Uterine hemostatic balloon unit

A uterine hemostatic balloon unit comprising:

• a flexible tube;
• a hemostatic balloon disposed in a distal end portion of the flexible tube;
• a connector disposed in the flexible tube;
• and
• a cap to be detachably attached to a proximal end portion of the flexible tube,
• wherein the flexible tube has
• a drain channel for draining uterine blood outward by being open on a distal end side from the hemostatic balloon, and
• a water supply channel communicating with the hemostatic balloon, wherein the connector has
• a drain terminal communicating with the drain channel and disposed in a proximal end portion of the flexible tube,
• a flexible water supply tube communicating with the water supply channel on a distal end side from the drain terminal and extending by being bifurcated outward of the flexible tube, and
• a water supply terminal disposed in a proximal end of the water supply tube and communicating with the water supply tube,
• wherein the cap detachably fits to an opening of the drain terminal and has an accommodating portion capable of accommodating at least a portion of the water supply terminal along a length direction of the drain terminal, and the accommodating portion is open in a direction orthogonal to the length direction of the drain terminal, and
• wherein the accommodating portion has a stopper portion which regulates movement of the water supply terminal in the direction orthogonal to the length direction of the drain terminal, and the stopper portion has a projection which projects from a surface on a side opposite to the drain terminal side in the accommodating portion so as to be fitted into an opening of the water supply terminal, when the water supply terminal is accommodated inside the accommodating portion.

A uterine hemostatic balloon unit comprising:

• a flexible;
• a hemostatic balloon disposed in a distal end portion of the flexible tube
• a connector disposed in the flexible tube;
• and
• a cap to be detachably attached to a proximal end portion of the flexible tube, wherein the flexible tube has
• a drain channel for draining uterine blood outward by being open on a distal end side from the hemostatic balloon, and
• a water supply channel communicating with the hemostatic balloon, wherein the connector has
• a drain terminal communicating with the drain channel and disposed in a proximal end portion of the flexible tube,
• a flexible water supply tube communicating with the water supply channel on a distal end side from the drain terminal and extending by being bifurcated outward of the flexible tube, and,
• a water supply terminal disposed in a proximal end of the water supply tube and communicating with the water supply tube
• wherein the cap detachably fits to an opening of the drain terminal and has an accommodating portion capable of accommodating at least a portion of the water supply terminal along a length direction of the drain terminal, and the accommodating portion is open in a direction orthogonal to the length direction of the drain terminal,
• the uterine hemostatic balloon unit further comprising a stylet fixed to a distal end side of the cap and holding a shape of the flexible tube when the stylet is inserted into the flexible tube, wherein when the cap is mounted on the opening of the drain terminal, a distal end of the stylet is located in a portion from a proximal end portion of the hemostatic balloon to a center of the hemostatic balloon.
