[0002] In a typical medical testing environment, subcutaneous sampling for testing requires the use of a diagnostic instrument. This instrument typically includes a device that drives a guide needle. During testing, the instrument moves the guide needle and probe to puncture the sampling site, allowing biometric data to be obtained via a circuit board within the instrument. To ensure medical safety, the instrument undergoes sterilization before leaving the factory or before sampling, usually through electromagnetic waves or irradiation. However, electromagnetic waves or irradiation can affect the circuit board within the instrument, causing malfunctions during the sterilization process. Summary of the Invention

In other words, this application can protect the detection circuit board from damage while ensuring sterilization of the detector by the irradiation rays. Simultaneously, at least a portion of the holographic shielding area is configured as a sealed area to prevent the entry of external objects, effectively reducing potential contamination from unsterilized holographic shielding areas and ensuring the safety and accuracy of the detection.

[0120] 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.

[0121] Please see Figures 1 to 24This application provides a detector, which includes a housing assembly, a detection assembly, and a shielding assembly; detailed description follows.

[0122] The detection assembly includes a first housing 21, a detection circuit board 22, and a probe (not shown); wherein, the detection circuit board 22 is disposed inside the first 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 inside the first housing 21, and the second end of the probe extends out of the first housing 21.

[0123] The housing assembly includes a sliding contact housing and a pressing part, and the detection component is located below the bottom of the pressing part; wherein, the contact housing is used to abut against the sampling part, the pressing part is used to drive the detection component to move toward 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.

[0124] The shielding component is disposed on one side of the first housing 21. When the detector is sterilized by radiation, the shielding component blocks part of the radiation, thereby forming a holographic shielding area 801 to protect the sensitive element 221. At least a portion of the holographic shielding area 801 can be configured as a sealed area to prevent the entry of external objects, thereby effectively reducing the potential contamination that may occur if the holographic shielding area 801 is not sterilized, and ensuring the safety and accuracy of the detection. The external objects can be external gases, dust, water vapor, etc., which may carry bacteria.

[0125] Sensitive element 221 is a high-precision electronic component that is easily affected by radiation and may malfunction.

[0126] Radiation includes, but is not limited to, X-rays, electron beams, and gamma rays.

[0127] When radiation rays strike the sensitive element 221 on the detection circuit board 22 from one side of the first housing 21, the shielding assembly can block the radiation rays striking the sensitive element 221 and form a total shadow shielding area 801 unaffected by the radiation rays. By adjusting the position and size of the shielding assembly so that the total shadow shielding area 801 formed by the shielding assembly covers the sensitive element 221, the radiation effect of the radiation rays on the sensitive element 221 is reduced or eliminated, thereby mitigating the situation where the sensitive element 221 malfunctions due to radiation, causing the detection circuit board 22 to malfunction. In other words, this application can protect the detection circuit board 22 from damage while ensuring that the radiation rays sterilize the detector.

[0128] In this embodiment, when sterilizing the detector, the detector can be placed below the irradiation source so that the holographic shielding area 801 formed by the shielding component can wrap around the sensitive element 221.

[0129] Specifically, the cross-section of the total shielding area 801 formed by the shielding components is triangular or polygonal.

[0130] Please see Figures 1 to 6 In an optional embodiment, the probe is introduced into the sampling site via a guide pin 25;

[0131] The abutting housing includes a first cylindrical support 11;

[0132] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a support bracket 13, and an elastic element 14;

[0133] The slidable portion of the first cylindrical bracket 11 is located inside the pressing shell 105, and the inner wall of the first cylindrical bracket 11 is provided with a protrusion 112;

[0134] The second cylindrical bracket 12 is slidably fitted inside the first cylindrical bracket 11. The second cylindrical bracket 12 includes a cylindrical structure 121 and a bottom plate 122. The cylindrical structure 121 is provided with a guide hole 1211 along the axial direction, and a positioning hole 1213 is provided along the path of the guide hole 1211. The outer edge of the bottom plate 122 extends with a plurality of connecting parts 1221, which are fixedly connected to the pressing shell 105.

[0135] The support bracket 13 is located inside the cylindrical structure 121, and the support bracket 13 extends outward with an elastic abutment portion 131;

[0136] The elastic element 14 is compressed between the bottom plate 122 and the top of the support bracket 13;

[0137] In the initial state, the elastic element 14 is in a compressed state, and the elastic abutment part 131 is located inside the positioning hole 1213;

[0138] 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, causing the protrusion 112 to move along the guide hole 1211; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a first predetermined position, the guide needle 25 guides the probe to pierce the sampling site; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a second predetermined position, the protrusion 112 pushes the elastic abutment 131 out of the positioning hole 1213, the elastic element 14 is released, and the guide needle 25 is driven away from the sampling site through the support bracket 13.

[0139] In this embodiment, the elastic element 14 can be a spring. Since the elastic element 14 is compressed between the bottom plate 122 and the top of the support bracket 13, the elastic element 14 will exert a reciprocating elastic force on the second cylindrical bracket 12 and the support bracket 13, but since the elastic abutment part 131 is located inside the positioning hole 1213, the elastic force generated by the elastic element 14 will push the elastic abutment part 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.

[0140] Specifically, the detector can be used to detect a variety of physical indicators. The following example uses blood glucose testing as an example.

