Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical bed. Background Technology

[0002] Medical beds typically refer to beds used in medical institutions, primarily for patient rest, treatment, and care. To facilitate patient dining and recreation, medical beds are often equipped with a rotating dining table. The table can be rotated to the desired position when in use and stored away when not in use.

[0003] In related technologies, such as Chinese patent document CN217286361U, a medical bed with a dining table is disclosed, including a bed frame, a dining table, a drive assembly, and a locking assembly. The dining table is rotatably connected to the bed frame. The drive assembly includes components for driving the dining table to rotate, and the locking assembly is used to manually lock the position of the dining table. When needed, the driving component rotates the dining table to the desired position; when not needed, the driving component drives the dining table to the foot of the bed for storage.

[0004] Regarding the aforementioned technologies, food scraps are inevitably left on the dining table after use. When cleaning up these scraps, they can easily fall onto the bed and stain the bedding. Summary of the Invention

[0005] To facilitate the cleaning of food scraps on the dining table and prevent soiling of bedding, this application provides a medical bed.

[0006] The medical bed provided in this application adopts the following technical solution: A medical bed includes a bed frame and a dining table rotatably mounted on the bed frame. The dining table includes support rods rotatably mounted on opposite sides of the bed frame, a support rod located between the two support rods, and a dining board mounted on the support rod. One side of the support rod is rotatably connected to the adjacent support rod, and the other side of the support rod is provided with a locking assembly for fixing or disengaging the support rod relative to or away from the support rod on the side away from its own axis of rotation.

[0007] By adopting the above technical solution, the side of the support rod away from its own rotation axis is separated from the nearby support rod by the locking component. Then, the support rod and the tray are rotated towards the foot of the bed until the tray is moved outside the bed. At this time, food scraps on the tray can be cleaned and easily pushed into the trash can. Since the tray is outside the bed, food scraps will not fall onto the bed and contaminate the bedding when cleaning.

[0008] Preferably, guardrails are provided on opposite sides of the bed frame, and the dining table is located between the guardrails on both sides. The distance from the side of the guardrail away from the head of the bed to the head of the bed is greater than the distance from the support rod to the head of the bed when it is in a vertical state. The support rod is located above the guardrails and the foot of the bed frame. The support rod includes a horizontal section and connecting sections at both ends of the horizontal section. The dining table is set on the horizontal section. The support rod that rotates with the support rod is provided with a threaded section. The connecting section on the side near the threaded section is threadedly engaged with the threaded section. The locking component is set on the connecting section on the side away from the threaded section. The horizontal section is used to abut against the guardrail. When the support rod is in a vertical state, when the connecting section drives the horizontal section and the dining table to rotate toward the foot of the bed, the connecting section that rotates with the threaded section rotates toward the bed frame.

[0009] By adopting the above technical solution, the support rod and the tray are rotated towards the foot of the bed until they extend out of the bed frame. At this time, the connecting section drives the horizontal section and the tray to move downward a certain distance, so that the guardrail abuts against the horizontal section. At this time, the guardrail can provide certain support for the support rod and tray located outside the bed frame, which helps to ensure the structural stability of the support rod and the support rod. At the same time, the horizontal section cannot continue to rotate towards the head of the bed under the abutment of the guardrail, thus limiting the tray.

[0010] Preferably, a mounting cylinder is provided on the support rod near the threaded section, and an opening is provided on the connecting section near the mounting cylinder for the mounting cylinder to move through. A receiving groove communicating with the mounting cylinder is provided on the support rod where the threaded section is located. A press-type disinfectant spray bottle is provided in the receiving groove, and the disinfectant spray bottle extends into the mounting cylinder. A spray nozzle for disinfectant to be sprayed is provided on the side wall of the mounting cylinder. The spray nozzle is oriented away from the bed. A limiting component is provided in the mounting cylinder to restrict the movement of the disinfectant spray bottle relative to the support rod. When the horizontal section abuts against the guardrail, the spray nozzle is located above the dining board.

[0011] By adopting the above technical solution, when the dining board is rotated and moved out of the bed towards the foot of the bed, the connecting section near the disinfectant spray bottle is rotated downward along the corresponding support rod, so that the connecting section exposes the spray nozzle. Until the dining board is moved to the required position, the spray nozzle is aligned with the dining board, and the nozzle of the disinfectant spray bottle is pressed down so that the disinfectant is sprayed from the spray nozzle onto the dining board, which helps to disinfect the dining board and the disinfectant will not be sprayed on the bed.

