Description

Technical Field

[0001] The utility model relates to the technical field of hospital bed guardrails, in particular to a four-section lifting guardrail. Background Art

[0002] Early hospital beds did not have guardrails on both sides of the bed, which was extremely inconvenient for patients who had difficulty getting up or lying down on their own. They could only lie down or get up with the help of medical staff, family members, fellow patients or other people. Moreover, patients could easily fall off the bed when turning over, especially children. Later hospital beds had guardrails specially welded on both sides of the bed, so that patients who had difficulty getting up or lying down on their own could use the support of the guardrails to get up or lie down by themselves without having to wait for help from others, which made it much more convenient to use.

[0003] In the patent document with the authorized announcement number CN208626060U, a retractable and foldable bed guardrail is disclosed.
