Description

Technical Field

[0001] The utility model relates to the field of medical technology, and specifically relates to a medical ceramic feedthrough component. Background Technique

[0002] A vacuum feedthrough component is a component that can allow gas or substances to be transmitted between a vacuum system and external equipment. It usually consists of two interfaces and a cavity, and the internal cavity is connected to the two interfaces. The main function of the vacuum feedthrough component is to connect two vacuum systems or connect a vacuum system and an external equipment to achieve the transmission of gas or substances.

[0003] Ceramic feedthrough components are often used in medical equipment. For example, the feedthrough component and vacuum system with the publication number CN217239385U record that insulating colloid is filled in the accommodating space to achieve insulation, and at the same time, the internal space of the flange is sealed to avoid affecting the normal operation of the conductive component. In this way, the manufacturing process is simple, the production efficiency is good, the production cost is low, and the sealing effect is good. The accommodating space is filled with insulating colloid to achieve a vacuum effect. However, when the insulating colloid is filled, some air will be filled into the internal of the accommodating space together. Therefore, when the feedthrough component transmits information, it will be affected by the air filled in the accommodating cavity, thus affecting the information transmission. Therefore, we propose a medical ceramic feedthrough component. Content of the Utility Model
