7006005, Feb 28, 2006

Filed:

Feb 26, 1998

Appl. No.:

09/030989

Inventors:

Richard A. Nazarian - Golden Valley MN, US
Dirk R. Smith - St. Paul MN, US
James R. Watts - Woodbury MN, US
Timothy J. Kriewall - Castle Rock CO, US
Richard A. Griewski - Canton Township MI, US

Assignee:

Terumo Cardiovascular Systems - Ann Arbor MI

International Classification:

H04Q 1/00

US Classification:

34082506, 439638, 604 27

Abstract:

An adapter pod for use in a medical perfusion system having a data communications network with a plurality of connection points each having a substantially identical network connector. The adapter pod includes a housing and a common connector associated with the housing which is adapted to be connected to one of the network connectors and which has a connector configuration. A device connector is also associated with the housing, is adapted to be connected to a perfusion device, and has a configuration different than the connector configuration of the common connector. A controller is disposed within the housing and is adapted to generate messages in the form of digital data packets.

International Classification:

A61M 100

US Classification:

600 17

Abstract:

A medical perfusion system for use in connection with the medical treatment of a patient is provided with a first type of perfusion device in the form of a blood pump adapted to pump blood through a fluid conduit connected to the patient, a second type of perfusion device in the form of a sensor adapted to sense a condition relating to the pumping of blood through the fluid conduit and to generate a sensing signal relating to the condition, and a data communications network for operatively interconnecting the perfusion devices. The perfusion system also includes means for transmitting messages in the form of digital data packets among the perfusion devices over the data communications network and a controller operatively coupled to the perfusion devices via the data communications network, the controller having an input device for accepting pump control commands relating to the blood pump from an operator.

F04B 4106

US Classification:

417 4

Abstract:

A medical perfusion system for use in connection with the medical treatment of a patient is provided with a first type of perfusion device in the form of a blood pump adapted to pump blood through a fluid conduit connected to the patient and a second type of perfusion device in the form of a sensing device adapted to sense a condition and generate a sensing signal relating to the condition. The perfusion system also includes an electrical power network having an electrical power line, means for selectively connecting the perfusion devices to the electrical power network, and a controller with an input device for accepting control commands from an operator. The perfusion system could also include a control device, such as a pump, a plurality of sensing devices, and means for specifying the sensing device that the control device should be accept feedback from.

Assignee:

International Classification:

A61M 100

US Classification:

604 30

Abstract:

An irrigation system for use in endoscopic procedures for maintaining and controlling flow of irrigation fluid to an internal body irrigation site. The system includes a tubing set comprising inflow and outflow lines and a cassette, and an fluid control module comprising a race and a pumping mechanism that squeezes the inflow line of the tubing set against the race to pump fluid to the irrigation site. The cassette includes a through opening exposing a portion of the inflow line to the race and pumping mechanism so that the cassette merely holds the inflow line in alignment with the pumping mechanism but is not required to resist the compressive force of the pumping mechanism. The cassette may include a second through opening exposing a portion of the outflow line to a valve mechanism to regulate pressure independently of the pump mechanism, and rib-or-groove alignment mechanism to align the inflow line with the pumping mechanism and the outflow line with the valve mechanism.
