Abstract: A first venous rhythm of a patient is detected above a venous insertion site when a venous catheter connected to an infusion set is inserted into the venous insertion site and, concurrently with the first venous rhythm, a second venous rhythm is detected at a location remote from the venous insertion site. An irregularity between the first and second venous rhythms is identified, and a failure of the venous catheter is determined based on the identified irregularity satisfying a irregularity threshold. An alarm may be provided on detecting the irregularity or the failure of the venous catheter.

Abstract: A fluid flow disconnect sensor and alarm system includes first and second sensor units configured to be removably coupled to a first and second portions of a fluid connector assembly, respectively. The first sensor unit comprises a sensor configured to sense when the second sensor unit is within a threshold distance of the first sensor unit, and comprises a transmitter configured to transmit, to a device remote from the first and second sensor units, an indication regarding whether the first and second portions of the fluid connector assembly are coupled together responsive to the sensing. A computing device receiving the indication determines when the first and second portions of the fluid connector assembly are coupled together, and when the assembly becomes disconnected, and may generate an alarm when the first and second portions become disconnected.

Abstract: An IV bag wringer includes a frame defining a frame opening and multiple roller assemblies disposed within the frame opening. Each roller assembly includes a shaft coupled to the frame and a roller coupled to the shaft. Two opposing rollers are positioned to receive an IV fluid bag in a gap between the rollers such that the IV bag wringer hangs on the IV fluid bag. The weight of the IV bag wringer moves it downward along the IV fluid bag so that the opposing rollers squeeze fluid out of the IV fluid bag at a rate greater than a gravity flow rate from the IV fluid bag alone. Hand cranked IV bag wringers, motor actuated IV bag wringers and methods of operating IV bag wringers are also provided.

Abstract: A mini peristaltic pump is provided that includes a base plate, first and second gears disposed on a first side of the base plate, first and second roller wheels disposed on a second side of the base plate and coupled to the first and second gears, respectively, and one or more rollers coupled to each of the first and second roller wheels. A motor is coupled to the first gear, the motor configured to rotate the first gear and the first roller wheel to move the one or more rollers coupled to the first roller wheel in a first orbital path to peristaltically engage and compress a hand pump disposed between the first and second roller wheels. A profile feature on the base may be provided instead of the second gear and roller wheel. Systems and methods are also provided.
