[0049] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0050] In the related art, the two clamping arms of the existing massage devices mostly require the hands to continuously exert force on the clamping arms to ensure that the massage component fits the eyelids. Long-term operation can easily cause excessive force on the hands to cause shaking, and it is inconvenient to replace the massage component.

[0051] Figure 1-Figure 5 A structural diagram of a meibomian gland massaging device 100 according to an embodiment of the present application is shown.

[0052] like Figure 1-Figure 5 As shown, the massage device 100 may include:

[0053] A first clamp arm 101 and a second clamp arm 102, wherein the first clamp arm 101 and the second clamp arm 102 are connected via a connecting shaft, and when the meibomian gland is massaged, one end of the second clamp arm 102 is located inside the eyelid;

[0054] A rolling brush 110, which is movably mounted on the first clamping arm 101, and is used for massaging the upper eyelid;

[0055] The reset member 108 is mounted on the first clamping arm 101 , and one end of the reset member 108 is connected to the roller brush 110 so that the roller brush 110 can perform a reset movement relative to the first clamping arm 101 .

[0056] In this embodiment, an anesthetic is applied to one end of the second clamp arm 102 away from the first clamp arm 101 in advance, and after applying the anesthetic, the second clamp arm 102 is placed inside the upper eyelid, and the rolling brush 110 is pulled by hand to massage the meibomian glands on the upper eyelid. When the hand pulls the rolling brush 110 to move, the resetting member 108 contracts accordingly. After the rolling brush 110 is released, the resetting member 108 relaxes to reset the rolling brush 110, and the meibomian glands in the upper eyelid are massaged;

[0057] By setting the roller brush 110, the meibomian glands in the upper eyelid are massaged. During the massage process, one end of the second clamping arm 102 is located inside the upper eyelid, providing a fulcrum for the massage of the roller brush 110, which is convenient for the massage of the roller brush 110. At the same time, by adding the reset member 108, when the roller brush 110 moves, the roller brush 110 can be reset in time, which is more labor-saving than the traditional massage device 100 that needs to manually control the roller brush 110, and ensures that the roller brush 110 is uniformly applied during the massage process, thereby ensuring the comfort during the massage.

[0058] It should be noted that the reset member 108 may be a spring 134, a rubber sleeve or other parts having contraction and reset properties;

[0059] The first clamp arm 101 and the second clamp arm 102 are rotatably connected via a connecting shaft, and the connecting ends of the first clamp arm 101 and the second clamp arm 102 extend backward to form a Figure 2 As shown, the first clamp arm 101 and the second clamp arm 102 form an X shape, which is similar to the usage of scissors, and the first clamp arm 101 and the second clamp arm 102 may not extend backward, but form a V shape for use, which is similar to the usage of existing tweezers.

[0060] like Figure 1-Figure 5 As shown, in one embodiment,

[0061] The roller brush 110 has a movable rod 111, and the first clamping arm 101 has a first cavity 103 with an opening on one side. The first clamping arm 101 is connected to a fixed rod 104, and the fixed rod 104 is located in the first cavity 103. The first clamping arm 101 is detachably connected to an insert block 105, and the insert block 105 closes the opening of the first cavity 103. The movable rod 111 passes through the insert block 105 and is sleeved on the fixed rod 104. The reset member 108 is sleeved on the fixed rod 104, and one end of the reset member 108 is connected to the movable rod 111, and the other end is connected to the first clamping arm 101.

[0062] In this embodiment, when the roller brush 110 is installed, the plug block 105 is pulled out from the first clamp arm 101, and after the plug block 105 is sleeved on the roller brush 110, the roller brush 110 is sleeved on the fixing rod 104. After the sleeve connection is completed, the plug block 105 is reinserted into the first clamp arm 101 to complete the installation of the roller brush 110, so that the roller brush 110 can be easily disassembled;

[0063] When the movable rod 111 is installed, the reset member 108 is preferably sleeved on the fixed rod 104, and then the plug block 105 is sleeved on the movable rod 111. After the movable rod 111 is sleeved on the fixed rod 104, the plug block 105 is plugged into the first clamping arm 101, so that one end of the movable rod 111 is located in the cavity. When the movable rod 111 moves, the spring contracts or relaxes to ensure that the movable rod 111 can be reset in time after the movement. The movable rod 111 drives the roller brush 112 to roll on the surface of the eyelid to massage the meibomian glands.

