Portable medical bowel sound analysis, storage and playback system

technical field

The invention relates to the technical field of medical devices, in particular to a portable medical bowel sound analysis, storage and playback system.

Background technique

It is very important for a patient to go to the hospital for medical treatment at present. The doctor uses a stethoscope to listen to the bowel sounds for the patient to observe whether the patient's bowel sounds are normal. Now the most common method is that the doctor estimates, counts and diagnoses the bowel sounds of the patient with the help of a stethoscope. The stethoscope is mainly composed of a chest piece, a rubber tube and an ear piece. hear. Generally, experienced doctors need 10-20 minutes for manual diagnosis of bowel sounds, and people are prone to fatigue after a long time, but in fact, the effective auscultation time required by doctors is 2-3 minutes, which can basically reflect the symptoms. The diagnostic efficiency of the traditional auscultation method is very low. Doctors need to listen one by one, which lasts for a long time. In the case of many patients, not only a large number of doctors need to see the doctor at the same time, but also the patients will wait for a long time, which is not conducive to the rapid treatment of patients; Doctors must be in contact with patients, which may easily cause the source of disease transmission between doctors and patients; doctors use their own experience to estimate the tone and frequency of bowel sounds of patients, and it is inevitable that they will make judgment errors due to subjective and human factors.

Another method is that the doctor estimates, counts and diagnoses the patient's bowel sounds with the help of a pulse sensor, but the pulse sensor can only observe and record the number of bowel sounds, but cannot record the timbre of the bowel sounds, that is to say, it can only It reflects whether the rate of bowel sounds is normal or not, but cannot reflect the abnormal tone of bowel sounds caused by pathological changes, which will lead to the doctor's missed diagnosis of the patient's condition.

Contents of the invention

The purpose of the present invention is to provide a portable medical bowel sound analysis, storage, and playback system to solve the technical problems in the prior art such as low diagnostic efficiency, easy misdiagnosis and missed diagnosis, and high probability of infection.

A portable medical bowel sound analysis, storage, and playback system provided by the present invention includes a microphone, a controller, a memory, and a player; the microphone, the memory, and the player are all electrically connected to the controller; the microphone is used to transmit the bowel sound signal Convert it into an electrical signal, and transmit the electrical signal to the controller. The controller analyzes the electrical signal and converts it into a sound file and stores it in the memory. The player is used to play the sound file.

Further, the portable medical bowel sound analysis, storage, and playback system also includes a stethoscope chest piece, the microphone communicates with the stethoscope chest piece through a rubber tube, and the stethoscope chest piece is used to collect bowel sounds.

Further, the memory is provided with a USB interface, through which an external device is connected, and the files in the memory are output to the external device.

Further, the memory is provided with a wireless module, and the files in the memory are output to external devices through wireless transmission.

Further, the controller also includes a clock timing unit, which is connected to the liquid crystal display and displays the current time, bed number and timing status through the liquid crystal display.

A portable medical bowel sound analysis, storage, and playback system provided by the present invention uses a microphone to collect bowel sounds, converts bowel sound signals into electrical signals and transmits them to a controller, and the controller performs analog-to-digital conversion on the electrical signals and Automatically change the acquisition gain according to the strength of the signal, so that the collected bowel sounds are clear and less complicated, and then the processed bowel sounds files are stored in the memory and played by the player. The system is convenient for recovery and auscultation. You only need to send one set to each patient, and then take it back to the doctor for auscultation after two or three minutes. In this way, the bowel sounds information of multiple patients can be collected at the same time, and the complete bowel sounds information can be clearly dehybridized. , so that doctors can make a better diagnosis, not only has high diagnostic efficiency, but also saves a lot of time; it is especially suitable for the monitoring of bowel sounds in people with infectious diseases, without direct contact between doctors and patients, reducing the probability of infection for medical staff.
