Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a testing device. Background Technology

[0002] In the current field of medical devices, detection components are usually applied to the human body for detection, thus requiring a detection device that can apply the detection components to the human body. Utility Model Content

[0003] This application provides a detection device, which includes a detection component and a mounting frame. The mounting frame includes a support body and a spring arm. The support body is used to position the detection component on one side of the axial direction of the mounting frame. The spring arm is configured to elastically deform along the radial direction of the mounting frame and limit the detection component on the support body.

[0004] This application allows the detection component to be mounted via a mounting bracket. The elastic arm can undergo elastic deformation, thereby limiting the detection component to the bracket body. Simultaneously, the elastic arm can release the detection component during application to the human body. Furthermore, if the detection component tends to wobble and fall off when mounted on the bracket, the elastic deformation of the elastic arm can correct its position. Moreover, the elastic arm can also mitigate installation problems caused by manufacturing errors in the mounting bracket and / or the detection component. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0010] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0011] It should be understood that the terms “comprising” and “including” as used in this application indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0012] It should also be understood that the terminology used in this application is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this application, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0013] As used in this application, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determination" or "if [the described condition or event] is detected" may be interpreted, depending on the context, as "once determination," "in response to determination," "once [the described condition or event] is detected," or "in response to detection of [the described condition or event]."

[0014] This application describes a detection device that applies a detection component to a human body. For clarity and ease of understanding, in this description, the side of the detection component in contact with the human body is considered the lower side of the detection component in the vertical direction, the side of the detection component away from the human body is considered the upper side of the detection component in the vertical direction, the direction parallel to the contact surface between the detection component and the human body is considered the horizontal direction, the direction of the detection needle along the horizontal direction towards the detection component is considered radially inward, and the direction of the detection needle along the horizontal direction away from the detection component is considered radially outward. Unless otherwise specified, the positional descriptions of other related components will also be based on this. The purpose of the above description is merely to provide a reference direction for describing the relative positional relationships of various structures, and not to limit the actual structural arrangement of the embodiments in this application.

[0015] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 The diagram shows the structure of the detection device in some embodiments of this application. Figure 2 for Figure 1 The illustrated embodiment shows a schematic diagram of the detection device viewed from the side where the detection component contacts the human body. Figure 3 for Figure 2The illustrated embodiment shows a partial cross-sectional view of the detection device via an online VV diagram. The detection device 100 may include a main housing 10, an abutment 20, a mounting bracket 30, a puncture needle 40, and a detection assembly 50. The main housing 10 can accommodate all structures within the detection device 100, such as the abutment 20, the mounting bracket 30, the puncture needle 40, and the detection assembly 50. The abutment 20 can be slidably connected to the main housing 10 via a slide rail, slider, groove, sleeve, or abutment limiting method, as well as methods well known to those skilled in the art. The mounting bracket 30 can be slidably connected to the abutment 20 via a slide rail, slider, groove, sleeve, or abutment limiting method, as well as methods well known to those skilled in the art. The puncture needle 40 can be mounted on the mounting bracket 30. The puncture needle 40 can be used to pierce the human body to form an insertion channel. The detection assembly 50 can be mounted on the mounting bracket 30. The detection assembly 50 can be inserted into the human body with the assistance of the puncture needle 40 to perform human body state detection; specifically, the detection assembly 50 can be at least partially placed in the insertion channel.

[0016] When the testing device 100 is in its shelf life, i.e., not in use, the main housing 10 and the abutment 20 cooperate to lock the mounting bracket 30 on the abutment 20 (i.e., the mounting bracket 30 cannot slide relative to the abutment 20), and the main housing 10 and the mounting bracket 30 cooperate to lock the puncture needle 40 on the mounting bracket 30, so that the puncture needle 40 is mounted on the mounting bracket 30.

[0017] When the detection component 50 needs to be applied to the human body, i.e., when the detection device 100 is used, the abutment 20 needs to be placed against the human body. Pressing the main housing 10 causes the main housing 10 to move relative to the abutment 20. The main housing 10 triggers the abutment 20 to unlock the mounting bracket 30. The drive mechanism pushes the mounting bracket 30 to slide relative to the abutment 20 towards the side closer to the human body. Then, with the cooperation of the mounting bracket 30 and the puncture needle 40, the detection component 50 is ejected onto the surface of the human body. The detection component 50 is inserted into the human body with the assistance of the puncture needle 40 to perform human body status detection.

[0018] The main housing 10 moves relative to the abutment 20 to complete the process of applying the detection component 50 to the human body. At the same time, the mounting bracket 30 moves relative to the main housing 10 towards the side closer to the human body. The main housing 10 then triggers the mounting bracket 30 to unlock the puncture needle 40. The drive mechanism further pushes the puncture needle 40 relative to the mounting bracket 30 towards the side away from the human body. Then, with the cooperation of the mounting bracket 30 and the drive mechanism, the puncture needle 40 is pulled out of the human body (that is, during the process of applying the detection component 50 to the human body, the puncture needle 40 will pierce the human body, and at the same time, the detection component 50 will also pierce the human body), so that the detection component 50 remains on the human body, at least partially placed in the insertion channel.

