DE20303002U1 - Patient lift has an adjustable seat and a rolling belt in connection with a lift which moves patients in an ergonomic fashion - Google Patents

Abstract

The patient lift has an adjustable seat (10) and a rolling belt in connection with a lift (9) which moves patients in an ergonomic fashion. The height (8) and depth of the adjustable knee supports (7) make for secure leg support. The rotation point of the lift strut (6) is formed so that a low construction is enabled.

Description

Mobile patient lifting and transfer lift

The invention relates to lifting devices for insecure or disabled persons who are transferred from a sitting to a generally standing position.

Lifting devices of this type preferably consist of a Chassis with lift mast, on which usually at least one boom

is movably mounted.

Mostly a knee mount is used on the mast to support the Knee attached. Lifting devices that follow this principle are available in several Versions known. However, they mainly have the disadvantage that the desired Direction of the tensile forces, especially steeply upwards, not or only

difficult to adapt to different people.

The ergonomic standing up movement is rarely understandable. Since the pulling direction is not flexible, the lifting process is often referred to as

perceived as unpleasant.

The object of the invention is to create a lifting device that meets the ergonomics of the patient.

Two separately controllable linear drives make it possible to To achieve a standing curve that corresponds to the normal standing movement

equals.

To avoid belt pressure under the armpits, Load-bearing device a padded, adjustable back strap

used.

The footrest is rigid, the knee supports are adjustable in height and depth

adjustable to optimally absorb the counter pressure.

Since the position of the shinbone changes when you stand upright , the knee supports have a joint to compensate for this change in movement.

The boom unit has an adjustment drive to tighten the belt after it has been put on and to secure the patient's knees in the knee supports.

The person is now lifted using the lifting drive. Preferably, the position just before the standing position is used to transfer the patient.

The adjustment drive can also be used to optimally adjust the angle between the attached load and the raised boom.

The device is controlled via a hand control with four functions.

The power supply is provided by a removable battery unit with

control box.

An EMERGENCY STOP switch and an electrical emergency lowering

guarantee safe operation.

DESCRIPTION

The uprighting and transfer lift, equipped with a removable battery system (13), is activated by means of a manual control (11) via a multi-channel control box (12).

The functions of the lifting drive (9) for the lifting movement and the adjustment drive (10) can be controlled separately.

Overcurrent detection switches the drives in the end positions

-The device is shown in Figure 1. -The device is moved towards the seated patient.

The patient’s feet are placed on the footrest (3).

The knee supports (7) are then adjusted in height (8) and depth (18) so that the shins rest against the knee and the tip of the knee protrudes over the edge of the knee support.

Now the adjustment drive (10) is extended so that the attached back strap (20) can be easily hooked into the back strap attachments (16).

A chest pad (15) is located between the back strap attachments (16) to prevent injuries if the patient falls over.

Now the adjustment drive (10) is retracted, tightening the back strap (20) and securing the shins in the knee supports (7).

-An illustrative example is shown in Figure 2. -

The person is now lifted using the lifting drive (9). Preferably, the position just before the standing position is used to transfer the person. -This position is shown in Figure 3-

For passenger transfer, the device has two ergonomically arranged push handles (14).

To secure the device, the rear castors (4) are equipped with brakes.

After the transfer process has been completed, the person is lowered onto an appropriate seat by means of a linear drive (9) and the adjustment drive (10) is extended so that the back strap can be unhooked and removed again.

To easily disassemble the device, the double tube lift column (6) is pulled out of the chassis after the lift column locks have been released.

The complete knee support unit can be dismantled just as easily.

Fig 1 shows the device from the side with all described components.

Fig 2 shows the device with a seated person and the back belt (20) fastened.

Fig 3 shows the device with a person standing in order to be able to perform a transfer.

Claims (4)

1. Mobile patient uprighting and transfer lift, characterized in that an adjustable boom ( 10 ) with back strap ( 20 ) in conjunction with a lifting device ( 9 ) enables ergonomic uprighting. 2. MPAU according to claim 1, characterized in that movable knee supports ( 7 ) adjustable in height ( 8 ) and depth ( 18 ) ensure secure leg counterpressure. 3. MPAU characterized in that the pivot point of the boom is arranged behind the vertical of the lift column ( 6 ) and thus a low construction is possible. 4. MPAU characterized in that the rigid, very low chassis ( 1 ) with footrest ( 3 ) can be used at almost all patient transfer points.
