Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical technology, and in particular to an intelligent pain assessment device. Background Art
[0002] Pain is an unpleasant feeling and emotional experience associated with actual or potential tissue damage, or an experience similar to this, and is listed as the fifth vital sign. Postoperative pain is the most common and most urgent acute pain in clinical practice, which can cause various complications and affect the patient's postoperative recovery; pain is one of the most common and unbearable symptoms in cancer patients, significantly affecting patients' daily activities, self-care ability, social interaction and overall quality of life; chronic non-cancer pain often leads to functional impairment, depression and sleep disorders in patients.
[0003] Pain assessment is the basis of pain treatment, and appropriate and accurate pain assessment is the prerequisite for ensuring the quality of pain management. Since pain is an individual's subjective feeling, for patients who are able to communicate, self-reporting is the gold standard for pain assessment in clinical practice. Currently, the commonly used pain assessment tools in clinical practice, such as digital rating scales, visual analog rating scales, and verbal rating scales, are all subjective pain assessment tools for self-reporting by patients, but self-reported pain scores are easily affected by many factors such as the patient's physiological, psychological, cultural background, and living environment. For patients who cannot communicate verbally and non-verbally, assessment tools such as behavioral pain scales are needed, but behavioral pain assessment scales usually rely on medical staff to observe the patient's facial expressions, body movements, and other indicators to complete. Therefore, it is necessary to explore objective assessment tools for pain to minimize patient reporting bias and medical staff's assessment bias.
[0004] An intelligent pain management method and system based on facial expression recognition with application number 202310499266.4 includes the following steps: S1, collecting facial videos at different pain levels; S2, extracting facial image data from the collected facial videos; S3, establishing an AI pain assessment model through deep learning to assess the degree of facial pain;
[0005] A pain assessment method, system and device based on pupil changes with application number 202311550989.9 includes obtaining an eye image; inputting the eye image to a segmentation network for segmentation to obtain a pupil segmentation image; inputting the eye image and the pupil segmentation image to a feature fusion network for feature fusion to obtain a fusion feature; and evaluating based on the fusion feature to obtain a pain score.
[0006] However, whether it is using facial recognition to manage pain records or evaluating pain through changes in through-holes, accurate recognition cannot be performed due to the left and right twisting of the head during the patient's pain, that is, the recognition device cannot change position according to the change in facial orientation.

DETAILED DESCRIPTION
[0035] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0036] See also Figure 1-Figure 8 As shown, the present invention provides an intelligent pain assessment device, including an arch frame 2 with a semicircular shape and a digital display control panel 7. Both ends of the semicircular arch frame 2 are provided with a movable bracket 1 capable of supporting and moving the semicircular arch frame 2 and adjusting the height. A facial camera 3 is arranged on the semicircular arch frame 2. In actual application, the shooting direction of the facial camera 3 points to the center of the arch frame 2. The semicircular arch frame 2 is also provided with a shifting component 4 capable of driving the facial camera 3 to move thereon; during the process of the shifting component 4 driving the facial camera 3 to move on the arch frame 2, the shooting direction of the facial camera 3 is always directed to the center of the arch frame 2. The facial camera 3 is provided with a pad 12 between the inner sides of the two ends of the arch frame 2, and the pad 12 is provided with a head turning detection component 6 capable of positioning, supporting and detecting the turning of the head; when the head turning detection component 6 detects the turning of the head, the head turning detection component 6 can transmit the detected electrical signal to the digital display control panel 7, so that the digital display control panel 7 controls the shifting component 4 to drive the facial camera 3 to move to a position relative to the face.
[0037] In actual application, the pain is assessed according to the digital grading method, and the pain level is represented by 11 numbers from 0 to 10, with 0 indicating no pain and 10 indicating the most painful. The larger the number between 0 and 10, the more severe the pain. Mild pain (1-3): pain is tolerable, life is normal, and sleep is not disturbed. Moderate pain (4-6): pain is obvious, unbearable, analgesics are required, and sleep is disturbed. Severe pain (7-10): pain is severe, unbearable, analgesics are required, sleep is seriously disturbed, and may be accompanied by autonomic nervous system disorders or passive postures. The pain level is usually proportional to the bite strength of the human body, and the higher the pain level, the greater the bite strength of the teeth. People of different genders and ages have different bite strengths for the same level of pain. Therefore, when conducting an assessment, the age, gender, height and weight of the person to be assessed are input into the assessment system and the digital display control panel 7 to compare the collected big data for further and more accurate assessment.