[0019] It is understood that the detection device 100 may also include the drive mechanism described in the above embodiments.

[0020] In some embodiments, the sliding direction of the abutment 20 within the main housing 10 is parallel to the sliding direction of the mounting bracket 30 within the main housing 10 or the abutment 20.

[0021] In some embodiments, the main housing 10 and the abutment 20 may serve as housing assembly 200. Of course, housing assembly 200 may not be limited to the main housing 10 and the abutment 20, and may include others, which will not be elaborated further. In some embodiments, housing assembly 200 may also include the abutment 20 without including the main housing 10. In some embodiments, the abutment 20 may be part of the main housing 10. In some embodiments, the main housing 10 and the abutment 20 may be an integral structure and not slide relative to each other. In some embodiments, housing assembly 200 may serve as part of detection device 100. In some embodiments, the main housing 10 may be omitted.

[0022] In some embodiments, the puncture needle 40 may be omitted, while the detection component 50 may be directly inserted into the human body or inserted into the human body with the assistance of other structures to detect the human body status. Furthermore, other structures may also be part of the detection device 100.

[0023] In some embodiments, the detection component 50 may be disposed on the skin surface, for example, by adhesive bonding, and inserted into the human body. Alternatively, depending on changes in volume or detection type, it may be entirely embedded within the skin, and may be placed within the skin via a puncture needle 40 or other structures. Even in some embodiments, the detection component 50 may be disposed only on the skin surface without penetrating the skin, depending on changes in detection type and requirements.

[0024] In some embodiments, the drive mechanism may be omitted, and the mounting bracket 30 may slide relative to the abutment 20 under the operation of the user, or slide relative to the abutment 20 with the assistance of other structures, which may also be part of the detection device 100.

[0025] In some embodiments, the drive mechanism may be omitted, and the puncture needle 40 may be separated from the mounting bracket 30 and pulled out of the human body under the operation of the user, or separated from the mounting bracket 30 and pulled out of the human body with the assistance of other structures, and other structures may also be part of the detection device 100.

[0026] It is understandable that the function of the drive mechanism is to drive the mounting bracket 30 to move and drive the puncture needle 40 to move. Furthermore, in order to achieve the movement of the mounting bracket 30 and the puncture needle 40, the configuration of the drive mechanism is not limited to the embodiments listed herein, but may also be other.

[0027] Please see Figure 1The main housing 10 may be made of a rigid material. The main housing 10 may enclose a receiving space 1001 to accommodate all structures within the detection device 100, such as the abutment 20, mounting bracket 30, puncture needle 40, detection assembly 50, etc. In some embodiments, the main housing 10 may be omitted. In some embodiments, the main housing 10 may not be part of the housing assembly 200.

[0028] Please see Figure 4 and Figure 5 , Figure 4 for Figure 1 The schematic diagram of the main housing 10 in some embodiments shown is a structural diagram of some embodiments. Figure 5 for Figure 4 The illustrated embodiment is a schematic structural diagram of the main housing 10 from another perspective. The main housing 10 may include a body 11 having a receiving space 1001. The body 11 may form an opening end 1002. In some embodiments, the opening end 1002 allows the detection component 50 to pass from inside the receiving space 1001 through the opening end 1002 to outside the receiving space 1001 for application to a human body. In some embodiments, the main housing 10, such as the body 11, may be a cylindrical structure or a frame structure closed at one end and having an opening end 1002 at the other end. In some embodiments, the opening end 1002 may serve as the opening end of the housing assembly 200. In some embodiments, the opening end of the housing assembly 200 allows the detection component 50 to pass through.

[0029] Please see Figure 3 and Figure 6 , Figure 6 for Figure 1 The illustrated embodiment shows a schematic diagram of the abutment member 20 in some embodiments. The abutment member 20 may be made of a rigid material. The abutment member 20 may include a body 21 that is slidably connected to the main housing 10, such as the body 11, and has a receiving space 2001. The abutment member 20, such as the body 21, may have a cylindrical or frame structure and an opening end 2002 on one side. In some embodiments, the opening end 2002 allows the detection component 50 to move from inside the receiving space 1001 and the receiving space 2001 to outside the receiving space 1001 and the receiving space 2001 through the opening end 2002, so as to be applied to a human body. In some embodiments, the opening end 1002 may serve as the opening end of the housing assembly 200. In some embodiments, the opening end 1002 and the opening end 2002 cooperate to move the detection component 50 from inside the receiving space 1001 and the receiving space 2001 to outside the receiving space 1001 and the receiving space 2001. In some embodiments, opening ends 1002 and 2002 may serve as opening ends of housing assembly 200. In some embodiments, the opening ends of housing assembly 200 may allow detection assembly 50 to pass through. In some embodiments, body 21 may be slidably connected to mounting bracket 30.

