[0035] As shown in the drawingsFigure 1 To the attached Figure 8 As shown:

[0036] Embodiment one:

[0037] The application provides a protective restraint belt, which comprises two belts 1, one side of the belt 1 is provided with a fastening mechanism 3, the fastening mechanism 3 comprises a flexible shell 301, one side of the flexible shell 301 is fixedly connected with one side of the adjacent belt 1, the other side of the belt 1 is fixedly connected with a clamping tooth bar 302, one side of the clamping tooth bar 302 extends through the inner cavity of the adjacent flexible shell 301 to one side of the flexible shell 301, the inner cavity of the flexible shell 301 is vertically provided with a tooth column 304, and the outer circle of the tooth column 304 is connected with one side of the adjacent clamping tooth bar 302 through clamping tooth engagement.

[0038] The inner surface wall of the belt 1 is fixedly connected with an adaptive air bag 4, one side of the adaptive air bag 4 is fixedly connected with a pressure sensor 8, and the other side of the adaptive air bag 4 is fixedly connected with an infrared multifunctional sensor 9.

[0039] A plurality of telescopic restraint mechanisms 2 are arranged between the two belts 1, the telescopic restraint mechanism 2 comprises a flexible telescopic belt 201, both ends of the flexible telescopic belt 201 are provided with fixed blocks 204, the inner cavities of the fixed blocks 204 are rotatably connected with receiving columns 203, one side of the receiving column 203 is fixedly connected with a stress block 202, and one side of the stress block 202 is fixedly connected with one end of the adjacent flexible telescopic belt 201.

[0040] One side of the outer surface wall of the belt 1 is provided with a plurality of connecting mechanisms 7, the connecting mechanism 7 comprises a mounting seat 701, one side of the mounting seat 701 is fixedly connected with one side of the adjacent belt 1, one side of the mounting seat 701 is provided with a connecting groove 702, and one end of the fixed block 204 is inserted into the inner cavity of the adjacent connecting groove 702.

[0041] Working principle: In actual use, the two sleeves 1 of the protective restraint belt are respectively wrapped around the two upper limbs such as wrists or the two lower limbs such as ankles of the patient to achieve symmetrical and stable restraint of the main active joints; all key components in the entire device that come into contact with the human body or bear mechanical load, including the sleeve 1, the flexible stretchable belt 201, the flexible shell 301, and the adaptive air bag 4, are made of medical-grade silicone mixed with high-elasticity breathable fiber, which has excellent biocompatibility, low allergenicity, softness, skin-fitting property, and long-term wearability, effectively reducing the risk of skin irritation and allergy; when emergency restraint is needed, the medical staff inserts the clamping tooth bar 302 fixed at the end of one sleeve 1 into the inner cavity of the flexible shell 301 in the fastening mechanism 3 provided on the adjacent sleeve 1, and the tooth surface of the clamping tooth bar 302 engages with the internally vertically arranged tooth column 304 after penetrating the flexible shell 301, then the servo motor 303 is started, the output shaft of which drives the tooth column 304 to rotate, thereby driving the clamping tooth bar 302 to wind inwards or release outwards, achieving automatic and accurate adjustment of the circumference of the sleeve 1, so that the restraint tightness is moderate and can be dynamically controlled; at the same time, the adaptive air bag 4 integrated on the inner surface wall of the sleeve 1 closely fits the patient's skin, the pressure sensor 8 connected to one side of the adaptive air bag 4 continuously and real-timely monitors the pressure value of the local tissue, and transmits the data to the control system, once the detected pressure exceeds the critical value of the preset safety threshold value that may cause capillary occlusion, the system immediately instructs the servo motor 303 to operate in reverse, moderately loosens the clamping tooth bar 302, and reduces the compression strength, while the infrared multifunctional sensor 9 connected to the other side of the adaptive air bag 4 synchronously collects subcutaneous blood flow signals for analyzing pulse waveform, blood oxygen saturation, and microcirculation perfusion state, providing objective physiological basis for clinical judgment of whether there is blood circulation disorder; after completing the basic encircling restraint, a number of stretchable restraint mechanisms 2 are installed between the two sleeves 1 to enhance the overall stability, the specific operation is to insert the fixed blocks 204 at both ends of the flexible stretchable belt 201 into the connecting grooves 702 in the linking mechanisms 7 on the outer surface walls of the corresponding sleeves 1, at this time, the spring dampers 704 in the structure grooves 703 on both sides of the mounting seat 701 push the flat plates 705 to move outward, so that the pentagonal insertion columns 707 are embedded in the insertion holes 205 opened on both sides of the fixed blocks 204, forming a firm mechanical lock, if quick disassembly is needed, only the knob 706 exposed on the side wall of the mounting seat 701 needs to be turned, which drives the flat plate 705 to overcome the elastic force of the spring damper 704 to retract, so that the pentagonal insertion column 707 is separated from the insertion hole 205, thereby realizing tool-free quick separation.Furthermore, the outer wall of the sleeve 1 is also provided with a plurality of docking seats 6 and matched buckle ring mechanisms 5, wherein the metal rod 501 is connected with the docking seat 6 through a rotating shaft, and the two lateral rods 502 are rotatably installed with winding outer frames 503, and the rope belt 504 is wound and connected between the two winding outer frames 503. In use, the free end of the rope belt 504 can be extended and tied to the bed rail, a fixed ring or other external anchor point, which is used to assist in fixing other areas of the upper or lower limbs of the patient, such as the forearm, the lower leg or the elbow, so as to limit the dangerous actions such as swinging arms and kicking, and the magnet block 506 at the end of the rope belt 504 is inserted into the clamping groove 505 on the metal rod 501 in the use state, which ensures firm and reliable connection through the dual effects of physical insertion and magnetic attraction, effectively prevents the rope belt 504 from accidentally slipping off or being forcibly pulled out of the buckle ring mechanism 5 when the patient struggles violently, thereby improving the anti-escape ability and clinical safety of the overall restraint system;

