A device for control of fluid flow with closed loop quasi static adjustment of in-line pressure-based resistance. The disclosed device and methods of using the device provide for the ability to control a flow rate with a highly portable device; the ability for an operator to safely use the device with minimal training; the ability to automatically switch between a primary and secondary fluid; the ability to maintain a flow rate through a tubing set even when the control device is removed; and the ability to measure fluids introduced with a manual bolus injection.

A tool system for operating an irrigation pump. The pump includes a fixed pump head driven by a pump motor and a removable tube set. A readable memory such as a RFID is integral with the tube set. The tube set memory contains data describing the physical characteristics of the tube set. A control console reads the data in the tube set memory. Based on these data, the control console then regulates the operation of the pump motor so that fluid, when required, is delivered at those flow rates. These data are also used by the control console to regulate priming of the pump so that when the system is initially set up a head of irrigation fluid can be pumped close to the end of the handpiece from which the fluid is to be discharged.

A medical pump for use with a tube set having a slack portion includes a pump housing and a pumping mechanism to meter fluid into the outlet line from the inlet line. A tube snap or a tube snap set is located on the pump housing remote from the pumping mechanism to gather and hold a slack portion between first and second tube snaps. In addition or alternatively, a tube hanger can be attached to the pump housing to allow insertion of a slack portion between the tube hanger and the pump housing.

A method for making a peritoneal dialysis therapy machine having a tubing set includes: packaging an end of each of a plurality of the tubes of the set in a body; arranging the tubes according to a sequence of steps of a dialysis treatment set-up so that a user is urged to remove the tubes from the single body in a desired order; and configuring the body to plug connectors attached to each of the ends of the tubes.

An injection system includes a fluid delivery system, a drive mechanism, a controller and a tubing set. The fluid delivery system includes a fluid container and a pumping mechanism having an inlet in fluid connection with the fluid container and an outlet. The tubing set is adapted to be placed in removable fluid connection with the outlet of the pumping mechanism and a patient. The drive mechanism is in operative connection with the pumping mechanism to pump fluid from the fluid container. First and second information stores, such as bar codes or RFID tags, are associated with the pumping mechanism and the tubing set, respectively. The controller is in operative connection with the drive mechanism and adapted to read the first information store and the second information store to at least partly control the operation of the drive mechanism based thereon.

The subject invention is directed to a new and useful coupling system for connecting a tube set to a trocar. More particularly, the system includes a trocar connector having no more than two coaxial flow passages formed therein including an inner flow passage and an outer flow passage. The inner flow passage is defined by an inner annular wall and the outer flow passage is defined between the inner annular wall and an outer annular wall. A dual lumen tube set is included with a first tube having a first diameter and a second tube having a second diameter that is greater than the diameter of the first tube. The system further includes a coupling including a generally cylindrical body having a first end portion configured to mate with the two coaxial flow passages of the trocar connector and a second end portion configured for attachment to the two tubes of the dual lumen tube set.

A connector includes a male connector section having a cavity, a female connector section having a cavity to which another male connector section the same as the male connector section can be connected, a male lock section or a female lock section, disposed adjacent to the male connector section so that the connection direction thereof is parallel to that of the male connector section, a female lock section disposed adjacent to the female connector section so that the connection direction thereof is parallel to that of the female connector section, and to which another male lock section the same as the male lock section can be coupled, or a male lock section disposed adjacent to the female connector section so that the connection direction thereof is parallel to that of the female connector section, and to which another female lock section the same as the female lock section can be coupled, and a seal member formed from an elastic material, for maintaining liquid-tightness of the connection between the other male connector section and the female connector section in a locked condition where the other male lock section and the female lock section are coupled to each other, wherein an unlocking sound, which enables recognition of unlocking, is generated at a time of unlocking when the locked condition is released.

A folding bicycle comprises a retractable front tube set. Handles at two sides of the top of the front tube set can be folded to the same side. An eccentric rotation device is pivotally provided at the top of the front tube set to drive an internal tube to retract in an outer tube for positioning. A seat tube is pivotally connected with the front tube set. A saddle is provided at the top of the seat tube. A rear tube is pivotally connected with the seat tube. A fastening device is provided between the rear tube and the seat tube to fix the seat tube. The front tube set, the seat tube and the rear tube are connected together by a joint link, which provides the function of a joint to let the front tube set, the seat tube and the rear tube unfold or fold with one another.

A kit of parts comprises a system and instructions for use for controlling patient temperature which uses a central venous line catheter having a heat exchange element. The central venous line catheter is provided with one or more lumens for providing access to the central blood supply of the patient, and with additional lumens for communicating heat exchange fluid to the heat exchange element. Heat exchange fluid temperature is controlled through a feed back loop in which patient temperature is sensed and used to control a temperature control unit comprising a heating device and / or a cooling device in heat exchange relationship with the heat exchange fluid. A tubing set transports the heat exchange fluid between the central venous line and the temperature control unit, with a pump serving to circulate the fluid in a closed fluid circuit in the system.
