Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a blood testing device and a testing method thereof. Background Art

[0002] During the annual physical examination, testing the plasma components in the blood can evaluate indicators such as liver function, kidney function, blood sugar, lipids, and understand the overall health status. When the patient undergoing the physical examination has unexplained symptoms (such as fatigue, pain, fever, etc.), the doctor will recommend a plasma component test to help determine the cause, so the patient needs to have blood drawn. It mainly refers to the process in which medical staff extract venous blood samples from the patient's body using a needle or other equipment, and store the extracted blood samples in a blood collection tube. The extracted blood samples also need to be marked to ensure the accuracy of the sample information, and then processed and transported, and the samples are placed in a biochemical analyzer for biochemical testing.

[0003] Since blood is prone to coagulation in vitro, especially when the sample needs to be subsequently tested for plasma components, in order to ensure that liquid plasma is obtained, anticoagulants must be added to prevent the coagulation process from occurring.

[0004] In the prior art, medical staff usually choose purple or blue blood collection tubes containing anticoagulants, store the drawn blood samples in the blood collection tubes, and then shake the blood collection tubes to mix them. However, the operating skills of different medical staff may be different. If the anticoagulant is not fully mixed, it may cause local uneven concentration, thereby reducing the accuracy of detecting plasma components. Medical staff are also required to shake the blood within a few minutes after blood drawing to ensure that the anticoagulant can take effect in time.

When the sealing disk 4 rotates clockwise, the knocking end of the knocking mechanism faces the top of the shaking and mixing mechanism, and the taking hole 18 and the placing hole 17 are staggered. A preservation box 5 is fixedly connected to the top of the workbench 1 and is arranged on one side of the detection disk 2, wherein a storage box 7 is arranged in the preservation box 5 through a reciprocating lifting mechanism, and when the storage box 7 moves up and down in the preservation box 5, the knocking end of the knocking mechanism extends outward or retracts inward.

[0024] Rotate the sealing disk 4 on the top of the test disk 2 counterclockwise so that the taking hole 18 on the sealing disk 4 coincides with the placement hole 17 on the test disk 2, and then place the blood collection tube on the shaking and mixing mechanism. At this time, the shaking and mixing mechanism will continue to gently shake the anticoagulant and blood inside the blood collection tube, thereby avoiding the phenomenon of blood coagulation due to uneven mixing, and can enable medical staff to quickly and gently shake the blood collection tube after blood collection to evenly mix and prevent the anticoagulant from being fully mixed, thereby ensuring uniform local concentration, thereby improving the accuracy of detecting plasma components, and can also quickly shake the blood and anticoagulant in the blood collection tube within a few minutes after blood drawing to ensure that the anticoagulant can take effect in time, which will not only reduce the waiting time for subsequent patients, but also reduce the workload of medical staff.

[0025] A limiting groove 19 is provided on the side wall of the detection disk 2, and a connecting plate 20 is fixedly connected to the sealing disk 4. The connecting plate 20 is slidably connected to the limiting groove 19, and the rotation range of the sealing disk 4 can be limited by the limiting groove 19.

[0026] When shaking the blood collection tube, the shaking and mixing mechanism needs to rotate the sealing disk 4 clockwise so that the taking hole 18 on the sealing disk 4 and the placement hole 17 on the detection disk 2 are in a misaligned state, and the knocking end of the knocking mechanism will be moved to the top of the blood collection tube to knock the top of the blood collection tube back and forth, thereby cooperating with the shaking and mixing mechanism to help the anticoagulant in the blood collection tube to be dispersed in the blood sample faster and more evenly, ensuring that the anticoagulant effect is fully exerted.

[0027] After the blood collection tube is shaken and mixed, which is usually done for ten seconds, the sealing disk 4 can be rotated counterclockwise to make the taking hole 18 coincide with the placement hole 17 on the detection disk 2, and then the blood collection tube can be placed in the storage box 7 in the preservation box 5, and the reciprocating lifting mechanism will drive the storage box 7 to move up and down in the preservation box 5, and when the storage box 7 is lifted and moved back and forth, the knocking end of the knocking mechanism will move back and forth synchronously to prevent the knocking end from repeatedly knocking on the top of the blood collection tube, so that the blood collection tube can be knocked one or two times during the shaking process, thereby improving the practicality of the device.

[0030] In order to enable the three groups of push rods 24 to push the blood collection tubes in a separate cycle, a rotating shaft 13 is rotatably connected to the detection disk 2, a cam 22 is fixedly connected to the top of the rotating shaft 13, a booster cylinder 26 is fixedly connected to the support bracket 21, a booster rod 27 is slidably connected to the booster cylinder 26, a piston is provided at one end of the booster rod 27, and the piston fits against the inner wall of the booster cylinder 26, a mounting seat 28 is fixedly connected to the other end of the booster rod 27, a roller 29 is rotatably connected to the mounting seat 28, the roller 29 fits against the outer wall of the cam 22, a piston is provided at the end of the push rod 24 away from the push plate 25, and the piston fits against the inner wall of the push cylinder 23, and the booster cylinder 26 is connected to the push cylinder 23 through a pipeline.

During this process, the main pulley driven by the belt will drive the auxiliary pulley, and the auxiliary pulley will drive the screw 11 to rotate in the preservation box 5, so that the movable block 12 can move up and down in the preservation box 5, thereby driving the blood collection tubes that have been shaken and mixed or are about to be shaken and mixed to move up and down, further promoting the uniform distribution of blood and anticoagulants, ensuring the consistency of the samples, and making the subsequent analysis results more reliable.

[0036] A slide groove 8 is provided on the inner wall of the storage box 7, and a placement plate 9 is slidably connected to the slide groove 8.