[0141] When a user uses the detector to test blood glucose, they hold the press case 105 and align it with the sampling area, ensuring that one end of the case is close to the sampling area. At this point, the guide needle 25 is not in contact with the sampling area. The user then pushes the press case 105 closer to the sampling area. Since the press case 105 is connected to the second cylindrical support 12, and the support bracket 13 abuts against the second cylindrical support 12 via the elastic abutment part 131, the press case 105, while moving the second cylindrical support 12, can also move the support bracket 13 and the detection component closer to the sampling area. As the second cylindrical support 12 moves the detection component, the guide needle 25 in the detection component gradually approaches the sampling area until the second cylindrical support 12 moves to a first predetermined position, at which point the guide needle 25 pierces the sampling area. The probe follows the guide needle 25 and pierces the area, thus taking a sample. The probe transmits the data to the detection circuit board 22 to detect blood glucose levels.

[0142] The user continues to push the pressing shell 105 towards the side closer to the sampling area until the second cylindrical bracket 12 reaches the second predetermined position. At this time, the protrusion 112 pushes the elastic abutment 131 out of the positioning hole 1213. The elastic abutment 131 no longer abuts against the hole wall of the positioning hole 1213, and the support bracket 13 is no longer limited by the second cylindrical bracket 12. The elastic force generated by the compressed elastic element 14 will push the support bracket 13 away from the sampling area, thereby driving the guide needle 25 away from the sampling area, so as to quickly pull out the guide needle 25 from the sampling area. Since the detection component is not connected to the support bracket 13, the probe will not be pulled out of the sampling area together with the guide needle 25, but will remain in the sampling area to continuously sample and detect, thereby dynamically feeding back the detection results.

[0143] With the structure of the above-mentioned detector, the user can push the pressing shell 105 to 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. The spring is released to quickly pull the guide needle 25 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.

[0144] Furthermore, in this embodiment, the shielding assembly includes a shielding block fixing structure 31 and a shielding block 80;

[0145] The shielding block fixing structure 31 is fixed above the base plate 122, and the shielding block fixing structure 31 is provided with a shielding block receiving groove 311;

[0146] The shielding block 80 is detachably housed in the shielding block receiving groove 311 and is used to block radiation rays to form a total shadow shielding area 801 in a designated area.

[0147] It is understandable that after the detector is sterilized by irradiation, the shielding block 80 can be removed from the shielding block receiving slot 311 or left in the detector.

[0148] Specifically, the shielding block 80 has a cuboid structure. The density of the shielding block 80 is greater than 1000 kg per cubic meter. It can be understood that the higher the density of the shielding block 80, the better its effect in blocking radiation.

[0149] It should be noted that although the shielding block 80 can block the radiation, it also weakens the sterilization intensity of the radiation on the total shadow shielding area 801. This may result in insufficient sterilization intensity, which may not be able to completely sterilize the total shadow shielding area 801. Consequently, bacteria may still exist in the total shadow shielding area 801 inside the detector after irradiation sterilization, thus contaminating other areas of the detector.

[0150] Based on the above problems, in this embodiment, the detector further includes a sealing shell 40, which is located between the base plate 122 and the first housing 21. The sealing shell 40 and the outer wall of the first housing 21 form a first sealing cavity (not shown in the figure), and the first sealing cavity is correspondingly disposed with the shielding assembly. It can be understood that the holographic shielding area 801 includes at least a portion of the area where the first sealing cavity is located. The sensitive element can be disposed in the first sealing cavity.

[0151] Preferably, the cross-section of the first sealing cavity is greater than or equal to the cross-section of the total shadow shielding area formed by the shielding assembly.

[0152] There is a gap between the base plate 122 and the first housing 21, and this gap is located within the total shadow shielding area 801. Therefore, by setting a sealing shell 40 between the base plate 122 of the second cylindrical bracket 12 and the first housing 21, the gap between the two is wrapped into the first sealing cavity, thereby avoiding the situation where residual bacteria may exist in the gap between the two due to the weakening of radiation by the shielding block 80, which could then contaminate other areas of the detector.

[0153] 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. It can be understood that the holographic shielding area 801 includes at least a portion of the area where the second sealing cavity 44 is located. Specifically, the second sealing cavity 44 is used to enclose at least a portion of the holographic shielding area 801, that is, the area where the second sealing cavity 44 is located can be equal to or exceed the holographic shielding area 801.

[0154] The second sealing cavity 44 encloses at least part of the total image shielding area 801 to isolate bacteria that may remain in the total image shielding area 801 from other areas of the detector, thereby avoiding the situation where the shielding block 80 weakens the radiation irradiation, resulting in insufficient sterilization intensity of the total image shielding area 801 and thus contaminating other areas of the detector.

[0155] Furthermore, the detector also includes a packaging assembly, which includes a first housing 51 and a second housing 52, the first housing 51 and the second housing 52 being coupled to each other to enclose the housing assembly;

[0156] The sealing structure includes a first bracket 41 and a second bracket 42, wherein the first bracket 41 is fixed to the first housing 21 and the second bracket 42 is fixed to the second outer housing 52;

[0157] In the case where 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.

[0158] When the user unpacks and uses the detector, since the second bracket 42 is fixedly connected to the second outer shell 52, the second bracket 42 will be removed along with the second outer shell 52, thus preventing the second bracket 42 from interfering with the user's use. However, at this point, the user has already unpacked the detector, and the second sealed cavity 44 is open, but the detector has already been exposed to the outside world and used. Therefore, there is no longer any issue of bacteria contaminating other areas of the detector within the second sealed cavity 44.

[0159] Furthermore, please combine Figures 1 to 6 See Figure 7The first support 41 is a hollow cylinder, one end of the first support 41 is sealed to the first shell 21, and the other end of the first support 41 is provided with a mating groove 411.

