As introduced in the background art, when the support is performed by the air bag in the prior art, the expansion of the air bag is not uniform, so that the different positions of the rectum or the vagina are not uniformly expanded, the support effect is affected, and the problems of local over-expansion and local no-support are easy to occur; in view of the above problems, the present disclosure provides a radiotherapy protector and protection device.
Example 1
In an exemplary embodiment of the present disclosure, a radiation therapy protector is provided, as shown in the figures.
Mainly include plug 1, gasbag 2 and grab handle 4, the plug is as main part bearing structure, plug one end is connected to the grab handle, make things convenient for the handheld grab handle of medical personnel to adjust the plug position, realize putting into or taking out the process at support position, the gasbag cover is established in the outside of plug, wraps up the plug, form the notes liquid chamber 8 that can fill into medium 9 between plug and gasbag, annotate liquid passageway 5 through the inside and inside plug of grab handle and to annotating liquid intracavity input or output medium, the realization is to the inflation or the extrusion shrinkage of filling into of gasbag.
Specifically, the core rod is of a cylindrical structure, the outer surface of the core rod is smooth, and the harder texture is used for supporting the air bag and the expanded air bag;
in this embodiment, the core rod may be made of resin plastic, and because different protection positions and different physical conditions of different people are different, the length and the diameter of the core rod may be configured as required, and generally configured as a long bar-shaped structure with an axial length greater than the diameter, so as to meet the requirement of covering the required support area.
Of course, it can be understood that, when the same kind of people carry out radiotherapy on different body parts, different positions also need to be protected, and therefore, core rods with proper lengths and diameters need to be selected according to requirements for different protection positions, so as to avoid the problems of insufficient protection capability or unstable placement due to overlong length.
Furthermore, one end of the core rod is connected with the grab handle, the liquid injection channel is also positioned inside the connecting position, and the other end of the core rod is a smooth hemispherical surface and serves as an embedded end, so that the core rod can be better embedded into a part to be protected.
On the other hand, the end part of the core rod is a smooth hemispherical surface, so that the surface mucosa in the body of a patient can be prevented from being damaged when one end of the core rod is placed into the human body, the rectal tissue, the rectal surface or the vaginal tissue and the vaginal surface mucosa of the patient are protected during radiotherapy, and the damage and bleeding of the protected part are reduced.
In addition, in order to utilize the muscle contraction of the human body to fix the position of the mandrel in the body, in the embodiment, one end of the mandrel connecting with the handle is provided with a contraction part 3, and the diameter of the contraction part is gradually reduced along the direction from the mandrel to the handle;
the core rod main part is the cylinder structure, and one end passes through the shrink portion and connects the grab handle, and the other end is slick and sly hemisphere face, annotates the liquid chamber and can drive the gasbag under the medium effect and radially expand or contract along the core rod.

the liquid injection channel is provided with at least two branch circuits 7 in the core rod, the liquid injection channel is communicated with the liquid injection cavity through the branch circuits, and the branch circuits are distributed at different positions in the core rod.
The liquid injection channel interface is arranged at the end part of the grab handle, the liquid injection channel is positioned inside the grab handle, the interference with the grab handle when the liquid injection pipe 6 is led out from the air bag is avoided, the structure inside the grab handle is fully utilized, and the sanitation during the medium injection and discharge is ensured.
Through many inside branches that set up of plug, the medium of annotating the liquid passageway input can be even pour into the plug in to make the plug can be more quick even sufficient inflation or release shrink, satisfy the demand to supporting the homogeneity among the radiotherapy treatment process.
It can be understood that, as shown in fig. 1, in this embodiment, the liquid injection channels are distributed inside the grip, the branches are located inside the core rod, and at least two branches may be symmetrically arranged inside the core rod with respect to the axis of the core rod, or may be arranged as required;
as shown in figure 1, 6 branches are arranged in total and distributed along the axial direction of the core rod, so that the problem that the filling liquid injection cavity is slow due to slow medium flowing caused by arrangement at one end of the core rod is solved, the medium can be quickly injected into the liquid injection cavity, and the air bag is quickly filled.
Of course, the number of the branches in the mandrel may also be increased or decreased according to the requirement, for example, increased to 7 or 8, or decreased to 4 or 5, and the like, and in addition, the arrangement manner of the branches may also be freely configured, for example, the branches extend to one end of the spherical surface of the mandrel, or the branches are arranged along the annular direction of the mandrel.
Further, before the air bag is used, gas is injected into a liquid injection cavity in the air bag through a grab handle tail end interface by using an injector, whether the air bag leaks gas or not is checked, and when the condition that no gas leaks is confirmed, the gas is sucked out, so that the air bag is deflated and clings to the core rod;
during the use, select the protector of suitable length and diameter according to the demand, use the condom cover outside the gasbag, put into the human body with the plug, after reaching the assigned position, to annotating the liquid intracavity and pour into the medium for gasbag outer wall supports the area protection position, thereby shelters from the irradiation position, reduces the volume that non-treatment position accepted the irradiation, reaches the purpose that reduces normal tissue damage.
It can be understood that the medium injected into the liquid injection cavity is selected according to the requirement, gas can be injected, liquid such as physiological saline can also be injected, and the medium can be selected according to the actual radiotherapy requirement.
