Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of safety-type Salpingography with location structure
Device and contrast apparatus.
Background technology
Infertility incidence improves rapidly in recent years, and nineteen ninety-five World Health Organization's statistics shows that there is 6000- in the whole world
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 of influence 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 operation principle is that foley's tube is placed in palace by cervix dilating
Intracavitary, inflated block uterine neck internal orifice, and contrast agent is injected by conduit collar extension, and contrast agent flows into uterine cavity by fallopian tubal, from
And judge fallopian tubal situation.Its shortcomings that is apparent：
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, blocks fallopian tubal opening phenomenon, leads to tubal occlusion illusion；
