Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a fall prevention garment for children under general anesthesia. Background Art

[0002] After general anesthesia surgery, children often show symptoms such as blurred consciousness, decreased balance ability, and weakened muscle strength, and are prone to falling, causing secondary injuries. At present, clinically, it mainly relies on medical staff to strengthen care and bed rail protection to prevent children from falling, but the above methods have the defects of severely restricting the activities of children and excessively high labor costs.

[0003] In response to this, there are also ways to complete the support during the movement of children by setting up portable brackets, or by children wearing corresponding airbag devices to provide protection when children fall. However, the above methods still have the following defects: due to the weakened muscle strength of children after general anesthesia, such devices can only provide a supporting effect and cannot assist the movement of children themselves. Children still have problems with difficult movement. At the same time, there are still certain safety risks due to the weakened muscle strength of children causing side turning or unstable grasping of the brackets. Therefore, improvement is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a fall prevention garment for children under general anesthesia, which can assist the movement of children while preventing children from falling, so as to improve the activity of children and promote postoperative recovery.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A fall prevention garment for children under general anesthesia, comprising:

[0007] A wearing piece, the wearing piece is in a trouser-like structure for wrapping the lower limbs and waist of a child;

[0008] A protection frame, the protection frame includes an upper and lower installation ring and a connecting arc plate. The installation ring and the connecting arc plate are both arranged around the human body. The notch of the connecting arc plate corresponds to the moving direction of the human body. A connecting rod is provided between the installation ring and the connecting arc plate and is fixedly connected to each other through the connecting rod. An armrest is provided on the connecting rod;

[0009] A traction device, the traction device is located inside the installation ring. The traction device includes a reel and a traction rope. One end of the traction rope is wound around the reel, and the other end is connected to the wearing piece. A spring is provided on the reel. The spring is used to drive the reel to rotate back and provide traction force for the wearing piece through the traction rope;

[0010] A locking mechanism, which is connected to the reel. When the forward rotation speed of the reel exceeds the threshold, the locking mechanism locks the reel to limit the forward rotation of the reel.

Detailed implementation manners

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The same components are denoted by the same reference numerals.

[0026] As Figure 1-8 shown, a general anesthesia children's anti-fall clothing includes: a wearable piece 1, the wearable piece 1 is in a trouser-like structure for wrapping the lower limbs and waist of a child. Specifically, the wearable piece 1 includes a waistband and a crotch cloth. One end of the crotch cloth is fixedly connected to the waistband, and the other end is detachably fixed to the waistband by means of Velcro / buttons. Among them, the waistband is made of elastic material to adapt to the body curves of different children.

[0027] It further includes a protective frame 2. The protective frame 2 includes a mounting ring 3 and a connecting arc plate 4 arranged up and down. Both the mounting ring 3 and the connecting arc plate 4 surround the human body. The notch of the connecting arc plate 4 corresponds to the moving direction of the human body. And, a universal wheel is installed at the bottom of the connecting arc plate 4. The number of the universal wheels is multiple and arranged circumferentially to avoid the interference of the ring structure on the human body movement. A connecting rod 5 is provided between the mounting ring 3 and the connecting arc plate 4 and they are fixedly connected to each other through the connecting rod 5. Specifically, the number of the connecting rods 5 is 2 and they are symmetrically arranged. Specifically, when the front of the child corresponds to the notch of the connecting arc plate 4, the two connecting rods 5 are respectively arranged on both sides of the child to ensure the overall safety. A handrail 6 is provided on the connecting rod 5. During use, the child can balance the body further through the handrail 6 to improve the moving stability. At the same time, the setting of the handrail 6 can drive the protective frame 2 to move along, so as to avoid the interference of the protective frame 2 on the child's movement.

[0028] It further includes a traction device 7. The traction device 7 is located inside the mounting ring 3. The traction device 7 includes a reel 8 and a traction rope 9. One end of the traction rope 9 is wound around the reel 8, and the other end is connected to the wearable member 1. Specifically, a hook is provided at the end of the traction rope 9 and the wearable member 1 is hooked through the hook. A clockwork spring 10 is provided on the reel 8. The clockwork spring 10 is used to drive the reel 8 to rotate back, and provide traction force for the wearable member 1 through the traction rope 9. During use, the operator connects one end of the traction rope 9 to the wearable member 1, thereby providing a rotational force for the reel 8 through the clockwork spring 10, and completing the upward traction of the human body through the traction rope 9 to reduce the difficulty of the child's movement and improve the child's mobility.

[0029] It further includes a locking mechanism 11. The locking mechanism 11 is connected to the reel 8. When the forward rotation speed of the reel 8 exceeds the threshold value, the locking mechanism 11 locks the reel 8 to limit the forward rotation of the reel 8. Through the setting of the locking mechanism 11, when the child falls, it drives the reel 8 to rotate at a high speed, so as to complete the locking of the reel 8 through the locking mechanism 11, and then complete the locking of the child's body through the traction rope 9 to ensure safety.

[0030] Preferably, the locking mechanism 11 includes a snap ring 12. The snap ring 12 is fixedly connected to the mounting ring 3. The snap ring 12 is arranged corresponding to one end of the reel 8. A plurality of card slots 13 are provided in the circumferential direction of the snap ring 12. A card block 14 is provided at the end of the reel 8 corresponding to the snap ring 12. Specifically, the number of the card blocks 14 is 3 and they are arranged in the circumferential direction along the axis of the reel 8. One end of the card block 14 is provided with a rotating rod 15 and is rotatably connected to the end of the reel 8 through the rotating rod 15. The other end of the card block 14 forms a clamping end and is clamped with the card slot 13 under the drive of centrifugal force. A driving spring 16 is provided at the end of the reel 8. Both ends of the driving spring 16 are respectively connected to the reel 8 and the clamping end and are used to drive the clamping end to move away from the card slot 13.

