< Objective >The flexible tube is kept and at the same time the blockade for flow in the device in order to change the direction, in the bending section of the flexible tube is prevented, in addition, making use of part such as the connector which contacts with the fluid pollution of the fluid is prevented the flexible tube itself as mode of transportation by using.< Constitution >The improved tube device which is suited for the use in medical field (30) is offered. This tube device uses the flexible tube itself contacts with the fluid and as mode of transportation, making use of part such as the connector which is converted damp, the traffic channel which does not have connection (32) gives, makes the number of fluid electro-mechanicals component decrease, cuts the tube to the plural sections and removes the necessity which afterwards is connected with the connector. Because of this risk of pollution of the transport substance is lightened, also use of chemicals such as adhesive may be little and.【目的】可撓管を保持し且つその向きを変えるための装置において、可撓管の曲がり部において流動に対する閉塞を防止し、また、流体と接触するコネクタなどの部品を用いず可撓管自体を輸送手段として用いることにより流体の汚染を防止する。【構成】医学分野での使用に適した改良型管装置(30)が提供される。この管装置は、可撓管自体を輸送手段として用い、流体と接触して湿潤化されるコネクタなどの部品を用いずに、継ぎ目のない輸送路(32)を与え、流体接触部品数を減少させ、管を複数部にカットして後にコネクタで連結する必要性を排除する。これにより輸送物質の汚染のリスクが軽減され、接着剤などの化学剤の使用も少なくて済む。
