Specific embodiment
It will be explained in detail therapeutic equipment provided in an embodiment of the present invention below.
It is the overall structure diagram of current therapeutic equipment referring to Fig. 1, the tubular shell including filling acoustic conductive media 106 is led
Acoustic medium 106 has the first opening 101 and the second opening 102, is respectively arranged with the at the first opening 101 and the second opening 102
One sealed membrane 103 and the second sealed membrane 104, the supersonic generator 105 are placed in the ultrasonic wave that it is generated at the second opening 102
It will drive the first sealed membrane 103 contacted after saturating first sealed membrane 103 to resonate, and leading inside tubular shell
It is propagated in acoustic medium 106, to be focused.
But above-mentioned therapeutic equipment ultrasonic wave is conducted by the acoustic conductive media, is focused by the tubular shell, when focusing,
When ultrasonic projection is to tubular housing inner wall, tubular shell can absorb ultrasonic wave, cause the energy of ultrasonic wave that can lose.
In view of the above-mentioned problems, the following technical solutions are proposed by the present invention.
It referring to fig. 2, is the cross section structure schematic diagram of therapeutic equipment provided in an embodiment of the present invention;
Therapeutic equipment, comprising: taper shell 1, ultrasonic transmitter 3 and acoustic conductive media 2;
The bore of the taper shell 1 is gradually reduced along top to bottom direction;
The ultrasonic transmitter 3 is placed in the top of the taper shell 1;
Acoustic conductive media 2 is placed in taper shell 1;
The inner wall of the taper shell 1 is smooth surface and 1 inner wall of the taper shell is provided with ultrasonic reflections layer 4,
The ultrasonic reflections layer 4 is formed on 1 inner wall of taper shell according to the shape of the taper shell inner wall, surface
For smooth surface.
The therapeutic equipment that the embodiments of the present invention provide, the taper shell inner wall is provided with ultrasonic reflections layer 4, described
Ultrasonic reflections layer 4 is formed on 1 inner wall of taper shell according to the shape of the taper shell inner wall, and surface is also light
Sliding surface.
In this way, ultrasonic wave can be reflected by ultrasonic reflections layer 4 without by cone cell when ultrasonic wave reaches taper shell inner wall
Inner walls absorb or scattering, ensure that ultrasonic wave excessive will not be depleted in this way, improve the utilization rate of ultrasonic wave,
The focusing energy of ultrasonic wave is also just improved accordingly.
It is provided in an embodiment of the present invention described for sound wave reflecting layer.
The ultrasonic reflections layer can also be thin film bulk acoustic wave resonator.
When being focused on ultrasonic projection to the thin film bulk acoustic wave resonator, resonance, ultrasonic wave occur for ultrasonic wave
It is further magnified, energy obtains stronger focusing.
Specifically, the thin film bulk acoustic wave resonator can be the film that zinc oxide material is made.
Further, in order to further increase the focusing energy of ultrasonic wave, thin film bulk acoustic wave resonator bring damage is reduced
It loses.
Double-layer films bulk acoustic wave resonator can be set in the present invention, and the density of double-layer films bulk acoustic wave resonator is different, leans on
The density of the first layer thin film bulk acoustic wave resonator of nearly acoustic conductive media is less than the density of second layer thin film bulk acoustic wave resonator.
In this way, after ultrasonic wave reaches first layer thin film bulk acoustic wave resonator, if to penetrate first layer thin there are also portion of ultrasonic sound wave
Membrane body acoustic resonator reach the second layer thin film bulk acoustic wave resonator when, the second thin film bulk acoustic wave resonator can reflect ultrasonic wave to
First layer thin film bulk acoustic wave resonator, and penetrate the first layer thin film bulk acoustic wave resonator, in acoustic conductive media other are super
Sound wave meets reinforcement, further increases the energy of ultrasonic wave.
In order to further increase focusing ultrasonic wave energy, it is possible to reduce ultrasonic wave can be reinforced while the loss of ultrasonic wave
Issue energy.
Specifically, ultrasonic transmitter of the present invention includes stacked supersonic generator and ultrasonic transducer.
Ultrasonic transducer is located at the top of the taper shell, and the supersonic generator is located at the ultrasonic wave transducer
The one end at top of the device far from the taper shell, the ultrasonic wave that supersonic generator issues make by the ultrasonic transducer
It obtains ultrasonic wave to be strengthened, further improves the energy of the ultrasonic wave of supersonic generator sending.
The above description is only an embodiment of the present invention, is not intended to restrict the invention.For those skilled in the art
For, the invention may be variously modified and varied.All any modifications made within the spirit and principles of the present invention are equal
Replacement, improvement etc., should be included within scope of the presently claimed invention.
