[0048] A specific embodiment of the present disclosure will be described in detail below in conjunction with the accompanying drawings.
[0049] Therefore, the detection device applicator provided by the embodiments of the present disclosure can complete the application of the detection device through simple operation by setting the first locking mechanism and the second locking mechanism which are clamped with each other.
[0050] For the purpose of clear description and easy understanding, in the following description, the side of the detection device in contact with the human body is regarded as the vertical lower side of the detection device applicator, the side of the detection device away from the human body is regarded as the vertical upper side, the direction parallel to the contact surface of the detection device and the human body is regarded as the horizontal direction, the direction along the horizontal direction towards the detection needle of the detection device is regarded as the radial inward direction, and the direction along the horizontal direction away from the center of the detection needle of the detection device is regarded as the radial outward direction. The position description of other related components will also be based on the above description unless otherwise specified. The above description is only used for providing the reference direction for describing the relative position relationship of the structures, and is not a limitation on the actual arrangement of the structures of the embodiments of the present disclosure.
[0051] Referring to FIG. 1 and FIG. 2, FIG. 1 shows an exemplary perspective view of the detection device applicator according to some embodiments of the present disclosure, and FIG. 2 shows an exemplary exploded view of the detection device applicator according to some embodiments of the present disclosure.
[0052] The detection device applicator 100 comprises a housing 10 and an abutting member 20 detachably connected with the housing 10. The housing 10 is movable relative to the abutting member 20. Optionally, the housing 10 is movable relative to the abutting member 20 in a vertical direction. The detection device applicator can be used to hold and lock a detection device assembly, and the abutting member 20 is used to abut against a human body. Optionally, the abutting member 20 can be used to abut against a human body surface to position an application position of a detection device of the detection device assembly. The abutting member 20 is released from holding the detection device by relative movement of the housing 10 and the abutting member 20, and the detection device is placed or implanted into the human body. The detection device applicator further comprises a first elastic locking mechanism 30 and a second elastic locking mechanism 40 releasably connected with the first elastic locking mechanism 30. The detection device can be arranged on the first elastic locking mechanism 30, and the first elastic locking mechanism 30 can be used to move downward in the vertical direction and apply the detection device to the human body, for example. An auxiliary assembly of the detection device can be connected with the second elastic locking mechanism 40, and the second elastic locking mechanism 40 is used to move upward in the vertical direction and remove the auxiliary assembly.
[0053] The first elastic locking mechanism 30 comprises a sending mechanism and a first energy storage member abutting against the sending mechanism, and the second elastic locking mechanism 40 comprises a returning mechanism and a second energy storage member abutting against the returning mechanism. The abutting member 20 is provided with a first locking portion. The sending mechanism is locked by the first locking portion. Optionally, the sending mechanism can be abutted against the first locking portion of the abutting member 20 in the vertical direction, so as to compress the first energy storage member in the vertical direction and be locked in a sending holding position. The sending mechanism comprises a second locking portion. The returning mechanism is locked by the second locking portion. Optionally, the returning mechanism can be abutted against the second locking portion of the sending mechanism in the vertical direction, so as to compress the second energy storage member in the vertical direction and be locked in a returning holding position. The housing 10 further comprises a first trigger portion for releasing the first locking portion and a second trigger portion for releasing the second locking portion. The first energy storage member can drive the sending mechanism to move to a mounting position and mount the detection device, and the second trigger portion releases the second locking portion when the sending mechanism moves to the mounting position of the detection device.
[0054] Optionally, the detection device applicator 100 comprises a shell cover 80 detachably connected with the abutting member 20. The shell cover 80 can be removed relative to the housing 10.
[0055] Optionally, the detection device can be used to analyze a human body analyte to measure a human body index such as a blood glucose level, and the detection device can comprise a detection needle used to be placed into the human body to obtain biological information. The detection device assembly can further comprise an auxiliary assembly connected with the detection device to assist the detection needle to penetrate into the human body.
[0056] Referring to FIGS. 3a-3c, FIG. 3a shows an exemplary cross-sectional view of the detection device applicator according to some embodiments of the present disclosure, in which the first elastic locking mechanism 30 is in the delivery holding position and the second elastic locking mechanism 40 is in the return holding position; FIG. 3b shows a partial enlarged view of section A in FIG. 3a; and FIG. 3c shows a partial enlarged view of section B in FIG. 3a. Optionally, the housing 10 can be generally hollow cylindrical, with an open vertical lower side. The abutment 20 can be generally cylindrical through in the vertical direction, and can be at least partially sleeved with the housing 10 and can move relative to the housing 10 in the vertical direction.
[0057] The delivery mechanism of the first elastic locking mechanism 30 can include a delivery sleeve 31, and the first energy storage member can include a first spring 32 arranged in the vertical direction. The upper end of the first spring 32 can abut against the housing spring support portion of the housing 10, and the lower end thereof can abut against a first spring abutment portion of the delivery sleeve 31, thereby providing a spring thrust in the vertical direction away from the housing 10 to the delivery sleeve 31 in the first direction. The return mechanism of the second elastic locking mechanism 40 can include, for example, a return sleeve 41, and the second energy storage member can include a second spring 42 arranged in the vertical direction, the lower end of the second spring 42 abutting against a second spring abutment portion of the delivery sleeve 31, and the upper end thereof abutting against a return support surface of the return sleeve 41. Thus, the second spring 42 can provide a spring thrust in the vertical direction away from the delivery sleeve 31 to the return sleeve 41.
