[0002] In conventional medical testing environments, when it is necessary to perform subcutaneous sampling tests on the subject to be tested, a detector is required.

[0091] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0092] See also Figures 1 to 24 An embodiment of the present application provides a detector, which includes a shell component, a detection component, and a shielding component; a detailed description is given below.

[0093] The detection assembly includes a flat shell 21, a detection circuit board 22, and a probe (not shown); wherein the detection circuit board 22 is disposed in the flat shell 21 and is 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 shell 21, and the second end of the probe extends out of the flat shell 21;

[0094] The housing assembly includes a relatively slidable abutment housing and a pressing portion, and the detection assembly is located below the bottom of the pressing portion; wherein the abutment housing is used to abut against the sampling portion, and the pressing portion is used to drive the detection assembly to move toward the sampling portion so as to insert the probe into the sampling portion, and the detection signal of the probe is transmitted to the detection circuit board 22;

[0095] The shielding component is disposed on a side surface of the flat shell 21 ; when the detector is sterilized by radiation, the shielding component is used to block part of the radiation to form a full-shadow shielding area 801 to protect the sensitive element 221 .

[0096] The sensitive element 221 is a high-precision electronic component that is easily affected by radiation and may fail.

[0097] Radiation includes, but is not limited to, X-rays, electron beams, and gamma rays.

[0098] When the radiation rays are directed from one side of the flat shell 21 to the sensitive element 221 on the detection circuit board 22, the shielding component can block the radiation rays directed to the sensitive element 221 and form a full-shadow shielding area 801 that is not affected by the radiation rays. The position and size of the shielding component are adjusted so that the full-shadow shielding area 801 formed by the shielding component covers the sensitive element 221, weakening or eliminating the radiation effect on the sensitive element 221, thereby alleviating the situation where the sensitive element 221 is affected by the radiation and fails, causing the detection circuit board 22 to not work properly. That is, the present application can protect the detection circuit board 22 from damage while ensuring that the radiation rays sterilize the detector.

[0099] In this embodiment, when the detector is sterilized, the detector can be placed under the radiation source so that the full-shadow shielding area 801 formed by the shielding component wraps around the sensitive element 221.

[0100] Specifically, the cross-section of the full-shadow shielding area 801 formed by the shielding assembly is a triangle or a polygon.

[0101] See also Figures 1 to 6 In an optional embodiment, the probe is brought into the sampling site via a guide needle 25;

[0102] The abutment housing comprises a first cylindrical support 11;

[0103] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a supporting bracket 13 and an elastic member 14;

[0104] 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;

[0105] 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;

[0106] The support bracket 13 is located in the cylindrical structure 121, and the support bracket 13 has an elastic abutment portion 131 extending outward;

[0107] The elastic member 14 is compressed between the bottom plate 122 and the top of the supporting bracket 13;

[0108] 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;

[0109] 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.

[0110] In this embodiment, the elastic member 14 may 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 exerts an elastic force on the second cylindrical bracket 12 and the support bracket 13 to move away from each other, but since the elastic abutting portion 131 is located in the positioning hole 1213, the elastic force generated by the elastic member 14 pushes 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.

[0111] Specifically, the detector can be used to detect a variety of body index data. The following embodiments take blood sugar detection as an example.

[0112] When the user uses the detector to test blood sugar, the user holds the pressing shell 105 and aligns it with the sampling site, so that one end of the contact shell is against the sampling site. At this time, the guide needle 25 does not contact the sampling site, and then pushes the pressing shell 105 to move toward 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 is against the second cylindrical bracket 12 through the elastic abutment portion 131, the pressing shell 105 can further drive the support bracket 13 and the detection component to move toward the side close to the sampling site when driving the second cylindrical bracket 12 to move. In the process of the second cylindrical bracket 12 driving the detection component to move, the guide 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 guide needle 25 pierces the sampling site. The probe follows the guide needle 25 to pierce, so that sampling is performed through the probe, and the probe transmits data to the detection circuit board 22 to detect blood sugar indicators.

