Abstract: The present application provides a nose stud used for perforating and a perforating apparatus. The nose stud used for perforating comprises a needle tip and a needle bar, wherein the needle tip is connected to one end of the needle bar, and an easily bendable portion, which bends when the needle tip is subjected to a resistance force under a force applied by the needle bar, is provided at a joint. As a bendable structure is provided at the joint between the needle tip and the needle bar, the needle tip can bend relative to the needle bar after perforating the nose to avoid damaging tissues in the nasal cavity.

Abstract: A sensor includes a housing having a accommodating room, a flexible plate provided in the accommodating room and moveable to induce a medium pressure change in the accommodating room, and a pressure sensing component for sensing the pressure change. The pressure sensing component and the flexible plate are assembled and moveable together. In the sensor of the present invention, after an external signal to be sensed is transmitted to the sensor, the flexible plate moves to induce air disturbances, and then the pressure sensing component receives a pressure change induced by the air disturbances and performs signal sensing. Compared with the conventional sound sensor, the sensor of the present invention provides no opening communicating with the external environment. Therefore, the impact of foreign objects, noise and other environmental factors on the sensor can be avoided, and the signal generated by the object not to be sensed can be effectively reduced.
