A pulse measuring apparatus of a human-body touch strength sensing type

The present invention relates to a pulse measuring apparatus, and more particularly, to build a small-scale module environment that can accurately measure the contact strength of the human body in contact with a series of detection points according to the change in blood pressure flowing through the human body, Based on this, you can use a complex device, such as a conventional heart rate monitor, or a simple process of contacting a part of your body with a series of sensing points without the complicated procedure of visiting a doctor / nurse individually. It relates to a human body contact intensity sensing pulse measuring device that can be induced to easily obtain the measurement results.

Traditionally, the pulse measurement of the human body is performed by a direct touch diagnosis process such as a doctor / nurse or the like, for example, Korean Patent Publication No. 1987-9226 "Heart ejection catheter and blood flow catheter ", Korean Patent Publication No. 1990-59," Anti-arrhythmic assisted regulator using a pre-release period to distinguish between physiological and pathological deficits ", Korean Patent Publication No. 1999-66566" For the elderly or rehabilitation trainers It is generally made by a precision heart rate measuring apparatus as disclosed in "a treadmill system and its traveling speed control method."

However, since these conventional pulse measuring methods have various disadvantages described below, under the conventional system, a user who wants a pulse measuring device is more convenient and accurate at the right time when he or she needs it, unless special measures are taken. I can't measure my pulse.

Here, the pulse measuring method of the human body by the precision heart rate measuring device can exhibit a high reliability since human intervention is minimized, compared to the pulse measuring method by the doctor / nurse mentioned above, but such a precision heart rate measuring device Is itself very expensive, the user using it has no choice but to pay more than necessary for the purchase of the device, and since the precision heart rate measuring device is very difficult to operate, the user who uses it has to The inconvenience of having to be familiar with one by one is inevitable.

Moreover, since the conventional precision heart rate measuring device is very large and inconvenient to carry, the user who uses it has no choice but to suffer the inconvenience of not being able to smoothly perform the desired pulse measuring process outdoors.

Accordingly, an object of the present invention is to build a small-scale module environment that can accurately measure the contact strength of the human body in contact with a series of sensing points according to the change in blood pressure flowing through the human body, and based on this, the user has a conventional heart rate You can easily obtain the pulse rate you want by using a simple device, such as a measuring device, or a simple procedure of contacting a part of your body with a series of detection points without the complicated procedure of visiting a doctor / nurse. To induce.

Another object of the present invention is to simplify the series of pulse measuring mechanisms to detect the human body contact strength by the detection point, thereby maximizing the portability of the device and minimizing the waste of unnecessary time and cost required for pulse measurement. have.

In order to achieve the above object, in the present invention, the contact strength detection point for providing a contact portion of the human body to be measured pulse rate, and the electrical contact of the front contact intensity detection point one-to-one, the blood of the human body in contact with the contact sensitivity detection point According to the flow state, the circuit state is different, the sensing circuit unit for continuously outputting a series of human body contact intensity sensing signals, the power supply unit for selectively applying a series of necessary voltages for driving the sensing circuit unit, the sensing circuit unit and It is electrically connected to the power supply, and at the start of any pulse measurement requested by the user, the power supply is controlled to drive the sensing circuit, and when the human body contact intensity detection signal is continuously output from the sensing circuit, Analyze the number of changes per hour of the intensity detection signal and open the pulse measurement results of the human body in contact with the contact intensity detection point. , Composed of a combination of pulse output measurement unit, which discloses a human body contact sensing pulse intensity measuring device.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail the human body contact strength sensing pulse measuring apparatus according to the present invention.

As shown in FIG. 1, the human body contact intensity sensing pulse measuring apparatus 100 according to the present invention is largely a human body contacting unit 30, a sensing circuit unit 20, a power applying unit 50, and a pulse measuring unit 10. ) And the like. In this case, a touch strength sensing point (SP) is provided on the human body contact portion 30 to provide a contact portion of the human body B to be measured pulse rate.

