Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
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.
Claim 2
Dependent Claim
111 words
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.
Claim 3
Dependent Claim
17 words
The combination of claim 1 wherein said accessory access port includes a relatively flexible sleeve formed therein.
Claim 4
Dependent Claim
61 words
The combination of claim 1 wherein said accessory access port includes a normally closed valve therein, whereby, said normally closed valve is closed to fluid flow through said accessory access port and is forced to an open position by said opening means of said adaptor to allow fluid flow through said accessory access port when said adaptor is properly attached thereto.
Claim 5
Dependent Claim
24 words
The combination of claim 3 further including means for locking said adaptor to said accessory access port when said adaptor is properly attached thereto.
Claim 6
Dependent Claim
31 words
The combination of claim 1 wherein said opening means for opening said normally closed valve means further includes means for maintaining a seal between said adaptor and said accessory access port.
Claim 7
Dependent Claim
21 words
The combination of claim 5 wherein said proximal end of said adaptor includes means for receiving a metered dose injection canister.
Claim 8
Dependent Claim
23 words
The combination of claim 5 wherein said proximal end of said adaptor includes means for allowing insertion of an endoscope through said adaptor.
Claim 9
Dependent Claim
40 words
The combination of claim 7 wherein said means for allowing insertion of an endoscope forms an opening through which an endoscope may pass into said adaptor, and further includes means for closing said opening when no endoscope is positioned therein.
Claim 10
Independent Claim
136 words
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.
Claim 11
Independent Claim
136 words
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.
Claim 12
Dependent Claim
28 words
The method of claim 9 wherein said step of attaching a respiratory system accessory device to the manifold includes attaching a metered dose injection canister to the adaptor.
Claim 13
Dependent Claim
27 words
The method of claim 9 wherein said step of attaching a respiratory system accessory device to the adaptor includes attaching an ambulatory resuscitation bag to the adaptor.
Claim 14
Dependent Claim
25 words
The method of claim 9 wherein said step of attaching a respiratory system accessory device to the adaptor includes attaching an endoscope to the adaptor.
