[0002] The guardrails of hospital beds are fixed on both sides of the bed and can be folded down. However, the gaps between the head and foot of the bed and the guardrails are too large, which poses a certain risk of falling or falling out of bed for patients with a history of mental illness, confused consciousness, and elderly patients with thin constitutions. In particular, at night, patients often climb out of the gaps between the head and foot of the bed and the guardrails, which can easily cause falls and fall out of bed. In mild cases, they may suffer skin abrasions and lacerations, while in severe cases, they may suffer fractures or internal organ damage. This not only increases the patient's hospitalization expenses, but also seriously affects the quality of nursing work.

A second clamping block 12 is installed on the back of each of the sleeve boxes 8, and the back refers to the side away from the box opening. A second clamping hole is provided on the second clamping block 12, and the second clamping hole faces the side of the hospital bed 1. The second clamping hole is clamped on the headboard or the footboard of the hospital bed 1, and a second clamping hole 11 is provided on the second clamping block 12. The axis of the second clamping hole 11 is perpendicular to the opening direction of the second clamping hole, and the second clamping hole 11 is connected to the second clamping hole, and a fixing stud 15 is connected in the second clamping hole 11, and the end of the fixing stud 15 abuts on the headboard or the footboard of the bed 1 in the second clamping hole.
[0026] Furthermore, the shielding structure mainly includes a curtain 4, a rolling rod 19 is installed in the sleeve box 8, the length direction of the rolling rod 19 is parallel to the length direction of the sleeve box 8, the first end of the rolling rod 19 is rotatably connected to the inner side surface of the sleeve box 8, the curtain 4 is wound on the rolling rod 19, the free end of the curtain 4 is connected to the side surface of the fixed plate 16, the second end of the rolling rod 19 passes through the sleeve box 8, and the second end of the rolling rod 19 is equipped with a rotating wheel 2, a gear 21 is installed on the rolling rod 19, the axis of the gear 21 coincides with the axis of the rolling rod 19, the gear 21 is installed on the inner side surface of the sleeve box 8 near the second end of the rolling rod 19, and a socket is opened on the side of the sleeve box 8, a plug rod 24 is plugged into the socket, and the plug rod 24 is movably engaged with the teeth of the gear 21.
[0027] During the specific use of the present invention, the fixing plate 16 is installed on the outside or inside of the guardrail through the first latching hole on the first clamping block 13 of the fixing plate 16. When the fixing plate 16 is installed on the outside of the guardrail, it will not occupy the position of the bed 1, and therefore will not reduce the patient's activity space. Then, the limiting rod 18 is inserted into the first latching hole on the first clamping block 13, and the long rod 10 of the guardrail is restricted in the first latching hole by the limiting rod 18, so that the long rod 10 will not be separated from the first latching hole, thereby allowing the fixing plate 16 to be fixed to the long rod 10 of the guardrail through the first clamping block 13. Because there are two first latching holes, the limiting rods 18 on the two first latching holes are respectively located on one of the short rods of the guardrail, so that the first clamping block 13 cannot slide freely on the long rod 10, and thus the fixing plate 16 cannot slide on the long rod 10, so that the position of the fixing plate 16 is fixed. Furthermore, a stopper 14 is provided at one end of the limiting rod 18. A limit nut 17 is threadedly connected to the limiting rod 18. The stopper 14 and the limit nut 17 respectively abut against the back of the first clamping block 13 and the fixing plate 16. The limiting rod 18 is fixed to the first clamping block 13 and the fixing plate 16 via the limit nut 17 and the stopper 14, so that the limiting rod 18 does not disengage from the first clamping hole, thereby ensuring that the fixing plate 16 is stably fixed to the guardrail. A sleeve 8 is sleeved on both sides of the fixing plate 16. The two sleeves 8 are respectively clamped to the headboard or footboard of the bed 1 through the second clamping hole of the second clamping block 12. Then, the sleeves 8 are threadedly connected to the second clamping hole 11 via a fixing stud 15, so that the fixing stud 15 clamps the second clamping block 12 to the headboard or footboard of the bed 1, thereby fixing the second clamping block 12 to the headboard or footboard of the bed 1. Both sets 8 are equipped with a stowable shielding structure. When deployed, the shielding structure blocks the gaps at the head and foot of the bed 1 and the gaps in the guardrails to prevent the patient from falling out of bed 1. When the present invention is not needed, the shielding structure can be stored in the sets 8, and then the sets 8 can be connected to both sides of the fixing plate 16, thereby reducing the space occupied by the device.
