초록 ▼

A continuously positive-pressure respiratory aid, providing positive-pressure inhalation and exhalation of a patient suffering from apnea or other respiratory disorder in which forced breathing-assistance is to be administered. A source of pressurized air, an outlet to a face mask, and a vent outlet all are in parallel communication; and the vent is controlled by a spring-pressed valve body which is adjustable to control the above-atmospheric pressure to individual patient\s needs. A safety feature provides that the valve body is sufficiently in vent position for the patient\s exhalation even if the valve body is somehow blocked from its normal vent movement; and a viscous grease in the support of the valve body prevents objectionable resonant chatter.

대표청구항 ▼

A respiratory aid device carrying a face mask body which fits over the nose and mouth of a patient, the device and mask body providing positive pressure inhalation and exhalation for a patient, comprising, in combination: a body member means having a chamber; the body member means having an inlet means for communicating with an associated source of pressurized respiratory air for the patient, a first outlet means communicating with the patient\s face mask body, and a second outlet means which provides a vent; the inlet means, the first outlet means, and the second outlet means being in communication with the chamber of the said body member means; the second outlet means being provided with a closure valve body having inner and outer perimeters, a valve seat means associted with the second outlet means; a control body means carrying said closure valve body and being relatively movable with respect to the closure valve body, and having abutment means which abuttingly engage the closure valve body adjacent its inner perimeter and said seat means being engagable with said closure valve body around its outer perimeter; said closure valve body being movable into and between positions of (a) toward or into a closed position of non-venting, where the inlet means imparts pressure to the first outlet means and face mask body and hence to the patient for inhalation instead of being vented out the second outlet means, and (b) an open position of venting the body member means chamber of both the pressure in the inlet means and the pressure in the first outlet means and face mask body, during periods of exhalation by the patient, and to vent excess air not being used during periods of dwell and inhalation; means permitting said closure valve body to move into a partially open position even when a portion of said closure valve body is accidently restrained against movement from said closed position, said means including a rockable mounting for said closure valve body on said control body means; there being provided support means for the control body means which support the control body means so as to enable it to move along an axis perpendicular to the general plane of the valve seat means, said control body being movable along said axis between three different positions, including; (a) a first position in which the entirety of the abutment means and the entirety of the valve seat means both engage said inner and outer perimeters of said closure valve body, respectively, (b) a second position in which said inner perimeter of said closure valve body engages the entirety of said abutment means and the outer perimeter of said closure valve boyd is spaced from said valve seat, and (c) a third position constituting said partially open position in which the inner and outer perimeters of said closure valve body engage only a portion of said abutment means and said valve seat means, respectively; the relative movability of the control body means and the closure valve body providing that if debris or other external cause prevents a portion of the closure valve body from being moved from said closed position of non-venting, the closure valve body is movable with respect to the control body means, thereby providing that other portions of the closure valve body are permitted to be moved to the open position to vent the chamber of the body member means.
