Abstract
The utility model relates to an improved sitting mechanism in a multifunctional sickbed, and a sitting mechanism of a sickbed has the convenience for people to lie and sit and can make legs meet the physiological need of a human body to naturally sag when people sit. A bed drawer is composed of a body drawer, a buttock drawer and a leg drawer, wherein both ends of the buttock drawer are respectively connected in a hinge mode with the body drawer and the leg drawer, so the leg drawer and the body drawer can be forwards rotated by winding the fulcra of the leg drawer and the body drawer, and a pair of lever linkage devices, which is respectively and axially connected with both sides of the body drawer and the leg drawer, is respectively provided with angle locking devices.
Description
This utility model relates to sick bed, works the improvement of sitting mechanism in particularly multifunctional hospital bed.
Patient's lying on bed for a long time sick bed of being in hospital often wishes can rise seat a period of time.Yet critically ill patient needs the nursing staff to help to rise and retire because of unable oneself's control.Present condition is hospital bed preferably, generally all has the body drawer upwards to turn up the function that forms backrest, mainly contains two types: the one, and hand spinning roller, driven wheel, ratch are upwards turned up the body drawer; The 2nd, be power jack-up body drawer with the motor, and can be by patient-controlled.Chinese patent 93227642.2 " the automatic conversion sick bed of multi-functional position " has been introduced the sick bed with above-mentioned functions, needs configuration motor, decelerator, control circuit etc., though automaticity is higher, but complex structure, inconvenient maintenance, its fancy price make the general hospital be difficult to bear.In practicality, also be subject to the influence that has a power failure in addition.Further to now all can rise and sit the sick bed analysis, after patient played seat, shank was still located level, even rectangular with the upper body.Yet human body natural's physiological requirement is that when being in the seat attitude, the shank natural torsion is sagging.Therefore on operating beds patient because of uncomfortable can't sitting, be unfavorable for state of an illness early recovery.
The purpose of this utility model be for multifunctional hospital bed provide a kind of sit crouch convenient, shank can the sagging sick bed that can satisfy human body natural's physiological requirement rise and sits mechanism when sitting attitude.
Design of the present utility model is: comprise the bed drawer of forming by body drawer, buttocks drawer and lower limb drawer, and wherein body drawer and the hinge connection of buttocks drawer, feature is that the lower limb drawer is connected with buttocks drawer hinge type; With body drawer, buttocks drawer and lower limb drawer two side shafts a pair of lever linkage even the angle locking device is arranged respectively respectively.
Above-mentioned lever linkage is made up of lower limb drawer connecting rod, buttocks drawer connecting rod, body drawer connecting rod and dowel steel, and wherein lower limb drawer connecting rod, buttocks drawer connecting rod become fulcrum shaft to connect with dowel steel, and the dowel steel other end becomes fulcrum shaft to connect with body drawer connecting rod.
Above-mentioned angle lock device is formed by being loaded on the vertical handle of body drawer, the flexible axle that is connected with handle, the kelly that is connected with flexible axle and tooth bar, the kelly top can with the tooth bar clutch.Tooth bar can directly be formed on below the buttocks drawer, and it is fixing also can to walk abreast separately.
In the above-mentioned handle handle is housed, the heart yearn of two flexible axles passes these handle two ends respectively and is connected with fixture block.
Sick bed provided by the utility model rises sits mechanism, and nursing staff's pull handle just can conveniently make patient play seat; Decontrol handle, kelly promptly snaps in tooth bar, realizes angle locking, and then realizes that the inclination angle of body drawer (backrest) and lower limb drawer has level adjustable.The pulling handle makes kelly separate with tooth bar by flexible axle, makes the angle activity of lever linkage, and arm-chair can become bed again.Particularly be provided with lower limb drawer connecting rod in the lever linkage, when patient played seat, shank can be put downwards automatically, and when patient liied in bed, shank can be set level again naturally, had satisfied the natural demand of human body, helped patient's rehabilitation.And the design is simple in structure, easy to operate, with low cost.
Embodiment is described further below in conjunction with accompanying drawing.
In the accompanying drawing, Fig. 1 is the side view of present embodiment, and Fig. 2 is grip structure figure among Fig. 1, and Fig. 3 is the oblique view of present embodiment.
With reference to accompanying drawing, form the bed body by the front and back head of a bed 1,11 and bed beam 24, bed beam 24 can be laid body drawer 9, buttocks drawer 2 and lower limb drawer 19, can lay the drawer pad respectively on each drawer.Each uses pivot pin 18 and 17 companies of connecting rod lower limb drawer 19 both sides, and each uses pivot pin 4 and 3 companies of connecting rod buttocks drawer 2 both sides, and body drawer 9 and connecting rod 23 are connected.Lower limb drawer 19 realizes and buttocks drawer 2 hinges that by pivot pin 16 buttocks drawer 2 realizes and body drawer 9 hinges that by pivot pin 7 above-mentioned pivot pin 16,7 all passes a beam 24.The end of lower limb drawer connecting rod 17 and buttocks drawer connecting rod 3 and 15 companies of dowel steel 14 usefulness pivot pins, the other end of dowel steel 14 and 12 companies of body drawer connecting rod 23 usefulness pivot pins, thus formed the lever linkage that lower limb drawer and body drawer are forward rotated around fulcrum separately.In order to improve shockproof effect, dowel steel 14 can be contacted with shock-absorbing bar 13.
The angle locking device is formed by being formed on buttocks drawer 2 following tooth bar 5, card articles 22, and card article 22 ends connect with connecting rod 23 rotatable shafts.In card article 22 tops snap in tooth bar 5 teeth, be about to the Φ angle lock, thereby the inclination angle of body drawer (backrest) and lower limb drawer is fixed.The card article top snaps in the different teeth, and the Φ angle changes thereupon.When the Φ angle increases (dwindling), lower limb drawer 19 around fulcrum (pivot pin) 16 upwards (descend) rotate, simultaneously body drawer 9 around fulcrum (pivot pin) 7 downwards (on) rotate the change of realization bed-chair.
Angle controller is made up of flexible axle 10, the extension spring 6 of handle 8, similar bicycle brake line.Extension spring 6 connects buttocks drawer 2 and card articles 22, is used for card article 22 resetted snapping in the tooth, and flexible axle 10 1 ends connect handle 8, and the other end connects card article 22, is used for card article 22 is broken away from tooth bars 5.
Be installed on body drawer 9 vertical handle 8 structures as shown in Figure 2, have the heart yearn of 20, two flexible axles 10 of a handle to pass handle 20 two ends in it and fixture block 21 is connected.When on pull handle 8 because extension spring 6 and lever linkage effect effect, promptly forward sliding along tooth bar 5 in card article 22 tops, when forwarding comfortable angle to, unclamps handle, card article 22 tops are promptly snapped in certain tooth by extension spring 6, the Φ angle promptly is fixed.Realize that bed-chair changes, otherwise when pulling handle 20, because fixture block 21 effects, the heart yearn of flexible axle 10 is spurred upwards promptly, thereby pulling card article 22 breaks away from tooth bar 5, the opening angle locking device, body drawer and lower limb drawer can reset, and realize chair-bed conversion.
