Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to a detachable medical bed. Background Technology
[0002] In the field of medical care, hospital beds serve as the core carriers for patient treatment and rehabilitation, and their functional design directly affects the efficiency of clinical procedures and the patient's comfort experience. Currently, most medical beds on the market adopt an integrated frame structure, including components such as bed frame, bed board, lifting mechanism, and guardrails. While this can meet basic nursing needs, it exposes significant limitations in patient transport scenarios.
[0003] When patients need to be transferred between different beds (e.g., from an emergency room bed to an ICU bed, or from an operating table to a ward bed), traditional methods rely on manual labor or auxiliary tools such as transfer boards and hoisting equipment. These methods have the following drawbacks: High reliance on human effort: Multiple medical staff need to work together to lift the patient, which is time-consuming and laborious, and carries the risk of secondary injury due to coordination errors; Poor patient experience: Repeated moving can exacerbate patient pain, especially for patients with fractures, post-operative patients, or those in critical condition, and may lead to complications.
[0004] Although some improvement solutions have proposed modular bed designs (such as removable guardrails or split mattresses), the core bed frame is still an indivisible whole structure, which still suffers from high dependence on human intervention and poor patient experience.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0033] Please refer to Figures 1 to 10A detachable medical bed includes multiple guide base plates 100, guide wheels 200, and a guide docking mechanism 300. The bottom guide base plate 100 is fixedly installed, and adjacent guide base plates 100 can slide relative to each other. For example, two guide base plates 100 are provided, with the bottom guide base plate 100 fixed and the upper guide base plate 100 sliding along a first direction. The sliding method can be friction sliding, rolling sliding, etc. Alternatively, three guide base plates 100 are provided, with the bottom guide base plate 100 fixed, the middle guide base plate 100 sliding along a first direction, and the top guide base plate 100 sliding along a second direction. The first and second directions are perpendicular to each other, and the sliding method can be friction sliding, rolling sliding, etc. The function of transferring patients is achieved through the relative sliding between the multiple guide base plates 100. Simultaneously, the guide base plates 100 are relatively thin, made of lightweight alloy materials, and need to meet the support strength required for the patient's body. The guide wheel 200 is disposed below the guide base plate 100. The guide wheel 200 can move on the ground and can be adjusted vertically. The guide base plate 100 is moved by the movement of the guide wheel 200.
[0034] The guiding docking mechanism 300 includes a laser positioning module 310 and a buffer guide post 320. The laser positioning module 310 is disposed on the guide substrate 100 and is used to emit a positioning beam. The laser positioning module 310 is an existing device (laser positioning is a technology that uses a laser beam for precise positioning. Its principle is to emit a laser beam between the measuring object and the sensor, and generate a detectable point or laser stripe on the object. After the sensor receives the reflected laser signal, it calculates the precise position of the object based on the time delay and spatial relationship of the signal. The transmitter can emit a 3×3 intersecting positioning beam with a wavelength of 650nm and a power of <5mW). It can position the transfer bed and the transferred bed 500 so that they are parallel and aligned with each other. At the same time, it keeps the distance between the transfer bed and the transferred bed 500 at a suitable interval, which facilitates docking between the transfer bed and the transferred bed 500, thereby transferring the patient.
[0035] The buffered guide post 320 is disposed on the guide base plate 100, and one end of the buffered guide post 320 is connected to the top guide base plate 100. The buffered guide post 320 can gradually extend to push the top guide base plate 100 to move to one side.
[0036] Specific usage process:
[0037] For patients with fractures, post-operative conditions, or severe illnesses, it is necessary to move the patient from the initial transfer bed 500 to the transfer bed (from the surgical gurney to the detachable medical bed). The detachable medical bed is pushed, and the laser positioning module 310 positions the initial transfer bed 500 (surgical gurney) to a suitable distance and level. The guide plate 100 is adjusted so that its upper surface is slightly higher than the surface of the initial transfer bed 500 (surgical gurney), keeping the detachable medical bed stationary. The buffer guide column 320 is then activated, gradually extending and pushing the guide plates 100 to slide relative to each other, bringing the upper guide plate 100 closer to the initial transfer bed 500 (surgical gurney). The upper guide plate 100 of the trolley is attached to the bed surface of the transfer bed 500 (surgical trolley) and close to the patient. The medical staff only needs to slightly turn the patient's body to move the patient onto the guide plate 100. Then, the guide plate 100 is pushed forward to move the patient's entire body onto the guide plate 100. The buffer guide column 320 retracts, driving the guide plate 100 to retract until the patient is moved from the transfer bed 500 to the transfer bed (from the surgical trolley to the detachable medical bed). During this process, because the detachable medical bed is relatively heavy, even if the guide plate 100 extends and the patient moves onto the guide plate 100, it will not cause the detachable medical bed to shift or tip over. The detachable medical bed significantly reduces reliance on manual labor, requiring only minor movements of the patient by a small number of medical staff. Furthermore, it avoids repeated patient handling, reducing patient pain. Additionally, the laser positioning module 310 enables rapid alignment of the transferred bed 500 with the transfer bed (surgical trolley and detachable medical bed), eliminating cumbersome adjustment and alignment steps and facilitating rapid patient transfer.
