Description

Intelligent stethoscope for internal medicine

Technical Field

The invention belongs to the field of stethoscopes, and particularly relates to an intelligent stethoscope for internal medicine.

Background

Heart sounds and respiratory sounds are physiological characteristics produced in the movement of the human heart and in the respiratory movement of the human body, which contain physiological and pathological information of the heart and respiratory system. The stethoscope is only innovated in hardware links in the development process of electronics, and the stethoscope is in the form that an electronic microphone receives sound and then filters, operational amplification, stores and the like of various electronic hardware, so that the functions of generating digital files, storing and repeatedly playing are realized by recording auscultation sound information. The purpose is to make the signals of the heart sounds and the respiratory sounds more clear and accurate, but because the interference noise of the sounds of the heart sounds and the respiratory sounds is overlapped with the signals in frequency spectrum, the interference noise cannot be effectively eliminated by adopting a common hardware function, and more effective signal processing technology is required to eliminate the interference noise, so that the traditional electronic stethoscope cannot really assist doctors in clinical diagnosis.

The patent with Chinese patent publication number CN102697520B discloses an electronic stethoscope for assisting diagnosis, which is used for intelligently identifying physiological parameters such as heart sounds and breath sounds, distinguishing the types of the heart sounds and the breath sounds and extracting disease characteristics. The system comprises a processor unit, a signal acquisition unit, a peripheral driving unit, a storage unit and a data bus interface unit, wherein the signal acquisition unit is connected with the processor unit, the signal acquisition unit acquires heart sound and breath sound signals and performs pre-processing on the heart sound and the breath sound signals, the processor unit specifically realizes a pattern recognition algorithm for the heart sound and the breath sound, separates the heart sound and the breath sound signals, completes intelligent recognition and classification of the heart sound and the breath sound signals, and manages other hardware units; the storage unit is used for storing the program and the extension program thereof, storing heart sound breathing sound data, standard heart sound and breathing sound, and hearing sound patterns of typical cases of diseases and outputting and playing; the peripheral driving unit and the data bus interface unit are used for realizing peripheral operation function driving and data communication.

The stethoscope has the advantages of high accuracy, easy operation, convenient carrying, rapid diagnosis and intelligent identification, and assists doctors in auscultation. However, because of use in a clinical setting, stethoscopes may contact multiple patients, with the risk of cross-infection. Even with the disinfection measures, there is still a need to ensure that all parts of the stethoscope can be thoroughly cleaned and disinfected to prevent pathogen transmission. And although the processor unit has a pattern recognition algorithm, there may be problems with signal noise, interference or variations in some cases, which may affect the performance and accuracy of the algorithm. Signal optimization and noise suppression may require additional techniques and algorithms to cope with complex clinical situations.

The manner in which the sound transmission medium affects the sound quality is complex and diverse. The water quantity carried by the articles is different, and the sound generated during knocking can also change, for example, the glass is filled with water with different components, and the cup is knocked to generate different sounds. Different media can affect the propagation speed of sound, the frequency response, and the color of sound. For example, sound traveling in air may be affected by humidity, temperature, and air pressure, while sound traveling in a solid or liquid is affected by the density and elasticity of the medium. Therefore, this scheme has proposed an intelligent stethoscope for internal medicine.

Disclosure of Invention

In order to solve the problems, the invention provides the intelligent stethoscope for the medical department, which solves the limitations of the traditional stethoscope in terms of sanitation, signal optimization and data analysis, improves the auscultation effect and quality, and provides more accurate, convenient, safe and intelligent auscultation experience for doctors.

In order to achieve the above object, the technical scheme of the present invention is as follows: an intelligent stethoscope for medical department, comprising

