Description

Technical Field

[0001] The invention 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 symptoms. In addition, the blockage of the meibomian glands may also cause eye diseases such as meibomitis (sty) and meibomian 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 patients' fear and thus create 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 makes the force control imprecise. These problems limit the effectiveness of traditional treatment methods and patient acceptance.

[0006] Although the prior art has provided a variety of medical devices for meibomian gland massage to solve the problems of patient acceptance and blockage solidification during meibomian gland massage, these devices all require the use of an intraocular gasket structure, which is placed between the eyelid and the cornea, and uses external force to squeeze the meibomian glands in the eyelid to discharge meibum. Due to the working principle of the intraocular gasket, topical anesthetics need to be dripped during the treatment process, which strictly restricts the qualifications of institutions that can use such devices. Some community optometry centers cannot use such devices, and patients cannot perform treatment at home independently.

[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.

[0031] In a preferred embodiment, the upper shell 140 and the lower shell 130 are included to form the main structure of the therapeutic device; wherein, two sets of slide rails 1301 and 1302 are provided inside the lower shell 130, and the assembly ends of the upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120 are coupled with the corresponding slide rails 1301 and 1302 in a slidable manner to achieve position limiting and sliding on the slide rails 1301 and 1302. Preferably, the slide rail includes two parallel slide bars with a gap, and the side of the slide bar is provided with key slots 1303 and 1304, and the assembly ends of the upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120 are arranged between the two slide bars and key bodies 1101, 1102, 1201, 1202 are provided on both sides, and the position limiting and sliding on the slide rails 1301 and 1302 are achieved by the key bodies cooperating with the key slots 1303 and 1304 on the two slide bars.

[0032] In some embodiments, the control circuit is disposed on a PCB board 150, and the PCB board 150 is fixed in the lower shell 130; the PCB board 150 is powered by a power supply to control the operation of the electrical stimulation generator and the heating sheet, and adjust the heating temperature and the intensity and frequency of the electrical stimulation to meet the treatment needs of different patients.

[0033] In a preferred embodiment, the electrical stimulation area of ​​the lower tarsal plate heating electrode sheet 120 contacts the eyelid through the hydrogel material, which acts as a medium to evenly conduct the electrical stimulation signal to the orbicularis oculi nerve, thereby inducing blinking movement.

[0034] In the meibomian gland treatment device of the present invention, the upper tarsal plate heating sheet is used to heat the upper eyelid and soften the meibum in the upper meibomian gland; the lower tarsal plate heating electrode sheet has both heating and electrical stimulation functions, and its electrical stimulation area is preferably in contact with the eyelid through a hydrogel material to evenly conduct electrical stimulation signals to the orbicularis oculi nerve to induce blinking movements. The meibum is softened by heating, and the interaction between the eyeball and the eyelid during blinking generates pressure, which promotes the discharge of meibum and unclogs the meibomian gland channel. The device is equipped with a control circuit that can accurately adjust the heating temperature and the intensity and frequency of electrical stimulation to meet the treatment needs of different patients.

[0035] The specific embodiments of the present invention are further described below.

[0036] See also Figures 1A to 5 A meibomian gland therapeutic device includes an upper tarsal plate heating sheet 110, a lower tarsal plate heating electrode sheet 120, a lower shell 130 and an upper shell 140, a chip 150 and a battery 160. The lower shell 130 is provided with a slide rail 1301 coupled with the upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120, a key slot 1303 of the slide rail 1302, and a key slot 1304 cooperates with two key bodies 1101, 1102 of the upper tarsal plate heating sheet and two key bodies 1201, 1202 of the lower tarsal plate heating electrode sheet to form a limit. The battery 160 is directly embedded in a battery slot 1305, the chip 150 is connected to the lower shell 130 by four stacked screw holes 1306, and the four symmetrical screw holes 1307 of the lower shell 130 are connected to the upper shell 140 by four symmetrical screw holes 1401.

[0037] like Figure 1A and Figure 1B As shown, the structure includes an upper tarsal plate heating sheet 110, a lower tarsal plate heating electrode sheet 120, a lower shell 130 and an upper shell 140, a chip 150 and a battery 160, and the structure is a left-right symmetrical structure.

