Abstract

With the blood pressure meter of the present invention, a pump unit is connected via a first fluid path to a fluid bladder. The first fluid path extends straight in the Z direction between the pump unit and the fluid bladder, sends air supplied from the pump unit to the fluid bladder or sends air inside of the fluid bladder to a valve.

Claims

1. A blood pressure meter comprising:

a blood pressure measurement cuff containing a fluid bladder into which a fluid is supplied;

a main body attached in an opposing manner to the blood pressure measurement cuff;

a pump arranged within the main body, capable of supplying a fluid to the fluid bladder; and

a first fluid path that sends fluid from the pump into the fluid bladder, or causes fluid to be discharged from the fluid bladder,

wherein the pump is arranged in a mode in which a fluid discharge opening provided in the pump opposes a fluid supply opening provided in the fluid bladder, and

the first fluid path extends straight between the fluid discharge opening of the pump and the fluid supply opening of the fluid bladder.

2. The blood pressure meter according to claim 1, further comprising:

a pressure sensor arranged within the main body, capable of detecting pressure in the fluid bladder; and

a second fluid path that sends a fluid from the fluid bladder to the pressure sensor,

wherein the second fluid path extends straight between the fluid bladder and the pressure sensor.

3. The blood pressure meter according to claim 2, wherein

the direction in which the first fluid path extends and the direction in which the second fluid path extends are the same.

4. The blood pressure meter according to claim 3, wherein

when the blood pressure measurement cuff is wrapped around a wrist of a measurement subject,

a shift between the first fluid path and the second fluid path is 2 cm or less with respect to the circumferential direction of the wrist.

5. The blood pressure meter according to claim 1, further comprising:

a substrate arranged in the main body, on which a control unit for controlling the blood pressure meter is mounted,

wherein the substrate and the pump are arranged in alignment in a direction orthogonal to the direction in which the first fluid path extends.

6. The blood pressure meter according to claim 5, wherein

the substrate has an approximate L shape and the pump is arranged in the recess of the approximate L shape.

7. The blood pressure meter according to claim 2, further comprising:

a substrate arranged in the main body, on which a control unit for controlling the blood pressure meter is mounted,

wherein the substrate and the pump are arranged in alignment in a direction orthogonal to the direction in which the first fluid path extends.

8. The blood pressure meter according to claim 3, further comprising:

a substrate arranged in the main body, on which a control unit for controlling the blood pressure meter is mounted,

wherein the substrate and the pump are arranged in alignment in a direction orthogonal to the direction in which the first fluid path extends.

9. The blood pressure meter according to claim 4, further comprising:

a substrate arranged in the main body, on which a control unit for controlling the blood pressure meter is mounted,

wherein the substrate and the pump are arranged in alignment in a direction orthogonal to the direction in which the first fluid path extends.

10. The blood pressure meter according to claim 7, wherein

the substrate has an approximate L shape and the pump is arranged in the recess of the approximate L shape.

11. The blood pressure meter according to claim 8, wherein

the substrate has an approximate L shape and the pump is arranged in the recess of the approximate L shape.

12. The blood pressure meter according to claim 9, wherein

the substrate has an approximate L shape and the pump is arranged in the recess of the approximate L shape.
