Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1: fig. 1 shows a method for processing data lines of a medical stethoscope, which comprises the following steps:
Step S100: wearing the stethoscope on a patient, correctly placing the auxiliary sensor at a position corresponding to the patient, collecting and analyzing the sound pressure value of the patient, and judging whether the stethoscope is normally used;
Step S200: after the normal use of the stethoscope is confirmed, physiological parameters and environmental parameters of a patient are collected through auxiliary sensors of the stethoscope, and the current auscultatable condition of the patient is comprehensively analyzed;
step S300: matching the current auscultatable condition of the patient with a preset condition, and presenting a corresponding prompting signal;
step S400: when judging that the current state of the patient is suitable for auscultation, starting remote auscultation recording, compressing recording data and then remotely sending the compressed recording data to a diagnostician terminal.
The step S100 specifically includes the following:
Listening to the patient's body sounds using a stethoscope is one of the important steps for a doctor to auscultate and diagnose, if the listening body sounds are below a threshold, some fine audio details may not be captured by the stethoscope, possibly resulting in missing important diagnostic information; these important audio features cannot be clearly heard, thus affecting the accurate diagnosis of the doctor, leading to erroneous diagnosis or delay, and negatively affecting the health of the patient, so ensuring moderate body tone intensity is one of the necessary conditions for effective auscultation and accurate diagnosis using a stethoscope.
Wearing a stethoscope on a patient, correctly placing an attached sensor of the stethoscope on a corresponding position of the patient, starting to collect a pressure value of sound to be detected of the patient, and obtaining the sound intensity to be detected through the pressure value of the sound to be detected, wherein the calculation formula is as follows: wherein Lp is the intensity of sound to be measured, p is the pressure value of the sound to be measured, and pref is the reference sound pressure value;
The pressure value of the sound to be measured requires the use of a sound sensor to measure the pressure change of the sound;
The sound intensity to be detected is used for reflecting the sound intensity to be detected of a stethoscope to monitor a patient, if the sound intensity to be detected is too small or too large, the stethoscope is not worn or debugged correctly, and the loss or attenuation of sound signals is caused, so that monitoring details cannot be accurately acquired, and further monitoring or diagnosis of the patient is affected;
Respectively comparing the sound intensity to be measured with a first threshold value and a second threshold value of the sound intensity to be measured, wherein the first threshold value of the sound intensity to be measured is smaller than the second threshold value of the sound intensity to be measured;
If the sound intensity to be measured is smaller than the sound intensity to be measured and is lower than the first threshold value or is larger than or equal to the second threshold value of the sound intensity to be measured, generating an incorrect use signal of the stethoscope and sending out an early warning prompt;
if the sound intensity to be measured is larger than the first threshold value of the sound intensity to be measured and smaller than or equal to the second threshold value of the sound intensity to be measured, generating a correct use signal of the stethoscope.
According to the invention, the sound intensity to be detected is obtained by collecting the pressure value of the sound to be detected of the patient, and the sound intensity to be detected is respectively compared with the first threshold value and the second threshold value of the sound intensity to be detected, and an incorrect use signal of the stethoscope or an correct use signal of the stethoscope is generated according to the comparison result, so that the stethoscope is ensured to obtain the real intensity of the body sound of the patient, the loss or attenuation of the sound signal caused by incorrect wearing or debugging is avoided, and the monitoring accuracy is improved.
The step S200 specifically includes the following:
After the stethoscope is correctly used, physiological parameters and environmental parameters of a patient are acquired through sensors attached to the stethoscope, wherein the physiological parameters comprise emotion stability indexes, and the environmental parameters comprise environmental comfort indexes.
The logic for obtaining the mood stabilization index is as follows:
a plurality of temperature sensors are respectively placed at different measuring positions corresponding to a patient, so that good contact with skin is ensured;
recording measurement data, recording the time when the skin temperature is lower than a reference skin temperature value at t time, and calculating the ratio between the time lower than the reference skin temperature value and the t time;
Wherein the reference skin temperature value is a skin temperature value measured in a quiet state;
Incorporating the ratios obtained by the plurality of temperature sensors into the same data set, calculating the average value of the data set, and marking the average value as an emotion stability index;
Placing a temperature sensor;
the temperature sensor 1 is placed on the patient's shoulder.
