Abstract

A blood pressure information measurement device cuff includes a wide blood pressure value measurement air bladder wrapped around a fitting area when in a fitted state, and a narrow pulse wave measurement air bladder disposed so as to be closer to the fitting area than the blood pressure value measurement air bladder when in the fitted state, and covered by the blood pressure value measurement air bladder when wrapped around the fitting area. The pulse wave measurement air bladder includes an anchored portion anchored to the blood pressure value measurement air bladder so as to be immobile relative to the blood pressure value measurement air bladder and a mobile portion that is not anchored to the blood pressure value measurement air bladder so as to be mobile relative to the blood pressure value measurement air bladder along a wrapping direction in which the cuff is wrapped around the measurement area.

Claims

1. A blood pressure information measurement device cuff that takes on a ring-shaped state when wrapped around a fitting area in a fitted state, the cuff comprising:

a wide first fluid bladder that is wrapped around the fitting area when in the fitted state; and

a narrow second fluid bladder disposed so as to be closer to the fitting area than the first fluid bladder is when in the fitted state and that is covered by the first fluid bladder when wrapped around the fitting area,

wherein the second fluid bladder comprises an anchored portion that is anchored to the first fluid bladder so as to be immobile relative to the first fluid bladder and a mobile portion that is not anchored to the first fluid bladder so as to be mobile relative to the first fluid bladder along a wrapping direction in which the cuff is wrapped around a measurement area.

2. The blood pressure information measurement device cuff according to claim 1,

wherein the first fluid bladder is, when in the fitted state, wrapped around an area of the fitting area that comprises both a center area and peripheral areas of the fitting area, and

wherein the second fluid bladder is, when in the fitted state, wrapped around an area of the fitting area that comprises only the center area of the fitting area.

3. The blood pressure information measurement device cuff according to claim 1, further comprising:

a guidance portion that guides a movement of the mobile portion along the wrapping direction.

4. The blood pressure information measurement device cuff according to claim 1, further comprising:

a vibration blocking portion, disposed between the first fluid bladder and the second fluid bladder, that prevents vibrations produced in the first fluid bladder from being transmitted to the second fluid bladder and that prevents vibrations produced in the second fluid bladder from being transmitted to the first fluid bladder.

5. The blood pressure information measurement device cuff according to claim 1, further comprising:

a guidance member that guides the movement of the mobile portion along the wrapping direction; and

a vibration blocking member, disposed between the first fluid bladder and the second fluid bladder, that prevents vibrations produced in the first fluid bladder from being transmitted to the second fluid bladder and that prevents vibrations produced in the second fluid bladder from being transmitted to the first fluid bladder,

wherein the guidance member and the vibration blocking member are both configured of a nonwoven material formed into a band shape, and

wherein the vibration blocking member is disposed between the first fluid bladder and the second fluid bladder and is anchored to the first fluid bladder, the guidance member is overlaid upon the vibration blocking member so as to cover at least part of the second fluid bladder and is anchored to the vibration blocking member, and the movement of the mobile portion along the wrapping direction is guided by inserting at least part of the mobile portion into a channel defined by the vibration blocking member and the guidance member.

6. The blood pressure information measurement device cuff according to claim 5,

wherein the entirety of the mobile portion is inserted into the channel.

7. The blood pressure information measurement device cuff according to claim 5,

wherein an end of the mobile portion located on an opposite side as the anchored portion is disposed having been led out from the channel.

8. The blood pressure information measurement device cuff according to claim 5,

wherein the anchored portion is formed by anchoring one end of the second fluid bladder to the first fluid bladder via the vibration blocking member.

9. The blood pressure information measurement device cuff according to claim 8,

wherein the anchoring of the vibration blocking member to the first fluid bladder, the anchoring of the guidance member to the vibration blocking member, and the anchoring of the second fluid bladder to the vibration blocking member are all carried out through welding.

10. The blood pressure information measurement device cuff according to claim 1,

wherein the anchored portion is located at one end of the second fluid bladder in a lengthwise direction thereof.

11. The blood pressure information measurement device cuff according to claim 10, further comprising:

an outer cover that contains the first fluid bladder and the second fluid bladder,

wherein of two ends of the outer cover in the wrapping direction, the anchored portion is disposed on one of the two ends that is located toward the fitting area when the cuff is in the fitted state.

12. The blood pressure information measurement device cuff according to claim 1,

wherein the anchored portion is located in approximately the center of the second fluid bladder in a lengthwise direction thereof.

13. A blood pressure information measurement device comprising:

the blood pressure information measurement device cuff according to claim 1.
