Description
Technical field
The utility model relates to a kind of portable mobile wireless electrocardio hear sounds respiratory murmur collection demonstration and storage device.
Technical background
It is the method a kind of convenient and commonly used of diagnosis heart and lung diseases that auscultation of hear sounds respiratory murmur and electrocardiogram detect.Tradition stethoscope profile is small and exquisite, the use that is easy to carry, but often be difficult to capture some faint but very important biological sound, cause the doctor can't in time make diagnosis, delay diagnosis and treatment.Especially under rugged environment, on the in disorder scene of the accident, busy emergency room and noisy ambulance, it is almost impossible to use traditional stethoscope to diagnose effectively.And the existing heart state of an illness information of obtaining with the electronic stethoscope of gathering the hear sounds respiratory murmur merely is very limited, can't effectively distinguish ARR type.Simultaneously, the part arrhythmia is of short duration and accidental, if when outbreak can be gathered storage electrocardio, heart sound information rapidly, will improve diagnosis and treatment efficient greatly.Still there is not at present a kind of portable armarium can carry out hear sounds/respiratory murmur auscultation and electrocardiogram detection simultaneously, how to design a kind of rational in infrastructure and firmly get portable hear sounds respiratory murmur and the electrocardiosignal checkout equipment that the medical worker likes, being the important research project of pendulum in face of the scientific research personnel, also is one of extremely urgent work of armarium manufacturer.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of portable mobile wireless electrocardio hear sounds respiratory murmur acquisition terminal device, the wireless acquisition terminal of this device detects physiological signal by hear sounds/respiratory murmur pick off and EGC sensor, behind signal condition, by radio receiving transmitting module signal is launched, have LED light on the terminal, can indicating operating status, and can play hear sounds/respiratory murmur by boombox or earphone interface.
The purpose of this utility model is finished by following technical solution, and this device comprises hear sounds/respiratory murmur pick off, first and second low noise amplifiers, signal conditioning circuit, EGC sensor, high-pass and low-pass filter, A/D converter, CPU processor, keyboard, wireless transmission/reception module and LED display lamp; Described hear sounds/respiratory murmur pick off links to each other with described signal conditioning circuit by first low noise amplifier, join by described A/D converter and described CPU processor again, described EGC sensor links to each other with described high-pass and low-pass filter by second low noise amplifier, joins by described A/D converter and described CPU processor again; Described CPU processor is by wireless transmit/accepting module carries out wireless transmission of signal.
Described hear sounds/respiratory murmur pick off also is connected in an audio frequency power amplifier and speaker with after described signal conditioning circuit links to each other; Described CPU processor also is connected to described keyboard and LED light.
Described CPU processor is by described wireless transmit/accept module signal is transferred to wireless demonstration memory machine; Described wireless transmit/accept module is a bluetooth, or Zigbee.
Described wireless demonstration memory machine has earphone interface and boombox, also have can be in real time or playback show the LCD screen of electrocardiogram, hear sounds and respirophonogram.
The function of this utility model collection tradition stethoscope, electrocardiophonograph, electrocardiograph is an one, by being set, disturbs the filtering parameter decreasing environmental noise function, amplify hear sounds/respiratory murmur signal, gather surface electrocardiogram fast, and be connected with wireless demonstration memory machine by radio receiving transmitting module, display analysis electrocardiogram, hear sounds/respirophonogram are play hear sounds/respiratory murmur, and are had the function of real-time storage and related datas such as playback electrocardiogram, hear sounds/respiratory murmur in real time.Can substitute existing traditional stethoscope and electronic stethoscope clinically, particularly the medical worker to departments such as 120 emergency tenders, emergency department, cardiology department, intensive care units judges that fast conditions of patients is significant; Characteristics such as it has simple to operate, and is easy to carry.
Description of drawings
Fig. 1 is a system principle diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in detail: shown in Figure 1, this utility model mainly comprises: hear sounds/respiratory murmur pick off 1, first and second low noise amplifiers 2,5, signal conditioning circuit 3, EGC sensor 4, high-pass and low-pass filter 6, A/D converter 9, CPU processor 10, keyboard 11, wireless transmission/reception module 12 and LED display lamp 11; Described hear sounds/respiratory murmur pick off 1 links to each other with described signal conditioning circuit 3 by first low noise amplifier 2, join with described CPU processor 10 by described A/D converter 9 again, described EGC sensor 4 links to each other with described high-pass and low-pass filter 6 by second low noise amplifier 5, joins with described CPU processor 10 by described A/D converter 9 again; Described CPU processor 10 is by wireless transmit/accepting module 12 carries out wireless transmission of signal.
Described hear sounds/respiratory murmur pick off 1 also is connected in an audio frequency power amplifier 8 and speaker 7 with after described signal conditioning circuit 2 links to each other; Described CPU processor 10 also is connected to described keyboard 11 and LED light 13.
