Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a slide-pushing and staining instrument used in a hospital laboratory. Background Art

[0002] With the continuous development of social science and technology, medical equipment used in medical treatment has been improved, which has promoted the development of medical technology; among them, the push-slide stainer belongs to the category of medical equipment, and the push-slide stainer is used in the hospital laboratory. The push-slide stainer is a device used to stain tissue sections in clinical tests.

[0003] After searching, a patent document with patent announcement number CN212932123U discloses a fully automatic blood slide staining machine for medical examination. Aiming at the problem that the existing slide and staining are all operated manually, the work efficiency is low and the time is wasted, the following scheme is proposed, which includes a machine body, a main machine is arranged in the machine body, a lifting push rod is fixedly connected to the top of the machine body, a top plate is fixedly installed on the output shaft of the lifting push rod, two syringe mounting holes are symmetrically provided on the top plate, a blood sample syringe and a dye syringe are respectively installed in the two syringe mounting holes, and two infrared limit sensors are fixedly connected to the bottom of the top plate, and the two infrared limit sensors are respectively located near the blood sample syringe and the dye syringe. It is easy to use, and only needs to place the slide into the slide placement slot and start the servo motor to complete the dripping of blood and dye on the slide, which improves the work efficiency and saves time.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The existing fully automatic blood slide dyeing machine for medical examination injects blood sample and dye onto the slide through the provided blood sample syringe and dye syringe, and locks or unlocks the position of the blood sample syringe and dye syringe by turning different locking screws. However, it is necessary to turn multiple locking screws, which increases the number of working steps when disassembling and assembling the blood sample syringe and dye syringe, and increases the operation workload of medical staff;

[0006] 2. The existing fully automatic blood slide staining machine for medical testing adjusts the height of the top plate by controlling the lifting push rod, adjusts the height of the blood sample syringe and the dye syringe, and then controls the push rod motor to adjust the height of the thrust plate, so that the blood sample in the blood sample syringe drips onto the push plate, and in the same way, the dye in the dye syringe drips onto the push plate. It is impossible to apply pressure to the blood sample syringe and the dye syringe at the same time, which complicates the operating steps and makes the structure of the material extrusion component complicated and inconvenient to disassemble and assemble.

[0007] To this end, we provide a slide staining instrument for hospital laboratory to solve the above problems. Utility Model Content
