Technical field
The present invention relates to the implantable medical device field, especially have the implanted active electronic device and the implantation type electric stimulation system of current foldback circuit.
Background technology
In the prior art, comprise that the electric stimulation of implanted active electronic device has obtained application more and more widely as treatment or prophylactic a kind of means.Implantation type electric stimulation system generally includes implantable cardiac electric stimulation (being commonly called as cardiac pacemaker) and implantable nerve electric stimulation, mainly comprises the pulse generator, electrode and the external control device that implant.Wherein, Pulse generator is connected with electrode; Thereby the burst transmissions that pulse generator produced is arrived electrode, and the pulse signal that pulse generator produces transfers to heart by electrode or electricity irritation is carried out at specific neural position, thereby makes function of human body return to the state of normal operation.
Because pulse generator is the intravital active electronic device of implant into body; And the inner power supply of pulse generator is generally the bigger lithium battery of capacity;, the inner control circuit of pulse generator must guarantee that electric current can not be excessive when breaking down (like short trouble), otherwise the safety that will cause battery and the heating of pulse generator shell to threaten patient.
Implantation type electric stimulation system does not in the market all have the overcurrent defencive function.In order to address the above problem, can prevent that the excessive generation of electric current is overheated through the method for series limiting resistor between power supply and main circuit board.Yet adopt this method to make the active voltage of internal control circuit of pulse generator just descend, increased meaningless energy consumption and shortened service life of Implantable Pulse Generator.Other has a kind of overcurrent protection solution; The fuse of between power supply and main circuit board, only connecting; Fuse failure makes system's power failure when big electric current appears in system; Though can prevent effectively that implantable medical equipment from producing overheatedly causes danger to patient, because the interruption of system's power supply makes it can't keep due function, practical value is little for implant patient.
Summary of the invention
To the deficiency that exists in the prior art, the technical problem that the present invention will solve provides a kind of implanted active electronic device with current foldback circuit, and energy consumption was less when it can guarantee when fault, not produce excessive electric current and operate as normal.
According to a kind of technical scheme provided by the present invention; A kind of Implantable Pulse Generator with current foldback circuit; The current foldback circuit module and the main circuit module that comprise power supply, be in series with said power supply, said current foldback circuit module comprise current-limiting resistance and the fuse that is in parallel with said current-limiting resistance.Fuse described in this description is meant when blowout current surpasses certain value, device that can automatic shutoff circuit.
Preferably, said fuse is disposable fusing electric fuse or resettable fuse, the two kinds of equal ability of electric fuse moment disconnecting circuits when big electric current occurring.If after just instantaneous large-current and fault were got rid of automatically, resettable fuse also can recover minimum resistance automatically when electric current recovers, need not the manual work replacing.
Preferably, the blowout current scope of described fuse is 10～500 milliamperes.
Preferably, the Standard resistance range of described current-limiting resistance is 5～50 ohm.
Preferably, this active electronic device is an Implantable Pulse Generator.
Preferably, this active electronic device is implantable sensor system or implanted actuator system.
Another technical problem that the present invention will solve provides a kind of implantable nerve electric stimulation with current foldback circuit, comprises the as above described pulse generator of claim.
Preferably, this implantable nerve electric stimulation is a kind of in implanted brain deep electric stimulation, implanted cortex electric stimulation, implanted spinal cord stimulation trial system, implanted sacral nerves electric stimulation or the implanted vagus nerve electric stimulation.
The present invention also provides a kind of implantable cardiac pacing system with circuit overcurrent protection, comprises aforesaid Implantable Pulse Generator.
The present invention also provides a kind of implanted rhythm of the heart with circuit overcurrent protection to change multiple defibrillation system, comprises aforesaid Implantable Pulse Generator.
Advantage compared with prior art of the present invention is: because the current foldback circuit module of between the main circuit module of implanted active electronic device and power supply, having connected and having been composed in parallel by current-limiting resistance and fuse; When system's operate as normal; The fuse of electric current in overcurrent holding circuit module forms the loop, because the power consumption of the extremely low system of fuse resistance is also very low; When system breaks down when being short-circuited (puncturing like excessive, the non-critical piece of leakage current) like the main circuit module; When electric current increases greater than the blowout current of fuse; Fuse failure, electric current forms the loop via current-limiting resistance, has avoided internal system the health that super-high-current causes the battery heating to jeopardize implant patient to occur; Guaranteed that simultaneously the active electronic device still has certain function, such as stimulatory function.
