Blood line connector for a medical infusion device
InactiveUS20100056975A1Easy to useOptimize locationDialysis systemsMedical devicesLine tubingDialysis fluid
A blood line connector for a blood circuit of a hemodialysis unit with an ability to make two different types of fluid tight connections, e.g., a screw-type connection with a luer connector at a patient access and a press-in type connection with a dialysate circuit. The blood line connector may include a tube connection end arranged to sealingly engage with a blood circuit tube, and a patient access connection end with a frustoconical member having an internally threaded portion arranged to engage with an externally threaded patient access, and a pair of locking arms extending rearwardly from the frustoconical member. The locking arms may each have a finger depression portion and a barbed portion, and may be arranged to engage with a mating connector on the dialysis unit at the barbed portions to lock the frustoconical member in sealing engagement with the mating connector when making a press-in type connection.

A method and a device for supply of a dialyser in a dialysis unit with dialysis fluid is disclosed. At least one dialysis fluid concentrate is mixed with water to produce the dialysis fluid. The dialysis fluid concentrate is prepared in a reservoir unit in a given amount. A control and arithmetic unit calculates the dialysis fluid rate (Qd) such that, after a given treatment time (T<SB>B< / SB>) has passed, a given residual amount of dialysis fluid concentrate or no residual amount remains in the reservoir unit. It is preferable to empty the reservoir unit by the end of treatment.

Single-needle dialysis sytem utilizing a peristaltic pump with pumping and occluding rollers
A peristaltic roller pump includes a rotor carrying a pumping roller on one end and an occluding roller on the other end. Occluding roller has a number of protrusions designed to occlude the tubing section that is located under that roller as it moves over it in order to prevent any back flow through that section of the tube. Occluding roller is designed to not cause any pumping of fluid through the section of the tubing under that roller. Such design is useful in a single-needle dialysis system in which during a first phase of pumping blood is moved in one direction from the patient towards the dialysis unit and during the second phase of operation blood is returned to the patient in the opposite direction.
