Abstract:
1. A method of producing a cuff of a sphygmomanometer comprising an automatic cuff winding mechanism, wherein the cuff comprises a band-shaped fluid bladder foiming a cavity for insetting a user's arm therein, a shape maintenance member wound on the band-shaped fluid bladder, a band-shaped bag wound on the shape maintenance member, and a cylindrical elastic plate housed in the band-shaped bag, the method comprising: winding the band-shaped fluid bladder on an outer circumferential surface of a cylindrical jig comprising approximately a same outer diameter as the cavity of the band-shaped fluid bladder such that an inner circumferential surface of the band-shaped fluid bladder follows the outer circumferential surface of the cylindrical jig, winding the shape maintenance member on an outer circumferential surface of the band-shaped fluid bladder; winding the band-shaped bag on an outer circumferential surface of the shape maintenance member; removing the cylindrical jig from the band-shaped fluid bladder; and housing, after removing the cylindrical jig, the cylindrical elastic plate inside the band-shaped bag.
