Description

Technical Field

[0001] The utility model relates to the technical field of blood testing, in particular to an automatic blood shaker for testing. Background Art

[0002] At present, medical staff in the laboratory department usually shake the blood collection bottle, which is a long-term mechanical repetitive action with high labor intensity, low work efficiency and poor work quality. It often fails to meet the requirements of accurate testing, affects the test results, and increases the difficulty of the medical staff's work.

[0003] In order to solve the above problem, there is a solution of an automatic blood shaker for testing (Announcement No. CN215139189U), which drives the driving gear to rotate by starting the motor, so that the driven gear meshing with the driving gear can rotate, thereby driving the rotating disk above the rotating shaft to rotate, and then driving the blood storage tube to rotate, so that the blood in the blood storage tube can be shaken.

[0004] However, the above scheme shakes the blood by rotating the blood storage tube, and the blood storage tube will affect the dynamic balance of the rotating disk, so the rotating disk cannot rotate at a high speed, resulting in low blood mixing efficiency. When substances are added to the blood, substances with high density in the blood gather at the bottom of the test tube, while substances with low density gather at the top of the test tube, causing the blood to be stratified, and the blood storage tube needs to be continuously rotated to be mixed evenly. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic blood shaker for testing to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an automatic blood shaker for testing, comprising a base, a support plate and a protective cover are provided on the surface of the base, a motor is installed inside the protective cover, and an output end of the motor is connected to an inner pentagonal drive sleeve;

[0007] The movement of the sample tube is controlled by a motor, so that the sample tube rotates, and the blood inside the sample tube flows as the sample tube rotates, thereby achieving blood mixing;

[0008] A rectangular tube, both ends of the rectangular tube are provided with connection plates, the surfaces of the two connection plates are respectively provided with pentagonal columns and plug columns, the pentagonal columns are plugged with the inner pentagonal driving sleeve, the pentagonal columns and the inner pentagonal driving sleeve are used to control the rotation of the rectangular tube and the clamp, and the stability of power transmission is improved. A plurality of clamps are provided on the surface of the rectangular tube, and the clamps are used to open and clamp the sample tube;

[0009] A threaded tube, the threaded tube is threadedly connected to the support plate, a nitrogen spring is arranged inside the threaded tube, and the plug is inserted into the threaded tube and abuts against the nitrogen spring;

[0010] A circular ring, the circular ring is connected to the right connecting disk, and a plurality of arc grooves are provided on the surface of the circular ring, a roller is installed on the surface of the protective cover, and the roller is rollingly connected to the arc groove;

[0011] When the ring rotates, the roller rotates and cooperates with the arc groove to push the connecting disk to the left. When the roller is in the arc groove, the nitrogen spring will push the connecting disk to the right, causing the rectangular tube and the clamp to vibrate and accelerate the mixing of blood.

[0012] Furthermore, the clamp includes a support plate, a spring sheet is provided on the surface of the support plate, the spring sheet is used to clamp the container containing blood, a clamping pad is fixedly connected to the spring sheet, and a clamping groove is provided on the surface of the clamping pad, and a clamping force is applied to the sample tube by the spring sheet to prevent the sample tube from falling off during rotation. The clamping pad can achieve flexible clamping of the sample tube to ensure that the sample tube will not be damaged.

[0013] Furthermore, the surface of the pentagonal prism and the inner wall of the inner pentagonal driving sleeve are both provided with limiting grooves, and balls are installed between the pentagonal prism and the inner pentagonal driving sleeve, and the balls are rollingly connected to the limiting grooves. The balls reduce the sliding resistance of the pentagonal prism, which can ensure that the rectangular tube is not easily stuck due to vibration, making the vibration effect on the sample tube more stable.

[0014] Furthermore, a universal ball is installed at the right end of the plug column, and the universal ball is movably abutted against the nitrogen spring. The universal ball will not affect the rotation of the plug column and reduce the wear of the plug column and the nitrogen spring.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) When the motor controls the connection disk and the rectangular tube to rotate, the circular ring rotates synchronously. During the rotation of the circular ring, the roller continuously enters and exits the arc groove on the surface of the circular ring, and the nitrogen spring exerts force on the plug to the right, causing the roller to disengage from the arc groove, causing the rectangular tube to move to the left. The roller enters the arc groove, causing the rectangular tube to move to the right, thereby realizing the reciprocating movement of the rectangular tube. When the rectangular tube rotates rapidly, the frequency of the reciprocating movement can be increased, driving the sample tube to vibrate, so that the blood can be quickly shaken.

[0017] (2) The spring sheet applies elastic force to the clamp pads, and after the sample tube is inserted into the two clamp pads, the sample tube can be directly clamped, and the sample tube can be easily taken out and placed. The sample tube can be placed on the four sides of the rectangular tube, and a larger number of sample tubes can be shaken evenly, and a larger number of sample tubes can be shaken evenly at a time.

[0018] (3) The base is fixed by a suction cup, which can ensure that the base will not move when the rectangular tube vibrates, thereby preventing the mixer from moving on the desktop and improving the stability of use. BRIEF DESCRIPTION OF THE DRAWINGS