[0058] Optionally, the abutment 20 can include an abutment inner sleeve 25 partially nested on the radially inner side of the housing 10, and an abutment outer sleeve 29 partially arranged on the outer side of the housing 10. The delivery sleeve 31 can be arranged, for example, on the inner side of the abutment inner sleeve 25, with the outer peripheral portion thereof adjacent to the inner side wall of the abutment inner sleeve 25. The delivery sleeve 31 can include, for example, a generally cylindrical delivery outer sleeve 311, and a delivery platform 313 arranged at the bottom of the delivery outer sleeve 311. The delivery platform 313 can be, for example, a plate-shaped platform extending radially inwardly from the bottom of the delivery outer sleeve 311. In addition, the bottom side of the delivery sleeve 31 can further be provided with a second platform 314 fixedly arranged at the lower end of the delivery platform 313. The second platform 314 can also be generally plate-shaped extending in the horizontal direction. The detection device can be arranged at the lower surface of the second platform 314.
[0059] The abutting outer sleeve 29 can be substantially cylindrical, and its bottom can be fixedly connected with the abutting inner sleeve 25, and its upper side can be provided with two protection side pieces 27 extending upward in the vertical direction, which can be used to cover the opening and other structures formed on the side surface of the shell 10 in the radial direction. In addition, the shell 10 can be provided with a guide groove extending in the vertical direction matched with the protection side piece 27, so that the protection side piece 27 can be circumferentially matched with the guide groove to prevent relative rotation between the abutting piece 20 and the shell 10. An active gap in the vertical and / or radial direction can be provided between the abutting piece 20 and the shell 10. For example, by setting the size of the vertical and radial direction connecting part of the abutting piece 20 and the shell 10, after pressing the shell 10 relative to the abutting piece 20, the abutting parts on the outer side of the two do not directly contact each other, but there is a certain gap. Thus, it is prevented from being clamped to the user's hand during and after the movement.
[0060] Those skilled in the art can understand that, although the above describes a configuration in which the delivery platform 313 of the delivery sleeve 31 is arranged at the bottom of the delivery outer sleeve 311, and the second platform 314 is fixedly connected at the bottom end of the delivery platform 313, the present disclosure does not limit the specific form of the delivery sleeve 31. For example, alternatively, the delivery platform 313 and the delivery outer sleeve 311 can be two separate components, which can be fixedly connected with each other by clamping or the like, thereby reducing the production difficulty. In some other embodiments, the delivery sleeve 31 and the second platform 314 can be integrally formed to obtain higher structural strength. And the delivery platform 313 and the second platform 314 can be arranged at the bottom of the delivery outer sleeve 311 by clamping or the like, or can be arranged to have the same outer diameter as the delivery outer sleeve 311, and be integrally connected to one axial end of the delivery outer sleeve 311 by clamping or bonding. In some other embodiments, the delivery platform 313 can also not be plate-shaped, for example, it can be formed to have a certain curvature or inclination, or be spliced by a plurality of rib plate assemblies.
[0061] The delivery platform 313 of the delivery sleeve 31 can be opposite to an inner top wall of the housing 10 in the vertical direction. Thus, the first spring abutting portion can be disposed on the upper side of the delivery platform 313, and the housing spring support portion can be disposed on the inner top wall of the housing 10. For example, in some embodiments, one end of the first spring 32 in the first direction can directly abut against the inner top wall, and the other end can directly abut against the upper surface of the delivery platform 313. In other embodiments, the first spring abutting portion can include a plurality of platform support ribs 313a extending upward in the vertical direction and disposed on the upper surface of the delivery platform 313, and the upper surfaces of the plurality of platform support ribs 313a can be disposed as a flush surface for abutting against the end surface of the first spring 32. Similarly, the housing spring support portion can also include a plurality of housing support ribs extending downward in the vertical direction, and the lower end surfaces of the plurality of housing support ribs can also be disposed as a flush surface for supporting the end surface of the first spring 32. By disposing the housing support ribs and the platform support ribs 313a, the structural strength of the housing 10 and the delivery platform 313 is enhanced with less material, and the actual length of the spring required to provide elastic pushing force in the vertical direction is shortened, thereby saving costs and reducing the occurrence of spring twisting or jamming due to excessive length.
[0062] In addition, optionally, the first spring abutting portion and the housing spring support portion can also be provided with a spring positioning mechanism for positioning the end portion of the first spring 32. For example, a spring positioning ring, a positioning block, or the like matching the diameter of the spring is disposed on the inner side or the outer side of the spring to avoid displacement of the spring during installation or use.