[0160] The second support 42 is a hollow cylinder, and the end of the second support 42 away from the first support 41 is fixedly connected to the second outer shell 52;

[0161] In the case where the first outer shell 51 and the second outer shell 52 are coupled, the 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.

[0162] Specifically, the material of the first support 41 can be a soft material, including but not limited to silicone, TPU, rubber, plastic, etc. The soft material of the first support 41 can more tightly seal the connection with the second support 42, ensuring the airtightness of the connection between the two.

[0163] Optionally, in this embodiment, the first housing 51 and the second housing 52 are threaded together.

[0164] The threaded connection between the first outer shell 51 and the second outer shell 52 serves two purposes. First, it allows the detector to fit more tightly with the packaging assembly, thus preventing accidental opening due to shaking during transportation. Second, during the process of installing the detector into the packaging assembly, since the second bracket 42 is fixed to the second outer shell 52, tightening the first outer shell 51 and the second outer shell 52 provides a pre-tightening force to the bracket, allowing the second bracket 42 to move closer to the first bracket 41, resulting in a tighter fit between the second bracket 42 and the first bracket 41, thereby ensuring the seal of the bracket.

[0165] Furthermore, the detector also includes a shielding block placement structure for detachably placing the shielding block 80;

[0166] In the case where the shielding block 80 is placed in the shielding block placement structure, the shielding block 80 is used to block the radiation rays from hitting the sensitive element 221.

[0167] 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 irradiation.

[0168] In other alternative embodiments, such as Figure 9 As shown, the detector also includes a packaging assembly, which includes a first housing 51 and a second housing 52, the first housing 51 and the second housing 52 being coupled to each other to enclose the housing assembly;

[0169] The detector also includes a sealing structure located on the side of the first housing 21 away from the shielding assembly; the sealing structure has a second sealing cavity for enclosing at least a portion of the holographic shielding area; the sealing structure includes a first bracket 41 and a second bracket 42, the first bracket 41 being fixed to the first housing 21 and the second bracket 42 being fixed to the second outer housing 52.

[0170] The sealing structure also includes an isolation plate 45, which is disposed inside the second bracket 42 and is sealed to the inner wall of the second bracket 42.

[0171] The second outer shell 52 has through holes, which are correspondingly provided with the second bracket 42;

[0172] 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 holographic shielding area including the sensitive element.

[0173] 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 first housing 21 are arranged opposite each other to block the radiation on both sides of the sensitive element 221.

[0174] After irradiation sterilization, the shielding block 80 can be directly removed from the second bracket 42 through the through hole so that it can be installed in other detectors when sterilizing them, thus realizing the reuse of the shielding block 80.

[0175] In other alternative embodiments, the end face of the first housing is provided with a through hole;

[0176] The end face of the second outer shell is recessed inward to form a first recessed portion;

[0177] Correspondingly, the end of the housing assembly that is close to the first outer shell is recessed inward to form a second recess;

[0178] The through hole, the first recess, and the second recess are respectively arranged to form the shielding block placement structure.

[0179] When the shielding block is placed in the shielding block placement structure, the shielding block is located on opposite sides of the sensitive element to form a full-image shielding area that surrounds the sensitive element.

[0180] In another alternative embodiment, such as Figure 10As 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 shown in the figure). The convex cavity is used to accommodate the sensitive element 221 of the detection circuit board 22 in the first housing 21.

[0181] The outer walls of the first convex shell 511 and the second convex shell 522 are used to form the shielding block placement structure.

[0182] In this embodiment, the corresponding portions 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 accommodate a portion of the detection circuit board 22. In this embodiment, the shielding block 80 can be disposed 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 radiation generated during the irradiation sterilization process.

[0183] In another alternative embodiment, such as Figure 11 As shown, the waist of the packaging component is recessed inward to form a third recess 54, and the third recess 54 is correspondingly disposed with respect to the first shell 21;

[0184] The third recess 54 is used to form the shielding block placement structure.

[0185] The shielding block 80 is placed in the third recess 54 at the waist of the first housing 21, so that the shielding block 80 is located on the path of the radiation irradiation to the sensitive element 221, thereby reducing the possibility of the sensitive element 221 malfunctioning due to the radiation irradiation to the side of the sensitive element 221.

[0186] In another alternative embodiment, such as Figure 12 As shown, the waist of the packaging component is recessed inward to form an annular groove 55, which is correspondingly provided with the first housing 21;

[0187] The annular groove 55 is used to form the shielding block placement structure.

[0188] The shielding block 80 is placed in the annular groove 55 at the waist of the first housing 21, which can block the radiation rays coming from any side of the sensitive element 221, so that the shielding block 80 is located on the path of the radiation rays to the sensitive element 221, thereby reducing the impact of the radiation rays on the sensitive element 221.

[0189] In an optional embodiment, the guide pin 25 is fixedly connected to the support bracket 13, and one end of the guide pin 25 passes through the detection component;

[0190] The detector also includes a needle sleeve for accommodating the guide needle 25, one end of which is sealed to the first housing 21.

[0191] The needle sheath is sterilized by the radiation throughout the process, ensuring no bacteria remain. The guide needle 25 is housed within the needle sheath, isolating it from other parts of the detector. This prevents insufficient sterilization due to the shielding block 80 blocking the radiation, which could lead to contamination of the guide needle 25 by residual bacteria.

[0192] In other alternative embodiments, the other end of the needle sheath is fixedly connected to the second housing 52.

[0193] In other alternative embodiments, the detector further includes a shielding sheet disposed within the first housing, the shielding sheet being located on the path of the radiation rays directed toward the sensitive element, and forming a holographic shielding area enveloping the sensitive element.

