Abstract
The invention discloses a device and a method for acquiring heart sound. The device comprises auscultation clothes and four auscultation heads fixed on the auscultation clothes, wherein the auscultation clothes comprise a first elastic band, elastic lining cloth, a second elastic band and a fixed piece; the four auscultation heads comprise a first auscultation head, a second auscultation head, a third auscultation head and a fourth auscultation head respectively; the first auscultation head and the second auscultation head are fixed on the first elastic band; and the third auscultation head and the fourth auscultation head are fixed on the second elastic band. When the device for acquiring the heart sound is used for acquiring a heart sound signal, the auscultation heads can be directly fixed in the precordial region of a patient, and a doctor is not required to auscultate by handholding the auscultation heads, so that interference in auscultation caused by factors such as hand trembling of the doctor, body wobbling of the patient and the like can be prevented to acquire relatively pure heart sound signals, and the hear sound signals at four clinical auscultation positions can be synchronously acquired to provide more abundant clinical information.
Description
Technical field
The application relates to the armarium technical field, particularly relates to a kind of hear sounds harvester and method.
Background technology
Show according to " Chinese cardiovascular diseases's report (2008～2009) ": China cardiovascular diseases (coronary heart disease, apoplexy, heart failure, hypertension) morbidity and mortality rate all are growing trend, estimate that China cardiovascular diseases now suffers from number at least 2.3 hundred million, become " the No.1 killer " of Chinese's health.Along with the development of the globalization of mankind nowadays society, urbanization and aging, the cardiovascular disease problem becomes increasingly conspicuous.Therefore, how to find the sign of cardiovascular disease pathological changes as early as possible, in time understand its state of development, the prevention of cardiovascular disease and diagnosis and treatment are in time had great importance.
Hear sounds is the diastole contraction owing to valvular switch, tendon and muscle, the impact of blood flow and a kind of compound tone that the cardiovascular wall vibrations produces.The a large amount of pathological informations about heart various piece such as atrium, ventricle, trunk, cardiovascular and each valvular function state that it comprises are basic parameters of clinical assessment heart function state.When cardiovascular disease do not develop into as yet be enough to produce clinical and pathological change (changing) as electrocardiogram before, noise that occurs in the hear sounds and distortion are exactly important diagnostic information.Therefore, hear sounds has the irreplaceable important clinical diagnosis of electrocardio advantage.Simultaneously, easy to detect, noinvasive, the cost of cardiechema signals are minimum, can be used as that the cardiovascular diseases detects, the conventional means of prevention.
When clinically heart being carried out auscultation at present, the doctor needs hand-held stethoscope to move around at the auscultation position to determine the strongest position of sound and conduction orientation thereof usually.Because the cardiac auscultation effect is subjected to directly influencing of stethoscope sensitivity, people's ear audition state, doctor's clinical experience and auscultation technology, even if skilled doctor also needs by changing the stethoscopic position of contact on one side, carrying out auscultation repeatedly at the strongest position of sound comes the identification hear sounds on one side, and this often is difficult to the written in water sound detection that produces in the cardiomotility process is arrived.In addition, long-time auscultation also causes audition fatigue easily, and the hand-held auscultation head of doctor carries out auscultation, also the interference that can bring auscultation owing to factors such as the shake of doctor's hands and patient body rock.
Summary of the invention
In view of this, the embodiment of the present application provides a kind of hear sounds harvester and method, this hear sounds harvester is when gathering cardiechema signals, can be fixed on one's body the patient, and four auscultation heads that are provided with on it can the synchronous acquisition cardiechema signals, adopts hand-held stethoscope and singly leads the problem that bring tin clinic to solve.
To achieve these goals, the technical scheme that provides of the embodiment of the present application is as follows:
A kind of hear sounds harvester comprises: auscultation clothes and be fixed on four auscultation heads on the described auscultation clothes, wherein:
