Detailed implementation manners

[0018] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0019] Currently, the application number CN202323012528.4 discloses a tracheal monitoring information collection intubation device, which can detect sputum in intubated patients. However, its detection range of sputum is concentrated in the main trachea and the left and right main bronchi, and it is impossible to comprehensively detect sputum in patients, resulting in low applicability.

[0020] However, the present application can collect direct acoustic signals in the patient's lungs through a fiber optic pressure sensor or other types of acoustic sensors, and use this as a calibration wave to filter the external sound signals of the patient received by the acoustic sensor, and perform positioning calculations through the time and distance information between the signals, so as to accurately locate the position of the sputum and perform sputum drainage operations according to the position of the sputum.

[0021] The sputum processing device, method, storage medium and program product of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0022] Specifically, Figure 1 It is a block diagram of a sputum processing device provided by an embodiment of the present application.

[0023] As Figure 1 shown, the sputum processing device 10 includes: a sputum positioning device 100, a sputum drainage device 200, and a control component 300.

[0024] Among them, as Figure 2 and Figure 3 shown, the sputum positioning device 100 includes a target sensor component 101 and a projection device 102. The target sensor component 101 is used to collect acoustic data inside and outside the patient using different target sensors according to the actual situation of the patient; as Figure 2 and Figure 4As shown in the figure, the sputum drainage device 200 includes a sputum drainage tube 201 and a transducer 202. The sputum drainage tube 201 is used to select a corresponding insertion path according to the position of sputum in the patient's lungs, so as to reach the target sputum position of the patient and clear the sputum; the transducer 202 is arranged at the head of the sputum drainage tube and is used to emit sound waves of a target frequency; the control component 300 is used to receive the sound wave data collected by the target sensor component 101 in the sputum positioning device 100, calculate the target sputum position in the patient's lungs, control the projection device 102 to project to the corresponding body surface position of the patient according to the target sputum position, and control the transducer 202 of the sputum drainage device 200 to emit sound waves of a target frequency according to the target sputum position, so as to assist in positioning the sputum drainage tube 201 to reach the target sputum position.

[0025] It can be understood that in the embodiment of the present application, the target sensor component 101 in the sputum positioning device 100 can collect the sound wave data inside and outside the patient's body, so as to analyze the target sputum position in the patient's lungs, improve the accuracy of the sputum position, improve the work efficiency, and control the projection device 102 to project to the corresponding body surface position of the patient according to the target sputum position, so as to facilitate guiding the sputum drainage device 200 to enter the correct position to perform the sputum drainage process according to the target sputum position in the patient's lungs and the projection position, thereby improving the precise positioning of the sputum position during the sputum drainage process and reducing the probability of respiratory system damage to unconscious patients.

[0026] It should be noted that due to the popularization of laser technology and the significant reduction in cost, the current micro-projection device has a low cost. The projection device is selected as the position indicator for sputum, and the position data can be directly projected on the patient's body surface, which is convenient for auxiliary positioning during subsequent intubation. When intubating, adding an ultrasonic transducer to emit specific sound waves with high penetrability can also locate the position of the intubation head, thus greatly facilitating the discharge of sputum.

[0027] When deep sputum drainage is required and the sputum drainage tube needs to be inserted into the left and right main bronchi, a sputum drainage tube needs to be inserted, and a transducer, that is, a sound wave emitting device, is arranged in the sputum drainage tube. This device is connected to the audio output socket of the computer main board. As long as the selected frequency is output through the program, the sound waves of the desired frequency can be output through the transducer, and the waveform can be adjusted.

[0028] Specifically, as Figure 2 shown, the present application uses a set of movable medical platforms to install the main equipment, such as installing a computer main unit in the control box and using a touch screen. When critically ill patients or unconscious but stable patients develop pulmonary sputum accumulation due to infection, since they are all unable to expel sputum independently, medical staff are required to perform sputum drainage.

[0029] However, as mentioned before, it is difficult to detect sputum and safely expectorate it. When the patient is intubated, we can use the tracheal monitoring information acquisition intubation device to insert it into the target position of the patient and connect the sensor to this application. Therefore, the sensor in the tracheal monitoring information acquisition intubation device is connected to the audio acquisition card in the computer.

