Description

Multifunctional wheelchair

This utility model belongs to lower extremity paralysis patient life, medical care wheelchair.

ZL95225282.1 " multifunctional wheelchair " is the first generation product that we develop, and this wheelchair can be realized the function of seat, clinostatism and walking by the own regulating handle of lower extremity paralysis patient, and the defecation of can also taking care of oneself, and need not other people nursing.Its seat, the conversion of clinostatism realizes by hydraulic lift, the lifting control valve of hydraulic lift and decline control valve all are fixed on the side of a side handrail, promote, the following of decline control valve is fuel tank, fuel tank is connected with hydraulic lift by joint and flexible pipe, in fuel tank, valve piston cylinder and oil extraction cylinder are arranged, in the valve piston cylinder small piston rod is arranged, the valve piston cylinder communicates with the oil extraction cylinder by valve base channel, sealed steel ball is arranged at the bottom of oil extraction cylinder, the compression spring, sealing ring, the oil extraction bar, also have outage on the oil extraction cylinder, the top of oil extraction bar is the decline control valve of eccentric wheel structure, and the top of small piston rod is for promoting control valve.Find in the practice, adopt this up-down mode, the easy leakage of oil of fuel tank has a very big potential safety hazard in case repairing is untimely.The lifting of bedpan is to be fulcrum with the boatswain chair that is fixed on the seat face in addition, the lower end of boatswain chair is connected with fork by live axle, the branch beginning of fork is inserted in respectively just between groove and two two way slide lanes, the indiscrete end of fork links to each other with chute, there is slide block the lower end that is fixed on the just groove joystick of wheelchair armrest, be arranged in the chute, just there is slide block the lower end of groove joystick, be arranged in the slide block, just on the groove joystick handle localizer arranged, there is the handle locating slot side of handrail, below just groove, colluding bedpan with pin, depressing or mention handle, is fulcrum with the boatswain chair, is lever with the fork, then can the lifting bedpan, the stationarity of finding this up-down mode by trial-production is not strong, and bedpan can only be in horizontal direction, and female patients is had many inconvenience.

For addressing the above problem, this utility model provides a kind of improved multifunctional wheelchair, and it is sat, the conversion of clinostatism can not produce oil leakage phenomenon, the lifting of bedpan is more steady, can also make bedpan be in low position, preceding high back by patient's deadweight, more convenient women uses.

For achieving the above object, the technical scheme that this utility model adopted is:

Multifunctional wheelchair is made up of by face, seat face, backrest face, handrail and the universal wheel that is fixed on the wheelchair shelf wheel, lower limb, the backrest face passes through crank, connecting rod, links to each other by face with lower limb in flakes, all these connecting portions all adopt rotating connected mode, on the bottom girder of wheelchair shelf, fixing a small-sized jack, the top of jack has top slider support plate to be supported on the backrest face, the operating grip of jack stand places handrail one side, the joystick of whereabouts be placed on jack below.Thisly utilize that jack is realized sitting, the clinostatism conversion, operate more steadily, avoided the oil leakage phenomenon of original hydraulic structure, eliminated unsafe factor, and simplified processing technology, help suitability for industrialized production.

This multifunctional wheelchair, its seats face be by being with just seat, hole face and stool handhole cover door face to form, and stool handhole cover door face slideway arranged below the stool handhole cover door face, and the stool handhole cover door face can be removed along this slideway, and just groove is positioned at and is with just face below in seat, hole to link to each other with just groove support by pin; Just the groove support comprises gear, tooth bar and fairlead, and tooth bar is positioned at fairlead inside, and gear, tooth bar engagement by steerage gear, drive tooth bar, thereby realize the lifting of bedpan.Because bedpan is connected with just groove support by pin, bedpan can hypsokinesis under the effect of human body self weight, before promptly being in high after low position, more suitable with the physiological make-up of women's Excretory organ.

The wheelchair pedal is made of left and right sides two parts, and each part pedal is a reversible, and the one side of pedal can be a massage face.Wheelchair can have the rain cover of screening or awning.

Can realize seat, clinostatism conversion steadily owing to adopted technique scheme, this utility model not only to have, advantages such as self-care defecation, make that also the technology of making is easier, can directly select some standard components for use, help suitability for industrialized production, safety simultaneously is higher.

Below in conjunction with accompanying drawing this practical work one is described in detail:

Fig. 1 is the front view of wheelchair;

Fig. 2 is the vertical view of wheelchair.

Multifunctional wheelchair as shown in Figure 1, form by face, seat face, backrest face, handrail and the universal wheel that is fixed on the wheelchair shelf by wheel, lower limb, the backrest face passes through crank, connecting rod, links to each other by face with lower limb in flakes, all these connecting portions all adopt rotating connected mode, on the bottom girder of wheelchair shelf, fixing a small-sized jack 7, the top of jack 7 has top slider support plate to be supported on the backrest face, the operating grip of jack stand places handrail one side, the joystick of whereabouts be placed on jack below.The seats face is by being with just seat, hole face and stool handhole cover door face to form, and stool handhole cover door face slideway arranged below the stool handhole cover door face, and just groove 5 is positioned at and is with just seat, hole face below, links to each other with just groove support by pin 4; Just the groove support comprises gear 2, tooth bar 9 and fairlead 3, and tooth bar 9 is positioned at fairlead 3 inside, and gear 2, tooth bar 9 engagements by steerage gear 2, drive tooth bar 9, thereby realize the lifting of bedpan 5.Wheelchair pedal 1 is made of left and right sides two parts, and each part pedal 1 is a reversible, and the one side of pedal can be a massage face.Wheelchair can have the rain cover of screening or awning 6.
