Description
Technical Field
The invention relates to the field of medical instruments, in particular to a data transmission method and system for implantable medical equipment and an SoC chip.
Background
Implantable medical devices can be classified into both passive and active types. Most passive implantable medical devices are non-electronic products such as contact lenses, heart stents, artificial valves, artificial joints, and other tissue structure devices. Active implantable devices, such as implantable cardiac defibrillators and cardiac pacemakers, require energy supplies to replace or improve the function of an organ or to treat a disease. Currently, devices such as implantable cardiac defibrillators and cardiac pacemakers sustain the life of millions of heart disease patients. Other stimulation systems have been used to treat a variety of problems, such as urinary incontinence and chronic pain, and deep brain stimulation devices have also been used to treat diseases such as insanity, spasmodic shock and parkinsonism. Although these products are currently not used on a large scale, they will certainly be used more widely in the near future.
Implantable medical electronics are generally composed of two main parts, an in-vivo implanted part and an in-vitro measurement and control part. The task of the extracorporeal part is to measure and control the information of the human body, thereby completing the diagnosis and treatment of diseases. The whole device comprises the functions of information acquisition, processing, archiving, control, instruction, display and recording. The external part of the body is the same as a common medical instrument, and the characteristics of the system are mainly focused on the implanted part and the exchange of information and energy inside and outside the body. The implanted medical electronic equipment needs energy supply to work, and the energy supply mode of the implanted medical electronic equipment comprises two modes of power supply of an implanted battery and power supply of an external power supply. The battery-powered implantable medical device, which is a component of the implantable medical device, limits the service life of the implantable medical device, i.e., the life of the battery itself determines the life of the medical device. In addition, there is also a method of supplying power from an external power source.
Advances in rechargeable battery technology with respect to the energy supply of implantable medical electronics have facilitated the development of a variety of implantable medical electronics that are powered by in vivo rechargeable batteries. High energy density lithium polymer batteries and thin film batteries are likely to become the first choice for future implanted batteries, and energy supply is realized by utilizing other energy conversion in vivo. The conventional SoC chip of the implantable medical device is a core structure thereof, and generally includes a processor, a data collector, a backup memory and a wireless communication module, and is powered by an energy collector. However, due to the energy harvester, there are problems of unstable power supply and data transmission failure, which may lead to system failure and data overload of the implantable medical device.

Preferably, before backing up the data collected by the data collector to the backup memory, the method further comprises backing up transmission configuration parameters of the data to the backup memory, wherein the transmission configuration parameters are used for data transmission configuration between the wireless communication module and the external device. The backup of the transmission configuration parameters is used for the wireless communication module to retransmit when the transmission fails or the program has an error, and even if the processor has an abnormality, the transmission configuration parameters are already backed up in the backup memory, so that the configuration of data transmission can be well restored.
Preferably, the custom instruction is used for backing up the data acquired by the data acquisition unit from the internal data storage to the backup storage, and simultaneously starting the emergency standby power supply module to ensure the power supply of the wireless communication module until the data transmission of the wireless communication module is completed.

Step 102: monitoring the wireless communication module through a processor of the implanted medical equipment so as to periodically obtain the real-time transmission state of the data of the implanted medical equipment and the external equipment and store or update the real-time transmission state into a backup memory;
preferably, the real-time transmission state includes at least initialization, idle, transmission, reception, and transmission completion states of the wireless communication module. The backup of the real-time transmission state can be more favorable for mastering whether the transmission is finished or not and whether retransmission is necessary or not.
Step 103: the processor of the implanted medical equipment judges whether the wireless communication module receives the successful data receiving information fed back by the external equipment;
104, if the processor of the implanted medical equipment judges that the wireless communication module receives the successful receiving information fed back by the external equipment, erasing the backup data, otherwise, executing the step 105;
step 105: and if the receiving success information fed back by the external equipment is not received within the preset time, the wireless communication module reads the data from the backup memory and retransmits the data.
Preferably, if the reception success information fed back by the external device is not received within the preset time, the processor of the implanted medical device sends the identifier of the backup data and the real-time transmission state to the external device for confirmation, and then sends the failure data in a targeted manner, so as to avoid redundant sending. The external equipment can determine whether the data is received or not through the identification of the backup data, and the real-time transmission state can enable the external equipment to know whether the transmitted program is normally executed or not. The method and the device can be beneficial to judging whether the data is really required to be retransmitted or not, and avoid power consumption waste caused by redundant retransmitted data.

Preferably, the preset time can be set through calculation according to the application scene of the implantable medical device and the biological parameters of the human body.
