Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a control method, control device, and medical device for information broadcasting in medical devices. Background Technology

[0002] Medical devices typically have information broadcasting capabilities. For example, when a medical device detects an unexpected change in a patient's vital signs or when the device itself malfunctions or becomes abnormal, it can broadcast corresponding alarm information to prompt medical personnel to take appropriate action.

[0003] The volume of information broadcasts is a crucial parameter for medical equipment, impacting medical safety and the experience of both patients and healthcare staff. For example, a volume that is too low may prevent healthcare staff from hearing the broadcasts promptly, hindering the timely detection and handling of patient emergencies and increasing patient safety risks. Conversely, a volume that is too high may disturb patients' rest and can easily lead to alarm fatigue among healthcare staff, potentially causing medical accidents.

[0004] Currently, the volume of information broadcast by medical devices is usually adjusted manually. Summary of the Invention

[0005] The inventors discovered that traditional manual volume adjustment methods cannot automatically adjust volume based on factors such as ambient noise. When ambient noise changes, the previously manually adjusted volume may become inappropriate, thus failing to guarantee medical safety and the experience of patients and healthcare workers.

[0006] To address at least one of the above problems, embodiments of this application provide a control method, control device, and medical device for information broadcasting in a medical device.

[0007] According to one aspect of the embodiments of this application, a control method for information broadcasting of a medical device is provided, the method comprising: acquiring an ambient sound signal, identifying an ambient sound signal component in the ambient sound signal; adjusting the intensity of the ambient sound signal component according to a reference signal component in an audio database, thereby adjusting the intensity of the ambient sound signal; and automatically determining the broadcast volume according to the adjusted intensity of the ambient sound signal.

[0008] According to another aspect of the embodiments of this application, a control device for information broadcasting of a medical device is provided, the device comprising: a processor configured to execute the control method as described above.

[0009] According to another aspect of the embodiments of this application, a medical device is provided, the medical device comprising: an audio device for broadcasting information; and a control device as described above.

[0010] One of the beneficial effects of this application's embodiments is that it can automatically adjust the broadcast volume according to ambient sound. When the ambient sound changes, it can ensure that the broadcast volume is an appropriate volume corresponding to the ambient sound, thereby ensuring medical safety and the experience of patients and medical staff. Furthermore, the intensity of the ambient sound signal used to determine the broadcast volume is adjusted based on reference signal components in the audio database, avoiding the influence of incoherent ambient sound on the automatic adjustment of the broadcast volume. This allows for flexible and appropriate determination of the broadcast volume according to the actual scenario, better meeting user needs.

[0032] Features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments.

[0033] The following description is based on specific examples.

[0034] This application provides a method for controlling the information broadcasting of medical devices. Figure 1 This is a schematic diagram of a control method for information broadcasting of a medical device according to an embodiment of this application, as shown below. Figure 1 As shown, the method includes:

[0035] Step 101: Acquire ambient sound signals and identify the ambient sound signal components within the ambient sound signals;

[0036] Step 102: Adjust the intensity of the ambient sound signal component based on the reference signal component in the audio database, thereby adjusting the intensity of the ambient sound signal; and

[0037] Step 103: Automatically determine the broadcast volume based on the intensity of the adjusted ambient sound signal.

[0038] According to the above embodiments, an ambient sound signal is acquired, its components are identified, and the intensity of these components is adjusted based on reference signal components in an audio database. This adjustment of the ambient sound signal intensity, combined with the adjusted intensity, automatically determines the broadcast volume. Therefore, the broadcast volume can be automatically adjusted according to ambient sound, ensuring that the broadcast volume remains appropriate even when ambient sound changes. This guarantees medical safety and a better experience for patients and medical staff. Furthermore, since the intensity of the ambient sound signal used to determine the broadcast volume is adjusted based on reference signal components in the audio database, the influence of irrelevant ambient sound on the automatic adjustment of the broadcast volume is avoided. This allows for flexible and appropriate determination of the broadcast volume according to the actual scenario, better meeting user needs.

[0039] In some embodiments, a medical device can be a variety of medical-related devices. For example, a medical device may include devices for diagnosis, devices for treatment, and assistive devices.

