Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of disposable selective salpingography water service pipe.
Background technology
Fallopian tube is conveying ovum, facilitates the fertility passage of ovum and sperm combination, and salpingemphraxis is the one of the main reasons of female acyesis, and Infertility caused by fallopian tube obstruction accounts for 67% in China's female acyesis according to statistics.Tubal patency inspection method is many, and comprise imaging examination, hydrotubation and coaxial falloposcopy laparoscopy, imaging examination comprises hysterosalpingography, Hysterosalpingocontrast sonography etc.Hydrotubation is simple and easy to do, but there is larger blindness and inaccuracy, at present as a kind of primary dcreening operation means.Coaxial falloposcopy inspection can observe Fallopian tube mucosa situation intuitively, is more used for assessment operation prognosis and adjustment therapeutic scheme.The lower hydrotubation inspection of peritoneoscope direct-view is considered to the most reliable inspection method at present, but has wound property and expensive due to Laparoscopic, is more prone at present as treatment means.Hysterosalpingography is the main inspection method of oviduct obstructive sterility, but due to this inspection method be utilize the contrast agent of doses to fill cavity of uterus after, persistent pressure perfusion makes contrast agent backflow to fallopian tube from uterine cavity to develop, this method exists in pressurized liquid injection process, most patients's comfort level is bad, even produce severe pain, uterus and fallopian tube spasm causes that salpingemphraxis false positive results occurs and occurs, easily cause interstitial adverse current under uterine cavity high pressure conditions simultaneously, damage endometrium even occurs or increases the weight of to infect, thus cause salpingemphraxis or increase the weight of degree of congestion.The Hysterosalpingocontrast sonography of development in recent years is also according to the full uterine cavity radiography of pressurization, also there is above-mentioned shortcoming.
Selective salpingography/logical liquid directly carries out Interventiond fallopian tube radiography, pressurize without the need to uterine cavity, can more accurately reflect obstruction of fallopian tube and Tubal Function of Sterility, objective evaluation is carried out to Tubal recanalization, pliability, tube chamber mucosa, umbrella end situation, pelvic cavity disperse etc.Selective salpingography/logical liquid, not only diagnosable but also can treat, greatly compensate for the deficiency of conventional hysterosalpingography.Existing apparatus has conventional hysterography water service pipe and gets involved dredging conduit, the latex balloon pipe of conventional radiography aims at full uterine cavity and uses, injection of medicine can only make fallopian tube develop by uterine cavity-fallopian tube approach, sacculus only card lifting presses the effect of cervix uteri internal orifice, can not carry out selective salpingography.Carry out selective salpingography/logical liquid at present often to select intervention dredging conduit, have the following disadvantages: 1. getting involved dredging conduit can not carry out conventional hysterography; 2. interposing catheter is comparatively hard, need under seal wire guides intubate, tube head easy damaged endometrium; 3. get involved dredging conduit conductor housing angle of bend to fix, angle of bend can not be changed according to cornua uteri traveling situation; 4. get involved dredging conduit to be transformed by blood vessel interposing catheter, price is more expensive.Therefore there is no special selective salpingography/logical fluid catheter at present, the objective one that need design can be gone conventional radiography and can be manageed it again selective salpingography, and just simple to operate, low-cost equipment special.
From the above, be necessary to be further improved inventory
Summary of the invention
For above problem, it is simple, reasonable that this utility model provides a kind of structural design, cost is low, operation uses simple, convenient, can conventional hysterography and selective salpingography be carried out, compensate for the disposable selective salpingography water service pipe of conventional hysterography diagnosis obstruction of fallopian tube deficiency.
This utility model is achieved through the following technical solutions:
Above-mentioned disposable selective salpingography water service pipe, comprises pipe shaft and is located at sacculus, medicine-injecting connector and the sacculus gas injection joint on described pipe shaft; Described pipe shaft is made up of tube core and the rubber layer being coated on described tube core outer wall; Described pipe shaft comprises balloon conduit and injection pipeline; Described medicine-injecting connector is connected to the medicine-injecting end of described injection pipeline, and described sacculus gas injection joint is connected to the gas injection end of described balloon conduit; The tube head end of described balloon conduit radially offers three gas outlets, hole; The tube head end of described injection pipeline is taper head end and offers stomidium vertically; Described sacculus is near the tube head end of described pipe shaft, and it is formed after departing from described tube core outer wall by the rubber layer of described pipe shaft; The wall thickness of the relative both sides of described sacculus is different, the side that the cyst wall that described three gas outlets, hole are positioned at described sacculus is thicker.
