Abstract
The invention relates to a novel endocardial pacing or defibrillation device. A graphene material is utilized to manufacture an endocardial pacing electrode and a pacing lead, threshold rising caused by inflammatory response can be avoided, thrombosis risks caused by blood flush can be further reduced, external remote measurement charging is employed, so the volume of an internal device is greatly reduced, charging is convenient, and durability is improved.
Description
Technical field
Arrhythmia has very high sickness rate in the whole world, although some non-malignant arrhythmia can not rapidly result in extremely
Die, but the subjective feeling giving people brings a lot of discomforts, and the complication causing also causes very macrolesion to patient's body, such as atrial fibrillation
The thrombosis causing are the main sources of cerebral infarction；Some malignant arrhythmias then may rapidly cause hemodynamics disturbance, then
Lead to the generation of acute death incident.
Background technology
For the fast arrhythmia of Ventricular Rate, Therapeutic Method has Drug therapy, radio-frequency (RF) ablation and external defibrillation treatment.Wherein
Drug therapy guards safety the most, but onset is slow, and medicine adjustment needs individuation, and patient needs repeatedly periodically to nurse one's health to outpatient service,
For the bad patient of compliance, often due to medication is irregular leads to Drug therapy failure；Radio-frequency (RF) ablation is with electric current or cold
Accessory pathway is blocked by jelly method, it has been found that this method has two drawbacks in clinical position, one: conductive beam is
A kind of visually sightless signal transduction pathway, is clinically the position with experimental succession to determine conductive beam, therefore, right
In different cases, the blocking-up of conductive beam can not possibly all reach promising result；Two: the patient that left room is expanded, room wall is very thin,
Radio-frequency (RF) ablation easilys lead to atrium rupture, often wants emergency chest operation, very critical；External defibrillation treatment is usually to send out
The Therapeutic Method with certain injury from electricity that raw atrial fibrillation or room are carried out when quivering although effect is significant, but because defibrillator belongs to
Professional treatment equipment, Common People can not possibly conventional be equipped with, and tosses about in bed to often late during hospital.For the rhythm of the heart that Ventricular Rate is slow
Not normal, Therapeutic Method has Drug therapy and pacemaker treatment.Its drug treatment is similar with aforesaid content, and drawback is no longer superfluous
State；And pacemaker treatment is the most effective and most widely used Therapeutic Method of the slow arrhythmia of Ventricular Rate, it is divided into endocardium to rise
Fight and two kinds of Epicardial pacing.But from the point of view of from current clinical position, it there is a problem of being difficult to go beyond below: 1, endocardium rises
Fight and meet physiology mode of cardiac pacing, myocardial electrical signals are transmitted to visceral pericardium from endocardium, but installation difficulty, bleeding risk is big, it is desirable to have
The doctor of rich experiences operates, and surgery to be had is escorted；2, Epicardial pacing is easy for installation, but the sense of current and physiology pace-making side
To contrary, do not meet the unpolarized order of myocardium physiology；3, due to due to battery, pacemaker volume is larger, the life-span of battery
It is directly proportional to volume size, or patient faces huge foreign body in vivo, or facing the risk changing battery；4, adopted by pacemaker
With metal electrode film, heat loss is more, on the one hand increases the consumption of electricity, on the other hand causes inflammatory reaction around.
Content of the invention
It is proposed that a kind of new endocardial pacing or defibrillation device have the following characteristics that 1, endocardial pacing or remove
Quiver, meet electro physiology；2, Graphene electrodes piece, conduct electricity very well, heat production is little, the superthin structure of two dimension can be pasted by interventional method
Apply in sinuatrial node or other endocardium, blood flow will not be produced in endocardium installation and wash away, and pace-making, defibrillation effect are good；3, adopt
Wireless charging technology, the outer body of device produces magnetic field for electrified coil, and the route setting with device rotates, as long as patch
On thoracic wall, internal body portion produces electric current for conductor cutting magnetic induction line, and electric current exports three units, the electricity of a very little
Pool unit (due to can carry out remote sensing charging at any time, the battery volume of this device can greatly reduce), one is used for pace-making
Small capacitances, and a bulky capacitor being used for defibrillation；4, all of electrode part is all grapheme material or graphite ene coatings, makes electricity
Stream loss is preferably minimized；5, device outside can set every numerical value of pace-making, defibrillation, the signal of telecommunication of detection vivo devices, battery
Work etc..
Body is shown in Figure of description: note: accompanying drawing is only schematic diagram, is not actual proportions.Marginal data: icon 1-6 is device
Internal body portion, icon 7-10 be device outer body.1: Graphene electrodes；2: graphene wire；3: battery；4: pace-making is single
Unit；5: defibrillating unit；6: the internal coiler part receiving magnetic induction line generation electric current；7: external hot-wire coil produces magnetic induction line portion
Point；8: power line；9: display screen；10: operation button.
Operation principle illustrates: first pass through coil (icon 7) energising of the outer body to device for the power line (icon 8),
Hot-wire coil produces magnetic induction line, and outer body moves back and forth in certain direction simultaneously, makes magnetic strength wire-electrode cutting device internal body portion
Encapsulated coil (icon 6), produces the principle of electric current, apparatus body interior loop part (icon 6) according to closing conductor cutting magnetic induction line
Electric current will be produced, electricity is conveyed to battery compartment (icon 3) by graphene wire (icon 2) by electric current, and electric current can transmit simultaneously
Pacing unit (icon 4) to device and defibrillating unit (icon 5), by operation button (icon 10) and display screen (icon 9),
Set paced rate, pace intensity, perception, or defibrillation intensity, defibrillation frequency, synchronous or asynchronous defibrillation, after setting, pace
Unit (icon 4) can send the signal of telecommunication by graphene wire (icon 2) to Graphene electrodes (icon 1), is used for carrying out chamber
Order paces, or passes through graphene wire (icon 2) to Graphene electrodes (icon 1) transmission electricity by defibrillating unit (icon 5)
Signal, is used for carrying out ventricular defibrillation.
In the installation of Graphene electrodes, pacing electrode is installed near sinuatrial node and left ventricular apex portion, to reach chamber
The purpose of order pace-making.Defibrillation electrode is arranged on right ventricle surface and left room, to reach the purpose of ventricular defibrillation.Due to pacing and removing
Quivering is all separately to carry out, so the electrode slice of left room is just permissible with one.