[0040] As an example, a medical device can be a monitoring device. Monitoring devices are used to monitor vital signs and related parameters of a living being. These vital signs and related parameters may include: heart rate, blood oxygen saturation, non-invasive blood pressure (systolic, mean, and diastolic values), respiratory rate, central venous pressure, invasive arterial pressure (systolic, mean, and diastolic values), body temperature, urine output, brain function, respiratory mechanics, muscle relaxation, blood biochemistry, cardiac output, inhaled carbon dioxide partial pressure (FiCO2), end-tidal carbon dioxide partial pressure (EtCO2), inhaled oxygen concentration (FiO2), end-tidal oxygen concentration (EtO2), and the inhaled concentrations (Fi) and end-tidal concentrations (Et) of other balanced gases or anesthetic gases, entropy (state entropy (SE) and response entropy (RE)), surgical volume plethysmography index (SPI), bispectral index (BIS), electromyography series stimulation (TOF) ratio, peak inspiratory pressure (Ppeak), plateau pressure (Pplat), positive expiratory pressure (PEEP), expiratory minute ventilation (MVexp), expiratory tidal volume (TVexp), type of anesthetic gas, concentration of anesthetic gas, and flow rate of anesthetic gas. This application is not limited to this; vital signs-related parameters may also be other parameters.

[0041] In some embodiments, the ambient sound signal acquired by the medical device can be the ambient sound signal of the space where the medical device is located. Therefore, the broadcast volume of the medical device is matched to the ambient sound of its surrounding space. This application is not limited to this; the ambient sound signal acquired by the medical device can also be the ambient sound signal of the space where the medical personnel corresponding to the medical device are located. The medical personnel corresponding to the medical device can be those responsible for operating, managing, or maintaining the medical device. By acquiring the ambient sound signal of the space where the corresponding medical personnel are located, regardless of whether the medical personnel are in the same space as the medical device, the broadcast volume of the medical device can be matched to the ambient sound of the space where the medical personnel are located, thereby ensuring that the medical personnel hear the broadcast information in a timely manner.

[0042] In some embodiments, in step 101, the medical device can acquire ambient sound signals in various ways. For example, the medical device itself has a sound acquisition unit, through which it acquires ambient sound signals. The sound acquisition unit can be a microphone, etc. This application is not limited to this; the medical device can also acquire ambient sound signals from other devices connected to it.

[0043] In some embodiments, in step 101, the ambient sound signal components in the ambient sound signal can be distinguished in various ways. For example, the signal components can be distinguished according to the frequencies included in the ambient sound signal; that is, the signal components can be frequency components. For example, the frequency components included in the ambient sound signal can be obtained through Fourier transform, wavelet transform, etc. This application is not limited to this; the signal components can also be distinguished according to the different timbres of the sound in the ambient sound signal. Since the shape of the time-domain waveform of the sound signal is related to the timbre of the sound, the signal component can also be a component with a specific time-domain waveform, etc.

[0044] In some embodiments, in step 102, the intensity of the ambient sound signal component can be adjusted in various ways based on reference signal components in the audio database.

[0045] Figure 2 This is a schematic diagram illustrating an implementation of step 102 in an embodiment of this application. Figure 2 As shown, step 102 may include:

[0046] Step 201: Compare the reference signal component with the ambient sound signal component;

[0047] Step 202: Reduce or increase the intensity of the signal component in the ambient sound signal component that corresponds to the reference signal component.

[0048] By reducing or increasing the intensity of the signal component corresponding to the reference signal component in the ambient sound signal component, the influence of these ambient sound signal components on the broadcast volume can be weakened or emphasized when determining the broadcast volume. This allows the broadcast volume to be determined to an appropriate value based on the actual scenario, avoiding excessively high or low volumes. In other words, the embodiments of this application do not simply consider the presence and volume of background noise in the environment to adjust the volume of the medical device. This application analyzes the types of background noise and formulates corresponding volume adjustment strategies for different types of background noise. This ensures that the adjusted volume is audible to the user while avoiding unduly increasing the volume and causing adverse interference to the sound signals of other devices. A detailed description with examples follows.

[0049] In some embodiments, in step 201, the ambient sound signal component corresponding to the reference signal component is determined by comparing the reference signal component and the ambient sound signal component. The ambient sound signal component corresponding to the reference signal component can be an ambient sound signal component with the same frequency as the reference signal component. For example, if the frequency range of the reference signal component is [F1, F2], the ambient sound signal component with the frequency range [F1, F2] is taken as the ambient sound signal component corresponding to the reference signal component. This application is not limited to this; the ambient sound signal component corresponding to the reference signal component can also be an ambient sound signal component with the same shape as the time-domain waveform of the reference signal component, etc.

[0050] In some embodiments, the audio database may include various reference signal components. For example, the audio database may include at least one of the following: a first reference signal component from another medical device; a second reference signal component specified by the user; and a third reference signal component dynamically adjusted based on user feedback on the playback volume.

[0051] Therefore, when adjusting the intensity of the ambient sound signal, signal components from other medical devices, user-specified signal components, and components dynamically adjusted based on user feedback on the broadcast volume are taken into account. As a result, the intensity of the ambient sound signal can be adjusted to an appropriate value according to the actual scenario.

