Description

Technical Field

[0001] This utility model relates to ocular medical devices, and in particular to a meibomian gland treatment device. Background Technology

[0002] In the human eye, the tear film covering the cornea consists of three layers: the mucus layer, the aqueous layer, and the lipid layer. The mucus layer, adhering closely to the corneal surface, is mainly composed of mucus rich in viscous proteins and acts as a basal layer. Next is the aqueous layer, which forms the main body of the tear film. Its importance lies in providing necessary lubrication and protection to the eyeball, thus preventing corneal dryness. The outermost layer is the lipid layer, composed of a series of lipid substances called meibomian fat or sebum. Although relatively thin, usually no more than 250 nm, this layer forms a protective covering on the tear film surface, effectively slowing down the evaporation rate of water from the aqueous layer and maintaining the eye's moisture. During blinking, the lipid layer also provides lubrication to the eyelids, further preventing dry eye syndrome. Dry eye syndrome is a well-known eye condition, typically characterized by dryness and discomfort in the eyes. By adjusting and improving the lipid layer, the tear evaporation rate can be effectively reduced and eye lubrication enhanced, thereby alleviating or completely curing the symptoms of dry eye to some extent.

[0003] The meibomian glands play a crucial role in the structure of the eye. These specialized fatty glands, located on the inner side of the upper and lower eyelids, are responsible for secreting lipids that form the outermost layer of the tear film. The surface of the meibomian glands is covered with pores through which lipid secretions are released to the eyelid margins. When mammals blink, these lipid secretions are dispersed, forming the lipid layer of the tear film. Inside the meibomian gland, there are multiple sac-like acini responsible for channeling secretions into the central duct of the gland. Notably, the openings of the meibomian glands are located at the junction of the internal mucosa and the external skin. However, the openings of the meibomian glands are susceptible to problems such as inflammation, leading to blockage. This blockage prevents the normal drainage of fluid from the meibomian glands, thus affecting the integrity of the lipid layer. If the lipid layer is incomplete or insufficient in quantity, it can lead to accelerated evaporation of the aqueous layer, potentially causing various types of dry eye. Furthermore, blockage of the meibomian glands can also cause eye diseases such as meibomianitis (stye) and meibomian cysts (chalazion).

[0004] Dry eye is a common eye condition with diverse causes, but the inability of the meibomian glands to produce an adequate lipid layer is the primary cause of common dry eye symptoms. This condition is called meibomian gland dysfunction, or MGD for short. MGD is mainly caused by blockage of the meibomian glands. Blockage of the meibomian glands further restricts the flow of sebum, which promotes cell growth around the gland pores, thus worsening the blockage. In addition, the coagulation of sebum at the blockage site also exacerbates the problem. Various methods have been developed to treat dry eye. These methods include eye drops designed to mimic and replace the natural aqueous tear film, and medications designed to stimulate tear-producing cells. The goal of these medications is to replicate the naturally generated healthy tear film as closely as possible. However, these are only treatments for the surface symptoms and do not address the root cause of the problem: meibomian gland blockage and dysfunction.

[0005] Currently, the main clinical treatments for meibomian gland dysfunction (MGD) include warm compresses and pressure massage. Both methods aim to soften and remove blockages located in the meibomian gland ducts. Traditional pressure massage is usually performed after warm compresses, with medical staff using a glass rod, cotton swab, or medical forceps to squeeze the eyelid. However, this procedure is often painful and may cause fear in patients, creating a psychological burden during treatment. Furthermore, the lack of heat preservation during pressure massage can lead to a drop in temperature in the treated area, causing the blockage to re-coagulate. Therefore, warm compresses need to be repeated periodically, making the procedure cumbersome and difficult to control precisely. These issues limit the effectiveness and patient acceptance of traditional treatments.

[0006] Although existing technologies offer various medical devices for meibomian gland massage to address patient acceptance and the issue of meibomian gland blockage coagulation during the procedure, these devices all require an intraocular pad structure. This pad is placed between the eyelid and cornea, and external force is used to squeeze the meibomian glands in the eyelid, thereby allowing the meibomian fat to drain. Due to the working principle of the intraocular pad, topical anesthetic medication needs to be applied during the treatment. This imposes strict restrictions on the qualifications of institutions that can use such devices. Some community optometry centers cannot use these devices, and patients cannot perform self-treatment at home.

