JP5800743B2 - Sphygmomanometer cuff and sphygmomanometer - Google Patents

Description

The present invention relates to a sphygmomanometer cuff and a sphygmomanometer.

A typical sphygmomanometer cuff contains an air bag that can inject and discharge air inside the band, wraps the band around the upper arm near the heart, covers the artery inside the upper arm with an air bag, and measures blood pressure To do.
Conventionally, an annular fastener is attached to one end of the band, and an engagement tool such as a hook-and-loop fastener is attached to the outer surface of one end of the band so that the person to be measured can wrap the band around the upper arm by himself / herself. A sphygmomanometer cuff is known.

To attach the sphygmomanometer cuff to the upper arm, the other end of the band is inserted into a fastener to make the band into a ring shape, the upper arm is passed through the ring-shaped band, and then the other end folded back is pulled to the band. Is adjusted to the thickness of the upper arm, and the engaging tool is engaged with the outer surface of the band to tighten the upper arm.
Since the position of the folded portion of the band varies depending on the thickness of the upper arm portion, the air bag that cannot be folded is usually built in one end side of the band.

  The conventional sphygmomanometer cuff includes a clamp having first and second clamping members, and a band having one end fixed to the first clamping member, and includes a first clamping member and a second clamping member. By folding the other end of the band between the fastening members and attaching the coating material attached to the outer surface of one end of the band to the coating material attached to the outer surface of the second fastening member, the band is attached. There is one that wraps around the upper arm (see Patent Document 1).

In addition, an air bag is provided on one end side of the band body, a retaining ring is inserted through which the other end portion of the band body is inserted and folded, and the other end portion of the band body that is folded back is locked to the outer surface of the band body. An arm band of a sphygmomanometer provided with locking means is also known (see Patent Document 2).
In this arm band, one end of the band is extended from the retaining ring attachment portion (the folded portion at the other end) to form an overlapping portion, and the air bag is extended to this overlapping portion. When the belt is mounted on the arm so as to be positioned at the position, the direction in which the other end of the belt is pulled is downward on the body side, so that it can be attached with a natural posture without difficulty.

Each of the inventions of Patent Document 1 and Patent Document 2 has a problem that the cuff cannot be wound around various arm shapes. For example, in the case of a person with a tight upper arm cone, a band may be inserted obliquely into the tightening member, but this is not possible.
An object of the present invention is to provide a sphygmomanometer cuff and a sphygmomanometer capable of winding a cuff corresponding to various arm shapes.

In order to solve the above problems, the sphygmomanometer cuff of the present invention attaches one member of a fastener to the outer surface of the band to be wound around the upper arm portion when wound, and is one end portion of the band inside the upper arm portion. A bag body that can inject and discharge air is housed inside the wound portion, and a cylindrical buckle into which the other end of the band is slidably inserted is attached to the outer surface of the one end of the band, The other member of the fastener is attached to the outer surface of the buckle, the other end portion of the band is inserted into the buckle and then folded back, and the other end portion of the band is fastened to the outer surface of the buckle via the fastener.
The fastener may be a hook and loop fastener, and a loop member may be attached to the outer surface of the band over the entire length, and a hook member may be attached to the outer surface of the buckle.

On the outer surface of the band, a ring that is slidably inserted into the other end of the band and folds is attached to the buckle slightly closer to the other end.
In this case, an elastically deformable reinforcing sheet may be attached from the attachment position of the buckle to the attachment position of the ring on the outer surface side of the bag body inside the one end portion of the band.

  According to the present invention, since one end of the cuff with respect to the buckle can also be inserted obliquely, it is possible to correspond to various arm shapes and to measure accurate blood pressure.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 4, the sphygmomanometer cuff 1 of the present invention includes a band 2, a bag body 3 housed inside the band 2, a buckle 4 attached to one end of the band 2, and a buckle A ring 5 attached to the band 2 is provided slightly closer to the other end (inner peripheral side) than 4.
The band 2 is a band-shaped member having a length of about 50 cm so as to be wound around the upper arm portion a (FIG. 2) that is a measurement site of the measurement subject. Is formed into a flat bag shape.

The width of one end side of the band 2 is about 14 cm, and the width of the portion extending about 15 cm from the other end is slightly narrowed to about 12 cm (FIGS. 3 and 4).
As shown in FIGS. 1 and 3, a loop member of a hook and loop fastener 8, which is an engaging member, is provided on the outer surface of the band 2 (the outer surface of the front fabric 6) that is outside when the band 2 is wound around the upper arm portion a. 8a is mounted over almost the entire surface. The loop member 8a is attached to the front fabric 6 by sewing, bonding or the like.

  Further, as shown in FIGS. 3 and 4, at the other end of the band 2, a rod-shaped member that serves as a stopper 9 is attached between the front fabric 6 and the back fabric 7 along the width direction of the band 2. Yes. As shown in FIG. 1, the bag body 3 is a flat bag having a width slightly narrower than one end side of the band 2 and having a length of about ½ of the entire length of the band 2. It is installed between the front fabric 6 and the back fabric 7. Further, the front fabric 6 and the back fabric 7 are sewn near the other end of the bag body 3, and the bag body 3 is attached to the band 2 so as not to move.