[0113] The user continues to push the pressing shell 105 toward the side close to the sampling site until the second cylindrical bracket 12 reaches the second predetermined position. At this time, the protrusion 112 squeezes the elastic abutment portion 131 out of the positioning hole 1213, and the elastic abutment portion 131 no longer abuts against the hole wall of the positioning hole 1213, and 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 toward the side away from the sampling site, thereby driving the guide needle 25 to leave the sampling site, so as to quickly pull out the guide 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 guide needle 25, but will remain in the sampling site, so as to enable continuous sampling and detection, thereby dynamically feeding back the detection results.

[0114] Through the structure of the above-mentioned detector, the user can push the pressing shell 105 and insert the probe into the sampling site through the guide needle 25. After the guide needle 25 brings the probe into the sampling site to a certain depth, the support bracket 13 is no longer limited by the second cylindrical bracket 12, and the spring is released to quickly pull the guide needle 25 out of the sampling site along the insertion path. It is not easy to deviate from the trajectory, withdraw the needle slowly, etc., which may cause severe pain to the person to be tested, damage the skin, etc., thereby improving the experience of the person to be tested.

[0115] Further, in this embodiment, the shielding assembly includes a shielding block fixing structure 31 and a shielding block 80;

[0116] 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 ;

[0117] The shielding block 80 is detachably received in the shielding block receiving groove 311 to block the radiation to form a full-shadow shielding area 801 of a designated area.

[0118] It can be understood that after the radiation sterilization of the detector is completed, the shielding block 80 can be taken out from the shielding block receiving slot 311, or it can be retained in the detector.

[0119] Specifically, the shielding block 80 is a rectangular parallelepiped structure. The density of the shielding block 80 is greater than 1000 kilograms per cubic meter. 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 radiation.

[0120] It should be noted that although the shielding block 80 can block the radiation rays, it also weakens the sterilization intensity of the radiation rays on the full-shadow shielding area 801. The sterilization intensity may be insufficient and the full-shadow shielding area 801 cannot be completely sterilized, resulting in the presence of bacteria in the full-shadow shielding area 801 in the detector after radiation sterilization, thereby contaminating other areas of the detector.

[0121] Based on the above problems, in this embodiment, the detector also includes a sealing shell 40, which is located between the base plate 122 and the flat shell 21, and the outer wall of the sealing shell 40 and the flat shell 21 forms a first sealed cavity (not marked in the figure), and the first sealed cavity is arranged corresponding to the shielding assembly.

[0122] Preferably, the cross-section of the first sealed cavity is greater than or equal to the cross-section of the full-shadow shielding area formed by the shielding assembly.

[0123] There is a gap between the bottom plate 122 and the flat shell 21, and the gap is located in the full-shadow shielding area 801. Therefore, a sealing shell 40 is set between the bottom plate 122 of the second cylindrical bracket 12 and the flat shell 21 to wrap the gap between the two into the first sealed cavity, thereby avoiding the situation where residual bacteria may exist in the gap between the two due to the shielding block 80 weakening the radiation, thereby contaminating other areas of the detector.

[0124] Furthermore, in this embodiment, the detector also includes a sealing structure, which is located on a side of the shielding component away from the first sealing cavity. The sealing structure has a second sealing cavity 44, and the second sealing cavity 44 is used to wrap at least part of the full-shadow shielding area 801.

[0125] At least a portion of the full-shadow shielding area 801 is wrapped by the second sealed cavity 44 to isolate bacteria that may remain in the full-shadow shielding area 801 from other areas of the detector, thereby avoiding the situation where the shielding block 80 weakens the radiation, resulting in insufficient sterilization intensity in the full-shadow shielding area 801, thereby contaminating other areas of the detector.