In this case, when the body B is in contact with the contact sensitivity detection point 40 in a state in which the previous sensing circuit 20 is electrically connected to the contact strength detection point 40 one-to-one, the blood of the body B is affected. According to the flow state, by varying the circuit state, serves to continuously output a series of human body contact intensity detection signal to the pulse measuring unit 10, the power supply unit 50 is controlled by the pulse measuring unit 10 Accordingly, it performs a role of selectively applying a series of necessary voltages required for driving the sensing circuit unit 20.

In addition, when the user requests an arbitrary pulse measurement start while the pulse measuring unit 10 is electrically connected to the sensing circuit unit 20 and the power applying unit 50, the power applying unit 50 may be turned on. By controlling and driving the sensing circuit unit 20, and when a series of human body contact intensity sensing signals are continuously output from the sensing circuit unit 20, the number of changes per hour of the human body body contact intensity sensing signal is analyzed to determine the contact strength. It calculates and outputs the pulse measurement result of the human body B in contact with the sensing point 40.

In this case, as shown in FIG. 2, the above-described sensing circuit unit 20 outputs a signal in which the static and dynamic states are different according to the blood pressure flow state of the human body B being in contact with the contact strength detecting point 40. The output element 21, for example, the inverter, and electrically connected to the output element 21, while charging the voltage supplied from the above-described power supply unit 50 for a predetermined time, the previous contact strength detection point ( When the human body B contacts 40, the first capacitor C1 for discharging part of the charged charge toward the human body B to change the output signal state of the output element 21, and the first capacitor C1. Electrically connected to the capacitor (C1), forms a series of RC circuit by the linkage with the human body (B), and when the charge stored in the first capacitor (C1) is discharged, so that the redistribution of the charge is possible While accepting electric charges, the first capacitor 1 is adapted to the RC time constant. Tana is made of a combination of a second capacitor (C2) to vary the magnitude of the voltage.

Under the human body contact intensity sensing pulse measuring apparatus 100 of the present invention having such a configuration, any user who wants to measure the pulse contacts a part of his / her body B, for example, a finger, with the contact strength detecting point 40. In this state, when the pulse measuring unit 10 is driven through a series of computational operations, the pulse measuring unit 10 first discharges the first capacitor C1 and the second capacitor C2 and initializes them. Thereafter, the voltage Va is supplied to the node P using the power supply unit 50 and the buffer 23, and as a result, as shown in FIG. 3, the voltage Va is instantaneously supplied to the first capacitor C1. Charge for a specific time t1, t2. Here, the human body B of the user who may be in contact with the contact strength detecting point 40 may be variously selected according to the user's intention, in addition to the front finger, the ear, the wrist, the neck, and the like.

At this time, the second capacitor C2 forms an RC circuit by linking with the human body resistor Rb whose value is determined according to the contact strength of the human body B, for example, the finger, and the voltage Va is the human body resistor. Since the first capacitor C1 is charged in a much shorter time than the time constant RbC2 composed of the Rb and the second capacitor C2, the second capacitor while the voltage Va is instantaneously charged to the first capacitor C1. The capacitor C2 is hardly charged with a voltage, and as a result, the voltage of the contact strength detecting point 40 rises to Va in the same manner as the first capacitor.

In this state, when the voltage applied to the contact strength detecting point 40 is discharged by the discharge current of the human body resistance Rb whose value is determined by the pressure of blood flowing along the human body, the first capacitor C1 is discharged. ), The voltage Va charged in the discharge is discharged to the second capacitor C2.

At this time, as mentioned above, since the second capacitor C2 forms the RC circuit by linking with the human body resistor Rb, the second capacitor C2 uses the RC time constant as the charge discharged from the first capacitor. According to FIG. 3, the voltage Va charged in the first capacitor C1 forms an RC redistribution curve, and the final voltage (that is, Va is the first capacitor). The voltage is divided into C1) and the second capacitor C2 and is balanced toward Vf. In this case, the final voltage Vf has a value as shown in Equation 1 below, for example.

