DRUG CONTAINER HARNESS TO PERMIT AMBULATORY INFUSION AND FACILITATE CONSTANT DRUG DELIVERY RATE

摘要

A harness (10) of preferred construction for wear by a human being provides a structure for minimizing the temperature rang of an ambulatory liquid drug supply in a container (56). The harness includes fastening structures which retain the container (56) of the drug supply which is to be infused into the venous system, in a manner which allows the patient to be ambulatory. The harness is particularly designed for those infusion devices in which the liquid drug viscosity has a measurable effect on drug delivery rate, such as those employing a pressurized bladder (58). The harness keeps the drug supply in close proximity to the skin of the person to enable heat transfer from the person to the drug supply to a degree which limits the effects of atmospheric temperature change on the drug supply temperature. The condition of limited temperature change stabilizes drug viscosity and therefore facilitates constant drug delivery flow rate into the person. The harness may be worn without altering normal wearing apparel and may be worn virtually inconspicuously.
