Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the description of the embodiments of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In order to solve the problem that the protection effect of the WCD provided in the related art is limited under the condition of unstable emotion of a patient, an embodiment of the present application provides a WCD control method based on emotion recognition, which can be implemented under the condition that the WCD is offline or online, when the WCD is offline, an execution subject of the method can be the WCD itself, and when the WCD is online, the execution subject of the method can be the WCD itself and/or a background server.
Fig. 1 is a basic flowchart of a WCD control method based on emotion recognition according to the present embodiment, which includes the following steps:
Specifically, in the present embodiment, the physiological parameter of the patient is a physiological parameter related to the emotional state of the patient, that is, a physiological parameter that adaptively changes when the emotional state of the patient fluctuates, such as heart rate, chest impedance, and body temperature. It should be noted that, in this embodiment, the physiological monitoring component may be a single or multiple physiological parameter types of the patient may be a single or multiple physiological parameter types, which is not limited to this embodiment. It should be noted that in practical application, the WCD may submit a registration request to the background server, where the background server performs validity authentication on the WCD, and if the authentication passes, the WCD registers successfully to become a registered WCD, allowing interaction with the background server, so as to implement a WCD control method based on emotion recognition.
In an alternative implementation of this embodiment, the WCD is configured with a first electrocardiograph electrode, a second electrocardiograph electrode, and a body temperature sensor, the second electrocardiograph electrode being configured to acquire patient electrocardiographic signals. Correspondingly, the step of acquiring the physiological parameters of the patient continuously acquired by the physiological monitoring component configured by the WCD in the preset parameter acquisition period comprises the following steps: acquiring a heart rate, a chest impedance and a respiratory rate of a patient continuously acquired by a first electrocardio electrode configured by the WCD in a preset parameter acquisition period, and a body temperature of the patient continuously acquired by a body temperature sensor in the parameter acquisition period; wherein the patient physiological parameters include patient heart rate, patient thoracic impedance, respiratory rate, and patient body temperature.
It should be noted that when the emotion of a person fluctuates, sweat gland secretion changes, resulting in skin impedance changes, particularly chest impedance data changes significantly. In practical applications, the WCD is conventionally configured with an electrocardiograph electrode (i.e., the above-mentioned second electrocardiograph electrode) for collecting the electrocardiograph signal of the patient required by the defibrillation analysis, however, in order to ensure the signal quality of the electrocardiograph signal of the patient required by the defibrillation analysis, lubricating oil is generally applied on the contact surface between the second electrocardiograph electrode and the skin to reduce the thoracic impedance and improve the electrocardiograph signal quality, so that the problem of inaccuracy exists when the thoracic impedance is directly collected by adopting the second electrocardiograph electrode. It should be noted that, in practical applications, the respiration rate may be calculated based on the chest impedance of the patient.
Specifically, the first period of time in this embodiment is longer than the second period of time, and the end time of the first period of time and the end time of the second period of time may be the end time of the parameter acquisition period, for example, the first period of time may be the last 2 minutes of the parameter acquisition period, and the second period of time may be the last 5 seconds of the parameter acquisition period, as shown in fig. 2, which is a schematic diagram of period setting provided in this embodiment, in which T is 1 To T 4 The limited interval is a parameter acquisition period, T 4 Indicating the ending time of the parameter acquisition period and also the ending time of the first period and the second period, T 2 Indicating the starting time of the first period, T 3 Indicating the start of the second period, it can be seen that T 2 To T 4 The defined first period of time corresponds to a duration greater than T 3 To T 4 A defined second period of time. In practical application, the physiological monitoring component collects a physiological parameter of a patient at each sampling time, and then a plurality of physiological parameters of the patient are collected at the first time period and the second time period to form a physiological parameter set of the patient.
Specifically, when calculating the first characteristic physiological parameter and the second characteristic physiological parameter, the embodiment can be flexibly implemented in different manners, in one implementation manner, a weighted average value can be obtained based on a plurality of patient physiological parameters in the patient physiological parameter set, and the weighted average value can be used as the characteristic physiological parameter, in another implementation manner, intermediate values of a plurality of patient physiological parameters in the patient physiological parameter set can be obtained as the characteristic physiological parameter.
