Description

The invention relates to an acoustic wave and a seismic wave conducting medium, in particular to an acoustic wave and seismic wave conducting gasket for ultrasonic diagnosis and treatment, which can be applied to an ultrasonic wave, a seismic wave crushing stone and a gel-coated liquid-permeable probe ( Probe) A non-invasive procedure for eroding the human body.

Around 1921, France produced an ultrasonic detector. During the Second World War, with the development of SONAR (sound of navigation and range), industrial ultrasonic crack detectors were used to detect the location of fish schools. In terms of power, the processing machine and the washing machine are the center. This has caused a surge in ultrasound. The efforts of physicians and engineers, coupled with the development and improvement of piezoelectric crystals, have made instruments more sophisticated and meet the requirements of clinical diagnosis. Ultrasound is a very important nonr invasive diagnostic tool for medical diagnosis. It can directly observe the anatomy of the human body and the movement of the organ and is almost harmless to the human body.

In the whole life, about 9.3% of the population had calculi in the urinary tract.

Quantity, if the amount of water in the urine is too small, the concentration of these ingredients in the urine naturally increases, and it is easy to precipitate into stones. Other causes of stones include factors such as metabolic abnormalities in the body, family genetic factors, urinary inflammation, and structural abnormalities in the urinary system. Therefore, stone treatment is a very important part of the urologist's practice program. There are two types of calculus surgery: "invasive treatment" and "low invasive treatment." The former includes traditional atherectomy, soft or rigid ureteroscopic lithotripsy, cystolithic lithotripsy, and percutaneous nephrolithotomy; the latter is extracorporeal shock wave lithotripsy.

吋, usually using silica gel solution

The probes are tightly connected to allow ultrasonic or seismic waves to enter the body. In addition, silica gel can also reduce the friction between the skin and the probe. The position and amount of silicone coating will affect the effect of ultrasonic development and shock wave lithotripsy. Although the silica gel currently used by ultrasonic or seismic waves greatly improves the problem of the connection between the ultrasonic or seismic probe and the skin is not tight. However, the main disadvantage of using silica gel as a coupling agent is that the probe is in direct contact with the human body. It is only isolated by silica gel. When the doctor is performing an ultrasonic or shock wave lithotripter ^, if the wound is accidentally caused, the body fluid and blood will flow out. Mixed on the silicone fluid and the probe, the doctor may simply wipe it with a tissue and use it on the next patient, which is easy to cause fluid and blood transmission between the patients, which is safe and hygienic.

Another disadvantage of using silicone is that the coating solution is on the patient's skin. The icy feeling can cause discomfort to the patient, and as the probe moves, the silicone coating is full of the body. After the medical procedure is finished, usually only a few sheets of paper are provided for the patient. Wiping by yourself, most of the time will be because the paper towels or ^ is not enough. Furthermore, the disadvantages of expensive silica gel, the inability to reuse, and the inconvenience of using a large amount of paper to be removed after use are problems that are currently in need of resolution.

When the conductive medium 43 is the acoustic wave and seismic wave conducting spacer 10 of the present invention, the number of pulses is further reduced to 350 times. From this result, it is understood that the seismic wave transmission effect of the acoustic wave and shock wave transmission pad 10 of the present invention is superior to that of the conventional ultrasonic silica gel. Please refer to FIG. 5. FIG. 5A is an image taken from the kidney using a conventional ultrasonic gel, and FIG. 5B is an image taken on the kidney using the sonic and seismic wave spacer 10 of the present invention. As is apparent from comparison between Fig. 5A and Fig. 5B, the conventional ultrasonic wave gel and the acoustic wave and seismic wave conducting pad 10 of the present invention are identical in image. As shown in Fig. 6, the acoustic wave and seismic wave conducting gasket 10 can be placed in a package 60 for storage. The package bag 60 preferably has four press-fit sides 601 to form an accommodation space for receiving the acoustic wave and seismic wave conducting pads 10.
