Abstract: The present invention provides a diaphragm for use in pump applications in which at least a predetermined portion of such diaphragm is in contact with such outer piston which would tend to abrade such diaphragm. Such diaphragm is formed from at least one layer of a preselected flexible material. Such diaphragm comprises an outer bead like portion for securing the diaphragm to a pump housing. There is a annular flexure portion having a first end and a second end, such first end and such second end being generally flat and an arcuate shaped middle portion formed contiguously with the first end and the second end. Such first end is formed contiguously with the outer bead like portion. Such annular flexure portion, has a substantially uniform first predetermined thickness. An enlarged bulbous portion is formed contiguously with the second end and extends around an inner periphery thereof. Such enlarged bulbous portion has a predetermined configuration.      Such diaphragm has an enlarged section formed as a protrusion that extends outwardly from an outer surface of the generally flat second end. Such enlarged section is formed contiguously with the enlarged bulbous portion and extends around an outer periphery thereof. The enlarged section causes the second end to be thicker than such first predetermined thickness.      Further, there is a generally flat center portion that is formed contiguously with the enlarged bulbous portion and extends around an inner periphery thereof.

Granted: 2004-04-20
Abstract: La présente invention concerne un appareil permettant de déterminer la phase instantanée du cycle respiratoire, le débit ventilatoire moyen du patient et la nécessité de fournir une assistance ventilatoire. En l'occurrence, un microprocesseur (16) reçoit un signal de débit d'air fourni par un transducteur manométrique (18) couplé à un connecteur (17) d'un inhalateur (11). Le microprocesseur (16) pilote un asservissement (19) qui commande le moteur de ventilation (20) et partant, détermine la pression de l'air fourni par la soufflante (10). Un conduit (12) raccorde cette soufflante (10) à l'inhalateur (11) du sujet. L'invention vise à répondre à plusieurs nécessités. En effet, l'assistance ventilatoire apportée doit être étroitement synchrone avec les efforts du sujet tant que le sujet est éveillé et fait des efforts relativement important. La machine doit adapter automatiquement son niveau d'assistance de façon à entretenir un niveau de ventilation minimum, et ce, sans que la qualité des chimioréflexes du patient n'entre en ligne de compte. L'appareil doit enfin continuer à fonctionner correctement, même en cas de fuites importantes.
