Systems and methods for sustained medical infusion and devices related thereto
First Claim
1. A medical device for delivering therapeutic fluid to a body of a patient, the device comprising:
- a reusable unit comprising;
a controller, anda first portion of a fluid transfer system;
a disposable unit comprising;
a reservoir for holding the therapeutic fluid,a second portion of the fluid transfer system,an exit port, anda cradle for releasably receiving the reusable unit; and
a cannula unit comprising;
a cannula for insertion into the body of the patient, anda penetrating needle fitted to the cannula and configured to be removed from the cannula after insertion of the cannula into the body;
wherein;
upon coupling the reusable unit and the disposable unit, the first portion of the fluid transfer system operatively couples to the second portion of the fluid transfer system, enabling transfer of the therapeutic fluid from the reservoir to the exit port, andupon coupling the cannula unit and the disposable unit, and insertion of the cannula into the body of the patient, fluid communication is established from the exit port to the body, via the cannula, without the use of tubing external to the coupled reusable and disposable units.

Abstract
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.

19. A medical device for delivering therapeutic fluid to a body of a patient, the device comprising:
-
a reusable unit comprising; a controller, and a first portion of a fluid transfer system; a disposable unit comprising; a reservoir for holding the therapeutic fluid, a second portion of the fluid transfer system, a well configured for use with a cannula for inserting into the body through the well and coupling thereto to provide fluid communication between the disposable unit and the body; and a cannula unit configured for insertion into the disposable unit at the well, the cannula unit comprising; a cannula for insertion into the body of the patient through the well, and a penetrating needle fitted to the cannula and configured to be removed from the cannula after insertion of the cannula into the body; wherein; upon coupling the reusable unit and the disposable unit, the first portion of the fluid transfer system operatively couples to the second portion of the fluid transfer system, enabling delivery of the therapeutic fluid from the reservoir, and upon insertion of the cannula unit into the disposable unit at the well and insertion of the cannula into the body of the patient through the well, fluid communication is established from the disposable unit to the body, via the cannula, without the use of tubing external to the coupled reusable and disposable units.
