Description

Technical Field

[0001] This utility model relates to the field of medical restraint belt equipment technology, specifically a limb restraint belt used in conjunction with a hospital bed. Background Technology

[0002] Medical restraint straps are devices used to restrict the movement of a patient's limbs. They are mainly used for agitated, unconscious patients, patients at risk of self-harm or falling out of bed, or when treatment requires immobilization of a specific part of the body. Current restraint straps are secured to the patient's limbs by wrapping them around the bed and then securing them with knots. The structure itself is simple. For example, Chinese utility model patent CN217697028U discloses a limb restraint strap, including a restraint strap body and a flexible plate fixedly installed on the limb contact surface of the restraint strap body. A protective component is disposed between the restraint strap body and the flexible plate. The protective component includes multiple sets of equally spaced ball bearings. However, current restraint straps have the following drawbacks:

[0003] The current restraint straps are fixed to the hospital bed by wrapping and knotting. Because the restraint straps themselves are elastic and the surface is not rough enough, when the patient is agitated, the restraint straps may slip in the position fixed to the hospital bed, or even the knots may loosen. The fixation effect is not good and the coordination with the hospital bed is not good.

[0004] Therefore, we propose a limb restraint belt designed for use with hospital beds to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution: a limb restraint strap for use with a hospital bed, including a strap body 1, with a hospital bed fixing mechanism 2 at one end of the strap body 1. The hospital bed fixing mechanism 2 includes a horizontal plate 21, with the end of a strap 22 fixedly connected to the end of the horizontal plate 21. Multiple anti-slip soft strips 25 are fixedly embedded on the surface of the strap 22 near the horizontal plate 21. A Velcro fleece layer 23 is fixedly connected to the side of the strap 22 away from the anti-slip soft strips 25. A Velcro barb layer 24 is fixedly connected to the side wall of the side of the strap 22 away from the horizontal plate 21. When fixing to the hospital bed, the strap 22 is wrapped around the hospital bed, and then the end of the strap 22 is passed through the through-hole 26 and pulled tight so that the strap tightly wraps the fixing point of the hospital bed. Then, it is fixed by Velcro. Under the action of the anti-slip soft strips 25, the strap will not slide at the fixing point of the hospital bed.

[0024] A through-hole 26 is vertically opened on the horizontal plate 21 near the position of the strap 22. A side groove 27 is horizontally opened on the side of the through-hole 26 away from the horizontal plate 21. A pressure plate 28 is movably connected in the side groove 27. A first serrated plate 29 is fixed to one end of the pressure plate 28 near the through-hole 26. After the strap 22 is fixed to the hospital bed, the surface of the strap 22 is held in place by the first serrated plate 29. The strap 22 is fixed to the first serrated plate 29 by Velcro. The fixation effect is good, avoiding loosening and better matching with the hospital bed.

[0025] Example 2:

[0026] Please see Figure 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A soft pad layer 11 is fixedly attached to the surface of the belt body 1, and a limiting strip 12 is fixedly attached to the end of the belt body 1.

[0027] The end plate 21 of the horizontal plate 21 away from the strap 22 is fixed to the end plate 216. The top surface of the end plate 216 away from the horizontal plate 21 has a top opening 222. The top surface of the top opening 222 away from the horizontal plate 21 is horizontally rotatably connected to the horizontal shaft 217. The sleeve 218 is rotatably sleeved on the horizontal shaft 217. The bottom surface of the sleeve 218 is fixed to the second serrated plate 219. The limiting strip 12 is movably connected in the top opening 222. The second serrated plate 219 contacts the surface of the belt body 1. The second serrated plate 219 is used to lock the limiting strip 12, connecting the belt body 1 to the bed fixing mechanism 2.

[0028] A lever 221 is fixedly connected to the sleeve 218. A torsion spring 220 is fixedly sleeved inside the sleeve 218. One end of the torsion spring 220 is fixedly connected to the outer wall of the horizontal shaft 217, and the other end of the torsion spring 220 is fixedly connected to the inner wall of the sleeve 218. A limiting block 223 is fixedly connected to the top surface of the side wall of the top opening 222. The side of the second serrated plate 219 away from the horizontal plate 21 contacts the limiting block 223. The limiting block 223 restricts the position of the second serrated plate 219 to prevent the limiting strip 12 from falling off. By moving the lever 221, the second serrated plate 219 can be separated from the belt body 1, making it easy to remove the limiting strip 12 from the bed fixing mechanism 2.

[0029] A guide opening 210 is provided on the middle side wall of the side groove 27. One end of the guide rod 211 is movably connected to the guide opening 210. The other end of the guide rod 211 is fixed to the end of the pressure plate 28. A spring 212 is sleeved on the guide rod 211. One end of the spring 212 is fixed to the end of the pressure plate 28. The other end of the spring 212 contacts the side wall of the side groove 27. The elastic force of the spring 212 makes the first serrated plate 29 tightly contact the strap 22.

[0030] A limiting opening 213 is opened on the side wall of the horizontal plate 21 at the upper part of the end of the side groove 27, and a through groove 214 is opened on the side wall of the horizontal plate 21 at the lower part of the side groove 27. The through groove 214 connects to the limiting opening 213, and the through groove 214 and the limiting opening 213 connect to the side groove 27. A locking block 215 is fixedly connected to the end side wall of the pressure plate 28. The locking block 215 slides to connect the through groove 214 and the limiting opening 213. The position of the first serrated plate 29 can be adjusted by moving the locking block 215.

[0031] Example 3:

[0032] Please see Figure 1-5This is the third embodiment of the present invention, based on the above two embodiments. In use, the patient's limb is fixed by wrapping the strap 1 around it. Then, the limiting strip 12 at the end is inserted into the top opening 222. During insertion, the second serrated plate 219 rotates and opens under force. After the limiting strip 12 is fully inserted into the top opening 222, the second serrated plate 219 returns to its original position and locks the limiting strip 12 under the elastic force of the torsion spring 220. Then, the strap 22 is wrapped around the bed fixing point. The end of the strap 22 is then passed through the through opening 26 and tightened to tightly wrap around the bed fixing point. Using Velcro for fastening, the locking block 215 is moved from the limiting opening 213 to the through slot 214. Under the elastic force of the spring 212, the first serrated plate 29 locks the surface of the strap 22, completing the fixation to the hospital bed. When fixing to the hospital bed, the strap 22 is wrapped around the hospital bed, and then the end of the strap 22 is passed through the through opening 26 and tightened so that the strap tightly wraps the fixation point of the hospital bed. Then, it is fixed using Velcro. Under the action of the anti-slip soft strip 25, the strap will not slip at the fixation point of the hospital bed. The strap 22 is fixed by Velcro and the first serrated plate 29, which has a good fixing effect, avoids loosening, and fits the hospital bed better.

[0033] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
