Description

{WRIST WEARABLE BLOOD PRESSURE MONITOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood pressure monitor for measuring blood pressure, and more particularly, to a portable wrist blood pressure monitor which is worn on a wrist like a wristwatch, easily measures blood pressure, and is structurally very simple.

Generally, the blood pressure is measured as the blood pressure on the wall of the blood vessel, and the heart repeats shrinkage and relaxation about 60 to 80 times per minute. When the heart contracts and pushes out the blood, the pressure on the blood vessel is called 'contracting blood pressure' and is called 'hypertension' because it is the highest. In addition, when the heart relaxes and receives blood, the pressure of the blood pressure is called 'relaxed blood pressure' and the lowest is called 'the lowest blood pressure'.

The normal blood pressure of a normal person is 120 mmHg in shrinking blood pressure and 80 mmHg in relaxed blood pressure. More than 1 out of 4 adults in Korea are hypertensive, and this ratio is increasing rapidly after age 40, and some patients are classified as hypotension.

The problem of hypertension is that it may cause other complications that may pose a life threatening condition such as eye disease, kidney disease, arterial disease, brain disease, heart disease if left without proper management of hypertension. Therefore, in the case of the above-mentioned complication or the complication, continuous measurement and management of the blood pressure should be performed.

BACKGROUND ART [0002] Various kinds of blood pressure measuring devices have been developed as interest in health related diseases and geriatric diseases such as hypertension has increased.

The blood pressure measurement method includes a Korotkoff sounds method, an oscillometric method, and a tonometric method.

The stethoscope method is a typical pressure measurement method. In the process of decompressing the blood flow by applying sufficient pressure to the body part passing through the arterial blood, the pressure at the moment when the pulse sound is heard for the first time is measured by systolic pressure And the pressure at the moment when the pulsation disappears is measured by diastolic pressure.

The oscillometric method and the tonometric method are applied to a digitized blood pressure measuring device.

The oscillometric method is a method in which the body part through which the arterial blood passes is decompressed at a constant speed so as to block the arterial blood flow as in the stethoscopic method or a pulse wave generated during the pressure step- And measures systolic blood pressure and diastolic blood pressure.

Here, the pressure at the time when the amplitude of the pulse wave is maximum can be measured by the systolic blood pressure or the diastolic blood pressure, and the pressure when the rate of change of the pulse wave amplitude is rapidly changed is measured by the systolic blood pressure or the diastolic blood pressure You may.

In the process of reducing pressure at a constant rate after pressurization, the systolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum, and the diastolic blood pressure is measured later than the moment when the amplitude of the pulse wave is maximum. On the contrary, in the process of increasing the blood pressure at a constant speed, the systolic blood pressure is measured later than the moment when the amplitude of the pulse wave is the maximum, and the diastolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum.

Next, in the tonometric method, a constant pressure of a magnitude not blocking the blood flow of the artery is applied to the body part, and the blood pressure can be continuously measured using the size and shape of the pulse wave generated at this time.

As described above, the blood pressure monitor for measuring the blood pressure is the most basic medical equipment for measuring the blood pressure which is the basis of the health index. It is almost indispensable not only in general medical clinics but also for home blood pressure measurement It is in use.

However, in the case of a conventional blood pressure monitor, when the blood pressure is mostly measured, the blood pressure is measured by winding the blood pressure meter on the upper arm (upper arm or upper arm, part from the shoulder to the elbow) It is not easy to easily measure the blood pressure when desired.

For example, in the conventional oscillometric blood pressure monitor, a blood pressure monitor body and a pressure cuff, a tube plug, an air hose, and the like are required for wrapping around the forearm. It is bulky and has a disadvantage in that it is cumbersome to use because there is a lot of preparations in the preparation of the measurement, for example, the air hose must be fitted downward for proper measurement at the time of use or the cuff should be worn 1 to 2 cm above the elbow.

Particularly, since blood pressure varies depending on the body characteristics of the subject, patients having complications in the body need to immediately measure the blood pressure every time the subject feels abnormality in the body and / or the body. The mercury sphygmomanometer and the electronic blood pressure monitor Thereby providing inconvenience to the patients due to the following problems.