[0012] Preferably, the limiting component includes a cover plate slidably disposed within the mounting cylinder and a pull member disposed within the mounting cylinder. The cover plate is located on the side of the disinfectant spray bottle away from the bed body, and the sliding direction of the cover plate is parallel to the length direction of the mounting cylinder. The pull member is used to pull the cover plate to abut against the nozzle of the disinfectant spray bottle.

[0013] By adopting the above technical solution, the cover plate abuts against the nozzle of the disinfectant spray bottle under the pull of the pulling component, so that the support rod is not easy to move relative to the support rod during use and storage, and can seal the mounting cylinder, so that the disinfectant in the disinfectant spray bottle is not easy to evaporate.

[0014] Preferably, the pulling member includes a spring for pulling the cover plate to abut against the nozzle of the disinfectant spray bottle. One end of the spring is disposed inside the mounting cylinder, and the other end is disposed on the cover plate. When the spring is in its natural state, the cover plate abuts against the nozzle of the disinfectant spray bottle, and the nozzle of the disinfectant spray bottle is in its natural state.

[0015] Preferably, a connecting block is slidably disposed inside the mounting cylinder, the sliding direction of the connecting block is parallel to the length direction of the mounting cylinder, one end of the spring away from the inner wall of the mounting cylinder is disposed on the connecting block, and an adhesive is disposed between the connecting block and the cover plate, the adhesive being used to fix or detach the connecting block from the cover plate.

[0016] By adopting the above technical solution, the cover plate is moved away from the mounting cylinder, so that the cover plate is separated from the connecting block, which makes it easier to replace the disinfectant spray bottle.

[0017] Preferably, the adhesive includes a first Velcro strip disposed on the connecting block and a second Velcro strip disposed on the cover plate, wherein the first Velcro strip is used to bond with the second Velcro strip.

[0018] Preferably, the inner wall of the receiving groove is provided with an elastic fixing ring, and the disinfectant spray bottle is located inside the fixing ring and abuts against the inner wall of the fixing ring.

[0019] Preferably, the locking assembly includes a locking rod and a connector disposed on the locking rod. The locking rod slides through a connecting section on the side away from the threaded section. The sliding direction of the locking rod is parallel to the length direction of the support rod. A slot for insertion and engagement with the locking rod is provided on the support rod on the side away from the threaded section. The connector is used to fix the locking rod relative to the bottom wall of the slot.

[0020] By adopting the above technical solution, the locking rod is moved away from the support rod, disengaging it from the slot. At this time, the connecting section and the end of the support column are movable, allowing the support rod to be rotated towards the foot of the bed for cleaning the dining board. When cleaning is complete and the dining board needs to be reset, the support rod is rotated towards the foot of the bed to reset it, moving the connecting section away from the threaded section to the top of the corresponding support rod, aligning the locking rod with the slot. Then, the locking rod is moved towards the slot to engage with it. The locking rod is fixed to the bottom wall of the slot by the connector, which helps to ensure the relative fixation of the support rod and the support column.

[0021] Preferably, the connector includes a third hook and loop fastener disposed on the locking lever and a fourth hook and loop fastener disposed on the bottom wall of the slot, wherein the third hook and loop fastener is used to bond and engage with the fourth hook and loop fastener.

[0022] In summary, this application includes the following beneficial technical effects: By locking the support rod to disengage the side away from its own axis of rotation from the nearby support rod, rotate the support rod and the tray towards the foot of the bed until the tray is moved outside the bed. At this point, food scraps on the tray can be cleaned and easily disposed of in the trash can. Since the tray is outside the bed, food scraps will not fall onto the bed and contaminate the bedding during cleaning. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a medical bed. (See also...) Figure 1The medical bed includes a bed body 1 and a dining table 2 rotatably mounted on the bed body 1. The dining table 2 includes support rods 21, support rods 22, and a dining board 23. There are two support rods 21 arranged in parallel with each other. The two support rods 21 are rotatably mounted on opposite sides of the bed body 1. The rotation axis of the support rods 21 is parallel to the width direction of the bed body 1. The limiting structure and driving structure of the support rods 21 are the same as the locking components and driving components in related technologies, which are existing technologies and will not be described in detail here.

