Abstract
A device connectable to a suction source for drawing off particulate matter from the air about a burning site comprises a flexible hose provided along an end segment with a plurality of spaced apertures, a fastener for detachably connecting the hose at an end opposite the apertured end segment to the suction source, and a coupling element for securing a free tip of the hose, at the free end of the apertured end segment, to the hose along a middle portion thereof to thereby form a loop including at least a portion of the apertured end segment.
Claims12
A method for use in surgery to reduce air borne particles carrying infectitious micro-organisms, comprising the steps of:
- providing a substantially flexible hose with at least one linear end segment and a plurality of apertures spaced along said end segment;
- detachably connecting said hose at an end opposite said segment to a suction source;
- forming at least a portion said hose into a substantially loop-shaped configuration;
- disposing said portion of said hose on a skin surface of a patient so that said loop-shaped configuration at least partially surrounds a surgical site on the patient;
- exerting a force on said portion of said hose to maintain said portion of said hose in said loop-shaped configuration during a surgical procedure;
- surgically removing organic tissues from said surgical site;
- generating air-borne particulate matter as a by-product of said step of removing;
- and
- during said step of removing, operating said suction source to apply suction to said hose and thereby draw off particulate matter from the air about said surgical site.
