Embodiment 1

[0031] Embodiment one: if figure 1 As shown, in the device for blood rheology detection, the coaxial shaft on the main shaft of the centrifugal motor 4 is fixed with a stepping drive driven gear 7, and the output end of the main shaft of the stepping motor 10 is provided with a stepping driving driving gear. 8. The stepping driving driving gear 8 and the stepping driving driven gear 7 constitute the clutch transmission device. The stepping motor 10 and the stepping drive driving gear 8 are relatively fixed in position. The stepping motor 10 is installed on the moving part of a translation device 9 , and the fixed part of the translation device 9 is relatively fixed with the main support 12 . Also shown in the figure is a speed measuring device 5 for measuring the rotational speed of the main shaft of the centrifugal motor. A magnet 6 is bonded to the main shaft of the centrifugal motor, and the magnet 6 faces the speed measuring device. The two cooperate to detect the speed of...

Embodiment 2

[0034] Embodiment two: if figure 2 As shown, in the device for blood rheology detection, the output end of the main shaft of the stepping motor 10 is also provided with a stepping drive driving gear 8, which cooperates with the stepping driving driving gear 8 to form a stepping drive slave of a clutch transmission. The gear 7 is arranged on a fixed shaft 14, and may be mounted on the fixed shaft through a bearing. The fixed shaft 14 is relatively fixed to the main bracket 12 ; the main shaft 1 of the centrifugal motor is arranged coaxially with the fixed shaft 14 and connected by a coupling 13 . The position of the stepper motor 10 and the stepping driving driving gear 8 is relatively fixed, and the stepper motor 10 is installed on the moving part of a translation device 9 , and the fixed part of the translation device 9 is relatively fixed with the main support 12 .

[0035]During high-speed centrifugation, the main shaft 1 of the centrifugal motor drives the coupling 13 an...

Embodiment 3

[0036] Embodiment three: as image 3 As shown, in this embodiment, the output end of the stepper motor 10 main shaft is provided with a stepping drive active synchronous pulley 28, and the synchronous belt 20 bypasses the stepping driving active synchronous pulley 28 and bypasses the first guide wheel 21, the second Two guide wheels 22, the first tensioner 18, the second tensioner 19. The step driving driven synchronous pulley 27 and the step driving driving synchronous pulley 28 and the synchronous belt 20 constituting the clutch type transmission device are arranged on the main shaft 1 of the centrifugal motor. The position of the stepper motor 10 and the stepping drive active synchronous pulley 28 is relatively fixed and relatively fixed with the main support 12; 12 is relatively fixed. When the translation device realizes that the synchronous belt 20 moves to the direction of the step-driven driven synchronous pulley 27, the distance between the two tensioners decreases,...

Abstract

The invention discloses a hemorheology detecting device. The hemorheology detecting device comprises a main support, a centrifugal rotating disc and a centrifugal motor. The centrifugal rotating disc is installed on a main shaft of the centrifugal motor. The hemorheology detecting device further comprises a stepping motor. A main shaft of the stepping motor drives the centrifugal rotating disc to rotate by a certain angle after centrifuging is finished. The hemorheology detecting device is characterized in that after centrifuging is finished, the main shaft of the stepping motor drives the main shaft of the centrifugal motor to drive the centrifugal rotating disc to rotate by the certain angle. A mechanism for driving the sample disc to be positioned is simple in structure, and the arrangement of a sampling device can not be influenced.

Description

technical field [0001] The invention relates to a device for blood rheology detection. Background technique [0002] For clinical examination of blood rheology items, hemorheology dynamic analyzers are usually used to measure the viscosity of whole blood and plasma, but manual measurement of erythrocyte sedimentation rate and hematocrit is also required, and the results of complete hemorheology dynamic analysis must have full The viscosity value of blood and plasma, the measured value of erythrocyte sedimentation rate and pressure volume can have diagnostic significance. After the measurement of whole blood viscosity, the whole blood test tube should be placed in the centrifugal motor for high-speed centrifugation, and then the blood in the sample test tube should be sucked. The upper layer of plasma is used for plasma viscosity detection and pressure volume measurement. After the whole blood measurement is completed, it is also necessary to draw the whole blood, fill it int...
