[0072] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.
[0073] Please refer to Figures 1 to 24 , an embodiment of the present application provides a detector, and the detector includes a housing assembly, a detection assembly, and a shielding assembly; the following will be described in detail.
[0074] The detection assembly includes a flat housing 21, a detection circuit board 22, and a probe (not shown in the figure); wherein, the detection circuit board 22 is disposed in the flat housing 21 and electrically connected to the first end of the probe, and the detection circuit board 22 includes a sensitive element 221; the first end of the probe is fixed in the flat housing 21, and the second end of the probe extends out of the flat housing 21;
[0075] The housing assembly includes a contact housing and a pressing portion that can slide relative to each other, and the detection assembly is located below the bottom of the pressing portion; wherein, the contact housing is used to abut against the sampling site, and the pressing portion is used to drive the detection assembly to move towards the sampling site to insert the probe into the sampling site, and the detection signal of the probe is transmitted to the detection circuit board 22;
[0076] The shielding assembly is disposed on one side surface of the flat housing 21; when the detector is sterilized by irradiation rays, the shielding assembly is used to block part of the irradiation rays to form a penumbra shielding area 801 that protects the sensitive element 221.
[0077] The sensitive element 221 is a high-precision electronic component that is prone to failure due to being affected by irradiation rays.
[0078] The irradiation rays include but are not limited to X-rays, electron beams, and gamma rays.
[0079] When the irradiation rays shoot from one side of the flat housing 21 towards the sensitive element 221 on the detection circuit board 22, the shielding assembly can block the irradiation rays shooting towards the sensitive element 221 and form a penumbra shielding area 801 that is not affected by the irradiation rays. Adjust the position and size of the shielding assembly so that the penumbra shielding area 801 formed by the shielding assembly covers the sensitive element 221, weakening or eliminating the irradiation influence of the irradiation rays on the sensitive element 221, thereby alleviating the situation where the sensitive element 221 fails due to being affected by irradiation and the detection circuit board 22 cannot work properly. That is, the present application can also protect the detection circuit board 22 from being damaged while ensuring the sterilization of the detector by irradiation rays.
[0080] In this embodiment, when sterilizing the detector, the detector can be placed below the irradiation source so that the penumbra shielding area 801 formed by the shielding assembly wraps the sensitive element 221.
[0081] Specifically, the cross-section of the penumbra shielding area 801 formed by the shielding assembly is triangular or polygonal.
[0082] Please refer toFigures 1 to 6 In an optional embodiment, the probe is brought into the sampling site via a guide needle 25;
[0083] The abutment housing comprises a first cylindrical support 11;
[0084] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a supporting bracket 13 and an elastic member 14;
[0085] The first cylindrical support 11 is partially slidably located in the pressing shell 105, and the inner wall of the first cylindrical support 11 is provided with a protrusion 112;
[0086] The second cylindrical bracket 12 is slidably sleeved in the first cylindrical bracket 11, and the second cylindrical bracket 12 comprises a cylindrical structure 121 and a bottom plate 122 at the bottom thereof; the cylindrical structure 121 is provided with a guide hole 1211 along the axial direction, and a positioning hole 1213 is provided on the path of the guide hole 1211; a plurality of connecting parts 1221 extend from the outer edge of the bottom plate 122, and the plurality of connecting parts 1221 are fixedly connected to the pressing shell 105;
[0087] The support bracket 13 is located in the cylindrical structure 121, and the support bracket 13 has an elastic abutment portion 131 extending outward;
[0088] The elastic member 14 is compressed between the bottom plate 122 and the top of the supporting bracket 13;
[0089] Wherein, in the initial state, the elastic member 14 is in a compressed state, and the elastic abutment portion 131 is located in the positioning hole 1213;
[0090] Under the action of external force, the pressing shell 105 drives the second cylindrical bracket 12 to move relative to the first cylindrical bracket 11, so that the protrusion 112 moves along the guide hole 1211; when the second cylindrical bracket 12 moves to the first predetermined position relative to the first cylindrical bracket 11, the guide needle 25 guides the probe to penetrate the sampling site; when the second cylindrical bracket 12 moves to the second predetermined position relative to the first cylindrical bracket 11, the protrusion 112 squeezes the elastic abutment 131 out of the positioning hole 1213, and the elastic member 14 is released, driving the guide needle 25 to leave the sampling site through the support bracket 13.
