Abstract: A drug delivery device includes a microcontroller, a pressure sensor, and/or a fluid pathway including a reservoir, a pump downstream of the reservoir, and/or a fluid line downstream of the pump. The reservoir may be configured to receive a fluid. The pump may be configured to deliver the fluid from the reservoir to the fluid line. The pressure sensor may configured to measure a pressure in the fluid pathway. The microcontroller may be programmed and/or configured to: receive, from the pressure sensor, the pressure measured in the fluid pathway; determine, based on the pressure measured in the fluid pathway, whether the reservoir is empty of the fluid; and/or control an output device to provide an indication associated with the determination of whether the reservoir is empty of the fluid.

Abstract: A drug delivery device may include a pressure sensor, a microprocessor, a fluid pathway including a reservoir, a pump downstream of the reservoir, and/or a fluid line downstream of the pump. The reservoir may be configured to receive a fluid, and the pump may be configured to deliver the fluid from the reservoir to the fluid line. The pressure sensor may be configured to measure a pressure in the fluid pathway downstream of the pump. The microcontroller may be programmed and/or configured to: receive, from the pressure sensor, the pressure measured in the fluid pathway downstream of the pump as the fluid is delivered to the fluid line; determine, based on the pressure measured in the fluid pathway, whether the fluid delivered to the fluid line includes a gas bubble; and control an output device to provide an indication associated with the determination a gas bubble.

Abstract: A disinfection tip is described for disinfecting a threaded connector of a syringe. The disinfection tip includes a cylindrical outer housing, a substantially cylindrical inner housing extending from a distal wall of the outer housing, a distal chamber defined by the outer sidewall of the inner housing, the inner wall of the outer housing and the distal wall of the outer housing, the distal chamber being in fluid communication with the cavity, the distal chamber retaining a disinfectant or antimicrobial agent when the disinfection tip is disposed within an outer wall of the luer connector of the syringe and, at least one jet orifice radially disposed on the inner rim in fluid communication with the distal chamber allowing for fluid to pass from the distal chamber through the jet orifice directing the disinfectant or antimicrobial agent towards a center of the outer housing when the disinfection tip is further inserted into the luer connector of the syringe, the insertion of the disinfection tip causing the volume of the distal chamber to reduce and expel disinfectant or antimicrobial agent through the at least one jet orifice.
