Abstract
A tridimensional hospital bed comprises a bed surface, an under frame, a rocker system for rocking the bed surface, the first power output device for motoring the rocker system, a bending system for bending the bed surface, and the second power output device for motoring the bending system. Two link mechanisms drives the joggling of the bed surface and then realizes the back extending and leg bending of the patient. The utility model is characterized in that: the operation of the bending system changes the prior direct push-pull method of the bed surface to the double hinges push-pull method. In this way, the loads are distributed more evenly, the press is more reasonable, the moving turns more stable and the speed becomes steadier. Therefore, the utility model dramatically decreases the load of the power resource, eliminates the impulse inertia and enables the patients to feel more comfortable.
Description
(1) technical field
This utility model relates to a kind of three-dimensional sick bed.
(2) background technology
Existing medical health care bed, its bed surface can only carry out single-degree-of-freedom and change, and realizes horizontal position, partly sits the clinostatism conversion, maybe can only carry out the stretched side and change and tilt forward and back, and the prone position clinostatism that can provide is extremely limited, can't satisfy the requirement of medical and health work.
For this reason, the patent No. is the technical scheme that 97201838.7 Chinese utility model patent has proposed a kind of Bionic bed, this Bionic bed comprises bed surface, underframe, the rollover system of the described bed surface that is used to turn on one's side, first PTO that is used to drive described rollover system, the liter that is used for tortuous described bed surface are carried on the back bent lower limb system, be used to drive second PTO that described liter is carried on the back bent lower limb system, can make bed surface in rollover, carry out the complications of bed surface, realizing to the bent lower limb motion of liter back of the body, finish to human body stand up bionical.
The middle axillare of its header board has the extension that extends back, one connecting rod is hinged with the middle axillare of described extension and described back plate respectively, the middle axillare of this connecting rod, extension, back plate and the middle axillare of middle plate are formed a deformable tetragon, described tetragon constitutes described liter and carries on the back bent lower limb system, and this tetragon connects described second PTO.
The liter of this utility model is carried on the back bent lower limb system operation logic: by the direct push-and-pull tetragon of second PTO, thereby make tetragon produce the complications that distortion realizes bed surface.But because the direct push-and-pull bed surface of PTO is easy to produce very big impulse inertia, therefore the shake of bed surface appears easily in operation process.In addition, rise the dynamic action point of the bent leg mechanism of the back of the body and the hypotelorism of pivot point, just power arm is too short, and the overload that power source is born quickens the wearing and tearing of power source and wears out, and greatly reduces the service life of power source.Stressed unreasonable, load concentration.