[0091] In this embodiment, the elastic member 14 can be a spring. Since the elastic member 14 is compressed between the bottom plate 122 and the top of the support bracket 13, that is, the elastic member 14 will exert an elastic force on the second cylindrical bracket 12 and the support bracket 13 to move them away from each other. However, since the elastic abutting portion 131 is located in the positioning hole 1213, the elastic force generated by the elastic member 14 will push the elastic abutting portion 131 against the inner wall of the positioning hole 1213, so that the second cylindrical bracket 12 and the support bracket 13 are relatively stationary.
[0092] Specifically, the detector can be used to detect a variety of body index data. In the following embodiments, blood glucose detection is taken as an example.
[0093] When the user uses the detector to detect blood glucose, hold the pressing shell 105 and align it with the sampling site, so that one end of the abutting shell abuts near the sampling site. At this time, the guiding needle 25 does not contact the sampling site. Then, push the pressing shell 105 to move towards the side close to the sampling site. Since the pressing shell 105 is connected to the second cylindrical bracket 12, and the support bracket 13 abuts against the second cylindrical bracket 12 through the elastic abutting portion 131, when the pressing shell 105 drives the second cylindrical bracket 12 to move, it can further drive the support bracket 13 and the detection component to move towards the side close to the sampling site. During the process of the second cylindrical bracket 12 driving the detection component to move, the guiding needle 25 in the detection component gradually approaches the sampling site until the second cylindrical bracket 12 moves to the first predetermined position, and the guiding needle 25 pierces the sampling site. The probe follows the guiding needle 25 to pierce, so as to sample through the probe, and the probe transmits the data to the detection circuit board 22 to detect the blood glucose index.
[0094] The user continues to push the pressing shell 105 to move towards the side close to the sampling site until the second cylindrical bracket 12 reaches the second predetermined position. At this time, the convex portion 112 extrudes the elastic abutting portion 131 out of the positioning hole 1213, and the elastic abutting portion 131 no longer abuts against the hole wall of the positioning hole 1213. The support bracket 13 will no longer be limited by the second cylindrical bracket 12. The elastic force generated by the compressed elastic member 14 will push the support bracket 13 towards the side away from the sampling site, so as to drive the guiding needle 25 away from the sampling site, so as to quickly pull out the guiding needle 25 from the sampling site. Since the detection component is not connected to the support bracket 13, the probe will not be pulled out of the sampling site together with the guiding needle 25, but remains in the sampling site to be able to continuously sample and detect, so as to dynamically feedback the detection result.
[0095] With the structure of the above detector, the user can push the pressing shell 105, and insert the detection needle into the sampling site through the guiding needle 25. After the guiding needle 25 brings the detection needle into the sampling site to a certain depth, the supporting bracket 13 is no longer limited by the second cylindrical bracket 12, and the spring is released to quickly pull out the guiding needle 25 along the insertion path from the sampling site, which is not likely to cause situations such as deviation from the trajectory and slow needle retraction, resulting in strong pain and skin damage to the person to be detected, thus improving the experience of the person to be detected.
[0096] Further, in this embodiment, the shielding component includes a shielding block fixing structure 31 and a shielding block 80;
[0097] The shielding block fixing structure 31 is fixed above the bottom plate 122, and a shielding block receiving groove 311 is provided on the shielding block fixing structure 31;
[0098] The shielding block 80 is detachably received in the shielding block receiving groove 311, and is used to block the irradiation rays to form a penumbra shielding area 801 in a specified area.
[0099] It can be understood that after the irradiation sterilization of the detector is completed, the shielding block 80 can be taken out from the shielding block receiving groove 311, or can be retained in the detector.
[0100] Specifically, the shielding block 80 is a cuboid structure. The density of the shielding block 80 is greater than 1000 kg / m³. It can be understood that the greater the density of the shielding block 80, the better the effect of the shielding block 80 in blocking the irradiation rays.
