Abstract
Abstract A fluid collection apparatus is provided for controlling fluid communication between a vacuum source and first and second vacuum lines of a surgical device such as a core sampling biopsy device. The fluid collection apparatus comprises first and second fluid lines adapted for detachably connecting to, and in fluid communication with, the first and second vacuum lines, respectively, of the surgical device. The fluid collection apparatus further comprises first and second valves in fluid communication with first and second fluid lines, respectively. Each of first and second valves has an open position and a closed position. The fluid collection apparatus further comprises an air vent selectively communicating with first and second vacuum lines, and a valve frame for fixing first and second valves relative to each other, where the valve frame has a latching means for detachably connecting the valve frame to the surgical device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
279 words
A fluid collection apparatus for controlling fluid communication between a vacuum source and first and second vacuum lines of a surgical device, said fluid collection apparatus comprising: a. a first fluid line adapted for detachably connecting to, and in fluid communication with, said first vacuum line; b. a second fluid line adapted for detachably connecting to, and in fluid communication with, said second vacuum line; c. a first valve having a first longitudinal axis, said first valve in fluid communication with said first fluid line, wherein said first valve has an open position and a closed position; d. a second valve having a second longitudinal axis, said second valve in fluid communication with said second fluid line, wherein said second valve has an open position and a closed position; e. an air vent selectively communicating with said first and second fluid lines, and when said first valve is in said closed position and said first and second fluid lines are connected to said first and second vacuum lines, fluid communication is blocked between said vacuum source and said first vacuum line, and said air vent is in fluid communication with said first vacuum line, and when said second valve is in said closed position and said first and second fluid lines are connected to said first and second vacuum lines, fluid communication is blocked between said vacuum source and said second vacuum line, and said air vent is in fluid communication with said second vacuum line; and f. a valve frame fixing said first and second valves relative to each other, said valve frame having a latching means adapted for detachably connecting said valve frame to said surgical device.
Claim 2
Dependent Claim
279 words
A fluid collection apparatus for controlling fluid communication between a vacuum source and first and second vacuum lines of a surgical device, said fluid collection apparatus comprising: a. a first fluid line adapted for detachably connecting to, and in fluid communication with, said first vacuum line; b. a second fluid line adapted for detachably connecting to, and in fluid communication with, said second vacuum line; c. a first valve having a first longitudinal axis, said first valve in fluid communication with said first fluid line, wherein said first valve has an open position and a closed position; d. a second valve having a second longitudinal axis, said second valve in fluid communication with said second fluid line, wherein said second valve has an open position and a closed position; e. an air vent selectively communicating with said first and second fluid lines, and when said first valve is in said closed position and said first and second fluid lines are connected to said first and second vacuum lines, fluid communication is blocked between said vacuum source and said first vacuum line, and said air vent is in fluid communication with said first vacuum line, and when said second valve is in said closed position and said first and second fluid lines are connected to said first and second vacuum lines, fluid communication is blocked between said vacuum source and said second vacuum line, and said air vent is in fluid communication with said second vacuum line; and f. a valve frame fixing said first and second valves relative to each other, said valve frame having a latching means adapted for detachably connecting said valve frame to said surgical device.
Claim 3
Dependent Claim
90 words
The fluid collection apparatus of claim 1 further comprising a first engagement means attached to said first valve and adapted for detachably and operationally connecting said first valve to an electrically operated first actuator of said surgical device for actuating said first valve between said open and closed positions, and a second engagement means attached to said second valve and adapted for detachably and operationally connecting said second valve to an electrically operated second actuator of said surgical device for actuating said second valve between said open and closed positions.
Claim 4
Dependent Claim
65 words
The fluid collection apparatus of claim 2 wherein said valve frame fixes said first and second valves so that said first longitudinal axis of said first valve is parallel to said second longitudinal axis of said second valve, and when said valve frame is detachably connected to said surgical device, said first and second valves are simultaneously connected operationally to said first and second actuators.
Claim 5
Dependent Claim
23 words
The fluid collection apparatus of claim 3 wherein said first actuator is a first solenoid and said second actuator is a second solenoid.
Claim 6
Dependent Claim
21 words
The fluid collection apparatus of claim 4 wherein said first solenoid and said second solenoid are controlled independently of each other.
Claim 7
Dependent Claim
25 words
The fluid collection apparatus of claim 5 wherein said first valve includes a first manual control and said second valve includes a second manual control.
Claim 8
Dependent Claim
23 words
The fluid collection apparatus of claim 1 further comprising an injection port in at least one of said first and second fluid lines.
Claim 9
Dependent Claim
25 words
The fluid collection apparatus of claim 1 wherein said first valve is a first rotary valve and said second valve is a second rotary valve.
Claim 10
Dependent Claim
14 words
The fluid collection apparatus of claim 1 wherein said air vent includes a filter.
Claim 11
Dependent Claim
29 words
The fluid collection apparatus of claim 1 wherein said valve frame includes a handle for holding said valve frame while detachably connecting said valve frame to said surgical device.
