Hydropneumatics for the Wellbeing of Patients

BLOC-O-LIFT applications in functional operating tables
Gas springs provide exceptional mobility in medical technology equipment

Gas springs from STABILUS have become a staple in medical and rehab technology. Whether it is hospital beds, wheelchairs, or walkers – gas springs support the lifting and lowering, changing or adjusting of movable design elements safely and comfortably. The BLOC-O-LIFT and the special HYDRO-LIFT type gas spring play a central role

Koblenz, October 2007. - Day and night, the gas springs from STABILUS are making life a little bit easier for patients and nursing staff. Maintenance-free, silent, and extremely reliable – that’s how they have been serving medical and rehab technology for years. When it comes to functionality and quality, gas springs from the BLOC-O-LIFT series set standards – for example in highly functional operating tables or mobile walking aids.

As a rule, BLOC-O-LIFT products are locking gas springs. Thanks to their clever piston-valve system, these gas springs assume the adjustment function (with force support) and variable locking. This locking can be to-the-point accurate (rigid) or softly spring-loaded. Even in its standard version, this gas spring covers a broad spectrum of medical technology applications. In massaging tables, brackets, and scooters, it is often part of the standard equipment.

Two special variants of this gas spring family are BLOC-O-LIFT OR and BLOC-O-LIFT OBT. The OR version has an additional override function, which protects the application from overload, both in tension and compression direction. A very typical application for this gas spring is its use as a movable, adjustable connecting element in head and foot panels of treatment tables or hospital beds. The OBT model (Over Bed Table), on the other hand, is used mainly in patients’ nightstands, where it allows for variable height adjustment with rigid and spring-loaded locking in the compression direction. The upward movement of the table does not require an actuation mechanism. This combination of different functions makes using the table comfortable for the patient; at the same time, it allows fast lifting of the table top by medical staff – for example in emergencies.

Another – quite self-contained – product in this gas spring series is the BLOC-O-LIFT column. This is a self-supporting gas spring for comfortable height adjustment by foot pedal (both hands remain free). This column is installed primarily in physician’s chairs.

Progressive Wherever You Go

By now, the HYDRO-LIFT gas spring is well established in medical and rehab technology. It is part of the non-locking gas springs of the LIFT-O-MAT series from STABILUS; they are usually used when movable elements must be lifted or lowered into defined positions. Besides force support, a piston package with a valve closing mechanism in this device allows variable positioning over the entire control range or even in partial ranges of the stroke. It can be fixed without an actuation mechanism.

Typical applications for the HYDRO-LIFT are progressive incline adjustment of foot panels in hospital beds or variable adjustment of monitor brackets. One of the special features of the HYDRO-LIFT gas spring is its ability to absorb large weight fluctuations within certain limits.

Both the locking BLOC-O-LIFT gas spring and the non-locking HYDRO-LIFT types are easy to install and integrate into the intended design. Like all hydropneumatic products from STABILUS, these are quality products manufactured under conditions compliant with DIN EN ISO 9001, the global standard ISO/TS 16949, and EMAS environmental requirements. At this year’s Medica (Nov. 14-17, 2007), hall 14, booth E19, in Düsseldorf, STABILUS will present additional solutions for medical and rehab technology.
