Description

Technical Field

[0001] This invention belongs to the field of immunoassay technology, specifically a mixing device for a fully automated immunoassay kit. Background Technology

[0002] Immunomagnetic beads are prone to precipitation and need to be kept in a uniform suspension during use. This ensures a uniform quantity is obtained when the reagent needle is drawn up, guaranteeing reaction quality and improving the accuracy of experimental results. Current methods for mixing reagents generally involve manual shaking or placing a test tube containing the immunomagnetic beads on a rotating disk and mixing by repeated rotation.

[0003] When placing a test tube on a rotating disk, it is often clamped by a spring and held in place. However, this method often only clamps the test tube from both sides, resulting in an unreliable grip that makes it easy for the tube to fall off the rotating disk. Additionally, the exposed test tube is easily damaged. Utility Model Content

[0004] This invention provides a mixing device for a fully automated immunoassay kit to address the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] The mixing device for a fully automated immunoassay kit includes a housing, within which a drive motor is fixedly installed. A rotating rod is coaxially fixedly connected to the shaft of the drive motor. A rotating disk is vertically connected to the upper end of the rotating rod. The rotating disk has several vertical outer tubes. A tapered tube, wider at the top and narrower at the bottom, is fixedly installed inside each outer tube. Several slits are opened along the circumference of the side of the tapered tube, extending downward to the lower end face of the tapered tube. Test tubes are clamped through the tapered tubes.

[0007] In use, the test tube is placed inside a conical tube. Due to cracks in the conical tube, the lower part of the tube opens after the test tube is inserted, thereby squeezing the test tube in the opposite direction and fixing it inside the conical tube. Then, the drive motor is started, and the rotation of the drive motor shaft drives the rotation of the rotating disk, thereby rotating the test tube. The drive motor rotates back and forth, thus mixing the contents of the test tube. The conical tube ensures that the test tube will not fall off for a long time, while the outer tube also serves to protect the test tube.

[0008] Preferably, the rotating disk has several circular holes, and the outer tube is disposed inside the circular holes and is rotatably connected to the circular holes via bearings.

[0009] Preferably, the outer tubes are evenly arranged around the circumference of the rotating disk and have multiple concentric rings.

[0010] Preferably, a gear is fitted onto the lower end of the outer tube, and several gear rings are concentrically fixed on the lower part of the outer shell. The gear rings mesh with the gears on the corresponding rings of the outer tube. When the rotating disk rotates, it drives the outer tube to rotate along the rotating rod. The outer tube drives the gear to rotate, and when the gear rotates along the gear rings, it drives the gear to rotate on its own axis, thereby achieving further rotation and mixing of the test tube inside the outer tube.

[0011] Preferably, the bottom surface of the gear ring is vertically connected to several support rods, and the lower end of the support rods is fixedly connected to the inner wall of the bottom surface of the outer casing.

[0012] Preferably, an annular track is fixedly provided along the inner wall of the outer shell, and a slider is provided on the annular track. The slider is fixedly connected to the rotating disk. The cooperation between the annular track and the slider can limit the rotation of the rotating disk while allowing it to rotate, thus preventing the rotating disk from tilting due to the weight of the test tube.

[0013] Preferably, the outer tube has screws vertically connected to both sides, and a U-shaped rod with its U-shaped opening facing downwards is provided on the outer tube. Slots are formed on the vertical sections on both sides of the U-shaped rod, through which the screws pass and are threadedly connected to the compression nut. Pressing down on the U-shaped rod and rotating it to tighten the nut secures the test tube cap, preventing it from popping open and causing liquid to spill out. Loosening the compression nut and then lifting and rotating the U-shaped rod outwards ensures that it no longer obstructs the test tube cap, facilitating the removal of the test tube.

[0014] Preferably, the inner wall of the conical tube is fixedly equipped with rubber anti-slip pads, which can further improve the friction and prevent the test tube from falling off the conical tube.

[0015] Preferably, the outer tubes on the same circular trajectory line have the same diameter, while the outer tubes on adjacent trajectory circles have different diameters, thus enabling clamping of test tubes of different diameters.

[0016] Preferably, the diameter of the outer tube decreases from the outer ring to the inner ring.

