Implanted active medical equipment in organisms.
In the present embodiment, the shape of the charge coil is round.But the shape of the charge coil can be removed
Go the other shapes other than circle, the invention is not limited in this regard.
Four magneto sensors 12 are separately positioned on the inside and outside of the charge coil 11.Referring to Fig. 1, it is arranged on
The number of the magneto sensor of the inside of the charge coil 11 is 1.The installation position of this magneto sensor is the charging wire
The geometric center of the interior zone of circle.In the present embodiment, since the shape of the charge coil is round, the magneto sensor
It is arranged on the circle centre position of the interior zone.
Other than a magneto sensor of circle centre position, the other three magneto sensor along the charge coil 11 outside
Perimeter is evenly distributed.
The characteristics of magneto sensor 12, is that it is able to detect that the variation of the magnetic field intensity of ambient enviroment.The magnetosensitive
Element 12 can be：Any one in Hall element, mistor or magnetic field strength transducer.Due to being implanted to life
Implanted active medical equipment in object body has a metal shell, and metal object close to the magnetic field intensity that can lead to space
Variation, so, when metal shell of the magneto sensor 12 close to the implanted active medical equipment, magnetosensitive member
Part 12 is able to detect that this close.
If a magneto sensor 12 detects the close of the metal shell of the implanted active medical equipment, claiming should
Magneto sensor 12 is triggered.
Fig. 2A to Fig. 2 D is respectively illustrated in varied situations, the use state of the wireless charging positioning device.Referring to
Fig. 2A, under the scene, in four magneto sensors 12, a magneto sensor only on the inside of the charge coil is touched
Hair.At this point it is possible to judge in the external wireless charging positioning device and the implanted active medical to implant
Equipment precisely aligns.
Under the scene shown in Fig. 2 B, there are two be triggered in four magneto sensors 12.The two magneto sensors 12 are distinguished
Positioned at the inner and outer of the charge coil.At this point, it in the external wireless charging positioning device and implants
There is no precisely contrapositions for the implanted active medical equipment.
Under the scene shown in Fig. 2 C, a magneto sensor in four magneto sensors 12 on the outside of the charge coil
It is triggered.At this point, in the external wireless charging positioning device and the implanted active medical equipment to implant
Also it does not align precisely.
Under the scene shown in Fig. 2 D, any one in four magneto sensors 12 is not all triggered.At this point, in body
The outer wireless charging positioning device is precisely aligned also without with the implanted active medical equipment to implant.
Judge whether due to being combined using the multiple magneto sensors of inside and outside for being separately positioned on the charge coil
Contraposition, the accuracy of judgement degree and detection sensitivity of wireless charging positioning device provided in this embodiment are apparently higher than coil coupling
Induction mode.
The present embodiment sets magneto sensor respectively by the inside and outside of the charge coil in wireless charging positioning device,
The position of the metal shell of implanted active medical equipment to implant is detected, is realized to the implanted in implantation organism
Active medical instrument is accurately positioned.
Second embodiment
Present embodiments provide a kind of technical solution of wireless charging positioning device.In the technical scheme, it is described wireless
Charging positioning device includes：Charge coil and six magneto sensors.Also, two in six magneto sensors set
It puts in the inside of the charge coil, four additional is uniformly arranged on the outside of the charge coil.
Referring to Fig. 3, the charge coil 31 is still circular coil.The magneto sensor 32 includes：It is arranged on described fill
Magneto sensor inside electric coil 31 and the magneto sensor being arranged on outside the charge coil 31.It is arranged on the charging
The quantity of magneto sensor inside coil 31 is two, and the quantity for being arranged on the magneto sensor outside the charge coil 31 is four
It is a.
In the present embodiment, two magneto sensors only inside the charge coil 31 are triggered, and be in
In the case that magneto sensor outside the charge coil 31 is not triggered, it is possible to determine that determine in external wireless charging
Position device and the implanted active medical equipment accurate contraposition to implant.
Due to being either in the quantity of the magneto sensor inside and out the charge coil 31 compared with first embodiment
More, therefore, wireless charging positioning device provided in this embodiment is more suitable for the implanted active medical larger to volume and sets
It is standby to be positioned.
The present embodiment sets magneto sensor respectively by the inside and outside of the charge coil in wireless charging positioning device,
The position of the metal shell of implanted active medical equipment to implant is detected, is realized to the implanted in implantation organism
Active medical instrument is accurately positioned.
3rd embodiment
Present embodiments provide a kind of technical solution of wireless charging localization method.In the technical scheme, it is described wireless
Charging localization method includes：Detect whether the magneto sensor being arranged on inside and outside the charge coil is triggered；If setting
Magneto sensor in the inside of the charge coil is triggered, and the magneto sensor for being arranged on the outside of the charge coil is equal
It is not triggered, then current location is exactly the implantation position of the implanted active medical equipment with metal shell.
Referring to Fig. 4, the wireless charging localization method includes：
S41, detects whether the magneto sensor being arranged on inside and outside the charge coil is triggered.
In the present embodiment, the magneto sensor, which is triggered, is meant that, the magneto sensor detects that implanted is active
The metal shell of Medical Devices it is close.
S42 if the magneto sensor for being arranged on the inside of the charge coil is triggered, and is arranged on the charge coil
The magneto sensor in outside be not triggered, then current location is exactly the plant of the implanted active medical equipment with metal shell
Enter position.
The close of the metal shell is detected if placed at the magneto sensor of the inside of the charge coil, and is set
It puts the magneto sensor in the outside of the charge coil and does not detect the close of the metal shell, then illustrate to perform
The external wireless charging positioning device of wireless charging localization method is in implantation, having the implantation of metal shell
Formula active medical equipment accurate contraposition.That is, complete the active doctor to implanted using the wireless charging positioning device
Treat the positioning of equipment.
