Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical environment safety protection equipment technology, specifically to a collision-proof corner protection device for psychiatric wards. Background Technology
[0002] Patients with mental illness may experience emotional agitation, behavioral disturbances, impulsive aggression, or self-harm due to their condition, such as suddenly accelerating and running, or violently colliding with walls or corners. Corners (the sharp angles formed by the intersection of two walls or a wall and the ground) are high-risk areas for serious injuries in such accidental collisions due to their prominent hard structure. Common injuries include head hematomas, fractures, and skin lacerations, causing not only pain and increasing the medical burden on patients but also potentially leading to medical disputes. The existing technology has the following problems: Common corner protection measures in the market and wards mainly include using soft materials such as sponge and EVA foam to make strips or right angles, which are then pasted to the corners with double-sided tape. Although these products are inexpensive and easy to install, they have significant drawbacks in psychiatric wards. Patients may deliberately tear or dig when they are emotionally agitated, or the adhesive layer may fail due to frequent and violent collisions, causing the protective layer to fall off and lose its protective function. In addition, the soft foam material itself is easily torn or disassembled by patients with their hands, teeth, or other hard objects, and may even be swallowed, posing a safety hazard. Alternatively, simple soft pouches can be used, which are made by sewing right angle sleeves with sponge or other filling materials wrapped in cloth and placed on the corners. Although this is slightly better than the adhesive type, it mainly relies on friction or simple ties for fixation. Under strong impact or pulling, it is very easy to shift or fall off, and the cloth is easily worn and torn, and the filling material may leak out or be removed. Utility Model Content
[0003] This invention provides a corner protection device for psychiatric wards to address the problems mentioned in the background section.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A corner protection device for psychiatric wards includes a corner protection mechanism. Sealing silicone is provided on both the upper and lower sides of the corner protection mechanism. The corner protection mechanism includes a right-angled aluminum alloy backing plate. A right-angled polyethylene foam is fixedly installed on the outer wall of the right-angled aluminum alloy backing plate. A right-angled high-density polyethylene is fixedly installed on the outer wall of the right-angled polyethylene foam. Two sealing silicone sealants are respectively fixedly bonded to the upper and lower sides of the outer wall of the right-angled high-density polyethylene. Several bolt holes are evenly distributed on the outer sides of the two right-angled sides of the right-angled aluminum alloy backing plate. Each bolt hole has a through hole extending to the inner side of the right-angled side of the right-angled aluminum alloy backing plate. A stainless steel bolt rod is inserted through the inner circle of the through hole. One end of the stainless steel bolt rod is located inside the bolt hole cavity and a Torx bolt head is fixedly installed. The inner circle of the bolt hole is fixedly filled with epoxy resin sealant.
[0005] A further improvement of this utility model is that: the right-angled polyethylene foam is uniformly provided with several honeycomb-shaped holes, and the right-angled polyethylene foam completely covers the outer wall of the right-angled aluminum alloy liner that is not attached to the wall.
[0006] A further improvement of this utility model is that: the two right-angled sides of the right-angled polyethylene foam are each uniformly provided with a number of through-holes, and the number of through-holes are respectively connected to a number of bolt holes.
[0007] A further improvement of this utility model is that: the outer wall of the right-angled high-density polyethylene is fixedly coated with a hydrophobic coating, and the right-angled high-density polyethylene completely wraps the right-angled polyethylene foam away from the outer wall of the right-angled aluminum alloy liner.
[0008] A further improvement of this utility model is that: the two right-angled sides of the right-angled high-density polyethylene are each uniformly provided with a plurality of second docking holes, and the plurality of second docking holes are respectively connected to the plurality of first docking holes.
[0009] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model provides a collision-resistant corner protection device for psychiatric wards. It adopts a three-layer composite structure of right-angle aluminum alloy backing plate, right-angle polyethylene foam, and right-angle high-density polyethylene, which are fused together into a seamless whole under high temperature and pressure. The outer layer is 2mm thick medical-grade high-density polyethylene with a smooth, non-porous, and tear-resistant surface, and is coated with a hydrophobic coating. The internal structure is anchored to the wall with stainless steel bolts, and the bolt holes are filled with epoxy resin sealant. The bolt heads are designed with a hidden staggered structure, which solves the defects of double-sided adhesive protection that is easy to tear off and the soft cloth covering that is easy to wear and the filling material that can be removed. Through rigid anchoring and tear-resistant materials, it prevents the device from shifting or disintegrating due to intentional damage by patients or accidental impacts, ensuring that the protection is durable and effective.
