Background Technology

[0002] Hospitalized patients face risks such as falls from bed, tube slippage, and limb eversion due to impaired consciousness, limited limb movement, or the need for postoperative immobilization. Bed safety protection devices are important equipment to ensure patient safety and assist in medical care. Their design must take into account both functionality and human needs. Bed rails can limit the range of movement of patients and prevent falls when turning over or becoming agitated. The rails are designed with a grippable structure to help patients sit up or move, reducing the burden on nursing staff.

[0003] Traditional multi-level safety protection devices for hospital beds have a simple structure, usually using fixed guardrails. While this protection measure can effectively protect patients, if the guardrails cannot be opened, it will cause obstacles to emergency rescue and treatment. If the guardrails cannot be opened, they must be completely removed to perform chest compressions, which takes about 2-3 minutes. However, the tolerance limit for cerebral ischemia is only 4-6 minutes. According to statistics, the delay in CPR initiation caused by guardrail obstruction can reduce the patient's survival rate by 15%-20%. Furthermore, fixed guardrails also make daily care difficult for nurses.

[0004] Therefore, there is an urgent need to improve a retractable multi-level safety protection device for hospital beds to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7 As shown in the figure, this embodiment provides an example of a retractable multi-level safety protection device for a hospital bed.

[0027] A retractable multi-level safety protection device for a hospital bed includes a bed body 1 and support legs 2. A bed board 3 is installed on the bed body 1. A retractable protective structure 4 is provided on the bed body 1. The retractable protective structure 4 includes fixed frames 5 fixedly installed on both sides of the bed body 1. A first guardrail 6 is fixedly installed inside the fixed frames 5. A first sliding groove 7 is opened on the first guardrail 6. A second guardrail 8 is movably installed inside the first sliding groove 7. Multiple first sliding rods 9 connected to the first guardrail 6 are fixedly installed on the second guardrail 8. A second sliding groove 10 is opened on the second guardrail 8. A third guardrail 11 is movably installed inside the second sliding groove 10. Multiple second sliding rods 12 connected to the second guardrail 8 are fixedly installed on the third guardrail 11. By setting up the retractable protective structure 4, the traditional fixed protective device on the bed body 1 is changed, so that this protective measure can not only effectively protect the patient, but also will not cause obstacles to emergency rescue and emergency treatment. When the patient is lying on the bed board 3 and needs protection, the second guardrail 8 is pulled first to move from the first guardrail 6. The third guardrail 11 is pulled out from inside the second guardrail 8 after the second guardrail 8 is pulled out to a certain position. After the second guardrail 8 is fully pulled out, it can completely surround the main body of the bed 1. The hollow design of the third guardrail 11, the second guardrail 8 and the first guardrail 6 not only makes the main body of the bed 1 closed, but also does not affect the patient's vision, thus avoiding the patient's feeling of oppression. At the same time, the first sliding rod 9 and the third guardrail 11, together with the first sliding groove 7 and the second sliding groove 10, can reduce the friction when the third guardrail 11 and the second guardrail 8 move, so that the second guardrail 8 and the third guardrail 11 are pulled out more effortlessly. In case of emergency, the third guardrail 11 can be pushed directly into the first guardrail 6 along with the second guardrail 8. The advantage of this structure is that the protective device can be opened quickly, so there is no need to spend time disassembling the protective device as a whole, thus avoiding the decrease in patient survival rate caused by the time spent disassembling the protective device. In addition, the easy-to-open protective device also facilitates the nurses' daily nursing work.

[0028] like Figure 1 and Figure 5 As shown, a connecting frame 13 is fixedly installed on one side of the first guardrail 6. A connecting rod 14 is installed inside the connecting frame 13. A connecting plate 15 is fixedly installed at one end of the connecting rod 14. Multiple first electric telescopic rods 16 connected to the second guardrail 8 are fixedly installed inside the connecting plate 15. A second electric telescopic rod 17 connected to the third guardrail 11 is fixedly installed inside the second guardrail 8. Through the arrangement of the connecting frame 13, connecting rod 14, connecting plate 15, first electric telescopic rods 16 and second electric telescopic rods 17, when multiple first electric telescopic rods 16 are operated simultaneously, they can drive the second guardrail 8 out of the inside of the first guardrail 6 when they extend. Then, when the second electric telescopic rod 17 is activated to extend, it can drive the third guardrail 11 out of the inside of the second guardrail 8. Therefore, it is not necessary for personnel to manually open or close the second guardrail 8 and the third guardrail 11, saving labor and avoiding damage caused by personnel pushing the second guardrail 8 and the third guardrail 11 with excessive force.

