Abstract: A device for administering an infusion or transfusion of liquid from a container includes a pump for pumping liquid to a patient connection via a conduit having a liquid-retaining filter membrane. The device also includes a pressure measuring device for acquiring measurement values corresponding to a pump-inlet-side pressure, and a control device for detecting a change in the pump-inlet-side pressure based on the measurement values. The control device determines, based on the change in the pump-inlet-side pressure, whether to stop pumping. The control device also generates a control signal when the pumping is to be stopped. Moreover, the control device emits, based on the control signal, a communication signal to a data connection between the device and a unit that reads the communication signal. In addition, or in the alternative, the control device switches the device from a first state to a second state based on the control signal.

Abstract: An infusion or transfusion set for administering a liquid from a container using a pump. The infusion or transfusion set includes a branch that provides a fluid connection between a first supply line, a second supply line and a discharge line. The first supply line includes a liquid-retaining filter membrane having a breakdown pressure. At least the second supply line has a check valve. The check valve is opened for fluid passage in the direction towards the branch if the pressure difference at the check valve is greater than a threshold value that is less than the breakdown pressure of the liquid-retaining filter membrane.

Abstract: A clamping module of or for a medical pump, and a method for identifying a hose clamp of a disposable infusion article insertable into the clamping module. The clamping module includes an electro-optical system for identifying the hose clamp, which has an optical marking. The electro-optical system includes a first light source for emitting at least a first light beam and a second light source for emitting at least a second light beam. The second light source is formed differently than the first light source. A photodetector receives a reflected light, and an optical window bundles the first light beam and/or the second light beam on the disposable infusion article, as well as the reflected light received by the photodetector. The method identifies the hose clamp based on a color and uses a measurement algorithm after insertion of the hose clamp into the medical pump.

Abstract: A medical infusion system includes a hose line with a distal end region for connection to an infusion reservoir and a proximal end region that has a patient connection port. The patient connection port has a closure device with an air-permeable and liquid-tight design. The system can be used in the medical sector for intravenous medication.

Abstract: A medical pump, in particular an infusion pump for conveying a medium, includes a seating for a hose clamp which is separate from the pump and arranged on the hose. Two clamping portions of the hose clamp which can be moved relative to each other can be transferred into a closed relative position in which they pinch off the hose arranged therebetween in such a manner that it is not possible for any medium to flow through the interior of the hose. Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.

Abstract: A connector device for a fluid system for medical purposes is disclosed that includes a main housing having a fluid flow chamber forming two channel portions leading in different directions towards two open attachments, wherein the attachments are provided for connection to a fluid line or a fluid reservoir, and with an attachment port which opens into the fluid flow chamber and which has a closure arrangement and which includes a Luer connecting portion. The fluid flow chamber has a dimensionally stable flow-guiding wall which is arranged between the two channel portions in the fluid flow chamber and protrudes freely with a front edge towards the attachment port in such a way that the closure arrangement, upon opening of the closure arrangement, interacts with the front edge of the flow-guiding wall in order to effect flow of fluid out of the attachment port into only one channel portion.

Abstract: Apparatus enables one or more needleless injection ports to be established on IV tubing as needed. An IV tubing-engaging portion secures the apparatus about the tubing. A puncturing member establishes fluid communication between the IV line and a sealing member on the apparatus. Connecting a syringe to the sealing member establishes fluid communication between the IV line and the syringe, enabling an injection to be made. When the syringe is withdrawn, the sealing member reseals to prevent fluid leakage from the IV line.

Abstract: The various embodiments include a tubular member having an outlet. A sealing member provides a selective seal over the outlet. When the male connector is connected to a female connector, the tubular member establishes fluid communication between the connectors. In certain embodiments, fluid communication between the connectors may be interrupted even while the connectors are still connected. When the male connector is disconnected from the female connector, the sealing member reestablishes a seal over the outlet.

Abstract: A method for quantitative and/or qualitative determination of germs in a liquid sample comprises the steps of: (1) passing the sample through a filter thereby depositing the germs on a major portion of the filter so that a minor portion of the filter is free of germ deposits; (2) applying a fluorescent label to at least a portion of the deposited germs; (3) determining the presence and/or the amount of labeled germs by fluorescent reflection photometry. The method according to the present invention is suitable, for example, for quantitative and/or qualitative determination of germs in foodstuffs, surfactant-containing products such as washing and cleaning agents, surface treatment agents, dispersion products, cosmetics, hygiene products and personal care products, pharmaceuticals, adhesives, coolant lubricants, coatings and coating coagulations, as well as raw materials and starting materials for the aforesaid products.

Abstract: The invention relates to a lid element which is placed on cell culture vessels in which cells contained in a liquid medium are accommodated. The lid element according to the invention is intended to allow determination of metabolism activities of cells which are contained in the cell culture vessels, by means of optical measurement methods, which can be carried out with simple handling by means of laboratory personnel. Light-guiding elements are provided on the lid element which can be fitted to the cell culture vessel and, when the lid element is fitted, project into the interior of cavities in the cell vessel. At least one optically sensitive layer is formed on one end surface and/or on the outer envelope surface of the light-guiding elements, which are preferably optical waveguides in the form of rods, for detection of chemical substance concentrations which change within the cavities.

Abstract: The invention relates to a method for monitoring metabolic activity of cells in liquid media, to an appropriate vessel and to a device for implementing said method. The invention aimes at enhancing measuring accuracy and reducing the costs involved in monitoring oxygen consumption and thus metabolic activity in culture cells. To this end, oxygen concentration is optically determined with the aid of sensor membranes in a liquid medium located in partially oxygen permeable vessels. Then, the measured oxygen concentrations in the vessels containing culture cells in a liquid medium are compared with the measured oxygen concentration in a vessel containing only such a liquid medium without cells and/or with an oxygen concentration calculated using the measured values of other parameters.