In an alternative implementation manner of this embodiment, first, deviation indexes of second characteristic physiological parameters of a plurality of different types of physiological parameters of a patient relative to the first characteristic physiological parameters are respectively counted, and then, the emotional state of the patient is determined by combining the corresponding deviation indexes of the plurality of different types of physiological parameters of the patient.
It should be noted that, the emotion types of the emotion fluctuations of the patients are different, and the measurement standards of the emotion fluctuations of different patients are also different, if the emotion states of the patients are evaluated by using the fixed physiological parameter reference values, the accuracy of the emotion state evaluation results is poor. Based on this, in this embodiment, the physiological parameter of the patient is actually acquired in a long period in the parameter acquisition period to obtain the first characteristic physiological parameter as the physiological parameter reference value, then a deviation index of the second characteristic physiological parameter in a short period relative to the first characteristic physiological parameter is calculated, for example, the amplitude of the second characteristic physiological parameter exceeding the first characteristic physiological parameter is calculated, and finally the deviation index can be compared with a preset deviation index threshold value, and the emotional state of the patient is determined according to the comparison result, wherein the emotional state of the patient includes a stable emotional state and an unstable emotional state.
More specifically, in order to ensure accuracy of determining the emotional state of the patient to the greatest extent, the embodiment calculates corresponding deviation indexes based on a plurality of different types of physiological parameters of the patient, and then determines the emotional state of the patient by combining the deviation indexes, for example, determines whether the number of the deviation indexes, which is greater than a preset deviation index threshold, is greater than a preset number threshold, and if yes, determines that the emotional state of the patient is an unstable emotional state.
Further, in practical applications, the corresponding emotion types of the unstable emotion states are different, and the unstable emotion types may include happiness, anger, sadness, fear, and the like.
Specifically, the emotion soothing voice of the embodiment is used for guiding a patient to calm emotion, the unstable emotion state is an initial emotion unstable state, that is, the absolute value of the deviation index threshold is smaller than the corresponding target deviation index of the extreme emotion unstable state which causes the malignant heart rhythm of VF/VT, so that the patient is interfered when the initial emotion of the patient is unstable, the patient is guided to calm emotion in time, the situation that the emotion is continuously deteriorated to cause the malignant heart rhythm to trigger the electric shock treatment of the WCD is avoided, and the damage to the body of the patient is reduced. It should be appreciated that the present embodiment may also control the WCD to output an emotion control prompt, such as playing a prompt sound, controlling motor vibration, etc., before controlling the WCD to output the first emotion soothing voice, to prompt the patient to attempt to self-calm emotion. In addition, the emotion soothing voice in this embodiment may be a voice preset by the background system or a voice pre-stored by the WCD, or may be a personalized voice generated in real time.
In an alternative implementation of this embodiment, the step of controlling the WCD to output the first emotion voice includes: determining a target associated user identifier with highest emotional intervention priority from a plurality of associated user identifiers; wherein, emotional intervention priority is positively correlated with patient confidence in the associated user; the WCD is controlled to output a first emotion soothing voice corresponding to the target associated user identification.
In practical application, if the WCD is required to be controlled to conduct voice guidance when the patient is in an unstable emotion state, default voice configured by the factory of the equipment can be adopted for reminding, but the voice is mechanized and is easy to be ignored by the patient with immature mind or mind loss, namely, the default voice guidance of the equipment is easy to be ignored subjectively by the patient, and effective guidance is difficult to be formed for the patient.
In this embodiment, the associated user may be a family, a friend, a doctor, an online customer service, etc. of the patient, and the associated user may request association from the background server through its own terminal device, that is, bind the associated user identifier with the unique identifier of the WCD. It should be appreciated that the patient's confidence level in the various associated users may be different, the patient may only give a higher confidence in some of the particular associated users and compare the utterances of those associated users to be audible, while the utterances of other associated utterances may not be focused or even intentionally violated. Based on the above, when the patient is detected to be in an unstable emotion state, the target associated user identifier with the highest prompt priority is selected from all the associated user identifiers, and then corresponding emotion soothing voice is output.
