An apparatus includes a housing, a medicament container, an actuator, and a biasing member. The actuator is configured to move the medicament container within the housing when the actuator is moved from a first configuration to a second configuration. The actuator includes a gas container and a puncturer. When the actuator is in the first configuration, a portion of the puncturer is disposed apart from the gas container. When the actuator is in the second configuration, the portion of the puncturer is disposed within the gas container. The gas container has a longitudinal axis offset from a longitudinal axis of the medicament container. The biasing member is configured to bias the actuator toward the second configuration.

A sealable joint including a first component, a second component, and a third component. The first component includes a stem having a bore therethrough for the passage of a fluid. The second component is disposed on the first component, and the third component includes a sealing surface and one or more radially inwardly projecting members. One of the second component and the first component, or a combination of the second component and the first component includes a first flange and a second flange that defines an annular recess therebetween. In a sealing configuration, the second component is received by the third component to form a sealed joint in which at least part of the first flange deforms against the sealing surface, the one or more radially inwardly projecting members are disposed in the annular recess between the first flange and the second flange.

A needleless injector that ejects an injection substance to a target region without using an injection needle, the needleless injector includes: an injector body formed by a resin member; an igniter; a housing part in which the injection substance is accommodated; and a piston that is configured to be moved by ejection energy in a predetermined path, communicating with the combustion chamber, to pressurize the injection substance. A reinforcing member is provided inside the injector body, formed by a metal member to be a tubular member, and extends in an axial direction of the injector body while surrounding at least the igniter and the combustion chamber, the reinforcing member being disposed to be sandwiched between parts of the injector body in a radial direction of the injector body.

The present disclosure relates to relates to medication injection devices, and in particular to systems and methods for on-demand delivery of a non-liquid medication from a wearable medication injection device. Particularly, aspects of the present invention are directed to a device that includes a housing defining a chamber, a piston disposed within the chamber, a needle disposed within the chamber on a first side of the piston, an energetic material disposed within the chamber on a second side of the piston, and a medication strip disposed within the needle. The medication strip includes an injectable substance in a non-liquid form.

The invention discloses systems and methods for generation of microfluidic jets providing a tool for very precise and localized delivery of e.g., medicaments. The proposed solution overcomes shortcomings related to miniaturization of a jet injection technology by implementing laser energy as a driving mechanism and optical fibers for its delivery. Solving the step of miniaturization can allow building new tools compatible with minimally invasive surgical techniques, high parallelization of jet injection units or design of new ergonomic injection devices.

Disclosed is a device for the parenteral delivery of a medication, such as a drug. The device includes upper and lower housings in which the upper housing is configured to move relative to the lower housing as a result of application of an external force to permit the user of the device to control the rate at which the drug is administered.

A needleless injector includes an injector main body, a housing part including an accommodating space in which an injection substance is accommodated, the housing part defining a flow path to enable the injection substance to be ejected to a target region through an ejection port, and an attachment part configured to attach the housing part to the injector main body. The attachment part attaches the housing part to the injector main body, with a distal end side outer surface of the housing part corresponding to an inner surface of the housing part on a distal end side, where a communication portion where the flow path is in communication with the accommodating space is located, pressed in a direction opposite to a movement direction of a pressurizing unit that pressurizes the injection substance toward the ejection port.

The present application provides a self-powered drug-delivery device. The device includes a chamber having a wall. The chamber contains a fluid and is in connection with an administration means. The device also includes a displacement-generating battery cell. The device further includes an electrically-controlled battery unit, which includes the displacement-generating battery cell coupled to the chamber by a coupling means. The displacement-generating battery cell includes an element that changes shape as a result of charge or discharge of the battery cell so as to cause a displacement within the battery unit. The arrangement of the battery unit, the coupling means, the wall, the chamber, and the administration means is such that the displacement derived from the battery unit is conveyed by the coupling means to cause displacement of the wall of the chamber such that the fluid is expelled from the chamber to force a drug towards the administration means.

A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

An apparatus includes a housing, a carrier, and an expandable assembly. The housing defines an opening configured to selectively place a gas chamber of the housing in fluid communication with an exterior volume. The carrier is movably disposed within the housing and is coupled to a medicament container. A proximal surface of the carrier defines a portion of a boundary of the gas chamber. The expandable assembly has a first member and a second member. The first member is coupled to an elastomeric member disposed within the medicament container, and the second member includes a valve portion. The expandable assembly transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The valve portion moves relative to the opening when the expandable assembly transitions from the first to the second configuration, placing the gas chamber in fluid communication with the exterior volume.