[0063] Optionally, the return sleeve 41 can be a hollow cylinder with an open downward side, and a horizontal top plate 411 on the upper side. The central part of the delivery platform 313 can be provided with a through hole, and the central part of the second platform 314 can be exposed upward from the through hole. The return support surface can be provided on the lower surface of the top plate 411 of the return sleeve 41, and the second spring abutting portion can be provided on the upper surface of the exposed part of the second platform 314 from the through hole. Both the return support surface and the second spring abutting portion can be provided with a second spring limiting mechanism for limiting the end of the second spring 42. For example, the second spring abutting portion can be provided with a spring limiting ring matched with the inner diameter of the second spring 42, and the lower end of the second spring 42 can be sleeved on the outer side of the spring limiting ring to avoid sliding in the horizontal direction. The lower surface of the top plate 411 of the return sleeve 41 can be provided with a return lock 413 for pulling out the needle, which can be a plurality of protrusions extending downward in the vertical direction. The tips of the extended parts of the return lock 413 can protrude inward in the radial direction, for example, to be fixedly connected with the auxiliary assembly of the detection device assembly by clamping or the like, so as to pull out the auxiliary assembly in the vertical direction when the return sleeve 41 moves relative to the second platform 314 in the vertical direction. The radial outer side of the return lock 413 can also be used as a spring limiting portion for limiting the horizontal position of the second spring 42.
[0064] Optionally, the first locking portion is provided on the side wall of the abutting inner sleeve 25 of the abutting member 20, which can be formed as a spring hook capable of elastically moving in the radial direction, and the first trigger portion can be formed as a housing avoiding hole 101 provided on the housing 10 for avoiding the first locking portion.
[0065] Optionally, the abutting member 20 can be made of plastic material such as polycarbonate, etc. in its entirety, so that the hook structure formed thereby can have certain elastic deformation capability. The first locking portion can for example include an elastic arm 202 separated from the side wall portion of the abutting inner sleeve 25 and extending in vertical direction, the elastic arm 202 including a radial stopper 202a provided at the end of the extending portion of the elastic arm 202, the elastic arm 202 can be used to provide an amount of elastic deformation in radial direction, so that the radial stopper 202a can be moved in radial direction under the driving of radial force. While the housing 10 is arranged at the radial outer side of the radial stopper 202a, the housing 10 can be provided with a housing abutting wall for abutting with the radial stopper 202a in radial direction, and a housing avoiding hole 101 for avoiding the radial stopper 202a in radial direction. The vertical lower end of the radial outer side of the delivery sleeve 31 can be provided with a pushing portion 31a, while the radial inner side of the radial stopper 202a can be provided with a locking driving block 202b for abutting with the pushing portion 31a, the locking driving block 202b can for example be provided with an upward driving slope 202c, the driving slope 202c being in contact with the pushing portion 31a and being used to slide obliquely with the pushing portion 31a in vertical direction when being abutted thereby, so as to drive the elastic arm 202 to elastically deform, and make the radial stopper 202a abut outward in radial direction.
[0066] It can be understood by those skilled in the art that, although the above describes a setting that the radial stopper 202a is made to extend outward in radial direction by the spring elastic force of the first spring 32 and the cooperation of the pushing portion 31a with the locking driving block 202b having the driving slope 202c, the present disclosure does not limit the unlocking mode of the first locking portion.
[0067] The structures not introduced in FIG. 3a and FIG. 3b are the same as the corresponding structures in FIG. 1 and FIG. 2, and will not be described here again.
[0068] FIG. 4 shows an exemplary cross-sectional view of a detection device applicator according to some embodiments of the present disclosure. Optionally, the general structure of the detection device applicator 400 can be similar to the detection device applicator 100 in some embodiments of the present disclosure. For example, the general structure of the detection device applicator 400 is similar to the detection device applicator 100 in FIG. 1, FIG. 2, FIG. 3a, and FIG. 3b.
[0069] Referring to FIG. 4, the detection device applicator 400 can include a housing 410, an abutting member 420 coupled to the housing 410, and a cover 480 detachably coupled to the abutting member 420. The cover 480 can be removed with respect to the housing 410, and the housing 410 can move in a vertical direction with respect to the abutting member 420. The detection device applicator 400 can be used to hold and lock a detection device assembly, and the abutting member 420 can be used to abut a human body surface to position an application position of a detection device of the detection device assembly, for example, and to release the holding of the detection device by moving the abutting member 420 with respect to the housing 410 to place the detection device on the human body.
[0070] The detection device applicator 400 can include elastic arms 422 provided on a side wall of the abutting member 420. When the housing 410 is pressed downward with respect to the abutting member 420, a lock driving block 422b protruding radially inward at an end of the elastic arm 422 can be pushed by a pushing portion 431a of a bottom of a sending sleeve 431. One or both of the lock driving block 422b and the pushing portion 431a can be provided with a driving slope, and the lock driving block 422b and the pushing portion 431a can be in contact with each other via the driving slope. The pushing portion 431a can elastically deform the elastic arm 422 radially outward, and the elastic arm 422 can extend into a housing avoiding hole 401 provided on a side wall of the housing 410. Unlike the detection device applicator of the above-described embodiment of the disclosure, the elastic arm 422 can not be provided with a radial blocking block protruding radially outward, but can be elastically deformed outward to extend into the housing avoiding hole 401 via the lock driving block 422b on an inner side of the elastic arm 422 and the pushing portion 431a. Thus, the structure of the detection device applicator can be simpler, and the layout in the radial direction can be more compact.