In an alternative implementation of this embodiment, the step of controlling the WCD to output the first emotion voice corresponding to the target associated user identification includes: sending a communication connection request to a target user terminal corresponding to the target associated user identifier; when a confirmation connection response fed back by the target user terminal is received, establishing communication connection between the target user terminal and the WCD; and controlling the WCD to output the first emotion soothing voice which is instantly transmitted by the target user terminal based on the communication connection.
Specifically, the embodiment can implement emotional intervention of the patient in an instant voice communication manner, that is, when the patient is in an unstable emotion state, a communication connection request carrying an emotion fluctuation event is sent to the target user terminal so as to establish communication connection between the target user terminal and the WCD, and the target associated user is allowed to send voice to the WCD through the terminal so as to guide the patient to calm the unstable emotion.
In an alternative implementation of this embodiment, after the step of controlling the WCD to output the first emotion voice corresponding to the target associated user identification, the method further includes: acquiring interval duration between the output time of the first emotion soothing voice and the target time for recovering the stable emotion state of the emotional state of the patient; determining a corresponding priority score adjustment value based on the interval duration; updating the priority score corresponding to the target associated user identifier based on the priority score adjustment value; and rearranging emotional intervention priorities of all the associated user identifications based on the updated priority scores.
Specifically, in this embodiment, considering that the actual effectiveness of the voice prompt of the associated user when guiding the patient to calm emotion is not exactly matched with the initial priority of the corresponding associated user identifier, the time spent by the patient to restore the stable emotion is counted from the output time of the emotion soothing voice, and the priority score adjustment value of the target associated user identifier is correspondingly determined according to the time, so as to adjust and update the priority score corresponding to the initial priority, for example, when the interval time is longer than the preset first time threshold and is smaller than the second time threshold, the priority score adjustment value is correspondingly determined to be-10, and when the interval time is smaller than the first time threshold, the priority score adjustment value is correspondingly determined to be +10, and after the priority score update of the target associated user identifier, the emotion intervention priorities of all the associated user identifiers are adaptively adjusted, so that the emotion intervention priority of the associated user is adaptively adjusted according to the actual voice guiding effect, and the voice guiding effectiveness of the associated user with the highest emotion intervention priority is ensured. It should be noted that, in this embodiment, the lowest priority score may theoretically be 0 score, and if the priority scores of all the associated user identifiers are lower than the preset score in the actual application, default emotion pacifying voice configured by the factory of the WCD may be adopted.
In an optional implementation manner of this embodiment, after the step of controlling the WCD to output the first emotion soothing voice that is immediately sent by the target user terminal based on the communication connection, the method further includes: when the actual time consumption of recovering the stable emotional state of the patient is lower than the preset expected time, extracting first language text information corresponding to the first emotion soothing voice; extracting keywords in the first language text information, and adding the keywords into keyword groups of emotion types corresponding to the unstable emotion states; and when the emotional state of the patient is detected to be the unstable emotional state again, controlling the WCD to output second emotion soothing voice based on the keyword group corresponding to the emotion type of the unstable emotional state.
Specifically, in practical application, if the emotion soothing voice of the target associated user successfully guides the patient to restore the stable emotion state within the expected duration, the fact that the emotion soothing voice is high in effectiveness is explained, language text information of the emotion soothing voice is extracted, keywords of the emotion soothing voice are further extracted, the keywords are added to keyword groups corresponding to emotion types when the patient is in an emotion unstable event, the keywords in the keyword groups have substantial reference significance for guiding the patient with the corresponding emotion types, when the patient is in the emotion unstable event again later, the target associated user is not required to conduct voice guiding on the patient in an instant communication mode, the corresponding emotion soothing voice can be intelligently generated based on the keyword groups corresponding to the emotion types of the patient at the moment, and then the WCD is controlled to output the intelligently generated emotion soothing voice, so that convenience of emotion intervention is improved.
