Description

Technical Field

[0001] The utility model relates to an eye medical device, in particular to a meibomian gland therapeutic device. Background Art

[0002] In the human eye, the tear film covering the cornea is composed of three layered structures. These three layers are, from the inside to the outside: mucus layer, aqueous layer and lipid layer. The mucus layer is close to the surface of the cornea and is mainly composed of mucus rich in sticky proteins, which acts as a basal layer. The second is the aqueous layer, which constitutes the main body of the tear film. Its importance lies in providing the necessary lubrication and protection for the eyeball, thereby preventing the cornea from drying out. The outermost is the lipid layer, which is composed of a series of lipid substances called meibum or sebum. Although this layer is relatively thin, usually not exceeding 250nm, it forms a protective covering layer on the surface of the tear film, effectively slowing down the evaporation rate of the aqueous layer and maintaining the moist state of the eyes. During the blinking action, the lipid layer can also provide lubrication for the eyelids, thereby preventing the occurrence of dry eye syndrome. Dry eye syndrome is a well-known eye disease, which is usually manifested as dry and uncomfortable eyes. By adjusting and improving the lipid layer, the tear evaporation rate can be effectively reduced and eye lubrication can be enhanced, thereby alleviating or completely curing the symptoms of dry eye to a certain extent.

[0003] Meibomian glands play an important role in the structure of the eye. These specialized fat glands are located on the inner side of the upper and lower eyelids and are responsible for secreting lipids that form the outermost layer of the tear film. The surface of the meibomian glands is covered with holes, through which lipid secretions are discharged to the edge of the eyelids. When mammals blink, these lipid secretions are dispersed, forming the lipid layer of the tear film. Inside the meibomian glands, there are multiple cystic alveoli, which are responsible for flowing secretions into the central duct of the gland. It is worth noting that the opening of the meibomian gland is located at the junction of the inner mucosa and the outer skin. However, the opening of the meibomian gland is easily affected by problems such as inflammation, leading to blockage. This blockage prevents the normal discharge of the meibomian gland fluid, which in turn affects the integrity of the lipid layer. If the lipid layer is not sound or the amount of lipids is insufficient, the evaporation of the aqueous layer will be accelerated, which may eventually cause various dry eye diseases. In addition, the blockage of the meibomian glands may also cause eye diseases such as meibomitis (sty) and meibomian gland cysts (granulomas).

[0004] Dry eye is a common eye disease with a variety of causes, but the inability of the meibomian glands to adequately produce a lipid layer is the main cause of common dry eye symptoms. This condition is called "meibomian gland dysfunction," or MGD for short. MGD is mainly caused by the blockage of the meibomian glands. The blockage of the meibomian glands further restricts the flow of sebum, which promotes cell growth around the gland openings, which worsens the blockage of the meibomian glands. In addition, the solidification of sebum at the blockage site can also worsen the blockage of the meibomian glands. Various treatments have been developed to treat dry eye. These include drops designed to simulate and replace the natural aqueous tear film, and drugs designed to stimulate tear-producing cells. The goal of these drugs is to replicate the healthy tear film that is naturally produced as closely as possible. However, these are only symptomatic treatments and do not address the root cause of the problem, which is the blockage and dysfunction of the meibomian glands.

[0005] Currently, the main methods for clinical treatment of meibomian gland dysfunction (MGD) include meibomian gland hot compress and squeeze massage. The purpose of these two methods is to soften and remove the blockage in the meibomian gland channel. The traditional meibomian gland massage method is usually performed after hot compress, and medical staff will use glass rods, cotton swabs or medical tweezers to squeeze the eyelids. However, this treatment process is often accompanied by pain, which may trigger the patient's fear, thereby creating a psychological burden in the process of treating the disease. In addition, during the squeezing process, the temperature of the treatment area may drop due to the lack of heating and insulation of the eyelids, causing the blockage to solidify again. Therefore, it is necessary to re-apply hot compresses at regular intervals, which not only makes the operation process cumbersome, but also the force control is not precise. These problems limit the effectiveness of traditional treatment methods and patient acceptance.

[0006] Although the prior art has provided a variety of treatment methods for dry eye, these methods mainly treat symptoms rather than directly address the root cause. In fact, the main problem for many dry eye patients is the obstruction or occlusion in the meibomian glands. Therefore, an effective treatment method for the meibomian glands is urgently needed. However, the above-mentioned clinical treatment methods rely heavily on the operator's skills and experience, and the operation process is complicated and cumbersome, which puts a heavy burden on patients. Therefore, it is necessary to develop a treatment method that is simpler, less burdensome to patients and can directly solve the root problem.

