Embodiment Construction

[0052] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] Such as Figures 1 to 13 An automatic injection pen, including an injection pen body, the injection front end of the injection pen body is movably provided with a pen cap 6, which is different in that: the injection pen body includes a casing 7, and the casing 7 is provided with an observation window 14. Meanwhile, an inner housing device 9 is arranged inside the outer housing 7 . Specifically, the inner housing device 9 includes an inner housing body, and an inner sleeve assembly 10 is installed at the front end of the inner housing body. In order to facilitate injection and administration, a PFS device is arranged inside the inner sheath assembly 10 . And, cons...

Abstract

The invention relates to an automatic injection pen which comprises an injection pen body, a pen cap is movably arranged at the injection front end of the injection pen body, the injection pen body comprises an outer shell, an observation window is arranged on the outer shell, an inner shell device is arranged in the outer shell, a PFS device is arranged in the inner shell device, and a propelling device is arranged at the rear end of the inner shell device. The propelling device has a forbidding function, so that after injection is finished, effective injection single-time limitation can be achieved, when a user wants to carry out secondary injection, secondary injection is stopped, repeated use of the automatic injector is avoided, and injection safety is improved. The propelling device is provided with a sound production assembly, so that an obvious clamping prompt tone can be generated through collision and friction with a push rod assembly after injection is finished, and a user can know that the injection is finished without staring at the injection condition of liquid medicine in the observation window.

Description

technical field [0001] The invention relates to an injection pen, in particular to an automatic injection pen. Background technique [0002] Existing disposable auto-injectors are very complex in design principles, resulting in a large number of parts, generally more than 15, so the reliability is not high, the assembly is difficult, and the final product cost is too high. [0003] CN110237366A discloses a medical injection device, which includes an outer cylinder and a pen cap. One end of the outer cylinder is provided with a detachable drug storehouse, and a replaceable standard cartridge medicine bottle is arranged in the drug storehouse. The inside of the outer cylinder is close to one end of the drug storehouse. A fixed sleeve is provided, and the inner axial movement of the fixed sleeve is provided with a push rod seat. The inside of the push rod seat is provided with a transmission ring that can be engaged with the end of the transmission rod. Ratchet ring, one end f...