[0101] It should be noted that although the shielding block 80 can block the irradiation rays, it also weakens the sterilization intensity of the irradiation rays on the penumbra shielding area 801. There may be insufficient sterilization intensity, and it is impossible to completely sterilize the penumbra shielding area 801, resulting in bacteria still existing in the penumbra shielding area 801 in the detector after irradiation sterilization, and then contaminating other areas of the detector.
[0102] Based on the above problems, in this embodiment, the detector further includes a sealing shell 40. The sealing shell 40 is located between the bottom plate 122 and the flat shell 21. The outer walls of the sealing shell 40 and the flat shell 21 form a first sealing cavity (not labeled in the figure), and the first sealing cavity is correspondingly arranged with the shielding component.
[0103] Preferably, the cross-section of the first sealing cavity is greater than or equal to the cross-section of the penumbra shielding area formed by the shielding component.
[0104] There is a gap between the bottom plate 122 and the flat-shaped housing 21, and this gap is located within the full-shadow shielding area 801. Therefore, by providing a sealing housing 40 between the bottom plate 122 of the second cylindrical bracket 12 and the flat-shaped housing 21 to enclose the gap between the two into the first sealing cavity, it is possible to avoid the situation where residual bacteria may exist in the gap between the two due to the shielding block 80 weakening the irradiated rays, thereby contaminating other areas of the detector.
[0105] Furthermore, in this embodiment, the detector further includes a sealing structure located on the side of the shielding assembly away from the first sealing cavity. The sealing structure has a second sealing cavity 44 for enclosing at least part of the full-shadow shielding area 801.
[0106] By enclosing at least part of the full-shadow shielding area 801 with the second sealing cavity 44, the bacteria that may remain in the full-shadow shielding area 801 are isolated from other areas of the detector, thereby avoiding the situation where the sterilization intensity of the full-shadow shielding area 801 is insufficient due to the shielding block 80 weakening the irradiated rays, and further contaminating other areas of the detector.
[0107] Furthermore, the detector further includes a packaging assembly including a first outer shell 51 and a second outer shell 52, and the first outer shell 51 and the second outer shell 52 are coupled to each other to enclose the housing assembly;
[0108] The sealing structure includes a first bracket 41 and a second bracket 42. The first bracket 41 is fixed to the flat-shaped housing 21, and the second bracket 42 is fixed to the second outer shell 52;
[0109] Wherein, when the first outer shell 51 and the second outer shell 52 are coupled, the first bracket 41 and the second bracket 42 cooperate to form the second sealing cavity 44.
[0110] When the user unpacks the detector for use, since the second bracket 42 is fixedly connected to the second outer shell 52, the second bracket 42 will be removed together with the second outer shell 52, which can avoid the second bracket 42 interfering with the user's use. However, at this time, the user has unpacked the detector, the second sealing cavity 44 is opened, but the detector has already been in contact with the outside and is in use, so there is no problem of bacteria in the second sealing cavity 44 contaminating other areas of the detector.
[0111] Furthermore, please combine Figures 1 to 6 , refer to Figure 7 , the first bracket 41 is a hollow cylinder, one end of the first bracket 41 is hermetically connected to the flat-shaped housing 21, and the other end of the first bracket 41 is provided with a mating groove 411;
[0112] The second bracket 42 is a hollow cylinder, and one end of the second bracket 42 away from the first bracket 41 is fixedly connected to the second outer shell 52;
[0113] Wherein, when the first outer shell 51 and the second outer shell 52 are coupled, one end of the second bracket 42 away from the second outer shell 52 is embedded in the mating groove 411 to form the second sealing cavity 44 with the first bracket 41.
[0114] Specifically, the material of the first bracket 41 can be a soft material, including but not limited to silica gel, TPU, rubber, plastic, etc. The soft material first bracket 41 can be more tightly sealed and connected to the second bracket 42 to ensure the tightness of the connection between the two.
[0115] Optionally, in this embodiment, the first outer shell 51 and the second outer shell 52 are threadedly connected.
