Abstract:
Bedridden patients with cardiopulmonary diseases,elderly long-term bedridden patients,and certain postoperative patients require elevation of their lower limbs to a position above the heart.Traditionally,this is achieved by placing items such as clothing,blankets,or soft objects like leg pads under the lower limb as cushions.However,this method can lead to uneven force distribution on the patient's legs,potentially causing vascular compression and discomfort.To address these issues,the medical staff of department of brain surgery of the Second People's Hospital of Tongxiang City had developed a multi-functional foot pad device incorporating height adjustment,pressure dispersion,and heating functions,based on biomechanical principles.This device has been granted a National Utility Model Patent of China(patent number:ZL 2021 2 3217248.8).The device consists of a cushion plate,a backing plate,a raised block,a rotating shaft,a fixed shaft,a support frame,a chute,a footrest,a gaiter strap,a connecting belt,an extension plate,a drive motor,and a power cord.It allows for angular adjustments ranging from 15°-45° through the use of a rotating backing plate and a chute-supported frame.The arc-shaped footrest,designed ergonomically,and an intelligent temperature control system enable precise adaptation to individual anatomical characteristics.The usage procedure involves placing the adjustable foot pad on a flat bed,positioning the patient's leg in the footrest,securing it with the gaiter strap,adjusting it to a comfortable height,activating the intelligent temperature control system for heating,and promoting limb blood circulation.This device offers an innovative solution for preventing lower extremity deep vein thrombosis(LE-DVT)by employing a multi-dimensional intervention strategy that combines mechanical prevention with physical therapy effects.The adjustable heating foot pad is easy to operate,provides comfort and convenience,and reduces complications such as LE-DVT formation,thereby alleviating the economic burden on patients,enhancing quality of life,and increasing patient and family satisfaction.It is highly suitable for clinical application.
