摘要： A bypass for power injection includes (a) a housing (100) defining a lumen (108) extending from a proximal end to a distal end coupled to a catheter; (b) a membrane valve (110) mounted within the lumen, the membrane valve having an opening (112) extending therethrough sized to tightly receive therethrough and seal around a power injection device (130); and (c) a flapper valve (120) extending across the lumen distally of the membrane valve. The flapper valve includes a flap biased toward a closed position in which the lumen is sealed. The flap is rotatable away from the closed position when contacted by a power injection device to permit the device to extend therethrough.

摘要： The invention relates to a one-way valve device (1), in particular a low-pressure non-return valve for use with infusion equipment. Said device consists of a housing (2, 3) comprising a supply tube (5) and a drain tube (14), in addition to at least one seal (4) that is enclosed in a pressure chamber (12). To prevent the admission of air into the infusion liquid circuit, the flow is interrupted by a static negative pressure prevailing on the supply tube (5) and/or drain tube (14) or by an excess pressure on the drain tube (14). This reliably guarantees that the infusion liquid only circulates if there is a static excess pressure on the supply tube.

摘要： An anti-siphon control valve including a housing fitted with a first port inflow, being in fluid communication with a first chamber, and a second port outflow, being in fluid communication with a second chamber coaxial with the first chamber. A fluid flow path extends between the chambers. A resilient membrane is tensioned over the fluid flow path and over chamber so as to close the fluid flow path. The membrane has one face exposed to atmospheric pressure. The arrangement is such that when differential pressure across the membrane exceeds predetermined pressure threshold the membrane flexes and opens the fluid path allowing fluid flow between the first chamber and the second chamber.

摘要： A catheter (10) and catheter assembly (2) are disclosed comprising a urinary catheter (10) comprising an insertion end (14), a rearward end (11), and a one way check valve arrangement (15). The check valve arrangement comprises a tubular part of a flexible material (15), connected to the rearward end (11) of the catheter and extending past the rearward end in a direction opposite to the insertion end (14), thereby substantially limiting the flow through the catheter to a single direction from the insertion end to the rearward end. Hereby, a very effective anti-reflux function is achieved, and at the same time the construction is relatively simple and inexpensive, and does not require any essential modifications of the other parts of the urinary catheter.

摘要： A medical device such as an ostomy appliance (10) has an inflatable seal (12) for sealing an opening in a patient's body. A non-return valve is provided at an inlet port (22) for admitting inflation fluid into the inflatable seal and for preventing escape of the inflation fluid. The non-return valve comprises a film panel (26) having a first portion (26a) attached to a wall portion (27), and a second portion (26b) that is unattached to the wall portion to provide a valve function. The second portion (26b) lifts from, or seals against, the wall portion (27) in response to a differential fluid pressure acting on the second portion. The wall portion (27) may be a second film panel (28), or an underlying substrate (26).
