Problems solved by technology

At present, blood smears are still made manually, which is relatively inefficient.
The carelessness or misoperation of the medical staff will lead to non-standard production of blood smears, which cannot effectively form a single cell layer for inspection, or cause cells to break due to uneven force of pushing the smear, which will have a greater subjective impact

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 and figure 2 As shown, an automatic peripheral blood film pushing device has a bottom plate 1 on which a sliding table base 2 and a lead screw 3 are installed. An angle slide 4 and a glass slide seat 5 are successively installed on the slide base 2, and the slide glass 23 is placed on the slide glass seat 5, and the precision angle slide 4 can be used to adjust the angle to ensure that the slide glass 23 is in the The horizontal state can effectively reduce the levelness error of the slide glass 23 caused by the processing error.

[0019] One end of the leading screw 3 is connected with the upper motor 6 in the vertical direction, the guide rail base plate 7 is connected with the leading screw 3, and the rotation of the stepper motor is converted into linear motion by using a rolling screw, so that the guide...

Abstract

The invention relates to an automatic peripheral blood pushing device, which can achieve regular and standard blood smears by controlling parameters having directly affection on quality of the blood smears during a pushing process. Particularly, the automatic peripheral blood pushing device can control three degrees of freedom, utilizes a horizontal motor to control inclined included angle between a push slide and a glass slide, and utilizes a left motor to drive a synchronous belt pulley to complete blood pushing action, and adjusts speed and acceleration of the push slide by controlling rotation speed and acceleration of the left motor so as to control lengths of formed blood films. A clearance between the push slide and the horizontal glass slide is adjusted by utilizing an upper motor to drive a lead screw so as to control thicknesses of the formed blood films. Angle, speed and acceleration of the push slide, lengths of blood films and a clearance between the push slide and the glass slide can be adjusted by controlling running of the three motor, thereby manufacturing regular and stand blood smears with different thicknesses.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an automatic blood pushing tablet preparation device. Background technique [0002] In recent years, with the advancement of science and technology and the widespread use of computers, a large number of automated instruments have been introduced into blood testing in clinical laboratories, making the processing of clinical specimens easier, faster and more accurate in laboratories, effectively reducing the workload of inspectors. Improved work efficiency. [0003] At present, clinical automated hematology analyzers are widely used, and most of these instruments obtain classification results by measuring changes in cell resistance. Experiments have shown that blood analyzers cannot distinguish naive, eosinophilic, basophilic, and monocytes, let alone the toxic changes of heterolymph and nucleated red blood cells and neutrophils. Some small granulocytes are sometimes ...