[0116] The threaded connection between the first outer shell 51 and the second outer shell 52 can, on the one hand, make the detector fit more tightly with the packaging component, thus avoiding accidental opening caused by shaking during transportation; on the other hand, during the process of installing the detector into the packaging component, since the second bracket 42 is fixed to the second outer shell 52, during the process of tightening the first outer shell 51 and the second outer shell 52, a pre-tightening force can be provided to the sealing bracket, enabling the second bracket 42 to be closer to the first bracket 41, making the second bracket 42 fit more tightly with the first bracket 41, thereby ensuring the tightness of the sealing bracket.
[0117] Furthermore, the detector further includes a shielding block placement structure for detachably placing the shielding block 80;
[0118] Wherein, when the shielding block 80 is placed in the shielding block placement structure, the shielding block 80 is used to block the irradiation rays from hitting the sensitive element 221.
[0119] When irradiating for sterilizing the detector, place the shielding block 80 in the shielding block placement structure of the detector to further protect the sensitive element 221 from the influence of irradiation.
[0120] In other alternative embodiments, as Figure 9 shown, the detector further includes a packaging component, the packaging component includes a first outer shell 51 and a second outer shell 52, and the first outer shell 51 and the second outer shell 52 are coupled to each other to wrap the housing assembly;
[0121] The detector further includes a sealing structure located on the side of the flat housing 21 away from the shielding assembly; the sealing structure has a second sealing cavity for wrapping at least a part of the full-shadow shielding area. The sealing structure includes a first bracket 41 fixed to the flat housing 21 and a second bracket 42 fixed to the second outer housing 52.
[0122] The sealing structure further includes a partition plate 45 disposed within the second bracket 42 and sealingly connected to the inner wall of the second bracket 42.
[0123] A through hole is formed in the second outer housing 52 and is correspondingly disposed with the second bracket 42.
[0124] Wherein, the second bracket 42 and the partition plate 45 form the shielding block placement structure; when the shielding block 80 is placed in the shielding block placement structure, the shielding block 80 forms a full-shadow shielding area including the sensitive element.
[0125] The shielding block 80 is placed into the second bracket 42 through the through hole, and the shielding block 80 abuts against the partition plate 45 to shield the irradiation rays. The shielding block 80 in the second bracket 42 and the shielding block 80 in the shielding assembly on the other side of the flat housing 21 are oppositely arranged to respectively block the irradiation rays on both sides of the sensitive element 221.
[0126] After irradiation sterilization, the shielding block 80 can be directly taken out from the second bracket 42 through the through hole, and when sterilizing other detectors, it can be installed in other detectors to realize the reuse of the shielding block 80.
[0127] In other alternative embodiments, a through hole is provided on the end face of the first outer housing.

[0132] In another alternative embodiment, as Figure 10As shown, a first convex shell 511 is provided on the first outer shell 51, and a second convex shell 522 is provided on the second outer shell 52.

[0133] Wherein, the outer walls of the first convex shell 511 and the second convex shell 522 are used to form the shielding block placement structure.
[0134] In this embodiment, the corresponding parts of the high-precision electronic components in the detection circuit board 22 protrude from the housing assembly, and part of the detection circuit board 22 is accommodated by the first convex shell 511 and the second convex shell 522. In this embodiment, the shielding block 80 can be arranged at the upper end of the first convex shell 511 and the lower end of the second convex shell 522, as well as on the sides of the first convex shell 511 and the second convex shell 522, so that the shielding block 80 blocks the irradiation rays generated during the irradiation sterilization process.
[0135] In another alternative embodiment, as Figure 11 shown, the waist of the packaging assembly is recessed inward to form a third recess 54, and the third recess 54 is correspondingly arranged with the flat shell 21;
[0136] Wherein, the third recess 54 is used to form the shielding block placement structure.
[0137] The shielding block 80 is arranged in the third recess 54 at the waist of the flat shell 21, so that the shielding block 80 is located on the path of the irradiation rays shooting at the sensitive element 211, thereby reducing the situation that the irradiation rays shoot at the side of the sensitive element 221 and cause the failure of the sensitive element 221.
[0138] In another alternative embodiment, as Figure 12 shown, the waist of the packaging assembly is recessed inward to form an annular groove 55, and the annular groove 55 is correspondingly arranged with the flat shell 21;
[0139] Wherein, the annular groove 55 is used to form the shielding block placement structure.
