Description

Technical Field

[0001] The invention relates to the technical field of anti-collision pads, and in particular to an anti-collision hip protection anti-collision pad. Background Art

[0002] The hip joint is the main support for the human body to walk upright and move. Once it is fractured, it will seriously affect walking and life. With age, osteoporosis becomes more severe year by year, muscles atrophy, and bones become more brittle. Accidental falls or even minor trauma can cause fractures. Hip fractures account for about 7% of all fractures in adults. Among the elderly over 65 years old, hip fractures account for 23.79% of all fractures. After the elderly suffer a hip fracture, they often develop serious complications such as heart disease, bedsores, urinary tract infections, aspiration pneumonia, lower extremity venous thrombosis, and even life-threatening.

[0003] The incidence and mortality rates of hip fractures are high. The mortality rate of hip fracture in the elderly is as high as 8.4%-36% one year after a hip fracture. It is called "the last fracture in life."

[0004] With the progress of population aging, my country has entered an aging society. The incidence of fractures among the elderly has increased year by year, and the number of people has also increased year by year. Therefore, in recent years, society has attached great importance to hip fractures in the elderly. The means and methods for the treatment of hip fractures in the elderly are also constantly improving. Usually, surgical treatment must be used after a fracture, which causes greater trauma to the elderly, and the rate of non-union of fractures is also higher than that of general fractures. Therefore, in order to reduce the risk of hip fractures caused by falls in the elderly, hip protective gear is often used to protect the hip. However, the existing hip protection devices are mostly braces, which play a supporting and fixing role, and have poor shock absorption and anti-collision effects. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an anti-collision hip protection anti-collision pad, which has good shock absorption and anti-collision effects, is easy to use, and can significantly reduce the degree of damage to hip fractures and reduce the risk of hip fractures in falls or other traumatic events to the hip.

[0006] The technical solution adopted by the present invention is:

[0007] The invention discloses an anti-collision hip protection anti-collision pad, comprising two symmetrical pad bodies, the pad bodies are made of a polyurethane + P4U composite material, the pad bodies have an outer shape structure corresponding to the surface of the human hip, the pad bodies comprise a relatively large arc portion and a small arc portion, the large arc portion extends in an arc shape from the upper end of the pad body to the lower end of the pad body, and then bends upward in an arc shape from the lower end of the pad body to extend to the lower end of the small arc portion, when the pad body is worn on the left hip and the right hip of the human body, the small arc portion is located in front of the large arc portion, the arc-shaped protrusions of the large arc portion and the small arc portion are both oriented toward the rear of the human body, a plurality of spacing grooves are provided on the front and back sides of the pad body, the plurality of coplanar spacing grooves extend divergently from the small arc portion to the large arc portion, the spacing grooves on the front side correspond to the spacing grooves on the back side, and a plurality of air holes are provided in the spacing grooves.

[0008] The pad body is made of polyurethane + P4U composite material. The polyurethane + P4U composite material remains relaxed, soft and elastic under normal circumstances. Once it is subjected to severe collision or impact, the molecules immediately lock with each other, quickly tighten and harden to absorb the external force, forming a protective layer. When the external force disappears, the material will return to its original relaxed soft elastic state. Therefore, the pad body made of this material can have good softness under normal conditions and does not affect various postures such as walking, walking, sitting and lying. After being subjected to force during a fall, it has a certain strength and forms a protective layer to dissipate and absorb impact force, thereby reducing the damage to the hip caused by a fall or other impact force. Wearing the pad body of this design on both sides of the hip can play a good protective role, has good shock absorption and anti-collision effects, is easy to use, and can significantly reduce the degree of damage to the hip fracture and reduce the risk of hip fracture in falls or other traumatic events to the hip.

[0009] The design of the spacing grooves on the pad body ensures that the pad body can adjust and deform with the human body's movements, so that it can adapt to various postures such as walking, sitting, and lying, ensuring the freedom and smoothness of daily movements; the design of multiple ventilation holes achieves a breathable effect and avoids stuffiness. The shape of the pad body fits perfectly with the hip bones, which can increase the force-bearing area when falling.

[0010] Furthermore, the pad body includes a main body and an edge portion, wherein the edge portion is arranged around the main body, and the thickness of the edge portion is less than the thickness of the main body, thereby ensuring the protective effect while making the pad body thinner and lighter, so that the body can maintain better flexibility during movement.

[0011] Furthermore, in order to ensure better freedom of movement and smoothness, seven spacing grooves are provided on the front side and the back side.

[0012] Furthermore, in order to achieve a better ventilation effect, two ventilation holes are provided in the spacing groove along the length direction of the spacing groove.

[0013] Furthermore, in order to achieve better protection strength, the thickness of the main body is 5-12 mm.

[0014] Furthermore, in order to achieve a better fitting effect, the thickness of the outermost side of the edge portion is 4 mm.

[0015] Furthermore, in order to match the human waist, the upper end of the cushion body includes an upper edge one and an upper edge two, the upper edge one has an arc corresponding to the human waist, one end of the upper edge one is connected to the upper end of the large arc portion, the other end of the upper edge one is connected to one end of the upper edge two and the angle between the two is an obtuse angle, and the other end of the upper edge two is connected to the upper end of the small arc portion.

[0016] Furthermore, in order to facilitate wearing, the pad body is provided with a wearing component for facilitating wearing of the pad body.

[0017] Furthermore, in order to facilitate the installation of the pad body, the wearable component includes shorts, and the shorts are provided with a mounting portion for mounting the pad body.

[0018] Furthermore, in order to facilitate the installation of the pad body, the installation portion is a fixed bag arranged on both sides of the shorts for placing the pad body.

[0019] The beneficial effects of the present invention are as follows: the pad body 1 is made of a polyurethane + P4U composite material, which remains in a relaxed state, soft and elastic under normal conditions. Once subjected to a severe collision or impact, the molecules immediately lock with each other, quickly tighten and harden to absorb the external force, and form a protective layer. When the external force disappears, the material returns to its original relaxed soft elastic state. Therefore, the pad body made of this material can have good softness under normal conditions, and does not affect various postures such as walking, walking, sitting, and lying. After being subjected to force during a fall, it has a certain strength, forming a protective layer to dissipate and absorb impact force, thereby reducing the damage to the hip caused by a fall or other impact force. Wearing the pad body of this design on both sides of the hip can play a good protective role, has good shock absorption and anti-collision effects, is easy to use, and can significantly reduce the degree of damage to the hip fracture and reduce the risk of hip fracture in a fall or other traumatic events to the hip.

[0020] The design of the spacing grooves on the pad body ensures that the pad body can adjust and deform with the human body's movements, so that it can adapt to various postures such as walking, sitting, and lying, ensuring the freedom and smoothness of daily movements; the design of multiple ventilation holes achieves a breathable effect and avoids stuffiness. The shape of the pad body fits perfectly with the hip bones, which can increase the force-bearing area when falling. BRIEF DESCRIPTION OF THE DRAWINGS
