80000000 couples of men and wives suffer from infertility, and China is currently without system statistics number.Infertility with cardiovascular disease, tumor disease
As the three big diseases for influencing human lives and health.Influence infertile major physiological factor be uterus, fallopian tubal, ovary and
Sperm.Tubal infertility accounts for 20%-the 40% of infertility.Hysterosalpingography can check uterus and defeated ovum simultaneously
Pipe situation can diagnose uterine malformation, adhesion simultaneously, and tubal occlusion, hydrops specify degree of mobility, be to check the defeated ovum in uterus
The diagnostic mode of the most frequently used and most standard of pipe.
The main instrument of hysterosalpingography inspection is foley's tube in world wide at present.The application of foley's tube is
More than 30 years, there was production in domestic outer catheter manufacturer.Its working principle is that foley's tube is placed in palace by cervix dilating
Intracavitary, inflated blocks uterine neck internal orifice, injects contrast solution by conduit collar extension, and contrast solution flows into uterine cavity by fallopian tubal, from
And judge fallopian tubal situation.
But during clinical use, existing foley's tube has the shortcomings that following obvious:
1) sacculus is full of uterus, has to uterus shape and problem and blocks to a certain degree, cannot react real problems comprehensively,
There is certain mistaken diagnosis probability, is also easy to produce conflict between doctors and patients；
2) conduit head end is occasionally butted on palace angle, blocking fallopian tubal opening phenomenon, leads to tubal occlusion illusion；
3) the high risks bad phenomenons such as sacculus rupture can occur in uterine cavity for foley's tube, sacculus cannot bounce back after filling up,
Significantly increase Salpingography risk；
4) in the bolus infusion processes of contrast solution, pressure and flow velocity are uncontrolled, excessive pressure and flow velocity to fallopian tubal villus,
Endometrium has irreversible damage.
