Description

Technical Field

[0001] The utility model belongs to the field of pediatrics, and more specifically, particularly relates to a stethoscope. Background Art

[0002] A stethoscope is an acoustic medical device that transmits sound through vibration to obtain the sounds of the activities of internal organs of the human body. Through the stethoscope, a doctor can quickly learn about the operation of the human organs and assist the doctor in medical diagnosis. Currently, during the clinical diagnosis of pediatric medicine, the traditional stethoscope places a small disc-shaped resonator on the skin of the pediatric chest, and then the earpieces of two sound guide tubes transmit the vibration sounds of the internal organs in the chest cavity to the doctor's ears. During the auscultation process, the contact surface where the disc-shaped resonator fits with the child's skin is often relatively cold. Since the chest skin of a smaller child is relatively sensitive and the disc-shaped resonator itself does not have the ability to warm, the disc-shaped resonator often causes discomfort when fitting with the child's chest for auscultation, making the smaller child cry, which is not conducive to the doctor's auscultation work on the child. In addition, the earpieces of the traditional stethoscope are only inserted into the doctor's ear holes, and the earpiece structure is exposed, and external noise is extremely likely to contaminate the sound transmitted by the stethoscope, which is not conducive to the doctor's diagnosis of the condition through the sound.

[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] Such as Figures 1-9As shown, the utility model provides a stethoscope, including a three-way tube 8; a sound guide hose 9 is bonded to the sound inlet end of the bottom end of the three-way tube 8, a resonator 11 is installed at the other end of the sound guide hose 9, a handle 10 is connected to the front end of the resonator 11 by bolts, two groups of sound outlet ends at the top of the three-way tube 8 are bonded to soft tubes 6 respectively, a sound guide tube 4 is installed at the top of the soft tube 6, and an earpiece 2 is installed at the end of the sound guide tube 4; it also includes an earmuff 1, a housing 7, a button switch 14, a battery 15, a heat conductive sheet 17 and a cotton pad 19; the number of the sound guide tubes 4 is two groups, and the outer side surface of each group of sound guide tubes 4 is welded and connected to a sleeve 13, and the outer side surface of the sleeve 13 is provided The outer side of the sound guide tube 4 is bonded with an inner cover 3, and the outer side of the sound guide tube 4 is welded with a U-shaped leaf spring frame 5; the top of the casing 7 is connected to a battery compartment cover 12 by bolts, and the upper side of the battery compartment cover 12 is provided with a through groove, and a USB charging socket 18 is installed in the through groove of the battery compartment cover 12, and the USB charging socket 18 is connected to the battery 15 through a wire. A button switch 14 is installed on the rear side of the casing 7, and the button switch 14 is connected to the battery 15 through a wire; a micro-electric heater 16 is bonded to the rear side of the heat conductive sheet 17, and the micro-electric heater 16 is connected to the button switch 14 through a wire; the earmuff 1 is bonded to the cotton pad 19.

[0025] When the utility model performs the warming work of the resonator 11, the handle 10 is held, and the resonator 11 connected by the bolts at the rear end of the handle 10 is embedded in the groove of the casing 7, and the handle 10 moves downward along the slide groove on the front side of the groove of the casing 7 until the resonator 11 moves to the bottom of the groove. At this time, the heat conducting sheet 17 is opposite to the resonator 11 front and back, and the button switch 14 installed on the rear side of the casing 7 is pressed. The button switch 14 controls the power supply line of the power supply battery 15 and the micro-electric heating sheet 16 to be connected, and the power supply battery 15 supplies power to the micro-electric heating sheet 16, and the micro-electric heating sheet 16 converts electrical energy into thermal energy. The heat generated by the micro-electric heating sheet 16 is transferred to the skin contact surface of the resonator 11 through the copper heat conducting sheet 17, and the warming work of the resonator 11 is performed. When it is necessary to use the stethoscope for medical auscultation, the two groups of sound guide tubes 4 are moved by both hands, so that the sound guide tubes 4 overcome the U-shaped leaf spring frame 5, and then the two sets of ear pieces 2 are respectively inserted into the left ear hole and the right ear hole. At this time, the two sets of inner covers 3 are respectively fitted on the outside of the left ear hole and the right ear hole for sealing. Then the earmuff 1 is manually rotated. Since the threaded through hole of the earmuff 1 is meshed and connected to the threaded structure on the outer side of the sleeve 13, the earmuff 1 is moved left and right along the thread of the sleeve 13 at the top of the sound guide tube 4 until the cotton pads 19 on the edge of the cover body of the two sets of earmuffs 1 are respectively fitted on the left and right sides of the human head. At this time, the doctor's ears are located inside the cover body structure of the earmuff 1 to block the external sound environment. Then, the handle 10 is held and moved upward along the slide groove on the front side of the groove. The handle 10 takes the warmed resonator 11 out of the groove of the casing 7. Finally, the warm resonator 11 is fitted on the chest skin of the child for auscultation to avoid the cold touch of the resonator 11 from irritating the child.

[0026] In the embodiments of the present disclosure, the number of the earcups 1 is two groups, and the earcups 1 are symmetrically distributed left and right. Each group of earcups 1 has a concave cover structure. A threaded through-hole structure that penetrates left and right is provided at the central part of the earcup 1.

The cotton pads 19 are respectively bonded to the edge positions of the concave covers of the two groups of earcups 1. By using the soft characteristics of the sponge, the cotton pad 19 is closely attached to the skin around the human ear. The open porous structure of the sponge disperses the sound wave energy from the outside and converts it into tiny heat, thereby blocking the internal sound environment of the earcup 1 from the outside sound environment.

[0028] In the embodiments of the present disclosure, the number of the inner covers 3 is two groups. Each group of inner covers 3 is a thin sheet made of soft silicone. The two groups of inner covers 3 are symmetrically distributed at the right end of the right earpiece 2 and the left end of the left earpiece 2 respectively. When the earpiece 2 penetrates into the ear canal, the soft silicone inner cover 3 fits on the auricle to block the external auditory canal, improving the sound insulation effect.

[0029] In the embodiments of the present disclosure, a groove is provided on the upper side surface of the housing 7. A circular through-hole is provided at a position near the bottom of the rear side surface inside the groove. The diameter of the circular through-hole is the same as the diameter of the resonator 11. A heat-conducting sheet 17 is bonded inside the circular through-hole of the housing 7. When the resonator 11 is embedded in the groove of the housing 7, the resonator 11 and the heat-conducting sheet 17 face each other front and back.

A chute with an upper-side opening is provided on the front side surface of the groove of the housing 7. The handle 10 is inserted into the chute, so that the handle 10 drives the resonator 11 to move up or down along the chute, facilitating the taking and placing of the resonator 11 in the groove.

[0030] In the embodiments of the present disclosure, the heat-conducting sheet 17 is a copper disk-shaped structure. The diameter of the heat-conducting sheet 17 is the same as the diameter of the resonator 11. By using the good heat-conducting performance of the copper material, the heat-conducting sheet 17 evenly transfers heat to the skin contact surface of the resonator 11.

[0031] The installation methods, connection methods, or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc. Moreover, the specific structures, models, and coefficient indicators of all its components are its own technologies, and any implementation that can achieve its beneficial effects is acceptable. The above-mentioned push button switch 14, battery supply 15, micro electric heating sheet 16, and USB charging socket 18 are all common devices on the market. When purchased and used, only connect them according to the user manual purchased together to use, so they will not be elaborated here.