[0031] Reference Figure 1 and Figure 2 The support rod 22 is located between the two support rods 21. The support rod 22 includes a horizontal section 221 and a connecting section 222 integrally formed at both ends of the horizontal section 221. The length direction of the horizontal section 221 is perpendicular to the length direction of the support rod 21. The horizontal section 221 is located at the end of the support rod 21 away from the bed frame 1. The dining board 23 is fixedly set on the side of the horizontal section 221 away from the support rod 21. When the support rod 21 is in a vertical state, the horizontal section 221 is located on the side of the bottom wall of the dining board 23 near the foot of the bed. The distance from the rotation point of the support rod 21 on the bed frame 1 to the dining board 23 is matched with the distance from the rotation point of the support rod 21 to the foot of the bed, so that when the support rod 21 is rotated to a horizontal state towards the foot of the bed, the dining board 23 can fit snugly against the foot of the bed for storage and does not take up much space.

[0032] Reference Figure 1 and Figure 2 The connecting segment 222 is arc-shaped. The connecting segment 222 on one side of the horizontal segment 221 is rotatably sleeved on the nearby support rod 21. The connecting segment 222 on the other side of the horizontal segment 221 is provided with a locking component. The locking component is used to fix or detach the connecting segment 222 relative to the nearby support rod 21.

[0033] Reference Figure 1 and Figure 2 The bed frame 1 has guardrails 3 installed on opposite sides, with two support rods 21 located between the guardrails 3 on both sides. The horizontal section 221 and the connecting section 222 are located above the guardrails 3 and the foot of the bed. During the process of the horizontal section 221 driving the dining board 23 to rotate, the connecting section 222 and the horizontal section 221 are less likely to interfere with the guardrails 3 and the foot of the bed.

[0034] When it is necessary to clean the tray 23, the connecting section 222 on the side of the support rod 22 away from its own rotation axis is disengaged from the nearby support rod 21 by the locking component. Then, the horizontal section 221 is rotated towards the foot of the bed. The horizontal section 221 drives the tray 23 to rotate along the support rod 21 on one side. Then, the tray 23 is moved to extend outside the bed frame 1. At this time, food scraps on the tray 23 can be cleaned. The trash can is placed near the edge of the tray 23 outside the bed frame 1 to facilitate pushing the food scraps into the trash can. The tray 23 can also be wiped with cleaning agent. Since the tray 23 extends outside the bed frame 1, food scraps are less likely to fall onto the bed frame 1 and contaminate the bedding when cleaning. After cleaning, rotate the horizontal section 221 in the opposite direction towards the foot of the bed, so that the horizontal section 221 drives the dining table 23 to rotate until it aligns with the detached support rod 21. Then, use the locking assembly to fix the connecting section 222 on the side of the support rod 22 away from its own rotation axis relative to the nearby support rod 21, thereby restoring the dining table 2 for easy storage and subsequent use.

[0035] Meanwhile, in this embodiment, the dining board 23 is rotated outside the bed 1, which can also be used when the patient needs to get out of bed during the meal. This means that the patient does not need to put away the dining table 2 when getting out of bed, and it is not easy to knock over the food on the dining board 23, which can meet a variety of usage scenarios.

[0036] Reference Figure 1 and Figure 2 The distance from the side of the guardrail 3 away from the head of the bed to the head of the bed frame 1 is greater than the distance from the support rod 21 to the head of the bed frame 1 when it is vertical. The upper end of the support rod 21, which is rotatably engaged with the support rod 22, is fixedly provided with a threaded section 4. The connecting section 222 near the threaded section 4 is provided with an internal thread 18 (refer to...). Figure 4 The internal thread 18 engages with the threaded section 4. The horizontal section 221 abuts against the guardrail 3. When the support rod 21 is vertical, the connecting section 222 drives the horizontal section 221 to rotate towards the foot of the bed, and the connecting section 222 on the side near the threaded section 4 rotates towards the bed frame 1. When the horizontal section 221 drives the tray 23 to rotate and extend beyond the bed frame 1, and the horizontal section 221 is parallel to the width direction of the bed frame 1, the horizontal section 221 is located above the guardrail 3 and abuts against the top of the guardrail 3. This helps the guardrail 3 to provide some support for the support rod 22 and tray 23 located outside the bed frame 1, reduces the load on the support rod 21 where the threaded section 4 is located, ensures the structural stability of the support rod 22 and the support rod 21, and also helps to limit the support rod 22, so that when the horizontal section 221 rotates to extend beyond the bed frame 1 and is parallel to the width direction of the bed frame 1, the horizontal section 221 cannot continue to rotate towards the head of the bed due to the abutment of the guardrail 3.

