Claims19
A portable, handheld device for irrigating with an irrigant and aspirating biological tissue and/or secretions comprising:
- a body;
- a first neck;
- a first head connected to the body, wherein the first head comprises a compliant outer surface configured to seal against a nostril, and wherein the first head is configured to be detached from the body;
- a first port in the first head;
- an irrigant reservoir in direct fluid communication with the first port, and wherein the first port is configured to deliver an irrigant to outside of the head;
- a first channel in the first head, wherein the first channel terminates at the first port;
- a second port configured to receive an aspirant from outside of the first head;
- a second channel in the first head, wherein the second channel terminates at the second port, and wherein the first channel is to one side of the second channel;
- an aspirant reservoir in direct fluid communication with the second port;
- and
- a fluid control system comprising a pump, wherein the fluid control system is configured to control an irrigation delivery pressure of the irrigant outside of the first head, and wherein the fluid control system is configured to control an aspiration pressure into the first head.