[0126] Furthermore, the detector further comprises a packaging assembly, wherein the packaging assembly comprises a first shell 51 and a second shell 52, wherein the first shell 51 and the second shell 52 are coupled to each other to wrap the housing assembly;

[0127] The sealing structure includes a first bracket 41 and a second bracket 42, wherein the first bracket 41 is fixed to the flat shell 21, and the second bracket 42 is fixed to the second shell 52;

[0128] In which, when the first shell 51 and the second shell 52 are coupled, the first bracket 41 and the second bracket 42 cooperate to form the second sealed cavity 44 .

[0129] 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, so that the second bracket 42 can be prevented from interfering with the user's use. Although the user has already unpacked the detector and opened the second sealed cavity 44, the detector has been exposed to the outside world and used, so there is no problem of bacteria in the second sealed cavity 44 contaminating other areas of the detector.

[0130] Furthermore, please combine Figures 1 to 6 , see Figure 7 The first bracket 41 is a hollow cylinder, one end of the first bracket 41 is sealed and connected to the flat shell 21, and the other end of the first bracket 41 is provided with a matching groove 411;

[0131] 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 shell 52;

[0132] In which, when the first housing 51 and the second housing 52 are coupled, one end of the second bracket 42 away from the second housing 52 is embedded in the matching groove 411 to form the second sealed cavity 44 with the first bracket 41 .

[0133] Specifically, the material of the first bracket 41 may be a soft material, including but not limited to silicone, TPU, rubber, plastic, etc. The first bracket 41 made of soft material can be more tightly sealed and connected with the second bracket 42 to ensure the sealing of the connection between the two.

[0134] Optionally, in this embodiment, the first shell 51 and the second shell 52 are threadedly connected.

[0135] The first shell 51 and the second shell 52 are threadedly connected. On the one hand, this can make the detector fit more closely to the packaging assembly, thereby avoiding accidental opening due to shaking during transportation; on the other hand, in the process of installing the detector into the packaging assembly, since the second bracket 42 is fixed to the second shell 52, in the process of tightening the first shell 51 and the second shell 52, a pre-tightening force can be provided to the sealing bracket, so that the second bracket 42 can be closer to the first bracket 41, so that the second bracket 42 and the first bracket 41 fit more closely, thereby ensuring the sealing of the sealing bracket.

[0136] Furthermore, the detector further comprises a shielding block placement structure, and the shielding block placement structure is used to detachably place the shielding block 80;

[0137] Wherein, when the shielding block 80 is placed in the shielding block placement structure, the shielding block 80 is used to block the radiation rays from being directed toward the sensitive element 221 .

[0138] When the detector is sterilized by irradiation, the shielding block 80 is placed in the shielding block placement structure of the detector to further protect the sensitive element 221 from the influence of the irradiation.

[0139] In other optional embodiments, Fig. 9 As shown, the detector further includes a packaging assembly, and the packaging assembly includes a first shell 51 and a second shell 52, and the first shell 51 and the second shell 52 are coupled to each other to wrap the housing assembly;

[0140] The detector further comprises a sealing structure, which is located at a side of the flat shell 21 away from the shielding assembly; the sealing structure has a second sealing cavity, which is used to wrap at least a portion of the full-shadow shielding area, and the sealing structure comprises a first bracket 41 and a second bracket 42, wherein the first bracket 41 is fixed to the flat shell 21, and the second bracket 42 is fixed to the second shell 52;

[0141] The sealing structure further includes an isolation plate 45, which is disposed in the second bracket 42, and the isolation plate 45 is sealed and connected to the inner wall of the second bracket 42;

[0142] The second housing 52 is provided with a through hole, and the through hole is arranged corresponding to the second bracket 42;

[0143] The second bracket 42 and the isolation 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 sensitive elements.

[0144] The shielding block 80 is placed into the second bracket 42 through the through hole, and the shielding block 80 is placed against the isolation plate 45 to shield the radiation. 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 shell 21 are arranged opposite to each other to block the radiation on both sides of the sensitive element 221.

[0145] After irradiation sterilization, the shielding block 80 can be directly taken out from the second bracket 42 through the via hole, so that it can be installed in other detectors when other detectors are sterilized, so as to realize the reuse of the shielding block 80.

