Description

Technical Field

[0001] This application relates to the field of postoperative analgesia technology, and in particular to an intelligent postoperative analgesia method and device based on voice recognition control. Background Technology

[0002] Postoperative pain management is a crucial aspect of patient recovery, and patient-controlled analgesia (PCA) has become a widely used method of postoperative pain relief due to its rapid onset of action, personalized medication, and high satisfaction rate. Currently, analgesia pumps on the market are mainly divided into two types: mechanical and electronic.

[0003] Mechanical analgesic pumps have a simple structure and allow the dosage to be determined by observing the drug storage bag, but they lack precise control and dynamic adjustment capabilities. Electronic analgesic pumps, on the other hand, achieve drug infusion by setting parameters such as background dose, loading dose, and lockout time, and can monitor the infusion volume and remaining drug volume in real time.

[0004] However, traditional analgesic pumps often use fixed parameters set preoperatively, making it difficult to dynamically adjust the dosage according to individual differences in postoperative pain, resulting in unsatisfactory analgesic effects. Furthermore, existing analgesic pumps have limited monitoring capabilities, failing to promptly identify abnormal patient vital signs or medication use, and their safety needs improvement. Therefore, existing analgesic pumps still have significant shortcomings in terms of personalized analgesia, intelligent management, and medication safety, and cannot fully meet the needs of postoperative analgesia management.

At the same time, it improves the safety of postoperative analgesia and the personalized satisfaction of patients, and significantly optimizes the management of postoperative recovery.

[0051] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0052] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0053] Figure 1A flowchart illustrating an intelligent postoperative analgesia method based on voice recognition control provided in an embodiment of this application;

[0054] Figure 2 This is a schematic diagram of the structure of an intelligent postoperative analgesia device based on voice recognition control, provided in an embodiment of this application. Detailed Implementation

[0055] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0056] Traditional analgesic pumps often use fixed parameters set preoperatively, making it difficult to dynamically adjust the dosage based on individual differences in postoperative pain, resulting in unsatisfactory analgesic effects. Furthermore, existing analgesic pumps have limited monitoring capabilities, failing to promptly identify abnormal patient vital signs or medication use, and their safety needs improvement. Therefore, existing analgesic pumps still have significant shortcomings in terms of personalized analgesia, intelligent management, and medication safety, and cannot fully meet the needs of postoperative analgesia management.

[0057] To address this issue, this application provides an intelligent postoperative analgesia method based on voice recognition control. By introducing voice control technology, patients can directly activate and operate the analgesia pump via voice, achieving convenient and intelligent operation of the postoperative analgesia pump and avoiding the inconvenience of traditional button operation. This is particularly advantageous for patients with limited mobility. Through a dynamic dose adjustment mechanism based on the patient's postoperative pain feedback, the analgesic dose is precisely matched to the patient's individual pain sensitivity, avoiding the problems of insufficient or excessive analgesia caused by traditional fixed dose settings. At the same time, it improves the safety of postoperative analgesia and the personalized satisfaction of patients, significantly optimizing the management effect of postoperative recovery.

[0058] Figure 1 This is a flowchart illustrating an intelligent postoperative analgesia method based on voice recognition control, provided as an embodiment of this application. Figure 1 As shown, the method includes the following steps:

[0059] Step 101: Initialize the analgesia pump's analgesia infusion level to the intermediate level. The analgesia pump has multiple levels, arranged in ascending order of analgesia infusion dose.

[0060] In this embodiment, the intelligent voice-controlled analgesia pump has multiple fixed levels according to the manufacturer's default level settings, which can be divided into five levels: lowest (level 1), lower (level 2), middle (level 3), higher (level 4), and highest (level 5).

[0061] In some embodiments, the infusion parameters for the analgesic infusion grade are:

[0062] Lowest level (Level 1): Continuous dose set to 3 ml / h, PCA (single injection dose) set to 1.5 ml / time, lockout time set to 15 min.

