Abstract
The utility model relates to a stethoscope head, which comprises a vibrating diaphragm, a sound concentrating hood, a seal gasket and a connector. The vibrating diaphragm is mounted on one side of the sound concentrating hood and fixedly connected with the seal gasket, the connector is arranged on the other side of the sound concentrating hood, and a sound transmitting passage is arranged on the sound concentrating hood. Due to the design of the vibrating diaphragm, pickup flexibility, sound strength, sound transmission resolution and flexibility are all increased. Air in the stethoscope head generates vibration along with vibration of the vibrating diaphragm in the stethoscope head, and the vibration is enhanced and more uniform through the sound transmitting passage and then transmitted to a sound transmitting rubber hose, so that sound transmission resolution and flexibility are higher when the stethoscope head is used for diagnosis.
Description
Technical field
This utility model relates to a kind of auscultation head, is the important composition parts on the stethoscope, belongs to medical instruments field.
Background technology
The stethoscope type has single electronic stethoscope with stethoscope, double-purpose stethoscope, triple change stethoscope, vertical stethoscope, universal stethoscope and up-to-date appearance present at present, no matter be which kind of stethoscope, all be partly to carry out work by pickup part, conduction portion and audition, what wherein determine the stethoscope quality is the pickup part, also is the auscultation head that we are commonly called as.
In general, the big more audio that regains more of auscultation head is really good more, but because the structure of human body, human body surface has radian, if chest piece is excessive, can not contact with human body fully, and sound equipment not only can not pick up well, also can rush down and spill from the space, therefore, the size of auscultation head should be based on clinical needs, so the auscultation head has certain size regulation, the diameter of auscultation head nearly all is unified between the 45-50 millimeter, the special diameter as the department of pediatrics chest piece is generally 30 millimeters, and neonate is 18 millimeters, for better pickup, need to improve the structure of auscultation head, make its shake film can better pickup.
The utility model content
It is clear, highly sensitive and make the doctor can judge a kind of auscultation head 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 auscultation head, it is characterized in that: described auscultation head comprises shake film, sound collection cover, diaphragm seal and union joint, and described shake Membrane cover is contained in a side of sound collection cover, and is 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.
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.
This utility model compared with prior art, have following characteristics: by the sensitivity of design pickup of shake film and the intensity of sound, acoustic definition and sensitivity have been improved, the vibrations of shake film make that gas produces vibration in the auscultation head in the auscultation head, make vibrations obvious more, unified by transaudient passage, be transferred to then in the transaudient sebific duct, make that acoustic is more clear, sensitivity is higher when going to a doctor use.
The utility model is described in further detail below in conjunction with drawings and Examples:
