An assembly of a drug delivery system, comprising: a first component; a second component which is configured to move linearly with respect to the first component; and, a resistance element configured to resist linear movement during transport of the first component with respect to the second component in a closed transport configuration but which is adapted to be overcome during nominal operation of the drug delivery system.

A method of securing an assembly of a drug delivery system, comprising: configuring at least a first component and a second component of the assembly in a closed configuration ready for placement into the drug delivery system; installing an assembly key including a locking element on the assembly to secure the assembly in said configuration; and, transporting the assembly with the assembly key installed.

A system and method for a patch-like, self-contained substance infusion device which can be attached to a skin surface via an adhesive contact surface. A push button activation assembly can then be used to remove an interlock, allowing a disk or Belleville spring assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly. This allows the release of one or more spring-loaded patient needles into the skin surface, and establishes a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.

The subject invention provides a drug delivery device for injecting medicament which includes: a tubular reservoir; a stopper slidably disposed in the reservoir; a spring for moving the stopper in the reservoir; at least one needle, the needle having a distal end for insertion into a patient, and a lumen extending proximally from the distal end, the lumen being in direct or indirect communication with the reservoir; a needle driver for displacing the needle; and, an actuator. Activation of the actuator causes the spring to move the stopper and the needle driver to displace the needle. The needle moves relative to, and separately from, the reservoir with the needle being displaced. Advantageously, with the subject invention, a drug delivery device is provided wherein a needle is moved, relative to the reservoir, in being displaced for injection. This permits control of the needle displacement separate from the reservoir.

The invention relates to an insertion device comprisinga penetrating member (50) connected to transformation means (52), a moving part (38) comprising guiding means (39) which guiding means (39) restrict the movement of the transformation means (52) and guide the penetrating member (50) from a first to a second position in a first direction, i.e. the direction of insertion, towards the injection site, anda stationary housing (30) comprising guiding means (32) which guiding means (32) restrict the movement of the moving part (38). The guiding means (32) guide the moving part (38) in a second direction which is linear and different from the first direction i.e. the direction of insertion.

A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.

A needle hub for a drug delivery device includes a hub body, an activation button, a needle holder and a needle attached to the needle holder, a cannula holder and a cannula attached to the catheter holder, a needle actuation mechanism configured to move the needle holder and the cannula holder from a retracted position to an insertion position and configured to move the needle holder back to the retracted position, and a cannula spring biasing the catheter holder to a retracted position. Movement of the activation button is configured to cause the needle holder and the catheter holder to move from the retracted position to the insertion position, with the needle holder configured to return to the retracted position while the catheter holder remains in the insertion position.

Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

The application describes a protective case for an auto-injector. The medicament contained within these auto-injectors can be susceptible to degradation due to exposure to extreme temperatures and light. Thus, one embodiment of the protective case reduces the rate of heat transfer between the internal storage compartment of the case and the external atmosphere by including particularly configured vacuum chambers. Additionally, as auto-injectors become smaller, portability can be desirable. Thus, another embodiment of the protective case includes low-profile cases that allow the user to keep the auto-injector with them, e.g., by attaching the case to a common everyday item.