The hearing head assembly is used for being close to a patient and acquiring heartbeat sound signals; an auxiliary hearing assembly is magnetically attracted to one side of the hearing head assembly, and the auxiliary hearing assembly is used for acquiring breathing sound signals; the inside of the listening head component is fixedly connected with an ultrasonic sensor, an amplifier and a digital signal processor;

the processing component is used for processing the heartbeat sound signal and the breathing sound signal and carrying out noise precipitation, classification extraction and standard pattern comparison;

the intelligent disinfection component is used for spraying disinfectant to the auditory head component for disinfection after the auditory head component is attached to the skin; and utilizes disinfectant to assist in sound transmission;

the water detection assembly is used for monitoring the residual quantity of the disinfectant on the head assembly and comprises a knocking piece and a sound wave sensor, the knocking piece and the sound wave sensor are both arranged in the head assembly, and the sound wave sensor acquires the difference relation between the presence and absence of water on the head assembly through the sound wave characteristics acquired by knocking the head assembly to form a correction coefficient and acquire the residual quantity of the disinfectant on the head assembly;

the processing component is also used for carrying out signal correction through the residual quantity of the disinfectant on the hearing head component, when carrying out signal correction, the received sound signal is corrected according to the measured water quantity by utilizing a correction algorithm, and the gain, the frequency characteristic or the phase of the signal is adjusted according to the change of the water quantity by the correction algorithm.

The principle and the beneficial effect of the scheme are adopted: the stethoscope not only can acquire heartbeat sound signals, but also can acquire breathing sound signals through the auxiliary hearing assembly, so that more comprehensive physiological information is provided for doctors, and the stethoscope is helpful for diagnosing the condition of patients more accurately. Noise precipitation, classification extraction and standard pattern comparison functions of the processing assembly are beneficial to filtering noise, so that a doctor can more clearly distinguish heartbeat sound and respiratory sound, and auscultation accuracy is improved.

The intelligent disinfection component enables the stethoscope head component to disinfect, reduces the risk of cross infection and improves the sanitary safety of the stethoscope. Meanwhile, the stethoscope can directly contact the skin to auscultate by utilizing the disinfectant to assist the sound transmission, so that the interference of clothes on auscultation is avoided, and the tone quality of sound received by the stethoscope is improved. Because the common stethoscope can hear the sound with the frequency ranging from 20 Hz to 20000 Hz, the transmission effect of the sound between the stethoscope head and the skin can be improved by utilizing the disinfectant to assist the sound transmission, the signal transmission efficiency and the fitting degree of the stethoscope are improved, the stethoscope can receive partial infrasonic waves which cannot be heard by the common stethoscope, and the sound with lower frequency can be heard, thereby doctors can evaluate the health condition of patients more comprehensively, and abnormal conditions can be detected more easily.

When the moisture detection assembly is used for monitoring the residual quantity of the disinfectant, the moisture detection assembly is used for obtaining the difference value relation between the presence and absence of water on the head assembly through knocking the sound wave characteristics obtained by the head assembly, so that a correction coefficient is formed, and the residual quantity of the disinfectant on the head assembly is obtained. The sound signal is corrected by a correction algorithm in combination with the residual quantity of the disinfectant on the auditory head assembly, so that the accuracy and the reliability of the signal are improved, wherein a correlation model can be established by utilizing the correlation between the quantity of the transmission medium and the sound quality. According to the change of the residual quantity of the disinfectant, the processing component can automatically adjust the parameters of the sound signals, adapt to different auscultation conditions and environments, and improve the adaptability and the flexibility.

Therefore, the intelligent stethoscope for internal medicine uses residual disinfectant to disinfect the stethoscope head assembly by combining innovative functions, improves the sanitary safety of the stethoscope, solves the limitations of the traditional stethoscope in terms of sanitation, signal optimization and data analysis, improves the auscultation effect and quality, and provides more accurate, convenient, safe and intelligent auscultation experience for doctors.

Such varied selection accommodates the preferences and clinical needs of different doctors.

When the ultrasonic sensor is used for acquiring the heartbeat sound signal, the digital signal is directly transmitted to the earphone, so that the problem of signal attenuation possibly occurring due to sound conduction loss in the traditional stethoscope is avoided, and clearer and accurate auscultation experience is provided. By turning off the headphones, the heart sounds are directly captured using the long tube and earplugs, the physician can experience an original auscultation sensation similar to that of a conventional stethoscope, which helps to better capture the heart sound details in some special cases.

The doctor can flexibly select different auscultation modes according to the condition and clinical requirements of the patient, so that the convenience and the flexibility of use are improved. By switching between different auscultation modes, doctors can compare the difference of different auscultation signals in real time, verify the accuracy of diagnosis and are beneficial to more accurate clinical judgment. For different patients, different body positions or different environments, a doctor can select the most suitable auscultation mode according to the situation so as to obtain the best auscultation effect.