[0030] Please see Figure 3 and Figure 7 , Figure 7 for Figure 3 The illustrated embodiment shows a schematic diagram of the mounting bracket 30 in some embodiments. The mounting bracket 30 can be made of rigid material and can be a frame structure, plate structure, column structure, or shell structure, etc. The mounting bracket 30 can be slidably disposed within the housing assembly 200, for example, the abutment member 20, to slide along the axial direction of the housing assembly 200, for example, the abutment member 20, toward the open end (e.g., open end 1002, open end 2002). Of course, in the scenario of assembling the testing device 100 or other scenarios, the mounting bracket 30 can also slide along the axial direction of the housing assembly 200, for example, the abutment member 20, toward the side away from the open end (e.g., open end 1002, open end 2002).

[0031] Understandably, the term "axial" as used in this application can refer to the actual central axis of a specific structure. However, when the specific structure is irregular, it can also be used to indicate the sliding direction or other meanings besides the central axis. Similarly, the term "radial" as used in this application can refer to the direction perpendicular to the central axis of a specific structure. However, when the specific structure is irregular, it can also be used to indicate the direction perpendicular to the sliding direction or other meanings besides the central axis.

[0032] In some embodiments, the mounting bracket 30 may be located within the receiving space 2001 and may slide within the receiving space 2001 toward the opening end (e.g., opening end 1002, opening end 2002). Of course, the mounting bracket 30 may also extend into the receiving space 1001 from the side away from the opening end (e.g., opening end 1002, opening end 2002).

[0033] Please see Figure 7 and Figure 8 , Figure 8 for Figure 7 The illustrated embodiment shows a schematic diagram of the mounting bracket 30 from another perspective. The mounting bracket 30 may include a first support 31 and a second support 32 axially connected to the housing assembly 200. The second support 32 may be closer to the opening end (e.g., opening end 1002, opening end 2002) than the first support 31. The first support 31 may be slidably connected to the housing assembly 200, for example, the abutment member 20, and can be used to mount the puncture needle 40, while the second support 32 can be used to mount the detection component 50.

[0034] Please see Figure 7 and Figure 9 , Figure 9 for Figure 7The illustrated embodiment shows a schematic diagram of the second bracket 32 ​​from another perspective. The second bracket 32 ​​may include a bracket body 321 and a spring arm 323. The bracket body 321 can be used to position the detection component 50, and the spring arm 323 can limit the detection component 50 on the bracket body 321, thereby realizing the installation of the detection component 50 on the mounting bracket 30.

[0035] In some embodiments, the support body 321 may be integrally formed with the first support 31. Furthermore, in some embodiments, the first support 31 may be a part of the support body 321. In some embodiments, the first support 31 may be omitted, and the support body 321 may be provided with structures on the first support 31 that cooperate with other structures in the detection device 100.

[0036] Please see Figure 8 The first bracket 31 can be connected to the second bracket 32, such as the bracket body 321, by means of snap-fit, screw-fit, plug-fit, welding, bonding, or other methods known to those skilled in the art.

[0037] The first bracket 31 may include a base plate 311 connected to the second bracket 32, such as bracket body 321, and a side plate 312 connected to the base plate 311 and surrounding a mounting groove 3001. In some embodiments, the side plate 312 may extend from the base plate 311 toward a side opposite to the second bracket 32, such as bracket body 321, to cooperate with the base plate 311 to form the mounting groove 3001. It is understood that the mounting groove 3001 is disposed on the side of the first bracket 31 opposite to the second bracket 32, such as bracket body 321.

[0038] In some embodiments, the mounting slot 3001 can be used to mount the puncture needle 40 and can accommodate the drive mechanism.

[0039] In some embodiments, a first perforation 3002 may be provided on the base plate 311 so that the puncture needle 40 can extend through the first perforation 3002 to the side of the base plate 311 near the second support 32, such as the support body 321, which also facilitates the insertion of the needle into the human body.

[0040] In some embodiments, the base plate 311 may be provided with a plurality of grippers 3111 within the mounting groove 3001. The plurality of grippers 3111 may surround the first perforation 3002 and cooperate to clamp the puncture needle 40, thereby locking and unlocking the puncture needle 40. When the plurality of grippers 3111 release the lock on the puncture needle 40, the drive mechanism may push the puncture needle 40 relative to the first support 31, such as the base plate 311, to move away from the human body, so that the puncture needle 40 moves from the first perforation 3002 to the side of the mounting groove 3001, thereby allowing the puncture needle 40 to be pulled out from the human body.

[0041] In some embodiments, the outer circumferential surface of the first bracket 31, such as the side plate 312, is evenly distributed with second elongated grooves 3121 for sliding connection with the abutment member 20. In some embodiments, the number of second elongated grooves 3121 may be 2, 3, 4, or 5, etc., and the specific number can be set according to the needs of those skilled in the art. In some embodiments, the number of second elongated grooves 3121 is sufficient to maintain stable sliding between the mounting bracket 30 and the abutment member 20.

[0042] In some embodiments, the outer side of the first bracket 31, such as the side plate 312, is provided with a retaining slider 3125 that abuts against the inner wall surface of the abutment 20, so as to enhance the stability of the sliding between the mounting bracket 30 and the abutment 20 by the retaining slider 3125.

