Description

Technical Field

[0001] This utility model relates to the field of medical protective equipment technology, specifically to a fall prevention device for the elderly. Background Technology

[0002] Traditional Chinese medicine (TCM) nursing is nursing work guided by the basic theories of TCM. Since ancient times, TCM treatment has mainly been carried out by individual practitioners, so doctors and nurses are often inseparable, and there are no dedicated nurses. For elderly people who have difficulty walking and receiving acupuncture treatment, fall prevention while walking is very important.

[0003] Currently, elderly people with mobility issues need to use walking aids to prevent falls while walking, or they need medical staff to accompany them. The former requires the elderly to exert their own strength, and when the elderly are weak, the preventive effect is minimal. The latter requires investment in personnel, and the prevention process tests the responsiveness of medical staff, making it impractical. Utility Model Content

[0004] The purpose of this invention is to provide a fall prevention device for the elderly in order to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The upper end of each fixing plate is rotatably connected to a main sleeve via a hinge. Several telescopic tubes are sleeved inside each main sleeve. The telescopic tubes are arranged in descending order of size, and the lower end of the bottom telescopic tube is designed to be sealed. Both ends of the sponge waist belt are provided with adhesive fixing structures for interlocking and fixing.

[0007] Each of the main sleeves has a detachable upper end connected to a detonation inflation structure for rapid inflation into its interior, and an angled airbag communicating with the interior of the main sleeve is connected between the main sleeve and the fixed plate.

[0008] Preferably, the lower inner wall and upper outer wall of each telescopic tube are fixedly connected with mutually abutting sealing rings, and the lower inner wall of the main sleeve is also provided with a sealing ring adapted to the upper telescopic tube. Each of the two sides of the telescopic tube is provided with a spring plate groove at the lower end, and a W-shaped spring plate is fixedly connected in each of the two spring plate grooves. The middle corner of the W-shaped spring plate abuts and adapts to the upper end of each telescopic tube located on the lower side.

[0009] Preferably, both ends of the sponge waistband are provided with interlocking and matching wavy grooves. The adhesive fixing structure includes a fixing strap fixedly connected to one end of the sponge waistband, and the other end of the sponge waistband is fixedly connected to a through loop that fits with the fixing strap. After the fixing strap passes through the through loop, it is pulled back and fixed. The end of the fixing strap is fixedly connected to a Velcro hook surface, and the surface of the fixing strap is fixedly connected to a Velcro loop surface that is adhesively adapted to the Velcro hook surface.

[0010] Preferably, the detonation and inflation structure includes a storage box, the lower end of which has a threaded groove that is threaded to the upper end of the main sleeve. A thin film is fixedly connected to the lower side of the inside of the storage box, and a gas generating agent is stacked on the upper end of the thin film. An igniter for contacting the gas generating agent is fixedly installed on the inner top of the storage box.

[0011] Preferably, the side wall of the main sleeve is provided with a through hole that communicates with the interior of the included-angle airbag.

[0012] Preferably, a magnet is fixedly connected to the inner top of the main sleeve, each of the telescopic tubes is made of plastic, and an iron ring that is magnetically compatible with the magnet is fixedly connected to the upper end.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1-5 As shown, this utility model provides a fall prevention device for the elderly, including a sponge waist belt 1. Several fixing plates 2 are fixedly connected to the outer surface of the sponge waist belt 1. The upper end of each fixing plate 2 is rotatably connected to a main sleeve 5 via a hinge. Several telescopic tubes 6 are sleeved inside each main sleeve 5. The telescopic tubes 6 are arranged in descending order of size, and the lower end of the bottom telescopic tube 6 is designed to be sealed. Both ends of the sponge waist belt 1 are provided with adhesive fixing structures 3 for interlocking and fixing each other.

[0026] Each main sleeve 5 has a detachable upper end connected to a detonation inflation structure 4 for rapid inflation into it, and an angled airbag 10 communicating with the inside of the main sleeve 5 is connected between the main sleeve 5 and the fixing plate 2. It is worth mentioning that the number of main sleeves 5 shown in the figure is four, but in actual use, it can be set to six, eight or even ten, etc., depending on the actual situation to ensure the support effect.

[0027] Reference Figure 3 As shown in Figure 5, the lower inner wall and upper outer wall of each telescopic tube 6 are fixedly connected with mutually abutting sealing rings 16 (the lower inner wall of the lowest telescopic tube 6 does not have a sealing ring 16), and the lower inner wall of the main sleeve 5 is also provided with a sealing ring 16 that matches the upper telescopic tube 6. Each telescopic tube 6 has a spring groove 14 at the lower end of both side walls (the lower end of the lowest telescopic tube 6 does not have a spring groove 14, while the lower end of the main sleeve 5 has a spring groove 14 that matches the uppermost telescopic tube 6). W-shaped springs 15 are fixedly connected to both spring grooves 14. The middle bend of the spring piece 15 abuts against the upper end of each telescopic tube 6 located on the lower side. The sealing ring 16 can make every two telescopic tubes 6 fit tightly together to prevent gas leakage. Since the lower end of the lowest telescopic tube 6 is sealed, several telescopic tubes 6 can be effectively driven to unfold through gas expansion. After unfolding to the bottom, the W-shaped spring piece 15 will be unrestricted, and the middle bend of the W-shaped spring piece 15 will pop out inward to abut against the upper end of the telescopic tube 6 to prevent the telescopic tube 6 from moving upward. At the same time, the two sealing rings 16 abut against each other to prevent the telescopic tube 6 from moving downward, thus fixing the telescopic tube 6 after unfolding.