[0071] Optionally, the radial blocking block 202a can be made of an elastic material, so that the radial blocking block 202a can extend into the housing avoiding hole 101 by elastic deformation of the radial blocking block 202a itself. In addition, optionally, two housing avoiding holes 101 that are symmetrical to each other can be provided on the housing 10, and two elastic arms 202 that are symmetrical to each other can be provided on the lower inner sleeve of the abutting member 20. More housing avoiding holes 101 and elastic arms 202 can be provided to provide a more stable locking force. By providing the housing avoiding hole 101 and the corresponding radial blocking block 202a, the unlocking of the first elastic locking mechanism 30 can be automatically achieved by the spring force of the first spring 32, and the user can avoid using a large pushing force to press the detection device applicator, which can cause unnecessary operation difficulty and discomfort.
[0072] Thus, when the radial block 202a abuts against the housing abutting wall on its outer side, the delivery sleeve 31 of the first elastic locking mechanism 30 cannot drive the elastic hook to move radially outward. At this time, the locking driving block 202b on the radial inner side of the elastic hook abuts against the delivery sleeve 31 in the vertical direction by means of the driving slope 202c thereof, so as to compress the first spring 32 and keep the delivery sleeve 31 in the delivery holding position. At this time, by setting the distance between the end surface of the abutting member 20 for abutting against the human body and the delivery holding position, the detection device can be completely accommodated in the housing 10 and the abutting member 20 in the axial direction, so as to avoid that the detection device is touched by mistake by the user or is polluted by the external environment.
[0073] Optionally, the circumferential outer side of the delivery sleeve 31 can also be provided with a check groove 31b, which can be, for example, a groove recessed in the radial direction on the outer wall of the delivery sleeve 31 and extending in the vertical direction for a distance, and the lower end of the extension direction of the check groove 31b is provided with an upward check surface 31c. The check groove 31b is used to at least partially accommodate the locking driving block 202b which bounces back in the radial direction after the delivery sleeve 31 is completely ejected. When the delivery sleeve 31 is pushed upward in the vertical direction, the check surface 31c will abut against the lower end surface of the locking driving block 202b, so as to prevent the delivery sleeve 31 from moving reversely, and further, the abutment between the bottom end of the elastic arm 202 and the bottom surface of the avoiding hole 101 of the housing can also prevent the housing 10 from bouncing back. Thus, it can be prevented that the user accidentally presses the delivery mechanism to expose the puncture needle after use, which causes the user to contact the puncture needle and causes danger. In some embodiments, the check surface 31c can also be provided on the upper end surface of the delivery sleeve 31 in the vertical direction, and in this case, the check groove 31b is not needed.
[0074] In addition, optionally, the inner wall of the abutting inner sleeve 25 can also be provided with a limiting block which protrudes in the radial direction inwardly, and the delivery sleeve 31 can be provided with a limiting block groove corresponding to the limiting block. The limiting block includes an upward limiting block surface, which is used to abut against a downward end surface of the limiting block groove in the vertical direction when the delivery sleeve 31 is extended, so as to limit the extension distance of the delivery sleeve 31. In some embodiments, the limiting block can also play a circumferential limiting role, that is, the limiting block and the limiting block groove are matched to prevent the abutting member 20 and the delivery sleeve 31 from rotating relative to each other. In some embodiments, the inner wall of the abutting inner sleeve 25 is provided with a limiting guide groove, and the outer wall of the delivery sleeve 31 is provided with a limiting guide block corresponding to the limiting guide groove. The limiting guide groove and the limiting guide block can be matched to limit and guide the delivery sleeve 31 in the vertical direction.
[0075] Optionally, the second trigger portion can be formed as a trigger cylinder 107 extending downward in the vertical direction from an inner top wall of the housing 10, and the second locking portion can be one or more elastic locking hooks 313b extending upward from an upper surface of the delivery platform 313. The one or more elastic locking hooks 313b can be arranged at intervals from each other at an angle, for example, each of the elastic locking hooks 313b can include an elastic hook body 313c extending upward in the vertical direction and a hook head 313d protruding radially inward from the elastic hook body 313c, and the elastic hook body 313c can be elastically movable in the radial direction under the action of a radial force. The one or more elastic locking hooks 313b can be enclosed around the outer periphery of the return sleeve 41 of the return mechanism, and the plurality of elastic locking hooks 313b can collectively abut against the upper end of the return sleeve 41 in the vertical direction. In some embodiments, the hook head 313d of the elastic locking hook 313b can include a downward hook head slope 313e, and the upper end of the return sleeve 41 can be provided with an unlocking slope 414 corresponding to the hook head slope 313e, for example, the unlocking slope 414 can be a chamfer formed on the outer periphery of the upper end of the return sleeve 41. The unlocking slope 414 can be used to abut against the hook head slope 313e to convert the upward pushing force of the second spring 42 into an outward radial force through the action between the slopes.