[0043] In some embodiments, the first bracket 31, for example, the base plate 311, may be provided with a clearance groove 3124 on the side facing the second bracket 32, for example, the bracket body 321. The clearance groove 3124 can make way for the abutment member 20. In some embodiments, the clearance groove 3124 may extend away from the second bracket 32, for example, the bracket body 321, and extend to the side plate 312. In some embodiments, the clearance groove 3124 may communicate with the mounting groove 3001.

[0044] Please see Figure 7 The first bracket 31, for example, has a first locking portion 3122 and a second locking portion 3123 on its outer side, for locking or unlocking with the abutment member 20, for example, the main body 21. In some embodiments, the first locking portion 3122 and the second locking portion 3123 may be grooves, and in other embodiments, they may be other structures such as protrusions. In some embodiments, the first locking portion 3122 is closer to the opening end (e.g., opening end 1002, opening end 2002) than the second locking portion 3123. In some embodiments, the first locking portion 3122 may extend away from the opening end (e.g., opening end 1002, opening end 2002), and the second locking portion 3123 may extend toward the opening end (e.g., opening end 1002, opening end 2002) and may extend to the base plate 311 and / or the second bracket 32, for example, the bracket body 321.

[0045] Understandably, when the first bracket 31 is part of the bracket body 321, the first locking part 3122 and the second locking part 3123 can be provided on the bracket body 321.

[0046] Please combine Figure 3As shown, during the sliding process of the mounting bracket 30, such as the bracket body 321, relative to the housing assembly 200, such as the abutment member 20, toward the open end (e.g., open end 1002, open end 2002), the mounting bracket 30, such as the bracket body 321, switches from a first state in which the first locking part 3122 is snapped into contact with the housing assembly 200, such as the abutment member 20, to a second state in which the second locking part 3123 is snapped into contact with the housing assembly 200, such as the abutment member 20. The elastic arm 323 can limit the detection component 50 on the bracket body 321 during the first state.

[0047] In some embodiments, the elastic arm 323 can limit the detection component 50 on the support body 321 in the second state. At this time, the detection component 50 can be connected to the human body to be applied to the human body. When the detection device 100 is removed, the limiting force of the elastic arm 323 on the detection component 50 in the second state is less than the connection force between the detection component 50 and the human body, thereby allowing the detection component 50 to detach from the support body 321 and remain on the human body.

[0048] Of course, in some embodiments, the elastic arm 323 may also release the detection component 50 from the support body 321 in the second state.

[0049] Please see Figure 7 and Figure 9 In some embodiments, the elastic arm 323 may have a connecting end 3201 connected to the support body 321, and a free end 3202. The elastic arm 323 bends and elastically deforms around the connecting end 3201, allowing the free end 3202 to move. In some embodiments, the elastic arm 323 may be directly connected to the support body 321 at the connecting end 3201 or detachably connected. In some embodiments, the elastic arm 323 and the support body 321 may be integrally formed.

[0050] Please see Figure 2 and Figure 3 When the mounting bracket 30, such as the second bracket 32, is used to install the detection component 50, the portion of the elastic arm 323 between the connecting end 3201 and the free end 3202 can abut against the housing assembly 200, such as the abutment member 20. This allows the elastic arm 323 to elastically deform along the radial direction (perpendicular to the axial direction of the housing assembly 200), thereby allowing the free end 3201 to inelastically or elastically abut against the detection component 50, thus limiting the detection component 50 to the bracket body 321. In some embodiments, when there are multiple elastic arms 323, some elastic arms 323 may not abut against the detection component 50, or all of them may abut against the detection component 50, thus limiting the detection component 50 to the bracket body 321.

[0051] In some embodiments, the free end 3201 is inelastically abutted against the detection component 50. However, when there are processing errors in the housing assembly 200, mounting bracket 30, or detection component 50, the free end 3201 may elastically abut against the detection component 50. Furthermore, when the detection component 50 tends to wobble and fall off due to processing errors or other reasons, it may touch the free end 3201, causing the elastic arm 323 to elastically deform. This elastic deformation further pushes the detection component 50 to correct its position, ensuring that the detection component 50 does not shift.

[0052] In some embodiments, when the free end 3201 elastically abuts against the detection component 50, the elastic deformation of the elastic arm 323 can adapt to the outer periphery of the detection component 50. Furthermore, if the housing assembly 200, mounting bracket 30, or detection component 50 has manufacturing errors, the rigid abutment between the housing assembly 200, mounting bracket 30, and detection component 50 may cause the detection component 50 to deviate from its preset installation position on the mounting bracket 30. This may also lead to unstable installation of the detection component 50 on the mounting bracket 30, or even prevent the detection component 50 from being installed on the mounting bracket 30 at all. The elastic arm 323 can mitigate these problems by utilizing its elastic deformation to adapt to the abutment and engagement scenarios of the elastic arm 323 and the housing assembly 200, and vice versa.

[0053] In some embodiments, the elastic arm 323 has a protruding abutment portion 3231 located between the connecting end 3201 and the free end 3202, which can abut against the housing assembly 200, such as the abutment member 20. In some embodiments, the abutment portion 3231 can be correspondingly provided with a relief groove 3124, thereby allowing the portion of the housing assembly 200, such as the abutment member 20, that abuts against the abutment portion 3231 to slide into the relief groove 3124. In some embodiments, when the radial dimension of the support body 321 is large enough, it will block the relief groove 3124, and thus the relief groove 3124 can also be provided on the support body 321.

