Filed:

Aug 10, 2006

Appl. No.:

11/426348

Inventors:

Frederick Trombley - Gibsonia PA, US
Kevin Cowan - Allison Park PA, US
Kraig McEwen - Mars PA, US
Joseph Havrilla - Pittsburgh PA, US

Assignee:

MEDRAD, INC. - Indianola PA

International Classification:

A61M 25/00

US Classification:

604523000, 604187000

Abstract:

A medical connector includes a body defining a lumen for fluid flow through the medical connector. The medical connector includes a luer member and an annular member disposed about the luer member. The annular member includes internal and/or external engagement structures. The medical connector may be provided on the outlet of a syringe or on a catheter. A fluid path is disclosed including a first section and a second section. The first and second sections may each include a medical connector to provide a removable connection with a syringe and a catheter, respectively. The medical connector may provide a removable connection between the first and second sections. A fluid delivery system is disclosed including an injector, a syringe operatively associated with the injector, and a fluid path connecting the syringe and a source of injection. The medical connector may provide a removable connection between the syringe and fluid path.

International Classification:

A61F 7/00
A61M 1/36
A61M 1/14
F28D 7/16

Abstract:

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters, A controller is operative!}′ coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.
