Abstract
Systems, devices, and methods are provided for dispensing material from a container. Devices can include driving means for providing one or more forces, and actuator means for activating the driving means whereby the driving means causes material to be dispensed from the container.
Claims22
A method for dispensing a material from a container, the method comprising:
- providing a driving arrangement that is adaptable between a first configuration and a second configuration;
- executing a first actuation of an actuator assembly to cause the driving arrangement to assume the first configuration such that the driving arrangement forces material from the container under a first force;
- and
- executing a second actuation of the actuator assembly to cause the driving arrangement to assume the second configuration such that the driving arrangement forces material from the container under a second force.
1 more element
A device that dispenses material from a container, the device comprising:
- a driving arrangement that is adaptable between a first configuration and a second figuration;
- and
- an actuator assembly coupled with the driving arrangement;
- wherein a first actuation of the actuator assembly causes the driving arrangement to assume the first configuration such that the driving arrangement forces material from the container under a first force, and a second actuation of the actuator assembly causes the driving arrangement to assume the second configuration such that the driving arrangement forces material from the container under a second force.
1 more element
A device that dispenses fluid from a syringe, the device comprising:
- a body that removably receives a syringe;
- a driving arrangement coupled with the body, where the driving arrangement is adaptable between a constrained configuration, a first active configuration, and a second active configuration, the driving arrangement comprising:
- a carriage comprising a spring support and a ram;
- a first spring coupled with the spring support, the first spring providing a first spring force;
- and
- a second spring coupled with the spring support, the second spring providing a second spring force;
- a first actuator coupled with the driving arrangement;
- and
- a second actuator coupled with the driving arrangement;
- wherein actuation of the first actuator releases the driving arrangement from the constrained configuration to assume the first active configuration such that the first spring and the second spring transmit the first spring force and the second spring force, respectively, from the carriage ram to the syringe plunger to dispense material from a syringe chamber;
- and
- wherein actuation of the second actuator causes the driving arrangement to assume the second active configuration such that only the first spring transmits the first spring force from the carriage ram to the syringe plunger to dispense material from the syringe chamber.
