Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary processor for medical test samples. Background Art

[0002] In the blood testing department of a hospital, medical staff need to store and test the blood collected from the patient. The instruments used include blood drawers, storage tubes, etc. When the blood needs to be stored for a long time, it needs to be stored in anticoagulant tubes to prevent the blood from clotting quickly.

[0003] At present, during the blood collection process, there is usually an anticoagulant in the test tube. After the test tube blood collection is completed, the test tube needs to be shaken so that the anticoagulant and the blood are fully mixed, thereby preventing the blood from coagulating. The blood sample test tube is manually shaken by medical personnel. Since a large amount of anticoagulant inside the test tube is attached to the inner wall of the test tube, and the blood has a viscous property, it takes a long time to fully mix the anticoagulant and the blood through natural shaking. In addition, manually shaking the blood sample by medical personnel is not only time-consuming and laborious, but also has a low mixing efficiency. In addition, when medical staff manually shake the sampling test tube, they can often only shake one sampling test tube at a time, which cannot meet the shaking needs of large quantities of collected samples; therefore, the above-mentioned deficiencies exist and cannot meet the use needs of medical personnel. Therefore, further improvements are necessary.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a medical test sample auxiliary processor is provided, in order to achieve a more practical purpose. Summary of the invention

[0061] The specific usage and function of this embodiment are as follows:

[0062] Working principle: When in use, the sample collection test tube is placed in the test tube holder 3, and the bottom of the test tube is in contact with the support base 5. By pressing the test tube, the support base 5 is moved downward, and the extrusion plate 11 is pushed to squeeze the transmission airbag 1 14, so that the gas in the transmission airbag 1 14 is transmitted to the transmission airbag 2 16 along the ventilation tube 15, and then the expanded transmission airbag 2 16 pushes the movable plate 17 to move, and at the same time, the unloading component 18 is used to push the positioning plate 8 to move toward the test tube, and the positioning mechanism 9 is used to contact the test tube. At this time, the positioning tooth 92 is consistent with the outer surface of the test tube under the action of the ball pin 921, and the fixed suction cup 93 is used to fit and contact with the test tube. The squeezing force of the positioning plate 8 causes the fixed suction cup 93 to fit firmly on the outer surface of the test tube, and all the air inside the fixed suction cup 93 is discharged outward, so that the fixed suction cup 93 forms a negative pressure state, which can effectively ensure the adsorption force of the fixed suction cup 93 on the test tube, and effectively enhance the stability of the test tube when it is shaken. By setting the positioning teeth 92 to be rotatable, the movement characteristics of the positioning teeth 92 that can rotate along the obstacle points encountered when the positioning teeth 92 are stressed can be used to make the positioning teeth 92 adaptively rotate to the position with the largest contact area with the outer surface of the test tube and the most stable stress, so that the positioning teeth 92 can always automatically rotate to the position that fits the test tube best, thereby forming the most stable positioning structure, further improving the fixing effect of the test tube;

[0063] In addition, in the process of the movable plate 17 pushing the positioning plate 8 and the positioning mechanism 9 to fix and clamp the test tube, the reaction force of the test tube on the positioning plate 8 and the positioning mechanism 9 pushes the unloading shell 182 to move toward the unloading seat 181, and the connecting rod 192 is used to push the unloading plate 191 to move while the unloading shell 182 moves, and the unloading spring 193 is squeezed by the unloading plate 191. In the process of the unloading plate 191 squeezing the unloading spring 193, the elastic member 194 on the outer periphery of the unloading plate 191 is continuously combined with the buffer groove 1812. By utilizing the resistance generated by the contact between the elastic member 194 and the buffer groove 1812 and the elastic force of the unloading spring 193, on the one hand, the positioning plate 8 and the positioning mechanism 9 can unload the excessive clamping force of the test tube, and on the other hand, it can also prevent the excessive unloading from affecting the clamping and fixing effect of the positioning plate 8 and the positioning mechanism 9 on the test tube.

[0064] After the test tube is firmly fixed, the electric telescopic device 25 is started, and the telescopic rod of the electric telescopic device 25 is used to push the movable frame 20 and the shaking ball 23 to move upward. As the shaking ball 23 continues to move upward, the shaking ball 23 is prompted to just contact with the movable groove 241 at the bottom of the shaking block 24 and be located therein. Since the shaking ball 23 is set in a high and low state, the shaking part 2 and the shaking block 24 are in an inclined state, and the servo motor 21 is driven to drive the rotating shaft 211 and the movable frame 20 and the shaking ball 23 to move upward. The rod 22 rotates, causing the shaking ball 23 to continuously rotate in the movable groove 241 of the shaking block 24, so that the shaking part 2 drives the test tube to continuously shake, thereby realizing centrifugal movement of the blood sample, and further ensuring that the blood sample is evenly shaken, so that the blood sample and the anticoagulant in the test tube are fully mixed, thereby achieving the purpose of improving the mixing efficiency, and at the same time, a large number of sample collection test tubes can be synchronously shaken, which greatly facilitates the work of medical staff and can effectively improve work efficiency, and therefore has good practicality.
