FIELD: medicine. ^ SUBSTANCE: invention concerns medicine. The device includes a plastic catheter and restrictor. The catheter is executed in the form of the tube having two channels unconnected among themselves, one of them is intended for supply of a radiopaque liquid in a cavity of the uterus, and another - for inflating by means of a liquid entered into the cervical channel of the cuff, placed on the distal extremity of the catheter. The cuff is executed with possibility of acquisition of the cylindrical form after filling of its cavity with a liquid. And in inflated condition diametre of the cuff is not less than twice less than its length, and at a catheter introduction external diametre of the cuff coincides with the size of a two-channel tube. Thus the restrictor is established with possibility of free movement and bracing on a tube between the cuff and a catheter adapter. Application of the given device provides easy introduction and reliable bracing of a handpiece in the cervical channel, and also prevents leak of a contrast liquid from an examined organ. ^ EFFECT: easy introduction and reliable bracing of a handpiece in the cervical channel, and also prevention of leak of a contrast liquid from an examined organ. ^ 1 dwg |