[0007] EP3773380A1 discloses a system for treating dry eye syndrome, which utilizes radiant energy through an eye patch and headband. However, the eye patch treatment system of EP3773380A1, with its relatively loose structure, suffers from poor stability and treatment precision. Furthermore, relying solely on radiant energy, this system is insufficient to adequately soften blockages in the meibomian glands, resulting in inadequate effectiveness in promoting meibomian gland drainage and impacting the treatment efficacy for meibomian gland-related diseases.

[0008] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

By incorporating two sets of slide rails within the lower housing, the assembly ends of the upper and lower meibomian gland heating pads can be slidably coupled to the slide rails, achieving both limiting and sliding functions. This allows for flexible adjustment of the heating pad position according to the patient's eyelid shape and treatment needs, ensuring a close fit between the heating pad and the eyelid and improving treatment efficacy. The upper and lower meibomian gland heating pads are used to heat the upper and lower eyelids respectively, softening the meibomian fat in the upper and lower meibomian glands and promoting its discharge.

[0042] In a preferred embodiment, the lower eyelid heating pad is a lower eyelid heating electrode 120, used to heat the lower eyelid, soften the meibomian gland in the lower eyelid, and provide electrical stimulation; wherein, the lower eyelid heating electrode 120 includes a heating area and an electrical stimulation area, the electrical stimulation area being used to apply electrical stimulation to the orbicularis oculi muscle nerve to induce blinking; the control circuit is also used to control the intensity and frequency of the electrical stimulation of the lower eyelid heating electrode 120.

[0043] In a preferred embodiment, the slide rail includes two parallel slide bars with a gap. Keyways 1303 and 1304 are provided on the sides of the slide bars. The assembly ends of the upper eyelid heating plate 110 and the lower eyelid heating electrode plate 120 are disposed between the two slide bars and key bodies 1101, 1102, 1201, and 1202 are provided on both sides. By cooperating with the key bodies and the keyways 1303 and 1304 on the two slide bars, the limiting and sliding on the slide rails 1301 and 1302 are realized.

[0044] In some embodiments, the control circuit is disposed on a PCB board 150, which is fixed inside the lower housing 130.

The device is equipped with a control circuit that can precisely adjust the heating temperature and the intensity and frequency of electrical stimulation to meet the treatment needs of different patients.

[0047] The following further describes specific embodiments of this utility model.

[0048] See Figures 1A to 5 A meibomian gland treatment device includes an upper tarsal heating plate 110, a lower tarsal heating electrode 120, a lower housing 130, and an upper housing 140, a chip 150, and a battery 160. The lower housing 130 is provided with a slide rail 1301 coupled to the upper tarsal heating plate 110 and the lower tarsal heating electrode 120. The slide rail 1302 has a keyway 1303. The keyway 1304 cooperates with two key bodies 1101 and 1102 of the upper tarsal heating plate and two key bodies 1201 and 1202 of the lower tarsal heating electrode to form a limiting position. The battery 160 is directly embedded in a battery slot 1305. The chip 150 is connected to the lower housing 130 via four stacked screw holes 1306. The lower housing 130 has four symmetrical screw holes 1307 connected to the upper housing 140 via four symmetrical screw holes 1401.

[0049] like Figure 1A and Figure 1B As shown, the structure includes an upper eyelid heating pad 110, a lower eyelid heating electrode pad 120, a lower housing 130, an upper housing 140, a chip 150, and a battery 160. The structure is a bilaterally symmetrical structure.

[0050] like Figure 2 As shown, the lower eyelid heating electrode 1203 is the heating area, and the 1204 area is the electrical stimulation area. Hydrogel will be adhered to the 1204 area to apply electrical stimulation, and there are bonds 1201 and 1202 at the rear end.

[0051] like Figure 3 The upper tarsal heating pad shown only has the function of heating the upper tarsal plate, and has keys 1101 and 1102 at the rear end.

