Abstract

The utility model discloses a nursing bed which comprises a bracket, and the bracket is provided with a bed body. When the bed body is erected, a backrest, a base seat and a swing leg are formed, the backrest, the base seat, the swing leg and arm rests form a hinge four-bar mechanism which is provided with a locking mechanism on any hinge position, and control rod pieces of the locking mechanism correspondingly rotate. The utility model is particularly suitable for hospitals, sanatoriums, bedridden patients and old people who can not walk freely at home to use. The utility model can provide a convenient sitting position for patients in the state of being erected, which causes legs and feet to swing down and not easy to be tired. The utility model can also conveniently carry out the cleanness of urination and defecation and the care of turning over for the patients.

Description

Nursing bed

Technical field this utility model relates to a kind of bed that nurses the sick, and is particularly suitable for patient that hospital, sanatorium's long-term bed do not rise and handicapped in the family old people and uses.

Background technology is present, is generally using the elevated nursing bed of the head of a bed in hospitals at different levels, and this bed provides convenience to a certain extent for nursing the sick, and it can make patient sit up and have a dinner.Yet because patient's shank and foot can not form the bottom, this sitting posture glides easily, patient for a long time seat can produce uncomfortable, be prone to fatigue.

The summary of the invention the purpose of this utility model will provide a kind of improved nursing bed exactly, and it can not only overcome the deficiency that existing nursing bed exists effectively, but also can also stand up for patient easily simultaneously easily for patient clears up defecation.

The purpose of this utility model is to realize like this, described nursing bed has support, and a body is arranged on the support, and the bed body props up time-out and forms backrest, base, swinging kick, backrest, base, swinging kick and handrail form four-bar linkage, are provided with control rod member retaining mechanism in relative rotation at arbitrary hinge position.

As a kind of improvement project of the present utility model, the four-bar linkage of described nursing bed is a parallel double crank mechanism, and retaining mechanism is arranged on the hinge position between backrest and the base.

As another kind of improvement project of the present utility model, the support of described nursing bed is by the support of mechanical hand realization to hinge, and whole parallel double crank mechanism is provided with the retaining mechanism that rotates around hinge center between backrest and the base.

As the further improvement of the utility model scheme, the support of described nursing bed is provided with respectively to left and right supporter of pulling out, supporter upper end supporting bed body, and a bed body top hasp has stretcher.

This utility model has especially adopted parallel double crank mechanism owing to adopted four-bar linkage, make the backrest of a body can be easily from level to vertically being converted into the position that needs.Simultaneously, the swinging kick of bed body is the bottom thereupon, makes patient's sitting posture be in comparatively comfortable state.

This utility model also owing to adopted mechanical hand that hinge is supported, can be realized turning over an angle after the body sitting posture state integral body, to clear up patient's defecation easily easily.

This utility model is also owing to be provided with supporter at the support two ends, and hasp has stretcher above the bed body, makes standing up of patient become more or less freely, has realized the convenient nursing to patient.

Description of drawings is described in further detail nursing bed of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the front view of this utility model nursing bed bed body;

Fig. 2 is the vertical view of nursing bed bed body shown in Figure 1;

Fig. 3 is the structure principle chart that this utility model nursing bed is propped state;

Fig. 4 is the structure principle chart of the another kind of embodiment of this utility model;

Fig. 5 is the structure principle chart after the described mechanical hand of this utility model nursing bed amplifies;

Fig. 6 is the structure principle chart of the third embodiment of this utility model.

State when specific embodiment Fig. 1, Fig. 2 show of the present utility model body horizontal positioned.At this moment, backrest 1, base 2, swinging kick 3, handrail 4 places are in one plane.Fig. 3 shows the relative position relation of propping each parts of state nursing bed.Backrest 1, base 2, swinging kick 3 forms parallel double crank mechanisms with handrail 4, make between backrest 1 and the swinging kick 3, in the certain angle scope, can remain between handrail 4 and the base 2 parallel.Whole double-crank mechanism is fixed on the support 5 by mechanical hand 8, and the angle between the horizontal plane of backrest 1 and support 5 can be regulated arbitrarily 90 ° of scopes.Backrest 1 forms an imposite on whole short transverse, swinging kick 3 forms the rod member that solid plate, part more than the hinge form parallel double crank mechanism in the part below the hinge.Hinge place 2 of backrest 1 and bases is provided with ratchet, ratchet retaining mechanism.When adjusting to the position of needs, ratchet combines with ratchet, makes parallel double crank mechanism become a rigid body.This utility model is installed wheel on support 5 just become wheelchair.The same less universal wheel of diameter that adopts with common wheelchair of the front-wheel of wheelchair, trailing wheel adopt the semiaxis mode directly to insert the beam barrel that is located on the support 5 as main BOGEY WHEEL.

Fig. 4 shows parallel double crank mechanism that backrest 1, base 2, swinging kick 3 and handrail 4 form as a rigid body, leans around hinge between the back of the body 1, the base 2 structure when turning over certain angle counterclockwise.Mechanical hand 8 is fixed on the support 5, and the mechanical hand 8 on the right is in open state, and the mechanical hand 8 on the left side is in closure state.When the rigid body of parallel double crank mechanism formation forwards suitable position counterclockwise to, it is locked by the ratchet, the ratchet retaining mechanism that are located on the support 5.At this moment, can realize cleaning-nursing easily to patient's lower part of the body.Fig. 5 shows the structure of mechanical hand 8, is not having external force to do the time spent, and handgrip 9 opens under the effect of tension spring 10; When parallel double crank mechanism integral body clockwise rotates, when the hinge axis of 3 of bases 2, swinging kick is put into handgrip 9, compression spring 11 is depressed, handgrip 9 is closed under mechanical hand 8 shell forceful action, control stick in the control valve 12 inserts the body of rod in the compression spring 11 under spring action, mechanical hand 8 can not open voluntarily; When control valve 12 control sticks moved to left, compression spring 11 was released, and behind the pressure on releasing mechanical hand 8 tops, handgrip 9 opens.

As the third embodiment of the present utility model, on the basis of embodiment shown in Figure 4, the bed body of this utility model nursing bed at first is adjusted to Fig. 1, pattern shown in Figure 2 and locking exactly, then to the left and right supporter 6 that is located on the support 5 of pulling out, supporter 6 upper end supporting bed bodies, bed body top hasp stretcher 7.Release mechanism hands 8, the gear on the supporter 6 that hoists, tooth bar elevating mechanism are then with ratchet, detent mechanism locking.Rotate the bed body this moment and reach the stretcher 7 that snaps over it together, the patient who lies on the body has promptly realized standing up.Remove a body, reduce stretcher 7 to support 5, patient promptly can another kind of posture has a rest on stretcher 7 or to nursery works such as it clean.Poly-with the above-mentioned same step, also stretcher 7 can be removed, change upper bed body again, make nursing bed return to conventional state.Rotating shaft place at bed body two ends is provided with positioning disk, when the bed body forwards a certain angle to, with alignment pin positioning disk is located, and makes a body be parked in the relevant position, and bed body dual-side also can be realized turn on one's side nursing under the certain angle state of patient after baffle plate is set.
