Question 12

coude vs tieman tip catheter

Answer 12

What is the difference between Coude Tip and Tieman Catheters?
The Coudé tip catheter has a curved tip like the Tiemann catheter but has one or two drainage eyes situated in the curved tip.

Question 13

What are the different materials catheters are made of

Answer 13

Latex
PTFE/Teflon coated latex catheters
Silicon coated latex catheters
Silicone (100% silicone)
Hydrogel coated
Silver-hydrogel coated catheters made of latex or silicone
Nitrofurazone-coated catheter

Question 14

How is catheter size measured?

Answer 14

The French size is three times the diameter in millimeters. Thus, the French size is roughly equivalent to the circumference of a circular catheter; the true circumference being slightly larger (circumference = diameter * π where π is approximately 3.14).

A round catheter of 1 French has an external diameter of 1⁄3 mm,[2] and therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3:

1 mm = 3 Fr
1 Fr = 1/3 mm
For example, if the French size is 9, the diameter is 9/3 = 3.0; mm.

Question 15

catheter colour codes

Answer 15

white 12
black 10
purple 8
green 14
orange 16
red 18
yellow 20
purple 22

Question 16

Do you think there is co-relation between size in French and internal diameter of the lumen?

Answer 16

The inner lumen of the catheter varies quite a lot between different catheter materials e.g. Silicone has wider while latex narrower lumina.

Question 17

length of catheter

Answer 17

Length of male catheter- 41-45 cm

Female-25 cm
