Description

Technical Field

[0001] This utility model relates to the field of medical and nursing auxiliary equipment technology, specifically to a restraint belt for bed and chair. Background Technology

[0002] Currently, restraint belts are widely used as assistive fixation tools in medical care and home care scenarios. They are mainly used to safely restrain people with limited mobility, cognitive impairment, or children to prevent injuries caused by falls from bed, accidental falls, or involuntary movements.

[0003] Existing restraint straps typically consist of a strap that contacts the body and a fixing structure for connecting to bed frames or chairs. The strap is often made of webbing, and the fixing structure is connected to the support via straps, buckles, or Velcro. However, in actual use, the following shortcomings often exist: the connection between the strap and the bed frame or chair lacks effective restraint, and even slight movements by the user can cause the restraint strap to shift, affecting the fixation effect; in addition, due to the large differences in user body shapes, a fixed length of restraint strap may be "too loose," and the restraint strap is prone to redundant structures, which not only affect the fixation effect but may also reduce safety.

[0004] To address the above problems, there is an urgent need to propose a bed and chair restraint strap solution. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a bed and chair restraint strap to solve the problems of insufficient fixation stability, limited adaptability and poor comfort of existing restraint straps.

[0006] To achieve the above objectives, this utility model provides a restraint strap for a bed and chair, comprising:

[0007] The constraint band has a rough surface on its inner side and a hooked surface on its outer side, which can be bonded together.

[0008] The binding strap, the middle of which is connected to the outer side of the restraint strap;

[0009] The strap has a buckle structure, and the two ends of the strap are fixedly connected by a buckle structure.

[0010] Preferably, a cloth strip is sewn into the middle of the outer side of the restraint strap to form a ring-shaped opening through which the strap passes.

[0011] Preferably, the outer side of the restraint band is recessed inward to form a positioning groove for the strap to be inserted;

[0012] The positioning groove runs through the length of the constraint belt and passes through the fabric belt.

[0013] Preferably, the inner side of the strap is provided with anti-slip silicone particles.

[0014] Preferably, the inner rough surface and the outer hook surface of the constraint band are fixed by sewing.

[0015] Preferably, the constraint band hooks are distributed on both sides of the positioning groove.

[0016] Preferably, the male and female ends of the buckle structure are respectively located at both ends of the strap.

[0017] Preferably, the outer layer of the restraint strap is a high-strength webbing, and the inner layer is a buffer layer, which are fixed together by hot melt adhesive and / or stitching.

[0018] The beneficial effects of this utility model are:

[0019] This invention solves the adaptability problem caused by the fixed length of traditional restraint straps by using a design that bonds the rough and hook surfaces of the restraint straps. By rolling and adjusting, it can adapt to different body shapes from children to adults. At the same time, the positioning effect formed by the cylindrical structure prevents the restraint straps from slipping during use. The two ends of the strap with anti-slip silicone particles are wrapped around the support structure of the bed frame or chair and fixed by the male and female heads of the buckle structure. Thus, it provides a simple, firmly fixed, and adaptable bed and chair restraint device that can be used by users of different body shapes. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] This utility model proposes a restraint strap for beds and chairs, such as... Figures 1 to 3 As shown, it includes a restraint strap body 1, a strap 2, and a buckle structure. The restraint strap body 1, as the part that directly contacts the human body, has a rough surface 11 on its inner side and a hook surface 12 on its outer side. The rough surface 11 and the hook surface 12 can be bonded together. With this design, when facing a user with a smaller body size, the two ends of the restraint strap body 1 can be rolled inward and formed into a cylinder by bonding the rough surface 11 and the hook surface 12, effectively eliminating structural redundancy. At the same time, the cylinder structure can provide stable positioning for the human body and prevent the restraint strap body 1 from shifting.

[0029] The middle part of the strap 2 is connected to the outer side of the restraint strap body 1. To enhance the stability of the connection, a fabric strip 5 is sewn into the middle of the outer side of the restraint strap body 1. The fabric strip 5 forms an annular opening. After the strap 2 passes through this annular opening, it connects with the restraint strap body 1, making the relative position of the strap 2 and the restraint strap body 1 more stable. Furthermore, the outer side of the restraint strap body 1 is recessed inward to form a positioning groove. The positioning groove passes through the fabric strip 5 along the length of the restraint strap body 1. The strap 2 is embedded in the positioning groove. Through the limiting effect of the positioning groove, the strap 2 can be prevented from sliding left and right during use, ensuring that the strap 2 is always in an effective working position.

[0030] To prevent relative slippage between the strap 2 and the bed frame or chair, anti-slip silicone particles 21 are distributed on the inner side of the strap 2. These particles increase the friction between the strap 2 and the supporting structure, significantly improving the fixation effect. The hook surfaces 12 on the outer side of the restraint strap 1 are distributed on both sides of the positioning groove. This layout ensures effective adhesion between the rough surface 11 and the hook surface 12 when the restraint strap 1 is rolled up, while preventing the hook surface 12 from covering the positioning groove and affecting the insertion and use of the strap 2.

[0031] The inner rough surface 11 and the outer hook surface 12 of the restraint strap body 1 are fixed by sewing. The two ends of the strap 2 are connected by a buckle structure. The male head 3 and the female head 4 of the buckle structure are respectively set at the two ends of the strap 2. The strap 2 can be quickly fixed and removed by buckling, which is convenient to operate and allows nursing staff to quickly complete the wearing and adjustment of the restraint strap.

[0032] The restraint strap 1 adopts a composite structure design (not shown in the figure). The outer layer is a high-strength webbing that provides sufficient tensile strength to ensure restraint effectiveness. The inner layer is a buffer layer that effectively disperses the pressure of the restraint strap 1 on the human body, improving user comfort. The outer and inner layers are fixed together with hot melt adhesive and / or stitching, ensuring the strong connection between the layers and adapting to the strength requirements of different usage scenarios, thus avoiding delamination.

[0033] The above technical solution achieves stable constraints and flexible adaptation based on the coordinated cooperation of various components.

[0034] In use, first, attach the restraint strap 1 to the part of the body that needs to be fixed. Adjust the length of the restraint strap 1 according to the user's body size: if the user is small, roll both ends of the restraint strap 1 inward so that the inner rough surface 11 and the outer hook surface 12 are bonded together to form a roll shape, eliminating excess length and providing auxiliary positioning for the body through the roll structure; then ensure that the strap 2 is embedded in the positioning groove, so that the strap 2 and the restraint strap 1 are tightly fitted and do not shift; next, wrap both ends of the strap 2 around the support structure of the bed frame or chair, and fasten them with the male end 3 and female end 4 of the buckle structure to achieve fixation. At this time, the anti-slip silicone particles 21 on the inner side of the strap 2 are in close contact with the surface of the support structure, preventing the entire device from shifting through friction. Throughout the process, the composite structure of the restraint strap 1 ensures safe restraint for the human body while reducing skin pressure through the buffer layer; the rough surface 11 and hook surface 12 can also be connected to the restraint strap 1 in a detachable manner to allow for partial replacement according to wear and tear, extending the product's service life.
