A blood purification apparatus that is capable of performing a liquid spill prevention operation and uniformizing the amount of air introduced through an opened portion. The blood purification apparatus includes a dialysate introduction line that allows dialysate to be introduced into a dialyzer; a dialysate discharge line that allows the dialysate to be discharged from the dialyzer; coupling tools that allow free switching between a connected state which causes a closed circuit, and an opened state which causes the closed circuit to be opened to form an opened portion; and a control means that performs a liquid spill prevention operation in which external air is introduced through the opened portion. An air detection means, by which air introduced through the opened portion is detectable, is provided in the vicinity of the coupling tools, and the control means stops the liquid spill prevention operation when air is detected by the air detection means.

The present invention relates to a medical device, in particular a blood treatment device and in particular a dialysis machine, having at least one handle arrangement, in particular a handle arrangement for a door, wherein the handle arrangement has at least one handle that is configured in ring shape; and wherein the handle arrangement furthermore has at least one disinfection unit that works with light, preferably with UV light, and that is arranged to disinfect the handle, with the handle arrangement furthermore having at least one drive unit that is configured to move the handle along the disinfection unit.

An extracorporeal blood purification system with at least one extracorporeal blood purification apparatus, preferably dialysis machine, which is prepared to go through a centrally controlled disinfection process for a blood purification process, as well as with an internal fluid line system which is disinfected at least during the disinfection process by a disinfectant, including an internal or external disinfecting or cleaning case which is at least during the disinfection process via at least one case connection connected to the internal fluid conduit system to receive disinfectant.

An electromagnetic radiation (EMR) delivery system for delivering EMR at wavelengths, intensities, exposures, and durations to locations inside and/or outside a patient's body in, on, and surrounding a tubular structure such as a tube, catheter, and/or a catheter extension to prevent, reduce, and/or eliminate infectious agents in, on, or surrounding the tubular structure. A smart light engine box generates the therapeutic EMR, controls treatments, and monitors the health of the system. A fiber optic disposable makes at-home use of the EMR delivery system possible. Specific embodiments of the EMR delivery system for use with peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.

A hemodialysis system is disclosed. The hemodialysis system includes a dialyzer, a saline container including saline, and a disposable set comprising a blood pumping tube fluidly connected to a first end of the dialyzer, an arterial line fluidly connected to a first end of the blood pumping tube, a venous line fluidly connected to a second end of the dialyzer, a saline line fluidly connected to the blood pumping tube and the saline container, and a dialyzer line fluidly connected to a second end of the blood pumping tube and a second end of the dialyzer. The hemodialysis system also includes a dialysis instrument comprising an arterial line clamp, a venous line clamp, and a saline valve. The saline rinses blood out of the arterial line when the venous line clamp is closed, the arterial line clamp is opened, and the saline value is opened.

A blood purification device includes: a control device that controls supply of a dialysis solution to a blood purifier; a dialysis solution supply tube in which a dialysis solution flows from the control device toward the blood purifier; a dialysis solution discharge tube in which the dialysis solution flows from the blood purifier toward the control device; a supply side coupler that connects between the dialysis solution supply tube and a dialysis solution inflow pipe of the blood purifier; and a discharge side coupler that connects between the dialysis solution discharge tube and a dialysis solution outflow pipe of the blood purifier. At least one of the supply side coupler and the discharge side coupler includes a light source unit configured to irradiate the interior of the coupler with ultraviolet light.

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.
