Description

Technical Field

[0001] The present invention belongs to the technical field related to reagent mixing, and more specifically, particularly relates to a reagent mixing processor for medical immunoassay. Background Art

[0002] Reagent mixing is a step often used in laboratory operations. The uniformity of reagent mixing affects the rate of biochemical reactions, the reliability and accuracy of experimental results. In the prior art, when mixing a small amount of reagents, the reagents are often placed in test tubes, and then the experimenter holds the test tubes to mix manually. This method is time-consuming and labor-intensive, and the mixing effect is not uniform. However, the reagent mixing processors in the prior art have the following defects:

[0003] There is a Chinese patent with application number CN202221090361.6, which discloses a reagent mixing device, including a base, a storage disk, and a rotating motor.

[0004] In the prior art, in order to improve the mixing effect of the upper and lower layered reagents, the reagent mixing processor usually arranges the test tubes on a disc at an angle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a reagent mixing processor for medical immunoassay. Through the arrangement of a first hydraulic chamber, a first piston plate, a second hydraulic chamber, a second piston plate, and an elastic rod, the first piston plate of the electric telescopic rod extending belt moves upward, and the first piston plate moves upward to squeeze the solution in the first hydraulic chamber into four second hydraulic chambers. The solution in the second hydraulic chamber pushes the two second piston plates away from each other, and the two second piston plates move away from each other, driving the two elastic rods away from each other, thereby pushing two relatively test tubes to rotate around two pairs of rotating shafts respectively, so that the multiple test tubes are arranged in an inclined manner, which is beneficial to quickly mixing the reagents in the upper and lower layers in the test tubes. By arranging the V-shaped elastic plate, the arc plate and the arc-shaped elastic member, the test tube rotates to push the arc plate to move, and the arc plate moves to squeeze the V-shaped elastic plate, and the V-shaped elastic plate squeezes to generate elastic force, and the elastic force generated by the V-shaped elastic plate acts on the arc plate, so as to continuously strengthen the friction between the inner side of the arc plate and the outer side of the test tube according to the degree of inclination of the test tube, and the movement of the second piston plate drives the elastic rod to move to cooperate with the test tube to be resisted by the arc plate and the V-shaped elastic plate, so as to clamp and fix the upper part of the test tube; and the arc-shaped elastic member is squeezed by the rotation of the test tube to generate elastic force, thereby squeezing and limiting the upper and lower parts of the test tube, which can adjust the inclination angle of the test tube and help prevent the test tube from falling out of the placement groove.

[0020] The reagent mixing processor for medical immunoassay of the present invention, through the revolution of several test tubes and the tilted arrangement of the test tubes, the centrifugal force generated by the rotation of the disk and the tilted arrangement of the test tubes, makes the reagent move up and down along the inner wall of the test tube, so as to quickly mix the reagents in the upper and lower layers in the test tube; and the sealing cover is used to prevent the reagents in the test tube from splashing.

[0048] Preferably, see Attachment Figure 3 A heat sink 33 is provided on one side of the interior of the device body 10 .

[0049] Specific use of the present invention:

[0050] First, the staff puts the reagent into the test tube 15, and then seals the upper end of the test tube 15 through the sealing cover 16. The staff puts several test tubes 15 into several placement grooves 14 respectively, and at this time, the test tubes 15 pass through the inner side of the sleeve 18, and the inner side of the rubber ring 19 is in friction contact with the outer side of the test tube 15, so as to limit the test tube 15 inside the sleeve 18.

[0051] Secondly, the staff controls the extension and retraction of the electric telescopic rod 37 through a number of control buttons 11, and the first piston plate 36 of the electric telescopic rod 37 extends upward, and the first piston plate 36 moves upward to squeeze the solution in the first hydraulic chamber 34 into the four second hydraulic chambers 35, and the solution in the second hydraulic chamber 35 pushes the two second piston plates 38 away from each other, and the two second piston plates 38 move away from each other to drive the two elastic rods 39 away from each other, thereby pushing the two relatively test tubes 15 to rotate around the two pairs of rotating shafts 20 respectively, so as to make the several test tubes 15 arranged in an inclined manner, which is conducive to quickly mixing the reagents in the upper and lower layers in the test tubes 15. Among them, each pair of second piston plates 38 moves away from each other to squeeze the two springs 40 to generate elastic force, which is conducive to resetting the two second piston plates 38 close to each other under the elastic force of the two springs 40.

