Description

Technical Field

[0001] The present invention relates to the technical field of medical care services, and more specifically to an intelligent nurse device and a smart nurse station system based on AI voice control. Background Art

[0002] Most hospitals in China are short of nurses, and the ratio of patients to nurses is seriously unbalanced. Nurses are often too busy to handle the situation, which in turn gives patients a poor experience and a feeling of being ignored, causing conflicts between doctors and patients. How to improve the efficiency of nurses, bring patients a better hospitalization experience, and improve patient satisfaction has become a major social issue. A Chinese patent (publication number CN108471480A) discloses a multi-receiving end intelligent nurse call system, including an intelligent nurse call connection mode and a multi-receiving end intelligent nurse call system. The intelligent nurse call connection mode is composed of a signal transmitting port, a PC console and a receiving end. The signal transmitting port sends a signal to the receiving end through the PC console, and the receiving end transmits the signal to the staff. The receiving end intelligent nurse call system controls the calling device; when a patient is sick, the patient presses the alarm button, and then transmits the signal to the data transmission module through the Internet and the PC terminal. The data transmission module receives and analyzes the data, and then feeds the signal back to the console. The on-duty personnel of the console understand the bed location through the signal receiving end and the signal display, and then dispatches the staff to conduct voice dialogue, remote observation and remote control equipment. The one-to-many service still makes the nurses busy and prone to errors, and various remote devices are expensive, and the hospitalization experience of patients who cannot receive face-to-face nurse service is also very poor. A Chinese patent (publication number CN209070574U) discloses an intelligent nurse badge, which includes a main control module and a WIFI module provided in the intelligent part of the badge, and is connected to the hospital management system through the WiFi module to realize real-time information transmission to the nurse. However, it does not have the function of switching the working state mode when the fixed point is automatically connected, so that the nurse is still very busy when returning to the nurse station and cannot handle the work of the nurse station. Moreover, it does not have the function of autonomous learning. Some difficult questions still need to be answered by the staff and input into the system, which not only requires more personnel, but also complicates the work process and reduces the work efficiency of nurses. The present invention aims to improve the patient's hospitalization experience, make the hospitalization environment more warm, make the work of nurses easier, and make the society more harmonious.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0004] In response to the problems in the related art, the present invention proposes an intelligent nurse device and a smart nurse station system based on AI voice control to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] The present invention adopts the following technical solution:

[0006] An intelligent nurse device based on AI voice control, comprising a voice audio robot with AI voice recognition capability and an infrared pyroelectric sensor, an intelligent nurse card installed on the nurse work card in a card-connected manner, a communication module with a Bluetooth module and an edge computing device with AI voice processing capability, a cloud platform computing server with AI voice processing and AI voice training capabilities, a computer room and a nurse station; wherein the voice audio robot is provided with a CPU, a voice recognition sensor, an infrared pyroelectric sensor, a voice playback module, a WiFi module and a second Bluetooth module; the intelligent nurse card is provided with a third Bluetooth module and a vibration module;

[0007] Among them, the edge computing device is arranged in a computer room and the terminal is connected to the cloud platform computing server through an optical fiber. A switch and a local area network transmission system are arranged in the computer room. The local area network transmission system includes a fixed network cable port arranged in the hospital through a network cable. The switch is connected to the edge computing device and the local area network transmission system respectively through a network cable. The communication module is connected to the fixed network cable port through a network cable. The voice audio robot is arranged on the nurse's table and connected to the fixed network cable port through a network cable. The smart nurse card is connected to the communication module or the voice audio robot. When connected, the voice audio robot forms two different working status modes.

[0008] As a preferred technical solution, the infrared pyroelectric sensor includes a transmitter and a receiver, and the signal receiving range of the transmitter and the receiver is 0.2-0.4m. The transmitter is used to emit infrared rays with heat, which can be received within the range of 0.2-0.4m during operation. Once it is irradiated to the human body, it will be reflected. The receiver receives the energy of the reflected ultraviolet rays. Due to the energy difference calculated, it begins to judge that someone comes to consult, and sets the receiving range of 0.2-0.4m. In order to ensure that the person being detected is indeed close to the nurse station for consultation, and to ensure that he is basically close to the nurse station, not only will the inadvertent passers-by not be detected at too far a distance, causing information misjudgment and affecting the work of the nurse, but also people who do come to consult at close range will not deliberately get close to the voice audio robot, and even for people who do not understand this technology, there will be no problem of being unable to touch the device because the detection distance is too close.