[0194] Specifically, the shielding sheet can be positioned above the sensitive element 221 to form a holographic shielding area that covers the sensitive element 221.

[0195] Please combine Figures 1 to 12 See Figures 13 to 19 This application also provides a detector, which includes a housing assembly, a detection assembly, and a shielding assembly; wherein:

[0196] The detection assembly includes a first housing 21, a detection circuit board 22, and a probe; wherein, the detection circuit board 22 is disposed inside the first 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 inside the first housing 21, and the second end of the probe extends out of the first housing 21;

[0197] The housing assembly includes a sliding contact housing and a pressing part, and the detection component is located below the bottom of the pressing part; wherein, the contact housing is used to abut against the sampling part, the pressing part is used to drive the detection component to move toward 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.

[0198] The shielding component is disposed within the first housing 21; when the detector is sterilized by radiation, the shielding component blocks part of the radiation, thereby forming a holographic shielding area 801 that protects the sensitive element 221. Further, as... Figure 13As shown, a battery module 222 can also be provided on the detection circuit board 22. The battery module 222, the shielding component 80a and the sensitive element 221 are all arranged on the path of the irradiation source used for sterilization irradiating the detector, so that the battery module 222 and the shielding component 80a jointly block the radiation from the irradiation source from reaching the sensitive element 221.

[0199] The difference from the above embodiments is that the shielding component in the detector in this embodiment is disposed inside the first housing 21.

[0200] When radiation rays strike the sensitive element 221 on the detection circuit board 22 from one side of the first housing 21, the shielding assembly can block the radiation rays striking the sensitive element 221 and form a total shadow shielding area 801 unaffected by the radiation rays. By adjusting the position and size of the shielding assembly so that the total shadow shielding area 801 formed by the shielding assembly covers the sensitive element 221, the radiation effect of the radiation rays on the sensitive element 221 is reduced or eliminated, thereby mitigating the situation where the sensitive element 221 malfunctions due to radiation, causing the detection circuit board 22 to malfunction. In other words, this application can protect the detection circuit board 22 from damage while ensuring that the radiation rays sterilize the detector.

[0201] After the electron beam exits the accelerator, it passes through air, the sensor's outer surface, the casing, and other non-vacuum materials. These materials strongly scatter the electrons, but the electrons cannot penetrate the shielding assembly, creating a low-radiation region below it—the total shadow shielding region. Due to the varying electron scattering angles, there is still a radiation dose at the edges of the total shadow shielding region. The radiation dose is relatively low from the edge to the center and the upper part near the shielding assembly, increasing further away. By adjusting the structure and position of the shielding assembly, a relatively small radiation dose area within the total shadow shielding region can be created to surround the sensitive element.

[0202] Furthermore, the probe is guided into the sampling site via the guide pin 25;

[0203] The abutting housing includes a first cylindrical support 11;

[0204] The pressing part includes a pressing shell 105, a second cylindrical bracket 12, a support bracket 13, and an elastic element 14;

[0205] The slidable portion of the first cylindrical bracket 11 is located inside the pressing shell 105, and the inner wall of the first cylindrical bracket 11 is provided with a protrusion 112;

[0206] The second cylindrical bracket 12 is slidably fitted inside the first cylindrical bracket 11. The second cylindrical bracket 12 includes a cylindrical structure 121 and a bottom plate 122. The cylindrical structure 121 is provided with a guide hole 1211 along the axial direction, and a positioning hole 1213 is provided along the path of the guide hole 1211. The outer edge of the bottom plate 122 extends with a plurality of connecting parts 1221, which are fixedly connected to the pressing shell 105.

[0207] The support bracket 13 is located inside the cylindrical structure 121, and the support bracket 13 extends outward with an elastic abutment portion 131;

[0208] The elastic element 14 is compressed between the bottom plate 122 and the top of the support bracket 13;

[0209] In the initial state, the elastic member 14 is in a compressed state, and the elastic abutment part 131 is located inside the positioning hole 1213;

[0210] 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, causing the protrusion 112 to move along the guide hole 1211; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a first predetermined position, the guide needle 25 guides the probe to pierce the sampling site; when the second cylindrical bracket 12 moves relative to the first cylindrical bracket 11 to a second predetermined position, the protrusion 112 pushes the elastic abutment 131 out of the positioning hole 1213, the elastic element 14 is released, and the guide needle 25 is driven away from the sampling site through the support bracket 13.

[0211] In an alternative embodiment, such as Figure 13 and Figure 14 The shielding assembly includes a shielding frame, which is fixed to one side of the detection circuit board 22 where the sensitive element 221 is located. The shielding frame is used to block radiation rays to form a holographic shielding area 801 in a designated area.

[0212] When sterilizing the detector, the detector can be placed horizontally and its position adjusted so that the shielding frame is located on the path of the radiation rays to the sensitive element 221, so that the total shielding area 801 formed by the shielding frame protects the sensitive element 221 from the radiation rays.

[0213] In an alternative embodiment, such as Figure 15 As shown, the shielding assembly includes a shielding frame, which is fixed to the detection circuit board 22. The shielding frame is arranged around the periphery of the sensitive element 221 and is used to block radiation rays to form a holographic shielding area 801 in a designated area.

[0214] When sterilizing the detector, it can be placed horizontally. Since the shielding frame is set around the periphery of the sensitive element 221, the space inside the shielding frame is a total shielding area 801, which can block the radiation rays coming from any direction from the side of the sensitive element 221, so as to protect the sensitive element 221 from the influence of radiation rays.

