Description

Technical Field

[0001] The utility model relates to a novel stethoscope, in particular to a novel stethoscope, and belongs to the technical field of medical equipment. Background Art

[0002] The stethoscope is the most commonly used diagnostic tool for internal medicine, surgery, gynecology and pediatrics. It is the symbol of doctors. Modern medicine began with the invention of the stethoscope. Since the stethoscope was first used in clinical practice on March 8, 1817, its appearance and sound transmission method have been continuously improved, but its basic structure has not changed much. It mainly consists of a sound pickup part (chest piece), a transmission part (rubber hose) and a listening part (ear piece).

[0003] At present, most of the stethoscopes on the market are generally used by only one doctor to auscultate the patient. However, in clinical work, in order to improve the diagnosis and treatment effect of the disease, it is often necessary to cooperate with multiple disciplines and auscultate multiple parts at the same time. In addition, in the clinical teaching process, teachers and students are also required to auscultate the same part at the same time to make the knowledge points clear. Obviously, this type of stethoscope cannot meet this condition. The existing patent is a new type of stethoscope, and the patent authorization number is CN 214965807U. The sealing cover can seal the other three threaded tubes when not in use to prevent external dust and impurities from falling into the threaded tube, causing dust to enter the inside of the stethoscope head and affect the normal use of the stethoscope head. At the same time, it avoids the uneven touch and ensures the "integrated" appearance.

[0004] However, the conducting rod in the patent authorization number CN 214965807 U often adjusts its clamping force through a spring plate. Since the head widths of different users are different, the opening angles of the spring plate are different. The larger the opening angle of the spring plate, the greater the clamping force of the spring plate, since the elastic coefficient is a fixed value. If the user wears it for a long time, it is easy to cause discomfort in the ear clamping. For this reason, we propose a new stethoscope. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a new stethoscope.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A novel stethoscope is designed, comprising a conductive rod, an earplug symmetrically mounted on the top of the conductive rod, a conductive hose conductively connected to the bottom of the conductive rod, and a stethoscope head mounted on the end of the conductive hose, wherein an adjustment component is mounted on the conductive rod;

[0008] The adjustment component includes a metal spring sheet symmetrically fixedly connected to the conduction rod and arranged in an arc-shaped structure, a second connecting ear integrally formed at the bottom of the metal spring sheet, an adjustment rod inserted between the second connecting ears, threaded portions provided at both ends of the adjustment rod, a nut threadedly connected to the threaded portion, a flat washer sleeved on the end of the adjustment rod and with both side surfaces respectively abutting against the second connecting ear and the nut, and a spring sleeved on the middle of the adjustment rod and with both ends abutting against the second connecting ear.

[0009] Preferably, a protective cover shell is detachably connected to the outer side of the stethoscope head, and the inner diameter of the protective cover shell is matched with the outer diameter of the stethoscope head.

[0010] Preferably, a sealing rubber ring is inlaid on the inner wall of the protective cover shell, and the sealing rubber ring abuts against the outer wall of the stethoscope head.

[0014] The novel stethoscope proposed by the utility model has the following beneficial effects:

[0015] 1. The wearer rotates the nut clockwise to rotate the threaded portion arranged at the end of the adjusting rod, so that the bottom end of the second connecting ear cooperates with the adjusting rod to slide, thereby reducing the spacing between the metal spring pieces. At the same time, the elastic force of the spring is used to make the second connecting ear cooperate with the nut to abut against the flat washer, thereby effectively preventing the nut from loosening. It can be used for wearers with a small head width. When the wearer's head width is large, the nut is rotated counterclockwise to increase the spacing between the metal spring pieces. By adjusting the spacing between the metal spring pieces and then adjusting the clamping force between the conductive rods, the comfort of the wearer's ears can be effectively guaranteed.

[0016] 2.

[0025] It should be noted that when the new stethoscope is in use, the wearer can adjust the spacing between the conduction rods 1 according to the width of the head according to the adjustment component. The wearer rotates the nut 10 clockwise to rotate the threaded portion 9 set at the end of the adjusting rod 8, so that the bottom end of the second connecting ear 7 cooperates with the adjusting rod 8 to slide, which can reduce the spacing between the metal spring pieces 5. At the same time, the elastic force of the spring 13 is used to make the second connecting ear 7 cooperate with the nut 10 to abut against the flat washer 12, thereby effectively preventing the nut 10 from loosening. It can be used for wearers with a small head width. When the wearer's head width is large, the nut 10 is rotated counterclockwise to increase the spacing between the metal spring pieces 5, and then the earplug 2 installed on the top of the conduction rod 1 is inserted into the ear hole, and the stethoscope head 4 is used to cooperate with the conduction hose 3 for auscultation, which can effectively ensure the comfort of the ear.