[0140] The shielding block 80 is arranged in the annular groove 55 at the waist of the flat shell 21, which can block the irradiation rays shooting from any side end of the sensitive element 221, so that the shielding block 80 is located on the path of the irradiation rays shooting at the sensitive element 211, thereby reducing the influence of the irradiation rays on the sensitive element 221.
[0141] In an alternative embodiment, the guiding needle 25 is fixedly connected to the support bracket 13, and one end of the guiding needle 25 passes through the detection assembly;
[0142] The detector further includes a needle sleeve for accommodating the guiding needle 25, and one end of the needle sleeve is hermetically connected to the flat housing 21.
[0143] The inside of the needle sleeve is sterilized by irradiated rays throughout the process, and there will be no bacteria. The guiding needle 25 is accommodated in the needle sleeve to isolate the guiding needle 25 from other spaces of the detector, so as to avoid the situation that the sterilization intensity is insufficient due to the shielding block 80 blocking the irradiated rays, and then the guiding needle 25 is contaminated by the remaining bacteria.
[0144] In other alternative embodiments, the other end of the needle sleeve is fixedly connected to the second housing 52.
[0145] In other alternative embodiments, the detector further includes a shielding sheet disposed in the flat housing, the shielding sheet is located on the path of the irradiated rays towards the sensitive element, and forms a penumbra shielding area that wraps the sensitive element.
[0146] Specifically, the shielding sheet may be located above the sensitive element 221 to form a penumbra shielding area covering the sensitive element 221.
[0147] Please combine Figures 1 to 12 , refer to Figures 13 to 19 , this application also provides a detector, which includes a housing assembly, a detection assembly, and a shielding assembly; wherein:
[0148] The detection assembly includes a flat housing 21, a detection circuit board 22, and a probe; wherein, the detection circuit board 22 is disposed in the flat housing 21 and is electrically connected to the first end of the probe, the detection circuit board 22 includes a sensitive element 221; the first end of the probe is fixed in the flat housing 21, and the second end of the probe extends out of the flat housing 21.
[0149] The housing assembly includes a contact housing and a pressing part that can slide relative to each other, and the detection assembly is located below the bottom of the pressing part; wherein, the contact housing is used to abut against the sampling part, and the pressing part is used to drive the detection assembly to move towards the sampling part to insert the probe into the sampling part, and the detection signal of the probe is transmitted to the detection circuit board 22.
[0150] The shielding assembly is disposed in the flat housing 21; when the detector is sterilized by irradiated rays, the shielding assembly is used to block part of the irradiated rays to form a penumbra shielding area 801 that protects the sensitive element 221.
[0151] The difference from the above embodiment is that the shielding assembly in the detector in this embodiment is disposed in the flat housing 21.
[0152] When the irradiation rays are emitted from one side of the flat housing 21 towards the sensitive element 221 on the detection circuit board 22, the shielding assembly can block the irradiation rays directed at the sensitive element 221 and form a penumbra shielding area 801 that is not affected by the irradiation rays. By adjusting the position and size of the shielding assembly, the penumbra shielding area 801 formed by the shielding assembly covers the sensitive element 221, weakening or eliminating the irradiation effect of the irradiation rays on the sensitive element 221, thereby alleviating the situation where the sensitive element 221 fails due to the irradiation effect and the detection circuit board 22 cannot work properly. That is, the present application can also protect the detection circuit board 22 from damage while ensuring the sterilization of the detector by the irradiation rays.
[0153] After the electron beam is emitted from the accelerator, it passes through various non-vacuum substances such as air, the outer surface of the sensor, and the housing; these substances will have a strong scattering effect on the electrons, but the electrons cannot penetrate the shielding assembly, and a low-radiation area, that is, a penumbra shielding area, will be formed below the shielding assembly. Due to different electron scattering angles, there is also a radiation dose at the edge of the penumbra shielding area. The irradiation dose is relatively small from the edge of the penumbra shielding area to the center and the area near the shielding assembly in the upper part, and the dose is relatively large the farther away from the shielding assembly. By adjusting the structure and position of the shielding assembly, the area with a relatively small irradiation dose in the penumbra shielding area formed by the shielding assembly wraps the sensitive element.
