CATHETER TUBE |
摘要 |
<p>The invention relates to a catheter tube for local anaesthetic with improved characteristics in terms of resistance to kinking, a higher degree of rigidity during application and reduced rigidity after application. According to the invention, said characteristics are achieved by designing the catheter tube as a layered composite tube, whereby the interior that faces the lumen consists of a polyamide layer and the exterior consists of a polyurethane layer. The layer thickness distribution of the polyamide inner layer to the polyurethane outer layer is preferably between 50:50 and 70:30. The inner and outer layers of the inventive catheter tube can be provided with one or more radiopaque strips.</p> |
