Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an insulin injection pen. Background Technology

[0002] The operating steps for using an insulin pen are as follows: First, remove the pen from a refrigerator at 2-8℃ and allow it to reach room temperature. Gently pull outwards to remove the pen cap. Second, take a new disposable needle, remove the protective film from the needle, and screw the needle directly onto the pen body. Third, remove the outer cap of the needle (do not discard it, as it will be used after the insulin is finished); remove the inner cap of the needle and discard it. Fourth, adjust the dose selection knob until the airflow check mark aligns with the pointer, and the next mark after 0 (no numerical display is shown; this is for venting air). Fifth, hold the pen with the needle tip pointing upwards and gently tap the pen body several times with your finger to allow air bubbles to gather at the top of the cartridge. Sixth, keeping the needle tip pointing upwards, fully push the injection button to return the dose scale to 0. One drop of insulin should appear at the needle tip. If no drop appears, repeat the above two steps, but do not exceed four times. If no insulin droplets appear, replace the needle and repeat the above steps once. If no droplets still appear, do not use the pen, as this indicates that the pen is damaged and must be replaced with a new one.

[0003] In the above steps, the fifth step requires holding the injection pen and flicking the pen barrel with your fingers multiple times. Over time, this operation can cause some damage to the fingers. Moreover, the force of flicking with the fingers is limited and difficult to control, which increases the number of flicks. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing injection pens require the user to flick the pen barrel several times with their finger before use to expel internal air, which causes damage to the fingers with prolonged use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An insulin injection pen includes a pen body and a pen cap for use therewith. An elastic clamping part is fixedly connected to the outer surface of the pen cap near its top, and a spring ball is fixedly connected to one end of the elastic clamping part near the pen body.

[0007] Furthermore, the elastic clamping part includes a base, which is fixedly connected to the pen body. An arc-shaped spring is also provided at the bottom of the base, and a striking ball is fixedly connected to one end of the arc-shaped spring away from the base.

[0008] Furthermore, the arc-shaped spring sheet has a bent portion located near the base.

[0009] Furthermore, the arc-shaped spring is embedded in the notch of the base and fixed with bolts.

[0010] Furthermore, the pen cap is a cylindrical type adapted to the end of the pen body, with a top cover threaded to its top.

[0011] Working principle and beneficial effects: By setting an elastic clamping part on the outer surface of the pen cap, and setting a snap ball at the end of the elastic clamping part, the snap ball is pulled away from the pen body. After releasing the hand, the snap ball quickly returns to its original position and impacts the pen body under the action of the elastic clamping part, which replaces the traditional hand snapping and reduces wear and tear on the fingers.

[0015] The present invention can be better understood from the following embodiments.

[0016] The structures, proportions, and sizes shown in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0017] like Figure 1-2 As shown,

[0018] An insulin injection pen includes a pen body 1 and a pen cap 2 for use therewith. An elastic clamping part 3 is fixedly connected to the outer surface of the pen cap 2 near its top. A spring ball 4 is fixedly connected to one end of the elastic clamping part 3 near the pen body 1. The elastic clamping part 3 includes a base 31, which is fixedly connected to the pen body 1. An arc-shaped spring piece 32 is also provided at the bottom of the base 31. The spring ball 4 is fixedly connected to the end of the arc-shaped spring piece 32 away from the base 31. By providing an elastic clamping part 3 on the outer surface of the pen cap 2, and a spring ball 4 at the end of the elastic clamping part, pulling the spring ball 4 away from the pen body 1 and then releasing it causes the spring ball 4 to quickly return to its original position and impact the pen body 1 under the action of the elastic clamping part 3, thus replacing the traditional method of injection. The traditional spring mechanism reduces wear on the fingers. The curved spring 32 has a bent portion 5 near the base 31. The bent portion 5 increases the deformation of the curved spring 32 and can store the force generated by the bent portion 5 when it is broken off. It is released during the rebound to improve the rebound effect. In order to prevent the entire pen cap 2 from becoming unusable if the bent portion 5 breaks, the curved spring 32 is made detachable. The specific structure is as follows: the curved spring 32 is embedded in the notch of the base 31 and fixed with bolts. In order to prevent the gas venting effect from being unsatisfactory due to the sealing of the pen cap 2, the top cover 6 can be unscrewed when venting. The specific structure is as follows: the pen cap 2 is a cylindrical shape that fits the end of the pen body 1, and its top end is threaded to the top cover 6.
