Description
Technical Field
The utility model relates to a medical apparatus, in particular to a colorectal radiography tube.
Background
In pediatric clinical work, colonography is an important diagnostic method for infants suffering from megacolon, ileus, etc. For infant colorectal radiography, a contrast tube is needed to be used for injecting contrast agent into colorectal, in the prior art, a colon radiography tube specially designed for infants is not available, most hospitals use a catheter for replacement, the catheter is not provided with a backflow prevention device, and when the pressure in the colorectal is increased, the contrast agent leaks and overflows from an injection pipeline, so that the radiography effect is affected, cross infection is possible, and the medical efficiency is affected.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an anti-leakage infant colorectal radiography tube which is stable and reliable in operation and can provide necessary guarantee for colorectal radiography.
In order to solve the technical problems, the anti-leakage infant colorectal radiography tube comprises a rubber dual-cavity tube, and further comprises a first one-way valve and a second one-way valve which are matched with the dual-cavity tube; the main channel of the double-cavity tube is provided with a contrast agent injection pipeline, and the side tube wall of the double-cavity tube is provided with an inflation pipeline; the front end of the double-cavity tube is provided with a cone head with a closed top end, an annular cavity is formed on the double-cavity tube behind the cone head in an integrally formed coating manner, and the annular cavity is mutually isolated from the contrast agent injection pipeline; a contrast agent through hole is formed in the side wall of the double-cavity tube between the conical head and the annular cavity; the front end of the contrast agent injection pipeline is communicated with the contrast agent through hole, and the rear end of the contrast agent injection pipeline is communicated with the first one-way valve; the front end of the air charging pipeline is communicated with the annular cavity, and the rear end of the air charging pipeline is communicated with the second one-way valve.
In the technical scheme, the annular cavity can be inflated to form the air bag after entering the body, so that the fixed pipeline is not easy to deviate from the rectum cavity, the air bag pressure can be ensured by the one-way valve at the rear end of the inflation pipeline, and the pressure leakage of the contrast agent can be prevented by the one-way valve at the rear end of the contrast agent injection pipeline, so that the colorectal radiography process is ensured to be successfully completed.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a cross-sectional view of fig. 1 taken along line A-A.
Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings.
As can be seen from fig. 1 and 2, the anti-leakage infant colorectal radiography tube comprises a rubber dual-cavity tube 1, and further comprises a first one-way valve 2 and a second one-way valve 3 which are matched with the dual-cavity tube; the main channel of the double-cavity tube is provided with a contrast agent injection pipeline 10, and the side tube wall of the double-cavity tube is provided with an inflation pipeline 11; the front end of the double-cavity tube is provided with a cone head 12 with a closed top end, the cone head 12 and the double-cavity tube 1 are in smooth transition, an annular cavity 13 is formed on the double-cavity tube 1 behind the cone head 12 in an integrally formed coating manner, and the annular cavity 13 is mutually isolated from the contrast agent injection pipeline 10; a contrast agent through hole 14 is arranged on the side wall of the double-cavity tube between the conical head 12 and the annular cavity 13; the front end of the contrast agent injection pipeline 10 is communicated with the contrast agent through hole 14, and the rear end is communicated with the first one-way valve 2; the front end of the air charging pipeline 11 is communicated with the annular cavity 13, and the rear end of the air charging pipeline is communicated with the second one-way valve 3.
The double-cavity tube is a rubber tube body, can be divided into a number 12 (diameter 4 mm) and a number 16 (diameter 5.3 mm) according to different tube body diameters, and is characterized in that the rear end (one end of the one-way valve) is a liquid inlet end, the front end is a liquid outlet end, the one-way valve of the liquid inlet end is connected with the injector in a matched manner, and the injector can be used for directly injecting contrast agent after being connected.
The inflation pipeline 11 is arranged in the pipe wall of the double-cavity pipe 1, the contrast agent injection pipeline 10 is not communicated with the inflation pipeline 11, the front end of the inflation pipeline 11 is communicated with the annular cavity 13, and the annular cavity can be expanded into an air bag under the inflation condition so that the fixing pipeline is not easy to deviate from the rectum cavity.
The using process comprises the following steps: A. the double-cavity tube 1 is extruded, the air is exhausted from the contrast agent through hole 14, and the closed pipeline among the annular cavity 13, the air inflation pipeline 11 and the second one-way valve 3 leaves the factory in a low-pressure state, so that the outer diameter of the annular cavity 13 is deformed and reduced.
B. The cone head 12 is inserted into the rectum until the annular cavity 13 is completely inside the body.
C. Injecting gas from the second one-way valve 3 by using an injector to expand the annular cavity 13 into an air sac so that the fixed pipeline is not easy to directly escape from the rectum cavity; contrast is injected from the first check valve 2 using a syringe through the contrast through-hole 14 into the body. In this step, physiological saline may be injected into the annular chamber 13 to expand the annular chamber.
D. After the inspection is completed, the connecting pipeline of the second one-way valve 3 is firstly damaged, so that the pressure of the annular cavity 13 is relieved, then the connecting pipeline of the first one-way valve 2 is damaged, so that the pressure of the main pipeline is relieved, and then the whole pipeline is removed.
The present utility model is not limited to the above-described embodiments, and various modifications and variations can be made by those skilled in the art in light of the present utility model without departing from the spirit and the essence of the utility model, but still fall within the scope of the utility model.
