Injector Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18475927 titled 'Injector Device

Simplified Explanation

The injector device described in the patent application includes a housing with a slot and a locking portion, a needle unit with a needle and a slot engagement portion, and a cartridge with a medicament reservoir. The needle unit is movably mounted in the housing, restricted by the slot, and can be rotated to engage with the cartridge, placing the needle in fluid communication with the reservoir.

• Housing with slot and locking portion
• Needle unit with needle and slot engagement portion
• Cartridge with medicament reservoir
• Needle unit movably mounted in housing, restricted by slot
• Needle unit can be rotated to engage with cartridge, placing needle in fluid communication with reservoir

Potential Applications

The technology described in this patent application could be used in medical devices for administering injections, such as insulin pens or other types of injectors.

Problems Solved

This technology solves the problem of securely locking the needle unit in place while also allowing for easy engagement with the cartridge to establish fluid communication with the medicament reservoir.

Benefits

The benefits of this technology include improved safety and ease of use for patients who need to self-administer injections. The design allows for a secure connection between the needle and the medicament reservoir, reducing the risk of accidental needle sticks.

Potential Commercial Applications

This technology could be utilized in the development of new injector devices for various medical applications, potentially leading to improved patient outcomes and user experience.

Possible Prior Art

One possible prior art for this technology could be traditional syringes with detachable needles, where the needle is manually attached to the syringe before use. However, the design described in the patent application offers a more secure and user-friendly way to connect the needle to the medicament reservoir.

How does this technology compare to existing injector devices on the market?

The article does not provide a direct comparison between this technology and existing injector devices. It would be helpful to know how this design improves upon current options in terms of safety, ease of use, and effectiveness.

Are there any potential limitations or drawbacks to this technology?

The article does not address any potential limitations or drawbacks of this technology. It would be important to consider factors such as cost, manufacturing complexity, and user feedback to fully evaluate the practicality of implementing this design in real-world applications.

Original Abstract Submitted

An injector device includes a housing having a slot with a locking portion and a needle unit that has a needle and a slot engagement portion that extends through the slot in the housing to an external side of the housing. The needle unit is movably mounted in the housing such that movement of the needle unit relative to the housing is restricted by the slot. The injector device also includes a cartridge that is mounted in the housing, the cartridge having a reservoir for medicament. Prior to use of the injector device, the reservoir is sealed from the needle. The slot in the housing is arranged such that the needle unit can be rotated to move the slot engagement portion out of the locking portion such that the needle unit can be moved into engagement with the cartridge to place the needle in fluid communication with the reservoir.