[0154] Further, the probe is brought into the sampling site through the guiding needle 25;
[0155] The abutting housing includes a first cylindrical bracket 11;
[0156] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a support bracket 13, and an elastic member 14;
[0157] A part of the first cylindrical bracket 11 is slidably located within the pressing shell 105, and a protruding portion 112 is provided on the inner wall of the first cylindrical bracket 11;
[0158] The second cylindrical bracket 12 is slidably sleeved within the first cylindrical bracket 11. The second cylindrical bracket 12 includes a cylindrical structure 121 and a bottom plate 122 at its bottom; a guiding hole 1211 is provided axially in the cylindrical structure 121, and a positioning hole 1213 is provided on the path of the guiding hole 1211; a plurality of connecting portions 1221 extend from the outer edge of the bottom plate 122, and the plurality of connecting portions 1221 are fixedly connected to the pressing shell 105;
[0159] The support bracket 13 is located within the cylindrical structure 121, and an elastic abutting portion 131 extends outward from the support bracket 13;
[0160] The elastic member 14 is compressed between the bottom plate 122 and the top of the support bracket 13;
[0161] Wherein, in the initial state, the elastic member 14 is in a compressed state, and the elastic abutting portion 131 is located in the positioning hole 1213;
[0162] Under the action of an external force, the pressing shell 105 drives the second cylindrical bracket 12 to move relative to the first cylindrical bracket 11, so that the convex portion 112 moves along the guiding hole 1211; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a first predetermined position, the guiding needle 25 guides the detection needle to pierce into the sampling site; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a second predetermined position, the convex portion 112 extrudes the elastic abutting portion 131 out of the positioning hole 1213, the elastic member 14 is released, and the guiding needle 25 is driven to leave the sampling site through the support bracket 13.
[0163] In an alternative embodiment, as Figure 13 and Figure 14 , the shielding assembly includes a shielding framework, the shielding framework is fixed to one side of the detection circuit board 22 provided with the sensitive element 221, and the shielding framework is used to block the irradiation rays to form a penumbra shielding area 801 in a specified area.
[0164] When sterilizing the detector, the detector can be placed horizontally, and the position of the detector can be adjusted so that the shielding framework is located on the path of the irradiation rays shooting at the sensitive element 221, so that the penumbra shielding area 801 formed by the shielding framework protects the sensitive element 221 from the influence of the irradiation rays.
[0165] In an alternative embodiment, as Figure 15 shown, the shielding assembly includes a shielding framework, the shielding framework is fixed to the detection circuit board 22, the shielding framework is arranged around the periphery of the sensitive element 221, and the shielding framework is used to block the irradiation rays to form a penumbra shielding area 801 in a specified area.
[0166] When sterilizing the detector, the detector can be placed horizontally. Since the shielding framework is arranged around the periphery of the sensitive element 221, the space inside the shielding framework is a penumbra shielding area 801, which can block the irradiation rays shooting from any direction at the side end of the sensitive element 221 to protect the sensitive element 221 from the influence of the irradiation rays.
[0167] In an alternative embodiment, please refer to Figures 16 to 18 , the detection circuit board 22 is provided with fixing holes 227;
[0168] The shielding component includes a shielding framework, which includes a connecting plate 71 and two side baffles 72. The connecting plate 71 passes through the fixing hole 227, and the two side baffles 72 are respectively fixed to opposite ends of the connecting plate 71 to clamp the sensitive element 221.
[0169] When sterilizing the detector, the detector can be placed under the irradiation source. The sensitive element 221 is located between the two side baffles 72, and the connecting plate 71 is located at one end of the sensitive element 221. Such a structure can block the irradiation rays in at least three directions of the sensitive element 221. The penumbra shielding area 801 formed by the two side baffles 72 and the connecting plate 71 covers the sensitive element 221 to protect the sensitive element 221 from being affected by the irradiation rays.