[0030] In the embodiment of this application, as Figure 3 shown, the target sensor assembly 101 includes a plurality of first target sensors 1011 and second target sensors 1012.

[0031] Among them, the first target sensor 1011 is used to penetrate into the left and right main bronchial parts to collect the sound wave data emitted by the patient's body; the second target sensors 1012 are arranged in a dot matrix to collect the sound wave data emitted by the patient's body externally at a distance.

[0032] Among them, the first target sensor can be a fiber optic pressure sensor, and the second target sensor can be a sound wave sensor, which can be selected according to actual needs and is not specifically limited.

[0033] It can be understood that in the embodiment of this application, the first target sensor 1011 can penetrate into the left and right main bronchial parts to collect the sound wave data emitted by the patient's body, and the second target sensors 1012 are arranged in a dot matrix to collect the sound wave data emitted by the patient's body externally at a distance. By combining the internal and external sound wave data, the accuracy of subsequent determination of the sputum position is improved, and the work efficiency is improved.

[0034] It should be noted that the target sensor assembly can include any type of sound wave sensor such as a sound wave sensor or a fiber optic pressure sensor. Among them, taking the FOP-M260 as an example, the fiber optic pressure sensor has the characteristics of small volume, high precision and reusability, and has become the standard evolution direction in micro pressure sensors. Due to its thin structure, it can penetrate into the left and right main bronchial parts through the patient's mouth to collect vibration sound information, and can also be directly used in the tracheal monitoring information acquisition intubation device to collect the sound wave data emitted by the patient in different situations according to the states of different patients.

[0035] Collect the direct sound wave signal of the patient's lungs through a fiber optic pressure sensor or other types of sound sensors, and use this as a calibration wave to filter the sound signal outside the patient received by the sound wave sensor, and perform positioning calculations through the time and distance information between the signals, so as to accurately locate the position of the sputum.

[0036] In the embodiment of this application, as Figure 3 shown, the sputum positioning device 100 further includes: a bell mouth structure 103, an adjustable boom 104 and a moving platform 105.

[0037] Among them, the flared structure 103 is arranged below the second target sensor 1012 to enhance the sound wave aggregation effect; the adjustable boom 104 is connected to the target sensor assembly 101 and the projection device 102 to adjust the position and angle of the target sensor assembly; the mobile platform 105 is fixedly connected to the adjustable boom and is used to flexibly move to the target position according to user needs.

[0038] It can be understood that in the embodiment of the present application, the flared structure 103 is used to enhance the sound wave aggregation effect and shield unnecessary background noise. The adjustable boom 104 adjusts the position and angle of the target sensor assembly to make the acquisition effect of the target sensor better. The mobile platform 105 flexibly moves to the target position according to user needs, improving the accuracy of the sputum position and the work efficiency.

[0039] It should be noted that the flared opening is mainly used to converge sound signals from a larger range to aggregate the sound waves, thereby increasing the sound energy and shielding unnecessary background noise, so that the sensor can obtain a stronger sound wave signal.

[0040] In the embodiment of the present application, as Figure 5 shown, the control component 300 includes: an acquisition card 301, a processor 302, and a display screen 303.

[0041] Among them, the acquisition card 301 is connected to the target sensor assembly and is used to receive the sound wave signals sent from the sensor array and convert the sound wave signals into digital signals; the processor 302 is connected to the acquisition card 301 and is used to calculate the target sputum position in the patient's lungs according to the digital signals; the display screen 303 is connected to the processor 302 and is used to display real-time data, operation interfaces, and alarm information.

[0042] It can be understood that in the embodiment of the present application, the acquisition card 301 receives the analog sound wave signals from the target sensor assembly and converts them into digital signals. The processor 302 uses common algorithms, such as fast Fourier transform, etc., to deeply analyze the digitized sound wave signals to determine the specific position of the sputum; the display screen 303 provides a clear and easy-to-understand operation interface, which can timely detect and remind medical staff when abnormal situations are detected, reducing the work burden of medical staff, improving work efficiency, and being able to timely discover potential problems to ensure the safety of patients.

[0043] It should be noted that the control component 300 is used for the calculation of the received data. Here, we use a mature development kit as the hardware basis, which has multiple signal access ports and can directly receive the sound wave signals from each transducer in the acoustic wave sensor; however, compared with a computer host, the data link that can be accessed is still less, while a computer host can directly insert multiple PCIe multi-channel high-speed acquisition cards to receive 32 or more sensors to achieve more accurate positioning.

