Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an integrated hospital bed for use in emergency resuscitation rooms. Background Technology

[0002] Emergency room beds are one of the core pieces of equipment in the entire emergency medical system. They are far more than just a bed to lie on; they are highly integrated, powerful, and mobile rescue platforms or treatment units.

[0003] For example, the patent application number published on the China Patent Network is 202010301926.X, and the patent name is: a hospital bed for emergency department that is easy to get on and off an ambulance. It includes: a support frame, with a cushioning pad installed on the top of the support frame; a bed board, with a bed board installed on the top of the cushioning pad; a cushioning frame, with cushioning frames installed on both sides of the bottom length direction of the support frame; and brakeable support wheels, with brakeable support wheels slidably installed on the bottom of the cushioning frame. The folding support assembly makes it easy for the hospital bed to be moved into or out of the ambulance, improving the efficiency of rescue. Furthermore, the folding bed rail assembly allows the movable bed rails to be quickly opened or fixed.

[0004] However, the existing hospital beds have a relatively simple adjustment method, mainly relying on multiple independent mechanical structures to achieve angle adjustments such as back lifting and leg flexion. This results in a complex internal structure and poor coordination, often leading to stiff and asynchronous movements when performing complex position adjustments, which affects patient comfort. Meanwhile, the adjustment of bedside safety rails is usually completely separate from the bed posture control system, with no linkage between the two. This isolated design poses significant safety hazards, relying entirely on the manual operation and judgment of nursing staff. This can easily lead to the risk of patients falling when the bed is tilted or raised due to negligence, or causing them to get stuck when the rails are not lowered. In addition, the operation method often relies on multiple independently rotating control terminals, which has a high learning cost and is not intuitive. This has obvious limitations in improving nursing efficiency and patient autonomy. These shortcomings together restrict the further development of hospital beds in terms of safety and overall nursing experience.

[0005] Therefore, it is necessary to redesign and modify the integrated hospital bed used in the emergency resuscitation room. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention aims to provide an integrated hospital bed for emergency resuscitation rooms, which has the advantage of being easy to flexibly and quickly adjust multiple angles of the bed.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated hospital bed for an emergency resuscitation room, comprising a bed frame, characterized in that: the bed frame is provided with multiple independently movable support beams and synchronously retractable armrests; the bed frame is provided with a transmission clutch system, which is drivenly connected to the support beams and the armrests respectively; the transmission clutch system has a single operating end, through which the multiple support beams can be selectively driven to adjust independently, and the armrests can be retracted and extended simultaneously while the support beams are being driven.

[0008] As a preferred embodiment of the present invention, the multi-segment support beam includes a middle section beam fixedly mounted on the bed frame, with a front section beam hinged to one side of the middle section beam and a rear section beam hinged to the other side, and the transmission clutch system capable of independently driving the front section beam and the rear section beam to rise and fall.

[0009] As a preferred embodiment of the present invention, the transmission clutch system includes a support structure, a transmission structure, and a clutch structure. The support structure is disposed on the bed frame and is used to support the front crossbeam and the rear crossbeam. The transmission structure is connected to the support structure and is used to drive the support structure to lift and lower. The clutch structure is used to switch the power transmission path of the transmission structure to achieve selective driving of the front crossbeam and the rear crossbeam.

[0010] As a preferred embodiment of the present invention, the support structure includes a connecting plate and a support roller. The connecting plate is connected to the transmission structure, and the support roller is rotatably mounted on the connecting plate. The support roller contacts the bottom of the front crossbeam and the rear crossbeam. When the connecting plate is raised or lowered, it can drive the support roller to rise or fall synchronously and push the corresponding support crossbeam.