[0170] Further, as Figure 19 shown, the shielding framework further includes a vertical plate 73. The vertical plate 73 is located on the side of the detection circuit board 22 where the sensitive element 221 is provided, and one end of the vertical plate 73 is fixed to opposite ends of the side baffle 72 located on this side.
[0171] The vertical plate 73 is arranged on the side baffle 72 and extends towards the side close to the detection circuit board 22, so that the connecting plate 71, the two side baffles 72 and the two vertical plates 73 are respectively located in five different directions of the sensitive element 221 and form a penumbra shielding area 801 covering the sensitive element 221, which can better protect the sensitive element 221 from being affected by the irradiation rays.
[0172] Optionally, the shielding framework in the above embodiment can specifically be components in the detection circuit board, such as components like batteries, electromagnetic buckles, etc. that meet the function of shielding irradiation rays.
[0173] Optionally, the material of the shielding framework in the above embodiment is the same as that of the shielding block 80, and both can achieve the function of blocking irradiation rays.
[0174] It can be understood that the shape of the shielding framework is not limited to the above scheme and can be set according to specific requirements. For example, the cross-section of the shielding framework can also be a curved surface, a polygon, etc., as long as the penumbra shielding area formed by the shielding framework can wrap the sensitive element.
[0175] It should be noted that although the shielding framework can block the irradiation rays, it also weakens the sterilization intensity of the irradiation rays on the penumbra shielding area 801. There may be insufficient sterilization intensity and it is impossible to completely sterilize the penumbra shielding area 801, resulting in bacteria still existing in the penumbra shielding area 801 inside the detector after irradiation sterilization, and then contaminating other areas of the detector.
[0176] Based on the above problems, in this embodiment, the detector further includes a sealing shell 40, the sealing shell 40 is located between the bottom plate 122 and the flat shell 21, an outer wall of the sealing shell 40 and the flat shell 21 forms a first sealing cavity (not labeled in the figure), and the first sealing cavity is correspondingly arranged with the shielding component.
[0177] Preferably, a cross-section of the first sealing cavity is greater than or equal to a cross-section of a full-shadow shielding area formed by the shielding component.
[0178] There is a gap between the bottom plate 122 and the flat shell 21, and this gap is located within the full-shadow shielding area 801. Therefore, by arranging the sealing shell 40 between the bottom plate 122 of the second cylindrical bracket 12 and the flat shell 21, the gap between the two is wrapped into the first sealing cavity, thereby avoiding the situation that residual bacteria may exist in the gap between the two due to the weakened irradiation rays of the shielding block 80, and further contaminating other areas of the detector.
[0179] Further, in this embodiment, the detector further includes a sealing structure, the sealing structure is located on a side of the shielding component away from the first sealing cavity, and the sealing structure has a second sealing cavity 44, and the second sealing cavity 44 is used for wrapping at least a part of the full-shadow shielding area 801.
[0180] By wrapping at least a part of the full-shadow shielding area 801 with the second sealing cavity 44, the bacteria that may remain in the full-shadow shielding area 801 are isolated from other areas of the detector, thereby avoiding the situation that due to the weakened irradiation rays of the shielding block 80, the sterilization intensity of the full-shadow shielding area 801 is insufficient, and further contaminating other areas of the detector.
[0181] Further, the detector further includes a packaging component, the packaging component includes a first outer shell 51 and a second outer shell 52, and the first outer shell 51 and the second outer shell 52 are coupled to each other to wrap the housing component;
[0182] The sealing structure includes a first bracket 41 and a second bracket 42, the first bracket 41 is fixed to the flat shell 21, and the second bracket 42 is fixed to the second outer shell 52;
[0183] Wherein, when the first outer shell 51 and the second outer shell 52 are coupled, the first bracket 41 and the second bracket 42 cooperate to form the second sealing cavity 44.
[0184] When the user unpacks the detector for use, since the second bracket 42 is fixedly connected to the second housing 52, the second bracket 42 will be removed together with the second housing 52, which can prevent the second bracket 42 from interfering with the user's operation. At this time, the user has unpacked the detector and the second sealing cavity 44 is opened. However, since the detector has been in contact with the outside and is in use, there is no problem of bacteria in the second sealing cavity 44 contaminating other areas of the detector.
