As described in detail above, the present invention, as indicated by its constituent requirements, converts a weak pulse vibration of a human into an electric vibration by simply holding the mobile phone by the air pad sensor 8, and the signal is converted into a noise frequency by a filter. The band can be removed and only the pulse waveform can be taken out to count the pulse rate. Further, the pulse rate can be counted only by putting the fingertip on the optical element and transmitting or reflecting the light element so as to count the pulse rate without putting the pulse on the palm of the hand and keeping it quiet.

Can be sent to the destination quickly and reliably without using.

  The present invention holds a device and sandwiches a urethane or rubber-like pad in which air is sealed between the device and the palm, and converts a weak pulse vibration of a human into an air vibration inside the pad. The mobile phone incorporates an air pat sensor that converts air vibrations into electrical signals and detects the pulse.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing an embodiment in which the present invention is applied to a mobile phone type pulse meter. In FIG. 1, the mobile phone 1 is usually held with the back surface of the key switch surface 3 placed against the palm 2.
FIG. 2 is a cross-sectional view showing the inside from the lateral side of the mobile phone 1 incorporating the air pad sensor 8.
In the mobile phone 1, a transparent glass 5 serving as a display window and a key switch 3 for operating the mobile phone are fitted on the surface of the case 4. A recess 6 is provided on the back surface of the key switch surface 3 of the case 4, and an air pad sensor 8 is attached with a screw 7. On the right side of the air pad sensor 8, there are provided a well-known mobile phone device 10 including a pulse counter device 9 which is the heart of the pulse meter, and between these and the transparent glass 5, the operation of the mobile phone is performed. In addition, a liquid crystal display panel 11 for displaying the pulse rate is provided.

FIG. 3 is a front view of the liquid crystal display panel 11. The liquid crystal display plate 11 is provided with a time display unit 12, a battery status display 13, a radio wave status display 14, and a pulse rate display unit 15.
FIG. 4 is an enlarged view of the air pad sensor 8.
Between the plate 16 and the fine pressure sensor 17, an air pad 18 in which air for detecting fine vibration transmitted from a human palm 2 is sealed with a urethane sheet or a rubber sheet is installed. The micro pressure sensor 17 converts the vibration of the air in the inner sealed portion of the air pad 18 into an electrical signal. A cover 19 that protects the surface of the air pad 18 is provided on the left side of the air pad 18, and the air pad 18 is deformed when the palm 2 comes into close contact with the cover 19.

FIG. 5 is a cross-sectional view of the fine pressure sensor 17 and the air pad 18.
In FIG. 5, the structure of the fine pressure sensor 17 is that a piezoelectric element 23 is incorporated in the housing 20, and the gap is filled with a rubber packing 24 so that air does not leak from the gap between the housing 20 and the piezoelectric element 23. The packing 24 is held by the plate 25. As a result, the inner chamber 21 and the outer chamber 22 of the housing 20 are completely partitioned by the piezoelectric element 23.

  In FIG. 5, the sealed portion of the air pad 18 and the inner chamber 21 of the housing 20 of the fine pressure sensor 17 are connected by a hole 26 of the housing 20. When the cellular phone type pulsometer 1 is gripped by the palm 2, the palm 2 comes into close contact with the cover 19 and the air pad 18 is pressed. At this time, pressure is applied to the air in the sealed portion of the air pad 18, and the air in the sealed portion is in a state where air vibration is generated even with a slight vibration of the palm 2. The air vibration is transmitted to the inner chamber 21 through the hole 26 to vibrate the piezoelectric element 23. Similarly, the pulse vibration emitted from the palm 2 is transmitted to the air in the sealed portion of the air pad 18, and the pulse vibration is converted into air vibration. The air vibration vibrates the piezoelectric element 23, converts it into an electrical signal, and passes through the cable 27. Then, an electrical signal is output to the pulse counter device 9.

