Ventilator manifold with accessory access port and adaptors therefore
First Claim
1. The combination of a ventilator manifold for use with a respiratory support system, and an adaptor for a respiratory system accessory device, said manifold comprising:
- means for fluid flow connection between a patient and a ventilator circuit,means including an accessory access port for allowing attachment of said adaptor to said manifold, said accessory access port being normally closed against fluid flow therethrough into said manifold, said adaptor comprising a generally hollow tubular member having a proximal end and a distal end, said proximal end having means for releasably attaching to the respiratory system accessory device, and said distal end including opening means for opening said normally closed accessory access port.

Abstract
A ventilator manifold and adaptors therefore are disclosed which allow attachment of respiratory system accessory devices to the ventilator manifold without loss of PEEP. The manifold includes an accessory access port which has a normally closed valve therein which remains closed regardless of the pressure changes within the manifold. The normally closed valve is positioned in the accessory access port such that placement of an adaptor therein forces the normally closed valve to an open position, and removal of the adaptor allows the normally closed valve to return to its closed position. The adaptors are formed to allow attachment of accessory devices such as an ambulatory resuscitation bag, a metered dose inhaler, and a bronchial scope. The adaptors may also include a locking ring thereon for locking the adaptor in position in the accessory access port. Further, the manifold and adaptors may also be designed to allow the injection of fluid through the accessory access port into the manifold for cleaning or lavage.

9. A method of attaching a respiratory system accessory device to a respiratory support system by means of an adaptor for use of the respiratory system accessory device on a patient, the respiratory support system including a manifold which is in fluid flow connection between the patient and a ventilator circuit, the manifold including a normally closed accessory access port and the adaptor including an opening means, said method steps including:
- removably inserting a portion of the adaptor including the opening means into the normally closed accessory access port of the manifold to Open the normally closed accessory access port to allow fluid flow access between the manifold and the adaptor,
removably attaching a respiratory system accessory device to the adaptor, using the respiratory system accessory device on the patient, and removing the adaptor from the manifold. - View Dependent Claims (10, 11, 12)
