Description

Wireless digital intestinal sound monitoring system

This creation is about a health monitoring system, especially a wireless digital intestinal sound monitoring system.

When the human stomach squirmes, it emits a sound called a bowel sound or a bowel sound (hereinafter referred to as bowel sound). The frequency, tone and sound level of the bowel sound can reflect the healthy state of the human stomach. Traditionally, the diagnosis of bowel sounds is performed by a physician directly auscultating the abdomen of the patient with a stethoscope to determine the gastrointestinal condition of the patient by the frequency, tone and sound of the patient's bowel sounds. For example, the frequency of intestinal peristalsis in healthy humans is about 3 to 5 times per minute, and if it exceeds 10 times, it may be acute gastroenteritis. Alternatively, after major abdominal surgery, 50% of patients will develop intestinal obstruction with varying degrees of severity, so such patients need to continuously observe and monitor gastrointestinal motility. However, traditional gastrointestinal monitoring must rely on the physician to directly observe the gastrointestinal motility of the patient through the stethoscope, and use the number of bowel sounds emitted by the patient's gastrointestinal motility and the level of the tone to determine whether the gastrointestinal tract is moving. The disadvantage of traditional bowel auscultation is that the doctor must continuously measure the time of the stethoscope to determine whether the patient's gastrointestinal motility is different, which makes the diagnosis extremely inconvenient. In addition, the quality of auscultation and the training, experience and environment of the physician It is difficult for doctors to make a more objective assessment of the patient's gastrointestinal motility due to changes in the patient's abdominal condition. Moreover, in the traditional auscultation process, a doctor or a nurse can only test one patient, and the use of manpower is not economical. Therefore, the author believes that it is necessary to develop a bowel sound monitoring system to simultaneously monitor the abdominal bowel state of a plurality of patients at the same time, to more objectively judge the patient's gastrointestinal motility, and to save the consumption of medical staff.

In view of the shortcomings of the prior art, the present author has created a wireless digital intestinal sound monitoring system, including: a bowel sound sampling group, including a bowel sound collector, for being placed on the abdomen of the human body to sense sound, so that The intestinal sound sampling group generates a first analog sound; a noise sampling group includes an environmental sound collector for being external to the human body to receive ambient sounds around the human body, so that the noise sampling group produces a second analogy An audio filtering processor electrically connected to the intestinal sound collector and the environmental sound collector, wherein the audio filtering processor writes an audio filtering program for the audio filtering processor to execute: according to the second Analog audio, in the first analog audio, the portion of the sound collected by the noise sampling group is removed to generate a third analog audio; and the analog digital signal conversion unit is electrically connected to the audio filtering processor. For converting the third analog audio into a third digital audio; a wireless signal transmitter electrically connecting the analog digital signal conversion unit, For transmitting the third digit audio; a host, comprising a wireless signal receiver, is connected to the wireless signal transmitter, the host is provided with a processor electrically connected to the wireless signal receiver, and electrically connected to the processing a warning device, the processor is provided with a first warning program for the processor to perform: processing the third digit audio to obtain a bowel sound frequency value, when the intestinal sound frequency value falls within a preset range In addition to the value, the alert is controlled to issue an alert. With the above settings, the patient's bowel movements can be transmitted back to the host. The host system can determine whether the patient's bowel movement frequency is abnormal. If an abnormality occurs, a warning is sent to notify the medical staff. It is not necessary for the staff to take a long time to test the bowel sound of a patient to save the labor consumption of the medical staff. In addition, with this creation, the medical staff can remotely monitor the peristalsis of multiple patients at the host. In addition, by setting the noise sampling group and the audio filtering processor, unnecessary noise (ambient sound, heart sound, etc.) in the first analog audio obtained by the intestinal sound sampling group can be filtered to make the host The received bowel sounds are less susceptible to distortion, thereby improving the accuracy of the host system and medical personnel in interpreting the audio data.

