Description

Technical Field

[0001] The present invention relates to the technical field of protective auxiliary equipment, and in particular to an injury prevention device. Background Art

[0002] A fall is a sudden, unexpected fall that can occur at any age, but is more common among older adults. It is significantly more common in older women than in older men, generally due to factors such as reduced mobility, poor muscle strength, impaired balance, and cognitive impairment. Because falls can lead to serious consequences such as psychological trauma, fractures, and soft tissue injuries, impacting the physical and mental health of older adults and increasing the burden on families and society, they have become a highly regarded topic in geriatric clinical medicine.

[0003] Due to osteoporosis and increased bone brittleness, elderly people are more susceptible to fractures when falling. This risk increases dramatically with age, leading to serious consequences. Therefore, the development of easy-to-wear clothing that protects against falls holds significant market potential and is beneficial to the physical and mental health of the elderly. Currently, common fall-protection clothing on the market typically utilizes small gas cylinders to inflate the garment's airbags in an emergency.

[0004] At present, in medical activities, sudden changes in patients' conditions often occur, especially when the patient suddenly loses consciousness due to an epileptic seizure. The patient will quickly fall to the ground in an uncertain direction with his jaws clenched, which will cause damage to the patient's body. Therefore, a device is designed that can protect the patient before he falls to the ground during the seizure to prevent limb injuries. At the same time, the neck device is triggered, and after the head is protected, objects are inserted from the patient's molars to prevent the patient from biting the tongue. Video recording can also be performed to facilitate doctors to understand the process of the seizure and assist in disease diagnosis. At the same time, there is an alarm prompt sound when triggered, and the patient can call strangers around for help in time. Voice conversations can also be carried out on the mobile phone to guide others to assist in first aid, etc. Summary of the Invention

[0015] Furthermore, at least one multi-axis motion sensor and an alarm are provided on the inner side of the vest, the fixing ring is in a matching state with the collar of the vest, and a video monitoring system is provided at the upper end of the slide.

[0016] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0017] First, before a person falls to the ground, the device can eject an airbag to wrap his or her head, hands, legs, buttocks and other parts, thereby reducing the impact force between the human body and the ground, thereby alleviating personal injuries. At the same time, it can protect epileptic patients or people who are at risk of biting their tongue after falling. The speed and force of the airbag when it is ejected are very large, so it is completely sufficient to be used as the driving force of the device.

[0018] Secondly, when a person with leg muscle atrophy wears the device, the vest is first put on the required part of the person, and then the upper hand and leg clothes are put on. At this time, the video surveillance system is turned on, and the wearing and wearing of the device is completed. The slide and the fixed ring are in a disassembled state at this time. When a person is walking and has leg weakness, falls after an epileptic seizure, or falls due to uneven road surface or being hit by a vehicle, the multi-axis motion sensor inside the vest will detect that the person is falling, thereby issuing an alarm and quickly transmitting the command to the airbag. At this time, the airbag will be inflated in a very short time, wrapping the head, hands, legs, buttocks and other parts of the person, thereby reducing the impact force between the person and the ground, thereby reducing personal injury.

[0019] Third, after the airbag of the present invention is ejected, the alarm will sound a loud sound to call for help. When the person is walking, the video surveillance system is always in the camera state, and the mobile phone has downloaded an APP matching the video surveillance system. This APP has the functions of video storage, real-time viewing, and playback. The video surveillance system also has a position positioning function. First, if a person falls, the cause of the fall can be viewed on the APP. Second, after an epileptic patient falls during an attack, the fall video can be provided to medical staff, which is convenient for medical staff to further diagnose the epileptic attack. Third, the location of the person can be found in time through the mobile phone, and family members can quickly arrive at the scene.

[0020] Fourthly, the ejection groove provided in this device can facilitate the ejection of the airbag, and the setting of the fixing ring can support the device and open the vest collar, so that there is a certain space for the airbag to be ejected, and the cooperation and limitation of the slide can avoid injury to the head of the person hit by the airbag when it is ejected.

[0021] Fifth, during the movement of the connecting block of this device, after the connecting block disengages from the first sliding groove on the slide, the connecting groove on the connecting block will be stuck on the pushing block and drive it to move. The electric push rod is powered by a lithium battery. Since the head of a person is generally in the shape of a symmetrical combination of the two slides in this device, and a part of the lower end of the slide is vertically set, this device is matched with the person. This device is equipped with a series of connecting devices, slides, and pushing devices to cooperate with the movement of the person's head shape, so that this device moves around the outside of the person's head, wraps the person's head with the airbag limited, and moves the pushing device to the required position for operation.

[0022] Sixth, this device can quickly send instructions to the airbag when a person falls by setting a multi-axis motion sensor. At this time, the airbag will be inflated in a very short time, wrapping the head, hands, legs, buttocks and other parts of the human body, thereby reducing the impact force between the human body and the ground, thereby reducing personal injuries. After the airbag is ejected, the alarm will make a loud sound to call for help.

[0023] Seventh, this device can change the movement distance of the two push-in slide rails by turning the adjustment knob, and plays an adjustment role in the calibration process of the push-in block and the person's mouth. The limit device set can prevent the drive device from rotating due to inertia or other reasons after the rack is disengaged from the gear, thereby preventing the subsequent movement of the retracting device from affecting the subsequent movement of the retracting device.

By making the pushing block 34 and the chin cover 14 both made of silicone, it can protect the personnel, and by making the pushing block 34 into a triangular shape, it can be easily inserted into the cavity of the person.

