A needle injection system (NIS) comprised of a unique compartmental arrangement. More specifically, an NIS that utilizes two separate energy storage units, wherein one energy storage unit drives the needle from a first position inside a housing to a second position outside of the housing, and the second energy storage unit applies pressure to the medicament storage container in order expel the medication through the needle. A fluid communication channel is located between the medicament storage container and needle. The fluid communication channel contains a seal that prevents fluid flow to, and fluid communication with, the needle until the device is intentionally activated. The seal can be a geometrical seal or a frangible seal capable of being punctured. The geometrical seal can be comprised of a system of O-rings and a sliding alignment hole, which, when aligned, completes the fluid communication. The frangible seal can face perpendicular to the needle.

An injector device for the percutaneous injection of fluids, such as medications, is disclosed. The device can have a mobile phone case. The mobile phone case can hold an auto-injector cartridge having a trigger, spring-loaded needle and reservoir holding a medication such as epinephrine or insulin. The device mobile phone case can communicate injection data to the phone. The phone can communicate the injection data to an emergency service provider.

A medical agent delivery device may comprise a collapsible reservoir and a base portion including at least one microneedle on a first face and on an opposing second face. Each microneedle on the first face may fluidically communicate with a microneedle on the second face. The device may further comprise an elastomeric housing attached to the first face. The reservoir and the at least one microneedle on the first face of the base portion may be within the elastomeric housing. The device may further comprise a displaceable spacer having a first position in which the spacer supports the reservoir in spaced relation to the at least one microneedle on the first side of the base portion. When the spacer is in a second position, the elastomeric housing may be configured to press the reservoir into the at least one microneedle on the first side of the base portion.

The invention relates to an injection device with a luer fitting. The injection device has a compressible syringe body defining a reservoir. A male luer fitting has a channel therethrough for conducting contents of the reservoir, and a luer tip at an end of said male luer fitting opposing said base end. A first connecting structure is arranged on said male luer fitting between said base end and said luer tip. A shield cap is arranged on the male luer fitting. The shield cap has a second connecting structure interacting with said first connecting structure to prevent inadvertent movement of said shield cap relative to said male luer fitting when said shield cap is arranged at said first position. A first seal is provided for sealing said channel at said luer tip and a second seal is provided for sealing the outer surface and the luer tip.

A compact mechanical pump is provided. The pump is adjustable between a compact form and an expanded form, where the pump can be reduced to a compact form for ease of portability and storage and to the expanded form for use as a pump.

An auto-injector for receiving and operating a syringe. The auto-injector includes a housing for receiving the syringe, the housing comprising a main body and a hinged door operable into an open position and a closed position. The syringe is receivable within the housing when the hinged door is in the open position. At least one charging link is connected between the main body and the hinged door, wherein a connection of the at least one charging link to the main body and/or a connection of the at least one charging link to the hinged door is a slidable connection configured to slide on opening and closing of the hinged door and configured to couple to at least one drive spring for priming of the at least one drive spring on the opening of the hinged door and/or the closing of the hinged door. The at least one drive spring is configured on activation of the auto-injector to drive a plunger driver forward within the auto-injector to operate the syringe received within the auto-injector.

An autoinjector includes a case, a door hingedly coupled to the case and having an open position and a closed position, a plunger slidably disposed in the case, and at least one drive spring applying a biasing force on the plunger relative to the case, wherein the door is operably coupled to the plunger, and wherein rotation of the door from the closed position to the open position moves the plunger from a distal position in the case to a proximal position in the case and compresses the at least one drive spring.

An autoinjector includes a case, a door hingedly coupled to the case and having an open position and a closed position, a plunger slidably disposed in the case, and at least one drive spring applying a biasing force on the plunger relative to the case, wherein the door is operably coupled to the plunger, and wherein rotation of the door from the closed position to the open position moves the plunger from a distal position in the case to a proximal position in the case and compresses the at least one drive spring.

Systems and methods are disclosed that include providing a flat syringe having a substantially flat barrel having a main body portion with substantially flat upper and lower surfaces. The main body portion defines a fluid chamber through the barrel and includes a plunger assembly having a plunger seal that slidably engages the fluid chamber to form a fluid tight seal between the plunger assembly and the barrel. The barrel comprises a width (W.sub.B) that is greater than the thickness (T.sub.B) of the barrel to define the flat profile of the barrel and the syringe. Each of the barrel and the fluid chamber have substantially rounded or beveled rectangular cross-sectional shapes that further define the flat profile of the barrel and the syringe.

An autoinjector includes a case, a door hingedly coupled to the case and having an open position and a closed position, a plunger slidably disposed in the case, and at least one drive spring applying a biasing force on the plunger relative to the case, wherein the door is operably coupled to the plunger, and wherein rotation of the door from the closed position to the open position moves the plunger from a distal position in the case to a proximal position in the case and compresses the at least one drive spring.
