CN208212285U - Disposable uterine cavity leads to liquid angiography tube - Google Patents

Abstract

The utility model relates to a disposable uterine cavity fluid-passing radiography tube, which comprises a radiography tube body. The center of the radiography tube body is a drug injection cavity. The first air bag and the second air bag are arranged at intervals in sequence, and an introduction rod is installed in the injection chamber. . The utility model can inject gas into the first air bag and the second air bag at the same time when inspecting a patient with cervical relaxation, so that the first air bag and the second air bag are closely attached to the inner wall of the cervix and are not easy to slide. The contact area between the introduction rod and the imaging tube body can be increased, so that the pressure on the front end of the imaging tube body becomes smaller, thereby reducing the risk of the front end of the imaging tube body being smashed. The introduction rod can be avoided from excessively protruding into the main body of the contrast tube and destroying the main body of the contrast tube.

Description

Disposable hysterography catheter

technical field

The utility model relates to the field of medical instruments, in particular to a disposable uterine cavity fluid-passing radiography tube.

Background technique

During gynecological examinations or treatment of gynecological diseases, it is often necessary to use a hysterography tube to infuse a contrast agent into the uterus. When using it, the hysterography tube is inserted into the uterus. Then use an inflator to inflate the balloon to seal the cervix so as to seal the uterine cavity, and then inject contrast agent into the uterine cavity through the injection tube. At present, the hysterography tubes used are all made of medical rubber, and the material is relatively soft. The hysterography tube is easy to bend, which makes it time-consuming and laborious to place. Some of them are guided by a guide wire, which is easy to grasp the length of the guide wire and is easy to damage. Hysterography tube, and for patients with a loose cervix, the installation of the hysterography tube is poor and easy to slip, which affects the accuracy of the examination results.

Utility model content

The purpose of the utility model is to provide a disposable hysterograph tube to solve the problems in the prior art that the hysterograph tube is difficult to place, easy to slip, and easy to cause damage to the hysterograph tube.

In order to achieve the above object, the technical scheme that the utility model takes is:

A disposable uterine cavity liquid contrast tube, comprising a contrast tube body, the center of the contrast tube body is a medicine injection cavity, a liquid outlet hole is provided on the front side of the contrast tube body, and the liquid outlet hole communicates with the drug injection cavity, and the contrast tube body The body is provided with a first air bag and a second air bag at intervals in sequence behind the liquid outlet hole, and a first inflatable tube and a second inflatable tube extending along the length direction of the contrast tube body are provided between the outer wall of the contrast tube body and the inner wall of the drug injection cavity. , the side wall of the rear part of the imaging tube body is provided with a first connecting pipe and a second connecting pipe, the front end of the first inflatable pipe communicates with the first airbag, the rear end of the first inflatable pipe communicates with the first connecting pipe, and the upper end of the first connecting pipe The first air intake control valve is installed, the first connecting pipe is connected with the first exhaust pipe on the front side of the first air intake control valve, the first exhaust pipe is provided with the first exhaust valve, and the front end of the second inflation pipe is It communicates with the second airbag, the rear end of the second inflation pipe communicates with the second connecting pipe, the second connecting pipe is installed with the second intake control valve, and the second connecting pipe is connected with the first Two exhaust pipes, the second exhaust pipe is provided with a second exhaust valve, the ends of the first connecting pipe and the second connecting pipe are connected with inflatable balls, an introduction rod is installed in the injection cavity, and the front end of the introduction rod is set There is a spherical end, and the rear end of the introduction rod is provided with a baffle for being stuck on the outside of the injection chamber port.

The rear end of the introduction rod is provided with a handle behind the baffle.

The inner wall of the front end of the injection chamber is provided with an arc-shaped groove matching with the spherical end.

In the utility model, a first air bag and a second air bag are sequentially arranged at intervals behind the liquid outlet on the imaging tube body. For patients with loose cervix, gas can be injected into the first air bag and the second air bag at the same time, so that the first air bag and the second air bag The second airbag fits tightly with the inner wall of the cervix and is not easy to slide, so that the imaging result is reliable. A spherical end is provided at the front end of the introduction rod, which can increase the contact area between the introduction rod and the imaging tube body, so that the front end of the imaging tube body is affected. The pressure becomes smaller, thereby reducing the risk of the front end of the contrast tube body being smashed. At the same time, there is a baffle at the rear end of the introduction rod. In this way, the guide rod can be prevented from being excessively extended into the contrast tube body and destroying the contrast tube body, so as to ensure the accuracy of the imaging detection of the contrast tube body.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a disposable uterine cavity liquid contrast tube includes a contrast tube body 1, the center of the contrast tube body is a drug injection cavity 2, and a liquid outlet hole 3 is provided on the front side of the contrast tube body. It communicates with the drug injection cavity 2, and the imaging tube body is provided with a first air bag 4 and a second air bag 5 at intervals in sequence behind the liquid outlet, and a gap along the length direction of the imaging tube body is provided between the outer wall of the imaging tube body and the inner wall of the drug injection cavity. Extended first inflation pipeline 6 and second inflation pipeline 7, first connecting pipe 8 and second connecting pipe 9 are arranged on the side wall of the rear part of the contrast tube body, the front end of the first inflation pipeline 6 communicates with the first air bag 4, the second The rear end of an inflatable pipeline 6 communicates with the first connecting pipe 8, the first connecting pipe 8 is equipped with a first air intake control valve 10, and the first connecting pipe is connected with a first row of Air pipe 11, the first exhaust pipe 11 is provided with a first exhaust valve 12, the front end of the second inflation pipeline 7 communicates with the second air bag 5, the rear end of the second inflation pipeline 7 communicates with the second connecting pipe 9, and the second inflation pipeline 7 communicates with the second connecting pipe 9.
