Abstract

The invention discloses an auscultation device for screening abnormal noise of internal arteriovenous fistula in hemodialysis, and relates to the technical field of medical detection equipment. The auscultation device comprises a sound wave receiving and listening device, conduction equipment, an anti-interference device and an internal arteriovenous fistula noise sound wave acquisition layer, wherein the sound wave receiving and listening device comprises a noise reduction earflap and a sound wave processor; the sound wave processor is located in the noise reduction earflap; and the edge of the sound wave processor is fixedly connected to the inner wall of the noise reduction earflap. According to the invention, the sound wave receiving and listening device is utilized to amplify a soundsignal received by a doctor, so that arteriovenous sound can be clearly transmitted to the ears of the doctor, and an accurate sound basis is provided for the final judgment of the doctor; and the internal arteriovenous fistula noise sound wave acquisition layer is matched with the anti-interference device to quickly transmit arteriovenous sound information into the sound wave receiving and listening device without external interference, so that the effectiveness and comprehensiveness of sound data are kept.

Description

technical field [0001] The invention relates to an arteriovenous auscultation device, relates to the technical field of medical testing equipment, in particular to an auscultation device for screening abnormal murmurs of hemodialysis arteriovenous fistula. Background technique [0002] Arteriovenous auscultation is an auxiliary examination method to check whether the arteriovenous pulse is normal. If there is suspected arteriovenous disease, the carotid artery (the inner edge of the sternocleidomastoid muscle, the height of the upper edge of the thyroid cartilage), the clavicle Auscultate the inferior artery, renal artery, abdominal aorta, brachial artery, femoral artery, etc. Under normal circumstances, only two heart sounds consistent with S1 and S2 can be heard on the carotid artery and supraclavicular artery, which are called normal arterial sounds. Arterial murmurs are more common in peripheral arteries, and can also be found in pulmonary arteries and coronary arteries...
