Abstract

A hospital transfer trolley comprises a main frame from which two parallel end pieces extend at right angles so that a bed, trolley or the like can be received between the end pieces. A pair of horizontal lift members are carried by the end pieces and can be raised or lowered with respect to the end pieces. A couch including a mattress and a mattress support is movable between a horizontal patient-supporting position in which it is between the end pieces and an upright inoperative position on the main frame. The mattress support is engageable with the lift members when the couch is in its patient supporting position to enable the couch to be raised and lowered.

Claims

1. A wheeled hospital transfer trolley comprising a long side piece and two parallel end pieces extending horizontally at right angles to the long side piece and pivotally secured thereto on a vertical pivot so that a patient-transfer vehicle can be received between the end pieces, vertically reciprocable individually operable lift member mounted on each of the end pieces, a patient-supporting bed member mounted on the frame and movable between a horizontal patient-supporting position between the end pieces and an upright inoperative position on the frame, and a bed member patient support means engageable with the lift members when the bed is in its patient supporting position to enable the bed member to be selectively raised or lowered or tilted.

2. A trolley as claimed in claim 1, wherein the patient support member is provided at each end thereof with an extension normally contained within the support member but which can be extended lengthwise of the mattress to engage the adjacent lift member whereby the bed member can be raised, lowered or tilted.

3. A hospital vehicle as in claim 1 wherein each end piece includes a track member on the opposing faces thereof, and the support member is provided with track engaging elements on the underside thereof.

4. A hospital vehicle as in claim 3 wherein the track engaging elements comprise at least one wheel at each end of the support member.
