Description

Technical Field

[0001] The present disclosure generally relates to the field of medical device technology. More specifically, the present disclosure relates to a screw-out reminder mechanism and an application device. Background Art

[0002] In the current field of medical testing equipment, it is common to use physiological information detectors applied to the human body. Such detectors obtain information on human physiological indicators, such as blood sugar levels, through probes placed in the human body, and use their internal electronic components to process the information accordingly before sending it to an external receiving device. When using a detector application device to apply the detector to the human body, the shell cover of the applicator needs to be opened to expose the needle to facilitate subsequent application operations. However, when the user twists the shell cover, since they cannot know whether the shell cover has been twisted to the open position, they may twist the shell cover back, resulting in damage to the shell cover or the detector, or damage to the structure of the applicator.

[0003] In view of this, there is an urgent need to provide a screw-out reminder mechanism and an application device to remind the user that the shell cover has been screwed into place and can be pushed out and separated. Utility Model Content

[0004] In order to at least solve one or more technical problems mentioned above, the present disclosure proposes a screw-out reminder mechanism and an application device in multiple aspects.

[0005] In a first aspect, the present disclosure provides an unscrewing reminder mechanism, characterized in that it includes: a shell and a shell cover locked with the shell along a first direction, wherein the shell cover can be separated from the shell along the first direction after being screwed relative to the shell; a ramp section is provided at the bottom of the shell, and an upwardly protruding positioning piece is provided at the axial end of the upper part of the shell cover, wherein when the shell cover is screwed through the ramp section, the ramp section pushes the positioning piece along the first direction, which is used to prompt the shell cover to be separated along the first direction after being screwed.

[0006] In some embodiments, the housing includes an upper housing and a lower housing that are interlocked, wherein the slope section is disposed at the bottom end of the upper housing.

[0007] In some embodiments, the positioning member includes a locking groove extending in the radial direction, and the housing includes a locking flange protruding radially inward, and the locking flange cooperates with the locking groove to lock the housing cover in the first direction.

[0008] In some embodiments, the housing includes an upper housing and a lower housing that are interlocked, wherein a locking flange is disposed at a bottom end of the lower housing.

[0009] In some embodiments, the locking flange also has a release port that passes through the axial direction, and the release port is located at the lower end of the ramp section. During the movement of the positioning member toward the release port, the ramp section pushes the positioning member in the first direction, and finally pushes the positioning member downward from the release port in the first direction, so as to prompt the shell cover to be separated in the first direction after screwing.

[0010] In some embodiments, the locking flange further includes a limiting segment extending away from the shell cover along the first direction, and the limiting segment includes a stop surface.

[0011] In some embodiments, the shell further includes a stop side wall, and a locking section is provided between the stop side wall and the stop surface, wherein when the shell cover and the shell are locked, the positioning member is located in the locking section.

[0012] In some embodiments, the locking section has a thickness along the first direction that is greater than that of other sections of the locking flange except the limiting section.

[0013] In some embodiments, the thickness of the locking flange along the first direction is arranged to be thicker first and then thinner toward the screwing-out position along the direction of relative rotation between the housing and the shell cover.

[0014] In a second aspect, the present disclosure provides an application device comprising the above-mentioned screw-out reminder mechanism.

[0015] Through the unscrewing reminder mechanism provided above, the embodiment of the present disclosure can remind the user to separate the shell cover along the first direction after unscrewing the shell cover by providing a slope section that can abut against the positioning member along the first direction.

[0026] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 , Figure 1An exploded schematic diagram of an application device with a screw-out reminder mechanism according to some embodiments of the present disclosure is shown. In some embodiments of the present disclosure, an application device 100 is provided. The application device 100 may be a medical device for attaching a detection device to a human body, and may include a screw-out reminder device for reminding the user that the screw-out is in place when the shell cover is screwed out. The screw-out reminder device may, for example, include a housing 10 and a shell cover 102 locked with the housing 10 in a first direction, wherein the shell cover 102 can be separated from the housing 10 in the first direction after being screwed relative to the housing 10. The lower portion of the housing 10 may be provided with a ramp section 103 protruding in the first direction toward the shell cover, and the upper axial end of the shell cover 102 may be provided with an upwardly protruding positioning member 104. When the shell cover 102 is screwed past the ramp section 103, the ramp section 103 pushes the positioning member 104 in the first direction to prompt the user to separate the shell cover 102 in the first direction after being screwed out.

[0028] Specifically, in some embodiments, the housing 10 may include, for example, an upper housing 120 and a lower housing 130, wherein both the upper housing 120 and the lower housing 130 may be formed as hollow structures, and the upper housing 120 and the lower housing 130 may be nested with each other along a first direction to form the housing. The upper housing 120 and the lower housing 130 may be formed as a generally cylindrical shape, and the first direction may be the axial direction of the housing 10, and the side thereof facing the housing cover 102 may be considered the lower side of the housing 10.

