摘要： A combination filter assembly having a plurality of filter sieves positioned in parallel one after the other in the direction of flow. The filter sieves are stretched and mounted in housing elements to form filter elements. The housing elements are in contact with each other by means of top and bottom bearing faces, and are maintained in a stack. The filter elements have a cylindrical shape with annular bearing faces, wherein one bearing face includes a centering male coupling and sealing formation, and the other bearing face includes a corresponding centering female coupling and sealing formation.

摘要： An apparatus for the transmission of the pressure in the sterile area of a medical appliance to a non-sterile pressure gauge has two housing halves and a sterility filter positioned between the two housing halves. The filter is supported by a backing. The housing half on the sterile side is made of polycarbonate. The non-sterile half of the housing is made of a polymer, preferably a polyester/polyether copolymer, which provides an easily disconnectable and leak-proof connection with the pressure gauge. The two halves are ultrasonically welded together.

摘要： In an infusion set having a container for fluid medicines, which by a feed-line and a differential pressure valve is connected to a drip chamber and which by a further feed-line is connected to a front end controlled with a roller clamp according to U.S. patent application Ser. No. 08/800,779, the differential pressure valve has two inlets each with an associated differential force chamber and the two differential force chambers are sealingly separated from each other by a diaphragm disk, wherein both differential force chambers are connected to an exit line for the fluid medicine. To use the differential pressure valve, the valve is configured as a 3-way check valve by the fact that the first inlet is connected to the container for the fluid medicine and that the second inlet is designed for the connection to a syringe or the like.

摘要： A method and infusion set for consecutively draining liquid medicines from a plurality of containers, such as two containers (1, 2) containing said liquid medicines, the liquid medicine via a differential pressure valve (5a) is fed into a drip chamber (6), wherein the fluid flow is permitted initially from one container (1) by the higher fluid pressure and differential force area from the first container (1) on a diaphragm disk (15), whereby the fluid flow from the second container (2) is stopped and, later an automatic switch to a second container (2) as a source of fluid is effected when the fluid flow from the almost drained first container (1) is at a lower fluid pressure and a smaller differential force area and is exceeded by a higher fluid pressure of the second container (2) and the larger differential force area.

摘要： A check valve, especially for the medical technique having a first hose connector housing (1) and a second hose connector housing (2) and further a flexible diaphragm disk (3) positioned between the two joined hose connector housings (1, 2). At an overpressure in an entry space (6) the diaphragm disk (3) can be lifted from a lip-shaped sealing ring (13), whereby a flow cross-sectional area is created, and wherein the diaphragm disk (3) at an overpressure in an exit space (7) safely and in minimal times can be pressed onto a sealing seat to close the valve. The circular diaphragm disk (3) is produced from liquid silicone, silicone rubber or natural rubber and the thickness (3c) of the diaphragm cross-section (3a) is uniform.
