Abstract

The utility model relates to a medical nursing crane, which belongs to the application technical field of medical nursing appliances. The medical nursing crane is composed of a truckle, a bottom rack, an erecting rod, a lifting rod, a rocking handle assembly, a cushion, etc. The lifting and lowering of a patient is completed by the process that an operator rocks the a rocking handle to drive a lead screw nut structure via the meshing of a cone gear, and the movement of the lead screw drives the lifting rod to move up and down. The medical nursing crane is used for completing the shifting nursing from a bed to a wheelchair, etc. of a patient who is inconvenient to move with lower limbs. The utility model can decrease the strength of nursing and increases security.

Description

Medical nursing hoist

This utility model belongs to medical treatment and nursing apparatus applied technical field.

The lower limb disabled person, paralytic patient and action inconvenient old people's ward nursing and the displacement in the home care (it is first-class for example patient to be moved on to wheelchair from the bed) they are a gruelling job, misoperation also may cause patient's damage once more.By means of the medical nursing crane nursing staff is sling the patient from the bed like a cork, be put into places such as wheelchair safely and reliably and go.

The purpose of this utility model is: design and a kind ofly specialize in crane that medical treatment and nursing uses to help the nursing staff laborsaving and finish lower limb function forfeiture patient's displacement safely.

This utility model adopts castor to be installed in below the underframe, and vertical rod is welded on the centre of underframe.Playing suspension rod is that hinge is connected with an end of vertical rod.Medicated cushion has been articulated in the other end of suspension rod with handle.One conical gear is installed in woodruff key and nut on the crank shaft that welds together with rocking handle, and crank shaft is assemblied in screw with two rolling bearings again and is packed on the cover plate on the casing.One end of leading screw is connected with a suspension rod hinge, and the other end becomes cylinder and ut socket inwall to be slidingly matched.The threaded portion of leading screw constitutes screw-nut structure with the nut that is welded on ut socket one end.

Ut socket is assemblied in a side of casing with rolling bearing, and its axle head assembles a conical gear with woodruff key and nut.This gear is meshed with conical gear on being installed in crank shaft.Back prop is welded on the opposite side of casing, and it is connected with hinge with vertical rod.

This medical nursing crane is simple in structure, finishes driving and self-locking simultaneously with screw-nut structure, and avoid the hydraulic structure of existing medical crane, thereby greatly reduced cost, be a kind of medical nursing crane that is very suitable for popularizing.

Below in conjunction with Figure of description one routine this utility model most preferred embodiment is described.

Weld with round steel pipe underframe of making (4) and the vertical rod (2) of making, and castor (5) is installed in underframe (4) last (as shown in Figure 1) with round steel pipe.One end of vertical rod (2) and burn-on with the end that plays suspension rod (1) that round steel pipe is made that (Fig. 3 Fig. 4) passes with pin and constitutes hinge and connect (as shown in Figure 1) hinge head then

One end of back prop (8) is a hinge head, and it is connected with vertical rod (2) hinge, and the other end is welded on casing (9) and goes up (as shown in Figure 2).Bearing bracket stand (16) is welded in respectively on casing (9) and the cover plate (10) with lid bearing bracket stand (21), and respectively crank shaft (23) ut socket (17) is passed through four rolling bearings (14), (15), (22), (24) are assemblied in casing (9) and cover plate (10) last (as shown in Figure 2).Cover plate (10) is assemblied on the casing (9) with bolt (27).Two conical gears (13) and (20) are set on ut socket (17) and the crank shaft (23), with woodruff key (24) (28) location, with nut (11) (12) locking.These two gears are in normal engagement (as shown in Figure 2).A cylindrical end of leading screw (18) and the inwall of ut socket (17) constitute movingly, and the other end is that hinge head is connected with suspension rod (a 1) hinge.The screw thread of leading screw partly constitutes screw-nut structure, (as Fig. 1, shown in Figure 2) with the nut (19) that is welded on the ut socket (17).

Use artificial leather, materials such as sponge are made medicated cushion of the present utility model (7), and have been articulated to suspension rod (1) last (as shown in Figure 1) with handle (6).

When the care-giver shakes the rocking handle (26) that welds together with crank shaft (23), by woodruff key (25), the location of (28), gear (13), the engagement of (20) drives ut socket (17) thereby rotation is moved leading screw (18).Leading screw (18) moved through suspension rod (1), handle (6) moves up and down the patient who is sitting in the medicated cushion (7), thereby finishes the nursery work of slinging and putting down to the patient.

The handrail that the care-giver can select on the bar (2) is shifted crane onto mobile destination, slings or puts down the patient by shaking rocking handle (26), finishes lower limb function forfeiture patient's displacement nursing.