[0076] The trigger cylinder 107 can be sleeved on the radially outer side of the one or more elastic locking hooks 313b, and the radially inner wall thereof can be used to abut against the elastic hook body 313c in the radial direction, so that the elastic hook body 313c cannot be elastically deformed under the spring force of the second spring 42 and drive the hook head 313d to elastically move radially outward. Thus, the one or more elastic locking hooks 313b can be used to lock the return mechanism in the vertical direction, so that the second spring 42 remains in a compressed state to lock the return mechanism in the return holding position.
[0077] Optionally, by setting the axial arrangement positions of the first trigger portion and the second trigger portion on the housing 10, the single action of the housing 10 can trigger the unlocking of the first elastic locking mechanism 30, and after the second elastic locking mechanism 40 moves to the detection device mounting position, the unlocking of the second elastic locking mechanism 40 can be automatically triggered.
[0078] Figure 5 shows an exemplary cross-sectional view of the applicator of the detection device according to some embodiments of the present disclosure. Referring to Figure 5, the first trigger portion is formed as a housing escape hole 101 for avoiding the radial block 202a, while the second trigger portion is a trigger cylinder 107 for limiting the elastic locking hook 313b. Then, when the first elastic locking mechanism 30 and the second elastic locking mechanism 40 are in the sending holding position and the returning holding position, the first distance between the lower end surface of the housing escape hole 101 in the vertical direction and the lower end surface of the radial block 202a is D1, the second distance between the lower edge of the inner wall of the trigger cylinder 107 and the top end of the radial outer wall of the elastic locking hook 313b is D2, and the third distance between the initial position of the detection device and the detection device installation position is D3. In actual use, when the abutting member 20 is abutted against the human skin 300 and the detection device is installed, the pressed part of the human skin 300 will be pressed into the abutting member due to the elasticity of the skin, so the value of the third distance D3 can be smaller than the distance between the lower bottom surface of the detection device and the lower bottom surface of the abutting member 20 in the initial position.
[0079] At this time, if the sum of the first distance D1 and the second distance D2 is set to be comparable to or smaller than the third distance D3, it can be ensured that after the first elastic locking mechanism 30 is released by driving the housing 10 to move relative to the abutting member 20 by the first distance D1, the sending mechanism drives the detection device to continue to move under the spring force of the first spring 32, so that the detection device as a whole moves from the initial position by the third distance D3 to install the detection device to the human body. At this time, the third distance D3 makes the relative movement distance between the sending mechanism and the housing 10 be the third distance D3 minus the first distance D1, so if the relative movement distance is greater than or equal to the second distance D2, the second elastic locking mechanism 40 can be automatically released.
[0080] Optionally, the first distance D1 described above can be set to 4±1mm, for example, so that the pressing action during installation of the detection device can trigger more easily, but it will not be accidentally released due to disturbance.
[0081] Optionally, the first spring 32 can be arranged at the circumferential outside of the second spring 42. Specifically, the inner diameter size of the first spring 32 can be greater than the outer diameter size of the return sleeve 41, so that the second elastic locking mechanism 40 can be arranged integrally at the radial inside of the first spring 32. In addition, the axial positions of the first spring 32 and the second spring 42 can be arranged in alignment with the center of the auxiliary assembly. In this way, not only the spring elastic force acting positions of the first spring 32 and the second spring 42 can be arranged concentrically, but also the pushing pressure of the first spring 32 on the detection device and the returning tension of the second spring 42 can be aligned with the center of the auxiliary assembly. Therefore, no matter when the detection device is applied or the auxiliary assembly is pulled out, the force direction of the auxiliary assembly is consistent with the force applying direction, which reduces the situation that the detection needle deviates in the direction of insertion or pulling out due to the force deviation. In addition, the lower end of the first spring 32 can be arranged on the upper surface of the sending platform 313, and the lower end of the second spring 42 can be arranged on the upper surface of the second platform 314 fixedly connected with the sending platform 313, so that the overall structure is simpler and the layout is more compact. In some embodiments, the sending platform 313 and the second platform 314 can be formed integrally, so as to further simplify the structure of the device and improve the structural strength.
[0082] Those skilled in the art can understand that, although the above describes a structure in which the first spring 32 is sleeved outside the trigger cylinder 107 and the second elastic locking mechanism 40 is arranged inside the first spring 32, the present disclosure does not limit the specific arrangement manner of the first elastic locking mechanism 30 and the second elastic locking mechanism 40. For example, the first spring 32 and the second spring 42 can be arranged in a horizontal direction with a spacing, or a plurality of first springs 32 can be arranged at a certain angle with a spacing, or a plurality of first springs 32 can be arranged outside the second spring 42, etc. As long as the first elastic locking mechanism 30 and the second elastic locking mechanism 40 can independently act without interfering with each other, it is acceptable. In addition, in some embodiments, the elastic force of the first spring 32 and the second spring 42 can be sized so as to be able to overcome the locking resistance of the corresponding first elastic locking mechanism 30 or second elastic locking mechanism 40. In some embodiments, a spring support portion can be arranged to reduce the total length required by the first spring 32 and / or the second spring 42, for example, a support rib plate can be arranged at the top side and / or the bottom side of the first spring 32 and / or the second spring 42. In this way, the length of the spring can be reduced, which is beneficial to eliminate the generation of undesirable radial force caused by the twisting and deflection of the spring due to the excessive length of the spring during use. In addition, the first spring 32 or the second spring 42 with smaller wire diameter and lower pressure can be used. At this time, the axial deformation of the first spring 32 or the second spring 42 is easier, and it is easier to operate.
