摘要： 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.

摘要： Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.

摘要： Bypass elements for medical valves and methods of using the same are disclosed. Embodiments of the invention include an insert having a tip that is adapted to displace a valve element without penetrating it, and a lumen that fluidly communicates with a lumen of a valve housing distal to the valve element when the bypass element is engaged. Bypass elements are used, in certain embodiments, to facilitate fluid pressure and ECG signal measurements through implanted medical devices including catheters.

摘要： A multi-use intravenous infusion assembly is presented which includes a septum actuator having various features to prevent over-insertion of the septum actuator through a slit in a blood control septum. By preventing over-insertion of the septum actuator, the slit of the septum is able to repeatedly self-close following removal of an external Luer device. Thus, the intravenous infusion assembly may be used repeatedly without exposing a clinician to blood and other infusion fluids.

摘要： In a blood-flow-path connector (10) and blood bag system (12), a blocking part (74) is provided in a hollow section (68c) in a tubular body (68), and a communicating part (70) that is axially movable within the hollow section (68c) is disposed. By moving the communicating part (70) relative to the tubular body (68) in a pushing direction, the blocking part (74) is penetrated or pressed to be opened; thus, a flow-path in the tubular body (68) and a flow-path in the communicating part (70) come to communicate with each other.

摘要： A valve assembly is provided which includes a housing having an inlet end and an outlet end and defining a fluid channel and a central chamber. A dissolvable valve member is positioned to obstruct flow through the channel within the chamber. The dissolvable valve member is formed of a material which is dissolvable at a predetermined rate upon contact with a preselected fluid. The preselected fluid is selected from the group consisting of blood, urine, saline and antimicrobial solutions. The dissolvable valve member can be formed from a fluid soluble glass or a starch based material.
