experiment example

[0078] The cleaning tank 16 adopts an internal volume of 500 x 300 x 140 mm in depth, and injects 15 liters of water therein. Ultrasonic transducers 14 are provided with 4×2 25 kHz transducers on the bottom of the cleaning tank, and 3 50 kHz transducers on both sides, totaling 14 ultrasonic transducers 14 . That is to say, ultrasonic cleaning is performed by shear action accompanied by traveling wave impact interference from three aspects of independent vibration causing radial dispersion, horizontal and vertical interference, and phase angle consideration.

[0079] Air containing ozone is fed through the communication path 42 of the ultrasonic transducer 14 , and microbubbles excited by ultrasonic waves are sent into the tank from the discharge port 40 .

[0080] As non-pathogenic microorganisms, E. coli was selected from JM109 strain, and budding yeast was obtained from FY24 strain of S288C strain; as sterilization operations, four methods of ozone, ozone and ultrasonic, cop...

Abstract

An ultrasonic cleaning method and an ultrasonic cleaning device are provided, which are capable of performing simultaneously cleaning and sterilization of medical appliances or the like, and which can also be used for washing hands for disinfection without any special waste water treatment. The ultrasonic cleaning method for cleaning an object to be cleaned by using an ultrasonic wave includes the steps of putting cleaning fluid and the object to be cleaned in a cleaning tank (16), and applying ultrasonic vibrations to the cleaning fluid from an ultrasonic vibration member disposed in the cleaning tank (16) while ejecting air containing ozone into the cleaning fluid. The vibration portion has a communicating conduit 40 that opens at the surface thereof, and air containing ozone is discharged into the cleaning fluid from the communicating conduit. A silver electrode is disposed in the cleaning fluid, and electrolytic sterilization by silver ions is performed for the object to be cleaned adding to sterilization by ozone.

Description

technical field [0001] The invention relates to a method and a device for ultrasonic cleaning by applying ultrasonic vibration to cleaning liquid in a cleaning tank. Background technique [0002] In the past, in institutions such as hospitals, in cleaning and sterilizing medical instruments such as scissors and biological forceps used in surgery and treatment, 1) using hot water or enzyme treatment to remove blood, etc. (hereinafter referred to as "pre-cleaning"), (2) Ultrasonic cleaning using cleaning agents, (3) Sterilization by high-pressure steam at 135° using an autoclave or gas sterilization with ethylene oxide gas, and sterilizing by immersing in a 2% glutaraldehyde aqueous solution. Bacteria etc. [0003] In addition, white clothes should be sterilized with high-pressure steam after they are stained by normal washing. [0004] There are many devices currently on the market that are cleaned by ultrasonic waves in the above (2), but the objects that can be cleaned by...
