Description

  The present invention relates to a sound wave and a vibration wave conductive medium, and more particularly, to a sound wave and vibration wave conductive spacer used for ultrasonic diagnosis and treatment, and after applying ultrasonic waves, vibration wave crushed stone, or silicon gel, a probe (Probe). ) Applied to non-invasive procedures that come into contact with the human body.

  Since around 1921, ultrasonic detectors have been manufactured in France. With the development of sonar (SONAR, sound of navigation and range) during World War II, it became possible to detect the position of a school of fish with an industrial ultrasonic flaw detector. In terms of power, the development centered on processing machines and washing machines. Thus, it is said that the heyday of ultrasound was reached. With the efforts of doctors and engineers, with the development and improvement of piezoelectric crystals, instruments have been made more and more precisely to the point where clinical diagnostic requirements are met. Ultrasound is a non-invasive diagnostic tool that is very important in medical diagnosis, and it can directly observe the state of human anatomy and organ movement, and it is almost non-invasive to human body. Atraumatic.

  Research has also shown that the percentage of the population who once suffered from urinary calculi in the nation's lifetime is about 9.3%. The origin of urinary stones is very complex, and the most basic cause is the formation of stones by causing crystallization when precipitates in the urinary system become supersaturated. The metabolism in the body is filtered through the kidneys, and since there is a certain amount of waste that is excreted in the urine, if the water content in the urine is too low, the concentration of these components in the urine will increase naturally. Therefore, it becomes easy to settle and a calculus is formed. Other causes of stones include factors such as metabolic abnormalities in the body, familial genetic factors, urinary inflammation, and structural abnormalities in the urinary system. For this reason, stone treatment has been considered as an extremely important part of urologists' clinical practice. There are two types of calculus surgical treatments: “invasive treatment” and “minimally invasive treatment”. The former includes traditional surgical lithotomy, soft or rigid ureteroscopic lithotripsy, cystoscopic lithotripsy, and percutaneous nephrolithotomy. The latter includes extracorporeal vibratory wave lithotripsy.

  When capturing images using ultrasound or when pulverizing stones using vibration waves, silica gel gel is usually used as a coupling agent between skin and ultrasonic or vibration wave probe. As a result, the skin and the ultrasonic wave or vibration wave probe can be brought into close contact with each other, and the ultrasonic wave or vibration wave can be successfully introduced into the human body. Silica gel can also reduce the frictional force between the skin and the probe, so the effect of ultrasonic development and vibration wave crushed stones may be affected depending on the application position and dose of silica gel.

  Currently, silica gel used for ultrasonic waves or vibration waves is used as a coupling agent, although the problem that the contact between the ultrasonic wave or vibration wave probe and the skin is not in close contact is greatly improved. So, the main drawback is that the probe may come into direct contact with the human body as an isolation interval only with silica gel intervention, and the doctor may inadvertently injure when performing an ultrasonic or vibration wave lithotripsy procedure Body fluid and blood may flow out and mix with the silica gel solution on the probe. In this case, the doctor simply wipes the probe using only a paper towel and is used on the next patient's body in spite of hygiene concerns. From such a state, there is a risk that an infectious disease caused by the crossing of body fluids or blood between patients increases, and there is a concern about sanitary safety.

  Another drawback of using silica gel is that it is cold and uncomfortable for the patient to apply on the patient's skin. And as the probe moves, the silicone gel gradually spreads widely in the body, and after the medical procedure is completed, the patient himself often wipes with a paper towel. I can't. Furthermore, since silica gel cannot be used repeatedly, it must be wiped off with a towel after use, and the point of extremely poor convenience is a problem to be solved immediately.

  An object of the present invention is to provide a sound wave and vibration wave conducting spacer that has signal and energy transmission properties and is applied to each part of a human body.

  To achieve the above object, the present invention provides a thick piece having a first surface and a second surface opposite to the first surface, and an adhesive layer covering the second surface. And wherein the first surface is in contact with the ultrasonic probe, the adhesive layer is interdigitated with the surface to be coated, and is self-aligned. It may be an adhesive gel body.

  In the sound wave and vibration wave conductive spacer provided by the present invention, the diameter of the piece is 7 to 30 cm, and the thickness of the piece is 2 to 10 mm.

  In one embodiment of the present invention, the sound wave and vibration wave conducting spacer further includes a release paper covering the adhesive layer.

  In one embodiment of the present invention, the piece of the sound wave and vibration wave conducting spacer is a flexible object, preferably a solid hydrogel, biological fiber or other solidifiable material body, and transparent or It has a translucent aspect.

  The present invention further provides a sound wave and vibration wave conducting spacer comprising a thick piece having a first surface and a second surface facing the first surface, wherein the first surface comprises: In contact with the ultrasonic probe, the second surface is mated with the surface to be coated.

  The sound wave and vibration wave conducting spacer of the present invention comprises a thick piece and an adhesive layer, has signal and energy permeability, and is placed on the body of a sick or patient instead of a silicone gel. , Because it can effectively isolate the direct contact between the probe and the sick / patient, so that the bodily fluid and blood of the sick remain on the probe and continue to contaminate other sick, and the sick Can eliminate the potential risk of infection with body fluids and blood during the period, reduce the discomfort during the medical procedure of the sick, and the price of conventional ultrasonic silica gel is expensive and can be used repeatedly It cannot be used, and after use it must be wiped off with a large amount of tissue paper, which can improve the disadvantages such as inconvenience in use, and sound superior to conventional ultrasonic silica gel. It has a conduction effect. It also provides an option in ultrasound diagnosis and treatment that is inexpensive, can be used repeatedly on different parts of the same patient, and can be wiped without the need for complicated wiping procedures.
