A recently filed patent (Publication Number: US20230173182A1) describes an auto-injector device that allows for adjustable volume control of medicaments. The device includes a syringe assembly with a needle and a barrel for holding the medicaments. A plunger is positioned coaxially with the barrel and can be adjusted to vary the volume of medicaments to be expelled. This adjustment is achieved by engaging a locking member with the plunger at different positions along its length.

The auto-injector device also includes a housing defined by two body members that are coupled together. Within the housing, there is a Pre-filled Syringe (PFS) holder to secure the syringe assembly. The plunger has an engaging portion along its length, and the locking member engages with this portion at different positions to hold the plunger in place. A spring release arm at the proximal end of the device supports the plunger and a plunger spring.

The locking member has locking teeth that engage with the engaging portion of the plunger, ensuring the spring release arm remains locked in position. A needle guard is also included in the device, which can move the locking member from an engaged position to a disengaged position. A needle guard spring allows for resilient movement of the needle guard.

In the engaged position, the locking teeth hold the plunger away from the distal end of the auto-injector device. In the disengaged position, the needle guard moves the locking member towards the proximal end, releasing the plunger. Additionally, the device features a plunger spring that is compressed between the head portion of the plunger and the locking member. This spring provides the necessary force to expel the medicaments from the barrel.

Overall, this patent describes an auto-injector device with adjustable volume control for medicaments. The device includes various components such as a syringe assembly, plunger, locking member, needle guard, and plunger spring. The adjustable volume control allows for precise dosing, making it potentially useful in medical applications where accurate medication delivery is crucial.
