Description

Technical Field

[0001] This utility model relates to the field of medical device accessories or transport bed and safety, specifically to an anti-tipping protective fence for hospital transport beds. Background Technology

[0002] Hospital transport beds (also known as stretchers) are the core equipment for short-distance patient transport within a hospital. Their bed boards typically have standardized cylindrical insertion holes on both sides, primarily for mounting IV stands.

[0003] Currently, in this field, the existing technical solutions and their shortcomings regarding the prevention of tipping over of the bed board of a transfer bed are as follows: 1. Structural reinforcement solutions: A common approach is to increase the structural strength of the bed board itself, such as by using thicker boards or reinforcing the edges of the bed board. However, this solution has the drawback of significantly increasing the overall weight and manufacturing cost of the transfer bed, placing a greater physical burden on medical staff when pushing the bed, and failing to solve the fundamental problem of tipping over.

[0004] 2. Insufficient utilization of existing sockets: Currently, the IV stand sockets on the bed board have a very limited function, only used for receiving IV stands. There is no existing technical solution in the field that can cleverly utilize this existing, standardized interface to extend the bed with crucial safety protection functions. This represents a functional waste of the existing structure.

[0005] Therefore, the core shortcomings of existing technologies are: high cost (corresponding to structural reinforcement solutions); poor protection / weak responsiveness (unable to effectively cope with collisions and rollovers); and limited functionality (corresponding to structures that fail to effectively utilize the sockets). Figure 1 Mark 3 indicates the location of the IV stand insertion hole; while mark 5 indicates the rotatable bed board. During prolonged use, the bed board is prone to loosening and deformation, which may pose a significant risk of patients falling out of bed.

[0006] This invention aims to solve the problems of physical protection and stability at the mechanical structure level, and solves the two core safety issues of "protection" and "anti-rollover". Existing solutions have failed to solve these two problems simultaneously, efficiently and at low cost. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a protective fence against tipping over for hospital transport beds. The device has a simple structure, provides effective protection, prevents tipping over, and solves the two core safety problems of "protection" and "prevention of tipping over" by utilizing existing sockets.

[0008] Therefore, this utility model proposes an anti-tipping protective fence for hospital transport beds, comprising: The fence assembly includes a horizontal bar and two vertical bars connected to the two ends of the horizontal bar respectively; the lower part of the two vertical bars is provided with a pin section, which is used to insert into the infusion stand insertion hole prefabricated on the transfer bed body to realize the rigid connection between the fence assembly and the bed body. The upper part of the first vertical rod is also provided with a socket section, which is used to receive the infusion stand; the horizontal rod is connected to the first vertical rod and the second vertical rod respectively through an arc-shaped connecting rod, so that the horizontal rod is offset from the first vertical rod and the second vertical rod in the horizontal direction.

[0009] Preferably, it also includes a shelf assembly, which is rotatably mounted on the outside of the fence assembly and can switch between an unfolded state and a folded state.

[0010] Preferably, the shelf assembly includes a shelf body, a first rotating component, a diagonal brace, an arc-shaped support plate, and a second rotating component; one inner end of the shelf body is rotatably connected to the crossbar via the first rotating component; the movable end of the shelf body is connected to the diagonal brace via the second rotating component; the end of the diagonal brace is provided with the arc-shaped support plate, the shape of which is adapted to the lower outer surface of the crossbar, for providing stable support when the shelf assembly is unfolded.

[0011] Preferably, the rotating component is a sleeve structure, the inner radius of which matches the outer diameter of the upper crossbar in the crossbar, so that the two rotate coaxially.

[0012] Preferably, the second rotating component is a hinge, and its two rotating blades are welded to the shelf body and the diagonal brace or fixedly connected by screws or anchors.

[0013] Preferably, the fence assembly further includes reinforcing ribs disposed on the crossbar or connected between components of the crossbar.

[0014] Preferably, the pin segment is locked by a locking bolt after being inserted into the prefabricated infusion stand socket.

[0015] Preferably, the fence assembly is made of stainless steel.

