Abstract

The invention discloses an automatic blood rheometer comprising an integration type temperature controlling module, a measuring module, a dynamic module, an infrared liquid level quantification module and a signal processing and controlling circuit. The integration type temperature controlling module comprises a temperature sensor and a heating panel. The measuring module comprises a U-shaped glass tube and a pressure sensor. The dynamic module comprises a direct-current peristaltic pump, a solenoid valve set and a silica gel pipeline. The heating panel, the temperature sensor and the U-shaped glass tube are arranged in a sealed heat-insulating box. The pressure sensor is connected to the U-shaped glass tube through the silica gel pipeline. Signals outputted by the pressure sensor are transmitted to the signal processing and controlling circuit, and is subject to a sampling treatment. Treatment data is delivered to a computer. With the blood rheometer provided by the invention, rapid measuring can be carried out upon whole blood apparent viscosity and a relation thereof with shear rate. The blood rheometer can also be used in the measurement of blood plasma absolute viscosity. With the blood rheometer, a plurality of samples can be automatically detected within one time. Therefore, operation processes of operators can be greatly simplified. The blood rheometer is advantaged in stable performance, high automation degree, and improved efficiency.

Description

technical field [0001] The invention relates to a blood testing instrument, in particular to an automatic blood rheometer. Background technique [0002] The detection of blood rheology index is highly valued by the clinical medical community. At present, there are two main types of blood rheology detection instruments: capillary viscometer and rotational viscometer. Capillary viscometer is a product of the late 1970s in our country. Most of the major hospitals in our country have used it. Because of its measurement limitations, it is only suitable for the measurement of plasma viscosity, and the operation is very cumbersome, with poor repeatability and accuracy. The pollution is serious and has been eliminated by the clinic year by year; the other type is the rotational viscometer. This method requires high processing accuracy, and the components are easy to fatigue, resulting in decreased instrument accuracy, poor repeatability, and low degree of automation. SUMMARY OF TH...
