摘要： A dialysis system is disclosed for treatment of a first fluid with dialysis fluid, the dialysis fluid being a mixture of water and dialysis concentrate. The system comprises a dialyzer, a source of water, a source of dialysis concentrate, first and second fluid conducting means communicating with the sources of water and dialysis concentrate, pump means associated with the first and second fluid conducting means, and third fluid conducting means for conducting fluid from the pump means to the dialyzer. The pump means serves to draw water and dialysis concentrate through the first and second fluid conducting means respectively, and to mix the water and dialysis concentrate so that a mixture of water and dialysis concentrate is conducted through the third fluid conducting means.

摘要： Control apparatus for controlling or adjusting the position of a control member is disclosed. The control apparatus includes first and second members, pivotally connected together to pivot about a point. A control member is mounted on the first member and is disposed at a first distance from the pivot point. Coarse control means operatively associated with the control member are provided for coarsely adjusting the position of the control member relative to the second member. Further, fine control means are provided for finely adjusting the position of the control member relative to the second member. The fine control means acts at an action point on one of the first and second members to pivot the first and second members relative to each other about the pivot point. The action point at which the fine control means acts is a second distance from the pivot point which is greater than the first distance such that a selected amount of movement of the action point results in a change in position of the control member relative to the second member, the amount of change in position being less than the selected amount of movement.

摘要： Fluid conducting apparatus is disclosed for a dialysis system having a dialyzer, a source of dialysis fluid for the dialyzer, a heating chamber for heating dialysis fluid before introduction into the dialyzer, and pump means for pumping heated dialysis fluid from the heating chamber to and through the dialyzer. The fluid conducting apparatus includes first and second fluid conducting means. The first fluid conducting means is adapted to be connected to the source of dialysis fluid and to the heating chamber for introducing dialysis fluid into the heating chamber, and the second fluid conducting means is adapted to be connected to the heating chamber, the dialyzer and the pump means for conducting the fluid from the heating chamber to and through the dialyzer. The apparatus also includes shut-off means adapted to terminate the flow of heated dialysis fluid from the heating chamber to the dialyzer when the rate of flow of fluid out of the chamber exceeds the rate of flow of fluid into the chamber. In this way, the heating chamber will not be emptied of dialysis fluid.

摘要： An apparatus and method for the diffusion of substances between two fluids. The apparatus comprises at least one semipermeable membrane having first and second opposing surfaces, first conducting means for conducting a first fluid along the first surface of the membrane, and second conducting means for conducting a second fluid along a second surface of the membrane.

Mixing means are provided for directly mixing the first fluid into the second fluid after conduction of the first fluid along the first surface of the membrane. In the preferred embodiment, this mixing means comprises apertures at the downstream end of the membrane for introducing the first fluid directly into the second fluid flowing on the opposite side of the membrane.

摘要： A device for the transfer of one or more substances between a gas and a liquid, the gas being introduced into the liquid in the form of bubbles from which the said substances are transferred to the liquid whereupon the excess gas is removed together with any substances transferred from the liquid to the gas. Characteristic for the device is a narrow annular gap (10), arranged vertically, for the liquid, a gas inlet (20), arranged in close connection to this gap (10), this gas inlet being adapted so that it introduces the gas uniformly distributed along the whole periphery of the gap (10), and means (34,36) for the removal of the excess gas.The device is intended in particular to be used as a so-called oxygenator when the said liquid is blood and the said gas is oxygen or an oxygen mixture. Carbon dioxide from the blood will then be removed together with the excess gas.