[0007] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, connection can be used for fixing as well as for coupling or communication.

[0042] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0044] See Figures 1 to Figure 8The embodiment of the utility model provides a meibomian gland therapeutic instrument, including a body shell 220, a roller 110, an intermediate gear 120, a connecting rod, a connecting frame 170, a massage head 180 and a bottom pad 200, a part of the roller 110 is exposed from the notch of the body shell 220, a small gear that rotates synchronously with the roller 110 is arranged on the roller shaft 113 of the roller 110, the small gear is meshed with the intermediate gear 120, the intermediate gear 120 and the roller shaft 113 are mounted on the connecting frame 170, one end of the connecting rod is connected to the eccentric part of the intermediate gear 120, the other end of the connecting rod extends out of the rear end of the connecting frame 170 and is connected to the massage head 180, the roller 110 is equipped with a torsion spring, which is wound around the roller shaft 113. The two ends of the torsion spring are respectively coupled to the connecting frame 170 and the roller 110. The bottom pad 200 is inserted between the eyelid and the cornea during treatment. When the roller 110 is pressed down, the roller 110 overcomes the elastic force of the torsion spring and moves forward to make the massage head 180 approach the bottom pad 200. When the roller 110 is released, the torsion spring recovers to make the massage head 180 retreat. When the roller 110 is rolled, the rotation of the roller 110 drives the connecting rod to swing through the pinion and the intermediate gear 120, thereby driving the massage head 180 to press and move along the extension direction of the bottom pad 200.

[0045] The meibomian gland treatment device's pressing mechanism can be used to treat meibomian gland dysfunction by pressing. During the treatment process, by pressing down and rolling the roller, when the massage head is close to the eyelid, the pressing mechanism converts the rotation of the roller into a pressing movement of the massage head along the extension direction of the eyelid (at this time, the movement of the massage head is similar to a linear movement along the eyelid), and the blockage in the meibomian gland is squeezed out, thereby unblocking the meibomian gland channel and achieving the treatment effect of meibomian gland dysfunction.

[0046] The design of the roller equipped with a torsion spring in the utility model provides a mechanism that can achieve fine control and buffering functions. The torsion spring is wound around the roller shaft, and its two ends are respectively coupled to the connecting frame and the roller. This configuration enables the roller to overcome the elastic force of the torsion spring and move forward when pressed down, thereby pushing the massage head closer to the bottom pad to achieve precise massage of the eyelids. When the roller is released, the restoring force of the torsion spring can make the massage head retreat, providing the necessary return stroke for the treatment process. This design not only ensures the continuity and consistency of the massage action, but also avoids excessive pressure or potential damage to the patient's eyelids through the buffering effect of the torsion spring, thereby improving the safety and comfort of the treatment.

[0047] See also Figure 1B , Fig. 6A and Figure 7In some embodiments, the torsion spring 130 is wound around the roller shaft 113, one end of the torsion spring 130 hooks the torsion spring slot 173 of the connecting frame 170, and the other end extends into the groove of the roller 110. In the initial position, the torsion spring is pre-tightened or not pre-tightened. When the roller 110 moves forward, the torsion spring 130 rotates from one end in the groove of the roller 110 to the other end, and the torsion spring is compressed. The torsion spring can reset the pressing mechanism and provide a buffering effect to prevent the operator from injuring the patient's eyelids by applying too much force.

[0048] The specific embodiments of the present utility model are further described below.