[0029] In some embodiments, the ramp section 103 is formed along the lower end surface of the upper housing 120 and protrudes toward the housing cover 102. For example, when the housing cover 102 is fastened to the housing in a first direction, the lower end of the upper housing 120 can be located radially inward of the lower housing 130, so that the ramp section 103 can be downwardly pressed against the positioning member 104 provided on the housing cover 102 in the first direction when the housing cover 102 rotates relative to the housing.

[0030] According to this arrangement, when the user screws on the housing cover 102, driving the positioning member 104 in the screwing direction, the upper surface of the positioning member 104 contacts the axial end surface of the ramp section 103. The positioning member 104 then slides relative to the ramp section 103 along the inclined end surface of the ramp section 103. During the relative sliding process, the height of the ramp section 103 gradually increases in the axial direction, thereby gradually pushing the positioning member 104 downward in the first direction, causing the positioning member 104 to be pushed downward in the first direction, thereby prompting the user to separate the housing cover 102 in the first direction.

[0031] In some embodiments, the relative positions of the ramp section 103 and the positioning member 104 can be set so that when the housing cover 102 is in the open position, the highest point of the ramp section 103 is aligned with the positioning member 104. According to this arrangement, when the positioning member 104 is screwed to the edge of the open position, the pressing force of the ramp section 103 along the first direction reaches its maximum, so that the user can clearly feel the positioning member 103 protruding in the first direction, thereby ensuring that the user receives the prompt to separate the housing cover 102 in the first direction after screwing.

[0032] In some embodiments, the open position may be a position where the housing cover 102 can be screwed to a maximum opening, and the housing cover 102 cannot be screwed forward any further in the open position.

[0033] In some embodiments of the present disclosure, see Figure 3 , Figure 3 yes Figure 1 A partial enlarged schematic diagram of section A in the middle. A downwardly angled protruding flange is provided on the axially outer side of ramp section 103. With this arrangement, when cover 102 is in the open position, the downwardly angled protruding flange of ramp section 103 abuts the upper end surface of positioning member 104 in the first direction, causing positioning member 104 to visibly protrude in the first direction. This allows the user to clearly perceive the positioning member 103 protruding in the first direction, ensuring that the user receives the prompt to separate cover 102 in the first direction after twisting.

[0034] See also Figure 1 and Figure 5 , Figure 5 An exemplary stereoscopic view of a shell cover of an application device having an unscrewing reminder mechanism according to some embodiments of the present disclosure is shown. In some embodiments of the present disclosure, the positioning member 104 includes a locking groove 105 extending in the radial direction. The housing 10 includes a locking flange 106 protruding radially inward, and the locking flange 106 cooperates with the locking groove 105 to lock the shell cover 102 in a first direction. Specifically, the positioning member 104 can be configured to protrude in the axial direction of the shell cover 102 toward the housing 10, for example, and can be configured to be located radially outside the shell cover 102. A locking groove 105 can be provided radially outside the positioning member 104 and recessed radially into the outer side surface of the positioning member 104. Correspondingly, a locking flange 106 that protrudes radially inward can be provided on the lower end surface of the lower shell 130 of the housing 10. The locking flange 106 can be configured to cooperate with the locking groove 105, so that after the housing cover 102 is engaged with the housing 10, the locking flange 106 can be at least partially accommodated in the locking groove 105. When the housing cover 102 is locked relative to the housing 10, the inner top wall of the locking groove 105 can, for example, abut against the upper surface of the locking flange 106, thereby locking the housing cover 102 relative to the housing 10 in the first direction.

[0035] In some embodiments of the present disclosure, Figure 1 As shown in FIG, the locking flange 106 further has an axially extending release opening 107. The shape and position of the release opening 107 match those of the positioning member 104, so that the positioning member 104 can extend into the interior of the housing 10 through the release opening 107 in a first direction and further rotate relative to the housing 10, causing the locking groove 105 of the positioning member 104 to rotate in the direction of relative rotation between the two until it is sleeved on the locking flange 106. In this way, the housing cover 102 can be locked relative to the housing 10 in a simple manner.

[0036] In some embodiments, the release opening 107 can be positioned at the lower end of the ramp section 103. When the housing cover 102 begins to be screwed, the positioning member 104 will synchronously move on the locking flange 106. During the movement of the positioning member 104 toward the release opening 107, the ramp section 103 will abut against the upper end surface of the positioning member 104 in the first direction, and eventually push the positioning member 104 downward from the release opening 107 in the first direction, thereby further prompting the housing cover 102 to be separated in the first direction after screwing.

[0037] In some embodiments, the height of the slope section 103 can be set so that the positioning member 104 obviously protrudes downward in the first direction when it contacts the slope section 103 , so as to prompt the shell cover 102 to be separated in the first direction after being screwed.

