[0054] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0055] Please see Figures 1 to 11 This application provides a detector, which includes a housing assembly, a detection assembly, and a shielding block placement structure, which will be described in detail below.

[0056] The detection assembly includes a probe, a detection circuit board 43, and a flat housing 44, wherein the detection circuit board 43 is at least partially located within the shielding area of ​​the flat housing 44.

[0057] The housing assembly is used to move the detection assembly closer to the sampling site so that the probe can be inserted into the sampling site.

[0058] The shielding block placement structure is located outside the shielding area of ​​the flat shell 44 and is used to place the shielding block 60.

[0059] When the shielding block 60 is placed in the shielding block placement structure, the shielding block 60 is used to block radiation rays from hitting the shielded area.

[0060] It should be noted that the detection circuit board 43 contains some high-precision electronic components that are easily affected by radiation. The shielding area can include the area on the detection circuit board 43 where these high-precision electronic components are placed.

[0061] In this embodiment, the irradiation radiation includes, but is not limited to, X-rays, electron beams, and gamma rays.

[0062] Specifically, the detector can be used to detect a variety of physical indicators. The following example uses blood glucose testing as an example.

[0063] When the detector is sterilized by irradiation, to prevent the irradiation from affecting the detection circuit board 43, a shielding block 60 can be placed in the detector's shielding block placement structure to block the shielding area of ​​the flat housing 44. That is, the shielding block 60 blocks the path of the irradiation rays towards the detection circuit board 43, reducing or eliminating the irradiation effect on the detection circuit board 43. This mitigates the possibility of the detection circuit board 43 malfunctioning due to irradiation and thus ensuring its accuracy. In other words, this application can protect the detection circuit board 43 from damage while ensuring the sterilization of the detector by irradiation.

[0064] In an optional embodiment, the detector further includes a packaging assembly, wherein the packaging assembly includes an upper packaging shell 31 and a lower packaging shell 32.

[0065] The end face of the upper packaging shell 31 is provided with a through hole 311;

[0066] The end face of the lower packaging shell 32 is recessed inward to form a first recessed portion 321;

[0067] Correspondingly, the end face of the housing assembly that is close to the upper packaging shell 31 is recessed inward to form a second recess 2105;

[0068] The via 311, the first recess 321, and the second recess 2105 are respectively provided and combined to form the shielding block placement structure.

[0069] The shielding block 60 can be inserted into the first recess 321 through the through-hole 311, or it can be inserted into the second recess 2105. When the shielding block 60 is placed in the first recess 321 and the second recess 2105, the radiation rays can be controlled to exit from the top or bottom of the detector to sterilize the detector, so that the shielding block 60 blocks the radiation rays in the corresponding direction, reducing or eliminating the influence of the radiation rays on the detection circuit board 43. After the irradiation sterilization, the shielding block 60 can be directly removed from the first recess 321 and the second recess 2105 to achieve reuse of the shielding block 60.

[0070] In some embodiments, the shielding block is removably disposed in the shielding block placement structure.

[0071] It should be noted that although the shielding block 60 can block the radiation, it also weakens the sterilization intensity of the radiation on the shielded area. This may result in insufficient sterilization intensity, which may not be able to completely sterilize the shielded area. Consequently, bacteria may still exist in the shielded area of ​​the detector after irradiation sterilization, thus contaminating other areas of the detector.

[0072] Based on the above problems, in this embodiment, the detector further includes a sealing bracket 50, which forms a sealing cavity 55 with the flat shell 44. The sealing cavity 55 is correspondingly arranged (enclosing or covering) the shielding area, and the sealing cavity 55 is isolated from other spaces of the detector.

[0073] The sealing bracket 50 includes a first bracket 51 and a second bracket 52, wherein the first bracket 51 is fixed to the first recess 321 and the second bracket 52 is fixed to the first recess 321.

[0074] The sealing bracket 50 and the flat shell 44 form a sealing cavity 55 to isolate bacteria that may remain between the flat shell 44 and the sealing bracket 50 from other areas of the detector. This avoids the situation where the shielding block 60 weakens the radiation, resulting in insufficient sterilization intensity on the outside of the flat shell 44 corresponding to the shielded area of ​​the detector, which in turn contaminates other areas of the detector.

[0075] A virtual dividing line can be extended outward from the center of the flat shell 44, and the sealing cavity 55 can be located on either side of the virtual dividing line.

[0076] When the user unpacks and uses the detector, the second bracket 52 is fixed to the first recess 321, so the second bracket 52 will be removed along with the lower packaging shell 32, thus preventing the sealing bracket 50 from interfering with the user's use. Although the user has already unpacked the detector and the sealed cavity 55 is open, the detector has already been exposed to the outside world and used, so there is no longer any issue of bacteria contaminating other areas of the detector within the sealed cavity 55.

[0077] In an alternative embodiment, please refer to Figure 8 The detector also includes a packaging assembly, which comprises an upper packaging shell 31 and a lower packaging shell 32.

