Description

Pen cap integrated insulin injection pen

Technical Field

The utility model relates to a pen cap integrated insulin injection pen.

Background

The cap of the existing insulin injection pen and the pen body are mostly split, the split type defect is that the cap of the pen is easy to lose after being pulled out, the cap of the pen is easy to loosen and take off from the pen body when being carried, and if the cap of the pen is not completely separated from the pen body after being loosened, an included angle is easily formed between the cap of the pen and the pen body, so that a needle head is easily broken.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pen cap disjunctor formula insulin injection pen aims at solving above-mentioned problem.

In order to achieve the purpose, the technical scheme of the utility model is to design a pen cap integrated insulin injection pen, which comprises a pen body, a pen cap, a chute, a slide block, a needle seat, a needle head, a first sleeve, a second sleeve, a spring, a needle outlet hole and a clamping groove;

the side walls of two sides of the pen body are provided with sliding chutes, the bottoms of the sliding chutes are provided with clamping grooves, and the clamping grooves are communicated with the sliding chutes and form a Z shape; the inner wall of the pen cap is provided with a sliding block capable of sliding in the sliding groove; a needle outlet hole is formed in the center of the bottom of the pen cap; the bottom of the pen cap is provided with a second sleeve; the needle base is positioned at the front end of the pen body, and the needle head is connected with the needle base; the spring is sleeved on the needle base, and the needle head penetrates through the spring; a first sleeve is arranged outside the needle base; and two ends of the spring are respectively positioned in the first sleeve and the second sleeve.

Initial state, slider embedding draw-in groove push away a bit inwards with the cap for during the use, make the slider leave the draw-in groove, then the cap violently rotates, makes the slider get into the spout, then the finger upwards lifts the cap for a brush, and the slider shifts up, and the spring compression, syringe needle pass out the pinhole, then inject to prick the needle. After injection is finished, the finger is released, the pen cap moves downwards under the action of the spring, finally the sliding block reaches the bottom of the sliding groove, the pen cap is rotated, the sliding block enters the clamping groove, the sliding block continues to downwards reach the bottom of the clamping groove, and the needle head returns to the inside of the pen cap in the process.

The utility model has the advantages and the beneficial effects that: the utility model relates to a cap disjunctor formula insulin injection pen simple structure, convenient to use can prevent that the cap from breaking away from the body of a pen, has reduced the step that conventional injection pen must dismantle the cap before the injection.
