[0036] In related technologies, an injection pen includes a pen body and a pen cap. To facilitate carrying the injection pen, a pen clip is designed on the syringe to fix the injection pen in a relatively fixed position.
[0037] However, in the relevant technology, the pen cap and pen body are separate, and the pen clip is fixed to the pen body or pen cap and fixed at the end position. During the carrying of the injection pen, because the pen clip is relatively protruding, it is easily scratched by the outside, which makes the part that is fixed to the pen clip easy to separate, resulting in the internal structure of the injection pen being exposed.
[0038] Therefore, how to prevent the pen cap or body from detaching from the protruding pen clip is a technical problem that urgently needs to be solved in this field.
[0039] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0041] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0042] like Figure 1 As shown, some embodiments provide a stable pen-type syringe, including: a pen body 1, a pen cap 2, and a pen clip 3; the pen cap 2 is used to cover the pen body 1 to protect the injection needle and prevent the injection needle from leaking out; the main function of the pen clip 3 is to fix the syringe as a whole for carrying. In addition, unlike related technologies, the pen clip 3 in this embodiment is located close to the gap between the pen body 1 and the pen cap 2. Compared with the pen clips 3 located at both ends of the pen, the pen clip 3 in this embodiment can prevent the pen cap 2 from detaching from the pen body 1, thereby effectively preventing the injection needle from leaking out.
[0043] Please continue reading. Figure 1 ,like Figure 1 As shown, the pen body 1 includes a rotating end 11 and a pen tip 12, and the pen cap 2 has a sealed end 21 and an open end 22. An annular groove 23 is provided on the pen cap 2 near the open end 22. In order to connect the pen body 1 and the pen cap 2 through the pen clip 3, the pen clip 3 is sleeved on the pen body 1 near the pen tip 12, wherein part of the pen clip 3 abuts against the annular groove 23 of the pen cap 2. This way, after the pen cap 2 is sleeved on the pen body 1, part of the pen clip 3 protrudes into the annular groove 23, restricting the pen cap 2 from moving in the opposite direction of the pen body 1, thereby greatly reducing the probability of the pen body 1 and the pen cap 2 detaching.
[0044] Please see Figure 1 and combined Figure 2 and Figure 3 ,like Figures 1 to 3 As shown, the composition of the pen clip 3 is described in detail below. The pen clip 3 includes a positioning ring 31, which is fixedly connected to the pen body 1. A clamping structure 32 is provided on the side wall of the positioning ring 31, which is used to suspend the clamping structure 32 on one side of the syringe.
[0045] Please continue reading. Figure 2 and combined Figure 3 .like Figures 2 to 3As shown, the clamping structure 32 includes a lifting member 321; the lifting member 321 includes two horizontal bars, which are set on the end of the pen body 1 near the pen tip 12. Before using the syringe, the pen cap 2 is removed from the pen body 1. At this time, the position of the horizontal bar is the height at which the user holds the pen body 1 and the outer edge of the little finger needs to stay. This ensures that the user's hand does not slip or jerk when lifted by the horizontal bar during the injection process, thus enhancing the stability of the injection process and reducing the difficulty of injection. One end of the horizontal bar is connected to the positioning ring 31. The other end of the horizontal bar is connected to an arc-shaped support rod 322; the arc-shaped support rod 322 forms a retaining cavity 4 between the pen cap 2 and the outer wall of the pen body 1, and the inner wall of the arc-shaped support rod 322 is used to abut against the surface of the relative fixing member.
[0046] Please continue reading. Figure 3 .like Figure 3 As shown, the ends of the two arc-shaped support rods 322 away from the crossbar are connected by a guide rod 323; the guide rod 323 is U-shaped. The connection position of the guide rod 323 and the arc-shaped support rod 322 forms an angle 324; the angle 324 extends into the annular groove 23. The main purpose of this design is to connect the pen body 1 and the pen cap 2.
[0047] Please continue reading. Figure 3 and combined Figure 4 .like Figures 3 to 4 As shown, the center line of the plane containing the guide rod 323 intersects the side wall of the pen cap 2 at an acute angle. The crossbar, the arc-shaped support rod 322, and the guide rod 323 are designed with these features in mind. To further enhance clamping stability, anti-slip strips 325 are provided on the surface of the arc-shaped support rod 322 facing the pen cap 2 and the outer wall of the pen body 1.
[0048] In summary, by placing the pen clip 3 in the middle of the syringe, the pen cap 2 can be prevented from detaching from the pen body 1, thereby effectively preventing leakage of the injection needle and improving the safety of syringe use; by setting the support 321, the edge on the user's little finger side can have a force platform during injection, improving stability during injection; by setting the arc-shaped support rod 322 and the bend 324, the syringe and the fixing part are prevented from detaching during movement, improving the stability of syringe carrying.
