Magnetic suspension thrombelastogram instrument

Abstract

The invention discloses a magnetic suspension thrombelastogram instrument and belongs to the technical field of medical apparatus and instruments. The instrument comprises a shell, a rack, a plurality of detection devices and transmission devices corresponding to the detection devices one by one, and also comprises an axial magnetic suspension mechanism, a radial magnetic suspension mechanism and a magnetic flux detection device which are sequentially arranged at the periphery of a probe rod in a sleeving manner. The magnetic suspension thrombelastogram instrument disclosed by the invention adopts a magnetic suspension structure, and the problems in the traditional equipment that an overhung wire is difficult to machine, the quality is difficult to guarantee, the manufacturing cost is relatively high and the like are solved; and moreover, a torsion state of the overhung wire is simulated by utilizing a pair of radial magnets, the torsion rigidity of the overhung wire is changed by accurately adjusting the distance of the radial magnets, and the problem that the parameters of the overhung wire cannot be adjusted after the overhung wire is completely machined is solved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a magnetic levitation thromboelastography instrument. Background technique [0002] The traditional thrombelastograph basically uses the suspension wire to measure the change of the shear stress during the dynamic coagulation process, but there are problems of low measurement accuracy and large multi-channel error. , assembly and other requirements are high, resulting in high manufacturing costs, high maintenance costs, and the parameters cannot be changed after the suspension wire processing is completed. [0003] Magnetic levitation technology uses the characteristics of magnets that "same sex repels each other and opposite sex attracts each other", so that the magnet has the ability to balance the gravity of the load and produce the effect of "magnetic levitation". Now it is widely used in trains, airplanes, spacecraft and so on. However, the existing magnetic le...
