Abstract
A heart pulsating aid for curing cardiac disfunction is composed of heart sound sensor, signal processing circuit and vibration wave output device. Said heart sound sensor's input is directly put on heart acupoint of human body and its output is connected to the input of signal processing circuit whose output is connected to the input of vibration wave output device which is a device converting electronic signal into mechanical vibration wave. The output of said output device is aimed at the position of body to receive vibration wave. Its advantages include no by-effect, simple structure, low cost, high curative effect, and high safety.
Description
The invention belongs to a kind of medical apparatus and instruments, particularly a kind ofly treat the cardiac pacemaker that cardiac insufficiency that a variety of causes causes must be strengthened cardiac contractile force.
At present, the heart failure that some heart disease such as rheumatic heart disease, congenital heart disease etc. cause (satisfactory again functional defect), long-term torment patient, the doctor uses various ways, as cardiac tonic (Cardiokinetie), diuresis, improve blood circulation, operation etc., therefore but unavoidably still have patient quite a lot to get killed; The myocardial ischemia of coronary heart disease (Myocardial Ischemic), long-term masty cardiac function weaken gradually, also can make the patient die from paroxysmal heart failure, and the concurrent in seconds especially acute heart failure of acute myocardial infarction (Acute myocardial Inlreti) and not controlling.The various countries scholar racks one's brains for this reason and avoids the negative effect that inotropic agent brings for heart in imminent danger from number of ways in recent years, but all absurd machine that takes a lot of trouble, then has to and rely on inotropic agent such as Folium Digitalis Purpureae class medicine solves heart failure for the moment.So-called inotropic agent is a cardiac tonic, the basic harm of treatment heart failure is it more is that depleted cardiac muscle more lacks oxygen, it is to strengthen pollex and oxygen consumed tolerance that the contractility that removes to strengthen heart with medicine then increases heart more, thereby make heart damage more serious, in the face of this vicious cycle, doctors understand already, load before and after reducing from other approach by fair means or foul, but still can not fundamentally solve the problem that improves the heart collecting moving ability.
The object of the present invention is to provide a kind of cardiac pacemaker, it is with self heart collecting moving power extraction, come to be added on patient's the heart through amplification and the relevant feedback of handling again, the pollex power of strengthening heart with resonating is alleviated the hour of danger of the depleted of heart or rescue acute heart failure then.
Technical scheme of the present invention: a kind of cardiac pacemaker, it is characterized in that it is made of heart sound transducer, signal processing circuit and the ripple output device that shakes, said heart sound transducer comprises pick up and pre-amplification circuit, the input of pick up directly places on the human heart acupuncture point, the input of its output termination pre-amplification circuit, the outfan of pre-amplification circuit is connected with the input of signal processing circuit; Said signal processing circuit comprises signal filtering and amplifying circuit and signal shaping and drive circuit, the input of signal filter circuit connects the outfan of heart sound transducer, the input of its output termination amplifying circuit, the input of the output termination signal transformation circuit of amplifying circuit, the shake input of ripple output device of the input of the output termination drive circuit of signal transformation circuit, the output termination of drive circuit; The said ripple output device that shakes is one to change electronic signal the device of mechanical vibration wave into, and its input is connected with the outfan of signal processing circuit, and the outfan of the ripple output device that shakes is aimed at human body and received the ripple position that shakes.
The above-mentioned said ripple output device that shakes can be made of relay, spring, armature contact plate and supporting plate, relay and spring hang down separately from being installed on the supporting plate, the bracket end of armature contact plate one end and supporting plate is hinge joint, but its tip side and relay are the opening and closing moving type, spring places between relay and the support and the static shape of spring is higher than relay adhesive place height, the input of relay is connected with the outfan of signal processing circuit, and the tip side of armature contact plate is aimed at human body and received the ripple position that shakes.
Operation principle of the present invention and work process: at first human heart pulsatile heart tone signal is taken out and become the signal of telecommunication and amplify simultaneously by pick up, in the entering signal treatment circuit this cardiechema signals carried out filtering (being filtering harmonic wave and various clutter) afterwards, again its purified hear sounds peak signal is further amplified, shaping, make its become one identical with the cardiechema signals frequency, phase place has the square-wave pulse signal of certain hysteresis, this square-wave pulse is exported to the actuator ripple output device that promptly shakes, make relay in the ripple output device that shakes be with square-wave pulse in height, it is logical that the identical rule of low level changes, off-position, cause the tip side of armature contact plate also to be corresponding adhesive and to disconnect shape, compression spring during the contact board adhesive, spring force acts on contact board during disconnection, and so forth, electric impulse signal i.e. not disconnecting by the armature contact plate, close and change mechanical vibration wave into and act on the human heart acupuncture point, so promptly receive the effect of a mechanical vibration wave identical with the hear sounds frequency by human heart, thereby strengthened beating of heart, reached the power-assist purpose.
Superiority of the present invention and technique effect are: 1, be skillfully constructed, introduce electronic equipment treatment cardiac insufficiency initiatively, many side effect of pharmacotherapy have been avoided with physiotherapy completely, to reach redemption as much as possible causes dead people's life because of heart failure purpose; 2, simple in structure, cost is low, the patient is easy to accept; 3, be a kind of medical apparatus and instruments of atraumatic, thus safe in utilization, convenient, the obvious effective rate height, the tremulous pulse pollex power of the scratching index of actual measurement subject person, the per minute kind increases progressively 1.53%.
Further specify present technique below in conjunction with accompanying drawing and embodiment.
