The PLC type (Personal Length Combination)

In healthcare institutions often the situation arises when residents need to share the same toilet. One tries (possibly with or without assistance) to stand up in every possible way. For one the bowl is too high or too low. For the other the wall grip is too high or too low.

A rather high bowl is the best option for standing up with the least effort. However, a high bowl is counterproductive due to loss of energy, thus increasing the chance of constipation and risks such as a CVA. During bowel movement, the pelvis should be tilted properly backwards. The lower your sitting position, the easier bowel movement is and the less cardiovascular pressure (pushing) is being exerted. But a ’deep’ position also means that standing up is difficult.

The solution for imitating this natural motion of sitting down and standing up is provided by the Aerolet toilet lift type PLC for intramural care. This allows different users to activate their personal lift height by themselves by using a control panel with five stand-up options with coloured lights support. In particular, the lower leg length is important, so that the feet remain in contact with the floor.

The individual variation is a result of two main issues:

♦ the degree to which the tilting of the trunk varies; there appears to be
connection with a person’s stature: heavier persons move down lower to
obtain more compensation through the centre of gravity. By leaning the
trunk forward, the centre of gravity is placed above the feet. As a result,
the moment on the knee joint is reduced.
♦ the connection with the starting position of the lower leg in relation to the
sitting height: short legs remain upright, whereas long legs have been
tilted in order to sit down.

This Aerolet toilet lift type PLC is also beneficial to care providers. No longer having to provide assistance when standing up will certainly be perceived as less physical load. Vice versa, the users of the lift will feel less hurried by a carer waiting at the other side of the door.

Able-bodied persons experience no inconvenience whatsoever from this Aerolet toilet lift, as long as the toilet seat remains in its lowest position.