[0146] In other optional embodiments, the end surface of the first housing is provided with a through hole;

[0147] The end surface of the second shell is recessed inwardly to form a first recessed portion;

[0148] Correspondingly, the end surface of the housing component close to the first shell is recessed inward to form a second recessed portion;

[0149] Wherein, the through hole, the first recessed portion, and the second recessed portion are correspondingly arranged and combined to form the shielding block placement structure.

[0150] When the shielding block is placed in the shielding block placement structure, the shielding block is located on two opposite sides of the sensitive element to form a full-shadow shielding area that wraps the sensitive element.

[0151] In another alternative embodiment, if Fig.10 As shown, the first housing 51 is provided with a first convex shell 511, and the second housing 52 is provided with a second convex shell 522. The first convex shell 511 and the second convex shell 522 cooperate to form a convex cavity (not marked in the figure), and the convex cavity is used to accommodate the sensitive element 221 of the detection circuit board 22 in the flat housing 21;

[0152] The outer wall of the first convex shell 511 and the outer wall of the second convex shell 522 are used to form the shielding block placement structure.

[0153] In this embodiment, the corresponding parts of the high-precision electronic components in the detection circuit board 22 protrude from the housing assembly, and the first convex shell 511 and the second convex shell 522 are used to accommodate part of the detection circuit board 22. 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 the sides of the first convex shell 511 and the second convex shell 522, so that the shielding block 80 blocks the radiation generated during the radiation sterilization process.

[0154] In another alternative embodiment, if Fig.11 As shown, the waist of the packaging assembly is recessed inward to form a third recessed portion 54, and the third recessed portion 54 is disposed corresponding to the flat shell 21;

[0155] The third recessed portion 54 is used to form the shielding block placement structure.

[0156] The shielding block 80 is disposed in the third recessed portion 54 at the waist of the flat shell 21 so that the shielding block 80 is located on the path of the radiation rays directed toward the sensitive element 211, thereby reducing the situation where the radiation rays are directed toward the side of the sensitive element 221 and cause the sensitive element 221 to malfunction.

[0157] In another alternative embodiment, if Fig.12 As shown, the waist of the packaging component is recessed inward to form an annular groove 55, and the annular groove 55 is arranged corresponding to the flat shell 21;

[0158] The annular groove 55 is used to form the shielding block placement structure.

[0159] Setting the shielding block 80 in the annular groove 55 at the waist of the flat shell 21 can block the radiation emitted from any side end of the sensitive element 221, so that the shielding block 80 is located on the path of the radiation emitted to the sensitive element 211, thereby reducing the impact of the radiation on the sensitive element 221.

[0160] In an optional embodiment, the guide needle 25 is fixedly connected to the support bracket 13, and one end of the guide needle 25 passes through the detection component;

[0161] The detector further comprises a needle sleeve, which is used to accommodate the guide needle 25 , and one end of the needle sleeve is sealedly connected to the flat housing 21 .

[0162] The inside of the needle sleeve will be sterilized by the radiation, and no bacteria will be present. The guide needle 25 is accommodated in the needle sleeve, so that the guide needle 25 is isolated from other spaces of the detector, so as to avoid the shielding block 80 blocking the radiation and causing insufficient sterilization strength, thereby causing the guide needle 25 to be contaminated by residual bacteria.

[0163] In other optional embodiments, the other end of the needle sleeve is fixedly connected to the second shell 52.

[0164] In other optional embodiments, the detector further includes a shielding plate, which is disposed in the flat shell, is located on the path of the radiation rays directed toward the sensitive element, and forms a full-shadow shielding area that wraps the sensitive element.

[0165] Specifically, the shielding sheet may be located above the sensitive element 221 to form a full-shadow shielding area covering the sensitive element 221 .

