Injection Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524986 titled 'Injection Device

Simplified Explanation

The handheld injection device described in the abstract includes a housing containing a cartridge, a dose setting means, a piston rod, a first clicker component, and a second clicker component. The device is designed to provide audible and/or tactile feedback to the user at the end of dispensing a set dose.

• The device includes a dose setting means that allows the user to set a desired dose to be dispensed.
• A piston rod is used to inject the set dose from the cartridge.
• The first clicker component is largely rotationally constrained to the housing, while the second clicker component is rotatable relative to the housing during dose dispensing.
• The clicker components contact each other only at the end of dispensing a set dose to provide feedback to the user.
• The first clicker component can be displaced relative to the housing between a proximal dose setting position and a distal dose dispensing position.

Potential Applications

The technology described in the patent application could be applied in medical devices for administering precise doses of medication, such as insulin pens or other injectable drugs.

Problems Solved

This technology solves the problem of accurately dispensing a set dose of medication while providing feedback to the user to ensure proper administration.

Benefits

The benefits of this technology include improved accuracy in dose dispensing, user-friendly feedback mechanisms, and potentially increased patient compliance with medication regimens.

Potential Commercial Applications

The technology could be commercially applied in the development of advanced injection devices for healthcare settings, pharmaceutical companies, and medical device manufacturers.

Possible Prior Art

One possible prior art for this technology could be existing injection devices with dose setting mechanisms and feedback features, although the specific design elements described in the patent application may be novel.

How does the device ensure accurate dose dispensing?

The abstract mentions a dose setting means and piston rod, but it does not provide details on how these components work together to ensure precise dose administration.

What materials are used in the construction of the device?

The abstract does not mention the materials used in the housing, cartridge, piston rod, or clicker components, which could impact the device's durability and usability.

Original Abstract Submitted

A handheld injection device includes a housing containing a cartridge, a dose setting means being operable in a first direction to set a desired dose to be dispensed, a piston rod being adapted to cooperate with a piston so as to cause a set dose to be injected from the cartridge, and a first clicker component, which is largely rotationally constrained to the housing, and a second clicker component, which is rotatable relative to the housing during dose dispensing. The clicker components are adapted to contact each other only at the end of dispensing of a set dose to thereby provide an audible and/or tactile first feedback to a user. The first clicker component is displaceable relative to the housing between a proximal dose setting position and a distal dose dispensing position.
