Abstract

PURPOSE:To eliminate a dislocation in a surface direction and to prevent a mismeasurement due to the generation of a sound by providing a tightly fittable film in being mutually contacted to an opposed surface at the time of winding an arm band to measure blood pressure in being wound around the arm of a subject. CONSTITUTION:At the inside of a floating part 20b except for an attaching part 20a of an arm band 20 and the outside in the vicinity of the edge of the attaching part 20a, a plastic film 26, in which a static electricity is charge- sealed, and a film 25 to be tightly fitted after electrically fitted in being mutually contacted with it are bondingly fixed. By such constitution, at the time of winding the floating edge 20b in the outer circumference of the attaching part 20a, the films 25 and 26 are tightly fitted by the work of the static electricity, the dislocation in the surface direction cannot be generated at the time of lowering the pressure in the middle of measuring the blood pressure. Moreover, the surfaces of the films 25 and 26 are smooth, and they do not emit a separation sound by a relative movement. Further, when a surface fastener member 27 is provided in the floating edge 20b, even the floating edge 20b is windingly held in the outer circumference of the attaching part 20a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a blood pressure measurement cuff that is wrapped around the arm of a subject when blood pressure is measured using a blood pressure monitor.

[Prior Art] Various blood pressure monitors are used to measure blood pressure in the human body. For example, a cuff that has a pouch that expands when high-pressure air is pumped is wrapped around the subject's arm, high-pressure air at a predetermined pressure is pumped into the pouch, and then the high-pressure air is gradually exhausted to lower the pressure. , during which time the stethoscope listens to the subject's heart sounds (
A common method for measuring blood pressure is to listen to the heart sounds (or Korotkoff sounds), take the air pressure when the heart sounds can be heard as the systolic blood pressure, and take the air pressure when the heart sounds can no longer be heard as the diastolic blood pressure. In this case, the means to measure and display the air pressure are:
There are mercury column, analog pressure gauge, digital pressure gauge, etc.

Recently, automatic sphygmomanometers have been developed that do not require a stethoscope but have a built-in microphone in the arm cuff, which digitally displays the air pressure detected by the microphone when the heart sounds occur and when they stop, thereby measuring the systolic and diastolic blood pressures. being developed.

FIG. 3 shows an example of this automatic blood pressure monitor. In the figure, the device body 1 includes a display unit 2 that digitally displays air pressure, a power switch 3, a start button 4, and a pressure setting switch 5.
is provided. On the other hand, the cuff 6 has a built-in bag portion (not shown) through which high-pressure air is pumped, and a microphone 7. A rubber tube 8 is connected to the bag portion, and a lead wire 9 is connected to the microphone 7. These rubber tubes 8 and lead wires 9 are connected to a connector insertion port 11 provided in the main body 1 via a connector 10. Further, -g8 of the armband 6 is attached with a folding fitting 12, and the other end of the armband 6 is folded back through this folding fitting 12. When the arm cuff 6 is wrapped around the subject's arm and tightened, the pair of female-shaped and key-shaped hook-and-loop fasteners 13 and 14 provided on the opposing surfaces of the arm cuff 6 are tightly engaged and the arm cuff 6 is tightened. Fix the band 6.

When measuring blood pressure with the automatic sphygmomanometer configured as described above, first set the pressure to a value higher than the subject's normal systolic blood pressure using the pressurization setting switch 5, and then turn on the power switch 3. When you press start button 4, main unit 1
A pump (not shown) inside is driven, and high-pressure air is pumped into the bag portion of the cuff 6 until the set pressure is reached. Next, the pressure starts to decrease and the pressure at which the microphone 7 detects a heart sound is digitally displayed on the display section 2. This value is the systolic blood pressure. When the pressure further decreases and the microphone 7 no longer detects heart sounds, the pressure at that time is digitally displayed on the display section 2. This value is the diastolic blood pressure.

[Problems to be Solved by the Invention] However, according to the conventional blood pressure measurement cuff configured as described above, the hook and loop fasteners 13 and 14 that engage the cuff have a large number of hooks and loops that are continuous in the surface direction. The hooks and loops are engaged with each other.

For this reason, the engagement force in the direction perpendicular to the plane is strong, but the engagement force in the plane direction is weak, and when blood pressure is lowered during blood pressure measurement, the engagement between each hook and loop gradually disengages, producing a minute crunching sound. Occur. When the microphone 6 detects this sound, it becomes difficult to distinguish when the actual heart sound is occurring and when it has stopped.
There was a problem in that errors occurred in the measurement of maximum and diastolic blood pressure. This problem also occurs when heart sounds are detected using a stethoscope.

The present invention has been made in view of the above circumstances, and it is possible to prevent misalignment in the plane direction and prevent erroneous measurements due to sound generation when blood pressure is measured by wrapping it around the arm of a subject. The purpose of this invention is to provide a wristband for measuring blood pressure that can be used to measure blood pressure.