As such, when the voltage Va filled in the first capacitor C1 falls in a RC curve and falls below a threshold voltage Vm set in the previous output element 21, the input terminal voltage of the output element 21 is decreased. For example, it is changed to Low, and accordingly, the output element 21 is a series of human bodies reflecting, for example, "falling time DELTA T1 until the voltage Va filled in the first capacitor C1 falls to Vm". The contact strength detection signal can be output to the pulse measuring unit 10 electrically connected to the self.

At this time, the "falling time until the voltage Va filled in the first capacitor C1 falls to Vm" is determined by the RC time constant, and the RC time constant has the same value as in Equation 2 below. Here, the coefficient Rb for determining the RC time constant is determined by the pressure of blood flowing through the human body B. Consequently, when the pulse of the human body B is obsessive, the RC time constant becomes relatively small. "Falling time until the voltage Va charged in the first capacitor C1 falls to Vm" is relatively shorter than when the pulse of the human body B is weak, and the pulse of the human body B is weak , RC time constant value is relatively large, the "fall time until the voltage Va charged in the first capacitor (C1) falls to Vm" is relatively longer than when the pulse of the human body (B) is obsessive.

In other words, when a series of human body contact intensity sensing signals reflecting the "fall time until the voltage Va filled in the first capacitor C1 falls to Vm" from the output element 21 is transmitted, the pulse measuring unit 10 transmits the pulse measuring unit 10. Immediately, the "pulse high and low change" of the human body B being in contact with the contact strength detecting point 40 can be easily grasped at each time point.

For example, at any point in time, the falling time DELTA T2 from the output element 21 to " the voltage Va filled in the first capacitor C1 as shown in FIG. 4 falls to Vm " When a series of human body contact intensity detection signals reflecting T1 < DELTA T2 are transmitted, the pulse measuring unit 10 indicates that the voltage Va at which the human body B pulse at this point is filled in the first capacitor C1 is Vm. It is easy to see that a series of human body contact intensity detection signals reflecting the fall time ΔT1 ”until falling down to the body is weaker than the human body (B) pulse at the time point.

Under such a base environment, the pulse measuring unit 10 receives the human body contact intensity detection signal continuously output from the output element 21 for a predetermined measurement time, and as shown in FIG. By real-time analysis of the reflected pulse intensity values M1, M2 .... in real time, it is possible to measure the "number of times these values change up / down the average line L1", thereby contacting the contact strength detecting point 40 It is possible to generate a pulse measurement result of the human body (B) in progress, and later, by outputting the pulse measurement result is completed through the display window (not shown), the user is in contact with the contact strength detection point 40 You'll be guided to know your pulse accurately.

As described above, the present invention builds a small module environment that can accurately measure the contact strength of the human body in contact with a series of detection points according to the change in blood pressure flowing through the human body, and based on this, the user can measure the conventional heart rate. Using a complex device such as a device, or without the complicated procedure of visiting a doctor / nurse, you can easily obtain the pulse rate you want by simply touching a part of your body to a set of detection points. It can be derived.

On the other hand, as shown in Figure 6, the human body contact intensity sensing pulse measuring apparatus 200 according to another embodiment of the present invention is arranged on the human body contact portion 230, the detailed contact of the pulse measurement target human body (B) A plurality of microscopic contact intensity detection points 240 that provide a portion, and the human body contact is electrically connected one-to-one with the microscopic contact intensity detection points 240, the microscopic contact sensitivity detection points 240 in detail According to the blood flow state of the circuit, by varying the circuit state, a plurality of sensing circuits 210 for continuously outputting a series of human body contact intensity sensing signals and a series of necessary voltages required for driving the sensing circuits 210 It is electrically connected to the power supply unit 250 for selectively applying, the sensing circuits 210 and the power supply unit 250, and at the start of any pulse measurement requested by the user, the power supply unit 250 is Control to drive the sensing circuitry 210 When the human body contact intensity detection signal is continuously output from the circuits 210, the human body B in contact with the microscopic contact intensity detection points 240 by analyzing the number of times of change of the human body contact intensity detection signal on an average. It consists of a combination of the pulse measuring unit 220 for calculating and outputting the pulse measuring result of the.