[0011] In a preferred embodiment of the present invention, the transmission structure includes a bidirectional screw, a threaded sleeve, a rocker arm, and a drive assembly. The bidirectional screw is rotatably mounted on the bed frame. There are two threaded sleeves, which are threaded to both ends of the bidirectional screw. There are two rocker arms, one end of which is movably connected to the corresponding threaded sleeve, and the other end of which is movably connected to the connecting plate. The drive assembly is connected between the single operating end and the bidirectional screw, and is used to transmit the power of the single operating end to the bidirectional screw.

[0012] In a preferred embodiment of the present invention, the drive assembly includes a worm gear, a worm, a limiting rod, a first inclined cone wheel, and a second inclined cone wheel. The worm gear is connected to the bidirectional screw, and the worm meshes with the worm gear. The limiting rod is rotatably mounted on the bed frame. The first inclined cone wheel is coaxially fixed to the limiting rod with the worm. The second inclined cone wheel is connected to the single operating end and can slide along the axial direction of the limiting rod. By sliding, it can selectively mesh with the first inclined cone wheels on both sides of the middle crossbeam.

[0013] In a preferred embodiment of the present invention, the clutch structure includes a sliding frame and a transmission rod. The sliding frame is sleeved on the outside of the second inclined cone wheel and slidably mounted on the limiting rod. The surface of the limiting rod has a plurality of positioning holes. The transmission rod is installed inside the second inclined cone wheel and is keyed to it. The transmission rod can slide back and forth and can drive the second inclined cone wheel to rotate synchronously when rotating. The front end of the transmission rod passes through the front side of the sliding frame and is connected to the single operating end. The rear end of the transmission rod passes through the second inclined cone wheel and the sliding frame and extends into the interior of the positioning holes. After being inserted, the transmission rod can limit the sliding state of the sliding frame.

[0014] In a preferred embodiment of the present invention, several cranks are rotatably connected to both sides of the bed frame. The end of each crank away from the bed frame is rotatably connected to a limiting armrest. A drive rod is rotatably connected to the width of the bed frame. Both ends of the drive rod are fixedly connected to driven wheels located inside the bed frame. A push rod is fixed to the end face of each driven wheel. When the driven wheel rotates, the push rod can press the crank to make it swing, thereby causing the limiting armrest to rise and fall. The sliding frame is provided with a control structure for driving the driven wheel to rotate.

[0015] As a preferred embodiment of the present invention, the control structure includes a drive wheel fixed to the transmission rod. The drive wheel is located on the front side of the sliding frame. The drive wheel can slide back and forth with the transmission rod. When the axis of the drive wheel corresponds to that of the driven wheel, the drive wheel that slides forward with the transmission rod can be aligned with the driven wheel and enter a meshing state, thereby driving the driven wheel to rotate.

[0016] In a preferred embodiment of the present invention, the drive rod is fitted with a force-bearing plate located in front of the driven wheel. The force-bearing plate is keyed to the drive rod and can move axially along the drive rod. The bottom end of the force-bearing plate extends to the bottom of the driven wheel. A compression spring fitted on the surface of the drive rod is fixedly connected to the front side of the force-bearing plate. The front end of the compression spring is fixedly connected to the surface of the bed frame. A locking pin is fixedly provided on one side of the force-bearing plate. One end of the locking pin can extend into the interior of the driven wheel and engage with it. When the drive wheel slides forward with the drive rod, the drive wheel can squeeze the force-bearing plate to compress the compression spring, and the locking pin disengages from the driven wheel. When the drive wheel resets, the compression spring releases its elastic force, causing the locking pin to re-engage into the interior of the driven wheel, thereby completing the limiting of the driven wheel.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention divides the bed into three support sections and drives them with a centralized transmission clutch system, achieving the effect of integrating back and leg lifting and bed side limit adjustment functions into a compact system. It solves the problems of internal complexity, poor coordination, stiff and asynchronous movements caused by traditional multiple independent mechanical structures, providing patients with more comfortable composite position adjustment possibilities, while greatly simplifying the operation process of medical staff and meeting the high efficiency requirements of emergency rescue.

