The present invention relates to a dialysis machine having two hydraulic connectors at the dialyzate side to which a respective connection line having a filter coupling is connected for connection to a dialyzer, with the hydraulic connectors being an inflow connector for feeding fresh dialysis liquid to the dialyzer and a backflow connector for draining consumed dialyzate from the dialyzer, and having two parking positions associated with the respective hydraulic connectors for storing the filter couplings when not in operation, wherein the filter couplings of both hydraulic connectors are equipped with a connection sensor which recognizes a connecting of the filter coupling to a dialyzer and/or that both parking positions are provided with separate covers.

The invention relates to a device for discharging wastewater, in particular used or spent dialysate, comprising a plurality of line connections 3, 4, 5 for connecting wastewater lines, in particular wastewater lines of dialysis machines. The device according to the invention is designed as a part which can stand on the bottom of a basin. Sufficient stability can be achieved on account of the weight (gravitational force) of the device alone, without it being necessary to secure the device. Recontamination is prevented effectively in that the line connections 3, 4, 5 are in fluid connection with at least one inflow line, the lower end of which is arranged so as to be spaced apart from the bottom, such that a free-fall distance is formed. In a preferred embodiment, a casing 1 surrounds the at least one inflow line 6, 7, 8.

The casing 1 forms a splash guard in the form of a hood such that the wastewater, which emerges from the inflow lines 6, 7, 8 under relatively high pressure, cannot reach the surroundings.

A port arrangement (1) comprising a fluid module (2) incorporating a first port (3) arranged to receive a first connector (4) and a second port (5) arranged to receive a second connector (6). The first port (3) provides a first circumferential space (3c) around a first tube (3a). The second port (5) provides a second circumferential space (5c) around a second tube (5c). The fluid module (2) further incorporates a bypass channel (7) connecting the first circumferential space (3c) and the circumferential second space (5c). The port arrangement (1) further comprises a door (20) comprising a first seal (21) and a second seal (22) arranged to seal the first circumferential space (3c) and the second circumferential space (5c) against the outside. The disclosure also relates to a purified water producing apparatus (100) comprising the port arrangement (1), and a method for performing port cleaning of the water producing apparatus (100).

A nested syringe comprising: a first chamber comprising: an inner tube extending from a base of the first chamber and defining a base opening in the base; an adapter tube in fluid communication with the inner tube via the base opening; at least one base port in the base for providing fluid communication between the adaptor tube and a first inner volume of the first chamber; a second chamber, adapted for insertion into the first chamber wherein the second chamber comprises a third port adapted to provide fluid communication between the inner tube and a second inner volume of the second chamber and adapted for preventing fluid communication between the first inner volume and the second inner volume when the second chamber is inserted into the first chamber and the inner tube penetrates the third port; and a plunger, wherein the plunger is adapted for insertion into the second chamber.

This dialysis-fluid supply system, which mixes a diluent and at least two drugs to generate a dialysis fluid, and outputs said dialysis fluid, is provided with: two tanks which mix the drugs and the diluent to generate the dialysis fluid, and store said dialysis fluid; a water supply device and a drug supply device which supply the diluent and the drugs to each of the tanks; mechanisms for outputting, to a dialysis device, the dialysis fluid stored in each of the tanks; and a control unit for controlling the driving of these. During output of the dialysis fluid from at least one of the tanks, the control unit sequentially switches the supply destination tank for the drugs and the diluent, and the dialysis-fluid output source tank, between the two tanks in order to generate the dialysis fluid in the other tank.

A hemodialysis system is disclosed. The hemodialysis system includes a disposable set including a blood pumping tube, a fresh dialysate pumping tube, and a spent dialysate pumping tube. The hemodialysis system also includes a dialysis instrument including a blood pump head, a fresh dialysate pump head, a spent dialysate pump head, a first motor positioned and arranged to operate the blood pump head, a second motor positioned and arranged to operate the fresh dialysate pump head, and a third motor positioned and arranged to operate the spent dialysate pump head. When the disposable set is loaded into the dialysis instrument, the blood pumping tube comes into registry with the blood pump head, the fresh dialysate pumping tube comes into registry with the fresh dialysate pump head, and spent dialysate pumping tube comes into registry with the spent dialysate pump head.

A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

The present invention concerns an electronic safety system for a RO-device (RO) which is designed to be used with at least one dialysis device (D). The system comprises the RO-device (RO), which is designed for the production of ultrapure water and which is developed with a sensor unit (S) for collecting sensor data and whereby the RO-device (RO) comprises an electronic data interface (RO-S) in order to send the sensor data collected by the sensor unit (5); and it also comprises an analysis unit (AE) which is designed to analyse a water sample with regards to safety requirements and especially with regard to contamination and to generate result data whereby the analysis unit (AE) is also developed with a analysis interface (AE-S) in order to send the generated result data in electronic form; and a network (NW) for the data exchange between the medical-technical entities, especially between the RO-device (RO) and the analysis unit (AE).

The present application relates to a method for disinfection of a temperature control device for human body temperature control during extracorporeal circulation which temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the temperature control device. According to the present application, the temperature control device is connected to a temperature control liquid supply and, during operation of the temperature control device for human body temperature control, a disinfectant is selectively added to the temperature control liquid supply upstream of the temperature control device.

An optical connector includes a first sub-assembly that is factory-installed to a first end of an optical fiber and a second sub-assembly that is field-installed to the first end of the optical fiber. The optical fiber and first sub-assembly can be routed through a structure (e.g., a building) prior to installation of the second sub-assembly. The second sub-assembly interlocks with the first sub-assembly to inhibit relative axial movement therebetween. Example first sub-assemblies include a ferrule, a hub, and a strain-relief sleeve that mount to an optical fiber. Example second sub-assemblies include a mounting block; and an outer connector housing forming a plug portion.