[0031] During use, when the child falls, it will drive the reel 8 to rotate at a high speed, so that the centrifugal force received by the card block 14 increases, and then drive the clamping end to swing outwards, so that the clamping end is clamped into the card slot 13 to complete the fixation of the reel 8 and the snap ring 12.

[0032] Preferably, the reel 8 includes an outer sleeve 17 and an inner rod 18. A connecting gear 19 is provided at one end of the inner rod. The outer sleeve 17 is sleeved outside the inner rod, and a fixing groove is provided on the inner wall of the outer sleeve 17 corresponding to the connecting gear 19 and is fixedly clamped with the connecting gear 19. An installation surface 20 is provided at the end of the inner rod away from the connecting gear 19. The card block 14 is arranged corresponding to the installation surface 20. The clockwork spring 10 is arranged at the end of the outer sleeve 17 away from the installation surface 20. The inner rod 18 includes a first rod 21 and a second rod 22. An insertion section 23 is formed at the end of the first rod 21. One end of the second rod 22 forms an insertion hole 24 and is inserted with the insertion section 23. A return spring 25 is provided in the insertion hole 24. The return spring 25 is connected to the insertion section 23 and is used to drive the insertion section 23 to return to its original position.

[0033] When in use, when the child falls, the reel 8 rotates at a high speed, so that the clamping block 14 is clamped and fixed with the clamping groove 13. Further, under the impact force, and due to the fixation of the outer sleeve 17 and the first rod 21, the outer sleeve 17 will further rotate relative to the second rod 22 through the first rod 21, so that the traction rope 9 can be moved out of the reel 8 in a small amount, thereby greatly reducing the impact force to reduce the harm caused by the fall impact to the child's body. And, after the impact force disappears, the return spring 25 drives the first rod 21 to rotate back for preparation for the next impact.

[0034] Preferably, a first limiting block 26 is provided on the inner wall of the insertion hole 24, and a second limiting block 27 is provided on the outer wall of the insertion section 23. The first limiting block 26 is used to abut against the second limiting block 27 to limit the rotation range of the insertion section 23 relative to the insertion hole 24, so as to avoid the failure of the anti-fall function caused by excessive rotation of the first rod 21.

[0035] At the same time, in order to ensure the elasticity of the return spring 25, the first limiting block 26 and the second limiting block 27 can be used to abut against each other to control the return spring 25 to maintain a certain elasticity in the initial state, so as to ensure subsequent return and ensure that the first rod 21 can only rotate after the clamping block 14 is clamped.

[0036] Preferably, the connecting rod 5 includes a first fixing rod 28 and a second fixing rod 29 that are telescopically connected to each other. A fixing component 30 is provided between the first fixing rod 28 and the second fixing rod 29. The fixing component 30 is used to keep the first fixing rod 28 and the second fixing rod 29 fixed / movable relative to each other.

[0037] Through the mutual telescoping of the first fixing rod 28 and the second fixing rod 29, the appropriate position of the mounting ring 3 can be adjusted according to the specific use environment and the height of the child, so as to improve the overall adaptability.

[0038] Preferably, an adjustment hole 31 is provided on the second fixing rod 29. One end of the first fixing rod 28 is inserted and telescoped with the adjustment hole 31. Fixing holes 32 are provided on the first fixing rod 28 and the second fixing rod 29 along the length direction. The fixing component 30 includes a first spring 33 and a first telescopic block 34 arranged in the fixing hole 32. The first spring 33 is used to drive the first telescopic block 34 to move outwards. When the first telescopic block 34 passes through the two fixing holes 32, the first fixing rod 28 and the second fixing rod 29 are fixed to each other.

[0039] In the initial state, driven by the first spring 33, one end of the first telescopic block 34 passes through the corresponding fixing holes 32 of the first fixing rod 28 and the second fixing rod 29 respectively. At this time, the first fixing rod 28 and the second fixing rod 29 are relatively fixed. When the length needs to be adjusted, by pressing the first telescopic block 34, the first telescopic block 34 is separated from the fixing hole 32 corresponding to the second fixing rod 29, so that the first fixing rod 28 can move relative to the second fixing rod 29 to complete the adjustment of the length of the connecting rod 5.

[0040] Preferably, one end of the second fixing rod 29 far from the first fixing rod 28 is connected to the connecting arc plate 4. A connecting seat 35 is hinged at the end of the armrest 6. An installation hole 36 is provided on the connecting seat 35 and the second fixing rod 29 is sleeved thereon. A torsion spring is provided at the hinge of the armrest 6 and the connecting seat 35, and the torsion spring is used to drive the armrest 6 to swing outwards.

[0041] Through the hinge of the armrest 6 and the setting of the torsion spring, when a child falls, the torsion spring can drive the armrest 6 to automatically return to reduce the possible harm that the armrest 6 may cause to the child during the fall.

[0042] Preferably, a plurality of positioning holes 37 are provided along the length direction of the second fixing rod 29. A second telescopic block 38 and a second spring 39 are provided in the connecting seat 35. The second spring 39 is wound in the second telescopic block 38 and is used to drive the second telescopic block 38 to move towards the positioning hole 37. When the second telescopic block 38 is connected to the positioning hole 37, the connecting seat 35 is fixed relative to the second fixing rod 29.

[0043] The height of the connecting seat 35 is adjusted by the expansion and contraction of the second telescopic block 38 to adapt to the use of children of different heights.

[0044] At the same time, the connecting seat 35 is provided with a through groove corresponding to the fixing hole 32 to ensure the exposed state of the first telescopic block 34 at the fixing hole 32.

[0045] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
