Full-automatic general analyzer control circuit

Abstract

The invention relates to a full automatic normal analyzer control circuit which belongs to the field of medical detection. A circuit part of the invention mainly consists of an MCU, a motor drive circuit, a peristaltic pump, a photosensitive resister, an amplification circuit, a solenoid valve, a work indicator light, a key, an amplification circuit, a photosensitive cell, a PC and a MAX232. The programmer design cycle of the invention is that: start a machine, initialization of the system, wait online, and self-inspection of the instrument after successful online. The solenoid valve has self-inspection orderly and can inspect by closing the machine if any difference is found. After self-inspection, the instrument starts cleaning procedure to clean a pipeline system. After cleaning, the instrument is on a standby state, waiting for an order, to enter into the procedures of cleaning, mixing evenly, sample introduction, setting of parameters, automatic operation and manual operation. Being used for the normal analyzer, the invention can greatly reduce the error by a human factor, improve the repeatability of detection obviously and ensure the quality control of the medical normal detection.

Description

technical field [0001] The invention relates to a control circuit of a fully automatic conventional analyzer, specifically a control circuit of a fully automatic conventional analyzer based on a single-chip microcomputer and assembly language. Background technique [0002] For a long time, many processes of medical testing, such as filtration, cleaning, centrifugation, etc., are mostly done manually, which not only has complicated procedures, but also has low work efficiency. Taking the routine detection of stool as an example, stool is the residual product after food is digested and absorbed in the body. ②catabolites, such as indigo substrate, fatty acid, and gas; ③secretions from the stomach, intestines, and liver, such as bile pigments, enzymes, mucus, and inorganic salts; ④mucosal epithelial cells exfoliated from the digestive tract; ⑤Bacteria are mainly Escherichia coli, enterococcus and some passing bacteria; ⑥Moisture. When the body has digestive dysfunction, and th...

Problems solved by technology

However, due to the particularity of stool samples, the test results of the same sample may vary significantly

In manual operation, due to the different techniques of the operators and the inconsistency of the amount of saline added, the reported results have large errors, and the remnants of the microscope inspection need to be disinfected and washed in a separate container. Improper operation may cause damage to the laboratory environment. and staff pollution, and even cause cross-infection accidents
