Abstract
A device for irrigating a body cavity is disclosed. The device comprises a first pump and a second pump being operatively linked via a manually-operated actuator member. The actuator member has at least a mode in which the actuator member activates the first pump to eject an initial volume of fluid out of the device, and a mode in which the actuator member activates the second pump to eject fluid out of the device and simultaneously activates the first pump to withdraw fluid into the device.
Core Innovation
The disclosed invention relates to a hand-held irrigating-evacuating device for irrigating a body cavity using a first pump and a second pump operatively linked via a manually-operated actuator member having a handle. The actuator member provides at least one mode that activates only the first pump and another mode that simultaneously activates both the first and second pumps, and in the mode that activates only the first pump, the first pump ejects an initial volume of fluid out of the device.
In the mode that simultaneously activates both pumps, the second pump ejects fluid out of the device while the first pump withdraws fluid into the device, so that irrigation and evacuation occur together. The device connects to the body cavity via a tube having a first line in fluid communication with the first pump and a separate second line in fluid communication with the second pump.
The invention is also described with linked dual pump actuation, including examples of dual syringe mechanisms, and in some embodiments a linear relationship between first and second volumetric flow rates. The disclosure further includes a kit with an intubation device and defines lumen and cuff-related structures, including suction lumens above an inflatable cuff and an irrigation lumen above the cuff, with optional pressure measurement.
Claims Coverage
The partial content provides four independent claims. Across these claims, the inventive coverage centers on a manually-operated actuator member driving operatively linked first and second pumps in selectable modes, including an initial delivery-only mode and a subsequent simultaneous deliver-and-withdraw mode, with additional sequencing and line/tube connectivity and, for trachea-related claims, procedural context limitations.
Selectably actuated first and second pumps for sequential delivery and simultaneous withdraw/deliver
A device for irrigating a body cavity with a first pump and a second pump operatively linked via a manually-operated actuator member having a handle, wherein the actuator member has at least a mode that activates only the first pump and a mode that simultaneously activates both the first and second pumps, the first pump ejects an initial volume of fluid out of the device in the first mode, and in the simultaneous mode the second pump ejects fluid out of the device and the first pump withdraws fluid into the device.
Handle-driven first delivery without withdrawal followed by simultaneous withdraw/deliver using separate fluid lines
A method of irrigating a body cavity with fluid including moving a handle to manually deliver a first volume without withdrawing, subsequently moving the handle to manually deliver a second volume and simultaneously withdraw at least the second volume, wherein the device has a first pump and a second pump operatively linked via the manually-operated actuator member, and wherein the device is connected to the body cavity via a tube having a first line in fluid communication with the first pump and a separate second line in fluid communication with the second pump.
Three-stage sequence: initial delivery without withdrawal, then simultaneous withdraw/deliver, then withdrawal-only
A method of irrigating a body cavity with fluid comprising moving a handle to manually deliver a first volume without withdrawing, subsequently moving the handle to manually deliver a second volume while simultaneously withdrawing at least the second volume, and subsequently withdrawing fluid from the body cavity without delivering fluid into the body cavity.
Trachea-specific irrigation with two-stage delivery and simultaneous withdraw/deliver
A method of irrigating a trachea of a subject with fluid comprising moving a handle to manually deliver a first volume to the trachea without withdrawing, and subsequently moving the handle to manually deliver a second volume and simultaneously withdraw at least the second volume from the trachea.
The independent claims collectively cover manually actuated control of operatively linked pumps to enable an initial delivery-only phase and a subsequent simultaneous deliver-and-withdraw phase, with additional sequencing in one independent claim to include a final withdrawal-only phase and with trachea-specific implementations in another independent claim.