[0052] In some embodiments, when the ambient sound signal signal includes an ambient sound signal component corresponding to the first reference signal component, the intensity of that ambient sound signal component can be reduced for the first reference signal component from other medical devices. Therefore, in the presence of multiple medical devices simultaneously broadcasting information, mutual interference between the multiple medical devices can be prevented, and a continuous increase in broadcast volume can be avoided.

[0053] In some embodiments, the user-specified second reference signal component may be various signal components that the user expects to attenuate or emphasize in the ambient sound signal.

[0054] For example, the second reference signal component can be a sudden sound, such as the sound of a medical device colliding or falling, or the sound of a door closing or opening. When the ambient sound signal includes an ambient sound signal component corresponding to the second reference signal component, the intensity of that ambient sound signal component can be reduced. This prevents the broadcast volume from suddenly increasing. This application is not limited to this; the second reference signal component can also be other signal components.

[0055] For example, the second reference signal component can be the sound of a person speaking, the sound of a walkie-talkie, etc. For these second reference signal components, when the ambient sound signal includes an ambient sound signal component corresponding to the second reference signal component, the intensity of that ambient sound signal component can be increased. Because medical staff may focus their attention on the content of someone speaking, or because walkie-talkies are usually carried by medical staff, the volume they hear when the walkie-talkie is emitting sound may be louder than the volume detected in the ambient sound signal. In these cases, by increasing the intensity of the corresponding ambient sound signal component in the ambient sound signal, the influence of these ambient sound signal components on the broadcast volume can be emphasized, thereby enabling the broadcast volume to be determined to a value that allows medical staff to notice or hear the broadcast information promptly. This application is not limited to this; the second reference signal component can also be other signal components.

[0056] In some embodiments, the third reference signal component can be a signal component that is dynamically adjusted based on user feedback regarding the playback volume. This allows the audio database to be dynamically adjusted according to user habits, thereby ensuring that a given playback volume matches the user's preferences. The method for dynamically adjusting the audio database will be explained in detail later.

[0057] In some embodiments, in step 202, the intensity of the ambient sound signal component corresponding to the reference signal component in the ambient sound signal component can be reduced or increased in various ways.

[0058] For example, by adjusting the intensity of a corresponding ambient sound signal component by a certain margin, the adjusted intensity = the intensity before adjustment ± the adjustment margin. This adjustment margin can be related to the intensity of the ambient sound signal component before adjustment (i.e., the initial intensity). For example, the adjustment margin = initial intensity * adjustment ratio.

[0059] In some embodiments, reducing the intensity of an ambient sound signal component may include reducing the intensity of the ambient sound signal component to 0, that is, filtering out or deleting the ambient sound signal component from the ambient sound signal. In this case, the adjustment ratio is 100%.

[0060] In some examples, the adjustment ratios for different reference signal components in the audio database can be the same.

[0061] For example, the adjustment ratio corresponding to different reference signal components can be 100%. Taking intensity reduction as an example, the ambient sound signal component corresponding to the reference signal component is deleted from the ambient sound signal. This application is not limited to this, and the adjustment ratio can also be other values.

[0062] In other examples, the adjustment ratios for different reference signal components in the audio database can be different.

[0063] For example, reference signal components of the same type have the same adjustment ratio, while reference signal components of different types have different adjustment ratios.

[0064] Taking an audio database containing three types of reference signal components—a first reference signal component, a second reference signal component, and a third reference signal component—as an example, the adjustment ratios for the first and second reference signal components can be 100%. For example, to reduce intensity, the ambient sound signal components corresponding to the first and second reference signal components are deleted from the ambient sound signal signal. The adjustment ratio for the third reference signal component is 50%. For example, to reduce intensity, the intensity of the ambient sound signal component corresponding to the third reference signal component in the ambient sound signal signal is reduced to half of its original value. This application is not limited to this; the adjustment ratios can also be other values.

[0065] For example, reference signal components in an audio database can have weights, and the magnitude of the decrease or increase in intensity of the corresponding ambient sound signal component is determined based on the weight of the reference signal component. For instance, the weight of the reference signal component is proportional to the adjustment magnitude of the intensity of the corresponding ambient sound signal component. The weights of the reference signal components will be explained in more detail later.

[0066] In some embodiments, in step 103, the broadcast volume can be determined in various ways based on the intensity of the adjusted ambient sound signal. For example, the broadcast volume is proportional to the intensity of the adjusted ambient sound signal.

[0067] For example, the broadcast volume can be linearly adjusted based on the intensity of the adjusted ambient sound signal, thus enabling simple and efficient adjustment of the broadcast volume.

