Manually operable portable infusion device

摘要

A portable therapeutic fluid delivery device and a method for delivering a therapeutic fluid into a body of a patient are provided. In one aspect the therapeutic fluid delivery device and the method can be implemented using at least one housing securable to the body of the patient, a reservoir coupled to the at least one housing, a therapeutic fluid dispensing mechanism, a memory component, a controller, at least one bolus delivery button configured to signal the controller to initiate the delivery of the therapeutic fluid into the body of the patient; and, an inadvertent initiation prevention mechanism adapted for preventing the patient from activating the at least one bolus delivery button.

1. A method for delivering a therapeutic fluid into a body of a patient comprising:
providing a portable therapeutic fluid delivery device for delivering a therapeutic fluid into
a body of a patient, the device comprising:a reservoir for containing the therapeutic fluid;a dispensing mechanism for dispensing the therapeutic fluid from the reservoir toward the body of the patient;a memory adapted for storing at least one value corresponding to a therapeutic fluid delivery dose;a controller adapted for initiating delivery of the therapeutic fluid by activating the dispensing mechanism, the controller further adapted for limiting the delivery of the therapeutic fluid based on the at least one value stored in the memory;at least one housing configured for securing to the body of the patient, the at least one housing accommodating the reservoir, the dispensing mechanism, the memory and the controller;at least one bolus delivery switch coupled to a printed circuit board accommodated within the at least one housing, the at least one bolus delivery switch being configured to signal the controller to initiate delivery of the therapeutic fluid into the body of the patient; andan inadvertent initiation prevention mechanism adapted for preventing the patient from inadvertently activating the at least one bolus delivery switch; receiving a signal corresponding to activation of the at least one bolus delivery switch by the patient, the activation verified by the inadvertent initiation prevention mechanism; receiving at least one value corresponding to a therapeutic fluid delivery dose stored in the memory; initiating the delivery of the therapeutic fluid delivery dose into the body of the patient by activating the dispensing mechanism; and limiting the delivery of the therapeutic fluid into the body of the patient based on the at least one value stored in the memory.
