Safety-type salpingograph and contrast apparatus with location structureTechnical field
The present invention relates to medical instruments field, more particularly to a kind of safety-type salpingograph with location structure andContrast apparatus.
Background technology
The infertility incidence of disease is improved rapidly in recent years, and nineteen ninety-five World Health Organization's statistics shows that there is 6000- in the whole world80000000 couples of men and wives suffer from infertility, and China is currently without system statistics numeral.Infertility with cardiovascular disease, tumor diseaseThe three big diseases as influence human lives and health.The infertile major physiological factor of influence be uterus, fallopian tubal, ovary andSperm.Tubal infertility accounts for 20%-the 40% of infertility.Hysterosalpingography can check uterus and defeated ovum simultaneouslyPipe situation, uterine malformation, adhesion can be diagnosed simultaneously, and tubal occlusion, hydrops specify degree of mobility, be to check the defeated ovum in uterusPipe it is the most frequently used be also most standard diagnostic mode.
The main apparatus of hysterosalpingography inspection is foley's tube in current world wide.The application of foley's tube isMore than 30 years, there was production in domestic outer catheter manufacturer.Its operation principle is, by cervix dilating, foley's tube to be inserted into palaceIntracavitary, inflated blocks uterine neck internal orifice, and contrast agent is injected by conduit collar extension, and contrast agent flows into uterine cavity by fallopian tubal, fromAnd judge fallopian tubal situation.Its shortcoming is obvious：
1) sacculus is full of uterus, has to uterus shape and problem and blocks to a certain degree, it is impossible to reacts real problems comprehensively,There is certain mistaken diagnosis probability, be also easy to produce conflict between doctors and patients；
2) conduit head end is occasionally butted on palace angle, blocks fallopian tubal opening phenomenon, causes tubal occlusion illusion；
3) conduit enter uterine cavity to carry out expand palace operation, therefore to uterine neck and endometrium have destruction and the operating time it is long,Not only increase patient suffering also reduces the operating efficiency of medical personnel；
4) the excessive risk bad phenomenons such as sacculus ruptures, sacculus can not bounce back after filling up can occur in uterine cavity for foley's tube,Significantly increase Salpingography risk；
5) foley's tube is after uterine cavity is inserted, and the conduit obscission that happens occasionally is, it is necessary to which secondary intubation, adds patient'sPain；
6) due to needing to enter uteroventral operation, although checked in dept. of radiology, this inspection is also generally all by womanSection doctor operates, and is then diagnosed by radiologist, operating process is more cumbersome.

Radiography device
The invention provides a kind of safety-type salpingograph with location structure, the radiography device includes：Bullet,Load radiography bar, Anti-backflow structure and optional pedestal, the tip of bullet are located at the distal end of the radiography device, and the coneThe front end of body is provided with radiography fluid outlet, and the side of bullet is sunken inside cambered surface, and load radiography bar, which is provided with, supplies contrast solution streamLogical bar internal channel so that contrast solution flows through the bullet from the bar internal channel and flowed out from the radiography fluid outlet.
Radiography device is additionally provided with the slidingtype location structure relative to the load radiography bar, and the location structure includes activityState and lock-out state：Under the active state, the location structure can be along axial direction (or the length side of the load radiography barTo) slide；Under the lock-out state, the location structure is fixed relative to the load radiography bar.Described location structureIncluding locator and positioning lock, described positioning lock is arranged on the locator, and adjusting the positioning lock can control to holdThe activity of power radiography bar or locking, described locator are provided with card-bit part.
The Anti-backflow structure of the present invention includes but is not limited to piston switch, check valve, anti-return valve, and Anti-backflow structure canTo be connected with load radiography bar, or it is connected with pedestal, and is removable lining or integral with pedestal.
Positioning lock is adjusted when using so that load radiography bar is active, and propulsion load radiography bar causes bullet to enterEnter vagina and be placed in cervical orifice, regulation positioning lock causes load radiography bar to be in the lock state, from the transfusion of Anti-backflow structureEnd input contrast fluid, the bar internal channel through load radiography bar causes contrast solution to flow through the bullet simultaneously from the bar internal channelFrom radiography fluid outlet outflow.
Contrast apparatus
The invention provides a kind of safety-type fallopian tube radiography device with location structure, the device include fixator andRadiography device described above.
The fixator includes base and support bar, and the support bar sets U-shaped groove, and the U-shaped groove internal diameter is less thanWith the load radiography bar external diameter.
When the load radiography bar of radiography device is in the lock state, load radiography bar is inserted into U-shaped groove, and willThe card-bit part of location structure blocks the support bar, so as to realize that radiography device is fixed on fixator.
Main advantages of the present invention include：
(a) position after the positioning of radiography device opening of the cervix is realized in locator, positioning lock, fixator and load radiography bar synergyPut fixation, it is to avoid the occurrence of contrast agent in patient's movement, contrast solution injection pressurization leaks outside.
(b) pedestal, Anti-backflow structure realize that the pressure after contrast solution injection is kept, and have both improved radiography definition, and completeAvoid the generation that patient directly contacts X-ray entirely.
(c) both being fitted according to the outer radian of bullet that the opening of the cervix sized data of clinical statisticses is designed with opening of the cervix, it is close to realizeEnvelope turn avoid bullet to be influenceed to check precision and the generation of degree of impairment is caused to patient into uterine cavity.
(d) the radiography device changes the radiography mode of inflated, accomplishes no dead angle completely, it is to avoid sacculus explosion, sacculusThe potential risks such as compressing, de- pipe, are reduced in radiography because sacculus is covered, deformation causes false positive.
(e) the radiography device is simple in construction, can quickly grasp, the need for can meeting 95% crowd.