[0063] Lower level (Level 2): ​​Continuous dose set to 3.5 ml / h, PCA (single injection dose) set to 1.75 ml / injection, and lockout time set to 15 min.

[0064] Intermediate level (Level 3): Continuous dose is set to 4 ml / h, PCA (single injection dose) is 2 ml / time, and lockout time is set to 15 min.

[0065] Higher level (Level 4): Continuous dose is set to 4.5 ml / h, PCA (single injection dose) is 2.25 ml / time, and lockout time is set to 15 min.

[0066] The highest level (level 5): continuous dose is set to 5 ml / h, PCA (single injection dose) is 2.5 ml / time, and lockout time is set to 15 min.

[0067] It should be noted that the analgesic infusion grades and their parameters described above are only used to illustrate the analgesic infusion grades proposed in this application and are intended to provide reference and do not constitute any limitation.

[0068] In this embodiment, intelligent voice-controlled analgesia is activated after power-on, and the default initial analgesia infusion level is intermediate.

[0069] In addition, in some embodiments of this application, the analgesic infusion level can be set manually, and the level can be divided into 10 more detailed levels according to the individual tolerance of the patient. This application will not describe or limit this further.

[0070] Step 102: In response to the patient experiencing discomfort, activate the analgesia pump via voice and control the analgesia pump to ask the patient whether there is insufficient or excessive analgesia.

[0071] In this embodiment of the application, after the patient experiences discomfort symptoms, the analgesia pump can be woken up by a specific voice command. For example, the analgesia pump can be woken up by a default wake-up word such as "analgesia pump" or "start analgesia", or by a custom wake-up word such as "pain worsening", "pain relief", or "adjust dosage" set by the patient. The analgesia pump can also be named, for example, by using "Xiao Zhi Xiao Zhi" to reactivate the smart analgesia pump.

[0072] It is understandable that the wake word needs to be set according to the actual scenario and the patient's customization. This application does not make specific restrictions on the method of activating the analgesia pump by voice.

[0073] In addition, in some embodiments of this application, to prevent other patients from accidentally triggering or waking up the analgesia pump, the following protection schemes can be adopted, including but not limited to voiceprint recognition technology, two-step wake-up verification, ambient sound filtering, and automatic exit after a short period of inactivity following wake-up. These schemes can be used individually or in combination; the specific choice should be optimized based on the patient's usage environment and needs.

[0074] For example, with voiceprint recognition technology, when a patient sets a wake word, the analgesia pump will require a sample to be recorded to ensure a match. The patient's voice characteristics are pre-stored in the device, and only voice commands that match a specific voiceprint will trigger the analgesia pump, thereby effectively preventing others from accidentally waking the patient and enhancing the personalized experience of the device.

[0075] For example, for two-step wake-up verification, a secondary verification step can be added after the wake word, such as requiring the patient to confirm the instruction, like "It's me, I need pain relief," or to input a touch confirmation, thereby reducing the risk of false wake-up, especially in public places or shared wards.

[0076] Of course, this application does not limit the specific implementation method of the protective measures. The above are only examples of implementation methods. Other methods can also be flexibly designed and applied according to specific needs. When the patient activates the analgesia pump, the analgesia pump will ask the patient whether there is insufficient or excessive analgesia. For example, the patient can reply with "I am here. What discomfort do you have? 1. Insufficient analgesia 2. Excessive analgesia, such as nausea, vomiting, drowsiness, etc."

[0077] Step 103: If the patient reports insufficient analgesia, control the analgesia pump to administer a single dose or increase the analgesia infusion level.

[0078] In this embodiment, if the patient reports insufficient analgesia, the analgesia pump is further controlled to inquire whether the patient requires a single dose. If the patient confirms, a fixed dose of analgesic drug is infused, and the current analgesia infusion level is maintained; if the patient refuses, no response is taken.

