Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a bed that facilitates turning over. Background Technology

[0002] Hospital beds are an indispensable basic diagnostic and nursing facility in the modern medical system. Their rational design and complete functionality directly affect the patient's treatment experience, rehabilitation process, and the quality of clinical nursing. However, the traditional general hospital beds widely used in clinical practice currently have many technical defects and application limitations that urgently need to be addressed when performing nursing procedures on patients who are unable to turn over independently.

[0003] First, traditional hospital beds lack specialized mechanical structures to assist with turning over. For patients unable to turn over independently due to spinal cord injury, coma, or postoperative immobilization, position changes rely entirely on manual intervention. This is especially true for heavier patients, where a single medical staff member cannot perform the turning action independently, typically requiring 2-3 staff members working together. This not only significantly increases the daily workload of medical staff and reduces the overall efficiency of nursing care, but more importantly, inconsistent force application or improper movements during multi-person operation can easily lead to secondary injuries to the patient during turning, severely impacting their treatment and rehabilitation.

[0004] Secondly, frequent manual turning operations can also pose occupational injury risks to medical staff. Clinical data shows that long-term repetitive bending, lifting, and twisting turning operations are one of the main causes of musculoskeletal system injuries in medical staff, with common injuries including lumbar muscle strain, lumbar disc herniation, and chronic shoulder joint injuries.

[0005] In conclusion, the goal is to develop a new type of hospital bed that can assist in turning patients over, reduce the workload and occupational risks for medical staff, and ensure patient safety. Summary of the Invention

[0006] The present invention aims to provide a bed that facilitates turning over, in order to solve the problem that existing hospital beds are inconvenient for patients to turn over.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A bed designed for easy turning over includes a bed frame, which includes a bed board. Two through holes are symmetrically arranged on both sides of the bed board, centered on its vertical center line. A lifting platform is installed within each through hole, its size matching the through hole to fill it. A lifting cylinder is connected to the bottom of the lifting platform. A turning switch is installed on the bed frame to control the opening and closing of the lifting cylinder. A pad is provided on the bed board, with creases recessed on the pad corresponding to the inner edges of the two through holes. Anti-slip bars are provided on the sides of the bed board, and flexible protective covers are fitted onto the anti-slip bars.

[0008] Preferably, as an improvement, a first pressure sensor is installed inside the crease recess, the first pressure sensor is electrically connected to a controller, the controller is electrically connected to an alarm, and a trigger block that can contact the first pressure sensor is provided on the side wall outside the crease recess.

[0009] Preferably, as an improvement, the first pressure sensor is electrically connected to the turning switch, and the first pressure sensor starts working after the turning switch is activated.

[0010] Preferably, as an improvement, the first pressure sensor is located at one end of the pad at the foot of the bed.

[0011] Preferably, as an improvement, the anti-slip guardrail is detachably mounted on the bed board.

[0012] Preferably, as an improvement, the bed board has mounting holes, the two ends of the anti-slip stop bar are slidably connected to the mounting holes, and the anti-slip stop bar is provided with external threads.

[0013] Preferably, as an improvement, the protective cover is an airbag, a rigid insertion tube is connected to the anti-slip bar, the bed board has an insertion hole for sliding connection with the insertion tube, a connector for docking with the insertion tube is provided in the insertion hole, a sealing ring is provided on the inner wall of the connector, an air pump is installed in the bed board, the connector is connected to the air pump, an air tube is provided in the anti-slip bar, one end of the air tube is connected to the insertion tube, the other end of the air tube is connected to the airbag, a second pressure sensor is provided at the bottom of the airbag, the second pressure sensor is electrically connected to the controller, and the controller is electrically connected to the air pump.

[0014] Preferably, as an improvement, a push-button inflation switch is provided at the mounting holes at the bottom of the bed board.

[0015] Preferably, as an improvement, there are multiple push cylinders, and the multiple push cylinders are evenly connected to the push platform.

[0016] Preferably, as an improvement, guardrails are provided on both sides of the bed board when it rotates.

[0017] The principles and beneficial effects of this solution are as follows: 1. A pusher cylinder drives a pusher platform to extend from the through-hole, pushing the padding upwards. This pushes the patient's body to one side, causing the padding to fold inwards along the creases towards the opposite side, thus completing the patient's lateral roll. Once the desired position is achieved, medical staff can use pillows, cushions, or other tools to stabilize the patient in a lateral position, assisting in turning the patient from a supine to a lateral position. This method eliminates the need for medical staff to manually move the patient, greatly reducing their workload, especially for heavier patients. It also improves the efficiency of turning and avoids the occupational risks and secondary injuries to the patient caused by frequent manual turning.

