Abstract
Abstract A device for aspirating body fluids comprising, a valve assembly having a first port to receive body fluids, a second port for passage of the body fluids from the valve assembly, and a passageway communicating between the first and second ports. The valve assembly has one-way valve means associated with the passageway to permit passage of body fluids from the first port to the second port and prevent passage of body fluids from the second port to the first port. The device has port means communicating with the passageway intermediate the valve means and first port, with the port means being normally closed to prevent contamination of the device, and being openable to permit passage of fluid through the port means to the first port.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
191 words
A device for aspirating body fluids, comprising: a valve assembly having a first port to receive body fluids, a second port for passage of the body fluids from the valve assembly, a passageway communicating between the first and second ports, one-way valve means associated with the passageway to permit passage of body fluids from the first port to the second port and prevent passage of body fluids from the second port to the first port, a third port, a second passageway communicating between the third port and the first passageway intermediate said valve means and second port, and second one-way valve means associated with the second passageway permitting passage of body fluids from the first passageway to the third port and preventing passage of fluids from the third port to the first passageway; port means communicating with the passageway intermediate said valve means and first port, said port means being normally closed to prevent contamination of the device, and being openable to permit passage of fluid through the port means to the first port; and pump means communicating with said second port for aspirating the body fluids through the valve assembly.
Claim 2
Independent Claim
191 words
A device for aspirating body fluids, comprising: a valve assembly having a first port to receive body fluids, a second port for passage of the body fluids from the valve assembly, a passageway communicating between the first and second ports, one-way valve means associated with the passageway to permit passage of body fluids from the first port to the second port and prevent passage of body fluids from the second port to the first port, a third port, a second passageway communicating between the third port and the first passageway intermediate said valve means and second port, and second one-way valve means associated with the second passageway permitting passage of body fluids from the first passageway to the third port and preventing passage of fluids from the third port to the first passageway; port means communicating with the passageway intermediate said valve means and first port, said port means being normally closed to prevent contamination of the device, and being openable to permit passage of fluid through the port means to the first port; and pump means communicating with said second port for aspirating the body fluids through the valve assembly.