[0079] Additionally, if the patient reports insufficient analgesia for the third time within one hour, the analgesia pump will ask the patient if they need an increase in the analgesia infusion level. If the patient confirms and passes the password verification, the analgesia pump will increase the analgesia infusion level and administer the increased analgesia. If the patient refuses, the current analgesia infusion level will remain unchanged.

[0080] In this embodiment, the preset time window and number of feedback attempts can be set according to specific needs, and this application does not impose specific limitations on them. Under the default conditions, the time window is 1 hour and the number of feedback attempts is 3.

[0081] In certain scenarios, adjustments can be made individually based on the doctor's instructions. For example, the time window can be set to 30 minutes, 2 hours, or other durations; the number of feedback sessions can be set to 2 or 4, or dynamically adjusted according to the patient's tolerance and postoperative pain status. This application does not impose specific limitations on these aspects. This flexibility allows medical personnel to dynamically adjust triggering conditions based on the patient's postoperative recovery and analgesia needs, providing more precise and safer analgesia management.

[0082] In addition, if the current analgesia infusion level has been raised to the highest level but the patient still reports insufficient analgesia, the analgesia pump will automatically send an alarm to the main control system to remind the on-duty doctor to make rounds.

[0083] In this embodiment, upon receiving an alarm, the on-duty physician must immediately go to the ward to assess the patient's pain status and rule out possible serious postoperative complications, such as incision infection, internal bleeding, or other non-pain management issues. If the initial assessment suggests that the patient may require further intervention, the physician may contact the anesthesiology department for consultation. The anesthesiologist will readjust the analgesia plan and, if necessary, adopt other analgesia methods (such as epidural analgesia or nerve block).

[0084] Step 104: If the patient reports excessive analgesia, control the analgesia pump to stop the drug infusion or reduce the analgesia infusion level.

[0085] In this embodiment of the application, if the patient reports excessive analgesia, the analgesia pump is further controlled to ask the patient whether the analgesia drug infusion needs to be stopped; if the patient confirms, the analgesia drug infusion is stopped for 15 minutes, and the current analgesia infusion level remains unchanged.

[0086] Additionally, if the patient reports excessive analgesia for the third time within one hour, the analgesia pump will initiate further procedures, asking the patient if they wish to reduce the analgesia infusion level. If the patient confirms and passes password verification, the analgesia pump will reduce the current analgesia infusion level and immediately administer the reduced level of analgesia; if the patient refuses, the current analgesia infusion level will remain unchanged.

[0087] In this embodiment, the preset time window and number of feedback attempts can be set according to specific needs, and this application does not impose specific limitations on them. Under the default conditions, the time window is 1 hour and the number of feedback attempts is 3.

[0088] In certain scenarios, adjustments can be made individually based on the doctor's instructions. For example, the time window can be set to 30 minutes, 2 hours, or other durations; the number of feedback sessions can be set to 2 or 4, or dynamically adjusted according to the patient's tolerance and postoperative pain status. This application does not impose specific limitations on these aspects. This flexibility allows medical personnel to dynamically adjust triggering conditions based on the patient's postoperative recovery and analgesia needs, providing more precise and safer analgesia management.

[0089] In addition, if the current analgesia infusion level has been reduced to the lowest level but the patient still reports excessive analgesia, the analgesia pump will automatically send an alarm to the main control system to remind the on-duty doctor to make rounds.

[0090] In this embodiment, upon receiving an alarm, the on-duty physician must immediately go to the patient's ward to assess their sedation status and rule out potential risks of postoperative oversedation, such as drug metabolism disorders, dosage control errors, or other related issues. If the initial assessment indicates severe sedation or other complications, the physician may urgently contact an anesthesiologist for consultation. The anesthesiologist will adjust the analgesia regimen, and if necessary, discontinue the current analgesic infusion or administer an antidote such as naloxone (for opioid overdose).

[0091] In this embodiment of the application, if the patient does not activate the analgesia pump by voice or modify the analgesia infusion level by voice within one hour, the analgesia pump will actively remind the patient by voice whether there are symptoms of drowsiness or sleepiness.