[0038] See the instruction manual Figure 2 and 3As shown, the shift assembly 4 includes a mobile support seat 405, which is slidably arranged in the central slide groove 202 provided on the arch frame 2, a cover shell 201 is provided on the upper side of the arch frame 2, a first motor 406 is fixedly arranged in the mobile support seat 405, a gear 407 is connected to the output shaft end of the first motor 406, an arc-shaped rack 408 for engaging with the gear 407 is provided on the arch frame 2, the face camera 3 is arranged on the lower side of the mobile support seat 405, and the output end of the digital display control panel 7 is electrically connected to the input end of the first motor 406. Arc-shaped guide slide grooves 401 are provided on both side walls inside the central slide groove 202, a guide slider 402 is slidably arranged in the arc-shaped guide slide groove 401, a guide shaft 403 is fixedly arranged in the arc-shaped guide slide groove 401, a first guide slide hole for sliding through the guide shaft 403 is provided through the guide slider 402, and the guide sliders 402 are fixedly connected to the mobile support seat 405 through the brackets 404. Through the above-mentioned specific structural design, the rotation of the output shaft of the first motor 406 can drive the gear 407 to rotate. The gear 407 meshes with each other through the arc-shaped rack 408 to generate a reverse force, thereby driving the mobile support base 405 to move axially along the guide shaft 403, thereby realizing the movement of the facial camera 3 along the arc direction of the arch frame 2, and the guide shaft 403 can guide the mobile support base 405.
[0039] See the instruction manual Figure 3 As shown, the inner side of the arch frame 2 is provided with more than five sound sensors 10 evenly distributed along the arc direction thereof, the inner side of the arch frame 2 is provided with a lighting lamp 11, the output end of the digital display control panel 7 is electrically connected to the input end of the lighting lamp 11, and the output end of the sound sensor 10 is electrically connected to the input end of the digital display control panel 7. Through the above-mentioned specific structural design, each sound sensor 10 can detect the groaning sound of the patient's pain. Due to the different orientations of the patient's face, the sound intensity detected by each sound sensor 10 is also different. The orientation of the sound sensor 10 with the greatest detection intensity is even the orientation of the patient's face at this time. The lighting lamp 11 can also be feedback-controlled by the sound sensor 10. After the sound sensor 10 detects that the sound intensity reaches a certain intensity, the sound sensor 10 can turn on the lighting lamp 11 through the digital display control panel 7.
[0040] See the instruction manual Figure 2As shown, the mobile bracket 1 includes a leg 101, and more than two universal wheels 8 are arranged on the bottom side of the leg 101. The leg 101 can be moved by the universal wheels 8, so that the mobile bracket 1 can be moved to a required position according to the needs of the patient. A lifting guide slide groove 102 is opened in the middle position of the upper end of the leg 101, and a lifting slider 103 is arranged in the lifting guide slide groove 102 to slide up and down. The top of the lifting slider 103 is fixedly connected to the arch frame 2. A first electric telescopic rod 104 is fixedly arranged in the leg 101, and the push rod head end of the first electric telescopic rod 104 is fixedly connected to the lifting slider 103. Two guide rods 105 symmetrically distributed with the first electric telescopic rod 104 as the center are arranged on both sides. One end of the two guide rods 105 is fixedly connected to the arch frame 2, and the other end of the two guide rods 105 is slidably connected to the second guide slide hole opened at the corresponding position of the leg 101, and the output end of the digital display control panel 7 is electrically connected to the input end of the first electric telescopic rod 104.
