Abstract
The utility model relates to a neutron after-loading treatment machine, which comprises a main unit, a therapeutic bed and a shield mask, wherein the shield mask is connected with the therapeutic bed in an opposite inclusion manner. The shield mask connected with the therapeutic bed in the opposite inclusion manner can surround a patient to shield a radioactive source, so that the other places in the therapeutic room is kept in a relatively safe state with lower radiation leak level. Accordingly, the medical staff entering the therapeutic room in emergency is exposed to relatively low radiation dose. Meanwhile, the shield mask can properly alleviate the radiation protection pressure of machine room of the therapeutic room, thereby reducing the shielding thickness and lowering the construction cost.
Description
Technical field
This utility model relates to the neutron afterloader.
Background technology
Existing neutron afterloader, comprise main frame and therapeutic bed, main frame comprises driving mechanism, source rope, stem pipe, cask flask and neutron source, the source end of restricting is connected with driving mechanism, the other end is fixedlyed connected with neutron source, driving mechanism drives neutron source operation in the stem pipe by the drive source rope, and by apparatus for wave-energy source neutron source is sent into and to be carried out radiotherapy in the body cavities, when carrying out radiotherapy, owing to have neutron irradiation in the therapeutic room, therefore, medical personnel in case of emergency directly enter therapeutic room, can be subjected to certain radiation damage.
The utility model content
This utility model provides a kind of neutron afterloader, carry out in the process in treatment to solve existing neutron afterloader, medical personnel in case of emergency enter the bigger problem of the suffered radiation damage of therapeutic room, simultaneously, increase the radiation protection pressure that radome can also suitably alleviate therapeutic room's machine room, reduce shielding thickness, reduce construction cost.
In order to solve above technical problem, the technical scheme that this utility model is taked is:
A kind of neutron afterloader, comprise main frame and therapeutic bed, main frame comprises driving mechanism, source rope, stem pipe, cask flask and neutron source, the source end of restricting is connected with driving mechanism, the other end is fixedlyed connected with neutron source, and driving mechanism drives neutron source operation in the stem pipe by the drive source rope, it is characterized in that, also comprise radome, the relative enclose with therapeutic bed of described radome connects.
Described radome is that transparent material is made.
Described radome and therapeutic bed flexibly connect.
Described therapeutic bed is positioned at radome, and radome is provided with shield door and air-vent.
After having adopted technique scheme, owing to increased radome, the relative enclose with therapeutic bed of radome connects.Therefore, the conductively-closed cover is enclosed in the radome during patient, other scope in the therapeutic room is owing to the shielding of radioactive source conductively-closed cover is in the lower comparatively safe state of compromising emanation level, therefore, it is less relatively that medical personnel in case of emergency enter the suffered radiation dose of therapeutic room, simultaneously, increases the radiation protection pressure that radome can also suitably alleviate therapeutic room's machine room, reduce shielding thickness, reduce construction cost.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of neutron afterloader, comprise main frame 1, therapeutic bed 2 and radome 3, main frame comprises driving mechanism, source rope, stem pipe, cask flask and neutron source, the source end of restricting is connected with driving mechanism, and the other end is fixedlyed connected with neutron source, and driving mechanism drives neutron source by the drive source rope and moves in the stem pipe, radome 3 connects with therapeutic bed 2 relative enclose, and radome 3 is made for transparent material.
Claims (4)
1, a kind of neutron afterloader, comprise main frame and therapeutic bed, main frame comprises driving mechanism, source rope, stem pipe, cask flask and neutron source, the source end of restricting is connected with driving mechanism, the other end is fixedlyed connected with neutron source, and driving mechanism drives neutron source operation in the stem pipe by the drive source rope, it is characterized in that, also comprise radome, the relative enclose with therapeutic bed of described radome connects.
2, neutron afterloader as claimed in claim 1 is characterized in that, described radome is that transparent material is made.
