Hereinafter, a patch type wireless stethoscope system according to the present invention will be described in detail with reference to the accompanying drawings. Unless defined otherwise, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs and, if conflict with the meaning of the terms used herein, It follows the definition used in the specification. Further, the detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

2 to 7, the patch type wireless stethoscope system according to an embodiment of the present invention attaches to a skin of a patient and collects a stethoscope sound in a human body, A transmitter (1) for wireless transmission; And a receiver 2 for receiving a stethoscope sound signal transmitted from the transmitter 1 and outputting the stethoscope sound signal so that it can be listened to and receiving the stethoscope sound signal of the patient transmitted from the transmitter 1, And a monitoring device 3 that can be displayed on the screen.

As described in the problems of the prior art, since the esophageal stethoscope used in the conventional surgery was inserted into the esophagus of the patient every time the operation was performed, the stethoscope sound, such as heart sounds and breath sounds, had to be collected, There was a fear of scarring and infection, and there was a problem that unnecessary expense was enormously expended because the disposable article was used and had to be discarded. In addition, since the esophageal stethoscope had to be inserted into the esophagus to listen to the stethoscope, there was a difficulty in continuously monitoring and observing the patient's stethoscope in the surgical situation. Accordingly, in the present invention, a stethoscope sound signal in the human body can be collected by easily attaching to the skin of a patient, and the sound can be transmitted by radio, thereby continuously monitoring the patient's stethoscope sound during the operation without using the esophageal stethoscope .

The transmitter 1 is attached to the skin of a patient, collects a stethoscope sound in the human body of the patient, processes the signal, and wirelessly transmits the signal to the receiver 2. The transmitter 1 has a small disc shape And a plurality of the staple sounds may be formed to be attached to various parts of the human body to collect stutter sounds.

The patch-type wireless stethoscope system is used to continuously monitor a patient's state by listening to a stethoscope sound such as a breathing sound or a heart sound during an operation to overcome many problems of the esophageal stethoscope described above. First, a user such as a doctor attaches the transmitter 1 to the chest of the patient and can be brought into close contact with the skin of the patient through the position fixing unit 15. [ Further, one of the above-described stethoscopic methods is selected to determine the position of the receiver 2. For example, the receiver 2 can be coupled to the head 101 of a conventional stethoscope, so that a stethoscope of a patient can be heard through a conventional stethoscope. The receiver 2 can be placed in a pocket or the like, And an earphone or the like is connected to the sound jack 231b of the receiver 2 to listen to the patient's stuttering sound through the earphone. The receiver 2 may be connected to a monitoring device 3 such as a PC to display the waveform of the patient's stuttering sound signal on the display unit 31 of the monitoring device 3, (31) to simultaneously display the stethoscope sound signals transmitted from both transmitters (1).

The stethoscope sound collected by the sound collector 11 of the transmitter 1 is amplified and filtered by the signal processor 12 and then converted into a digital signal At this time, the measurement mode adjustment module 141 and the volume adjustment module 143 filter the desired frequency band, adjust the volume, and transmit the adjusted frequency band to the receiver 2 through the wireless transmission unit 13. The stethoscope sound signal transmitted from the wireless transmission unit 13 is received by the wireless reception unit 21 of the receiver 2 and converted into an audible analog signal by the signal processing unit 22 and amplified to the output unit 23 ). As described above, when the receiver 2 is coupled to the head 101 of the existing stethoscope, the stethoscope sound output through the speaker 231a can be heard through the existing stethoscope. The sound jack 231b, So that it is possible to listen even with an earphone. At this time, the stethoscope sound selecting module 241 can output a stethoscope sound transmitted from one of the transmitters 1 of both the transmitters 1, or can transmit a stethoscope sound transmitted from both transmitters 1, May be output. When the monitoring device 3 is connected to the receiver 2 through the connection terminal 263a of the receiver 2, the change of the stethoscope sound can be monitored through the display unit 31 of the monitoring device 3 . At this time, the monitoring device 3 simultaneously displays both stethoscopic sound signals through the display unit 31, and a stethoscope sound signal is stored in the storage unit 33.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as falling within the scope of.