[0018] 2. By setting up a support structure, the present invention uses a liftable connecting plate to drive the support roller to directly contact and push the bottom of the front and rear crossbeams, thereby achieving the function of smoothly and steadily raising or lowering the bed board in sections by means of rolling contact, avoiding the jamming and noise that may be caused by rigid pushing.

[0019] 3. By setting up a transmission structure, the present invention uses a bidirectional screw to drive the movement of the screw sleeves on both sides, and converts the horizontal movement into the vertical lifting and lowering of the connecting plate through a swing arm. This achieves the effect of using a single rotary input to precisely control the synchronous and equal lifting and lowering of the support points on both sides, ensuring the stability of the bed section during the adjustment process and solving the problem of stiff compound movements.

[0020] 4. By setting up a drive assembly, this invention utilizes a transmission chain consisting of a worm, a worm wheel, and a bevel wheel, and switches the drive target through a sliding frame. This achieves the function of selectively driving the left or right transmission structure through a single operating end, realizing the control of multiple degrees of freedom adjustment by a single power source, simplifying operation and reducing learning costs.

[0021] 5. This invention, by setting up a clutch structure and using a limiting rod to provide a sliding track for the sliding frame, and by sleeved the worm gear and the first inclined conical wheel on the limiting rod, achieves precise positioning of the core components of the drive assembly and a smooth and stable sliding switching process, ensuring the reliability of power transmission path switching. Furthermore, by further limiting the clutch structure and utilizing the sliding transmission rod and its rear end's insertion into the positioning hole, the invention achieves the function of immediately mechanically locking the position of the sliding frame after selecting the drive target, preventing power disengagement due to accidental sliding of the sliding frame during bed adjustment, and ensuring operational safety.

[0022] 6. By setting up a control structure, the present invention connects the transmission rod used to drive the bed lifting and lowering with the driven wheel used to control the handrail through a meshable driving wheel. This achieves the effect of additionally transmitting power to the handrail control mechanism when selecting and driving the bed adjustment, providing a connection for realizing the forced mechanical drive of the handrail state.

[0023] 7. This invention, through the design of a locking pin, a force-bearing plate, and a compression spring structure, achieves the effect of automatically releasing the lock on the drive rod before the driving wheel is ready to engage with the driven wheel, and automatically relocking it after the linkage is completed. This solves the problem of the guardrail mechanism potentially swinging freely during the linkage process and ensures that the guardrail position is firmly fixed in the non-adjustable state, eliminating the safety hazard of guardrail failure due to accidental contact.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 9 As shown, this embodiment provides an integrated hospital bed for an emergency resuscitation room, including a bed frame 1. The top of the bed frame 1 is provided with independently movable multi-segment support beams and retractable limiting handrails 6. The bed frame 1 integrates a transmission clutch system, which is driven and connected to the support beams and the limiting handrails 6 respectively. The transmission clutch system has a single operating end 24 (a wheel in this embodiment). Medical staff can selectively drive the multi-segment support beams to adjust independently by rotating and pushing or pulling the single operating end 24, and can simultaneously drive the limiting handrails 6 to retract and extend while driving the support beams, thereby realizing integrated control of the patient's complex position.

[0028] Specifically, the multi-segment support beam includes a middle section beam 2 fixedly positioned at the top center of the bed frame 1. The middle section beam 2 is bolted to the bed frame 1 to ensure stability. A front section beam 3 is hinged to the left side of the middle section beam 2 via a pin; the front section beam 3 supports the patient's upper body. A rear section beam 4 is hinged to the right side of the middle section beam 2 via a pin; the rear section beam 4 supports the patient's legs. Both the front section beam 3 and the rear section beam 4 can rotate around their hinge points with the middle section beam 2, allowing for height adjustment. The middle section beam 2 remains fixed, serving as the reference point for the entire support beam. A bed board 5 is laid on top of all three sections, forming a movable support surface.