[0028] Reference Figure 2 As shown, both ends of the sponge waist belt 1 are provided with interlocking and matching wavy grooves 7. The adhesive fixing structure 3 includes a fixing strap 3b fixedly connected to one end of the sponge waist belt 1, and a through loop 3a fitted with the fixing strap 3b fixedly connected to the other end of the sponge waist belt 1. The fixing strap 3b passes through the through loop 3a and is pulled back to fix it. The end of the fixing strap 3b is fixedly connected with a Velcro hook surface 3c, and the surface of the fixing strap 3b is fixedly connected with a Velcro loop surface 3d that is adapted to the Velcro hook surface 3c for adhesion. Several wavy grooves 7 can fix elderly people with different waist sizes and effectively prevent separation at the joint. When two wavy grooves 7 are aligned with each other, the fixing strap 3b is inserted into the through loop 3a and pulled back. At this time, the sponge waist belt 1 is tightly attached to the waist. Then the Velcro hook surface 3c and the Velcro loop surface 3d are adhered to each other to complete the fixation.

[0029] Reference Figure 4As shown, the detonation and inflation structure 4 includes a storage box 4a. The lower end of the storage box 4a has a threaded groove 4b that is threaded to the upper end of the main sleeve 5. A membrane 4c is fixedly connected to the lower side of the interior of the storage box 4a. A gas generating agent 4d is stacked on the upper end of the membrane 4c. An igniter 4e is fixedly installed on the inner top of the storage box 4a to contact the gas generating agent 4d. The igniter 4e is controlled to ignite the gas generating agent 4d, which instantly breaks through the membrane 4c and enters the main sleeve 5 and several telescopic tubes 6. It forcefully pushes the main sleeve 5 and several telescopic tubes 6 to unfold, thus preventing falls for the elderly.

[0030] Furthermore, the main sleeve 5 has a through hole 11 on its side wall that communicates with the inside of the angled airbag 10. The generated gas can be injected into the inside of the angled airbag 10 through the through hole 11, causing the angled airbag 10 to inflate and support the main sleeve 5 to expand outward at a certain angle, so that the expanded telescopic tube 6 can play a better supporting role.

[0031] Specifically, a magnet 12 is fixedly connected to the inner top of the main sleeve 5. Each telescopic tube 6 is made of plastic and has an iron ring 13 fixedly connected to its upper end, which is magnetically compatible with the magnet 12. The plastic telescopic tube 6 can reduce the weight when wearing it. At the same time, the magnet 12 fixes several telescopic tubes 6 in a retracted state through magnetic force (due to the restriction of the W-shaped spring 15, the iron ring 13 at the upper end of each telescopic tube 6 does not contact the magnet 12 at this time. Therefore, the gas generated by detonating the inflation structure 4 can push several telescopic tubes 6 to unfold).

[0032] As an optional implementation, an acceleration sensor 9 is fixedly installed on the inner wall of the sponge waist belt 1, and a controller 8 is fixedly installed on the outer wall of the sponge waist belt 1. The igniter 4e, the acceleration sensor 9, and the controller 8 are all powered by a battery. The output terminal of the acceleration sensor 9 is electrically connected to the input terminal of the controller 8, and the output terminal of the controller 8 is electrically connected to the input terminal of the igniter 4e. When the elderly person's body tilts, the acceleration sensor 9 detects the body tilt and sends an electrical signal to the controller 8. The controller 8 then controls the igniter 4e to detonate the gas generator 4d, causing the generated gas to extend the telescopic tube 6.

[0033] Working principle:

[0034] The sponge waist belt 1 is wrapped around and fixed around the waist. At this time, several main sleeves 5 are evenly distributed around the body. When the elderly person's body tilts, the acceleration sensor 9 detects the tilt and sends an electrical signal to the controller 8. The controller 8 then controls the detonation inflation structure 4 to quickly inflate the main sleeves 5 and several telescopic tubes 6. Since the lower end of the lowest telescopic tube 6 is sealed, under high pressure, several telescopic tubes 6 suddenly extend and expand within 0.5 seconds. At the same time, the angled airbag 10 also suddenly expands, causing the extended telescopic tubes 6 to expand outward at a certain angle to support the elderly person's body around the body and prevent falls.

[0035] First, the acceleration sensor 9 receives the tilting signal. As long as the specified intensity is reached, the sensor will activate and send a signal to the controller 8. 2. After receiving the signal, the controller 8 compares it with its original stored signal. If the deployment conditions are met, it sends a start signal to the detonation and inflation structure 4. 3. After receiving the signal, the detonation and inflation structure 4 ignites the gas generator 4d, producing a large amount of gas. After cooling, the gas enters several telescopic tubes 6, causing the telescopic tubes 6 to deploy rapidly in a very short time.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