[0037] Reference Figure 2 and Figure 3To facilitate the fixing or disengagement of the connecting segment 222 on the side away from the threaded segment 4 from the adjacent support rod 21, the locking assembly includes a locking rod 15 and a connector 16. The locking rod 15 slides through the connecting segment 222 on the side away from the threaded segment 4, and the sliding direction of the locking rod 15 is parallel to the length direction of the support rod 21. A fixing ring 19 is fixedly sleeved on the locking rod 15. A limiting cavity 20 is formed in the connecting segment 222 on the side away from the threaded segment 4. The fixing ring 19 slides in the limiting cavity 20. The sliding cooperation between the fixing ring 19 and the limiting cavity 20 helps to guide the sliding of the locking rod 15, so that the locking rod 15 will not disengage from the corresponding connecting segment 222. A slot 17 is provided on the support rod 21 on the side away from the threaded section 4 for engaging with the locking rod 15. The slot 17 is located at the end of the support rod 21 away from the bed 1. A lever 24 is fixed on the side wall of the locking rod 15 away from the slot 17, which helps to slide the locking rod 15 by moving the lever 24. A connector 16 is provided on the locking rod 15 and is used to fix the locking rod 15 relative to the bottom wall of the slot 17.

[0038] Reference Figure 2 and Figure 3 To facilitate the relative fixation of the locking lever 15 to the bottom wall of the slot 17, the connector 16 includes a third hook and loop fastener 161 and a fourth hook and loop fastener 162. The third hook and loop fastener 161 is fixed to the side of the locking lever 15 near the support rod 21, and the fourth hook and loop fastener 162 is fixed to the bottom wall of the slot 17. The third hook and loop fastener 161 is used for adhesive engagement with the fourth hook and loop fastener 162. In other embodiments, the third hook and loop fastener 161 and the fourth hook and loop fastener 162 can be replaced with magnets that attract and engage with each other, which can also achieve relative fixation or disengagement of the locking lever 15 from the bottom wall of the slot 17.

[0039] When it is necessary to remove the dining board 23 from the bed frame 1, move the lever 24 away from the support rod 21. The lever 24 moves the locking rod 15 away from the slot 17, causing the third Velcro 161 on the locking rod 15 to disengage from the fourth Velcro 162 on the bottom wall of the slot 17. The end of the locking rod 15 near the support rod 21 moves into the corresponding connecting section 222. At this time, the connecting section 222 and the end of the support rod 21 are in a movable state, so that the support rod 22 can be rotated towards the foot of the bed to facilitate the cleaning of the dining board 23.

[0040] When cleaning is complete and the tray 23 needs to be reset, rotate the support rod 22 in the opposite direction towards the foot of the bed to reset it, so that the end of the locking rod 15 near the support rod 21 is kept in the corresponding connecting section 222, until the connecting section 222 on the side away from the threaded section 4 moves above the corresponding support rod 21, so that the locking rod 15 is aligned with the slot 17. Then move the locking rod 15 towards the slot 17, so that the third Velcro 161 on the locking rod 15 is bonded to the fourth Velcro 162 on the bottom wall of the slot 17, thereby preventing the locking rod 15 from moving without human intervention, which helps to ensure the relative fixation of the support rod 21 and the support rod 22.

[0041] Reference Figure 2 and Figure 4 An opening 6 is vertically formed on the connecting section 222 near the threaded section 4. A mounting cylinder 5 is vertically fixed to the top of the support rod 21 near the threaded section 4, and the mounting cylinder 5 is movably inserted into the opening 6. A receiving groove 7 is formed on the support rod 21 where the threaded section 4 is located. The depth of the receiving groove 7 is parallel to the length of the support rod 21, and the receiving groove 7 passes through the end of the corresponding support rod 21 away from the bed 1. The receiving groove 7 communicates with the mounting cylinder 5. A press-type disinfectant spray bottle 8 is placed in the receiving groove 7, extending into the mounting cylinder 5. The disinfectant spray bottle 8 can contain alcohol or other disinfectants, or cleaning agents. An elastic fixing ring 14 is fixed to the inner wall of the receiving groove 7. The fixing ring 14 can be a rubber ring, a silicone ring, or a plastic ring. The disinfectant spray bottle 8 is located within the fixing ring 14 and abuts against the inner wall of the fixing ring 14. The friction between the fixing ring 14 and the disinfectant spray bottle 8 helps to position the disinfectant spray bottle 8, preventing it from moving or rotating within the receiving groove 7.

