Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a non-restraint fall-prevention bed safety cover. Background Technology

[0002] In medical care settings, preventing patients (especially those who are unconscious, immobile, or post-operative) from falling out of bed is a crucial safety requirement. Traditional fall prevention measures mainly rely on bed rails or restraint straps. Bed rails offer limited physical protection, while restraint straps provide protection by binding the patient's limbs, but this is a form of mandatory restraint. For example, Chinese utility model patent CN212592796U discloses a restraint bed, including a bed frame with a first bed board and a second bed board arranged side-by-side on the frame. The second bed board is fixed to the bed frame, and the end of the first bed board near the second bed board is hinged to the middle of the bed frame. A height adjustment device is provided between the first bed board and the lower part of the bed frame. The first bed board has upper limb restraint straps and shoulder restraint straps, and the second bed board has lumbar restraint straps and lower limb restraint straps, arranged sequentially. In practical application, the solution has revealed some issues that need optimization: for example, directly binding the patient's limbs with restraint straps may cause discomfort, skin damage, or psychological stress, while also restricting the patient's autonomous movement; furthermore, the device lacks windproof functionality; and in emergency situations, it may not be able to be quickly removed, thus affecting rescue efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example: A non-restrained fall-prevention bed safety cover, configured as follows Figure 1 and 2As shown, the device is installed on a hospital bed, which includes an upper railing 1, a lower railing 2, a left railing 3, and a right railing 4. The left railing 3 has a left stop bar 5, and the right railing 4 has a right stop bar 6. The hospital bed has multiple male latches 7, each with a female latch 8 that engages with it. The male latches 7 are respectively fixed to the upper railing 1, lower railing 2, left railing 3, left stop bar 5, right railing 4, and right stop bar 6. Figure 3As shown, the lower end of the male buckle 7 has a first connecting part 10, and one end of the first connecting part 10 is hinged to an annular clamp 11. The other end of the first connecting part 10 and the annular clamp 11 forms an opening 12. The other end of the first connecting part 10 is provided with a first threaded hole 13, and the other end of the annular clamp 11 is provided with a second threaded hole 14 that mates with the first threaded hole 13. The other end of the annular clamp 11 is also provided with an adjusting bolt 15. The first connecting part 10 has a first semi-circular groove 16, and the annular clamp 11 has a second semi-circular groove 17. The adjusting bolt 15 closes the opening 12 by threading with the first threaded hole 13 and the second threaded hole 14, so that a fixing hole is formed between the first semi-circular groove 16 and the second semi-circular groove 17. The fixing hole is respectively fitted onto the upper fence 1, the lower fence 2, the left fence 3, the left stop 5, the right fence 4, and the right stop 6. The first connecting part 10 forms an openable and closable annular clamp 11 through a hinged structure, which is fitted onto the bed railing and guardrail. The opening 12 is closed by adjusting the bolt 15, allowing the first semi-circular groove 16 and the second semi-circular groove 17 to form a fixing hole, achieving a ring-shaped fixation of the bed components. Furthermore, the size of the fixing hole can be adjusted according to the diameter of the bed components (e.g., the thickness of the railing for different bed models), improving the adaptability and installation flexibility of the device. The male buckle 7 has a first engaging part 18 at its upper end, with a protrusion at the end of the first engaging part 18. The female buckle 8 has a second engaging part 19, with a groove that mates with the protrusion. Through the engagement of the protrusion and the groove, the safety cover 9 is quickly and securely fastened to the bed. Limiting plates 20 are provided at both the upper and lower ends of the first engaging part 18, abutting against the second engaging part 19, thereby limiting the displacement of the second engaging part 19 and enhancing the stability of the structure. The second snap-fit ​​part 19 has fixing parts 21 on both sides that cooperate with the male snap-fit ​​7 to fix the safety cover 9. These parts are used to clamp the edge of the connection hole 25 of the safety cover 9, preventing the safety cover 9 from loosening or falling off at the snap-fit ​​point. This device uses multi-dimensional clamping from the top and bottom (limiting plate 20) and both sides (fixing parts 21) to fix the connection hole 25 of the safety cover 9 between the male snap-fit ​​7 and the female snap-fit ​​8, ensuring that the safety cover 9 is stable and reliable in both the vertical direction (preventing falling off) and the horizontal direction (preventing lateral displacement). The safety cover 9 is also provided on the hospital bed. The safety cover 9 is made of polyester fiber, which has the characteristics of breathability, wear resistance, and easy cleaning, facilitating daily disinfection and maintenance in the hospital, while ensuring the durability of the protective structure. The safety cover 9 is fixed to the hospital bed by the snap-fit ​​cooperation of the male snap-fit ​​7 and the female snap-fit ​​8. Specifically, the safety cover 9 has multiple connection holes 25 that mate with the male buckle 7. The first snap-fit ​​part 18 passes through the connection hole 25. The connection hole 25 serves as the connection interface between the safety cover 9 and the buckle structure, allowing the safety cover 9 to be fixed to the perimeter of the hospital bed via snap-fit. The safety cover 9 divides the hospital bed into a central restraint zone 901 and windproof zones 902 on the front and rear sides. The restraint zone 901 covers the central perimeter of the hospital bed, forming a physical barrier higher than the bed surface. It restricts the patient from moving excessively towards the edge of the bed through flexible blocking, avoiding the risk of falling out of bed and replacing the forced restraint of traditional restraint straps.The 902 windproof zone covers the front, rear, and sides of the bed, blocking external airflow (such as air conditioning or natural wind) from directly blowing on the patient's body. It is especially suitable for keeping postoperative patients warm and improving nursing comfort. See attached. Figure 3 As shown, connecting ropes 23 are connected in series between the female buckles 8. Each female buckle 8 has a connecting ring 22 that is fixedly connected to the connecting ropes 23. The connecting ropes 23 connect all the female buckles 8 on the same side together. To better connect the connecting ropes 23 to the female buckles 8, the following method can be used: Figure 3 As shown, after passing through the connecting ring 22, a single knot is tied. In an emergency, medical staff can pull the connecting rope 23 to quickly pull the female buckle 8 in the direction of the arrow, separating the protrusion from the groove, thus enabling tool-free quick disassembly of the safety cover 9 and buying time for rescue. The safety cover 9 is equipped with magnetic strips 24 at the bottom that magnetically engage with the edge of the hospital bed. The magnetic strips 24 are evenly distributed along the bottom edge of the safety cover, forming multi-point fixation with the bed edge. This not only prevents the safety cover 9 from flipping upwards or shifting sideways due to patient movement but also effectively blocks airflow from entering from the bottom, enhancing windproof performance.

