Abstract
Description
Technical Field
[0001] The utility model relates to a stethoscope technology, in particular to a stethoscope for internal medicine. Background Art
[0002] The front end of the stethoscope is a large membrane cavity. When the sound waves in the body stimulate the membrane cavity, the sealed gas in the stethoscope vibrates accordingly. At the end that is inserted into the ear, due to the narrow cavity, the amplitude of the gas vibration is much larger than that at the front end, thereby amplifying the sound wave vibration in the patient's body.
[0003] Since the size of each person's head is different and the distance between the two ears is different, it is necessary to adjust the tightness of the listening part. The existing stethoscope is equipped with a spring part, but the spring part will cause a large clamping force on the listening part when used by doctors with large heads, and it is not convenient to adjust the tightness. If the listening part does not fit the ear cavity, it is easy to fall off, or the auscultation effect is poor. Utility Model Content
[0004] In order to solve the defects of the prior art mentioned above, the utility model proposes a stethoscope for internal medicine.
[0005] The technical solution of the utility model is achieved in this way:
[0006] A stethoscope for internal medicine, characterized in that it comprises a listening part, a conducting part and a picking-up part, wherein the listening part is connected to the picking-up part through the conducting part, the conducting part has a bifurcated part, the listening part is composed of a left sound guide tube and a right sound guide tube, and the left sound guide tube and the right sound guide tube are respectively connected to the bifurcated part.
[0007] The bifurcated portion has symmetrically arranged hook parts, and an adjusting member is provided in the middle of the symmetrically arranged hook parts. A first rotating member and a second rotating member are respectively provided on both sides of the adjusting member. The first rotating member is connected to the hook part through a first elastic member, and the second rotating member is connected to the hook part through a second elastic member.
[0008] In the internal medicine stethoscope of the utility model, the first elastic member and the second elastic member are springs.
[0009] In the internal medicine stethoscope of the utility model, one end of the first elastic member and the second elastic member is provided with a first hook, the other end is provided with a second hook, and a telescopic part is provided in the middle.
[0010] In the internal medicine stethoscope of the utility model, the first hook is connected to the hook portion, and the second hook is connected to the first rotating member and / or the second rotating member.
[0011] In the internal medicine stethoscope of the present invention, the first rotating member is provided with a first threaded portion, the second rotating member is provided with a second threaded portion, a through hole is provided in the middle of the adjusting member, one end of the through hole is provided with a first internal thread matching the first threaded portion, and the other end is provided with a second internal thread matching the second threaded portion.
[0012] In the medical stethoscope of the utility model, the thread directions of the first internal thread and the second internal thread are opposite.
[0013] The implementation of the internal medicine stethoscope of the utility model has the following beneficial effects: the internal medicine stethoscope has a simple structure and a clever design, and the clamping force can be changed by rotating the adjustment member, so that it is convenient for doctors to wear it. After the first elastic member and the second elastic member are compressed or stretched, they can be compressed or stretched again, so that the left sound guide tube and the right sound guide tube can clamp the ear cavity and fit closely with the ear cavity, thereby improving the sound pickup efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 This is a schematic diagram of the structure of the internal medicine stethoscope of the utility model;
[0015] Figure 2 for Figure 1 A local enlarged view of point A in FIG.
[0016] Figure 3 It is a schematic structural diagram of the adjusting member, the first rotating member, the second rotating member, the first elastic member, the second elastic member and the hook part in the utility model. DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0018] like Figures 1 to 3 As shown, the internal medicine stethoscope of the utility model includes a listening part 1, a conducting part 2 and a picking up part 3. The listening part 1 is connected to the picking up part 3 through the conducting part 2. The conducting part 2 has a bifurcated part 4. The listening part 1 is composed of a left sound guide tube 5 and a right sound guide tube 6. The left sound guide tube 5 and the right sound guide tube 6 are respectively connected to the bifurcated part 4.
[0019] The forked portion 4 has a symmetrically arranged hook portion 7, an adjusting member 8 is arranged in the middle of the symmetrically arranged hook portion 7, a first rotating member 9 and a second rotating member 10 are arranged on both sides of the adjusting member 8, the first rotating member 9 is connected to the hook portion 7 through a first elastic member 11, and the second rotating member 10 is connected to the hook portion 7 through a second elastic member 12. The adjusting member 8 rotates, so that the first rotating member 9 and the second rotating member 10 move in the middle of the adjusting member 8, and the first elastic member 11 is kept compressed or stretched.
[0020] Of course, since the elastic member has elasticity, even if the elastic member is stretched or compressed, the elastic member can still be kept compressed or stretched if the stretching limit or the compression limit is not reached.
[0021] The first elastic member 11 and the second elastic member 12 are springs. A first hook 13 is provided at one end of the first elastic member 11 and the second elastic member 12, a second hook 14 is provided at the other end, and a telescopic portion 15 is provided in the middle. The first hook 13 is connected to the hook portion 7, and the second hook 14 is connected to the first rotating member 9 and / or the second rotating member 10.
[0022] The first rotating member 9 is provided with a first threaded portion 16, the second rotating member 10 is provided with a second threaded portion 17, a through hole 18 is provided in the middle of the adjusting member 8, one end of the through hole 18 is provided with a first internal thread 19 matched with the first threaded portion 16, and the other end is provided with a second internal thread 20 matched with the second threaded portion 17. The thread directions of the first internal thread 19 and the second internal thread 20 are opposite.
[0023] The spring sheet in the prior art keeps the left sound guide tube 5 and the right sound guide tube 6 in a cross arrangement. When in use, the left sound guide tube 5 and the right sound guide tube 6 need to be separated. However, for doctors with large heads, the clamping force is large, resulting in excessive force on the ear cavity and discomfort.
[0024] The adjusting member 8 in the present application can rotate to keep the first rotating member 9 and the second rotating member 10 moving in the through hole 18, so that the first rotating member 9 drives the first elastic member 11 to stretch or compress, and the second rotating member 10 drives the second elastic member 12 to stretch or compress.
[0025] When the first elastic member 11 and the second elastic member 12 are stretched, the left sound guide tube 5 and the right sound guide tube 6 are moved closer to the center, and when the first elastic member 11 and the second elastic member 12 are compressed, the left sound guide tube 5 and the right sound guide tube 6 are pushed outwards, so as to be suitable for doctors with different head sizes to wear.
[0026] In addition, the elastic member may also be a rubber member with elasticity.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
