Abstract
Provided herein is a system for sequential delivery of therapeutic compositions, including a first fluid source and a second fluid source, one or more first sensors associated with each of the first fluid source and the second fluid source, an actuator-actuated valve, and a processor in communication with the one or more sensors, wherein the processor is programmed or configured to control, based on data received from the one or more sensors, the actuator-actuated valve to stop and/or cause delivery of therapeutic compositions from the fluid sources.
Claims31
A system for sequential delivery of therapeutic compositions according to medication prescription parameters, comprising:
- a first fluid source containing a first therapeutic composition and a second fluid source containing second therapeutic composition different than the first therapeutic composition;
- one or more first sensors associated with each of the first fluid source and the second fluid source;
- one or more second sensors associated with the first fluid source and/or the second fluid source, the one or more second sensors configured to detect an amount of fluid in the first fluid source and/or the second fluid source;
- an actuator-actuated valve comprising:
- a valve manifold comprising a first inlet port, a second inlet port, and an outlet port, wherein the first inlet port is in fluid communication with the first fluid source and the second inlet port is in fluid communication with the second fluid source;
- a valve spool extending within the valve manifold, the valve manifold and valve spool defining a first valve passageway and a second valve passageway, wherein the valve spool is moveable relative to the valve manifold between a first position in which the first inlet port and the outlet port are in fluid communication via the first valve passageway and a second position in which the second inlet port and the outlet port are in fluid communication via the second valve passageway;
- and
- an actuator configured to displace the valve spool relative to the valve manifold between the first position and the second position;
- and
- a processor in communication with the one or more first sensors and the one or more second sensors, the processor configured to control, based on flow data received from the one or more first sensors that a predetermined amount of the first therapeutic composition has been delivered to the patient, and in response to determining that the predetermined amount of the first therapeutic composition has been delivered to the patient, causing the actuator to displace the valve spool relative to the valve manifold between the first position and the second position to maintain an accurate flow rate and an accurate flow sequence of the first therapeutic composition and the second therapeutic composition according to the medication prescription parameters.
7 more elements
A computer-implemented method for delivering a plurality of therapeutic compositions to a patient through a system according to medication prescription parameters, the method comprising:
- providing:
- a first fluid source;
- a second fluid source;
- one or more first sensors associated with each of the first fluid source and the second fluid source;
- one or more second sensors associated with the first fluid source and/or the second fluid source, the one or more second sensors configured to detect an amount of fluid in the first fluid source and/or the second fluid source;
- and
- an actuator-actuated valve comprising:
- a valve manifold comprising a first inlet port, a second inlet port, and an outlet port, wherein the first inlet port is in fluid communication with the first fluid source and the second inlet port is in fluid communication with the second fluid source;
- a valve spool extending within the valve manifold, the valve manifold and valve spool defining a first valve passageway and a second valve passageway, wherein the valve spool is moveable relative to the valve manifold between a first position in which the first inlet port and the outlet port are in fluid communication via the first valve passageway and a second position in which the second inlet port and the outlet port are in fluid communication via the second valve passageway;
- and
- an actuator configured to displace the valve spool relative to the valve manifold between the first position and the second position;
- delivering, through the first inlet port and from the first fluid source, a first therapeutic composition to a patient;
- determining, with at least one processor, that a predetermined amount of the first therapeutic composition has been delivered to the patient;
- in response to determining that the predetermined amount of the first therapeutic composition has been delivered to the patient, causing, with the actuator controlled by at least one processor, the valve spool to move from the first position to the second position;
- and
- delivering, through the second inlet port and from the second fluid source, a second therapeutic composition to the patient to maintain an accurate flow rate and an accurate flow sequence of the first therapeutic composition and the second therapeutic composition according to the medication prescription parameters, the second therapeutic composition different than the first therapeutic composition.
13 more elements
A computer-implemented method of delivering therapeutic compositions to a patient according to medication prescription parameters, the method comprising:
- monitoring, with at least one processor and based at least in part on flow data received from a first sensor, delivery of a first therapeutic composition to a patient;
- determining, with the at least one processor and based at least in part on flow data received from the first sensor, that a predetermined amount of the first therapeutic composition has been delivered to the patient;
- and
- in response to determining that the predetermined amount of the first therapeutic composition has been delivered to the patient, causing, with the at least one processor, a valve to stop flow of the first therapeutic composition to the patient and begin flow of a second therapeutic composition to the patient and to maintain an accurate flow rate and an accurate flow sequence of the first therapeutic composition and the second therapeutic composition according to the medication prescription parameters, the second therapeutic composition different than the first therapeutic composition.
