Description

Technical Field

[0001] The utility model relates to the technical field of auscultation equipment, in particular to a household auscultation equipment. Background Art

[0002] Auscultation equipment is a commonly used tool in the medical field to check the function and health of internal organs of the human body. Doctors judge the working conditions of various organs by listening to the sounds inside the patient's body. The stethoscope can be used to check the functions of organs such as the heart, lungs, and abdomen, helping doctors diagnose heart disease, lung disease, digestive system problems, etc. Auscultation equipment plays an important role in clinical diagnosis, helping doctors to detect patients' health problems in a timely manner and formulate corresponding treatment plans. Through the stethoscope, doctors can listen to the heart sounds of the heart, the breathing sounds of the lungs, the bowel sounds of the abdomen, etc., so as to understand the functional status of the organs and judge whether there are any abnormalities. Auscultation equipment is also widely used in medical fields such as emergency, internal medicine, and pediatrics. It is one of the important tools for doctors to diagnose diseases and monitor the health of patients.

[0003] Conventional auscultation methods include chest auscultation and back auscultation. Chest auscultation mainly obtains sound information from organs such as the heart. The auscultation sites of the back are at the posterior axillary line, above and below the scapular area, and inside and outside the subscapular area, symmetrically on both sides. Back auscultation mainly listens to lung breath sounds, so the two sides must be compared symmetrically. The breath sounds of the lungs are caused by the turbulence of the airflow when it enters the lungs, which produces vibrations, which can be heard through the chest wall and the stethoscope. The lung breath sounds auscultated from the back can help determine whether there are abnormalities in the breath sounds, which is of great significance for determining whether there is some inflammation in the lungs, or pleural effusion and obvious wheezing.

[0004] There are home stethoscope devices in the prior art, such as a home stethoscope with publication number CN113679414A, which performs rapid diagnosis by acquiring images of the patient's respiratory rate. However, for patients who use the device for self-use, back auscultation requires the stethoscope to be placed on the back, which is difficult to operate due to the limitation of arm length and is not easy to fit the back auscultation position, resulting in poor consistency in the acquired respiratory sounds and difficulty in accurately reflecting abnormal problems.

[0035] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figure 1-6 As shown, the household stethoscope device of the present invention comprises an upper body 1 , a lower body 2 and a stethoscope probe 3 .

[0037] The upper body 1 is arranged in a long strip shape, and the upper body 1 includes a mating surface 101 and an installation surface 102. The mating surface 101 and the installation surface 102 are respectively located on both sides of the upper body 1. Specifically, the upper body 1 is arranged in a flat strip shape, and its exterior is a plastic shell. Both ends of the plastic shell in the length direction are rounded, and rounded corners are set at the corners of the plastic shell to facilitate users to take it. The mating surface 101 and the installation surface 102 are respectively the two largest planes on the exterior of the upper body 1, that is, they are respectively located on both sides of the thickness direction of the upper body 1.

[0038] The lower body 2 is arranged on the upper body 1 and is electrically connected to the upper body 1. A sliding surface 203 is arranged on the lower body 2. The matching surface 101 of the upper body 1 contacts the sliding surface 203. The upper body 1 is slidably arranged on the sliding surface 203 of the lower body 2 through the matching surface 101, so that the upper body 1 can be slid and unfolded on the lower body 2. The specific sliding and unfolding direction is the length direction of the upper body 1. After the upper body 1 is slid and unfolded on the lower body 2, the overall length of the device increases, and the user can hold the lower body 2 for operation. Through the extended length of the upper body 1, the distance that the user's arm cannot reach the back position is compensated, so that the user can hold it stably and collect cardiopulmonary breathing sounds from the back.

[0039] When the user is performing chest auscultation, the upper body 1 is slid and folded onto the lower body 2, and the upper body 1 and the lower body 2 can be held in the hand and placed on the chest for auscultation. The flat setting of the upper body 1 and the lower body 2 is more convenient for the user to hold the device after folding.

[0040] The mating surface 101 and the sliding surface 203 can slide relative to each other. In specific settings, the mating surface 101 and the sliding surface 203 can be selected to be contact sliding or non-contact sliding. Contact sliding has better stability. In this embodiment, the mating surface 101 and the sliding surface 203 are connected by contact sliding.

[0041] The stethoscope probe 3 is fixed on the mounting surface 102 of the upper body 1. The stethoscope probe 3 is used to collect vibration signals of the detected part. The overall shape of the stethoscope probe 3 is pie-shaped. When collecting the vibration signals of the user's body, contact collection is preferred. The signals received by this collection method are more accurate, and there will be no problem of different sound sizes caused by inconsistent distances.

[0042] In addition, in the upper body 1, devices such as amplifiers and filters need to be set up. The stethoscope probe 3 collects the vibration signal and converts it into an electrical signal and transmits it to the upper body 1. After amplification and filtering by the upper body 1, it is transmitted to the lower body 2. The lower body 2 performs digital-to-analog conversion and completes data transmission and comparison to achieve data visualization and backup. A display screen 6 is set on the side of the lower body 2 away from the sliding surface 203. The display screen 6 can be used to set the timing and other settings, and display the collected data such as breathing sounds.

