Abstract: A drug delivery device is provided. The drug delivery device includes a drug reservoir in fluid communication with a microneedle array. The drug delivery device has a sliding actuation mechanism that may be activated by a button or lever. Actuation of the drug delivery device inserts the microneedle array into the skin of a subject and causes a piston to compress the drug reservoir, thereby delivering the drug through the microneedle array to the subject.

Abstract: A bladder arrangement is provided for a microneedle-based drug delivery device. The bladder arrangement includes a flexible membrane having an inner surface, an outer surface and an outer periphery. A bladder member, having a rigidity greater than the flexible membrane, includes an inner surface, an outer surface and an outer periphery. The inner surface of the flexible membrane and the inner surface of the bladder member define a chamber for receiving a drug therein. At least one microneedle is operatively connected to the bladder member. The at least one microneedle has an input and an output receivable within the individual. A valve operatively connects the input of the at least one microneedle and the chamber.

Abstract: A medical pump includes a chassis having a fixed seat, and a main carriage having a carriage footing for receiving a fluid delivery device and restricting its movement. An actuator automatically moves the main carriage between open and closed positions to engage the fluid delivery device to the seat. The seat establishes the position of both the main carriage and fluid delivery device in the closed position. The actuator is connected to the main carriage by a rear carriage assembly having a manual release element for disengaging the actuator from rear carriage assembly and thereby from the main carriage. A processing unit detects jam conditions by processing carriage position data and electrical load data from the actuator.

Abstract: A drug delivery device for delivering a drug to a subject is provided. The drug delivery device includes a housing, a drug reservoir supported by the housing containing the drug and a hollow microneedle supported by the housing. The hollow microneedle is moveable from an inactive position to an activated position, wherein, when the hollow microneedle is moved to the activated position, the tip portion of the hollow microneedle is configured to penetrate the skin of the subject. The drug delivery device includes a channel having an input in communication with the drug reservoir and an output in communication with the hollow microneedle. The channel provides fluid communication between the drug reservoir and the hollow microneedle, such that the drug is permitted to flow from the drug reservoir through the channel and through the hollow microneedle.

Abstract: A device for delivering a drug into the skin of a subject is provided. The device includes a drug reservoir and a microneedle having a tip, a length, and a tip sharpness. The microneedle is coupled to the reservoir. The device includes a microneedle actuator coupled to the microneedle configured to drive the microneedle into the skin of the subject upon activation. The tip sharpness and the actuator allow the microneedle to pass through an outer layer of the skin upon activation, and the length is limited such that the tip does not extend past a desired depth below the surface of the skin of the subject, wherein the desired depth is located in the papillary dermis or the reticular dermis.

At least one microneedle is operatively connected to the bladder member. The at least one microneedle has an input and an output receivable within the individual. A valve operatively connects the input of the at least one microneedle and the chamber.

Abstract: A pet waste collection device has a pair of opposing jaws movable between a closed jaw state and an open jaw state, and a liner bag may be situated about the jaws so that closure of the jaws about pet waste encases the waste within a bag. The jaws do not simply pivot into a closed state, and rather they travel toward each other in a path substantially parallel to the surface upon which the waste rests to close about the waste, and they then retract. Opposing shells which open and close about the jaws may strip the bag from the jaws when the jaws are closed about the waste.

Abstract: An automatic control device for a hot water heating system, comprises a first relay being connectable to a water temperature switch such that the first relay is energized when the switch is closed and a second relay connected to the first relay such that the second relay is energized when the first relay is energized. The first relay is connectable to an electrically operated valve controlling the flow of high temperature water from a boiler to a heat exchanger operably associated with a water heater such that the electrically operated valve is opened when the first relay is energized and closed when the first relay is de-energized. The first relay is connectable to the boiler such that the boiler is turned on when the first relay is energized.