[0083] The structures not introduced in FIG. 5 are the same as the corresponding structures in FIGS. 1 to 3b, and will not be described here again.
[0084] FIG. 6 shows an exemplary perspective view of a shell cover of the detection device applicator according to some embodiments of the present disclosure; and FIG. 7 shows an exemplary perspective view of an abutment of the detection device applicator according to some embodiments of the present disclosure. Referring to FIG. 6 and FIG. 7, the shell cover 80 can include a horizontal bottom wall, and a concentrically arranged inner cylinder 82 and outer cylinder 81 extending upwardly from the bottom wall. The inner cylinder 82 can have a vertical extension height higher than the outer cylinder 81, and a locking block 83 can be arranged between the inner cylinder 82 and the outer cylinder 81 and extending radially outwardly from the side wall of the inner cylinder 82. The shell cover 80 can be fastened to the bottom surface of the abutment 20 from bottom to top, with the inner cylinder 82 being arranged to abut the inner side surface of the abutment 20 in the radial direction, and the upper end surface of the outer cylinder 81 being arranged to abut the bottom end surface of the abutment. With the inner cylinder 82 and the outer cylinder 81 being connected to the abutment 20 separately, the sealing performance of the shell cover 80 to the inside of the detection device applicator is improved. By arranging the inner cylinder 82 to be higher than the outer cylinder 81, the rotation direction can be guided when the shell cover 80 and the abutment 20 rotate relative to each other, so that tilting during rotation is avoided, while the installation and removal are facilitated.
[0085] The locking block 83 can be arranged to extend into the locking slot 261 arranged on the bottom surface of the abutment 20, and to be screwed into the locking positioning slot 262 arranged on the bottom of the abutment 20 by the relative rotation between the shell cover 80 and the abutment 20, so as to be locked relative to the abutment 20 in the vertical direction. In some embodiments, the upper end surface of the locking block 83 can also be arranged to abut the lower end surface of the shell 10 in the vertical direction after being screwed into the locking positioning slot 262, so as to prevent the relative movement between the shell 10 and the abutment 20 in the vertical direction in the capped state.
[0086] Optionally, a protection assembly can be arranged on the lower side of the detection device, for example, on the vertical lower side of the detection device, which can be rotationally coupled with the auxiliary assembly. The protection assembly can include a hollow protection shell in a substantially columnar shape, which can be open upwardly, and the open end surface thereof can be provided with a joint for rotationally coupling with the auxiliary assembly. The shell cover 80 can be further provided with a protection assembly locking portion for installing or removing the protection assembly, which can include at least two lateral clamping hooks 84. The two lateral clamping hooks 84 can include a clamping hook body 84a extending upwardly from the central portion of the bottom surface of the shell cover 80, and the top end of the extending portion of the clamping hook body 84a can be provided with a clamping hook portion 84b protruding radially inwardly, and the radially inward end surface of the clamping hook portion 84b can be arranged to abut the side surface of the protection shell. The radially inward end surface of the clamping hook portion 84b can be arranged to match the shape of the radially outer peripheral surface of the protection shell, so as to better position the protection shell.
[0087] Optionally, the circumferential side portion of the protective shell is further provided with a positioning flat surface extending in the radial direction, which can abut against the positioning side surface 84d of the hook portion 84b, so that the protective shell can be clamped by the hook portion 84b in the form of at least one-directional anti-rotation. It can be understood by those skilled in the art that although the above describes a positioning flat surface extending in the radial direction of the circumferential side surface of the protective shell, the present disclosure does not limit the form of the positioning structure on the outer side of the protective shell. For example, in some embodiments, the positioning flat surface can also be arranged to form a certain angle with the radial direction, for example, it can be inclined towards the circumferential outer surface of the protective shell. Correspondingly, the positioning side surface 84d of the hook portion 84b of the shell cover 80 can also form a certain angle with the radial direction, and the inclination angles of the positioning flat surface and the positioning side surface 84d can match each other. Thus, for example, when the positioning side surface 84d of the hook portion 84b is rotationally matched with the positioning flat surface, the lateral corner of the hook portion 84b can be at least partially rotationally shifted into the corner space formed by the positioning flat surface and the other side portion of the protective shell, and form a ratchet pawl type engagement therewith. Thus, the positioning side surface 84d and the positioning flat surface can form a self-locking to prevent the lateral hook 84 from deforming and disengaging when subjected to too much force.
[0088] The monitoring device applicator according to some embodiments of the present disclosure can efficiently and quickly complete the application of the detection device by means of the first elastic locking mechanism 30 and the second elastic locking mechanism 40 triggered by the action thereof, thereby reducing the risk of medical accidents caused by improper use of the patient.
[0089] The other structures included in FIGS. 6 and 7 are the same as the corresponding structures in FIGS. 1 to 3b and FIG. 5, and will not be described again here.
