Abstract: L'invention concerne un dispositif d'accès à un orifice conçu pour conférer un accès à long terme à un orifice implanté dans un patient et comprenant deux composants principaux: un ensemble de perfusion et un dispositif d'insertion d'aiguille de sécurité. L'ensemble de perfusion comprend un boîtier pouvant être conçu selon une forme spécifique, par exemple, un dôme. Une canule mousse est fixée sur le côté inférieur du boîtier de l'élément de perfusion et s'étend vers le bas à partir de celui-ci. Une tubulure ou un cathéter est également connecté au boîtier de l'élément de perfusion, de préférence, sur un côté de celui-ci. L'ensemble d'insertion d'aiguille de sécurité comprend une base présentant une partie proximale conçue pour s'adapter sur le boîtier de l'élément de perfusion. Des montants sont placés au niveau de la partie distale de la base, de manière qu'une seconde extrémité d'un bras, une aiguille ou une canule pointue étant connectée sur la première partie de celui-ci, puisse être connectée amovible et articulé à la base. La canule pointue s'étend à partir du côté inférieur de l'extrémité proximale du bras et passe à travers la base par le biais d'un alésage formé au niveau de la partie proximale de la base. L'alésage est défini entre une ouverture ménagée au niveau du côté inférieur de la base et une ouverture ménagée au niveau de la surface supérieure de la base. Des mécanismes de verrouillage sont prévus au niveau des montants de la base et de l'extrémité distale du bras, de manière que quand le bras est déplacé à distance de la base et au moment où l'extrémité distale du bras pivote autour des montants, les mécanismes de verrouillage respectifs placés au niveau du bras et de la base viennent en contact, afin de verrouiller le bras en place, maintenant ainsi la pointe de l'aiguille dans l'alésage formé dans la base. Pendant l'utilisation, l'élément d'insertion d'aiguille de sécurité est placé sur l'ensemble de perfusion, la canule pointue s'étendant à travers le boîtier de l'élément de perfusion et s'adaptant axialement avec la canule mousse de l'ensemble de perfusion, la pointe de la canule pointue étant en saillie au-delà de la pointe de la canule mousse. La combinaison de l'élément d'insertion d'aiguille/ensmeble de perfusion est appuyée contre la surface de la peau du patient, de manière que la combinaison des canules pointue/mousse pénètre dans le patient et ponctionne la cloison auto-obturante d'un réservoir à orifice implanté dans le patient. Une fois l'élément d'insertion d'aiguille de sécurité retiré de l'ensemble de perfusion et du fait que la cloison du boîtier de perfusion est auto-obturante, une voie de communication fluidique fermée est établie entre le réservoir à orifice et un réservoir de fluide pouvant être connecté au cathéter de l'ensemble de perfusion. Un accès à long terme du réservoir à orifice implanté est ainsi obtenu.

Abstract: A popup drain stopper assembly includes a pivoting body and a pipe fitting having a sidewall access port with an external sealing seat. The pipe fitting supports the pivoting body and forms a seal to prevent liquids that flow down a drain to which the pipe fitting is attached from leaking through the sidewall access port past the pivoting body. An external lever is connected to the pivoting body to provide means by which the pivoting body is pivoted. A stopper with a depending body that carries an in-drain coupling member is provided. The stopper is raised and lowered by the in-drain coupling member during normal operation in accordance with the pivotal positioning of the pivoting body. The in-drain coupling member is removable for maintenance and inspection with the stopper and is detachably secured to the pivoting body to facilitate such removal.

Abstract: Un cathéter permet des mesures de lumière en temps réel, par exemple, sans limites, le facteur de réflexion diffuse , la fluorescence, etc., provenant de matériaux biologiques, comme un tissu (y compris le sang), tout en réalisant une ablation par RF. Le modèle de pointe de cathéter isole les parcours dillumination et de collecte de sorte que la lumière quitte la pointe du cathéter et circule dans le tissu dintérêt (p. ex., tissu cardiaque ou sang) avant de retourner à la pointe de cathéter. Un tel modèle évite avantageusement la saturation du détecteur optique et assure la diffusion de léclairage dillumination dans le milieu dintérêt. Le cathéter comprend un corps de cathéter et une électrode de pointe. Lélectrode de pointe présente une enveloppe extérieure, une couche intérieure de matériau diffus et une cavité creuse, où la couche interne est configurée pour transmettre la lumière à lextérieur de lélectrode de pointe vers un tissu au moyen dun ensemble douvertures dillumination dans la paroi de lenveloppe et la cavité creuse est configurée pour recevoir la lumière du tissu au moyen douvertures de collecte dans la paroi de lenveloppe et la couche intérieure. Une surface intérieure de la couche intérieure présente un revêtement opaque servant à isoler la lumière injectée dans la couche intérieure de la lumière recueillie dans la cavité creuse. Il y a un premier guide donde optique sétendant entre le corps de cathéter et lélectrode de pointe pour injecter la lumière dans la couche intérieure et illuminer le tissu et un deuxième guide donde optique sétendant entre le corps de cathéter et lélectrode de pointe pour recueillir la lumière recapturée dans la cavité creuse.

Abstract: A high efficiency gasification process for converting carbonaceous solids to methane and apparatus for its practice are described. The process includes reacting steam and carbonaceous solids comprising ash in the presence of alkali metal catalyst in a gasification reactor to produce combustible gases and char particles comprising ash and alkali metal catalyst constituents, treating a stream of such char particles in an alkali metal catalyst recovery system to recover the catalyst constituents as alkali metal compounds, and recycling such recovered compounds. Within the alkali metal catalyst recovery system the process includes quenching the stream of char particles with water whereby such particles are cooled and fractured, dissolving soluble alkali metal catalyst constituents from the fractured solids to form a first alkali metal catalyst solution and washed solids, optionally reacting the washed solids in alkaline solution to form a second alkali metal catalyst solution, upgrading said first and optional second alkali solution to recover the alkali metal catalyst constituents as said alkali metal compounds.

Abstract: This invention relates to a method and apparatus of detecting and compensating for DC residual fault currents on electrical systems. In particular, the present invention relates to a method and apparatus which is capable of accurately detecting one or more parameters of the fault current waveform and generating a compensation factor which compensates for specific pulsed DC fault components present. In this way, trip sensitivity is optimised for all types of fault current waveforms. In a preferred embodiment, the present invention operates by detecting one or more parameters of the encoded fault current waveform and generating a measure of symmetry comparing the mean squared values of negative and positive sections of said encoded fault current waveform. In use, various bands of the ratio of the mean squared sum of the positive and negative sections of said encoded fault current waveform are obtained, and a compensation factor is determined from a look-up table stored in a processing means.