[0029] The transmission clutch system includes a support structure 8, a transmission structure 7, and a clutch structure 16. The support structure 8 is located on both sides inside the bed frame 1. The support structure 8 includes a connecting plate 9. A vertical plate 10 at the top of the connecting plate 9 is movably connected to a support roller 11 via a pin. The outer surface of the support roller 11 contacts the bottom of the front crossbeam 3 and the rear crossbeam 4, respectively. Raising or lowering the connecting plate 9 can drive the support roller 11 to push or release the corresponding bed section, thus achieving angle adjustment.

[0030] The transmission structure 7 includes connecting frames 12 fixed to both sides of the bottom of the bed frame 1. A bidirectional screw 13 is movably connected to the connecting frames 12 via bearings. The threads at both ends of the bidirectional screw 13 have opposite directions, and threaded sleeves 14 are threaded to both sides of its surface. A rocker arm 15 is movably connected to both sides of the threaded sleeves 14 via pins. The other end of the rocker arm 15 is movably connected to the connecting plate 9. When the bidirectional screw 13 rotates, it drives the threaded sleeves 14 to move towards or away from each other, thereby converting the horizontal movement into the vertical lifting and lowering movement of the connecting plate 9 via the rocker arm 15, thus achieving precise lifting or lowering of the support roller 11.

[0031] To selectively drive the left or right transmission structure 7 using a single power source, the bed is equipped with a drive assembly 17. The drive assembly 17, in conjunction with the clutch structure 16, enables control of multi-degree-of-freedom adjustment from a single power source, as well as a mechanical locking function. The drive assembly 17 includes a worm gear 18 fixed to the front end of a bidirectional screw 13, and a worm 19 located on top of and meshing with the worm gear 18. A first inclined cone wheel 20 is fixedly connected to the inner side of the worm 19. The clutch structure 16 includes a bracket 25 fixed to the bottom of the bed frame 1. A limit rod 26 and a guide rod 27 are fixed to the inner side of the bracket 25. The worm 19 and the first inclined cone wheel 20 are sleeved on the surface of the limit rod 26 and movably connected to it via bearings. A sliding frame 21 is slidably sleeved on the surfaces of the guide rod 27 and the limit rod 26. A second inclined cone wheel 22, which meshes with the first inclined cone wheel 20, is movably connected inside the frame via bearings. A transmission rod 23, which can slide back and forth, is installed inside the second inclined cone wheel 22. A single operating end 24 is fixed to the front end of the transmission rod 23. The sliding frame 21 allows the second conical wheel 22 to mesh with the first conical wheel 20 on either the left or right side. Power is then transmitted via the conical wheel pair, worm gear 19, and worm wheel 18 to the selected bidirectional screw 13 by rotating the same single operating end 24. The rear end of the transmission rod 23 can be inserted into positioning holes 39 at different positions on the surface of the limiting rod 26 to lock the sliding position of the sliding frame 21 and prevent accidental disengagement during operation.

[0032] To provide lateral protection, limit handrails 6 are installed on both sides of the top of the bed. Support plates 28 are fixed to both sides of the top of the bed frame 1. Cranks 29 are movably connected to the inner side of the support plates 28 via pins. The other end of the cranks 29 is movably connected to the limit handrails 6, forming a flipping mechanism for the guardrails. A drive rod 30 is movably connected inside the bed frame 1 via bearings. Driven wheels 31 are fixed to both ends of the drive rod 30, and push rods 32 are fixed to the outer side of the driven wheels 31. When the drive rod 30 rotates, it drives the push rods 32 to rotate, thereby squeezing or releasing the cranks 29, achieving a unified and synchronous flipping or retraction of all the limit handrails 6 on both sides.