[0054] Understandably, when the first bracket 31 is part of the bracket body 321, the clearance groove 3124 can be provided on the bracket body 321.

[0055] Please see Figure 6The abutment member 20, for example, has first elongated grooves 211 evenly distributed around its outer circumference for sliding connection with the main housing 10, for example, the body 11. In some embodiments, the number of first elongated grooves 211 may be 2, 3, 4, or 5, etc., and the specific number can be set according to the needs of those skilled in the art. In some embodiments, the number of first elongated grooves 211 is sufficient to maintain stable sliding between the abutment member 20 and the main housing 10, for example, the body 11.

[0056] The abutment member 20, for example, has a latching portion 212 on its outer side, for locking and unlocking with the abutment member 20, for example, the main body 21, and for abutting and limiting the main housing 10, for example, the body 11. In some embodiments, the latching portion 212 may be a hook-shaped structure. In some embodiments, the latching portion 212 may include a first latching portion 2121 and a second latching portion 2122. In some embodiments, the first latching portion 2121 and the second latching portion 2122 cooperate to abut and limit the main housing 10, for example, the body 11. In some embodiments, the first latching portion 2121 may limit the movement of the abutment member 20, for example, the main body 21, relative to the main housing 10, for example, the body 11 towards the opening end 1002.

[0057] In some embodiments, the second latching portion 2122 can lock and unlock with the abutment 20, such as the main body 21, and can abut with the main housing 10, such as the body 11. In some embodiments, the second latching portion 2122 is latched to the first locking portion 3122 in a first state, limiting the movement of the mounting bracket 30 relative to the housing assembly 200 toward the opening end (e.g., opening end 1002, opening end 2002). In some embodiments, the second latching portion 2122 is latched to the second locking portion 3123 in a second state, limiting the movement of the mounting bracket 30 relative to the housing assembly 200 toward the side away from the opening end (e.g., opening end 1002, opening end 2002). This can prevent the mounting bracket 30 from sliding when the user presses the mounting bracket 30 after using the detection device 200, further avoiding repeated loading of the detection assembly 50, and also avoiding cross-infection problems caused by repeated use of the detection device 200. It can also prevent the user from being accidentally pricked by the puncture needle 40 inside the detection device 200.

[0058] Please see Figure 3When in use, the main housing 10, for example, the body 11, is pressed, causing the abutment 20, for example, the main body 21, to slide into the main housing 10, for example, the accommodating space 1001. The second latching part 2122 disengages from the abutment of the main housing 10, for example, the main body 11, and moves radially away from the first locking part 3122, thereby disengaging from the latching connection with the first locking part 3122. This releases the locking of the abutment 20, for example, the main body 21, to the mounting bracket 30, allowing the mounting bracket 30 to slide out of the main housing 10, for example, the accommodating space 1001. Consequently, the second latching part 2122 can latch into the second locking part 3123, preventing the mounting bracket 30 from sliding into the main housing 10, for example, the accommodating space 1001.

[0059] Please see Figure 6 The inner wall of the abutment 20, such as the main body 21, is circumferentially distributed with second elongated sliders 213. These second elongated sliders 213 can be accommodated within second elongated grooves 3121 to achieve a sliding connection between the abutment 20, such as the main body 21, and the mounting bracket 30. In some embodiments, at least one second elongated slider 213 can be accommodated within a second elongated groove 3121. In some embodiments, the number of second elongated sliders 213 can be 2, 3, 4, or 5, etc., and the specific number can be set according to the needs of those skilled in the art. In some embodiments, the number of second elongated sliders 213 is sufficient to maintain stable sliding between the mounting bracket 30 and the abutment 20.

[0060] In some embodiments, the abutment member 20, for example, may have a pressing portion 214 on the inner wall of the main body 21, to abut against the elastic arm 323, for example, the abutment portion 3231. In some embodiments, the relief groove 3124 may accommodate the pressing portion 214 when the mounting bracket 30 moves axially toward the opening end (e.g., opening end 1002, opening end 2002) relative to the housing assembly 200. The provision of the relief groove 3124 ensures that the protrusion length of the abutment portion 3231 is not too long. If the protrusion length of the abutment portion 3231 is too long, it will be too close to the inner wall surface of the housing assembly 200, affecting the elastic deformation space of the elastic arm 323.

[0061] In some embodiments, the abutment portion 3231 and the contact portion 3232 are spaced apart along the extending direction of the free end 3202. After the detection device 100 is assembled, this provides a space for elastic deformation of the elastic arm 323 and the detection component 50, preventing the detection component 50 from deviating from the axis. When the free end 3201 elastically abuts against the detection component 50, the elastic arm 323 provides a space for elastic deformation to adapt to the outer periphery of the detection component 50. Furthermore, if the housing assembly 200, the mounting bracket 30, or the detection component 50 has processing errors, the rigid abutment between the housing assembly 200, the mounting bracket 30, and the detection component 50 may cause the detection component 50 to deviate from its preset installation position on the mounting bracket 30. This may also lead to unstable installation of the detection component 50 on the mounting bracket 30, or even prevent the detection component 50 from being installed on the mounting bracket 30 at all. These problems can be improved by using the elastic arm 323 to provide elastically deformable space, to adapt to the scenario where the elastic arm 323 abuts and cooperates with the housing assembly 200, and to adapt to the scenario where the elastic arm 323 abuts and cooperates with the detection assembly 50.

