Pneumatic device of medical air-closed brake system

Abstract

The invention relates to a pneumatic device of a medical air-closed brake system, which comprises a base and is characterized in that a gas transmission channel is distributed in the base, and one end of the gas transmission channel is provided with a pressing plate assembly. Meanwhile, the pressing plate assembly is provided with an air vent communicated with the gas transmission channel, and the lower side of the pressing plate assembly is connected with the base through a fastening assembly. The pressing plate assembly is provided with a gas film assembly, a gas accommodating cavity is formed between the inner wall of the gas film assembly and the pressing plate assembly, and the other end of the gas transmission channel is provided with a jointing assembly. Thus, force for brake operation can be generated by only injecting less gas due to the existence of the gas accommodating cavity, and the safety performance of timely and effective braking is achieved. In addition, the pneumatic device is simple in structure, low in production cost and capable of being popularized and applied to the medical air-closed brake system corresponding to the pneumatic device.

Description

technical field [0001] The invention relates to a pneumatic device, in particular to a medical air-holding brake system pneumatic device. Background technique [0002] The medical pendant is an indispensable air supply medical equipment for the modern operating room of the hospital. It is mainly used for the terminal transfer of oxygen supply, suction, compressed air, nitrogen and other medical gases in the operating room. It controls the lifting of the equipment platform by a motor, which is safe and reliable. Its balanced design ensures the level of the equipment platform and ensures the safety of the equipment. At the same time, the drive of the motor ensures that the equipment operates quickly and effectively. [0003] The operation and use of the pendant is inseparable from the necessary positioning brake system, and the pneumatic mechanism is an important component of the medical air-tight brake, which provides sufficient power support for the entire brake system.

Problems solved by technology

However, existing brake assemblies including pneumatic devices cannot meet the requirements of air-tight brakes.

If the existing brake components are used, it is easy to have the defect that the lock cannot be achieved. At the same time, if the existing brake components are only modified, the cost of modification and application is also high.
