Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intelligent stethoscope with improved efficiency. Background Art

[0002] A stethoscope is an important auxiliary tool for clinicians in diagnosing diseases of the heart, lungs, and other organs, and in understanding a patient's condition. It is also an important standard for assessing illness. A stethoscope primarily relies on the doctor's experience and hearing to interpret sound signals. However, in some complex situations, especially for beginners or non-specialist doctors, accurately locating the optimal auscultation point and distinguishing different physiological sounds can be challenging. Therefore, digital stethoscopes have emerged on the market. By integrating sensors and a display screen, they can analyze physiological signals to a certain extent and provide feedback to doctors, helping less experienced doctors to quickly diagnose or differentiate conditions.

[0003] However, most of these devices can only provide a simple digital display of heart rate or audio signals. During auscultation, doctors often need to repeatedly move the stethoscope to multiple locations on the patient's body to find the area with the loudest sound and clearest signal. This cannot effectively solve the errors caused by manual operation during auscultation, which not only increases the workload of doctors but may also lead to misdiagnosis of the condition due to improper selection of auscultation points. Utility Model Content

[0004] This invention provides an efficient intelligent stethoscope to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An efficiency-enhancing intelligent stethoscope includes a stethoscope head, a sound tube, and an ear tube. The stethoscope head is connected to the ear tube via the sound tube. An observation component is disposed between the stethoscope head and the sound tube. The stethoscope head contains a control unit, a heart sound sensor, and multiple miniature volume sensors. The control unit is connected to the heart sound sensor and the multiple miniature volume sensors respectively. The multiple miniature volume sensors are evenly arranged around the stethoscope head. Multiple LED indicator lights are arranged around the back edge of the stethoscope head. The multiple miniature volume sensors and the multiple LED indicator lights are respectively connected to each other. A monitoring display screen for displaying heart rate is disposed on the observation component. The monitoring display screen is electrically connected to the heart sound sensor via the control unit.

[0007] Furthermore, the observation component is connected to the stethoscope head via a shaped flexible tube. This tube enhances operational flexibility, allowing doctors to adjust it according to different operating environments and ensuring that measurements are not inaccurate due to positional movement during testing. It also allows for more flexible adjustment of the stethoscope's angle and position during operation, enabling accurate acquisition of the patient's heart or lung sounds, while keeping the display and operation sections of the observation component easily viewable and usable.

[0008] Furthermore, the LED indicator has three colors, each triggered based on a different threshold. Each miniature volume sensor generates a different audio signal by acquiring the sound intensity in the corresponding direction. When multiple LED indicators simultaneously display the corresponding color, the doctor can move the stethoscope towards the side of the LED indicator with the stronger volume to obtain the heart rate closer to the source of the heart.

[0009] Furthermore, the hearing head is also equipped with a respiratory sound sensor for monitoring abnormal breathing in patients, and the respiratory sound sensor is connected to the control unit.

[0010] Furthermore, the observation component includes a housing, a power supply, and a buzzer. Both the power supply and the buzzer are housed within the housing, which has a sound amplification port for the buzzer to transmit sound. When the heart sound sensor detects an abnormal heart rate, the buzzer will sound to alert the doctor to the patient's abnormal heart rate. The buzzer is controlled by a control unit; when the heart rate exceeds a preset normal range, the buzzer will trigger an alarm.

[0011] Furthermore, the outer shell is designed with a streamlined structure that facilitates gripping. This streamlined structure makes it easier for doctors to grip the device during operation, ensuring improved stability and controllability of the stethoscope during listening procedures.

[0012] Furthermore, the observation component is also equipped with control buttons connected to the monitoring display screen. The control buttons can be used to select different monitoring modes. The control buttons are connected to the monitoring display screen via a circuit. When a doctor presses a button, the button triggers a corresponding electrical signal that is transmitted to the control unit. Upon receiving the signal, the control unit executes the corresponding operation, updating the content or functional status of the display screen.

