    Electronic stethoscope system using personal digital assistant
    [15] The present invention relates to an electronic stethoscope system using a PDA, and more particularly, to an electronic stethoscope system for converting a stethoscope sound into an electrical signal using an electronic stethoscope and processing it into a visual form using a PDA and transmitting it to a remote computer. It is about.
    [16] In general, a stethoscope is a device for checking a doctor's health by listening to a living body sound or a heart sound generated from an internal organ of a human body. The stethoscope is composed of a biological sound collecting unit for collecting biological sounds in the human body, an earpiece for allowing the collected heart sounds to be heard by a doctor's ear, and a tube required as a heart sound transmission path between the heart sound collecting unit and the earpiece.
    [17] However, the conventional stethoscope is not only difficult to hear the sound of the subtle changes of the human body because it is to listen to the biological sound of the moment when the doctor consults, too much noise can not be accurately sensed, and is judged by the doctor's subject, there are many false Another problem was difficult to judge.
    [18] In order to solve this problem, an electronic stethoscope has been proposed. The electronic stethoscope has a configuration in which the collected sound is converted into an electrical signal using a microphone, and then amplified and filtered to be output through the speaker.
    [19] Since the conventional electronic stethoscope simply amplifies the sound by converting the sound into an electrical signal, it was difficult to grasp the sound passing by at a moment. Thus, in order to solve this problem, an electronic stethoscope having a configuration showing a sound wave by connecting an electronic stethoscope to a computer has been proposed, but it has a disadvantage in that it is inconvenient to use and inconvenient to carry because it must be connected to a computer.
    [20] The present invention has been made in view of such a point, and an object of the present invention is to provide an electronic stethoscope system that is not only portable but also enables accurate examination.
    [21] Another object of the present invention is to provide an electronic stethoscope system capable of visually analyzing and showing the measured stethoscope sound.
    [22] Another object of the present invention is to provide an electronic stethoscope system capable of storing and analyzing measured stethoscope sound data in a remote computer.

    [28] The microphone 110 converts the stethoscope sound of the patient into an electrical signal. The converted stethoscope sound signal is amplified to an appropriate magnitude in the amplifier 120, and then the noise is removed using the filter 130. The doctor may listen to the noise canceled stethoscope using earphones connected to the earphone interface 140. Alternatively, by installing a speaker instead of the earphone interface 140, it is also possible to listen directly to the stethoscope sound without using the earphone.
    [29] The noise canceled stethoscope is also converted into a digital signal using an analog to digital converter (ADC) 150. The converted digital stethoscope signal is transmitted to the PDA through the PDA interface 160. The connection between the electronic stethoscope 100 and the PDA 200 may use a wired interface such as RS-232C, RS-422, or USB, or may use a wireless interface such as an infrared interface or a blue tooth.
    [30] It is also possible to send an analog signal directly to a PDA without the ADC 150 and to convert it to a digital signal from the PDA.
    [31] Next, the internal structure of the PDA 200 will be described with reference to FIG. 3.
    [32] The user selects a desired function or inputs a desired content by using the input unit 220. A keypad, a pointer, etc. may be used as the input unit 220, but is not limited thereto.
    [33] Content input by the user is processed by the controller 210 and displayed on the display 230. As the display unit 230, various display elements such as a liquid crystal display (LCD), a light emitting diode (LED), an electroluminescent display (ELD), and the like may be used.
    [34] The memory 240 stores various programs necessary for the operation of the PDA 200 and various data necessary for operating the programs. As the memory 240, various types of memory devices such as static random access memory (SRAM), dynamic random access memory (DRAM), read-only memory (ROM), and flash memory may be used.
    [35] The external interface 250 is used to connect the PDA 200 with various external devices such as a printer, a computer, a mobile phone, and the like. As the external interface 250, a wired interface such as RS-232C, RS-422, or USB may be used, or a wireless interface such as an infrared interface or a blue tooth may be used.
