A dialysis fluid system includes a dialysis fluid inlet; a dialysis fluid outlet; a pump positioned and arranged to pump dialysis fluid through the dialysis fluid inlet and the dialysis fluid outlet; and an inductive heater located between the dialysis fluid inlet and the dialysis fluid outlet, the inductive heater including a fluid flowpath positioned and arranged to receive non-heated dialysis fluid from the dialysis fluid inlet and to output heated dialysis fluid to the a dialysis fluid outlet, a conductive heater element located within the fluid flowpath so as to be or act as a secondary coil of a transformer, and a primary coil of the transformer located outside of the fluid flowpath and positioned so as to magnetically induce a current into the conductive heater element, causing the conductive heater element and surrounding fluid to heat.

A device for ocular surgery includes a surgical handpiece including a power cord and an aspiration needle for removing ocular material from an eye, and co-extruded tubing. The tubing includes an aspiration tube for receiving the ocular material removed from the eye by the surgical handpiece, an irrigation tube integrally formed with the aspiration tube for supplying irrigation fluid to the surgical handpiece, and a ridge defined along at least a majority of a length of the co-extruded tubing, the ridge defining a groove for receiving the power cord of the surgical handpiece.

Disclosed in some embodiments is an electronic intravenous infusion pump provided with a disposable, insertable pump cartridge that is connectable to one or more intravenous fluid infusion sources, wherein a user interface on a touch display screen interacts with and responds to the user's insertion of the cassette, and/or wherein the pump is enabled to program a course of infusion for a patient based upon information obtained from the inserted cassette and/or the one or more fluid infusion sources connected to the cassette.

Provided is a contrast medium injection system that allows a connector of a tube connected to a patient to be reliably locked and easily unlocked with a small force and kept clean in normal use.

The system includes a detachably attachable injection line kit, at least one fluid injection flow path and a first connector provided on a downstream end of the flow path. The kit includes at least one patient connection flow path and a second connector that is provided on an upstream end of the patient connection flow path and detachably attachable to and engageable with the first connector. The contrast medium injection system body has a first set position where the kit is set and a second set position where the first and second connectors are engaged more deeply than in the first set position.

Provided is a blood component sampling cassette which can be efficiently manufactured at low cost compared to a conventional cassette, a method for manufacturing the blood component sampling cassette, a blood sampling circuit set and a blood component sampling system. The blood component sampling cassette includes a cassette main body having a plurality of flow paths including an introduction line, a blood component transfer line and a retransfusion line. The cassette main body includes a first sheet and a second sheet which are formed of a soft material compatible with autoclave sterilization. The first sheet and the second sheet are overlaid in a thickness direction and bonded to each other. A plurality of flow paths is formed between the first sheet and the second sheet.

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an interior surface defining an enclosed space, and an exterior surface releasably attachable to a patient. A container may be disposed in the enclosed space and include a reservoir containing a drug and a stopper. A drive assembly may also be disposed in the enclosed space and configured to move the stopper through the reservoir to expel the drug from the reservoir. The drive assembly may include a rotational power source and a gear module. The gear module may include a mounting plate and a plurality of gears rotatably connected to the mounting plate. Furthermore, the mounting plate may be separate from the main housing.

The invention relates to a dialysis device that provides recirculating flow dialysis in a wearable and portable format. It uses an exchangeable purification unit holding a volume of dialysate and/or a sorbent system for the in-situ regeneration of dialysate. The invented dialysis device comprises a carrier that is mounted on a replaceable cartridge. The carrier holds the electronics, user-interface, actuators and sensors. It actuates, controls and monitors the dialysis operation. The cartridge is a replaceable part that is connected to the patient via a flexible tubing. It consists of a reusable housing with a memory chip and holds a disposable inlay containing the purification unit with fluid lines, connectors, dialysate and/or sorbents in combination with a nanofilter. The cartridge is intended for use during the day, as a wearable system. The cartridge can be enlarged with an extension set to offer more capacity. The extended cartridge is intended to be used during the night as a bedside device.
