  • Patent number: 4844306
    Abstract: A harness is provided for holding a blood pressure cuff in the correct position on the arm when being worn for extended periods of time. The harness has a support member that attaches by clasps directly to the cuff on the person's arm. The support member extends from the cuff to the shoulder region of the user so that the weight of the cuff is carried by the shoulder rather than by the arm through contact pressure from the cuff itself. The support member prevents slippage or rotation of the cuff throughout the monitoring period. A strap is provided that attaches to the support member at the shoulder region and runs under the other arm of the user to hold the support member in the correct position.

  • Patent number: 4832040
    Abstract: A self-adjusting blood pressure cuff assembly. A cinch ring at the fixed end of the blood pressure cuff assembly has at least one lateral extension disposed away from the direction of the fixed end of the flexible belt of the cuff assembly. The longitudinal extension has two longitudinally directed sides. Placing reinforcing stitches closely adjacent the longitudinally directed sides substantially restricts transverse movements of the cinch ring with respect to the flexible band. In a preferred embodiment, a tag piece, passing through the slot of the cinch ring and covering the lateral extension, is reinforced stitched to the outward cover of the elongated flexible band of the blood pressure cuff assembly. In this way, an end of an inflatable bladder can be caused to be adjacent to the loop of material forming the fixed end of the flexible band.

  • Patent number: 4745924
    Abstract: A blood pressure cuff particularly for use with ambulatory blood pressure products and suitable for use in either the left or right limbs of the patient is disclosed. The cuff includes an elongated, flexible band having a body side face and an outward face and a compartment. It further includes an inflatable bladder having a centerline and adapted for placement within the compartment in either a first position or a second position rotated 180.degree. from the first position. The bladder includes a portion coupled on one side of the centerline and adapted to protrude through an opening in the band when the bladder is in either the first or second position. The opening comprises two separate openings on either side of the centerline. First and second indicia placed adjacent the openings on the outward face of the band identify the position of the protruding portion for use on either the left or right side limb.

  • Patent number: 4727885
    Abstract: A self applied blood pressure cuff particularly for use with ambulatory blood pressure products and suitable for use on either the left or right limbs of the patient is disclosed. The cuff includes an elongated, flexible band having a body side face and an outward face and a compartment. It further includes an inflatable bladder having a portion adapted to protrude through one of two openings in the band when the bladder is on either the left or right arm. The two openings are located opposite one another on opposite lengthwise edges of the band. First and second indicia placed adjacent the openings on the outward face of the band identify the position of the protruding portion for use on either the left or right arm.