[0018] 2. The push table is driven by multiple push cylinders that are evenly connected to it, which can make the force on each part of the push table balanced. At the same time, the multiple push cylinders are controlled by the turning switch, which can make the multiple push cylinders move synchronously, so that the lifting and lowering rate of each part of the push table is consistent. This allows the patient to be turned along the body axis and avoids secondary injuries caused by the twisting of the patient's body due to inconsistent push force. It is especially suitable for patients with spinal injuries and other conditions that require turning along the body axis.

[0019] 3. When not turning over, the push-up platform is flush with the bed board, filling the holes to form a complete flat surface. In addition, the padding on the board ensures the patient's comfort when lying flat. This allows the system to be used as a normal hospital bed when not turning over. At the same time, the padding covers the gap between the push-up platform and the holes, effectively preventing impurities from accumulating in the gap and affecting the smoothness of the push-up platform.

[0020] 4. A first pressure sensor is installed in the concave crease of the pad, and a trigger block is installed on the outer wall of the concave crease to trigger the first pressure sensor. When the rotation angle is too large, the trigger block will squeeze the first pressure sensor, and the first pressure sensor will send a signal to the alarm to alert medical staff to handle the situation. This can effectively avoid problems such as patient instability and arm compression caused by excessive rotation angle.

[0021] 5. The first pressure sensor is also controlled by the turning switch, so that it only activates when the patient turns over, effectively preventing accidental triggering when the patient is not turning over. Additionally, the first pressure sensor is located at the foot of the bed, which also prevents pressure from the patient's body when not in use, effectively extending its lifespan.

[0022] 6. The sides of the bed board are equipped with anti-slip guards, which provide reliable protection during assisted turning, preventing accidental slippage due to pushing force and ensuring effective turning. The guards are covered with a flexible protective sleeve, which has good cushioning properties, limiting movement while avoiding discomfort or pressure injuries from hard contact.

[0023] 7. Insert the anti-slip bar into the mounting hole and fix it by tightening the nut onto the anti-slip bar. This method allows for the detachable connection of the anti-slip bar, which not only makes it easy to replace the anti-slip bar, but also allows for adjustment of the anti-slip bar's position and height by tightening the nuts onto the anti-slip bar at the mounting holes on both the top and bottom of the bed board, thus adapting to the anti-slip obstruction when patients with different degrees of obesity turn over.

[0024] 8. To increase the contact area for anti-slip protection and improve its effectiveness, the bottom of the protective cover on the anti-slip barrier should ideally contact the padding on the bed board after the barrier is raised. However, replacing the protective cover with one of different thicknesses for each adjustment undoubtedly increases the workload of medical staff. To solve this problem, this solution uses an airbag structure for the protective cover. By inflating the airbag, its thickness is changed to fit the anti-slip barrier at different heights, ensuring the cover abuts against the padding and increasing the contact area for anti-slip protection.

[0025] 9. Furthermore, an insertion tube is added to the anti-slip guardrail, and an insertion hole is added to the bed board. When the anti-slip guardrail is installed into the installation hole, the insertion tube naturally inserts into the insertion hole and connects with the connector in the insertion hole. When the nut at the bottom of the bed board is locked onto the anti-slip guardrail, the inflation switch of the bed board can be triggered, thereby automatically starting the air pump in the bed board and automatically inflating the airbag, eliminating the need for manual inflation and reducing the workload of manual labor. Inflating while the anti-slip guardrail is being installed can also improve the efficiency of device preparation, thereby improving the efficiency of work. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the embodiments. Example 1 like Figure 1 and Figure 2 As shown, a bed that facilitates turning over includes a bed frame, which includes a bed board 10 for lying down. Support legs 101 are fixed to the bottom of both ends of the bed board 10. A support rod 102 is connected between two support legs 101 on the same side. Universal wheels 103 are installed on both sides of the bottom of the support legs 101. The universal wheels 103 are of the DW series and have a built-in braking structure. The universal wheels 103 facilitate the flexible movement of the entire bed frame.

[0036] A head baffle 104 is fixedly installed at the head position of the bed board 10, and a tail baffle 105 is fixedly installed at the leg position of the bed board 10. Both the surface of the head baffle 104 and the surface of the tail baffle 105 are provided with perforated holes 106 that penetrate through them. The head baffle 104 and the tail baffle 105 can provide safety protection for the head and tail areas of the patient.

