[0027] To better understand the purpose, structure, and function of this utility model, a head restraint strap of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1-5As shown, this utility model discloses a head restraint strap, including a pad 1. Two connecting straps 2 are provided at both ends of the pad 1, arranged in a triangular pattern with the pad 1. This triangular arrangement makes the pad 1 more securely and reliably fixed to the bed frame. Each of the two connecting straps 2 is connected to a fixing strap 4 via a connector 3. The connector 3 includes a base plate 14 and a top plate 17. Three orderly arranged first studs 15 are provided on the upper surface of the base plate 14. Three second through holes 18, corresponding one-to-one with the first studs 15, are provided on the surface of the top plate 17. The end surfaces of the connecting straps 2 and the fixing strap 4 are each provided with first through holes 16, corresponding to the first studs 15. The top of each first stud 15 passes through the first through hole 16 and the second through hole 18 and is threaded with a knob. Through the connector 3, the fixing strap 4 can be securely fixed. The connection between the strap 4 and the connecting strap 2 is detached and installed to facilitate the replacement of the fixing strap 4. Specifically, the knob on the first stud 15 is removed, allowing the top plate 17 to be removed from the bottom plate 14. This allows the connecting strap 2 and the fixing strap 4 to be removed from the first stud 15. During installation, the first through holes 16 on both the connecting strap 2 and the fixing strap 4 are inserted into the corresponding first studs 15. The top plate 17 is then replaced, allowing the second through holes 18 to be inserted into the corresponding first studs 15. Finally, the knobs are screwed onto the first studs 15. A socket 20 is provided in the middle of the upper surface of the bottom plate 14, and insertion blocks 21 corresponding to the socket 20 are provided in the middle of the bottom of the top plate 17. The insertion blocks 21 and the socket 20 ensure a tighter connection between the bottom plate 14 and the top plate 17.

[0029] One of the fixing straps 4 has multiple equally spaced third through holes 19 in the middle of its surface along its length. The other fixing strap 4 has a second stud 22 at its end bottom, corresponding to the third through holes 19. The bottom of the second stud 22 extends to the bottom of the third through hole 19 and is threaded with a knob. The fixing straps 4 are fixedly connected to the bed frame by the third through holes 19 and the second stud 22. The specific operation method is to wrap the two fixing straps 4 around the bottom of the bed frame, tighten the fixing straps 4 so that the second stud 22 is inserted into the corresponding third through hole 19, and then tighten the knob. This makes the fixing straps more stable and reliable and prevents them from moving during use.

[0030] A headband 5 is provided on the pad 1. A third female hook and loop fastener 25 is provided on the outer surface of one end of the headband 5, and a third female hook and loop fastener 26 is provided on the inner surface of the other end. An adjustment strap 23 is provided below the third female hook and loop fastener 25 at one end of the headband 5. Multiple second loops 13 are distributed at equal intervals on the surface of the adjustment strap 23. A reinforcing strap 6 is provided at the other end of the headband 5, corresponding to the adjustment strap 23. A first female hook and loop fastener 7 is provided above the back surface of the reinforcing strap 6, and a first female hook and loop fastener 8 is provided below the first female hook and loop fastener 7 on the back surface of the reinforcing strap 6. With the reinforcement strap 6, when the headband 5 is fixed to the patient's head, the end of the reinforcement strap 6 can be passed through the corresponding second loop 13 and tightened according to the size of the patient's head. This allows the second female hook and loop fastener 10 on the reinforcement strap 6 to be attached to the second female hook and loop fastener 11, achieving double fixation of the patient's head, with better restraint effect, and effectively preventing the headband 5 from loosening.

[0031] One end of the headband 5 has a first loop 12 at its bottom, and the other end has an auxiliary strap 9 corresponding to the first loop 12 at its bottom. The back surface of the end of the auxiliary strap 9 has a second sub-hook and loop fastener 10, and the back surface of the auxiliary strap 9, below the second sub-hook and loop fastener 10, has a second female hook and loop fastener 11. Through the cooperation between the auxiliary strap 9 and the first loop 12, the auxiliary strap 9 can pass through the patient's face and chin through the first loop 12. When the auxiliary strap 9 is tightened, the first sub-hook and loop fastener 7 on the auxiliary strap 9 are attached to the first female hook and loop fastener 8, which further improves the restraint effect, prevents the patient's body from slipping, and achieves a stable and reliable position.

[0032] The working principle of this head restraint strap is as follows: First, the pad 1 is fixedly connected to the bed frame via two fixing straps 4, allowing the patient's head to rest on the pad 1. Pulling both ends of the head strap 5 and tightening it causes the third sub-hook and hook fastener 26 to adhere and securely fasten with the third female hook and hook fastener 25. Then, pulling the reinforcing strap 6 allows its end to pass through the corresponding second loop 13, and tightening it causes the second sub-hook and hook fastener 10 on the reinforcing strap 6 to adhere to the second female hook and hook fastener 11, achieving double fixation of the patient's head. Finally, the auxiliary strap 9 passes through the patient's face and chin, through the first loop 12, and tightening the auxiliary strap 9 causes the first sub-hook and hook fastener 7 on the auxiliary strap 9 to adhere to the first female hook and hook fastener 8, further improving the restraint effect and preventing the patient's body from slipping, achieving a stable and reliable position.
