A portable device designed to hold a portable medical device (e.g., long-term recorder, portable oxygen equipment, urine collection bag, tracheostoma protector, infusion pump) during ambulation or sleep; it is neither designed to hold an invasive tube/catheter to the skin surface (i.e., not a catheter/tube holder), nor to house and protect a device from damage (i.e., not a rigid case/housing). It is typically designed as a wearable bag, pouch, strap, belt, or clothing, or as a trolley with wheels. This is a reusable device.