[0038] In some embodiments of the present disclosure, see Figure 4 , Figure 4 yes Figure 1 A partial enlarged schematic diagram of portion B in FIG. The locking flange 106 may include multiple sections arranged sequentially along the rotational direction of the positioning member 104 and the locking flange 106, wherein the multiple sections may have different thicknesses along the first direction. For example, the locking flange 106 may include a limiting section 108 that is formed by increasing thickness upward along the first direction, and the limiting section 108 may include a stop surface 109 disposed on one side of the limiting section 108 along the rotational direction of the positioning member 104 and the locking flange 106. Specifically, in some embodiments, the limiting section 108 may be formed by an upwardly thickened upper surface of the locking flange 106, and its stop surface 109 may, for example, be disposed on a side of the limiting section 108 away from the release opening 107 along the aforementioned rotational direction. Thus, after the positioning member 104 moves along the locking flange 106 to cross the limiting section 108, the stop surface 109 can be used to secure the positioning member 104 and prevent it from moving back out. Thus, the housing 10 and the housing cover 102 can be locked in the rotation direction, preventing the positioning member 104 from sliding toward the release opening 107 , which would cause the housing cover 102 to become loose or separate from the housing 10 .

[0039] In addition, in some embodiments, the check surface 109 of the limit section 108 and the side surface opposite to the check surface 109 can be set as an inclined transition surface to facilitate the positioning member 104 to smoothly move from the locking flange 106 to the release port 107 when the shell cover 102 is screwed to separate it from the shell 10, so as to facilitate the operation of separating or engaging the shell cover 102 with the shell 10.

[0040] In some embodiments, the housing 10 may further include a stopper sidewall 110, and a locking section 111 may be provided between the stopper sidewall 110 and the stopper surface 109. When the housing cover 102 is locked with the housing 10, the positioning member 104 is located in the locking section 111. The stopper sidewall 110 and the stopper surface 109 are respectively located on either side of the positioning member 104, limiting the horizontal mobility of the positioning member 104 and thereby stabilizing the positioning member 104 in the locking section, thereby preventing the positioning member 104 from sliding along the locking flange toward the release opening 107, which would cause the housing cover 102 to loosen or separate from the housing 10.

[0041] Specifically, in some embodiments, the axial thickness of the locking flange 106 at the locking section 111 can be set to be greater than that of other sections except the limiting section 108. This allows the height of the locking section 111 from the bottom surface of the housing 10 in the first direction to be higher than the lowest surface among the upper surfaces of the locking flange 106. Furthermore, the axial thickness of the locking section 111 can be equal to or slightly greater than the width of the locking groove 105 of the positioning member 104 in the first direction. This limits the positioning member 104 in the first direction and stabilizes the positioning member 104 on the locking section 111, preventing the positioning member 104 from sliding along the locking flange toward the release opening 107, which could cause the housing cover 102 to loosen or separate from the housing 10.

[0042] See also Figure 2 , Figure 2 An exemplary cross-sectional view of an application device with an unscrewing reminder mechanism according to some embodiments of the present disclosure is shown. In some embodiments of the present disclosure, the housing 10 may further include a stopper sidewall 110 for limiting the position of the positioning member 104 in the rotational direction. The stopper sidewall 110 may be configured as a protrusion formed by the locking flange 106 extending in a first direction away from the housing cover 102. A locking section 111 may be disposed between the stopper sidewall 110 and the stop surface 109 along the rotational direction. Thus, when the housing cover 102 is locked relative to the housing 10, the positioning member 104 is located within the locking section 111, abutting the stopper sidewall 110 on one side in the rotational direction and the stop surface 109 of the limiting section 108 on the other side, thereby being bidirectionally constrained and further enhancing its stability in the locked position. Furthermore, the provision of the stopper sidewall 110 prevents the housing cover from being reversely twisted during installation or use, which could result in structural damage.

[0043] In some embodiments, the thickness of the locking flange 106 of the housing 10 along the first direction and / or the protruding height of the ramp section 103 of the housing 10 along the first direction can be set to vary along the relative rotation direction of the housing 10 and the shell cover 102. In this way, different sizes of pressing forces are applied to the positioning member 104 according to the rotation stage of the shell cover 102 relative to the housing 10, so as to further enhance the guidance of the user. For example, by setting the thickness of the locking flange 106 of the housing 10 to be thicker first and thinner later along the relative rotation direction of the housing 10 and the shell cover 102 toward the unscrewing position, the housing 10 and the shell cover 102 can be made to fit more tightly in the first half of the screwing process, and to fit more loosely in the second half. After unscrewing, the shell cover 102 is released along the first direction, and its relaxed state can also remind the user that it has been unscrewed.

[0044] Those skilled in the art will appreciate that, although the above illustrates a housing structure comprising an upper and lower housing, with a ramp provided on the upper housing to abut against the housing cover to provide a reminder of unscrewing, the present disclosure does not limit the actual structure of the housing. For example, a ramp could be provided on the lower housing, with corresponding positioning members or grooves provided on the housing cover. The housing could also include multiple sub-assemblies, or the various housing components could be configured to allow relative movement between them, or only one housing component could be provided.

[0045] Although a plurality of embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art may conceive of many modifications, changes, and alternatives without departing from the ideas and spirit of the present disclosure. It should be understood that in practicing the present disclosure, various alternatives to the embodiments of the present disclosure described herein may be adopted. The appended claims are intended to define the scope of protection of the present disclosure and therefore cover equivalents or alternatives within the scope of these claims.
