Description

Technical Field

[0001] This application relates to the field of radiation distribution measurement technology, and in particular to an X-ray dose measurement device for a dental X-ray machine. Background Technology

[0002] In today's era, with the significant improvement in living standards and the rapid development of technology, dental X-ray machines are increasingly widely used in the field of oral medicine. They have become a crucial tool in the diagnosis of oral diseases, accurately revealing the fine internal structure of teeth, the condition of periodontal tissues, and various lesions of the jawbone. This provides dentists with an indispensable basis for developing scientific and reasonable treatment plans, greatly promoting the improvement of the quality of oral medical services and the development of the industry.

[0003] However, during the use of dental X-ray machines, the effective X-ray dose must be strictly controlled within the prescribed range, which is related to patient health and safety as well as the standardization of medical operations. Existing measurement methods mostly rely on general-purpose measurement tools, lacking a specialized measurement system tailored to the characteristics of dental X-ray machines. On the one hand, the measurement equipment lacks precise positioning and adaptation structures. When measuring X-rays from a dental X-ray machine, it is difficult to ensure that the X-ray generator is in a standard and stable measurement position, easily leading to positional deviations. This results in significant uncertainty and error in the measurement results, failing to accurately reflect the true effective dose output level of the dental X-ray machine, and hindering quality control and calibration during the production process. On the other hand, when exploring the relationship between the effective X-ray dose and different factors (such as distance and angle), the lack of flexible and precise adjustment mechanisms makes it difficult to simulate various variables that may occur in actual use scenarios, making it difficult to provide comprehensive and reliable data support for the safe use of dental X-ray machines in different clinical application scenarios. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an X-ray dose measurement device for dental X-ray machines, which can improve the stability, flexibility, and versatility of X-ray dose measurement.

[0005] This application provides an X-ray dose measurement device for a dental X-ray machine, comprising:

[0006] A base plate, wherein a first mounting area and a second mounting area are provided along a first direction, and the first mounting area is provided with a positioning structure;

[0007] An X-ray generator, wherein the X-ray generator is detachable and is disposed on the first mounting area in cooperation with the positioning structure, and the emission port of the X-ray generator faces the second mounting area;

[0008] The mounting bracket is detachably disposed in the second mounting area, and the length of the second mounting area in the first direction is greater than the length of the mounting bracket in the first direction, so that the distance between the mounting bracket and the X-ray generator can be adjusted.

[0009] A measuring probe is disposed within the mounting bracket, and the probe's detection port is opposite to the X-ray generator's emission port.

[0010] The dental X-ray dose measurement device according to the embodiments of this application has at least the following beneficial effects: A first mounting area and a second mounting area are provided on the base plate along a first direction. The positioning structure of the first mounting area can accurately determine the position of the X-ray generator, allowing it to be detachably and stably mounted on the first mounting area, ensuring that the position height of the X-ray generator is consistent during each measurement. A mounting bracket is detachably disposed in the second mounting area, and a measuring probe is mounted inside the bracket with its detection port facing the emission port of the X-ray generator. Since the length of the second mounting area in the first direction is greater than the length of the mounting bracket in the first direction, the distance between the second mounting area and the X-ray generator can be easily adjusted by sliding the mounting bracket. During adjustment, the spatial interval between the two is changed with millimeter-level precision. Based on the physical principle that X-ray intensity is inversely proportional to the square of the distance, the X-ray dose at different distances is measured by precisely adjusting the distance. After receiving X-rays, the measuring probe converts the energy information of the rays into electrical or digital signals, processes and analyzes the signals, and finally obtains the X-ray dose value. In this application, a specially designed positioning structure on the base plate firmly fixes the X-ray generator in a specific position, eliminating measurement errors caused by generator positional movement or offset. The length difference design between the second mounting area and the mounting bracket enables a simple and efficient distance adjustment function. It can flexibly simulate the distance changes between the X-ray generator and the measurement object (such as a patient's oral tissue) under different clinical usage scenarios, accurately measuring X-ray dose under various distance conditions. The overall structural design of the device takes into account different models and specifications of dental X-ray generators. Through detachable installation methods, such as the positioning structure of the first mounting area and the detachable mounting bracket, it can be easily adapted to various dental X-ray machines and various measurement probes, improving the versatility of the measuring device.