First, the mercury sphygmomanometer and the electronic sphygmomanometer use a cuff requiring air injection. However, the cuff has a bulky size, so that it is troublesome for a user to wear it in real time.

In addition, since the mercury sphygmomanometer using the pneumatic cuff is often excessively bulky and heavy for a patient whose blood pressure is frequently measured, it is inconvenient and inconvenient for the subject (patient) to carry around, and each time the blood pressure is measured, It is troublesome to detach and attach the blood pressure monitor.

Although there is a pneumatic electronic blood pressure monitor having the same accuracy as the conventional blood pressure monitor described above, when the blood pressure is measured periodically while the patient continues to carry it, since the electric pump and the infusion cuff are used, There is a problem that the behavior of the patient becomes uncomfortable.

In addition, there are non-pressure type electronic blood pressure monitors that measure blood pressure based on the pulse of the wrist or the fingertip and various parameters. However, since it is difficult to accurately specify the parameters and provide general purpose, the blood pressure is measured periodically It is difficult to apply to patients with

Meanwhile, in recent years, a blood pressure monitor capable of measuring blood pressure while being worn on a wrist, such as a wristwatch, has been developed in the name of a wrist blood pressure monitor, a wrist blood pressure monitor or a wristwatch blood pressure monitor.

However, the conventional wrist blood pressure monitor simply measures the blood pressure by wearing it on the wrist, so it is called a wristwatch type, but it is practically not so small as to be worn on a wrist. In other words, a conventional wrist blood pressure monitor can be said to be only slightly reduced in size so that it can be applied to the wrist instead of the upper wrist, and other wrist blood pressure monitors are structurally complicated, equipped with a mechanical / electronic pumping device for wrist pressurization, There is a problem such that the failure occurs easily and the manufacturing cost increases.

First, an embodiment of a wrist blood pressure monitor according to the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a side view showing an embodiment of a wrist blood pressure monitor according to the present invention, and Fig. 2 is a view showing a state where the wrist blood pressure monitor shown in Fig. 1 is worn on the left wrist of a user Fig. 3 is a perspective view showing the main body module of the wrist blood pressure monitor shown in Fig. 1, and Fig. 4 is a sectional view taken along the line II in Fig.

1 and 4, the wrist blood pressure monitor 100 according to the present embodiment is a portable blood pressure monitor that can be always worn on the wrist of a subject (user), that is, a blood pressure monitor on the wrist. The blood pressure monitor 100 includes a blood pressure sensing unit 110, (Wrist Strap) 110, and a display unit 130 for displaying the blood pressure of the user (i.e., the subject), i.e., the wearer.

In the present embodiment, the blood pressure sensing unit 110 is worn on the wrist by a wrist strap and contacts the wrist surface to measure the blood pressure of the subject. The wrist strap 120 binds the blood pressure sensing unit 110 to the wrist That is, the blood pressure sensing unit 110 is coupled to the wrist strap 120 in the form of a strap for wrist wrapping. The display unit 130 outputs the blood pressure value of the subject measured by the blood pressure sensing unit 110 to the outside.

The display unit 130 may be directly mounted on the wrist strap 120 so as to be disposed at a position spaced apart from or adjacent to the blood pressure sensing unit 110. In this embodiment, 110 and is fixed on the upper side of the blood pressure sensing unit 110. [

Therefore, in the present embodiment, the blood pressure sensing unit 110 and the display unit 120 are combined with each other to constitute a blood pressure monitor body (see FIG. 3), and the blood pressure sensing unit and the display unit are coupled to each other, The wrist strap 120 may be connected to the display unit 130. [0034]

More specifically, the blood pressure sensing unit 110 includes a case 111, an air bag 112, and a pumping chamber 113. In this embodiment, the case 111 is configured as a skeleton of the blood pressure sensing unit 110, the wrist strap 120 is connected to the case 111, A strap mounting groove 111c for connecting the wrist strap 120 is formed on one side and the other side of the case 111. The wrist strap 120 is connected to the pumping chamber 113, Lt; / RTI >

The airbag 112 is inflatably provided in the bottom groove 112a to press the wrist surface and is covered by the case 111. [ In the present embodiment, the bottom of the case 112a is sealed by the airbag 112. Accordingly, when the air bag 112 is filled with air, the air bag 112 is inflated downwardly of the case 111 to press the wrist surface.

