Description

The ventilation sick bed

This utility model belongs to bed, the ventilation sick bed that particularly a kind of patient uses.

The ventilation sick bed of commonly using, as shown in Figure 8, it is made up of separately get in and out of bed group of slats and driving mechanism, driving mechanism is made up of motor, chain transmission and camshaft, be interval with the phase angle on the camshaft and differ two groups of eccentrics of 180 °, and make these two groups of eccentrics be against respectively getting in and out of bed plank bed group below.Push the group of slats that gets in and out of bed by the eccentric group of drive mechanism during use and move, alternately contact human body, thereby reach the purpose of ventilating and preventing to give birth to decubital ulcer by the upper and lower fluctuating of the group of slats that gets in and out of bed relative to upper and lower.The ventilation sick bed of this structure, during not only complex structure, and running, the driving mechanism noise is very big, influences patients ' recovery and aggravation nursing staff's degree of fatigue.

The purpose of this utility model provides a kind of simple in structure, noiselessness that operates steadily, ventilation sick bed that serviceability is good.

This utility model is made up of quiet bedstead, movable bed frame and driving mechanism, and quiet bedstead is made up of bed body, top frame and quiet bed group of slats, and bed body both sides are provided with guiding piece, and quiet bed board bar is laid on the body top top frame at interval; The movable bed frame is made up of moving framework and movable bed group of slats, moving framework both sides are provided with the guiding piece with bed body two side guides fits, its top with support bar be provided with quiet bedstead on the quiet bed board bar movable bed lath that staggers and lay at interval, the movable bed chord position is in the top frame below of quiet bedstead; Driving mechanism is made up of driving cylinder, lever, fulcrum bar and push rod, the lever middle part is hinged on the bed body through the fulcrum bar, the one end is positioned at the driving cylinder below and conflicts with the driving cylinder moving member, and its other end and push rod are hinged, and the other end of push rod is installed on the moving framework of movable bed frame.

Because this utility model is made up of quiet bedstead, movable bed frame and driving mechanism, quiet bedstead is made up of bed body, top frame and quiet bed group of slats, and bed body both sides are provided with guiding piece, and quiet bed board bar is laid on the body top top frame at interval; The movable bed frame is made up of moving framework and movable bed group of slats, moving framework both sides are provided with the guiding piece with bed body two side guides fits, its top with support bar be provided with quiet bedstead on the quiet bed board bar movable bed lath that staggers and lay at interval, the movable bed chord position is in the top frame below of quiet bedstead; Driving mechanism is made up of driving cylinder, lever, fulcrum bar and push rod, the lever middle part is hinged on the bed body through the fulcrum bar, the one end is positioned at the driving cylinder below and conflicts with the driving cylinder moving member, and its other end and push rod dumpling connect, and the other end of push rod is installed on the moving framework of movable bed frame.During use, the driving cylinder moving member moves down, and moves down with the lever end of its conflict, and lever is swung around the fulcrum bar, the other end jack-up push rod of lever moves thereby make on the movable bed frame, and the movable bed lath that staggers with quiet bed board bar on it passes on the gap between the adjacent two quiet bed board bars and moves and contact with human body; When driving cylinder resetted, the movable bed frame moved down under the deadweight effect, and movable bed lath breaks away from human body on it, by quiet bed board bar contact human body, reached the effect of ventilating and massaging, and is not only simple in structure, and the noiselessness that operates steadily, thereby reaches the purpose of this utility model.

Below in conjunction with accompanying drawing this utility model is further elaborated.

As Fig. 1, shown in Figure 2, this utility model is by quiet bedstead 1, movable bed frame 2 and driving mechanism 3 are formed, quiet bedstead 1 is by bed body 11, top frame 12, quiet bed group of slats 13 and ventilation type foam rubber cushion 14 are formed, as shown in Figure 4, bed body 11 both sides are provided with the guide pin bushing 111 as guiding piece, top frame 12 can be a plane framework, it can also be bendable top frame 15 as shown in Figure 7, bendable top frame 15 is followed successively by in the past backward can upwards bend anterior 151, fix smooth middle part 152 and can upwards be bent into triangular shape rear portion 153, quiet bed group of slats 13 is laid on a body 11 top top frames 12 (15) at interval, and make between the adjacent bed board bar 131 and be provided with gap 132, ventilation type foam rubber cushion 14 can be a whole pad, can also be the ventilative foam rubber cushion of strip that is installed on the quiet bed group of slats 13; Movable bed frame 2 is made up of moving framework 21 and movable bed group of slats 22, can also on movable bed group of slats 22, install the ventilative foam rubber cushion 23 of strip, moving framework 21 both sides are provided with the guide rod 211 with bed body 11 both sides guide pin bushings 111 fits, moving framework 21 tops are provided with the movable bed lath 221 that staggers and lay at interval with quiet bed group of slats 13 through support bar 24, and the width that makes movable bed lath 221 is less than the length of the gap 132 of quiet bed group of slats 13 and support bar 24 thickness greater than quiet bed board bar 131, and movable bed frame 2 is positioned at the below of the top frame 12 (15) of quiet bedstead 1; Driving mechanism 3 is made up of driving cylinder 31, lever 32, fulcrum bar 33 and push rod 34, driving cylinder 31 is the pneumatic linear actuator by solenoid control, as shown in Figure 3, lever 32 is a JiongXing Jia, its end that is connected by cross bar 321 is positioned at driving cylinder 31 belows and conflicts with the moving member 311 of driving cylinder 31, its middle part is hinged on bed body 11 through fulcrum bar 33, and its other end and push rod 34 are hinged, and the other end of push rod 34 is installed on the moving framework 21 of movable bed frame 2.