[0215] In an alternative embodiment, please refer to Figures 16 to 18 The detection circuit board 22 is provided with fixing holes 227;

[0216] The shielding assembly includes a shielding frame, 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 the opposite ends of the connecting plate 71 to clamp the sensitive element 221.

[0217] When sterilizing the detector, the detector can be placed below the irradiation source, with the sensitive element 221 located between the two side baffles 72 and the connecting plate 71 located at one end of the sensitive element 221. This structure can block the irradiation rays from the sensitive element 221 in at least three directions. The total shadow shielding area 801 formed by the two side baffles 72 and the connecting plate 71 covers the sensitive element 221 to protect it from the irradiation rays.

[0218] Furthermore, such as Figure 19 As shown, the shielding structure also includes a vertical plate 73, which is located on the side of the detection circuit board 22 where the sensitive element 221 is located. One end of the vertical plate 73 is fixed to the opposite ends of the side baffle 72 located on that side.

[0219] The vertical plate 73 is disposed on the side baffle 72 and extends toward 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 total shadow shielding area 801 covering the sensitive element 221, which can better protect the sensitive element 221 from radiation.

[0220] Optionally, the shielding structure in the above embodiments can specifically be components in the detection circuit board, such as batteries, electromagnetic clips, and other components that meet the function of shielding radiation.

[0221] Optionally, the material of the shielding frame in the above embodiments is the same as that of the shielding block 80, both of which can achieve the function of blocking radiation.

[0222] It is understandable that the shape of the shielding structure is not limited to the above schemes. It can be set according to specific needs. For example, the cross-section of the shielding structure can also be curved, polygonal, etc., as long as the total shielding area formed by the shielding structure can wrap around the sensitive element.

[0223] Please combine Figures 20 to 27 This application also provides a detector, which has a structure that is basically the same as the detector described in the above embodiments. The components with the same structure are labeled with the same reference numerals, and the above components will not be described repeatedly. The following mainly describes the key parts of the detector provided in this embodiment or the parts that are different from other embodiments.

[0224] Specifically, please refer to Figure 21 and Figure 22 In this embodiment, the first housing 21 includes a support shell 211, a cover 212, and a sealing member 213. The support shell 211 is sealed to the cover 212 via the sealing member 213 to form a sealed storage cavity 210. The detection circuit board 22 is located in the storage cavity 210. It can be understood that the sealed area of ​​the holographic shielding region includes the storage cavity 210. By sealing the detection circuit board 22 entirely within the first housing 21, the potential contamination caused by the detection circuit board 22 not being sterilized can be more effectively reduced, ensuring the safety and accuracy of the detection.

[0225] Further, the first housing 21 has a through hole 214, one end of the probe 161 is located in the through hole 214, and one end of the probe 161 extends into the first housing 21 through a connector 163 passing through the hole wall of the through hole 214 to be electrically connected to the detection circuit board 162. The other end of the probe 161 extends out of the through hole 214 and extends in a direction away from the pressing part. The guide needle 15 includes a connecting rod 151 and a needle body 152 connecting the connecting rod 151. The connecting rod 151 is connected to the support bracket 13. The needle body 152 has a through hole that accommodates the probe 161 and is slidably connected to the probe 161.

[0226] It is understood that in other implementations, at least one of the carrier shell 211 and the cover 212 can be made of a flexible material, such as silicone. In this case, the sealing element 213 can be omitted, that is, the carrier shell 211 and the cover 212 can be directly sealed together.

[0227] Further, the supporting shell 211 may include a supporting plate 2111 and a side wall structure 2112 connecting the supporting plate 2111. The side wall structure 2112 has a sealing groove 2113. At least a portion of the sealing element 213 is located in the sealing groove 2113. The cover 212 includes a cover body 2121 and a protruding structure 2122 connecting the cover body 2121 and extending toward the supporting plate 2111. The protruding structure 2122 is used to press against the sealing element 213. The sealing element 213 may include sealant, a sealing ring, or a combination of sealant and a sealing ring.

[0228] Furthermore, please refer to Figure 23 A shielding component 80a is disposed on the detection circuit board 22. The shielding component 80a and the sensitive element 221 are arranged on the path T of the irradiation source for sterilization irradiating the detector, so that the shielding component 80a can block the radiation from the irradiation source from reaching the sensitive element 221. The irradiation direction D1 of the radiation is different from the pressing direction D2 of the pressing part. Specifically, the irradiation direction D1 of the radiation can be perpendicular to the pressing direction D2 of the pressing part.

[0229] A battery module 222 may also be disposed on the detection circuit board 22. The battery module 222, the shielding component 80a, and the sensitive element 221 are all arranged on the path T of the irradiation source used for sterilization irradiating the detector, so that the battery module 222 and the shielding component 80a jointly block the radiation from the irradiation source from reaching the sensitive element. It is understood that in other embodiments, the battery module 222 may also be replaced with other electronic devices, such as inductors, capacitors, resistors, chips, or other devices.

[0230] Furthermore, such as Figure 20-27 As shown, the detector includes a housing 10, a first cylindrical bracket 11, a second cylindrical bracket 12, a support bracket 13, an elastic element 14, a guide pin 15, and a detection assembly;

[0231] The first cylindrical support 11 is slidably located within the housing 10 and is partially located within the housing 10;

[0232] The second cylindrical bracket 12 is slidably located inside the first cylindrical bracket 11 and is connected to the housing 10 through the extended connecting part 1231. The second cylindrical bracket 12 is provided with a first through hole 124.

[0233] The support bracket 13 is located inside the second cylindrical bracket 12; the support bracket 13 extends outward with an elastic abutment portion 133.

