Abstract

The invention discloses an intrusive medical catheter with markers and a manufacturing method of the intrusive medical catheter. The medical catheter comprises a marker layer and a contact layer which are in closed combination. The marker layer having photosensitiveness is provided with photosensitive marked patterns; the contact layer is transparent and refers to a compatible polymeric material layer. The manufacturing method includes firstly, preparing the material of the marker layer on site; secondly, subjecting the base materials of the marker layer and the compatible polymeric material layer of the contact layer to extrusion molding simultaneously; thirdly, curing the marker layer and the contact layer obtained in the second step; fourthly, by laser, carrying out photosensitive marking to a prefabricated catheter obtained in the third step. The catheter has the patterns highly recognizable, has no risk of coming off of ink, and has smooth surface and good biological compatibility. The manufacturing method is applied to manufacturing intrusive medical catheter with high-precision patterns.

Description

technical field

[0001] The invention belongs to the field of medical devices, and more specifically relates to a markable interventional medical catheter and a preparation method thereof. Background technique

[0002] Interventional medical catheter is an important device in the field of interventional medicine. Precision medical catheters can constitute independent interventional medical devices, and can also be used as components of interventional medical devices, such as balloon dilatation catheters, central venous catheters, micro-floating catheters, trocar peripheral catheters, ablation catheters, and interventional sensing and measuring catheters Wait.

[0003] Interventional precision medical catheters have the characteristics of small size and precise structure, and they need to have smooth and flat surfaces and good biocompatibility. Some of the catheters need to form clearly identifiable marks to judge the position or measurement, or form various text symbol info...
