An expandable hospital bed

Abstract

An extendable hospital bed comprising a bed frame (2) used for supporting a bed surface and bed legs (1) arranged at either end of the bed frame (2). Width-extending frames (3) and a bedhead extending frame (4) arranged at an extremity of the bed frame (2) are provided on the bed frame (2). The width-extending frames (3) are arranged in parallel in the transverse direction of the bed frame (2). The bed frame (2), the width-extending frame (3), and the bedhead extending frame (4) are jointly laid to for the bed surface. A first hollow pipe (31) arranged in the transverse direction of the bed frame (2) is provided on the bed frame (2). A first insertion pipe (32) that can be slidably inserted into the first hollow pipe (31) is provided on the width-extending frame (3). A transverse support bar (33) is provided on the width-extending frame (3). One extremity of the transverse support bar (33) is connected onto the width-extending frames (3), while the other extremity is dragged on the bed frame (2). The bed frame (2) is provided with a second hollow pipe (41) arranged in the longitudinal direction of the bed frame (2). A third hollow pipe (43) parallel to the first hollow pipe (31) is provided on the bedhead extending frame (4). A second insertion pipe (42) that can be slidably inserted into the second hollow pipe (41) is fixed onto the bedhead extending frame (4). One extremity of one right-angled bent insertion pipe (44) is slidably inserted into the third hollow pipe (43), while the other extremity is inserted into a longitudinal hollow pipe of the adjacent width-extending frame (3). The bedhead extending frame (4) is connected to a longitudinal support bar (45). One extremity of the longitudinal support bar (45) is connected onto the bedhead extending frame (4), while the other extremity is dragged on the bed frame (2).

Description

technical field [0001] The invention relates to a hospital bed. Background technique [0002] The length and width of the bed surface of existing hospital bed all are fixed, and the movement of sick bed generally relies on the rolling of the wheel under the bed leg of sick bed. For a room where the door is not wide enough, the movement of the sick bed is limited by the width of the door. When the door was smaller than the width of the sick bed, the sick bed was difficult to move out or into the room. Especially when catastrophic accidents such as fires and earthquakes took place, the poor passage of sickbeds would endanger the lives of patients. [0003] In addition, during the sales and transportation of the hospital bed, although the general hospital bed has a folding structure, the width and total length of the hospital bed cannot be changed. raised. From the viewpoint of movement and transportation of the hospital bed, the size of the hospital bed needs to be reduced....

AI Technical Summary

Problems solved by technology

[0004] However, from the point of view of use, patients have greater requirements for the length and width of the hospital bed, and require a larger size.

Moreover, hospital beds generally have standard sizes, and for particularly tall patients, the beds are often not long enough or wide enough

Existing hospital beds cannot adjust the size of the bed surface, which brings inconvenience