[0041] See the instruction manual Figure 1 and 5As shown, the head turning detection assembly 6 includes a head support shell 601, the outer contour of the head support shell 601 is in the shape of a hemisphere, a support ear 607 is fixedly provided on the lower side of the head support shell 601, a support seat 606 is fixedly provided on the pad 12, the support ear 607 is rotatably provided on the support seat 606 through a support shaft 608, an angle sensor 609 for detecting the rotation angle of the support shaft 608 is provided on the support seat 606, and the output end of the angle sensor 609 is electrically connected to the input end of the digital display control panel 7. A second electric telescopic rod 610 is fixedly provided in the head support shell 601, when the push rod of the second electric telescopic rod 610 reaches the maximum stroke, the push rod head end of the second electric telescopic rod 610 and the shaft end of the support shaft 608 are abutted against each other, when the push rod of the second electric telescopic rod 610 reaches the minimum stroke, the push rod head end of the second electric telescopic rod 610 and the shaft end of the support shaft 608 are separated from each other, and the output end of the digital display control panel 7 is electrically connected to the input end of the second electric telescopic rod 610. A neck groove 603 is provided on one side of the head support shell 601, and two side ear notches 602 are symmetrically distributed with the neck groove 603 as the center on both sides of the head support shell 601. An inner lining 604 is provided on the inner side of the head support shell 601, and a number of ventilation grooves 605 are provided through the head support shell 601 and the inner lining 604. Through the above-mentioned specific structural design, when the patient's head lies in the head support shell 601, the patient's neck and the neck groove 603 fit each other. When the head support shell 601 initially rotates, the push rod head end of the second electric telescopic rod 610 and the shaft end of the support shaft 608 abut against each other. Therefore, when the support shaft 608 rotates, it is necessary to overcome friction. However, after the angle sensor 609 detects a certain angle of rotation, the angle sensor 609 controls the second electric telescopic rod 610 to release the abutment against the support shaft 608 through the digital display control panel 7, thereby achieving more flexible rotation of the head support shell 601. After a certain period of time when the head support shell 601 does not rotate, such as 5s-20s, the digital display control panel 7 controls the second electric telescopic rod 610 to re-abut against the support shaft 608. In actual applications, the push rod head end of the second electric telescopic rod 610 is provided with an anti-slip pad to increase the friction abutting against the end of the support shaft 608.
[0042] See the instruction manual Figure 6 As shown, a bite pressure detection structure 9 is provided on the arch frame 2, and a lifting and lifting assembly 5 for driving the bite pressure detection structure 9 to rise and fall is also provided on the arch frame 2. The bite pressure detection structure 9 includes a bite pad 901, and the outer contour of the bite pad 901 is fan-shaped. A pressure sensor 903 is provided in the bite pad 901. Positioning tooth grooves 902 are provided on the upper and lower sides of the bite pad 901, and the output end of the pressure sensor 903 is electrically connected to the input end of the digital display control panel 7.
[0043] The lifting and hoisting assembly 5 includes a lifting box 501, which is fixedly arranged on the arch frame 2 through a connecting shaft 502. A rotating chamber 503 is opened in the lifting box 501, and a rope reel 504 is rotatably arranged in the rotating chamber 503. The rope reel 504 is driven to rotate by a second motor 505 fixedly arranged in the lifting box 501. A lifting rope 506 is wound around the outer side of the rope reel 504. One end of the lifting rope 506 passes through a rope outlet hole 507 opened on the lifting box 501 and is connected to the bite pad 901.
[0044] Working principle:
[0045] Based on the tracking detection of the moving facial image, the intelligent pain assessment device is moved to the head of the bed, so that the patient's head is located directly under the arch frame 2. The first electric telescopic rod 104 of the mobile bracket 1 drives the arch frame 2 to adjust its height, so that the pad 12 and the upper surface of the bed body are in contact with each other and are level. The patient's head is resting in the head support shell 601. Through the friction between the head and the head support shell 601, and the limiting effect, the head support shell 601 can be driven to rotate left and right during the head rotation process, thereby indirectly judging the patient's facial orientation. In addition, the intensity of the groaning sound emitted by the patient in pain can be detected by each sound sensor 10. The side with greater intensity is the side where the patient's face is facing. The facial orientation of the patient is judged by combining the head turning detection component 6 and the sound sensor 10. Therefore, the digital display control panel 7 controls the displacement component 4 to drive the facial camera 3 to move to the side opposite to the patient's face, so as to shoot the patient's face, thereby using the existing database comparison method to obtain the patient's pain level. In practical applications, the assessment result can also be directly sent to the electronic medical record system.
[0046] In addition, the lifting and lowering assembly 5 drives the bite pressure detection structure 9 to descend until the bite pad 901 is close to the patient's mouth. When the patient bites the bite pad 901, a pressure sensor 903 is provided in the bite pad 901 to detect the bite force. Generally speaking, the greater the bite force, the stronger the patient's pain, thereby judging the patient's pain intensity. In addition, the bite pressure detection structure 9 can also provide safety protection for the patient's tongue to prevent biting.
[0047] By capturing the facial expression of the patient with the facial camera 3 and detecting the intensity of the bite pressure with the bite pressure detection structure 9, a more accurate pain intensity level can be obtained. In addition, the pain time and the number of pains can be recorded on the digital control panel 7. When the pain reaches a certain level, the digital control panel 7 can be remotely connected to the nurse station console to issue an automatic remote alarm to prevent the patient from fainting due to excessive pain or being unable to press the bell on his own.
[0048] In summary, based on the motion tracking detection of moving facial images, the patient's bite force and voice are evaluated to obtain the patient's precise pain intensity.
[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
