Example (b):

referring to fig. 1 and 2, the present embodiment provides an anti-infection stethoscope, which includes a stethoscope head 1, a sound-guiding tube 2, and an earhook 3. The sound guiding duct 2 comprises a main duct 21, a first branch duct 22 and a second branch duct 23. The first branch pipe 22 and the second branch pipe 23 are both communicated with one end of the main pipe 21, so that the main pipe 21, the first branch pipe 22 and the second branch pipe 23 are combined into a Y shape. The other end of the main tube 21 is connected with the auscultation head 1.

The ear-hook 3 comprises a sound-emitting disc 31 and a fixed ear-hook 32. The hanging lug is arranged on the sound-emitting disc 31 in a way of being matched with the human ear, so that the sound-emitting disc 31 is fixed on the human ear through the hanging lug. The other end of the first branch pipe 22 and the other end of the second branch pipe 23 of the sound guide pipe 2 are respectively connected with a sound outlet disc 31. The side of the sound outlet disc 31 close to the human ear is provided with a plurality of sound outlet holes 311. After the sound is conducted to the two sound outlet discs 31 through the first branch pipe 22 and the second branch pipe 23, the sound is conducted to the human ear through the sound outlet holes 311. The structure of the ear hook and the sound disc 31 is similar to that of an ear hook earphone.

When in use, the sound outlet disc 31 is fixed on the ear of a person through the fixing hanging lug 32. The sound collected by the stethoscope head 1 is transmitted to the sound disc 31 through the main tube 21, the first branch tube 22 and the second branch tube 23 and then transmitted to the ears of the person.

The sound disc 31 of the infection-preventing stethoscope of the utility model replaces the ear-in type ear-hang 3 of the prior art. The sound outlet disc 31 is fixed outside the human ear, so that cross infection caused by the fact that the ear hook 3 extends into the human ear is effectively avoided, and safety and sanitation are achieved.

In this embodiment, the sound guide tube 2 is provided with a sound amplification unit 4 therein. The sound amplification assembly 4 includes a microphone 41, a speaker 42, and a control circuit board 43. The speaker 42 is disposed inside the main tube 21 and is located at one end of the main tube 21 near the first and

second branch tubes

22 and 23. The microphone 41 is disposed inside the main tube 21 and directed to the head 1. The microphone 41 and the speaker 42 are both connected to the control circuit board 43.

The circuit board is provided with an operational amplifier. The sound collected by the stethoscope head 1 is conducted to the microphone 41 through the main tube 21. The microphone 41 picks up the sound and sends an electric signal to the control circuit board 43. The operational amplifier amplifies the electrical signal and transmits the amplified signal to the speaker 42, thereby causing the speaker 42 to emit sound. The sound emitted from the speaker 42 is transmitted to the human ear through the sound-emitting disk 31. The sound amplifying assembly 4 can amplify weak sounds collected by the stethoscope head 1. The condition that the sound outlet disc 31 is matched with the outside of the human ear to cause that the doctor can not hear the sound collected by the auscultation head 1 is avoided. Meanwhile, after the sound disc 31 is matched with the outside of the human ear, the sound generated by the vibration or friction of the sound guide tube 2 can not be transmitted into the human ear well, and the interference of noise to doctors can be further reduced.

The speaker 42 is disposed inside the main pipe 21 and is located at one end of the main pipe 21 close to the first branch pipe 22 and the second branch pipe 23. The sound emitted from the speaker 42 is transmitted to one ear through the first branch pipe 22 and the second branch pipe 23, respectively. Only one speaker 42 is required to allow sound to be heard in both ears. Avoiding the need to have one speaker 42 per sound-emitting disc 31. While also avoiding simultaneous wiring of the control circuit board 43 to both speakers 42. The stethoscope has simple structure and low production cost.

In practice, a battery is also connected to the control circuit board 43. For convenient charging, the battery is connected with a coil for wireless charging. The sound amplification assembly 4 is placed inside the main pipe 21, and then wireless charging can be performed, so that the replacement of a battery is avoided, and further, the main pipe 21 is prevented from being frequently disassembled.

In this embodiment, the control circuit board 43 is provided with a data transmission module. The data sending module can be a Bluetooth module, a WiFi module and the like. And a data receiving module is arranged in cooperation with the data sending module. The data receiving module is a Bluetooth module or a WiFi module matched with the data sending module. The data receiving module is connected with a mobile phone or a computer. After the stethoscope collects sound, the data sending module sends the data to the data receiving module, and then sends the data to a mobile phone or a computer. This enables the sounds collected by the stethoscope to be heard by multiple persons simultaneously. The diagnosis of the illness state is facilitated by cooperation of a plurality of people, and the teaching is also facilitated. After the data are sent to the data receiving module, the data can be stored through a mobile phone or a computer, and later-stage checking is facilitated.

In this embodiment, a flared sound cavity is provided inside the sound output disk 31. The sound guide tube 2 is communicated with the smaller end of the sound cavity. The sound is transmitted to the sound emitting disc 31, then diffused inside the sound emitting disc 31, and finally transmitted to the human ear through the sound emitting holes 311. Since the sound-emitting disk 31 is disposed outside the human ear, the sound volume coming out from one position may cause the single sound-emitting hole 311 to be blocked by the auricle. The arrangement of the present embodiment can disperse and simultaneously emit sound from the sound outlet holes 311 at a plurality of positions. Ensuring that the human ear can hear the sound coming from the audio disc 31.

In this embodiment, the sound emitting disc 31 is wrapped with a cleaning cover. The cleaning sleeve is in a bag shape. The opening of the cleaning sleeve can be contracted. The cleaning sleeve is made of sponge. The structure of the cleaning sleeve makes it replaceable. Before the stethoscope is used, the cleaning sleeve is sleeved outside the sound outlet disc 31. This is effective in avoiding infection. Meanwhile, the cleaning sleeve also makes the wearing more comfortable.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
