The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] To solve relevant technical problems, such as Figure 1 and Figure 3 As shown, the embodiment of the present application provides a cover structure for a transdermal drug delivery therapeutic device, comprising:

[0039] A base 1, wherein the base 1 is provided with a cavity 8 for accommodating a medication tray;

[0040] An upper cover 2, a first end of the upper cover 2 is hinged to an end of the base 1 through a hinge;

[0041] A first elastic connecting member 4 is provided on the upper cover 2;

[0042] The second elastic connector 5 is arranged on the base 1, and the first elastic connector 4 and the second elastic connector 5 are configured to be able to engage with each other under the action of elastic force to lock the upper cover 2 on the base 1, and the upper cover 2 can be unlocked by the action of the first elastic connector 4 or the second elastic connector 5.

[0043] In this embodiment, the base 1 is a part of the main body of the transdermal drug delivery therapeutic device. The upper end of the base 1 is provided with a groove matching the drug delivery disk to form a cavity 8 for accommodating the drug delivery disk. The contour of the cavity 8 is close to the outer contour of the drug delivery disk, and the number of the cavities 8 matches the number of the drug delivery disk. Figure 3 As shown, in one embodiment, four cavities 8 are provided on the base 1, so that four medication trays can be accommodated at the same time. In order to improve the protection effect of the medication tray, in this embodiment, an upper cover 2 is installed on the base 1, and the upper cover 2 is hinged to the base 1, so that the upper cover 2 can be opened and closed in a rotating manner relative to the base 1. In one embodiment of the hinge, the hinge can be a hinge with damping, so that the upper cover 2 can be suspended within a certain angle range by damping after opening.

[0044] On the basis that the upper cover 2 and the base 1 are hinged, in this embodiment, in order to facilitate the closing and opening of the upper cover 2, a first elastic connector 4 is provided on the upper cover 2, and a second elastic connector 5 is provided on the base 1, and the first elastic connector 4 and the second elastic connector 5 serve as a switch button 3. When the upper cover 2 is closed, the first elastic connector 4 and the second elastic connector 5 can bite each other under the action of elastic force, thereby locking the upper cover 2 so that the upper cover 2 cannot be opened. When it is necessary to open the upper cover 2, the first elastic connector 4 or the second elastic connector 5 can be controlled to move according to the corresponding structure so that the two are disengaged, that is, the upper cover 2 is unlocked and can be rotated around the hinge to open. In one embodiment, the first elastic connector 4 can be pushed by pressing, thereby pushing the second elastic connector 5 to move, so that the two are disengaged. Of course, according to the specific structure adopted, the second elastic connector 5 can also be pushed by pressing to push the first elastic connector 4 so that the two fall off and bite. In addition, the method of controlling the movement of the first elastic connector 4 and the second elastic connector 5 is not limited to the pressing method, and can be operated according to the actual structure, and this embodiment does not limit it here.

[0045] On the basis of the above embodiment, in order to further facilitate operation, the first elastic connector 4 is provided on the end of the upper cover 2 away from the hinge, and the second elastic connector 5 is provided on the end of the base 1 away from the hinge.

[0046] This embodiment achieves the purpose of hingedly connecting the upper cover 2 to the base 1 by a hinge, and can unlock the upper cover 2 by pressing the first elastic connector 4 or the second elastic connector 5, so that the upper cover 2 can be rotated to open. After closing the upper cover 2, the first elastic connector 4 and the second elastic connector 5 can automatically lock the upper cover 2 under the action of elastic force, thereby achieving the technical effect of making the opening and closing operations of the upper cover 2 simple and convenient, and facilitating the use and storage of the medication tray, thereby solving the problem of the inconvenience of opening and closing the upper cover 2 of the transdermal drug delivery therapeutic device in the related art.

[0047] In an embodiment in which the first elastic connector 4 and the second elastic connector 5 are linked, the first elastic connector 4 can be operated to move from the first locking position to the first unlocking position and drive the second elastic connector 5 to move from the second locking position to the second unlocking position. In the first locking position and the second locking position, the upper cover 2 is locked on the base 1. In the first unlocking position and the second unlocking position, the upper cover 2 is unlocked.