[0010] This invention provides a corner protection device for psychiatric wards. By using 30mm closed-cell cross-linked polyethylene foam in the middle layer with uniformly distributed honeycomb-shaped pores, it can efficiently disperse impact energy. Combined with the rigid support of the outer HDPE layer, it achieves a combination of rigidity and flexibility, solving the shortcomings of insufficient cushioning performance of ordinary sponge or EVA foam. The honeycomb structure significantly improves energy absorption efficiency, reducing the risk of head injuries and fractures caused by patients hitting corners. It is especially suitable for high-intensity collision scenarios in psychiatric wards. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand Understood. The present invention will now be further described in conjunction with specific implementation methods.
[0014] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a corner protection device for psychiatric wards, including a corner protection mechanism 1. Sealing silicone 2 is provided on both the upper and lower sides of the corner protection mechanism 1. The corner protection mechanism 1 includes a right-angle aluminum alloy backing plate 11, made of 1.5mm anodized aluminum alloy material, providing rigid support to prevent overall deformation of the device and avoid the formation of new dangerous protrusions. A right-angle polyethylene foam 12 is fixedly installed on the outer wall of the right-angle aluminum alloy backing plate 11, and a right-angle high-density polyethylene 13 is fixedly installed on the outer wall of the right-angle polyethylene foam 12. Two sealing silicone 2 are respectively fixedly bonded to the upper and lower sides of the outer wall of the right-angled high-density polyethylene 13. Several bolt holes 111 are evenly opened on the outer sides of the two right-angled sides of the right-angled aluminum alloy liner 11. The inner walls of the bolt holes 111 are all opened with through holes 112 that penetrate to the inner side of the right-angled sides of the right-angled aluminum alloy liner 111. A stainless steel bolt rod 113 is installed through the inner ring of the through hole 112. One end of the stainless steel bolt rod 113 is located in the inner cavity of the bolt hole 111 and is fixedly installed with a Torx bolt head 114. The inner ring of the bolt hole 111 is fixedly filled with epoxy resin sealant 115. The three-layer structure of right-angle aluminum alloy backing plate 11, right-angle polyethylene foam 12, and right-angle high-density polyethylene 13 is hot-melted and laminated in a hot press to form a seamless whole. The edges are transitioned with a large arc, and the bottom extends downward to the ground to form a 15cm high skirting board for protection, preventing patients from kicking the base of the wall corner. During installation, first determine the height of the wall corner, and cut the device to the matching size. The standard height is 2.2m. Drill deep holes 10cm from the edge on both sides of the wall corner. Place the right-angle aluminum alloy backing plate 11, which is included in the device, tightly against the wall corner. Drive stainless steel bolts 113 into the wall hole through the through holes 112 in the bolt holes 111 of the right-angle aluminum alloy backing plate 11. Using a Torx screwdriver, align the Torx head 114 with the Torx groove and tighten the stainless steel bolt shank 113 until the Torx head 114 is engaged in the bolt hole 111, ensuring zero gap between the right-angle aluminum alloy backing plate 11 and the wall. Then, inject epoxy resin sealant 115 into the bolt hole 111 and smooth the surface for sealing. Finally, seal the gap between the top and bottom of the right-angle high-density polyethylene 13 and the ceiling and floor with silicone sealant 2 to form a sterile closed environment, thus completing the installation. The silicone sealant 2 is medical-grade silicone, with a coating thickness of 3mm, and is cured at room temperature for 24 hours. After curing, it passes the airtightness test.
