Detailed description of the invention
The detailed description of the invention of this utility model implanted self energizing blood sugar monitoring instrument is described below in conjunction with accompanying drawing,
< embodiment one >
Fig. 1 is the generating main body of implanted self energizing blood sugar monitoring instrument in embodiment 1 is the schematic diagram of tetragon, as shown in Figure 1, implanted self energizing blood sugar monitoring instrument 20 has Power Generation Section 200, monitoring portion 17 and signal emission part 18, and for receiving the external receiving system (not shown) from signal emission part 18.Wherein, Power Generation Section 200 comprises generating main body 21, output unit, energy storage unit 16, fixed cell 22 and encapsulated layer (see figure 2).Generating main body 21 is rectangle, two narrow limits of rectangle respectively has a fixed cell 22, for generating main body 11 is fixed on visceral pericardium with long axis direction along systaltic direction.When implanting generating main body, heart is manifested by operating mode, generating main body arranged along systaltic direction and be sewn on visceral pericardium by fixed part, generating main body and visceral pericardium are fitted, and now generating electricity main body can along with the generation deformation of beating of heart.
Fixed cell 22 is made up of encapsulated layer, and the inside of fixed cell 22 does not have the electrification structure such as electrode or piezoelectric, therefore can not destroy the electrification structure of generating main body 21 when using suture to fix.Generating main body remainder except fixing with fixed cell 22 is not fixed, and is beneficial in systaltic process, make generating main body better deformation can occur.Because generating main body have employed rectangle, and installation direction is consistent with systaltic direction, therefore can well gather the mechanical energy that heart contraction produces.
Output electrode 14 exports to energy storage unit 16 for electric energy generating main body produced, before energy storage unit 16, also there is current rectifying and wave filtering circuit 15, electric current for exporting output electrode 14 carries out rectifying and wave-filtering, thus makes the electric current of output more stable.Energy storage unit 16 by supply of electrical energy to the monitoring portion 17 of implanted implanted self energizing blood sugar monitoring instrument and signal emission part 16, monitoring portion 17 reads the blood glucose value in blood in real time, and by signal emission part 16, blood glucose value is wirelessly sent to external receiving system (not shown).
Fig. 2 is the sectional view of the generating main part of the implanted self energizing blood sugar monitoring instrument of this utility model embodiment, as shown in Figure 2, generating main body 21 is multi-layer film structure, its central core is piezoelectric layer 31, piezoelectric layer 31 is made up of ZnO nanowire array, the both sides of piezoelectric layer 31 are respectively electrode layer 32 and electrode layer 33, and electrode layer 32 and electrode layer 33 are connected with output electrode 14 (not shown) respectively.Encapsulated layer 34 is positioned at the outside of electrode layer 32 and electrode layer 33, and encapsulated layer 34 has good insulating properties and biocompatibility.
Fig. 5 is the circuit diagram of this utility model embodiment, as shown in Figure 5, generating main body 21 is connected with current rectifying and wave filtering circuit 15, the electric energy that generating main body 21 produces charges to energy storage unit 16 after current rectifying and wave filtering circuit 15, and energy storage unit 16 is for powering for the blood sugar monitoring portion in electrical appliance and the present embodiment and signal emission part.
< embodiment two >
Fig. 3 is the Power Generation Section of this utility model embodiment is leg-of-mutton implanted self energizing blood sugar monitoring instrument schematic diagram, as shown in Figure 3, the generating main body 12 of implanted self energizing blood sugar monitoring instrument 11 of the present utility model is triangle, leg-of-mutton each vertex position all has a fixed cell 13, output electrode 14 is connected with electrode layer (see figure 2), current rectifying and wave filtering circuit 15 is connected with output electrode 14, and energy storage unit 16 is connected to current rectifying and wave filtering circuit 15 afterwards for storing the electric energy that generating main body 12 produces.
The shape of generating main body 12 is triangle, when being installed on visceral pericardium, utilizes the fixed cell 13 be positioned on an Atria summit generating main body 12 to be fixed on visceral pericardium.Wherein the apex of the heart is pointed on a leg-of-mutton summit, two other summit and heart and each limit leg-of-mutton of the main body 12 that generates electricity are not fixed, so both can not limit contraction and the diastole of heart, also contribute to piezoelectric layer along with the motion generation deformation of heart thus produce electric energy.
Generating main body 12 is made into the energy that leg-of-mutton advantage is more to gather heartbeat, this is because not only have horizontal contraction and diastole in the process of heartbeat, also longitudinal contraction and diastole is had, when adopting leg-of-mutton shape, a leg-of-mutton summit is set to the direction towards the apex of the heart, and two other summit is set to parallel with the direction of heart cross-direction shrinkage, no matter being heart cross-direction shrinkage is like this longitudinal contraction, generating main body 12 all can be driven to be out of shape.Therefore the leg-of-mutton shape energy that can more utilize heartbeat to produce than the shape of tetragon.
< variation >
This variation is compared with embodiment one, and except the shape of the main body that generates electricity is except Long Circle, arranging of other is all identical.As shown in Figure 4, the shape of generating main body 42 is Long Circle, and on oblong two summits, place has fixed cell 41, and the shape of generating main body 42 is that oblong advantage is do not have sharp-pointed corner, contributes to the probability reducing impair cardiac.
Certainly, the shape of the generating main body of implanted self energizing blood sugar monitoring instrument of the present utility model can be various shape, is not limited only to triangle, tetragon and Long Circle in above-mentioned two embodiments.
