Abstract
An irrigation and aspiration system is disclosed. The system can be configured to aspirate and irrigate alone, sequentially or concurrently. The system can be configured to aspirate and irrigate the nasal cavity. The system can be manually controlled. The system can have removable and easily cleanable reservoirs for aspirant and irrigant.
Claims26
A method for a user to irrigate and aspirate the nose comprising:
- holding an entire device in a hand of the user, wherein the device is portable;
- aspirating inside the nose with the device without irrigating inside of the nose with the nose:
- simultaneously irrigating at an irrigation pressure inside the nose with the device and aspirating at an aspiration pressure inside the nose with the device, wherein the device comprises a body and a head connected to the body, an irrigant reservoir, an aspirant reservoir, a first port in the head in fluid communication with the irrigant reservoir, and a second port in the head in direct fluid communication with the aspirant reservoir;
- controlling with a multi-state control between the aspiration without irrigation and the simultaneously irrigating and aspirating;
- and
- wherein irrigating comprises delivering an irrigant from the irrigant reservoir, through the first port and into the natural body orifice with an irrigation pressure, and
- wherein aspirating comprises receiving an aspirant from the natural body orifice, through the second port and directly into the aspirant reservoir with an aspiration pressure.

A method for a user to irrigate and aspirate the nose comprising:
- holding an entire device in a hand of the user, wherein the device is portable;
- aspirating inside the nose with the device, wherein the aspirating is performed to clear fluid and/or debris from the nose not needing any irrigation, wherein the device comprises a body and a head connected to the body, an irrigant reservoir, an aspirant reservoir, a first port in the head in fluid communication with the irrigant reservoir, and a second port in the head in direct fluid communication with the aspirant reservoir;
- sequentially aspirating inside the nose with the device and then concurrently aspirating inside the nose with the device and irrigating inside the nose with the device;
- simultaneously irrigating at an irrigation pressure inside the nose with the device and aspirating at an aspiration pressure inside the nose with the device;
- controlling with a multi-state control between the aspirating, the sequential aspirating and then concurrent aspirating and irrigating, and the simultaneously irrigating and aspirating;
- and
- wherein irrigating comprises delivering an irrigant from the irrigant reservoir, through the first port and into the natural body orifice with an irrigation pressure, and
- wherein aspirating comprises receiving an aspirant from the natural body orifice, through the second port and directly into the aspirant reservoir with an aspiration pressure.
5 more elements
A method for a user to irrigate and aspirate the nose comprising:
- holding an entire device in a hand of the riser, wherein the device is portable;
- controlling with a multi-state control between at least an aspirating setting, and a simultaneous irrigating and aspirating setting;
- wherein when the control is set to the simultaneously irrigating and aspirating setting, the device simultaneously irrigates at an irrigation pressure inside the nose and aspirates at an aspiration pressure inside the nose, wherein the device comprises a body and a head connected to the body, an irrigant reservoir, an aspirant reservoir, a first port in the head in fluid communication with the irrigant reservoir, and a second port in the head in direct fluid communication with the aspirant reservoir;
- wherein when the control is set to the aspirating, the device aspirates inside the nose;
- wherein when the control is set to the aspirating setting, the device aspirates inside the nose with the device, and the device clears fluid and/or debris from the nose;
- wherein irrigating comprises delivering an irrigant from the irrigant reservoir through the first port and into the natural body orifice with an irrigation pressure, and liquefying debris in the nose, and
- wherein aspirating comprises removing the debris, wherein the removing of the debris comprises receiving an aspirant from the natural body orifice, through the second port and directly into the aspirant reservoir with an aspiration pressure.
