Drug reconstitution systems and related methods are disclosed herein. A drug reconstitution system may include a first component in a first container in a storage state and a second component in a second container in a storage state. The first component may be selected from a group of a drug product, a diluent, a saline solution, and an IV stabilizing solution ('IVSS'). The second component may be selected from a group of the drug product, the diluent, the saline solution, and the IVSS. The first component may be different than the second component. At least one fluid path may be configured to at least selectively fluidly connect the first container and the second container. An urging assembly may be configured to selectively urge at least a portion of the first component from the first container and into contact with the second component.

Systems and approaches for drug delivery device reconstitution

A wearable drug delivery device includes a housing, a needle assembly at least partially disposed in the housing, and a drive assembly at least partially disposed in the housing and coupled to the needle assembly. The needle assembly includes a needle or cannula and a sterile barrier disposed proximal to the needle or cannula in a first configuration where the sterile barrier is intact. The drive assembly includes a container that contains a medicament to be administered, a first plunger disposed in the container, and a drive mechanism that forces the first plunger to urge the medicament through the container. Upon engaging the drive mechanism, the needle or cannula and the sterile barrier move relative to each other from the first configuration to a second configuration where the needle or cannula breaks the sterile barrier, thereby allowing the medicament to be administered via the needle or cannula.

Hydraulic-pneumatic pressurized chamber drug delivery system

Modular fluid path assemblies are provided that include conduit, coupling, and needle portions of a fluid path fluidly coupled to an outlet of a container. The modular fluid path assemblies further include a needle shield having a tip of the needle embedded therein. So configured, in embodiments, the modular fluid path assemblies can be sterilized, a medicament can be filled in the container, and a stopper inserted in the container so that the pre-sterilized and pre-filled modular fluid path assemblies can have a closed container integrity (CCI) seal.

Modular fluid path assemblies for drug delivery devices

Fluid path assemblies for drug delivery devices and methods of establishing a fluid flow path for drug delivery devices are described that include a needle shield valve member that couples to a reservoir having a needle mounted thereto. The needle shield valve member includes an internal barrier that protects the needle and/or contains a drug within the reservoir until activation of the drug delivery device. Upon activation, there is relative movement between the reservoir and needle shield valve member until the needle pierces the barrier to establish a fluid flow path from the reservoir through the needle shield valve member.

Fluid path assembly for a drug delivery device

Drug delivery devices are configured to include a gas-driven piston assembly having a flexible pushrod, a non-linear guide include a non-linear guide pathway at least partially surrounding the flexible pushrod, a cylinder at least partially surrounding the flexible pushrod, and a piston movable within the cylinder in response to the pressurized gas entering the cylinder. Some arrangements include a roller pushrod guide system and/or a gear pushrod guide system.

Drug delivery system with flexible piston assembly

Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.

Muscle wire escapement activation assembly for a drug delivery device

A drug delivery device includes a housing defining a shell and an inner volume, a container, a drive mechanism, a needle assembly, a fluid flow connection, and a backflow prevention mechanism. The container has an inner volume to contain a medicament to be administered to a user. The drive mechanism is at least partially disposed within the housing and exerts a force to urge the medicament out the container. The fluid flow connection is coupled to the container and the needle assembly and allows the medicament to flow from the container to the needle assembly to be administered. The backflow prevention mechanism is associated with at least one of the container, the fluid flow connection, or the needle assembly and includes at least one flow restrictor to restrict a fluid from flowing from the needle assembly to the container.

Backflow prevention mechanism for drug delivery device

A flexible plunger rod, drug delivery mechanism, drug delivery device, and methods are described that utilize the flexible plunger rod perform drug delivery operations. In embodiments, the flexible plunger rod can be stored in a curved configuration to thereby reduce a footprint of the drug delivery mechanism and device.

Drug delivery mechanism

The devices, assemblies, and methods described herein utilize photoacoustic principals to create a jet of fluid using a ultrasonic resonance member and a pulsed laser light beam. The ultrasonic resonance member is a treated substrate having an liquid interface surface in contact with a fluid. When a pulsed laser light beam is applied to the treated substrate, pressure is generated via induced ultrasonic waves to urge the fluid into a jet stream.

Infusion pump

An insertion/retraction mechanism for a drug delivery device is disclosed. The insertion/retraction mechanism includes a retraction hub, an insertion hub, an insertion/retraction mechanism housing, and a dual torsion spring system. The retraction hub includes a first primary rotational stop and a second primary rotational stop extending radially inwardly from an inside surface. The insertion hub is disposed inside the retraction hub and comprises a first complementary rotational stop and a second complementary rotational stop extending radially outwardly from an outside surface. The dual torsion spring system causes the first primary rotational stop and the second primary rotational stop to selectively engage the first complementary rotational stop and the secondary rotational stop, respectively, and further causes the retraction hub to rotate relative to the insertion/retraction mechanism housing as the insertion/retraction mechanism moves between an initial position, an inserted position, and a retracted position.

Needle insertion-retraction system having dual torsion spring system

A sensing system for determining a position of a plunger within a fluid container. The sensing system includes a light source, a light detector and a controller. The light source is configured to emit light into a barrel wall of the fluid container so that the barrel wall serves as a waveguide to guide the light to travel therein in an axial direction. The light detector is positioned to detect reflected light that was emitted by the light source, traveled through the barrel wall serving as the waveguide, and then reflected off a surface of the plunger. The controller is in communication with the light detector to determine an axial position of the plunger surface based on data from the light detector of the detected reflected light.

Sensing system for detecting a piston in a medical fluid container

A fluid injecting device () generally including a fluid delivery assembly () and a needle-free injecting assembly (). The fluid delivery assembly () delivers or transfers the fluid medicine from a cartridge () into the needle-free injecting assembly () for injecting into a patient. A drive train () applies a force to a piston () inside the cartridge () during the delivery of the fluid to the needle-free injecting assembly () to prevent adhesion or static friction between the piston () and the cartridge (). In addition, sensors can be used to help ensure the proper amount of dosage is transferred to the needle-free injecting assembly, conserve power, reduce leakage during disassembly, among other functions.
