Adjustable plunger assembly for injection devices
A recently granted patent (Publication Number: US11992661B2) discloses an assembly for a firing mechanism in an injection device. The assembly includes a rear cap with an elongate member, a plunger carrier connected to the elongate member, a plunger connected to the plunger carrier, and a plunger driver to move the plunger forward upon release of the connection. The assembly allows for different start positions of the plunger by utilizing multiple connection features on the plunger and plunger carrier during construction. This design flexibility enables precise control over the axial length of the assembly and the positioning of the plunger within the device.
Furthermore, the patent describes a method for constructing the assembly, involving the indirect connection of the plunger to the elongate member through the plunger carrier. By utilizing various connection features, such as recesses, apertures, threads, and abutment surfaces, the method allows for the selection of different start positions for the plunger. The plunger driver, positioned between the rear cap and the plunger, plays a crucial role in driving the plunger forward upon release of the connection. Overall, the assembly and method detailed in the patent offer a customizable and efficient solution for the firing mechanism in injection devices, providing enhanced control and precision in drug delivery mechanisms.