[0049] See Figures 1 to Figure 8In some embodiments, the meibomian gland therapeutic device includes a body shell, a pressing mechanism and a bottom pad, the pressing mechanism includes a roller 110, an intermediate gear 120, a torsion spring 130, a front connecting rod 140, a pressure sensor 150, a rear connecting rod 160, a connecting frame 170 and a massage head 180, and the roller shaft 113 of the roller 110 is provided with small gears 1101 and 1102 that rotate synchronously with the roller 110, and the small gears 1101 and 1102 are meshed with the intermediate gear 120, and the front connecting rod 1 The first end of the front connecting rod 140 is connected to the eccentric shaft 1211 and 1221 of the intermediate gear 120, the second end of the front connecting rod 140 is fixed to the rear end of the pressure sensor 150, the first end of the rear connecting rod 160 is fixed to the front end of the pressure sensor 150, the intermediate gear shaft hole and the roller shaft 113 hole are provided on the connecting frame 170, the intermediate gear shaft and the roller shaft 113 are respectively installed in the intermediate gear shaft hole and the roller shaft 113 hole, the rear end of the connecting frame 170 is provided with a groove and a clamping column, and the rear connecting rod 160 is installed in the intermediate gear shaft hole and the roller shaft 113 hole. The second end of the rear connecting rod 160 extends out of the rear end of the connecting frame 170 between the groove and the clamping column, and the massage head 180 is connected to the second end of the rear connecting rod 160. The roller 110 is provided with parallel grooves inside, and the lower side of the connecting frame 170 is provided with a torsion spring groove 173. The torsion spring 130 is provided on the roller shaft 113 and coupled between the groove and the torsion spring groove 173. When the roller 110 is pressed down, the roller 110 overcomes the elastic force of the torsion spring 130 and drives the pressing mechanism to move forward so that the massage head 180 moves along the roller shaft 113. The roller 110 moves straight away from the connecting frame 170. When the roller 110 is released, the torsion spring 130 is restored so that the roller 110 drives the pressing mechanism and the massage head 180 to retreat. When the roller 110 is rolled, the rotation of the roller 110 drives the rear connecting rod 160 to swing between the groove and the column through the pinions 1101 and 1102, the intermediate gear 120, the front connecting rod 140 and the pressure sensor 150, thereby driving the massage head 180 to make a curved motion away from the connecting frame 170 in both horizontal and vertical directions.

[0050] The front and rear connecting rods are provided with symmetrical groove structures, and the pressure sensor is placed between the two symmetrical grooves. The pressure measurement direction is parallel to the movement direction of the two connecting rods. During the treatment process, when the roller 110 is pressed down, the roller 110 overcomes the elastic force of the torsion spring 130 and drives the pressing mechanism to move forward so that the front connecting rod 140, the pressure sensor 150, the rear connecting rod 160, and the massage head 180 move in a direction away from the connecting frame 170 as a whole. When the massage head 180 stops when it encounters the outer surface of the eyelid, it will limit the movement of the rear connecting rod 160 and the pressure sensor 150. At this time, the front connecting rod continues to move, pressing the pressure sensor to generate a reading.

[0051] The bottom pad is detachably mounted on the housing. During treatment, the bottom pad is inserted between the eyelid and the cornea. When the massage head is close to the bottom pad, the pressing device converts the rotation of the roller into a pressing movement of the massage head along the extension direction of the bottom pad (at this time, the movement of the massage head is similar to the linear movement along the bottom pad), exerting a pressing effect on the patient's eyelid sandwiched between the massage head and the bottom pad, and squeezing out the blockage in the meibomian gland. After the bottom pad is loaded, it will not fall off due to its own movement. The bottom pad is a consumable and can be quickly replaced with a new one after use.

[0052] Referring to FIG. 6 , in a preferred embodiment, a heater 121 is provided inside the massage head. While applying pressure to the eyelids, the heater heats the patient's eyelids. The blockage in the patient's meibomian glands is softened by the heat and squeezed out by pressure, achieving a better therapeutic effect.

[0053] like Figure 1A and Figure 1B As shown, the pressing mechanism includes a roller 110, an intermediate gear 120, a torsion spring 130, a front connecting rod 140, a pressure sensor 150, a rear connecting rod 160, a connecting frame 170 and a massage head 180. The pressing mechanism is a bilaterally symmetrical mechanism.

[0054] like Figure 2 As shown, the massage head 180 is connected to one end of the rear connecting rod 160 , and a groove 161 is formed on the other end of the rear connecting rod 160 .

[0055] FIG. 3A to FIG. 3B The intermediate gear 120 is shown. The intermediate gear may have more than one gear. In this example, there are two gears 121 and 122, which are arranged symmetrically. An eccentric shaft 1211 and 1221 is provided on the inner circumference of each gear 121 and 122, and a support 1212 and 1222 are provided at the root of the eccentric shaft 1211 and 1221. Figure 4A , FIG. 6A to FIG. 6C As shown, the connecting frame is provided with fan-shaped holes 1713, 1723 near the intermediate gear shaft, and the eccentric shafts 1211, 1221 are restricted to rotate within the fan-shaped holes 1713, 1723 of the connecting frame 170, thereby limiting the rotation angle of the intermediate gear.

