Title: Antibacterial medical tubing connector
Inventor: FOLDEN THOMAS I
IPC: A61M39/18
Filed: 1995-02-14
Granted: 2006-05-09
Abstract: An antimicrobial tubing connector for medical procedures, especially for extracorporeal connections as in peritoneal dialysis and hemodialysis tubing sets. A male portion (110) includes a central tube (112) surrounded by a sleeve (120) radially spaced apart from the central tube to define an annular space. A mating female portion (10) includes a tubular body (16) which receives the central tube of the male portion and which is received by the annular space. A set of O-ring seals (22, 36) and mating threads (32, 128) produces a secure fluid-tight connection.  An antimicrobial agent such as silver is deposited on one or more of several surfaces, preferably by a durable process such as ion assisted deposition, to prevent touch contamination.  Either or both of the male and female portions may be capped with a separate cap, which may also receive the antimicrobial agent.

The arrangement is such that the web (W) is supported by the blanket (20) with the web (W) being disposed between the blanket (20) and the backing roll (12). A lubricant (26) is supplied between the concave surface (18) and the blanket (20) such that the blanket (20) is slidingly supported by the concave surface (18) during passage of the blanket (20) through the extended nip (16). The concave surface (18) encompasses a pocket (28) defined by the shoe (14). The arrangement is such that the pocket (28) is filled with lubricant (26) flowing from the concave surface (18) so that in the event of a wad of the web entering into the extended nip (16), the wad is yieldingly received within the pocket (28) so that damage to the blanket (20) by the wad is minimized.

Abstract: A switch includes switching elements which are mounted within a sealed radio frequency cavity. The switching elements provide electrical contact paths between contact portions of connectors which project into the cavity. The switching elements are urged against the contacts by magnetic forces. During operation, unselected paths have their switching elements grounded out by the action of external magnets which attract the unselected switching elements to a ground plate with a magnetic force which overcomes the magnetic forces urging the switching elements against the contacts.

Title: Systeme de stimulation cardiaque bi-cavite et procede permettant le reglage optimal de l'intervalle d'echappement auriculo-ventriculaire pour traiter la myocardiopathie

Granted: 2002-02-05
Abstract: La présente invention concerne un système et un procédé de stimulation cardiaque bi-cavité destinés à une thérapie par stimulation de la myocardiopathie obstructive et similaire. Le procédé consiste à rechercher ou analyser les valeurs de l'intervalle d'échappement auriculo-ventriculaire pour définir une valeur optimale correspondant approximativement à la valeur de l'intervalle d'échappement auriculo-ventriculaire le plus long nécessaire pour une détection complète en réponse à une impulsion de stimulation ventriculaire délivrée. Dans un mode de réalisation préféré, le système et le procédé détectent et traitent des signaux FFRS provenant de l'électrode auriculaire et produits autrement, et obtiennent, à partir de ces signaux, une caractéristique évaluée en vue de déterminer l'intervalle d'échappement auriculo-ventriculaire optimal. Dans un mode de réalisation spécifique, les intervalles de temps entre les impulsions de stimulation ventriculaire délivrées et les signaux FFRS résultants sont analysés en fonction de l'intervalle d'échappement auriculo-ventriculaire. L'intervalle d'échappement auriculo-ventriculaire optimal choisi correspond approximativement à l'intervalle d'échappement auriculo-ventriculaire le plus long correspondant à l'intervalle de temps le plus long, c'est-à-dire à environ le coude de la courbe durée FFRS/intervalle d'échappement auriculo-ventriculaire. Dans encore un autre mode de réalisation, la caractéristique FFRS utilisée est la durée, le système déterminant l'intervalle d'échappement auriculo-ventriculaire le plus long correspondant à la valeur de durée la plus élevée. Ce système et ce procédé sont utilisables avec un module de programmation externe, ou peuvent être adaptés pour fonctionner automatiquement dans un stimulateur cardiaque implanté.
