Referring to fig. 1 to 2, the implant filling of the present invention is a first embodiment as follows:
Implant filler is applied to a body implant 100, and a closed cavity 110 is provided inside the implant 100.
The implant filling comprises a coil 200, a magnetic field generator 300, a magnetic field sensor 400.
The coil 200 is disposed in the closed cavity 110 of the implant 100, with the bottom of the coil 200 broken, abutting the bottom of the coil 200 against the bottom wall of the closed cavity 110.
The magnetic field generator 300 is used to apply a magnetic field to the implant 100, and the magnetic flux of the coil 200 is changed by turning off the magnetic field generator 300, so that the coil 200 generates an induced current and maintains the induced current for a period of time.
The magnetic field sensor 400 is used to detect an induced magnetic field generated by the coil 200 due to the flow of an induced current.
The magnetic field generator 300 is activated to apply a magnetic field to the implant 100, and then the magnetic field generator is turned off and the magnetic field sensor 400 is activated to detect the induced magnetic field of the coil 200 due to the induced current.
Since the coil 200 is disposed in the closed cavity 110 of the implant 100 and the bottom of the coil 200 is broken to be in contact with the bottom wall of the closed cavity 110, when leakage occurs in the implant 100, a liquid flows into the closed cavity 110 of the implant 100, and the liquid serves as a conductor to form a closed loop of the coil 200.
After the magnetic field generator 300 is applied to the implant 100, the magnetic field generator 300 is turned off, and the magnetic flux of the coil 200 is reduced to zero, so that an induced current is generated and maintained for a certain period of time.
Then, the magnetic field generator 300 is turned off, and the magnetic field sensor 400 detects the induced magnetic field generated by the coil 200 due to the induced current flow, so that it can be determined that the closed cavity 110 of the implant 100 is leaky.
The method does not need to judge whether the implant 100 leaks or not by observing whether the symptoms such as inflammation, atrophy, damage and the like appear in tissues around the implant 100, timely detects the micro-seepage condition of the closed cavity 110 in the implant 100, achieves early detection and early treatment, avoids the symptoms such as bacterial infection, inflammatory reaction, failure of the implant 100 and the like, and reduces the need of subsequent complex treatment, thereby reducing the economic burden of patients, simultaneously reducing the discomfort and pain of the patients and improving the satisfaction degree of the patients.
In some embodiments, the implant filling is further provided with a water absorbing member 700, the water absorbing member 700 being provided at the bottom of the coil 200, the water absorbing member 700 abutting against the bottom wall of the closed cavity 110. The water absorbing member 700 is in an insulated state when not absorbing water, so that the bottom of the coil 200 is kept open. After the water absorbing member 700 absorbs the liquid, a large amount of conductive ions exist in the liquid, so that the bottom of the coil 200 is conducted, and the coil 200 forms a closed loop.
By the absorbent member 700 absorbing the liquid leaking into the closed cavity 110 of the implant 100, even if the total amount of liquid is insufficient to completely wet the entire absorbent member 700, the liquid may deteriorate the insulation performance of the absorbent member 700, and even a small amount of leaking liquid may cause the bottom of the coil 200 to be conducted, thereby improving the accuracy of the leak detection of the implant 100.
In some embodiments, the water absorbing member 700 is coated or doped with an electrolyte.
When the liquid leaking into the closed cavity 110 of the implant 100 adheres to the water absorbing member 700, the electrolyte on the water absorbing member 700 is dissolved to release a large amount of conductive ions, so that the insulating property of the water absorbing member 700 is further reduced, the conductivity of the water absorbing member 700 is improved, the charging efficiency and the discharging efficiency of the coil 200 are improved, the coil 200 is facilitated to generate a stronger magnetic field, and the magnetic field sensor 400 can more accurately measure the induction magnetic field generated by the coil 200.
In some embodiments, the implant filler is also provided with an insulated wire 800, the insulated wire 800 connecting the open position of the bottom of the coil 200.
The insulation wire 800 is connected to the off position of the bottom of the coil 200, and the off position of the bottom of the coil 200 is turned on after the liquid leaked to the closed cavity 110 submerges both ends of the entire insulation wire 800.

The water absorbing member 700 is in an insulated state when not absorbing water, so that the bottom of the coil 200 is kept open. After the water absorbing member 700 absorbs the liquid, a large amount of conductive ions exist in the liquid, so that the bottom of the coil 200 is conducted, and the coil 200 forms a closed loop.
By the absorbent member 700 absorbing the liquid leaking into the closed cavity 110 of the implant 100, even if the total amount of liquid is insufficient to completely wet the entire absorbent member 700, the liquid may deteriorate the insulation performance of the absorbent member 700, and even a small amount of leaking liquid may cause the bottom of the coil 200 to be conducted, thereby improving the accuracy of the leak detection of the implant 100.
In some embodiments, the water absorbing member 700 is coated or doped with an electrolyte.
When the liquid leaking into the closed cavity 110 of the implant 100 adheres to the water absorbing member 700, the electrolyte on the water absorbing member 700 is dissolved to release a large amount of conductive ions, so that the insulating property of the water absorbing member 700 is further reduced, the conductive capacity of the water absorbing member 700 is improved, the induced current generated by the coil 200 is improved, and the coil 200 is facilitated to provide sufficient current for the signal emitter 500 to ensure that the signal emitter 500 continuously emits signals.
