Embodiment 1

[0039] Such as figure 1 with figure 2 As shown, the non-contact inductive angle measuring device for thromboelastography of the present invention includes a rotating part 10 and a stationary part 20, the stationary part 20 is provided with an inductive detection unit 30, and the rotating part 10 corresponds to The area of ​​the inductive detection unit 30 is provided with an induction area 12, and the rotating part 10 and the stationary part 20 are connected by a single-point contact, and there is a gap between the rotating part 10 and the stationary part 20 to ensure that the rotating part 10 and the stationary There is no friction between the parts 20.

[0040] The single-point connection between the rotating part 10 and the stationary part 20 is realized through the shaft tip 40 and the jewel bearing 50 to ensure the minimum frictional force between the rotating part 10 and the stationary part 20 .

[0041] The gap maintained between the rotating part 10 and the stationa...

Abstract

The invention aims to disclose a non-contact type inductive angle measuring device and a non-contact type inductive angle measuring method thereof for a thromblastography TEG. The non-contact type inductive angle measuring device comprises a rotating portion and a stationary portion, wherein a detection unit is arranged on the stationary portion, and the rotating portion is in one-point connectionwith the stationary portion by means of a shaft tip and a jewel bearing. Compared with the prior art, the rotation generated by a minute force can be detected since the friction between the rotatingportion and the stationary portion is negligible; the resolution of a sensor of the detection unit can reach 17 digits, so the angular resolution can reach 0.0027 degrees, and minor angle changes canbe detected; at the same time, the installation has no complicated structure to be adjusted, the device just needs to ensure to be horizontal so that a gap is kept between the rotating portion and thestationary portion, the structure is simple and very practical, and the purpose of the invention is achieved.

Description

technical field [0001] The invention relates to a non-contact inductive angle measuring device and a measuring method thereof, in particular to a non-contact inductive angle measuring device and a measuring method for a thromboelastography instrument suitable for thromboelastogram detection in blood analysis. Background technique [0002] Thromboelastography (TEG) is an analyzer that monitors the coagulation process from the entire dynamic process of platelet aggregation, coagulation and fibrinolysis. [0003] Monitoring the physical properties of blood clots is based on the following principle: a stationary cylindrical cup containing blood is rotated at a small angle at low speed, and the movement of the blood sample is monitored by a measuring rod immersed in the blood sample. After the fibrin-platelet complex glues the cylindrical cup and the measuring rod together, the rotational force generated by the rotation of the cylindrical cup can be transmitted to the measuring r...