[0017] The beneficial effects of this utility model are as follows: Firstly, the use of the conical tube clamping mechanism enables the test tube to be clamped around the entire circumference, achieving a better clamping effect and preventing the test tube from falling off the rotating disk. The outer tube further prevents the test tube from falling off while protecting it. At the same time, the cooperation between the gear and the gear ring ensures that the test tube produces a better mixing effect. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The mixing device of a fully automated immunoassay kit, such as Figures 1-4 As shown, the device includes a housing 1, within which a drive motor 2 is fixedly installed. A rotating rod 3 is coaxially fixedly connected to the shaft of the drive motor 2. A rotating disk 12 is vertically connected to the upper end of the rotating rod 3. The rotating disk 12 has several circular holes evenly arranged around its circumference in multiple concentric circles. An outer tube 4 is disposed within these circular holes and rotatably connected to them via bearings. A tapered tube 5, wider at the top and narrower at the bottom, is fixedly installed inside the outer tube 4. Several slits are formed along the circumference of the tapered tube 5, extending downwards to its lower end. Test tubes are clamped by the tapered tube 5, whose side surface is an elastic plate, achieving a good clamping effect.

[0027] In use, the test tube is placed inside the conical tube 5. Due to cracks in the conical tube 5, the lower part of the tube opens after the test tube is inserted, thereby squeezing the test tube in the opposite direction and fixing it inside the conical tube 5. Then, the drive motor 2 is started, and the rotation of the drive motor 2 shaft drives the rotation of the rotating disk 12, thereby rotating the test tube. The drive motor 2 rotates back and forth in opposite directions, thus mixing the contents of the test tube. Under the action of the conical tube 5, the test tube can be held in place for a long time without falling off, and the outer tube 4 also serves to protect the test tube.

[0028] A gear 6 is fitted onto the lower end of the outer tube 4. Several gear rings 7 are concentrically arranged on the lower part of the outer shell 1. Several support rods are vertically connected to the bottom surface of the gear rings 7, and the lower ends of the support rods are fixedly connected to the inner wall of the bottom surface of the outer shell 1. The gear rings 7 mesh with the gears 6 on the corresponding outer tubes 4. When the rotating disk 12 rotates, it drives the outer tube 4 to rotate along the rotating rod 3. The outer tube 4 drives the gear 6 to rotate. When the gear 6 rotates along the gear rings 7, it drives the gear 6 to rotate on its own axis, thereby achieving further rotation and shaking of the test tube inside the outer tube 4.

[0029] An annular track 8 is fixedly installed along the inner wall of the outer shell 1, and a slider 9 is installed on the annular track 8. The slider 9 is fixedly connected to the rotating disk 12. The cooperation between the annular track 8 and the slider 9 can limit the rotation of the rotating disk 12 while allowing it to rotate, thus preventing the rotating disk 12 from tilting due to the weight of the test tube.

[0030] The outer tube 4 has screws vertically connected to both sides. A U-shaped rod 10 with its U-shaped opening facing downwards is provided on the outer tube 4. Strip grooves 11 are formed on the vertical sides of the U-shaped rod 10. The screws pass through the strip grooves 11 and are threadedly connected to the compression nut. Pressing down on the U-shaped rod 10 and rotating it to tighten the nut secures the test tube cap, preventing it from popping open and causing liquid to spill out. Loosening the compression nut and then lifting and rotating the U-shaped rod 10 outwards ensures that it no longer obstructs the test tube cap, facilitating the removal of the test tube.

[0031] Rubber anti-slip pads are fixedly installed on the inner wall of the conical tube 5 to further improve friction and prevent the test tube from falling off the conical tube 5.

[0032] The outer tubes 4 located on the same circular trajectory line have the same diameter, while the outer tubes 4 on adjacent trajectory circles have different diameters, thus enabling clamping of test tubes of different diameters. The diameter of the outer tube 4 decreases from the outer circle to the inner circle.

[0033] The use of this application firstly utilizes the clamping of the conical tube 5 to achieve a better clamping effect on the test tube, preventing the test tube from falling off the rotating disk 12. The outer tube 4 further prevents the test tube from falling off while protecting it. At the same time, the cooperation between the gear 6 and the gear ring 7 ensures that the test tube produces a better mixing effect.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
