Description

Pediatric stethoscope

Technical field

The present application relates to the technical field of medical devices, and more specifically, to a pediatric stethoscope.

Background technique

The stethoscope is the most commonly used diagnostic tool for gynecologists and pediatricians, and is the symbol of the doctor. Modern medicine began with the invention of the stethoscope. The shape and sound transmission method of the stethoscope have been continuously improved, but its basic structure has not changed much, mainly consisting of the sound pickup part. (chest piece), conductive part (hose) and listening part (ear piece). It usually consists of a stethoscope head, sound guide tube, and ear hook. It performs (frequency) non-linear amplification of the collected sound, and the connection between the auscultation head and the body is The larger the contact surface, the better the sound pickup effect. However, the surface of the human body has curvature. If the chest piece is too large, the listening head cannot fully contact the human body. Not only will the sound not be picked up well, but it will also leak out from the gap. Therefore, The size of the stethoscope head should be based on clinical needs. The diameter of the stethoscope chest piece is almost uniformly between 45 and 50 mm. For special cases, the diameter of the pediatric chest piece is generally 30 mm and that of newborns is 18 mm.

During the treatment of children, the doctor will use a stethoscope to auscultate the organs in the child's body. However, during the treatment of children, some children are not mentally mature enough and will be more resistant to treatment. Therefore, during the doctor's auscultation, the doctor Very resistant, twisting of body limbs will cause the doctor's stethoscope probe to be unable to be placed in the appropriate position, affecting the efficiency of auscultation, affecting the speed of diagnosis and treatment, and bringing great inconvenience to treatment. For this reason, we propose a pediatric stethoscope .

The bottom end of the probe 1 is fixedly connected to a sound guide tube 2, and the upper end of the right end of the sound guide tube 2 is fixedly connected to a The earhook 3 uses the probe 1, the sound guide tube 2 and the earhook 3 to enable the doctor to complete the auscultation work. It is convenient for the doctor to wear the earhook 3 on the outside of the ear, and conduct the earhook 3 through the cooperation of the probe 1 and the sound guide tube 2. To auscultate the internal organs of the patient, the right side of the probe 1 is fixedly connected to the connecting post 4. The axis of the finger cot 7 and the axis of the connecting post 4 are on the same horizontal line as the axis of the probe 1. The left side of the finger cot 7 The diameter value on the side is larger than the diameter value on the right side. The setting of the finger sleeve 7 serves to connect the probe 1 during use, making it convenient to use the connecting column 4 to control the position of the probe 1, and to facilitate the connection between the finger sleeve 7 and the connecting column 4 and the bearing. Cooperate so that the connecting column 4 moves in the inner cavity of the rotating sleeve 6 so that the position where the probe 1 is connected to the sound guide tube 2 is always at the bottom. The outside of the connecting column 4 is equipped with a rotating column 5 through a bearing. The connecting column 4 is located at the rotating position. Outside the axis of column 5, the diameter of the rotating column 5 is larger than the inner diameter on the right side of the rotating sleeve 6. The setting of the connecting column 4 and the eccentric rotating column 5 facilitates the rotation of the connecting column 4 around the axis of the rotating sleeve 6, thereby improving the connection. The detection range of column 4 prevents children from not cooperating with diagnosis and treatment, and can effectively improve the efficiency of auscultation. The external movable sleeve of rotating column 5 is equipped with a rotating sleeve 6. The right end of connecting column 4 is fixedly connected with a finger sleeve 7, and the external fixed installation of rotating sleeve 6 is There is a connecting rod 8, the index finger is inserted into the inside of the finger cot 7, and then the finger cot 7 is moved, and the finger cot 7 is used to drive the connecting column 4 and the probe 1 to rotate inside the rotating column 5, which facilitates the use of the device and facilitates the pairing of the finger cot 7 Probe 1 position for operation.

The inner cavity of the connecting rod 8 is movable with a threaded post 9. The inner side of the connecting suction cup 13 is located outside the probe 1.
