Rotary sample addition type fully-automatic blood coagulation tester

Abstract

The invention discloses a rotary sample addition type fully-automatic blood coagulation tester. The tester which comprises a test system, a rotary sample addition system, an inclined reagent refrigeration system, a cleaning system and a cabinet is characterized in that the test system assembles four test channels which can simultaneously work; the rotary sample addition system comprises a rotary sample addition arm module, a sample addition probe module with constant temperature heating and liquid level probing functions, and a lead screw linear guide rail sample introduction control system; the inclined reagent refrigeration system which adopts an inclined mode to install a reagent bottle saves the reagent and avoids waste; and the cleaning system comprises an overflow type cleaning module and a double-channel peristaltic liquid charging and discharging system. The tester has the advantages of accurate test, accurate sample addition, reagent saving, long reagent preservation time, constant heating of the test system, high detection efficiency, simple operation, good cleaning effect, safe and efficient liquid discharge, and small noise.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rotary plus pattern automatic coagulation tester. Background technique [0002] Coagulation tester is an experimental tool used by hospitals to detect the strength of coagulation function of patients. There are four test items in one test process. At present, in the field of coagulation testing instruments, there are automatic coagulation testing instruments and semi-automatic coagulation testing instruments. The implementation method of automatic coagulation testing instruments is to use fixed partitions, and then inject blood samples and test agents. Due to the large number of partitions, In order to complete the entire automatic detection process, multiple XYZ motion systems are frequently crossed and run in each separate fixed interval, which also makes the test speed of the whole instrument slow, and the whole device is bulky and cumbersome, the test accuracy is not high...

At present, in the field of coagulation testing instruments, there are automatic coagulation testing instruments and semi-automatic coagulation testing instruments. The implementation method of automatic coagulation testing instruments is to use fixed partitions, and then inject blood samples and test agents. Due to the large number of partitions, In order to complete the entire automatic detection process, multiple XYZ motion systems are frequently crossed and run in each separate fixed interval, which also makes the test speed of the whole instrument slow, and the whole device is bulky and cumbersome, the test accuracy is not high, and it is not easy to control. High rate, difficult maintenance and high cost; semi-automatic coagulation tester requires a large labor cost, and cannot meet the requirements of large amount of test samples and short test time, automatic coagulation tester is suitable for testing a large number of samples, semi-automatic coagulation tester Although the tester is suitable for testing a small amount of samples, it consumes more manpower and time
