Abstract

A cuff for a blood pressure monitor has an air bag inflated/deflated as the air comes in/out. The air bag has an inner wall portion located on the inner side in the fitted state of the cuff and an outer wall portion located outer than the inner wall portion, and a side wall portion connecting side end portions of the inner and outer wall portions and folded inwards in the deflated state of the air bag to form a gusset at each side end portion of the air bag. A bonded portion is provided at a region of the air bag in its winding direction around the living body, for reducing expansion of the gusset formed by the side wall portion. Thus, occurrence of lateral displacement of the cuff is prevented, and a highly reliable blood pressure monitor of high performance can be obtained.

Claims

1. A cuff for a blood pressure monitor having a fluid bag inflated and deflated as a fluid comes in and out, wherein

said fluid bag includes an inner wall portion located, on an inner side in the state where the cuff for a blood pressure monitor is wound around a living body, an outer wall portion located on an outer side than said inner wall portion, and a side wall portion connecting a side end portion of said inner wall portion and a side end portion of said outer wall portion and folded inwards in a width direction of said fluid bag in a deflated state where said fluid bag is not pressurized to thereby form a gusset at a side end portion of said fluid bag, and

a joined portion for reducing expansion of the gusset formed by said side wall portion is provided at a region of the side end portion of said fluid bag in its winding direction around the living body.

2. The cuff for a blood pressure monitor according to claim 1, wherein said joined portion is formed by joining wall surfaces of said side wall portion that would face each other in the state where said side wall portion is folded.

3. The cuff for a blood pressure monitor according to claim 1, wherein said joined portion is formed by joining a wall surface of said side wall portion with a wall surface of said outer wall portion that the wall surface of said side wall portion would face in the state where said side wall portion is folded.

4. The cuff for a blood pressure monitor according to claim 1, wherein said joined portion is formed by joining a wall surface of said side wall portion with a wall surface of said inner wall portion that the wall surface of said side wall portion would face in the state where said side wall portion is folded.

5. The cuff for a blood pressure monitor according to claim 1, wherein said fluid bag further has a connecting portion located between said inner wall portion and said outer wall portion inside said fluid bag and connecting a pair of said side wall portions located at the respective side end portions of said fluid bag.

6. The cuff for a blood pressure monitor according to claim 1, wherein said joined portion is located approximately at a central portion of said fluid bag in its winding direction around the living body.

7. The cuff for a blood pressure monitor according to claim 1, wherein joining in said joined portion is performed by melting and bonding.

8. A blood pressure monitor, comprising:

a cuff for a blood pressure monitor including a fluid bag inflated and deflated as a fluid comes in and out;

an inflating/deflating portion for inflating and deflating said fluid bag;

a pressure detecting portion for detecting a pressure in said fluid bag; and

a blood pressure value calculating portion for calculating a blood pressure value based on pressure information detected by said pressure detecting portion;

wherein

said fluid bag includes an inner wall portion located on an inner side-in the state where said cuff for a blood pressure monitor is wound around a living body, an outer wall portion located on an outer side than said inner wall portion, and a side wall portion connecting a side end portion of said inner wall portion and a side end portion of said outer wall portion and folded inwards in a width direction of said fluid bag in a deflated state where said fluid bag is not pressurized to thereby form a gusset at a side end portion of said fluid bag, and

a joined portion for reducing expansion of the gusset formed by said side wall portion is provided at a region of the side end portion of said fluid bag in its winding direction around the living body.

9. A cuff for a blood pressure monitor having a fluid bag inflated and deflated as a fluid comes in and out, wherein

said fluid bag includes an inner wall portion located on an inner side in the state where the cuff for a blood pressure monitor is wound around a living body, an outer wall portion located on an outer side than said inner wall portion, a side wall portion connecting a side end portion of said inner wall portion and a side end portion of said outer wall portion and folded inwards in a width direction of said fluid bag in a deflated state where said fluid bag is not pressurized to thereby form a gusset at a side end portion of said fluid bag, and a connecting portion located between said inner wall portion and said outer wall portion inside said fluid bag and connecting a pair of said side wall portions located at the respective side end portions of said fluid bag, and

a joined portion is provided at a region of said fluid bag in its winding direction around the living body, said joined portion being formed by joining a wall surface of said connecting portion with a part of a wall surface of said fluid bag located on the side of said inner wall portion or on the side of said outer wall portion when seen from said connecting portion.

10. The cuff for a blood pressure monitor according to claim 9, wherein said joined portion is located approximately at a central portion of said fluid bag in its winding direction around the living body.

11. The cuff for a blood pressure monitor according to claim 9, wherein joining in said joined portion is performed by melting and bonding.

12. A blood pressure monitor, comprising:

a cuff for a blood pressure monitor including a fluid bag inflated and deflated as a fluid comes in and out;

an inflating/deflating portion for inflating and deflating said fluid bag;

a pressure detecting portion for detecting a pressure in said fluid bag; and

a blood pressure value calculating portion for calculating a blood pressure value based on pressure information detected by said pressure detecting portion;

wherein

said fluid bag includes an inner wall portion located on an inner side in the state where said cuff for a blood pressure monitor is wound around a living body, an outer wall portion located on an outer side than said inner wall portion, a side wall portion connecting a side end portion of said inner wall portion and a side end portion of said outer wall portion and folded inwards in a width direction of said fluid bag in a deflated state where said fluid bag is not pressurized to thereby form a gusset at a side end portion of said fluid bag, and a connecting portion located between said inner wall portion and said outer wall portion inside said fluid bag and connecting a pair of said side wall portions located at the respective side end portions of said fluid bag, and

a joined portion is provided at a region of said fluid bag in its winding direction around the living body, said joined portion being formed by joining a wall surface of said connecting portion with a part of a wall surface of said fluid bag located on the side of said inner wall portion or on the side of said outer wall portion when seen from said connecting portion.