[0016] The anti-tipping protective fence for hospital transport beds provided by this utility model is achieved by setting up a rigid fence assembly and fixing it with the existing IV stand insertion holes on the bed. The ingenious concept of combining the rigid protective fence with standardized insertion hole interfaces is realized with specific and optimized structures (such as fences with reinforcing ribs, cylindrical pin rods, double-point fixing, etc.), which successfully provides a comprehensive solution that can simultaneously take into account low cost, high efficiency protection, active anti-tipping, and make full use of existing structures.

[0017] In a preferred embodiment of this invention, the functionality is further expanded by incorporating a foldable shelf assembly. While providing protection, it also offers a convenient storage platform for medical personnel, and can be folded away when not in use, saving space. This invention, through its simple structure and full utilization of existing interfaces on the transfer bed, achieves multiple objectives including protection, anti-tipping, and expanded storage functionality, demonstrating significant beneficial effects.

[0018] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3As shown, the anti-tipping protective fence for hospital transport beds of this utility model combines rigid protection with the existing standardized interface (IV stand insertion hole 3) on the transport bed through a simple and ingenious connection structure, creating a low-cost, high-efficiency, and comprehensive device that combines safety protection and anti-tipping functions. Specifically, the device includes: a vertical protective plate (in this embodiment, it is manifested as a fence assembly 6 with reinforcing ribs); and at least one rigid locking part fixed to the inside of the protective plate for insertion and locking into the IV stand insertion hole 3 of the transport bed (in this embodiment, it is manifested as a cylindrical metal rod pin section 631 at the lower part of the vertical rod).

[0022] The anti-tipping protective fence includes a fence assembly 6 and a shelf assembly 8. The fence assembly 6 serves as the core vertical rigid protective plate. Its two ends (the pin sections 631 at the bottom of vertical rod 1 62 and vertical rod 2 63) are inserted into the pre-fabricated IV stand insertion holes 3 in the bed frame 1, thus achieving a secure assembly between the entire fence assembly 6 and the bed frame 1. The bottom of the bed frame 1 is equipped with multiple support legs. Using two or more locking parts is a preferred embodiment of this solution, as it can evenly distribute lateral forces to multiple stress points on the bed frame, greatly enhancing the stability of the connection and the overall anti-tipping capability.

[0023] The IV stand 7 is inserted into the insertion hole 632 at the upper end of one of the vertical bars, which reflects the expansion of its function. The shelf assembly 8 is movably installed on the outside of the fence assembly 6. It can be unfolded when needed and folded up when not needed, without taking up space or affecting the operation of medical staff.

[0024] Specifically, the fence assembly 6 mainly includes two vertical rods 62 and 63 at both ends, a horizontal rod 61, a reinforcing rib 64, and an arc-shaped connecting rod 65. The first vertical rod 62 and the second vertical rod 63 are solid stainless steel tubes or hollow stainless steel tubes with sealed tops. Their outer diameter matches the size of the infusion stand insertion holes 3. They are inserted into the two pre-made infusion stand insertion holes 3 on the bed body 1 and fixed by the locking bolts 4 on the side of the infusion stand insertion holes 3, thus achieving a stable assembly between the entire fence assembly 6 and the bed body 1.

[0025] The two ends of the crossbar 61 are welded to the first vertical bar 62 and the second vertical bar 63 respectively via arc-shaped connecting rods 65. The arc-shaped connecting rods 65 cause the crossbar 61 to deviate from the first vertical bar 62 and the second vertical bar 63 by a certain distance in the horizontal direction, thereby offsetting the crossbar 61 from the rotatable side plate 5 in the width direction of the bed body 1 and avoiding assembly interference. At the same time, the crossbar 61 includes a horizontally arranged upper crossbar and a lower crossbar, which are connected by a bent pipe and a reinforcing rib 64 to meet the strength requirements.