[0042] Reference Figure 4 and Figure 5 The mounting cylinder 5 has a spray nozzle 9 on its side wall for dispensing disinfectant. The spray nozzle 9 is oriented away from the bed body 1. The cross-section of the spray nozzle 9 is larger than the nozzle of the disinfectant spray bottle 8. Even when the nozzle of the disinfectant spray bottle 8 is pressed, it still faces the spray nozzle 9. When the dining board 23 is located inside the bed body 1 and the horizontal section 221 is parallel to the width direction of the bed body 1, the connecting section 222 near the threaded section 4 blocks the spray nozzle 9. When the dining board 23 moves out of the bed body 1 and the horizontal section 221 is parallel to the width direction of the bed body 1, the spray nozzle 9 is located outside the corresponding connecting section 222 and is aligned with the dining board 23. The mounting cylinder 5 is equipped with a limiting component to restrict the movement of the disinfectant spray bottle 8 relative to the support rod 21. When the horizontal section 221 abuts against the guardrail 3, the spray nozzle 9 is located above the dining board 23.

[0043] Reference Figure 4 and Figure 5To facilitate limiting the movement of the disinfectant spray bottle 8 relative to the support rod 21, the limiting component includes a cover plate 10 and a pull member. The cover plate 10 is slidably disposed inside the mounting cylinder 5. The cover plate 10 is located on the side of the disinfectant spray bottle 8 away from the support rod 21. The sliding direction of the cover plate 10 is parallel to the length direction of the mounting cylinder 5. Connecting ears 28 are fixed on opposite sides of the cover plate 10. A sliding groove 25 is provided on the inner wall of the mounting cylinder 5 to slide and engage with the connecting ears 28. The sliding groove 25 passes through the end of the mounting cylinder 5 away from the support rod 21, so that the cover plate 10 can be removed from the mounting cylinder 5. The pull member is disposed inside the mounting cylinder 5 and is used to pull the cover plate 10 to abut against the nozzle of the disinfectant spray bottle 8.

[0044] Reference Figure 4 and Figure 5 To facilitate pulling the cover plate 10 to abut against the nozzle of the disinfectant spray bottle 8, the pulling component includes a spring 11. One end of the spring 11 is fixed to the inner wall of the mounting cylinder 5, and the other end is set on the cover plate 10. When the spring 11 is in its natural state, the cover plate 10 abuts against the nozzle of the disinfectant spray bottle 8, and the nozzle of the disinfectant spray bottle 8 is in its natural state.

[0045] Reference Figure 4 and Figure 5 The inner wall of the mounting cylinder 5 has a groove 26 along its length, which corresponds one-to-one with the sliding groove 25. The groove 26 is located on the side of the corresponding sliding groove 25 near the support rod 21, and the groove 26 communicates with the corresponding sliding groove 25. A connecting block 12 is slidably disposed in the groove 26. The length of the connecting block 12 is greater than the length of the connecting ear 28, so that the connecting block 12 can only slide within the groove 26, while the connecting ear 28 can move into the groove 26. The sliding direction of the connecting block 12 is parallel to the length direction of the mounting cylinder 5. One end of spring 11 is fixed to the bottom wall of groove 26, and the other end is fixed to the bottom wall of connecting block 12. The extension direction of spring 11 is parallel to the length direction of mounting cylinder 5. Spring 11 is connected to cover plate 10 through connecting block 12 and connecting ear 28. An operating groove 27 is provided on the side of cover plate 10 away from support rod 21 so that the user can take cover plate 10 out of mounting cylinder 5. Adhesive 13 is provided between connecting block 12 and corresponding connecting ear 28. Adhesive 13 is used to fix or detach connecting block 12 from connecting ear 28.

[0046] Reference Figure 4 and Figure 5 To facilitate the fixing or detachment of the connecting block 12 from the cover plate 10, the adhesive component 13 includes a first hook and loop fastener 131 and a second hook and loop fastener 132. The first hook and loop fastener 131 is fixed to the side of the connecting block 12 away from the spring 11, and the second hook and loop fastener 132 is fixed to the bottom wall of the connecting ear 28. The first hook and loop fastener 131 is used for adhesive engagement with the second hook and loop fastener 132. In other embodiments, the first hook and loop fastener 131 and the second hook and loop fastener 132 can be replaced by two magnets that are attracted and fixed to each other.