[0185] Further, please refer to Figures 1 to 6 and Figure 7 The first bracket 41 is a hollow cylinder. One end of the first bracket 41 is hermetically connected to the flat housing 21, and the other end of the first bracket 41 is provided with a mating groove 411.
[0186] The second bracket 42 is a hollow cylinder. The end of the second bracket 42 away from the first bracket 41 is fixedly connected to the second housing 52.
[0187] Wherein, when the first housing 51 and the second housing 52 are coupled, the end of the second bracket 42 away from the second housing 52 is inserted into the mating groove 411 to form the second sealing cavity 44 with the first bracket 41.
[0188] Specifically, the material of the first bracket 41 can be a soft material, including but not limited to silicone, TPU, rubber, plastic, etc. The soft material first bracket 41 can be more tightly sealed to the second bracket 42 to ensure the tightness of their connection.
[0189] Optionally, in this embodiment, the first housing 51 and the second housing 52 are threadedly connected.
[0190] The threaded connection between the first housing 51 and the second housing 52 can, on the one hand, make the detector fit more tightly with the packaging component, thus avoiding accidental unpacking caused by shaking during transportation. On the other hand, during the process of installing the detector into the packaging component, since the second bracket 42 is fixed to the second housing 52, during the process of tightening the first housing 51 and the second housing 52, a pre-tightening force can be provided to the sealing bracket, which can make the second bracket 42 closer to the first bracket 41, so that the second bracket 42 fits more tightly with the first bracket 41, thereby ensuring the tightness of the sealing bracket.
[0191] Please refer to Figures 1 to 19 and Figures 20 to 24 An embodiment of the present application further provides a sterilization system, which includes a carrier frame 91 for cooperating with an irradiation source 98 for sterilization.
[0192] The carrier frame 91 is located on one side of the irradiation source 98. A plurality of carrier slots are provided on the side of the carrier frame 91 facing the irradiation source 98, and each carrier slot can hold a detector as described in any one of claims 1-15.
[0193] Wherein, when the detector is placed in the carrier slot, the carrier slot is used to correct the orientation of the detector so that the shielding component in the detector is located on the path of the irradiation from the irradiation source 98 to the detector.
[0194] The irradiation source 98 can emit various types of irradiation rays, including but not limited to X-rays, electron beams, and gamma rays.
[0195] When irradiating and sterilizing multiple detectors at one time, multiple detectors can be placed in different carrier slots in the carrier frame 91. Since the rays emitted by the irradiation source 98 are in multiple directions, in order to ensure that each detector can be directly irradiated by the irradiation rays, in this embodiment, the orientation of the detectors located therein is corrected by the carrier frame 91 to ensure that the shielding component or the shielding block 80 can correctly achieve the shielding effect, that is, form a penumbra shielding area 801 that wraps the sensitive element 221 and is not involved in the irradiation rays.
[0196] Further, in this embodiment, the center of the carrier frame 91 is correspondingly arranged with the irradiation source 98;
[0197] The carrier slots in the middle of the carrier frame 91 are vertically arranged, and the other carrier slots adjacent to the middle carrier slot are inclined toward the side pointing to the irradiation source 98;
[0198] Wherein, the farther the carrier slot is from the irradiation source 98, the greater its inclination angle.
[0199] Specifically, the carrier slot in the middle of the carrier frame 91 is directly opposite to the irradiation source 98, and the angle formed by the irradiation rays emitted by the irradiation source 98 and the surface of the carrier frame 91 is a right angle, so this carrier slot is vertically arranged. The farther away from the irradiation source 98, the smaller the angle formed by the irradiation rays emitted by the irradiation source 98 and the surface of the carrier frame 91. Relatively adjust the inclination angle of the carrier slot so that the central axes of all carrier slots can point to the irradiation source 98 to ensure that the shielding component or the shielding block 80 can correctly achieve the shielding effect, that is, form a penumbra shielding area 801 that wraps the sensitive element 221 and is not involved in the irradiation rays.
[0200] Specifically, according to the formation method and position of the penumbra shielding area, the detectors can be placed in the carrier frame 91 in a substantially vertical manner or in a substantially horizontal manner.
