BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable blood pressure measuring device which can be easily used in hospitals and homes.

[0002]

2. Description of the Related Art Conventionally, a sphygmomanometer using a mercury column has been used for many years. In this mercury sphygmomanometer, the upper arm is tightened with an arm band (cuff), then slowly relaxed, and the measurement is performed while listening to the pulse sound by applying a stethoscope to the back of the elbow.
The pressure at the moment when the blood flow of the stopped artery resumes and the pulsating sound starts to be heard is “systolic blood pressure”, and the blood pressure at the moment when the artery is completely expanded and the pulsating sound disappears is “diastolic blood pressure”. There are also various electronic blood pressure measuring devices as devices of this measuring method.

[0003]

However, in the case of using the above-mentioned mercury column, since the cuff and the main body of the instrument are separated, not only the operation is complicated, but also the operation is complicated. Requires a great deal of labor to transport. Also, in the electronic type, as in the case of using the mercury column, the cuff and the main body of the instrument are separated, so that the measurement start state cannot be obtained immediately. There was a problem that it took time to remove the cuff. For this reason, it is also a major cause of heavy labor and long working hours for nurses and the like, which has become a problem in recent years.

[0004] In addition, all of the above-mentioned ones have a problem that a bedridden patient or the like cannot perform measurement in a reasonable posture.

Accordingly, an object of the present invention is to provide a portable blood pressure measuring device that can be easily used in hospitals and homes.

[0006]

According to the present invention, there is provided a portable blood pressure measuring device in which a compression / decompression member and an instrument main body for detecting and displaying blood pressure are integrated.
A grip for gripping is provided at a position on the upper surface side of the instrument main body in parallel with a direction in which the pressurizing / depressurizing member is inserted into the upper arm of the cylindrical space.

[0007]

The portable blood pressure measuring device according to the present invention grips the grip provided on the main body of the instrument, and inserts the upper arm in the extension direction of the grip while holding the grip, so that the upper arm is added. It is inserted into the cylindrical space of the pressure reducing member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described below with reference to the drawings.

(First Embodiment) A portable blood pressure measuring device 1 according to a first embodiment is shown in FIGS.
As shown in FIG. 2, the instrument body 2 includes a pressure increasing / decreasing member 3 and a grip 4 for gripping, and the instrument body 2 is further provided with a release lever 10.

The instrument main body 2 is provided with a group of various operation buttons 5 and a display section 6 for displaying a measurement result of blood pressure on the upper surface 2a. Although not specifically shown, the inside of the instrument main body 2 is configured so that a pressure pump / pressure sensor can pressurize or depressurize a pressure-decompressing / depressurizing member 3 described later based on a command from a central processing unit (CPU). It has been done. Also,
An exhaust valve is provided, and when the blood pressure measurement ends, C
The pressurizing and depressurizing member 3 is evacuated based on the PU command. Further, the pressure sensor is configured to detect pressurization of the pressurizing / depressurizing member and to display the pressure on the display unit 6.

An underside of the instrument main body 2 is provided with an arc-shaped fixing portion 8, and an insertion hole through which the pressurizing / depressurizing member 3 is inserted is provided on one side 8 a of the fixing portion 8 on the arc. 9
Are formed (see FIGS. 2 and 3).

The instrument body 2 has one side 2b.
Is provided with a release lever 10. This release lever 1
Numeral 0 is formed on one side 8a where the insertion hole 9 is formed, and has a substantially inverted L-shaped cross section so that a predetermined winding state can be easily formed and released. That is, a large number of locking pieces 11 are formed in order from the base end side of the inverted L-shaped release lever 10, while the free end side of the release lever 10 is extended along the instrument main body 2, and a grip for grip described later. 4. The inverted L-shaped release lever 10 is configured to release the above-mentioned locked state by being pressed and inclined toward the instrument main body 2. Note that the locking piece 11 of the release lever 10 and the locking portion 12 of the pressurizing / depressurizing member 3 can be locked by a well-known cloth fastener.

Further, along the lower surface of the fixed portion 8 on the arc,
The pressurizing / depressurizing member 3 is provided. This pressurizing member 3
Is formed by winding a rectangular arm band containing an air bag. That is, the end portion 3a of the pressurizing member 3
Is wound around the tip of one side 8a of the fixed part 8 on the arc, and the other end 3b is inserted through the insertion hole 9 of the fixed part 8. A large number of locking portions 12 corresponding to the locking pieces 11 of the release lever 10 are formed on the surface of the inserted pressure increasing / decreasing member 3.

Therefore, the pressurizing / depressurizing member 3 is set in advance in a state where a wound cylindrical space 7 is formed, and the length of the pressurizing / depressurizing member 3 is adjusted in accordance with the upper arm of the subject. Is adjusted (Y direction in FIG. 1), and the locking piece 11 of the release lever 10 and the locking portion 12 of the pressurizing / depressurizing member 3 are fitted to obtain a desired length. The upper arm of the subject is pressed by the application of pressure by the pressurizing pump in the meter body 1, and the pressure sensor detects this pressure.

Further, one side portion 2 of the instrument main body 2
A grip 4 for gripping is connected and formed on the upper side of each of the c and the surface 2d facing the side surface 2c.
The direction of disposition of the grip 4 is the same as that of the pressure
Are provided in the same direction (X direction in FIG. 1) as the cylindrical space 7 formed by winding. Therefore, it is easy for the measurement person such as a nurse to easily insert the cylindrical space 7 of the pressurizing / depressurizing member 3 into the arm of the person to be measured while holding the grip 4 by hand.

