Abstract

In an injection needle/catheter unit having an internal injection needle, the front end part of the injection needle 1 has a relatively smaller external diameter up until a rear shoulder 1c and the front end part of the catheter 2 has a relatively smaller internal diameter up until a rear shoulder 2c. <IMAGE>

Description

8200138-9 2 partierna âtskiljes av en avsats 2c, som ligger framför ansatsen lc. Partiet 2a är framställt genom kateterformning på en dorn, som har en ansats svarande mot den önskade kateteravsatsen 2c, med hjälp av 5 värme, t ek från varmluft, och en tryckdyna, som får verka mot partiet Za. Andra kända metoder för åstadkommande av avsatsförsedda plaströr eller -slangar, såsom dragning, kan istället.användas. 8200138-9 2 the portions are separated by a ledge 2c, which lies in front of the ledge lc. The portion 2a is made by catheter forming on a mandrel having a shoulder corresponding to the desired catheter ledge 2c, by means of heat, teak from hot air, and a pressure pad, which is allowed to act against the portion Za. Other known methods of making padded plastic tubes or hoses, such as drawing, may be used instead.
