1. A vest to apply pneumatic pressure delivered by a hose to a chest of a patient, the vest comprising:
- a flexible belt including an inflatable bladder; and
a connector for connection between the inflatable bladder and the hose, the connector comprising an elastic sheet forming a portion of a wall of the inflatable bladder; and
a first slot within the sheet that extends in a direction generally perpendicular to a longitudinal dimension of the belt and that is dimensioned to form an airtight seal around an outer surface of the hose, the elastic sheet having a generally flat configuration along a plane defined by the belt prior to insertion of the hose through the slot, and the elastic sheet being deformable to allow the hose to be inserted through the slot in a direction generally parallel to the plane defined by the belt and generally perpendicular to a longitudinal dimension of the slot.

Abstract
An improved connector having limited durability for a disposable chest compression vest is quiet and cost effective. Among other advantages, the connector is heat sterilizable and flat so that the vest can be efficiently packaged and stacked, which is particularly beneficial for use in a hospital.

7. A vest to apply pneumatic pressure delivered by a hose to a chest of a patient, the vest comprising:
-
a flexible belt having a generally flat configuration and including an inflatable bladder, the bladder having a generally flat configuration when deflated; and a connector for connection between the inflatable bladder and the hose, the connector comprising a thermoplastic elastomer sheet having a durometer hardness rating that provides limited durability to the connector;
a slot within the thermoplastic elastomer sheet that extends in a direction generally perpendicular to a longitudinal dimension of the belt and that is dimensioned to form an airtight seal between the inflatable bladder and the hose, the slot further comprising a slit;
holes at ends of the slit;
tabs at intersections between the slit and the holes; and
wherein no leakage occurs around the holes, because the holes have a diameter that allows the tabs to recede when the slot is stretched open by the hose;
the thermoplastic elastomer sheet having a generally flat configuration along a plane defined by the belt prior to insertion of the hose through the slot, and the thermoplastic elastomer sheet being deformable to allow the hose to be inserted through the slot in a direction generally parallel to the plane defined by the belt and generally perpendicular to a longitudinal dimension of the slot. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A vest to apply pneumatic pressure delivered by a hose to a chest of a patient, the vest comprising:
-
a flexible belt having a generally flat configuration including an inflatable bladder, the bladder having a generally flat configuration when deflated; and a connector for connection between the inflatable bladder and the hose, the connector comprising an elastic sheet forming a portion of a wall of the inflatable bladder, the elastic sheet having a durometer hardness rating and a thickness; and
a first slot within the sheet that extends in a direction generally perpendicular to a longitudinal dimension of the belt, the slot having dimensions dependent on the durometer hardness and thickness of the sheet and form an airtight seal around an outer surface of the hose, the elastic sheet having a generally flat configuration along a plane defined by the belt prior to insertion of the hose through the slot, and the elastic sheet being deformable to allow the hose to be inserted through the slot in a direction generally parallel to the plane defined by the belt and generally perpendicular to a longitudinal dimension of the slot. - View Dependent Claims (19, 20)

21. A pneumatic chest compression vest comprising:
-
a front panel with an inner and outer surface; an air bladder on the inner surface; a belt connected to the front panel for securing the vest; a connector for connecting the air bladder to a hose, the connector further comprising;
an elastic sheet forming a portion of a wall of the inflatable bladder; and
a first slot within the sheet dimensioned to form an airtight seal around an outer surface of the hose when the hose is inserted through the slot in a direction generally parallel to the sheet; andan indicator for indicating prior use of the vest and tampering with the vest. - View Dependent Claims (22, 23, 24, 25, 26)

27. A pneumatic chest compression vest comprising:
-
a front panel with an inner and outer surface; an air bladder on the inner surface; a belt connected to the front panel for securing the vest; and a connector to connect the air bladder to a hose, the connector being comprised of a thermoplastic elastomer having a durometer hardness rating that provides limited durability of the connector, a slot within the thermoplastic elastomer dimensioned to form an airtight seal between the inflatable bladder and the hose, the slot further comprising;
a slit;
holes at ends of the slit for easy insertion of the hose into the slot;
tabs at the intersection of the slit and the holes; and
wherein no leakage occurs around the holes, because the holes have a diameter that allows the tabs to recede when the slot is stretched open; andan indicator for indicating prior use of the vest and tampering with the vest. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
