[0001] This utility model relates to the field of medical care, and in particular to a lifting nursing cart. Background Technology

[0002] In the medical process, in order to ensure the rapid and healthy recovery of patients, medical staff often need to provide care for patients. This process is usually carried out by specialized nursing staff on a regular schedule. The work area of ​​a group of nursing staff often covers a large area of ​​the ward and involves various nursing needs. Therefore, during the nursing work, medical staff usually need to classify and place various nursing instruments on a trolley, push it to different patients, and then take out the corresponding instruments for care.

[0003] Different patients require different areas of care. For example, some patients have leg injuries and their legs are elevated, making the operating surface of traditional nursing carts too low and inconvenient for staff to operate. Moreover, for the same nursing cart, the height of medical staff varies, making it difficult to match the height of the operating table with their height. This can cause inconvenience for medical staff when preparing medications or retrieving instruments. Utility Model Content

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0029] Please see Figure 1-8 This utility model provides an embodiment of a lifting nursing trolley, comprising a base 10 and an operating table 11. Four support components for easy lifting and extension are distributed and installed between the base 10 and the operating table 11. A drawer 13 is fixedly installed on the bottom surface of the operating table 11 for storing fragile items. A railing 12 is fixedly installed at the edge of the upper surface of the operating table 11 for easy pushing and moving. The support components include a support base cylinder 15 fixedly installed on the upper surface of the base 10. Several locking teeth 23 are equidistantly distributed on the arc-shaped sidewalls on both sides of the inner cavity of the support base cylinder 15. A support slide rod 16 is slidably installed in the middle of the inner cavity of the support base cylinder 15. The upper surface of the support slide rod 16 is fixedly connected to the bottom of the operating table 11. Each support slide rod 16 is provided with a sliding cavity 22, and each sliding cavity 22 is slidably connected to... An inner slide rod 20 is connected to the inner slide rod 20 on the left and right sides. A connecting plate 17 is fixedly connected between two inner slide rods 20 located on the same side. Two L-shaped limiting plates 21 are slidably installed at the bottom of the sliding cavity 22. The horizontal part of each L-shaped limiting plate 21 penetrates through the outer end face of the supporting slide rod 16 and extends into the inner cavity of the supporting bottom cylinder 15, and can be embedded in the locking tooth part 23. A triangular part 24 is fixedly connected to the vertical part of each L-shaped limiting plate 21. The two triangular parts 24 are staggered front and rear. A return spring is connected between the two L-shaped limiting plates 21. The triangular head at the bottom of the inner slide rod 20 can slide and abut against the inclined surface of the triangular part 24, so that when it moves downward, it can abut against the inclined surface of the triangular part 24, and at the same time, it squeezes the two triangular parts 24 to both sides, so that the triangular parts 24 extend out and abut against the locking tooth part 23 and are locked.

[0030] It should be noted that, in order to further facilitate the staff in adjusting the height of the operating table 11 for patient care, in this embodiment, the lower end face of the operating table 11 is provided with a groove 19 at the position of each connecting plate 17. A compression spring is connected to the upper sidewall of the corresponding groove 19 at both ends of the upper end face of each connecting plate 17. An L-shaped extension plate 18 is fixedly installed on the groove 19, so that when the operating table 11 needs to be raised, the staff only needs to place their hands on the corresponding L-shaped extension plate 18 and press the L-shaped extension plate 18 upwards, thereby causing the connecting plate 17 to move upwards, which in turn drives the inner sliding rods 20 on both sides to slide upwards, so that the... When the triangular head at the bottom of the inner slide rod 20 disengages from the corresponding two triangular portions 24, the two L-shaped limiting plates 21, lacking contact, will reset under the action of the return spring. This causes the two L-shaped limiting plates 21 to slide closer to the center line of the inner slide rod 20, thus disengaging from the locking teeth 23. This allows the entire support slide rod 16 to be easily pulled upwards, raising the operating table 11 to a suitable height. Then, the L-shaped extension plates 18 on both sides can be released. Under the action of the compression spring, the triangular head at the bottom of the inner slide rod 20 will re-insert between the two triangular portions 24, causing the L-shaped limiting plates 21 to re-lock onto the locking teeth 23 at the corresponding height.

[0031] It should also be noted that friction stripes can be provided on the outer end face of the L-shaped extension plate 18 to increase the friction with the hand, thus facilitating adjustment by the staff.

[0032] In practice, when medical staff need to care for a patient, they first place the necessary medications and instruments in the drawer 13. The medical staff can then push the railing 12 and move it using the casters 14 at the bottom of the base 10. When care is needed, to facilitate operation, the operating table 11 needs to be adjusted to a suitable height. At this time, both hands are placed on the corresponding L-shaped extension plate 18, and the L-shaped extension plate 18 is pressed upwards, causing the connecting plate 17 to move upwards. This, in turn, causes the inner sliding rods 20 on both sides to slide upwards, disengaging the triangular heads at the bottom of the inner sliding rods 20 from the corresponding two triangular portions 24. At this point, the two L-shaped limiting plates... If the L-shaped limiting plates 21 lack contact, they will reset under the action of the return spring, causing the two L-shaped limiting plates 21 to slide towards the center line of the inner slide rod 20, thus not contacting the locking teeth 23. This allows the entire support slide rod 16 to be easily pulled up, raising the operating table 11 to a suitable height. Then, the L-shaped extension plates 18 on both sides can be released. Under the action of the compression spring, the triangular head at the bottom of the inner slide rod 20 will re-insert between the two triangular parts 24, causing the L-shaped limiting plates 21 to re-lock onto the locking teeth 23 at the corresponding height. This adjusts the operating table 11 to a suitable height, facilitating operation by medical personnel on the operating table 11.

[0033] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
