Description

Technical Field

[0001] The utility model belongs to the technical field of blood testing, and in particular relates to a blood oscillation device for testing. Background Art

[0002] Blood testing (also known as blood tests or blood assays) is a common medical laboratory test designed to assess an individual's health status, diagnose disease, and monitor disease progression. This test provides detailed information about an individual's health status by analyzing various components and indicators in a blood sample. Blood testing is an important tool in clinical diagnosis, providing doctors with critical information needed for diagnosis and treatment planning. Shaking during blood testing helps to evenly mix the various components of the blood (such as blood cells, plasma, platelets, etc.). It ensures the consistency and uniformity of the sample, thereby helping laboratory equipment to accurately measure various blood indicators. Shaking prevents the blood from clotting or forming blood clots prematurely after collection. In some blood tests, especially when thromboelastography (TEG) or similar tests are required, it is critical to ensure that the blood sample remains in a flowing state in order to obtain accurate coagulation parameters.

[0003] Too violent agitation will introduce bubbles into the blood sample, which will affect the optical and electrochemical analysis of the blood and lead to errors in the results. Utility Model Content

[0004] In view of this, the utility model provides a blood shaking device for testing, aiming to solve the problem that excessively violent shaking may introduce bubbles into the blood sample, affect the optical and electrochemical analysis of the blood, and cause error in the results.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a blood oscillation device for testing, which comprises a blood collection tube, a vibration mechanism and a rotation mechanism; the vibration mechanism is arranged directly below the blood collection tube, the vibration mechanism abuts against the lower wall of the blood collection tube, and the vibration mechanism is used to vibrate the blood collection tube; the vibration mechanism comprises a first rotating shaft, a vibration paddle and a slot, the slots are arranged on both sides of the vibration paddle, the vibration paddle is a fan-shaped structure, the side of the vibration paddle has an arc-shaped depression, there are 4 vibration paddles, the vibration paddles are arranged in vertical and horizontal directions, a connecting plate is arranged in the center of the 4 vibration paddles, and the first rotating shaft is fixedly arranged at the center of the connecting plate; the rotation mechanism comprises a toggle shaft, matching teeth, a rotating plate and a second rotating shaft, and the rotation mechanism is used to drive the vibration mechanism to rotate.

[0007] The technical effects of a blood shaking device for testing provided by the utility model are as follows: by setting a vibration mechanism, various components in the blood (such as blood cells, plasma, platelets, etc.) can be evenly mixed together, which is conducive to ensuring the consistency and uniformity of the sample, thereby helping laboratory equipment to accurately measure various blood indicators; it can also prevent the blood from coagulating or forming thrombi prematurely after collection, ensuring that the blood sample remains in a flowing state to obtain accurate coagulation parameters.

[0008] By setting the matching teeth, the matching teeth are not embedded in the card slot for a period of time but rotate on their own, which produces the following technical effects: intermittently oscillating the blood to avoid bubbles in the blood sample that affect the optical and electrochemical analysis of the blood.

[0009] On the basis of the above technical solution, the blood oscillation device for testing of the utility model can also be improved as follows:

[0010] Among them, the side wall of the rotating plate is fitted with the side wall of the vibration paddle, the second rotating shaft is fixedly arranged at the center position of the rotating plate, the rotating plate is a crescent-shaped structure, the toggle shaft is fixedly connected to the side wall of the rotating plate, the mating tooth is fixedly arranged at the outer end of the toggle shaft, the second rotating shaft and the first rotating shaft are both fixedly connected to the output shaft of the motor; the mating tooth is embedded in the slot.

[0011] The motor is an AC motor.

[0012] Furthermore, the arc radius of the arc-shaped recess on the side of the vibration paddle is equal to the radius of the rotating plate.

[0013] Furthermore, the mating tooth is a cylindrical structure, and the length of the mating tooth is greater than the width of the opening of the slot.

[0014] Furthermore, the first rotation axis and the second rotation axis are on the same horizontal line.

[0015] Furthermore, the angle between the center line of the slots on both sides of the vibration paddle and the center line of the first rotation axis is equal to 90 degrees.

[0016] Furthermore, the center angle of the arc-shaped depression on the side of the vibration paddle is 80°.

[0017] Furthermore, the side walls of the slots on both sides of the vibration pick are tangent to the arc of the circular motion of the mating teeth.

[0018] Furthermore, an isolation layer is provided on the outer sides of both ends of the arc-shaped recess of the side wall of the vibration paddle.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting an isolation layer, the vibration paddle and the lower wall of the blood collection tube can be protected. Since the vibration paddle will frequently vibrate and contact the lower wall of the blood collection tube during operation, the isolation layer can reduce direct friction and wear, reduce the degree of wear, extend the service life of the vibration paddle and the blood collection tube, and improve the stability and reliability of the device. At the same time, the use of the isolation layer can partially absorb and reduce the spread of vibration and noise, and improve the working environment.

