Problems solved by technology

However, since the heart is the "engine" of the human body, improper collection of cardiac kinetic energy will inevitably affect the function of the heart and even cause heart damage
In addition, traditional electromagnetic induction generators based on Faraday's law are large in size and complex in structure, and are not suitable for implantation in the body.

Embodiment 1

[0029] figure 1 It is a schematic diagram of the implantable bioenergy blood glucose monitor according to the first embodiment of the present invention. like figure 1 As shown, the implantable bioenergy blood glucose monitor 100 includes a blood glucose sensor 19 , a signal transmitting part 16 , a power generating part 200 , and a signal receiving part 300 located outside the body. The power generation unit 200 includes a power generation body 11 , an output electrode 14 , a rectification filter circuit 12 and an electric energy storage unit 13 . The power generating body 11 is an elastic annular structure, which can surround the aorta 18. The power generating body 11 has a piezoelectric material inside, which can generate electric energy by utilizing the deformation of the aorta. The output electrode 14 of the power generation main body 11 is connected with a rectification filter circuit 12, so that the electric energy output by the power generation main body 11 becomes st...

Embodiment 2

[0041] In this embodiment, the shape of the blood glucose sensor, the signal transmitting part, the power generation body and the setting of the adjustment end of the implantable bioenergy blood glucose monitor are the same as those in Embodiment 1, the difference is that in this embodiment, the piezoelectricity of the power generation body The material layer adopts nanoscale piezoelectric ceramic material.

[0042] Another difference is that in this embodiment, the adjustment end is fixed with a titanium clip.

Embodiment 3

[0044] In this embodiment, the shape of the blood glucose sensor, the signal transmitting part, the power generation body and the setting of the adjustment end of the implantable bioenergy blood glucose monitor are the same as those in Embodiment 1, the difference is that in this embodiment, the piezoelectricity of the power generation body The material layer is made of piezoelectric polymer, and the adjustment end is fixed by adhesive bonding.

Abstract

The invention provides an implantable biological energy blood glucose monitor. The implantable biological energy blood glucose monitor comprises a sensor for monitoring blood glucose levels, a signal transmitting unit, a signal receiving unit and a power generation unit. The power generation unit comprises a power generation body, adjusting ends, an output electrode, an electrical energy storage unit and an encapsulation layer. The power generation body is used for wrapping an aorta. The power generation body is of a multilayer film structure and comprises a piezoelectric material layer arranged on the central layer as well as a first electrode layer and a second electrode layer which are arranged on both sides of the piezoelectric material layer. The adjusting ends are arranged at both ends of the power generation body for adjusting the length of the power generation body. The output electrode is used for transport electrical energy to the electrical energy storage unit. The electrical energy storage unit is used for storing electrical energy and supplying the blood glucose sensor and the signal transmitting unit with power. The encapsulation layer covers the surfaces of the power generation body, the adjusting ends and the output electrode. The implantable biological energy blood glucose monitor does not need to use batteries as a power source.

Description

technical field [0001] The invention relates to an implantable bioenergy blood glucose monitor, which belongs to the field of medical equipment. Background technique [0002] Diabetes is a common and frequently-occurring disease in middle-aged and elderly patients. As a life-long disease, there is still a lack of radical treatment. Patients usually require regular venous blood draws to monitor blood sugar levels. The implantable blood glucose monitor can monitor the blood glucose concentration in the tissue in real time, without the need for invasive blood tests every time. However, no matter what type of implantable blood glucose monitor, it needs to use implantable tiny batteries to provide power. Once the battery power is depleted, another surgery is required to replace the battery. It will not only cause physical and mental pain to patients, but also increase the financial burden on patients and their families. [0003] Inside the human body, both the contraction of ...
