Document Type and Number:
WIPO Patent Application WO/2013/176437
Kind Code:
A1
Abstract:
The present invention relates to a vacuum pressure control valve, and more particularly, to a vacuum pressure control valve allowing the amount of vacuum pressure to be adjusted in stages by adjusting the amount of inflowing air in a vacuum pressure device providing the vacuum pressure for utilization through the operation of a vacuum pump. According to the vacuum pressure control valve of the present invention, which is formed in a vacuum pressure device, no air-blocking operation is required to set a desired vacuum pressure, and the setting is completed simply through the rotation of a handle for improving convenience of use. Also, when an exact amount of vacuum pressure required for a medical treatment area is proposed, the vacuum pressure can be easily matched thereto through the rotation of the handle so as to improve the convenience of use.
