Irrigation and aspiration devices and methods
Irrigation and/or aspiration devices and methods may be configured to aspirate and irrigate alone, sequentially, or concurrently. The devices and methods may provide a base with a removable head, and adapted for partial or complete separation of the irrigation and aspiration functions. The devices and methods can be configured to aspirate and/or irrigate the nasal and sinus cavities. The devices and methods may be manually and/or automatically controlled. The devices and methods may include removable, and/or replaceable, and/or refillable, and easily cleanable reservoirs for aspirant and irrigant. The device head and/or aspirant reservoir may comprise a diagnostic device, i.e., test device and/or container after use of the devices and methods.
1. A method for irrigating and/or aspirating a nostril, the method comprising:
providing a hand-held device comprising
an irrigation function, an aspiration function, and user controls,
the irrigation function comprising an irrigation force and an irrigation reservoir, the irrigation reservoir containing an irrigation fluid,
the aspiration function comprising an aspiration pressure and an aspiration reservoir, the aspiration reservoir adapted to capture aspirated fluid, the aspiration reservoir adapted to retain aspirated fluid in the aspiration reservoir and allow gas to pass out of the aspiration reservoir,
the user controls adapted to provide a control function for at least one of the irrigation function and the aspiration function,
and the irrigation function being operational with no interaction with the aspiration function, and the aspiration function being operational with no interaction with the irrigation function with the irrigation and aspiration functions being operational intermittently and/or simultaneously with one another,
initiating the irrigation force by user input to the irrigation function, the irrigation force acting upon the irrigation reservoir,
expelling irrigation fluid from the irrigation reservoir and into the nostril, initiating the aspiration pressure by user input to the aspiration function, and drawing fluid from the nostril and into the aspiration reservoir, and
passing the irrigation force and the aspiration pressure through an interface region.
2. The method according to claim 1 :
further including retaining aspirated fluid in the aspiration reservoir and allowing gas to pass out of the aspiration reservoir.
3. The method according to claim 1 :
further including simultaneously expelling irrigation fluid from the irrigation reservoir and into the orifice and drawing fluid from the nostril and into the aspiration reservoir.
4. The method according to claim 1 :
wherein the hand-held device comprises a head and a base, and the interface region comprises a seal between the head and the base, the seal adapted to allow the irrigation force exerted on the base to be transferred to the head, and
the seal adapted to allow the aspiration pressure from the base to draw gas out of the aspiration reservoir and into the base.
5. The method according to claim 1 :
further including holding the device in the user's hand.
6. The method of claim 1 , wherein the hand-held device comprises a housing, and wherein the irrigation function and the aspiration function occur at least partially in the housing.
7. The method of claim 6 , wherein the housing is sized and configured to be held in the user's hand.
8. The method of claim 6 , wherein the housing comprises a head and a base, and the interface region comprises a seal between the head and the base, the seal adapted to allow the irrigation force exerted on the base to be transferred to the head, and wherein the seal is adapted to allow the aspiration pressure from the base to draw gas out of the aspiration reservoir and into the base.
9. The method of claim 1 , wherein the irrigation force acts directly upon the irrigation reservoir.
10. The method of claim 1 , wherein the irrigation force acts indirectly upon the irrigation reservoir.
11. The method of claim 1 , wherein the aspirated fluid comprises mucus.
12. The method of claim 1 , wherein the hand-held device comprises a housing, and wherein the irrigation reservoir and the aspiration reservoir are within the housing.
13. The system according to claim 12 , further comprising removing and replacing at least one of the irrigation reservoir and the aspiration reservoir from the housing.
