Description

Technical Field

[0001] The present invention relates to the technical field of stethoscopes, and more particularly to a bowel sound auscultation device capable of avoiding noise interference. Background Art

[0002] Auscultation has been used as a non-invasive examination for centuries. Bowel sounds are one of the most important auscultatory components of an abdominal examination. Disorders of intestinal motility, such as chronic constipation and irritable bowel syndrome, are highly prevalent. However, the diagnosis of these conditions relies heavily on subjective patient experience and is significantly influenced by the patient's own experience. Tests that objectively assess normal intestinal motility are rare and cumbersome to perform. For example, a colon transit test requires multiple abdominal radiographs, and intestinal manometry requires the insertion of a manometric device. Studies have also found that some organic diseases, such as Crohn's disease and ulcerative colitis, are also associated with abnormal intestinal motility. These abnormalities can be reflected by bowel sounds, which can serve as objective evidence to aid in the diagnosis of these conditions. Because bowel sounds are irregular and have been shown to exhibit a periodicity of approximately 80-150 minutes, auscultation is often performed over a longer period to fully capture their characteristics.

[0003] Traditional stethoscopes for auscultating bowel sounds have shortcomings such as a limited ability to monitor bowel sounds over extended periods, subjective physician judgment, and an inability to fully understand the signal characteristics. The advent of electronic stethoscopes can overcome these shortcomings. However, electronic stethoscopes also have drawbacks. The recording process inevitably picks up ambient noise, which can significantly interfere with bowel sound analysis. Therefore, a bowel sound auscultation device that avoids noise interference is needed. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bowel sound stethoscope device that avoids noise interference. Through the setting of a front sound-isolating abdominal belt, a fixed sound-isolating abdominal belt and an adhesive sound-isolating abdominal belt, the stethoscope body can be fixed, and external noise can also be blocked. With the help of wireless transmission of the wireless network card and wireless charging of the battery, long-term measurement can be performed to solve the problems arising in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a bowel sound auscultation device that avoids noise interference, comprising a stethoscope body, the stethoscope body comprising a sound pickup head, a front sound-insulating abdominal band provided on the rear side of the sound pickup head, an inspection hole being provided through the front side of the front sound-insulating abdominal band, a rear end of the sound pickup head passing through the inspection hole and extending to the rear side of the inspection hole, elastic bands being fixed on both sides of the front sound-insulating abdominal band, a fixed sound-insulating abdominal band and an adhesive sound-insulating abdominal band being fixed on one end of the two elastic bands away from the front sound-insulating abdominal band, respectively, and Velcro being fixed on the front side of the fixed sound-insulating abdominal band and the rear side of the adhesive sound-insulating abdominal band;

Two second mounting grooves are provided on the side of the movable plate away from the sound insulation shell, and the two second mounting grooves correspond to the positions of the two positioning holes on the left and right respectively. Through the cooperation of the two sound insulation shells, the sound pickup head can be blocked and sealed to prevent external noise from affecting the measurement results;

[0008] The diameter of the inspection hole is smaller than the diameter of the rear end of the sound pickup head, and the diameter of the inspection hole is larger than the diameter of the front end of the sound pickup head. By setting the diameter of the inspection hole to be larger than the front end of the sound pickup head and smaller than the diameter of the rear end of the sound pickup head, the rear end of the sound pickup head can be fixed and squeezed, so that the sound pickup head is tightly attached to the patient's abdomen, preventing the sound pickup head from moving out through the inspection hole.

[0013] The present invention sets the sound pickup head in the inspection hole, and then fixes the front sound insulation belly band to the patient's abdomen with the help of a fixed sound insulation belly band, an adhesive sound insulation belly band and a Velcro. Since the inspection hole is smaller than the rear end of the sound pickup head, the elastic force of the front sound insulation belly band can squeeze and fix the rear end of the sound pickup head, while the front end of the sound pickup head will extend through the inspection hole, thereby avoiding the gap between the front sound insulation belly band and the skin due to the volume of the stethoscope body, and also improving the comfort of the patient when using it. At the same time, since the sound pickup head is a directional microphone, it only collects sound signals perpendicular to the contact surface. Wireless network card The setting can transmit the collected sound signals wirelessly in real time. The overall structure can fully reduce the interference of environmental noise during the sound collection process, and is not limited to the use of scenes and venues. Then, with the help of the recording function of the stethoscope body itself in the present invention, the audio collected by the pickup head can be recorded to facilitate the doctor to listen, thereby improving the adaptability of the present invention. In addition, the stethoscope body can be fixed by setting the front sound insulation belly belt, the fixed sound insulation belly belt and the adhesive sound insulation belly belt. With the help of wireless transmission of the wireless network card and wireless charging of the battery, long-term measurement can be carried out.

[0014] The present invention drives the sound insulation shell on the movable plate to be sleeved on the outside of the front end of the pickup head through the extension force of the movable plate, and the arrangement of the two sound insulation shells can effectively block external noise to prevent external noise from affecting the measurement results. At the same time, the two ends of the rubber tube can be separated from the mounting plate and the movable plate respectively by rotating the threaded sleeve. After separation, the user can take out the spring in the rubber tube for replacement. After replacement, the rubber tube is fixed by the cooperation of the threaded sleeve with the first mounting groove and the second mounting groove. The overall result is simple to operate and easy to use, which can effectively improve the sound insulation performance of the present invention and also facilitate the replacement of the spring.
