Description

Uterus oviduct radiography and treatment infusion apparatus

Technical Field

The utility model relates to a medical appliance, in particular to a uterus oviduct radiography and treatment infusion apparatus used for the examination and the evaluation of infertility and the treatment of uterus oviduct.

Background

At present, uterine-oviduct radiography (HSG) and liquid-flowing methods are mostly adopted for diagnosing and treating the tubal infertility, and the diagnosis and treatment method generally adopts a small catheter to input liquid medicine or gas into the uterine cavity and the fallopian tube. In order to fix the tip of the small catheter in the cervical canal and prevent the injected liquid medicine or gas from overflowing from the cervical canal, doctors often use a small or rod-shaped sheath contrast medium-passing device with a balloon to block the cervical canal. When the small catheter enters the uterine cavity, the pain and infection of the patient can be increased. The filled balloon can passively enlarge the uterine cavity, so that the endometrium of a patient is torn to cause pain, and the damage of the endometrium can cause a large amount of bleeding. Sometimes, the intrauterine filled balloon can cause the change of the intrauterine volume, thereby causing filling defect displayed on an artificial image, often covering the uterine cavity lesion, even causing false positive caused by non-development of one side of the fallopian tube, and obviously influencing the diagnosis of the HSG on the uterine cavity and the fallopian tube lesion. As for a patient pregnant many times, the rod-shaped sheath tube liquid passing radiography instrument is difficult to block liquid medicine in a uterine cavity because the structure of a pelvic floor is relatively loose and the uterus bends forwards or backwards, and the cervical clamp is required to be used for auxiliary operation, thereby often causing damage to the cervix or the uterus. The rod-shaped contrast apparatus for introducing liquid into the sheath canal affects the effect of blocking the external opening of the cervix due to the different shapes of the external opening of the cervix of each patient, and thus, the liquid medicine or gas overflows and cannot bring the expected effect. And the conventional medicine-taking anti-inflammatory treatment is carried out after the uterus angiography transfusion to avoid infection after operation, and in the prior art, the other three-way transfusion channel is used for dropping or injecting for anti-inflammatory treatment while the uterus angiography transfusion is carried out, so that the defect that the anti-inflammatory treatment cannot be continuously treated together with or successively after the uterus angiography transfusion in the prior art is overcome.

The uterus oviduct radiography and treatment infusion apparatus is characterized in that an outer catheter is made of high polymer materials, a small catheter is made of high polymer materials, and one end of the outer catheter inserted into a cervical orifice is conical with a fine opening crackThe small catheter is easier to insert into the cervical canal, the injury of the cervical canal and the uterus is not easy to cause, the small catheter is convenient to enter for partial cervical canal stenosis and partial adhered cervical canal without the help of uterus dilatation measures, the elastic body is released after entering the proper position of the cervical canal,to be provided withThe small catheter is fixed in the cervical canal, so that the small catheter is not easy to slide out, liquid or gas entering the uterine cavity does not overflow due to good sealing property of the elastomer, the release tension of the elastomer is proper, the expansion of the cervical canal is not obvious, a patient does not feel pain, meanwhile, the uterus of the patient is slightly injured after radiography or liquid-through ventilation, bleeding is less, and pain and human pain caused by instrument operation and human pain are not generated

Physical discomfort.

The small catheter or the liquid through pipe is made of high polymer materials with proper hardness, the front end of the small catheter or the liquid through pipe is in a cone shape with a crack, the cone body is favorable for guiding the inner catheter to enter the external opening of the cervix, the front end of the small catheter or the liquid through pipe can be properly expanded along with the advance of the elastic body, and the elastic body can smoothly extend out of the outer catheter.

The utility model is suitable for the anti-inflammatory treatment of the conventional transfusion while carrying out operations such as hysterosalpingography, hysterosalpingemphraxis or ventilation and the like. Compared with the prior art, the method has the following advantages:

1. the utility model adopts a tiny small catheter, the PVC polymer front end material has certain supporting force and is easy to pass through a narrow and lightly adhered cervical canal, thereby reducing the damage entering the cervical canal and uterus and leading a patient not to generate pain;

2. the elastic body is released at a proper position when entering the cervical canal, so that a gap between the small catheter and the cervical canal can be blocked, the small catheter is fixed to prevent the small catheter from sliding out of the cervical canal, and liquid or gas in the uterine cavity can not overflow;

3. the pipe joint at the other end of the small conduit is connected with a one-way valve which can effectively prevent liquid from flowing back and forth from the small conduit;

4. the cervical dilator is simple to manufacture and operate, is easy to fix in a cervical canal, does not need to pull the cervix, has small damage to the cervical canal and little bleeding, and does not cause uterine pain and personal discomfort;

5. the front end of the outer catheter is conical with an opening crack, so that the conical body is favorable for guiding the inner catheter to enter the cervical orifice, and the elastic body can smoothly pass through the front end of the outer catheter;

6. the conventional anti-inflammatory treatment is mainly carried out after hysterography and liquid or ventilation, so that intermediate links are reduced, the treatment time is shortened, and the treatment effect is improved.