[0038] like Figure 2 As shown, the lower tarsal plate heating electrode sheet 1203 area is the heating area, and the area 1204 is the electrical stimulation area. The hydrogel will be adhered to the area 1204 to apply electrical stimulation, and there are keys 1201 and 1202 at the rear end.

[0039] like Figure 3 The upper tarsal plate heating sheet shown only has the function of heating the upper tarsal plate, and has keys 1101 and 1102 at the rear end.

[0040] like Figure 4The lower housing 130 shown in the figure comprises a slide rail 1301 and a slide rail 1302, and the side of the slide rail is provided with a key slot 1303 and a key slot 1304. A battery slot 1305 and four symmetrical screw holes 1306 are provided, and the edge of the lower housing 130 is provided with four symmetrical screw holes 1307. A battery charging interface 1308 is provided on the side.

[0041] like Figure 5 The group structure of the upper tarsal plate heating sheet 110, the lower tarsal plate heating electrode sheet 120, the lower shell 130, the chip 150 and the battery 160 is shown. The keys 1201 and 1202 of the lower tarsal plate heating electrode sheet 120 and the key slot 1304 of the lower shell 130 form a key connection and cooperate, and together with the slide rail 1302, form a limit, so that the lower tarsal plate electrode sheet 120 can slide one-dimensionally on the slide rail within a certain range. The keys 1101 and 1102 of the upper tarsal plate heating sheet 110 and the key slot 1303 of the lower shell 130 form a key connection and cooperate, and together with the slide rail 1301, form a limit, so that the upper tarsal plate electrode sheet 110 can slide one-dimensionally on the slide rail within a certain range. The battery 160 is adapted to the battery slot 1305 of the lower shell, and is directly embedded and assembled. The charging port 1308 is adapted to the battery charging interface 1601, and the matching relationship between the two is concentric. The chip 150 and the four symmetrical screw holes 1306 are connected by bolts.

[0042] See also Figure 2 The upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120 both have a heating function. The controller sends a heating signal to the heater, and the heater heats the upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120 to increase the temperature. The upper tarsal plate heating sheet 110 and the lower tarsal plate heating electrode sheet 120 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. After heating and softening, the lower tarsal plate heating electrode sheet 1204 area is an electrical stimulation area, which will generate electrical stimulation to the nerves under the lower tarsal plate, so that the orbicularis oculi muscle is stimulated to strongly contract, and the contracted orbicularis oculi muscle will form pressure on the meibomian gland together with the eyeball, prompting the meibum in the meibomian gland to be squeezed out.

[0043] The use of the meibomian gland therapeutic device can achieve rhythmic contraction and relaxation of the orbicularis oculi muscle by electrically stimulating the orbicularis oculi nerve, thereby causing rhythmic blinking of the eyelids. During the treatment process, an electric current of a specific waveform is generated by the electric stimulation generator, and the current is evenly transmitted to the orbicularis oculi nerve through the conductive sheet and disposable treatment consumables, thereby inducing blinking movements with a specific rhythm. In this state, the outward pressure of the eyeball during blinking simulates the meibomian gland massage action, squeezes out the melted meibum, and thus unclogs the meibomian gland channel, achieving a therapeutic effect on meibomian gland disorders. Furthermore, the meibomian gland therapeutic device is provided with a heating mechanism, which fully heats the upper and lower eyelids to 42.5°C by contact before applying electrical stimulation, melts the solidified meibum in the patient's meibomian glands, and has a better therapeutic effect.

[0044] The embodiment of the present invention is a meibomian gland therapeutic device based on electrical muscle stimulation, including a therapeutic device body, a heating mechanism, an electrical stimulation generator, a conductive sheet, disposable therapeutic consumables, a power supply, and a PCB board. When in use, this product is worn around the patient's head, and the upper tarsal plate heating sheet and the lower tarsal plate heating sheet are respectively pasted on the corresponding eyelid areas of the patient. The device is started by the button on the shell. The heating temperature and the intensity and frequency of the stimulation current can be adjusted by the button. Heating by the heating sheet can promote the melting of meibum in the tarsal plate, and then the effect of rapid blinking can be achieved through electrical stimulation. The patient squeezes out the meibum through blinking movements. The electrical stimulation scheme of the meibomian gland therapeutic device has the advantages of simple and reliable structure, no need for anesthetics, and easy operation. Patients can perform treatment at home by themselves.