[0048] And wherein, the second elastic connecting member 5 is configured to be able to move from the second unlocking position to the reset position after the upper cover 2 is opened, and the moving stroke of the second elastic connecting member 5 from the second unlocking position to the reset position is greater than the moving stroke of the second elastic connecting member 5 from the second unlocking position to the second locking position.

[0049] Specifically, it should be noted that when the upper cover 2 is in a locked state, the first elastic connector 4 and the second elastic connector 5 are engaged with each other, and the first elastic connector 4 is in a first locked position, and the second elastic connector 5 is in a second locked position. Moreover, at this time, the second elastic connector 5 is pressed against the first elastic connector 4 under the action of elastic force. When unlocking is required, the first elastic connector 4 can be operated to move from the first locked position to the first unlocked position, and the second elastic connector 5 can be simultaneously pushed to move from the second locked position to the second unlocked position. When the first elastic connector 4 is in the first unlocked position and the second elastic connector 5 is in the second unlocked position, the upper cover 2 is unlocked, so that the upper cover 2 can be opened in a rotational manner.

[0050] In order to facilitate the first elastic connector 4 and the second elastic connector 5 to engage with each other to lock the upper cover 2 hinged to the base 1, in this embodiment, the movement directions of the first elastic connector 4 and the second elastic connector 5 are perpendicular to each other. Figure 1 As shown, the first elastic connection member 4 can move vertically, and the second elastic connection member 5 can move horizontally.

[0051] In an embodiment of the first elastic connector 4, the first elastic connector 4 includes a first clamping member 41 and a first elastic member 40, and the second elastic connector 5 includes a second clamping member 51 and a second elastic member 50;

[0052] The first elastic member 40 is used to drive the first clamping member 41 to move from the first unlocking position to the first locking position, and the second elastic member 50 is used to drive the second clamping member 51 to move from the second unlocking position to the second locking position and the reset position;

[0053] In the first locking position and the second locking position, the first latching member 41 and the second latching member 51 are engaged.

[0054] In this embodiment, the first elastic member 40 is made of an elastic material, one end of which is connected to the flip cover, and the other end is connected to the first clamping member 41. In the process of unlocking the upper cover 2, the first elastic member 40 is in a compressed state. Similarly, the second elastic member 50 is also made of an elastic material, one end of which is connected to the base 1, and the other end is connected to the second clamping member 51. In the process of unlocking the upper cover 2, the second elastic member 50 is in a compressed state, and when the upper cover 2 is locked, the second elastic member 50 is also in a compressed state. In both cases, in the process of unlocking the upper cover 2, the compression degree of the second elastic member 50 is greater than the compression degree of the second elastic member 50 when the upper cover 2 is locked. The first elastic member 40 and the second elastic member 50 can be set as springs or spring plates.

[0055] According to the movement direction of the first elastic connector 4 and the second elastic connector 5, in this embodiment, the first clamping member 41 is configured to be able to move in a vertical straight line, and the second clamping member 51 is configured to be able to move in a horizontal straight line. Accordingly, in order to enable the first clamping member 41 and the second clamping member 51 to move stably and accurately, corresponding slide grooves or slide rails can be provided on the upper cover 2 and the base 1, and the slide grooves or slide rails are used to guide the movement of the two clamping members.

[0056] Since the locking of the upper cover 2 is achieved by the mutual engagement of the first clamping member 41 and the second clamping member 51, and the unlocking of the upper cover 2 is achieved by the action of the first clamping member 41 and the action of the second clamping member 51, Figure 2 As shown, in this embodiment, the first clamping member 41 includes a first abutting surface 410, and the second clamping member 51 includes a second abutting surface 510. The first abutting surface 410 and the second abutting surface 510 are mutually matching inclined surfaces; the first abutting surface 410 can be engaged with the second abutting surface 510 to push the second clamping member 51 to move from the second locking position to the second unlocking position, and the second abutting surface 510 can be pressed against the first abutting surface 410 under the action of the second elastic member 50 to lock the upper cover 2.