The temperature sensor 2 is placed on the neck of the patient.
The temperature sensor 3 is placed in the abdomen of the patient.
Recording temperature data;
reference skin temperature value: in the resting state, the skin temperature at each location was recorded, assuming a finger of 36.5 ℃, neck of 36.7 ℃, abdomen of 37.0 ℃.
The time interval t is set to 1 minute.
During the next 1 minute, the time at each location below the reference skin temperature value was recorded, assuming a reference skin temperature value of 37.1 ℃.
For example:
the time for which the finger temperature was below the reference skin temperature value (36.5 ℃) was 1 minute.
The time for which the neck temperature was below the reference skin temperature value (36.7 ℃) was 1 minute.
The time for which the abdominal temperature was lower than the reference skin temperature value (37.0 ℃) was 1 minute.
Calculating the ratio:
the ratio of the finger temperature below the reference skin temperature value is 1 minute/1 minute=1.
The ratio of neck temperature below the baseline skin temperature value is 1 minute/1 minute = 1.
The ratio of the abdominal temperature below the reference skin temperature value is 1 minute/1 minute=1.
Calculating an emotion stability index;
For example:
Data collection: [1,1,1]
Average value: (1+1+1)/3=1
Thus, the skin temperature stability index is 1;
The mood stabilization index is used for reflecting the mood stabilization degree of the patient, and the closer the mood stabilization index is to 1, the more stable the mood of the patient is; when the mood stabilization index is closer to 0, the whole skin temperature of the patient is higher than the reference skin temperature value, because the fluctuation and deterioration of the mood lead to the activation of an autonomic nervous system and further influence the regulation of the skin temperature, the patient is in a mood excited state, at this time, the heart rate and the respiration have corresponding changes, the rhythm of the heart is accelerated or irregular, the respiration becomes more rapid or different in depth, and further the contact and signal conduction between the stethoscope and the body surface are influenced, so that the monitored body sounds of the patient are not representative and the real body state of the patient is difficult to reflect, and therefore, when the electronic stethoscope is used for the patient remotely, the relevant signs of the mood and the like of the patient are very necessary to be included in auscultation.
The logic for obtaining the environmental comfort index is as follows:
Measuring the indoor air temperature Ta, using a temperature sensor or a thermometer and other devices to measure the indoor air temperature, ensuring that the sensor or instrument is placed in a typical human body activity area, and recording the obtained temperature value;
for example, measurements are taken at different locations in the room using a thermometer, resulting in the following data:
Position 1:22 DEG C
Position 2:23 DEG C
Position 3:21 DEG C
Position 4:22 DEG C
The metabolic heat production rate Hc of the human body, which refers to the heat produced in a resting state, is determined. Estimating the metabolic heat generation rate of the human body by using a formula or a reference standard value according to factors such as the weight, the age, the sex and the like of the individual;
Basal metabolic rate BMR refers to the minimum energy expenditure required by the human body to maintain normal physiological function in a quiet, non-motor, fasting, non-externally stimulated state. BMR can be estimated according to gender, age, height and weight, and common formulas include Harris-Benedict formulas;
harris-benect formula (applicable to adults):
male: bmr=66.5+ (13.75×weight kg) + (5.003×height cm) - (6.755 ×age)
Female: BMR= 655.1+ (9.563 ×weight kg) + (1.850×height cm) - (4.676 ×age)
Determining the heat radiation rate He of a human body;
The heat dissipation rate of the human body means that heat is dissipated to the surrounding environment by means of radiation and convection. According to the characteristics of the indoor environment, estimating the heat dissipation rate of the human body by using an empirical formula or a reference value;
for example, assume that the heat dissipation rate of a human body is 100 watts W in an indoor environment;
Determining the value of a constant K;
the constant K represents the weight of the human body to the heat sensitivity, and reflects the perception and reaction degree of the human body to the temperature change. The value of the constant K is usually between 0.5 and 1.0, and is adjusted according to the specific situation;
Calculating a value of an environmental comfort index;
According to the given formula: environmental comfort index=ta+ (Hc-He) ×k, and the numerical value obtained from the calculation result is substituted into the formula to perform calculation;
For example, assuming that the air temperature Ta is 22 ℃, the metabolic heat generation rate Hc of the human body is 80 watts, the heat radiation rate He of the human body is 100 watts, and the constant K is 0.7, the calculation is performed by substituting the formula:
PEI=22+(80-100)x0.7
PEI=22+(-20)x0.7
PEI=22-14
PEI=8
The environmental comfort index is used for evaluating the comfort level of the indoor environment; the larger the environmental comfort index, the higher the comfort level of the indoor environment; and the smaller the environmental comfort index, the lower the comfort level of the indoor environment;
in particular, a higher environmental comfort index generally means that parameters such as indoor environmental temperature and humidity are more similar to the thermal comfort requirements of the human body, so that the human body is more comfortable and satisfied. Conversely, a lower PEI value indicates that the indoor environment is more different from the thermal comfort requirements of the human body, possibly leading to discomfort, discomfort or even health problems.