[0015] like Figure 4 As shown, the right-angled polyethylene foam 12 has a number of honeycomb-shaped holes 121 evenly distributed. The honeycomb-shaped holes 121 are regular hexagons and are evenly distributed along the right-angled side. The right-angled polyethylene foam 12 completely covers the outer wall of the right-angled aluminum alloy backing plate 11 that is not attached to the wall. The two right-angled sides of the right-angled polyethylene foam 12 each have a number of through holes 122 that are connected from front to back. The through holes 122 are connected to the bolt holes 111 from front to back. The right-angle polyethylene foam 12 is made of 30mm thick closed-cell cross-linked polyethylene foam. The honeycomb-shaped pores 121 can be used for impact buffering, effectively absorbing collision kinetic energy and dispersing impact force, far exceeding ordinary sponges. The mating hole 122 opened in the right-angle polyethylene foam 12 does not prevent the stainless steel bolt rod 113 from passing through, and the diameter is 10mm to prevent fingers from sticking in.
[0016] like Figure 5 As shown, the outer wall of the right-angled high-density polyethylene 13 is fixedly coated with a hydrophobic coating 132, which prevents blood and body fluids from penetrating and can be directly rinsed with chlorine-containing disinfectant. The right-angled high-density polyethylene 13 completely wraps the right-angled polyethylene foam 12 away from the outer wall of the right-angled aluminum alloy liner 11. Several docking holes 131 are evenly opened on the two right-angled sides of the right-angled high-density polyethylene 13, and the several docking holes 131 are connected to several docking holes 122 from front to back. The right-angled high-density polyethylene 13 is made of 2mm thick medical-grade high-density polyethylene material. The surface is smooth and non-porous, impact-resistant, tear-resistant, and flame-retardant with a B1 rating. It is tear-resistant and smooth, so patients cannot tear it or use it to climb over it. It is easy to clean and disinfect. The docking hole 131 of the right-angled high-density polyethylene 13 can also be directly passed through the stainless steel bolt rod 113. The diameter is 10mm, which prevents patients from inserting their fingers.
[0017] The working principle of the anti-collision corner protection device used in this psychiatric ward will be explained in detail below.
[0018] like Figure 1-5As shown, the three-layer structure of right-angle aluminum alloy backing plate 11, right-angle polyethylene foam 12, and right-angle high-density polyethylene 13 is fused together at high temperature to form a seamless whole. The edges are transitioned with a large arc, and the bottom extends downward to the ground to form a 15cm high skirting board for protection, preventing patients from kicking the base of the wall corner. During installation, first determine the height of the wall corner, and cut the device to the matching size. The standard height is 2.2m. Drill deep holes 10cm from the edge on both sides of the wall corner, and fit the right-angle aluminum alloy backing plate 11 tightly against the wall corner. Stainless steel bolt shanks 113 are driven into the wall hole through the through hole 112 in bolt hole 111. Using a Torx screwdriver, the bolt shank 113 is tightened into the Torx groove of the Torx bolt head 114 until the Torx bolt head 114 is fully engaged in the bolt hole 111, ensuring zero gap between the right-angle aluminum alloy backing plate 11 and the wall. Then, epoxy resin sealant 115 is injected into the bolt hole 111, and the surface is smoothed for sealing. Finally, silicone sealant is applied to the gap between the top and bottom of the right-angle high-density polyethylene 13 and the ceiling / floor. The installation is completed by sealing with adhesive to form a sterile closed environment. The right-angle high-density polyethylene 13 is made of 2mm thick medical-grade high-density polyethylene material with a smooth, non-porous surface. It is impact-resistant, tear-resistant, and flame-retardant (B1 grade). It is tear-resistant and smooth, so patients cannot tear it or use it for climbing. It is easy to clean and disinfect. The right-angle polyethylene foam 12 is made of 30mm thick closed-cell cross-linked polyethylene foam. It can buffer impacts using honeycomb-shaped pores 121. After repeated impacts, the permanent deformation rate is <5%, and the energy absorption rate is >85%. It efficiently absorbs collision kinetic energy and disperses impact force, far exceeding ordinary sponges. The right-angle aluminum alloy liner 11 is made of 1.5mm anodized aluminum alloy material, providing rigid support, preventing the overall deformation of the device, and avoiding the formation of new dangerous protrusions. The first docking hole 122 of the right-angle polyethylene foam 12 does not obstruct the passage of the stainless steel bolt rod 113 and has a diameter of 10mm to prevent fingers from being inserted. The second docking hole 131 of the right-angle high-density polyethylene 13 can also directly pass through the stainless steel bolt rod 113 and has a diameter of 10mm to prevent patients from inserting their fingers.
[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
