A recently granted patent (Publication Number: US11878156B2) discloses an injection device designed for administering medication to patients. The device comprises a housing with retaining arms and ribs, a syringe containing the medication, a needle, and a piston, all radially retained within the housing. Additionally, the device includes a needle guard, a ram with a rod connected to the piston, and a cap with an extension through the main spring. The device features an initial position where the retaining arm prevents the ram from firing, a released position allowing the ram to extend, and a locked position where the retaining arm and lock arm prevent the needle guard from retracting.

Furthermore, the patent details various configurations and components of the injection device, such as the design of the needle guard with windows for the retaining arm, the integration of retaining ribs into the housing, and the presence of lock arms on the ram.