[0056] FIG. 4A to FIG. 4CThe structure of the assembly of the intermediate gear 120, the front connecting rod 140, the pressure sensor 150, the rear connecting rod 160, the connecting frame 170, and the massage head 180 is shown. The diameters of the holes 141 and 142 on the front connecting rod 140 are matched with the diameters of the eccentric shafts 1211 and 1221 on the intermediate gear 120, the hole 141 is matched with the shaft 1211, and the hole 142 is matched with the shaft 1221. The connecting frame 170 has shafts 1712 matched with the number of intermediate gears, and the two shafts 1712 are arranged symmetrically as shown in the figure. The diameter of the shaft 1712 is matched with the diameters of the holes 121 and 122 on the intermediate gear 120, and the shaft 1712 is matched with the holes 121 and 122. The inner surface of the intermediate gear 140 faces the connecting frame 170. The connecting frame 170 is provided with a groove and a clamping column for the rear connecting rod 160 to pass through. The size of 189 at the cross section formed by the groove and the clamping column is equal to the size of the cross section of the rear connecting rod 160. The contact mode between the rear connecting rod 160 and the connecting frame 170 is line contact, and the rear connecting rod can slide and rotate between the groove and the clamping column.

[0057] like FIG. 5A to FIG. 5B As shown, two intermediate gears 121 and 122 are symmetrically arranged on both sides of the roller 110.

[0058] The meshing pinions 1101 and 1102 are coaxial with the roller 110 and have a common shaft hole 111. The pinions 1101 and 1102 are respectively provided with eccentric bosses 1121 and 1122 for limiting the rotation angle. The pinions 1101 and 1102 on the roller 110 are gear-driven with the intermediate gears 121 and 122.

[0059] like Figures 6A to 6C As shown, the holes 1711 and 1721 of the connecting frame 170 are respectively matched with the shafts 1121 and 1122 on the roller 110, and the gears 1101 and 1102 on the roller 110 are gear-driven with the intermediate gears 121 and 122.

[0060] The massage head 180 is also a heat source, and a heater 181 and a temperature sensor 182 are embedded in the massage head. The heater is controlled by a controller. The controller sends a heating signal to the heater, and the heater heats the massage head to increase the temperature. The massage head can transfer heat to the patient's eyelids, so that the temperature of the patient's eyelids increases to a maximum of 42 degrees Celsius, and the blockage in the meibomian gland softens at such a temperature. During the treatment process, the massage head can continuously transfer heat to the eyelids, so that the eyelids maintain temperature during the treatment process. During the treatment process, the massage head continuously transfers heat to the eyelids, while pressing the softened blockage in the meibomian glands to discharge it from the eyelids.

[0061] When the roller is pressed down during use, the relative positions of the roller, the middle gear, the front connecting rod, the pressure sensor, the rear connecting rod and the massage head remain unchanged, and they all move closer to the eyelid as a whole. The pressing mechanism can be manually operated. Pressing the roller moves the massage head closer to the eyelid. By rolling the roller, the massage head can move along the vertical direction of the meibomian gland, and the trajectory of the massage head movement is approximately a straight line. After unloading the force acting on the roller, the pressing mechanism is immediately reset, and the patient's eyelid is no longer under pressure.

[0062] See also Figure 7 and Figure 8 The bottom pad 200 is detachably mounted on the protrusion 2201 on the body shell 220 through buckles 201 and 202. During treatment, the bottom pad is inserted between the eyelid and the cornea. When the massage head is close to the bottom pad, the pressing device converts the rotation of the roller into a pressing movement of the massage head along the extension direction of the bottom pad (at this time, the movement of the massage head is similar to the linear movement along the bottom pad), and applies a pressing effect to the patient's eyelid sandwiched between the massage head and the bottom pad, so that the blockage in the meibomian gland is squeezed out. After the bottom pad is loaded, it will not fall off due to its own movement. The bottom pad is a consumable and can be quickly replaced with a new one after use. A radio frequency chip 210 is provided at the bottom of the bottom pad 200. After the bottom pad buckle and the body shell protrusion are installed, the radio frequency chip 210 will contact the receiving end 2202 of the body shell to enable the device function. If the radio frequency chip is not activated, the device function cannot be enabled normally. And the RF chip can only be identified once, preventing the bottom pad from being recycled.
