Abstract

A device for delivering fluid to a person including a reservoir for containing a fluid to be delivered to the person, a fluid transport device for dispensing fluid from said reservoir to the person, said fluid transport device including a proximal end in fluid communication with said reservoir and a distal end having a penetrating member for piercing the skin of the person to facilitate the delivery of fluid to the person through the fluid transport device, a housing containing said reservoir and said fluid transport device, said housing including an exit port for receiving said distal end of said fluid transport device upon injection of said distal end into said person and means for securing a first wall of said housing to the skin of the person, a injection activation device including a driving mechanism contacting said fluid transport device for driving said penetrating member from a first position within said housing, through said exit port to a second position, external to said housing and into the skin of said person, and an electrically driven actuator for activating said driving mechanism.

Claims

1. A device for delivering fluid to a person comprising:

a reservoir for containing a fluid to be delivered to the person;

a fluid transport device for dispensing fluid from said reservoir to the person, said fluid transport device including a proximal end in fluid communication with said reservoir and a distal end having a penetrating member for piercing the skin of the person to facilitate the delivery of fluid to the person through the fluid transport device;

a housing containing said reservoir and said fluid transport device, said housing including an exit port for receiving said distal end of said fluid transport device upon injection of said distal end into said person and means for securing a first wall of said housing to the skin of the person;

an injection activation device including a driving mechanism contacting said fluid transport device for driving said penetrating member from a first position within said housing, through said exit port to a second position, external to said housing and into the skin of said person; and

an electrically driven actuator for activating said driving mechanism.

2. The device of claim 1 wherein said electrically driven actuator comprises one of a shape memory alloy, a shape memory polymer, a piezo electric actuator and a solenoid.

3. The device of claim 1 further comprising a local processor programmed to activate said electrically driven actuator based on injection instructions;

and

a wireless receiver connected to the local processor for receiving injection instructions from a separate, remote control device and delivering the injection instructions to the local processor.

4. The device of claim 1 wherein said housing is free of user input components for providing injection instructions to the local processor.

5. The device of claim 2 wherein said housing is free of user input components for providing injection instructions to the local processor.

6. The device of claim 2 further comprising a remote control device separate from the fluid delivery device and including:

a remote processor;

user interface components connected to the remote processor for transmitting the injection instructions to the remote processor; and

a transmitter connected to the remote processor for transmitting the injection instructions to the receiver of the fluid delivery device.