In the above-mentioned embodiment, since the contact strength detection point 40 constitutes a single unit of a big size corresponding to, for example, the contact area of the finger, the detection associated with the contact strength detection point 40 is sensed. The circuit unit 20 and the pulse measuring unit 10 may also include measurement values obtained in an area unnecessary for pulse measurement, for example, "an area left in contact with the human body during the measurement time." If no additional measures are taken, the pulse measuring unit 10 only needs to be configured with a circuit that ensures higher accuracy than necessary, which causes a problem that the accurate pulse measuring result can be calculated.

In another embodiment of the present invention, in view of the occurrence of such a problem, as shown in the drawing, the front contact intensity detection point 40 is the detail of the pulse measurement target human body B, for example, the skin line SL of the finger. ) And a plurality of micro contact strength detection points 240 in contact with each other, and thereby, sensing circuit units 210 and pulse measuring unit 220 associated with each micro contact strength detection points 240. It is possible to select only the values obtained in the contact region where the light is required for the pulse measurement, that is, the contact intensity is greatly changed, and the values obtained in the non-contact region can be excluded from the calculation process, thereby improving the reliability of the final pulse measurement result. It can be greatly improved.

Under the human body contact intensity sensing pulse measuring apparatus 200 according to another embodiment of the present invention having such a configuration, any user who wants to measure the pulse has his / her human body B on the microscopic contact intensity detecting points 240. When the pulse measuring unit 220 is driven through a series of computational operations in a state in which a finger is touched, for example, as illustrated in FIG. 7, the pulse measuring unit 220 firstly detects each of the sensing circuit units. After discharging the first capacitor C1 and the second capacitor C2 disposed at 210 and initializing them, the voltage is applied to each node P using the power supply unit 230 and the buffer 212. Va is supplied, and through this, voltage Va is instantaneously charged to each first capacitor C1.

At this time, each of the second capacitors C2 is connected to the human body resistances Rb1, Rb2, and Rb3 ... which are determined according to the contact strength of the human body B, for example, the finger skin line SL. RC circuits are formed, and the voltage Va is each first capacitor C1 in a much shorter time than the time constant RbC2 composed of each of the human body resistors Rb1, Rb2, Rb3 ... and the second capacitor C2. Since the second capacitor C2 is temporarily charged while the voltage Va is instantaneously charged to each of the first capacitors C1, the respective contact strength sensing points 241, 241, 243 The voltage of ... rises to Va similarly to each 1st capacitor C1.

In this state, the contact strength sensing points 241, 241, 243 ... are discharged by the discharge current of each of the human body resistances Rb1, Rb2, Rb3 ... which is determined by the pressure of blood flowing along the skin line SL. When the applied voltage is discharged, the voltage Va charged in each of the first capacitors C1 is discharged to each of the second capacitors C2.

At this time, as mentioned above, since each of the second capacitors C2 forms an RC circuit by linking with the human body resistors Rb1, Rb2, and Rb3 ...., each of the second capacitors C2 The electric charges discharged from each first capacitor C1 are accepted in accordance with the RC time constant, and as a result, the voltage Va charged in each first capacitor C1 draws an RC redistribution curve and decreases toward the final voltage Vf. do.

As such, when the voltage Va filled in each of the first capacitors C1 falls along the RC curve and falls below the threshold voltage Vm set in each output element 211, the input terminal voltage of each output element 211 is decreased. For example, it is changed to low, and thus, each output element 211 detects a plurality of human body contact strengths, for example, reflecting the "fall time until the voltage Va, which has been filled in each first capacitor C1, falls to Vm." The signal can be output to the pulse measuring unit 220 electrically connected to the self.

Under such a base environment, the pulse measuring unit 220 receives a human body contact intensity detection signal continuously output from each output element 211 for a predetermined measurement time, and as shown in FIG. Pulse intensity values for each time point reflecting the signal are analyzed in real time.

At this time, as mentioned above, in another embodiment of the present invention, each of the minute contact strength detection points 241, 242, 243 ... is in contact with the skin line SL of the finger, and the minute contact strength detection points ( Since 241,242,243 ... are connected one-to-one with the plurality of sensing circuits 210, the pulse measuring unit has a plurality of pulse intensity values at any time points t7, t8, etc. included within a predetermined measurement time, ..., m1, m2, m3. It is possible to acquire and analyze m4, m5, m6 ... at the same time in real time.

