Present embodiment mainly comprises: a base 1, be located at first bedstead 10 of base top, first driving device 50 that can 20, two kinds of bedsteads of upper and lower active second bedstead, drive first driving device 50 of second bedstead and drive second driving device 60 of first bedstead.

As Fig. 1, shown in 3, first bedstead 10 has a middle body 11 that is located at regularly on the aforementioned base, be hubbed on middle body the rear and front end first, two movable parts 12,13, first movable part 12 (one section) is the part that patient head couches, and driven and the angle that is inclined upwardly by second driving device 60, and first plate health that makes patient lifts and become the state of reclining or sit up, 13 liang of hinge segment of second movable part then are second part that couches of patient, and driven by second driving device 60, and the angle that is inclined upwardly, and patient's shank is lifted.

The middle body 11 of first bedstead 10, first and second movable part 12,13 be rectangular pivot body and which is provided with a plurality of fixed bed boards 14 that are parallel to each other laterally, again at interval, at ordinary times just by the health of this group bedstead with the support patient.

Second bedstead 20 is driven by first driving device 50, and vertically upper and lower moving is to be provided with a plurality of mobile bed plates 21 on this movable bed frame 20, and each mobile bed plate 21 is that the compartment of terrain is positioned among the adjacent gap of each fixed bed board 14.21 of fixed bed board 14 and mobile bed plates keep appropriate gap, with ccontaining side turn-off frame 30,40 and ventilate, also an electric fan can be set under bed in case of necessity, strengthen ventilatory effect.

Second bedstead 20 is to be located at the appropriate location of first bedstead, 10 belows and the dual-side of bedstead is installed with some support bars 22 respectively, in order to support mobile bed plate 21, make them under normal circumstances, the mobile bed plate 21 that is installed on the support bar 22 is to be positioned at fixed bed board 14 belows, and by first bedstead, 10 carrying patients, and do upper and lower back and forth when movable at mobile bed plate 21, be to exceed suitable position, to replace fixed bed board 14 carrying patients' body weight.It should be noted that at this: the length of support bar 22 need be higher than the thickness of fixing head 14 at least, in the time of so can making the upper and lower reciprocal animal movement of mobile bed plate 21, can exceed fixed bed board 14 end faces.

During for fear of mobile bed plate 21 upper and lower reciprocating motions, produce lateral displacement and cause stuck phenomenon, so the dual-side at first and second bedstead 10,20 and first bedstead 10 is provided with some guiding elements 70, as shown in Figure 4, this guiding elements 70 comprises that one vertically is installed in the side guide pin bushing 71 of first bedstead 10; And one be installed in each second bedstead 20 and can constitute by vertical reciprocating guide rod 72 in this guide pin bushing 71; Therefore, when second bedstead 20 is done upper and lower reciprocating motion, can make second bedstead, 20 unlikely generation lateral displacements cause the stuck phenomenon of bed board by the setting of this guiding elements 70.

As shown in Figure 3, in first driving device 50, mainly comprise: at least two are articulated on the base 1, Rocker arm 51,52 and be connected the connecting rod 53 of Rocker arm 51,52 ends, and power set 54, be to be located on the base 1, but be that drive link 53 and Rocker arm 51,52 back and forth wave.Rocker arm 51,52 is articulated in an end of base 1, a swing arm 55,56 also is permanently connected, this two swing arm 55,56 is to extend with the end tilts ground of identical angle by two Rocker arm 5s 1,52, and a plurality of connecting rods 57,58 are the end that is connected second bedstead 20 and swing arm 55,56.

Power set 54 are a pneumatic cylinder or hydraulic cylinder, can drive Rocker arm 51,52 and swing arm 55,56 reciprocally swingings, and moving second bedstead, the 20 upper and lower displacements of connecting rod 57, the 58 upper and lower shipper poles that drive, and make mobile bed plate 21 upper and lower moving.

As shown in Figure 5, when mobile bed plate 21 moves to the position that exceeds fixed bed board 14, patient's body wt is carried by mobile bed plate 21, as shown in Figure 6, when mobile bed plate 21 moved to the position that is lower than fixed bed board 14, then patient's body wt recovered again to be carried by the bed board on first bedstead 10.Therefore, drive second bedstead 20 and mobile bed plate 21 upper and lower moving by first driving device 50, just can make patient's health pressurized force alternately accept with fixed bed board 14 or mobile bed plate 21, therefore, it is general to make that patient's health and bed board position contacting change, and prevents that the patient body same position is oppressed by bed board for a long time, and makes bed board have airy gap, so, can promote the patient body blood circulation.

In addition, as shown in Figure 7, the structure of second driving device 60 of first bedstead 10 has and first driving device, 50 similar rocking arms 61,62, rocking arm 65,66 and connecting rod 63, power set 64.The end of rocking arm 65,66 utilizes first and second movable part 12,13 of a connecting rod 67,68 and first bedstead 10 to link together respectively, therefore, when power set 64 driving rocking arms 61,62 wave, can utilize first and second movable part 12, the 13 supports a little acclivitous states of connecting rod 67,68 with first bedstead 10, and the attitude that makes patient change the to couch attitude that sits up.

Shown in Fig. 2,8, it is vertical and parallelly be located at 32,42 and two groups of gripper shoes in the rotating shaft 31,41 abreast respectively with the rollover driving devices 33,43 that drive rotating shaft 31,41 rotations that two side turn-off frames 30,40 have a rotating shaft 31,41 that is erected at base 1 central authorities side by side abreast, a plurality of and this two rotating shaft 31,41 respectively.

It is that the compartment of terrain is arranged in the gap between fixed bed board 14 and the mobile bed plate 21 that each support lifts 32,42, as shown in Figure 9, when patient is stood up, then can utilize rollover driving device 33,43 to drive rotating shaft 31 or rotating shaft 41 rotations, is that an angle is lifted in the center rotation and make gripper shoe 32,42 with rotating shaft 31,41, therefore, can patient's health be dug left or dig to the right by plurality of support 32 or gripper shoe 42.

The rollover driving device 33,43 of driving side translation frame 30,40 mainly comprises: two are fixedly connected on the connecting rod 34,44 on the rotating shaft 31,41, and two liquid, pneumatic cylinder 35,45, be that an end is connected on the base 1, and the other end is connected with the end of connecting rod 34,44.Liquid gas pressure cylinder 35,45 promotes connecting rods 34,44 in the mat, just can drive rotating shaft 31 or rotating shaft 41 rotations, and make bracing frame 32 or bracing frame 42 become heeling condition, makes the turn on one's side purpose of an angle of patient to reach.

Fixed bed board 14, mobile bed plate 21, and the cushion of all laying strip on the bracing frame 32,42, make patient to couch comfily in the above, in addition, the cushion of strip also can change to continuous laying at fixed bed board 14, the full wafer shape cushion on mobile bed plate 21 and the bracing frame 33,43.

Upper and lower mobile can the reaching of the mobile bed plate 21 of present embodiment avoids the patient body fixed position to be oppressed for a long time, promote ventilation effect, and massage patient body, blood circulation promoting, and drive first and second movable part 12,13 of first bedstead 10 by second driving device, then can change patient bed attitude, and patient is sat up or recline, and side turn-off frame 30,40 can make patient's health, change into the state of rollover to the left or to the right by the state that originally lay low, and patient body pressurized place is constantly changed.

In addition, first and second driving device 50,60 of present embodiment and the driving device 34,44 and an automatic control system of side turn-off frame 30,40 combine, this sick bed of may command is fixed time every amount and is driven automatically, even discontinuously patient is carried out a series of supervisor action of lying on the back, lift lower limb, stand up and massage.