[0028] Because the lengths of hospital beds 1 vary slightly, the lengths required for shielding also vary, and therefore, the length of the shielding structure needs to be adjustable. Furthermore, the shielding structure is shielded by a curtain 4, which is wound on a rolling rod 19, and the length of the curtain 4 when unfolded can be adjusted according to the length of the bed 1. When using this device, pull out the insertion rod 24 on the sleeve box 8, so that the insertion rod 24 is disengaged from the gear 21, and the insertion rod 24 no longer restricts the rotation of the winding rod 19, so that the winding rod 19 can rotate, and the curtain 4 can be opened from the winding rod 19, and then the fixing plate 16 is fixed to the guardrail, and the sleeve box 8 on both sides of the fixing plate 16 is fixed to the headboard and the footboard of the bed 1 respectively, and then the winding rod 19 is rotated by the rotating wheel 2 to tighten the curtain 4, so that the curtain 4 is taut and blocks both sides of the bed 1, and the insertion rod 24 on the protective sleeve box 8 is inserted into the gear 21, and the insertion rod 24 is inserted into the tooth pressure of the gear 21, limiting the rotation of the gear 21, thereby limiting the rotation of the winding rod 19, and the curtain 4 on the winding rod 19 will not be unwound or reeled, and will remain taut to block both sides of the bed 1. When the patient exerts force on the bed 1 in the direction of the curtain 4, the curtain 4 will not be reeled or unreeled due to the limiting effect of the insertion rod 24, and will always block the two sides of the bed 1, thereby preventing the patient from falling or falling off the bed 1. Moreover, because the curtain 4 is made of soft material, when the patient accidentally hits the curtain 4, it will not hurt, and it has a certain cushioning effect. Furthermore, the curtain 4 is made of breathable mesh, which is convenient for ventilation. Furthermore, the first end of the insertion rod 24 is installed with a handheld block 3, and the other end of the insertion rod 24 is installed with an insertion block 23. The sizes of the handheld block 3 and the insertion block 23 are both larger than the size of the socket. The end of the insertion block 23 is narrow on the outside and wide on the inside, and the inside refers to the side close to the socket. The insertion block 23 is inserted into the teeth of the gear 21. When the insertion rod 24 is pulled outward to the outermost end, the insertion block 23 abuts against the inner wall of the sleeve 8, and the insertion block 23 is not engaged with the gear 21. The rod 24 is inserted or pulled out by the hand-held block 3. The end of the block 23 is narrow on the outside and wide on the inside, making it easy to insert into the teeth of the gear 21. The size of the hand-held block 3 and the block 23 is larger than the size of the socket, so that the rod 24 will not be detached from the socket and will not be lost, which is convenient for subsequent use. Furthermore, the socket is a non-circular hole, and the rod 24 is slidably connected to the socket. The socket is a non-circular hole, so that the rod 24 will not rotate with the socket, so that the block 23 on the rod 24 can be well inserted into the teeth of the gear 21. In order to neatly roll up the curtain 4 on the winding rod 19, two baffles 9 are further provided on the winding rod 19. The curtain 4 is wound on the winding rod 19 between the two baffles 9. The two baffles 9 act as a limiter, so that the curtain 4 can be neatly rolled up between the two baffles 9.
[0029] When the device is not in use, the limiting nut 17 on the limiting rod 18 on the first clamping block 13 is removed to disengage the limiting rod 18 from the first clamping hole, thereby disengaging the fixing plate 16 from the guardrail. After the fixing plate 16 is disengaged from the guardrail, the limiting rod 18 is reinserted into the first clamping hole and secured with the limiting nut 17. This prevents the limiting rod 18 and limiting nut 17 from being lost and eliminates the need to store them separately, making them convenient for next use. Then, first remove the fixing stud 15 in the second locking hole 11 of one of the second locking blocks 12, so that the sleeve 8 corresponding to the second locking block 12 is separated from the headboard or footboard of the bed 1, and pull out the insertion rod 24 on the sleeve 8 through the hand-held block 3 so that the insertion block 23 on the insertion rod 24 is no longer engaged with the gear 21. Then rotate the wheel 2 at the end of the winding rod 19 so that the winding rod 19 rewinds the curtain 4 and stores the curtain 4 in the sleeve 8. Then, reinsert the insertion rod 24 into the teeth of the gear 21 to prevent the rotation of the winding rod 19 from causing the curtain 4 to unwind and affect storage. Finally, the sleeve 8 is connected to the side of the corresponding fixed plate 16. Similarly, the shielding structure on the other side is stored in the sleeve 8, and then the sleeve 8 is also connected to the side of the corresponding fixed plate 16. The device can be stored to reduce the occupied space.
[0030] The cover 8 is attached to the side of the headboard or footboard of the bed 1 via a second clamping block 12. To reduce the space occupied by the device, the second clamping block 12 is designed to be removable. Furthermore, a protrusion 7 is mounted on the back of the cover 8. The protrusion 7 has a connecting hole 20. The second clamping block 12 has a third clamping hole 22, the axis of which is parallel to the opening direction of the second clamping hole. A connecting rod 6 is connected to the connecting hole 20 and the third clamping hole 22. One end of the connecting rod 6 is provided with a connecting block. A connecting nut 5 is threadedly connected to the connecting rod 6. The connecting block abuts the inner wall of the second clamping block 12, and the connecting nut 5 abuts the protrusion 7. The second clamping block 12 is mounted in the third clamping hole 22 on the protrusion 7 of the cover 8 via the connecting rod 6 and the connecting nut 5, securing the second clamping block 12 to the cover 8. When the device is not in use, the shielding structure is stored in the cover 8, and the two cover 8s are connected to the two sides of the fixing plate 16. At this time, when the second clamping block 12 is no longer needed to be fixed to the headboard or the footboard of the bed 1, unscrew the connecting nut 5, remove the connecting rod 6 and the second clamping block 12, and clamp the two removed second clamping blocks 12 on the back of the two sets of boxes 8 respectively, use the fixing stud 15 to connect it with the second clamping hole 11 from one side of the second clamping block 12, and use the connecting rod 6 to insert it from the second clamping hole 11 on the other side of the second clamping block 12. The end of the fixing stud 15 abuts on the plate surface of the fixing plate 16, and one end of the connecting rod 6 abuts on the other plate surface of the fixing plate 16. The connecting nut 5 on the connecting rod 6 abuts on the second clamping block 12. By fixing the stud 15, the connecting rod 6 and the second clamping block 12, the second fixed block, the set of boxes 8, and the fixing plate 16 are fixed together, which is not easy to lose and is convenient for storage.
