The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
A kind of combined type stethoscope diaphragm unit comprises that the encapsulate body divides 1 and diaphragm 4.
Be provided with at least one exhaust hole on circular film, breeder tube is positioned near the position in center and center of circular film, breeder tube can be avoided in the process of pressing the deformation of the circular film that the variation due to the air pressure of stethoscope inside causes, i.e. scavenging action by breeder tube, make stethoscope inside substantially keep constant air pressure, prevent the circular film transition deformation, be close to patient body in order to guarantee circular film, improve the accuracy of audio detection.
The encapsulate body divides 1 to comprise the first endless belt platform 2 and the second endless belt platform 3.Wherein, the diameter of the first endless belt platform 2 is less than the diameter of the second endless belt platform 3, between the first endless belt platform 2 and the second endless belt platform 3, the first annular sidewall 5 is set, edge at the second endless belt platform 3 is provided with the second annular sidewall 6, the second annular sidewalls 6 towards the direction extension away from the first endless belt platform 2.In addition, the external diameter edge of the first end of the first annular sidewall 5 and the first endless belt platform 2 is connected, and the internal diameter edge of the second end of the first annular sidewall 5 and the second endless belt platform 3 is connected.
The vertical height H of the first annular sidewall 5 is preferably 2.0mm greater than 1.3mm.Vertical height H than the first annular sidewall 5 in prior art is that 1.3mm compares, and vertical height H is the formation that 2.0mm is beneficial to sound collection chamber, makes the detection audio frequency more press close to the actual audio that patient's internal organs send.The impact of diaphragm deformation on hearing effect when simultaneously, it also can avoid contacting skin surface.Through experimental verification, its effect is better than far away that on market, the first annular sidewall vertical height H is the hearing effect of the diaphragm of 1.3mm.
The first endless belt platform 2 and the second endless belt platform 3 are parallel to each other and are coaxial and the first endless belt platform 2, the second endless belt platform 3, the first annular sidewall 5 and the second annular sidewall 6 are one-body molded.
The outside end face pressed on ring of the first endless belt platform 1 is provided with banded groove 7, and circular film embeds in banded groove 7.Wherein, the axial outside of the first endless belt platform 1 refers to a side of close patient body when using, banded groove radial direction is inboard to be connected with the hole of the first endless belt platform 1 radially inner side, circular film embeds in banded groove 7, and the outer surface of circular film and the first endless belt platform 1 axially outside the outer surface of end face in same level.Therefore, when using this combined type stethoscope diaphragm unit, circular film directly contacts with patient body, not only improved the goodness of fit of circular film and patient body, and and patient body between without other outer medium of deacration, audio damping significantly reduces, and has strengthened the accuracy that the user of service obtains the action message of internal organs.
A kind of combined type stethoscope diaphragm unit comprises that the encapsulate body divides 1 and diaphragm 4, and diaphragm 4 is circular film, is a kind of fiberglass resin sheet, and its diameter is 37.5mm.
The encapsulate body divides 1 to comprise the first endless belt platform 2 and the second endless belt platform 3.Wherein, the diameter of the first endless belt platform 2 is less than the diameter of the second endless belt platform 3, between the first endless belt platform 2 and the second endless belt platform 3, the first annular sidewall 5 is set, edge at the second endless belt platform 3 is provided with the second annular sidewall 6, the second annular sidewalls 6 towards the direction extension away from the first endless belt platform 2.Wherein, the external diameter edge of the first end of the first annular sidewall 5 and the first endless belt platform 2 is connected, and the internal diameter edge of the second end of the first annular sidewall 5 and the second endless belt platform 3 is connected.
The first endless belt platform 2 is 2.0mm with the vertical height sum H of circular film, thereby makes the detection audio frequency more press close to the actual audio that patient's internal organs send.The impact of diaphragm deformation on hearing effect when simultaneously, it also can avoid contacting skin surface.
The first endless belt platform 2 and the second endless belt platform 3 are parallel to each other and are coaxial and the first endless belt platform 2, the second endless belt platform 3, the first annular sidewall 5 and the second annular sidewall 6 are one-body molded.
The external diameter of circular film equates with the external diameter of the first endless belt platform 2, and circular film is pasted on the first endless belt platform 2, to guarantee that circular film contacts with the direct of patient body.
In conjunction with Fig. 1 and 6, the combined type stethoscope diaphragm unit in embodiment 1 and high-tension transmutability combined membrane of the prior art are carried out audio-frequency test.
The sound source decibel is 114dB, and the testing audio frequency is respectively 1000Hz, 500Hz, 250Hz.
The circular film specification: circular film is fiberglass resin sheet, and diameter is 38mm, and thickness is 0.2mm.
In prior art, the dimensions of circular film top encapsulate thickness d is respectively: 0.7mm, 0.55mm, 0.40mm, 0.25mm.
In embodiment 1, the dimensions of the encapsulate thickness d on circular film top is 0mm, and namely there is not encapsulate in circular film top.
Audio-frequency test the results are shown in Table 1, and table 1 is as follows:
Table 1
The encapsulate thickness d on the audio value after the decay and circular film top is roughly linear as shown in Table 1, the encapsulate thickness d on circular film top is less, audio value after decay is larger, be that audio damping is less, until the encapsulate thickness d on circular film top is 0mm, when namely there was not encapsulate in circular film top, the audio value after decay was maximum, be that audio damping is minimum, this moment, the acoustic effect was best.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should not consist of any restriction of the present invention.As long as within any improvement that the present invention is done or modification all belong to the protection domain that claim of the present invention advocates.