[0078] The upper packaging shell 31 is provided with a first convex shell 313, and the lower packaging shell 32 is provided with a second convex shell 323. The first convex shell 313 and the second convex shell 323 cooperate to form a convex cavity (not shown in the figure). The convex cavity is used to accommodate the shielding area of ​​the flat shell 44.

[0079] The outer walls of the first convex shell 313 and the second convex shell 323 are used to form the shielding block placement structure.

[0080] In this embodiment, the corresponding portions of the high-precision electronic components in the detection circuit board 43 protrude from the housing assembly, and the first convex shell 313 and the second convex shell 323 accommodate a portion of the detection circuit board 43. In this embodiment, the shielding block 60 can be disposed at the upper end of the first convex shell 313 and the lower end of the second convex shell 323, as well as on the sides of the first convex shell 313 and the second convex shell 323, so that the shielding block 60 blocks the radiation generated during the irradiation sterilization process.

[0081] In an alternative embodiment, please refer to Figure 9 The detector also includes a packaging assembly, the waist of which is recessed inward to form a third recess 33, the third recess 33 being correspondingly provided with the flat shell 44;

[0082] The third recess 33 is used to form the shielding block placement structure.

[0083] In this embodiment, when sterilizing the detector, it can be placed horizontally, i.e., the upper packaging shell 31 and the lower packaging shell 32 of the detector are on the same horizontal plane. A shielding block 60 is placed inside the third recess 33, controlling the radiation rays to shine from above the horizontally placed detector. The side of the detection circuit board 43 facing the radiation rays is only the side end of the detection circuit board 43. This means that only a small number of shielding blocks 60 are needed to block the radiation rays from hitting the detection circuit board 43, thereby reducing or eliminating the impact of the radiation rays on the detection circuit board 43 from that side.

[0084] In an alternative embodiment, please refer to Figure 10 The detector also includes a packaging component, the waist of which is recessed inward to form an annular groove 34, the annular groove 34 being correspondingly provided with the flat shell 44;

[0085] The annular groove 34 is used to form the shielding block placement structure.

[0086] In this embodiment, when sterilizing the detector, it can be placed horizontally, i.e., the upper packaging shell 31 and the lower packaging shell 32 of the detector are on the same horizontal plane. The shielding block 60 is set in the annular groove 34 to control the radiation rays to be directed at the detector from above or below when it is placed horizontally. The detection circuit board 43 faces only the side end of the detection circuit board 43 facing the radiation rays, and the shielding block 60 can be set at the periphery of the detection circuit board 43, thereby blocking the radiation rays directed at the detection circuit board 43 from any side end, thereby reducing or eliminating the influence of the radiation rays on the detection circuit board 43 on that side.

[0087] It should be noted that in any of the above embodiments, a sealing bracket 50 can be set at the corresponding position where the shielding block blocks the radiation to seal off bacteria in the corresponding area and prevent bacteria at that position from contaminating other areas of the detector.

[0088] In an optional embodiment, the detector further includes a packaging assembly, wherein the packaging assembly includes an upper packaging shell 31 and a lower packaging shell 32;

[0089] The upper packaging shell 31 is coupled to the lower packaging shell 32;

[0090] The lower packaging shell 32 is detachably snapped into the shell assembly.

[0091] Specifically, the lower packaging shell 32 is provided with a protruding edge 217, and the shell assembly is provided with a corresponding slot (not shown in the figure) that corresponds to the protruding edge 217. The protruding edge 217 on the lower packaging shell 32 engages with the slot to engage the lower packaging shell 32 with the shell assembly.

[0092] Furthermore, in this embodiment, the upper packaging shell 31 and the lower packaging shell 32 are threaded together.

[0093] The upper packaging shell 31 and the lower packaging shell 32 are threaded together. On the one hand, this allows the detector to fit more tightly with the packaging assembly, thus preventing accidental opening due to shaking during transportation. On the other hand, during the process of installing the detector into the packaging assembly, since the second bracket 52 is fixed to the first recess 321 of the lower packaging shell 32, the tightening of the upper packaging shell 31 and the lower packaging shell 32 provides a pre-tightening force to the sealing bracket 50. This allows the second bracket 52 to be closer to the first bracket 51, resulting in a tighter fit between the second bracket 52 and the first bracket 51, thereby ensuring the sealing performance of the sealing bracket 50.

[0094] When removing the packaging components, users can first remove the upper packaging shell 31 by spiraling it off. Since the protruding edge 217 and the slot are weakly connected, users can also easily remove the lower packaging shell 32.

[0095] Specifically, the engagement amount between the protruding edge 217 and the slot is between 0.2 mm and 0.5 mm, so as to maintain the engagement strength while making it easy for the user to remove.