[0234] The elastic element 14 is compressed between the second cylindrical bracket and the support bracket 13 so that the elastic abutment part 133 abuts against the wall of the first through hole 124;

[0235] A guide needle 15 is connected to the support bracket 13. The guide needle 15 is provided with a receiving groove 154. The guide needle 15 is used to pierce the sampling site.

[0236] A detection assembly is connected to the side of the first base plate 123 away from the second base plate of the support bracket 13, and the detection assembly includes a probe 161 partially accommodated in the receiving groove 154;

[0237] The housing 10 is used to move the second cylindrical support relative to the first cylindrical support 11. When the second cylindrical support moves to the first predetermined position, the guide needle 15 is inserted into the sampling site. When it moves to the second predetermined position, the elastic abutment 133 retracts inward so as to drive the guide needle 15 away from the sampling site through the elastic member 14.

[0238] The detection component can be used to detect various data of the human body, including but not limited to blood glucose levels, hemoglobin, white blood cell count, platelet count, etc. The following example uses blood glucose detection as an example.

[0239] In this embodiment, the elastic element 14 can be a spring. Since the elastic element 14 is compressed between the second cylindrical bracket and the support bracket 13, the elastic element 14 applies a reciprocating elastic force to the second cylindrical bracket and the support bracket 13. However, since the elastic abutment portion 133 abuts against the wall of the first through hole 124, the elastic force generated by the elastic element 14 is applied to the wall of the first through hole 124 through the elastic abutment portion 133, so that the second cylindrical bracket and the support bracket 13 are also relatively stationary, and the elastic element 14 remains in a compressed state.

[0240] When a user uses the detector to perform a blood glucose test, they hold the housing 10 and align the detection component with the sampling area, placing the first cylindrical support 11 against the vicinity of the sampling area. At this time, the guide needle 15 does not contact the sampling area. The housing 10 is then pushed towards the sampling area. Since the housing 10 is connected to the second cylindrical support, and the support bracket 13 abuts against the second cylindrical support via the elastic abutment part 133, the housing 10, by moving the second cylindrical support, can consequently move the support bracket 13, the guide needle 15, and the detection component towards the sampling area. As the second cylindrical support moves the guide needle 15, the guide needle 15 gradually approaches the sampling area until the second cylindrical support moves to a first predetermined position, at which point the guide needle 15 pierces the sampling area. Specifically, because the probe 161 lacks sufficient hardness, it is housed in the receiving groove 154. The detection component pierces the sampling area to bring the probe 161 into the sampling area, thereby taking a sample through the probe 161 to detect blood glucose levels.

[0241] The user continues to push the housing 10 towards the sampling area until the second cylindrical bracket reaches the second predetermined position. At this time, the elastic abutment 133 moves away from the housing 10 towards the first guide wall 126, that is, the elastic abutment 133 retracts inward, so that the elastic abutment 133 moves out of the first through hole 124. The elastic abutment 133 no longer abuts against the hole wall of the first through hole 124, and the support bracket 13 is no longer limited by the second cylindrical bracket. The elastic force generated by the compressed spring will push the support bracket 13 away from the first base plate 123, thereby driving the guide needle 15 away from the sampling area, so that the guide needle 15 leaves the sampling area and can be quickly pulled out from the sampling area. Since the detection component is not connected to the support bracket 13, the probe 161 of the detection component will not be pulled out of the sampling area along with the guide needle 15, but will remain in the sampling area to continuously sample and detect, thereby dynamically feeding back the detection results.

[0242] Through the above embodiments, the user can push the housing 10 and insert the probe 161 into the sampling site through the guide needle 15. After the guide needle 15 brings the probe 161 into the sampling site to a certain depth, the support bracket 13 is no longer limited by the second cylindrical bracket. The spring is released to quickly pull the guide needle 15 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.

[0243] In an optional embodiment, the detector has the following specific structure: a first cylindrical support 11 is partially located inside the housing 10. The first cylindrical support 11 is formed as a column with both ends through it and has a first cavity. The outer wall of the first cylindrical support 11 is provided with a travel hole 111, which can be a long strip-shaped hole.

[0244] The second cylindrical support includes a first base plate 123 and a first guide wall 126. The first base plate 123 is provided with a connecting part 1231, which passes through a travel hole 111 and connects to the housing 10. The connecting part 1231 can move along the length direction of the travel hole 111, and the travel hole 111 can limit the movement direction and maximum distance of the connecting part 1231. The first guide wall 126 is perpendicular to one side of the first base plate 123 and forms a second cavity. A first through hole 124 is provided on the first guide wall 126.

[0245] The support bracket 13 is located in the second cavity.

[0246] The first guide wall 126 can limit the position of the support bracket 13, making it less likely for the support bracket 13 to undergo horizontal displacement relative to the two-cylinder bracket; on the other hand, it can keep the insertion direction and withdrawal direction of the guide needle 15 consistent, avoiding injury to the user being tested due to inconsistent insertion and withdrawal directions.

[0247] In an optional embodiment, the first cylindrical support 11 is provided with a support wall that extends toward the sampling site and is used to abut against the sampling site.

[0248] The support wall is used to abut against the sampling site, and the length of the support wall is greater than the distance between the guide pin 15 and the sampling site, so as to reserve the travel space of the guide pin 15 by abutting against the sampling site through the support wall.

[0249] In an optional embodiment, the first cylindrical support 11 is provided with a first guide portion 113, which is partially located inside the first through hole 124. When the detection component moves to the second predetermined position, the first guide portion 113 pushes the elastic abutment portion 133 out of the first through hole 124.

