Locking device of the tubes or flexible pipes used in installations enteral to the power supply and / or parenteral or the circulating extracellular body -

摘要

Coupling for flexible tubes employed in medical applications such as enteral/parenteral feeding, extracorporeal circulation of blood etc. The coupling is for twin path, parallel flow through two coupled pairs of flexible tubes. The coupling comprises two flat, superimposed plates which are clamped or clipped together. Two leakproof joints between the two pairs of tubes are made in two passages through the superimposed plates by the action of clamping the plates together. In partic. the coupling is used to join suction and delivery tubes to the inlet and outlet ends of a flexible tube element of a peristaltic pump stops are provided to hold the coupling plate stationary when the inlet end of the peristaltic element is pulled by pumping action. The peristaltic tubular element is pref. made of silicone rubber and the suction and delivery tubes of PVC. Used for joining flexible tubes employed in parenteral feeding or extracorporeal circulation of blood during, e.g. surgical operations on heart, lungs, kidneys, etc. Quick action, simple non-slip system has perfectly sealed joints, partic. suitable for coupling to the element of a peristaltic pump.