[0009] As a preferred technical solution, the fixed-point network cable port is set at the center of the ceiling of each ward in the hospital, the center of the ceiling of the nurse station, and next to the desk. The length of the network cable connecting the communication module and the fixed-point network cable port is 0.3-0.5m, and the signal receiving range of the second Bluetooth module and the third Bluetooth module is 1.5-2m. This ensures that the communication module detects the nurse who is actually in the ward wearing the smart nurse badge, and will not be detected outside the ward or not detected in the ward due to installation position deviation and receiving distance problems.

[0010] As a preferred technical solution, the Bluetooth module signal connection range and infrared pyroelectric sensor signal receiving range proposed in this technical solution are technologies that can be understood by ordinary technicians in this field. The solutions are as follows: when the nurse wearing the smart nurse badge is away from the nurse station or enters the ward, when the communication module is wirelessly paired with the first Bluetooth module, the working state of the voice sound robot is the "working" state mode. When the nurse wearing the smart nurse badge is at the nurse station, when the communication module is paired with the second Bluetooth module, the working state of the voice sound robot is the "silent" state mode.

[0011] In particular, in order to enable ordinary technicians in this field to have a more comprehensive understanding of the specific functions of the system and device, the "working" state mode is provided with a voice reminder mode and an AI voice interaction mode; wherein the voice reminder mode includes voice broadcast, message storage and remote vibration reminder through the vibration module.

[0012] In addition, the wireless connection method between Bluetooth modules and the connection method between WiFi are within the scope that ordinary technicians in the field can understand and therefore are not described in detail.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-8, an intelligent nurse device based on AI voice control, the intelligent nurse device includes a voice sound robot 7 with AI voice recognition capability and an infrared pyroelectric sensor 2, an intelligent nurse card 8 mounted on the nurse work card in a card-connected manner, a communication module 15 with a Bluetooth module and an edge computing device 12 with AI voice processing capability, a cloud platform computing server 11 with AI voice processing and AI voice training capabilities, a computer room 13 and a nurse station 18; wherein the voice sound robot 7 is provided with a CPU 6, a voice recognition sensor 1, an infrared pyroelectric sensor 2, a voice playback module 3, a WiFi module 4 and a second Bluetooth module 5; the intelligent nurse card 8 is provided with a third Bluetooth module 9 and a vibration module 10;

[0028] Among them, the edge computing device 12 is arranged in a computer room 13 and the terminal is connected to the cloud platform computing server 11 through an optical fiber. A switch and a local area network transmission system 14 are arranged in the computer room 13. The local area network transmission system 14 includes a fixed network cable port arranged in the hospital through a network cable. The switch is connected to the edge computing device 12 and the local area network transmission system 14 respectively through a network cable. The communication module 15 is connected to the fixed network cable port through a network cable. The voice audio robot 7 is arranged on the nurse station 18 and is connected to the fixed network cable port through a network cable. The smart nurse card 8 is connected to the communication module 15 or the voice audio robot 7. When connected, the voice audio robot 7 forms two different working state modes.

[0029] With the help of the above technical solution, the present invention is based on AI voice interaction. Usually, the hospital's local area network transmission system 14 is normal, the communication module 15 is working normally, the WiFi module 4 and the second Bluetooth module 5 of the intelligent voice audio robot 7 are in normal working state, and the intelligent voice audio is connected to the Internet at any time through the connection between the WiFi module 4 and the WiFi. The nurse puts the smart nurse card 8 in the system on the nurse's ordinary work card. Due to the function of being recognized and identified by the third Bluetooth module 9, the nurse has the ability to be recognized by the system signal.

[0030] The AI ​​voice nurse robot is fixedly placed at the nurse station 18, and is normally powered to maintain normal operation 24 hours a day. The WiFi module 4 is connected to the hospital's WIFI network, and can maintain normal communication with the edge computing device 12 and the cloud platform computing server 11. The Bluetooth module is used to identify whether the smart nurse card 8 is approaching. The voice recognition sensor 1 is used to receive external sound recognition input in real time. The infrared pyroelectric sensor 2 is used to detect in real time whether someone is approaching the nurse station 18 for consultation. The voice playback module 3 is used to play the response voice information after AI recognition processing.

[0031] When the nurse works normally at the nurse station 18, the second Bluetooth module 5 of the AI ​​voice nurse robot detects the communication module 15 of the smart nurse card 8, automatically determines that the nurse is at the nurse station 18, and then the third Bluetooth module 9 is automatically paired with the second Bluetooth module 5, and the voice sound robot 7 automatically switches to the "silent" state mode. At this time, only the voice recognition module accepts external voice input, no other special processing is performed, and no work of replacing the nurse is performed.

