Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to an ear tip for a stethoscope.

[0002]

[Prior art]

  A stethoscope is an essential medical device for doctors, and a stethoscope ear worn on the ear during auscultation. A chip as shown in FIGS. 1 to 3 is generally used.   This stethoscope ear tip includes a tubular ear tip body 1 with open ends, A screw plug 20 fitted into one end thereof, and formed inside the screw plug 20. The distal end of the U-shaped sound transmission tube of the stethoscope is screwed into the thread groove.   One end of the ear tip body 1 is a connecting pipe 14 having an appropriate length. 4, an engagement hole 15 having substantially the same shape as the outer shape of the screw plug 20 is formed. A screw plug 20 is fitted to the screw 5.

[0003]   At the other end of the ear tip body 1, a spherical ear insertion portion 10 is connected to the connecting pipe 14. It is integrally formed, and inside the ear insertion part 10 has a shape similar to the outer shape of the ear insertion part 10, A through hole 16 that connects the engagement hole 15 and the other end side of the ear tip body 1 is formed. There is.   Then, when the ear insertion unit 10 is inserted into the ear, the sound obtained by the sound collecting unit of the stethoscope becomes It passes through the transmission pipe, the screw plug 20 and the through hole 16 to reach the ear.

[0004]

[Problems to be solved by the device]

  However, the conventional ear tip body 1 is deformed to penetrate the sound passage path. Most of them are made of hard rubber so that the through holes 16 do not close, I often feel pain inside my ears when I wear it.   The purpose of the present invention is to be flexible and fit the shape of the ear easily, Providing stethoscope ear tips that are comfortable to wear without causing pain Especially.

[0005]

[Means for Solving the Problems]

  The stethoscope ear tip of the present invention is composed of a tubular ear tip body with open ends. , A screw plug into which the end of the sound transmission tube is screwed, and is connected to one end of the ear tip body. A connecting pipe is formed, and the screw plug is fitted inside the connecting pipe, Inside the peripheral wall of the ear insertion part of the ear tip body, the tip body is made of soft rubber. , An annular cavity is formed along the circumferential direction, and liquid or air is stored in the cavity. Has been injected.

[0006]   The material of the eartip body is soft rubber, and liquid or air is put in the cavity of the ear insertion part. Due to the structure in which is injected, the feeling of touch becomes soft.   Due to the elasticity of soft rubber and the flexibility of liquid or air, the peripheral wall of the ear insertion part should be inserted into the ear. When fitted, it fits the shape of the ear canal and can strongly press a part of the ear canal. In addition, the strength of the peripheral wall is secured and the sound transmission path is prevented from being completely closed. Gu

[Embodiment of device]

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. Note that the figure In the figure, the same parts as those in the conventional example are designated by the same reference numerals.   As shown in FIGS. 4 to 6, the stethoscope ear tip has a tubular shape with both ends open. The ear tip body 1 and the screw plug 20 are provided.   A screw groove is formed on the inner circumference of the screw plug 20, and the end of a sound transmission pipe (not shown) is inserted in the screw groove. The ends are screwed together. As a result, the stethoscope ear tips and the The parts are connected.

[0008]   The ear tip body 1 is made of soft rubber and has a connecting pipe 14 formed at one end thereof. At the same time, the substantially spherical ear insertion portion 10 is formed at the other end.   As shown in FIG. 4 and FIG. 5, the inside of the connecting pipe 14 corresponds to the outer shape of the screw plug 20. The engagement hole 15 having a curved shape is formed, and the screw plug 20 is engaged with the engagement hole 15.   A through hole 12 having a substantially uniform diameter is formed along the central axis of the ear insertion portion 10. The engaging hole 15 and the other end side of the ear tip body 1 are communicated with each other by the through hole 12. ing. Therefore, the sound reaching the screw plug 20 from the sound transmission tube passes through the through hole 12 and reaches the ear. It will be transmitted to the other end of the insertion portion 10.

[0009]   The peripheral wall 11 of the ear insertion portion 10 surrounding the through hole 12 has an annular space along the circumferential direction. The sinus 13 is formed.   This cavity 13 is formed during the process of molding the ear tip body 1 and A liquid or air that is harmless to the body is injected into the cavity 13. For this reason, The wall 11 has a certain strength or more while maintaining a soft touch and flexibility, It does not deform so much that the hole 12 is completely closed.

[0010]

[Effect of device]

  According to the present invention, the material of the ear tip body is made of soft rubber, and the inner wall of the ear insertion part is Since liquid or air is injected into the part, the feel is soft and rich in flexibility, and moreover, When used, the peripheral wall of the ear insertion part fits the shape of the ear cavity properly, which is why It is comfortable to wear and does not cause discomfort even after long-term use.
