Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Please refer to fig. 1 and fig. 2 in combination, in which fig. 1 is an overall schematic view of a radiography tube not easy to fall off according to an embodiment of the present invention, and fig. 2 is an overall schematic view of another viewing angle of the radiography tube not easy to fall off according to an embodiment of the present invention. The utility model relates to a radiography tube that is difficult for droing, including radiography tube body 1 and the device 2 that opens and shuts.

One end of the radiography tube body 1 is closed, the other end of the radiography tube body 1 is opened, the opening and closing device 2 comprises a sleeve 21, a plurality of blades 22, a plurality of support rods 23 and an outer cladding 25, and the sleeve 21 can be axially movably sleeved outside the radiography tube body 1. The number of the plurality of blades 22 is equal to the number of the plurality of support rods 23, the blades 22 correspond to one another, one end of each blade 22 is a connecting end 221, the other end of each blade 22 is an open end 222, and the connecting ends 221 of the plurality of blades 22 are rotatably connected with the outer edge of the upper end of the sleeve 21 respectively. One end of each support bar 23 is rotatably connected to its corresponding blade 22, the other end of each support bar 23 is rotatably connected to the main body 1 of the contrast tube, and the connection portions of the plurality of support bars 23 and the main body 1 of the contrast tube are located on the same plane. The surrounding layer 25 of elastic material is hollow cylinder, and surrounding layer 25 wraps up in the periphery of radiography pipe body 1 and a plurality of blade 22, the upper end of surrounding layer 25 and the periphery fixed connection of radiography pipe body 1, the lower extreme of surrounding layer 25 and the periphery fixed connection of a plurality of blade 22 bottoms.

Preferably, the utility model discloses a contrast tube that is difficult for droing still includes retainer plate 24, and retainer plate 24 can reciprocate ground cover in the outside of contrast tube body 1, and retainer plate 24 is located the below of sleeve 21. Further, the fixing ring 24 is made of rubber.

In practical application, the position of the sleeve 21 may be moved to the bottom end, and at this time, the plurality of blades 22 and the plurality of support rods 23 are all tightly attached to the contrast tube body 1, and the whole body is represented as a cylinder. The closed end of the contrast tube body 1 is then inserted into the vagina and uterus of the patient in sequence until the plurality of blades 22 and the plurality of support rods 23 enter the uterus. Then the hand-held sleeve 21 is pushed upwards, when the hand-held sleeve is pushed to the maximum, the blades 22 are unfolded to the maximum angle, at the moment, the outer cladding 25 is unfolded to form two mutually buckled umbrella shapes, a ridge line is formed at the joint of the two umbrella shapes, the outer cladding can be supported at the uterine orifice, the outer cladding is not smooth like a balloon, the contrast tube cannot fall off, and the hand-held sleeve is suitable for patients with large uterine orifices. Then, the fixing ring 24 is moved up to abut against the lower end of the sleeve 21, and since the fixing ring 24 is made of rubber and has a certain pressure on the contrast tube body 1, the abutted sleeve 21 does not move down, and the plurality of blades 22 can maintain the opened shape. The outer cladding 25 wraps all the blades 22 and the supporting rods 23, so that the blades 22 can be prevented from hurting the inner wall of the vagina, and the comfort level is improved. In a preferred embodiment, the length of each blade 22 may be set to be 0.4 cm to 0.6 cm, so that the expanded outer diameter of the plurality of blades 22 is large enough to support the ostium of the uterus without the contrast tube falling off. The balloon is not required to be inflated by an external inflating device in the using process, the operation is convenient, and the fixing effect of the radiography tube is better.

Preferably, the outer side of the flared end 222 of each blade 22 is rounded. If the open ends 222 of the blades 22 are flat, the blades are not easy to enter the vagina and can scratch the inner wall of the vagina when entering the vagina, and the smooth cambered surfaces on the outer sides can enable the open ends 222 of the blades 22 to form a conical shape when being closed, so that the blades can easily enter the vagina and protect the inner wall of the vagina.

Preferably, the upper end of the contrast tube body 1 is provided with a medicine outlet 11, and the medicine outlet 11 is positioned outside the outer cladding 25. After the contrast tube is fixed in the uterus, contrast agent can be injected into the contrast tube body 1, and flows out of the medicine outlet hole 11 and enters the uterus for the required examination.

Preferably, the contrast tube body 1 is soft, and the sleeve 21, the plurality of blades 22 and the plurality of support rods 23 are all hard. The hard sleeve 21 is easier to push and insert into the uterus, and only if the blades 22 and the support rods 23 are designed to be hard, the blades and the support rods can be matched with each other to achieve the mechanical effect and achieve the purpose of supporting in the uterine orifice.

The present invention has been described in relation to the above embodiments, which are only examples for implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, all changes and modifications which do not depart from the spirit and scope of the present invention are deemed to fall within the scope of the present invention.
