Abstract
Abstract A container (400) for the collection of fluids in a vacuum system includes upper and lower chambers (402, 404). Fluids are admitted to the upper chamber (402) to form a vortex and separate fluid and debris from air. The fluids then pass to the lower chamber (404) through a filter (412). A discharge tube (428) is connected to the lower chamber (404) to allow the accumulated fluids to be pumped from the container (400). The bottom of the lower chamber (404) includes a recess (430) that forms a platen for a roller pump, and a discharge tube (428) is located adjacent the platen whereby rollers (426) engage the tube (428) and platen upon installation of the chamber (400) on a base. A second port (418) is provided to the upper chamber (402) for admission of a second fluid such as an anticoagulant.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
98 words
Apparatus for collection of fluids comprising a chamber formed by an upper element and a lower element, wherein said upper element comprises an upper chamber formed between an outer wall and an inner wall and said inner wall forms an inner cavity in communication with said lower element, a vacuum port connected to said inner cavity for conducting air from said chamber and reducing the pressure in said chamber, a fluid inlet for admitting a first fluid into said upper chamber in response to reduced pressure in said chamber, and means for discharging said fluids from said chamber.
Claim 2
Dependent Claim
98 words
Apparatus for collection of fluids comprising a chamber formed by an upper element and a lower element, wherein said upper element comprises an upper chamber formed between an outer wall and an inner wall and said inner wall forms an inner cavity in communication with said lower element, a vacuum port connected to said inner cavity for conducting air from said chamber and reducing the pressure in said chamber, a fluid inlet for admitting a first fluid into said upper chamber in response to reduced pressure in said chamber, and means for discharging said fluids from said chamber.
Claim 3
Dependent Claim
81 words
Apparatus according to claim 1 further comprising a second port for admitting a second fluid to said upper chamber in response to said reduced pressure for mixing with said first fluid in said upper chamber, means attached to said second port for controlling the flow of said second fluid into said upper chamber such that the amount of said second fluid drawn into said chamber is in approximately fixed proportion to the amount of said first fluid drawn into said chamber.
Claim 4
Dependent Claim
17 words
Apparatus according to claim 2 wherein said means attached to said second port is a porous disk.
Claim 5
Dependent Claim
29 words
Apparatus according to claim 1 wherein said upper chamber receives said first fluid from the exterior of said chamber and forms therein a vortex flow in said first fluid.
Claim 6
Dependent Claim
19 words
Apparatus according to claim 4 wherein said means for discharging comprises a discharge port connected to said lower element.
Claim 7
Dependent Claim
35 words
Apparatus according to claim 5 wherein said means for discharging further comprises a flexible outlet line connected to said discharge port and a roller-pump platen formed in said lower element adjacent said flexible outlet line.
Claim 8
Dependent Claim
18 words
Apparatus according to claim 6 wherein said platen is formed in a bottom surface of said lower element.
Claim 9
Dependent Claim
26 words
Apparatus according to claim 1 wherein said fluid inlet is positioned with respect to said upper element to form a vortex flow in said first fluid.
Claim 10
Dependent Claim
94 words
Apparatus for collection and discharge of fluids comprising a chamber for receiving said fluids, a fluid inlet for admitting said fluids to said chamber, a discharge port for allowing said fluids to flow out of said chamber, a flexible outlet line attached to said discharge port for carrying discharged fluids, and a recess in said chamber adjacent said flexible outlet line, said recess forming a platen for engaging said flexible outlet line when said flexible outlet line is pushed into engagement with said recess by rollers to pump said fluids through said discharge port.
Claim 11
Dependent Claim
94 words
Apparatus for collection and discharge of fluids comprising a chamber for receiving said fluids, a fluid inlet for admitting said fluids to said chamber, a discharge port for allowing said fluids to flow out of said chamber, a flexible outlet line attached to said discharge port for carrying discharged fluids, and a recess in said chamber adjacent said flexible outlet line, said recess forming a platen for engaging said flexible outlet line when said flexible outlet line is pushed into engagement with said recess by rollers to pump said fluids through said discharge port.
Claim 12
Dependent Claim
15 words
Apparatus according to claim 9 wherein said recess is in the bottom of said chamber.
Claim 13
Dependent Claim
49 words
Apparatus according to claim 9 wherein said chamber comprises an upper element and a lower element in fluid communication with said upper element and said fluid inlet is tangentially located in said upper element to form a vortex flow in said fluids that are admitted to said upper element.
Claim 14
Dependent Claim
11 words
Apparatus according to claim 11 wherein said upper element is cylindrical.
Claim 15
Dependent Claim
16 words
Apparatus according to claim 11 further comprising a vacuum port in communication with said lower element.
