Abstract

A cuff for a blood pressure monitor is wound around a measurement site of the living body, and includes an air bag having an inflated/deflated space formed therein by melting and bonding rims of an outer wall portion and an inner wall portion together. The air bag contains a band-shaped connecting portion, which has ends respectively attached to one end and the other end of the air bag in its winding direction around the living body, so as to extend substantially continuously from the one end to the other end of the air bag. The band-shaped connecting portion is arranged inside the inflated/deflated space of the air bag. With this configuration, a cuff for a blood pressure monitor permitting uniform inflation of the air bag over the entire region when the pressurized air is introduced therein is obtained.

Claims

1. A cuff for a blood pressure monitor wound around a living body, comprising a fluid bag having an inflated/deflated space permitting a fluid to come in/out formed therein by joining rims of sheet-shaped members laid one on another, wherein

said fluid bag includes a band-shaped connecting portion arranged inside said inflated/deflated space, said band-shaped connecting portion extending substantially continuously from one end to the other end of the fluid bag in a winding direction along which the fluid bag is wound around the living body, and having ends respectively attached to said one end and said other end of said fluid bag.

2. The cuff for a blood pressure monitor according to claim 1, wherein a plurality of said band-shaped connecting portions are arranged inside said inflated/deflated space.

3. The cuff for a blood pressure monitor according to claim 1, wherein

said sheet-shaped members and said band-shaped connecting portion are formed of resin materials that can be melted and bonded together, and

joining of the rims of said sheet-shaped members and attaching of said band-shaped connecting portion to said fluid bag are carried out by melting and bonding the rims of said sheet-shaped members and said band-shaped connecting portion together in an integral manner.

4. The cuff for a blood pressure monitor according to claim 1, wherein

said sheet-shaped members and said band-shaped connecting portion are formed of a same resin material, and

joining of the rims of said sheet-shaped members and attaching of said band-shaped connecting portion to said fluid bag are carried out by melting and bonding the rims of said sheet-shaped members and said band-shaped connecting portion together in an integral manner.

5. The cuff for a blood pressure monitor according to claim 1, wherein

said fluid bag includes an inner wall portion positioned on an inner side and an outer wall portion positioned on an outer side in a fitted state of the cuff,

said sheet-shaped members are configured with a first resin sheet having said band-shaped connecting portion and one of said inner wall portion and said outer wall portion, and a second resin sheet having the other of said inner wall portion and said outer wall portion, and

said fluid bag is formed by folding the first resin sheet, laying the first resin sheet on the second resin sheet, and by melting and bonding rims of the first and second resin sheets together.

6. The cuff for a blood pressure monitor according to claim 1, wherein

said fluid bag includes an inner wall portion positioned on an inner side and an outer wall portion positioned on an outer side in a fitted state of the cuff,

said sheet-shaped members are configured with one resin sheet having said inner wall portion, said outer wall portion and said band-shaped connecting portion, and

said fluid bag is formed by folding the resin sheet such that said inner and outer wall portions are laid one on another, with said band-shaped connecting portion arranged therebetween, and by melting and bonding rims of said inner and outer wall portions of the resin sheet together.
