Description
Technical field
This utility model relates to a kind of armarium, be specifically related to a kind of medical blast wave generating apparatus, this device can be used for external stone crushing, and treatment urinary system or biliary system calculus can also be used for the treatment of the diseases such as scapulohumeral periarthritis, bone does not connect, bony spur hypertrophy of orthopaedics.
Background technology
In the prior art, medical blast wave generating apparatus has electrohydraulic type, back to focus on multiple structures such as electromagnetic type, self-focusing electromagnetic type.The electrohydraulic type blast wave generating apparatus is to utilize electrode high-voltage pulse discharge under water, produces shock wave, focuses on through the spheric reflection body then and forms the some impact energy.This device has the following disadvantages: 1, because electrode discharge produces intensive electric arc and noise, make the patient feel high-pressure in treatment; 2, patient of every treatment must change an electrode, and electrode life is short, treatment cost height; 3, the required precision of spheric reflection body is very high, and difficulty of processing is big, the manufacturing cost height.
It is to utilize plane solenoid and plane diaphragm to produce shock wave that the back focuses on the electromagnetic shock-wave generating means, and the lens focus through the place ahead forms the surge energy again.This device is owing to adopt the energy attenuation loss of lens focus shock wave bigger, thereby influences therapeutic effect.
Immediate with this utility model is the self-focusing electromagnetic type impact wave generating means, and this device utilizes sphere solenoid and sphere vibrating diaphragm to produce shock wave, and the focus place focuses on a formation point impact energy forwardly.Its structure mainly is made up of chassis, solenoid and metal vibrating diaphragm (as copper etc.), and the chassis is provided with a concave surface, and the solenoid coiling is fixed on the concave surface, and fixedly concave metal vibrating diaphragm is close in the solenoid outside.For the fixing metal vibrating diaphragm, on the outer rim around the vibrating diaphragm, be provided with outward extending gulde edge, during installation gulde edge is pressed abd fixed on the chassis edge.In order to help the vibration of vibrating diaphragm, also leave molding tongue or groove between vibrating diaphragm concave part that has and the gulde edge, make vibrating diaphragm have better degree of freedom.However, but this in actual applications structure still makes the vibration of vibrating diaphragm be subjected to pining down more greatly, influences the accumulation of energy and the waveform of shock wave, thereby influences therapeutic effect.In addition, because the metal vibrating diaphragm directly contacts with water body, cause the corrosion of water body on the one hand to the metal vibrating diaphragm, on the other hand in the shock wave generating process, the gas that produces can be adsorbed on the metal vibrating diaphragm, at first, increased energy loss, the secondly damage that can cause the metal vibrating diaphragm of the cavitation effect in shock wave takes place.
Summary of the invention
The utility model proposes a kind of free diaphragm-vibrating type self-focusing surge generator, its objective is in order to reduce because of the fixing influence that brings to accumulation of energy and waveform in vibrating diaphragm edge.
For achieving the above object, the technical solution adopted in the utility model is: a kind of free diaphragm-vibrating type self-focusing surge generator, comprise pedestal, solenoid and metal vibrating diaphragm, pedestal is provided with a self-focusing concave surface, the solenoid coiling is fixed on the concave surface, one end of solenoid is as high-pressure side, the other end is as earth terminal, a self-focusing concave metal vibrating diaphragm is close in the solenoid outside, one deck dielectric film is posted in the metal vibrating diaphragm outside, this dielectric film edge is outward extended with gulde edge, and gulde edge is fixed on the pedestal.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described self-focusing concave metal vibrating diaphragm is a spherical crown surface shape.
2, in the such scheme, described dielectric film bedding makes to constitute a vacuum chamber in the concave surface on the concave surface of pedestal uncovered, and pedestal is provided with an air entry, and this air entry is communicated with vacuum chamber.
This utility model operation principle is: utilize dielectric film by the mode of evacuation metal vibrating diaphragm and solenoid to be fixed on the concave surface of pedestal, can significantly reduce pedestal pining down like this to vibrating diaphragm, make the metal vibrating diaphragm be in relative free state, help the free vibration under the solenoid effect of metal vibrating diaphragm.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1, because this utility model is fixed on metal vibrating diaphragm and solenoid on the concave surface of pedestal with dielectric film, make vibrating diaphragm be in relative free state, do not pind down, the shock wave energy decay that therefore produces is minimum, and waveform is best.Compared with prior art, both improve waveform and reduced energy loss.
2, this utility model adopts the self-focusing diaphragm structure of boundless slotless, has given full play to the advantage of self-focusing electromagnetic type impact wave generator, has overcome the deficiencies in the prior art.
3, this utility model is isolated medium and metal vibrating diaphragm by dielectric film, has avoided the corrosion of water body to the metal vibrating diaphragm on the one hand, has overcome the damage that because of cavitation effect the metal vibrating diaphragm is caused during shock wave takes place on the other hand.
4, this utility model vibrating diaphragm simple shape is easy to processing, guarantee the sphere precision easily, and processing cost is low, long service life.
5, this utility model low cost of manufacture, the self-focusing performance is good, and energy attenuation is few, and therapeutic effect is good.
