Abstract
A blood pressure cuff is defined by a first sheet, having an opening, and a second sheet. The second sheet is attached to a bottom of the first sheet to form an interior inflatable portion between the first sheet and the second sheet, with the opening of the first sheet fluidly interconnecting the interior inflatable portion with an exterior of the cuff. The blood pressure cuff is made from a single type of material and can be recycled, biodegradable, or composted.
Claims18
A method for enabling a blood pressure cuff to conduct measurements, said method comprising:
- providing a blood pressure cuff with an inflatable portion over a portion of the total length of the cuff, the inflatable portion being formed from a first sheet and a second sheet of a fluid impermeable material sealed to one another at respective edges;
- positioning a port in fluid sealing relation to the first sheet within an opening formed in the first sheet on the inflatable portion that provides fluidic interaction with an interior of the inflatable portion, the port having a portion extending outwardly and substantially perpendicularly from an outer surface of the inflatable portion within a plane defined by a length and width dimension of the cuff;
- providing a non-inflatable portion extending over the remainder of the total length of the cuff in which the non-inflatable portion is made from a portion of the first sheet extending from the inflatable portion;
- forming a slotted portion extending through the entire thickness of the non-inflatable portion of the cuff;
- and
- sizing the slotted portion to accommodate the extending portion of the port after the inflatable portion is circumferentially wrapped about the limb of a patient and the non-inflatable portion is circumferentially wrapped over the inflatable portion prior to a blood pressure measurement and wherein the fit between the extending portion of the port and the slotted portion limits the range of limb circumferences to which the cuff can be wrapped.
