Reversible blood pressure measurement cuff and manufacturing method therefor

A blood pressure cuff, comprising:

• a longitudinal axis that extends substantially centrally along a length of the blood pressure cuff;
• a first bladder extending along the longitudinal axis from a first cuff perimeter segment to a lateral seal that extends substantially perpendicular to the longitudinal axis, the first bladder having a first side and a second side opposite the first side;
• a second bladder extending along the longitudinal axis from a second cuff perimeter segment to the lateral seal, the second bladder having a third side adjacent to the second side of the first bladder, and a fourth side opposite the third side, the fourth side being disposed adjacent to the first side of the first bladder;
• a first port fluidly connected to the first bladder, the first port extending from the first side of the first bladder;
• a second port fluidly connected to the second bladder, the second port extending from the third side of the second bladder;
• a first closure element located between the first perimeter segment and the first port;
• and
• a second closure element located between the second perimeter segment and the second port, wherein:
• the cuff includes
• a third cuff perimeter segment at least partially defining the first and second bladders,
• a fourth cuff perimeter segment opposite the third cuff parameter segment, the fourth cuff parameter segment at least partially defining the first and second bladders,
• the first cuff perimeter segment comprises a first free end of the cuff,
• the second cuff perimeter segment comprises a second free end of the cuff opposite the first free end,
• the third cuff perimeter segment comprises a third free end of the cuff,
• the fourth cuff perimeter segment comprises a fourth free end of the cuff opposite the third free end, and
• the first bladder is fluidly separate from the second bladder.

A method of manufacturing a blood pressure cuff, comprising:

• providing a first sheet of a first material, the first sheet having a first port opening, a first axis extending substantially centrally through the first port opening;
• providing a second sheet of a second material, the second sheet having a second port opening, wherein a second axis extends substantially centrally through the second port opening, and the first material is weldable to the second material;
• providing a third sheet of a third material, the third sheet having a third port opening, a third axis extending substantially centrally through the third port opening;
• providing a fourth sheet of a fourth material, the fourth sheet having a fourth port opening, a fourth axis extending substantially centrally through the fourth port opening;
• providing a first port and a second port;
• forming a perimeter seal segment, the perimeter seal segment sealing the first sheet, the second sheet, the third sheet, and the fourth sheet together such that:
• the first sheet is disposed adjacent to the second sheet,
• the third sheet is disposed adjacent to the first sheet,
• the first axis extends substantially collinear with the third axis,
• the second sheet is disposed adjacent to the fourth sheet, and
• the second axis extends substantially collinear with the fourth axis;
• forming a lateral seal segment, the lateral seal segment that defines a first bladder and a second bladder, wherein:
• the first bladder is bounded laterally by the lateral seal segment and a first portion of the perimeter seal segment opposite the lateral seal segment,
• the second bladder is bounded laterally by the lateral seal segment and a second portion of the perimeter seal segment opposite the lateral seal segment, the first portion of the perimeter seal segment forming a first free end of the cuff, and the second portion of the perimeter seal segment forming a second free end of the cuff opposite and separate from the first free end,
• the first and second bladders are bounded longitudinally by a third portion of the perimeter seal segment and by a fourth portion of the perimeter seal segment opposite the third portion, the third portion forming a third free end of the cuff, and the fourth portion forming a fourth free end of the cuff opposite and separate from the third free end;
• forming a first port seal, the first port seal sealing the first port to the first sheet about a first perimeter of the first port, at least part of the first port extending through the first port opening;
• and
• forming a second port seal, the second port seal sealing the second port to the second sheet about a second perimeter of the second port, at least part of the second port extending through the second port opening.
