Gas-driven drug delivery device with flexible pushrod assembly
The granted patent US12070582B2 describes a gas-driven drug delivery device designed to efficiently administer medication. The device comprises several key components, including a drug container with a drug outlet, a plunger that is slidably coupled to the container, and a gas chamber that holds pressurized gas. Central to the device's operation is a piston assembly, which features a flexible pushrod connected to the plunger, a non-linear guide with a pathway surrounding the pushrod, and a cylinder that includes a gas inlet for fluid communication with the gas chamber. The piston moves within the cylinder's bore in response to the pressurized gas, facilitating the drug delivery process.
Further claims detail specific configurations and materials used in the device. For instance, the bore of the cylinder can be oriented parallel or perpendicular to the drug container's longitudinal axis, and the bore diameter is designed to be larger than that of the flexible pushrod. The flexible pushrod may be constructed from materials such as pre-tensioned stainless steel or polymer tubing. Additionally, the non-linear guide pathway can feature uniform or variable curvature and may include low-friction materials to enhance performance. The design also incorporates features like a pushrod support and a plunger coupling that optimizes the force distribution from the pushrod to the plunger, ensuring effective drug delivery.
