Injection device with interlock for safe medicament delivery
The patent US12036393B2 describes an innovative injection device designed for the precise delivery of medicaments from a syringe. The device features a housing composed of a forward body and a rearward body that are axially interconnected, allowing for relative movement. A drive mechanism, including a plunger, is activated by a trigger to dispense the medicament. A critical safety feature is the interlock system, which has locked and unlocked positions. The interlock is engaged through axial movement of the forward and rearward bodies when the device is pressed against an injection site, ensuring that the drive mechanism cannot be activated unintentionally. The interlock hold arrangement includes interlocking components that align prior to dose delivery, preventing rearward movement of the rearward body when engaged.
Further enhancements to the device include a shroud assembly at the forward end, which is biased forward and moves rearward when pressure is applied against the injection site. This assembly incorporates a cam surface that interacts with a resilient member in the forward body, facilitating the engagement of the interlock hold arrangement. The design also allows for the release of the interlock hold arrangement through the forward movement of the shroud assembly when pressure is relieved. Additionally, the device features a second interlock hold arrangement positioned radially opposite the first, enhancing the overall safety and functionality. The trigger mechanism is conveniently located on the rearward body, allowing for user-friendly operation during the injection process.
