Description

Hydraulic multi-function patient walking aid

The technical field rehabilitation device.

The existing hanging walking aid that helps the lower limb patient to carry out reconditioning of background technology is made up of wheeled suspension bracket and suspender belt.Patient is in half outstanding state with its walk help, and comfortableness is poor; Play pendulum in walking aid and the walk help about the patient, use inconvenience; Can only be used for walk help, function singleness; The walking aid column not only influences the patient visual field, and causes a kind of limiting to enclose sense to patient.

Chinese patent application number is 2004201217421 the multi-functional patient's walking aid of semi-mechanization, has solved these technical problems substantially; But drive to support the hand winch of patient's device, limit to because of being subjected to the installation site, driving laborsaving and quick rise can not get both, and caregiver is squatted down and shaken capstan winch and can not hold up and protect patient's upper limb, and the problem that the walking aid column influences patient's sight line and mood is failed solution.

The summary of the invention the technical problems to be solved in the utility model is: drive with hydraulic technique and support patient's device; Caregiver is handled walking aid with foot and is risen, and frees hand to hold up protect patient; The above space of patient's two axils does not have the walking aid member, and broad view does not have the walking aid member to limit and encloses sense; Make walking aid convenient and cosily support patient walk training, go to toilet, with regard to chair, wheelchair, bunk bed up and down.

The technical scheme that solves this technical problem is: have at two T-shaped joint places of H shape base [2] (referring to accompanying drawing) two can stepless lifting three joint bushing type columns [3], two columns [3] top connects with waist frame beam [13].The scissors-type lifting [14] that promotes with oil cylinder [15] is housed between the crossbeam of base [2] and the waist frame beam [13].Oil cylinder [15] is an internally installed pull-spring oil return self-resetting oil cylinder.A foot-operated hydraulic oil pump [16] is adorned on two T-shaped joint places of base [2] or a left side or the right side, is connected with oil cylinder [15] with oil pipe.Base has four road wheels [1] for [2] four jiaos, and preceding two is universal wheel, and back two is the wheel of keeping straight on, and the four lines travelling wheel is manual locking separately all.

Waist frame beam [13] both ends horizontal is being welded waist frame arm [4], adorns the vertical unthreaded hole of armpit support arm [7] in addition, and respectively there is a ring two waist frame arms [4] termination, in wear belt [5].Play on the belt kicking strap [6] of decussate, two front ends are fixed on the belt [5]; Respectively there is a button two rear ends, and belt [5] therefrom passes, and fastens after one's death patient.Waist frame beam [13] and waist frame arm [4] are surrounded by flexible sheath.

Two armpit support arms [7] are arc, and there is screw thread the lower end, insert in the vertical unthreaded hole of waist frame beam [13], with locknut [12] locking; There is vertical threaded bore the upper end, screws in the screw rod [10] of installing and regulating ingot holder [11] height in it, and locks with locknut [9].Two armpit support arms [7] can be moving in the vertical unthreaded hole transfer of waist frame beam [13], adapts to patient's chest breadth with the inner width of regulating the two, and respectively there is a ring below, two armpit support arms [7] upper end, in wear the pectoral girdle of fastening after one's death from patient [8].

Start foot-operated hydraulic pump [16], should close its gate gurgle valve with hands earlier, the reuse foot is stepped on the pedal of hydraulic pump repeatedly, and the oil that pump carries in the fuel tank is compressed into oil cylinder [15] through oil pipe, oil cylinder promotes waist frame beam [13] through scissors-type lifting [14], and two waist frame arms [4] and two armpit support arms [7] are boosted thereupon.Shift onto when desiring to reach the position when the two and to stop stepping on, the two just rests on this place.Otherwise, open the gate gurgle valve of hydraulic pump [16], oil under the main effect of the internally installed pull-spring of oil cylinder [15] and waist frame beam [13] connect under the assosting effect of all weight and patient's part body weight and push back in the fuel tank of hydraulic pump [16], two waist frame arms [4] and two armpit support arms [7] are fallen thereupon.Set up the reduction of speed of relief valve aperture and shut-in time may command two waist frame arms [4], two armpit support arms [7] and fall off-position and put.

Before using walking aid, rotate two armpit support arms [7] according to patient's chest breadth earlier, make its inner width just in time allow ingot holder [11] be positioned at the patient oxter, locking locknut [12].Set up ingot holder [11] more highly: first rising waist frame arm [4], make patient when sitting posture, waist frame arm [4] just in time is in patient's waistline; Rotate ingot holder [11] again, make it when the patient oxter, patient's two elbows just in time are supported on the waist frame arm plane, locking locknut [9].

During last this walking aid of patient, before the nursing staff is pushed into bed that patient sits, chair, wheelchair with it, and at the bottom of H shape base [2] is stretched into bed or stretch at chair, wheelchair two rear flank, lock line travelling wheel [1].People's two upper limb upper arm make its oxter frame in ingot holder [11] in spite of illness.Fasten pectoral girdle [8], start foot-operated hydraulic pump [16], make the rise of waist frame arm [4] and armpit support arm [7], and be parked in suitable height, with patient's upright degree of being just.Kicking strap [6] is risen through lower limb fork buttocks pocket, make thereafter that the button at two ends is through on the belt [5], fasten belt.Unclasping road wheel [1] uses.Kicking strap [6], the visual lower limb state of an illness of belt [5] are used.During following walking aid, program is opposite.

When patient does walking and takes exercise, two axils are supported by ingot holder [11], have alleviated upper limb, the trunk load to lower limb, have the flexibility of pectoral girdle [8] and belt [5] to go along with sb. to guard him again, and assurance health standing position is not waved; Walking aid moved with health when patient walked, as assisting in about two people.Two universal wheels in front can make the flexible optional turning of walking aid.

When patient went to toilet, walking aid was held up and is protected patient to toilet, the caregiver retinue.Walk to toilet seat, fall back, make H shape base [2] surround toilet seat.Lock line travelling wheel [1] is fallen two waist frame arms [4] and two armpit support arms [7], and caregiver is untied belt [5], holds up protect patient and be sitting on the toilet seat.Pectoral girdle [8] is untied as required or is not untied.Go up walking aid after an action of the bowels again.

Patient's bunk bed, seat, wheelchair, program is with toilet seat in place.

Appended drawings is a hydraulic multi-function patient walking aid structure principle chart.