The construction, features and embodiments of the present invention will be described with the aid of the drawings, and the reviewers will have a better understanding of the present invention. When the human intestines move, it will make a sound because of the friction and collision of fluid in the intestine, which is called bowel sound or intestinal percussion (hereinafter referred to as bowel sound). The frequency, tone and sound level of the bowel sound can reflect the healthy state of the human stomach. Referring to the first figure, this creation is about a wireless digital intestinal sound monitoring system, including: a bowel sound sampling group (1): including a bowel sound collector (11). The bowel sound collector (11) can be an attached condenser microphone for attaching to the abdomen of the human body to sense sound so that the bowel sound sampling group (1) generates a first analog sound. The intestinal sound collector (11) is mainly for collecting human intestinal sounds, and the number thereof is preferably plural to increase the range of the sound. The detailed structure of the condenser microphone is a well-known technique and is not intended to be within the scope of the present invention. A noise sampling group (2): comprising an ambient sound collector (21), the ambient sound collector (21) can be a condenser microphone for external environment of the human body to receive environmental sounds around the human body. In a preferred embodiment, the noise sampling group (2) may further include a heart sound collector (22), which may be an attached condenser microphone for attaching to The human chest is used to sense the heart sound of the human body. In another embodiment, the noise sampling group (2) may further include a stomach sound collector (23) for sensing the skin of the human stomach to sense the sound of the human stomach. The noise sampling group (2) can generate a second analog audio by synthesizing the audio sound collector (21), the heart sound collector (22) and the sound collected by the stomach sound collector (23). So that the second analog audio includes the ambient sound collector (21), the heart sound collector (22), and the sound generated by the stomach sound collector (23) as an audio filter processor to be described later. (3) The basis for filtering the first analog audio. An audio filtering processor (3): electrically connected to the intestinal sound sampling group (1) and the noise sampling group (2). The audio filtering processor (3) writes an audio filtering program for the audio filtering processor (3) to perform: according to the second analog audio, the first analog audio belongs to the noise sampling group (2) The part of the collected sound is removed, and a third analogy is produced. That is, according to the waveform of the second analog audio, the portion of the first analog audio that matches the second analog audio waveform is removed to generate the third analog audio. In the actual collection of the sound of the bowel sound, the first analogy sound collected by the bowel sound sampling group (1) may receive the environmental sound around the patient, the heart sound of the patient itself, and the stomach in addition to the patient's bowel sound. Creepy sound. By means of the audio filtering program, the noise (second analog audio) collected by the noise sampling group (2) can be removed from the first analog audio to leave a relatively pure intestinal audio (third analogy) Audio). The analog digital signal conversion unit (4) is electrically connected to the audio filtering processor (3) for converting the third analog audio into a third digital audio for processing and interpretation by a system to be described later. A wireless signal transmitter (5): electrically connected to the analog digital signal conversion unit (4) for transmitting the third digital audio. The signal sent by the wireless signal transmitter (5) can be a wifi signal or a Bluetooth signal. A host (6): includes a wireless signal receiver (61) coupled to the wireless signal transmitter (5). As shown in the second figure, the wireless signal receiver (61) can be a wifi router or a Bluetooth signal receiving end for simultaneously connecting the wireless signal transmitters (5) of the plurality of patients. The host is provided with a processor (62) electrically connected to the wireless signal receiver (61), and a warning device (63) electrically connected to the processor (62). The warning device (63) can be a sounder, a warning light, a warning screen, and the like. The processor (62) is provided with a first alert program for the processor (62) to perform: processing the third digit audio to obtain a bowel sound frequency value, when the bowel sound frequency value falls within a preset In addition to the range value, the alerter (63) is controlled to issue an alert. Among them, it must be stated that the frequency of occurrence of the bowel sound refers to the number of occurrences of bowel sounds per unit time in the third digit audio, so the unit is the number of times/time, and the larger the value represents the frequency of intestinal peristalsis The higher the bowel movement, the more intense it is. For example, suppose the processor (62) has a preset range value of bowel peristalsis rate of 2 to 8 times per minute. When the alert program processes the third digit audio, it is determined that the patient's bowel sound frequency is every minute. 15 times, the alarm (63) is controlled to act to give a warning effect. In a preferred embodiment, the processor of the host (6) is further electrically connected to a storage unit (64) for storing the digital audio file received by the processor (62) to establish a bowel movement of the patient. A database of information to help medical staff grasp the complete case of the patient. With the above settings, the patient's bowel movements can be transmitted back to the host (6). The system of the host (6) can determine whether the frequency of bowel movements of the patient is abnormal, and if there is an abnormality, a warning is issued. Inform the medical staff so that the medical staff does not need to spend a long time to test the bowel sound of a patient to save the labor consumption of the medical staff. Moreover, with the present creation, the medical staff can remotely monitor the intestinal peristalsis of a plurality of patients at the host (6). For example, after a major intra-abdominal surgery, there is a 50% chance of intestinal obstruction, so surgical patients often need to monitor their peristalsis for a long time. Usually, the hospital will arrange multiple patients for surgery one day. At this time, with the creation of the bowel sound monitoring system, a physician or a nurse can continuously monitor the gastrointestinal tract of multiple patients simultaneously on the host (6). Whether the peristaltic rate is normal or not, greatly improving the utilization efficiency of the medical staff. In addition, by the setting of the noise sampling group (2) and the audio filtering processor (3), unnecessary noise in the first analog audio obtained by the intestinal sound sampling group (1) can be filtered (ambient sound, Heart sounds, etc., so that the intestinal audio signals received by the host are more difficult to be distorted, thereby improving the accuracy of the host system and the medical staff to interpret the audio data. In a preferred embodiment, between the analog-to-digital conversion unit (4) and the wireless signal transmitter (5), a digital signal processor (7) is further provided for inputting the analog-to-digital conversion unit (4). The digital signal is converted by Fourier transform and its time domain is converted to the frequency domain to provide subsequent systems to interpret different messages.