[0057] When the first abutting surface 410 and the second abutting surface 510 are engaged with each other in an inclined plane, the first clamping member 41 is pressed downward, and the second clamping member 51 can be pushed in the horizontal direction, so that the first clamping member 41 can be smoothly moved to the first unlocking position. When the upper cover 2 is closed, the second clamping member 51 can apply a force in the horizontal direction to the first clamping member 41, so that the upper cover 2 is pressed tightly in a locked state.

[0058] Since the first abutting surface 410 and the second abutting surface 510 are inclined surfaces, when locked, the horizontal force exerted by the second abutting surface 510 on the first abutting surface will be decomposed into vertical and horizontal directions. In order to enable the upper cover 2 to be locked in the closed state, it is necessary to reduce the force decomposed into the vertical direction. Figure 2 As shown, in this embodiment, the first abutting surface 410 includes a first surface 4101 and a second surface 4102 distributed vertically, and the second abutting surface 510 includes a third surface 5101 and a fourth surface 5102 distributed vertically;

[0059] An obtuse angle is formed between the first surface 4101 and the second surface 4102 , an acute angle is formed between the first surface 4101 and the vertical direction, the third surface 5101 cooperates with the second surface 4102 , and the fourth surface 5102 cooperates with the first surface 4101 .

[0060] Specifically, the first surface 4101 and the third surface 5101, which have a smaller inclination angle relative to the vertical, are in contact, so that the second abutting surface 510 can better abut against the first abutting surface 410 in the horizontal direction when locked. And the second surface 4102 and the fourth surface 5102, which have a larger inclination angle relative to the vertical, are in contact, so that when the upper cover 2 needs to be unlocked, the first abutting surface 410 can better push the second abutting surface 510 to move.

[0061] To facilitate the installation and movement of the first elastic member 40 and the first clamping member 41 on the upper cover 2, in this embodiment, a first guide groove and a first positioning column are provided on the upper cover 2, the first positioning column is located in the first guide groove, the first elastic member 40 is configured as a spring sleeved on the first positioning column, and the first clamping member 41 is slidably disposed in the first guide groove and connected to the first elastic member 40.

[0062] Similarly, to facilitate the installation and movement of the second elastic member 50 and the second clamping member 51 on the base 1, in this embodiment, a second guide groove and a second positioning column are provided on the base 1; the second positioning column is located in the second guide groove, the second elastic member 50 is configured as a spring sleeved on the second positioning column, and the second clamping member 51 is slidably disposed in the second guide groove and connected to the second elastic member 50.

[0063] On the basis of this embodiment, in order to limit the maximum upward movement stroke of the first clamping member 41 in the first guide groove, a corresponding limiting structure can be provided on the first guide groove and the first clamping member 41, and the two limiting structures can be abutted against each other to limit the maximum upward movement stroke of the first clamping member 41. Similarly, for the second clamping member 51, a corresponding limiting structure can be arranged on the second guide groove to limit the second clamping member 51 from leaving the second guide groove.

[0064] To facilitate opening the upper cover 2 after the upper cover 2 is unlocked, Figure 1 and Figure 3 As shown, in this embodiment, an elastic telescopic member 6 is provided between the base 1 and the upper cover 2, and its two ends are connected to the base 1 and the upper cover 2 respectively. When the upper cover 2 is closed onto the base 1, the elastic telescopic member 6 is pressed and is in a compressed state. When the switch button 3 is operated to unlock the upper cover 2, the elastic telescopic member 6 will push the upper cover 2 upward under its own elastic force, so that the upper cover 2 automatically rotates upward to a certain angle and is in an open position. At this time, even if the switch button 3 is released, the upper cover 2 is in a state that can be opened freely. Therefore, in the subsequent opening process of the upper cover 2, it is no longer necessary to keep operating the switch button 3, so that the opening of the upper cover 2 is more convenient.

