DEVICES AND METHODS FOR FLUID INFUSION, DRAINAGE, AND COLLECTION

Containers for collecting fluid are provided that include a reservoir comprising a plurality of panels enclosing an interior, side panels of the reservoir are movable from an expanded position towards to a compressed position and biased to the expanded position for generating a vacuum within the interior. An elongate housing extends along a top side of the reservoir including a passage extending between proximal and distal ends thereof and communicating with the interior of the reservoir. An elongate member extends through the housing including a distal extension, a proximal extension, and a lumen extending therebetween. One-way valves are coupled to the distal and proximal extensions for permitting fluid flow proximally from the distal extension into the interior of the reservoir via and permitting fluid flow proximally from the proximal extension while preventing fluid flow distally out the distal extension and distally into the proximal extension and lumen.

INFUSION DEVICE WITH RELEASABLE FLUID CONNECTOR

An infusion set system includes a base and a fluid connector removably coupleable thereto. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

VARIABLE FLOW CONTROL DEVICE, SYSTEM AND METHOD
20180008767 · 2018-01-11 · ·

A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.

Tubing retention device
11708923 · 2023-07-25 · ·

Tubing retention systems are described herein. A tubing retention system includes a spigot, a tubing, and a collar. The spigot includes a spigot body and a spigot extension extending from the spigot body, wherein the spigot extension comprises a flared portion opposite to the spigot body and the spigot body and the spigot extension cooperatively define a spigot lumen. The tubing includes an outer surface and a tubing lumen, wherein a coupling portion of the tubing is disposed around the spigot extension, permitting fluid communication between the tubing lumen and the spigot lumen. The collar is disposed radially around the outer surface of the tubing and axially between the flared portion and the spigot body, wherein the collar radially engages the coupling portion of the tubing disposed around the spigot extension to axially and radially retain the tubing with the spigot.

Front-loadable fluid transfer assemblies and related medical fluid transfer systems and methods

Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.
