Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic wrist blood pressure monitor that measures blood pressure by isolating arteries in the wrist. To provide a small and simple wrist blood pressure monitor in which a cuff case for storing and a grip housing a meter body are connected and integrated into one body, and the grip can be housed lying down inside the cuff case.

[Conventional technology]

The conventional wrist blood pressure monitor, like the upper arm blood pressure monitor, has a cuff (empty rubber bag) formed in a substantially cylindrical shape, and includes an air pressure supply device such as an air pressure pump that supplies compressed air to the cuff, and an air pressure supply device such as an air pressure pump that supplies compressed air to the cuff. A blood pressure measuring device that measures blood pressure by analyzing pulse wave information sent from the cuff and an instrument body that includes a display device that displays the measured blood pressure are provided separately, and each is connected to a rubber tube and a lead. They are connected by wires, etc.

[Problem that the invention seeks to solve]

The above-mentioned conventional wrist blood pressure monitor is a separate type even if it is for home use or portable use, and has the disadvantage that the rubber tube, lead wire, etc. exposed between the cuff case and the meter body may come off during use or cause poor connection. Ta.

Furthermore, since it was a separate type, the device was not only large, but also complicated to operate, making it almost the same as a blood pressure monitor for the upper chamber.

In other words, if it is the same as a blood pressure monitor for the upper arm, it is sufficient to measure blood pressure at the upper arm, which has a proven track record and has good accuracy, and there is no need to measure it at the wrist.

This invention solves the above-mentioned conventional drawbacks by integrating the instrument body and the cuff case.When not in use, the instrument body can be stored in the cuff case, and when measuring blood pressure, the instrument body, that is, the grip that houses the instrument body, can be removed from the cuff case. The purpose of the present invention is to provide a unique automatic electronic blood pressure monitor for the wrist that has excellent operability and allows the cuff to be attached to the wrist by pulling it up.

[Means for solving the problem] This problem is solved by installing a grip in a predetermined position in front of the wrist cuff so that it can be easily grasped with the hand, for example, like shaking hands, and installing a blood pressure measurement device in the grip. This is achieved by incorporating part or all of the measuring device main body.

In other words, when you attach your wrist to the cuff case and lightly squeeze the grip in front of the cuff case, as if shaking hands, the position of the radial artery in your wrist is automatically determined, and the blood pressure measurement sensor installed in the cuff is placed on your wrist. Next, after making the cuff case into a cylindrical shape, press the start switch provided on the grip, and the air pressurization pump built into the grip will operate, sending air to the cuff and starting blood pressure measurement. be done.

The invention will be described in detail below based on the drawings.

FIG. 1 is a perspective view showing a first embodiment.

This automatic wrist blood pressure monitor 1 includes a cuff case 3 that houses a cuff 2 for compressing the wrist, an air pressurizing pump that pressurizes the cuff 2, and an instrument body (not shown) that contains an electronic circuit that measures blood pressure. It consists of a grip 4 that stores the.

The cuff case 3 basically opens upward, and a grip 4 is attached to its front extension.

A cuff 2 made of a rubber bag is placed on a cuff case 3 made of band cloth, and the cuff 2 is connected to a rubber tube 5, an air pressure pump of a grip 4, and a pressure sensor.

Place your hand on the cuff 2, grip the grip 4, wrap the band of the cuff case 3 around the wrist 8 as shown in Figure 2, and then press the start switch 6 of the grip 4. Air is sent to the cuff 2 through the rubber tube 5 from the air pressure pump built into the cuff 2, and the cuff 2 is rapidly closed in 2 to 3 seconds.
Pressurize the wrist to prevent blood flow.

It is desirable to set the upper limit of the pressurization to about 40 aHg higher than the patient's expected blood pressure.

When the predetermined pressure is reached, the cuff 2 is slowly depressurized by the slow exhaust valve. Pulse wave information obtained from the cuff internal pressure along the way is sent to the instrument body through the cuff 2 rubber tube 5 and analyzed, and the measured value is displayed on the display device 7 provided at the top of the grip 4.

The main body of the instrument may be equipped with any known devices necessary to measure the blood pressure, such as a power source, battery, control device, pressure sensor, rapid exhaust valve, slow exhaust valve, memory device, buzzer, sound, and others. Needless to say.

In the second embodiment, as shown in FIG. 3, part of the cuff case 3 is a base 10 made of hard synthetic resin or metal, and a grip 4 is provided on an extension of the base 10. The base 10 and the grip 4 are connected by a hinge, a soft material, or a spring material 11, so that the grip 4 is folded toward the cuff case 3 side. base l
O is preferably provided with a ring 13 in which the band 12 is looped and folded back, and the band 12 of the cuff case 3 is passed through the ring 13 to form a folded cylindrical body. Also, use Velcro to fix it. You may do so.

In the third embodiment, as shown in Fig. 4, the wrist is passed through a hard cuff case 14 that is open at the top in a U shape, the grip is grasped, and the latch 15 is hung, or the cuff case is The opening of the letter-shaped cuff case 14 is made into a cylindrical shape. At this time, it is preferable to use a hinge 16 or a flexible material or a spring material for the lower part of the cuff case 14.

In the fourth embodiment, a shape memory alloy or resin is used for part or all of the hard cuff case, and the memory is restored by heating or cooling, thereby deforming the U-shaped opening into a cylindrical shape. .

The shape memory material used at this time may be nickel, titanium, copper, or any other material suitable for this purpose, but materials that can be heated with electricity are preferred.

〔effect〕

As explained above, in this invention, a grip is provided at a predetermined position in front of the wrist cuff, and the start button is operated after grasping the grip with the hand wearing the cuff, so there is no possibility of malfunction. In addition, the positioning of the wrist, that is, the position of the radial artery in the wrist, is suppressed, making it easier to set up the measurement sensor. Not only can a more accurate measurement method such as the method be freely used alone or in combination, but also psychological stability can be obtained by gripping the grip, which has the effect of enabling more accurate blood pressure measurement.

Furthermore, since the upper part of the cuff case is open, it is extremely easy to attach the wrist to the cuff.

Furthermore, since the grip can be housed in the opening of the cuff case, it is possible to reduce the size of the grip.
