Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically the labyrinth structure of the probe in the shielding room of an X-ray irradiator. Background Technology
[0002] Currently, dose measurement in sealed X-ray irradiation chambers primarily involves irradiating the chamber with a membrane or alanine column, followed by reading the dose using specialized instruments. However, neither the membrane nor the alanine column is recyclable. Membrane measurements are inaccurate, and alanine readings require expensive third-party testing institutions, which are costly and time-consuming. Placing an ion-type probe in a lead chamber allows for real-time data readings, eliminating the need for additional equipment. Therefore, a solution is needed to design a channel within the sealed chamber for placing the probe, ensuring this channel does not compromise the X-ray shielding effectiveness. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a labyrinth structure for the probe in the shielded chamber of an X-ray irradiator. A channel is designed within the sealed shielded chamber to insert the probe, allowing for dose measurement inside the chamber. This improves measurement efficiency and data accuracy, and offers advantages such as simple structure and ease of use, thus solving the problems mentioned in the background section.
[0004] This utility model provides the following technical solution: a probe labyrinth structure for a shielded chamber of an X-ray irradiator, including a shielded chamber, one wall of which has a through hole, and a probe channel is provided on the outer side of the through hole. The probe channel is connected to the outer wall of the shielded chamber, one end of the probe channel has an inlet, and a leak-proof plug is provided on the outer side of the inlet of the probe channel. The leak-proof plug is detachably connected to the shielded chamber, and the gap between the leak-proof plug and the probe channel is larger than the diameter of the probe cable to accommodate the probe cable.
[0005] The anti-leakage plug is a hollow structure used to accommodate the end of the probe channel. When installed in place, the anti-leakage plug and the probe channel partially overlap in vertical space. The anti-leakage plug also has an inner plug, which is inserted into the probe channel. A first gap is left between the outer wall of the inner plug and the inner wall of the probe channel.
[0006] The inner diameter of the probe channel is greater than the larger of the probe diameter and the probe cable diameter.
[0007] The leak-proof plug includes at least four walls, wherein the first side wall and the second side wall are arranged opposite to each other, and one end of the first side wall and the second side wall abuts against the outer wall of the shielded room; the third top wall connects the first side wall and the second side wall; and the fourth end wall is directly opposite the inlet.
[0008] A second gap is left between the inner walls of the first sidewall, the second sidewall, and the third top wall and the corresponding outer wall on the probe channel. The second gap is larger than the diameter of the probe cable.
[0009] The second gap, the first sidewall, the second sidewall, the third top wall, and the outer wall of the probe channel form a concave channel.
[0010] When the anti-leakage plug is installed in place, the end face at the inlet of the probe channel and the inner wall of the fourth end wall do not contact each other, leaving a third gap for communication with the second gap, so that part of the probe cable is located in the second gap and the third gap.
[0011] The first gap is ≤1mm, and the third gap is larger than the diameter of the probe cable. The purpose of the first gap design is to reduce the radiation exiting from the probe channel inlet. Most of the radiation is refracted through the first gap, and further refracted through the second gap, thus preventing radiation leakage.
[0012] The inner plug has a cable channel on one side, which is a groove. The outer wall of the leak-proof plug has a tail base with a fixing screw hole. The leak-proof plug is fixed to the shielding chamber by screws.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention relates to a labyrinth structure for the X-ray irradiator's shielded chamber probe. A probe channel is designed within the sealed shielded chamber to house the probe. During use, a detachable leak-proof plug is removed, and the ion probe is inserted into the shielded chamber through the probe channel. The detachable leak-proof plug is then reinstalled, ensuring the shielded chamber remains leak-free. The gap between the detachable leak-proof plug and the probe channel is larger than the probe cable diameter, guaranteeing the probe can enter the shielded chamber without damaging the probe cable. This probe channel allows the probe to be inserted into the shielded chamber for dose measurement, improving measurement efficiency and data accuracy. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This invention improves upon existing X-ray irradiation instrument shielding rooms, primarily by the coordination between the probe and the shielding room. The shielding room is existing technology, and its specific structure will not be described in detail.
