Background

From ancient times, auscultation was an important diagnostic method. With the development of modern medicine, a stethoscope is invented, and doctors can make more accurate diagnosis on patients through the stethoscope. Currently, stethoscopes are the most commonly used diagnostic tools for modern doctors. The stethoscope has been improved in appearance and sound transmission mode since its clinical application, but its basic structure is not changed much, and it is mainly composed of stethoscope head, sound guide tube and earplug.

When using the stethoscope, a doctor inserts the earplugs into the ear canal and then brings the stethoscope head into contact with the body of a patient, thereby collecting and amplifying sounds emitted from the heart, lungs, arteries, veins and other internal organs of the patient, and transmitting the sounds to the ears of the doctor through the sound guide tube, so that the doctor can clearly distinguish the details of the sounds emitted from the internal organs of the patient, thereby performing diagnosis of diseases.

In the process of clinical diagnosis, the auscultation sounds of organs such as the heart, the lung and the like are weak, so that doctors cannot hear clear auscultation sounds, and can easily ignore some details and even cause misdiagnosis. However, during auscultation, there are often many noises, such as: crying and screaming sound of the examinee, friction sound between the sound guide tube and clothes, and speaking sound in the examination room. The existing portable stethoscope can not filter noise in the using process, has weak noise resistance and can not meet the using requirement of clinical diagnosis.

Referring to fig. 1, 2 and 3, the present invention provides a portable stethoscope for medical surgery, comprising: sound pick-up 1, leading tone pipe 2, three-way pipe 3, listening pipe 4 and earplug 5.

Wherein, the sound pick-up 1 is communicated with one branch of the three-way pipe 3 through the sound guide pipe 2, and the pair of listening pipes 4 are respectively communicated with the other two branches of the three-way pipe 3. When a doctor makes a diagnosis, the sound pickup 1 needs to be attached to the body of the examinee. The sound collector 1 can collect sounds generated by the organs of the examinee during vibration, and transmit the vibrations through the sound guide tube 2, the three-way tube 3 and the listening tube 4, and finally the sounds are transmitted from the output end of the listening tube 4. The doctor diagnoses the examinee by the sound transmitted from the output end of the sound tube 4.

Specifically, as shown in fig. 2, in order to facilitate auscultation by a doctor, an earplug 5 is connected to an output end of the listening tube 4, and the earplug 5 includes a sleeve 51 and a fitting portion 52. The sleeve 51 is sleeved on the output end of the listening tube 4, the fitting part 52 surrounds the sleeve 51, and the sleeve 51 is connected with the fitting part 52 through a transitional curved surface. The sleeve 51 and the attaching portion 52 are integrally formed. The fitting portion 52 is adapted to fit the ear canal of the user, preventing the earplug 5 from falling off, so as to facilitate the stethoscope being worn by the doctor. In order to further increase the friction between the attachment portion 52 and the ear canal, the outer surface of the attachment portion 52 is further provided with a plurality of elastic ribs 53, the elastic ribs 53 extending in the circumferential direction of the attachment portion 52 of the earplug 5, so that the elastic ribs 53 are annular. A plurality of elastic ribs 53 are provided on the outer surface of the attachment portion 52 at intervals along the extending direction of the sleeve 51. When the user wears the earplug 5 into the ear canal, the elastic ribs 53 are deformed by the pressure of the ear canal, and under the action of the elastic force, the elastic ribs 53 abut against the ear canal, so that the friction force between the earplug 5 and the ear canal is increased, and the earplug 5 is prevented from falling off. In addition, the elastic ribs 53 are tightly attached to the auditory meatus of the doctor, so that the interference of part of environmental noise can be avoided, and the auscultation accuracy of the doctor is improved.

The fitting part 52 is ellipsoidal, so that a containing cavity 54 is formed between the sleeve 51 and the fitting part 52, and the sound absorption cotton 6 is arranged in the containing cavity 54. The sound absorption cotton 6 is adhered in the containing cavity 54 through glue. When ambient noise arouses the vibration of air to when making the sound wave spread into doctor's ear, can influence doctor's auscultation effect greatly, inhale sound cotton 6 and can absorb the sound wave through the setting, in order to reduce the influence of ambient noise to doctor's auscultation. In addition, when the earplug 5 is worn in the ear canal of a doctor, the output end of the listening tube 4 is communicated with the ear canal of the doctor through the sleeve 51, so that the vibration sound of the organs of the examinee can be transmitted into the ear canal of the doctor through the sleeve 51, the sound-absorbing cotton 6 does not weaken the transmission effect of the vibration sound of the organs of the examinee, and the doctor can clearly hear the fine sound emitted by the organs of the examinee.

