Abstract
A fluid separation and collection canister operable in-line between a sub-atmospheric pump and a source of mixed fluid-gas flow. In one application, the present invention finds particular use in a healthcare environment to assist in the removal of fluids from a patient with internal or external injuries. The enclosed collection canister is made up of two case half shells separable at mid-line overlapping joint. The upper case half shell incorporates a suction port with a sub-micron gas filter, a pass-through port, and an upper fluid extraction port. The lower case half shell incorporates an inlet port with a one-way fluid valve, a lower pass-through port, and a lower fluid extraction port. The pass-through ports are used to carry a pressure monitoring lumen to the source of the mixed fluid-gas flow.
Core Innovation
A fluid separation and collection canister is provided for inline operation between a sub-atmospheric pump and a source of mixed fluid-gas flow. The canister includes an upper case half shell with a suction port having a sub-micron gas filter, an upper pass-through port, and an upper fluid extraction port, and a lower case half shell attached to and separable from the upper case half shell at a mid-line overlapping joint. The lower case half shell includes an inlet port with a one-way fluid valve, a lower pass-through port, and a lower fluid extraction port.
When the lower case half shell is attached to the upper case half shell at the mid-line overlapping joint, the attachment defines a sealed canister enclosure flow accessible through the suction port, the inlet port, the pass-through ports, and the fluid extraction ports. The one-way fluid valve provides one-way fluid control associated with the inlet port, and the sub-micron gas filter is associated with the suction port to support gas separation with the canister operating in-line with the sub-atmospheric pump.
An added aspect in the described embodiments is a pass-through structure used with pressure monitoring, including pressure monitoring in an applied suction pathway and in an isolated reference pathway. The pressure monitoring is supported by the upper and lower pass-through ports and a sealed canister enclosure configured for access through suction and pass-through related ports.
Claims Coverage
Two independent claims are identified, covering an in-line fluid separation and collection canister with a sealed, separable upper and lower shell and multiple ports including a sub-micron gas filter, and a corresponding fluid separation and collection system that simultaneously monitors pressures in an applied suction pathway and a segregated reference pathway using first and second pressure transducers.
Inline fluid separation and collection canister with sealed separable upper and lower shells
A fluid separation and collection canister operable in-line between a sub-atmospheric pump and a source of mixed fluid-gas flow, comprising an upper case half shell with a suction port with a sub-micron gas filter, an upper pass-through port, and an upper fluid extraction port; and a lower case half shell attached to and separable from the upper case half shell at a mid-line overlapping joint, the lower case half shell comprising an inlet port with a one-way fluid valve, a lower pass-through port, and a lower fluid extraction port; wherein attachment at the mid-line overlapping joint defines a sealed canister enclosure flow accessible through the suction port, the inlet port, the pass-through ports, and the fluid extraction ports.
System for simultaneous dual-path pressure monitoring with first and second transducers
A fluid separation and collection system for connection to a source of mixed fluid-gas flow, comprising a sub-atmospheric pump; a collection canister connected in-line between the sub-atmospheric pump and the source of mixed fluid-gas flow; the collection canister comprising a shell enclosure having a suction port and an inlet port; upper and lower pass-through ports connecting a segregated pass-through conduit; and upper and lower fluid-gas extraction ports; a first pressure transducer for monitoring pressure in an applied suction pathway through the collection canister, the first pressure transducer in flow communication with the suction port; and a second pressure transducer for monitoring pressure in a reference pathway in the segregated pass-through conduit, the second pressure transducer in flow communication with upper pass-through port; wherein the system simultaneously monitors pressures within the canister and at the source of mixed fluid-gas flow.
Claim coverage centers on an in-line separable canister architecture defining a sealed canister enclosure with a sub-micron gas filter suction port and one-way inlet valve, and on a system architecture that uses a first and second pressure transducer to simultaneously monitor pressure in an applied suction pathway and a segregated reference pathway.
