Abstract

The invention discloses a dilation balloon catheter for a pathological change of a narrow digestive tract. The dilation balloon catheter comprises a balloon, wherein a catheter is arranged inside theballoon, the balloon is formed through combining a corrosion-resistant film, a stretching film and a nylon layer which are arranged sequentially from top to bottom, the corrosion-resistant film is formed through combining an upper-layer PET film, an aluminum coating, an anti-reflecting film, a lower-layer PET film and an EVA adhesive film which are arranged sequentially from top to bottom, and thestretching film is formed through combining a heat-insulating film, a transparent layer, a film layer, a transparent adhesive layer and a release film which are arranged sequentially from top to bottom. According to the dilation balloon catheter, the problem that only fuzzy narrow length and distance of the digestive tract can be judged when the existing dilation balloon catheter is used by working personnel is solved, the stability and accuracy are improved, the bendability and tensile and dimensional stability are further improved, and the practicability is high.

Description

Technical field

[0001] The invention relates to the technical field of a digestive tract stent catheter, in particular to a dilatation balloon catheter for narrow digestive tract diseases.Background technique

[0002] With the changes in life and diet and the impact of the environment, the incidence of people's intestinal diseases has greatly increased. At present, interventional radiology treatment of gastrointestinal stenosis can be treated with permanent upper gastrointestinal stent placement, temporary gastrointestinal stent placement, and simple balloon dilatation. The application of dilatation balloon catheter technology to the treatment of the gastrointestinal tract provides a new solution to the restriction of the stricture of the gastrointestinal disease environment. The traditional dilatation balloon technology is likely to cause restenosis of the upper digestive tract. Based on this, preparing a dilatation balloon catheter suitable for narrow digestive tract lesions has become ...