[0013] Furthermore, the observation assembly also includes a control switch connected to a power supply. The power supply provides power to the entire observation assembly, ensuring the normal operation of components such as the buzzer and monitoring display screen. The power supply uses a rechargeable battery to guarantee continuous operation of the equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the cooperation of the observation component and the heart sound sensor, senses the range of the patient's heart rate and issues an abnormal alarm when it reaches a preset threshold, which can help doctors quickly diagnose the condition, reduce the chance of misjudgment, and improve diagnostic efficiency.

[0016] 2. This utility model automatically senses volume differences from different directions through a miniature volume sensor and provides real-time feedback on the volume strength and position through a visual LED indicator, which can help doctors quickly locate the best auscultation point. This can more accurately locate the target sound source and thus improve the quality of diagnosis.

[0017] 3. This utility model reduces the size of the stethoscope by separating the observation component from the stethoscope, and at the same time makes it easier to grasp the observation component during auscultation, thereby improving the stability and fit of the stethoscope and reducing measurement errors caused by manual operation.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0022] Example 1

[0023] like Figure 1 and 2 As shown, this utility model discloses an efficiency-enhancing intelligent stethoscope, including a stethoscope head 1, a sound tube 2, and an ear tube 3. The stethoscope head 1 is connected to the ear tube 3 through the sound tube 2. An observation component 4 is disposed between the stethoscope head 1 and the sound tube 2. The stethoscope head 1 is equipped with a control unit, a heart sound sensor, and multiple miniature volume sensors. The control unit is connected to the heart sound sensor and the multiple miniature volume sensors respectively. The multiple miniature volume sensors are evenly arranged around the stethoscope head 1. Multiple LED indicator lights 5 are arranged around the back edge of the stethoscope head 1. The multiple miniature volume sensors and the multiple LED indicator lights 5 are respectively connected to each other. A monitoring display screen 6 for displaying heart rate is disposed on the observation component 4. The monitoring display screen 6 is electrically connected to the heart sound sensor through the control unit.

[0024] The observation component 4 is connected to the stethoscope head 1 via a flexible tubing 7. Specifically, the flexible tubing 7 enhances operational flexibility, allowing doctors to adjust it according to different operating environments and ensuring that measurements are not inaccurate due to positional movement during testing. It allows for more flexible adjustment of the stethoscope's angle and position during operation to accurately acquire the patient's heart or lung sounds, while keeping the display and operation sections of the observation component 4 easily viewable and usable.

[0025] The LED indicator 5 has three colors, each triggered by a different threshold. Specifically, each miniature volume sensor generates a different audio signal by collecting sound intensity from a corresponding direction. In this application, the LED indicator 5 is set to red when the monitored volume is less than 40dB, yellow when the monitored volume is between 40dB and 60dB, and green when the monitored volume is greater than 60dB. The green LED indicator 5 indicates a volume of 60dB or higher, suggesting a strong heart sound signal, and the doctor can consider measuring the data at this location. The yellow LED indicator 5 indicates a volume between 40-60dB, suggesting a moderate volume level, which can be considered for measurement, but may not be the optimal point. The red LED indicator 5 indicates a volume below 40dB, suggesting a weak heart sound, requiring further movement of the stethoscope 1 to find a stronger signal. When multiple LED indicators 5 simultaneously display their corresponding colors, the doctor can move the stethoscope 1 towards the green LED indicator 5 to obtain a measurement point closer to the heart source.

[0026] The listening head 1 is also equipped with a respiratory sound sensor for monitoring abnormal patient breathing, which is connected to the control unit. The respiratory sound sensor uses sound pattern recognition technology to analyze the data collected and determine whether abnormal respiratory sounds, such as dry rales, wet rales, or wheezing, are present. When abnormal respiratory sounds are detected, the monitoring display screen 6 shows the abnormality category, and a buzzer sounds an alarm when a threshold sound is detected.

