Description

Technical Field

[0001] This utility model relates to the field of insulin pen technology, and in particular to a one-button snap-on insulin pen. Background Technology

[0002] Insulin pens eliminate the hassle of drawing insulin from vials with a syringe, saving patients from the embarrassment of injecting insulin in public. They also provide convenience for patients with poor vision or even blindness. While insulin pens are designed for convenient use in public, existing pens are inconvenient to carry and easily lost during activities, preventing patients from using them promptly.

[0003] A search revealed a novel snap-on insulin pen in Chinese patent publication number CN 216908822 U, comprising a mechanical device and a cartridge holder. The mechanical device is located at the lower end of the cartridge holder, and a threaded head is fixedly mounted on the upper end of the mechanical device. The lower end of the cartridge holder is threadedly connected to the threaded head. A dose observation window is fixedly mounted at the center of the front side of the cartridge holder, and a dose scale line is fixedly mounted at the center of the front side of the dose observation window. A main shell is fixedly mounted on the upper side of one side of the cartridge holder. Needle holes are provided on the front and rear sides of the main shell away from the cartridge holder. A protruding hole is provided at the center of the front side of the main shell. A fixing seat is fixedly mounted at the center of the bottom surface of the main shell near the cartridge holder. A loose sleeve is fixedly mounted on the upper end of the fixing seat, and a threaded needle is movably fitted inside the loose sleeve.

[0004] The above-mentioned device has drawbacks in practical use. Although the device avoids the loss of insulin pens during use by setting the threaded needle, in actual use, the user needs to replace the needle of the insulin pen after one or more uses. The device does not have a device to protect the needle, which poses certain safety hazards to the user during the needle replacement process. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this utility model is a one-button snap-on insulin pen, including...

[0024] The main body 100 includes a one-button syringe 101 and a needle 102 disposed above the one-button syringe 101. One end of the needle 102 is detachably connected to the upper end of the one-button syringe 101. A shielding cap 103 is fastened to the upper end of the one-button syringe 101. An installation component is provided on the outside of the one-button syringe 101.

[0025] The protective mechanism 200 includes a silicone cylinder 201 disposed inside the shielding cap 103. Two slots 202 are symmetrically opened on the outer wall of the shielding cap 103. A pressing block 203 is slidably disposed inside the slots 202. A connecting plate 204 is disposed on one side of the pressing block 203. Several pointed rods 205 are fixedly connected to one side wall of the connecting plate 204. One end of each of the pointed rods 205 is inserted into the silicone cylinder 201 for fixing the silicone cylinder 201. An elastic connecting component is provided between the connecting plate 204 and the pressing block 203.

[0026] Depend on Figures 1-4 It is known that the installation components include an anti-loss hanging rod 104, and one side wall of the anti-loss hanging rod 104 is fixedly connected to the outer wall of the one-button syringe 101.

[0027] The anti-loss hanging rod 104 is made of plastic.

[0028] As can be seen from the above, in order to avoid the loss of insulin pen during use, an anti-loss hanging rod 104 is fixedly installed on the outer wall of the one-button syringe 101. Then, before and after use, the user can use the anti-loss hanging rod 104 to hang the device in their pocket to prevent the device from being lost. The structural design is user-friendly.

[0029] Example 2:

[0030] The main body 100 includes a one-button syringe 101 and a needle 102 disposed above the one-button syringe 101. One end of the needle 102 is detachably connected to the upper end of the one-button syringe 101. A shielding cap 103 is fastened to the upper end of the one-button syringe 101. An installation component is provided on the outside of the one-button syringe 101.

[0031] The protective mechanism 200 includes a silicone cylinder 201 disposed inside the shielding cap 103. Two slots 202 are symmetrically opened on the outer wall of the shielding cap 103. A pressing block 203 is slidably disposed inside the slots 202. A connecting plate 204 is disposed on one side of the pressing block 203. Several pointed rods 205 are fixedly connected to one side wall of the connecting plate 204. One end of each of the pointed rods 205 is inserted into the silicone cylinder 201 for fixing the silicone cylinder 201. An elastic connecting component is provided between the connecting plate 204 and the pressing block 203.

[0032] refer to Figure 1 , Figure 3 and Figure 4 As shown, the elastic connection assembly includes shafts 206, one end of each shaft 206 is fixedly connected to one side wall of the pressing block 203, and the side wall of the connecting plate 204 away from the tip rod 205 is provided with a number of slots, and the end of the shaft 206 away from the pressing block 203 is slidably connected in the slot.

[0033] The elastic connection assembly also includes a spring 207, which is disposed between the pressing block 203 and the connecting plate 204, and is sleeved on the outer wall of the shaft 206.

[0034] As can be seen from the above, during use, the silicone cylinder 201 is fixed by the tip rod 205. Furthermore, when the personnel fasten the masking cap 103 with the one-button syringe 101, the needle 102 is inserted into the silicone cylinder 201. After the personnel have used the needle 102 for injection multiple times, the needle 102 needs to be disassembled and replaced. Specifically, the personnel use their fingers to press the pressing block 203, further pressing the pressing block 203 into one side of the groove 202. At this time, the personnel can remove the masking cap 103, and the silicone cylinder 201 will wrap around the needle 102. Then, the personnel can remove the needle 102, replace it with a new needle 102, and further transfer the old needle 102 and the silicone cylinder 201. By setting the silicone cylinder 201, it is easy to protect the needle 102 and reduce the safety hazards when replacing and transferring the needle 102.

[0035] Specifically, after replacement, the staff connects the new silicone cylinder 201 to the tip rod 205, further presses the pressing block 203, and fastens the masking cap 103 to the one-button syringe 101, thus facilitating the use in the next cycle.
