanism 1, a pumping mechanism 2, and a box body 3. The motion mechanism is mainly composed of a loading table 101, a rack 102, a slide rail 108, a glass slide groove 109, a slope 110, a drain hole 111, a buckle 112, a first motor 104, a second motor 107, a motion mechanism frame 113, and a translation The gear 103, the inclined pinion gear 106, and the inclined large gear 105 constitute. The upper surface of the loading platform 101 is provided with a slide groove 109 , a slope 110 and a liquid drainage hole 111 . Both sides of the slide slot 109 are provided with buckles 112 for preventing the slide from moving. A rack 102 is provided on the lower surface of the loading platform 101, and is matched with a large inclined gear 105 through a groove (sliding rail 108). The rack 102 is meshed with the translation gear 103 , and the large inclined gear 105 is meshed with t...

Abstract

The invention relates to a device and a method for sequentially dyeing, washing and air-drying pathological slides. The device comprises a movement mechanism for moving the slides; the liquid pumping mechanism is used for spraying liquid onto the slide; the box body is used for storing liquid and air-drying the slide; the movement mechanism comprises a loading platform, a translation assembly for driving the loading platform to translate and a rotating assembly for driving the loading platform to rotate; the liquid pumping mechanism comprises a spraying head, a plurality of sets of liquid pumping assemblies for driving the spraying head to spray and an adjusting assembly for controlling the liquid pumping assemblies to start and stop; a plurality of liquid storage tanks are arranged on the box body, different dye liquids or clear water are contained in the liquid storage tanks, and each liquid storage tank is correspondingly connected with a set of liquid pumping assembly; the movement mechanism and the liquid pumping mechanism are arranged on the box body, and an air drying assembly is arranged on the box body. Compared with the prior art, the method provided by the invention can be used for rapid staining treatment evaluation of cell pathology after fine needle puncture under the guidance of a pancreatic lesion ultrasonic endoscope and in similar application scenes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sequential dyeing, washing, and air-drying device and method for pathological glass slides. Background technique [0002] At present, the assessment of cytopathological staining of pancreatic lesions after endoscopic ultrasonography-guided fine needle aspiration in hospitals mainly relies on manual staining, and the processing steps can be basically unified and simplified as follows: dyeing solution A washes and stains slides, and dye solution B rinses and stains slides , Rinse the slides with clean water to remove the floating color, and analyze them after drying. The entire manual operation process is cumbersome, and only one slide can be processed at a time with low efficiency, while biopsy pathology slides need to be processed and analyzed in time. [0003] The existing slide automatic staining device can basically process multiple slides at the same time, but most...