[0090] FIG. 8 shows an exemplary cross-sectional view of a detection system according to some embodiments of the present disclosure. Referring to FIG. 8, the detection system 200 includes a detection device applicator 100 according to some embodiments of the present disclosure and a detection device assembly 70. For example, the detection device applicator 100 in the detection system 20 can be the detection device applicator 100 or 400 in the foregoing FIGS. 1 to 7.
[0091] The detection device assembly 70 may, for example, include a detection device 71, an auxiliary assembly 72 disposed above the detection device 71, and a protective assembly 73 disposed below the detection device 71. Optionally, the detection device assembly 70 can include a detection device 71 according to various embodiments of the present disclosure. The detection device 71 may, for example, be an electronic device for mounting on a human body and detecting various analytes of the human body, such as, for example, detecting and analyzing tissue fluid and the like of the human body to collect indicators including, but not limited to, glucose, blood sugar, acetylcholine, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormone, hormones, ketones (e.g., ketone bodies), lactate, oxygen, peroxide, prostate specific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin, and the like. The concentration of drugs such as, but not limited to, antibiotics (e.g., gentamicin, vancomycin, and the like), digitalis glycosides, digoxin, drugs of abuse, theophylline, and warfarin, and the like can also be determined. The detection device 71 may, for example, include a housing and an electronic assembly, wherein the electronic assembly may, for example, be disposed inside the housing. The housing can have a housing bore extending through the housing in a vertical direction, and the electronic assembly can include a detection needle extending downwardly in the vertical direction and protruding out of the housing. The detection needle may, for example, be used to extend into the human body to detect corresponding physiological indicators in the human body.
[0092] FIG. 9 illustrates an exemplary exploded view of a detection device assembly of a detection system according to some embodiments of the present disclosure. Optionally, the detection device assembly of FIG. 9 is the detection device assembly of FIG. 8. Referring to FIG. 9, the detection device assembly 70 can further include an auxiliary needle assembly, which can include an auxiliary assembly 72 and a protective assembly 73 according to various embodiments of the present disclosure. The auxiliary assembly 72 can be disposed on an upper side of the housing in a vertical direction, and the protective assembly 73 can include a protective shell disposed on a lower side of the housing. The auxiliary assembly 72 may, for example, include a piercing needle for assisting the detection needle to pierce into the human body. The protective assembly 73 can be used to surround and seal the piercing needle and the detection needle to protect them from environmental contamination. The auxiliary assembly 72 and the protective assembly 73 can be engaged within the housing bore of the housing and can be rotatable relative to each other to a locked position or an unlocked position. In the locked position, the auxiliary assembly 72 and the protective assembly 73 are vertically limited by the housing.
[0093] Optionally, the auxiliary assembly 72 comprises a substantially cylindrical needle holder, one axial end of which is fixedly connected with the puncture needle, and the other axial end can be provided with a needle locking groove formed by inwardly recessing in the radial direction, which is used for clamping with the sharp end portion of the return locking buckle 413 of the return sleeve 41, so that when the return sleeve 41 moves away from the delivery platform 313 in the radial direction, the auxiliary assembly 72 can be pulled out relative to the detection device 71. In some embodiments, when the auxiliary assembly 72 is locked relative to the protection assembly 73, the lower end surface of the needle holder is flush with the lower end surface of the detection device 71, or is recessed inwardly relative to the lower end surface, so that the needle holder does not hinder the insertion of the puncture needle when the detection device assembly is applied to the human body, and there is no need to pull out the needle in advance.
[0094] The other structures included in FIG. 9 are the same as the corresponding structures in FIGS. 1-8, and will not be described again here.
[0095] The working process of the detection system will be described below in conjunction with the accompanying drawings.
[0096] FIG. 10 shows an exemplary cross-sectional view of the detection system of some embodiments of the disclosure, in which the detection system is in an initial state. Referring to FIG. 10, when the detection system is not in use, the detection device 71 of the detection device assembly 70 is located on the lower side of the second platform 314 of the first elastic locking mechanism 30, the needle holder of the auxiliary assembly 72 is clamped and locked by the return locking buckle 413 of the return sleeve 41 on the upper side of the second platform 314, the protection shell of the protection assembly 73 is clamped by the lateral clamping hook 84 of the shell cover 80 on the lower side of the detection device 71, and the protection shell is in relative engagement with the needle holder on the inside of the shell hole of the detection device 71, and is locked in the vertical direction. The delivery mechanism of the detection device applicator is locked in the delivery holding position by the first locking portion of the abutting piece 20, and the return mechanism of the detection device applicator is locked in the return holding position by the second locking portion of the abutting piece 20. At this time, the first spring 32 can be compressed to provide a spring pressure for pressing the delivery sleeve 31 in the vertical direction, but at this time it can only be partially compressed, so that it can be kept in an incompletely compressed state before the detection system is not in use, avoiding creep for a long time in a high compression state.
