Abstract

The invention discloses a hysterosalpingography catheter, which comprises a catheter body, wherein the inner part of the catheter body includes an airbag channel and an injection channel; an airbag is arranged at the tail end of the airbag channel and an airbag channel plug is arranged at the front end of the airbag channel; the shortest distance between the tail end of the injection channel and the airbag, which is expanded, is 1cm; a hole is formed in the center of the tail end of the injection channel; an injection channel plug is arranged at the front end of the injection channel; and the hole is 1.1mm in diameter. According to the hysterosalpingography catheter disclosed by the invention, false positive performance of tubal occlusion on one side, which occurs when a fallopian tube, which may develop, fails to develop in the case that the tail end of the injection channel is too long, and subsequently, a uterine horn on one side is propped against by the hysterosalpingography catheter, is avoided. In addition, a thin guide wire can smooth enter a uterine cavity by virtue of the injection channel; and guided by the guide wire, the hysterosalpingography catheter can be smoothly inserted in the uterine cavity even in some cases with excessively forward-bent or backward-bent uteruses.

Description

A kind of hystero-salpingography tube

Technical field

The present invention relates to a kind of medical auxiliary equipment, be specially a kind of hystero-salpingography tube。

Background technology

The distal opening of the injection canal of hystero-salpingography tube commercial or general at present is arranged on the side of passage, for needing the case inserting angiography tube adopting thin seal wire to guide, and operation inconvenience；Additionally the end of angiography tube and air bag distance reach 2cm, it is easy to withstand the angular intrauterine of patient, especially for the patient that uterine cavity is less, occur that this oviductus lateralis does not develop, and cause that mistaken diagnosis is that this oviductus lateralis is inaccessible。

Summary of the invention

The technical problem to be solved is to provide a kind of hystero-salpingography tube, it is possible to avoids the end of angiography tube to withstand uterus one side corner sections, blocks the normal development of this oviductus lateralis, make visualisation more accurate。

For solving above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of hystero-salpingography tube, including pipeline, is divided into air bag passage and injection canal inside it, and the end of air bag passage is provided with air bag, and front end is provided with air bag passage plug；Minimum distance after the end of injection canal and airbag inflation is 1cm, and the center of its extreme ends has hole, and front end is provided with injection canal plug, and the diameter of hole is 1.1mm。

The cross section of described pipeline is circular, and caliber is 0.35cm, pipe range 37cm,

Maximum gauge after described airbag inflation is 1.5cm,

Described injection canal can be inserted into thin seal wire, guides angiography tube to enter cavity of uterus。

The front end of described air bag passage and injection canal and pipeline are y-branch structure,

Described pipeline and air bag are the parts adopting silicone rubber to make, and described air bag passage plug and injection canal plug are also adopted by silicone rubber and make。

Due to the fact that employing said structure design, minimum distance after the end of injection canal and airbag inflation is set to 1cm, when checking, even for the patient that uterine cavity is less, after airbag inflation closure cervix uteri mouth, the end of injection canal is without touching angular intrauterine, it is ensured that the contrast agent injected through injection canal can make cavity of uterus and bilateral salpingo development through pipe end hole。

The present invention has hole at the center of injection canal extreme ends, between uterus and cervix uteri, in severe, front bent or rear song changes, and the intrauterine patient of angiography tube not easily intron, it is possible to adopt thin seal wire to guide, then success rate can substantially increase。Avoid in traditional scheme and offer, at sidewall, the situation generation that the inconvenience of injection orifice guides。

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the invention will be further described:

Fig. 1 is the structural representation of the present invention。

Fig. 2 is the left view of Fig. 1。

Detailed description of the invention

As shown in Figure 1-2, the present invention includes pipeline 7, is divided into air bag passage 1 and injection canal 2 inside it, and the end of air bag passage 1 is provided with air bag 3, and front end is provided with air bag passage plug 4；Minimum distance after the end of injection canal 2 and air bag 3 expansion is 1cm, and the center of its extreme ends has hole 5, and front end is provided with injection canal plug 6, and the diameter of hole is 1.1mm。

The cross section of described pipeline 7 is circular, and caliber is 0.35cm, pipe range 37cm,

Diameter after the expansion of described air bag 3 is 1cm。

Described injection canal 2 can be inserted into thin seal wire, guides angiography tube to enter cavity of uterus。

The front end of described air bag passage 1 and injection canal 2 is y-branch structure with pipeline 7,

Described pipeline 7 and air bag 3 are the parts adopting silicone rubber to make, and described air bag passage plug 4 and injection canal plug 6 adopt silicone rubber to make。

During use, leading routine disinfection pudendum, vagina, paving aseptic hole towel, vaginal speculum exposes cervix uteri, iodine tincture, alcohol disinfecting cervix uteri and fornix portion；Cervical clamps stator labium anterius, and along the uterus orientation detection official jargon degree of depth；Inserting in uterine cavity by angiography tube pipeline 7 through cervical canal, inject gas 1-2ml through air bag passage, then fill in tight air bag passage plug 4, this air bag is possible to prevent contrast agent backflow cervix uteri and vagina；Under x-ray fluoroscopy, slowly inject iohexol injection through the hole 5 of injection canal 2, observe its situation entering cavity of uterus and bilateral salpingo and take the photograph sheet。

If patient uterine's neck and body of uterus are excessively front bent or bent afterwards, when angiography tube cannot be introduced into uterine cavity, first can insert thin seal wire through injection tube chamber, gentlier draw cervical clamps under fluoroscopy, under seal wire guides, by angiography tube intron uterine cavity, finally complete contrast examination。
