Embodiment 1

[0061] Example 1: Combining figure 1 , figure 2 , image 3 , Figure 4 It can be seen that

[0062] The composite diaphragm is composed of a circular diaphragm 11 and a fixing piece 12 . The fixing part 11 has an integral structure, including a large ring 122 , a small ring 121 and a connecting portion 123 . Wherein the diameter of the large ring 122 is greater than the diameter of the small ring 121, the large ring 122 is located below the connection portion 123, the small ring 121 is located above the connection portion 123, and the small ring 121 is radially provided with an annular groove 124, The outer edge of the circular diaphragm 11 is located in the ring groove 124 .

[0063] The rest are the same as above,

[0064] In combination with embodiment 1 and figure 1 , figure 2 It can be seen that the connecting portion 123 is a circular ring 125 provided with a shoulder 126;

[0065] In combination with embodiment 1 and image 3 , Figure 4 It can be seen that...

Embodiment 2

[0067] Example 2: Combining Image 6 , Figure 7 , Figure 21 To further illustrate the present invention

[0068] The listening head 2 includes a listening head body 21 and a cylinder 22. The listening head body 21 includes two parts: the body A for listening to high-frequency sounds and the body B for listening to mid-high audio. The cylinder 22 is located on the middle-high audio body B of the listening head body 21. The body 22 is integrated with the listening head body 21, and an axial ring groove 222 and a sound collecting surface 223 are arranged on the cylindrical end surface 221, and a sound guiding hole 224 and a fixing hole 225 are arranged on the sound collecting surface 223. The outer side 220 of the cylinder is radially provided with an annular groove 227 .

[0069] The middle and high frequency audio body B is located above the cavity 5, and the low-frequency audio body A is located below the cavity 5. The low-frequency audio body A is provided with a sound c...

Embodiment 3

[0073] Embodiment 3: combine below figure 1 , figure 2 , image 3 , Figure 4 , Figure 12 , Figure 14 , Figure 21 To further illustrate the present invention

[0074] The matching structure of the listening head and the composite diaphragm, including the listening head 2, the diaphragm 1 and the C-shaped sealing ring 4;

[0075] The diaphragm 1 is composed of a circular diaphragm 11 and a fixing part 12. The fixing part 12 includes three parts: a large ring 121, a small ring 122 and a connecting part 123. The large ring 122 is located below the connecting part 123, and the small ring 121 Located above the connecting portion 123, the small ring 121 is provided with a ring groove 124 in the radial direction, wherein the diameter of the large ring 122 is different from that of the small ring 121, the diameter of the large ring 122 is large, and the outer edge of the circular diaphragm 11 Located in the ring groove 124.

[0076] The listening head 2 includes a listenin...

Abstract

The invention relates to a medical instrument accessory, in particular to a stethophone accessory. The invention discloses a combined membrane which comprises a round membrane and a fixer. The fixer comprises three parts including a big ring, a small ring and a connecting part, wherein the big ring is arranged below the connecting part, the small ring is arranged above the connecting part and radially provided with a ring slot, and the outer edge of the round membrane is positioned in the ring slot. The invention also provides a stethoscope head which comprises a stethoscope head body and a cylinder, wherein the cylinder and the stethoscope head body are integrated into a whole, the end surface of the cylinder is provided with an axial ring slot and a sound collecting surface; and a soundguide hole and a fixing hole are arranged on the sound collecting surface. The membrane has the advantages of good restoration and accurate positioning; the stethoscope head is easy to install and hasstrong tightness; and users can acutely acquire a matching structure of multitone only by changing force applied on the stethoscope head body.

Description

technical field [0001] The invention relates to a medical device accessory, especially a stethoscope accessory, specifically a stethoscope diaphragm, an earpiece using the diaphragm, and a matching structure of the diaphragm and the earpiece. Background technique [0002] The stethoscope is an important tool for medical staff to perform medical work. With the help of the stethoscope's loudspeaker function, the user can understand the activity of the internal organs of the patient. The stethoscope collects and amplifies the working sound of the patient's internal organs through the listening head, and then transmits it to the user's ear through the listening tube and earplugs. [0003] To judge the activity of the internal organs of the patient, the user needs to touch the vibrating membrane of the stethoscope to the body of the patient. Chinese Patent No. 200520122864.7 discloses a stethoscope diaphragm. In use, the diaphragm completely relies on the resilience of the diaphr...