[0096] In an optional embodiment, the detection component further includes a guide needle 42 for inserting into the sampling site;

[0097] The housing assembly includes an outer shell 210, a first cylindrical bracket 211, a second cylindrical bracket 212, a support bracket 213, and an elastic element 214;

[0098] The first cylindrical bracket 211 is slidably located within the outer casing 210;

[0099] The second cylindrical bracket 212 is slidably located inside the first cylindrical bracket 211, and the second cylindrical bracket 212 is provided with a through hole 2121;

[0100] A support bracket 213 is located inside the second cylindrical bracket 212, and the support bracket 213 extends outward with an elastic abutment portion 2131;

[0101] The elastic element 214 is compressed between the second cylindrical bracket 212 and the support bracket 213 so that the elastic abutment part 2131 abuts against the wall of the through hole 2121;

[0102] The outer shell 210 is used to drive the second cylindrical support 212 to move relative to the first cylindrical support 211. When the second cylindrical support 212 moves to the first predetermined position, the guide needle 42 and the probe are inserted into the sampling site. When it moves to the second predetermined position, the elastic abutment 2131 retracts inward so as to drive the guide needle 42 away from the sampling site through the elastic member 214.

[0103] In this embodiment, the elastic element 214 can be a spring. Since the elastic element 214 is compressed between the second cylindrical bracket 212 and the support bracket 213, the elastic element 214 applies a reciprocating elastic force to the second cylindrical bracket 212 and the support bracket 213. However, since the elastic abutment part 2131 abuts against the wall of the first through hole 2121, the elastic force generated by the elastic element 214 is applied to the wall of the first through hole 2121 through the elastic abutment part 2131, so that the second cylindrical bracket 212 and the support bracket 213 are also relatively stationary, and the elastic element 214 remains in a compressed state.

[0104] The guide needle 42 has a needle groove (not shown in the figure) to accommodate the probe (not shown in the figure), so that the guide needle 42 can break the skin of the sampling site and drive the probe to be implanted into the sampling site.

[0105] When a user uses the detector to perform a blood glucose test, they hold the outer casing 210 and align it with the sampling area, placing the first cylindrical support 211 against the vicinity of the sampling area. At this time, the guide needle 42 does not contact the sampling area. The outer casing 210 is then pushed towards the sampling area. Since the outer casing 210 is connected to the second cylindrical support 212, and the support bracket 213 abuts against the second cylindrical support 212 via the elastic abutment part 2131, the outer casing 210, while moving the second cylindrical support 212, can further move the support bracket 213 and the detection component towards the sampling area. As the second cylindrical support 212 moves the detection component, the guide needle 42 in the detection component gradually approaches the sampling area until the second cylindrical support 212 moves to a first predetermined position, at which point the guide needle 42 pierces the sampling area. The probe follows the guide needle 42 into the area, thus taking a sample. The probe transmits the data to the detection circuit board 43 to detect blood glucose levels.

[0106] The user continues to push the outer casing 210 towards the sampling area until the second cylindrical bracket 212 reaches the second predetermined position. At this time, the elastic abutment 2131 contacts the first guide and is squeezed by the first guide, causing the elastic abutment 2131 to contract inward until it moves out of the first through hole 2121. The elastic abutment 2131 no longer abuts against the wall of the first through hole 2121, and the support bracket 213 is no longer limited by the second cylindrical bracket 212. The elastic force generated by the compressed spring will push the support bracket 213 away from the detection component, thereby driving the guide needle 42 to move away from the sampling area, so that the guide needle 42 leaves the sampling area and can be quickly pulled out of the sampling area. Since the detection component is not connected to the support bracket 213, the probe will not be pulled out of the sampling area along with the guide needle 42, but will remain in the sampling area to enable continuous sampling and detection, thereby dynamically feeding back the detection results.

[0107] With the structure of the above-mentioned detector, the user can push the outer shell 210 and insert the probe into the sampling site through the guide needle 42. After the guide needle 42 brings the probe into the sampling site to a certain depth, the support bracket 213 is no longer limited by the second cylindrical bracket 212. The spring is released to quickly pull the guide needle 42 out of the sampling site along the insertion path. This reduces the likelihood of deviation from the trajectory or slow needle retraction, which could cause severe pain or skin damage to the person being tested, thus improving the experience for the person being tested.

[0108] In an alternative embodiment, such as Figure 12 As shown, the detection assembly also includes a shielding sheet 47, which is attached to the inner wall of the flat housing 44.

[0109] Specifically, there can be two shielding plates 47, which are sandwiched between the detection circuit board 43.

[0110] In this embodiment, the shielding sheet and the shielding block 60 have the same function: to block radiation rays from multiple directions that are directed toward the detection circuit board 43, thereby further reducing or eliminating the radiation effect of the radiation rays on the detection circuit board 43, and further reducing the possibility of the detection circuit board 43 malfunctioning due to radiation.

[0111] In one alternative example, the density of the shielding block 60 is greater than 1000 kg per cubic meter.

[0112] It is understandable that the higher the density of the shielding block 60, the better the shielding block 60 will be at blocking radiation.

[0113] In other alternative embodiments, please refer to Figure 11The detection circuit board 43 includes a PCB board and a high-density structure 65. The high-density structure 65 can be arranged around the high-precision electronic components in the detection circuit board 43 to further reduce the impact of radiation on the high-precision electronic components in the detection circuit board 43 by adjusting the layout of the components. It is understood that the high-density structure may include a battery.