[0250] As the user pushes the housing 10, causing the second cylindrical bracket to move along the length of the travel hole 111 towards the sampling location, the elastic abutment 133 gradually approaches the first guide portion 113. The elastic abutment 133 and the first guide portion 113 are provided with two inclined surfaces opposite each other. When the detection component moves to the second predetermined position, the inclined surface of the elastic abutment 133 contacts the inclined surface of the first abutment, and the elastic abutment 133 contracts inward along the inclined surface of the first guide portion 113, causing the first guide portion 113 to push the elastic abutment 133 out of the first through hole 124. The second cylindrical bracket no longer restricts the elastic abutment 133, and the elastic element 14 is released, causing the support bracket 13 to move away from the sampling location, thereby pulling the guide needle 15 out of the sampling location.

[0251] In an optional embodiment, the first base plate 123 is provided with a second through hole (not shown in the figure), and the guide pin 15 includes:

[0252] A connecting rod 151 passes through the second through hole. The connecting rod 151 includes a first end and a second end opposite to each other. The first end is fixed to the support bracket 13.

[0253] The needle body 152 is connected to the second end of the connecting rod 151. The needle body 152 is provided with the receiving groove 154. Please refer to the details. Figure 23 .

[0254] The support bracket 13 drives the connecting rod 151 to move, thereby driving the needle body 152 to move, so that the needle body 152 can be inserted into or withdrawn from the sampling site. Since the probe 161 is accommodated in the receiving groove 154, when the needle body 152 inserts into the sampling site, the probe 161 will also enter the sampling site.

[0255] Furthermore, the detection component includes:

[0256] The detection circuit board 162 is connected to the side of the first base plate 123 away from the support bracket 13 and is used to connect to the probe 161.

[0257] The detection circuit board 162 is also used to receive information detected by the probe 161 after it enters the sampling area. The detection circuit board 162 can also forward the received information to other terminals to inform the user of the specific information detected in various forms (such as text and charts).

[0258] In an optional embodiment, the inner wall of the housing 10 is provided with an arc-shaped protrusion 101, which is located on the side of the first bottom plate 123 facing the first guide wall 126;

[0259] The outer wall of the first cylindrical support 11 is provided with a first limiting part 117, which is located between the arc-shaped protrusion 101 and the first base plate 123 and abuts against the arc-shaped protrusion 101.

[0260] The user moves the housing 10 towards the sampling site. Before the second cylindrical support moves to the second predetermined position, the first limiting part 117 abuts against the arc-shaped protrusion 101. After contacting the arc-shaped protrusion 101, due to the elasticity of the first limiting part 117, the user applies a large pushing force to the housing 10, allowing the first limiting part 117 to gradually pass over the arc-shaped protrusion 101. Because the interference of the arc-shaped protrusion 101 with the first limiting part 117 slows down the user's pushing speed of the housing 10, after the first limiting part 117 moves to the highest point of the arc-shaped protrusion 101, the first cylindrical support 11 is no longer interfered with by the first limiting part 117. Due to inertia, the user maintains a large pushing force, causing the housing 10 and the second cylindrical support to move towards the sampling site with a large acceleration the instant the first limiting part 117 passes the highest point of the arc-shaped protrusion 101, thereby quickly inserting the needle-piercing component into the sampling site. The guide needle 15 can be inserted into the sampling site before the user fully feels the pain when it is inserted, thus preventing the user from slowing down the insertion process due to pain and causing greater pain.

[0261] In an optional embodiment, the outer wall of the second cylindrical bracket is provided with a first guide groove 125, and the inner wall of the first cylindrical bracket 11 is provided with a second guide portion (not shown in the figure) corresponding to the first guide groove 125.

[0262] The first guide groove 125 is used to limit the movement direction of the second guide part.

[0263] When the user controls the movement of the housing 10, the housing 10 drives the second cylindrical bracket to move, and the second guide part moves along the direction of the first guide groove 125, thereby limiting the movement of the housing 10 and the second cylindrical bracket and preventing the user from causing unstable movement and deviation due to improper operation.

[0264] In an optional embodiment, the outer wall of the first cylindrical support 11 is further provided with a second guide groove 119, and the inner wall of the housing 10 is further provided with a third guide portion 103 corresponding to the second guide groove 119;

[0265] The second guide groove 119 is used to limit the movement direction of the third guide part 103.

[0266] The cooperation between the second guide groove 119 and the third guide part 103 is basically the same as the cooperation between the first guide groove 125 and the second guide part. Both are used to prevent the user from making an improper operation that would cause unstable movement and deviation. This will not be elaborated further here.

[0267] In an alternative embodiment, please refer to Figure 25 and Figure 26 The detector also includes a shock-absorbing component 17, which is located on the side of the support bracket 13 away from the first base plate 123 and fixed to the inner wall of the housing 10.

[0268] When the elastic element 14 is released, the elastic force will push the support bracket 13 to one side. The support bracket 13 will collide with the housing 10, causing vibration, which may lead to the guide pin 15 deviating. The shock-absorbing component 17 can absorb the impact generated by the support bracket 13 in place of the housing 10 and weaken the vibration caused by the impact, thereby preventing the guide pin 15 from deviating due to vibration. Specifically, the shock-absorbing component 17 can be a sponge pad.