The pumping chamber 113 is provided on the upper side of the case 111 and communicates with the airbag 112 and is contracted by an external pressure to supply air to the airbag 112. That is, the pumping chamber 113 expands the airbag 112 to allow the airbag 112 to press the wrist surface.

The pumping chamber 113 is contracted by an external pressure applied from the upper side to the lower side of the case 111 and air in the pumping chamber 113 is pushed toward the airbag 112 by the contraction of the pumping chamber 113 So that the airbag 112 is inflated downward.

In addition, when the force pressing the pumping chamber 113, that is, the external pressure, is removed, the pumping chamber expands and sucks the outside air. For example, the pumping chamber 113 is restored to its original shape by the self- do. For this purpose, the pumping chamber 113 may be provided with an elastic structure capable of restoring its shape.

The pumping chamber 113 is configured to fill the air bag 112 with air and is connected to the air bag 112 at an upper portion of the case 111 as described above.

When the user wears the blood pressure monitor 100 on the wrist of one hand and presses the upper part of the pumping chamber 113 downward with the other hand, specifically the palm or fingers, the inside of the pumping chamber 113 Air is supplied to the airbag 112 and when the force pressing the pumping chamber 113 is removed, the pumping chamber 113 swells to its original shape due to its own elasticity, and sucks the outside air.

Therefore, the pumping chamber 113 can be structured such that the outside air is naturally introduced into the pumping chamber 113 as the pumping chamber 113 is restored to its original shape. For example, the pumping chamber 113 has a resilient material such as a rubber material and has a structure that is restored to its original shape by elasticity when an external pressure, that is, a force pressing the pumping chamber 113 from the outside is removed, A structure in which a spring is applied inside) or a material is sufficient.

A check valve 115 is connected to one side of the pumping chamber 113 to supply external air to the pumping chamber 113. The check valve is a valve that implements unidirectional air flow as is well known, and the first check valve 115 allows only the inflow of air from the outside of the blood pressure sensing unit 110 into the pumping chamber 113 And does not allow emissions.

The first check valve 115 is provided in a path for guiding the inflow of air into the pumping chamber 113 from the outside of the air intake port 111a of the pumping chamber 113 or the blood pressure sensing unit 110 And blocks the flow of air from the inside of the pumping chamber 113 to the outside.

The air flow between the airbag 112 and the pumping chamber 113 is made only in one direction, i.e., from the pumping chamber 113 to the airbag 112 direction. That is, a separate check valve 116 (hereinafter referred to as a "second check valve") is provided to pass the fluid (air) flowing from the pumping chamber 113 only to the air bag 112 and shut off the flow in the opposite direction Is provided in a communication hole 111d connecting the airbag 112 and the pumping chamber 113 so that the airbag 112 and the pumping chamber 113 communicate with the second check valve 116, Lt; / RTI >

The second check valve 116 is provided in the communication hole 111d for communicating the airbag 112 and the pumping chamber 113 so that the airbag 112 is pumped from the pumping chamber 113. [ Thereby preventing the air introduced into the pumping chamber 113 from flowing back to the pumping chamber 113 again.

An exhaust valve 117 for reducing the pressure of the airbag 112 is connected to one side of the airbag 112. The exhaust valve 117 gradually discharges air when the airbag 112 is pressed by the user to realize the gradual depressurization of the airbag 112.

The exhaust valve 117 is provided in the exhaust port 111b of the airbag 112. An example of the exhaust valve 117 may be a linear valve having a constant air discharge over time .