[0062] Please see Figure 9 A contact portion 3232 is protruding from the free end 3202 near the detection component 50. The contact portion 3232 is used to limit the detection component 50. The contact portion 3232 allows the portion of the elastic arm 323 between the contact portion 3232 and the connecting end 3201 to be spaced apart from the detection component 50, increasing the space for elastic deformation of the elastic arm 323. It also ensures stable contact and cooperation between the elastic arm 323 and the detection component 50.

[0063] In some embodiments, when the detection component 50 is installed on the mounting bracket 30, the portion of the elastic arm 323 between the abutment portion 3231 and the free end 3202 (or contact portion 3232) can have elastic deformation. This allows the elastic arm 323 to simultaneously adapt to both the scenario where the elastic arm 323 abuts against the housing component 200 and the scenario where the elastic arm 323 abuts against the detection component 50. This enables the stable installation of the detection component 50 on the mounting bracket 30, such as the second bracket 32, while also changing the rigid abutment mechanism of the housing component 200, the mounting bracket 30, and the detection component 50. This also mitigates the risks caused by processing errors in the housing component 200, the mounting bracket 30, or the detection component 50.

[0064] In some embodiments, the support body 321 is provided with a receiving groove 3003 on the side facing the opening end (e.g., opening end 1002, opening end 2002), the receiving groove 3003 can accommodate the detection component 50 to position the detection component 50.

[0065] Please see Figure 7 and Figure 9 The bottom of the receiving groove 3003 is provided with a second perforation 3004. The second perforation 3004 is opposite to and communicates with the first perforation 3002, so that the puncture needle 40 can extend into the receiving groove 3003 through the first perforation 3002 and the second perforation 3004 to cooperate with the detection component 50.

[0066] In some embodiments, the bottom of the receiving groove 3003 is provided with a support rib 3211 to support the detection component 50 and reduce the risk that the bottom of the receiving groove 3003 may not be able to stably support the detection component 50 due to processing errors.

[0067] In some embodiments, the receiving groove 3003 may have a sidewall 322. The sidewall 322 may be provided with a notch 3005, and a spring arm 323 may be provided in the notch 3005 to cooperate with the detection component 50 at the notch 3005. In some embodiments, the spring arm 323 may be machined from the sidewall 322, thereby simplifying the machining difficulty of the second bracket 32.

[0068] In some embodiments, a support protrusion 3221 may be provided on the sidewall 322 to support the detection component 50, thereby reducing the risk that the sidewall 322 may not be able to stably or effectively support the detection component 50 due to processing errors.

[0069] In some embodiments, the number of elastic arms 323 may be more than one, such as symmetrically arranged first and second elastic arms, which may be spaced apart circumferentially around the detection component 50. The symmetrical arrangement of multiple elastic arms 323 allows for stable mounting of the detection component 50 on the mounting bracket 30. In some embodiments, the sidewall 322 may have a notch 3005 for each elastic arm 323.

[0070] Please see Figure 10 , Figure 10 for Figure 7The illustrated embodiment shows a schematic diagram of the second bracket 32 ​​from another perspective. The elastic arm 323, corresponding to the abutment portion 3231, has an adjustment groove 3234 on the side away from the opening end (e.g., opening end 1002, opening end 2002). The adjustment groove 3234 is configured to extend towards the edge of the elastic arm 323 near the detection component 50, thereby forming an opening on the side of the elastic arm 323 near the detection component 50. By adjusting the groove 3234 and the opening, the deformation direction and force of the elastic arm 323 can be adjusted, so that the deformation direction of the elastic arm 323 at the corresponding abutment portion 3231 can form an angle with both the axial and radial directions of the housing assembly 200. When the mounting bracket 30 slides relative to the housing assembly 200, for example, the abutment member 20, the abutment portion 3231 will be subjected to a force away from the opening end (e.g., opening end 1002, opening end 2002). The adjusting groove 3234 and the opening can alleviate the direct transmission of this force to the detection component 50, reduce the impact on the detection component 50, and make the detection component 50 stably mounted on the mounting bracket 30. In some embodiments, the adjusting groove 3234 can be a through groove.

[0071] Please see Figure 2 The contact portion 3232 can generate an axial component force on the detection component 50 along the axial direction of the housing assembly 200 and toward the bracket body 321, thereby pressing the detection component 50 onto the bracket body 321 and improving the installation stability of the detection component 50 on the mounting bracket 30. In addition, when the detection component 50 is offset, the contact portion 3232 can elastically abut against the detection component 50 due to the elastic deformation of the elastic arm 323, thereby pressing the detection component 50 onto the bracket body 321. In some embodiments, the elastic deformation of the elastic arm 323 causes the contact portion 3232 to elastically abut against the detection component 50 due to the elastic deformation of the elastic arm 323, thereby pressing the detection component 50 against the bracket body 321 and improving the installation stability of the detection component 50 on the mounting bracket 30.