[0044] Most acquisition cards use PCIe multi-channel high-speed acquisition cards, which are dedicated acquisition cards with multiple signal input interfaces connected to the computer's PCIe interface. The data used by the acquisition cards are mostly high-frequency digital acquisition modes. Dedicated acquisition cards have strong anti-interference capabilities and output digital signals with less noise information, which improves the quality of the acquired data.

[0045] According to the sputum processing device proposed in the embodiment of the present application, the target sensor component in the sputum positioning device collects sound wave data inside and outside the patient's body, thereby analyzing the target sputum position in the patient's lungs, improving the accuracy of the sputum position, and improving work efficiency. The projection device is controlled to project the target sputum position to the corresponding body surface position of the patient, so as to guide the sputum discharge device to the correct position to execute the sputum discharge process according to the target sputum position and the projection position of the patient's lungs, thereby improving the accurate positioning of the sputum position during the sputum discharge process and reducing the probability of respiratory system damage in unconscious patients.

[0046] Figure 6 A schematic diagram of a sputum processing method provided in an embodiment of the present application.

[0047] like Figure 6 As shown, the sputum processing method is applied to the sputum processing device of the above embodiment, wherein the method comprises the following steps: In step S101, the acoustic wave data collected by the target sensor assembly is acquired.

[0048] It is understandable that the embodiments of the present application can obtain the sound wave data collected by the target sensor component to facilitate the subsequent determination of whether the patient has sputum.

[0049] In an embodiment of the present application, before obtaining the sound wave data collected by the target sensor component, it includes: obtaining the current state of the patient; if the current state of the patient is an unconscious state, using the sensor of the tracheal monitoring information collection intubation device to collect the sound wave data inside the patient, and using the second target sensor arranged in a dot matrix manner to collect the sound wave data outside the patient through the air; if the current state of the patient is a state of autonomous breathing ability, using the first target sensor to penetrate into the left and right main bronchi to collect the sound wave data inside the patient, and using the second target sensor arranged in a dot matrix manner to collect the sound wave data outside the patient through the air.

[0050] It can be understood that the embodiments of the present application can select a suitable data collection mode according to the patient's current state, reduce the complexity of operations for medical staff, improve work efficiency, and can flexibly respond to various clinical situations. Whether it is an unconscious patient in an intensive care unit or a patient with autonomous breathing ability in a general ward, it can provide effective support and has high applicability.

[0051] In step S102, it is determined whether there is sputum in the patient according to the acoustic wave data. If there is sputum, the target sputum position in the patient's lungs is calculated, and the projection device is controlled to project to the corresponding body surface position of the patient according to the target sputum position.

[0052] It can be understood that in the embodiment of the present application, it can be determined whether there is sputum in the patient according to the acoustic wave data. If there is sputum, the target sputum position in the patient's lungs is calculated, and the projection device is controlled to project to the corresponding body surface position of the patient according to the target sputum position, thereby improving the accuracy of the sputum position and improving the work efficiency.

[0053] In the embodiment of the present application, determining whether there is sputum in the patient according to the acoustic wave data includes: performing Fourier calculation on the acoustic wave data to generate a frequency domain diagram; comparing the pre-stored spectrum data under normal breathing conditions with the frequency domain diagram to analyze abnormal acoustic waves; if the abnormal acoustic waves exceed a preset abnormal acoustic wave alarm threshold, it is determined that the patient has sputum, otherwise the patient does not have sputum.

[0054] Among them, the preset abnormal acoustic wave alarm threshold can be determined according to the results of multiple experiments, and no specific limitation is made.

[0055] It can be understood that in the embodiment of the present application, the acoustic wave data can be subjected to Fourier calculation to generate a frequency domain diagram; the pre-stored spectrum data under normal breathing conditions is compared with the frequency domain diagram to analyze abnormal acoustic waves; if the abnormal acoustic waves exceed the preset abnormal acoustic wave alarm threshold, it is determined that the patient has sputum, otherwise the patient does not have sputum. Through precise frequency domain analysis and comparison, the accuracy of sputum position determination is significantly improved, the possibility of misdiagnosis is reduced, the intuitive graphic display and the simplified operation process reduce the work burden of medical staff and improve the work efficiency.

