同義詞

  • drain

用法筆記

Frequently used in hospital settings. The verb form 'to catheterize' refers to the act of inserting a catheter. When discussing removal, common phrases are 'the catheter came out' or 'the doctor removed the catheter.' Never force or pull a catheter — this can cause injury.

常見錯誤

The doctor put a catheter in the patient's heart.
The doctor placed a catheter in the patient's bladder to drain urine.
A urinary catheter goes into the bladder, not the heart. Cardiac catheters exist but are much less common and go into blood vessels near the heart.
He catheter fell out.
His catheter came out.
'Catheter' is a countable noun; use the correct possessive or article.
I need to change my catheter every hour.
A urinary catheter is usually changed every few weeks by a healthcare professional.
Catheters are not changed hourly; the drainage bag may be emptied more often.