[0269] Please see Figures 28 to 30 This application embodiment also provides a detector assembly, which can adopt the detector described in any of the above embodiments and an outer packaging for sealing the detector. The outer packaging can include a main shell 61 and an easy-tear film 62. The main shell 61 has a receiving space and an opening communicating with the receiving space. The main shell 61 has an end face 611 surrounding the opening. The outer contour of the easy-tear film 62 is substantially consistent with the outer contour of the end face 611, and the easy-tear film 62 can be attached to the end face 611 by adhesive. The main shell 61 also has a first alignment structure 63. The bottom of the detector (such as on the second outer shell 52) can have a second alignment structure 56. The second alignment structure 56 is aligned and cooperates with the first alignment structure 63, so that the detector can be set in the main shell 61 in a preset position.

[0270] Further, please refer to Figure 31 In one modified embodiment, the main housing 61 may further be provided with a third alignment structure 64. The third alignment structure 64 is used to align with a fourth alignment structure 94 on the support frame 91 of the sterilization system, so that the orientation of the detector can be fixed, thereby facilitating sterilization of the detector using radiation light in a preset direction. The third alignment structure 64 can be an alignment groove. The fourth alignment structure 94 can be an alignment protrusion. It can be understood that, as Figure 32 As shown, in another modified embodiment, when the detector does not have the outer packaging, the third alignment structure 64 can be disposed on the outer surface of the detector (such as on the outermost housing).

[0271] Please combine Figures 1 to 32 See Figures 33 to 44 This application embodiment also provides a sterilization system, the sterilization system including a carrier frame 91, the carrier frame 91 being used in conjunction with an irradiation source 98 for sterilization;

[0272] The support frame 91 is located on one side of the irradiation source 98. The support frame 91 has multiple support parts on the side facing the irradiation source 98, and each support part can hold a detector as described in any of the above embodiments.

[0273] When the detector is placed inside the support, the support 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 source 98 irradiating the detector.

[0274] Irradiation source 98 can emit various types of radiation, including but not limited to X-rays, electron beams, and gamma rays.

[0275] When multiple detectors are subjected to irradiation sterilization at the same time, they can be placed in different support sections within the support frame 91. Since the radiation emitted by the irradiation source 98 is multi-directional, in order to ensure that each detector receives direct irradiation, the orientation of the detectors located within the support frame 91 is corrected in this embodiment to ensure that the shielding component or shielding block 80 can correctly achieve the shielding effect, that is, to form a total shadow shielding area 801 that encloses the sensitive element 221 and is not affected by the irradiation.

[0276] Furthermore, in this embodiment, the center of the carrier frame 91 is positioned corresponding to the irradiation source 98;

[0277] The support portion can be a support groove provided in the support frame 91. The support groove in the middle of the support frame 91 is vertically arranged, and the other support grooves adjacent to the middle support groove are inclined toward the side pointing to the irradiation source 98.

[0278] The farther the bearing trough is from the irradiation source 98, the greater its tilt angle.

[0279] Specifically, the carrier groove in the middle of the carrier frame 91 is directly opposite the irradiation source 98. The angle between the radiation emitted by the irradiation source 98 and the surface of the carrier frame 91 is a right angle, so the carrier groove is set vertically. The farther away from the irradiation source 98, the smaller the angle between the radiation emitted by the irradiation source 98 and the surface of the carrier frame 91. The tilt angle of the carrier groove is adjusted accordingly so that the central axis of all carrier grooves can point to the irradiation source 98, so as to ensure that the shielding component or shielding block 80 can correctly achieve the shielding effect, that is, form a total shadow shielding area 801 that surrounds the sensitive element 221 and is not involved by the radiation.

[0280] The placement of the detector is adjusted according to the formation method and location of the total shadow shielding area. The detector can be placed in the support frame 91 in a basically vertical manner or in a basically horizontal manner.

[0281] Further, please refer to Figure 38 In another embodiment, the sterilization system may further include at least one fastener 92 selected from magnetic fasteners and snap fasteners, said fastener 92 being used to fix the detector to the carrier frame.

[0282] Please see Figures 39 to 44 This application provides another sterilization system, which has a structure that is basically the same as the sterilization system described in the above embodiments. The components with the same structure are labeled with the same reference numerals, and the above components will not be described repeatedly. The following mainly describes the key parts of the sterilization system provided in this embodiment or the parts that are different from other embodiments.

[0283] In this embodiment, the support portion also has a plurality of first heat dissipation holes 911; the sterilization system further includes a cover plate 93, which is used to cover the side where the detector is located to cooperate with the support portion to fix the detector; the cover plate 93 has an alignment groove 931 for accommodating at least a portion of the detector and a plurality of second heat dissipation holes 932.

[0284] Furthermore, the main shell 61 of the outer packaging can also be provided with a third alignment structure 64. The third alignment structure 64 is used to align and cooperate with a fourth alignment structure 94 on the support frame 91 of the sterilization system, so that the orientation of the detector can be fixed, thereby facilitating sterilization of the detector using radiation light in a preset direction. In this embodiment, the third alignment structure 64 is an alignment groove, and the fourth alignment structure 94 is an alignment protrusion. It can be understood that, as Figure 32As shown, in another modified embodiment, when the detector does not have the outer packaging, the third alignment structure 64 can be disposed on the outer surface of the detector (such as on the outermost housing).

[0285] Specifically, in this embodiment, the main housing 61 further has a first alignment structure 63, and the bottom of the detector (such as on the second housing 52) has a second alignment structure 56. The second alignment structure 56 aligns and cooperates with the first alignment structure 63, so that the detector can be set in the main housing 61 according to a preset orientation. This arrangement ensures that when the detector is sterilized by radiation, the sensitive element 221 is within the holographic shielding zone 801, thereby protecting the sensitive element 221.
