[0038] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0039] See also Figure 1-8 As shown, a restraint belt with intelligent monitoring and prompting functions, the restraint belt with intelligent monitoring and prompting functions includes:

[0040] A limb restraint component 1, wherein a traction limiting component 2 is fixedly connected to one side of the limb restraint component 1;

[0041] The traction restriction component 2 includes a traction belt 204 and an elastic winding mechanism, and the traction belt 204 is fixedly connected to the limb restraint component 1;

[0042] A prompting component 3, which is fixedly disposed on one side of the traction limiting component 2 and is connected to the traction limiting component 2, and is used to convert the displacement of the traction belt 204 into mechanical transmission;

[0043] The fixing component 4 is fixedly arranged on the outer surface of the traction limiting component 2 and is used to fix the traction limiting component 2.

[0044] Through the above technical solution, when restraining critically ill patients, if the patient's wrist or arm suddenly moves beyond a certain range, a timely reminder can be issued to prompt the medical staff in charge to pay attention to care and take effective measures in time to avoid self-injury accidents during extubation. This has important practical significance for the safety of medical staff in charge and patients.

[0045] The limb restraint assembly 1 includes a restraint sleeve 101 and a fixing structure. The outer surface of the restraint sleeve 101 is provided with a fixing structure, and the fixing structure is used to fix the restraint sleeve 101 to the patient's wrist;

[0046] The fixing structure includes a first Velcro layer 102, a fixing strap 103 and a second Velcro layer 104. The first Velcro layer 102 is fixedly arranged on the outer surface of the restraint sleeve 101, and the fixing strap 103 is fixedly arranged at one end of the restraint sleeve 101. The second Velcro layer 104 is fixedly arranged on the fixing strap 103. The first Velcro layer 102 and the second Velcro layer 104 cooperate with each other on the hook / loop surface to achieve wrist adjustment and fixation.

[0047] The elastic winding mechanism includes a fixed circular shell 201, a rotating shaft 202, a winding roller 203, a side shell 205 and a spring spring 207. The rotating shaft 202 is rotatably connected to the inner cavity of the fixed circular shell 201, and the winding roller 203 is fixedly connected to the arc-shaped wall of the rotating shaft 202. A traction belt 204 is wound on the winding roller 203, and one end of the traction belt 204 passes through the inner cavity wall of the fixed circular shell 201 and extends outside the wall.

[0048] The outer wall of the fixed circular shell 201 is fixedly connected to the side shell 205, and the inner cavity of the side shell 205 is rotatably connected to a rotating column 206, and the rotating column 206 is fixedly connected to one end of the rotating shaft 202, and the arc-shaped wall of the rotating column 206 is fixedly connected to one end of a clockwork spring 207, and the other end of the clockwork spring 207 is fixedly connected to the arc-shaped inner wall of the side shell 205. Through this technical solution, when the patient's wrist moves, the traction belt 204 drives the winding roller 203 to rotate, so that the clockwork spring 207 stores energy to generate progressive resistance, thereby limiting the range of movement.

[0049] The prompt assembly 3 includes a fixed cylinder 301, a prompter 306 and a mechanical transmission structure. The fixed cylinder 301 is fixedly arranged on the side wall of the fixed circular shell 201, and the prompter 306 is fixedly installed on one end of the fixed cylinder 301;

[0050] The mechanical transmission structure includes a guide ridge 302, a contact slider 303, a contact switch 304, and a threaded rod 305. The contact slider 303 is slidably connected to the inner cavity of the fixed cylinder 301. The guide ridge 302 is fixedly connected to the inner cavity wall of the fixed cylinder 301. The outer wall of the contact slider 303 is provided with a sliding groove that cooperates with the guide ridge 302.

[0051] The contact switch 304 is fixedly arranged at the end of the inner cavity of the fixed cylinder 301, and the trigger pressure is 2N. A threaded rod 305 is rotatably connected to the inner cavity of the fixed cylinder 301. One end of the threaded rod 305 is fixedly connected to one end of the rotating shaft 202. The threaded rod 305 passes through the contact slider 303 and is threadedly engaged with the contact slider 303. According to this technical solution, when the wrist movement exceeds the safety threshold, the rotating shaft 202 drives the threaded rod 305 to rotate, pushing the contact slider 303 to move and triggering the contact switch 304, activating the indicator 306 to alarm;

[0052] The fixing assembly 4 includes a rectangular fixing seat 401, a limiting slider 402, a limiting claw 403, a double-helix screw 404 and an adjusting knob 405. The rectangular fixing seat 401 is fixedly arranged on the outer surface of the fixed circular shell 201. An inner cavity is arranged inside the rectangular fixing seat 401. The limiting slider 402 is slidably connected to both sides of the inner cavity of the rectangular fixing seat 401. The end of the limiting slider 402 is fixedly connected to the limiting claw 403.

[0053] A double-helical screw 404 is rotatably connected in the inner cavity of the rectangular fixing seat 401. Both ends of the double-helical screw 404 pass through the two limit sliders 402 and are threadedly engaged with the limit sliders 402. One end of the double-helical screw 404 is fixedly connected to an adjustment knob 405. According to the present technical solution, rotating the adjustment knob 405 drives the double-helical screw 404 to rotate, so that the limit claws 403 on both sides are synchronously extended and retracted, and can be clamped and fixed on the bed guardrail.

[0054] Furthermore, the restraint sleeve 101 is embedded with a monitoring terminal 5, which includes:

[0055] First identity recognition module 501, force sensing module 502, posture sensing module 503, first Bluetooth communication module 504;

[0056] The supporting medical terminal 6 is a smart watch, which has built-in: a second identity recognition module 601, a data processing module 602, a voice prompt module 603, and a second Bluetooth communication module 604.

[0057] When implementing monitoring, medical staff use the smart watch to scan the unique identification code on the first identity recognition module 501 to complete the device binding and patient identity association;

[0058] During monitoring, the force sensing module 502 collects the patient's wrist tension data in real time, which can be collected using a strain gauge sensor with a sampling rate of 0.5kHz. At the same time, the posture sensing module 503 monitors the wrist flexion and extension angles through a six-axis inertial sensor. The data from both sensors are encrypted and transmitted to the smart watch via the first Bluetooth communication module 504.

[0059] In a typical application scenario, when the wrist tension of a 75kg patient suddenly increases to 55N, for example, when attempting to stand up from the bed, and the wrist flexes to 50°, such as when simulating a tube-grabbing action, the data processing module 602 determines abnormal behavior within a certain period of time based on a preset algorithm and immediately triggers an alarm.

[0060] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art.

[0061] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
