Abstract
Abstract An apparatus for cleaning and drying articles of anesthesia and respiratory equipment, particularly corrugated tubing and breathing bags. The corrugated tubes are threaded onto vertically arranged, perforated pipes which have restricted flow passages at their ends. First cleaning liquid, then drying air, is supplied under pressure to the pipes for radially outward flow therefrom to impinge on the lumina of the tubes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
Apparatus for cleaning and drying lengths of corrugated tubing, hollow articles and other items constituting components of anesthesia and respiratory equipment comprising: a main chamber; a plurality of substantially vertically arranged pipes disposed within said main chamber, each said pipe being adapted to receive the lumen of a length of said corrugated tubing; each said pipe having one end in selective fluid communication with a source of cleaning liquid and a source of air; means for selectively supplying under pressure to said pipes cleaning liquid and air from said respective sources; and each said pipe further having longitudinally and circumferentially spaced ports for permitting said liquid and alternately said air present in said pipe under pressure to flow radially outwardly therefrom and into contact with said surrounding lumen.
Claim 2
Dependent Claim
128 words
Apparatus for cleaning and drying lengths of corrugated tubing, hollow articles and other items constituting components of anesthesia and respiratory equipment comprising: a main chamber; a plurality of substantially vertically arranged pipes disposed within said main chamber, each said pipe being adapted to receive the lumen of a length of said corrugated tubing; each said pipe having one end in selective fluid communication with a source of cleaning liquid and a source of air; means for selectively supplying under pressure to said pipes cleaning liquid and air from said respective sources; and each said pipe further having longitudinally and circumferentially spaced ports for permitting said liquid and alternately said air present in said pipe under pressure to flow radially outwardly therefrom and into contact with said surrounding lumen.
Claim 3
Dependent Claim
19 words
Apparatus as recited in claim 1 wherein: said ports in adjacent longitudinal rows along said pipe are transversely staggered.
Claim 4
Dependent Claim
51 words
Apparatus as recited in claim 1 wherein said plurality of vertically arranged pipes includes: at least one pair of axially aligned pipes, one suspended from the top of said main chamber and the other supported by the floor of said main chamber, having their adjacent ends spaced apart from one another.
Claim 5
Dependent Claim
49 words
Apparatus as recited in claim 1, which apparatus further comprises: means disposed within said main chamber for spraying cleaning liquid onto the exterior surfaces of corrugated tubing surrounding said pipes; and means for directing air into contact with said exterior surfaces after said main chamber spray means is deactivated.
Claim 6
Dependent Claim
107 words
Apparatus as recited in claim 1, which apparatus further comprises: an auxiliary chamber; a plurality of upstanding pipes disposed within said auxiliary chamber, each said upstanding pipe being adapted to extend into the interior of a hollow flexible article and support it; each said upstanding pipe having its lower end in selective fluid communication with said pressurized sources of cleaning liquid and air, respectively; and each said upstanding pipe further having longitudinally and circumferentially spaced ports for permitting said liquid and alternately said air, supplied under pressure to said upstanding pipe, to flow radially outwardly therefrom and into contact with the interior surfaces of said hollow article.
Claim 7
Dependent Claim
52 words
Apparatus as recited in claim 5, which apparatus further comprises: means disposed within said auxiliary chamber for spraying cleaning liquid onto the exterior surfaces of said hollow article disposed therein; and means for directing air into contact with said exterior surfaces of said hollow article after said auxiliary spray means is deactivated.
Claim 8
Dependent Claim
34 words
Apparatus as recited in claim 5, which apparatus further comprises: means within said auxiliary chamber for supporting sundry components of anesthesia and respiratory equipment for exposure to said auxiliary spray means and said air.
