Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of tips for foley's tube.
Background technique
In existing foley's tube product, in order to make conduit cause lesser injury in human vas, in the remote of conduit
End is welded with tip.Tip is usually made of softer material, such as rubber, polytetrafluoroethylene (PTFE) (poly tetra
Fluoroethylene, PTFE), polyimides (Polyimide, PI) be either mixed into metal powder (such as tungsten powder) in rubber,
The hardness range at tip is 10A-30D.
In order not to same functional requirement, such as anti-buckling strength at reinforcement tip and anti-cut stress intensity, can change in tip
Material component and ratio, with realize catheter tip it is a softer and smoother touch with it is durable etc..
In order to improve the firmness at tip and conduit, usually welds etc., distal end of catheter is enable to merge with tip
Together.
But the material at existing tip mainly selects high molecular material or is mixed into metal powder in high molecular material, this
Although kind of composition component can be improved the durable tolerance at tip, fatigability intensity and transverse strength etc., but the use at tip
Service life is still lower.In addition, pipe walls support power is poor since tip is softer, it is easy stress deformation, card seal wire problem easily occurs,
Influence procedure.
In addition, in the course of surgery, since tip contacts lesion locations at first, so that tip has higher probability to be stuck in
Tip is extracted or is rotated outward if applying biggish strength by lesion locations, it may appear that the problem of tip is separated with distal end of catheter,
And then tip is made to stay in the body, cause danger；When swapping seal wire operation during surgery, tip is easy damaged or is torn,
Cause conduit scrappage higher, improves medical treatment cost.
Therefore, it needs one kind to improve service life, improves the tip of intensity, to reduce the scrappage of conduit, reduce doctor
Treat cost.
