Description

Technical Field

[0001] This utility model relates to the field of plasma mixing technology, and in particular to a plasma mixing device for tetanus immunoglobulin. Background Art

[0002] Tetanus is a serious infectious disease caused by toxins produced by Clostridium tetani. Timely administration of tetanus immunoglobulin is a key measure for the prevention and treatment of tetanus, especially after injury. Timely administration of immunoglobulin can effectively prevent fatal tetanus infection. However, the supply of tetanus immunoglobulin in China has always been insufficient. This is mainly due to the complex extraction process of traditional immunoglobulins and poor mixing, which often results in unsatisfactory purity and efficacy of the product.

[0003] In the traditional production process of tetanus immunoglobulin, plasma homogenization is a crucial step. The quality of homogenization directly affects the purity and activity of the immunoglobulin. Most existing homogenization devices and methods use simple stirring or shaking, which is not only inefficient but also prone to uneven distribution of plasma components, thus affecting the quality and efficacy of the final product.

[0018] The following is in conjunction with the appendix Figures 1-4 The specific embodiments of this utility model will be described in further detail.

[0019] This utility model includes a base plate 5, which is placed on a workbench. A slide table 4 is slidably connected to the top of the base plate 5, allowing the slide table 4 to move left and right on the top of the base plate 5. A drive assembly is located inside the slide table 4, and a support rod 14 is located at the top of the drive assembly. The drive assembly can drive the support rod 14 to rotate. The support rod 14 is rotatably connected to the slide table 4. A guide assembly is located at the top of the support rod 14, and a transmission rod 11 is located at the top of the guide assembly. The support rod 14 can drive the guide assembly to achieve the reciprocating forward and reverse rotation of the transmission rod 11. A support platform 3 is rotatably connected to the outside of the transmission rod 11, and the bottom of the support platform 3 is fixedly connected to the top of the slide table 4. The support platform 3 supports the rotation of the transmission rod 11. A cylinder 2 is fixedly connected to the top of the transmission rod 11, and a cap 1 is threadedly connected to the top of the cylinder 2. The inside of the cylinder 2 can be used to store a blood plasma container. By rotating the cap 1, the cap 1 moves downward to fix the container inside the cylinder 2. 1. The drive assembly drives the cylinder 2 to reciprocate in both forward and reverse directions to mix the plasma inside. A disc 16 is located on the rear side of the drive assembly, and a cylindrical rod 17 is located on the rear side of the disc 16. A limit frame 18 is slidably connected to the rear side of the cylindrical rod 17. The bottom of the limit frame 18 is fixedly connected to the base plate 5. The drive assembly drives the disc 16 to rotate, which in turn drives the cylindrical rod 17 to rotate in a circle. Since the base plate 5 and the limit frame 18 are fixedly connected, the position of the limit frame 18 is fixed. The rotation of the disc 16 compresses the inside of the limit frame 18 through the cylindrical rod 17. When the disc 16 rotates clockwise, it drives the cylindrical rod 17 to rotate clockwise. Under the action of the limit frame 18, the disc 16 and the slide table 4 are pushed to the left. As the disc 16 continues to rotate, the slide table 4 can move back and forth. At this time, the cylinder 2 will periodically rotate forward and reverse as it moves back and forth with the slide table 4, which improves the efficiency of plasma mixing.

[0020] The drive assembly includes a motor 10, a first bevel gear 12 fixedly connected to the rear side of the motor 10, a second bevel gear 13 meshing with the top of the first bevel gear 12, and the top of the second bevel gear 13 fixedly connected to the bottom of the support rod 14. When the motor 10 rotates, it drives the fixedly connected first bevel gear 12 to rotate, and the rotation of the first bevel gear 12 drives the meshing second bevel gear 13 to rotate, and the second bevel gear 13 drives the support rod 14 to rotate.

[0021] The first bevel gear 12 is fixedly connected to the rear side of the shaft 15, which is rotatably connected to the inside of the slide table 4. The rear side of the shaft 15 is fixedly connected to the disc 16. The first bevel gear 12 drives the rear shaft 15 to rotate, and the shaft 15 drives the fixedly connected disc 16 to rotate.

[0022] The guiding assembly includes a turntable 6, the bottom of which is fixedly connected to the top of a support rod 14. The support rod 14 can drive the turntable 6 to rotate. The turntable 6 has a groove inside, an external gear ring 7 on the outside of the groove, and an internal gear ring 8 on the inside of the groove. A spur gear 9 is engaged between the internal gear ring 8 and the external gear ring 7. The spur gear 9 can mesh with the external gear ring 7 or the internal gear ring 8 in stages. When the turntable 6 rotates circumferentially, the internal gear ring 8 first meshes with the spur gear 9, driving the spur gear 9 to rotate. After the turntable 6 rotates 180 degrees, the internal gear ring 8 will disengage from the spur gear 9, and then the external gear ring 7 will begin to mesh with the spur gear 9, driving the spur gear 9 to rotate in the opposite direction. The stroke of the external gear ring 7 is longer than that of the internal gear ring 8. The number of forward and reverse rotations of the spur gear 9 are not the same, which makes the flow of the internal plasma irregular and better mixed. The top of the spur gear 9 is fixedly connected to a transmission rod 11, which drives the cylinder 2 to rotate.

[0023] In use, the drive assembly and guide assembly work together to achieve the reciprocating forward and reverse rotation of the cylinder 2 driven by the transmission rod 11. This periodic rotation effectively improves the mixing efficiency of plasma in the bottle. The entire device is driven by the motor 10, realizing automated operation, reducing manual intervention, improving work efficiency, and reducing the difficulty of operation. The turntable 6 in the guide assembly is designed to achieve the forward and reverse rotation of the transmission rod 11 through the staged meshing of the internal gear ring 8 and the external gear ring 7 with the spur gear 9. The different number of forward and reverse rotations make the flow of plasma in the bottle irregular, thereby improving the mixing effect. While the slide table 4 moves back and forth on the base plate 5, the cylinder 2 also performs periodic forward and reverse rotation. This compound motion further enhances the mixing effect of plasma.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
