Abstract:
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.
Abstract:
A method and system are disclosed for driving a plunger in a drug reservoir. In some embodiments, a variable friction element interconnects between a pushing shaft and a wall of the reservoir. For example, rotation of a driving element in a first direction relative to the pushing shaft may advance the pushing shaft in the reservoir. The friction element may have increased friction resistance to rotation of the pushing shaft in the first direction in comparison to frictional resistance to advancing the pushing shaft. For example, the increased friction may result from wedging a radial element between the pushing shaft and the wall of the reservoir.
Abstract:
Medical devices including a vial adapter with an inline dry drug module for use with a vial, a needleless syringe and a carrier liquid for filling the needleless syringe with an injection solution for injection to a patient. The inline dry drug modules include a dry drug storage component for storing a dry drug dosage and a uniform carrier liquid distribution component for promoting uniform contact of the dry drug storage component by the carrier liquid to form an injection solution from the dry drug dosage. The inline dry drug modules can include a discrete dry drug storage component and a discrete uniform carrier liquid distribution component or a dual purpose component for both drug storage and uniform carrier liquid distribution. The vial adapters can be provided in vented or non-vented versions.
Abstract:
A power supply contact is mountable on a base of a device having a geometry for receiving a power supply and for surface installation of a printed circuit board. The power supply contact includes a base plate mountable on the base of the device, a rail extends upwardly from the base plate, a power supply terminal and an adaptor connecting the rail to the power supply terminal. The rail is in electrical contact with the printed circuit board and the power supply terminal is in electrical contact with the power supply when the printed circuit board and the power supply are installed in the device.
Abstract:
Inline liquid drug medical device having a longitudinal device axis, a housing with a linear displaceable sliding flow control member displaceable along a transverse bore from a first flow control position for establishing flow communication between a first pair of ports for liquid drug reconstitution purposes to a second flow control position for establishing flow communication between a second pair of ports for liquid drug administration purposes, and a manually operated actuating mechanism for applying a linear displacement force for urging the flow control member to slide along the bore from its first flow control position to its second flow control position.
Abstract:
An apparatus (110) includes an activation mechanism (20) and a safety latch (122). The activation mechanism is operative to deploy a needle (116) to protrude out of a housing (112), the needle (116) having a longitudinal axis. The safety latch (122) is movably mounted on the housing (112) and formed with a needle opening (129) to allow the needle (116) to pass therethrough. The safety latch (122) has a first position wherein the needle (116) is aligned to pass through the needle opening (129) and a second position wherein the safety latch (122) is moved with respect to the housing (112) such that the needle (116) is blocked from movement in a direction parallel to the longitudinal axis thereof by a portion of the safety latch (122) distanced from the needle opening (129).

Abstract:
Valve assemblies for use with a liquid container and a drug vial for enabling an initial transfer of liquid contents from the liquid container to the drug vial for liquid drug formation purposes and subsequent transfer of liquid drug contents from the drug vial to the liquid container for administration purposes. Liquid drug transfer sets can include a valve assembly pre-attached to a liquid container. Alternatively, liquid drug transfer sets can include a valve assembly packaged in sterile blister packaging ready for attachment to a liquid container prior to use.
Abstract:
A status of a battery operated infuser may be detected by measuring a controlled input parameter. The measurement may be used to determine a magnitude of the input parameter and a parameter of the control. For example, control of power input to a motor may be by pulse density modulation. An integral of current over time may sever as a measure of current magnitude and pulse density. The result of the integral may be used to determine the status of the injector. The status may include normal functions for example start of pumping and/or malfunctions such as occlusion or drive disengagement.
Abstract:
In some embodiments, a power terminal is in electrical connection to a power supply terminal, and a printed circuit board is supplied with a board to power contact. Bringing the board to power contact together with the PCB contact causes an electrical connection between the power supply and the PCB. In some embodiments the electrical connection resists disconnection from the PCB contact without requiring an external force on the PCB. In some embodiments the PCB-to-power-contact and the PCB contact are brought together in a direction perpendicular to a plane of the PCB. In some embodiments the PCB-to-power-contact includes fingers with grasp the PCB contact on two sides.
