Description

Technical Field

[0001] This utility model relates to the field of antigen emulsification technology, and more specifically, to an antigen emulsifier. Background Technology

[0002] Immunogen emulsifiers are key equipment in biomedical research and vaccine preparation, primarily used to uniformly emulsify antigens and adjuvants to form a stable emulsion, thereby enhancing the immune response. Existing antigen emulsifiers typically require manual fixing of the syringe to a holder during use. To ensure the syringe is vertical and prevent the stirring rod from bumping against it during agitation, operators need to repeatedly adjust and reposition the syringe, which is inconvenient and reduces the efficiency of antigen emulsification. Secondly, in existing antigen emulsifiers, the stirring rod is usually fixedly connected to the motor drive. When it becomes damaged after prolonged use and needs replacement, it is difficult for operators to quickly disassemble and replace it, increasing the difficulty of maintenance.

[0028] Please see Figure 1-5An antigen emulsifier includes a base 1, a support 2 fixedly mounted on the base 1, a fixed shell 3 movably mounted on one side of the support 2, a support frame 4 fixedly mounted at the lower end of the fixed shell 3, a through hole 5 on the support frame 4, a limiting ring 6 fixedly mounted on one side of the fixed shell 3, a first motor 7 fixedly mounted on one side of the fixed shell 3, the drive end of the first motor 7 extending into the fixed shell 3 and fixedly mounted with a bidirectional lead screw 8, one end of the bidirectional lead screw 8 being rotatably connected to the fixed shell 3, and two clamping seats 9 threaded on the bidirectional lead screw 8, each clamping seat 9 having a clamping plate 10 fixedly mounted on one side, the clamping plate 10 being arc-shaped.

[0029] In this embodiment, when it is necessary to fix the syringe, the syringe head is passed through the through hole 5 and the syringe is placed on the support 4. The limiting ring 6 limits it, thereby initially positioning the syringe so that the syringe is placed directly below the stirring rod 13. The first motor 7 is started, and the first motor 7 drives the bidirectional lead screw 8 to rotate. Since the bidirectional lead screw 8 is provided with two threaded areas in opposite directions, the two clamping seats 9 move in adjacent directions. The clamping seats 9 drive the clamping plate 10 to move, and the syringe is vertically clamped and fixed with the cooperation of the two clamping plates 10.

[0030] Please see Figures 1-5 As one embodiment of the installation of the stirring rod: a second motor 11 is fixedly mounted on the bracket 2. The driving end of the second motor 11 passes through the bracket 2 and is fixedly mounted on the mounting shell 12. A stirring rod 13 is mounted on the lower end of the mounting shell 12. Multiple stirring blades 14 are fixedly mounted on the stirring rod 13. A mounting plate 15 is fixedly mounted on the upper end of the stirring rod 13. An insertion hole 16 is provided on the mounting plate 15. A fixing chamber 17 is provided inside the mounting shell 12. A rotating ring 18 is threaded inside the fixing chamber 17. An insertion rod 19 is fixedly mounted on the rotating ring 18. One end of the insertion rod 19 passes through the insertion hole 16 and is inserted into the mounting shell 12. The other end of the insertion rod 19 passes through the fixing chamber 17 and is fixedly mounted on the handle 20. A lifting groove 21 is provided on one side of the bracket 2. A screw 22 is rotatably mounted in the lifting groove 21. A third motor 23 is fixedly mounted on the bracket 2. The driving end of the third motor 23 extends into the lifting groove 21 and is fixedly connected to the screw 22. A lifting seat 24 is threaded on the screw 22. The end of the lifting seat 24 passes through the lifting groove 21 and is fixedly connected to the fixing shell 3.

[0031] More specifically, when it is necessary to install the stirring rod 13, move the stirring rod 13 so that the stirring rod 13 drives the mounting plate 15 to be inserted into the mounting shell 12. Turn the handle 20, and the handle 20 drives the insertion rod 19 to rotate. The insertion rod 19 drives the rotating ring 18 to rotate. Since the rotating ring 18 is threadedly connected to the fixed chamber 17, the rotating ring 18 moves towards the mounting plate 15 while rotating. The rotating ring 18 drives the insertion rod 19 to move so that one end of the insertion rod 19 passes through the insertion hole 16 and is inserted into the mounting shell 12, thereby installing the stirring rod 13. When using the device, the antigen and adjuvant are placed into the fixed syringe. The third motor 23 is started, which drives the screw 22 to rotate. Since the screw 22 is threadedly connected to the lifting seat 24, the lifting seat 24 drives the fixed shell 3 to move. The fixed shell 3 drives the syringe that is clamped and fixed to move, so that one end of the stirring rod 13 and multiple stirring blades 14 are inserted into the syringe. The second motor 11 is started, which drives the mounting shell 12 to rotate. The mounting shell 12 drives the mounted stirring rod 13 and stirring blades 14 to rotate, thereby stirring the antigen and adjuvant to fully emulsify them.

[0032] In summary, when the entire device is in use or operation: when it is necessary to fix the syringe, the syringe head is passed through the through hole 5 and the syringe is placed on the support frame 4. The limiting ring 6 limits it, thereby initially positioning the syringe so that the syringe is placed directly below the stirring rod 13. The first motor 7 is started, and the first motor 7 drives the bidirectional lead screw 8 to rotate. Since the bidirectional lead screw 8 is provided with two threaded areas in opposite directions, the two clamping seats 9 move in adjacent directions. The clamping seats 9 drive the clamping plate 10 to move, and with the cooperation of the two clamping plates 10, the syringe is vertically clamped and fixed.

[0033] When it is necessary to install the stirring rod 13, move the stirring rod 13 so that the stirring rod 13 drives the mounting plate 15 to be inserted into the mounting shell 12. Turn the handle 20, and the handle 20 drives the insertion rod 19 to rotate. The insertion rod 19 drives the rotating ring 18 to rotate. Since the rotating ring 18 is threadedly connected to the fixed chamber 17, the rotating ring 18 moves towards the mounting plate 15 while rotating. The rotating ring 18 drives the insertion rod 19 to move so that one end of the insertion rod 19 passes through the insertion hole 16 and is inserted into the mounting shell 12, thereby installing the stirring rod 13. When using the device, the antigen and adjuvant are placed into the fixed syringe. The third motor 23 is started, which drives the screw 22 to rotate. Since the screw 22 is threadedly connected to the lifting seat 24, the lifting seat 24 drives the fixed shell 3 to move. The fixed shell 3 drives the syringe that is clamped and fixed to move, so that one end of the stirring rod 13 and multiple stirring blades 14 are inserted into the syringe. The second motor 11 is started, which drives the mounting shell 12 to rotate. The mounting shell 12 drives the mounted stirring rod 13 and stirring blades 14 to rotate, thereby stirring the antigen and adjuvant to fully emulsify them.