In the present embodiment, the exhaust port 111a and the communication hole 111d are formed in the case 111. [ The intake port 111b is also formed in the case 111 but the position of the intake port 111a is not limited thereto and may be formed directly at another position such as a side wall of the pumping chamber 113 .

The case 111 maintains the shape of the bottom groove 112a constant when the pumping chamber 113 receives an external pressure. For example, the case 111 has a hard material, that is, a hard material, Thereby preventing shrinkage of the airbag 112 when the pumping chamber 113 is pushed. More specifically, the case 111 has a hard plastic, a hard rubber, or a metal material, and functions as a hard shell for protecting the airbag 112.

In this embodiment, the case 111 is provided with a pressure sensor 114 for sensing the internal pressure of the airbag 112, and the pressure signal is transmitted to a circuit board of a display unit described later. As the pressure sensor 114, various sensors capable of measuring air pressure can be applied.

The case 111 and the pressure sensor 114 to which the airbag 112 is applied may be modularized into a pressure measurement module for blood pressure measurement. A pressure measurement module that is attached to the user's wrist by the wrist strap 120 and presses the wrist surface and measures the pressure for blood pressure calculation includes a case 111 having the air bag 112 and the air bag 112, And a pressure sensor 114 for sensing the pressure of the fluid.

In this embodiment, the wrist strap 120 has a structure in which the right and left straps are connected by a fastening device such as a buckle or a Velcro, or a structure in which a separate fastening device is used But may be a continuous closed loop structure. For example, the wrist strap 120 may be constructed as an integral band structure that can be resiliently widened, that is, an elastic wristband that can be extended widely by an external force.

The display unit 130 includes a blood pressure display window 131 and a circuit board 132. The pressure sensor 114 is electrically connected to the circuit board 132. [ The pressure sensor 114 senses the pressure of the airbag 112 and transmits a pressure signal to the circuit board 132.

In the present embodiment, the pressure sensor 114 is provided on one side wall of the airbag 112 and is connected to the circuit board by a signal line (not shown), and the circuit board 132 is connected to the blood pressure display window 131 And the display unit 130 is disposed under the display unit 130. Of course, the pressure sensor 114 may be provided on the outside of the case 111, for example, on the display unit 130. More specifically, the pressure sensor 114 may be connected to the airbag 112 through an air hose Thereby sensing the pressure of the airbag 112.

The display unit 130 has a blood pressure display function and may further have a clock function. For example, the blood pressure display window 112 may be switched to a clock mode and a blood pressure output mode, or a clock, for example, an electronic clock may be separately applied to the display unit 130. In addition, the display unit 130 may be provided with an alarm function, for example, an alarm function for notifying the blood pressure check time and / or an alarm function for notifying that the blood pressure check is normally completed. Accordingly, the user can accurately measure / record the blood pressure at a time when the blood pressure check is required.

The display unit 130 may be provided on the upper side of the blood pressure sensing unit 110, more specifically on the upper side of the pumping chamber 113, The display unit 130 pressurizes the pumping chamber 113 to supply the air to the airbag 112. [

More specifically, when the user wears / carries the wrist blood pressure monitor 100 on the wrist (for example, left wrist) of one arm and checks the blood pressure, it is necessary to use the palm or fingers of the other hand When the upper side of the pumping chamber 113, that is, the upper side of the display unit 130 is pushed downward, the filling of the airbag 112 and the pressing of the wrist surface can be simultaneously performed.

5 to 7, in a state in which the blood pressure monitor unit 110 is positioned on either of the wrists, for example, on the radial artery of the left wrist (see FIG. 5) 6, air is supplied to the airbag 112 from the pumping chamber 113 by pushing the upper side of the blood pressure monitor main body (the upper side of the display unit) downward by using the palm or fingers of the hand (right hand) The airbag 112 is inflated and at the same time the wrist surface of the region where the radial artery passes by the airbag 112 is pressed.

7) of the airbag 112 is advanced by the exhaust valve 117 while the pressurization of the blood pressure monitor main body is maintained for a predetermined time, and the blood pressure is measured through this process.