[0052] At the same time, the test tube 15 rotates to push the arc plate 42 to move, and the arc plate 42 moves to squeeze the V-shaped elastic plate 41, and the V-shaped elastic plate 41 squeezes to generate elastic force, and the elastic force generated by the V-shaped elastic plate 41 acts on the arc plate 42, so as to continuously strengthen the friction between the inner side of the arc plate 42 and the outer side of the test tube 15 according to the degree of inclination of the test tube 15, and the second piston plate 38 moves to drive the elastic rod 39 to move to cooperate with the test tube 15 to be supported by the arc plate 42 and the V-shaped elastic plate 41, so as to clamp and fix the upper part of the test tube 15; and the arc elastic member 43 is squeezed and elastic force is generated by the rotation of the test tube 15, so as to squeeze and limit the upper and lower parts of the test tube 15, which is conducive to preventing the test tube 15 from detaching from the placement groove 14. And the sealing cover 16 is used to prevent the reagent in the test tube 15 from splashing.

[0053] Next, the staff controls the stepper motor 17 through the control buttons 11 to start, and the stepper motor 17 starts to drive the circular plate 12 and the disc 13 to rotate, and the rotation of the disc 13 drives the test tubes 15 to rotate. Through the revolution of the test tubes 15 and the tilted arrangement of the test tubes 15, the centrifugal force generated by the rotation of the disc 13 and the tilted arrangement of the test tubes 15 make the reagent move up and down along the inner wall of the test tube 15, so as to quickly mix the reagents in the upper and lower layers in the test tube 15.

[0054] Then, the rotation of the disk 13 drives the pairs of push rods 21 to rotate, and the pairs of push rods 21 rotate by fixing the annular plate 31 with the protrusions 32, and the lower ends of the push rods 21 slide and contact with the outer sides of the protrusions 32, so that the two push rods 21 move upward under the guidance of the protrusions 32. The upward movement of the two push rods 21 drives the two sliders 22 and the rotating shaft 20 to move upward, and the upward movement of the two rotating shafts 20 drives the sleeve 18 to move upward, and the upward movement of the sleeve 18 drives the test tube 15 to move upward through the rubber ring 19. The upward movement of the two sliders 22 squeezes the two hollow elastic members 24 to generate elastic force, and when the lower ends of the two push rods 21 contact the upper side of the annular plate 31, the two sliders 22 and the sleeve 18 move downward under the elastic force of the two hollow elastic members 24, and the sleeve 18 moves downward through the rubber ring 19 to drive the test tube 15 to move downward. Under the guidance of the projection 32 on the push rod 21 and the elastic force of the hollow elastic member 24 , the sleeves 18 and the test tube 15 are shaken up and down, which is beneficial to improving the efficiency of quickly mixing the reagents in the upper and lower layers in the test tube 15 .

[0055] At the same time, the two sliders 22 move upwards and drive the two first push rods 26 to move upwards, and the ends of the two first push rods 26 that are away from each other slide in contact with the inclined surfaces of the two guide blocks 28 that are close to each other, so that the two first push rods 26 are close to each other. The two first push rods 26 approach each other and drive the two pressing plates 30 to approach each other. The two pressing plates 30 approach each other to squeeze the two sides of the rubber ring 19, which is conducive to strengthening the clamping and fixing effect of the rubber ring 19 on the test tube 15, so that in the process of the test tube 15 moving upwards, the two pressing plates 30 approach each other to continuously strengthen the degree of squeezing the rubber ring 19, thereby continuously improving the clamping and fixing effect of the rubber ring 19 on the test tube 15, and preventing the test tube 15 from detaching from the sleeve 18.

[0056] At the same time, the two sliders 22 move upward to squeeze and deform the two hollow elastic members 24 respectively. The two hollow elastic members 24 are squeezed and deformed, so that the solutions in the two hollow elastic members 24 enter the two first push rods 26 respectively through the two telescopic connecting tubes 29. The solutions in the two first push rods 26 push the two second push rods 27 to approach each other. The two second push rods 27 approach each other to further strengthen the degree of squeezing of the rubber ring 19 by the two pressing plates 30, thereby further improving the clamping and fixing effect of the rubber ring 19 on the test tube 15, avoiding the test tube 15 from detaching from the placement groove 14, which is conducive to making the test tube 15 shake up and down to enhance the effect of mixing the reagents.

[0057] Finally, after the reagents in the test tubes 15 are mixed, the staff controls the adjustment components to stop and the stepper motor 17 to stop through the control buttons 11 , and the working solution takes the test tubes 15 out of the placement slots 14 , respectively.