[0064] It should be noted that the insert block 105 is inserted into the first clamp arm 101 in the form of an insert rod.

[0065] like Figure 1-Figure 5 As shown, in one embodiment,

[0066] The first clamp arm 101 is provided with a first slide groove 106 and a second slide groove 107. The first slide groove 106 is located on the outer side of the first clamp arm 101, and the second slide groove 107 is located on the side of the first clamp arm 101. The first slide groove 106 and the second slide groove 107 are both communicated with the first cavity 103. The first slide groove 106 and the second slide groove 107 both have openings, and the insert block 105 closes the openings of the first slide groove 106 and the second slide groove 107.

[0067] The movable rod 111 is connected to a first slider 113 and a second slider 112 . The first slider 113 slides in the first slide groove 106 , and the second slider 112 slides in the second slide groove 107 . A pull ring is connected to the first slider 113 . The movable rod 111 is controlled to move by holding the pull ring or the second slider 112 .

[0068] In this embodiment, by setting the first slider 113 and the second slider 112 on the movable rod 111, it is convenient to control the movable rod 111 to slide along the fixed rod 104 with one hand, and cooperate with the contraction and relaxation of the reset member 108 to make the roller brush 112 perform a reset movement on the eyelid to massage the meibomian glands. The openings of the first slide groove 106 and the second slide groove 107 are closed by the plug block 105, and the first slider 113 and the second slider 112 slide in the first slide groove 106 and the second slide groove 107 respectively. When the plug block 105 is plugged into the first clamping arm 101, under the action of the first slider 113 and the second slider 112, it is ensured that the end of the movable rod 111 and the fixed rod 104 that is sleeved is always located in the cavity, thereby ensuring the normal use of the roller brush 112. By setting a pull ring on the first slider 113, the movement of the first slider 113 during one-handed operation is facilitated.

[0069] like Figure 1-Figure 5 As shown, in one embodiment,

[0070] The second slide groove 107 and the fixed rod 104 are both arc-shaped, and the shape of the movable rod 111 is adapted to the fixed rod 104, so that the movement path of the roller brush 110 is arc-shaped.

[0071] In this embodiment, by setting the second slide groove 107 and the fixing rod 104 to an arc shape, the movement path of the roller brush 112 is an arc movement, which fits the shape of the eyelid and prevents impurities in the meibomian gland from being pushed back into the eyelid when the roller brush 112 is reset.

[0072] In one embodiment, the massage device 100 further includes:

[0073] The clamping block 120 is detachably mounted on one end of the second clamping arm 102 that fits the eyelid. When the meibomian gland is massaged, the clamping block 120 fits the inside of the upper eyelid, and supports the roller brush 110 when the roller brush 110 is massaging the eyelid.

[0074] The angle adjustment component 130 is installed between the first clamping arm 101 and the second clamping arm 102 to adjust the opening and closing angle of the first clamping arm 101 and the second clamping arm 102 so that the roller brush 110 and the clamping block 120 fit the eyelid.

[0075] In this embodiment, the sterilized roller brush 110 and the clamping block 120 are respectively installed on the first clamping arm 101 and the second clamping arm 102. After the eyelid is treated with anesthetic, the clamping block 120 is attached to the inside of the eyelid. The angle between the first clamping arm 101 and the second clamping arm 102 is adjusted by the angle adjustment component 130 so that the angle between the first clamping arm 101 and the second clamping arm 102 matches the eyelid angle. The meibomian glands on the eyelids are massaged by the roller brush 110 to squeeze out foreign matter in the meibomian glands. After use, the roller brush 110 and the clamping block 120 are removed for replacement and sterilization.

[0076] By detachably mounting the roller brush 110 and the clamping block 120 on the first clamp arm 101 and the second clamp arm 102, it is convenient to thoroughly disinfect the massage device 100 after use, and it is also convenient to replace other types of roller brushes 110. The opening and closing angle between the first clamp arm 101 and the second clamp arm 102 is limited by the angle adjustment component 130, avoiding the need to manually apply force to control the angle between the first clamp arm 101 and the second clamp arm 102 while massaging the eyelids, thereby affecting the operation of the roller brush 110.

[0077] In one embodiment,

[0078] The clamping block 120 has an absorption layer on which anesthetic is applied.

[0079] In this embodiment, when the second clamping arm 102 is placed inside the upper eyelid, anesthetic is applied to the absorption layer in advance to avoid eyelid pain caused by the clamping block 120 being placed inside the upper eyelid.
