Hemodynamic analysis device

Abstract

The invention discloses a hemodynamic analysis device. The device comprises a detection mechanism, a sensing mechanism, a detecting cup and an oscillation mechanism, wherein the detection mechanism comprises a circuit board and a displacement actuator for regulating the circuit board to move up and down, and a connecting slot is formed in the circuit board; the sensing mechanism comprises a sensing chip which is detachably plugged in the connecting slot, and a probe is fixedly connected to the sensing chip; the detecting cup is arranged under the probe; and the oscillation mechanism is used for driving the detecting cup to oscillate regularly. According to the device, a blood sample in the detecting cup is regularly oscillated by virtue of the oscillation mechanism, the probe of the sensing mechanism is subjected to perform micro-displacement actuation by virtue of the driving capacitor of the sensing chip to simulate the physiological process of blood coagulation in a body, so that the detection analysis result is accurate and reliable; and the traditional electromagnetic measurement method is replaced by detection of the sensing mechanism, so that influence of vibration and friction on the analysis device is reduced, the measurement accuracy and sensitivity can be remarkably improved, and the biaxial dimensional dynamic data can be detected and acquired simultaneously.

Description

technical field [0001] The invention relates to the technical field of clinical coagulation analysis, in particular to a hemodynamic analysis device. Background technique [0002] Blood coagulation is blood coagulation, which refers to the process of blood changing from a flowing liquid state to an immobile gel state. It is an important part of physiological hemostasis. The essence of blood coagulation is that soluble fibrinogen in plasma changes into insoluble fiber protein process. Thromboelastometry is used in clinical testing and is one of the important tools for monitoring blood coagulation characteristics. The existing hemodynamic analysis device adopts the measurement method of freely suspended probe. The cup head of the measuring cup is fixed on the probe. It is not easy to keep the head upright when the head is put into the cup body, and the suspended probe is easily disturbed by external vibration and impact, and the dimension of the measurement parameters is limi...

Thromboelastometry is used in clinical testing and is one of the important tools for monitoring coagulation characteristics. The existing hemodynamic analysis device adopts the measurement method of freely suspended probe. The cup head of the measuring cup is fixed on the probe. It is not easy to keep the head upright when the head is put into the cup body, and the suspended probe is easily disturbed by external vibration and impact, and the dimension of the measurement parameters is limited to one axis; in addition, the measurement accuracy of the electromagnetic measurement method of the traditional analysis device is low , poor stability, low sensitivity, and a single measurement dimension, which can no longer meet the needs of current clinical coagulation detection and analysis
