摘要： A medical connector link for establishing a fluid connection between two fluid lines includes a first male link element/connector element and a second female link element/connector element. The male link element is arranged or arrangeable in the female link element such that a fluid passage of the male link element and a fluid passage of the female link element form a common fluid passage. The connector link further includes a seal element arranged within a circumferential groove on an outer side of the male link element or on an inner side of the female link element. The seal element seals a radial gap between the female link element and the male link element. The male link element and/or the female link element have at least one recess that fluidically connects the common fluid passage with the circumferential groove.

摘要： A peristaltic pump includes a housing and a rotor that rotates about a rotor axis. The rotor has a rotor body and a pump. The housing has a cut-out in which the rotor is accommodated and a support surface extending about the rotor axis. The support surface supports a tube segment that is introducible between the rotor and support surface. The rotor has a first element for manually actuating the rotor and a first portion for applying a manual rotation actuation force. The first element is mounted on the rotor body and is movable relative to the rotor body between a first position, in which the first portion is spaced from the rotor axis by a first length, and a second position, in which the first portion is spaced from the rotor axis by a second length, the second length being greater than the first length.

摘要： A display device of a dialysis machine for displaying various parameters containing a quantity of patient-related treatment parameters and a quantity of clinic-related CIS parameters. The display device has one display and an input unit to individually modify the quantity of patient-related treatment parameters or the quantity of clinic-related CIS parameters. The display includes a display area divided into a first display panel and a second display panel. The display can be switched to a treatment configuration in which the quantity of patient-related treatment parameters is displayed exclusively in the first display panel and the quantity of clinic-related CIS parameters is displayed exclusively in the second display panel. The display can also be switched to a CIS configuration in which the quantity of patient-related treatment parameters is displayed exclusively in the second display panel and the quantity of clinic-related CIS parameters is displayed exclusively in the first display panel.

摘要： A pressure-measuring assembly for measuring the internal line pressure of a line system of an extracorporeal blood treatment machine. The assembly includes a pressure sensor that is connectable to a pressure receiver by a rigid, bending-resistant fluid line. The pressure receiver is connected or connectable to the line system. The pressure sensor converts a fluid pressure signal from the fluid line into an electrical signal. An electrical line connects the pressure sensor to electronics to process the electrical signal. A retainer directly or indirectly retains the pressure sensor and forms, at least in parts, an inner channel, in which the electrical line is led. Alternatively, the retainer is a substantially plastically curvable bar which has, at one axial end portion, a fastening device for mounting on a stationary base and, at the other axial end portion, an articulation site for the pressure sensor or the pressure receiver.

摘要： A holding device for holding and fixing at least one electronic terminal device, in particular of the entertainment electronics type, during a medical treatment, more particularly dialysis treatment. The terminal device is or can be attached to a medical treatment apparatus, such as a dialysis machine, or to a patient bed. The holding device includes an integrated charging unit to supply the held and/or fixed electronic terminal device with power, more particularly from the medical treatment apparatus, with a protection circuit being integrated in the holding device to detect a defect of a terminal device that has just been connected. A charging unit includes an integral power supply unit on a dialysis machine or patient bed having a holding device.

摘要： A dialyzer for an extracorporeal blood treatment includes an elongated, preferably cylindrical dialyzer housing, and at least one dialysis membrane that separates an internal space of the dialyzer housing into a dialysis liquid chamber and a blood chamber. The dialysis liquid chamber has a dialysis liquid supply port and a dialysis liquid discharge port. The blood chamber has a blood supply port and a blood discharge port. The dialyzer includes an additional ventilation outlet for ventilating the blood chamber. The additional ventilation outlet is located with respect to a blood flow direction in the blood discharge port between an exit area of the blood discharge port and the dialysis liquid supply port. A corresponding dialysis device includes a ventilation outlet on a dialyzer housing or on a hose connected to a blood discharge port.

摘要： A device and method are used for monitoring an extracorporeal blood treatment device, such as a dialysis machine, which includes an extracorporeal blood circuit having an arterial blood line with an arterial patient port and/or at least one venous blood line with a venous patient port, and a dialysis fluid system which has a dialysis fluid supply line and a dialysis fluid drain line. The monitoring device selects and senses a measured value during operation of the extracorporeal blood treatment device which is suitable for monitoring the blood treatment device to compare a time-related actual course of the measured value with a target course of the measured value stored in a memory, and to determine that there is a defect if, at least in sections, the actual course of the measured value deviates from the target course by more than a defined tolerance.

摘要： A method and apparatus for priming an extracorporeal blood system. The extracorporeal blood system includes an arterial blood line, a venous blood line, a pump segment for interaction with a peristaltic blood pump of the apparatus and a blood treatment unit. A port of the venous blood line is connected to a venous blood port of the blood treatment unit. A port of the arterial blood line is connected to an arterial blood port of the blood treatment unit. The extracorporeal blood system is connected to a reservoir containing priming liquid. The non-occluded extracorporeal blood system is subsequently filled with priming liquid and, after filling with priming liquid, the pump segment is automatically occluded by a blood pump.
