Stethoscopes are also used to listen to the blood flow in the intestines as well as in arteries and veins. Since the invention of the stethoscope in 1819, the stethoscope has been used to listen to the internal sounds of the human body as an aid in diagnosing certain diseases or health conditions. Prior to the invention of the stethoscope, the physician listened to the internal sounds of the human body by placing his ears on the patient's chest or elsewhere in close proximity to the patient's body.
The conventional stethoscope includes a sound receiving member (i.e., a stethoscope head), a main transmitting tube, a distal transmitting tube, and earplugs, which cause pain in the ears in the case where the earplugs are pressed against the ears for a long period of time, because the existing earplugs are directly inserted into the ears and have a hard texture. At present, a sponge sleeve is arranged around the earplugs of part of the stethoscope, so that the stethoscope is similar to the structure of the earphones, but because the ears of different people have different shapes and sizes, a plurality of sponge sleeves need to be arranged in order to be worn by different people, and the replacement of the sponge sleeves is troublesome.

A cover plate 80 is fixed on the periphery of the earplug 40, an annular air bag 81 is arranged on the side surface of the cover plate 80 facing the earplug 40, and the air bag 81 is arranged along the edge of the cover plate 80; after the earplug 40 is worn, the air bag 81 is inflated, and the air bag 81 surrounds the ear, so that the problem that the earplug 40 is directly pressed on the ear to cause ear pain after long-time wearing can be avoided, and in addition, the air bag 81 also has the function of reducing noise.
The air bag 81 is connected with a rubber inflatable ball 50, the rubber inflatable ball 50 is fixed on the main conduction pipe 20, and the main conduction pipe 20 penetrates through the rubber inflatable ball 50, so that the falling of the rubber inflatable ball 50 can be avoided. A negative pressure pipe is arranged above the rubber inflatable ball 50, the negative pressure pipe surrounds the periphery of the main conduction pipe 20, and a flow guide channel is arranged between the negative pressure pipe and the main conduction pipe 20; the flow guide channel sequentially comprises an inlet section 61, a throat 62 and a diffusion section 63 from bottom to top, the rubber inflatable ball 50 is communicated with the inlet section 61, and therefore airflow is formed in the flow guide channel by extruding the rubber inflatable ball 50; the cross-sectional area of the throat 62 is smaller than the cross-sectional areas of the inlet section 61 and the diffuser section 63, and the throat 62 compresses the airflow as it passes through the throat 62, so that the velocity of the airflow through the throat 62 increases, causing the pressure at the throat 62 to decrease. The periphery of the negative pressure pipe is also provided with a water bag 90, the throat part 62 is communicated with the water bag 90 through a water suction pipe 91, and the water suction pipe 91 extends into the water bag 90; when the rubber inflatable ball 50 is squeezed, airflow is formed in the negative pressure pipe, the throat part 62 sucks water from the water bag 90, the air meets the water at the throat part 62, and when the air enters the diffusion section 63 from the throat part, the air is diffused, so that the water is atomized in the diffusion section 63 along with the air.
The air bag 81 is communicated with the diffusion section 63 of the negative pressure pipe through a pipeline and is fixed on the tail end conduction pipe 30 through a line clamp; an air outlet one-way valve 64 is arranged in the diffusion section 63, and an air inlet one-way valve 51 is arranged in the rubber inflatable ball 50; when the rubber inflatable ball 50 is squeezed, the air outlet one-way valve 64 is opened, air can be squeezed into the air bag 81, and the air inlet one-way valve 51 is opened after the air bag 81 is released, so that the rubber inflatable ball 50 sucks air from the outside through the air inlet one-way valve 51; so that the rubber inflatable ball 50 forms a structure similar to a pump; further, the air is continuously supplied into the air cell 81 by continuously pressing the rubber balloon 50, so that the air cell 81 is expanded. In addition, a first one-way valve is arranged on the side wall of the water bag 90, the first one-way valve is in threaded connection with the side wall of the water bag 90, and when the pressure in the water bag 90 is reduced, the first one-way valve is opened to ensure that the throat part 62 can normally suck water from the water bag 90. The first check valve also prevents water in the water bladder 90 from flowing out, and by removing the first check valve, water can be added to the water bladder 90. In addition, the diffuser section is also provided with fan blades 66, when the airflow passes through the diffuser section 63, the airflow pushes the fan blades to rotate, and meanwhile, the water mist impacts on the fan blades 66 to further promote the atomization of the fan blades; after the water mist is adsorbed on the fan blades 66, the water mist is thrown outwards under the action of centrifugal force formed by rotation of the fan blades 66, so that the gas atomization is promoted.
The cover plates 80 are connected by the arc plates 70, and the arc plates 70 are made of steel sheets having elasticity, so that the earplugs 40 are prevented from falling off when the arc plates 70 are worn on the head; and the arc-shaped plate 70 has elasticity, so that the air bag 81 can be pressed around the ear, and the noise isolation effect is better. The arc plate 70 is made of two steel sheets slidably coupled to each other, so that the arc plate 70 is stretchable and the stethoscope can be applied to more people. In addition, a pressure relief valve 65 is further arranged on the diffuser section 63, and the pressure relief valve 65 is positioned above the air outlet one-way valve 64, namely the pressure relief valve 65 is positioned between the air bag 81 and the air outlet one-way valve 64; when the air pressure in the air bag 81 needs to be reduced, the relief valve 65 may be opened.
The specific working process of the easily-worn stethoscope of the embodiment is as follows:
after wearing the earplug 40, by repeatedly squeezing the rubber balloon 50, air will enter the bladder 81 through the negative pressure tube, and since the flow rate of the air flow through the throat 62 is increased, the pressure at the throat 62 is decreased, and the suction tube 91 will suck water from the water bladder 90 into the throat 62. The water is atomized in the negative pressure pipe and enters the air bag 81 in the form of water mist; therefore, when the weather is hot, water is filled in the water bag 90, and water is sprayed into the air bag 81 to achieve the purpose of cooling. In addition, the air in the air bag 81 can be released by opening the relief valve 65, and the size of the expanded air bag 81 can be adjusted by matching the rubber inflatable ball 50 with the relief valve 65, so that the air bag can be suitable for different people.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
