Foley Catheter Tip forming Machine

Foley catheter belongs to the second category of medical machinery, is a kind of tube inserted into the bladder by the urethra in order to drain urine, mainly used for urinary retention or bladder outlet obstruction, urinary incontinence, need to be bedridden for a long period of time or forced position, perioperative surgical patients use.

Foley Catheters are usually divided into 13 sizes and models according to the circumference of the outer diameter, ranging from 6F to 30F, and the four commonly used catheters for adults are 12F, 14F, 16F, and 18F.

What are the materials of Foley catheters?

Foley Catheters are mainly made of polyvinyl chloride, silicone, latex, etc. The characteristics of catheters made of different materials vary:

  • Polyvinyl chloride (PVC): the product is harder, more irritating, strong foreign body sensation, inexpensive, mostly without air bladder products, and poor biocompatibility, easy to occur adhesion, can be left in a short period of time.
  • Dry rubber (raw rubber): the product is softer, more irritation, the patient feels uncomfortable, long time use can easily lead to catheterization mucosa inflammation, and easy calcium, but the price is low, mostly for the product without airbag.
  • Silicone: the product is softer, almost no irritation, biocompatibility, the patient has no foreign body sensation, silicone catheter inner diameter is wide, suitable for long-term indwelling catheterization, can avoid multiple insertion, reduce friction with the urethra, reduce the patient’s pain and reduce the incidence of urinary tract infections. But the molding process is not easy to keep the surface clean, high cost, mostly without airbag products.
  • Latex: soft, biocompatible products, the patient feels comfortable, high surface finish, irritation is very small, the price is appropriate, mostly for the balloon products, easy to leave the operation, and can be short-term indwelling catheterization, but the texture is soft, it is difficult to smoothly inserted into the bladder, easy to sink calcium clogging, and cytotoxicity reaction.

Process of innovation

With the continuous development of production technology, the catheter has undergone a change from traditional, modernized to fully automated production process. Nowadays, more and more automated equipment and precision equipment are applied to the production of catheters. CatheterMelt PVC catheter tip molding machine without flying edge, the yield rate is up to 99%, with high compatibility so that the size and length can be produced according to the needs of the high-frequency melting head to make the tip of the catheter molding more round and smooth.