FIG. 6 is a block diagram showing a circuit of the pulse counter device 9 according to the present invention.
The pulse counter device 9 is a circuit that processes a vibration waveform from the piezoelectric element 23 and calculates a human pulse rate. In FIG. 6, the pulse waveform detected by the piezoelectric element 23 is high impedance. The pulse waveform of high output impedance is input to the pulse counter device 9 through the cable 27, converted from high impedance to low impedance by the impedance converter 28, and output to the next circuit.

  Reference numeral 29 denotes an amplifier, which needs to be amplified because the pulse amplitude is very small. Reference numeral 30 denotes a filter, which passes the frequency band of 1.0 to 4.0 Hz of the pulse amplitude and removes other noise frequency bands. As a result, a pulse waveform such as a triangular wave is output for one pulse. By converting a pulse waveform such as a triangular wave into a square wave by pulse conversion 31, a pulse count pulse of one square wave is output for one beat.

Next, details of a mechanism for counting human pulses will be described.
Human blood is pumped out to blood vessels throughout the body by the pulsation of the heart. When the blood is pumped into the blood vessel, a slight vibration of the blood circulation is emitted. Such a slight vibration generated by the heartbeat is detected from the palm of the hand and the pulse rate is counted.

  In FIG. 7, when the mobile phone 1 is held in the human palm 2 and the blood is pumped out to the blood vessel by the heartbeat, the mobile phone 1 is built into the mobile phone 1 due to the slight vibration generated from the palm 2. Air in the sealed portion of the air pad 18 causes air vibration and is transmitted to the piezoelectric element 23 through the hole 26. The piezoelectric element 23 that has received the vibration converts air vibration into a high-impedance electric signal, and is input to the impedance converter 28 of the pulse counter device 9 via the cable 27.

  The electrical signal input to the pulse counter device 9 is converted to a low impedance by the impedance converter 28 because of the high impedance. After the conversion, since the pulse waveform is very small, it is amplified by the amplifier 29, and noise components other than 1.0 Hz to 4.0 Hz are removed by the filter 30. A signal output from the filter 30 is shown in FIG. In the present invention, when blood is sent out to a blood vessel due to the pulsation of the heart, an amplitude waveform of 1.0 Hz to 4.0 Hz, such as a triangular wave shown in FIG. 7, is repeatedly output.

  A pulse waveform such as a triangular wave is input to the pulse converter 31 and converted into a square wave shown in FIG. That is, when blood circulation (one pulse) occurs due to one beat of the heart, one square wave is output from the pulse counter device 9.

  The cellular phone device circuit board 10 to which the square wave of the pulse count pulse is inputted from the pulse counter device 9 calculates the count number of the square wave inputted in one minute from the interval time of the inputted square wave, and the liquid crystal display The pulse rate 15 of the board 11 is displayed.

  By the above air vibration-electrical signal conversion method, a human pulse transmitted from the palm 2 can be extracted simply by incorporating an air pad sensor 8 and a pulse rate counter device 9 in a case 4 such as a general mobile phone 1. Can count the pulse rate.

  Next, a structure for transmitting the counted pulse rate with a mobile phone will be described. In FIG. 6, it is a block diagram which shows the part which transmits the pulse count pulse output from the pulse converter 31 to external recipients, such as a medical center. In FIG. 6, the pulse rate output from the pulse converter 31 is temporarily stored in the work memory 32.

  The pulse data stored in the work memory 32 is sent as a part of the display data in the frame memory 33 for storing the display data of the liquid crystal display panel 11, and after being stored therein, as shown in FIG. The pulse rate is displayed.

  On the other hand, the pulse data stored in the work memory 31 is referred to as mail attachment data from the Internet mail transmission / reception means 34, processed as transfer data together with other telephone transmission data, and then transmitted from the mobile phone to the Internet or the like. The packet is transferred to the network 35.

  As mentioned above, although this invention was demonstrated by the above-mentioned embodiment, various deformation | transformation and application are possible within the range of the main point of this invention, and these deformation | transformation and application are not excluded from the scope of the present invention.

  Data such as pulse and blood pressure of home patients can be easily sent to a medical institution such as a medical center several times a day using a mobile phone. Therefore, the present invention is optimally applied to a medical system.
