Bedsore-preventing defecation-assisting automatic bed trolley

Abstract

The invention particularly relates to a bedsore-preventing defecation-assisting automatic bed trolley. A first cushion body is installed on the upper surfaces of a seat frame and a back frame. A first pushing frame and a first connecting rod are arranged on the seat frame. A first rotating shaft is arranged on the back frame. The first pushing frame is connected with the first connecting rod. A second connecting rod and a second pushing frame are arranged on the back frame. The second pushing frame is connected with a second connecting rod, the other end of the first pushing frame is connected with the other end of the second pushing frame through a force-bearing flexible belt, the other end of the second connecting rod is connected with a rotating rod, the rotating rod is connected with a second motor, and one end of the second motor is fixed to the back frame. A tough drawstring is arranged on the bottom surface of the first cushion body, one end of the tough drawstring is connected to the first rotating shaft, and the other end of the tough drawstring is connected to the seat frame. The automatic bed trolley has the beneficial effects that through combined use of the back frame, the second connecting rod, the second pushing frame, the rotating rod and the motor, the first cushion body is in an arched state, contact between a human body and the first cushion body is reduced, and therefore the bedsore problem is relieved.

Description

technical field [0001] The invention relates to the technical field of automatic bed carts, in particular to an automatic bed cart for preventing decubitus ulcers and aiding defecation. Background technique [0002] The long-term bedridden disabled people have long-term contact with hard objects (bed boards) on the back shoulder blades, spine, and pubic bones, resulting in long-term poor blood circulation in the vicinity of these places, resulting in decubitus ulcers. In view of the fact that the automatic bed car must be transformed into a wheelchair shape with a movable posture in addition to being able to lie down, it needs to meet the requirements of passing through a certain relatively limited width passage or through the door width and keep it relatively narrower than the width of an ordinary single bed, and it can Gain the flexibility of moving with the tightest turning radius. Therefore, the rollover measures in solving the conventional anti-decubitus bed constructi...

Problems solved by technology

The push rod axis of the wheel protruding outward moves linearly, and the rear wheel supports the linear slider by pushing back, and the double-arc connecting rods on both sides need to have a certain fit clearance relationship, including the unavoidable clearance of the screw fit at the joint. And the gap between the threaded sleeve and the screw rod in the inner telescopic tube allows it to rotate at a certain angle.

When the extension distance of the telescopic rods of the rear wheels becomes larger, the double rear wheels will show a more obvious "eight" shape, and the telescopic rods will protrude from horizontal to slightly downward, resulting in the same The threaded sleeve connected to the rear telescopic rod crushes the screw and cannot rotate, causing the wheel to turn outward, which ultimately affects the transmission effect
