[Background technology]

A sphygmomanometer equipped with a cuff band containing an air bag for ischemia and a microphone detects arterial blood pulse sounds, that is, Korotkoff sounds, using the microphone, and the cuff band is wrapped around the upper arm of the human body. It is important that the microphone is placed accurately in the brachial artery when
If the microphone is not placed precisely in the brachial artery, it will not be possible to measure the correct blood pressure value. The cuff band of a conventional blood pressure monitor is shown in FIG. 1, for example.

The surface of the attachment part 7 that is wrapped around the upper arm 6 of the human body,
A mark 31 was pasted at a position corresponding to the upper part of the microphone, and the cuff band 1 was wrapped so that the mark 31 was at the position of the brachial artery. However,
The brachial artery ratio is the point where you can feel the pulsation by pressing your finger on the little finger side of your arm, just above the elbow joint.For some people, the pulsation is weak and it may be difficult to locate it, and the cuff band 1
When wrapping the brachial artery, you must first confirm the position of the brachial artery and then adjust it to the position of the artery.
This method largely relies on the visual judgment and intuition of the person being measured, and it requires practice and skill to place the microphone accurately and quickly at the brachial artery, making it extremely difficult for those with little experience.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to eliminate the need to search for the location of the brachial artery.
To provide a cuff band for a blood pressure monitor, which allows a microphone to be accurately and quickly placed in the brachial artery without requiring any experience or skill, and which can be easily wrapped.

[Disclosure of the Invention] Hereinafter, embodiments of the present invention will be described based on FIGS. 1 is a cuff belt, which is attached to the upper arm of a human body. The width of the binding part 8 is narrower than the width of the attachment part 7. One of the fasteners 9 of the planar fastener is attached to the surface of the distal end of the attachment part 7, and the other fastener 10 of the planar fastener is attached to the back surface of the binding part 8 in the longitudinal direction. When the attachment part 7 is temporarily wrapped around the upper arm part 6, the cuff can be secured by wrapping the cuff band part 8 in the winding direction of the cuff band 1 and attaching and tying it with the fastening devices 9 and 10. The band 1 can be wrapped around the upper arm 6. The binding band portion 8 has two outer cloth sides, 13
The attachment part 7 is constructed by pasting together the binding part 8.
A series of two outer cloths ν.

By heat-sealing the periphery of the sum, it is constructed into a closed bag shape. The mounting portion 7 accommodates a curved plate, an air bag for ischemia 5, and a microphone 21, and the entire mounting portion 7 is curved. A sheet 14 is arranged on the outside of the inner outer cloth opening of the two outer cloth branches 13, and the sheet 14 is heat-sealed to the inner outer cloth so that it can be used for ischemia. The air bag 5 is configured by the two outer cloths V,
An elastic curved plate made of nylon or the like is built in between the outer side of the 13 and the seat 14, and this prevents the mounting part 7 from being subjected to external force as shown in FIG. An opening 3 into which the upper arm part 6 is inserted is formed between both ends of the mounting part 7.