[0043] In this embodiment, in order to allow the upper body 1 and the lower body 2 to slide relative to each other, at least two limit members 4 are provided, one end of the limit member 4 is fixed on the mating surface 101 of the upper body 1, and the other end extends to the sliding surface 203 to limit the upper body 1 from sliding on the sliding surface 203 of the lower body 2. Specifically, the number of the limit members 4 is set to two, and they are mirror images of each other in the sliding direction of the upper body 1. The two limit members 4 can ensure the sliding stability of the upper body 1 and the lower body 2, and will not separate during the sliding process.

[0044] In order to cooperate with the limiting member 4, a dovetail groove 201 is opened on the sliding surface 203 of the lower body 2, and the limiting member 4 extends into the dovetail groove 201 and is adapted to the dovetail groove 201. The limiting member 4 is slidably connected to the lower body 2 through the dovetail groove 201. Accordingly, the limiting member 4 is configured to be dovetail-shaped, and the specifications are the same as those of the dovetail groove 201. The number of dovetail grooves 201 is also set to two, and corresponds one to one with the two limiting members 4, so that the limiting member 4 can stably slide in the dovetail groove 201. At the same time, the narrow upper and wide lower setting of the dovetail groove 201 also makes it impossible for the limiting member 4 to separate from the dovetail groove 201.

[0045] As a preferred embodiment, in order to ensure that the upper body 1 and the lower body 2 can be stably electrically connected during the sliding process, a flexible cable 5 is also provided. One end of the flexible cable 5 is electrically connected to the upper body 1, and the other end is electrically connected to the lower body 2. The flexible cable 5 is used to electrically connect the upper body 1 and the lower body 2.

[0046] When the upper body 1 slides, the flexible cable 5 can adaptively adjust the lengths of the two ends of the bent portion by changing the position of the bent portion to adapt to the change in the relative position of the upper body 1 and the lower body 2, thereby achieving a stable line connection. Specifically, the flexible cable 5 can use an FPC soft cable to transmit electrical signals and supply power to the upper body 1.

[0047] Correspondingly, a wire groove 202 is opened on the sliding surface 203 of the lower body 2, and the length direction of the wire groove 202 is the same as the sliding direction of the upper body 1. The flexible cable 5 extends into the wire groove 202. The wire groove 202 is used to accommodate the flexible cable 5 and leave deformation space for the flexible cable 5 when the upper body 1 slides.

[0048] The wire groove 202 can accommodate the flexible flat cable 5. After the upper body 1 is fully unfolded, the flexible flat cable 5 is protected to prevent the user from touching the flexible flat cable when holding the lower body 2 and causing damage to the line. At the same time, the wire groove 202 arranged on the sliding surface 203 has a lower molding difficulty and is convenient for production and manufacturing.

[0049] In this embodiment, the stethoscope probe 3 includes a shell 31, a diaphragm 32 and an electroacoustic transducer 33. The shell 31 is fixed on the mounting surface 102 of the upper body 1. A cavity is provided in the shell 31, and the side of the shell 31 away from the mounting surface 102 is open. The diaphragm 32 is fixed on the shell 31 and is located on the open side of the shell 31. The electroacoustic transducer 33 is fixed in the cavity of the shell 31, and the electroacoustic transducer 33 is used to convert sound signals into electrical signals.

[0050] The diaphragm 32 is used to receive external vibration signals. The cavity set on the shell 31 can resonate with the diaphragm 32 through the internal air, and feed the vibration signal back to the electroacoustic transducer 33. The electroacoustic transducer 33 can specifically be a microphone. After the sound signal is converted into an electrical signal by the electroacoustic transducer 33, it is processed and transmitted to the lower body 2.

[0051] In addition, the stethoscope probe 3 and the limiter 4 are respectively arranged on the two ends of the upper body 1, that is, in addition to being located on the mounting surface 102 and the mating surface 101 respectively, the stethoscope probe 3 and the limiter 4 are also respectively arranged on the two ends in the length direction of the upper body 1, so that after the upper body 1 is slid and unfolded, the length of the upper body 1 can be maximized for distance compensation.

[0052] In this embodiment, the lower body 2 includes an outer shell 21 and a circuit board 22. The outer shell 21 is slidably connected to the upper body 1. The sliding surface 203 is arranged on the outer shell 21. The circuit board 22 is fixed in the outer shell 21. The circuit board 22 is electrically connected to the upper body 1. The analog signal at the output end of the electroacoustic transducer 33 is converted into a digital signal through the arranged circuit board 22, and is sent to the user's mobile phone or the Internet through the communication circuit arranged on the circuit board 22. The communication circuit can select a Bluetooth module, a 4G module or a 5G module.

[0053] The shell 31 is made of the same material as the plastic shell of the upper body 1 and has the same shape and size as the plastic shell of the upper body 1, so that after the upper body 1 is folded, it can completely overlap with the lower body 2 through the matching surface 101 and the sliding surface 203, making it more convenient for users to carry and hold.

[0054] In this embodiment, a type-c charging port is provided on the outer shell 21, and the lower body 2 also includes a battery 23, which is fixed in the outer shell 21 and electrically connected to the circuit board 22. The battery 23 is used to power the circuit board 22, and the battery 23 can be charged through the type-c charging port on the outer shell 21 to facilitate the carrying and use of the device.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
