Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0019] Such as figure 1 and figure 2 The shown calibrator for calibrating the detection channel of a thromboelastography instrument includes a measuring outer cylinder 1, the measuring outer cylinder 1 is cylindrical, the lower space 1a inside the measuring outer cylinder 1 is columnar, and the columnar lower space 1a is A stepped shape with a thin top and a thick bottom. The lower space 1a is on the same center line as the measuring outer cylinder 1 . The upper part of the measurement outer cylinder 1 is provided with a suspension 2, the suspension 2 is in the shape of a "T" with a thick top and a thin bottom, and the lower end is connected to the measurement outer cylinder 1 through a tight fit. A positioning rod 3 is fixed inside the measuring outer cylinder 1. The positioning rod 3 is in the shape of a "T" with a thick top and a thin bottom, and the u...

Abstract

The invention discloses a calibration instrument for calibrating a detection channel of a thromboelastography. The calibration instrument comprises a measurement outer barrel, wherein a suspension part is arranged at the upper part of the measurement outer barrel; a positioning rod is fixedly arranged in the measurement outer barrel; the positioning rod downwards extends out of the measurement outer barrel and penetrates through the center of a testing head; the testing head is suspended on the positioning rod through a spring; a rubber ring is arranged at the periphery of the testing head. The calibration instrument disclosed by the invention has the advantages of novel conception, reasonable design and convenience for operation; a torque value of a plurality of detection channel torsionwires in the multi-channel thromboelastography can be initially calibrated so that the detection precision of a whole body is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a calibrator for calibrating the detection channel of a thromboelastography instrument. Background technique [0002] Thromboelastography is a medical instrument that monitors and analyzes the coagulation process, and the detection channel of thromboelastography is its core detection component. Existing instruments are often single-channel detection, and do not involve multiple channels. In the detection, the detection is realized by hanging the measuring rod at the lower end of the twisted wire. Therefore, it is necessary to adjust to a unified initial benchmark during multi-channel detection to improve the overall detection accuracy. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a calibrator for calibrating the detection channel of a thromboelasto...
