[0002] Medical restraints are specialized medical devices used clinically to restrict patients' limb movement. They are primarily used to prevent patients with impaired mental consciousness, those who are unconscious after anesthesia, or those who may interfere with treatment or cause harm to themselves or others. Medical restraints can be categorized into trunk restraints and limb restraints, depending on the area being restrained, and restraints for different areas are not interchangeable.

[0003] Traditional medical restraints use wide bandages, which are first bound to the patient's torso or limbs before being secured to the bed or support frame to restrict patient movement. To improve ease of use and restraint effectiveness, medical restraints with Velcro, buckles, or magnetic closures are now available for easy installation and removal. While existing restraints can secure patients, they often lack a snug fit, leading to loosening and eventual failure of the restraint. Furthermore, the need for adjustment to fit the patient's body is cumbersome and increases the workload for healthcare workers.

The restraint strap 2 is wrapped around the retraction and extension assembly, with one end connected to the assembly and the other end extending out of the support cylinder 1. The end of the restraint strap 2 extending out of the support cylinder 1 wraps around the limb to be secured and then connects to the middle portion of the restraint strap 2 extending out of the support cylinder 1 via the snap-fit ​​assembly. The retraction and extension assembly is controlled by the limiting mechanism 3 to change the fixation state and extension length of the restraint strap 2, achieving effective fixation of the patient's limb and reducing the occurrence of gaps or loosening. Furthermore, the extension length of the restraint strap 2 can be adjusted to suit patients of different body sizes or different body parts.

[0023] Preferably, a set of Velcro straps 15 are installed at the bottom of the support cylinder 1. The support cylinder 1 is interactively installed at the bed rail or other positions through the Velcro straps 15 to achieve overall fixed installation of the easy-to-wear protective restraint strap.

[0024] For details, see Figure 2 The snap-fit ​​assembly includes an upper snap-fit ​​plate 4, a lower snap-fit ​​plate 5, two sets of threaded rods 6, and a movable ring 7. The top of the upper snap-fit ​​plate 4 is fixedly connected to the end of the restraint strap 2. The upper snap-fit ​​plate 4 and the lower snap-fit ​​plate 5 clamp the restraint strap 2 from the upper and lower sides, respectively, and the restraint strap 2 can slide between the upper snap-fit ​​plate 4 and the lower snap-fit ​​plate 5. The upper snap-fit ​​plate 4 and the lower snap-fit ​​plate 5 are detachably connected by the two sets of threaded rods 6 and the movable ring 7. Specifically, the threaded rod 6 passes through the upper snap-fit ​​plate 4 and the lower snap-fit ​​plate 5 from the top of one end of the upper snap-fit ​​plate 4, and the movable ring 7 is threadedly connected to the threaded rod 6 from the bottom of the lower snap-fit ​​plate 5. In use, first, the restraint strap 2 is wrapped around the patient's limb, and then the snap-fit ​​assembly is assembled and installed using the threaded rods 6 and the movable ring 7. The restraint strap 2 is fixedly wrapped around the outside of the patient's limb by the snap-fit ​​assembly, which can ensure that the restraint strap 2 fits the body closely, reduce the possibility of gaps and loosening, and the installation operation is simple and quick.

[0025] See Figure 3 The retraction assembly includes a retraction tube 8, with a restraint strap 2 wrapped around the outside of the retraction tube 8, and one end of the restraint strap 2 connected to the retraction tube 8. The retraction tube 8 is rotatably mounted inside the support tube 1. A coaxial knob 10 is fixedly mounted on one end of the retraction tube 8. The knob 10 is located outside the support tube 1, and the user can retract the restraint strap 2 by rotating the knob 10.

[0026] See Figure 3 and Figure 4 The end of the take-up and release tube 8 away from the knob 10 has a toothed groove 9. The limiting mechanism 3 acts on the toothed groove 9 to switch the rotation and fixed states of the take-up and release tube 8. The limiting mechanism 3 includes a fixed tube 11, a toothed rod 12, a pull ring 13, and a return spring 14. The fixed tube 11 is installed in conjunction with the support tube 1, and the fixed tube 11 is installed at the end of the take-up and release tube 8 with the toothed groove 9. The toothed rod 12 is slidably installed in the fixed tube 11, and the toothed rod 12 is aligned with the toothed groove 9. One end of the toothed rod 12 is slidably inserted into the toothed groove 9, and the other end of the toothed rod 12 is fixedly connected to the pull ring 13, which is located outside the support tube 1. The return spring 14 is arranged around the toothed rod 12. When the pull ring 13 is pulled outward, the toothed rod 12 is disengaged from the tooth groove 9, and the return spring 14 is compressed at the same time. At this time, the retractable tube 8 can rotate freely, and the user can pull the restraint strap 2 to extend the service length. After the pull ring 13 is stopped, the toothed rod 12 is reset under the action of the return spring 14. The toothed rod 12 is inserted into the tooth groove 8 again, preventing the retractable tube 8 from rotating. At this time, the restraint strap 2 cannot be pulled or retracted, thus forming a fixed limit on the restraint strap 2.

[0027] When using the easy-to-wear protective restraint strap, first pull the pull ring 13 outward to disengage the toothed bar 12 from the toothed groove 9. At this time, the retractable tube 8 is in a free-rotating state. By rotating the knob 10 and pulling the restraint strap 2, the length of the restraint strap 2 extending out of the support tube 1 can be adjusted to suit different usage needs. Then, release the pull ring 13, and the toothed bar 12 will return to its original position under the action of the return spring 14. The toothed bar 12 will then re-insert into the toothed groove 8, and the retractable tube 8 will be in a fixed state. Next, place the support tube 1 on one side of the bed rail and fix the support tube 1 to the bed rail with Velcro 15. Then, wrap the restraint strap 2 around the outside of the body part of the patient that needs to be fixed. Move the front end of the restraint strap 2 to adjust the restraint range so that the restraint strap 2 fits the patient's body. Then, align the upper clamping plate 4 and the lower clamping plate 5, and then rotate the two threaded rods 6 simultaneously to make the upper clamping plate 4 and the lower clamping plate 5 engage and fix on the outside of the restraint strap 2. The movable ring 7 prevents the two clamping plates from separating, thus completing the restraint and fixation operation for the patient. The easy-to-wear protective restraint belt is simple and quick to install and adjust, which helps improve efficiency and reduce the workload of medical staff.
