Let’s get it clear: Requirements for belts and harnesses in seating

By Dr Barend ter Haar

What are lap belts for? In wheelchairs, shower chairs, or other seating systems, some are created for restraint in a mishap, some just for security to protect the resident from falling out, and some for postural control (understood as postural assistance devices or PSDs). The design and placing for each of these various functions are different.

Postural assistance gadgets, such as placing supports, have a particular function, which is to support a specific, to help maintain and increase daily functionality for the person, and to secure versus the advancement of skeletal deformities, or to remedy them. These gadgets, with their postural assistance purposes, are not to be puzzled with safety belts and similar devices created to function as vehicular occupant restraints, nor with basic safety belts.

There are instructional annexes on: A. How to measure an individual; B. How to determine a PSD; C. The difficulty relationship between the operability of PSD and physical and/or cognitive mastery level of resident; D. PSD mounting gadgets; E. Prevention of danger of asphyxiation.

Apart from the specified requirements– i.e. the will specs (such as: “Seating wheelchairs and systems shall be supplied with space offered to install PSDs in the positions needed by this British Standard”; “PSDs will be checked in accordance with the tests in ISO 16840-3, and have actually passed the tests”; etc.)– there are commentaries setting the scene for the requirements.

. The PSDs enable the seated person (the occupant) to be positioned to maximize their functional activities in a safe environment. These requirements have a balance of maintenance of posture and of safety. This British Standard has actually been produced for use by clinicians, engineers, carers, occupants, sellers, makers, and repairers.

This brand-new guidance positioned the onus on the maker or equipment prescriber to decide what might be best for a person; although with minimal guidance on how this is to be guaranteed. This introduced the threat of a range of analyses, which may not be constant, and which could trigger more confusion.

These deaths are thought to have happened as an outcome of improper positioning, modification, or failure of the assistances. Users appear to be confused as to finest practice, and the reasons why postural assistances need to be positioned and changed according to the residents requirements.

BS 8625 provides guidance on the advantages and drawbacks connecting to the proper vs inappropriate option and positioning of belts and harnesses, including topics around: restraint vs positioning, security, paediatric positioning, materials, and transport. Particular suggestions is supplied around pelvic positioning, and then trunk, leg, head, wrist and foot assistance.

The MHRA originally provided assistance in the UK on the positioning of pelvic positioning supports, but the advice was in result more proper for wheelchair restrain and occupant restraint systems, rather than placing assistances.

The records of MHRA (Medicines & & Healthcare products Regulatory Agency) show that over the last 15 years there have been 4 reported deaths and 17 serious injuries in the UK involving, or attributed to, failures relating to pelvic posture supports or anterior trunk postural assistance devices.

In BS 8625, clinicians now have access to conclusive information which was formerly missing from the MHRA guidance. Following the requirements within BS 8625 will cause better results, and improved security for medical equipment users.

For this reason, a British Standard, BS 8625 [2], has actually been produced which defines requirements for the choice, placement, and fixation of versatile postural support devices within seating systems and devices, including wheelchairs. Seating postural support gadgets (PSDs) can be included in several scenarios, consisting of static seating, wheelchair seating, shower chairs, and so on
