Mark in the above-mentioned accompanying drawing is as follows:
Embodiment
(embodiment 1)
See Fig. 1, the micro-power supply used inside human body of present embodiment comprises rubber bag tank 1, rubber column 2, stainless steel tube 3, film thermocouple 4, tepor difference electric organ 5, wireless launcher 6, signal processing system 7, high ultrasonic absorption coefficient liquid 8 and electrode 9.
Each assembly all adopts biomaterial to make, and wherein the material of stainless steel tube 3 is the medical stainless steel material, and the material of rubber bag tank 1 and rubber column 2 is medical RTV silicon rubber, and rubber cement is the medical grade silicon rubber binding agent.High ultrasonic absorption coefficient liquid 8 can be selected edible peanut oil for use, and its ultrasonic absorption coefficient is much larger than tissue.
Tepor difference electric organ 5 is made up of 3 to 20 thermo-electric generation unit.Owing to, do not allow little power supply inside that very high temperature is arranged at inside of human body.Under the little situation of the temperature difference, single thermo-electric generation unit is difficult to meet the demands, for obtaining required voltage, electric current, and need be with the unit parallel connection of a plurality of thermo-electric generations, series connection or series-parallel connection.
See Fig. 2, when the micro-power supply used inside human body of present embodiment uses, also need some external assemblies, comprise ultrasonic wave emitting head 13 and relevant device 14.This relevant device 14 comprises temperature signal receiving equipment and ultrasonic signal control appliance.
[0018]The ultrasonic signal control appliance is mainly used in hyperacoustic generation, control and demonstration.The design reference medical supersonic diagnosis of ultrasonic wave emitting head 13 and relevant device 14, therapeutic equipments.For adapting to the needs of human body different tissues, organ, the frequency that can diagnose, treat according to medical supersonic disposes a plurality of ultrasonic wave emitting heads, thereby obtains different supersonic frequencies.
For example, when the micro-power supply used inside human body of present embodiment is used for intestinal inspection, earlier to those who are investigated according to the preparation of being correlated with of B ultrasonic intestinal inspection.
According in the body with voltage, electric current, the power requirement of little medicine equipment 10, select the thermo-electric generation unit of suitable quantity, tepor difference electric organ 5 is formed in series, parallel or series-parallel connection.37 ℃ of body temperatures, the highest 42 ℃ (in the enteron aisle, temperature can suitably improve 1 degree again), output voltage 2V, the output current 0.5mA of generally being controlled at of edible peanut oil temperature.
Finish the assembling (determining its diameter and length) of the interior little power supply of human body of present embodiment then according to the situation of human body intestinal canal.Inject edible peanut oil 8 in the inner chamber of rubber bag tank 1, sealing even if edible peanut oil 8 is revealed to some extent, also is harmless to human body.Should little power supply and 10 combinations of little medicine equipment after, according to existing digestive tract examining capsule working method, the assembly of whole little medicine equipment 10 and little power supply is swallowed in the mouth, make it enter enteron aisle along digestive system.
Then coat the used ultrasonic coupling liquid 12 of ultrasonic examination, detect the position of this little power supply with ultrasonic wave emitting head 13 on tissue 11 surfaces.Because difference such as the acoustic impedance of medical stainless steel and tissue and medical RTV silicon rubber, edible peanut oil are very big, therefore on the interface of medical stainless steel, ultrasonic wave is all reflections almost, and this little power supply position in enteron aisle is easy to be detected.With reference to ultrasound diagnosis, selecting ultrasonic frequency is the ultrasonic wave emitting head of 3.5MHz, and the ultrasonic wave sound intensity is 5W/cm
2
Launch ultrasonic wave with relevant device 14 in human body, ultrasonic wave enters in the silicon rubber capsule 1 through ultrasonic coupling liquid 12 and tissue 11, and is absorbed by the edible peanut oil in the rubber bag tank 18, is converted to heat, and edible peanut oil 8 temperature are raise.Because the hot junction of tepor difference electric organ 5 is arranged in the edible peanut oil 8 of high temperature, cold junction is arranged in the rubber column 2 of low temperature, according to thermoelectric effect, has produced thermoelectric potential in the tepor difference electric organ 5, forms little power supply.Power to little medicine equipment 10 by electrode 9.Film thermocouple 4 in little power supply constantly is delivered to temperature signal signal processing system 7, signal processing system 7 is transmitted into external temperature signal receiving equipment by wireless launcher 6 again, the temperature signal receiving equipment is given the ultrasonic signal control appliance with this signal conveys, controls hyperacoustic sound intensity and the phonation time that the ultrasonic wave emitting head is sent by the ultrasonic signal control appliance.If temperature to 43 ℃, then hyperacoustic sound intensity changes 8mW/cm into
2, only detect the position of little medicine equipment 10.If temperature drops to 37 ℃, just hyperacoustic sound intensity is returned to 5 W/cm
2Along with moving of little medicine equipment 10 and little power supply, corresponding mobile ultrasonic wave emitting head 13 repeats the process of above-mentioned energy supply in vitro again.
