Abstract
The invention relates to a medical instrument, especially to a stethoscope, and in particular to a resetting means after the displacement of a diaphragm. A resetting means after the displacement of adiaphragm for a stethoscope, comprises the diaphragm, a sealing lining and a tin body of the stethoscope, wherein, the diaphragm and the tin body of the stethoscope are fixed by the sealing lining hemetically, a sounder resonator is formed between the diaphragm and the similar bowl-shaped sounder collecting surface arranged on the tin body of the stethoscope, a ring-shaped spacing step is arrangedat an bowl opening of the bowl-shaped sounder collecting surface, the diaphragm is placed in the ring-shaped spacing step, and a spring, of which one end is contacted with the diaphragm and the otherend is fixed on the sounder collecting surface, is arranged in the sounder resonator. The invention has the advantages of strong durability, accurate positioning, and accurate acquirement of the movable information of the internal organs of patents.
Description
Technical field
The present invention relates to a kind of fitting of medical apparatus, refer to a kind of stethoscopic accessory that is used for especially.
Background technology
Stethoscope is the important tool that the medical and nursing work personnel carry out curative activity, and by stethoscopic sound amplification function, user can be recognized the situation of those internal organs of the patient that sees a doctor.Stethoscope is to collect by the operational sound that can will the person's of seeing a doctor internal organs to amplify, and is passed to the ear of user again via listening tube, earplug.
Do not changing the contact position of stethoscope at present with the person of seeing a doctor, the medical and nursing work personnel operation once can be listened to the stethoscope of double-tone, mostly be to act on the person of seeing a doctor by stethoscope is granted external force, make the person's of seeing a doctor counteracting force in vibrating diaphragm, cause the vibrating diaphragm distortion, to arrive the volume that changes collection sound chamber, reach the purpose of listening to different audio frequency.But the recovery of vibrating diaphragm deformation is the restoring force that relies on vibrating diaphragm self fully, because the fatigue of diaphragm material usually causes vibrating diaphragm not restore, cause the location inaccurate behind the life-time service, can't listen to the person's of seeing a doctor visceral motility audio frequency exactly, and the service life of vibrating diaphragm is shorter.China Patent No. 200520122864.7 disclosed a kind of these type of films.
Summary of the invention
Main purpose of the present invention is, provides a kind of only by the vibrating diaphragm displacement, not by vibrating diaphragm deformation, and accurate positioning, can accurately obtain the different audio frequency of the person's of seeing a doctor internal organs, and can vibrating diaphragm long a kind of displacement of diaphragm for stethoscope restoring means in service life.
The object of the present invention is achieved like this:
A kind of resetting means after displacement of diaphragm for stethoscope, involving vibrations film, seal ring set and stethoscope tin body; Described seal ring set is with described vibrating diaphragm and described stethoscope tin body sealing and fixing, described vibrating diaphragm and be located at and form collection sound chamber between the similar bowl-shape sound collecting surface on the described stethoscope tin body is provided with the ring-type limited step at the rim of a bowl place of described bowl-shape sound collecting surface; Described vibrating diaphragm places in the described ring-type limited step; Be provided with spring at described collection sound intracavity, the one end contacts with described vibrating diaphragm, and the other end is fixed on the described sound collecting surface.
Further; The bowl bottom of described sound collecting surface is provided with and is used for fixing elastomeric ring-type locating slot.
The present invention has and has improved effectively when listening to different audio frequency, and the accuracy of diaphragm for stethoscope polarization has strengthened the accuracy of judging the person's of seeing a doctor internal organs work audio frequency, has also prolonged the service life of vibrating diaphragm, makes the easier localized beneficial effect of vibrating diaphragm.

The specific embodiment
Embodiment: the present invention is described further in conjunction with Fig. 1, Fig. 2, Fig. 3
A kind of resetting means after displacement of diaphragm for stethoscope, involving vibrations film 3, seal ring set 8 and stethoscope tin body 1; Seal ring set 8 is described vibrating diaphragm 3 and stethoscope tin body 1 sealing and fixing, forms between vibrating diaphragm 8 and the similar bowl-shape sound collecting surface of being located on the described stethoscope tin body 15 to collect sound chamber 4, is provided with ring-type limited step 9 at the rim of a bowl place of sound collecting surface 5; Vibrating diaphragm 3 places in the described ring-type limited step 9; Be provided with spring 2 in the collection sound chamber 4, an end of spring 2 contacts with vibrating diaphragm 3, and the other end is fixed in sound collecting surface 5.
In conjunction with Fig. 1 as can be known, also be provided with the ring-type locating slot 6 that is used for fixing elastomer 2 on sound collecting surface 5, an end of spring 2 fixedly places in the ring-type locating slot 6.
Wherein, as shown in Figure 1, elastomer 2 can be spring; Vibrating diaphragm 3 is a metal material.
During use: vibrating diaphragm 3 can change by vibrating diaphragm 3 distortion with the volume of sound collecting surface 5 by the cavity 4 of seal ring set 8 sealing formation, after with vibrating diaphragm 3 contact patients, user active force and tin bulk 1, patient's counteracting force and vibrating diaphragm 3 make vibrating diaphragm 3 produce the position and become.Change the active force that imposes on tin bulk 1 according to the demand of user, reaching the volume that changes collection sound chamber 4, thus effect when reaching the sound of listening to different audio frequency.
When user active force and tin bulk 1, patient's counteracting force and vibrating diaphragm 3 drive spring 2 by vibrating diaphragm deformation take place, and after the pressure that will put on tin bulk 1 was withdrawn, spring 2 deformation disappeared, and 3 of vibrating diaphragms are become restore.
Because vibrating diaphragm 3 places in the described ring-type limited step 9; And spring 2 one ends are fixed in the annular positioning groove 6, and the other end contacts with the one side of vibrating diaphragm 3, so vibrating diaphragm 3 can only move up and down along spring 2.
On the sound collecting surface 5 of tin bulk 1, be provided with and change sound limited step 7.Change 7 position-limiting actions of sound limited step, the amplitude that constrained vibration film 3 moves up and down is so that listen to different audio frequency more effectively, exactly.
Claims (2)
1, a kind of resetting means after displacement of diaphragm for stethoscope, involving vibrations film, seal ring set and stethoscope tin body; Described seal ring set is with described vibrating diaphragm and described stethoscope tin body sealing and fixing, described vibrating diaphragm and be located at and form collection sound chamber between the similar bowl-shape sound collecting surface on the described stethoscope tin body, it is characterized in that: the rim of a bowl place at described bowl-shape sound collecting surface is provided with the ring-type limited step; Described vibrating diaphragm places in the described ring-type limited step; Be provided with spring at described collection sound intracavity, the one end contacts with described vibrating diaphragm, and the other end is fixed on the described sound collecting surface.
