Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an internal medicine stethoscope. Background Art
[0002] The stethoscope is a commonly used diagnostic device in internal medicine. Its basic structure mainly consists of a sound pickup part, a sound guide tube and an ear hook. During use, the stethoscope head is usually pinched with one hand, and then the ear hook needs to be removed and hung around the neck, and the stethoscope head is taken down and placed on the table. Due to the long length of the long rubber tube, one end of the sound pickup is easy to slip off the table and cause damage. In addition, the doctor can use the stethoscope to detect the murmur inside the patient's chest or abdominal cavity, so as to judge the pathological symptoms. However, during the auscultation process, the doctor is easily disturbed by external sounds, which affects the auscultation results. Therefore, it is necessary to further improve the noise-proof ability of the stethoscope. Utility Model Content
[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a medical stethoscope, and the specific technical solution is as follows:
[0004] An internal medicine stethoscope comprises a sound pickup and an ear hook, wherein the sound pickup is connected to the ear hook through a sound guide tube, and a rear base of the sound pickup is provided with an elastic bracelet fixedly connected thereto and capable of being put on a finger;
[0005] An earmuff is arranged outside the ear hook to wrap around the ear. The earmuff is a corrugated structure and can be freely expanded and contracted after being compressed. The overall shape is a horizontal "U"-shaped structure.
[0006] An adjusting piece is provided on the upper part of the sound guide tube to adjust the distance between the two ends of the sound guide tube.
[0007] Furthermore, the sound guide tube includes a first connecting plate, a second connecting plate, a through hole and a clamp, the first connecting plate is connected to the sound guide tube on one side, and the second connecting plate is connected to the sound guide tube on the other side. After the first connecting plate is connected to the second connecting plate, the through hole opened on the first connecting plate is passed through the clamp to control the distance between the sound guide tubes on both sides.
[0008] Furthermore, the first connecting piece and the second connecting piece are provided with a plurality of through holes at equal distances along the length direction thereof.
[0009] Furthermore, the earmuffs are made of rubber.
[0010] Furthermore, the first connecting piece and the second connecting piece are both 10-20 cm long and made of hard plastic.
[0011] The above technical solution has the following beneficial effects:
[0012] With the elastic sleeve bracelet provided by the utility model, the doctor can insert the other four fingers except the thumb into the elastic sleeve bracelet, and put the back of the hand close to the heart position of the person to be tested. After the test is finished, the hand can be taken away. There is no need to carry out the steps of taking and placing the microphone, which brings convenience and prevents the microphone from accidentally falling and bumping. At the same time, the doctor can also hold the base of the microphone for inspection, which is a normal hand-held inspection; the earmuffs cover the doctor's ears, and the corrugated structure can bend and fit with the skin outside the ears, thereby improving the sealing effect, reducing external noise, and improving the accuracy of diagnosis.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1: See Figure 1 and 2 The medical stethoscope shown in FIG. 1 includes a pickup 2 and an ear hook 3. The pickup 2 is connected to the ear hook 3 through a sound guide tube 1. Figure 3As shown, the rear base 22 of the pickup 2 is provided with an elastic bracelet 21 fixedly connected thereto and capable of being put on a finger;
[0023] The outside of the ear hook 3 is provided with an earmuff 31 that wraps around the ear. The earmuff 31 is a corrugated structure that can freely expand and contract after being compressed. The overall shape is a horizontal "U"-shaped structure. The upper half of the sound guide tube 1 is provided with an adjustment plate 44 to adjust the distance between the two ends of the sound guide tube 1. The earmuff 31 is made of rubber.
[0024] like Figure 4 As shown, the sound guide tube 1 includes a first connecting piece 41, a second connecting piece 42, a through hole 43 and a clamp 44. The first connecting piece 41 is connected to the sound guide tube 1 on one side, and the second connecting piece 42 is connected to the sound guide tube 1 on the other side. After the first connecting piece 41 and the second connecting piece 42 are connected, they are fixed through the through hole 43 opened on them through the clamp 44 to control the distance between the sound guide tubes 1 on both sides. The first connecting piece 41 and the second connecting piece 42 are provided with a plurality of through holes 43 at equal distances along their length direction. The first connecting piece 41 and the second connecting piece 42 are both 15 cm long and made of hard plastic.
[0025] In this embodiment, the inner dimensions of the earmuff 31 should be able to include the outline of a normal human ear. The earmuff 31 in this embodiment is round and is made of rubber material with elasticity and contractility, so that it can fit on the skin outside the ear to form a sealing structure and improve the sound insulation effect.
[0026] In this embodiment, the adjusting member is used to connect the two sound guide tubes 1 to control the distance between the two sound guide tubes 1, so as to prevent the distance between the two sound guide tubes from being too far, which affects the ear hook 3 from being unable to adapt to doctors with smaller heads.
[0027] When in use, the ear hook 3 is inserted into the ear, and the earmuff 31 covers the doctor's ear. The doctor can insert the other four fingers except the thumb into the elastic sleeve bracelet 21, and place the back of the hand close to the heart of the person to be tested. After the end, the hand can be removed. There is no need to perform the picking and placing steps for the pickup 2, which brings convenience and prevents the pickup 2 from accidentally falling and bumping. At the same time, the doctor can also hold the base 22 of the pickup 2 for inspection. If the distance between the two sound guide tubes 1 is far, which affects the use of the ear hook 3, the first connecting piece 41 and the second connecting piece 42 are brought close to each other and the clamp 44 is passed through the through holes 43 corresponding to the first connecting piece 41 and the second connecting piece 42 and then fixed.
[0028] The above description of the fan describes the basic principles and main features of the utility model. Technical personnel in this industry should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