[0011] According to some embodiments of this application, the second installation area is provided with an elongated mounting hole along the first direction, and the mounting bracket is provided with a fixing hole that matches the elongated mounting hole.

[0012] According to some embodiments of this application, the second installation area is provided with two mounting elongated holes, the two mounting elongated holes respectively corresponding to the positions on both sides of the mounting bracket, and the mounting bracket is provided with fixing holes on both sides.

[0013] According to some embodiments of this application, it also includes multiple mounting brackets of different specifications, and each mounting bracket corresponds to a measuring probe of different specifications, and the distance between the two fixing holes on both sides of each mounting bracket is equal.

[0014] According to some embodiments of this application, the second mounting area has a scale line on the side of at least one of the mounting elongated holes, the scale line being used to indicate the distance between the measuring probe and the X-ray generator.

[0015] According to some embodiments of this application, the mounting bracket has an indicator mark on the side near the scale line, and the position of the indicator mark is opposite to the emission port of the measuring probe.

[0016] According to some embodiments of this application, the positioning structure includes at least two positioning posts, each of which corresponds to a position on one side of the X-ray generator, so as to hold the X-ray generator between the two positioning posts.

[0017] According to some embodiments of this application, the positioning structure further includes a positioning plate, which is disposed on the side of the first installation area close to the second installation area. The top of the positioning plate is provided with a slot that matches the emission port of the X-ray generator, and the emission port of the X-ray generator is engaged in the slot.

[0018] According to some embodiments of this application, the base plate is provided with a recess, and the second mounting area is located within the recess.

[0031] In today's era, with the significant improvement in living standards and the rapid development of technology, dental X-ray machines are increasingly widely used in the field of oral medicine. They have become a crucial tool in the diagnosis of oral diseases, accurately revealing the fine internal structure of teeth, the condition of periodontal tissues, and various lesions of the jawbone. This provides dentists with an indispensable basis for developing scientific and reasonable treatment plans, greatly promoting the improvement of the quality of oral medical services and the development of the industry.

[0032] However, during the use of dental X-ray machines, the effective X-ray dose must be strictly controlled within the prescribed range, which is related to patient health and safety as well as the standardization of medical operations. Existing measurement methods mostly rely on general-purpose measurement tools, lacking a specialized measurement system tailored to the characteristics of dental X-ray machines. On the one hand, the measurement equipment lacks precise positioning and adaptation structures. When measuring X-rays from a dental X-ray machine, it is difficult to ensure that the X-ray generator is in a standard and stable measurement position, easily leading to positional deviations. This results in significant uncertainty and error in the measurement results, failing to accurately reflect the true effective dose output level of the dental X-ray machine, and hindering quality control and calibration during the production process. On the other hand, when exploring the relationship between the effective X-ray dose and different factors (such as distance and angle), the lack of flexible and precise adjustment mechanisms makes it difficult to simulate various variables that may occur in actual use scenarios, making it difficult to provide comprehensive and reliable data support for the safe use of dental X-ray machines in different clinical application scenarios.

[0033] Based on this, this application provides an X-ray dose measurement device for a dental X-ray machine to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0034] Reference Figure 1 , Figure 3 and Figure 4 This application provides an X-ray dose measurement device for a dental X-ray machine, comprising: a base plate 100, an X-ray generator 200, a mounting bracket 300, and a measuring probe 400. The base plate 100 is provided with a first mounting area and a second mounting area along a first direction, and the first mounting area is provided with a positioning structure. The X-ray generator 200 is detachably mounted on the first mounting area in cooperation with the positioning structure, and the emission port of the X-ray generator 200 faces the second mounting area. The mounting bracket 300 is detachably mounted on the second mounting area, and the length of the second mounting area in the first direction is greater than the length of the mounting bracket 300 in the first direction, so that the distance between the mounting bracket 300 and the X-ray generator 200 can be adjusted. The measuring probe 400 is disposed inside the mounting bracket 300, and the detection port of the measuring probe 400 is opposite to the emission port of the X-ray generator 200.

