The present invention relates to a medical tube catheter and to a method for manufacturing same. The medical tube catheter according to the present invention includes PVC resin (polyvinyl chloride resin), a plasticizer, a stabilizer, and NBR (acrylonitrile butadiene rubber). Also, the method for manufacturing the medical tube catheter according to the present invention comprises: a first step of preparing a composition by mixing 80 to 120 parts by weight of a plasticizer, 1 to 3 parts by weight of a stabilizer, and 3 to 20 parts by weight of NBR with respect to 100 parts by weight of PVC resin at room temperature; a second step of blending the composition at 140° C. to 170° C. into a blended compound; a third step of extruding the blended compound through an extruder into a tube shape; a fourth step of cooling the tube; and a fifth step of cutting the cooled tube into predetermined lengths. Accordingly, the product has the economic advantage and good physical properties of natural latex, while having good biocompatibility so as to prevent various allergies and side effects from toxins. Also, by adding NBR, elasticity is imparted and flexibility is improved, and slippage is improved so that insertion in and removal from the body is made easy and damage to a mucous membrane from stickiness can be prevented. |
