Description

Smear device capable of adjusting thickness of blood cells Technical Field The invention relates to the technical field of smear, in particular to a smear device capable of adjusting blood cell thickness. Background Microscopic examination of blood smears is a fundamental method of blood cytology and is extremely widely used. The hand-operated push-plate is adopted to make, one drop of blood is taken and placed at one end of the slide, the slide is held by the left hand, one end of the push-plate with smooth edge is moved backwards from the front of the drop of blood to contact the drop of blood, and the drop of blood is scattered along the push-plate. Then the push plate and the slide glass keep a 30-45-degree included angle to move forward steadily, and the next thin blood film is reserved on the slide glass. The manual manufacturing mode has low efficiency and great labor intensity of medical workers. The invention of application publication number CN 115683776A discloses a blood smear device which can realize automatic smear, but the structure is complex, and the position of each time can not be kept consistent when medical care workers drip blood drops on a glass slide, and the final smear quality can be affected. Disclosure of Invention The invention aims to provide a smear device capable of adjusting blood cell thickness so as to solve the technical problems. In order to achieve the above purpose, the invention adopts the following technical scheme: the smear device capable of adjusting the thickness of blood cells comprises a slide placing seat, wherein the slide placing seat is provided with at least one slide placing groove for placing a slide, and the upper side of the slide is provided with a positioning groove; The pushing piece mechanism comprises a pushing piece seat and a driving mechanism, wherein at least one pushing piece is arranged on the pushing piece seat, the pushing piece is obliquely arranged relative to the slide placing groove, and the driving mechanism comprises a linear module and is used for driving the pushing piece seat to move along the length direction of the slide placing groove. Further, the positioning groove is a semicircular groove. Further, the positioning grooves are symmetrically arranged about a center line of the slide along the length. Further, one end of the slide placing groove is provided with an avoidance opening which is vertically communicated, and the tail part of the slide is positioned at the position of the avoidance opening. Further, the bottom of the pushing piece is a blood scraping part, and the upper part of the pushing piece is hinged to the pushing piece seat.
