Abstract:
A patient table includes a table body configured for bearing a patient, a connecting rod structure configured for supporting the table body, and a spring structure. The connecting rod structure is operable such that the table body may perform a lifting motion between a high position and a low position. Both ends of the spring structure are fixed. At least a first end of the spring structure is hinged to the connecting rod structure. The spring structure may be used for driving the lifting motion of the connecting rod structure and/or bearing the table body. The patient table may be used for nuclear magnetic resonance imaging equipment.

Abstract:
Disclosed is an earphone including: an earplug that is a rigid pipe; a soft cap that is an elastic sheath, wherein the soft cap includes a body and a top end, the body being in the form of a hole, the top end covering one end of the body, an inner wall of the body matching an outer wall of the earplug, and one end of the earplug being positioned in the body. The earphone not only may reduce noise but also enables useful information to be heard, as well as ensuring that foreign matter cannot enter the earphone and the soft cap may be detachably fixed to the earplug so as to guarantee sanitary use.
