Abstract
Described herein are devices for delivering at least two different medications without requiring disconnections and reconnections of medication syringes. In some embodiments, the devices can accommodate at least two syringes simultaneously. In some embodiments, the device can be torqued while delivering the at least two different medications without loosening the outlet port from an intravenous line the device is hooked up to.
Core Innovation
The invention provides a device for delivering at least two different medications using a body section with a first inlet port and a second inlet port. The first inlet port includes an anti-reflux valve and is operably connected to a first smaller pore filter, while the second inlet port includes an anti-reflux valve and is operably connected to a second larger pore filter. At least one additional inlet port is connected to the first filter, enabling multiple formulations to be delivered from multiple inlet ports into a filtering arrangement.
The device includes a rotating outlet port with a collar that surrounds the outlet port. The collar includes a ratcheting mechanism having a gear including teeth and spaces between the teeth, where the gear runs around an internal circumference of the collar. Pawls are locked into the spaces between the teeth, and the pawls are only rotatable within the spaces between teeth. This structure enables the rotating outlet port to be joined to the first filter and the second filter by a y-connector.
The rotating outlet port is configured to connect to an intravenous line such that the intravenous line is only allowed to disengage from the rotating outlet port by holding the collar when disconnecting the intravenous line. The device is configured so it can be torqued while delivering the at least two different medications without loosening the rotating outlet port from the intravenous line. The described system further supports delivery configurations intended to reduce repeated disconnections and to allow operation during simultaneous administration via the rotating connection.
Claims Coverage
The independent claim (clm-00001) covers a multi-inlet, dual-filter intravenous delivery device with a rotating, ratcheted outlet connection that resists loosening while allowing controlled disconnection by holding a collar. The claim is structured around at least two different medications delivered through anti-reflux-valved inlet ports feeding pore filters, and a torque-tolerant rotating outlet port connected through a y-connector.
Dual anti-reflux inlet ports feeding different pore filters
A body section including a first inlet port including an anti-reflux valve and operably connected to a first smaller pore filter; a second inlet port including an anti-reflux valve and operably connected to a second larger pore filter; and at least one additional inlet port connected to the first filter.
Rotating outlet port with ratcheting collar limiting motion
A rotating outlet port including a collar which surrounds the outlet port, wherein the collar includes a ratcheting mechanism having a gear including teeth and spaces between the teeth, wherein the gear runs around an internal circumference of the collar, and a delivery protrusion with pawls being lock into the spaces between the teeth, and wherein the pawls are only rotatable within the spaces between teeth.
Y-connector joining rotating outlet to both filters
The rotating outlet port is joined to the first filter and the second filter by a y-connector.
Controlled intravenous line disengagement by holding collar
The rotating outlet port is configured to connect to an intravenous line such that the intravenous line is only allowed to disengage from the rotating outlet port by holding the collar when disconnecting the intravenous line.
Torque while delivering without loosening outlet connection
The device can be torqued while delivering the at least two different medications without loosening the rotating outlet port from the intravenous line.
Overall, the claim coverage centers on a multi-port IV delivery architecture combining anti-reflux-valved inlet ports to differently sized pore filters and a rotating outlet port whose collar ratcheting mechanism restricts collar movement and enables controlled disengagement. The rotating outlet supports torque during delivery without loosening the IV line connection.
Stated Advantages
Reduced infection risk, including healthcare-associated infections (HAI) and CLABSI (central line-associated bloodstream infections).
Reduced infusion of air, particulate, lipid, microorganisms, and endotoxins through filtering.
Minimal dead volume/dead space.
Reduced need for repeated disconnections and port scrubbing.
Self-priming.
Scrubbable inlet ports.
Allows device torque while delivering without loosening the rotating outlet port from the intravenous line.
Provides safety-related connection features including optional color-coded and locked/single-use inlet connections.
Documented Applications
Anesthesia induction example using multiple medications delivered simultaneously via multiple inlet ports, including propofol, cefazolin, lidocaine, rocuronium, midazolam, fentanyl, succinylcholine, ephedrine, and zofran.
