Abstract
Adaptive attachments used in combination with a blood pressure cuff enable various blood pressure measurements to be taken in a hospital or other setting having various single and/or dual lumen manual or electronic blood pressure measuring equipment with a single, patient-worn cuff.
Claims18
A cuff configured to be wrapped about a limb of a patient for conducting blood pressure measurements, the cuff comprising:
- an inflatable chamber;
- an external surface;
- and
- a first adapter connected to the inflatable chamber, the first adapter including:
- a main body having an opening providing direct fluid communication between the external surface and the inflatable chamber, wherein the opening is defined by an inner diameter of the main body, the inner diameter of the main body being configured to form a friction-fit with an outer diameter of a second adapter releasably attachable to the first adapter, wherein
- the main body further includes a ridge extending radially away from the opening, the ridge being configured such that a distalmost portion of the second adapter is disposed radially inward of the ridge when the inner diameter of the main body forms the friction-fit with the outer diameter of the second adapter.

A cuff configured to be wrapped about a limb of a patient for conducting blood pressure measurements, the cuff comprising:
- an inflatable chamber;
- an external surface;
- a first adapter connected to the inflatable chamber, the first adapter including a main body having an opening providing direct fluid communication between the external surface and the inflatable chamber, wherein the opening is defined by an inner diameter of the main body;
- and
- a circumferential seal having an inner diameter, the inner diameter of the circumferential seal being configured to form a substantially fluid-tight seal with an outer diameter of a second adapter releasably attachable to the first adapter when at least part of the second adapter is disposed proximal to and radially inward of the opening, wherein
- the main body further includes a ridge extending radially away from the opening, the circumferential seal and the ridge being configured such that a distalmost portion of the second adapter is disposed radially inward of the ridge when the inner diameter of the circumferential seal forms the substantially fluid-tight seal with the outer diameter of the second adapter.

A cuff configured to be wrapped about a limb of a patient for conducting blood pressure measurements, the cuff comprising:
- an inflatable chamber;
- an external surface;
- a first adapter connected to the inflatable chamber and configured to interface with a second adapter releasably attachable to the first adapter, the first adapter having a main body comprising a substantially cylindrical inner channel, the inner channel extending from a distal end of the first adapter to a proximal end of the first adapter, the inner channel including an opening providing direct fluid communication between the external surface and the inflatable chamber, wherein
- the main body defines a longitudinal axis extending substantially centrally through the inner channel and the opening, the longitudinal axis extending substantially perpendicular to the external surface throughout the inner channel;
- a circumferential seal disposed proximate the opening and having a diameter greater than a diameter of the inner channel, the circumferential seal being configured to form a substantially fluid-tight seal with the second adapter when the second adapter is releasably attached to the first adapter;
- and
- the main body further includes a ridge extending radially away from the opening, the ridge being configured such that a distalmost portion of the second adapter is disposed radially inward of the ridge when the inner diameter of the main body forms the friction-fit with the outer diameter of the second adapter.