It should be noted that, in the embodiment, when keyword grouping statistics are performed, the emotion type may be used as a primary catalog, a secondary catalog may be further set for the emotion type, for example, patient history, age, gender, etc., and then keywords may be added to the corresponding groupings of the secondary catalog in practical applications. In addition, in practical application, aiming at the same type of emotion unstable event of a patient, effective guidance can be realized by using different emotion soothing voices, so that corresponding keywords of the same emotion type are grouped, the same keywords appear in different emotion soothing voices, and then the same keywords can be accumulated in an adding frequency.
In an alternative implementation of this embodiment, the step of controlling the WCD to output the first emotion voice includes: creating an online emotional intervention worksheet corresponding to the unstable emotional state, and sending the online emotional intervention worksheet to a plurality of online customer service clients; when receiving a work order receiving response sent by the target online customer service client, sending an emotion intervention task execution instruction to the target online customer service client; and outputting the first emotion soothing voice sent by the target online customer service client to the WCD.
Specifically, in practical application, the background of the embodiment can be configured with online customer service, when a patient is in an unstable emotion state, the background creates a corresponding online emotion intervention work order, then pushes the work order to a plurality of online customer service clients at the same time, and then sends an emotion intervention task execution instruction to a response target online customer service client to allow the target online customer service client to online intervene in the emotion pacifying work of the patient, namely, the online customer service sends a first emotion pacifying voice through the target online customer service client, and then the background server outputs the first emotion pacifying voice to the WCD, so that the remote pacifying of the patient is realized.
Further, in an alternative implementation manner of this embodiment, before the step of creating the online emotional intervention worksheet corresponding to the unstable emotional state, the method further includes: controlling the WCD to output locally pre-stored default emotion soothing speech; detecting whether the emotional state of the patient is recovered to a stable emotional state within a preset expected duration from the output time of the default emotion soothing voice; if the stable emotional state is not restored, the step of creating an online emotional intervention worksheet corresponding to the unstable emotional state is performed.
Specifically, in this embodiment, the voice of the associated user may be recorded in advance, and then the recorded voice is stored in the WCD as a default emotion soothing voice, when it is confirmed that the patient is in an unstable emotion state, the WCD is first controlled to output the locally pre-stored default emotion soothing voice, if the default emotion soothing voice cannot assist the patient in effectively recovering the stable emotion state in the expected duration, the foregoing flow of on-line emotion intervention is further executed, so that human resources consumption caused by on-line customer service intervention directly in a basic emotion intervention scene is avoided.
Further, in an optional implementation manner of this embodiment, after the step of outputting the first emotion soothing voice sent by the target online customer service client to the WCD, the method further includes: acquiring interval duration between the output time of the first emotion soothing voice and the target time for recovering the stable emotion state of the emotional state of the patient; determining a corresponding service score of the target online customer service client according to the interval duration; when the patient emotional state is determined to be an unstable emotional state again based on the patient physiological parameters acquired by any registered WCD, a new online emotional intervention worksheet corresponding to the unstable emotional state is created, and the new online emotional intervention worksheet is sent to an online customer service client with a service score higher than a preset score threshold.
Specifically, in this embodiment, service scoring is performed on the target online customer service client based on the time when the patient is successfully calmed to a stable emotion state by emotion calm voice, if the time is shorter, the effectiveness of emotion calm voice is higher, so that a higher service score is given to the target online customer service client, and when an unstable emotion state occurs to the patient again in the following process, the background server can only dispatch a work order to the online customer service client with a higher service score, so that the online customer service corresponding to the online customer service client receiving the work order has a higher emotion calm capability. It should be noted that, in this embodiment, a plurality of WCDs may register to a background server to apply for emotion soothing service, and if a specific WCD user (i.e., a patient using the WCD) is previously successfully soothing by an online customer service corresponding to a target online customer service client when an unstable emotion state is generated, a work order may be preferentially dispatched to the target online customer service client having a high service score when the unstable emotion state is generated by the subsequent arbitrary registration WCD user.