[0020] Furthermore, the isolation layer is made of rubber.

[0021] Compared with the prior art, the beneficial effect of the blood vibration device for testing provided by the utility model is that by setting a vibration mechanism, various components in the blood (such as blood cells, plasma, platelets, etc.) can be evenly mixed together, which is conducive to ensuring the consistency and uniformity of the sample, thereby helping laboratory equipment to accurately measure various blood indicators; it can also prevent the blood from coagulating or forming blood clots prematurely after collection, ensuring that the blood sample remains in a flowing state to obtain accurate coagulation parameters.

[0022] By setting the mating teeth, the mating teeth are not embedded in the card slot for a period of time but are rotating, and the technical effect produced is: intermittently oscillating the blood to avoid bubbles in the blood sample that affect the optical and electrochemical analysis of the blood. By setting an isolation layer, the vibration paddle and the lower wall of the blood collection tube can be protected. Since the vibration paddle will frequently vibrate and contact the lower wall of the blood collection tube during operation, the isolation layer can reduce direct friction and wear, reduce the degree of wear, extend the service life of the vibration paddle and the blood collection tube, and improve the stability and reliability of the device. At the same time, the use of the isolation layer can partially absorb and reduce the spread of vibration and noise, and improve the working environment. It can solve the problem that excessive vibration will introduce bubbles into the blood sample, affect the optical and electrochemical analysis of the blood, and cause errors in the results.

[0029] During use, fix the blood collection tube 1, then place the vibration mechanism 2 below the blood collection tube 1 so that the vibration paddle 22 abuts against the lower wall of the blood collection tube 1. The second rotating shaft 34 in the rotating mechanism 3 drives the rotating plate 33 to rotate. The pushing shaft 31 on the rotating plate 33 rotates, and the matching teeth 32 are engaged in the card slots 23. As the matching teeth 32 rotate, the matching teeth 32 push the vibration paddle 22 to drive the vibration paddle 22 to rotate. The sector structure and arc-shaped depression design of the vibration paddle 22 cause the blood in the blood collection tube 1 to be oscillated. Through vibration, the blood flows and mixes in the blood collection tube 1. The use of the isolation layer effectively reduces the friction and wear during the vibration process, protects the vibration paddle and the lower wall of the blood collection tube 1, and extends the service life of the device. It should be noted that the matching teeth 32 do not engage in the card slots 23 for a period of time but rotate on their own, and the technical effect produced is: intermittently oscillating the blood to avoid generating bubbles in the blood sample and affecting the optical and electrochemical analysis of the blood.

[0030] Among them, in the above technical scheme, the side wall of the rotating plate 33 is in contact with the side wall of the vibration paddle 22, the second rotating shaft 34 is fixedly arranged at the center position of the rotating plate 33, the rotating plate 33 is a crescent-shaped structure, the driving shaft 31 is fixedly connected to the side wall of the rotating plate 33, the mating tooth 32 is fixedly arranged at the outer end of the driving shaft 31, the second rotating shaft 34 and the first rotating shaft 21 are both fixedly connected to the output shaft of the motor; the mating tooth 32 is embedded in the slot 23.

[0031] Furthermore, in the above technical solution, the arc radius of the arc-shaped recess on the side of the vibration paddle 22 is equal to the radius of the rotating plate 33 .

[0032] Furthermore, in the above technical solution, the mating tooth 32 is a cylindrical structure, and the length of the mating tooth 32 is greater than the width of the opening of the slot 23 .

[0033] Furthermore, in the above technical solution, the first rotation axis 21 and the second rotation axis 34 are on the same horizontal line.

[0034] Furthermore, in the above technical solution, the angle between the center line of the slots 23 on both sides of the vibration paddle 22 and the center line of the first rotation axis 21 is equal to 90 degrees.

[0036] Furthermore, in the above technical solution, the side walls of the slots 23 on both sides of the vibration paddle 22 are circumscribed to the arc of the circular motion of the mating teeth 32 .

[0037] Furthermore, in the above technical solution, an isolation layer is provided on the outer sides of both ends of the arc-shaped recess on the side wall of the vibration paddle 22 .

[0038] Furthermore, in the above technical solution, the isolation layer is made of rubber.

[0039] Specifically, the principle of the utility model is: fix the blood collection tube 1, then place the vibration mechanism 2 under the blood collection tube 1, so that the vibration paddle 22 abuts against the lower wall of the blood collection tube 1, the second rotating shaft 34 in the rotating mechanism 3 drives the rotating plate 33 to rotate, and the toggle shaft 31 on the rotating plate 33 rotates, and the matching tooth 32 is embedded in the card slot 23.

Through vibration, the blood flows and mixes in the blood collection tube 1. The use of the isolation layer effectively reduces the friction and wear during the vibration process, protects the vibration paddle and the lower wall of the blood collection tube 1, and prolongs the service life of the device.
