Description

[Detailed description of the invention] The present invention relates to an ultrasonic transport tube characterized by the following.

To explain the embodiment of the present invention shown in the drawings, the material 4 forms a thin tube 1 which is a gas phase film made of foamed synthetic resin which is an aggregate of air bubbles, and the ultrasonic transport medium is a liquid (solution or chemical solution) or a metal wire, etc. A medical catheter can be made using this solid material. The material 4 between the conveyance medium and the inner circumference 2 and outer circumference 3 of the tube 1 is in a gas phase and has an apparent specific gravity significantly smaller than the apparent specific gravity of the ultrasonic conveyance medium inside the interpipe 1. In addition, what is shown by 5 in the figure is countless microbubbles within the material 4.

Therefore, the above-mentioned liquid-flowable tube 1 is used as a medical catheter, inserted into a blood vessel, and the distal end reaches the affected area.Medicinal liquid is allowed to reach the affected area from outside the human body through the interstitial tube 1, and at the same time, Ultrasonic vibrations are applied to the medicinal solution in the tube 1. In this way, the sound waves are reflected and transmitted through the medicinal solution in the intervening tube 1 through the bent tube 1, reach the affected area, and vibrate the affected area. Due to this vibration, the medicinal solution acts on the affected area and can treat the affected area.

In addition to the above-mentioned chemical solution, the ultrasonic transport medium may be a solution such as Ringer's solution, or a metal medium may be used when only ultrasonic transport is desired. The ultrasonic carrier medium at the tip of tube 1 is brought into contact with bile duct stones and urinary tract stones, and powerful B-sonic vibrations are applied only to the target stone from the outside.This is extremely safe as there is no ultrasonic leakage from the middle of tube 1. can be crushed. Moreover, by simultaneously injecting a stone-dissolving drug into the tube 1, the drug-dissolving efficacy is significantly increased due to the synergistic effect with the ultrasonic vibration.

For ultrasonic diagnosis, the tube 1 is inserted deep into the body and ultrasonic pulses having an incident angle are emitted from the outer tube opening, and can be used as an echo diagnostic probe having a sound source deep in the body. Industrially, woodwinds can be used to transmit physical ultrasonic vibration energy over long distances, so they can be used not only for communications, but also for applications such as in narrow bends, underwater, or near explosives (no electrical system involved), without being subject to location constraints. The scope of use can be expanded.

Conventionally, the material of liquid-flowable tubes such as medical catheters or vinyl blood transport tubes has an apparent specific gravity that is approximately the same as or greater than the internal fluid of the intervening tube, so the internal fluid can be used as a medium. When an ultrasonic wave is emitted, the sound wave propagates from the inner wall of the tube to the outer wall to the water or liquid outside the intercanal, and it has been extremely difficult medically or industrially to transmit the ultrasonic wave from a remote location to the target affected area.The present invention was made in view of the above-mentioned defects, and since the present invention is an ultrasonic conveying tube characterized in that the ultrasonic conveying medium is coated with a vapor phase coating as described above, the above-mentioned vapor phase coated tube 1. When ultrasonic vibrations are applied to the internal ultrasonic transport medium from the outside, there is no risk that the sound waves will propagate to the outside of the tube through the gas phase coating between the inner and outer walls of the tube, and Ultrasonic refraction and transport to a target object in a diseased area or liquid can be carried out extremely easily and efficiently without being affected by ultrasound waves from the surrounding area, thereby significantly improving the safety and efficiency of medical or industrial methods. There are benefits to be gained.