[0047] When the dining board 23 is in use inside the bed frame 1, the disinfectant spray bottle 8 is located inside the support rod 21 and the mounting cylinder 5 near the threaded section 4. At this time, the connecting section 222 near the threaded section 4 closes the spray nozzle 9. The cover plate 10 abuts against the nozzle of the disinfectant spray bottle 8 under the adhesion of the first Velcro 131 and the second Velcro 132, making it difficult to slide or fall off from the mounting cylinder 5, and closing the mounting cylinder 5 so that the disinfectant inside the disinfectant spray bottle 8 does not easily evaporate.

[0048] When the tray 23 needs to be rotated towards the foot of the bed and extended out of the bed frame 1, the connecting section 222 near the disinfectant spray bottle 8 is rotated downward along the corresponding support rod 21, so that the connecting section 222 gradually protrudes from the spray nozzle 9 until the tray 23 moves out of the bed frame 1. The horizontal section 221 is parallel to the width direction of the bed frame 1. At this time, the spray nozzle 9 is aligned with the tray 23. Then, the cover plate 10 is pressed down, so that the cover plate 10 abuts against the nozzle of the disinfectant spray bottle 8 and moves down. The connecting ear 28 abuts against the connecting block 12 and moves down, compressing the spring 11, so that the disinfectant spray bottle 8 sprays disinfectant onto the tray 23. The disinfectant is sprayed onto the tray 23 through the spray nozzle 9, which helps to disinfect the tray 23. The disinfectant will not be sprayed onto the bed frame 1, making it convenient to use and requiring no other space.

[0049] When it is necessary to replace the disinfectant spray bottle 8, insert your finger into the operating groove 27 and move the cover plate 10 away from the mounting cylinder 5. Since the connecting block 12 will not move upward due to the limiting effect of the groove 26, the cover plate 10 will cause the second Velcro 132 to detach from the first Velcro 131. At this time, the disinfectant spray bottle 8 can be taken out from the receiving groove 7 for replacement. After replacing the disinfectant spray bottle 8, align the connecting ear 28 on the cover plate 10 with the sliding groove 25 so that the cover plate 10 abuts against the nozzle of the disinfectant spray bottle 8. At this time, the second Velcro 132 on the connecting ear 28 and the first Velcro 131 on the connecting block 12 are bonded together, making it difficult for the cover plate 10 to detach from the mounting cylinder 5.

[0050] The implementation principle of this application embodiment is as follows: When the dining board 23 needs to be cleaned, the lever 24 is moved away from the support rod 21. The lever 24 drives the locking rod 15 away from the slot 17, causing the third Velcro 161 on the locking rod 15 to disengage from the fourth Velcro 162 on the bottom wall of the slot 17. The end of the locking rod 15 near the support rod 21 is completely moved into the corresponding connecting section 222. At this time, the connecting section 222 and the end of the support rod 21 are in a movable state. Then, the horizontal section 221 is rotated towards the foot of the bed, and the horizontal section 221 moves... The movable food tray 23 rotates along the support rod 21 on one side. The internal thread 18 engages with the threaded section 4, causing the connecting section 222 and the horizontal section 221 to move downwards as they rotate. The connecting section 222 gradually exposes the spray nozzle 9. Then, the food tray 23 extends outside the bed body 1, and the horizontal section 221 is parallel to the width direction of the bed body 1. The guardrail 3 abuts against the horizontal section 221 for support. At this time, food residue on the food tray 23 can be cleaned. The trash can is placed near the edge of the food tray 23 outside the bed body 1 to facilitate pushing the food residue into the trash can. Then, the food tray 23 is wiped.

[0051] Then press down on the cover plate 10 so that it abuts against the nozzle of the disinfectant spray bottle 8 and moves downward. The disinfectant spray bottle 8 sprays disinfectant onto the table board 23, which helps to disinfect the table board 23 and the disinfectant will not be sprayed onto the bed frame 1. At this time, the table board 23 can be wiped again so that the disinfectant on the table board 23 can be evenly distributed. Since the table board 23 is located outside the bed frame 1, food residue and disinfectant are less likely to fall onto the bed frame 1 and contaminate the bedding when cleaning.

[0052] After cleaning, rotate the horizontal section 221 in the opposite direction towards the foot of the bed, so that the horizontal section 221 drives the tray 23 to rotate until it aligns with the disengaged support rod 21 and the locking rod 15 aligns with the slot 17. Then move the locking rod 15 towards the slot 17 so that the third Velcro 161 on the locking rod 15 is attached to the fourth Velcro 162 on the bottom wall of the slot 17. This makes it difficult for the locking rod 15 to move without human intervention, ensuring the relative fixation of the support rod 21 and the support rod 22, which is convenient for storage and subsequent use.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