[0058] The reagent mixing processor for medical immunoassay of the present invention is provided with a first hydraulic chamber 34, a first piston plate 36, a second hydraulic chamber 35, a second piston plate 38, and an elastic rod 39. The first piston plate 36 with which the electric telescopic rod 37 is extended moves upward. The first piston plate 36 moves upward to squeeze the solution in the first hydraulic chamber 34 into four second hydraulic chambers 35. The solution in the second hydraulic chamber 35 pushes the two second piston plates 38 away from each other. The two second piston plates 38 move away from each other and drive the two elastic rods 39 away from each other, thereby pushing the two relatively test tubes 15 to rotate around two pairs of rotating shafts 20 respectively, so as to make the plurality of test tubes 15 arranged at an angle, which is beneficial to quickly mixing the reagents in the upper and lower layers in the test tubes 15 up and down. By means of the arrangement of the V-shaped elastic plate 41, the arc plate 42 and the arc-shaped elastic member 43, the test tube 15 rotates to push the arc plate 42 to move, and the arc plate 42 moves to squeeze the V-shaped elastic plate 41, and the V-shaped elastic plate 41 squeezes to generate elastic force, and the elastic force generated by the V-shaped elastic plate 41 acts on the lower arc plate 42, so as to continuously strengthen the friction between the inner side of the arc plate 42 and the outer side of the test tube 15 according to the degree of inclination of the test tube 15, and the second piston plate 38 moves to drive the elastic rod 39 to move to cooperate with the test tube 15 to be resisted by the arc plate 42 and the V-shaped elastic plate 41, so as to clamp and fix the upper part of the test tube 15; and the arc-shaped elastic member 43 is squeezed to generate elastic force by the rotation of the test tube 15, so as to squeeze and limit the upper and lower parts of the test tube 15, which is beneficial to prevent the test tube 15 from escaping from the placement groove 14.

[0059] The reagent mixing processor for medical immunoassay of the present invention makes the reagent move up and down along the inner wall of the test tube 15 by the revolution of several test tubes 15 and the inclined arrangement of the test tubes 15, and the centrifugal force generated by the rotation of the disk 13 and the inclined arrangement of the test tube 15, so as to quickly mix the reagents in the upper and lower layers in the test tube 15 up and down; and the sealing cover 16 is used to prevent the reagents in the test tube 15 from splashing. Then, by setting the slider 22, the top rod 21, the annular plate 31, the protrusion 32, and the hollow elastic member 24, under the guiding action of the protrusion 32 on the top rod 21 and the elastic action of the hollow elastic member 24, the several sleeves 18 and the test tube 15 are shaken up and down, which is conducive to improving the efficiency of quickly mixing the reagents in the upper and lower layers in the test tube 15.

[0060] The reagent mixing processor for medical immunoassay of the present invention has the first push rod 26, the guide block 28 and the pressing plate 30 arranged. The two sliders 22 move upward to drive the two first push rods 26 to move upward. The ends of the two first push rods 26 that are far away from each other are respectively in sliding contact with the inclined surfaces of the two guide blocks 28 that are close to each other, so that the two first push rods 26 are close to each other; the two first push rods 26 are close to each other to drive the two pressing plates 30 to be close to each other. The two pressing plates 30 are close to each other to squeeze the two sides of the rubber ring 19, which is beneficial to strengthen the clamping and fixing effect of the rubber ring 19 on the test tube 15, so that in the process of the test tube 15 moving upward, the two pressing plates 30 are close to each other to squeeze the rubber ring 19 continuously, thereby continuously improving the clamping and fixing effect on the test tube 15, and preventing the test tube 15 from detaching from the sleeve 18. By setting the telescopic connecting tube 29 and the second push rod 27, the two sliders 22 move upward to squeeze and deform the two hollow elastic members 24 respectively. The two hollow elastic members 24 are squeezed and deformed, so that the solutions in the two hollow elastic members 24 enter the two first push rods 26 respectively through the two telescopic connecting tubes 29. The solutions in the two first push rods 26 push the two second push rods 27 to approach each other. The two second push rods 27 approach each other to further strengthen the degree of squeezing of the rubber ring 19 by the two pressing plates 30, thereby further improving the clamping and fixing effect of the rubber ring 19 on the test tube 15, avoiding the test tube 15 from detaching from the placement groove 14, which is conducive to shaking the test tube 15 up and down to enhance the effect of mixing the reagents.