[0026] Vertical rod 1 (62) and vertical rod 2 (63) have similar structures, both having a middle section and a lower pin section (631). Vertical rod 1 (62) also has an insertion hole section (632) at the upper end of the middle section. The insertion hole section (632) is a hollow round tube, into which the IV stand 7 can be inserted for easy hanging of the IV bag by medical personnel. The specific implementation of the locking part is a cylindrical metal rod, namely the solid or thick-walled hollow stainless steel tube section (pin section 631) at the lower part of vertical rod 1 (62) and vertical rod 2 (63). Its outer diameter is precisely matched with the standardized IV stand insertion hole 3 to ensure a tight insertion and a wobbly connection.

[0027] The device of this invention is specifically designed for two core applications: preventing the bed board of the transfer bed from tipping over and protecting the edge of the bed board from bumps and knocks.

[0028] Achieving efficient protection: In the event of a side collision, the rigid stainless steel fence assembly 6 with reinforcing ribs 64 acts as the first line of defense, effectively resisting, absorbing, and dispersing the impact force. The impact force is transmitted through the fence structure to the vertical bars (62, 63), and then through their cylindrical pin sections 631 to the robust bed frame 1, preventing the vulnerable edges of the bed board (especially the rotatable side panels 5) from direct stress, fundamentally solving the problem of insufficient protection capability of flexible anti-collision strips.

[0029] Active anti-tipping mechanism: The key lies in rigid connection and height design. First, through at least one (two in this embodiment) tightly fitting pin section 631 and infusion stand insertion hole 3, the fence assembly 6 and bed frame 1 form a stable whole. Second, the overall height of the fence assembly 6 is significantly higher than the bed board plane. This "heightened design" can provide a strong resisting support torque through the lever principle when the bed frame tends to tilt. The design of multiple locking parts further ensures that the support torque can act stably and evenly on the bed frame, significantly enhancing lateral stability and effectively preventing tipping.

[0030] like Figure 2 , Figure 3 As shown, the IV stand insertion hole 3 shelf assembly 8 includes: a shelf body 81, a first rotating component 82, a diagonal brace 83, an arc-shaped support plate 84, and a second rotating component 85. Its unfolding and folding mechanism, as described above, provides a convenient storage platform without affecting the main body's protective function.

[0031] One end of the inner side of the shelf body 81 is rotatably connected to the upper crossbar of the crossbar 61 through a rotating component 82. The rotating component 82 is a sleeve structure, and its inner radius matches the outer diameter of the upper crossbar of the crossbar 61, so that the two rotate coaxially.

[0032] The movable end of the shelf body 81 is connected to the diagonal brace 83 via a rotating component 85. The rotating component 85 is a hinge, and its two rotating blades are welded to the shelf body 81 and the diagonal brace 83 or fixedly connected by screws or anchors.

[0033] The end of the diagonal brace 83 is connected to an arc-shaped support plate 84. The shape of the arc-shaped support plate 84 matches the outer radius of the lower crossbar in the crossbar 61, so that the arc-shaped support plate 84 is supported on the outer cylindrical surface of the lower crossbar without sliding, thereby making the diagonal brace 83 and the shelf body 81 stable in the unfolded state.

[0034] Compared with the prior art, this embodiment achieves the following significant improvements through the specific structure described above: Addressing the issues of "high cost and need for modification": This device is an independent, modular accessory with a simple structure (mainly rods and sheet metal), easy manufacturing process, and low production cost. It requires no changes to the main structure of the transfer bed, utilizing existing sockets for "plug-and-play" operation, avoiding increases in bed weight and cost, and significantly lowering the barrier to entry for use.

[0035] To address the issue of "poor protective effect": the rigid stainless steel fence structure provides an active and reliable physical barrier, whose protective effect is far superior to that of passively attached flexible anti-collision strips.

[0036] To address the issue of "lack of anti-tipping function": through the tight fit between the rigid snap-fit ​​part (pin section) and the bed frame insertion hole, and the design of the protective fence being higher than the bed board, the device is firmly integrated with the bed frame to form an effective anti-tipping support mechanism, filling the functional gap of the existing technology.

[0037] To address the issue of "single-function sockets": the standard IV stand socket 3 is creatively expanded into a security interface, achieving "multi-purpose use of one socket" (both for inserting the IV stand 7 and the protective railing), improving the utilization rate and economic value of the existing standardized structure, and demonstrating the creativity of this invention.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