In the above embodiment, the grip 4
Is arranged at the center of the upper part of the instrument main body 2, but as shown in FIG. It is possible to In this case, since the grip 4 for gripping comes closer to the release lever 10, the release operation of the release lever 10 is more easily performed by the finger (thumb) P of the hand to be operated. In the embodiment shown in FIG. 4, an insertion hole is also provided on the other side 8 a of the fixing portion 8, and the pressurizing / depressurizing member 3 is inserted.

In this embodiment, it is general to provide a group of various operation buttons 5 and a display section 6 for the measurement results on the upper surface 2a of the instrument main body 2. In addition, a printer or the like for printing the measurement results is provided. Arrangement is also optional. It is also possible to dispose the operation button group 6 and the like on the grip 4 for gripping.

(Second Embodiment) In the second embodiment as well, as shown in FIG. 5, the meter main body 2, the pressure increasing / decreasing member 3, and the grip 4 are integrally formed. It is the same as the first case that the various operation buttons and the display unit 6 for displaying the measurement result of the blood pressure are provided on the upper surface of the main body 2.

However, the pressurizing / depressurizing member 3 of this embodiment is configured such that pressurizing and depressurizing are performed in a fixed part 8 on an arc which is partially disposed on the lower surface of the instrument body 2. The pressure is controlled by the pressure sensor described in the first embodiment. Therefore, unlike the above-described embodiment, the fixing portion 8 on the circular arc is not provided with an insertion hole or the like.

The first embodiment is different from the first embodiment in that the grip body 4 is connected to the instrument main body 2 in the same direction as the cylindrical space formed by winding the arm band (pressurizing / depressurizing member 3). This is the same as in the example. Therefore, only by inserting the cylindrical space 7 of the compression / decompression member 3 into the arm of the person to be measured in a state where the measurer such as a nurse grasps the grasping grip 4 with his / her hand, the measurement of the first embodiment is performed. As always,
The blood pressure measurement start state is obtained.

On the other hand, when the measurement of the blood pressure is completed, the pressure state of the compression / decompression member 3 can be released by reducing the pressure in the compression / decompression member 3.

Next, a use state in which the blood pressure is actually measured using the first embodiment will be described. First, FIG.
As shown in (1), the arm band (pressurizing / depressurizing member 3) is wound to form a tubular pressurizing / depressurizing member 3. Then, the locking piece 11 of the release lever 10 and the locking portion 1 of the pressurizing member 3
2 are superposed to form a cylindrical pressure increasing / decreasing member 3 having a predetermined size.

In this state, as shown in FIG.
All that is required is to hold the grip 4 of the apparatus body 1 by hand and pass it to the upper arm of the subject through the cylindrical space 7 of the pressurizing / depressurizing member 3 formed in the direction in which the grip 4 is disposed. . In this case, even if the subject is lying down, it can be passed through by simply raising his hand, and there is no need to get up for the measurement.

Then, the operation button 6 disposed on the upper surface side of the instrument main body 2 is operated to pressurize the pressurizing / depressurizing member 3 via a pressure pump or the like based on a command of the CPU in the instrument main body 2.

When the pressurizing / depressurizing member 3 is pressurized, the pressurizing is stopped when the tightening force reaches a predetermined value, and the upper arm is tightened by the pressurizing / depressurizing member 3 and then slowly loosened to remove the stopped artery. The moment when blood flow resumes and the beating sound starts to be heard is measured as systolic blood pressure. The moment when the artery is completely widened and the beating sound disappears is measured as the diastolic blood pressure. This measurement result is displayed on the display unit 5 of the instrument main body 2. The pulsating sound may be measured by applying a stethoscope to the back of the elbow while listening to the pulse sound.

On the other hand, when the measurement of the blood pressure is completed, the compression state of the compression / decompression member 3 can be released by opening the exhaust valve and lowering the pressure in the compression / decompression member 3. As shown in FIG. 3, when the release lever 10 provided in the vicinity of the grip 4 is pressed by a finger (thumb) P of one hand at the same time as this operation, the locking piece 11 of the release lever 10 is pressed.
And the locking portion 12 of the pressurizing / depressurizing member 3 is released.
Can be immediately loosened. Therefore, the device 1 can be easily removed from the upper arm of the subject.

In the method of measuring blood pressure, as described above, when the upper arm is pressed with the arm band and the pressure is reduced, blood flows into the artery. The maximum and minimum blood pressures are determined based on the arterial sound (Korotkoff sound) generated at this time. In addition to the Korotov method, blood pressure flows out of the artery when the upper arm is compressed with a cuff, and blood flows out into the artery. Although there is a law, the present invention can be used with any device that satisfies the requirements of the claims.

[0028]

As described above, the portable blood pressure measurement device according to the present invention has the grip for gripping the pressure increasing / decreasing member positioned on the upper surface side of the main body of the instrument in parallel with the insertion direction of the pressurizing member into the upper arm of the cylindrical space. As it is provided, by inserting the upper arm in the extension direction of the grip while holding the grip,
Since the upper arm can be inserted into the cylindrical space of the compression / decompression member, the mounting operation on the upper arm of the subject becomes extremely easy.

Further, the blood pressure can be easily measured with one hand as well as being easily transported, so that heavy labor of nurses and the like can be reduced. In addition, there is an effect that measurement can be performed in a comfortable posture in a bedridden patient or the like.
