Systems and methods for sustained medical infusion and devices related thereto

摘要

Embodiments of the invention are directed to systems, methods and devices for sustained medical infusion with controlled rate injection of a fluid into a body. Such a system may include a first separate reusable unit, a second separate depletable unit a third separate disposable unit having a cannula, and may include a fourth separate remote control unit. Emission of appropriate instructions from the fourth unit, when the first unit, the second unit, and the third unit are coupled together in associative operation and disposed on the skin, power is supplied to an engine for generating motion to a fluid transfer system, and when the cannula is inserted in the body, fluid is transferred from the reservoir to the body, via the tube and the cannula.

主权项

1. A medical device for delivering therapeutic fluid to a body of a patient, the device comprising:
a first unit comprising a first portion of a fluid transfer system; a second unit coupleable to the first unit, the second unit comprising a reservoir for holding the therapeutic fluid, and a second portion of the fluid transfer system coupleable to the first portion of the fluid transfer system when the first unit is coupled to the second unit; a cradle configured for releasably receiving the first unit, the cradle comprising a releasable mechanism for coupling both the first and second units when engaged; and a cannula unit coupleable to the second unit, the cannula unit comprising a cannula for insertion into the body of the patient; wherein upon coupling the first, second, and cannula units, and insertion of the cannula into the body of the patient, fluid communication is established from the reservoir to the body, via the cannula, without the use of tubing external to the coupled first and second units.