[0038] Further description: The guiding docking mechanism 300 includes a control panel, which is electrically connected to the laser positioning module 310 and the buffer guide post 320. The control panel controls the opening and closing of the laser positioning module 310, and simultaneously controls the extension and retraction of the buffer guide post 320. The control panel is an existing device, configured in conjunction with the laser positioning module 310 and the buffer guide post 320.
[0039] Specifically, the guide wheel 200 includes a support rod 210 and a universal swing wheel 220. The support rod 210 is disposed below the guide base plate 100, and the universal swing wheel 220 is disposed at one end of the support rod 210, with the universal swing wheel 220 located on the side away from the guide base plate 100. The universal swing wheel 220 is a conventional wheel body, and the universal swing wheel 220 has a built-in spring damping system, with its surface covered with antibacterial material.
[0040] Further, see Figures 1 to 9 The guide substrate 100 includes a first substrate 110, a second substrate 120, and a third substrate 130. The first substrate 110 is horizontally fixed, and the guide wheel 200 is disposed on the lower end surface of the first substrate 110. The second substrate 120 is placed flat on the upper end surface of the first substrate 110, and the second substrate 120 translates relative to the first substrate 110 in a first direction, such as translating forward or backward. The third substrate 130 is disposed on the upper end surface of the second substrate 120, and the third substrate 130 translates relative to the second substrate 120 in a second direction, such as moving to the left or right. By moving the second substrate 120 and the third substrate 130 in different directions, on the one hand, the laser positioning module 310 can quickly locate the patient during positioning; on the other hand, for limited locations in hospitals where ordinary transfer beds are not easy to move, this detachable medical bed can also be moved to facilitate patient transfer.
[0041] Furthermore, for some severely ill patients, transfer is extremely difficult, requiring them to rest in bed for an extended period before a second transfer can be performed. Therefore, see [link to relevant documentation]. Figures 7 to 9The buffered guide post 320 includes an electric push rod 321 and a push post 322. The electric push rod 321 is disposed on both sides of the second substrate 120, and the push post 322 is disposed on both sides of the third substrate 130. The push post 322 and the electric push rod 321 are hinged to each other. For example, the third substrate 130 can be directly laid on an emergency bed. When a patient needs to be transferred to a monitoring bed, a detachable medical bed is used, but this detachable medical bed does not have the third substrate 130. The detachable medical bed is pushed to one side of the emergency bed and positioned. The buffer guide column 320 is extended. Since the buffer guide column 320 is hinged to the push columns 322 on both sides of the third substrate 130, it is in a separated state at this time. When the buffer guide column 320 extends to the push column 322 and connects with the push column 322, the buffer guide column 320 retracts, thereby retracting the third substrate 130 onto the second substrate 120, allowing the patient to be transferred to the detachable medical bed. The opposite method is used: the third substrate 130 is pushed flat onto the monitoring bed, and the buffer guide column 320 and the push column 322 are separated from each other, so that the third substrate 130 and the patient are left on the monitoring bed at the same time.
[0042] Furthermore, see Figure 9The push column 322 includes a sleeve 3221 and a rotating column 3222. The sleeve 3221 is disposed on both sides of the third base plate 130. The rotating column 3222 is rotatably sleeved in the sleeve 3221 and limited to both sides of the rotating column 3222. One end of the rotating column 3222 is provided with a threaded sleeve 3223. The threaded sleeve 3223 is located on the side close to the electric push rod 321. The protruding end of the electric push rod 321 is provided with a thread and is screwed into the threaded sleeve 3223. The inner diameter of the sleeve 3221 is the same as the outer diameter of the rotating column 3222. After the rotating column 3222 is fitted into the sleeve 3221, it can rotate within the sleeve, but cannot swing significantly within the sleeve 3221. When the third substrate 130 and the second substrate 120 need to be separated, the rotating column 3222 is turned, and the rotating column 3222 rotates within the sleeve 3221. The threaded sleeve 3223 at one end of the rotating column 3222 is disassembled from the thread at one end of the electric push rod 321. When the third substrate 130 and the second substrate 120 need to be installed together, the rotating column 3222 is turned, and the rotating column 3222 rotates inside the sleeve 3221. The threaded sleeve 3223 at one end of the rotating column 3222 engages with the thread at one end of the electric push rod 321. By rotating the rotating column 3222 inside the sleeve 3221, the threaded sleeve 3223 engages with or disengages from the thread, which can quickly realize the matching or separation of the third substrate 130 and the second substrate 120.
