摘要： The invention relates to an air trap for shutting off plastic tubes, especially infusion tubes, which reliably ensures, for example in blood transfusions, automatic discontinuation of the blood supply when air bubbles reach the infusion tube. For this purpose, the air trap for shutting off plastic tubes, especially infusion tubes, possesses a mushroom head which rests under the action of a spring against the membrane - Teflon membrane - of a pressure chamber, on the one hand, whereas a pressure ram which is under a weaker action of a spring rests against the membrane in the pressure chamber, on the other hand. The pressure ram reaches into a tube passage so as to provide a seal - an annular seal - such that the tube passage is open when the chamber is under gas pressure and is squeezed by the pressure ram when the chamber is not under pressure.

摘要： Clamping device for the elastic compression of tubular parts, in particular for use in medicine for clamping blood vessels, urethras and the like. Devices used in the medical sector have a U-shaped carrier with elastically bendable legs onto which a clamping piece is pushed. When the clamping piece is positioned, the carrier legs are bent elastically, a clamping action being achieved between them and the clamping piece. The clamping piece can, however, be displaced unintentionally on the legs. In the case of the novel clamping device, the intention is that the clamping piece cannot be displaced unintentionally on the carrier legs. The carrier legs are provided with latching members to which there is assigned, on the clamping piece, at least one counter-latching member. The clamping piece and the carrier legs are connected to one another in a positively locking manner via the latching and the counter-latching members, with the result that the clamping piece cannot slide unintentionally out of its clamping position. Use in the medical sector for clamping the urethra in male patients.

摘要： Manually overridable servo controlled valve mechanisms for controlling the flow of fluids through a flexible tube for use in a photoactivatable agent treatment system wherein photoactivatable agents, in contact with patient blood cells, are irradiated extracorporeally and then returned to the patient.
