[0002] Chinese Patent No. 2024217695365 discloses a handheld medication dispenser comprising a dispenser handle and a syringe connected thereto. The syringe is fitted with a piston. To prevent the piston from falling into the syringe during transportation, preventing removal, the piston is provided with a baffle. The connection between the baffle and the piston is designed to be easily broken. When the device is needed, the baffle can be snapped off from the easily broken portion.

[0003] However, when the applicant actually produced the above-mentioned products, he found that the above-mentioned structural arrangement had certain defects. On the one hand, it was difficult to open the mold when the above-mentioned structure was produced using a mold, and the scrap rate of the products produced was high. On the other hand, due to the easy breakage of the baffle and the piston part, the baffle was prone to falling off during transportation, which also led to the production of defective waste products.

DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be derived from these drawings without inventive effort.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not limited to the following embodiments.

[0027] Combine Figure 1-Figure 7 As shown, the utility model provides a piston support member, comprising a piston member 1 and a clamping plate 6 detachably connected to the piston member 1 .

[0028] In this embodiment, the piston member 1 includes a rubber head mounting portion 2, a main body portion 3, and a connecting portion 4, with a clamping portion 5 disposed between the main body portion 3 and the connecting portion 4. The rubber head mounting portion 2 includes a top plate 21 and a reinforcing plate 22 fixedly connected to the top plate 21. The main body portion 3 includes an upper plate 31, a lower plate 32, and a second reinforcing plate 33 located between the upper and lower plates 31, 32 and fixedly connected to the upper and lower plates 31, 32, respectively. The connecting portion 4 includes a bottom plate 41 and a third reinforcing plate 42 fixedly connected to the bottom plate 41. The reinforcing plate 22 is fixedly connected to the upper plate 31, and the clamping portion 5 is fixedly connected to the lower plate 32 and the third reinforcing plate 42, respectively.

[0029] In this embodiment, the clamping portion 5 is a cylindrical structure, and the clamping plate 6 is detachably connected to the clamping portion 5. Specifically, the clamping plate 6 has a clamping interface 61, which includes a guide portion 611 and an arcuate portion 612. The arcuate portion 612 cooperates with the clamping portion 5. The clamping plate 6 is also provided with a rough structure 7.

[0030] The piston support member of the present invention can be connected to the piston member 1 using a card plate 6, so that the piston member 1 can be installed in conjunction with the syringe (after the piston member 1 is installed with the rubber head). After the piston member 1 is matched with the syringe, the card plate 6 acts as a limiter. When it is needed, it can be removed from the card plate 6. Compared with the existing technology, the piston support member of the present invention has a lower production difficulty and a higher product yield. It can also greatly reduce the scrap rate during transportation. At the same time, once the card plate 6 is removed, it can be reused.

[0031] The above description is merely one embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
