Blood blending device for hemorheology instrument

Abstract

The invention discloses a blood blending device for a hemorheology instrument. The blood blending device comprises a rack, wherein the rack is provided with a hoisting mechanism; the hoisting mechanism comprises a hoisting part capable of moving up and down; the hoisting part is provided with a first stepping motor for uniformly shaking; an output end of the first stepping motor is connected ontoa blood sampling pipe clamping device; the blood sampling pipe clamping device comprises a second stepping motor, and a first clamping part and a second clamping part which are used for clamping a blood sampling pipe; tooth surfaces of a first rack and a second rack are opposite and are engaged and matched with a gear; the gear is arranged at an output end of the second stepping motor. The blood blending device for the hemorheology instrument, disclosed by the invention, is novel in concept, reasonable in design and convenient to operate; the stepping motors are used for realizing overturningand uniform shaking; the blood blending device has good controllability and is easy to manufacture; meanwhile, the blood sampling pipe is clamped by adopting the stepping motors and the loading capability is strong; the plurality of blood sampling pipes can be clamped; meanwhile, compared with the prior art, the blood blending device has good stability when being used and a condition that equipment is stopped due to heating is avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a blood mixing device used for a blood rheometer. Background technique [0002] Hemorheology is a blood clinical testing instrument developed on the basis of the theory of hemorheology. It is a special testing instrument for early diagnosis of diseases by testing the viscosity of human blood. During the use of the hemorheometer, it is necessary to grab the blood collection tube and shake it to provide a basis for subsequent detection. The shaking angle is generally limited. In the prior art, a sensor is generally used to control the angle, and then control the amplitude of the shaking action. The overall structure is complicated and the control is troublesome. In addition, the existing blood collection tube clamping device uses a relay to realize the clamping action, and often only clamps one blood collection tube, and the relay will generate heat during use and stop w...
