[0001] The utility model relates to the technical field of lumbar puncture, in particular to a telescopic special bed for lumbar puncture. Background Art

[0002] Lumbar puncture for cerebrospinal fluid examination and intrathecal injection of drugs are routine operations in the hematology department, but lumbar puncture has high requirements for the patient's body position, requiring the patient to curl up into a bow shape (lying on the left side, with the back close to the edge of the bed, the back plane perpendicular to the bed surface, the head close to the chest, the back arched towards the puncturist, the lower limbs flexed to the abdomen, and the hands hugging the knees), and continue for a period of time until the operation is completed.

[0003] A lumbar puncture bed is needed for lumbar puncture. Currently, most lumbar puncture beds cannot be retracted in height, and the heights of transfer beds are different. When dealing with immobile patients, it is not convenient to transfer the patients from the transfer bed to the lumbar puncture bed. Usually, manpower is used to transport the patients to the lumbar puncture bed. During the transportation process, the patients are likely to collide with the lumbar puncture bed, which not only easily injures the patients, but also easily causes damage to the lumbar puncture bed, resulting in poor safety. Therefore, we propose a special retractable bed for lumbar puncture. Utility Model Content

The top plate 3 is slidably connected to the top of the base 1 through the lifting assembly. The guide assembly is arranged between the base 1 and the top plate 3. The bed body 6 is slidably connected to the top of the top plate 3. The lifting assembly includes a threaded rod 12. Two threaded rods 12 are provided. Both of the two threaded rods 12 are rotatably connected to the top of the base 1. Two symmetrically distributed sliding sleeves 9 are connected to the top plate 3. The two sliding sleeves 9 are respectively threadedly connected to the two threaded rods 12. In some embodiments, the lifting assembly is used to drive the top plate 3 to slide on the top of the base 1, thereby driving the bed body 6 to slide. The height of the bed body 6 is then adjusted, and the two threaded rods 12 are rotated on the top of the base 1, so that the sliding sleeve 9 slides on the outside of the threaded rod 12, thereby driving the top plate 3 to slide, and the guide component guides the top plate 3 when sliding. This solves the problem that most lumbar puncture beds cannot be retracted in height, and the heights of transfer beds are different. When dealing with immobile patients, it is not convenient to transfer the patients from the transfer beds to the lumbar puncture beds. Usually, manpower is used to transport the patients to the lumbar puncture beds.
