A sampling device includes a container having a body defining a chamber and an opening to the chamber. A septum is bonded to the container to cover the opening and hermetically seal the chamber. The septum has an adherent layer with a first thickness and including a material configured to adhere to a rim of the container to provide a hermetic seal with the container. A metallic foil layer having a second thickness is coupled to the adherent layer. An elastomeric layer having a third thickness is coupled to the metallic foil layer to position the metallic foil layer between the adherent layer and the elastomeric layer. The third thickness is greater than the sum of the first thickness and the second thickness.

A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

A liquid injection device includes: a syringe that comprises a barrel part configured to be filled with a liquid, and a needle attached to a distal portion of the barrel part and configured to discharge the liquid, a cap that covers the needle; a housing that covers at least a base end part of the syringe; and a step part that is formed on an outer peripheral surface of the cap or between the housing and the cap, the step part protruding farther outward than a side surface of the barrel part. The step part is configured to engage with a lower surface of a notch part that extends laterally inward from an outer edge of a flange part of a container such that the cap is removable from the housing by the notch part.

A needle-equipped outer cylinder includes: a needle tube; a joining member comprising: a needle tube accommodation hole that accommodates a proximal end side portion of the needle tube and penetrates the joining member from a distal end of the joining member to a proximal end of the joining member, and a joining outer peripheral portion provided on an outer peripheral portion of the needle tube accommodation hole; and an outer cylinder member comprising: a distal end joint that comprises an inner cavity that receives the joining outer peripheral portion of the joining member from a distal end side, and a projection located at a proximal end portion of the inner cavity and projecting into the inner cavity. The joining member comprises, at a proximal end portion of the joining member, an abutment portion that abuts the projection of the outer cylinder member.

A drug delivery device configured to provide a dose of a first medicament followed by a dose of a second medicament is disclosed. The device includes a main exterior body and an interior body. The device further includes a dual-chamber reservoir with (i) a first chamber holding the first medicament and (ii) a second chamber holding the second medicament. The device also includes a needle and a plunger. After activation of the device, the plunger is configured to (i) move the dual-chamber reservoir a given distance in a distal direction with respect to the interior body so that a distal end of the needle extends out of the interior body and (ii) after moving the dual-chamber reservoir the given distance, move in the distal direction with respect to the dual-chamber reservoir so as to eject from the needle the first medicament followed by the second medicament.

The present specification relates to a subassembly for a drug delivery device, the subassembly comprising: a housing adapted to contain a drug container with a needle, a cap, and a spacer, wherein the housing has an inner surface forming a cavity configured to retain the drug container, wherein the cap is configured to be releasably connected to the housing, and wherein the spacer is arranged between the cap and the housing.

A multiple carrier injection system includes an adapter, having at least one arm, and a pen needle assembly. The pen needle assembly includes a hub retaining a needle and a bullet having a cover to seal the bullet, where the bullet encloses the hub in a first position. The arm engages the adapter to the hub, and the arm causes the hub to rotate within the bullet to move the hub into a second position.

A needle assembly for medical or surgical use is disclosed, such as for hemodialysis. A representative needle assembly comprises an outer needle assembly and an integral needle tip protector. A representative outer needle assembly comprises: an outer needle comprising: a first lumen; a first aperture with a sharp needle tip at a first distal end of the outer needle; and a second aperture arranged opposite the first aperture. In another embodiment, the outer needle has a longitudinal slot and the integral needle tip protector includes a sliding connector which is slidable in the longitudinal slot. The integral needle tip protector is arranged within the first lumen and moveable between a retracted configuration and an extended configuration, and comprises: a needle tip cover arranged to shield the sharp needle tip in the extended configuration, the needle tip cover having a smooth or beveled distal surface forming a blunt tip.

A method includes moving an actuation lock of a medical injector from a first position to a second position. The actuation lock has an extended portion disposed between a shoulder of a housing and the base when the actuation lock is in the first position. The extended portion is spaced apart from the base when the actuation lock is in the second position. A distal end portion of a base, which is movably coupled to an end portion of the housing, is placed into contact with a body. The base is actuated after the placing to release an energy from an energy storage member within the housing to produce a force to move a needle from a first needle position to a second needle position. At least a portion of the needle extends through the base when the needle is in the second needle position.

A connector for connecting a medical injection device having a distal tip, a needle extending from the distal tip and a sleeve extending around the tip comprising an inner threaded portion, to a container including a collar closed by a pierceable septum, including: a proximal part configured to sealingly engage the tip of the injection device so as to enclose at least a part of the needle; a distal part configured to be connected to the container, including a skirt configured to extend around the needle when the connector is connected to the injection device; and a needle shield configured to be mounted on the needle, so as to sealingly enclose at least the tip of the needle, the needle shield being configured to be pierced by the needle inserted via the opening for sealingly enclosing said needle.
