CONNECTORS FOR MEDICAL EQUIPMENT

Welch Allyn, Inc., Skane...

1. A blood pressure cuff adapter, comprising:a substantially rigid body having a distal portion, a proximal portion, a substantially cylindrical inner wall forming a central opening of the body, the inner wall extending from the distal portion to the proximal portion, and a longitudinal axis extending substantially centrally through the opening, the distal portion including:
an annular ring having a top surface and a groove, the groove extending at least partly around the longitudinal axis and being configured to accept a corresponding member of a fitting when the fitting is removably attached to the adapter, and
a ridge disposed opposite the top surface, the ridge extending substantially perpendicular to the longitudinal axis, wherein the groove comprises a base, a first sidewall, a second sidewall opposite the first sidewall, and at least one detent disposed on the base, the at least one detent being configured to contact the member as the fitting is rotated about the longitudinal axis of the adapter; and
a seal disposed adjacent to the inner wall, the seal configured to form a substantially fluid-tight seal with the fitting when the fitting is removably attached to the adapter.

BLOOD PRESSURE CUFF

Welch Allyn, Inc., Skane...

1. A blood pressure cuff, comprising:a first bladder comprising a top, and a bottom separate from and opposite the top, the top being sealed to the bottom, the first bladder having a first width, and a first length transverse to the first width;
a second bladder fluidly connected to the first bladder via a passage, the second bladder having a second width substantially equal to the first width, and a second length substantially equal to the first length;
a port fluidly connected to the first bladder, the port comprising a cylindrical central cavity, and a ridge disposed at a distal end of the port, the ridge extending radially away from the central cavity and being configured to connect with a fitting separate from the blood pressure cuff, wherein inflation of the first bladder via the port causes at least partial inflation of the second bladder via the passage; and
a tail formed by the top of the first bladder and the bottom of the first bladder, the tail including a slot configured to overlay the port and accept passage of the ridge therethrough when the blood pressure cuff is worn by a patient.