[0043] As a preferred option, see Figures 7 to 9 The second substrate 120 has a magnetic guide rail 121 on its upper surface, and the third substrate 130 has a magnetic track groove 131 on its lower surface. The magnetic guide rail 121 and the magnetic track groove 131 are magnetically attracted to each other, and can slide relative to each other. The magnetic guide rail 121 is engaged with the magnetic track groove 131. When the buffer guide post 320 pushes the third substrate 130 forward, the third substrate 130 can move along the magnetic guide rail 121, preventing the third substrate 130 from deviating during the movement.
[0044] Furthermore, a neck pillow 133 is detachably provided on the third base plate 130, which allows the patient to rest their head on the neck pillow 133 and limits the patient's position, preventing the patient from shifting significantly during bed movement.
[0045] As a preferred option, see Figure 5 and Figure 6The guiding docking mechanism 300 further includes a spiral drive assembly 330, which is disposed on the first substrate 110 and connected to the second substrate 120. The spiral drive assembly 330 drives the second substrate 120 to translate along a first direction. The spiral drive assembly 330 is electrically connected to the control panel, controlling its rotation. The spiral drive assembly 330 drives the second substrate 120 to translate in the first direction (forward or backward).
[0046] Specifically, the spiral drive assembly 330 includes a spiral driver 331, a drive motor 332, and a top plate 333. The spiral driver 331 is fixedly mounted on the first substrate 110. The spiral driver 331 is an existing device and will not be described in detail here. The drive motor 332 is mounted on the first substrate 110 and connected to the spiral driver 331. The top plate 333 is disposed on the spiral driver 331, and the second substrate 120 is snapped onto the top plate 333. By activating the drive motor 332, the drive motor 332 drives the spiral driver 331 to rotate. The lead screw inside the spiral driver 331 rotates, causing the second substrate 120 to translate along a first direction.
[0047] Specifically, the top plate 333 and the second substrate 120 can be connected by a screw fixation or by a limiting post snap-fit, in which the second substrate 120 is fixed on the top plate 333.
[0048] Further, see Figure 5 and Figure 6 The first substrate 110 has a limiting slide rail 111 on its upper surface, and the second substrate 120 has a limiting slide groove 122 on its lower surface. The limiting slide rail 111 and the limiting slide groove 122 are engaged with each other, and the limiting slide rail 111 and the limiting slide groove 122 can slide relative to each other. As the second substrate 120 moves along the limiting slide rail 111, the limiting slide rail 111 prevents the second substrate 120 from shifting during the movement.
[0049] In one possible embodiment, see Figure 1 and Figure 10The detachable medical bed further includes a restraint mechanism 400. A concealed groove 132 is formed on the upper surface of the third base plate 130, and the restraint mechanism 400 is disposed within the concealed groove 132. The restraint mechanism 400 is used to restrain the patient's legs, waist, or chest to prevent the patient from swaying during movement of the detachable medical bed, which could lead to wound tearing. When the restraint mechanism 400 is not in use, it is located within the concealed groove 132, preventing it from protruding from the third base plate 130 and increasing the patient's comfort while lying flat on the third base plate 130. When the restraint mechanism 400 is not in use, the concealed groove 132 is in a closed state.
[0050] Specifically, the third base plate 130 is also provided with a slot. After one end of the restraint mechanism 400 extends out, it can be engaged in the slot, similar to a car seat belt.
[0051] For details, see Figure 1 The restraint mechanism 400 includes a housing 410, a winding assembly 420, and a restraint strap 430. The housing 410 is embedded within the concealed groove 132. The winding assembly 420 is disposed within the housing 410 and is rotatable and retractable. The winding assembly 420 is a commonly used winding device. The restraint strap 430 is connected to the winding assembly 420 and is wound around the winding assembly 420. When using the restraint strap 430, the concealed groove 132 is opened, the restraint strap 430 is pulled out, and the restraint strap 430 is wrapped around the patient's legs, waist, or chest. One end of the restraint strap 430 is then engaged in the slot to achieve a fixation effect on the patient.
[0052] Further, see Figure 1 The guiding docking mechanism 300 further includes a hydraulic upper support column 340, which is mounted on the guide wheel 200 and used to lift the guide base plate 100 to move vertically upward. The hydraulic upper support column 340 is electrically connected to the control panel, and the control panel controls the raising or lowering of the hydraulic upper support column 340. The raising or lowering of the hydraulic upper support column 340 enables the laser positioning module 310 to quickly complete the positioning of the bed body, aligning the transferred bed body 500 with the transfer bed body, facilitating the extension of the third base plate 130 onto the transferred bed body 500.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
