Description

A kind of wearable cardiopulmonary intestinal overall checkout equipment and detection method
Technical field
The present invention relates to a kind of wearable cardiopulmonary intestinal overall checkout equipment and detection method.
Background technology
Analysis of PCG Signal is a kind of basic skills of assess cardiac function state.One of clinical manifestation that rheumatic heart disease is main is exactly that corresponding cardiac murmur appears in the valve area of pathological changes.Therefore the hear sounds diagnosis is the cardiopathic a kind of very effective and basic means of diagnosticating rheumatic.Intestinal is pipeline the longest in digestive organs, once intestinal has extremely, just has and can cause Disorder of Digestion and Absorption, and a series of related symptoms.The frequency when frequency of borborygmus under normal circumstances and intestinal abnormal is different, and by the auscultation borborygmus, the doctor can judge patient's digestion situation.Therefore borborygmus is an important means of clinical diagnosis intestinal tract disease.Contain a large amount of information in lungs sound, human lung's various diseases is all not yet grasped reflection to some extent in the lungs sound of its rule at us.Noinvasive based on auscultation of lung, low cost and other advantages, lungs sound also becomes a basic means that detects pulmonary disease.
The diagnosis of the current heart, lung, intestinal is all used separately relevant device to be detected, and precision is not high yet.If the cardiopulmonary intestinal all will detect, frequently more exchange device certainly will bother very much.In addition, these detections are all to carry out in hospital, and the patient must be in hospital's wait for a long time, and most equipment can not carry out continuous monitoring and can not position abnormal sound, thereby can not provide comprehensive data to the doctor.
Nowadays the sound localization algorithm is day by day ripe, can the three-dimensional localization sound source, and accurate localization of sound source, the existing flight-line maintenance industry that is applied to, in not extensively utilization of medical industry more.
Summary of the invention
The defect that the present invention seeks to exist for prior art provide a kind of can continuous monitoring and cardiopulmonary intestinal overall checkout equipment and the detection method of localization of sound source.
The present invention for achieving the above object, adopt following technical scheme: a kind of wearable cardiopulmonary intestinal overall checkout equipment, comprise that inner surface posts the clothes of some sound transducers and signal processing system, data storage, wireless module, power module and terminal presentation facility, also be provided with the slack adjuster of being convenient to sound transducer aim detecting position on described clothes, described sound transducer all is connected with signal processing system.

Preferably, described signal processing system comprises signal amplifier, wave filter, digital to analog converter, sound localization computing module, heart and lung sounds separation module;
Described signal amplifier for by each Sensor monitoring to acoustical signal amplified;
Described wave filter is for filtering the noise of acoustical signal;
Described digital to analog converter converts digital signal to for the intestinal acoustical signal that wave filter is filtered;
Described sound localization computing module is for locating the abnormal sound source of the heart, lung and intestinal;
Described heart and lung sounds separation module is for separating cardiechema signals with Lung Sounds.
Preferably, described wireless module is divided into:
Wireless transmitter, go out for the data transmission of the data by storage or Real-Time Monitoring;
Wireless receiver, be built on terminal presentation facility, is used for receiving above-mentioned data.
Preferably, described terminal presentation facility is the portable display device that comprises the mobile phone with Bluetooth function, for the particular location data of the sound waveform data that show each position of cardiopulmonary intestinal and abnormal sound source.
A kind of wearable cardiopulmonary intestinal method for comprehensive detection, its method is: sound transducer is arranged in to thoracic cavity and abdominal cavity, the hear sounds that sound transducer collects, lungs sound and borborygmus signal pass to signal processing system sound source are carried out to three-dimensional localization, finally the particular location data of the voice data at each position of cardiopulmonary intestinal of acquisition and abnormal sound source are passed to wireless signal receiver and terminal presentation facility by wireless signal transmitter.
Preferably, described sound transducer be arranged in respectively near cardiac position, apex pulmonis position, near the bronchus position, near the bronchioles position, middle part, caecum position, ascending colon middle part and the transverse colon middle part of lung bottom position, colon descendens middle part, Sigmoidocolic middle part, whole intestinal.
Beneficial effect of the present invention: a plurality of sound transducers are monitored heart, pulmonary and intestinal, can be comprehensively, the acoustical signal of continuous monitoring cardiopulmonary intestinal, data are comprehensive, and the sufferer position is positioned, thereby for the doctor provides more scientific diagnosis basis, the patient can break away from hospital simultaneously, does not affect orthobiosis.The sound transducer size that the present invention adopts is little, and precision is high, dresses this equipment and can not allow the patient do not feel like oneself.On clothes, slack adjuster can be regulated according to different crowd, strong adaptability.
The accompanying drawing explanation
Fig. 1 sound transducer schematic layout pattern;
Fig. 2 fundamental diagram of the present invention.
The specific embodiment
Figure 1 shows that the sound transducer schematic layout pattern.Sound transducer, used the piezoelectric effect principle, is manufactured with mass on sound transducer, and the mass upper and lower surface connects by cantilever beam, and the upper surface of cantilever beam has been done piezoelectric layer, and the structure of cantilever beam is asymmetric.141 for posting the clothes of sound transducer and 131 processing modules, on clothes, be manufactured with can adjusting elasticity device so that top sensor can be aimed at position to be monitored.It is three parts that sensor combinations is divided into: cardiac component, pulmonary's part and intestinal part, every part has been used a plurality of sensors.Wherein, 101 four sensors that are cardia, be evenly arranged in cardiac position.111 ~ 118 sound transducer groups that are pulmonary.Wherein, sensor 111 and 118 is arranged near the apex pulmonis position, and 112 and 117 are arranged near the bronchus position, and 113 and 116 are arranged near the bronchioles position, and 114 and 115 are arranged in the lung bottom position.Four sound transducers of every lung use can the comprehensive monitoring lung sounds.121 ~ 126 sensor groups that are the intestinal position.Wherein, sound transducer 121 is positioned over colon descendens middle part, and 122 are positioned over Sigmoidocolic middle part, and 123 are positioned over the middle part of whole intestinal, and 124 are positioned over the caecum position, and 125 are positioned over the ascending colon middle part, and 126 are positioned over the transverse colon middle part.Whole intestinal tract is monitored borborygmus with 6 above-mentioned sound transducers.The combination that 131 signal processing systems are date processing, data storage, wireless transmitter module and power supply.
