  • Patent number: 11007316
    Abstract: A device (100) for delivering a medicament into a patient's body by injection into or through the patient's skin, including a main body having a top enclosure (116) and a bottom enclosure (104), a reservoir (160) disposed within the main body for containing the medicament, and an injection needle (152) for penetrating the skin of the patient, the needle (152) having a lumen and selectively communicating with the reservoir (160). The device also includes a pressurizing system (600, 140) for selectively pressurizing the reservoir (160). In a pre-activated position, the pressurizing system (600, 140) contacts and compresses the reservoir (160) to reduce the initial volume of the reservoir (160), thereby allowing for partial filling of the reservoir (160).

  • Patent number: 10973988
    Abstract: In an elongated casing, an active agent container connected to an injection needle can be shifted axially by a spring force. Auto-injectors which are sold or distributed filled and with the springs tensed have to be provided with a needle protecting cap to ensure the sterility of the injection needle. When such a needle protecting cap is removed as preparation for using the auto-injector, a tensile force can be exerted on the active agent container. Therefore, the active agent container comprising the injection needle must be prevented from being undesirably pulled forwards. At least one latching tongue prevents the active agent container from being prematurely shifted with respect to the casing, by abutting a flange arranged on a sliding sleeve which accommodates the active agent container. When the auto-injector is placed onto a person's skin, a needle protecting tube is shifted into the casing, forcing the latching tongue away from the flange and, thus, freeing the travel path for needle movement.

    Abstract: A syringe having a mechanical ejection mechanism. The ejection mechanism includes an actuator and a rotational gear. The actuator has a retractable pawl configured to engage the gear when the actuator is displaced from a non-depressed position into a depressed position. Displacement of the actuator causes the gear to rotate by a predetermined angle. The rotation of the gear is translated into linear displacement of the plunger within the barrel, thereby ejecting a predetermined amount of solution from the barrel.

  • Patent number: 10933188
    Abstract: A fluid delivery device comprises a housing having a fluid reservoir. A needle is in fluid communication with the fluid reservoir in an engaged position and out of fluid communication with the fluid reservoir in armed and storage positions. A proximal end of a biasing member is coupled to the housing and a distal end of the biasing member is configured to deliver a force to the fluid reservoir. A piston member extends through the biasing member and is coupled to the distal end of the biasing member. The piston member is fixed with respect to the housing in a locked position such that the biasing member does not deliver the force to the fluid reservoir and moveable with respect to the housing in a released position such that the biasing member delivers the force to the fluid reservoir. Transitioning the needle from the storage position to the armed position transitions the piston from the locked position to the released position.

    Abstract: An apparatus for delivering fluid from a fluid container comprises a housing to which a fluid container is attachable, a slider movably disposed in the housing and a resilient having a first end connected to the housing and a second end connected to the slider. Upon receiving an external force, the slider moves relative to the housing from a first position toward a second position to deform the resilient member from an original state to a deformed state, and upon release of the external force, the resilient member is allowed to resume to the original state to move the slider toward the first position to urge the slider against the fluid container to deliver fluid from the fluid container under a constant fluid flow rate.

  • Patent number: 10610648
    Abstract: A device (1) for delivering an injectable drug to a patient for example from a conventional syringe (37) with a hypodermic needle. The device (1) provides to a user an audible, visible and/or tactile end of dose indication after all of the medicament has been delivered. The end of dose indication can be provided by releasing energy stored within an energy storage means (3d), energy having been imparted to the energy storage means (39) during the delivery of the injectable drug. The energy storage means (3d) acts upon an end of dose indicator (41) which interacts with another part of the device (1), for example an external housing (3), to produce the end of dose indication.