    [36] The wireless communication unit 260 is used to connect to a telephone network or the Internet using the PDA 200 as an option. The wireless communication unit 260 preferably uses a wireless modem for connection with a CDMA or GSM mobile communication network, but is not limited thereto.
    [37] The controller 210 controls a peripheral device according to a program stored in the memory 240 and performs various operations. In the present invention serves to receive a stethoscope signal from the electronic stethoscope 100 through the external interface 250 to perform a variety of operations to display through the display unit 230. Also, it transmits the stethoscope sound signal measured to the external computer 300 through the external interface 250 or the wireless communication unit 260 or downloads and displays the stethoscope sound signal stored in the external computer 300. Do it.
    [38] Next, the operation of the control unit 210 will be described with reference to FIG. 4.
    [39] The user may use the electronic stethoscope system by driving the software for the electronic stethoscope system embedded in the PDA 200. The electronic stethoscope system software built into the PDA 200 has three functions.
    [40] First, a function of storing a stethoscope sound obtained using the electronic stethoscope 100 through the external interface 250 from the electronic stethoscope 100 is stored in the memory 240, and the second is stored in the memory 240. It is a function that calculates the waveform, spectrum, etc. from the auscultation stethoscope signal, and the third is a computer (using the wireless communication unit 260 or the external interface 250 to the stethoscope signal stored in the memory 240) 300 or upload a stethoscope signal stored in the computer 300.
    [41] When the user connects the electronic stethoscope 100 to the external interface of the PDA 200 and selects the function of acquiring and storing the stethoscope sound (recording of the hearing sound), the controller 210 receives the stethoscope sound through the external interface 250. The signal is received and temporarily stored in the memory (step S110). The controller 210 compresses the received stethoscope sound signal using an audio compression algorithm such as ADPCM, MP3, or H.723 and stores it in the memory 240 (step S120). The controller 210 also stores information such as a date measured and a patient name when the compressed signal is stored in the memory 240 (step S130). As a method of storing such information, a method of using such information as a file name when storing compressed stethoscope sound (eg hongkildong010830.mp3), and by setting up a separate database for storing such information, the name of the stethoscope file and the measured There are many ways to store dates, patient names, and other information in this database. This information can be used later when searching for a desired stethoscope file.
    [42] When the user selects a function (listening sound display) for viewing the characteristics of the stored stethoscope sound file, the controller 210 displays a stethoscope sound file selection screen so that the user can select the stored stethoscope sound file (step S210). When the user selects the stethoscope file, the control unit 210 loads the file, decompresses the file, and calculates characteristics of the waveform, spectrum, and heart rate of the stethoscope (step S220). The calculated result is displayed on the screen (step S230).
    [43] An example of such a screen is shown in FIG. In FIG. 5, the upper window shows the waveform of the stethoscope sound over time, the middle window shows the heart rate change trajectory over time, and the lower window shows the spectrum of the stethoscope sound. The user may repeatedly view a desired section on the screen of FIG. 5 or enlarge a specific section.
    [44] In the above example, the stored stethoscope sound file is called to display various characteristics, but it is of course possible to display the various characteristics corresponding to the stethoscope sound while acquiring the stethoscope sound.
    [45] When the user selects a function of uploading or downloading a stethoscope sound file (wired or wireless transmission) by wire or wireless, the controller 210 connects to the computer or the server 300 using the wireless communication unit 260 or the external interface 250 ( Step S310). The method of connecting to the computer or server 300 may be connected via wireless Internet, may be connected through a telephone line using a modem, or may be directly connected through Bluetooth or infrared communication. In this case, it is also possible to log in using an ID and a password so that only a legitimate user can access.
    [46] A user connected to the computer 300 uploads a stethoscope sound file stored in the PDA 200 or downloads a stethoscope sound file stored in the computer (step S320). When the file transfer is completed, the controller 210 terminates the connection with the computer 300 (step S330).
    [47] While the invention has been described using some preferred embodiments, these embodiments are illustrative and not restrictive. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention and the scope of the rights set forth in the appended claims.