[0050] Preferably, at least one multi-axis motion sensor and an alarm are provided on the inside of the vest 1, the fixing ring 11 is in a matching state with the collar of the vest 1, and a video monitoring system 4 is provided at the upper end of the slide 12. By setting up a multi-axis motion sensor, when a person falls, instructions can be quickly issued to the airbag. At this time, the airbag will be inflated in a very short time, wrapping the head, hands, legs, buttocks and other parts of the human body, thereby reducing the impact force between the human body and the ground, thereby reducing personal injuries. After the airbag is ejected, the alarm will make a loud sound to call for help.

[0051] Working principle: When a person with leg muscle atrophy wears the device, first put the vest 1 on the required part of the person, then put on the upper hand and leg clothes, then turn on the video monitoring system 4, and the device is put on and put on. The slide 12 and the fixing ring 11 are now in the detached state;

[0052] When a person falls due to leg weakness, epileptic seizure, or on uneven roads or being hit by a vehicle while walking, the multi-axis motion sensor inside the vest 1 will detect the person's fall, sound an alarm, and quickly transmit the command to the airbag. The airbag will then be inflated in a very short time, wrapping the person's head, hands, legs, buttocks, etc., thereby reducing the impact force between the person and the ground and alleviating personal injuries.

[0053] After the airbag is ejected, the alarm will sound loudly to call for help. When the person is walking, the video surveillance system 4 is always in the camera state, and the mobile phone has downloaded an APP that matches the video surveillance system 4. This APP has the functions of video storage, real-time viewing, and playback. The video surveillance system 4 also has a location positioning function. First, if a person falls, the cause of the fall can be viewed on the APP. Second, if an epileptic patient falls during a seizure, the fall video can be provided to medical staff, which facilitates medical staff to further diagnose the epileptic seizure. Third, the person's location can be found in time through the mobile phone, and family members can quickly arrive at the scene.

[0054] When an epileptic patient or a person who is at risk of biting the tongue after falling is walking, the slide 12 is installed on the fixing ring 11. At this time, the vest 1, upper hand clothing and leg clothing can be put on, and then the chin cover 14 is fitted to the person's chin. By stretching the two connecting ropes 13, the other ends are passed from top to bottom around the retraction shaft 52 and fixed on the retraction shaft 52, so that the chin cover 14 can fit more tightly to the person's chin, and the two connecting ropes 13 are in a relatively taut state at this time. Both connecting ropes 13 have a certain toughness and strength, so that different people can wear the chin cover 14. The chin cover 14 is made of silicone material to avoid diaphragm of the person, so that the person can wear it in a more comfortable state. After the person falls, the airbag will pass through the ejection slot on the fixing ring 11 in the vest 1. After 111 pops out, it wraps the head, chest, buttocks and other parts, and ejects the hands and legs from the inside of the hand and leg clothes. During the ejection groove 111 on the fixed ring 11, since the airbag is in a connected state with the connecting hook 22, and the connecting block 21 is in a sliding fit with the first sliding groove 121, the impact force of the airbag ejection will drive the connecting block 21 to slide in the first sliding groove 121 in the shape of the first sliding groove 121. During the movement of the connecting block 21, the connecting block 21 will disengage from the first sliding groove 121 on the slide 12, so that the connecting groove 211 on the connecting block 21 is just stuck on the pushing and extending block 34, and drives it to move. At this time, the support point of the sliding is changed from the connecting block 21 to the two pushing and extending slide rails 31, and it slides in the corresponding second sliding groove 122, and moves to Figure 11 In the state shown, after the chin cover 14 is worn, the pushing device 3 can be manually stretched and slid to calibrate the position of the pushing block 34 with the person's mouth, and the adjustment device 8 is rotated to limit the sliding distance of the two subsequent pushing slide rails 31, so as to correspond the pushing block 34 with the person's mouth, so that after calibration, the pushing block 34 can be located at the previously calibrated position through the impact force of the airbag ejection, so that the pushing block 34 can be accurately pushed into the mouth through the movement of the electric push rod 33. The block 34 is inserted into the mouth of the person to prevent him from biting his tongue and causing injury. During the sliding process of the two push-in slide rails 31, the rack 311 on one of the two push-in slide rails 31 will be driven to move. After the movement, the rack 311 will drive the gear 66 to rotate, and the rotation of the gear 66 will drive the drive shaft 62 to rotate on the drive block 61. The rotation of the drive shaft 62 will synchronously drive the driven wheel 64 to rotate. The rotation of the driven wheel 64 will drive the driving wheel 63 to rotate through the sleeve transmission of the belt 65, and the rotation of the driving wheel 63 will drive the retracting shaft 52 to rotate. According to the following example, Figure 9The winding manner of the two connecting ropes 13 shown will stretch and reel the two connecting ropes 13 during the rotation of the retraction shaft 52, and the stretching and reeling movement of the two connecting ropes 13 will drive the chin sleeve 14 mounted on the person's chin to stretch, and the person's chin will drive the person's chin to move through the stretching force of the chin sleeve 14, and make the person's mouth open, and at the same time create a larger gap between the lower teeth and the upper teeth. After this process is completed, the pushing device 3 also completes the sliding, so that the pushing block 34 corresponds to the mouth part, so as to facilitate the better insertion of the pushing block 34 into the person's mouth, preventing the person from biting the tongue and causing injury, avoiding muscle tension when the person falls, and epileptic patients with teeth being clenched during an attack, making it impossible to insert the pushing block 34 into the person's mouth, thereby playing a protective role. Since the airbag transmits signals through a multi-axis motion sensor, the airbag will complete a series of movements in about 0.2 seconds, so that the above-mentioned movement process is completed before the person falls to the ground, achieving physical protection for the person, and also preventing epileptic patients from biting their tongues.

[0055] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