If the environmental comfort index is higher, the heat load of the indoor environment is larger, and the human body needs to perform more heat adaptation and adjustment. This can lead to heat stress in the patient during auscultation, such as perspiration, discomfort and fatigue, and the body may increase efforts to dissipate heat, such as lowering body temperature through vasodilation and perspiration of the skin. These physiological regulation processes may affect physiological parameters such as blood pressure, heart rate, etc., thereby affecting auscultation results;
the emotion stability index and the environment comfort index are weighted and summed to obtain a patient stability coefficient;
for example, the patient stability factor may be obtained by the following calculation formula: Wherein PSI is patient stability factor, ESI is mood stability index, PEI is environmental comfort index,Preset proportional coefficients of patient stability coefficient and mood stability index respectively, andAre all greater than 0;
The patient stability coefficient is used for comprehensively evaluating the state stability degree of the patient during auscultation, the higher environment stability coefficient indicates that the overall state of the patient is stable and relaxed, the comfort level of the auscultation environment is proper, the patient is in a stable state at the moment, the body sounds of the auscultation patient are representative, and the body condition of the patient can be reflected remarkably; the lower patient stability coefficient indicates that the state of the patient and the environment in which the patient is positioned are not stable and comfortable enough to ensure that the patient cannot be in a stable state, and the auscultation of the body sounds of the patient is not representative at the moment, so that the auscultation process and the auscultation result are adversely affected;
The step S300 specifically includes the following:
Comparing the patient stability factor to a patient stability factor threshold;
If the patient stability coefficient is greater than or equal to the patient stability coefficient threshold, the patient is indicated to be in a stable and relaxed state, auscultation steps can be performed, and a stability signal is generated;
if the patient stability coefficient is smaller than the patient stability coefficient threshold, the patient state and the environment where the patient is positioned are not stable and comfortable enough, an adjusting signal is generated, an early warning prompt is sent out, and staff on a working site are prompted to improve auscultation environment and assist the patient in mood stabilization.
Under the condition of correctly using the stethoscope, the invention acquires the emotion stability index and the environment comfort index of the patient to acquire the patient stability coefficient, thereby being convenient for comprehensively evaluating the state stability degree of the patient, being capable of objectively knowing the emotion and the comfort degree of the patient in a specific environment, providing reference for the subsequent auscultation process, comparing the patient stability coefficient with the patient stability coefficient threshold value, being convenient for judging whether the state of the patient meets the auscultation requirement, being beneficial to improving the auscultation effect, reducing the interference factors and ensuring the comfort degree of the patient and the smooth progress of the auscultation process.

After the normal use of the stethoscope is confirmed, the parameter acquisition module acquires physiological parameters and environmental parameters of a patient through the auxiliary sensor of the stethoscope, comprehensively analyzes the current auscultatable condition of the patient, and sends the current auscultatable condition of the patient to the condition matching module;