A mechanical γ-pipe 29 for supplying and discharging pressurized air is connected to the ischemic air bag 5.
is the end face in the transverse direction of the mounting part 7, and includes two outer fabric strips, 1
3 is led out to the outside through an opening 28 formed by a portion not heat-sealed, and is connected to a pressure pump (not shown). A bag-shaped storage section 22 that is open at the end surface in the transverse direction of the mounting section 7 is formed in the inner outer retainer, and a microphone 21 is stored in the storage section 22. The storage section 22 is formed at a position offset from the longitudinal center of the mounting section 7 in the distal direction of the mounting section 7,
Thereby, when the cuff band 1 is wrapped around the upper arm part 6, the microphone 21 is made to substantially match the position of the brachial artery m. Here, the microphone 21 is fixed in the storage section 22 to a position layer spaced approximately 35 meters apart in the lateral direction of the mounting section 7 from the lateral end surface into which the upper arm of the mounting section 7 is inserted. A shielded wire 30 is connected to the microphone 21, led out from the opening 23 of the storage section 22, and connected to the main body of the blood pressure monitor (not shown). The surface of the mounting portion 7, where the microphone 2
A ring-shaped mark 31 is located at a position corresponding to the top of 1.
Further, an instruction manual 32 on how to wrap the cuff band is attached to approximately the center in the longitudinal direction of the mounting portion 7. Storage section 22 of the mounting section 7
A pair of protruding pieces 33. is made to protrude from the end surface in the transverse direction of the side having the opening 23. ! 14, and the pair of protrusions 3B and 34 are arranged on both sides of the cuff band 1 in the longitudinal direction with the microphone 21 at the center, respectively, at a constant interval from the microphone 21 to the cuff band 1 in the longitudinal direction. It is placed in a space between the two. Here, the location of the brachial artery ratio is generally.

When the arm is extended, it is about 35 fl from the slightly concave part found at the center of the inside of the elbow, the so-called cubital fossa ν.
It is said that the electric current is approximately 40111 points above the inside of the arm, and this has been confirmed by actual measurements. From the above point, the pair of protrusions 33 and 34 each extend from the microphone 21 to the cuff band 1.
The microphone 21 is disposed at a position approximately 40w1 apart in the longitudinal direction of the mounting part 7, and as described above, the microphone 21 is disposed at a position 35m apart in the lateral direction of the mounting part 7 from the lateral end surface of the mounting part 7. ing. With this, with the attachment part 7 of the cuff band 1 temporarily wrapped around the upper arm part 6, one of the pair of protrusions BB and 84 is aligned with the counter current of the elbow,
By placing the microphone 21 on the inside of the arm, the microphone 21 is placed accurately at the brachial artery. Of the pair of protrusions 3B and 34, one of the protrusions 34, which is located toward the distal end of the mounting portion 7 with the microphone 21 sandwiched between them, has the letters on the left written on its surface, and the letters on the left are written on the surface of the other protrusion 33. has the characters on the right written on it.

This is so that when the projecting pieces 3m and 34 are aligned with the counter electrode 17, the microphone 21 is located inside the upper arm portion 6, that is, at the position of the brachial artery.

Next, the procedure for wrapping the cuff band of the pressure gauge according to the present invention around the upper arm will be explained with reference to FIGS. 4 and 5. When wrapping the cuff 1 around the right upper arm, insert the right upper arm 24 through the opening 3 of the attachment part 7 of the cuff 1, as shown in FIG. Align the protruding piece 33 with the counter electrode 17 of the cloth material. As a result, the microphone 21 is placed accurately with the right brachial artery number, and the strap part 8 is wound in the winding direction of the cuff belt 1, and the anchoring device 9. By attaching and tying the IO, the cuff band 1 is wrapped around the right upper arm portion 24. The same goes for wrapping the cuff band 1 around the left upper arm.As shown in Fig. 21 is placed precisely on the left brachial artery. If you wrap the cuff band 1 with one palm facing upward and your arm extended, you can easily check the position of the counter electrode 17, and more accurately and easily wrap the cuff band 1 on the upper arm. Can be wrapped.

〔Effect of the invention〕

As described above, one aspect of the present invention is a cuff band for a blood pressure monitor that houses an air bag for ischemia and a microphone, and is wound around the upper arm in the longitudinal direction, the cuff band being separated from the microphone for a certain length of time in the longitudinal direction of the cuff band. Since the protruding piece is provided at the position where the cuff band is located and protruding from the end surface in the transverse direction of the cuff band, there is no need to search for the position of the brachial artery, and the protruding piece can be aligned with the inner corner of the elbow.

The microphone can be placed accurately and quickly in the brachial artery simply by simply using the device, and the wrapping can be easily and quickly done without requiring any experience or skill.