The earplug 5 is made of silicone. The silica gel is easy to manufacture and form, and the industrial processing and forming are simpler. And silica gel texture is soft and skin-friendly, causes the anaphylactic reaction of human skin less, and earplug 5 made of silica gel can not produce obvious foreign body sensation in the wearing process, is fit for wearing and auscultation for a longer time. Of course, it will be appreciated that the earplug 5 may also be made of other soft, skin-friendly materials, such as: memory sponges, and the like.

Referring to fig. 1, 3, 4 and 5, since the vibration sound of the internal organs of the human body is small, the conventional stethoscope cannot collect and amplify the sound of the internal organs of the human body well. In order to improve the sound receiving effect of the sound pickup 1 and further reduce the influence of environmental sounds, the sound pickup 1 is provided with a first annular end surface 11 and a second annular end surface 12, the first annular end surface 11 and the second annular end surface 12 are coaxially arranged, and the second annular end surface 12 surrounds the first annular end surface 11. The sound pick-up 1 further comprises a diaphragm 14, and the diaphragm 14 is attached to the edge of the first annular end surface 11 and encloses with the first annular end surface 11 to form a sound collection cavity 15. The second annular end surface 12 encloses a flared outwardly flaring 13, which flaring 13 is located outside the sound-collecting chamber 15.

As shown in fig. 4, a mounting portion 17 is disposed between the first annular end surface 11 and the second annular end surface 12 of the sound pickup 1, the mounting portion 17 is an annular groove, and the mounting portion 17 surrounds the first annular end surface 11. The side wall of the mounting portion 17 is provided with a thread and can engage with a fastener 18 to mount the diaphragm 14. Specifically, as shown in fig. 5, the fixing member 18 includes a connecting portion 181, the connecting portion 181 is annular, a side wall of the connecting portion 181 is provided with a screw thread, and the fixing member 18 is screwed to the mounting portion 17 through the connecting portion 181. One end of the connecting portion 181 extends inward to form a pressing portion 182, and when the fixing member 18 is screwed to the mounting portion 17, the pressing portion 182 can press the diaphragm 14 against the edge of the second annular end surface 12, so that the diaphragm 14 and the second annular end surface 12 cooperate to form the closed sound collecting cavity 15.

The sound pickup 1 is provided with a sound guide hole 16, one end of the sound guide hole 16 is communicated with the sound collection cavity 15, and the other end is communicated with the sound collection pipe. When a doctor auscultates, the flared opening 13 of the sound pick-up 1 is tightly attached to the body of a patient, and the flared opening 13 can tighten the surface of the listening part of the patient, so that the sound emitted by the visceral organs transmits higher-frequency sound through the tightened surface of the listening part, and the doctor can listen to the fine sound of the visceral organs of the patient conveniently. Specifically, the sound generated by the organ vibration of the subject causes the annular curved surface, the diaphragm 14, and the air in the sound collection chamber 15 to vibrate, and the sound wave is reflected and refracted in the sealed sound collection chamber 15, thereby amplifying the sound of the organ of the subject. The amplified sound is transmitted to the ears of the doctor through the sound guide hole 16, the sound guide tube 2 and the sound listening tube 4. The doctor can diagnose the examinee based on the heard sound.

Therefore, the stethoscope can effectively reduce the influence of environmental noise so as to improve the definition of doctors during auscultation. Moreover, the stethoscope can effectively collect and amplify the sound of the visceral organs of the patient so as to improve the diagnosis accuracy of doctors.

Referring to fig. 1, the sound guide tube 2 is made of PVC. PVC, i.e. polyvinyl chloride, and the sound guide tube 2 made of polyvinyl chloride has good elasticity and good vibration guide function, so that sound waves can be more easily transmitted to the sound tube 4. However, the sound guide tube 2 made of PVC is liable to generate touch sound when touched, for example: in the auscultation process, when the sound guide tube 2 contacts or rubs with the clothes of a doctor or a patient, the tube wall of the sound guide tube 2 can vibrate, and the sound waves generated by the vibration can cause resonance in the tube, so that a large touch sound is formed. In the auscultation process, touching the sound guide tube 2 is almost inevitable, and therefore, the outer side of the tube wall of the sound guide tube 2 is coated with a sound insulation layer to reduce the touch sound generated when touching the sound guide tube 2.

Specifically, the soundproof layer is formed by weaving vegetable fibers, such as cotton fibers, hemp fibers, and the like. Of course, it is understood that the acoustical layer can also be woven from other fibrous materials, such as: polyester fibers, and the like. The acoustical layer formed by weaving the fibrous material has a plurality of pores. When sound waves pass through the sound insulation layer, the sound waves can be transmitted in a plurality of closed fine holes, and according to the conduction characteristics of the sound waves, the vibration potential energy of the sound waves can be greatly consumed and attenuated, so that the external noise is effectively reduced and is transmitted into the rubber tube cavity.

In addition, the outer surface of the sound insulation layer formed by weaving the fiber material has certain lines, so that the friction force can be increased, a doctor can conveniently grasp the sound insulation layer, and the portability of the stethoscope is improved.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
