A kind of Implanted cardiac pacemaker is provided with circuit board main body 22, circuit board main body 22 on pacemaker circuits plate 11
It is fixedly connected on the front end outer wall of internal battery 10 by bonding agent, circuit board main body is connected with control at 22 front end outer wall center
Coremaking piece 23, controls and is connected with perception chip 21 on the 22 front end outer wall of circuit board main body in 23 left side of chip, and control chip 23 is right
Pulse pio chip 24 is connected on the 22 front end outer wall of circuit board main body of side, control chip 23, perception chip 21 and pulse are defeated
Chip 24 keeps electric connection state between each other out, controls the effect of chip 23 are as follows: when is sent out according to control model decision
Pacemaker impulse is sent, or whether needs to change control model, and whether needs to save data, and timer when its core component,
When the accurate timing generated by clock pulses, the control decision of chip 23 trigger pacemaker impulse, determine blanking and refractory period
Interphase determines chamber delay and whether reset timer since cardiac muscle is in refractory period detects that is issued after R wave immediately rises
Pulse of fighting will not generate any effect to cardiac muscle, so as to avoid the stimulation in the vulnerable period of cardiac muscle by electric pulse, and arteries and veins
Rushing pio chip 24 then is the final circuit for generating Cardiomyocytes and issuing voltage pulse, it acts as: the electric pulse of appropriate intensity can
The action potential that can be issued with stimulating cardiac muscle to generate, eventually leads to myocardial contraction and heartbeat, principle is then by electricity
Capacity charge store electric energy, when pacemaker circuits plate 11 determine provide pulse when, capacitor electric discharge, thus reach help myocardial contraction and
The purpose of heartbeat, impulse generator 7 is equal with the transverse width of internal battery 10, impulse generator 7 and internal battery 10
The distance between and impulse generator 7 and the distance between internal battery 10 and 1 inner wall of pacemaker shell be equal, pulse hair
There are two buffer bracing means 8, impulse generator 7 and 1 inner wall of pacemaker shell for raw device 7 and the opposite intermediate connection of internal battery 10
Between six buffering bracing means 8,14 bufferings are connected separately between 1 inner wall of internal battery 10 and pacemaker shell
The shape size and structure composition of bracing means 8 are all the same, buffer bracing means 8 on buffer bar 19 inside surge chamber 14 most
Big operating range is that distance obtains half between impulse generator 7 and internal battery 10, and 14 buffer protection devices can
Multi-orientation multi-angle inside pacemaker shell 1 to impulse generator 7 and internal battery 10 is fixed and buffer function, from
And reach to impulse generator 7 and internal battery 10 reinforce be fixed to 1 inside of pacemaker shell while it is also possible that
Entire Implanted cardiac pacemaker has certain impact resistance, so that entire Implanted cardiac pacemaker is using
Carry out more highly effective and safe, the length and width of pacemaker circuits plate 11 is respectively less than the length and width of internal battery 10, pacemaker
The thickness of circuit board main body 22 on circuit board 11 is only one millimeter, enables to pacemaker circuits plate 11 in being installed in this way
After setting on the front end outer wall of battery 10, the overall thickness of assembled internal battery 10 and pacemaker circuits plate 11 does not interfere with it
It is normally installed to inside pacemaker shell 1, is used so as to guarantee that pacemaker can be normally carried out assembling.
The working principle of the invention and process for using: after the present invention installs, when in use firstly the need of pacemaker
Circuit board 11 is installed on the front end outer wall of internal battery 10 by bonding agent, and both to be electrically connected, then again
Impulse generator 7 is installed to inside 1 lower semisection of pacemaker shell by six buffering bracing means 8, then in mounted arteries and veins
It rushes 7 upper end of generator to draw internal battery 10 by two buffering bracing means 8 and be connected to the upper end, and needs are internal battery 10
Reinforcing fixation is carried out inside pacemaker shell 1 by other six bufferings bracing means 8, and finally pacemaker shell 1 is carried out
Encapsulation, two connection jacks 4 then one end of anode pipe 2 and cathode conduit 3 being each individually connected to respectively on link block 5
Inside, finally carried out again by performing the operation entire Implanted cardiac pacemaker to be installed on the body of user using and pacing
The function of perception chip 21 on device circuit board 11 is realized, time window: according to cardiac cycle, is being detected R wave or is being issued
R wave or P wave can not be had by fighting in postimpulse a period of time, make the letter in electrode in perception chip 21 by blanking circuit
It is not passed to amplifier number not, blanking time 10-400ms, as refractory period, and by setting refractory period, pacemaker can be prevented
Other extraneous signal false triggerings are involved by T, and cause that pacing frequency slows down or paced rate is uneven, and control the effect of chip 23
Are as follows: when pacemaker impulse is sent according to control model decision, or whether needs to change control model, and whether need to save number
According to, and when timer when its core component, the accurate timing generated by clock pulses, the control decision of chip 23 trigger pace-making
Pulse, determine blanking and refractory period interphase, determine chamber delay and whether reset timer, due to cardiac muscle be in refractory period,
Detect that the pacemaker impulse issued immediately after R wave will not generate any effect to cardiac muscle, so as to avoid the rapid wear in cardiac muscle
Stimulation of the phase by electric pulse, and frequency adaptation pace-making is in addition to needing to detect cardiac electrical activity, it is also necessary to detect blood pressure, blood
Oxygen, body temperature, metabolic water equality index automatically determine pacemaker impulse on the basis of comprehensively considering Human Physiology actual needs
Frequency is sent, is a kind of closer to ideal control model, on the basis of these basic models, according to detection position, stimulation
The difference at position etc., develops many practical pacemaker types and mode, and pulse pio chip 24 be then finally generate to
Cardiac muscle issues the circuit of voltage pulse, it acts as: the electric pulse of appropriate intensity can stimulate cardiac muscle to generate the movement that can be issued
Current potential, eventually leads to myocardial contraction and heartbeat, and principle is then to work as pacemaker circuits by storing electric energy to capacitor charging
When plate 11 determines to provide pulse, capacitor electric discharge, to achieve the purpose that help myocardial contraction and heartbeat.
