Problems solved by technology

Due to the shortcomings of artificially adding diluents, it is difficult to quantify and standardize, and the concentration of the suspension prepared after adding diluents is unknown, so the test results have certain chances and are difficult to reproduce repeatedly. Repeated tests on the same sample, the results vary greatly

Abstract

The invention relates to a novel quantitative dilution device. The novel quantitative dilution device comprises a frame, a conveying guide rail, a sensor, a dilution needle, a quantitative dilution pump, a diluent tank, a cross beam, a lifting plate, a rack, a gear, a lifting motor and a controller, wherein the sensor, a guide rail and the rack are mounted on the sides of the conveying guide rail; the lifting motor is mounted on the lifting plate and connected with the gear and the rack; the cross beam and the dilution needle are arranged on the top of the lifting plate; the dilution needle is sequentially connected with the quantitative dilution pump and the diluent tank in series through a guide pipe. The novel quantitative dilution device is capable of automatically carrying out quantitative dilution on samples and has the advantages of high automation degree, cleanness in operation, high biochemical safety and good operation environment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an automatic quantitative dilution device for experiments or inspections. Background technique [0002] In the inspection process of human or animal secretions, the inspectors will take some of the collected samples based on experience, add an appropriate amount of diluent to make a suspension, smear it on a glass slide and observe it under a microscope, and then record the observation As a result, an inspection report is issued. Due to the disadvantage of difficulty in quantification and standardization due to artificial addition of diluent, the concentration of the suspension prepared after adding diluent is unknown, so the test results have certain chances and are difficult to reproduce repeatedly. The results of repeated tests on the same sample vary greatly. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficienci...