[0021] This invention uses a safety cover 9 to create physical isolation, replacing traditional restraint straps. This avoids direct binding of the patient's limbs, reduces skin damage and psychological stress, and ensures the patient's freedom of movement. The safety cover 9 divides the bed into a central restraint zone 901 and front and rear side windproof zones 902. While preventing falls from the bed, it also blocks direct airflow from blowing on the patient, making it particularly suitable for postoperative or frail patients and improving the comfort of the nursing environment. Furthermore, this invention employs a snap-fit ​​structure between a male buckle 7 and a female buckle 8. During installation, the buckle is secured by the interlocking of protrusions and grooves. Disassembly is simple: just pull the connecting rope 23 to release the snap-fit ​​and quickly remove the safety cover 9, eliminating the need for complex operations and meeting the rapid response requirements in emergency rescue scenarios. The male buckle 7 is fixed to the bed railing and guardrail by a ring clamp 11 and adjusting bolts 15. The size of the fixing hole can be adjusted according to different bed dimensions, offering strong adaptability. The magnetic strip 24 below the safety cover 9 magnetically engages with the bed edge, further enhancing bottom stability and preventing the safety cover 9 from shifting due to patient movement. The safety cover 9 of this utility model is made of polyester fiber material, which is breathable, wear-resistant and easy to clean. It can not only ensure the protective effect, but also facilitate the daily disinfection and maintenance of the hospital.

[0022] Work process

[0023] The annular clip 11 of the male buckle 7 is fitted onto the bed railings 1, 2, 3, 5, 4, and 6, aligning the first semi-circular groove 16 of the first connecting part 10 with the second semi-circular groove 17 of the annular clip 11. Then, the adjusting bolt 15 is passed through the first threaded hole 13 and the second threaded hole 14. By rotating the adjusting bolt 15, the opening 12 is closed, causing the first semi-circular groove 16 and the second semi-circular groove 17 to tightly interlock and form a fixing hole, thereby firmly fixing the male buckle 7 to the various structures of the bed. Figure 2 As shown. Align the connecting hole 25 on the safety cover 9 with the first engaging part 18 of the male buckle 7 and insert it, so that the protrusion at the end of the first engaging part 18 precisely engages into the groove of the second engaging part 19 of the female buckle 8. At the same time, the limiting plates 20 at the upper and lower ends of the first engaging part 18 and the fixing parts 21 on both sides of the second engaging part 19 cooperate with each other to clamp the safety cover 9, ensuring that the safety cover 9 is reliably fixed in both the horizontal and vertical directions. In addition, the magnetic strip 24 at the bottom of the safety cover 9 magnetically adheres to the edge of the bed, forming a side and bottom fixation, which not only prevents the safety cover 9 from rolling upward or shifting to the side due to patient movement, but also effectively blocks airflow from entering from the bottom, enhancing the windproof effect. In case of emergency rescue, medical staff can directly pull the connecting rope 23 connected to the connecting ring 22 of the female buckle 8, and use the pulling force to separate the second engaging part 19 of the female buckle 8 from the first engaging part 18 of the male buckle 7, so that the protrusion comes out of the groove and quickly releases the engagement between the safety cover 9 and the bed. At the same time, the magnetic strip 24 can be easily disconnected from the bed edge, thus enabling the rapid removal of the safety cover 9, saving valuable time for emergency treatment and ensuring timely rescue of the patient.

[0024] In summary, this utility model can achieve non-restrained physical isolation, and has the advantages of good comfort, windproof effect and easy disassembly.