[0068] Figure 3 This is a schematic diagram illustrating the relationship between the intensity of the adjusted ambient sound signal and the broadcast volume, according to an embodiment of this application. Figure 3 As shown, the intensity range of the adjusted ambient sound signal [m0, m1] corresponds to the broadcast volume range [n0, n1]; the intensity range of the adjusted ambient sound signal [m1, m2] corresponds to the broadcast volume range [n1, n2]; and the intensity range of the adjusted ambient sound signal [m2, m3] corresponds to the broadcast volume range [n2, n3].

[0069] The rate of change of the broadcast volume with intensity can vary across different ranges of ambient sound signal intensity. For example, the rate of change of the broadcast volume with intensity is relatively low in the low-intensity range [m0, m1] and the high-intensity range [m2, m3]; while it is relatively high in the moderate-intensity range [m1, m2]. Therefore, when the ambient sound signal volume is low, the broadcast volume can be prevented from increasing too rapidly and affecting the patient; when the ambient sound signal volume is moderate, the broadcast volume can be effectively increased in accordance with the ambient sound volume; and when the broadcast volume has already been increased to a large value, it can prevent the broadcast volume from continuing to increase significantly.

[0070] This application is not limited to this, and the broadcast volume can also be determined in other ways. For example, the broadcast volume changes at the same rate with intensity across all ranges of the ambient sound signal intensity; or, the broadcast volume is adjusted non-linearly according to the intensity of the adjusted ambient sound signal; and so on.

[0071] As mentioned earlier, the audio database may include a signal component (a third signal component) that is dynamically adjusted based on user feedback regarding the broadcast volume. When the user provides feedback on the broadcast volume, for example, by increasing or decreasing the volume, it indicates that the current volume may not be suitable for the user's habits. In this case, the audio database can be adjusted so that the broadcast volume is adjusted to an appropriate value for the next information broadcast. The following is an illustrative example of how to dynamically adjust the reference signal component in the audio database.

[0072] like Figure 1 As shown, in an optional embodiment, the control method may further include:

[0073] Step 104: Adjust the audio database according to the ambient sound signal components.

[0074] For example, the medical device can store the ambient sound signal acquired in step 101, which is the ambient sound signal from a period of time prior to the information broadcast. The broadcast volume is determined based on this ambient sound signal using the methods described in steps 102 and 103. If user feedback on the broadcast volume is received during or after the information broadcast, such as increasing or decreasing the broadcast volume, the audio database can be adjusted based on the user's feedback on the broadcast volume and the ambient sound signal components in the stored ambient sound signal.

[0075] If the user provides feedback on the broadcast volume, it indicates that the intensity of the ambient sound signal used to determine the broadcast volume may be inappropriate. For example, some components of the ambient sound signal may not have been properly amplified or attenuated. In this case, adjusting the audio database based on the ambient sound signal corresponding to the broadcast can align the audio database with the user's usage habits. Consequently, during the next information broadcast, the intensity of the ambient sound signal can be adjusted to an appropriate value based on the reference signal components in the audio database, and thus, the broadcast volume can be adjusted to an appropriate value based on the adjusted ambient sound signal intensity.

[0076] In some embodiments, in step 104, the audio database may be adjusted in at least one of the following ways: adding at least one reference signal component to the audio database; deleting at least one reference signal component from the audio database; adjusting the weight of at least one reference signal component in the audio database, wherein the weight is used to adjust the intensity of the ambient sound signal component.

[0077] The above methods will be illustrated by examples below.

[0078] Figure 4 This is a schematic diagram of an embodiment of the addition of a reference signal component according to an example of this application. Figure 4 As shown, adding at least one reference signal component to the audio database includes:

[0079] Step 401: In response to user feedback on the broadcast volume, select the first ambient sound signal component in the ambient sound signal corresponding to this broadcast that is not included in the audio database as the first candidate signal component; and

[0080] Step 402: Determine the reference signal component to be added to the audio database based on the first candidate signal component.

[0081] In some embodiments, in step 401, the first ambient sound signal component can be determined in various ways. For example, the first ambient sound signal component can be selected based on the characteristics of ambient sound signal components in the ambient sound signal that are not included in the audio database. The characteristics of the ambient sound signal component may include frequency (related to the pitch of the sound), amplitude (related to the loudness of the sound), shape of the time-domain waveform (related to the timbre of the sound), etc. This application is not limited to this; all ambient sound signal components in the ambient sound signal that are not included in the audio database can also be selected as the first ambient sound signal component; or, the first ambient sound signal component can be selected through a trained learning model.

