Definitions

• This invention relates to a lifting device which is useful for lifting a patient.
• a lifting device useful for lifting a patient is provided with a wheel supported base frame having a guide extending vertically, a carriage guided for vertical movement by the guide, an elevating device coupled between the base frame and carriage to raise or lower the carriage, a mounting plate on the carriage, at least one patient lifting assembly releasably engaging the mounting plate and located laterally outwardly from the mounting plate, one at least of the patient lifting assemblies comprising a suspension bar having on it a plurality of lifting ribs clamped to the bar and slidable along or rotational about the bar, each rib being of such curved shape as to be positionable beneath a patient, and clamp means for clamping each rib to the bar.
• a lifting device for lifting a patient comprises a base frame, wheels supporting the base frame, guide means extending vertically from the base frame, a carriage guided for vertical movement by the guide means, elevating means coupled to the base frame and the carriage operable to raise and lower the carriage, mounting means on the carriage, and at least one patient lifting assembly having mounting engagement means releasably engaging said mounting means, and located laterally outwardly from said mounting means.
• FIG. 1 is a side elevation of a lifting device having a patient lifting assembly comprising a plurality of curved ribs
• FIG. 2 is an end elevation of FIG. 1, a reclined position, and it is an object of the invention to provide means which will achieve all the above identified desiderata.
• a lifting device useful for lifting a patient is provided with a wheel supported base frame having a guide extending vertically, a carriage guided for vertical movement by the guide, an elevating device coupled between the base frame and carriage to raise or lower the carriage, a mounting plate on the carriage, at least one patient lifting assembly releasably engaging the mounting plate and located laterally outwardly from the mounting plate, one at least of the patient lifting assemblies comprising a suspension bar having on it a plurality of lifting ribs clamped to the bar and slidable along or rotational about the bar, each rib being of such curved shape as to be positionable beneath a patient, and clamp means for clamping each rib to the bar.
• a lifting device for lifting a patient comprises a base frame, wheels supporting the base frame, guide means extending vertically from the base f ame, a carriage guided for vertical movement by the guide means, elevating means coupled to the base frame and the carriage operable to raise and lower the carriage, mounting means on the carriage, and at least one patient lifting assembly having mounting engagement means releasably engaging said mounting means, and located laterally outwardly from said mounting means.
• FIG. 1 is a side elevation of a lifting device having a patient lifting assembly comprising a plurality of curved ribs
• FIG. 2 is an end elevation of FIG. 1
• FIG. 3 is an enlarged side elevation illustrating a mounting member extension such as is used in FIGS. 1, 2 and 6 hereof,
• FIG. 4 is a perspective view showing the manner in which the curved lifting ribs of FIGS. 1 and 2 are positionable beneath a patient
• FIG. 5 is a similar perspective view showing a patient being lifted in a reclined position by lifting ribs
• FIG. 6 is a fragmentary section through the suspension bar of FIG. 5 showing the clamping means
• FIG. 7 shows an alternative patient lifting assembly which comprises a seat frame assembly
• FIG. 8 is a staggered fragmentary cross-section of FIG. 7.
• FIGS. 1, 2 and 3 are drawn in the opposite hand to the remaining figures.
• a lifting device 10 which is useful for lifting a patient, comprises a base frame 11 which is of general U-shape in plan, comprising a bridge portion 12 and two projecting arms 13, all supported by four castor wheels 14.
• the base frame 12 has guide means upstanding therefrom, the guide means comprising a *C section channel 17 having parallel inwardly facing guide surfaces 18 and 19 (FIG. 1), and these are engaged by the wheels 20 of the carriage 21 thereby guiding the carriage for vertical movement.
• the carriage 21 comprises a plate 22 which extends outwardly through the gap 23 of the C- shaped channel 17, and terminates at its outer end in a mounting member 24 which is a second plate facing a patient lifting assembly 25, and the patient lifting assembly 25 is located laterally outwardly from the mounting member 24 by either a mounting bracket 27 (FIGS. 4 and 5), or a combination of a foreshortened mounting bracket 27a and a mounting member extension 28 (FIGS. 1, 2 and 7).
• Lifting means for lifting the carriage 21 may comprise a hydraulic cylinder, but in this embodiment comprises an electrically operable linear actuator 30 which is co-operable between the carriage 21 and base frame 11, and is controlled by a battery switch and relay circuit contained in the casings 31 and 32.
• the mounting member 24 has a rear surface 34 and a front surface 35, and also comprises a plurality of apertures 36 the surfaces of which constitute support surfaces.
• the mounting bracket 27, or alternatively the mounting member extension 28, carries on it a loop 38 which loops over the upper end of the mounting member 24 and bears against the rear surface 34.
• Rearwardly extending pins 39 constitute rearward projections which engage the support surfaces of apertures 36 and inhibit inadvertent release or movement of the patient lifting assembly 25. It is important to provide a patient with a feeling of security, but clearly the projecting lugs and notches could be used in lieu of the pin and aperture arrangement described.
• the patient lifting assembly comprises a suspension bar 42 which is clamped between clamp members 43 (FIG.2) on the outer ends of brackets 27 [or alternatively brackets 27a of FIG. 1 which are of reduced length (when use is made of the mounting member extension 27)].
• the suspension bar carries on it a plurality of resilient lifting ribs 45, each lifting rib 45 terminating at its upper end in releasable clamp means 46 (FIG.6), the releasable clamp means 46 comprising a loop end 47 of a respective lifting rib 45 connected back to the lifting rib 45 by means of a tension pin 48, and clamped by a clamping cam 49 which swivels about a pin 50 when a clamping lever 51 is actuated.
• releasable clamp means 46 comprising a loop end 47 of a respective lifting rib 45 connected back to the lifting rib 45 by means of a tension pin 48, and clamped by a clamping cam 49 which swivels about a pin 50 when a clamping lever 51 is actuated.
• each lifting rib 45 is of such curved device which can be used by one nurse without further assistance; the device can be wheeled through a doorway, and can be used to lower a patient into a bath; the spring lifting forks apply pressures which are so nearly even that there is little danger of discomfort to a patient; each fork can be individually retracted, and all this can occur not only without discomfort to the patient but also under circumstances wherein the patient can feel very safe.
