Smear device for medical examination

By introducing a smearing and dispensing mechanism into the smearing device, and utilizing components such as triangular positioning plates, limiting grooves, electric telescopic rods, and guide wheels, the alignment of the upper and lower glass slides and the centered positioning of the droplet are achieved. This solves the problems of uneven smear edges and droplet overflow in the prior art, and improves the quality of smearing and ease of operation.

AI Technical Summary

Technical Problem

Existing medical testing smear devices cannot effectively maintain the edges of the upper and lower coverslips during smear preparation, and the dripping liquid is prone to overflow, affecting the quality of the smear.

Method used

A slide preparation device was designed, comprising a slide preparation mechanism and a slide-adjusting mechanism. Through components such as four triangular positioning plates, limiting grooves, lifting frames, electric telescopic rods, connecting frames, guide wheels, and rubber push rods, the device ensures that the liquid drop is centered and that the edges of the upper and lower slides are aligned when covering the slide. The precise alignment of the slides is achieved by the cooperation of the guide wheels and the rubber push rods.

Benefits of technology

It effectively solves the problems of uneven edges of the upper and lower glass slides and dripping, improves the quality and accuracy of the smear, and ensures the integrity of the smear and ease of operation.

Abstract

The utility model discloses a smear device for medical examination, which comprises a smear base, a smear mechanism and a shifting mechanism, the smear mechanism and the shifting mechanism are arranged on the top of the smear base and are distributed up and down, a connecting frame is fixedly arranged at the output ends of two first electric telescopic rods, rubber push rods are arranged on the two sides of the bottom of the connecting frame, and a positioning frame is fixedly arranged in the middle of the connecting frame. A plurality of guide wheels are rotationally connected to the top of the smear base at equal intervals and located in the middle positions of the two sides of the four triangular positioning sheets; according to the utility model, the middle position of the dropper is positioned through the positioning frame, so that the dropping liquid is propped against the middle position of the lower cover glass, the dropping liquid is not easy to extrude and flow to the outer side of the glass slide during later cover glass covering, and the edges of the glass slides are ensured to be neat after the glass slides are overlapped by matching the extrusion and pushing of the connecting frame and the rubber push rod and the positioning of the guide wheel and the triangular positioning frame; the problems that in the prior art, the edges of upper and lower slides cannot be guaranteed to be neat through mechanical smear, and liquid drops are likely to flow to the outer sides of the slides are solved.