[0037] Both sides of the bed board 10 are equipped with rotatable guardrails, combined with Figure 4 As shown, the rotating mechanism of the guardrail is specifically designed as follows: Two symmetrically arranged bearings 30 are distributed on both sides of the bed board 10. A common shaft 31 runs through the interior of the two bearings 30 along one side. The surface of the shaft 31 is interference-fitted with the inner ring wall of the bearing 30. A sleeve 32 is fixedly fitted onto the surface of the shaft 31, allowing the shaft 31 to rotate based on the bearing 30. The shaft 31 synchronously drives the sleeve 32 to rotate. Several equidistant protective rods 33 are fixedly distributed on the outer ring wall of the sleeve 32. A common handrail 34 is installed at the upper end of each protective rod 33. The protective rods 33 provide fall protection for both sides of the bed board 10, and the handrail 34 facilitates gripping by the patient's hands. Combined with… Figure 6As shown, connecting frames 301 are fixedly installed on both sides of the bed board 10 at the head position. A pin sleeve 302 is fixedly fixed horizontally through the connecting frame 301. A pin 303 is slidably sleeved inside the pin sleeve 302. A spring 304 is wound around the surface of the pin 303. The two ends of the spring 304 are fixedly installed with the end of the pin 303 and the end face of the pin sleeve 302, respectively. A pin seat 305 is fixedly sleeved on the sleeve 32. The pin 303 can slide and connect with the pin seat 305. The spring 304 can ensure the stability of the extension and retraction of the pin 303. The pin 303 has a hand-pulled structure, which is simple and quick to operate. After the pin 303 is separated from the pin seat 305, the guard rod 33 and the handrail 34 can rotate downwards to avoid obstruction when moving the patient. When the guard rod 33 and the handrail 34 are rotated to the vertical position, the sleeve 32 can be fixed in position by inserting the pin 303 into the pin seat 305.

[0038] Combination Figure 4 and Figure 2 As shown, the bed board 10 has two symmetrical through holes 11 on both sides of its vertical center line. A push platform 12 is installed within each through hole 11. Several push cylinders are fixedly installed under the bed board 10 via a bracket. These cylinders are evenly distributed along the length of the push platform 12. The push platform 12 slides through the through holes 11. When not turning over, the push platform 12 fills the through holes 11, and its top surface is flush with the surface of the bed board 10, forming a complete flat surface for the patient to lie on. A push switch is installed on the bed, which can be installed in any convenient location for medical staff to operate. Multiple push cylinders are electrically connected to the push switch, which controls the unified action of the cylinders.

[0039] A padding 14 covers the bed board 10. Both ends of the padding 14 are fixed to the surface of the bed board 10 by fastening bolts 15. The padding 14 has recessed creases 16 on the inner edges of the two through holes 11. When turning over is required, the pusher 12 pushes upwards, causing one side of the padding 14 to flip. This side of the padding 14 flips along the recessed creases 16, increasing the contact area with the body and thus facilitating turning. The fastening bolts 15 secure the padding 14 at both ends, ensuring its stable position during use. Figure 7 As shown, a first pressure sensor 3 is installed inside the crease recess 16. The first pressure sensor 3 is a diaphragm type and is electrically connected to a controller, which is a PLC. The controller is also electrically connected to an alarm, which is an audible and visual alarm. A trigger block 2 that can contact the first pressure sensor 3 is installed on the outer sidewall of the crease recess 16. The first pressure sensor 3 is electrically connected to a turning switch, and the first pressure sensor 3 starts working after the turning switch is activated.

[0040] Combination Figure 3 and Figure 5 As shown, anti-slip guardrails 20 are detachably installed on the sides of the bed board 10. The anti-slip guardrails 20 can be installed on the side facing the patient when turning over to prevent slipping and block the patient's movement. Alternatively, anti-slip guardrails 20 can be installed on both sides, eliminating the need for temporary installation during turning. The specific installation method of the anti-slip guardrails 20 is as follows: both ends of the anti-slip guardrails 20 are right-angled bends. A protective sleeve 21, made of silicone, is glued to the surface of the anti-slip guardrails 20. Mounting holes 22 are opened at both ends of the bed board 10, allowing the two ends of the anti-slip guardrails 20 to slide into the mounting holes 22. External threads 23 are machined on the outer walls of both ends of the anti-slip guardrails 20. After the anti-slip guardrails 20 are inserted into the mounting holes 22, a nut 24 can be locked onto the anti-slip guardrails 20 from the bottom of the bed board 10, with the protective sleeve 21 pressing against the pad 14, to secure the anti-slip guardrails 20. Nut 24 can be selected from nuts 24 with knobs 25 fixed on their surfaces so that nuts 24 can be rotated.

