Title (EN) WEARABLE NON-INVASIVE APPARATUS FOR AND METHOD OF ENHANCING LOWER LIMBS VENOUS RETURN OF A SUBJECT
(FR) APPAREIL NON-INVASIF POUVANT ÊTRE PORTÉ ET PROCÉDÉ POUR AMÉLIORER LE RETOUR VEINEUX DE MEMBRES INFÉRIEURS D'UN SUJET
Abstract:
(EN) In various embodiments, a wearable non-invasive apparatus for enhancing lower limb venous return of a subject may be provided. The apparatus may include a monitoring device configured to determine a venous state of a subject such as a photoplethysmography (PPG) sensor. The apparatus may also include a neuromuscular electrical stimulation (NMES) device configured to generate an electrical stimulus in response to the determined venous state and concurrently stimulate the triceps surae and the deep posterior calf muscle of the subject with the generated electrical stimulus to enhance lower limb venous return. In an alternative embodiment, electrical stimulation can be at the tibial nerve of the subject to retrograde target the triceps surae and the deep posterior calf muscle of the subject.
(FR) Dans divers modes de réalisation, l'invention concerne un appareil non-invasif pouvant être porté pour améliorer le retour veineux de membre inférieur d'un sujet. L'appareil peut comprendre un dispositif de surveillance configuré pour déterminer un état veineuse d'un sujet, tel qu'un capteur de photopléthysmographie (PPG). L'appareil peut également comprendre un dispositif de stimulation électrique neuromusculaire (NMES) configuré pour générer un stimulus électrique en réponse à l'état veineux déterminé et, simultanément, stimuler le triceps sural et le muscle de mollet postérieur profond du sujet avec le stimulus électrique généré pour améliorer le retour veineux de membre inférieur. Dans un autre mode de réalisation, une stimulation électrique peut être au niveau du nerf tibial du sujet pour cibler de manière rétrograde le triceps sural et le muscle de mollet postérieur profond du sujet.
