Abstract

A medical monitor is disclosed for implantation in a human body for monitoring biological activity and states as detected by implanted sensors. The medical monitor includes an enclosure surrounding at least one hard disk drive, and also includes a transmitter and a receiver for producing and transmitting signals in the radio frequency range. The medical monitor is in communication with the sensors, by which information on biological activity and states is stored on the one or more hard disk drives. It also includes a recharging system including at least one rechargeable battery and an induction electronics interface.

Claims

1. A medical monitor for implantation in the user'"'"'s body for monitoring data on biological activity and states gathered from sensors implanted in the user'"'"'s body, said medical monitor comprising:

an enclosure surrounding at least one hard disk drive, which is adapted to be implanted in a user'"'"'s body, said medical monitor including a transmitter and receiver for producing and transmitting signals in the radio frequency range;

said medical monitor being in communication with said sensors, by which information on biological activity and states is stored on said at least one hard disk drive;

a recharging system including at least one rechargeable battery and an induction electronics interface; and

an electrical grounding system which includes an external grounding wire which is connected to one of the user'"'"'s shoes.

2. The medical monitor of claim 1, wherein:

said induction electronics interface includes an external charger having an external power coil; and

a subcutaneous power coil implanted in the user'"'"'s body and electronically connected to said at least one rechargeable battery, whereby power is inductive transferred to recharge said rechargeable batteries.

3. The medical monitor of claim 2, wherein:

said external charger includes a sensor for locating said subcutaneous power coil.

4. The medical monitor of claim 2, wherein:

said subcutaneous power coil is located within said enclosure of said medical monitor.

5. The medical monitor of claim 2, wherein:

said subcutaneous power coil in located outside said enclosure of said medical monitor.

6. The medical monitor of claim 1, wherein:

said at least one hard disk drive includes a sleep-mode and drive performance software module to minimize power expenditure.

7. The medical monitor of claim 1, wherein:

said at least one hard disk drive includes a CPU which performs periodic checks of the power level of said at least one rechargeable battery, and which can initiate an alert if said level is found to be low.

8. The medical monitor of claim 7, wherein:

said alert initiated by said CPU is sent by said radio frequency transmitter to medical personnel.

9. The medical monitor of claim 7, wherein:

said alert initiated by said CPU is sent by an alert mechanism.

10. The medical monitor of claim 9, wherein:

said alert mechanism includes a buzzer.

11. The medical monitor of claim 9, wherein:

said alert mechanism includes a vibration motor.

12. The medical monitor of claim 9, wherein:

said alert mechanism includes a piezo micro-speaker.

13. The medical monitor of claim 12, wherein:

said at least one hard disk drive includes a text to speech algorithm and said alert mechanism transmits voice messages through said piezo micro-speaker.

14. The medical monitor of claim 9, wherein:

said alert mechanism is a local alert located within said enclosure of said medical monitor.

15. The medical monitor of claim 9, wherein:

said alert mechanism is a remote alert which is located outside of said enclosure of said medical monitor, but adapted to be within the body of the user.