[0082] In some embodiments, in step 402, a reference signal component to be added to the audio database may be selected from the first candidate signal components in various ways. Figure 5 This is a schematic diagram illustrating an implementation of step 402 in an embodiment of this application. For example... Figure 5 As shown, step 402 includes:

[0083] Step 501: If the number of times the first ambient sound signal component is used as the first candidate signal component exceeds the first preset number, the first ambient sound signal component is added as a reference signal component to the audio database.

[0084] Therefore, while dynamically adjusting the audio database, it is possible to avoid frequent changes to the audio database, thereby ensuring the reliability and stability of the reference signal components included in the audio database and preventing the broadcast volume from fluctuating.

[0085] As mentioned earlier, when adjusting the intensity of the corresponding ambient sound signal component based on the reference signal component in the audio database, the intensity of the corresponding ambient sound signal component can be increased or decreased. The following sections will provide illustrative examples of how to dynamically adjust the audio database for each of these two methods.

[0086] Taking the reduction of the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0087] The user feedback that the volume should be lowered indicates that the broadcast volume was relatively high. Taking the broadcast volume as a direct correlation with the adjusted intensity of the ambient sound signal as an example, this means the adjusted intensity of the ambient sound signal was relatively high. In this case, the first ambient sound signal that meets the criteria is added to the audio database as a reference signal component. Therefore, in the next information broadcast, the intensity of more ambient sound signal components can be reduced, thus adjusting the ambient sound signal intensity to a slightly lower value than before, thereby lowering the broadcast volume.

[0088] Taking increasing the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0089] The user feedback that the volume should be increased indicates that the current broadcast volume is relatively low. Taking the broadcast volume as a direct correlation with the adjusted intensity of the ambient sound signal as an example, this means the adjusted intensity of the ambient sound signal is relatively low. In this case, the first ambient sound signal that meets the criteria is added to the audio database as a reference signal component. Therefore, in the next broadcast, the intensity of more ambient sound signal components can be increased, allowing the ambient sound signal intensity to be adjusted to a slightly higher value than before, thus increasing the broadcast volume.

[0090] Figure 6 This is a schematic diagram illustrating an implementation method for deleting the reference signal component according to an embodiment of this application. For example... Figure 6As shown, deleting at least one reference signal component from the audio database includes:

[0091] Step 601: In response to user feedback on the broadcast volume, the second ambient sound signal component included in the audio database in the ambient sound signal corresponding to this broadcast is selected as the second candidate signal component; and

[0092] Step 602: Determine the reference signal component to be deleted from the audio database based on the second candidate signal component.

[0093] In some embodiments, in step 601, the second ambient sound signal component can be selected in various ways. For example, the second ambient sound signal component can be selected based on the characteristics of the ambient sound signal components included in the audio database. This application is not limited to this; all ambient sound signal components included in the audio database can also be selected as the second ambient sound signal component; or, the second candidate signal component can be determined by a trained learning model.

[0094] In some embodiments, the second ambient sound signal component can be a signal component other than the first and second reference signal components in the audio database. This prevents the first and second reference signal components in the audio database from being accidentally deleted.

[0095] In some embodiments, in step 602, a reference signal component that has been removed from the audio database may be selected from the second candidate signal components in various ways. Figure 7 This is a schematic diagram illustrating an implementation of step 602 in an embodiment of this application. Figure 7 As shown, step 602 includes:

[0096] Step 701: If the second ambient sound signal component is used as the second candidate signal component more than a second preset number of times, the second ambient sound signal component is deleted from the audio database.

[0097] Therefore, while dynamically adjusting the audio database, it is possible to avoid frequent changes to the audio database, thereby ensuring the reliability and stability of the reference signal components included in the audio database and preventing the broadcast volume from fluctuating.

[0098] The following sections provide exemplary descriptions of two methods for dynamically adjusting the audio database: increasing the intensity of the ambient sound signal component corresponding to the reference signal component and decreasing the intensity of the ambient sound signal component corresponding to the reference signal component.

[0099] Taking the reduction of the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0100] The user feedback that the volume should be increased indicates that the current broadcast volume was too low. Taking the example that broadcast volume is directly proportional to the adjusted intensity of the ambient sound signal, this means the adjusted intensity of the ambient sound signal is relatively low. In this case, the second ambient sound signal that meets the criteria is deleted from the audio database. Therefore, in the next broadcast, the intensity of fewer ambient sound signal components can be reduced, allowing the ambient sound signal intensity to be adjusted to a slightly higher value than before, thus increasing the broadcast volume.

