Filed:

Nov 1, 1984

Appl. No.:

6/667115

Inventors:

Douglas F. DeVries - Redlands CA
Arie Cohen - Walnut CA

Assignee:

Bear Medical Systems, Inc. - Riverside CA

International Classification:

A61M 1600

US Classification:

12820423

Abstract:

A volume ventilator is disclosed which has a balloon valve type exhalation valve for permitting release of gases to the ambient environment during the exhalation period of artificial ventilation or spontaneous breathing, or when there is excess proximal pressure in the ventilator system. A pressure transducer continuously senses the proximal pressure in the ventilator system and sends to a microcomputer controller and associated circuitry of the ventilator system a signal indicative of the instantaneous proximal pressure. The pressure in the balloon, which is the pilot pressure of the exhalation valve, is regulated through a jet venturi type pressure controller which is connected to a source of pressurized gas. The gas flows through the jet venturi, wherein its flow rate is regulated by a ball valve moving against a suitable valve seat. The ball valve is controlled by a stepper motor through a cam follower.

Abstract:

A system for mounting various pieces of equipment at selected locations along the length of a support member. A clamping unit, releasably mounted on the support member for adjustable positioning of the clamping unit, is fixed in place by the action of locking means which draw a protrusion on a clamping piece into intimate contact with opposed contact surfaces in a groove running along the length of the support member. The opposed contact surfaces of the groove form an acute angle transverse to the length of the support member. With the support member formed as an open channel, cables from the equipment being mounted can be positioned within the channel and clips snap-fitted into the opening in the channel close off the opening in the channel at selected locations and form smaller openings through which the cables pass.