[0032] When the nurse leaves the nurse station 18, the communication module 15 in the ward detects the smart nurse card 8 and automatically determines that the nurse is not at the nurse station 18. At this time, when the third Bluetooth module 9 is wirelessly paired with the communication module 15, the working state of the voice sound robot 7 is the "working" state mode, and the second Bluetooth module 5 corresponding to the position of the communication module 15 locates the current position of the nurse, so that when a patient or family member comes for consultation, the real-time voice broadcast of the real-time position is convenient. In this state, the "working" state mode of the voice sound robot 7 also has a "ready" working mode at any time. And continue to use the infrared pyroelectric sensor 2 to determine whether there are patients or family members coming for consultation. If there is no one, continue to maintain the "silent" state mode. Thereby ensuring timely reception of consultations from patients or family members, avoiding affecting the patient's experience, reducing the burden on nurses, and improving hospital work efficiency.

[0033] If the infrared pyroelectric sensor 2 in the AI ​​voice nurse robot recognizes that someone is coming for consultation, the AI ​​voice nurse robot will immediately switch to the "working" state mode and periodically broadcast the preset voice of the program, such as a similar voice: "Hello, I am an AI nurse. Nurse Li has temporarily left and may have gone to ward XX. If you have an emergency, you can also leave me a message first, and I will convey it to Nurse Li immediately." Nurse Li and ward XX, these voice information are judged by the system in different scenarios, and AI voice training is performed to obtain different voice contents. For example, it can be "... Nurse Zhao temporarily left and may have gone to ward XX..." In addition to playing sounds, the AI ​​voice nurse robot is also constantly running the voice recognition module to receive the patient's conversation content and record it.

[0034] If the AI ​​voice nurse robot is in the "working" state mode, it will extract and train the received voice content to give intelligent answers to patients' questions. For example, if a patient asks, "Where is the hospital cafeteria?", the AI ​​voice nurse robot will feedback to the patient similar information through the edge computing device 12 and the cloud platform computing server 11: "Hello, our hospital cafeteria is in Building XX, just to the north of our building. You can consult the cafeteria work phone number XXXXXX". For example, if a patient asks, "What is the weather like today?", the AI ​​voice nurse robot will answer as follows: "Hello, the weather is sunny today, and the temperature is between XX and XX degrees."

[0035] In the "working" mode, once the AI ​​voice nurse robot has answered the patient's question, it will immediately transmit the information to the smart nurse card 8 carried by the nurse through the WIFI network system with Bluetooth processing capabilities, and trigger the vibration module of the smart nurse card 8 to vibrate and remind. After the nurse receives the vibration reminder, she knows that there is a patient at the nurse station 18 who needs help, and she will return to the nurse station 18 as soon as possible. After the nurse returns to the nurse station 18, the AI ​​voice nurse robot can repeat the questions asked by the patient just now, and the nurse can handle them one by one without rushing.

[0036] In addition, in one embodiment, the infrared pyroelectric sensor 2 includes a transmitter and a receiver, and the signal receiving range of the transmitter and the receiver is 0.2-0.4m. Among them: the transmitter is used to emit infrared rays with heat, which can receive within the range of 0.2-0.4m during operation. Once it is irradiated to the human body, it will be reflected. The receiver receives the energy of the reflected ultraviolet rays. Due to the energy difference calculated, it begins to judge that someone comes to consult, and sets the receiving range of 0.2-0.4m. In order to ensure that the person being detected is indeed close to the nurse station for consultation, and to ensure that he is basically close to the nurse station, not only will the inadvertent passerby not be detected at a too far distance, causing information misjudgment and affecting the work of the nurse, but also the person who does come to consult at a close distance will not deliberately get close to the voice audio robot, and even for people who do not understand this technology, the problem of being unable to touch the device will not occur because the detection distance is too close.

[0037] In addition, in one embodiment, the fixed-point network cable port is set at the center of the ceiling of each ward in the hospital, the center of the ceiling of the nurse station 18, and next to the desk. The length of the network cable connecting the communication module 15 and the fixed-point network cable port is 0.3-0.5m. The position of the nurse can be accurately located through the spatial position setting to avoid the situation that the Bluetooth signal can still be connected when passing through a certain ward, resulting in false reporting and misreporting of the position information. The signal receiving range of the first Bluetooth module 17, the second Bluetooth module 5, and the third Bluetooth module 9 is 1.5-2m. The communication module detects the nurse who is actually in the ward wearing the smart nurse card, which will not be caused by the problem of installation position deviation and receiving distance. It can be achieved within the existing maximum area of ​​the common, and the problem of detection outside the ward or undetectable in the ward can be achieved, ensuring both no wrong connection and uninterrupted connection.