[0166] Please combine Figures 1 to 12 , see Figures 13 to 19 The present application also provides a detector, which includes a housing component, a detection component, and a shielding component; wherein:

[0167] The detection assembly includes a flat shell 21, a detection circuit board 22, and a probe; wherein the detection circuit board 22 is disposed in the flat shell 21 and is 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 shell 21, and the second end of the probe extends out of the flat shell 21;

[0168] The housing assembly includes a relatively slidable abutment housing and a pressing portion, and the detection assembly is located below the bottom of the pressing portion; wherein the abutment housing is used to abut against the sampling portion, and the pressing portion is used to drive the detection assembly to move toward the sampling portion so as to insert the probe into the sampling portion, and the detection signal of the probe is transmitted to the detection circuit board 22;

[0169] The shielding component is disposed in the flat shell 21 ; when the detector is sterilized by radiation, the shielding component is used to block part of the radiation to form a full-shadow shielding area 801 to protect the sensitive element 221 .

[0170] The difference from the above embodiment is that the shielding component in the detector in this embodiment is arranged in a flat housing 21 .

[0171] When the radiation rays are directed from one side of the flat shell 21 to the sensitive element 221 on the detection circuit board 22, the shielding component can block the radiation rays directed to the sensitive element 221 and form a full-shadow shielding area 801 that is not affected by the radiation rays. The position and size of the shielding component are adjusted so that the full-shadow shielding area 801 formed by the shielding component covers the sensitive element 221, weakening or eliminating the radiation effect on the sensitive element 221, thereby alleviating the situation where the sensitive element 221 is affected by the radiation and fails, causing the detection circuit board 22 to not work properly. That is, the present application can protect the detection circuit board 22 from damage while ensuring that the radiation rays sterilize the detector.

[0172] After being emitted from the accelerator, the electron beam passes through the air, the outer surface of the sensor, the outer shell and other non-vacuum materials; these materials will form a very strong scattering effect on the electrons, but the electrons cannot penetrate the shielding component, and a low radiation area will be formed below the shielding component, that is, the full-shadow shielding area. Due to the different electron scattering angles, there is also a radiation dose at the edge of the full-shadow shielding area. The radiation dose from the edge of the full-shadow shielding area to the center and the upper area close to the shielding component is relatively small, and the dose farther away from the shielding component is relatively large. By adjusting the structure and position of the shielding component, the relatively small radiation dose area in the full-shadow shielding area formed by the shielding component wraps the sensitive element.

[0173] Further, the probe is brought into the sampling site through the guide needle 25;

[0174] The abutment housing comprises a first cylindrical support 11;

[0175] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a supporting bracket 13 and an elastic member 14;

[0176] 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;

[0177] 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;

[0178] The support bracket 13 is located in the cylindrical structure 121, and the support bracket 13 has an elastic abutment portion 131 extending outward;

[0179] The elastic member 14 is compressed between the bottom plate 122 and the top of the supporting bracket 13;

[0180] 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;

[0181] 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.

[0182] In an alternative embodiment, if Fig.13 and Fig.14 The shielding assembly includes a shielding frame, which is fixed to a side of the detection circuit board 22 where the sensitive element 221 is provided. The shielding frame is used to block the radiation to form a full-shadow shielding area 801 in a designated area.

[0183] When sterilizing the detector, the detector can be placed horizontally and the position of the detector can be adjusted so that the shielding frame is located on the path of the radiation to the sensitive element 221, so that the full shadow shielding area 801 formed by the shielding frame protects the sensitive element 221 from the radiation.

[0184] In an alternative embodiment, if Fig.15 As shown, the shielding assembly includes a shielding frame, which is fixed to the detection circuit board 22 and arranged around the periphery of the sensitive element 221 , and is used to block the radiation to form a full-shadow shielding zone 801 of a designated area.

[0185] When sterilizing the detector, the detector can be placed horizontally. Since the shielding frame is arranged around the periphery of the sensitive element 221, the space within the shielding frame is a full-shadow shielding area 801, which can block the radiation rays from any direction of the side end of the sensitive element 221 to protect the sensitive element 221 from being affected by the radiation rays.

