WO_2023285708_PA

Resumen de: WO2023285708A1

The present invention relates to a pelvic seat or brace that can be thermoformed on the patient (taken as a mould in the seated position), in a way that is comfortable for the patient, avoiding unpleasant sensations and uncomfortable or impossible postures (as the case may be), minimising time spent by therapists carrying out modelling on patients while reducing the number of professionals involved in the production process, at an affordable cost, and which can undergo subsequent thermoforming in order to be readjusted to morphological and/or physiological changes in the patient. The device consists of four main parts: base, column, backrest and abductor block. The modelling and production used to generate the device allow it to be customised to increase accessibility in terms of use and enable small-series production.
