A medical injector with a removable cap
A recently filed patent (Publication Number: US20230310754A1) describes a medical injector with a unique cap design for needle protection. The injector includes a housing and a needle with a sharpened end that extends from the housing. The sharpened end of the needle is covered by a first cap, which is further covered by a second cap.
The second cap has a cap body with a distal end, a proximal end, and an interior wall. The interior wall has at least one protrusion that extends inwardly. The second cap also includes a first wing flange and a second wing flange. The first wing flange extends in a first direction and has a curved proximally directed and convex surface. The second wing flange extends in a second direction different from the first direction and also has a curved proximally directed and convex surface. The second cap is engaged with the first cap through the protrusion(s), and removing the second cap with a distally-directed force simultaneously removes the first cap from the needle's sharpened end.
The second cap engages the first cap through a friction fit, ensuring a secure connection. The interior wall of the second cap defines a cavity in its proximal end, which is sized and shaped to receive at least a portion of the first cap. This design allows for easy removal of the caps while maintaining protection for the needle.
The protrusion(s) on the second cap can be multiple and are adapted to frictionally engage the first cap. They may have a tapered surface to aid in receiving the first cap. The protrusion(s) can be in the form of an annular rib.
A window is defined through the sidewall of the second cap, allowing for visual confirmation of the engagement between the second cap and the first cap. This feature provides additional assurance that the caps are securely connected.
The first cap and the second cap can be made of different materials, with the second cap being harder than the first cap. This choice of materials ensures durability and longevity of the caps.
In addition to the medical injector, the patent also describes a cap remover specifically designed to remove the needle cap. The cap remover has a cap body with a cavity to receive the needle cap. It also includes protrusions, wing flanges, and a viewing window. The cap remover disengages the needle cap from the needle when a distally-directed force is applied.
Overall, this patent presents innovative designs for a medical injector and a cap remover, providing improved needle protection and ease of use.
