[0001] The present invention relates to the technical field of health management systems, and in particular to a respiratory monitor and a nursing monitoring device. Background Art

[0002] In modern medicine, monitoring of respiratory status is an important part of assessing patients' vital signs and health status. Traditionally, clinicians mainly rely on equipment such as ECG monitors and stethoscopes to monitor patients' respiratory rate and amplitude.

[0003] The ECG monitors currently used in clinical practice measure the respiratory rate and amplitude through the change in the resistance difference between the ECG electrodes at different parts of the chest. This method also has limitations, mainly affected by various factors such as patient movement, body position changes, and electrode position stability, and often results in inaccurate measurements. Ordinary stethoscopes can only listen to respiratory sounds intermittently, and cannot provide real-time, continuous monitoring and visualization of respiratory sound data. In addition, differences in doctors' hearing and technical levels also cause subjectivity and inconsistency in judgment.

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] Embodiment 1:

[0045] An embodiment of the present invention provides a respiratory monitor, such as Figure 1 As shown, including:

[0046] The sound pickup tube 101 is tied to the patient's throat and is used to collect the patient's breathing sounds;

[0047] The converter 102 is used to sense the breathing sound, convert the breathing sound into an electrical signal, analyze and process the electrical signal, and obtain a real-time monitoring waveform;

[0048] A monitoring interface module 103, one end of which is connected to the converter 102 via a cable, and the other end of which is connected to the monitor 104, for transmitting the real-time monitoring waveform to the monitor 104;

[0049] The monitor 104 is used to display the monitoring waveform to show the patient's respiratory rate and respiratory pattern.

[0050] In a specific embodiment, Figure 2 As shown, the pickup tube is similar to the structure of a traditional stethoscope head and is used as a device for continuously collecting the patient's breathing status. Specifically, it includes:

[0051] The sound pickup cavity 201 is used to capture the patient's breathing sounds, specifically, to capture the patient's breathing sounds when the patient is in a resting state. The sound pickup cavity 201 has good acoustic characteristics and can capture not only low-frequency breathing sounds but also medium-frequency breathing sounds.

[0052] The acoustic conduction tube 202 is connected to the sound pickup cavity 201 and is used to transmit the respiratory sound through the airway.

[0053] The acoustic transmission tube 202 is a hollow rubber tube. By selecting a soft rubber tube material, the comfort during use can be ensured while avoiding sound distortion. The clear conduction of the acoustic transmission tube 202 can ensure the accuracy of subsequent signals.

[0054] The binding 203 is connected to the sound pickup cavity 201 and is used to fix the sound pickup cavity 201 to the patient's throat. The binding 203 not only fixes the sound pickup cavity 201, but also makes the sound pickup cavity 201 close to the patient's throat, thereby making the patient's breathing sounds collected by the sound pickup cavity 201 clearer.

[0055] The pickup tube 101 optimizes the acoustic performance and can effectively capture the weak breathing sounds in the throat. Compared with the traditional monitoring method, it can obtain more accurate breathing signals and reduce the occurrence of errors.

[0056] The converter 102 comprises:

[0057] The sound pickup diaphragm is used to sense the vibration of the sound waves of the breathing sound. The sound pickup diaphragm is a sensitive element of the converter 102 and can sense the vibration of the sound waves.

[0058] The signal processing circuit is used to convert the sound wave vibration into an electrical signal, analyze the parameters of the electrical signal, extract the frequency characteristics, amplitude characteristics and pattern characteristics of the electrical signal, and form a real-time monitoring waveform based on the frequency characteristics, amplitude characteristics and pattern characteristics.

[0059] First, after the sound pickup diaphragm senses the sound wave vibration of the breathing sound, the sound pickup diaphragm also vibrates accordingly, causing the magnetic field in the surrounding electromagnetic induction coil to change accordingly. The changing magnetic field causes an induced electromotive force inside the coil, which will change according to the characteristics of the breathing sound, thereby forming a changing electrical signal, thereby converting the breathing sound into an electrical signal.

[0060] Next, the signal processing circuit can also analyze the parameters of the electrical signal to extract the frequency characteristics, amplitude characteristics and pattern characteristics of the electrical signal.