[0101] Taking increasing the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0102] The user feedback that the volume should be lowered indicates that the broadcast volume was too high. Taking the example that broadcast volume is directly proportional to the adjusted intensity of the ambient sound signal, this means the adjusted intensity of the ambient sound signal was relatively high. In this case, the second ambient sound signal that meets the criteria is deleted from the audio database. Therefore, in the next information broadcast, the intensity of fewer ambient sound signal components can be increased, thus adjusting the ambient sound signal intensity to a slightly lower value than before, thereby reducing the broadcast volume.

[0103] Figure 8 This is a schematic diagram illustrating an implementation method for adjusting the weights of reference signal components according to an embodiment of this application. For example... Figure 8 As shown, adjusting the weight of at least one reference signal component in the audio database includes:

[0104] Step 801: In response to user feedback on the broadcast volume, increase or decrease the weight of the third ambient sound signal component included in the audio database in the ambient sound signal corresponding to this broadcast.

[0105] In some embodiments, in step 801, the third ambient sound signal component can be selected in various ways. For example, the third ambient sound signal component whose weight needs to be adjusted can be selected based on the characteristics of the ambient sound signal components included in the audio database. This application is not limited to this; all ambient sound signal components included in the audio database can also be selected as the third ambient sound signal component; or, the third ambient sound signal component can be determined by a trained learning model.

[0106] In some embodiments, in step 801, the weight of the third ambient sound signal component can be adjusted in various ways. The following description exemplarily illustrates two methods: increasing the intensity of the ambient sound signal component corresponding to the reference signal component and decreasing the intensity of the ambient sound signal component corresponding to the reference signal component.

[0107] Taking the reduction of the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0108] The user feedback that the volume should be increased indicates that the current broadcast volume was too low. Taking the example that broadcast volume is directly proportional to the adjusted intensity of the ambient sound signal, this means the adjusted intensity of the ambient sound signal is relatively low. In this case, the weight of the qualifying third ambient sound signal is reduced. Therefore, in the next broadcast, the intensity of the corresponding ambient sound signal component can be reduced by a smaller amount, thus adjusting the ambient sound signal intensity to a slightly higher value than before, thereby increasing the broadcast volume.

[0109] The user feedback that the volume should be lowered indicates that the broadcast volume was relatively high. Taking the broadcast volume as a direct correlation with the adjusted intensity of the ambient sound signal as an example, this means the adjusted intensity of the ambient sound signal is relatively high. In this case, the weight of the qualifying third ambient sound signal is increased. Therefore, in the next broadcast, the intensity of the corresponding ambient sound signal component can be reduced significantly, thus adjusting the ambient sound signal intensity to a slightly lower value than before, thereby lowering the broadcast volume.

[0110] Taking increasing the intensity of the corresponding ambient sound signal component based on the reference signal component as an example:

[0111] User feedback that the volume should be increased indicates that the current broadcast volume was too low. Taking the example that broadcast volume is directly proportional to the adjusted intensity of the ambient sound signal, this means the adjusted intensity of the ambient sound signal is relatively low. In this case, the weight of the qualifying third ambient sound signal is increased. Therefore, in the next broadcast, the intensity of the corresponding ambient sound signal component can be increased significantly, thus adjusting the ambient sound signal intensity to a slightly higher value than before, thereby increasing the broadcast volume.

[0112] The user feedback that the volume should be lowered indicates that the broadcast volume was relatively high. Taking the example that the broadcast volume is directly proportional to the adjusted intensity of the ambient sound signal, this means the adjusted intensity of the ambient sound signal is relatively high. In this case, the weight of the third ambient sound signal that meets the criteria is reduced. Therefore, in the next broadcast, the intensity of the corresponding ambient sound signal component can be increased by a small amount, thus adjusting the ambient sound signal intensity to a slightly lower value than before, thereby reducing the broadcast volume.

[0113] In some embodiments, the weights of at least one reference signal component in the audio database may be adjusted each time a user provides feedback on the playback volume. This application is not limited to this; other methods may also be used to adjust the weights.

[0114] For example, recording the first number of times that at least one reference signal component in the audio database needs to have its weight increased over a period of time, and increasing the weight of that signal component based on the first recorded number of times. The magnitude of the weight increase can be proportional to the first number of times.

[0115] Record a second number of times that at least one reference signal component in the audio database needs to have its weight reduced within a certain period of time. The weight of the signal component is reduced according to the recorded second number of reductions. The magnitude of the weight reduction can be proportional to the second number of reductions.

[0116] If, within a certain period of time, the same reference signal component has both situations where its weight needs to be increased and situations where its weight needs to be decreased (i.e., the first and second counts are not equal to 0), then the weight of the reference signal can be adjusted based on the difference between the first and second counts.

[0117] Furthermore, when adjusting the weights of signal components, the magnitude of user volume adjustments (raising or lowering the broadcast volume) can be taken into account. For example, the weight adjustment could be proportional to the magnitude of the user volume adjustment.

