“…An instrumented articulated anthropometric phantom (Patent IPC 94928968.0) developed and validated to simulate the loading conditions of an older adult sitting, semirecumbent, or lying on a pressure-relieving surface (Bain et al 1999) was used as the 'subject' (Figure 1). The phantom has simulated soft body 'tissues' in the gluteal and sacral areas and consists of an articulated body-shell, segmented into head, torso, upper legs (joined) and lower legs.…”

Effects of absorbent incontinence pads on pressure management mattresses Aim. The aim of this paper is to report a study to determine the effects of absorbent pads on the pressure-relieving properties of 'standard' and pressure management mattresses. Background. Pressure ulcers and incontinence often co-exist. There is a strong association between poor mobility and continence problems and patients using pressure management products are therefore also likely to be using absorbent pads.Methods. An instrumented articulated anthropometric phantom with simulated soft body 'tissues' in the gluteal and sacral areas was used as the 'subject'. The phantom was raised and lowered on to three mattresses (standard foam, viscoelastic foam and surface-cut foam) in three states: naked, wearing a dry pad (Tena Super, SCA Hygiene AB) and wearing a wet pad. The pressure mapping device Xsensor was used to record the distribution of pressure over the sacral and ischial areas of the phantom. Peak pressure was used as the primary outcome variable and 10 repeats were made on each mattress under each condition.Results. There were substantial and significant differences for all three mattresses in recorded peak pressures between the naked buttocks and the buttocks wearing a dry pad. There were no significant differences between measurements made using the dry vs. wet pad. Peak pressures frequently occurred over areas of pad folds. Additional testing showed that pads that were 'smoothed' by hand had significantly lower peak pressures than 'unsmoothed' pads. Conclusions. Absorbent pads have a substantial adverse effect on the pressure redistribution properties of mattresses. Pad folds appear to contribute to this effect, which can be ameliorated slightly by smoothing. Absorbent pad manufacturers should consider engineering pads that minimize disruption to pressure management. Further examination of continence and pressure management products is necessary to establish optimum combinations for nursing care.

“…Pressure profile results from these models in comparison with a wheelchair without any cushion, can be seen in Table 2, (Anand, Wood, & McArdle, 2015). (Siekman, Axelson, Noon, Folkedal, & Wisnia, 1998), (Reddy, Patel, Cochran, & Brunski, 1982), (Bain, Scales, & Nicholson, 1999) and (ISO, 2007). The RCLI described in International Organisation for Standardisation (ISO) 16840-2, (ISO, 2007) and (BS ISO, 2007) is a simple representation of the human buttocks, which can be produced in both solid and hollow forms.…”

Polyurethane (PU) foam is one of the most common materials used in the development of pressure relieving cushions. However, it suffers from reduced efficiency in terms of thermophysiological comfort, cost, recycling and importantly, creating a suitable environment for the prevention of pressure ulcers. The paper presents research carried out at the University of Bolton, in the development of pressure relieving cushion applications using three-dimensional (3D) warp knitted spacer fabrics. This research includes the development of a novel technique for measuring pressure distribution while under simulated loading conditions.Using this system, novel and smart 3D knitted spacer cushions were developed, with the following features:1. A shaped/contoured surface was able to redistribute high pressure points normally located in vulnerable areas of an immobile and seated person.2. Peak pressures were reduced and distributed evenly over a much larger area of the cushion than PU foam 3. They are well-ventilated, comfortable, washable and non-flammable and can be easily recycled.
