Description

Technical Field

[0001] The present invention relates to the technical field of surgical medical diagnosis, and in particular to an intelligent wearable device for intervention of skin self-injury. Background Art

[0002] Non-suicidal self-injury (NSSI) is defined as the direct and intentional destruction of one's own bodily tissues without suicidal intent. The incidence of NSSI is particularly high among adolescents with major depressive disorder (MDD). It is not only a common comorbidity of depression but also a distinct clinical issue requiring attention and intervention. This behavior has addictive mechanisms, requiring effective intervention strategies and proactive intervention. Based on the skin-brain axis theory, NSSI behavior can be monitored and intervened through skin monitoring and intervention, preventing NSSI behavior and capturing emotional changes before and after NSSI behavior.

[0003] When monitoring for self-injury behavior, multiple sensors are usually used for collaborative perception. The sensors used to monitor gestures monitor the patient's hand movements in real time. The built-in algorithm identifies self-injury-related gesture patterns such as repeated picking, pulling, and prying with tools. Specific gestures are detected and corresponding intervention measures are initiated. Heart rate sensors, skin conductance sensors, etc. monitor the patient's physiological indicators in real time to assist in judging the patient's emotional state. When an abnormal increase in the patient's heart rate or changes in skin conductivity are detected, the risk of self-injury behavior is assessed in combination with gesture monitoring data.

[0004] During daily self-harm behavior monitoring, only monitoring is performed without taking corresponding intervention measures to alleviate the patient's emotions and behaviors. In addition, the patient may fall into strong emotional fluctuations and may remove the device and unconsciously scratch or tear the device. At this time, the patient's awareness of his own movements is reduced. Some patients may regard the device as a "monitoring tool", feel controlled, and trigger a rebellious removal in order to smoothly satisfy the self-harm behavior, making the device easy to damage or the violent swinging movement during self-harm will cause the device to loosen and fall off, resulting in the device being unable to help the patient. For monitoring and intervention of non-suicidal self-harm behaviors, a smart wearable device for skin self-harm intervention is proposed. Summary of the Invention

At this time, the patient's awareness of his own movements is reduced, and some patients may regard the device as a "monitoring tool", which creates a sense of being controlled and triggers resistance to removal in order to smoothly satisfy the self-injury behavior, making the device easy to be damaged or the violent swinging action during self-injury will cause the device to loosen and fall off, resulting in the device being unable to help the patient and the problem of monitoring and intervening in non-suicidal self-injury behaviors.

The hook 26 squeezes the telescopic rod 24 and the elastic element 2 25 due to the magnetic force, and re-contacts and fixes with the snap-in slot 27, which is convenient for the patient to wear and remove by himself, and pushes the strap 201 into the shell 1 to adjust the loop length of the strap 201. After the adjustment is completed, the device automatically starts the micro piezoelectric pump 14 to inflate the airbag 204 through pressure sensor feedback, fine-tunes the tightness, ensures that the device fits firmly on the skin, and is convenient for the patient to adjust the wearing comfort. The device monitors the patient's hand movements in real time through the multi-module sensor 12 and the gyroscope 13, and recognizes self-injury-related gesture patterns such as repeated pulling, pulling hard, and prying with tools through the built-in algorithm. It detects specific gestures and initiates corresponding intervention measures. The heart rate sensor, skin charge sensor, etc. monitor the patient's physiological indicators in real time to assist The patient's emotional state is judged, and abnormal increase in the patient's heart rate and changes in skin conductivity are detected. When it is judged that self-harm behavior occurs, the micro electromagnetic suction cup 11 at the right end of the strap 201 is started, and at the same time, the micro piezoelectric pump 14 is started to inflate the airbag 204 through the trachea 208, so that the strap 201 expands and reduces the inner circle radius, tightening the arm to prevent the device from loosening and detaching under large-scale movements. When the airbag 204 is inflated, the moving rope 207 is subjected to the change of the outer circle of the airbag 204 to generate a tensile force, so that one end of the moving rope 207 pulls the fixed shaft 606 connected to one side of the strong magnetic card block 22 to move the right end of the strap 201 toward the inside of the housing 1, and the fixed shaft 606 drives the gear 603 to move, and the gear 603 rotates through the spur rack 602, and the gear 603 drives the shaft sleeve 604 to rotate. The shaft sleeve 604 reels the moving rope 207 during the movement of the strap 201, maintains the tension of the moving rope 207, and prevents the moving rope 207 from becoming disordered. The movement of the shaft sleeve 604 simultaneously drives the contact ring 605 to move and contact the energized contact electrodes 607 at different positions, and sends out an electrical signal to know which adjustment hole 209 position the strap 201 has moved to, so as to facilitate closing the micro electromagnetic suction cup 11 and fix the strap 201 with the retaining component 7. For different degrees of self-injury behavior, the airbag 204 adapts to the expansion and adjusts the degree of contraction in mild cases to prevent the device from loosening and falling off. It is impossible to effectively monitor the actual data for judgment. By activating the microporous atomizer 304 to release soothing aroma molecules, the patient can be helped to relieve tension. By activating the vibration motor 32, mild vibration is generated.Tactile stimulation is used to distract the patient's attention and interrupt the self-harm behavior; in moderate cases, when the patient is detected pulling the device, the airbag 204 reaches the maximum expansion degree, making the device fit more firmly on the skin and preventing the patient from removing it easily. At the same time, the airbag 204 cushions the internal circuit and electrodes of the strap 201 to reduce the risk of damage and ensure normal operation. At the same time, preset soothing voices are played, such as soothing music, calm guidance, etc., and the vibration motor 32 produces rapid vibrations to further soothe the patient's emotions and guide him to stop the self-harm behavior; in severe cases, when it is detected that the patient is using tools to pry the device, and combined with physiological indicators to determine that the patient is in an emotional outburst state, the device contacts the pre-set emergency contacts such as family members and medical staff through the wireless network integrated on the PCB control board 10, and sends the patient's location information and current status so that relevant Personnel take timely measures to intervene. When the patient releases the device through the display screen 4 and the control button, there is an operation that requires pressing the membrane button sheet 5 in sequence to release the tightening, distract the patient's attention, and help the patient calm down and stop self-harming behavior. The device adopts adjustable fixation through the contraction component 2 and the winding movement component 6, which is convenient for patients to wear and remove by themselves. After the device is worn, the tightness can be automatically fine-tuned according to the size of the patient's limbs to ensure that the device fits firmly on the skin. When self-harming behavior occurs, the strap can be quickly tightened to prevent the strap from loosening due to violent movements, resulting in inaccurate monitoring or device falling off. It also prevents patients from arbitrarily removing the device due to emotional fluctuations, resulting in the inability to intervene in the patient's self-harm behavior. Different intervention measures are taken according to the degree of self-harm to prevent the patient from engaging in self-harming behavior.