Here, since the fine contact strength detection points 241, 242, 243 ... are in contact with the skin line SL, the corresponding fine contact intensity detection points easily indicate a change in the human contact intensity according to the pulse, for example, Since the fine contact strength detecting point 244 is not in contact with the skin line SL, there is no change in the value.

At this time, in the present invention, as described above, by selectively extracting only the values represented by the fine contact strength detection points 241,242, 243 ... which can easily detect the change, and calculating only the values, the "pulse intensity value obtained at last" is obtained. To increase the analytical precision ".

Thereafter, the pulse measuring unit 220 averages the plurality of pulse intensity values described above, calculates a series of average pulse intensity values M1, M2 ..., and analyzes the average pulse values in real time, and the values are " average line. The number of times of change of L2 up / down "is measured, thereby making it possible to generate a precise pulse measurement result of the human body B in contact with the micro-contact strength detection point 240, and later, By outputting the completed pulse measurement results through the display window, it is possible to guide the user to accurately determine his or her pulse in contact with the fine contact strength detection points 240.

On the other hand, as shown in Figure 9 and 10, the human body contact strength sensing pulse measuring apparatus 300 according to another embodiment of the present invention is any information processing device such as laptop (1), mobile phone (2) In addition to the above-described pulse measuring role, it is also possible to perform a series of fingerprint sensor role, touch pad role, etc. to determine the presence or absence of contact of the human body.

In this case, the user can use the pulse measuring apparatus 300 of the present invention as a tool for easily measuring his / her pulse, and at the same time, can easily dually use a tool such as a fingerprint sensor or a touch pad.

However, when a user assumes that the pulse measuring apparatus 300 of the present invention is used not only as a series of pulse measuring tools, but also as a tool such as a fingerprint sensor and a touch pad, the user is on the human body 330. Since the human body, for example, the user has to move the finger frequently, such a situation may lead to the question whether the human body contact intensity sensing pulse measuring apparatus of the present invention can normally perform the role of the pulse measurement. However, from the point of view of the pulse measuring unit of the present invention, since the matter of interest is only "measuring the number of times the pulse intensity values change up / down the average line", even if the user On the fine contact strength detection point, even if you move your finger frequently, the pulse measuring apparatus of the present invention can easily obtain the human body contact strength detection signal required by any contact strength detection point irrespective of this, As a result, the user's pulse measurement process can be performed normally.

At this time, as shown in Figure 11, the pulse measuring apparatus 300 of the present invention in order to simultaneously perform not only the role of the pulse measurement, but also a series of fingerprint sensor role, touch pad role, etc. to determine the presence or absence of human body contact. Human body contact intensity sensing pulse rate measuring apparatus 300 of the present invention, as well as the above-described human body contacting unit 330, sensing circuit unit 310, power supply unit 350, pulse measuring unit 320, a series of human body contact detection The processor 360 should be further provided.

In this case, when the human body contact sensing processor 360 is continuously connected to the sensing circuit units 310 and the human body contact intensity sensing signal is continuously output from the sensing circuit units 310, the human body touch sensing processor 360 according to the human body touch intensity sensing signal In addition, it is determined whether the human body is in contact with the micro contact strength detection point 340, and selectively obtains values obtained from the micro contact strength detection point 340 whose contact intensity changes, and the operating system of the information processing apparatus (1, 2). (3) It performs the role of outputting.

Under the human body contact intensity sensing pulse rate measuring apparatus 300 according to another embodiment of the present invention having such a configuration, for example, any user who wants to simultaneously use the touch pad, pulse rate measurement, and the like may be configured as shown in FIG. 12. Similarly, in a state in which a part of the human body B, for example, a finger is contacted with a micro contact strength detection point (for convenience, in the following description, it is assumed that only one micro contact strength detection point 340 is disposed). When the pulse measuring unit 320 is driven through a series of computational operations, the pulse measuring unit 320 first discharges the first capacitor C1 and the second capacitor C2, and initializes them. The voltage Va is supplied to the node P using the applying unit 350 and the buffer 312, and thereby, the first capacitor C1 is charged with the voltage Va for an instant of time t9 and t10.

