Patient controller and implanted medical system

Abstract

The invention discloses a patient controller used for accurately controlling a magnetic switch in an implanted medical device. A stimulating on / off button and a speed-up interception button are arranged on the patient controller. When a patient presses the stimulating on / off button, a first timer is triggered so that an electromagnet is effective in three seconds and then the implanted medical device is capable of judging that the patient sends out an off stimulating output signal according to the time; and when the patient presses the speed-up interception button, a second timer is triggered so that the electromagnet is effective in one second and then the implanted medical device is capable of judging that the patient sends out a rapid interception signal according to the time and thus the pull-in time of a reed switch is controlled accurately so that the patient can be helped in judging whether the patient controller is used in an off stimulating output mode or in a rapid interception mode and thus error judgment of the implanted medical device is prevented and operation and use is facilitated for the patient. The invention also discloses an implanted medical system which includes the patient controller.

Description

technical field [0001] The invention relates to an implanted medical system, in particular to a patient controller and an implanted medical system for accurately controlling a magnetic switch in an implanted medical device. Background technique [0002] Implantable medical systems usually include implantable electrical nerve stimulation systems (including deep brain electrical stimulation DBS, implantable cerebral cortex stimulation CNS, implantable spinal cord electrical stimulation SCS, implantable sacral nerve electrical stimulation SNS, implantable Vagus nerve stimulation VNS, etc.), implantable cardiac electrical stimulation system (commonly known as cardiac pacemaker), implantable drug infusion system (IDDS), etc. [0003] Taking the implantable electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body, electrodes and a controller outside the body. Among them, the pulse generator is connected to the electrode through...

Problems solved by technology

[0006] However, since the energy of the battery in the implantable medical device of the implantable medical system is limited, if the wireless communication module of the implantable medical device is always on High-power working conditions and large energy consumption will greatly shorten the service life of implanted medical devices. For patients, they not only have to bear the high cost of replacing implanted medical devices, but also bear the pain of surgery.
