Description
Technical field
The utility model is related to the embedded integral type implantation of a kind of pacemaker more particularly to a kind of wireless charging function
Pacemaker.
Background technology
The World Health Organization counts, and there are about 17,500,000 people to die of heart disease every year in the whole world at present.Bradycardia, the rhythm of the heart lose
Often, heart failure leads to death.Pacemaker has become treatment cardiovascular disease, such as the stopping of sinus property, sino atrial block, the atrium/heart
There is the important means of the diseases such as ectopic rhythm and tachycardia in room.Artificial cardiac pacemaker generally can be divided into external interim type and
Two kinds of embedded type, the former is mainly used for providing first aid temporary cardiac pacing, and the latter mainly supplies being chronically implanted property pacing therapy.It plants
Enter type pacemaker be it is a kind of being implanted in internal electronic therapeutic instrument, by impulse generator, battery, catheter electrode three parts
Composition, operation principle are：Battery provides energy to impulse generator；Impulse generator generates electric pulse, passes through lead electrode
Conduction, the cardiac muscle that stimulating electrode is contacted, make heart excitement and shrink, to reach treatment due to certain arrhythmia caused
Heart dysfunction purpose.
Since First pacemaker in 1958 is implanted into human body, pacemaker manufacturing technology and technique are fast-developing, work(
It can be gradually improved.Currently, at least 5,000,000 people sustain life by Implanted cardiac pacemaker treatment in the world, and this
Data are every year all in the speed increase by about 15%.Patient's pacemaker that the U.S. has 30 to 40 ten thousand heartbeats too slow every year, and
China needs the patient of pacemaker and this number almost the same, but actual installation person only has 1.5 ten thousand to 2 ten thousand people left
The right side is no more than the 1/5 of India；US and European is respectively 800 and 600 left sides per a population of one million cardiac Pacemaker implantation amount
The right side, and Chinese pacemaker implantation amount is only per a population of one million 20 or so at present.The implantation of China's pacemaker at present
Rate is low, and has 100,000 or more the newly-increased patients for needing implantable heart pacer, with the arrival of aging society, cardiovascular disease every year
Disease has the tendency that sharply increasing, and therefore, demand of the following China to heart heartstart is huge.
Currently, heart heartstart mostly uses disposable lithium-iodine battery both at home and abroad, energy supplement cannot be carried out after implantation.
When the electricity of battery consumption about 85% (typically about 5~7 years), it cannot ensure the normal work of pacemaker, it is necessary to and
Shi Genghuan is implanted into new pacemaker again.This not only increases new physiology pain, operation risk and financial burden to patient,
And constrain the use value of Implanted cardiac pacemaker.In particular, patient is to pacemaker, when electricity exhausts not
It holds, or even needs periodically hospital to be gone to be checked in before service life 1~2 year, this can undoubtedly cause some old ages
The inconvenience of patient.Therefore, there is an urgent need to the new technologies without using battery or external wireless power, so that all kinds of pacemakers are true
It is positive to realize " primary implantation uses all the life ", exempt patient and operates on the trouble and worry for replacing implantation again.
It realizes wireless charging, has three ways, such as microwave, electromagnetic induction and magnetic coupling resonance.Microwave mode can realize high power
And remote transmission, but directionality is poor, is unable to cut-through object, and big, easily fever is lost.Electromagnetic induction method, passing can principle class
Be similar to transformer, realize it is simple, the disadvantage is that transmission range is short, mostly mm grades (generally within 2cm), and it is generally desirable to coils just
Right, i.e., transmitting and receiving coil only have to be bonded completely substantially could transmit energy, and therefore, common mode is by charging equipment
It is placed on one " tablet ", typical products are charging pad.The common mobile phone of exhibition and electric toothbrush wireless charging mostly use electricity
Magnetic inductive.The third be magnet coupled resonant type wireless pass can technology, transmission range relatively far away from, efficiency it is relatively high, to people
Body is substantially harmless.The technology is newer, in 2007 by propositions such as Massachusetts Institute Technology M.Soljacic, utilizes the technology point
60 watts of light bulbs outside bright two meters, and set up WiTricity companies.
In recent years, carrying out wireless charging to pacemaker using electromagnetic induction and magnetic coupling resonance manner has some reports.
Such as：Chinese invention patent《Power adjustable formula wireless charging device applied to Implanted cardiac pacemaker》(application number
CN201410004449.5, date of application 2014.01.06) disclose it is a kind of using electromagnetic induction to Implanted cardiac pacemaker
The method for carrying out wireless charging, wherein in transmitting terminal using three-dimensional round table-like transmission spiral coil and bowl-type power regulation list
Member adjusts the transmission power of transmitting coil, to solve radio energy-transmitting efficiency caused by electromagnetic energy power excessively dissipates too low
The problem of even failing.Chinese invention patent《A kind of implantable cardiac artificial or electronic heart pacemaker magnetic coupling resonance wireless charging device》(application
Number CN201310493063.0, date of application 2013.10.18) and《The wireless charging method of pacemaker based on magnetic resonance
And device》(number of patent application CN201410025298.1, date of application 2014.01.20) is proposed using magnetic coupling resonance
The method that mode carries out wireless power to pacemaker.
Due to the lithium-iodine battery and impulse generator of pacemaker, it is both placed in sky closed made of titanium alloy welding
Between in because metal can stop magnetic field, the wireless charging method used at present is obtained in the receiving terminal of wireless charging
After energy, then connect by conducting wire, charged the battery, i.e. wireless charging with the rechargeable battery in pacemaker
Receiving terminal be located in except pacemaker.Two problems can be brought in this way：When the receiving terminal of wireless charging with rise
Fight and need circuit connecting wire between device, there are connecting lines to fall off, be broken or circuit connection that aging etc. is brought whether reliable wind
Danger；Second is that the component to implant is other than pacemaker, and has increased the receiving terminal of wireless charging newly, in this way, increasing in vivo
The risk infected by the surface of a wound and patient.