[0035] The base plate 100 has a first mounting area and a second mounting area along a first direction. The positioning structure of the first mounting area can accurately determine the position of the X-ray generator 200, allowing it to be detachably and stably mounted on the first mounting area, ensuring that the position and height of the X-ray generator 200 are consistent during each measurement. The mounting bracket 300 is detachably mounted in the second mounting area, and the measuring probe 400 is mounted inside the bracket with its detection port facing the emission port of the X-ray generator 200. Since the length of the second mounting area in the first direction is greater than the length of the mounting bracket 300 in the first direction, the distance between the mounting bracket 300 and the X-ray generator 200 can be easily adjusted by sliding the mounting bracket 300. During the adjustment process, the spatial interval between the two is changed with millimeter-level precision. Based on the physical principle that X-ray intensity is inversely proportional to the square of the distance, the X-ray dose at different distances is measured by precisely adjusting the distance. After receiving X-rays, the measuring probe 400 converts the energy information of the rays into electrical or digital signals, processes and analyzes the signals, and finally obtains the X-ray dose value. In this application, a specially designed positioning structure on the base plate 100 firmly fixes the X-ray generator 200 in a specific position, eliminating measurement errors caused by generator positional movement or offset. The length difference between the second mounting area and the mounting bracket 300 enables a simple and efficient distance adjustment function. This allows for flexible simulation of distance changes between the X-ray generator 200 and the measurement object (such as patient oral tissue) under different clinical usage scenarios, accurately measuring X-ray dose under various distance conditions. The overall structural design of the device considers different models and specifications of dental X-ray generators 200. Through detachable installation methods, such as the positioning structure of the first mounting area and the detachable mounting bracket 300, it can be easily adapted to various dental X-ray machines and various measuring probes 400, improving the versatility of the measuring device.

[0036] Continue to refer to Figure 1 , Figure 3 and Figure 4 It is understood that a mounting elongated hole 110 is provided in the second installation area along the first direction, and a fixing hole matching the mounting elongated hole 110 is provided on the mounting bracket 300. The design of the mounting elongated hole and the fixing hole provides a flexible positioning method for the mounting bracket 300. The mounting elongated hole 110 provided along the first direction allows the mounting bracket 300 to move within a certain range. By adjusting the position of the fixing hole in the elongated hole, the distance between the mounting bracket 300 and the X-ray generator 200 can be changed with a relatively fine scale, and the stability of the position adjustment of the mounting bracket 300 can be improved.

[0037] Understandably, the second mounting area is provided with two elongated mounting holes 110, which correspond to the positions on both sides of the mounting bracket 300. The mounting bracket 300 has fixing holes on both sides. The two elongated mounting holes 110, located on both sides of the mounting bracket 300, provide more balanced support for the mounting bracket 300. When the mounting bracket 300 is fixed to the base plate 100, the cooperation between the fixing holes and the elongated mounting holes 110 effectively distributes the pressure borne by the mounting bracket 300. Simultaneously, the two elongated mounting holes 110 provide more precise parallel guidance for the movement of the mounting bracket 300. When adjusting the distance between the mounting bracket 300 and the X-ray generator 200, the elongated holes on both sides ensure that the mounting bracket 300 moves along a predetermined parallel direction, improving the stability of dose measurement.

