  • Patent number: 7713191
    Abstract: A balloon controller for an endoscope apparatus which enables an operator to correctly and immediately grasp circumstances relating to an abnormal condition at the time of occurrence of the abnormal condition. The balloon controller controls expansion and shrinkage of each of a first balloon attached to an insertion portion of an endoscope and a second balloon attached to an insertion assist implement, by supplying air to the balloon or drawing air from the balloon. Pressure indicating portions on which the values of pressures in the first and second balloons are displayed are provided in a front surface of a main body of the balloon controller. When an abnormal condition occurs, an error code and the pressure values are alternately displayed on the pressure indicating portions.

  • Patent number: 7591782
    Abstract: A balloon attaching jig is constituted by a ring member and a pair of nail members. After the insertion of the pair of nail members into an attaching hole of a balloon, the leading end of an insertion portion of an endoscope is pushed into an opening of the ring member. The diameter of the pair of nail members is expanded by a pushing-in force of the leading end of the insertion portion generated during this pushing in. As a result of this, the leading end of the insertion portion is inserted into the attaching hole of the balloon and hence the balloon can be easily attached to the leading end of the insertion portion of the endoscope.
