  • Publication number: 20180333076
    Abstract: A breathing tube for use in lung function diagnostics comprises a breathing tube body having first and second windows. The first window allows ultrasonic waves to pass from an exterior to an interior of the breathing tube body and vice versa, and the second window allows ultrasonic waves to pass from an interior to an exterior of the breathing tube body and vice versa. First and second sealing elements circumferentially extend around the breathing tube body on its outside and define a first breathing tube body section located between the first and second sealing elements, in which the first and second windows are located. At least one of the first and second sealing elements includes a first groove, a second groove, and a sealing lip located between the first groove and the second groove, which protrudes over a surface of the breathing tube body.

  • Patent number: 5683658
    Abstract: A reagent bottle suitable for insertion into a sample analyzer features a sample discharge opening plugged by an elastic, pierceable stopper, and an air inlet. Both the sample discharge opening and the air inlet are located on the same side of the reagent bottle, the axes of the two openings running parallel to each other, such that both openings can be docked onto corresponding sampling and air inlet elements of the analyzer in one and the same working process when the reagent bottle is inserted into the analyzer. The elastic stopper is covered on its outside by a protective foil and has a recess at a puncturing site enabling the sampling element to puncture the foil more easily. Bordering on the recess of the stopper is an area which is prepunctured but offers a tight elastic seal.

  • Patent number: 5441701
    Abstract: A feeder unit, which is used for selectively charging an analyzing apparatus with liquid or gaseous sample-, reference- or cleaning media, comprises a sample inlet and a feeder part hinged on the feeder unit at one end. The feeder part contains an intake passage for the cleaning medium to be entered, the sample inlet having a flexible feeder funnel cooperating with a washing element which is attached to the feeder part and can be introduced into the funnel. The feeder part is configured as a cover flap swinging around a fixed pin. The intake passage for the cleaning medium opens into the washing element and is also used for delivering liquid and gaseous reference media. The washing element is located on a support which is elastically attached to the cover flap, and fits into the flexible funnel when the cover flap is closed.

  • Patent number: 5372582
    Abstract: A dialytic probe is provided with an insertion needle sharpened at one end, which is surrounded by a flexible plastic cannula, and may be removed after introduction of the probe. The plastic cannula is covered at least partly by a tubular dialyzing membrane which is bonded to the plastic cannula at the distal end and to a handle at the other end, thus forming a fluid-tight seal. The space between the plastic cannula and dialyzing membrane is divided along the length of the probe, such that two passages or lumens of essentially crescent-shaped cross-section are formed, with a flow-connection at the distal end of the plastic cannula, and with a connection to one of separate ingoing and outgoing lines each. The lumen of the plastic cannula may be connected to a drug feeder line. The handle holds the ingoing and outgoing lines and a potential drug feeder line of the probe.
