Respiratory accessory access port and adaptor therefore
First Claim
1. A respiration system for use with respiration system accessories, comprising:
- a manifold for connecting a patient to a ventilator circuit said manifold including an accessory access port,an adaptor for attachment to said manifold, said adaptor being formed of a generally hollow tubular member having a proximal end and a distal end, said distal end including a cylindrical central section sized to be received within said accessory port, andsaid accessory access port allowing attachment of said adaptor to said manifold, said accessory access port including a normally closed valve formed of a soft elastomeric material which is closed to fluid flow through said accessory access port when said adaptor is not present therein, said adaptor having means for forcing said valve to an open position to allow fluid flow through said accessory access port responsive to said cylindrical central section of said adaptor being positioned completely within said accessory access port, said valve completely surrounding any portion of said cylindrical central section of said adaptor in a sealing manner to seal against fluid flow between said accessory access port and the outside of said cylindrical central section whenever any portion of said cylindrical central section is positioned within said accessory access port.

Abstract
An endotracheal respiration system which includes a respirator manifold with a port for attachment and detachment of an accessory device thereto without interruption of continuous respiratory support of the patient. A particular embodiment includes a suctioning system for removal of fluids from a patient'"'"'s lungs during respiratory support. The manifold of the respiration system includes an accessory access port which has a normally closed valve therein which remains closed regardless of the pressure changes within the manifold. However, the normally closed valve is positioned in the port such that placement of a specially designed male adaptor located on the suctioning device forces the normally closed valve to an open position, thus allowing passage of a suction catheter through the manifold into the patient. Removal of the male adaptor of the suctioning device allows the normally closed valve to return to its closed position, thus allowing continued operation of the respirator even when no accessory device is present in the accessory device access port. The male adaptor includes a housing which is specially adapted to be securable within the valve in the access port of the manifold so as to substantially inhibit pressure loss from the manifold while simultaneously forcing the valve to an open position.
