Abstract: A medical connector may include a body having an outer surface and an inner surface defining a lumen of the body, an inlet port defined at a proximal end of the body, and an outlet port defined at a distal end of the body. The medical connector may further include a compressible valve member comprising a normally closed slit and disposed in the lumen and extending through the inner and outer surfaces of the body to an exterior of the medical connector. The compressible valve member may be configured to compress radially inward to open the slit upon insertion of the body into a medical access device, and expand radially outward to close the slit upon disconnection of the body from the medical access device.

Abstract: A method for calculating an infusion rate in a drip chamber includes: providing a housing that receives a fluid, the housing received the fluid at a distal end and expels the fluid at a proximal end, the housing includes a reference mark; receiving, at the proximal end of the housing, a flow controller rotatably coupled to the housing, the flow controller includes an aperture extending therethrough; rotating the flow controller relative to the housing such that the aperture prevents the fluid from traveling therethrough; and determining the infusion rate by measuring a time elapsed until the fluid reaches the reference mark in the housing.

Abstract: An exemplary syringe adapter for coupling with a syringe may include a housing. A needle-free connector may be disposed in the housing. A communication member may be in slidable engagement with the housing. The communication member may be slidable, with respect to the housing, between an unactuated state and an actuated state of the syringe adapter. A cannula may extend from the communication. In the unactuated state, the cannula may be retracted within the needle-free connector. In the actuated state, the cannula may protrude through and axially beyond the needle-free connector.

Abstract: Flow restricting adapters may include a first and second connector portions, to permit coupling of the adapter restricting flow between a catheter and blood collection device, and a post forming an inner lumen for directing blood through the flow restricting device, the post having a length configured to extend through the first connector portion and be positioned within a portion of the blood collection device, such as the needle of a blood collection tube holder, when the flow restricting device is coupled with the blood collection device, the post having an inner lumen to increase flow resistance and reduce shear stress of blood moving through the flow restricting device, thereby decreasing the incidence of hemolysis.

Abstract: A syringe adapter includes a female connector, a body in fluid communication with the female connector, a male connector in fluid communication with the female connector and the body, a passage extending radially through the body and a cannula extending axially through the body and out through the female connector, a first end of the cannula fluidly coupled to an end of the passage disposed within the body. A filter housing containing a filter is fluidly coupled to an end of the passage that is exterior to the body, the filter housing terminating in a vent that is fluidly coupled to the passage. A first fluid path is formed through the cannula, the passage and the vent, and a second fluid path is formed through the female connector, the body, and the male connector, wherein a closed system is provided when the male connector is uncoupled from the medical device.

Abstract: Activatable medicament delivery containers and assemblies are disclosed that can be activated to direct a medicament from the container using an expandable material that causes an expansion chamber to displace the medicament from the container, where the medicament can be directed from the container at a predetermined or use-specific rate, and for a predetermined period of time, and the container being couplable with a dock to form an activatable medicament delivery assembly, where the container can be removably coupled or replace with the dock, and where the dock can be coupled directly to an intravenous fluid delivery device.

Abstract: Fluid connector assemblies with fluid connectors connected via a detachable ring are disclosed. A fluid connector assembly may include a pair of fluid connectors and a ring that couples the pair of connectors. The ring may be configured to detach from either connector upon experiencing a separating force that exceeds a predetermined threshold force. The detachment of the ring may decouple the pair of fluid connectors. When the pair of fluid connectors are connected, fluid may flow between them. When the pair of fluid connectors are disconnected, fluid may not flow.

Abstract: A fluid-fitting tool is disclosed that can align with and rotationally couple with a fluid fitting where the fluid-fitting tool can include a passage and an engagement feature for engaging against the fluid fitting such that when the fluid-fitting tool is spaced apart from the fluid fitting, the fluid-fitting tool can move in a longitudinal direction toward and away from the fluid fitting, and can rotate relative to the fluid fitting around a longitudinal axis of the passage, and when a portion of the fluid-fitting tool and the fluid fitting are rotationally aligned and longitudinally overlap, the fluid-fitting tool can move longitudinally relative to the fluid fitting, and the fluid fitting is rotated when the fluid-fitting tool is rotated around a longitudinal axis of the passage.

Abstract: A pressure detection system includes a body having an internal chamber with input and output ports and a flexible membrane fluidically sealed to an exposed opening of the chamber to prevent a fluid passing through the chamber from passing through the exposed opening. The membrane is configured to change shape responsive to an increase in pressure caused by the fluid within the chamber satisfying a predetermined threshold. In some implementations, the membrane includes or is part of an identification mechanism which moves outwards, away from the chamber, as the pressure increases to indicate the pressure increase. In some implementations, the identification mechanism includes markings on the surface of the membrane, and an image sensing device reads the markings, and provides an indication of a current pressure associated with the fluid in the chamber based on a variation in the markings from a default state.
