Abstract
Abstract ABSTRACT OF THE DISCLOSURE A collection system having a vacuum source in flow communi-cation with a closed fluid collection vessel which is in flow communication with an inlet conduit disposed to apply the vacuum to non-gaseous fluids. The non-gaseous fluids to be collected are ingested through the inlet con-duit through an inlet port to the closed collection vessel where they are retained. The collection vessel is kept at a negative gauge pressure through an outlet port connecting the collection vessel to the vacuum source. A fixed restriction is provided at one point in the vacuum line to conserve energy by reducing the flow of gas through the system to the vacuum source.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A system for collecting non-gaseous fluids comprising: a vacuum source, a closed fluid collection vessel having an inlet port and an outlet port, an inlet conduit having its discharge end in flow communication with said inlet port, a vacuum conduit connecting said vacuum source and said outlet port, said vacuum conduit having a diameter at least equal to the diameter of said inlet conduit, said vacuum conduit and said outlet port forming a vacuum line, and a fixed gas flow restric-tion means positioned across the interior of said section of said vacuum line for reducing at one point the cross section of said vacuum line available for fluid flow.
Claim 2
Independent Claim
109 words
A system for collecting non-gaseous fluids comprising: a vacuum source, a closed fluid collection vessel having an inlet port and an outlet port, an inlet conduit having its discharge end in flow communication with said inlet port, a vacuum conduit connecting said vacuum source and said outlet port, said vacuum conduit having a diameter at least equal to the diameter of said inlet conduit, said vacuum conduit and said outlet port forming a vacuum line, and a fixed gas flow restric-tion means positioned across the interior of said section of said vacuum line for reducing at one point the cross section of said vacuum line available for fluid flow.
Claim 3
Dependent Claim
24 words
The system of claim 1 where said restriction means has a diameter of from 1% to 75% of the diameter of said vacuum conduit.
Claim 4
Dependent Claim
12 words
The system of claim 2 where said restriction means is an orifice.
Claim 5
Dependent Claim
24 words
The system of claim 3 in which said orifice has a diameter of from 5% to 25% of the diameter of said vacuum con-duit.
Claim 6
Dependent Claim
14 words
The system of claim 2 where said restriction means consists of a porous member.
Claim 7
Dependent Claim
29 words
The system of claim 2 where said vacuum line in-cludes a flexible portion, and said restriction means consists of a clamp attached to the exterior of said flexible portion.
Claim 8
Dependent Claim
36 words
The system of claim 1 where said collection vessel and said inlet conduit have a volume no less than the volume of that portion of said vacuum line between said flow restric-tion and said vacuum source.
Claim 9
Dependent Claim
37 words
The system of claim 1 where said restriction is a control means including two orifices, positioned inside said vacuum line, and means positioned outside said vacuum line for selecting which orifice is placed across said vacuum line.
Claim 10
Dependent Claim
43 words
The system of claim 8 where said control means has a first orifice of a diameter about equal to that of said vacuum conduit and a second orifice of a diameter of from 1% to 75% of the diameter of said vacuum conduit.
Claim 11
Independent Claim
109 words
A system of collecting body fluids comprising: a vacuum source, a closed fluid collection vessel having an inlet port and an outlet port, an inlet conduit leading to said body fluids and having its discharge end in flow communication with said inlet port, a vacuum conduit connecting said vacuum source and said outlet port, said vacuum conduit and said out-let port forming a vacuum line, and positioned at one point along the vacuum line, a gas flow restriction means fixed across the interior of said vacuum line, said flow restriction means having a diameter available for flow of from 1% to 75% of the diameter of said vacuum conduit.
Claim 12
Independent Claim
109 words
A system of collecting body fluids comprising: a vacuum source, a closed fluid collection vessel having an inlet port and an outlet port, an inlet conduit leading to said body fluids and having its discharge end in flow communication with said inlet port, a vacuum conduit connecting said vacuum source and said outlet port, said vacuum conduit and said out-let port forming a vacuum line, and positioned at one point along the vacuum line, a gas flow restriction means fixed across the interior of said vacuum line, said flow restriction means having a diameter available for flow of from 1% to 75% of the diameter of said vacuum conduit.
Claim 13
Dependent Claim
14 words
The system of claim 10 where said flow restriction means is an orifice member.
Claim 14
Dependent Claim
14 words
The system of claim 10 where said flow restriction means is a porous member.
Claim 15
Dependent Claim
38 words
The system of claim 10 where said flow restriction means is a control means including a plurality of orifice members, and means positioned outside said vacuum line for selecting which orifice member is placed across said vacuum line.