[0052] like Figure 4 The lower housing 130 shown includes slide rails 1301 and 1302, with keyways 1303 and 1304 on the sides of the slide rails. It also has a battery slot 1305 and four symmetrical screw holes 1306, and four symmetrical screw holes 1307 on the edge of the lower housing 130. A battery charging port 1308 is located on the side.

[0053] like Figure 5The diagram illustrates the assembly structure of an upper tarsal heating pad 110, a lower tarsal heating electrode 120, a lower housing 130, a chip 150, and a battery 160. The keys 1201 and 1202 of the lower tarsal heating electrode 120 form a keyed connection with the keyway 1304 of the lower housing 130, and together with the slide rail 1302, they form a limiting position, allowing the lower tarsal electrode 120 to slide one-dimensionally within a certain range on the slide rail. Similarly, the keys 1101 and 1102 of the upper tarsal heating pad 110 form a keyed connection with the keyway 1303 of the lower housing 130, and together with the slide rail 1301, they form a limiting position, allowing the upper tarsal electrode 110 to slide one-dimensionally within a certain range on the slide rail. The battery 160 is fitted into the battery slot 1305 of the lower housing and directly embedded in the assembly. The charging port 1308 is fitted into the battery charging interface, and the two are concentrically aligned. The chip 150 and the four symmetrical screw holes 1306 are connected by bolts.

[0054] See Figure 2 Both the upper tarsal heating pad 110 and the lower tarsal heating electrode 120 have heating functions. The controller sends a heating signal to the heater, which heats up the upper tarsal heating pad 110 and the lower tarsal heating electrode 120. The upper tarsal heating pad 110 and the lower tarsal heating electrode 120 can transfer heat to the patient's eyelids, raising the temperature of the patient's eyelids to a maximum of 42 degrees Celsius. At this temperature, the blockage in the meibomian glands softens. After softening by heating, the area of ​​the lower tarsal heating electrode 1204 becomes an electrical stimulation area, which will electrically stimulate the nerve in the lower part of the lower tarsal plate, thereby stimulating the orbicularis oculi muscle to contract strongly. The contracted orbicularis oculi muscle, together with the eyeball, will exert pressure on the meibomian glands, causing the meibomian fat in the meibomian glands to be squeezed out.

[0055] Using this meibomian gland therapy device, rhythmic contraction and relaxation of the orbicularis oculi muscle are induced by electrical stimulation of the orbicularis oculi muscle nerve, thereby causing rhythmic blinking of the eyelids. During treatment, a specific waveform current is generated by an electrical stimulation generator. This current is evenly conducted to the orbicularis oculi muscle nerve through a conductive sheet and disposable treatment consumables, triggering a specific rhythmic blinking movement. In this state, the outward pressure of the eyeball during blinking simulates a meibomian gland massage action, squeezing out the melted meibomian gland fat, thus unblocking the meibomian gland ducts and achieving a therapeutic effect on meibomian gland disorders. Furthermore, the meibomian gland therapy device is equipped with a heating mechanism. Before applying electrical stimulation, the upper and lower eyelids are fully heated to 42.5°C through contact, melting the solidified meibomian gland fat in the patient's meibomian glands, resulting in even better therapeutic effects.

[0056] This utility model, in a preferred embodiment, is a meibomian gland therapy device based on electromuscular stimulation. It may include a main body, a heating mechanism, an electrical stimulation generator, conductive pads, disposable treatment consumables, a power supply, and a PCB board. In use, the product is worn around the patient's head, with the upper and lower tarsal heating pads respectively attached to the corresponding eyelid areas. The device is activated via buttons on the casing. These buttons allow adjustment of the heating temperature and the intensity and frequency of the stimulation current. Heating with the heating pads promotes the melting of meibomian fat within the tarsal plate, and electrical stimulation achieves a rapid blinking effect. The patient squeezes out the meibomian fat through blinking. This meibomian gland therapy device's electrical stimulation scheme has advantages such as simple and reliable structure, no need for anesthesia, and easy operation, allowing patients to perform treatment at home.
