Vibration frequency adjustable blood vibration mixer for blood detection

Abstract

The invention discloses a vibration frequency adjustable blood vibration mixer for blood detection. A high-frequency vibration mechanism is used in the bottom of a blood mixing container for vibration. A piezoelectric ceramic pile is used for vibration control, so that vibration is high in frequency and low in amplitude, the phenomenon that too much blood is shaken within the wall of a test tube due to too large vibration can be prevented, and blood loss is reduced; a rotation driver drives the blood mixing container to swing as well as make linear motion in the direction of a connecting linebetween the container and the driver by means of a connecting rod assembly, so that when the blood is vibrated, blood in the blood test tube arranged vertically can be horizontally vibrated in a moreordered way and prevented from too large vertical vibration; and vibration is easy to control, stable and ordered.

Description

Technical field [0001] The invention relates to a blood oscillation mixing device capable of adjusting the oscillation frequency for blood detection, and belongs to the technical field of blood oscillation. Background technique [0002] During the blood test, for the collected blood, in order to reduce the rapid coagulation of the blood in the collection tube, the oscillating mixer is often used to oscillate the collection tube covered with the tube cap. The current oscillating mixing device generally places the collection tube in the oscillation In the groove between the rollers on the middle side of the mixer, the rollers will also rotate during the vibration process of the oscillating mixer, driving the collection tube to rotate up and down. However, in this way, because the collection tube rotates up and down, during the rotation, It is easy to cause blood to flow on the tube wall. In the slightest, the blood will cover the entire tube wall, resulting in a decrease in the amo...

Problems solved by technology

[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 of the tube, or it will cause the blood to flow out of the collection tube, and even pollute the entire device