[0118] The control method of this application will be described below using the example of filtering (deleting) the corresponding ambient sound signal component in the ambient sound signal based on the reference signal component. Figure 9 This is a schematic diagram of the flow of the control method according to an embodiment of this application.

[0119] like Figure 9 As shown, the medical device can record ambient sound signals for a period of time before an information broadcast, for example, the ambient sound signal 1-2 seconds before the broadcast. By processing this ambient sound signal, a digital signal is generated to identify the ambient sound signal components. First, second, and third reference signal components are acquired from an audio database. These reference signal components are compared with the ambient sound signal components; for example, the spectra of the reference signal components are compared and analyzed with the ambient sound signal components to filter out signal components with the same waveform as these reference signal components from the ambient sound signal.

[0120] To ensure the accuracy of the ambient sound signal, short, high-pitched sounds such as pulses can also be identified. When a high-pitched sound is included in the ambient sound signal, its duration can be detected. If the duration is less than a time threshold, the high-pitched sound can be filtered out of the ambient sound signal. Therefore, the medical device does not immediately adjust the broadcast volume when a high-pitched sound occurs, but rather adjusts it based on the high-pitched sound after it has persisted for a period of time, thus improving the stability of the ambient sound signal. This allows for the generation of an adjusted ambient sound signal, and the broadcast volume is then adjusted based on the adjusted ambient sound signal.

[0121] Figure 10This is a schematic diagram of an audio database according to an embodiment of this application. Figure 10 As shown, the audio database includes a first reference signal component. This first reference signal component includes, for example, the audio spectrum of the medical device, i.e., medical device spectrum 1, ..., medical device spectrum p, thereby enabling the filtering out of interference from other nearby medical devices.

[0122] like Figure 10 As shown, the audio database includes a second reference signal component. This second reference signal component may include, for example, a user-customized audio spectrum. For instance, a user can record a sound spectrum in "Record Filtered Sound" mode via a display on a medical device, i.e., recorded sound spectrum 1, ..., recorded sound spectrum q. The recorded sound spectrum is added to the audio database and filtered out from the ambient sound signal the next time the playback volume is determined.

[0123] like Figure 10 As shown, the audio database includes a third reference signal component. This third reference signal component may include, for example, an audio spectrum automatically optimized based on user habits. The automatic optimization operation can be implemented using a trained learning model.

[0124] For example, such as Figure 10 As shown, after the medical device broadcasts information, it determines whether it has received feedback from the user regarding the broadcast volume.

[0125] If the user selects "lower volume", a first ambient sound signal component is selected from the stored ambient sound signals and added to the pending library (i.e., the database of first candidate signal components). If the same first ambient sound signal component is added to the pending library multiple times, then the first ambient sound signal component is added to the audio database.

[0126] If the user selects "increase volume", a second ambient sound signal component is selected from the stored ambient sound signals and added to the analysis library (i.e., the database of second candidate signal components). If the same second ambient sound signal component is added to the analysis library multiple times, that second ambient sound signal component is deleted from the audio database.

[0127] In some embodiments, when the current medical device needs to broadcast information, the information can be broadcast through the current medical device itself. This application is not limited to this; information can also be broadcast through other medical devices, or through the current medical device itself and other medical devices in combination. This allows for more flexible selection of appropriate medical devices for information broadcasting.

[0128] like Figure 1 As shown, in an optional embodiment, the control method further includes:

[0129] Step 105: Obtain the location information of the medical personnel corresponding to the current medical equipment; and

[0130] Step 106: Based on the location information, select at least one medical device to broadcast.

[0131] Therefore, when current medical equipment needs to broadcast information, the appropriate medical equipment can be selected based on the location of medical staff to broadcast the information, thus ensuring that medical staff can hear the broadcast information in a timely manner.

[0132] For ease of description, the medical device that needs to broadcast information is referred to as the first medical device, and at least one medical device selected in step 106 is referred to as the second medical device.

[0133] In some embodiments, when the second medical device is different from the first medical device, the location information or identification information of the first medical device can also be broadcast through the second medical device. This facilitates medical personnel in determining the first medical device that needs to be operated or treated based on the information broadcast by the second medical device.

[0134] In some embodiments, the second medical device may also have the function of remotely controlling the first medical device. This allows healthcare personnel to operate or handle the first medical device from the second medical device.

[0135] In some embodiments, in step 105, the location information of the medical personnel corresponding to the current medical device can be obtained in various ways.