The bag body 3 has an air supply / exhaust port 10 protruding from the outer surface of the band 2, and a pump of a blood pressure monitor main body (measurement unit) (not shown) via a tube 14 (FIG. 6) fitted to the air supply / exhaust port 10. It is connected. And by operating a pump, air can be inject | poured or discharged | emitted in the inside of the bag body 3. FIG.

A reinforcing sheet 11 is attached between the bag body 3 and the front fabric 6 from the attachment position of the buckle 4 to the attachment position of the ring 5.
The reinforcing sheet 11 is made of an elastically deformable thin plate made of polypropylene or the like. The reinforcing sheet 11 is bent in accordance with the shape of the upper arm portion a when the band 2 is wound, and is bent in accordance with the shape of the bag body 3 that expands when air is injected into the bag body 3, but the air is discharged from the bag body 3. When the band 2 is removed from the upper arm part a, the original shape is restored.

The buckle 4 is made of a relatively hard and strong synthetic resin such as ABS resin, and is formed in a flat cylindrical shape having substantially the same width as one end of the band 2.
Further, the buckle 4 is attached to the outer surface of the outer fabric 6 (the outer surface when the band 2 is wound and the outer surface of the loop member 8a) so that the axial direction thereof coincides with the long axis of the band 2. .

As shown in FIG. 5, the outer piece 4a of the buckle 4 is inclined so that the height of the internal space gradually increases from the other end toward the one end. Further, in the longitudinal direction of the band 2, one end portion of the outer piece 4 a of the buckle 4 extends longer than one end of the inner piece 4 b attached to the band 2 and serves as a guide portion 12.
This guide portion 12 makes it possible to easily cope with the case where the band 2 is inserted obliquely with respect to the buckle 4. That is, it has become possible to easily deal with various types of measurement subjects such as measurement subjects with thick arms and measurement subjects with a shape of the upper arm which is a measurement site (conical shape).

As shown in FIGS. 1 to 3, a hook member 8 b of a hook and loop fastener 8 is attached to the outer surface of the buckle 4.
The hook member 8b preferably has an area covering at least half of the outer surface of the buckle 4 so that the other end of the band 2 can be securely attached. The outer piece 4a of the buckle 4 is formed by welding, sewing, or the like. It is firmly fixed to.

The ring 5 is formed by bending a thin round bar made of metal which is not easily rusted into an elongated ring shape, and has a long diameter slightly larger than the width of the other end portion of the band 2.
In addition, a loop piece 13 formed by folding a belt-like cloth half-width is sewn along the width direction of the band 2 on the outer surface of one end of the band 2 slightly closer to the other end than the buckle 4. The side is inserted into the loop piece 13.
Therefore, the ring 5 attached to the outer surface of the band 2 via the loop piece 13 can swing in the one end direction and the other end direction of the band 2.

To attach the sphygmomanometer cuff 1 to the upper arm a, the other end of the band 2 is inserted into the buckle 4 and the ring 5 as shown in FIG. The upper arm part a is passed through the ring-shaped band 2 so as to face the side.
Since the outer piece 4a of the buckle 4 is inclined and the guide portion 12 is formed at one end portion of the outer piece 4a, the other end portion of the band 2 can be easily inserted into the buckle 4. Further, since the stopper 9 is provided at the other end of the band 2, after the other end of the band 2 is once passed through the ring 5, it can be removed from the ring 5 and the buckle 4 unless forcibly pulled out. There is no.

Next, as shown in FIG. 2, the other end of the band 2 is placed with the central portion of the bag 3 (the portion slightly spaced from one end of the band 2) aligned with the vicinity of the artery b inside the upper arm. Fold from the position of the ring 5 and pull downward on the body side.

At this time, since the folded portion of the band 2 is supported by the ring 5, the inner surface of the band 2 is not lifted from the inner peripheral surface of the buckle 4 and rubbed strongly, and the ring 5 made of a thin round bar is pulled. Since it swings according to the force, the frictional force applied to the outer surface of the band 2 is also reduced.
Then, after adjusting the diameter of the ring-shaped band 2 to the thickness of the upper arm part a, the outer surface of the other end of the folded band 2 is pressed against the outer surface of the buckle 4 as shown in FIG. The loop member 8a and the hook member 8b are engaged.

  Since the hook member 8b is attached to the outer surface of the buckle 4 protruding from the outer surface of the band 2, the other end of the band 2 can be easily fixed to the outer surface of the buckle 4 simply by pressing the band 2 lightly.

A fastener other than a hook and loop fastener can be used as long as it can be attached and detached by operating with one hand. However, the loop member 8a attached to the outer surface of the belt 2 over the entire length, and the outer surface of the buckle 4 The hook and loop fastener 8 including the hook member 8b attached to the head is not only easy to attach and detach, but can also cope with differences in the thickness of the upper arm portion of the measurement subject.
Further, the shape of the buckle 4 and the attachment structure of the ring 5 are not limited to the above-described embodiments.
