Description
Technical Field
The utility model relates to a protector, especially a special radiotherapy of tumor-bearing mouse
Protector belongs to experimental facilities technical field.
Background
When the tumor-bearing mouse is used as a tumor mouse model for radiotherapy experiments, a certain difficulty is brought to the experiments because a proper fixing device is not provided. The applicant finds that the fixing devices in the prior art, such as CN203341847U, a multi-layer protection type rat radiotherapy fixing frame, CN203342222U and a protection type rat radiotherapy fixing frame, both disclose the fixing device for fixing tumor-bearing mice in radiotherapy experiments, and ensure the smooth progress of the experiments. However, the posture fixation alone does not satisfy all the requirements of radiotherapy experiments, such as: no radiation protection to non-radiotherapy regions during radiotherapy; the fixing mode is that the shape of the groove is fixed, the placing position of the mouse is fixed, and the fixing mode is not suitable for radiotherapy of the implanted tumor under the lateral hypochondrium commonly adopted by the tumor-bearing mouse; excessive posture control is not beneficial to the rat to keep comfortable in the radiotherapy process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: aiming at the problems of ray protection and body position fixation in the tumor-bearing mouse radiotherapy experiment in the prior art, the special radiotherapy protection device for the tumor-bearing mouse is provided, and the damage and the experiment error of the mouse caused by the radiation of other parts of the body and the body position problem are reduced to the maximum extent.
In order to achieve the purpose, the utility model discloses a special radiotherapy protector of tumor-bearing mouse, including the plumbous system dustcoat that is used for placing the mouse, be equipped with the hole on the plumbous system dustcoat, downthehole hollow hole round pin of settling, the hole round pin has one at least.
Furthermore, the lead outer cover is a hollow lead barrel, a mouse placing position is arranged on the inner surface of the lead barrel, the barrel wall opposite to the placing position is provided with the hole, and the barrel outer wall on the same side as the placing position is a plane. The design can not only meet the requirement that other parts are not radiated, but also ensure that the position of the hole is stably positioned above in the experimental process.
Still further, the length of the lead barrel is 14-16 cm. The hole round pin cup joints in proper order, the hole round pin that the aperture successive layer shrank, the upper surface of hole round pin has along the hole edge of circumference extension, the hole cooperatees with the biggest hole round pin size in aperture. The diameter of the hole pin is 1cm, 2cm, 3cm and 4cm from inside to outside in sequence. The hole pin is made into a movably adjustable piston type exposed hole, and the size of the hole pin can be adjusted according to the requirement of the irradiated area of the mouse, so that the area which does not need to be irradiated is protected as much as possible.
When the tumor-bearing mouse is used, after anesthesia, any body position is selected according to the radiotherapy position requirement, so that the area needing irradiation faces to the radiotherapy radiation rays from the upper source.
The utility model has the advantages of simple and exquisite structure, convenient to use mainly is to the conventional tumour planting region of 20-30g tumor-bearing mouse: hypochondriac tumors, tumors on the hip side, and abdominal metastases. Can adjust the body part and the exposure area of the mouse directly exposed to the radiation, and reduce the damage and experimental error of the mouse caused by the radiation of other parts of the body to the maximum extent.

Detailed Description
Example one
The structure of the special radiotherapy protector for tumor-bearing mice of this embodiment is as shown in fig. 1 to 4, including the lead outer cover for placing the mice, the lead outer cover is hollow lead bucket 1 in this embodiment, lead bucket 1 is provided with hole 2, the hollow hole pin is arranged in the hole, the hole pin is 4 hole pins a-D that cup joint in proper order and the aperture layer-by-layer shrinks, the internal surface of lead bucket 1 is provided with mouse placing part 3, the diameter of hole pin D-hole pin a is 1cm, 2cm, 3cm, 4cm from inside to outside in proper order. The upper surface of each hole pin has a circumferentially extending hole rim 5, and the hole 2 is sized to fit the largest hole pin a. The hole 2 is positioned on the barrel wall opposite to the placing position, and the barrel outer wall on the same side with the placing position is a plane 4. The design can not only meet the requirement that other parts are not radiated, but also ensure that the position of the hole is stably positioned above in the experimental process. The length of the lead barrel is 14-16 cm. The hole pin is made into a movably adjustable piston type exposed hole, and the size of the hole pin can be adjusted according to the requirement of the irradiated area of the mouse, so that the area which does not need to be irradiated is protected as much as possible.
When the device is used, after a tumor-bearing mouse is anesthetized, any body position is selected according to the requirement of a radiotherapy position so that an area needing irradiation faces to radiotherapy radiation rays from an upper source, and a single hole pin or a plurality of hole pins are selected to be matched for use according to the size of the position to be irradiated according to the experiment requirement.
In addition to the above embodiments, the present invention may have other embodiments. All technical schemes formed by adopting equivalent replacement or equivalent transformation, such as the number of the hole pins and the like, fall within the protection scope required by the utility model.
