Abstract
To provide ultrasonic treatment of animals, ultrasonic waves in a frequency range of between 15 kilohertz and 100 kilohertz are applied to water in a tub with a power density between 0.1 and 5 watts per square centimeter. The equipment is able to apply ultrasonic waves with at least two power densities in the vicinity of the portion of the animal with one of said power densities being more than 15 watts per square meter for sterilizing the water before the patient enters the tub and the other being less than 15 watts per square meter.
Claims24
A method of treating an animal in a working fluid contained within wall means comprising the steps of:
- transmitting ultrasonic vibrations at a power density in excess of 15 watts per square centimeter through the working fluid during a first time period in which no portion of the animal is immersed in said working fluid, whereby sterilization is provided to said working fluid;
- immersing a body portion of the animal into the working fluid during a second time period different than the first time period with the portion being in acoustic contact with the fluid;
- and
- applying ultrasonic vibrations through the working fluid to the portion of the body at a frequency in the range of 15 kilohertz to 100 kilohertz and a power density sufficiently below 15 watts per square centimeter to avoid discomfort to the animal during the second time period.

A method of treating an animal comprising the steps of:
- immersing a body portion of the animal into a working fluid with the portion being in acoustic contact with the fluid;
- and
- applying ultrasonic waves through the working fluid to the portion of the body at a frequency in the range of 15 kilohertz to 100 kilohertz and a power density in the range of 0.1 to 5 watts per square centimeter through the working fluid for a time less than 15 minutes and at a power and frequency that does not cause transient cavitation.
A method of treating an animal comprising the steps of:
- immersing a body portion of the animal into a working fluid with the portion being in acoustic contact with the fluid;
- applying ultrasonic waves through the working fluid to the portion of the body at a predetermined frequency in the frequency range of 15 kilohertz to 100 kilohertz and a power density sufficiently below 15 watts per square centimeter to avoid discomfort to the animal;
- and
- modulating the predetermined frequency with a sweep frequency across a predetermined sweep frequency band.

Apparatus for ultrasonic treatment of an animal comprising:
- container means adapted to contain a working fluid in which at least a portion of an animal may be immersed for treatment by ultrasonic waves;
- and
- means for applying ultrasonic waves through the working fluid within the container means in two selected ranges differing from each other at least in corresponding ones of two different time periods, wherein one of said selected ranges is in a power density range of less than 15 watts per square centimeter and frequency range between 15 kilohertz and 100 kilohertz and the other range is in a power density range greater than 15 watts per square centimeter, said other time period being sufficient to destroy microbes.
Apparatus for ultrasonic treatment of an animal comprising:
- container means adapted to contain a working fluid in which at least a portion of an animal may be immersed for treatment by ultrasonic waves;
- and
- means for applying ultrasonic waves in a frequency range of between 15 kilohertz and 100 kilohertz through the working fluid within the container with a power density of the ultrasonic waves in the working fluid that is in contact with the animal being between 0.1 and 5 watts per square centimeter and a power and frequency that does not cause transient cavitation.
Apparatus for ultrasonic treatment of an animal comprising:
- container means adapted to contain a working fluid in which at least a portion of an animal may be immersed for treatment by ultrasonic waves;
- means for applying ultrasonic waves in a first frequency in a first frequency range of between 15 kilohertz and 100 kilohertz through the working fluid within the container with a power density which is capable of beneficial effects without being harmful to the animal;
- and
- means for modulating the first frequency of the ultrasonic waves with a second sweep frequency across a second frequency band centered on the first frequency.

A method of treating animals comprising the steps of:
- immersing a body portion of the animal into a working fluid with the portion having a wound in it and being in acoustic contact with the fluid for a number of times between once every two days and four times a day and for a time period selected to avoid increasing inflammation and retarding healing wherein the bather is cleaned while wound healing is aided;
- and
- applying ultrasonic waves through the working fluid to the portion of the body each time at a frequency in the range of 15 kilohertz to 100 kilohertz and a power density in the range of 0.1 to 5 watts per square centimeter through the working fluid for a time less than 15 minutes and at a power and frequency that does not cause transient cavitation.
