Description

Technical Field

[0001] The utility model relates to the technical field of medical detection instruments, in particular to a glass slide fixing device which is convenient to install. Background Art

[0002] Glass slides are one of the commonly used consumables in cytogenetic testing. They can be used for bone marrow and chromosome karyotype analysis of patients with blood tumors. They are also the most commonly used and important experimental supplies in fluorescence in situ hybridization (FISH) testing. One side of the glass slide is a white opaque area that can be used for simple recording of information, and the other side is a hybridization area that is used for denatured hybridization detection of probes. After washing, it can be directly observed under a fluorescence microscope. When observing the glass slide under a fluorescence microscope, the glass slide needs to be effectively fixed. The installation and disassembly of the glass slide is a major factor affecting the scanning efficiency of the fluorescence microscope.

[0003] The conventional manual installation of slides is inefficient, and improper operation can easily contaminate the slides. Therefore, with the improvement of the automation of microscopes, various devices for automatically loading and unloading slides have emerged. However, the existing slide fixing devices have a simple structure and cannot fix the slides well. The slides are easy to slide during testing, and the installation and removal of the slides are not convenient, which affects the efficiency of microscope observation of the slides. Utility Model Content

[0005] The utility model discloses a glass slide fixing device which is easy to install, comprising a base and a guide rail located on the upper part of the base and driven by a first motor, the guide rail being connected to a U-shaped base plate with a guide rail slider at the bottom, a double-headed lead screw with opposite thread directions being rotatably connected between the two ends of the U-shaped base plate and a guide rod being fixedly connected, the double-headed lead screw and the guide rod being connected to two lead screw sliders which are relatively arranged, the two lead screw sliders being respectively connected to a first clamping component and a second clamping component which have the same structure and are relatively arranged, the first clamping component and the second clamping component being driven by the double-headed lead screw to move toward each other to clamp and fix the glass slide.

[0006] As a further technical solution, the first clamping component includes a support plate connected to the lead screw slider and a fixed plate located on the upper part of the support plate, and the fixed plate has a clamping surface that is inclined downward to clamp the slide.

[0007] As a further technical solution, an elastic gasket is connected to the axis of the clamping surface, and the elastic gasket is bonded to the surface of the clamping surface.

[0008] As a further technical solution, the elastic gasket is made of rubber material or silicone material.

[0009] As a further technical solution, the support plate is provided with a plurality of limiting screw holes on one side of the clamping surface, and the limiting screw holes are provided with limiting blocks by bolts.

[0010] As a further technical solution, the double-ended lead screw is driven by a second motor located at one side of the U-shaped base plate or is driven by a handle.

[0011] The utility model has the beneficial effect that the slide fixing device of the utility model can directly place the slide between the first clamping part and the second clamping part which are arranged oppositely. The supporting plates which are arranged oppositely between the first clamping part and the second clamping part are used to receive the slide. Under the drive of the double-headed lead screw, the first clamping part and the second clamping part move toward each other. The clamping surfaces of the two fixing plates can directly clamp and fix the slide. The installation of the slide is particularly simple and convenient, which improves the observation efficiency of the microscope on the slide. Both the two clamping surfaces which are arranged oppositely are provided with elastic gaskets, which can prevent the slide from sliding while clamping the slide, thereby improving the stability of the slide clamping.
