During the method concerning the examination of the intra-uterine condition f the foetus, the mechanical vibrations induced by the heart of the foetus, together with other vibrations coming from the body of the expectant mother, are sensed by the at least one electro-mechanical transformer placed on the body surface of the expectant mother, the detected vibrations are transformed into electrical signals; the electrical signals so received are led to the signal processing units and processed, during which the electrical signals are pre-amplified by manually adjustable amplification of automatic amplification control; the frequencies including the heart sound of the expectant mother are removed from the amplified electrical signals of the perceived vibrations by active band filtering; the signal level reduction due to band filtering is compensated for by amplification; the filtered signal is subjected to further transformation before processing, so that it is modulated to a carrier frequency in the range of 5.5-6.5 kHz, and led to the signal processing unit that way; in the signal processing unit, first the modulated signal is demodulated, then it is processed. A device suitable for implementing the method comprises the following main components: - an elastic belt that can be fixed on the abdomen of the expectant mother; - at least one electro-acoustic transducer (22) and filtering and signal conditioning grade (22) detecting mechanical vibration placed in the belt, connected to a communication device (21), preferably a smart phone, preferably through wireless, e.g. Bluetooth, connection; Between the electro-acoustic transducer (22) and the communication device (21), a band filter is inserted, that is designed as band filter cutting off sharply the frequencies of under around 20 Hz and above 200 Hz, and 70 Hz and 300 Hz, respectively, including also the heart sound of the expectant mother. The computer program product to be run on the device, e.g. the smart phone, processes the measured signals, displays them visually, and makes proposals and shows trends to the user based on the processed signals.

摘要:
Systems and methods are provided for extracting hemodynamic information, optionally employing portable electronic devices with optional User Interface (UI) features for system implementation. The systems and methods may be employed for acquiring hemodynamic signals and associated electrophysiological data and/or analyzing the former or both in combination to yield useful physiological indicia or results. Such hardware and software is advantageously used for non-invasively monitoring cardiac health.

A stethoscope head with adjustable audio frequency includes a head body (14), a diaphragm (12) and a fastener (11). The diaphragm (12) is provided with an annular step (142) and a footing (122). The diaphragm (12) is disposed on a sound collecting surface (5) at the front side of the head body (14) and is fixed on the head body (14) by the fastener (11). The outer marginal part of the front side of the head body (14) is provided with the annular step (142), and a screw thread (143) is provided on a step surface of the annular step (142). An annular groove (144) is provided at the sound collecting surface (5) inside the annular step (142), and the inner surface (148) of the annular groove (144) and the bottom surface (147) of annular groove (144) form an obtuse angle ³. The diaphragm footing (122) is disposed in the annular groove (144). The fastener (11) includes a ring A and a ring B whose upper surfaces are located at the same horizontal plane. The ring B is place in the ring A and the external diameter of the ring B is the same as the internal diameter of the ring A. An inner wall (115) of the ring A is provided with a screw thread (111) which matches with the screw thread (143) on the step surface. The stethoscope head of the invention is convenient to assemble and the sound effect can be adjusted continuously.
摘要:
A detection head of a stethoscope comprises a detection head body (1, 2, 8) and a sound guiding conduit in the detection head body (1, 2). The sound guiding conduit comprises a sound collecting surface (12, 23), a sound guiding pore (D), and a lateral sound guiding aperture (4). The sound collecting surface (12, 23), the sound guiding pore (D), and the lateral sound guiding aperture (4) are disposed on the detection head body (1, 2, 8), and in combination with each other. At least a part of the detection head body (1, 2, 8) is made of a second density material. The density of the material of a sound guiding layer (3, 5, 6, 7, 9A) on the sound collecting surface (12, 23) is greater than that of the second density material. The detection head (1, 2, 8) of a stethoscope has advantages of light in weight, low in cost, and not affecting the sound-listening performance.

A diagnostic apparatus includes a stethoscope, an electrocardiac detector, a control unit, and an external unit. A sound detector is a chest piece to make contact with a patient's skin, and includes a first detector to detect a relatively high frequency and a second detector to detect a relatively low frequency. The electrocardiac detector includes electrodes to detect potentials associated with heart beats, and is provided on each of the first and second detectors. The control unit converts electrocardiac signals detected by the electrocardiac detector into radio signals that are transmitted to the external unit. The external unit is a portable terminal apparatus, and includes a display unit formed by a liquid crystal panel on a front surface thereof, an operation part including operation buttons and ten-key, and patient selection buttons to select reading of data of patients.