[0136] For example, RFID (Radio Frequency Identification) technology can be used to determine location information. This allows for the automatic identification of healthcare personnel and the reading and writing of relevant data via radio frequency signals, requiring no manual intervention and exhibiting strong environmental adaptability. For instance, healthcare personnel can be equipped with RFID tags (e.g., worn on name tags or ID cards); RFID readers can be installed on medical devices. When a healthcare worker is within a preset range of the medical device, the RFID reader automatically reads the information from the RFID tag and compares it with a pre-entered healthcare personnel database to identify whether the person is the corresponding healthcare worker. If the RFID tag information is included in the healthcare personnel database, it confirms that the corresponding healthcare worker is near the medical device.

[0137] This application is not limited to this; the location information of medical personnel can also be determined by other means. For example, non-contact bioradar detection technology, ultrasonic sensor ranging technology, etc.

[0138] In some embodiments, in step 105, the location information of the medical staff can be detected by the current medical device (the first medical device). Alternatively, the location information of the medical staff can also be detected by other medical devices. After other medical devices detect the location information of the medical staff corresponding to the first medical device, they can send the location information to the first medical device through a communication network.

[0139] In some embodiments, the location information of healthcare workers can be detected by more than one medical device. This improves the accuracy and reliability of the location information.

[0140] In some embodiments, in step 106, after obtaining the location information of the corresponding medical personnel, the medical device closest to the medical personnel can be selected to broadcast the information based on the location information. This further ensures that the medical personnel hear the broadcast information in a timely manner. Furthermore, since the medical device broadcasting the information is the closest to the medical personnel, the information can be broadcast at a lower volume, thus reducing disturbance to patients and lowering the energy consumption of the medical device.

[0141] This application is not limited to this; the medical device for broadcasting information may include the medical device closest to the medical staff and the medical device that needs to broadcast information (i.e., the first medical device). This makes it easier for medical staff to find the first medical device.

[0142] Figure 11 This is a schematic diagram illustrating the distribution of multiple medical devices according to an embodiment of this application. Figure 11 As shown, medical device C is located in room 1, while medical devices A and B are located in room 2. Medical staff are located in room 2, and medical devices A and B jointly identify their location. When medical device C needs to broadcast information, medical devices A and B send their identified locations to medical device C, thus enabling medical device C to also know the location of the medical staff.

[0143] Because medical devices A and B are closer to medical staff, medical device C can send the information that needs to be broadcast to medical devices A and B, and then medical devices A and B will broadcast the information from medical device C.

[0144] Figure 12 This is a schematic diagram illustrating an implementation of steps 105 and 106 of an embodiment of this application. For example... Figure 12 As shown, the medical device is turned on after its position is fixed; the layout of the target space is constructed, for example, by constructing the room layout through visual navigation technology; the distance between the medical device and the medical staff is identified; and the medical device to be broadcast is determined based on the identified distance.

[0145] In some embodiments, other factors may also be considered when determining the broadcast volume.

[0146] For example, the broadcast volume can be determined based on the distance between medical staff and medical equipment; for instance, the distance between medical staff and medical equipment is directly proportional to the broadcast volume.

[0147] For example, infrared sensors or distance sensors can be used to detect the distance between healthcare workers and medical equipment, and the volume level can be automatically adjusted based on the distance to ensure that the volume is appropriate when healthcare workers are nearby.

[0148] For example, the volume of the announcement can be adjusted based on the patient's condition. For instance, by combining the patient's vital signs data with their status assessment, such as when the patient is asleep, the announcement volume can be appropriately lowered to avoid disturbing their rest; conversely, if the patient's vital signs change drastically, the announcement volume can be increased to draw the attention of medical staff.

[0149] It is worth noting that the above figures are merely illustrative of embodiments of this application, and the application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed.

[0151] According to the above embodiments, an ambient sound signal is acquired, an ambient sound signal component within the signal is identified, and the intensity of the ambient sound signal component is adjusted based on a reference signal component in an audio database. This adjustment of the ambient sound signal intensity, combined with the adjusted intensity, automatically determines the broadcast volume. Therefore, the broadcast volume can be automatically adjusted according to the ambient sound, ensuring that the broadcast volume remains appropriate even when the ambient sound changes. This guarantees medical safety and a better experience for patients and medical staff. Furthermore, the intensity of the ambient sound signal used to determine the broadcast volume is adjusted based on the reference signal component in the audio database, avoiding the influence of irrelevant ambient sounds on the automatic adjustment of the broadcast volume. This allows for flexible and appropriate determination of the broadcast volume according to the actual scenario, better meeting user needs.

[0152] This application provides a control method for information broadcasting from a medical device. The control method includes: acquiring the location information of the medical personnel corresponding to the current medical device; and selecting at least one medical device to broadcast information based on the location information.
