As shown in Fig. 4, the internal pacemaker includes a first antenna 1, and the external controller includes a second antenna (not labeled). The external controller 12 uses the second antenna to provide electric energy to the first antenna 1 through electromagnetic induction coupling. The first antenna 1 is used to supply power to the pacemaker 11 in the body. The present invention adopts a passive wireless power supply method to make the heart start The life of the pacemaker is no longer limited by the battery. The permanent pacemaker has a service life of more than 20 years, and due to the battery-free design, the weight of the whole machine is greatly reduced, and the patient feels better.

Specifically, the external controller 12 has the capability of wirelessly supplying power to and communicating with the internal cardiac pacemaker 11, and considering the attenuation of the electromagnetic field, its radio frequency range should be 2MHz-50MHz. Considering the electromagnetic compatibility and the power consumption of the pacemaker 11 in the body, the radio frequency power range should be 50mW˜1000mW.

In addition, considering radiation safety, anti-interference, patient comfort and other conditions, the shape of the first antenna 1 can adopt a circular, square or three-dimensional structure, and the equivalent cross-sectional area is estimated by the following engineering formula:

S≈H ² /(25*P)

Wherein S is the equivalent cross-sectional area of the first antenna 1 (unit is mm ² ), H is the distance between the first antenna 1 and the body surface (unit is mm), and P is the radio frequency power of the external controller 13 (unit is W) .

In order to enable the first antenna 1 to have a controllable degradation capability in the human body, the first antenna 4 is made of a magnesium-calcium alloy, and the complete degradation time is adjusted by controlling the ratio of the magnesium-calcium element in the alloy. The complete degradability time of the first antenna 1 is controlled within about 3 months, and the impedance of the first antenna 1 is controlled within the range of 50Ω±0.1Ω.

In order to protect the structure and circuit of the pacemaker 11 in the body from being corroded by the biological environment, a first biological protective film 2 is arranged outside the first antenna 1, and the first biological protective film 2 is made of polylactic acid glycolic acid, ethylene terephthalate Made of alcohol ester, polyester fiber or polyether ether ketone, it is non-toxic and harmless to organisms before and after degradation, has good flexibility and is comfortable for the human body. Specifically, when it is suitable for temporary cardiac pacemaker scenarios, polylactic acid glycolic acid materials are generally used, and the degradation time is controlled by controlling parameters such as the thickness of the protective film. The general thickness range is 10um to 1mm, and the complete degradation time is generally within 1 week. ~3 months. Ethylene terephthalate or polyester or polyether ether ketone materials are generally used when suitable for permanent pacemakers. The cardiac pacemaker provided by the present invention is easy to use, because the first biological protective film arranged outside the first antenna is replaceable, and can be replaced according to the service life requirements of the cardiac pacemaker, for example, when a permanent cardiac For pacemakers, you can choose the first bioprotective film made of ethylene terephthalate or polyester fiber or polyetheretherketone material. The first bioprotective film made of ethylene glycol diformate or polyester fiber or polyether ether ketone material is replaced by the first bioprotective film made of polylactic acid glycolic acid material, in other words, the first bioprotective film The membrane can be replaced at any time. During the operation, according to the age requirements of the cardiac pacemaker that the user needs to use, the first bioprotective membrane made of the corresponding material is directly selected and placed outside the first antenna.

In one example, the internal pacemaker 11 further includes an electrode 4, which is connected to the endocardium or the surface of the myocardium, forms an electrical circuit with the heart, and stimulates the myocardium to complete pacing. In different cardiac pacemakers, the material selection of electrode 4 is different. In temporary cardiac pacemakers, electrode 4 is made of degradable magnesium-calcium alloy materials. In permanent cardiac pacemakers, non-degradable Made of titanium alloy.

Only authenticated triggered cardiac pacing pulses are allowed.

In order to protect the pacing lead 5, a second biological protective film 8 is arranged outside the pacing lead 5, and the second biological protective film 8 is made of polylactic acid glycolic acid, ethylene terephthalate, polyester fiber or polyether ether Made with ketones. It should be pointed out that the material of the second biological protection film 8 is consistent with that of the first biological protection film 2 . At the same time, in order to make the pacemaker easy to use, like the first biological protective film, the second biological protective film is also replaceable, and it can be replaced according to the service life of the pacemaker, for example, when a permanent cardiac pacemaker is required When using a pacemaker, you can choose the second biological protection film made of ethylene terephthalate or polyester fiber or polyetheretherketone material. When you need to use a temporary pacemaker, you can directly use terephthalic acid The second biological protection film made of ethylene glycol ester or polyester fiber or polyetheretherketone material is replaced by the second biological protection film made of polylactic acid glycolic acid material. In other words, the second biological protective film can be replaced at any time. During the operation, according to the age of the pacemaker that the user needs to use, the second biological protective film made of the corresponding material is directly selected and placed on the pacing lead. outside.

The pacing wire 5 connects the electrode 4 and the main body of the cardiac pacemaker 11 in the body, and transmits pacing current and ECG monitoring signals. The choice of material for the pacing wire 5 needs to match the selection of the material for the electrode 4. In the application scenario of a temporary cardiac pacemaker, the material of the pacing wire should be made of magnesium-calcium alloy. In the application scenario of a permanent cardiac pacemaker, the pacing wire The wire material should be made of titanium alloy. Therefore, as a temporary cardiac pacemaker, patients can be discharged from the hospital after surgery without waiting for the pacing lead to be removed, and they can still receive health care for a certain period of time after discharge.

The alloy ratio of the pacing wire 4 is the same as that of the first antenna 1, but it should be composed of multiple thinner alloy wires, the number of strands is not less than 10 strands, and the total diameter is not greater than 1mm.

It can be seen from the above description that each part in the internal pacemaker of the present invention adopts degradable materials, therefore, the present invention has the ability to switch between temporary cardiac pacemaker and permanent cardiac pacemaker by replacing the biological protective film, pacing wire and electrodes Pacemaker capabilities.
