DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention relates to an aid to the handling of humans and animals (hereinafter referred to as "patients"), whether alive or deceased. In particular, the invention relates to a handling device for aiding the transfer of a patient from one support surface to another, as from a hospital bed or other supporting surface to a patient transfer trolley, and from a patient transfer trolley to an operating table, hospital bed or other supporting surface.
The transfer of patients to various locations in hospitals, mortuaries and like establishments presents difficulties. It is common practice for patients to be transferred on patient transfer trolleys which can be manually propelled from one location to another. Usually, a patient is manually lifted onto and from the trolley by several hospital attendants. In manually lifting the patient, the hospital attendants are exposed to risk of injury. In addition, the patient is also exposed to risk of injury when being manhandled.
The present invention seeks to provide a handling device for aiding the transfer of a patient from one support surface to another.


SUMMARY OF THE INVENTION

In one form the invention resides in a handling device for aiding patient transfer between two support surfaces when such surfaces are positioned adjacent one another, said handling device comprising a body having a transfer surface, the body being attached or attachable to an apparatus providing one of the support surfaces, the body being movable whereby it can assume first and second positions wherein in the first position the transfer surface bridges said support surfaces and wherein in the second position the body extends upwardly of said one support surface to provide a safety barrier therefor.
In another form the invention resides in a patient transfer trolley comprising a wheeled frame carrying a patient support surface and a device for aiding transfer of a patient between said patient support surface and a further support surface which in use is located adjacent said patient support surface, characterised in that the handling device comprises a body having a transfer surface, the body being movable whereby it can assume first and second positions, wherein in the first position the transfer surface provides a bridge between said patient support surface and said further support surface and wherein said second position the body extends upwardly of the patient support surface to provide a safety barrier therefor.
The patient transfer trolley may for example be a trolley intended exclusively for transferring patients on a wheeled bed capable of being used as a trolley (commonly referred to as a trolley bed).
Preferably, the body is capable of assuming a third position in which it is clear of the first and second positions so as to not obstruct access to the patient supporting surface. For preference, the third position is located substantially below the patient supporting surface.
Preferably, the body is mounted on track means having a vertical track section and an inclined track section extending downwardly and inwardly from the upper end of the vertical track section, wherein the body is received in and extends upwardly of the vertical track section when in the second position and wherein the body is received in the inclined track section when in the third position.
Preferably, at least part of the transfer surface is defined by a plurality of elongated rollers disposed longitudinally of the patient support surface.
Preferably, at least part of the patient support surface is defined by a plurality of further elongated rollers disposed longitudinally of the patient support surface.
