Composition for catheter and production method therefor

Abstract

The present invention relates a composition for producing a foley catheter which is inserted in vivo and a method for producing the same, which the composition consists of the materials which carbon nanotube polymer (CNT Polymer) bonded a carbon nanotube and zinc oxide (ZnO) is combined with a silicon, wherein from 1.0 to 2.2 parts by weight of the said carbon nanotube polymer are combined with 100 parts by weight of silicon.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a composition for producing a foley catheter which is inserted in vivo and a method for producing the same.Description of the Prior Art[0002]In general, patients with systemic or lower body paralysis caused by cerebral diseases such as stroke or spinal injuries are increasing year by year due to an increase in the elderly population and an increase rapidly in traffic accidents or industrial accidents.[0003]A bladder paralysis is inevitably accompanied in such patients. A treatment of bladder paralysis is entirely dependent on the prognosis of the patient, and a foley catheter is maintained in the bladder as a treatment for these patients.[0004]The foley catheter is made by attaching a foley to the distal end portion of the tubular catheter body so that the foley is expanded by the fluid introduced from the outside to have a balloon shape, which the catheter is held in the bladder.[0005]In the cas...

AI Technical Summary

Benefits of technology

This patent is about a new composition and method for making a foley catheter that has better antibacterial properties and can maintain them for long periods of use. The composition uses carbon nanotube polymer that is able to inactivate bacteria while still having a beneficial effect on the body. The foley catheter made with this composition does not have any side effects like resistance to antibiotics and is comfortable to wear for extended periods of time. It also has high thermal conductivity which helps to reduce patient discomfort during insertion and minimizes the need for additional replacement catheters due to infection.

Problems solved by technology

A bladder paralysis is inevitably accompanied in such patients.

Although antibiotics are initially effective in antibiotics, biofilm formation is occurred inevitably due to the intubation of the urinary tract for more than from 2 to 3 days according to the nature of the catheter.

Such biofilm formation may cause the antibiotic effect of the foley catheter to decrease or disappear so that there is a problem that the complications such as urinary tract infection is resulted and treatment for this should be accompanied and the length of hospital stay is prolonged.

In addition, since the antibiotic drugs or substances applied to the surface of the conventional foley catheter are always held in the fastening state, the urinary tract infections and stones are formed, resulting in kidney failure in 40% of the total patients, which is the greatest cause of death.

However, there has been a problem that the antibacterial activity is decreased due to peeling of the coated antibacterial substance when used over a certain period of time.