[0186] In an alternative embodiment, see Figures 16 to 18 , the detection circuit board 22 is provided with a fixing hole 227;

[0187] The shielding assembly includes a shielding frame, and the shielding frame includes a connecting plate 71 and two side baffles 72 . The connecting plate 71 is inserted into 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 .

[0188] When sterilizing the detector, the detector can be placed under the radiation 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 at least block the radiation rays from three directions of the sensitive element 221. The full-shadow 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 radiation rays.

[0189] Furthermore, if Fig.19 As shown, the shielding frame further includes a vertical plate 73, which is located on a 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 the side.

[0190] The vertical plate 73 is arranged on the side baffle plate 72 and extends toward the side close to the detection circuit board 22, so that the connecting plate 71, the two side baffle plates 72 and the two vertical plates 73 are respectively located in five different directions of the sensitive element 221 and form a full shadow shielding area 801 covering the sensitive element 221, which can better protect the sensitive element 221 from the influence of radiation.

[0191] Optionally, the shielding structure in the above embodiment may specifically be a component in the detection circuit board, such as a battery, an electromagnetic buckle, or other component that satisfies the function of shielding radiation.

[0192] Optionally, the material of the shielding frame in the above embodiment is the same as that of the shielding block 80, and both can achieve the function of blocking radiation.

[0193] It is understandable that the shape of the shielding structure is not limited to the above solution and can be set according to specific needs. For example, the cross-section of the shielding structure can also be a curved surface, a polygon, etc., as long as the full-shadow shielding area formed by the shielding structure can wrap the sensitive components.

[0194] Please combine Figures 1 to 19 , see Figure 20 to Figure 24 , the embodiment of the present application further provides a sterilization system, the sterilization system includes a carrying frame 91, the carrying frame 91 is used to cooperate with the radiation source 98 for sterilization;

[0195] The carrying frame 91 is located at one side of the radiation source 98 , and a plurality of carrying slots are provided on the side of the carrying frame 91 facing the radiation source 98 , each of which can hold a detector as described in any one of claims 1 to 15 .

[0196] When the detector is placed in the carrying slot, the carrying 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 radiation source 98 irradiating the detector.

[0197] The radiation source 98 can emit various types of radiation, including but not limited to X-rays, electron beams, and gamma rays.

[0198] When multiple detectors are sterilized by irradiation at one time, the multiple detectors can be placed in different bearing slots in the bearing frame 91. Since the radiation source 98 emits rays in multiple directions, in order to ensure that each detector can be directly irradiated with radiation, in this embodiment, the bearing frame 91 is used to correct the orientation of the detectors therein, so as to ensure that the shielding assembly or shielding block 80 can correctly achieve the shielding effect, that is, to form a full-shadow shielding area 801 that wraps the sensitive element 221 and is not affected by the radiation.

[0199] Further, in this embodiment, the center of the carrying frame 91 is arranged corresponding to the radiation source 98;

[0200] The bearing slot in the middle of the bearing frame 91 is vertically arranged, and the other bearing slots adjacent to the middle bearing slot are inclined toward the side pointing to the radiation source 98;

[0201] The farther the bearing slot is from the radiation source 98 , the greater its inclination angle is.

[0202] Specifically, the bearing slot in the middle of the bearing frame 91 is directly opposite to the radiation source 98, and the angle between the radiation rays emitted by the radiation source 98 and the surface of the bearing frame 91 is a right angle, so the bearing slot is vertically arranged. The farther away from the radiation source 98, the smaller the angle between the radiation rays emitted by the radiation source 98 and the surface of the bearing frame 91. The inclination angle of the bearing slot is adjusted relatively so that the central axis of all the bearing slots can point to the radiation source 98, so as to ensure that the shielding assembly or the shielding block 80 can correctly achieve the shielding effect, that is, to form a full shadow shielding area 801 that wraps the sensitive element 221 and will not be affected by the radiation rays.

[0203] The placement of the detector is adjusted specifically according to the formation method and position of the full-shadow shielding area. The detector can be placed in the carrying frame 91 in a basically vertical manner, or in a basically horizontal manner.
