Description
Technical field
This utility model relates to the sonicator in a kind of medical apparatus and instruments, particularly a kind of reflection type ultrasonic therapeutic instrument.
Existing sonicator mainly contains three parts to be formed, power pack, high frequency amplifier section, transducer portion, and power supply is connected ultrasonic transducer with the high frequency amplifier part by cable.In order well to be coupled with the human body therapy part, the transducer front end need be joined the matching layer that metal is made.This technology constitutes relatively than the component difficulty height, thereby makes cost too high, is difficult to apply.And because the metal matching layer makes the sound field skewness, acoustic pressure very high meeting in centre makes user tingle, or bad because of being coupled, and metal heat-conducting heating soon can cause scald.In the existing in addition ultrasonic technique, technology, circuit that ultrasound atomizer adopts are simple, mostly adopt the bikini oscillating circuit directly to drive piezoelectric chip generation ultrasound wave and make water atomization, but this technology can not be applied in treatment physical therapy aspect.Reason is that ultrasonic piezoelectric chip can not be dried up at work, in case dried up, the electric current in the circuit increases to immediately is enough to burn out circuit, work in the water ultrasound wave peak value that produces of piezoelectric chip is very high in addition, user can be felt very twinge, so can not directly apply to the treatment physical therapy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reflection type ultrasonic therapeutic instrument, it has solved the problem that there is the sound field skewness in existing sonicator, the centre acoustic pressure is very high and user is tingled or scald, and it has also solved existing sonicator and has had complex structure, problem that cost is high.
The technical solution of the utility model is achieved in that it comprises transducer and drive circuit, transducer is connected by the high frequency multicore cable with drive circuit, it is characterized in that: transducer is isolated into the degas sump and the air bin of mutual sealing by the dividing plate that piezoelectric chip is housed, degas and be full of the sound-guiding liquid body medium in the sump, reflecting plate is equipped with in degas sump bottom, the sump top of degassing has the hole, be stamped sound passing membrane on the hole, the electrode wires of piezoelectric chip is connected with the high frequency multicore cable, and drive circuit adopts the control of bikini oscillating circuit.The sound-guiding liquid body medium that transducer degass in the sump is acoustic conductive medias such as the water that degass, liquid paraffin; Piezoelectric chip becomes to be arranged vertically with sound passing membrane, and the axis of reflecting plate becomes miter angle to arrange with piezoelectric chip respectively with sound passing membrane; The reflecting surface of reflecting plate is protruding sphere, different with using, protruding spheric curvature is provided with difference, the angle of scattering difference of reflection, can be applied to treatment, physical therapy or beauty treatment respectively, the housing of reflecting plate and transducer and the reflecting plate on the housing support the air back of the body of forming a sealing; U type relief pipe is housed in the air bin, and the relief pipe two ends are inserted in the jack on the dividing plate, and communicate with the sump that degass; Piezoelectric chip is fixed by chip support and wafer trim ring; Degas and anhydrous shield electrode is housed in the sump, it is fixed on the dividing plate.
This utility model adopts the reflection type ultrasonic structure, sound field is evenly distributed, each position sound pressure equalization.Can prevent to scald, no sensation of pricking, the utlity model has simple in structure, safe ready, advantage that cost is low, can be widely used in treatment, physical therapy and beauty treatment.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
As Fig. 1, shown in Figure 2, it comprises transducer and drive circuit this utility model, transducer is connected by the high frequency multicore cable with drive circuit, transducer is isolated into the degas sump 1 and the air bin 19 of mutual sealing by the dividing plate 11 that piezoelectric chip 17 is housed, degas and be full of the sound-guiding liquid body medium in the sump 1, reflecting plate 3 is equipped with in sump 1 bottom of degassing, the sump top of degassing has the hole, be stamped sound passing membrane 7 on the hole, close circle 5 of sound passing membrane 7 usefulness and pressure ring 6 are pressed on it on housing 4, sound passing membrane 7 uses the plastics manufacturing, its thickness is much smaller than hyperacoustic wavelength, and when ultrasound wave saw through, power loss was very little like this, the electrode wires 15 of piezoelectric chip 17 is connected with high frequency multicore cable 16, and drive circuit adopts the bikini oscillating circuit.The sound-guiding liquid body medium that transducer degass in the sump 1 is water, liquid paraffin or leads sound oil; Piezoelectric chip 17 is arranged vertically for 7 one-tenth with sound passing membrane, and the axis of reflecting plate 3 is arranged with 7 one-tenth miter angles of piezoelectric chip 17 and sound passing membrane respectively; The reflecting surface of reflecting plate 3 is a sphere, with using different protruding spheric curvatures difference is set, and the angle of scattering difference of reflection can be applied to treatment, physical therapy or beauty treatment respectively; Reflecting plate 3 carries on the back 2 with the air that a sealing is formed in the housing 4 and the support of the reflecting plate on the housing 20 of transducer, is beneficial to ultrasonic reflections; Because piezoelectric chip can produce heat when work, degassing the water that degass of sump 1 can flatulence of heat type, water volume can increase intrinsic pressure meeting and increase, so U type relief pipe 13 is housed in air bin 19, relief pipe 13 two ends are inserted in the jack 18 on the dividing plate 11 by decompression joint 12, and communicate with the sump 1 that degass, relief pipe 13 is an elasticity elastomeric material preferably, the hydro-thermal of degassing is unlikely to make the sump 1 that degass intrinsic pressure excessive when expanding.Piezoelectric chip 17 is fixing by chip support 9 and wafer trim ring 10; Degas and anhydrous shield electrode 8 is housed in the sump 1, it is fixed on the dividing plate 11, and anhydrous shield electrode 8 is connected with high frequency multicore cable 16 by anhydrous shield electrode line 14.As shown in Figure 3, the work of bikini oscillating circuit makes piezoelectric chip 17 vibrations send ultrasound wave to reflecting plate 3 reflections, scattering, turn 90 degrees to sound passing membrane 7, sound passing membrane 7 effectively contacts with human body during treatment, and ultrasound wave just can be transmitted to inside of human body, because the scattering process of reflecting plate convex surface, acoustic pressure no longer focuses on the center, make the people not have sensation of pricking, owing to use the plastics sound passing membrane, so and the plastic hot conduction does not have the phenomenon of scald slowly.Thereby reach the purpose of treatment, physical therapy, beauty treatment safely and effectively.