[0092] If the patient reports drowsiness or sleepiness, the analgesia pump continues to remind the patient whether the analgesia infusion level needs to be reduced. If the patient confirms and passes the password verification, the analgesia pump is reduced to a lower analgesia level and the reduced level of analgesia is administered. If the patient refuses, the current analgesia infusion level is maintained. If the patient does not respond, the analgesia infusion is paused, and an alarm is sent to the main control system to remind the on-duty physician to make rounds and investigate possible postoperative drowsiness risks (such as drug side effects or excessive sedation).

[0093] In this embodiment, if the patient still does not respond after two consecutive active voice prompts, the analgesia pump will continue to prompt the patient to confirm whether to fix the analgesia infusion level. If the patient confirms and passes the password verification, the analgesia pump will maintain the current analgesia infusion level until the patient actively requests a change in the infusion procedure via voice. If the patient still does not respond at this point, the analgesia pump will remain paused and will again alarm the main control system to remind medical staff to intervene as necessary.

[0094] In this embodiment, the analgesia pump also connects to the hospital's intelligent pain management system and departmental monitoring system via a wireless network, and records the patient's vital signs in real time, including blood pressure, heart rate, and oxygen saturation. When the patient's vital signs are abnormal, the analgesia pump continuously and automatically alarms the main control system to remind the on-duty doctor to make rounds.

[0095] Abnormal indicators include, but are not limited to: oxygen saturation (SpO2 ≤ 92%); hypotension (≤ 90 / 60 mmHg); hypertension (≥ 180 / 110 mmHg); bradycardia (≤ 50 beats / min); and tachycardia (≥ 110 beats / min).

[0096] In addition, in this embodiment of the application, the analgesia pump also has a self-monitoring function, which can monitor its own working status. Once an abnormality occurs (such as the infusion rate exceeding the range, pipeline blockage, etc.), it can issue an alarm in time and stop the infusion to ensure the safety of the patient.

[0097] In addition, in this embodiment, the analgesia pump can also record key data during the postoperative analgesia process, such as infusion rate, dosage, and time. It can also analyze this data to provide reference for medical staff, help them to understand the patient's postoperative analgesia more accurately, and optimize the treatment plan.

[0098] To achieve the above embodiments, this application also proposes an intelligent postoperative analgesia device based on voice recognition control.

If the patient reports insufficient analgesia, the analgesia pump is controlled to administer a single dose or increase the analgesia infusion level, including: controlling the analgesia pump to ask the patient if they need a single dose; if the patient confirms, administering a fixed dose of analgesic medication and maintaining the current analgesia infusion level; if the patient reports insufficient analgesia for the third time within one hour, the analgesia pump is controlled to ask the patient if they need an increased analgesia infusion level; if the patient confirms and passes password verification, the analgesia pump is controlled to increase the analgesia infusion level and administer the increased analgesia level infusion; if the patient refuses, the current analgesia infusion level is maintained; if the current analgesia infusion level has been increased to the highest level but the patient still reports insufficient analgesia, the analgesia pump is controlled to automatically alarm the main control system to remind the on-duty doctor to make rounds. If the patient reports excessive analgesia, the analgesia pump is controlled to pause the drug infusion or reduce the analgesia infusion level, including: controlling the analgesia pump to ask the patient if they need to pause the analgesia drug infusion; if the patient confirms, the analgesia drug infusion is paused for 15 minutes, and the current analgesia infusion level is maintained; if the patient reports excessive analgesia for the third time within one hour, the analgesia pump is controlled to ask the patient if they need to reduce the analgesia infusion level; if the patient confirms and passes the password verification, the analgesia pump is controlled to reduce the analgesia infusion level and the reduced analgesia level infusion is performed; if the patient refuses, the current analgesia infusion level is maintained. The patient wakes up the analgesia pump through one or more of the following methods: specific voice command or voiceprint recognition technology, two-step wake-up verification, ambient sound filtering, and automatic exit after a short period of inactivity. If the patient does not activate the analgesia pump or modify the analgesia infusion level via voice within one hour, the system will actively remind the patient via voice whether they are experiencing drowsiness or lethargy. If the patient reports these symptoms, the system will remind the patient whether they need to lower the analgesia infusion level. If the patient confirms and passes the password verification, the system will lower the analgesia infusion level and administer the reduced level of analgesia. If the patient refuses, the current analgesia infusion level will remain unchanged. If the patient does not respond, the system will pause the analgesia infusion and alert the main control system to remind the on-duty doctor to make rounds. It also includes: recording the patient's vital signs in real time through the analgesia pump, including blood pressure, heart rate, and oxygen saturation; when the patient's vital signs are abnormal, controlling the analgesia pump to automatically alarm the main control system and remind the on-duty doctor to make rounds.