[0072] Please see Figure 11 , Figure 11 for Figure 9 The illustrated embodiment shows a reference cross-sectional view of the second bracket 32 ​​along line XIII-XIII. The contact portion 3232 is provided with an abutment surface 3233 that contacts the detection component 50, in a reference cross-section parallel to the axial direction (e.g., ...). Figure 11 Inside the contact, the contact surface 3233 is inclined or bent toward the side closer to the detection component 50 in the direction near the opening end (e.g., opening end 1002, opening end 2002). This allows the contact portion 3232 to generate an axial component force on the detection component 50 in the axial direction and toward the support body 321, thereby pressing the detection component 50 onto the support body 321.

[0073] Please see Figure 2 and Figure 12 , Figure 12 for Figure 2 The illustrated embodiment shows a schematic diagram of the structure of the second bracket 32 ​​cooperating with the detection component 50. A positioning groove 5002 is provided on the side periphery of the detection component 50, and the contact portion 3232, for example, the abutment surface 3233, abuts against the bottom of the positioning groove 5002. In a reference section parallel to the axial direction, the bottom of the positioning groove 5002 is inclined or bent towards the side away from the contact portion 3232 in the direction near the opening end (e.g., opening end 1002, opening end 2002), so as to cooperate with the contact portion 3232, for example, the abutment surface 3233, so that the contact portion 3232 can generate an axial component force on the detection component 50 along the axial direction and toward the bracket body 321, thereby pressing the detection component 50 onto the bracket body 321.

[0074] Please refer to the following: Figure 3 and Figure 6 The holding portion 214 may be provided protruding on the inner wall of the housing assembly 200, such as the abutment member 20, so as to abut against the elastic arm 323, such as the abutment portion 3231. The holding portion 214 may be released from abutment against the abutment portion 3231 after the mounting bracket 30 moves a predetermined distance axially relative to the housing assembly 200 toward the opening end (e.g., opening end 1002, opening end 2002).

[0075] In some embodiments, when the holding part 214 and the abutting part 3231 are released from contact, the elastic arm 323 can limit the detection component 50 on the support body 321. At this time, the detection component 50 can be connected to the human body to be applied to the human body. When the detection device 100 is removed, the limiting force of the elastic arm 323 on the detection component 50 is less than the connection force between the detection component 50 and the human body, thereby allowing the detection component 50 to detach from the support body 321 and remain on the human body.

[0076] Of course, in some embodiments, when the holding part 214 and the abutting part 3231 are released from contact, the elastic arm 323 may not act on the detection component 50, thereby allowing the detection component 50 to separate from the mounting bracket 30 and be applied to the human body.

[0077] In some embodiments, the holding portion 214 includes a retaining section 2141 and a releasing section 2142 connected sequentially along the axial direction. The releasing section 2142 is closer to the opening end (e.g., opening end 1002, opening end 2002) than the retaining section 2141. In the direction close to the opening end (e.g., opening end 1002, opening end 2002), the protrusion height of the releasing section 2142 relative to the inner wall of the housing assembly 200 gradually decreases, and the protrusion height of the retaining section 2141 relative to the inner wall of the housing assembly 200 is not less than the maximum protrusion height of the releasing section 2142 relative to the inner wall of the housing assembly 200. Furthermore, when the mounting bracket 30 slides axially toward the open end (e.g., open end 1002, open end 2002), the elastic arm 323, for example, changes from abutting part 3231 abutting with holding section 2141 to abutting with release section 2142. During this process, the elastic arm 323 moves radially away from the detection component 50 while abutting with release section 2142, thereby preventing the elastic arm 323 from acting on the detection component 50. This allows the detection component 50 to separate from the mounting bracket 30 and be applied to the human body, thus achieving automatic release of the detection component 50.

[0078] Please see Figure 4 and Figure 5 The inner wall of the main housing 10, such as the body 11, is circumferentially distributed with first elongated sliders 111 for sliding connection with the abutment 20. In some embodiments, a plurality of first elongated sliders 111 are correspondingly arranged with a plurality of first elongated grooves 211, such that a first elongated groove 211 accommodates at least one first elongated slider 111, thereby realizing the sliding connection between the main housing 10, such as the body 11, and the abutment 20, such as the body 21.

[0079] In some embodiments, the number of first elongated sliders 111 may be 2, 3, 4, or 5, etc., and the specific number can be set according to the needs of those skilled in the art. In some embodiments, the number of first elongated sliders 111 may be sufficient to maintain the stable sliding of the main housing 10, such as the body 11, and the abutment 20, such as the main body 21.

