Abstract

A portable device (10) for attachment to a lift system consists of a de driven motor and gearbox (11) onto which is mounted a shaft (12) supporting a tape spool (13), a speed governor (14) and one or more load cells (15). The tape drum (13 drives a tape (16) in or out depending on the rotation of the motor (11).The device (10) is attached to a lift system for example an overhead hoist (31) or mobile hoist (40), the device (10) initially lifts the user and measures their weight, the load to be taken by the user is input via a hand set (22) to a controller (20). The user is then allowed to walk supported in part by the device (10). Any small deviations in the load taken up are allowed by the controller (20) but if any large deviations are detected (ie stumbling/falling), then the device 10 takes up the whole weight of the user.

Description

Rehabilitation Device
The present invention relates to a rehabilitation device for use after injury, post trauma recovery and strokes, in particular a device allowing a person to walk while being supported. In circumstances where a person recovering from an injury has to be restored back to health and mobility, the physiotherapists use various known methods depending upon the severity and type of injury. These methods include enabling the person to walk within parallel bars with a physiotherapist or using a physical therapy walker or gently allowing the person to take some of their load on a tilt table, gradually increasing the angle and hence the load. However, such apparatus is usually situated in the physical therapy or rehabilitation departments of hospitals and require the person' s attendance at these departments for their use and therefore are not readily available for use by everyone. The present invention seeks to make improvements. Accordingly, the present invention provides a portable device for attachment to a lift system, the device comprising a power driven flexible load carrier, means to detect the load on the carrier, and control means to control the proportion of a load carried by the carrier. The portable device can be attached to any lift system, for example an overhead hoist system where the device can be used to support a user and allow controlled load bearing by the user or can be used in combination with a mobile hoist, in any location convenient for both the user or the carer. More preferably, the flexible load carrier is controlled to initially support the whole of the weight of the user, and is then controlled to reduce the a proportion of the load carried to allow the user to take a measured load, the detection means monitoring the load taken by the user, such that small deviations in the load measured are allowed but detection of a large deviation results in the load carrier taking up all of the weight of the user as measured previously. The device enables the user to safely take some of their own weight as determined by a physiotherapist or similar expert. Any stumbling (large deviations in load measured) results in all of the load taken up allowing the user to rest or the carer to re-set the percentage of load to be carried by the user. Therefore, the device allows the rehabilitation of personnel anywhere convenient for the user and the carer without risk of the user falling or the carer hurting themselves when trying to support the user, such treatment previously only available using fixed apparatus within rehabilitation centres or departments within hospitals. Preferably, the device is re-activated to take up the load by movement of the load carrier. In a preferred embodiment, the portable device includes a flexible tape wound onto a drum, the shaft of the drum connected to a load cell, the shaft driven by a motor. Preferably, the device is housed within a cassette to be more easily used with overhead gantry systems. The cassette including the tape, drum, load cell and associated power and control means being very compact to allow for portability and greater lifting heights. In another preferred embodiment, the device is used in combination with a mobile hoist, the device incorporated within the mast of the hoist and the flexible carrier extending beyond the mast . The benefit of using the device with a hoist is that the user is supported and enabled to walk longer distances without the constraints of having to go back and forth as under an overhead hoist or gantry system. The invention will now be described by way of examples only, with reference to the accompanying figures in which: - Figure 1 is a schematic view of a device according to the invention; Figure 2 is a schematic view of the device attached to an overhead hoist system; and Figure 3 is a schematic view of the device in combination with a mobile hoist . Referring to Figure 1, the portable device 10 consists of a motor driven tape wound onto a drum with a lifting attachment on one end via a load cell. The device consists of a dc driven motor and gearbox 11 onto which is the shaft 12 supporting the tape spool 13, the speed governor 14 and the load cell 15. The tape drum 13 drives the tape 16 in or out depending on the rotation of the motor 11. The tape 16 is prevented from winding too far in or out by limit switches (not shown) . The speed governor 14 operates by centrifugal force if the motor gearbox 11 fails. The load cell 15 supports the shaft 12 at its furthest end and is calibrated by using a controlled load. The device 10 is controlled by a PLC or PCB 20 or similar. Typically, the device is attached to a lift system and the user is lifted their weight measured by means of the load cell 15. The user is supported by a harness (not shown) and the load imposed by the user through the harness is measured by one or more of the load cells 15. For rehabilitation purposes, the load to be taken by the user is expressed as a percentage of their measured body weight and can be input via a hand set 22 to the PLC or PCB controller. The carer then inputs the load to be taken by the user as either a definite mass or as a percentage of their body weight . This load can be increased or decreased depending upon the user. The user is then allowed to walk taking up the load as input into the device. Small deviations in the load taken up are allowed by the control means but if any large deviations are detected, then the device takes up the whole weight of the user. This is because a large deviation implies a fall or stumble by the user, due to the user finding the percentage of their weight too much to carry, the load cell 15 and PCB 20 recognising the large deviation in load measured operate the tape 16 to take the user's full weight and totally support the user. A lower load bearing value can then be set, by means of the hand set 22. Thus, the user is always supported safely and their load bearing weight adjusted according to their ability. In this way, their progress can be measured, controlled and monitored. Figure 2 shows one preferred embodiment of the device incorporated within a cassette 30 to be easily used with an overhead hoist systems 31 or even a portable gantry system, enabling the users' to be treated in their own homes. Currently, this is not possible as treatment can only be carried out within rehabilitation centres or departments . A further embodiment of the invention is shown in Figure 3, where the device is used in combination with a mobile hoist 40. The preferred hoist is one that does not have a lifting arm in front of the mast, thereby freeing up space where the lifting occurs. The mast 41 also to be of a height that allows the user to use a walking harness if desired. The mobile hoist 40 allows the user to exercise for longer distances without the tedium of going back and forth under an overhead hoist or gantry system. The device can be located on the cross member of the wheeled hoist with a tape from the spool connected to the end of the lifting arm. When the motor and gearbox 11 rotate, tape 16 is wound or unwound which in turn will lift or lower the lifting arm of the hoist 40 about the main pivot point. The device can equally be used in combination with a standing or toileting hoist.