2. The method according to claim 1, characterized in that, Also includes: If the current analgesia infusion level has been reduced to the lowest level but the patient still reports excessive analgesia, the analgesia pump will automatically send an alarm to the main control system to remind the on-duty doctor to make rounds.

3. The method according to claim 2, characterized in that, Also includes: If the patient still does not respond after two consecutive active voice prompts, the analgesia pump will be controlled to remind the patient whether to fix the analgesia infusion level. If the patient confirms and passes the password verification, the analgesia pump is controlled to maintain the current analgesia infusion level until the patient actively requests a change in the infusion procedure via voice control.

4. A smart postoperative analgesia device based on voice recognition control, used to implement the method described in any one of claims 1-3, characterized in that, include: An initialization module is used to initialize the analgesic infusion level of the analgesic pump to the intermediate level. The analgesic pump is set with multiple levels, which are arranged in ascending order according to the analgesic infusion dose. The voice activation module is used to respond to a patient's discomfort symptoms by activating the analgesia pump via voice. The module controls the analgesia pump to inquire whether the patient experiences insufficient or excessive analgesia, including: controlling the analgesia pump to inquire whether the patient needs a single dose; if the patient confirms, administering a fixed dose of analgesic medication and maintaining the current analgesia infusion level; if the patient reports insufficient analgesia for the third time within one hour, controlling the analgesia pump to inquire whether the patient needs an increased analgesia infusion level; if the patient confirms and passes password verification, controlling the analgesia pump to increase the analgesia infusion level and administering the increased level of analgesia; if the patient refuses, maintaining the current analgesia infusion level; if the current analgesia infusion level has been increased to the highest level but the patient still reports insufficient analgesia, controlling the analgesia pump to automatically alarm the main control system, reminding the on-duty doctor to make rounds. The analgesia insufficiency handling module is used to control the analgesia pump to perform a single dose or increase the analgesia infusion level if the patient reports insufficient analgesia. The analgesia overdose handling module is used to control the analgesia pump to pause drug infusion or reduce the analgesia infusion level if the patient reports excessive analgesia. The patient wakes up the analgesia pump through one or more of the following methods: specific voice command or voiceprint recognition technology, two-step wake-up verification, ambient sound filtering, and automatic exit after a short period of inactivity. Specifically, if the patient does not activate the analgesia pump via voice or modify the analgesia infusion level via voice within one hour, the analgesia pump will proactively remind the patient via voice whether they experience drowsiness or lethargy. If the patient reports such symptoms, the analgesia pump will remind the patient whether they need to lower the analgesia infusion level. If the patient confirms and passes the password verification, the analgesia pump will lower the analgesia infusion level and administer the lowered analgesia level infusion. If the patient refuses, the current analgesia infusion level will remain unchanged. If the patient does not respond, the analgesia infusion will be paused, and an alarm will be sent to the main control system to remind the on-duty doctor to make rounds.

5. An electronic device, characterized in that, include: A processor, and a memory communicatively connected to the processor; The memory stores computer-executed instructions; The processor executes computer execution instructions stored in the memory to implement the method as described in any one of claims 1-3.