[0080] In some embodiments, to achieve stable sliding of the abutment 20 within the main housing 10, such as the body 11, an abutment slider 1111 is provided adjacent to the first elongated slider 111 to abut against and limit the movement of the abutment 20. In some embodiments, the number of abutment sliders 1111 may be less than the number of the first elongated sliders 111. In some embodiments, the number of abutment sliders 1111 may be half the number of the first elongated sliders 111. In some embodiments, the number of abutment sliders 1111 may be 2, 3, 4, or 5, etc., and the specific number can be set according to the needs of those skilled in the art. In some embodiments, the number of abutment sliders 1111 is sufficient to maintain stable sliding between the main housing 10, such as the body 11, and the abutment 20, such as the body 21.

[0081] A first retaining portion 112 may be provided on the inner wall of the main housing 10, such as the body 11, to abut and limit the contact member 20, such as the latching portion 212. In some embodiments, the first retaining portion 112 may be a protrusion. Of course, it may also be other structures that can be snapped together. In some embodiments, the first retaining portion 112 may abut and cooperate with the first latching portion 2121 to limit the movement of the contact member 20, such as the body 21, relative to the main housing 10, such as the body 11, toward the opening end 1002. In some embodiments, the first retaining portion 112 may cooperate with the second latching portion 2122 to lock and unlock the contact member 20, such as the body 21.

[0082] Please see Figure 3 When in use, the main housing 10, for example, the body 11, is pressed, causing the abutment 20, for example, the main body 21, to slide into the main housing 10, for example, the accommodating space 1001. The second latching part 2122 disengages from the abutment of the first holding part 112 and moves radially away from the first locking part 3122, thereby disengaging from the latching connection with the first locking part 3122. This releases the locking of the abutment 20, for example, the main body 21, to the mounting bracket 30, allowing the mounting bracket 30 to slide out of the main housing 10, for example, the accommodating space 1001. Consequently, the second latching part 2122 can latch into the second locking part 3123, preventing the mounting bracket 30 from sliding into the main housing 10, for example, the accommodating space 1001.

[0083] Please see Figure 3 The gripper 3111 can be in a retracted state, thereby gripping and limiting the puncture needle 40. The first support 31, such as the base plate 311, cannot move in direction F2. When the first support 31, such as the base plate 311, moves in direction F1, the gripper 3111 can release the lock on the puncture needle 40, allowing the drive mechanism to push the puncture needle 40 relative to the first support 31, such as the base plate 311, to move away from the human body, so that the puncture needle 40 moves from the first perforation 3002 to the mounting groove 3001, so that the puncture needle 40 can be pulled out from the human body.

[0084] Please see Figure 12 The detection component 50 may include a detection body 51 and a detection needle 52 disposed on the detection body 51 and cooperating with the puncture needle 40. The detection body 51 serves as the main structure of the detection component 50, receiving data signals detected by the detection needle 52, processing the data signals to generate detection results, and connecting to an external device via electrical or communication for data display and further technical analysis. The detection body 51 may be housed within a receiving groove 3003 and may abut against a spring arm 323. In some embodiments, the detection body 51 may have a third perforation 5001, which is opposite to and communicates with the second perforation 3004 and the first perforation 3002, allowing the puncture needle 40 to extend through the first perforation 3002, the second perforation 3004, and the third perforation 5001 to the side of the detection body 51 near the port. In some embodiments, the detection needle 52 may be disposed within the third perforation 5001 and cooperate with the puncture needle 40.

[0085] Please see Figure 13 , Figure 13 for Figure 1 The schematic diagram of the detection device 100 in the illustrated embodiment is shown in some other embodiments. For example, the housing 10 of the detection device 100 may also include an end cap 101. The end cap 101 can block the opening end 1002 of the main housing 101.

[0086] The end cap 101 and the outer casing 10, such as the main casing 101, can be configured to form a receiving space 1001 to accommodate all structures within the detection device 100, such as the abutment 20, mounting bracket 30, puncture needle 40, and detection assembly 50. The main casing 101 and the end cap 101 can be detachably connected by means well known to those skilled in the art, such as snap-fit, screw-fit, or plug-in, thereby allowing the end cap 101 to be separated from or assembled from the main casing 101. In some embodiments, the end cap 101 can be rotatably engaged with the main casing 101 about a preset rotation axis to achieve a detachable connection. In some embodiments, the end cap 101 may not be part of the casing assembly 200. In some embodiments, the receiving space 1001 may be disposed within the main casing 101.

[0087] End cap 101 may be connected to main housing 101, such as body 11, having accommodating space 1001. Main housing 101, such as body 11, may have an open end 1003 to be connected to end cap 101 at the open end 1003, such that end cap 101 seals open end 1003.

[0088] Please see Figure 14 , Figure 14 for Figure 13The schematic diagram of the end cap 101 in the embodiment shown shows that the inner peripheral wall of the end cap 101 is provided with a tube rib 1011 protruding from the end cap 101. The tube rib 1011 fits against the inner side wall of the main housing 101, such as the body 11, to prevent the end cap 101 from shaking in the horizontal direction relative to the main housing 101, such as the body 11.

[0089] In some embodiments, the upper surface of the pipe rib 1011 is provided with a guide surface 1012 to facilitate the installation of the pipe rib 1011 with the main housing 101, such as the body 11.
