Description

Technical Field

[0001] This utility model relates to a daily necessities, specifically to a multi-channel ionization chamber installation device. Background Technology

[0002] An ionization chamber is a detector that measures ionizing radiation by utilizing the ionization effect. It consists of electrodes at different potentials and a medium between them. Ionizing radiation produces ion pairs in the medium. Under the influence of an electric field, the positive and negative ions drift towards the negative and positive electrodes, respectively, forming an ionizing current. Since the ionizing current is proportional to the intensity of the radiation, the intensity of the ionizing radiation can be obtained by measuring this current.

[0003] In the medical field, ionization chambers are mainly used to calibrate the output dose during radiotherapy to ensure that the radiation dose received by the patient is accurate. They can also be used as quality control equipment to ensure that the imaging dose meets safety standards.

[0004] During use, the ionization chamber needs to be positioned in a specific location within the radiation environment in a specific posture. Therefore, the ionization chamber needs to be installed and fixed. However, the existing installation and fixing structures for ionization chambers are generally complex, cumbersome to adjust, and difficult to coordinate the operation of multiple ionization chambers. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a multi-channel ionization chamber installation device, which has the advantages of simple structure and convenient installation and adjustment, and can be well adapted to the working conditions of multiple ionization chambers working together.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-channel ionization chamber installation device, comprising a pre-assembly assembly, a clamping assembly, and a detection support assembly, wherein the clamping assembly comprises a clamping block, wherein a plurality of mounting holes are distributed on the clamping block, the mounting holes being disposed through the clamping block vertically, and a clamping unit made of elastic material is provided in the mounting holes; the lower end surface of the clamping block is a positioning surface, and a first docking unit is provided on the clamping block;

[0007] The pre-assembled component includes an adjustment block, which has an upwardly oriented reference surface and reference holes on the reference surface, with each reference hole corresponding to a mounting hole; the adjustment block also has a second docking unit.

[0008] The detection support assembly includes a support base, on which a third docking unit is provided;

[0009] In the pre-installed state, the clamping block is connected to the adjusting block through the first docking unit and the second docking unit, wherein the positioning surface is set opposite to the reference surface, and the mounting hole is aligned with the reference hole; in the testing state, the clamping block is connected to the support base through the first docking unit and the third docking unit.

[0010] Before radiation testing, the clamping block and adjusting block are first connected via the first and second docking units, aligning the mounting holes with the reference holes. Then, the ionization chambers are inserted one by one into the mounting holes until the lower end of each chamber is inserted into the reference hole and contacts its bottom, achieving axial positioning. The clamping unit limits the movement of the ionization chamber, completing the pre-installation. During radiation testing, the support base is installed on the matching fixing device inside the treatment room. The pre-installed clamping block and adjusting block are separated and simultaneously transferred to the support base along with the ionization chamber, completing the installation of the ionization chamber and allowing subsequent radiation measurement operations to proceed.

[0011] The multi-channel ionization chamber installation device of this application uses clamping blocks and clamping units to clamp and install the ionization chambers, which is simple in structure and convenient to operate. The installation, positioning, and adjustment of the ionization chambers are achieved through pre-installation operations, which can effectively ensure the installation accuracy of the ionization chambers relative to the clamping blocks, as well as the relative accuracy between each ionization chamber, and can well adapt to the working conditions of multi-channel ionization chambers working together.

[0012] Preferably, at least one side of the clamping block is provided with a reference line, and the reference line includes at least a transverse reference line and a longitudinal reference line.

[0013] The baseline can serve as a positional reference for the clamping block and support base, facilitating the adjustment of the ionization chamber's installation position within the treatment room.

[0014] Preferably, the upper and lower ends of the clamping block are inclined relative to each other. This irregular shape of the clamping block can indicate the installation orientation of the ionization chamber within the treatment room, preventing incorrect installation.

[0015] Preferably, the clamping block is made of acrylic material, which not only achieves a lightweight design but also effectively prevents radiation activation.

[0016] Preferably, the top surface of the clamping block is provided with indicator marks corresponding to the clamping holes. This allows for the marking of each ionization chamber, facilitating measurement operations.

[0017] Preferably, the first docking unit includes a docking lug disposed on the side of the clamping block, the docking lug having a first limiting hole, the lower end face of the docking lug being a first docking surface, and the mounting hole being disposed perpendicular to the first docking surface.

[0018] Preferably, the second docking unit includes a docking boss mounted on the adjusting block, the top surface of the docking boss being the second docking surface, and the second docking surface having a second limiting hole; in the pre-installed state, the first docking surface is in contact with the second docking surface, the first limiting hole is aligned with the second limiting hole, and is limited by screws or pins.

[0019] Preferably, the reference surface is located on one side of the mating boss and is inclined relative to the second mating surface, and the reference hole is perpendicular to the second mating surface; the reference holes are divided into several groups, and each group of reference holes is distributed sequentially along the inclined direction of the second mating surface, and the bottom surface of different groups of reference holes is at a different distance from the second mating surface.

[0020] The different depths of the reference holes correspond to different installation heights of each ionization chamber relative to the clamping block. By sealing the space of the ionization chamber, the radiation dose at each location can be measured more accurately, ensuring that the radiation dose received by the patient during treatment is precise.

[0021] Preferably, the third docking unit includes a support column mounted on a support base, the top surface of the support column being the third docking surface, and a third limiting hole being provided on the third docking surface; in the detection state, the first docking surface is in contact with the third docking surface, the first limiting hole is aligned with the third limiting hole, and is limited by screws or pins.

[0022] Preferably, the clamping block includes an upper clamping block and a lower clamping block, which are stacked one on top of the other and detachably connected; the clamping unit includes an O-ring disposed between the upper clamping block and the lower clamping block.

[0034] like Figure 3 and Figure 4 As shown, the upper and lower ends of the clamping block are inclined relative to each other. The irregular shape of the clamping block can indicate the installation orientation of the ionization chamber within the treatment room, avoiding incorrect installation.

[0035] The clamping block is made of acrylic material, which not only enables a lightweight design but also effectively prevents radiation activation. The top surface of the clamping block has indicator marks corresponding to the clamping holes, allowing for the identification of each ionization chamber and facilitating measurement operations.
