Abstract

The invention discloses an electrode with intrakardial pace-making device, which comprises an electric conduction wire, wherein the front part of the electric conduction wire is connected with an electric conduction head; the electric conduction head is a memory alloy spring wire which is manufactured by using memory alloy microfilament and has a diameter less than or equal to 0.2mm. The invention can be used for rapidly, efficiently and safely rescuing patients in an emergency room, can improve rescue mission success rate of heart arrest patients, and obviously improve prognosis dispose and survival quality of a patient.

Description

The electrode that pacemaker is used in the heart

Technical field

The present invention relates to the electrode of the interior pacemaker of pacemaker, especially heart in a kind of heart.

Background technology

In the first aid rescue work of hospital, the patient of a large amount of sudden cardiac death of can seeing and treating patients, cardiopulmonary all standing and serious bradyarrhythmia to this class patient, mainly implements cardiac pacing with pacemaker in the heart.And the performance of pacemaker in the heart is played very important effect as the structure of the critical elements electrode of pacemaker in the heart.The electrode that uses only is a conduction steel wire at present, the front end of steel wire be provided with revolve curved, operational approach is, elder generation is cardiac compression to patient's closed cardiac massage or after opening breast, after treating that heart has electrical activity or hemodynamic stable, again under the X line through the vein otch with puncture needle iontophoresis electrode temporary cardiac pacing to the chambers of the heart, in the hope of controlling conditions of patients to greatest extent, recover hemodynamic stability, withdraw from electrode.The deficiency of this vein formula electrode is: venipuncture needs 10 minutes time, the surgical condition harshness, the surgery cost height, and also the emergency department of existing hospital generally all establishes X-ray equipment, the patient is not suitable for moving or transferring to x ray room again and carries out first aid, thereby influences therapeutic time and effect.And the steel wire matter of electrode is hard, and revolving of front end bent easy scratch cardiac muscle when withdrawing from.

Summary of the invention

The electrode that the purpose of this invention is to provide pacemaker in a kind of heart, use kind electrode without venipuncture, need not dispose X line equipment, pacemaker carries out cardiac pacing to the patient in emergency department just can be with heart, and not scratch cardiac muscle when withdrawing from.

For achieving the above object, the technical scheme that the present invention takes is;

It comprises one section conduction steel wire, it is characterized in that, the front end of conduction steel wire is connected with conductive head, and described conductive head is a joint memory alloy spring silk, and the memory alloy spring silk is the diameter that processed by the memorial alloy microfilament spring wire smaller or equal to 0.2mm.

For operator are played a protective role, on the conduction steel wire, scribble insulating barrier.

Using method is, at first on entire electrode, be coated with and spread medical silicone oil or hydrophilic coating, memory alloy spring is penetrated the cardiac puncture pin, memory alloy spring is exposed, pinch plane ring-type, be retracted into again in the pin chamber, get and take back under patient's xiphoid-process or outer two centimeters of left border of sternum the 4th intercostal are point of puncture perpendicular to conductive filament, the cardiac puncture pin is punctured in the ventricular chamber to the right, inserting needle, and meanwhile pace-making; After the heart puncture needle thrusts cardiac muscle, when finding premature ventricular beat (chamber early) or pace-making sample EGC change phenomenon, again inserting needle a little in ventricle, when finding that then blood flow in the puncture needle phenomenon, before push away electrode again and arrive endocardium for two centimetres, then the cardiac puncture pin is withdrawed from, at this moment, the memory alloy spring silk recovers the plane ring-type, electrode tail end and pacemaker is electrically connected the pace-making of can switching on.

The present invention has following characteristics:

1, technology is simple and convenient, need not to carry out the vein otch at the skin place, has reduced patient's misery, simultaneously the operator is required lowly, generally after practice 5 example operations, promptly can operate separately.

When 2, implanting pacing electrode, conductive head is in the puncture needle cavity, avoids myocardial damage and hemorrhage, has lowered damage coronary artery and venous probability, and can reduce the probability of clean steel silk electrode fracture.

3, after conductive head is implanted heart, be rich in extremely strong elasticity, can move with heartbeat, not the easy damaged endocardium.

4, when taking out electrode, conductive head is straightened easily, is difficult for causing myocardial damage.

5, because conductive head is the plane ring-type, increase with the endocardium contact area, so the pace-making better effects if.

6, because handle section scribbles insulating barrier, operator are played the electrical shock protection effect.

In a word, the present invention can emergency room fast, efficient, safe carry out rescue patient, improved the salvage success rate of sudden cardiac arrest patient, obviously improve patient's pre-post processing and life quality.

Among the figure: 1-conductive head, 2-conduct electricity steel wire, the 3-insulating barrier.

The specific embodiment

As shown in Figure 1, the present invention includes one section conduction steel wire 2, the front end of conduction steel wire 2 is connected with conductive head 1, and described conductive head 1 is a joint memory alloy spring silk, and the memory alloy spring silk is the diameter that processed by the memorial alloy microfilament spring wire smaller or equal to 0.2mm.

For operator are played a protective role, on conduction steel wire 2, scribble insulating barrier 3.

Using method is, at first on entire electrode, be coated with and spread medical silicone oil or hydrophilic coating, memory alloy spring is penetrated the cardiac puncture pin, memory alloy spring is exposed, pinch plane ring-type (as shown in Figure 3), be retracted into again (as shown in Figure 2) in the pin chamber, get and take back under patient's xiphoid-process or outer two centimeters of left border of sternum the 4th intercostal are point of puncture perpendicular to conduction steel wire 2, the cardiac puncture pin is punctured in the ventricular chamber to the right, inserting needle, and meanwhile pace-making; After the heart puncture needle thrusts cardiac muscle, when finding premature ventricular beat (chamber early) or pace-making sample EGC change phenomenon, again inserting needle a little in ventricle, when finding that then blood flow in the puncture needle phenomenon, before push away electrode again and arrive endocardium for two centimetres, then the cardiac puncture pin is withdrawed from, at this moment, the memory alloy spring silk recovers plane ring-type as shown in Figure 3, electrode tail end and pacemaker is electrically connected the pace-making of can switching on.
