Abstract
A device comprising: (a) a housing; (b) one or more pumps located within the housing, the one or more pumps configured to create a negative pressure and move fluid; (c) one or more connectors located at least partially within in the housing; (d) internal fluid paths connecting the one or more pumps to the one or more connectors; (e) one or more reservoirs connected to the one or more connectors, the one or more reservoirs being configured to collect the fluid moved by the one or more pumps; and (f) a processor configured to: (i) calculate a total volume of fluid collected in the one or more reservoirs; and (ii) indicate that the one or more reservoirs are full; wherein the fluid moved is a fluid from a wound or incision.
Core Innovation
The portable post-surgical drainage system includes a housing with one or more pumps located within the housing. The one or more pumps create negative pressure and move fluid from a wound or incision through internal fluid paths to one or more reservoirs that collect the moved fluid.
The connectors are configured as a manifold with an exit in communication with the one or more pumps and two or more input connections that each include tubing receiving the fluid from the wound or the incision of a user. The system includes one-way valves to prevent backflow and pressure/vacuum loss, and reservoir designs that vent excess air using gas-permeable, liquid-impermeable membranes.
The system includes onboard processing to calculate a total volume of the fluid collected in the one or more reservoirs and to indicate that the one or more reservoirs are full. Wireless communication of device status and fluid characteristics is described, along with sensing-based detection features that relate operation to reservoir presence.
Claims Coverage
The independent claims identified are clm-00001, clm-00014, and clm-00020. Across these independent claims, the main inventive features are the portable negative-pressure wound or incision drainage device architecture with processor-based reservoir fill indication, a manifold connector with multiple tubing inputs, a prone or supine operating configuration, and a corresponding method.
Portable negative-pressure wound or incision fluid drainage device with in-housing pumps and reservoirs
A device comprising a housing, one or more pumps located within the housing configured to create negative pressure and move fluid from a wound or incision, one or more connectors located at least partially within the housing, internal fluid paths connecting the pumps to the connectors, one or more reservoirs connected to the connectors and configured to collect the fluid, and a processor configured to calculate a total volume of the fluid collected in the reservoirs and indicate that the reservoirs are full, where the connectors are a manifold with an exit in communication with the pumps and two or more input connections that each include tubing receiving the fluid.
Prone or supine negative-pressure operation with two pumps and discrete tubing
A device comprising a housing, one or more pumps located within the housing configured to create negative pressure and move fluid while a patient wearing the device is positioned in a prone position or a supine position, one or more connectors located at least partially within the housing, internal fluid paths connecting the pumps to the connectors, one or more reservoirs connected to the connectors and configured to collect the fluid moved by the pumps, and a processor in communication with the one or more pumps, wherein the pumps are two pumps and each of the two pumps is in communication with internal tubing and each of the two pumps includes discrete tubing.
Processor-controlled method for manifold negative-pressure drainage with reservoir volume calculation and full indication
A method comprising controlling one or more pumps of a device with a processor so that when the pumps are activated the pumps create negative pressure to move fluid from a wound or incision of a patient; moving the fluid through one or more connectors through internal fluid paths in communication with the pumps and into one or more reservoirs; calculating a total volume of fluids collected within one or more reservoirs; and indicating that the one or more reservoirs are full, wherein the connectors are a manifold with an exit in communication with the one or more pumps and two or more input connections that each include tubing receiving the fluid.
The independent claim set focuses on a portable negative-pressure drainage architecture that routes wound or incision fluid via internal fluid paths from in-housing pumps through manifold connectors with multiple tubing inputs into one or more reservoirs, together with processor-based calculation of total collected fluid volume and an indication that the reservoirs are full. A further independent claim specifies negative-pressure pump capability during patient prone or supine positioning and a two-pump configuration with discrete tubing, and the method claim recites processor-controlled operation corresponding to the device.
Stated Advantages
Calculates a total volume of the fluid collected in the one or more reservoirs.
Indicates that the one or more reservoirs are full.
Enables negative pressure operation while the patient wearing the device is positioned in a prone position or a supine position.
