The present teachings relate generally to a medical sampling device assembly (10), comprising: a sampling portion (20) disposed at a distal end (12) of the assembly; handle portion (30) disposed at a proximal end (14) of the assembly and including a bias member (32), a locking member (34) coupled to the bias member, and an indicator member (36); an intermediate portion (40) disposed between and interconnecting the sampling portion and the handle portion; and a sampling member (50) slidably disposed within the handle portion, the intermediate portion, and the sampling portion and protruding distally thereof, and in mechanical communication with the bias member; wherein the indicator member is deployed and the sampling member retracts permanently and completely into the sampling portion upon decoupling the locking member from the sampling member.

A medical device having a forwardly-projecting needle and a selectively-movable needle cap that can be variously positioned to cover all or a portion of the needle, depending upon whether the device is, for example, being transported, aspirated or used to inject a therapeutic fluid. The device can optionally be configured to enable retraction of the needle into the body for safe disposal following use.

A syringe is provided. The syringe includes a syringe barrel including an open proximal end, a closed distal end, and a sidewall extending therebetween. The syringe also includes: a plunger having an annular sidewall configured to seal against an interior surface of the sidewall of the syringe barrel, the plunger being configured to move through the syringe barrel in proximal and distal directions; a pump in fluid communication with an interior volume of the syringe barrel, the pump being configured to draw fluid from the syringe barrel; and a nozzle including a lumen in fluid communication with the pump and configured to receive fluid drawn from the syringe barrel by the pump and to expel the fluid through a distal end of the lumen. The pump can be a valve-less piston pump.

The invention relates to a drug delivery device comprising: a syringe with a body from which a needle extends and an inner sheath; a piston rod comprising a piston and an actuation head, a support sheath for holding the body. It is envisaged that the support sheath and the actuation head comprise corresponding indicators.

The present invention relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle, a medicament delivery mechanism and an actuator. The needle is moveable from a retracted position, wherein the needle is fully received in the housing, to an extended position, wherein the needle protrudes out of the housing. The medicament delivery mechanism comprises a reservoir and dispensing member each disposed in the housing, first and second biasing members, and first and second locking members. The actuator is moveable relative to the housing from an initial position to an intermediate position such that the actuator exerts a force on the first locking member to urge the first locking member from a locked state to an unlocked state wherein the first biasing member moves the needle from the retracted position to the extended position. The actuator is moveable relative to the housing from the intermediate position to a second position such that the actuator exerts a force on the second locking member to urge the second locking member from a locked state to an unlocked state wherein the second biasing member moves the dispensing member within the housing to dispense medicament from the reservoir when the reservoir contains medicament.

A pneumatic retractable syringe has a plunger having an interior retraction lumen. The plunger and syringe barrel have cooperating locking elements so that the plunger is locked after use within the syringe barrel. After injection of medicament is completed, the needle is retracted into the lumen by compressed gas that is released from a gas cell within the syringe when the gas cell is ruptured just before the plunger reaches the end of its downstream path of travel.

Described herein are syringe devices, systems and methods. In general, the syringe may include a first chamber and a cartridge movable within the first chamber. The cartridge may include a cartridge chamber and a valve in fluid communication with the cartridge chamber and the first chamber and having an open configuration and a closed configuration. The valve may allow movement of a liquid out of the cartridge chamber while in a open configuration. The cartridge may also include a second end, movable within the cartridge chamber, and a locking mechanism having a locked configuration and an unlocked configuration, the locking mechanism preventing movement of the second end within the cartridge chamber while in the locked configuration.

An assembly for a drug delivery device is provided, wherein the assembly comprises an actuator which is configured to perform a setting movement in order to set a dose and which is configured to perform a dispense movement in order to dispense a dose and a piston rod which is configured to be moved in a distal direction in order to dispense a dose, and a snap feature which is configured to snap into engagement with the piston rod. The snap feature may be configured to inhibit a dispense movement of the actuator and/or a setting movement of the actuator when a maximum amount of medication has been delivered.

Syringe assemblies having a passive disabling system to prevent reuse are provided. According to one or more embodiments, the syringe assembly comprises a barrel, plunger rod and detachable thumb press wherein the plunger rod further comprises flexible locking petals that lock the plunger rod within the barrel, a ramp disposed adjacent to the locking element, and one or more frangible connection or break point at the proximal end of the plunger rod disposed either inside the thumb press or immediately adjacent to the thumb press to separate the thumb press from the main body of the plunger rod when a user applies sufficient proximal force to the plunger rod after it has been locked within the barrel.

A housing blank and an activation member blank for a medicament delivery device are disclosed, with a kit including a housing blank and an activation member blank, and a medicament delivery device assembled from the kit. The housing blank includes a mid portion having a through-opening for receiving a proximal end portion of a medicament container assembly, and first and second legs foldable relative to the proximal end portion. The activation member blank includes a central portion and a first and second arm foldable relative to the proximal end portion.