[0038] Reference Figure 1 and Figure 3 It is understood that the dental X-ray dose measurement device provided in this application also includes multiple mounting brackets 300 of different specifications, and each mounting bracket 300 corresponds to a measurement probe 400 of different specifications. The distance between the two fixing holes on both sides of each mounting bracket 300 is equal. Including multiple mounting brackets 300 of different specifications and corresponding measurement probes 400 allows the device to adapt to various measurement needs. Measurement probes 400 of different specifications may have different sensitivities, detection ranges, or energy response characteristics, which can meet the requirements for accurate measurement of X-ray dose from various types of dental X-ray machines. For example, for dental X-ray machines with different power and different radiation energy distributions, a suitable measurement probe 400 can be selected for measurement, thereby improving the device's compatibility with different dental X-ray machine models and performance. The design of equal spacing between the fixing holes on both sides of each mounting bracket 300 ensures consistency during installation. This means that regardless of the specification of the mounting bracket 300 used, their installation method and stability in the second installation area are similar. This standardized design allows operators to quickly change and install different mounting brackets 300 and measuring probes 400 without having to readjust or adapt to new installation methods, thus improving work efficiency.

[0039] Reference Figure 1 and Figure 2 Understandably, the second mounting area has a scale line 120 on the side of at least one mounting elongated hole 110. The scale line 120 is used to mark the distance between the measuring probe 400 and the X-ray generator 200. The scale line 120 allows the operator to directly read the distance between the measuring probe 400 and the X-ray generator 200. When conducting dose-distance relationship studies or simulating different clinical imaging distances, no additional measuring tools are needed to determine the distance, improving the convenience of measurement recording.

[0040] Reference Figure 2 Understandably, the mounting bracket 300 has an indicator 310 on the side near the scale line 120, with the indicator 310 positioned opposite the emission port of the measuring probe 400. The indicator 310's position relative to the emission port of the measuring probe 400 is fixed and clearly defined. When reading the scale line 120, the operator can quickly and accurately determine the distance between the measuring probe 400 and the X-ray generator 200 using the indicator 310. This precise positioning method avoids reading errors caused by differences in viewing angle or manual estimation, ensuring accurate and reliable distance values ​​every time, especially when high-precision distance measurements are required.

[0041] Reference Figure 1 , Figure 3 and Figure 4 It is understood that the positioning structure includes at least two positioning posts 131, each corresponding to a position on either side of the X-ray generator 200, thus securing the X-ray generator 200 between the two positioning posts 131. The two positioning posts 131, located on either side of the X-ray generator 200, effectively hold it in place. This dual-sided positioning method precisely determines the position of the X-ray generator 200. During dose measurement, even minute displacements of the X-ray generator can affect the accuracy of the measurement results. This positioning method effectively avoids errors caused by generator positional shifts, ensuring that the X-ray emission source position is consistent for each measurement, thereby improving measurement accuracy. Furthermore, this dual-sided positioning structure simplifies and facilitates the installation and removal of the X-ray generator 200. Operators only need to place the X-ray generator 200 between the two positioning posts 131 for quick installation. When maintenance, calibration, or replacement is required, it can be easily removed from between the positioning posts 131 without complex installation tools or cumbersome procedures, thus improving work efficiency.

[0042] Reference Figure 4It is understood that the positioning structure also includes a positioning plate 132, which is located on the side of the first installation area near the second installation area. The top of the positioning plate 132 has a slot that matches the emission port of the X-ray generator 200, and the emission port of the X-ray generator 200 is engaged in the slot. The slot design not only fixes the position of the emission port but also ensures its angle, ensuring that the angle of X-ray emission remains consistent each time the X-ray generator 200 is installed. Simultaneously, when the X-ray generator 200 is installed on the device, the emission port being engaged in the slot effectively prevents it from shaking during operation, ensuring that the rays propagate stably to the measuring probe 400 in the predetermined direction. This reduces measurement errors caused by emission port instability and improves the stability and reliability of the entire measuring device.

[0043] Reference Figure 1 and Figure 4 It is understood that the base plate 100 has a recess 140, and the second mounting area is located within the recess 140. The recess 140 is used to lock the mounting bracket 300 in place, enabling precise installation and positioning of the mounting bracket 300 on the base plate 100, and also fixing the angle of the mounting bracket 300 to a certain extent. During the use of the device, especially under conditions that may be subject to vibration or other external interference, the locking of the mounting bracket 300 by the recess 140 can effectively prevent its displacement.

[0044] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
