A medicament delivery system, including a medicament container and a delay mechanism that is activated prior to completion of medicament delivery from the medicament container. The delay mechanism automatically activates a subsystem or initiates an operation subsequent to completion of medicament delivery.

In an embodiment, an injection simulation device is provided including a housing defining a channel, the housing comprising a proximal end and a distal end, a plunger comprising a plunger rod body having a proximal end and a distal end and a stopper disposed at the distal end of the plunger rod, the plunger movable proximally and distally within the channel; and a friction feature associated with the housing, the friction feature for interfacing with the plunger rod, wherein the plunger moves in a distal direction relative to the housing to simulate medicament delivery and in a proximal direction to reset the injection simulation device, wherein the friction feature optionally causes differential resistance on the plunger rod, when the plunger rod moves in either the distal or proximal direction.

A medicament delivery device configured to provide a variable single dose of medicament is disclosed. The medicament delivery device includes a main body and a syringe arranged in the main body, wherein the syringe comprises a medicament. The medicament delivery device further includes a removable cap and a plunger rod operatively arranged to eject the medicament through a delivery member i.e. an injection needle attached to the syringe. Still further, the medicament delivery device includes a tubular member coupled to the plunger rod. The tubular member is configured to rotate during removing of the removable cap, and the rotation releases the plunger rod thereby allowing the plunger rod to travel a predetermined distance so as to prime the medicament delivery device.

A system and method to enable treatment through cell therapy. The system can enable cell injection such as, for example, injecting beta cells/islets, cartilage cells, fat cells, and others. The system and method ensure that the delivery rate and delivered volume of the material pumped through a tube and into the injection needle is consistent over the course of the start-operation-stop process from run to run. The system and method can automatically stop delivery and alarm if an occlusion is detected during delivery.

A syringe is disclosed. The syringe comprises a plunger and a barrel. The plunger can be rotated relative to the barrel to lock, unlock and/or translate the components relative to each other.

An injection device including: a body including a syringe locator for receiving a syringe; and a firing mechanism including a rear cap, a plunger configured to be axially displaced in a forward direction relative to the rear cap and a driver system for driving the plunger forwards upon activation of the injection device, the firing mechanism configured to be directly or indirectly connected to the body such that an axial spacing of the rear cap and a barrel of the syringe is fixed during operation of the injection device, wherein, the firing mechanism and/or the body include first and second connection features allowing adjustment of a relative axial position of the firing mechanism and the syringe locator during assembly of the injection device.

Fixtures for testing elasticity of drug related methods and related methods are disclosed. In accordance with an example, a method of testing the elasticity of a cannula of a drug delivery device includes securing a barrel of the drug delivery device within a fixture such that the cannula fixed to a distal end of the barrel extends out from the fixture. The method includes applying a lateral force to a distal end of the cannula using a strike member to move the distal end of the cannula a threshold distance. The method includes removing the force from the cannula. The method includes determining a final position of the distal end of the cannula after the force has been removed.

A syringe type ejection device capable of reducing an amount of residual liquid is provided. A syringe type ejection device includes: a barrel; a nozzle disposed to face the barrel; and a core inserted in the nozzle, the barrel having a large-diameter portion provided with a discharge space for discharging liquid, the nozzle being provided with a holding space for holding the core, the holding space being in communication with the discharge space, and the core being inserted in the discharge space.

Syringes are described herein. In certain embodiments, a syringe includes a syringe body, a movable plunger, and a biasing member. The syringe body defines a cavity and a port in fluid communication with the cavity. The movable plunger is disposed within the cavity. The plunger and cavity define a volume. The port is in fluid communication with the volume. The biasing member is coupled to the plunger. The biasing member is configured to urge the plunger toward the port to dispense a fluid stored within the volume at a desired rate.

Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a retention member. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The biasing member is coupled to the first plunger shaft, wherein the biasing member urges the first plunger to advance toward the syringe port. The retention mechanism prevents the biasing member from advancing the first plunger in an engaged position and permits the biasing member to advance the first plunger in a released position.