[0056] In the embodiment of the present application, calculating the target sputum position in the patient's lungs includes: removing environmental data in the acoustic wave data to generate abnormal data; using trigonometric functions to calculate the target sputum position in the patient's lungs according to the time difference of the abnormal acoustic waves reaching different target sensors.

[0057] It can be understood that in the embodiment of the present application, the environmental data in the acoustic wave data can be removed to generate abnormal data; the target sputum position in the patient's lungs is calculated using trigonometric functions according to the time difference of the abnormal acoustic waves reaching different target sensors, improving the accuracy of sputum position positioning and improving the work efficiency.

[0058] It should be noted that when a sound wave source emits a signal, the signal will propagate in all directions at the same speed. Since the distances between each sensor and the sound wave source are different, the time for each sensor to receive the signal will also be different. The time difference can be used to infer the position of the sound wave source.

[0059] Specifically, the control system compares the timestamps from different sensors in pairs and calculates the time difference between each pair of sensors. The patient's body surface is regarded as a three-dimensional coordinate system in which the position of each sensor is known. The propagation path from the sound wave source to each sensor is constructed based on the propagation speed of sound waves in the air and the time difference between sensors. The intersection of multiple propagation paths, i.e., the three-dimensional coordinates of the origin point of the sound waves, is calculated, and the three-dimensional coordinates are converted into a two-dimensional projection of the patient's body surface.

[0060] In step S103, the sputum discharge device is guided to the correct position to perform the sputum discharge process according to the target sputum position and the projection position.

[0061] It can be understood that the embodiments of the present application can guide the sputum discharge device to the correct position to execute the sputum discharge process according to the target sputum position and the projection position, thereby improving the accurate positioning of the sputum position during the sputum discharge process and reducing the probability of respiratory system damage in unconscious patients.

[0062] According to the sputum processing method proposed in the embodiment of the present application, the target sensor component in the sputum locating device collects sound wave data inside and outside the patient's body, thereby analyzing the target sputum position in the patient's lungs, improving the accuracy of the sputum position, and improving work efficiency. The projection device is controlled to project the target sputum position to the corresponding body surface position of the patient, so as to guide the sputum discharge device to the correct position to execute the sputum discharge process according to the target sputum position and the projection position of the patient's lungs, thereby improving the accurate positioning of the sputum position during the sputum discharge process and reducing the probability of respiratory system damage in unconscious patients.

[0063] The following will be combined Figures 7 - 10 The sputum treatment method of the present application is described in detail as follows: Step 1, sputum processing device preparation stage The medical staff pushes the sputum processing device to the patient's bedside, ensures that the mobile platform 105 can be flexibly moved to the target position, and Figure 8 As shown, the control component and the projection device are connected to a power source; the control program on the control component is started to initialize the acquisition card 301, the processor 302 and the display screen 303.

[0064] Step 2: Acquisition of patient sound wave data The second sensor 1012 is arranged in a dot matrix manner and aimed at the top of the patient's lungs, and the sound wave data emitted from the patient's body is collected remotely. At the same time, according to the patient's current condition, the first pressure sensor 1011 or the tracheal monitoring information collection intubation device is selected to penetrate into the patient's left and right main bronchi to collect in vivo sound wave data. The projection device 102 is used for projection to set the projection position. After ensuring that the entire lung area is covered, the projection device can be turned off.

[0065] If the patient's current state is an autonomous consciousness state, insert the tracheal monitoring information collection intubation device, connect the sensor to the acquisition card to collect the body's sound wave data, and use the second target sensor 1012 to arrange in a dot matrix to collect the body's sound wave data remotely, and upload the sound wave data to the acquisition card 301.

[0066] If the patient is currently in a state of autonomous breathing ability, the first target sensor 1011 is inserted deep into the left and right main bronchi to collect in vivo sound wave data. Similarly, the second target sensor 1012 is arranged in a dot matrix to collect extracorporeal sound wave data in the air, and the sound wave data is uploaded to the acquisition card 301.

