Patient comfort

Patient surface ergonomics

The ergonomic division of the patient surface helps prevent pressure. The dimensions of the 4-part patient surface of wissner-bosserhoff nursing beds are based on findings from anthropometrics, i.e. on the average size and height of a person. On the basis of professor Eigler’s* findings, it can be seen that the backrest area should be at least 80cm long in order to effectively support the cervical spine. The bed can be extended to 220cm to help prevent the patients feet from touching the footboard.

Toes/ feet touching the footboard will often cause pressure ulcers.


2 automatic positions

The automatic positions of Sentida, adjustable at the push of a button, increase comfort when lying in bed and support bedsore prevention for the benefit of the resident while reducing the strain on nursing staff. 

Automatic seating position

The automatic comfort seating brings the bed into a pre-selected seating position for watching TV and reading comfortably, for eating or communicating at eye level. 

Mobilisation using the lifter is effectively supported in this position. In addition, this position facilitates breathing and digestion. It trains spatial orientation and stimulates circulation for residents, confined to bed. The double retraction provides additional relief of pressure in the sacral area. 

Automatic comfort position

The preset legs up position promotes decongestion with venous diseases and at the same time supports bedsore prevention. The 1/2 Fowler 30° position with knee lifting guarantees a reduced bedsore risk* thanks to a favourable weight distribution in the sacral region, which is especially at risk of developing bedsores.

Pressure relief

Benefits of Bi-Netic Double Retraction

 Creates an extra 17cm in the bed

 Excellent for pressure relief and reduces shear forces

 Very comfortable and does not cramp the stomach

 Aids breathing

Double retraction effectively supports OSKA  pressure care mattresses and demonstrates that we should make use of all technical means at hand to improve pressure ulcer prevention.

Fall prevention


Fall prevention system

The siderails can be used in 3 ways depending on the risk assessment of the patient:

fall prevention.jpg

1.  Siderails up
2. Siderails down
3. Head end side rail up only. In the event of a fall, the patient would always slip out feet first and would often be prevented from rolling out of bed completely. This greatly reduces the risk of hip fractures and other injuries.

If a patient is attempting to get out of bed themselves, the elevated siderail at the head end assists them (as a hand rail) further reducing the risk of falling when trying to stand from a low bed.

Systematic fall prevention is of crucial importance in care for the elderly, making it an important quality feature of a nursing home. The consequences of falls are often very serious for elderly people and, in the worst case, even irreversible.

The fear of further falls is one of the most common psychological consequences. With the Sentida range of low nursing beds, wissner-bosserhoff has achieved a consequent and above all uncompromising implementation of the requirements of modern nursing care: maximum safety hand in hand with a cosy design.

The innovative solution such as the patented SafeFree® side guard concept reduces falls, as well as the consequences associated with them.
