Description

Technical Field

[0001] The utility model relates to the technical field of botulinum toxin injection, in particular to a botulinum toxin injection pen. Background Art

[0002] Botulinum toxin is a neurotoxin protein produced by Clostridium botulinum during its reproduction process. It is now widely used in clinical practice. Because botulinum toxin is easily inactivated, it needs to be prepared and used immediately during actual clinical use. The common preparation method is to use a syringe to inject the solid botulinum toxin particles in the medicine bottle with a liquid to dissolve the solid particles and then extract them for use. However, since the single injection amount of botulinum toxin is small, even a trace amount, the prepared botulinum toxin liquid may precipitate and become inactivated when it is used again. It is also easily contaminated by bacteria in the air before being used again, which fails to meet the sterility requirements and leads to liquid waste.

[0003] Based on the above description, there is an urgent need for a botulinum toxin injection pen that is easy to dispense aseptically and can be used for multiple injections. Utility Model Content

[0020] Example 1

[0021] See also Figures 1 to 3 The utility model provides the following technical solutions: a botulinum toxin injection pen, suitable for the preparation and injection of botulinum toxin.

[0022] Specifically, Figure 1 and Figure 2As shown, a botulinum toxin injection pen comprises a pen housing 1, a piston rod 2, a first partition plate 3 and a second partition plate 4; the piston rod 2 passes through one end of the pen housing 1; the second partition plate 4 is arranged inside the pen housing 1 at the liquid outlet end away from the piston rod 2; the first partition plate 3 is arranged between the piston rod 2 and the second partition plate 4; the pen housing 1 is divided into a first chamber 11 and a second chamber 12 by the first partition plate 3.

[0023] In this embodiment, the pen is divided into a first chamber 11 and a second chamber 12 by a first partition plate 3, the first chamber 11 is filled with liquid medicine and bursting beads, and the second chamber 12 is filled with botulinum toxin powder; the medicine is prepared before use, and the specific preparation process is: invert the pen housing 1, push the piston rod 2, squeeze the bursting beads through the piston rod 2, thereby releasing the liquid medicine, the liquid medicine is filtered by the first partition plate 3 and contacts with the botulinum toxin powder in the second chamber 12, further shaken to complete the preparation, and then the pen housing 1 is turned back, and the piston rod 2 is further pushed to break the second partition plate 4, and then the prepared botulinum toxin liquid medicine is discharged for injection, thereby achieving aseptic preparation and ensuring the activity of botulinum toxin, so as to facilitate multiple injections.

[0024] Specifically, Figure 1 As shown, the piston rod 2 includes a plug body 21 ; a plurality of convex thorns are arranged on one end of the plug body 21 facing the first partition orifice plate 3 .

[0025] In this embodiment, a plurality of convex thorns are arranged on the surface of the first partition plate 3, so as to facilitate rapid puncture of the bursting beads and achieve rapid release of the drug solution, so as to improve the drug dispensing efficiency.

[0026] Specifically, Figure 1 and Figure 2 As shown, the second separator 4 is provided with a plurality of tear lines.

[0027] In this embodiment, the second separator 4 is provided with a plurality of tear lines, which can not only prevent the botulinum toxin powder from falling out before dispensing and prevent the liquid from rushing out of the inner cavity of the pen shell 1 when the liquid is shaken, but also facilitate the second separator 4 to be more easily broken after the piston rod 1 is pushed, so as to discharge the prepared liquid; further, by distributing a plurality of tear lines between the center and the circumference of the second separator 4, it is further convenient for the middle part of the second separator 4 to be broken through and the medicine is released.
