Abstract
The utility model relates to a stethoscope comprising earplugs, a sounding rod, sounding hosts and a stethoscope head, wherein the stethoscope head comprises a membrane, a sound collecting shade, a sealing sheet and a connection head; the membrane is sheathed at one side of the sound collecting shade, and is fixedly connected by the sealing sheet; the connection head is arranged at the other side of the sound collecting shade; a sounding channel is arranged on the sound collecting shade; a sound collecting chamber is arranged in the connection head; and the sounding channel is communicated with the sound collecting chamber. The two sounding hosts are separated to close the sounding channel alone respectively for communicating the two earplugs, so the sounding clearing and flexibility is improved. One end of each sounding host accessed to the stethoscope head is fixedly connected so that interference generated by friction at the intersection of the rounding hosts is avoided. The vibration of the membrane in the stethoscope head enables gas in the stethoscope head to generate vibration, and the vibration is obvious and uniform through the sounding channel and the sound collecting chamber to be respectively transmitted into the sounding hosts, so the sounding is clear, and the flexibility is high when in treating use.
Description
Technical field
This utility model relates to a kind of stethoscope, belongs to medical instruments field.
Background technology
At present domestic stethoscope great majority commonly used are the stethoscope of old-fashioned single cavity member of adopting the fifties design, because the branch of its transaudient road from the auscultation head to transaudient bar about not having, so acoustic is clear inadequately; Isolating two sebific ducts connect auscultation head and transaudient bar though the stethoscope that now also has on the market adopts fully, friction generation noise has still influenced acoustic but because two sebific ducts cross mutually at the auscultation head, and the structure of auscultation head is comparatively single, the sound of gas in the auscultation head being stirred by vibration membrane directly passes in the sebific duct, noise is more and because extraneous interference, making the doctor can't carry out pathology to the sound of hearing by stethoscope judges, might mistaken diagnosis appear or mistake is examined, cause malpractice, increase the misery of patient body and loss economically.
The utility model content
It is clear, highly sensitive and make the doctor can judge a kind of auscultation with stethoscope device of conditions of patients accurately that technical problem to be solved in the utility model provides a kind of acoustic.
For addressing the above problem, this utility model by the following technical solutions:
A kind of stethoscope, comprise earplug, transaudient bar, transaudient sebific duct and auscultation head, it is characterized in that: described auscultation head comprises shake film, sound collection cover, diaphragm seal and union joint, described shake Membrane cover is contained in a side of sound collection cover, fixedly connected with diaphragm seal, described union joint is provided with the opposite side of sound collection cover, and described sound collection cover is provided with transaudient passage, be provided with collection sound chamber in the described union joint, described transaudient passage is communicated with collection sound chamber.
Below be further improvement of these options:
Described transaudient passage is arranged on the center of sound collection cover.
Described sound collection cover cross section is a C shape, and described shake Membrane cover is contained in a side of the sound collection cover opening of C shape.
Described diaphragm seal is to be that the successive closed hoop of U-shaped constitutes by the cross section.
Described union joint is provided with connector.
One end of described transaudient sebific duct connects transaudient bar, and the other end of transaudient sebific duct connects the auscultation joint, and described auscultation joint is threaded with connector.
This utility model compared with prior art, have following characteristics: be divided into two separate airtight passages by two transaudient sebific ducts, it is communicated with two earplugs of effect respectively, acoustic definition and sensitivity have been improved, insert the fixedly connected setting of the first end of auscultation and can effectively avoid the fricative interference of sebific duct intersection, the vibrations of shake film make that gas produces vibration in the auscultation head in the auscultation head, make that by transaudient passage and collection sound chamber vibrations are more obvious, unified, be transferred in the transaudient sebific duct then respectively, make that acoustic is more clear when going to a doctor use, sensitivity is higher.
The utility model is described in further detail below in conjunction with drawings and Examples:
