Abstract

In a method of producing a cuff of a sphygmomanometer having an automatic cuff winding mechanism, the cuff includes a band-shaped fluid bladder forming a cavity for inserting 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 includes winding the band-shaped fluid bladder on an outer circumferential surface of a cylindrical jig having approximately the same outer diameter as the cavity of the band-shaped fluid bladder, 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 the cylindrical elastic plate inside the band-shaped bag.

Claims

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 forming 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 the cylindrical elastic plate inside the band-shaped bag.

2. The method of producing the cuff of the sphygmomanometer according to claim 1, wherein the outer circumferential surface of the band-shaped fluid bladder and an inner circumferential surface of the shape maintenance member are partially bonded with a double sided tape.

3. The method of producing the cuff for the sphygmomanometer according to claim 1, wherein the outer circumferential surface of the shape maintenance member and an inner circumferential surface the band-shaped bag are partially bonded with a double sided tape.

4. The method of producing the cuff for the sphygmomanometer according to claim 1, wherein both lateral side ends of the band-shaped fluid bladder that is wound on the outer circumferential surface of the cylindrical jig are separated by a predetermined distance.

5. A method of producing a sphygmomanometer comprising an automatic cuff winding mechanism, wherein the sphygmomanometer further comprises a main body, a substantially cylindrical shell for inserting a user'"'"'s arm rotatably connected to the main body, and a cuff housed in the cylindrical shell, the method comprising:

winding a band-shaped fluid bladder on an outer circumferential surface of a cylindrical jig comprising approximately a same outer diameter as a 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 a shape maintenance member on an outer circumferential surface of the band-shaped fluid bladder;

winding a band-shaped bag on an outer circumferential surface of the shape maintenance member that is wound on the outer circumferential surface of the band-shaped fluid bladder,

removing the cylindrical jig from the band-shaped fluid bladder;

housing the cylindrical elastic plate inside the band-shaped bag; and

housing the cuff within the substantially cylindrical shell,

wherein the cuff is manufactured by the steps of winding the band-shaped fluid bladder, winding the shape maintenance member, winding the band-shaped bag, removing the cylindrical jig, and housing the cylindrical elastic plate.
