摘要
An indwelling catheter comprises a catheter tube. The catheter tube is provided with an inserted portion which is to be inserted into a patient and a main portion which is provided on a base end side of the inserted portion. Furthermore, a tapered portion is formed on at least a part of the inserted portion. An outer diameter of the inserted portion is thinner than an outer diameter of the main portion. According to the above-mentioned indwelling catheter, since the outer diameter of the inserted portion is made thinner than that of the main portion by providing the tapered portion, a pricking pain of a patient is reduced. In addition, since the outer diameter of the inserted portion is made thin without the need of making the outer diameter of the main portion thin, a sufficient flow amount of fluid for medical interventions can be secured.
