Abstract

PURPOSE: Provided is a combiner for ultrasonic wash and steam sterilization, which performs both functions by using a single chamber in a non-stop mode to reduce the problem of the user's exposure to pathogenic bacteria and to decrease the working time. CONSTITUTION: The combiner for ultrasonic wash and steam sterilization is used for washing contaminated instruments used in a hospital by using ultrasonic waves. The combiner for ultrasonic wash and steam sterilization is operated along the sequence of water supply; washing; evacuation; rinsing; vacuum-heating; sterilizing; evacuation-drying. Alternatively, the combiner for ultrasonic wash and steam sterilization is operated along the sequence of water supply; washing; evacuation; rinsing; heating; sterilizing; evacuation.

Description

Combiner for Ultrasonic Wash and Steam Sterilization

The present invention relates to an ultrasonic washing autoclave for cleaning and sterilizing bacteria adhered to instruments used in bottles, clinics and the like, and instruments such as laboratory substrates.

Conventionally, high pressure steam sterilizers have a problem in that they are inconvenient to wash one by one and various pathogenic bacteria are not used as a washing function in water supply → heating → sterilization → exhaust → drying process.

In addition, there is a financial burden to separately purchase a washing machine and a high-pressure steam sterilizer in bottles and clinics, and a space burden to be installed separately in a clinics-level hospital that lacks space.

In order to improve the above problems, the present invention uses a single chamber to perform ultrasonic cleaning and autoclaving for two purposes: water supply → washing → exhaust → rinse → vacuum → heating → sterilization → exhaust → drying process. Space saving and cleaning due to the use of the chamber to sterilization is characterized in that it is done at once.

⑭ Jacket (where water is generated to produce saturated steam)

Vent Air Vent (device to remove air from the chamber)

The configuration of the present invention for achieving the above object is as follows. That is, in the water supply process of the present invention, the water pump (8) and the solenoid valve (4), the solenoid valve (5) in the chamber 13 and the jacket Water is supplied to 14. In the cleaning process, the ultrasonic vibrator 11 in the chamber 13 vibrates to generate a cavitation phenomenon due to a change in sound pressure, thereby removing and removing foreign substances. At this time, the heating element 12 in the jacket 14 cuts off water to generate saturated steam. . In the exhaust process, the water in the chamber is discharged by the solenoid valve (6). In the rinsing process, water enters the chamber 13 from the water pump 8 and the solenoid valve 4 to rinse the contents and is discharged by the solenoid valve 6 after the rinsing is finished. In the vacuum process, air in the chamber 13 is removed by a vacuum pump (9) and a solenoid valve (2). In the heating process, saturated steam stored in the jacket 14 is introduced to the sterilization temperature (121 to 135 degrees) set by the solenoid valve 3 to the chamber 13. In the sterilization process, the set sterilization temperature (121 to 135 degrees) in the chamber 13 is maintained by the solenoid valve 3. In the exhaust process, saturated steam in the chamber is discharged by the solenoid valve (6). In the drying process, residual steam in the chamber 13 is removed by a vacuum pump (9) and a solenoid valve (2) for a predetermined time and fresh air is introduced by the solenoid valve (1). This process is repeated until the set drying time.

As described above, the ultrasonic washing autoclave of the present invention can obtain two effects of ultrasonic washing and autoclaving by using one chamber, and the process from washing to sterilization can be performed at one time. The risk of exposure and the time spent can be reduced. In addition, it can reduce the spatial burden of installing a separate washing machine and autoclave in a hospital-level hospital lacking space.
