Abstract
An infusion system is disclosed for delivering fluid wherein the system has a flow control element within a spike member (100). The spike member (100) is a fluid extraction spike member having a fluid passageway (110) and a micro-electromechanical system (MEMS) element (108) operatively connected to the fluid extraction spike member (100).
Claims46
A medical infusion system comprising:
- a spike member having a fluid passageway;
- and,
- a micro-electromechanical system (MEMS) element operatively connected to the spike member.
A disposable medical line-set comprising:
- a length of tubing having a first end;
- a fluid extraction spike connected to the first end of the tubing;
- and
- a MEMS pump housed within the fluid extraction spike and operatively connected to the tubing.
A spike member for a medical infusion system comprising:
- a housing having a passageway therethrough;
- a piercing member connected to one end of the housing and in fluid communication with the passageway;
- and
- a MEMS pump in communication with the passageway and contained within the housing.
An infusion system comprising:
- a container adapted to contain a flowable substance;
- a spike member comprising a passageway therethrough and in fluid communication with the container, the spike having a MEMS pump operatively connected to the spike;
- and
- a system of tubing having one end connected to the spike and in fluid communication with the passageway and another end adapted to be connected to a patient.
A medical fluid extraction member comprising:
- a substantially rigid body portion having first and second ends;
- a first fluid passage having an opening defined at each end of the body and passing therethrough;
- a second fluid passage having a first opening defined at the first end of the body and passing a distance through the body and a second opening defined on another portion of the substantially rigid body;
- and
- a MEMS fluid pump operatively communicating with one of either the first fluid passage and the second fluid passage.