[0065] This embodiment achieves the purpose that after the upper cover 2 is unlocked by operating the switch button 3, the upper cover 2 will automatically rotate a certain angle to the open position under the elastic force of the elastic telescopic member 6, and the upper cover 2 can be freely opened at this time, thereby achieving the technical effect that only the switch button 3 needs to be operated when the upper cover 2 is unlocked, and the upper cover 2 can automatically open a certain angle, making the opening process of the upper cover 2 more convenient, thereby solving the problem in the related art that the upper cover 2 of the transdermal drug delivery therapeutic device needs to keep the state of the operation button before opening after unlocking, which makes the opening of the upper cover 2 more inconvenient.

[0066] Since the elastic member 6 needs to push the upper cover 2 upwards under the action of its own elastic force so that the upper cover 2 can rotate around the hinge, in order to increase the lever arm, the elastic member 6 in this embodiment is arranged away from the hinge.

[0067] In one arrangement of the elastic telescopic member 6, the elastic telescopic member 6 is disposed on the base 1, and its upper end extends out of the base 1 and abuts against the inner side of the upper cover 2. In another arrangement of the elastic telescopic member 6, the elastic telescopic member 6 is disposed on the inner side of the upper cover 2, and its lower end extends out of the inner side of the upper cover 2 and abuts against the upper end surface of the base 1.

[0068] like Figure 1 As shown, when the elastic telescopic member 6 is selected to be installed on the base 1, in order to facilitate the installation and movement of the elastic telescopic member 6, a mounting groove 7 is opened on the base 1 in this embodiment, the elastic telescopic member 6 is arranged in the mounting groove 7, and the upper end of the elastic telescopic member 6 extends out of the mounting groove 7.

[0069] In this embodiment, the profile of the mounting groove 7 matches the profile of the elastic telescopic member 6, and the elastic telescopic member 6 can slide vertically in the mounting groove 7. In one embodiment of the elastic telescopic member 6, the elastic telescopic member 6 includes a spring pin 61 and a third elastic member 60, both of which are arranged in the mounting groove 7, and the two ends of the third elastic member 60 are respectively against the spring pin 61 and the bottom of the mounting groove 7, and the upper end of the spring pin 61 extends out of the mounting groove 7.

[0070] Specifically, it should be noted that the spring pin 61 can be set as a columnar structure, which has a certain rigidity, so as to better push the upper cover 2 to open. In one embodiment, a connecting groove can be optionally opened in the spring pin 61, and the third elastic member 60 is a spring and is sleeved in the connecting groove, and the lower end of the spring extends out of the connecting groove and abuts against the bottom of the installation groove 7.

[0071] To prevent the spring pin 61 from being separated from the mounting groove 7, Figure 1 As shown, in this embodiment, a first limiting edge 70 is provided at the upper end of the mounting groove 7, and a second limiting edge 610 opposite to the first limiting edge 70 is provided on the elastic pin 61. The first limiting edge 70 and the second limiting edge 610 can cooperate with each other to limit the maximum extension amount of the elastic pin 61.

[0072] Since the spring pin 61 moves along a vertical straight line, and the upper cover 2 rotates around the hinge, friction will be generated between the two when the spring pin 61 pushes the upper cover 2 to open. To reduce friction, in this embodiment, the end of the spring pin 61 close to the upper cover 2 is set to a round head end.

[0073] In one embodiment of the hinge, the hinge is configured as a damping hinge so that the upper cover 2 can hover at any position within a set angle range under the action of damping. Since the hinge itself has damping, an elastic structure such as a torsion spring cannot be installed on the hinge to enable the upper cover 2 to automatically open after being unlocked. Therefore, an additional elastic telescopic member 6 can be selected to push the unlocked upper cover 2 to open to a certain angle.

[0074] According to another aspect of the present application, a transdermal drug delivery therapeutic device is provided, comprising the above-mentioned cover structure.

[0075] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Within the spirit and principle of the present application, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.
