Low deadspace airway adapter
First Claim
Patent Images
1. An airway adapter structure comprising:
- (a) a substantially tubular first portion comprising;
(1) a wall having a first end portion, a second end portion, and a first bore defined therein, and(2) a protrusion operatively coupled to the wall and having a second bore defined therethrough, wherein the protrusion is axially aligned with the first bore;
(b) a longitudinally compressible member coupled to the protrusion such that a first portion of the compressible member extends beyond an end of the protrusion, wherein the first portion of the compressible member includes a third bore defined therein in communication with the second bore; and
(c) a substantially tubular second portion coupled to the first end portion of the tubular first portion, wherein a fourth bore is defined in the second portion, and wherein the second bore, the third bore, and the fourth bore are in fluid communication so as to define at least a portion of a gas flow path through the airway adapter.

Abstract
An airway adapter suitable for use with patients having low tidal volumes, e.g., neonates, which minimizes deadspace in the airway and promotes smooth flow of gases through the adapter. The adapter includes a first portion adapted to couple to a tubular adapter, such as an endotracheal tube adapter, and a second portion adapted to couple to a ventilation tube. A longitudinally compressible member is coupled to the first portion to minimize deadspace in the adapter. A portion of the compressible member resiliently contacts and seals against a tubular adapter upon assembly of the airway adapter therewith.
