Description
Technical field
The utility model relates to a kind of full application of brake blood analyser control circuit, belongs to the medical science detection range.
Background technology
Blood is unique medium of matter transportation in the perfect aspect, so blood has indispensable status in human body.The working condition of each organ of inside of human body also embodies to some extent with some materials what of content in blood.Therefore, blood analysis also is a routine inspection in hospital always.But filtrations such as many processes of hospital's blood testing, cleaning, centrifugal etc. have manually more and finish for a long time.Not only formality is numerous and diverse, and effect is low.In manual operations, because operating personnel's gimmick is different and the disunity of reagent dosage, so resultant error is bigger, and misoperation may cause the pollution to experimental situation and staff, even causes the cross-infection accident.
The utility model content
At above-mentioned deficiency, the utility model patent provides a kind of full application of brake blood analyser control circuit, and utility model is applied to can significantly reduce the error that human factor causes in the conventional blood analyser, obviously improved the repeatability that detects, for the quality of medical blood analysis provides guarantee.
The utility model patent solves the technical scheme that its technical matters takes:
A kind of full application of brake blood analyser control circuit, mainly by MCU, MAX232 chip, Serial Port Line, computer, data acquisition circuit, amplifying circuit, photoelectric cell, motor-drive circuit, motor and peristaltic pump, button and pilot lamp, temperature sensor and heater circuit are formed, and described MCU output terminal is connected with peristaltic pump with motor by motor-drive circuit; Simultaneously, the output terminal of MCU also is connected with heater circuit, and heater circuit is connected with temperature sensor, and temperature sensor is connected with the input end of MCU; Button and pilot lamp also are connected with the MCU output terminal; Photoelectric cell is connected with the MCU input end through amplifying circuit, data acquisition circuit; MCU also with the two-way communication of MAX232 chip, the MAX232 chip is connected with computer by Serial Port Line.
Program design flow process of the present utility model, start back system initialization is waited for the computing machine response.Computer (host computer) is given the MCU(slave computer by Serial Port Line through the MAX232 chip) send data, slave computer receives the online success of expression behind the signal, and instrument carries out self check, and self check success back signal lamp be green, and if any unusually, signal lamp is a redness.Can close machine check this moment.After self check finished, instrument entered cleaning procedure, the detergent line system.Enter holding state after cleaning finishes together, wait for that host computer sends order.Instrument can once position according to the order that host computer sends, and cleans sampling, temperature control, parameter setting.Slave computer rotates by the control motor and realizes the location, realize cleaning and sampling by the control peristaltic pump, sample by photoelectric cell and amplifying circuit, and the data that collect are carried out analyzing and processing send to host computer by Serial Port Line then, host computer shows accordingly by the data that slave computer is sent back that finally we just can obtain the data value of test item.In addition, MCU records the current temperature of machine by temperature sensor, and before temperature did not arrive given temperature, MCU just controlled heater circuit machine is heated, and after temperature arrived assigned temperature, machine will stop heater circuit work.This flow process is circulation always after start, thereby reaches the function of control temperature.
The beneficial effect of the utility model patent is: the utility model is applied in the blood analyser, significantly reduces the error that human factor causes, has significantly improved the repeatability that detects, and the quality that detects for medical blood provides guarantee.