[0041] Work style: When a patient needs to turn to one side, pressing the turning switch controls all the push cylinders connected to the same push platform 12 to move synchronously, driving the push platform 12 to rise from its internal hole, pushing the pad 14 and one side of the patient's body. The creases and concave areas 16 on the surface of the pad 14 act as guides during the pushing process, allowing the pad 14 to smoothly turn along the creases and concave areas 16. The rising motion of the push platform 12 generates continuous thrust, helping the patient gradually turn from a supine position to a side-lying position. During the turning process, the pad 14 increases its contact area with the body, making the turning process smoother and more comfortable. At the same time, the fastening bolts 15 fix both ends of the pad 14 to the bed board 10, ensuring that the pad 14 will not shift under force, thus ensuring the effectiveness and safety of the turning. After the turning is completed, pressing the turning switch again causes the turning cylinder 13 to drive the push platform 12 to reset, and medical staff can manually reset the pad 14.

[0042] During the folding process of the pad 14, the trigger block 2 set on the outer wall of the folded recess 16 on the folding side flips along with the pad 14. At the same time as the flipping switch is pressed, the first pressure sensor 3 is activated. When the trigger block 2 contacts the first pressure sensor 3, the first pressure sensor 3 sends a signal to the controller. The controller controls the alarm to remind medical staff that the flipping range is too large and medical staff need to intervene.

[0043] The anti-slip guard bar 20 is mainly used to limit and protect the patient's body during the assisted turning process. The protective cover 21 is wrapped around the surface of the anti-slip guard bar, which plays a buffering and protective role, avoiding discomfort caused by direct contact between the patient's body and the hard guard bar. When the push platform 12 pushes the patient's body to turn over, the anti-slip guard bar prevents the patient from sliding on the bed due to the pushing force by blocking the body on the opposite side, ensuring the effective completion of the turning action.

[0044] Example 2 The difference between this embodiment and embodiment 1 is that the first pressure sensor 3 is located at one end of the pad 14 at the foot of the bed, which can effectively prevent the first pressure sensor 3 from being squeezed by the patient's body and extend the service life of the first pressure sensor 3.

[0045] Example 3 The difference between this embodiment and Embodiment 1 is that, in combination with Figure 8 As shown, the protective sleeve 21 is an airbag, and the anti-slip bar 20 has rigid insertion tubes 4 vertically connected to both ends. The bed board 10 has insertion holes 5 for sliding connection with the insertion tubes 4. A connector 6 for docking with the insertion tubes 4 is installed in the insertion holes 5. A sealing ring is glued and fixed on the inner wall of the connector 6. An air pump is installed in the bed board 10, and the connector 6 is connected to the air pump. An air tube is installed in the anti-slip bar 20. One end of the air tube is connected to the insertion tubes 4, and the other end of the air tube is connected to the airbag. A second pressure sensor is installed at the bottom of the airbag. The second pressure sensor is also a diaphragm pressure sensor. The second pressure sensor is electrically connected to the controller, and the controller is electrically connected to the air pump.

[0046] In this embodiment, when the anti-slip barrier 20 is installed, and both ends of the anti-slip barrier 20 are inserted into the mounting holes 22, the insertion tube 4 on the anti-slip barrier 20 is also inserted into the insertion hole 5, thus automatically connecting with the connector 6 in the insertion hole 5. This embodiment is applicable when the overall position and height of the anti-slip barrier 20 are adjusted. By starting the air pump, the airbag is inflated through the connector 6, insertion tube 4, and air pipe. After the airbag inflates, its bottom contacts the pad 14, which increases the blocking area of ​​the anti-slip barrier 20 and the airbag as a whole on the side, thereby improving the anti-slip blocking effect. When the airbag is inflated to the point where the second pressure sensor abuts against the pad 14, the second pressure sensor sends a signal to the controller, and the controller controls the air pump to automatically stop inflating.

[0047] Example 4 The difference between this embodiment and embodiment 3 is that a push-button inflation switch is installed at the mounting hole 22 at the bottom of the bed board 10. In this embodiment, when the nut 24 at the mounting hole 22 at the bottom of the bed board 10 is tightened onto the anti-slip bar 20, the nut 24 presses against the inflation switch at the mounting hole 22, automatically starting the air pump to inflate the airbag without manual operation, thus improving inflation efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
