Detachable type stethoscopy head

Abstract

The present invention belongs to a medical apparatus, in the concrete, it relates to a removable type stethoscopic head. According to the technical scheme provided by said invention on the auditory head at least an auditory cavity is set, in the opening position of said auditory cavity an auditory membrane is set, in the auditory head interior the head portion of a turntable auditory bar is set, in the head portion of said auditory bar an axial channel and an auditory bar channel perpendicular ot said axial channel are set, said axial channel is communicated with said auditory bar channel, in the auditory head interior and in the bottom portion of said auditory cavity an auditory head channel is set. It is characterized by that one end of auditory bar channel is formed into a large end channel, its another end is formed into a small end channel, in the combined position of said large end channel and small end channel an auditory bar end face is formed; in large end channel interior a positioning component with spherical surface is placed, between the positioning component with spherical surface and end face of auditory bar is placed a spring, and in one end of auditory head channel close to auditory cavity an inlet is set, and between the inlet and auditory head channel an auditory head end face is formed.

Description

technical field [0001] The invention belongs to a medical device, in particular to a detachable stethoscope head. Background technique [0002] A stethoscope is a device used for diagnosing changes in the sound of organs such as the human heart and lungs. The stethoscope is the main part of the stethoscope. It is generally composed of the listening head and the listening rod. There is a listening cavity on the listening head. There is a channel for transmitting sound between the listening cavity and the listening rod. The opening of the listening cavity The part has an auditory membrane. Since different auscultation heads are needed to auscultate different organs, two or three listening cavities of different shapes and sizes are often set on one auscultation head, and respective channels are set on each listening cavity. When which listening chamber needs to be used, the listening rod is rotated so that the passage on the listening rod is communicated with the passage of t...

Problems solved by technology

The disadvantage of this structure is: the sleeve structure is complex, in order to enable the sleeve to be smoothly pressed back into the channel on the listening rod, the surface of the opening of the sleeve must be made into a spherical surface, which makes processing and assembly very difficult; At the same time, due to the relatively high processing precision requirements, once the precision is insufficient, the phenomenon of poor rotation of the listening rod or easy pulling out of the listening rod may easily occur; in addition, if the product fails and is repaired, the parts will be scrapped; therefore, the manufacturing cost is relatively high
