Blood coagulation detection instrument

Abstract

The embodiment of the invention discloses a blood coagulation detection instrument. The instrument comprises a testing mechanism for detecting the elastic force of blood, a sample placing mechanism for placement of blood samples, and a transmission mechanism for operating the testing mechanism to approach or keep away from the sample placing mechanism. According to the blood coagulation detection instrument disclosed by the invention, by adopting magnetic attraction effects, a cup cover is pulled by the traction of a first magnetic force body and a second magnetic force body to stir a blood sample in a stirring cup, and microgenetic complex biological changes in a blood coagulation process are transformed into pulse signals by virtue of a coded disc and a signal transceiver and are acquired and processed to form thrombelastograms, so that a test process is simple to operate, the workload of operators can be reduced, and the cost can be saved.

Description

technical field [0001] The invention relates to the field of blood detection, in particular to a blood coagulation detection instrument. Background technique [0002] At present, hospitals usually use thromboelastography to monitor the patient's blood coagulation from the whole dynamic process, and use thromboelastometry to analyze the patient's blood and then output the thromboelastogram. [0003] The main working principle of the current thrombelastograph is to install a sensor on the upper end of the suspension wire to monitor the change of the torsion of the suspension wire, and hang a cup cover with a cylinder on the lower end, and the cylinder of the cup cover invades into the cup containing the blood sample. Among them, the cup body is installed on the constant temperature control board, and the constant temperature control board rotates back and forth at an angle of 4°45' to drive the cup body to rotate and affect the blood sample. As time increases, the resistance p...

AI Technical Summary

Problems solved by technology

[0007] 1. High operating requirements and high cost

The installation of the cup body and the cup cover must be handled carefully. Due to the difference in strength of each person, there are usually problems such as the cup body not being placed on the bottom of the reaction tank, resulting in inaccurate results, and the cup cover being not tightly assembled, resulting in falling during the test. This will cause problems. It leads to the re-collection of blood samples and the re-addition of reagents. Due to the high price of reagent samples, this will lead to high cost of manpower and material resources.

[0008] 2. There are many operation steps, and the workload of medical staff increases

This process greatly increases the workload of medical staff

[0009] 3. Requirements for the operating environment. Due to the limitation of the structure of the instrument itself, the test environment requires high levelness and verticality. It is easy to cause inaccurate results, errors or test failures due to vibration and insufficient level of instrument placement.
