Abstract
Method and device for scavenging tainted escape gas at a location proximate the patient's mouth (24) before that gas diffuses into, or otherwise reaches the personal breathing space (32, 35) of attending health care providers (38, 39). The scavenging device (50) includes, but is not limited to a suction arrangement (52) suspendable from a patient's nasal mask (40) used for administering gaseous analgesia or anesthetic such as nitrous oxide to the patient (20). A suction inlet (54) is positionable proximate the patient's mouth (24) and an exhaust outlet (56) is provided that is interconnectable with a vacuum source (46).
Claims36
A device (50) for scavenging tainted escape gas (26) released from the mouth of a patient (20) receiving a gaseous analgesia or anesthetic into the personal breathing space (32, 35) of a health care provider (38, 29) performing a medical procedure on the patient (20), said device (50) comprising:
- a suction arrangement (52) suspendable from a patient's nasal mask (40) used for administering gaseous analgesia or anesthetic to a patient;
- said suction arrangement (52) having a suction inlet (54) sufficiently positionable proximate the patient's mouth (24) so as to scavenge tainted escape gas released from the patient's mouth into the personal breathing space (32, 35) of a health care provider (38, 29) when the health care provider is positioned adjacent the patient (20) and an adjustable interconnection (58) mounting said suction arrangement (52) upon the patient's nasal mask (40), said adjustable interconnection (58) enabling variable positioning of said suction inlet (54) relative to the patient's mouth (24) and said suction arrangement (52) and said mounting (58) together establishing a cantilever suspension (60) of said suction inlet (54) below the nose of the patient (20);
- and
- said suction arrangement (52) further comprising an exhaust outlet (56) interconnectable with a vacuum source (46) for instituting tainted escape gas scavenging proximate the patient's face for the benefit of the health care provider by limiting exposure of the health care provider to tainted escape gas (26).
A method for scavenging tainted escape gas (26) released from the mouth of a patient (20) receiving a gaseous analgesia or anesthetic into the personal breathing space (32, 35) of a health care provider (38, 39) performing a medical procedure on the patient (20), said method comprising:
- suspending a suction arrangement (52) from a patient's nasal mask (40) used for administering gaseous analgesia or anesthetic to the patient;
- positioning a suction inlet (54) of said suction arrangement (52) sufficiently proximate the patient's mouth (24) so as to scavenge tainted escape gas released from the patient's mouth into the personal breathing space (32, 35) of a health care provider (38, 39) when the health care provider is positioned adjacent to the patient and adjustably mounting said suction arrangement (52) upon the patient's nasal mask (40) in cantilever suspension (60), said adjustable interconnection (58) enabling variable positioning of said suction inlet (54) relative to the patient's mouth (24);
- and
- interconnecting an exhaust outlet (56) of said suction arrangement (52) to a vacuum source (46) and instituting tainted escape gas scavenging proximate the patient's face thereby benefiting the health care provider by limiting exposure of the health care provider to tainted escape gas.
A device (50) for scavenging tainted escape gas (26) released from the mouth of a patient (20) receiving a gaseous analgesia or anesthetic into the personal breathing space (32, 35) of a health care provider (38, 29) performing a medical procedure on the patient (20), said device (50) comprising:
- a suction arrangement (52) comprising a suction means configured for being suspended from a patient's nasal mask (40) used for administering gaseous analgesia or anesthetic to a patient;
- said suction means having a suction inlet (54) configured to be positioned sufficiently proximate the patient's mouth (24) so as to scavenge tainted escape gas released from the patient's mouth into the personal breathing space (32, 35) of a health care provider (38, 29) when the health care provider is positioned adjacent the patient (20) and an adjustable interconnection (58) mounting said suction arrangement (52) upon the patient's nasal mask (40), said adjustable interconnection (58) enabling variable positioning of said suction inlet (54) relative to the patient's mouth (24) and said suction arrangement (52) and said mounting (58) together establishing a cantilever suspension (60) of said suction inlet (54) below the nose of the patient (20);
- and said suction means further comprising an exhaust outlet (56) configured to be interconnected with a vacuum source (46) for instituting tainted escape gas scavenging proximate the patient's face for the benefit of the health care provider by limiting exposure of the health care provider to tainted escape gas (26).
