Technical Field
The utility model relates to the field of medical instruments, in particular to a hystero-salpingography catheter.
Background
Hysterosalpingography is a common examination method for diagnosing uterine malformation and tubal obstruction, and in the examination process of female infertility patients, doctors need to put a contrast catheter into a cervical canal cavity and fix the contrast catheter under the assistance of a vaginal speculum to ensure that a contrast agent fills the uterine cavity and the fallopian tube, so as to prevent the catheter from falling off and the contrast agent from reversely flowing into the vagina to cause contrast failure and influence on image quality. At present, a double-cavity air bag catheter is commonly used for clinical radiography, after the head end of the catheter is placed into a cervical canal, an air bag at the neck of the catheter expands, the cervical canal is inflated at high pressure, and the cervical canal is blocked, but due to the individual difference of pain sensitivity, local inflammation, pressure injury and the like, a part of patients have strong discomfort such as pain and the like in the operation of placing the catheter, so that the problems of low acceptance of a hystero-salpingography patient, uncoordinated operation process and the like are caused, even the problems of low quality of radiography images and inharmonious relationship of doctors and patients are caused, the examination and development are limited to a certain extent, and the medical risk is increased.
Disclosure of Invention
In order to solve the problems, the utility model provides a hystero-salpingography catheter, which aims to provide a new technical scheme, improve the air bag fixing structure of the angiography catheter, solve the technical problems of discomfort such as pain and the like caused by the expansion and high-pressure filling of the air bag at the neck part of the catheter and the blockage of the cervical lumen after the head end of the catheter is placed into a cervical canal, improve the acceptance of a patient on hystero-salpingography examination and reduce medical risks.
In order to achieve the purpose, the utility model provides the technical scheme that: a hysterosalpingography catheter is characterized in that an outer catheter body is a hollow slender cylindrical sealing structure made of hard plastics, the top end of the outer catheter body is connected with a tapered and sharp outer catheter head, and the tail end of the outer catheter body is provided with a compact cylindrical outer catheter tail.
A first rubber plug is installed at the center of the tail of the outer catheter.
And a second rubber plug is arranged on the side wall of the outer catheter body adjacent to the tail of the outer catheter.
An air bag is arranged around the outer catheter body adjacent to the outer catheter head, one third of the side of the air bag head is an umbrella part, and two thirds of the side of the air bag tail is a ball part.
The side wall of the outer catheter body is provided with a round air hole which is communicated with the balloon part.
The inner catheter body is arranged in the cavity of the outer catheter body and is of a hollow long and thin cylindrical structure made of hard plastic, the head end of the inner catheter body is fused with the top end of the outer catheter head and is provided with a liquid hole, and the tail end of the inner catheter body is sealed by a first rubber plug.
According to the uterotubal angiography catheter provided by the utility model, the second rubber plug is arranged on the side wall of the outer catheter body adjacent to the tail of the outer catheter, so that the outer catheter cavity can be sealed, and the gas filled by the second rubber plug is utilized to enter the outer catheter cavity or be pumped out of the outer catheter cavity by the syringe; install the gasbag around the outer catheter body of neighbouring outer catheter head, it communicates with each other with the gasbag bulb to have seted up circular shape gas pocket on the outer catheter body lateral wall, gasbag first side third is umbrella portion, gasbag tail side two-thirds is the bulb, attach to in outer catheter when not sufficient and make things convenient for the intubate operation around, the gasbag expands when being sufficient gaseous, umbrella portion top and the outer mouthful form adaptation of cervical and shutoff cervical outer mouthful, be favorable to stopping the contrast medium palirrhea, the bulb then fills the vaginal cavity and is favorable to preventing that the pipe from dropping down, whole sacculus design is favorable to avoiding the gasbag to expand in the cervical and produce uncomfortable feelings such as pain. The tapered and sharp outer catheter head is favorable for placing the outer catheter head into a cervical canal during catheter intubation operation, and the compact cylindrical outer catheter tail is favorable for stable sealing of the whole catheter. The inner catheter body is arranged in the cavity of the outer catheter body, so that the liquid channel and the gas channel are completely separated, the head end of the inner catheter is fused with the top end of the outer catheter head, the liquid hole is formed, the tail end of the inner catheter is sealed by the first rubber plug, and the syringe is favorable for puncturing the first rubber plug and pushing the contrast agent into the uterine cavity through the liquid hole.