[0067] Step 3: Detection and anomaly monitoring When the patient breathes normally, the control component 300 automatically collects and stores complex sound wave data inside and outside the body to generate corresponding spectrum data and store them in the database, and sets corresponding sputum alarm thresholds based on these data.

[0068] The control component 300 continuously monitors the patient's sound wave data and analyzes in real time whether there are any abnormal conditions. When abnormal sound waves are detected that exceed a preset threshold, the system triggers an alarm mechanism.

[0069] It should be noted that during the waiting period, as long as the patient does not have sputum blockage and eventually recovers, it is only necessary to reverse the process in the above figure. Once the patient has sputum sounds that exceed the normal complex sound changes in the body, the sputum can be discharged through the sputum discharge process.

[0070] Specifically, when the control program sub-process is started for program monitoring, during the first Fourier calculation, only the data from the internal sensors is collected and applied. The sound wave data that can be received internally is the strongest. After calculation and comparison with the information in the database, it is compared with the sputum and abnormal sound wave alarm threshold. When the threshold is not exceeded, the delay time is returned and recalculated. When the threshold is exceeded, the program proceeds to the next level. At this time, the program turns on the sensor array, sounds an alarm and performs the next Fourier calculation.

[0071] Step 4: Calculate the target sputum location in the patient's lungs Recall the internal sound wave and environmental sound wave data under normal breathing conditions, collect data from internal sensors and sensor arrays for combined calculations, and after eliminating environmental data, generate abnormal sound wave time, frequency, and energy level parameters. Proceed to the next step, triangulation calculation, generate position function plane video, and turn on the projection device for projection.

[0072] Triangulation is performed through sound waves and a sensor array. That is, when a sound wave is generated and diffused, it is superimposed with complex sound waves in the environment. However, after high-speed sampling, these superimposed sound waves can be separated by each sensor to form digital signals. These digital signals indicating vibration, after inverse Fourier transformation, are divided into sound wave signals of various frequencies, and the energy magnitudes of various sound wave signals and the time sequence of arrival at the sensors can also be obtained. By calculating the phase difference of the time sequence, corresponding trigonometric functions can be obtained, and through calculation, the relative position of the sound wave origin point, that is, the target sputum position in the patient's lungs, can be obtained.

[0073] Step 5, Projection positioning and sputum drainage processing Medical staff first turn on the projection device 102 from the host by the alarm signal. At this time, the projection device 102 projects the position where the abnormal sound is found. If it is a gurgling sound, the suction catheter needs to be inserted into the main trachea of the patient. At this time, a catheter with the same cross-section as the pipeline in the tracheal monitoring information collection and intubation device can be used. First, set the transducer at the head of the catheter and turn on the auxiliary intubation program in the control program. (The length of the ventilator catheter only reaches the main trachea, so no assistance is required). At this time, the program will output an electrical signal of a specific frequency to the transducer 202 and convert it into a sound wave by the transducer, and the sensor array will preferentially extract this sound wave and perform triangulation calculation. The calculated position information is output to the projection device 102 in the form of a plane view step and projected on the body surface of the patient.

[0074] When the sputum drainage tube 201 is about to enter the left and right main bronchi during limited movement, this method can detect whether the tube deviates to the left or right and smoothly enter the two main bronchi. Entering once is less damaging to the patient's trachea than entering multiple times. By using a better algorithm, the detailed positional relationship between the tube and the trachea can be directly projected, thus completely avoiding damage. When the sputum drainage process is completed, medical staff can repeat the above process until the patient recovers.

[0075] In summary, in this application, direct sound wave signals in the patient's lungs are collected through fiber optic pressure sensors or other types of sound sensors, and used as calibration waves to filter the external sound signals received by the sound wave sensors. Positioning calculations are performed through the time and distance information between the signals. For the resolution of multiple sputum sites, calculations can also be performed through the multi-angle positioning method, and the position points are projected onto the human body through the projection device, thereby improving the accurate positioning of the sputum position during the sputum drainage process, accurately positioning the sputum position, so the positioning accuracy is high, avoiding the radiation damage caused by frequent photographing. When deep sputum drainage is required, the sputum drainage tube needs to be inserted deep into the left and right main bronchi to avoid strong stimulation or damage to the epidermis of other tracheas due to inaccurate positioning during bronchial suction, reducing the probability of respiratory system damage to unconscious patients.