[0033] To achieve the power linkage between bed adjustment and guardrail operation, a control structure 33 is provided on the transmission rod 23. A drive wheel 34, which slides back and forth with the transmission rod 23, is fixed to its surface. When the transmission rod 23 is in a clutch-engaged state, the drive wheel 34 moves accordingly. A force plate 35, located in front of the driven wheel 31, is keyed to the surface of the drive rod 30. The front of the force plate 35 is connected to the bed frame 1 via a compression spring 36, and a side plate 37 with a locking pin 38 is fixed to one side. In its natural state, the locking pin 38 is inserted into the driven wheel 31 under the action of the compression spring 36, locking it. When the drive wheel 34 slides forward with the transmission rod 23 to align with the axis of the driven wheel 31, it first presses against the force plate 35, compresses the compression spring 36, and pulls the locking pin 38 out of the driven wheel 31, releasing the lock. At this point, if the frame 21 continues to slide forward, the drive wheel 34 and the driven wheel 31 can engage. At this time, rotating the transmission rod 23 will transmit power to the driven wheel 31 through the driving wheel 34, thereby driving the drive rod 30 and the push rod 32 to control the movement of the limit handrail. After adjustment, the driving wheel 34 will disengage from the transmission rod 23, the force plate 35 will reset under the action of the compression spring 36, and the locking pin 38 will re-insert into the driven wheel 31 to lock it.

[0034] Working principle: When adjusting the bed posture, the operator first slides the frame 21 horizontally, engaging the second inclined cone wheel 22 with the first inclined cone wheel 20 on the target side (driving the back or leg section), and then inserts the rear end of the transmission rod 23 into the corresponding positioning hole 39 to lock it in place. Subsequently, rotating the single operating end 24 at the front of the transmission rod 23 transmits power sequentially through the second inclined cone wheel 22, the first inclined cone wheel 20, the worm gear 19, and the worm wheel 18 to the bidirectional screw 13 on the selected side. The rotation of the bidirectional screw 13 drives the movement of the screw sleeves 14 on both sides, which in turn pushes the connecting plate 9 and the support roller 11 vertically up and down via the swing arm 15, thereby smoothly lifting or lowering the corresponding front or rear crossbeam 3 or crossbeam 4, achieving positional adjustments such as raising the patient's back or flexing their legs. The worm gear mechanism ensures that the adjustment angle is self-locking. When the guardrail needs to be adjusted synchronously, during the clutch switching process of the sliding transmission rod 23, the driving wheel 34 moves forward, pressing the force plate 35 to pull the locking pin 38 out of the driven wheel 31, releasing the lock on the guardrail drive shaft. After the driving wheel 34 and the driven wheel 31 are aligned and engaged, the single operating end 24 continues to rotate. While adjusting the drive bed section, the power is also transmitted to the driven wheel 31 through the driving wheel 34, causing the drive rod 30 to rotate. The push rods 32 at both ends of the drive rod 30 rotate accordingly, pushing or releasing all the cranks 29, thereby automatically and synchronously controlling the limit handrails 6 on both sides to flip up to form protection or retract. After the action is completed, the transmission rod 23 and the driving wheel 34 reset, and the locking pin 38 automatically springs back under the action of the compression spring 36, re-inserting into the driven wheel 31 to lock it, preventing the guardrail from swinging accidentally.

[0035] This invention integrates the independent adjustment of multiple bed sections and the automatic linkage function of safety railings through a highly integrated mechanical transmission and clutch system, realizing composite position adjustment controlled by a single operation point (single operation end 24), which greatly simplifies the operation process and improves efficiency and patient safety in emergency rescue scenarios.

When the driving wheel (34) slides forward with the transmission rod (23), the driving wheel (34) can squeeze the force plate (35) to compress the compression spring (36), and the locking pin (38) disengages from the driven wheel (31). When the driving wheel (34) resets, the compression spring (36) releases its elastic force to allow the locking pin (38) to re-engage into the interior of the driven wheel (31), thus completing the limiting of the driven wheel (31).
