Abstract: PURPOSE: To keep a sensor for detecting an in-blood gas in a sterilized atmosphere, and insert the sensor and its signal line through a catheter. CONSTITUTION: A device comprises a cylindrical housing 22 to the tip of which a catheter 14 is connected, and its inside is kept in a sterilized atmosphere, and a medical equipment is stored therein. After the catheter 14 is connected to the tip of the housing 22, the device can be moved through the catheter 14. An externally deflecting flexible sleeve 34 is stored in an annular space between the housing 22 and a signal line 16, a sensor 12 is placed in the sterilized atmosphere, and when a medical equipment is advanced from the housing 22 to the catheter 14, a sleeve 34 is folded by itself to keep the sterilized atmosphere. When a non-sterilized part of the signal line 16 is inserted in the housing 22 as the signal line 16 is introduced into the housing 22, the sleeve 34 is not polluted through the sterilized atmosphere in the housing 22 is polluted.
