DE102004007866A1 - Trolley for lifting and transporting patients on chairs has a servo operated hoist with tilt facility - Google Patents

Abstract

A trolley for lifting and transporting patients, e.g. elderly people, while seated on chairs, commodes or other equipment, has support rails (12) which are positioned under the chair and a servo powered lifting mechanism to raise the chair and occupant. A rearwards tilting action ensures a safe lifting action. The selected position is secured by a safety lock. Different designs of chair can be easily accommodated by inserting adaptor frames.

Description

The The invention relates to a lifting and transfer device for chairs - in particular Care shower and toilet chairs for disabled people People.

hoists on care chairs So far, they have been adapted to the devices in a corresponding design and work either hydraulically or electromechanically.

Caring chairs on working height to bring and possibly tilt to the rear - allow the nursing staff a power-saving Cleaning and care of the patients.

The Most facilities such as nursing homes, clinics, sheltered workshops, etc. have simple Toilet or shower chairs.

task The invention is to use the existing chairs for the optimal transfer process to be able to.

There it chairs of the most varied design, was a model and construction type adapted attachment adapter designed for a secure fixation to enable and to give away no useful lift.

Of the Lifting frame is designed so narrow that it under (almost) every chair fits.

During the booting up the chair unit, the lifting frame tilts backwards to put the patient in a comfortable position.

to Chair lock during the transfer and care of the lifting frame has a rear support with adjustable holders.

Plug-In push rod linkage allow one easy handling whereby the middle zone deliberately designed as open space is to provide the patient in the care position as optimally as possible to be able to.

There All mechanical components are made in stainless steel is a Use also in the shower possible. The electrical components are basically designed in splash-proof design.

Provided he'll be taking care chair transporter over a 24V = exchangeable battery system with manual control.

The Control box contains an emergency stop switch, an electric emergency lowering, as well as a Control display for capacity monitoring of the accumulator.

The one with a Wechselakkusystem ( 6 ) equipped care chair transporter is operated by hand ( 9 ) via a control box ( 6 ) is activated.

The function of the linear actuator ( 5 ) is infinitely controllable.

The device is in - 1 - shown.

Of the Carer transporter is under the chair to be lifted from behind hazards.

For use under certain care chairs, an attachment adapter ( 14 ) in the push-in tabs ( 13 ) of the lifting frame ( 2 ).

Now the adjustable holders ( 7 ) pushed around the backrest tubes and thus fixed and secured the chair unit.

Now the patient with care chair can be raised continuously. - ( 2 -) For easy transfer between two points of application, lifting by about 10 cm is sufficient.

When used for patient care, the linear actuator ( 5 ) to the upper end position.

In this position, the lifting frame tilts ( 2 ) to the rear.

A Mechanics with a so-called asynchronous parallelogram (10 + 11) makes this movement possible.

To secure the unit at the place of use, the rear castors ( 4 ) braked.

After patient care, the lifting frame ( 2 ) shut down to normal transfer height and pushed the device to the next location.

The plug-in push rod ( 8th ) make easy maneuvering possible.

The chassis ( 1 ) with the small front wheels ( 3 ) also allows driving under chairs with crossbars.

Claims (4)

Carer transporter characterized in that chairs can be raised and transferred in particular care chairs with patients. Carer transporter according to claim 1 characterized that while The chair is tilted backward when lifting. Carer transporter according to claim 1 + 2, characterized in that by means of adjustable holder ( 7 ) a fixation and securing the nursing chair is possible. Carer transporter according to claim 1 - 3, characterized in that various attachment adapters ( 14 ) allows the admission of different chair types.