At this time, the second capacitor C2 forms an RC circuit by linking with the human body resistor Rb, and the voltage Va is much higher than the time constant RbC2 composed of the human body resistor Rb and the second capacitor C2. Since the first capacitor C1 is charged in a short time, the voltage is not charged to the second capacitor C2 while the voltage Va is instantaneously charged to the first capacitor C1. The voltage at the contact strength sensing point 340 rises to Va in the same manner as the first capacitor C1.

In this state, when the voltage applied to the fine contact strength detecting point 340 is discharged by the discharge current of the human body resistor Rb, the voltage Va charged in the first capacitor C1 is also changed to the second capacitor ( Discharged to C2).

At this time, as mentioned above, since the second capacitor C2 forms an RC circuit by linking with the human body resistor Rb, the second capacitor C2 is discharged from the first capacitor C1. , According to the RC time constant, and finally, as shown in FIG. 13, the voltage Va charged in the first capacitor C1 forms an RC redistribution curve, and the final voltage (that is, Va is the first capacitor ( The voltage is divided into C1) and the second capacitor C2 and is balanced toward Vf.

As such, when the voltage Va filled in the first capacitor C1 falls in a RC curve and falls below a threshold voltage Vm set in the previous output element 312, the input terminal voltage of the output element 312 is decreased. For example, it is changed to low, so that the output element 312 detects a series of human body contact strengths, for example, reflecting "falling time DELTA T3 until the voltage Va filled in the first capacitor C1 falls to Vm." A signal and a series of human body contact detection signals indicating that the human body has been contacted may be output to the pulse measuring unit 320, the human body contact detection processor 360, and the like electrically connected to the human body.

In this state, the pulse measuring unit 320 receives the human body contact intensity detection signal continuously output from the output element 312 for a predetermined measurement time, and then the pulse intensity values for each time point at which the human body contact intensity detection signal is reflected in real time. By analyzing, it is possible to measure the "number of times that these values change up / down the average line", thereby generating a pulse measurement result of the human body B in contact with the contact strength detection point 340. Afterwards, the generated pulse measurement result is output through the display window of the information processing device (1, 2), so that the user can accurately identify his / her pulse being in contact with the contact intensity detecting point (340). do.

At the same time, the human body touch detection processor 360 receives a human body touch detection signal continuously output from the output element 311, and then, in response to the human body touch detection signal, the human body contacts the fine contact strength detection point 340. After confirming that the result of the verification is output to the operating system 3 of the information processing apparatuses 1 and 2, the operating system 3 can be guided so as to promptly take appropriate measures suitable for human contact.

After all, the user through the role of the previous pulse measuring unit, the human body touch detection processing unit, the pulse measuring device 300 of the present invention as a tool that can easily measure their own pulse, as well as the usual fingerprint sensor, touch Tools such as pads can be used easily.

As described in detail above, the present invention builds a small module environment that can accurately measure the contact strength of the human body in contact with a series of detection points according to the change in blood pressure flowing through the human body, and based on this, Using complex devices like conventional heart rate monitors, or without the complicated procedure of visiting a doctor / nurse, you can easily get the pulse rate you want by simply touching a part of your body to a set of detection points. Induce it to be acquired.

By the implementation of the present invention, when a series of pulse measuring mechanisms are simplified to the human body contact intensity detection type by the detection point, the user can maximize the portability of the device, unnecessary time required for pulse measurement, cost, etc. The effect of minimizing waste can be easily obtained.

The present invention has an overall useful effect in various electronic devices, such as notebook computers, PDAs, mobile communication devices, electronic calculators, digital cameras, etc., which may be provided with a fingerprint sensor, a touch pad, and the like.

And while certain embodiments of the invention have been described and illustrated, it will be apparent that the invention may be embodied in various modifications by those skilled in the art.
