摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, specifically to an intravenous catheter assembly. Assembly comprises: a catheter adapter having a proximal end, a distal end and a fluid chamber extending therebetween； a catheter coupled to the distal end of the catheter adapter, the catheter having a lumen in fluid communication with the fluid chamber of the catheter adapter； a needle adapter slidably positioned within the fluid chamber of the catheter adapter between a distal position and a proximal position, the needle adapter supporting a base end of an introducer needle and a terminal end of a section of intravenous tubing such that a fluid pathway of the introducer needle is in fluid communication with a fluid pathway of the section of intravenous tubing； and a septum interposed between an inner surface of the catheter adapter and an outer surface of the introducer needle. Septum divides the fluid chamber into a distal fluid chamber and a proximal fluid chamber, wherein the inner surface of the catheter adapter further comprises a distal stop for temporarily holding the needle adapter in the distal position during catheterisation. Said distal stop is a protrusion configured for bypassing the needle adapter with a pulling force applied to the intravenous tube in the proximal direction, exceeding the shearing force between the needle adapter and the distal stop.EFFECT: catheterization intravenous access is facilitated between the catheter and the intravenous tubing via the hollow body of the introducer needle.18 cl, 5 dwgИзобретение относится к медицинской технике, а именно к узлу внутривенного катетера. Узел содержит: адаптер катетера, имеющий проксимальный конец, дистальный конец и камеру текучей среды, продолжающуюся между ними； катетер, соединенный с дистальным концом адаптера катетера, причем катетер имеет полость, находящуюся в сообщении по текучей среде с камерой текучей среды адаптера катетера； адаптер иглы, размещенный с возможностью ск