[0029] like Figure 5 and Figure 6 As shown, both the connecting frame 13 and the connecting rod 14 have connecting holes 18. A plug rod 19 is movably installed inside the connecting hole 18. A latch 20 is fixedly installed at one end of the plug rod 19, and a toothed ring 21 is fixedly installed at the other end of the plug rod 19. Through the connecting hole 18, the plug rod 19, the latch 20, and the toothed ring 21, after the connecting rod 14 is inserted into the connecting frame 13, the plug rod 19 is inserted into the connecting hole 18. Then, the plug rod 19 is rotated so that the angle of the latch 20 is perpendicular to the angle of the connecting hole 18, and the connecting rod 14 is fixed inside the connecting frame 13. Therefore, the connecting plate 15 can support multiple first electric telescopic rods 16. When the plug rod 19 is rotated so that the angle of the latch 20 is consistent with the angle of the connecting hole 18, the plug rod 19 can be pulled out from the inside of the connecting hole 18, so that the connecting rod 14 can be removed from the connecting frame 13. This makes it convenient for personnel to inspect the first electric telescopic rods 16.

[0030] like Figure 5As shown, a fixing plate 22 is fixedly installed on the first guardrail 6. A third electric telescopic rod 23 is fixedly installed on the top of the fixing plate 22. A fixing post 24 is fixedly installed on the output end of the third electric telescopic rod 23. A connecting sleeve 25 is sleeved on the fixing post 24. A locking tooth 26 that meshes with the toothed ring 21 is fixedly installed on one end of the connecting sleeve 25. With the arrangement of the fixing plate 22, the third electric telescopic rod 23, the fixing post 24, the connecting sleeve 25 and the locking tooth 26, the extension of the third electric telescopic rod 23 can drive the locking tooth 26 to rise. When the locking tooth 26 rises and engages with the toothed ring 21, the locking tooth 26 can limit the insertion rod 19 after it is engaged, thereby preventing the insertion rod 19 from being accidentally knocked out of the connection hole 18. When the third electric telescopic rod 23 retracts and drives the locking tooth 26 to disengage from the toothed ring 21, the insertion rod 19 can be rotated normally.

[0031] like Figure 2 and Figure 3 As shown, the fixed frame 5 and the first guardrail 6, the second guardrail 8 and the third guardrail 11 are all provided with limit holes 27. Limit rods 28 are provided inside the limit holes 27. With the setting of limit holes 27 and limit rods 28, when the second guardrail 8 and the third guardrail 11 are in the unfolded state, multiple limit rods 28 are inserted into the limit holes 27 to fix and limit the first guardrail 6, the second guardrail 8 and the third guardrail 11 respectively, which can improve the stability of the protection of the three. After the multiple limit rods 28 are removed from the limit holes 27, the second guardrail 8 and the third guardrail 11 can be pushed and pulled normally.

[0032] like Figure 5 As shown, the fixed post 24 has multiple mounting holes 29. A spring 30 is fixedly installed inside the mounting hole 29. A retaining ball 31 is fixedly installed at one end of the spring 30. The inner side of the connecting sleeve 25 has multiple retaining holes that cooperate with the retaining ball 31. With the arrangement of the mounting holes 29, spring 30, retaining ball 31 and retaining holes, when the fixed post 24 is inserted into the connecting sleeve 25, the retaining ball 31 can pop out under the elastic action of the spring 30 and engage in the retaining hole on the inner side of the connecting sleeve 25, thereby fixing the fixed post 24 inside the connecting sleeve 25. This allows the retaining tooth 26 to be installed on the third electric telescopic rod 23. When the retaining tooth 26 is pulled, the retaining ball 31 will be squeezed and contracted into the mounting hole 29, so that the connecting sleeve 25 can be removed from the fixed post 24, making it convenient for personnel to disassemble and replace the retaining tooth 26 when it is damaged.

[0033] like Figure 1 and Figure 7As shown, the first sliding rod 9 has multiple placement holes 32. Touch sensors 33 are fixedly installed inside the placement holes 32 and on the top of the first guardrail 6. An information transmission structure 34 is provided at one end of the bed body 1. The information transmission structure 34 is electrically connected to the touch sensors 33. Through the placement holes 32, touch sensors 33 and information transmission structure 34, when a patient with sleepwalking symptoms crawls out of the protective device while sleeping, the touch sensor 33 will sense a certain part of the patient's body, and then the sensing signal will be transmitted to the information transmission structure 34. The information transmission structure 34 will then transmit the information to the duty room, ensuring that the nurse can discover and rush to the scene in time to prevent the patient from having an accident.

[0034] In this embodiment, as Figures 1-7 As shown in the figure, the working process of the retractable multi-level safety protection device for hospital beds provided in this embodiment is as follows:

[0035] When a patient needs protection while lying on the bed board 3, first pull the second guardrail 8 to pull it out from inside the first guardrail 6. After the second guardrail 8 is pulled out to a certain position, pull the third guardrail 11 out from inside the second guardrail 8. After the second guardrail 8 is fully pulled out, it can completely surround the main body of the bed 1. The hollow design of the third guardrail 11, the second guardrail 8 and the first guardrail 6 not only makes the main body of the bed 1 closed, but also does not affect the patient's vision, thus avoiding the patient's feeling of oppression. At the same time, the first sliding rod 9 and the third guardrail 11, together with the first sliding groove 7 and the second sliding groove 10, can reduce the friction when the third guardrail 11 and the second guardrail 8 move, so that the second guardrail 8 and the third guardrail 11 are easier to pull out. In case of emergency, simply push the third guardrail 11 to push it into the first guardrail 6 along with the second guardrail 8.

[0036] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