[0025] Specific Implementation Example 1: Please refer to Figure 1-6 The X-ray irradiator shielded chamber probe labyrinth structure includes a shielded chamber 1, with a through hole 3 on one side of the shielded chamber 1. In this specific embodiment, the through hole 3 is opened at the top of the shielded chamber 1, and a probe channel 2 is provided on the outside of the through hole 3. The probe channel 2 is connected to one wall of the shielded chamber 1. The interior of the probe channel 2 is a cuboid cavity, or a circular cavity, or a curved cavity, which is not limited. In this specific embodiment, this wall refers to the top wall of the shielded chamber 1. The probe channel 2 has an inlet at one end and the other end of the probe channel 2 is connected to the interior of the shielded chamber 1 through the through hole 3 on one wall of the shielded chamber 1. A leak-proof plug 4 is provided on the outside of the inlet of the probe channel 2. The leak-proof plug 4 and the shielded chamber 1 are detachable. The gap between the inner wall of the leak-proof plug 4 and the outer wall of the probe channel 2 is larger than the diameter of the probe cable.
[0026] The anti-leakage block 4 has a hollow structure and is used to accommodate the end of the probe channel 2. When the anti-leakage block 4 is installed in place, the anti-leakage block 4 and the probe channel 2 partially overlap in vertical space.
[0027] The anti-leakage plug also includes an inner plug 41, which is inserted into the probe channel, with a first gap between the outer wall of the inner plug 41 and the inner wall of the probe channel.
[0028] The inner diameter of probe channel 2 is larger than the larger of the probe diameter and the probe cable diameter. Because the probe, along with the probe cable connected to it, needs to pass through probe channel 2, this design ensures that regardless of whether the probe diameter or the probe cable diameter is larger, the width and height of the inner diameter of probe channel 2 are greater than the larger of the probe diameter and the probe cable diameter, guaranteeing that the probe can pass through probe channel 2.
[0029] The anti-leakage block 4 includes at least four walls, wherein the first side wall 5 and the second side wall 6 are arranged opposite to each other, and one end of the first side wall 5 and the second side wall 6 abuts against the outer wall of the shielding chamber 1, the third top wall 7 connects the first side wall 5 and the second side wall 6, and the fourth end wall 8 is directly opposite the inlet.
[0030] A second gap 9 is left between the inner walls of the first sidewall 5, the second sidewall 6 and the third top wall 7 and the corresponding outer wall on the probe channel 2. The second gap 9 is larger than the diameter of the probe cable.
[0031] like Figure 4 As shown, the second gap 9, the first sidewall 5, the second sidewall 6, and the third top wall 7 form a concave channel with the outer wall of the probe channel 2. The concave channel prevents radiation leakage.
[0032] like Figure 5 As shown, when the anti-leakage plug 4 is installed in place, the end face at the inlet of the probe channel 2 and the inner wall of the fourth end wall do not contact each other, leaving a third gap 10 for communication with the second gap 9, so that part of the probe cable is located in the second gap 9 and the third gap 10.
[0033] The first gap is ≤1mm, and the third gap is larger than the diameter of the probe cable. The purpose of the first gap design is to reduce the radiation emanating from the probe channel inlet. Most of the radiation is refracted through the first gap, and then further refracted through the second gap, i.e., the concave channel, thus preventing radiation leakage.
[0034] The inner plug 41 has a cable channel 42 on one side, which is a groove. The outer wall of the leak-proof plug 4 has a tail base 43, and the tail base 43 has a fixing screw hole 44. The leak-proof plug 4 is fixed to the shielding chamber 1 by screws.
[0035] In use, the removable anti-leakage block 4 is removed, and the ion probe is inserted into the shielding chamber 1 through the probe channel 2. The removable anti-leakage block 4 is then installed back in its original position. The screws, nuts, and fixing screw holes 44 are used to fix the anti-leakage block 4 to the shielding chamber 1. The inner wall of the fourth end wall 8 of the anti-leakage block 4 does not contact the end wall at the inlet of the probe channel 2, leaving space, i.e., the third gap, for the probe cable. Since the first gap between the inner block 41 and the probe channel is less than or equal to 1mm, and the second gap between the anti-leakage block and the probe channel, the shielding chamber 1 can be guaranteed not to leak. The gap between the removable anti-leakage block 4 and the probe channel 2 is greater than the diameter of the probe cable, ensuring that the probe can enter the shielding chamber 1 without damaging the probe cable.
[0036] This channel allows the probe to be inserted into the shielded chamber 1 for dose measurement, improving measurement efficiency and data accuracy.
