Filed:

Jul 6, 2005

Appl. No.:

11/175627

Inventors:

Stephen A. Anderson - Thompson Station TN, US
Richard C. Dowdy - Colleyville TX, US

Assignee:

Egret Medical Products, Inc. - Garland TX

International Classification:

A61M 16/00

US Classification:

12820716, 12820026, 128912

Abstract:

A respiratory suction catheter assembly includes a manifold supporting a rotatable swivel member for engagement with an endotracheal tube, and a seal support body disposed on a boss of the manifold opposite the part supporting the swivel for supporting a catheter tube seal and a porous filter for filtering air flowing into and out of a flexible elongated sheath enclosing the catheter tube. The sheath includes opposed tapered ends secured to the seal support body and to a boss on a suction control valve housing. The valve housing supports a tapered plug closure member engageable with a resilient actuator and a slide-lock member. Certain components, including the sheath, the seal support body, the filter, the catheter tube seal and the catheter tube may be treated with an anti-microbial agent.

Abstract:

A suction catheter assembly, particularly adapted for neonatal use includes a distal manifold body including a rotatable connector for connection to an endotracheal tube, a ventilating port member and an ancillary catheter receiving port member. The manifold body is rotatably joined to a catheter tube seal housing. The seal housing includes an irrigation port member. A catheter tube wiper seal and a filter member are disposed in the seal housing which is joined to a suction control valve assembly by an elongated flexible sheath defining an enclosed space through which the catheter tube extends between the valve assembly and the manifold. A resilient closure member actuator and slide lock member are engageable with a closure member of the valve assembly.

International Classification:

US Classification:

Abstract:

If an individual maintains an unlisted number, it is difficult, or impossible, for an individual to get in touch with the unlisted party via the unlisted telephone number. However, through the use of an unlisted number call messaging service, a calling party is able to leave a message for an unlisted party. In particular, the calling party leaves a message for the unlisted party. The message is associated with the unlisted party and the unlisted party is notified of the message via a predetermined procedure. The unlisted party, upon receipt of the message notification, then has the option to, for example, review the message.
