Abstract

The invention provides a vibrational excitation device and belongs to the technical field of medical instruments. The vibrational excitation device comprises a vibrating source, a sensor and a controller, wherein the vibrating source is electrically connected with the controller; the vibrating source comprises a stator and a mover; the mover reciprocates relative to the stator under the action ofan alternating magnetic field or an external electric field; the mover is used for being externally connected with a coagulometer so as to drive the coagulometer to move; the controller controls the vibration amplitude and the accelerated speed of the reciprocation, relative to the stator, of the mover by adjusting the exerted alternating magnetic field and frequency or the external electric fieldstrength and frequency; and the sensor is disposed on the mover and used for collecting the moving vibration amplitude and accelerated speed of the mover. By means of the vibrational excitation device, the vibration amplitude and the accelerated speed of the coagulometer during vibration can be controlled to keep constant.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a vibration excitation device. Background technique

[0002] The coagulation analyzer is an instrument used clinically to analyze the coagulation and anticoagulation, fibrinolysis and antifibrinolysis functions of the patient's blood. Among them, the coagulation method can be used to determine the coagulation property or fibrinolytic property of the blood sample. Coagulation method (also known as biological method) coagulation method is to detect the changes of a series of physical quantities (light, electricity, mechanical movement, etc.) As a result, it can also be called a biophysical method.

[0003] The coagulation method is used to detect the coagulation characteristics of blood samples. During the coagulation detection process, a vibration source is provided to the coagulation analyzer to make it vibrate, and the coagulation performance is judged by detecting the...