[0061] Then, a real-time monitoring waveform is formed according to the frequency characteristics, amplitude characteristics and pattern characteristics of the electrical signal.

[0062] Specifically, the signal processing circuit determines the distribution of the expiratory phase and the inspiratory phase based on the pattern characteristics of the electrical signal. For example, the positive direction signal of the electrical signal is the expiratory phase, and the negative direction signal is the inspiratory phase, thereby determining the distribution of the expiratory phase and the inspiratory phase. Based on the frequency characteristics of the electrical signal, the adjacent intervals of the expiratory phase and the inspiratory phase are determined, for example, the time interval between the positive direction signal and the negative direction signal of the electrical signal and the next positive direction signal and negative direction signal, thereby determining the adjacent intervals of the expiratory phase and the inspiratory phase. Based on the amplitude characteristics of the electrical signal, the peak value of the expiratory phase and the peak value of the inspiratory phase are determined, for example, the maximum value of the positive direction signal of the electrical signal and the maximum value of the negative direction signal. In this way, the overall direction and speed of change of the waveform are determined, and the final real-time monitoring waveform is formed by connecting these characteristic points.

[0063] The signal processing circuit is also used to pre-process the electrical signal to obtain a pre-processed signal, filter the pre-processed signal and amplify the signal to ensure signal quality and facilitate subsequent signal analysis. During the pre-processing process, redundant signals and abnormal signals are deleted, and missed signals are supplemented.

[0064] The converter 102 provides clinical medical staff with a comprehensive respiratory status assessment reference through multi-dimensional information, thereby improving the accuracy of judgment.

[0065] The monitoring interface module 103 includes:

[0066] An input interface, connected to the converter 102 via a cable, for receiving a real-time monitoring waveform;

[0067] The output interface is designed based on the shape of the socket of the monitor 104 and is plugged into the socket of the monitor 104 to transmit the real-time monitoring waveform to the monitor 104 .

[0068] The monitoring interface module 103 is mainly used to realize the switching between the converter 102 and the monitor 104, which is not only a physical connection but also a signal matching.

[0069] Through the standardized monitoring interface module 103, it can be easily integrated with existing monitors, reducing the complexity of retraining medical staff in a new medical environment, making the operation simpler and more effective.

[0070] Finally, the monitor 104 includes: a display screen for displaying real-time monitoring waveforms.

[0071] Specifically, the real-time monitoring waveform includes the respiratory rate and respiratory pattern. Figure 3 The bottom layer is a respiratory waveform display area 301, with the exhalation phase 302 in the front and the inhalation phase 303 in the back, and the number corresponding to the respiratory frequency 304 at the end.

[0072] The monitor 104 presents more intuitive graphics in a visual manner, which helps to quickly identify abnormalities.

[0073] By displaying it to clinical medical staff in waveform and digital form, it can help medical staff quickly determine the patient's respiratory status.

[0074] Through real-time continuous monitoring and accurate analysis of the patient's respiratory status, the work efficiency of clinical medical staff is greatly improved and the monitoring risk of critically ill patients or surgical patients is reduced.

[0075] The respiratory monitor can provide accurate and timely respiratory monitoring information, greatly reducing the probability of medical accidents and improving the efficiency of medical staff in patient care. Faster response time and accurate information can provide patients with safer and more effective care.

[0076] One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0081] A finger pulse oxygen saturation detector 402, used to collect the patient's blood oxygen saturation;

[0082] The respiratory monitor 403 described in Embodiment 1;

[0083] The ECG detector 401 and the finger pulse oxygen saturation detector 402 are both connected to the monitor 104, so that the monitor 104 displays the patient's ECG, finger pulse oxygen saturation waveform and real-time respiratory monitoring waveform.

[0084] Specifically, the ECG detector 401 contacts the patient's chest; the finger pulse oxygen saturation detector 402 contacts the patient's fingertips. The monitor 104 can display the patient's real-time multi-dimensional body functions. Figure 3 As shown in the figure, the first row is the electrocardiogram, the second row is the pulse oxygen saturation waveform, and the third row is the real-time respiratory monitoring waveform. This improves the safety and nursing effect of patients.