[0027] The observation component 4 includes a housing, a power supply, and a buzzer. Both the power supply and the buzzer are housed within the housing, which has a sound amplification port for the buzzer to transmit sound. Specifically, when the heart sound sensor detects an abnormal heart rate, the buzzer will sound to alert the doctor to the patient's abnormal heart rate. The buzzer is controlled by a control unit; when the heart rate exceeds a preset normal range, the buzzer will trigger an alarm.

[0028] The control unit is pre-set with a threshold range for receiving heart rate signals from the heart sound sensor. This threshold range triggers a buzzer when the heart rate is below 60 beats per minute or above 100 beats per minute. Specifically, according to medical standards, the normal heart rate range for adults is typically 60 to 100 beats per minute. Therefore, the heart rate threshold can be set so that the buzzer sounds an alarm when the heart rate is below 60 beats per minute (low heart rate) or above 100 beats per minute (high heart rate). The control unit digitizes the physiological signals collected by the heart sound sensor to calculate real-time heart rate data. Using a Fast Fourier Transform (FFT) algorithm, background noise and interference signals are filtered out to extract stable heart rate information. The control unit compares the real-time calculated heart rate data with the pre-set threshold range. If the heart rate exceeds the set normal range, the control unit sends a signal to activate the buzzer and trigger an alarm.

[0029] The outer shell is designed with a streamlined structure that facilitates gripping. Specifically, the streamlined structure facilitates gripping during operation, ensuring improved stability and controllability of the auditory head 1 during the listening procedure.

[0030] The observation component 4 is also equipped with control buttons 8 connected to the monitoring display screen 6. Specifically, control buttons 8 can be used to select different monitoring modes, such as switching between heart rate monitoring, volume detection, or other diagnostic modes, allowing doctors to adjust the device's functions as needed. Control buttons 8 are connected to the monitoring display screen 6 via a circuit. When a doctor presses a button, the button triggers a corresponding electrical signal that is transmitted to the control unit. After receiving the signal, the control unit executes the corresponding operation, updating the content or functional status of the display screen.

[0031] The observation component 4 is also equipped with a control switch connected to the power supply. Specifically, the power supply provides power to the entire observation component 4, ensuring the normal operation of components such as the buzzer and the monitoring display screen 6. The power supply uses a rechargeable battery to ensure continuous use of the equipment.

[0032] Example 2

[0033] Based on Example 1, this example proposes a specific implementation process for an efficiency-enhancing intelligent stethoscope.

[0034] The specific implementation principle and process are as follows:

[0035] This application solution uses a built-in heart rate sensor to monitor the patient's heart rate data in real time and converts it into electrical signals, which are then transmitted to the control unit. The control unit digitizes the received heart rate data and extracts stable heart rate information. Doctors can view the patient's heart rate data in real time on the monitoring display screen 6 on the observation component 4. When the patient's heart rate exceeds a preset threshold range, the control unit will trigger a buzzer to sound an alarm, alerting the doctor to the abnormal heart rate and allowing for timely intervention, thus achieving intelligent operation.

[0036] Multiple miniature volume sensors are evenly distributed around the stethoscope 1. Each sensor is responsible for collecting heart sound signals from different directions and converting them into electrical signals, which are then transmitted to the control unit for analysis. The control unit uses corresponding LED indicator lights 5 to indicate the sound intensity from each direction. If the volume is strong in a certain direction, the LED indicator light 5 will trigger the corresponding color according to a preset threshold range. When the volume is below 40dB, the LED indicator light 5 is red, indicating that the heart sound is weak at that location. When the volume is between 40dB and 60dB, the LED indicator light 5 is yellow, indicating that the volume is moderate. When the volume is above 60dB, the LED indicator light 5 will be green, indicating to the doctor that this direction may be the location with the strongest heart sound signal. The doctor can further adjust the position of the stethoscope 1 based on the direction of the green LED light to accurately locate the optimal measurement point.

[0037] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
