A filter CF1 for filtering dialysis fluid comprises the following: a housing 52 inside of which a filter material 51 is accommodated and which is vertically long; an introduction port 53 that is disposed in the lower part of the housing and that introduces dialysis fluid from an upstream-side flow path 23a; a filtered fluid lead-out port 54 through which filtered dialysis fluid, which has passed through the filter material, is lead out from the upper part of the housing to a downstream-side flow path 23b; and an unfiltered fluid lead-out port 55 through which unfiltered fluid is lead out from the upper part of the housing to a waste fluid flow path 57. When removing the filter from a dialysis fluid circuit 4, fluid is suctioned from the inside of the housing via the upstream-side flow path by using fluid suction means 64A, and a gas is caused to flow into the housing from at least either one of the waste fluid flow path and the downstream-side flow path by using gas inflow means 65. The fluid may be suctioned from the downstream-side flow path and the gas may be caused to flow in from the upstream-side flow path, or the fluid may be suctioned from the waste fluid flow path and the gas may be caused to flow in from the downstream-side flow path. Residual fluid in the filter can be reduced.

A peritoneal dialysis system includes (i) a fill container, and (ii) an energizing unit that removably accepts the fill container, the energizing unit including a sterilization source so configured and arranged relative to the fill container when accepted by the energizing unit to place fluid within the fill container in a physiologically safe condition for delivery to the peritoneal cavity of a patient.

A blood purification apparatus including a line section through which working dialysate to be introduced into a blood purifier or drain liquid discharged from the blood purifier is caused to flow; a delivery unit that delivers liquid in the line section; an introduction port connected to a supply route through which undiluted dialysate or the working dialysate is supplied, the introduction port allowing the undiluted dialysate or the working dialysate in the supply route to be introduced into the apparatus; an introduction route connected to the introduction port and through which the undiluted dialysate or the working dialysate introduced from the introduction port flows into the line section; a valve unit provided to the introduction route and being capable of opening or closing the introduction route by being opened or closed; and a control unit that controls an operation of opening or closing the valve unit. The control unit is capable of executing a flushing step in which when a cleaning solution or a disinfecting solution is caused to flow through the supply route, the valve unit is opened to allow the cleaning solution or the disinfecting solution flowing in the supply route to flow into the introduction route and through the line section to be discharged to an outside of the apparatus.

Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cassette (e.g., a disposable cassette) positionable within a port formed in the dialysis machine. The dialysis system may also include a cleaning cartridge insertable into the port. The cleaning cartridge may be arranged and configured to collect, remove, etc. any foreign material or debris from the port.

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.

A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement with a warm water inlet and a cold water inlet in fluid flow communication with a temperature mixing component. The thermostatic mixing component mixes the cold water and the warm water to produce mixed water maintained at a predetermined temperature between the temperature of the cold water and the temperature of the warm water. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer, thermostatic mixing component, a trap primer, or any combination of the foregoing.

A hemodialysis machine includes a main body and a door connected to the main body. The door and the main body cooperate to define a non-removable chamber. The door is openable relative to the main body of the hemodialysis machine to allow a salt to be placed into the non-removable chamber when the door is in an open position. The main body further includes a fluid inlet, a fluid outlet, and a pumping mechanism. The fluid inlet and the fluid outlet are in fluid communication with the non-removable chamber. The pumping mechanism is configured to deliver a fluid from a fluid source to the non-removable chamber through the fluid inlet to mix with salt within the non-removable chamber to form a salt solution that exits the non-removable chamber through the fluid outlet.

A water filtration system uses previously used medical filters, such as dialysis filters, for water purification. After medical use the filters are cleaned and sterilized and mounted singly or in groups so as to receive input water under pressure. The system produces sterile filtered water.

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.

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.
