Abstract

The invention discloses a blood oscillating and mixing device with adjustable vibration frequency for blood detection. The bottom of the blood mixing container of the invention uses a high-frequency vibration mechanism to oscillate. Since it uses a piezoelectric ceramic stack for oscillation control, the oscillation The oscillation frequency of the method is high and the amplitude is small, which can prevent the blood from swaying too much in the test tube wall due to excessive oscillation, and reduce the loss of blood. At the same time, the rotary driver of the present invention can drive the blood mixing container to swing through the connecting rod assembly , and can move linearly along the direction of the line between the blood mixing container and the rotary driver, so that when the blood is oscillated, the blood in the vertically arranged blood test tubes can vibrate more efficiently in the horizontal direction Sequence, will not produce excessive or excessive oscillation in the vertical direction, and the oscillation is easy to control, stable and orderly.

Description

technical field

[0001] The invention relates to a blood vibration mixing device for blood detection with adjustable vibration frequency, which belongs to the technical field of blood vibration. Background technique

[0002] In blood routine testing, for the collected blood, in order to reduce the rapid coagulation of blood in the collection tube, an oscillating mixer is often used to oscillate the capped collection tube. The current oscillating mixing device generally places the collection tube in a vibrating In the groove between the rollers on the middle side of the mixer, the rollers will also rotate during the vibration of the oscillating mixer, driving the collection tube to rotate up and down. However, because the collection tube rotates up and down in this way, during the rotation, It is easy to make the blood flow on the tube wall, and the blood will stain the entire tube wall, resulting in a decrease in the amount of blood that can be taken out in the tube, or it wi...