[0042] The scheme is aimed at the risk of local skin compression, capillary circulation disorder, even pressure sores, nerve compression injury and other risks caused by the lack of pressure regulation ability of traditional cotton or ordinary synthetic fiber restraint belts. The scheme uses medical grade silicone mixed with breathable fiber as the main material, and combines a closed-loop monitoring feedback system composed of self-adaptive air bag 4, pressure sensor 8 and infrared multifunctional sensor 9, which can sense the pressure and blood flow state of the restraint part in real time, and automatically trigger the servo motor 303 to adjust the tightness when abnormal, fundamentally avoiding tissue ischemia and irreversible damage caused by long-term compression; In view of the problems of complicated operation, slow response, and difficult quantification of tightness caused by the existing restraint methods relying on manual lacing, magic tape or plastic buckle, the electric meshing transmission system composed of servo motor 303, tooth column 304 and clamping rack 302 in fastening mechanism 3 realizes one-key automatic tightening and accurate tightness control, greatly shortens the emergency operation time, eliminates human judgment error, and ensures the standardization and safety of each restraint; In view of the problem that the patient's violent struggle in acute agitation state is easy to cause the restraint structure to loosen or fail, the flexible extension belt 201 in the telescopic restraint mechanism 2 is provided with elastic buffering capacity, which can absorb impact energy, and its two ends are connected through the fixed block 204 and the five-angle insertion column 707 and insertion hole 205 in the connection mechanism 7. The spring damper 704 realizes self-locking quick connection, which not only ensures the connection strength, but also is convenient for quick disassembly; At the same time, the buckle mechanism 5 connects other parts of the limbs with external fixed points through the rope belt 504, which expands the restraint dimension, and the magnetic attraction and insertion composite locking structure of the magnet block 506 and the clamping groove 505 improves the anti-escape reliability of the end of the rope belt 504, avoiding the interruption of restraint caused by the failure of single binding; Overall, the device not only takes into account the comfort and safety in material, but also combines intelligent sensing, automatic adjustment and multi-point fixing strategy in function, effectively overcoming the inherent defects of traditional restraint belts in poor comfort, low operation efficiency and insufficient safety, realizing the technical leap from static passive restraint to dynamic active monitoring plus self-adaptive adjustment plus multi-dimensional stable restraint.
