    摘要: A valve for controlling the flow of fluid through a flow path, which valve comprises a housing (4) defining a flow path (5) and having two indented portions (3) about the flow path, a poppet (2) mounted within each indented portion such that the internal end of each indented portion defines a seat (8) which provides a fluid tight seal when the associated poppet head is held against the seat, spring means (7) associated with each poppet for holding each poppet against each seat, a rigid moveable member (9) associated with each poppet and adapted to alter the orientation of the associated poppet relative to its seat and thereby seal or unseal the flow path around the poppet, and actuating means (10) for moving each movable member; and inflator apparatus incorporating at least one valve.

    摘要: An electronically controlled syringe system (14a) for connection to a balloon catheter or other balloon-type member and for automatically monitoring, displaying and recording inflation data when the syringe system is used to inflate the balloon of the catheter or other balloon-type member. A syringe (16) having a barrel (22) and a syringe plunger (24) is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger (24) further into the barrel (22). Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger (24) toward the rear of the barrel (22). A piezoresistive semiconductor transducer housed on the barrel (22) of the syringe (16) senses fluid pressure applied by the syringe. The electric signal output by the transducer is input to a controller (20a) where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is automatically displayed and recorded. In one embodiment, the controller (20a) is also mounted onto the syringe barrel (22) to provide a digitally controlled inflation syringe system that is completely self-contained, and disposable.

    摘要: Providing fluid to an internal delivery site of a patient includes moving the fluid from a fluid reservoir through a conduit and through a delivery device at the delivery site while maintaining the fluid at a predetermined pressure. The delivery device may comprise an inflatable balloon with apertures formed in its periphery for directing the fluid into the vessel walls. Pressurized fluid is provided through the apertures of the balloon to the vessel wall. The pressure is automatically controlled to avoid both pressure spikes and unacceptable deflation of the balloon during administration of the fluid. A further feature includes comparing the pressure with the volume infused and in the event that pressure decreases while the volume infused increases beyond certain limits, the delivery of the fluid is stopped. Further features include a timer for limiting the inflation time of the delivery device and a volume detector for controlling the amount of fluid delivered. In one described embodiment, a pneumatic driver system is used to pressurize the fluid.

    摘要: Système de seringue à commande électronique (14a) se raccordant à un cathéter de type ballon ou à un autre élément de type ballon et servant à contrôler, à afficher et à enregistrer automatiquement les données de gonflage quand on utilise le système de seringue pour gonfler le ballon du cathéter ou un autre élément de type ballon. Une seringue (16) comportant un cylindre (22) et un piston (24) fonctionne sélectivement pour augmenter la pression fluidique appliquée au cathéter ballon ou autre élément de type ballon au moyen de l'enfoncement du piston (24) dans le cylindre (22). On relâche la pression positive appliquée au cathéter ballon ou autre élément du même type en tirant le piston (24) vers l'arrière du cylindre (22). Un transducteur piézorésistif à semiconducteurs placé sur le cylindre (22) de la seringue (16) détecte la pression du fluide appliquée par la seringue. Le signal électrique émis par le transducteur est transmis dans un dispositif de contrôle (20a) dans lequel ledit signal est traité numériquement, afin de calculer et d'enregistrer les données électroniques représentant l'intensité de la pression fluidique appliquée et, également, afin de calculer la durée d'application de ladite pression. Les données électroniques représentant ladite information sont affichées et enregistrées automatiquement. Dans un mode de réalisation de l'invention, le dispositif de contrôle (20a) est également monté sur le cylindre de la seringue (22), afin de constituer un système de seringue de gonflage à commande numérique, totalement autonome et jetable.

    摘要: In an apparatus for performing the coronary transluminal angioplasty, a tubular body (2) is housed in a shell (1) and has a disposable syringe (7) removably fixed thereto. A balloon catheter (8a) is connected to the syringe (7). A slide (20) runs axially inside the tubular body (2) and has a sleeve (17) fastened to it for pushing onto the plunger (18) of the syringe (7) so as to force inflation liquid into the catheter (8a). A threaded rod (11), that runs through the sleeve (17) and engages with a threaded section (20a) of the slide (20), is rotated by an electric motor (9) through a drive link (10) and pushes, with the opposite end onto a saddle (24) that in turn pushes onto a load sensing cell (31), while a counter device detects the number of rouds of the threaded rod (11) for metering the liquid forced into the catheter.

    摘要: Un système de gonflage est destiné à la pressurisation et la dépressurisation d'un cathéter à ballon. Le système de gonflage comprend une seringue (12) ayant un cylindre (14), un plongeur (16) avec un filetage expansible (66a-d), une poignée avec came, un couvercle d'extrémité (20) de la seringue, une jauge de pression (22), un tubage flexible (24), et des dispositifs de raccordement. La seringue est structurée de sorte qu'une partie du cylindre de la seringue présente un filetage interne qui s'engage avec les filetages expansibles du piston. Dans un mode de désolidarisation, le piston coulisse librement dans le cylindre de la seringue permettant un mouvement rapide pour purger, pressuriser ou dépressuriser le système de gonflage. Une fois que la pression a atteint un niveau prédéterminé dans le système, la came sur la poignée provoque automatiquement le verrouillage du filetage contre le cylindre de la seringue, et la pressurisation ou dépressurisation continue s'effectue par la rotation de la poignée du piston par rapport au cylindre de la seringue. Un avantage du système de gonflage ci-décrit réside dans le fait que le verrouillage de la seringue en vue d'une pressurisation et d'une dépressurisation contrôlées se fait en une seule étape.

    摘要: The present invention is a fluid injecting device (10). It is comprised of an elongated housing (12) having an inner bore (13) and a piston (16) slidably disposed therein. Attached to the piston (16) is an elongated piston rod (18) one end of which extends out of the housing (12). The rod (18) has a threaded intermediate section which engages a plurality of opposed threaded members. With this construction longitudinal movement of the piston (16) within the bore (13) is effected by rotating the piston rod (18). The invention also includes means to move the opposed threaded members to a second position spaced away from the piston rod (18) and disengaged therefrom. In this fashion longitudinal movement of the piston (16) within the bore (13) is effected by pushing or pulling on the piston rod (18).