[0097] Figure 11 shows an exemplary cross-sectional view of the detection system of some embodiments of the present disclosure, in which the protective shell is unlocked and removed from the needle holder after the rotation of the shell cover 80. Referring to Figure 11, after the shell cover 80 is rotated relative to the abutting piece 20, the locking block 83 of the shell cover 80 moves along the locking positioning groove 262 at the bottom of the abutting piece 20 and is finally able to align with the locking clamping groove 261 at the bottom of the abutting piece 20 and move out in the vertical direction. At the same time, the positioning side surface 84d of the lateral clamping hook 84 of the shell cover 80 can abut the positioning plane of the protective shell, so that the protective shell rotates with the shell cover 80 until it is rotated to an unlocked position relative to the auxiliary assembly 72, at which time the protective shell can be moved out in the vertical direction relative to the auxiliary assembly 72. The hooking part 84b of the lateral clamping hook 84 of the shell cover 80 can ensure that the protective shell remains vertical during rotation by cooperating with the shape of the side surface of the protective seat, reducing the risk of the rotation being blocked due to the inclination of the protective shell.
[0098] Figure 12 shows an exemplary cross-sectional view of the detection system of some embodiments of the present disclosure, in which the first elastic locking mechanism 30 is unlocked after the shell body 10 is pressed relative to the abutting piece 20. Referring to Figure 12, after the shell cover 80 is removed, the lower surface of the applicator abutting piece 20 can be contacted with the target position on the human body intended for placing the detection device 71, and the shell body 10 can be pressed relative to the abutting piece 20. At this time, the shell body 10 moves downward relative to the abutting piece 20, and the shell body avoiding hole 101 of the shell body 10 moves to align with the radial block 202a of the abutting piece 20, and the radial block 202a extends into the shell body avoiding hole 101 in the radial direction under the pushing of the pushing part 31a of the delivery sleeve 31 inside the radial block 202a, so that the locking driving block 202b on the radial inner side of the abutting piece 20 moves to the radial outer side to avoid the delivery sleeve 31, so that the delivery sleeve 31 can move downward in the vertical direction.
[0099] By setting the shell body 10 to be movable relative to the abutting piece 20 towards the application direction of the detection device 71, and placing the detection device 71, the user can press in the direction opposite to the position of the skin of the human body to be measured during use, so that the application operation is more simple and direct. At the same time, since the shell body 10 can be set to be exposed on the side away from the skin of the human body to be measured relative to the abutting piece 20, it can be stably held by the user as a handle, facilitating the user to apply force.
[0100] Figure 13 shows an exemplary cross-sectional view of the detection system of some embodiments of the present disclosure, showing the state when the second elastic locking mechanism 40 is unlocked after the delivery sleeve 31 is extended. Referring to Figure 13, after the first elastic locking mechanism is unlocked, the delivery sleeve 31 is pushed downward in the vertical direction by the spring force of the first spring 32 to push the detection device 71, so that the auxiliary detection needle of the puncture needle is inserted into the human body, and the lower surface of the detection device 71 is in contact with the human body. When the detection device 71 is moved in the vertical direction to the installation position of the detection device 71, the top end of the outer side surface of the plurality of elastic locking hooks 313b on the delivery platform 313 is out of contact with the side wall of the trigger cylinder 107. So that the plurality of elastic locking hooks 313b can be deformed and moved radially outward by the spring force of the second spring 42 by the contact of the hook head inclined surface 313e thereof with the unlocking inclined surface 414 of the return sleeve 41, thereby releasing the return sleeve 41 in the vertical direction.
[0101] Figure 14 shows an exemplary cross-sectional view of the detection system of some embodiments of the present disclosure, showing the state after the detection device 71 is returned. Referring to Figure 14, after the second elastic locking mechanism 40 is released, the return sleeve 41 and the auxiliary assembly 72 fixedly connected thereto are moved upward in the vertical direction by the pushing of the second spring 42, thereby pulling the puncture needle out of the human body. The return sleeve 41 can continue to move so that the tip of the puncture needle is completely retracted into the upper side of the second platform 314, so that the puncture needle is not exposed. At this time, the check surface 31c provided on the delivery sleeve 31 can be in abutment with the lower end surface of the locking driving block 202b on the abutment piece 20, thereby preventing the delivery sleeve 31 from rebounding after the applicator is used, avoiding the user from accidentally pressing the delivery sleeve 31 upward after using the applicator, so that the puncture needle is exposed, causing the user to be pricked by the needle tip. In some embodiments, an upward check bottom surface 101a can also be provided on the lower side of the shell avoiding hole 101. After the elastic arm 202 moves to the shell avoiding hole 101 to release the delivery mechanism, when the radially inner side of the elastic arm 202 is pushed outward in the radial direction by the delivery mechanism and extends into the shell avoiding hole 101, the check bottom surface 101a is used to abut against the bottom end of the radial blocking block 202a of the elastic arm 202, so as to prevent the shell 10 from moving in the reverse direction. Thus, the user can be prompted that the detection system has been used, avoiding confusion with unused detection systems.
[0102] The detection system in Figures 10-14 can be the detection system in the foregoing Figure 8. The other structures included in Figures 10-14 are the same as the corresponding structures in Figure 8, which will not be described again here.
[0103] Therefore, the detection system according to some embodiments of the present disclosure can complete automatic application of the detection device. When the detection device needs to be inserted into the human body by means of a needle or the like, the detection system with the automatic application function can reduce the psychological pressure and actual pain of the user and can avoid problems such as insufficient needle insertion depth or skewing due to improper operation, thereby improving the installation success rate of the detection device.
