Technical Field

[0001] The utility model relates to the medical field, in particular to a source pouring tank. Background Art

[0002] Gamma Knife is the main treatment method of stereotactic radiosurgery. It is based on the principle of stereoscopic geometric orientation. It selectively identifies normal tissue or diseased tissue in the brain as the target, and uses gamma rays produced by cobalt-60 for a one-time large-dose focused irradiation to produce focal necrosis or functional changes to achieve the purpose of treating the disease.

[0003] Cobalt-60 radiation sources can treat cancer, but can also have impacts on humans and the surrounding environment. Radiation protection must be ensured when installing radiation sources into equipment.

[0004] Therefore, it is necessary to provide a kind of inverted source tank to install the radioactive source to the gamma knife equipment. Utility Model Content

[0007] Furthermore, the tank body includes a source inversion hole, a shielding valve hole and a shielding tank body; a source inversion hole is arranged at the center of the tank body, a shielding valve hole is arranged on one side of the shielding tank body, the shielding valve hole is connected with the source inversion hole, and the shielding valve is placed in the shielding valve hole.

[0008] Furthermore, the shielding valve includes a source storage hole and a shielding body. The source storage hole is arranged on the shielding body and is coaxially arranged with the inverted source hole and the source outlet hole. The shielding body is placed in the shielding valve hole and can rotate in the shielding valve hole.

[0009] Furthermore, the interior of the shield is lead-filled.

[0010] Furthermore, the interior of the tank is filled with lead.

[0011] The utility model provides a source inversion tank, which is composed of a tank body and a shielding valve. Through the coaxial source inversion hole, source storage hole and source outlet hole, the shielding valve can be turned to store the source and shield the radiation. The shielding valve is turned again and the switch baffle is opened to complete the source inversion. It has the advantages of safety and convenience in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figure 1 , 2 The structure of the specific embodiment of the utility model includes a tank body 1, a shielding valve 2 and a switch baffle 3. The shielding valve 2 is arranged on the side of the tank body 1 and is connected to the tank body 1. A source hole 1.4 is arranged at the bottom of the tank body 1, and a switch baffle 3 is arranged below the source hole 1.4.

[0022] See also Figure 3 The structure of the specific embodiment of the tank body 1 of the utility model mainly consists of a source inversion hole 1.1, a shielding valve hole 1.2, a shielding tank body 1.3 and a source outlet hole 1.4. The source inversion hole 1.1 is arranged at the center of the tank body 1, a shielding valve hole 1.2 is arranged on one side of the shielding tank body 1.3, the shielding valve hole 1.2 is connected to the source inversion hole 1.1, the shielding valve 2 is placed in the shielding valve hole 1.2, and a source outlet hole 1.4 is arranged at the bottom of the shielding tank body 1.3, and the source inversion hole 1.1 and the source outlet hole 1.4 are arranged coaxially.

[0023] Among them, the interior of the tank structure of the tank body 1 is filled with lead, which can effectively shield radiation.

[0024] See also Figure 4 The structure of the shielding valve 2 of the utility model mainly consists of a source storage hole 2.1 and a shielding body 2.2. The source storage hole 2.1 is arranged on the shielding body 2.2 and is coaxially arranged with the inverting source hole 1.1 and the source outlet hole 1.4. The shielding body 2.2 is placed in the shielding valve hole 1.2 and can rotate in the shielding valve hole 1.2.

[0025] The shielding body 2.2 is lead-filled inside and can effectively shield radiation.

[0026] When the utility model is used, the radioactive source is transported to the installation site by an organization with relevant qualifications in a source transport tank with shielding effect, and then the radioactive source in the source transport tank is placed in the source pouring hole 1.1. In the source pouring state, the source storage hole 2.1 of the shielding valve 2 is coaxial with the source pouring hole 1.1. After the radioactive source is placed in the source storage hole 2.1, the shielding body 2.2 is rotated to make the source storage hole 2.1 in a horizontal position, and it is in the source storage state. At this time, the shielding material of the shielding valve 2 and the tank body 1 wraps the radioactive source to effectively shield the radiation.

[0027] When loading the source, turn the shielding valve 2 to make the source storage hole 2.1 in a vertical state and coaxial with the source outlet hole 1.4. The radiation source falls on the switch baffle 3 through the source outlet hole 1.4. When loading the source, open the switch baffle 3 and the radiation source falls into the corresponding position of the equipment. During the whole process, the radiation source is always protected by the shielding body, ensuring that the radiation value is always in a safe state during the source reversal process.

[0028] The technical contents not specifically described in the present utility model and the above embodiments are the same as the prior art.

[0029] The above are only specific implementation methods disclosed in the present utility model, but the protection scope of the present utility model is not limited thereto. The protection scope of the present utility model shall be based on the protection scope of the claims.
