Abstract: A connecting arrangement and a process for its production, wherein the connecting arrangement consists of a first and a second separate part which are constituents of a medical system, in which at least one section of a surface made of a first plastic material on the first separate part and at least one section of a surface made of a second plastic material on the second separate part in a contact area which comprises at least sections of the surfaces of the first and second parts which are touching, form a firm and well-sealed connection with each other, this being obtainable by bringing the surfaces on the first and second separate parts to be connected to each other into contact with subsequent heat--treatment of the surfaces of the separate parts which are in contact, followed by cooling, characterised in that the first plastic material contains at least one polymer which is dimensionally stable at the temperature of heat-treatment, whereas the second plastic material contains at least one polymer which is no longer dimensionally stable at the temperature of heat-treatment, wherein neither plastic material contains any PVC or EVA. A force pressing the surfaces together is preferably applied during connection, wherein the polymer which is no longer dimensionally stable at the temperature of heat-treatment expediently tends to flow under the simultaneous effects of temperature and a compressive force.

Title: Spectrophotometre infrarouge non invasif a emission spontanee
Inventor: BRAIG JAMES R

Granted: 2000-08-29
Abstract: L'invention concerne un procédé et un dispositif qui permettent de surveiller le taux de glucose, d'alcool et d'autres constituants du sang de manière non invasive. Les mesures s'effectuent par contrôle de l'absorption de l'infrarouge par le constituant du sang concerné dans la gamme de l'infrarouge à grande longueur d'onde, où ledit constituant a un spectre d'absorption marqué et discernable. L'énergie infrarouge à grande longueur d'onde émise sous forme de chaleur par le sujet observé est contrôlée et la dose d'infrarouge absorbée par les constituants particuliers du sang (tels que le glucose ou l'alcool) est mesurée par un détecteur d'infrarouge (412) à des longueurs d'onde caractéristiques d'absorption de l'infrarouge par ces constituants. Ces mesures sont de préférence synchronisées avec la systole et la diastole du cycle cardiaque surveillé par un moniteur cardiaque (718), de manière à ce que la part des signaux due aux veines et aux tissus (qui ne produisent pas d'impulsions) puisse être annulée par un microprocesseur (418) quand le rapport des signaux détectés est établi. La concentration des constituants sanguins est ensuite déterminée au moyen d'une équation polynomiale.

Filed: 1995-04-11
Granted: 2005-01-04
Abstract: An apparatus for improving cardiopulmonary resuscitation involves use of a catheter having both an occlusion balloon and a pumping balloon. The occlusion balloon occludes the aorta such that all pumping action will be restricted to the blood vessels above the balloon occlusion. The pumping balloon is cephalad to the occlusion balloon and is preferably pumped in synchronization with external cardiocirculatory resuscitation. The pumping balloon preferably inflates first at the caudal end and then sequentially to the cephalad end in order to provide unidirectional cephalad pumping. Oxygen-carrying fluid may be infused through the lumen into the aorta cephalad of the pumping balloon during use.

Title: Apparatus and method for controlling shared optical pump power sources
Inventor: BAUMGARTEN ARTHUR A
IPC: H01S3/06
Filed: 1999-01-19
Granted: 2001-08-14
Abstract: An optical gain block that is pumped by one or more pump input modules is disclosed. Each pump input module includes a pump source, a pump power control circuit and a bus interface. Each of the available pump input modules detect the presence and pump power of other available pump input modules in order to properly adjust the output power of its own pump source. By controlling the power provided by each of the available pump input modules, the gain block output will be maintained at a specified output power level while all pump input modules share in delivering the required total input pump power. Upon the insertion or removal of any pump input module, the remaining pump input modules will adjust their output power accordingly to maintain the gain block output power at the specified level.

Abstract: A system and method provide a generalized reminder system in an interactive broadcast environment, that enables a viewer to quickly establish reminders for both broadcast events and non-broadcast events, and have such reminders displayed at an appropriate future time. The system includes a broadcast that broadcasts programs, such as television programs and commercial advertisements, and interactive applications associated with various such programs. The interactive applications include reminder interactive applications which have reminder data which describe a future time for displaying a reminder and a description of the event for which the reminder is desired. The broadcast programs and reminder interactive applications are received in broadcast receiver which displays the programs. A viewer viewing a program signals the broadcast receiver to establish a reminder for an event related to the program. The broadcast receiver stores the reminder data from the reminder interactive application, and initiates a timer that expires at the desired future time. When the timer expires, the broadcast receiver displays the event description for the reminder. Reminders may be established and displayed for both broadcast events and non-broadcasts events, as the description of the event is contained in the reminder data.