[Means for Solving the Problems] A configuration for achieving the above object will be described with reference to FIG. 1 corresponding to the first embodiment. The blood pressure measurement cuff according to the present invention has a bag portion that is inflated by pumping high-pressure air,
Blood pressure measurement cuff 2 that is wrapped around the subject's arm to measure blood pressure
0, on the opposing surface when the arm cuff 20 is wound,
It is characterized by providing films 25 and 26 that can be closely attached to each other. This film 25, 26 may be made of electrostatically charged plastic or may be an adhesive tape. Moreover, a locking/disengaging means such as a hook-and-loop fastener member 27 or the like that can be engaged with the outer surface may be provided on the inner surface of the free end portion 20b of the arm cuff 20 configured as described above.

[Function] According to the above configuration, when the arm cuff is wrapped around the subject's arm, the close contact portions of the films 25 and 26 are in close contact with each other in the plane direction, and the bonding portion has an even and strong bonding force. Therefore, the engagement does not disengage when the blood pressure decreases or increases during blood pressure measurement, and there is no sound generated due to engagement separation as in the past.
This can prevent erroneous measurements.

[Example] Hereinafter, an example of the arm cuff for blood pressure measurement according to the present invention will be described with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention. The arm cuff 20 is made of a fabric material 21 that has a large number of loop-like soft naps on both sides.
A mounting part 20 formed of
a has a double structure. An unillustrated base material made of an elastic plastic member having a substantially arc-shaped cross section is enclosed in the inner outer circumferential side of the mounting portion 20a, and the inner circumferential side is expanded by high-pressure air. A bag not shown is enclosed. A microphone 7 is provided inside the mounting portion 20a, a lead wire 9 is connected to the microphone 7, a rubber tube 8 is connected to the bag portion, and the lead wire 9 is connected to the rubber tube 8. It is wound around the outer circumference and held. These lead wires 9 and rubber tube 8 are connected to the main body 1 of the apparatus in the same manner as in the conventional example shown in FIG. Also armband 2
On the inside of the free end portion 20b other than the mounting portion 20a of 0, and on the outside near the end of the mounting portion 20a, a plastic film 26 charged with static electricity is electrodeposited and closely adhered to the plastic film 26 filled with static electricity. A flexible film 25 is adhesively fixed to the free end portion 20b, and on the surface of one end of the film 25, a hook and loop fastener member 27 having a large number of loop portions that engage with the naps of the cloth material 21 is provided. Fixed with adhesive.

Next, the operation of the first embodiment will be explained. The blood pressure measurement method is the same as the conventional example described above. Attachment part 20 of arm cuff 20
A is attached to the subject's arm, and the free end 20b is attached to the attachment part 20a.
When wound around the outer periphery of the membrane, the films 25 and 26 are brought into close contact with each other by the action of static electricity, and will not shift in the plane direction when the blood pressure is lowered during blood pressure measurement. Moreover, since the surfaces of the films 25 and 26 are smooth and do not have uneven engaging parts unlike hook-and-loop fasteners, there is no separation sound caused by relative movement. Further, since the free end portion 20b is locked by the engagement between the hook and loop fastener member 27 and the cloth material 21, the free end portion 20b is also secured to the mounting portion 20.
It is wound and held around the outer circumference of a. At this time, since the mounting portion 20a and the free end portion 20b are prevented from shifting in the plane direction through the films 25 and 26, no sound is generated when the pressure is lowered or increased. It is possible to prevent erroneous measurements caused by noise caused by displacement of the cuff 20 during blood pressure measurement.

FIG. 2 is a perspective view of a cuff 120 according to a second embodiment of the invention. This arm cuff 120 uses a folding metal fitting 12 similar to the conventional example shown in FIG. Films 125 and 126 are provided which can be brought into close contact with each other by electrostatic action.

In the first and second embodiments described above, a case has been described in which the wristband is closely held through a plastic film charged with static electricity, but instead of using a plastic film, it is possible to prevent the occurrence of deviation in the plane direction. Other members, such as adhesive tape, may also be used. Furthermore, the hook-and-loop fastener member 27 of the first embodiment may be omitted, and other engaging/disengaging means such as hooks may be used. Further, in the above embodiment, the case of a digital automatic blood pressure monitor using the microphone 7 as a means for detecting heart sounds has been explained, but the wrist cuff according to this embodiment may also be used in a digital automatic blood pressure monitor using a stethoscope or an analog display blood pressure monitor. A similar effect can be obtained.

[Effects of the Invention] As explained above, according to the blood pressure measurement arm cuff according to the present invention, films that can be brought into close contact with each other are provided on the opposing surfaces when the arm cuff is wound. Alternatively, no sound is generated during the step-down, and there is an effect that erroneous measurements due to the generation of sound can be prevented.
