Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of eye massagers, in particular to an eye massager for dry eye. BACKGROUND

[0002] Dry eye is a common eye disease, one of the main causes of which is meibomian gland dysfunction (MGD), leading to excessive tear evaporation. Clinical studies have shown that constant temperature hot compress and physical massage of the eyelid are effective physical therapies for MGD dry eye. Hot compress can melt the solidified lipids that block the meibomian glands, while massage can promote the excretion of the melted lipids, restoring gland function.

[0003] Currently, there are mainly two forms of devices on the market that implement this therapy: handheld massagers: such devices are usually operated by doctors, although they have a certain degree of flexibility, the treatment effect is highly dependent on the skill and experience of the operator, and it is difficult to standardize. At the same time, hand-held operation is easy to cause fatigue, and it is difficult to maintain a stable position and pressure during treatment, affecting the consistency of the treatment effect. Table-type massage devices: such devices usually use pneumatic power devices to provide massage power, and integrate hot compress functions. Although it solves the problem of standardization of operation, it has a large volume and complex structure, and needs to be connected to a table-type main machine and an air pipe, which makes the device inconvenient to move and has poor flexibility, and is only limited to use in hospitals or clinics, so patients cannot perform convenient home treatment. In addition, the treatment head (massage head and heater) of the existing device is usually a fixed integrated design, which cannot be accurately adjusted according to the eye physiological structure (such as interpupillary distance and eyelid thickness) of different patients. This may cause uneven distribution of treatment pressure, inaccurate hot compress position, and even continuous pressure on the eyeball sclera, causing poor comfort and safety risks.

[0004] In summary, the existing technology has the contradiction between the portability of the device and the effectiveness and safety of the treatment, as well as the contradiction between standardized treatment and individualized adaptation. Therefore, there is an urgent need in the field for an integrated dry eye treatment device that is portable, safe, and can adapt to different patient eye characteristics, to be suitable for clinical and home scenarios, and to improve the treatment experience and effect.

The eyecup body 1 is further provided with a pupil distance adjustment mechanism, and the pupil distance adjustment mechanism is used for adjusting the position of the eyelid heater 2 and the massage mechanism in the horizontal direction to adapt to the pupil distance of different users.

[0039] The dry eye treatment instrument provided by the embodiment of the present application is safe, comfortable, accurate and highly adaptable.

[0040] To sum up, the dry eye treatment instrument provided by the embodiment of the present application solves the technical problems of the prior art, such as heavy equipment, inconvenient operation, potential safety hazards and uneven treatment effect caused by individual differences, and provides a safe, comfortable, accurate and highly adaptable dry eye treatment instrument.

[0041] In an alternative embodiment, the gap distance is 2-5 mm.

[0042] Please refer to Figures 6-7 In an alternative embodiment, the pupil distance adjustment mechanism comprises a pupil distance adjustment knob 10 and a screw rod 18.

[0043] The pupil distance adjustment knob 10 is rotatably arranged on the eye mask body 1. The screw rod 18 is coaxially fixed with the pupil distance adjustment knob 10. At least one pupil distance adjustment block 17 is internally provided with a threaded hole matched with the screw rod 18 or a slider structure linked with the screw rod. The rotation of the pupil distance adjustment knob 10 can drive the pupil distance adjustment block 17 to move in the horizontal direction towards or away from each other, thereby driving the eyelid heater 2 and the massage mechanism fixed thereon to move synchronously.

[0044] As shown in Figures 1-3 First, the heating module 3 of the eyelid heater 2 is placed between the eyelid 6 and the sclera 7 of the dry eye patient, as shown in Figure 3The clamping block 14 of the eyeshade body 1 is pushed to the open state, the interpupillary distance adjusting knob 10 is rotated to move the interpupillary distance adjusting block 17 relatively, so as to adapt to the interpupillary distance of different patients, the eyeshade body 1 is worn on the head of the patient, the eyelid heater 2 is passed through the limiting groove 16 of the eyeshade, and the eyeshade is fixed to the head of the patient by the headband 13. The main structure of this part is that the interpupillary distance adjusting knob 10 is fixed relative to the screw rod 18, the rotation of the interpupillary distance adjusting knob 10 drives the screw rod 18 to rotate, the sliding groove 19 has a corresponding thread matched with the screw rod 18, the rotation of the screw rod 18 drives the sliding groove 19 to move up and down, the long hole on the sliding groove 19 is matched with the cylinder on the interpupillary distance adjusting block 17, so that the up-and-down movement of the sliding groove 19 drives the left-and-right movement of the interpupillary distance adjusting block 17, so as to realize the adjustment of the interpupillary distance.

[0045] In an alternative embodiment, the eyeshade body 1 comprises an upper shell 8 and a lower shell 9 which are relatively movable, the lifting mechanism is arranged on the lower shell 9 and is drivingly connected to the upper shell 8, and the interpupillary distance adjusting mechanism, the eyelid heater 2 and the massage mechanism are arranged on the upper shell 8.

[0046] In an alternative embodiment, the lifting mechanism comprises: The lifting knob 12 is rotatably arranged on the outside of the eyeshade body 1; The transmission assembly converts the rotary motion of the lifting knob 12 into linear motion; The transmission assembly is connected to the upper shell 8 and is used to drive the upper shell 8 to move upward by a gap distance relative to the lower shell 9, so as to carry the eyelid heater 2 and the massage mechanism.

[0047] Please refer to Figures 8-11 In an alternative embodiment, the transmission assembly comprises a bevel gear shaft 26, a worm shaft 27 and a worm wheel shaft 28. The bevel gear shaft 26 is fixedly connected to the lifting knob 12. The worm shaft 27 is provided with a bevel gear meshing with the bevel gear shaft 26. The worm wheel shaft 28 is meshed with the worm on the worm shaft 27. The top end of the worm wheel shaft 28 is provided with a screw rod, and the nut seat 20 matched with the screw rod is fixed in the upper shell 8. The rotation of the worm wheel shaft 28 drives the nut seat 20 and the upper shell 8 to move linearly.

[0048] Exemplarily, rotating the lifting knob 12 on the eyecup body 1 causes the upper shell 8 of the eyecup body 1 to lift the eyelid heater 2 by 3 mm, so that the eyelid heater 2 is separated from the eyeball sclera 7 by a certain gap, thereby reducing the pressure on the sclera. The lifting knob 12 is fixed to the bevel gear shaft 26, and rotating the lifting knob 12 drives the bevel gear shaft 26 to rotate. The bevel gear shaft 26 has two bevel gears that cooperate with the bevel gears on the worm shaft 27, thereby driving the worm shaft 27 to rotate. The worm shaft 27 drives the worm gear shaft 28 to rotate through the worm above. The worm gear seat 29 is fixed to the lower shell 9, and the worm gear shaft 28 can rotate in the worm gear seat 29. The top end of the worm gear shaft 28 has a screw rod that cooperates with the thread on the nut seat 20 in the upper shell 8. Therefore, the rotation of the worm gear shaft 28 drives the nut seat 20 and the upper shell 8 to move upward, thereby driving the eyelid heater 2 to move upward. The lower shell 9 has four sliding sleeves 35 that cooperate with the sliding columns 37 on the upper shell to slide relative to each other.

[0049] In an alternative embodiment, the eyecup body 1 is provided with a slidable clamping block 14 that has an open state and a closed state. When the clamping block 14 is in the open state, the eyelid heater 2 can be placed through the limiting slot 16 on the eyecup body 1. When the clamping block 14 is in the closed state, the elastic needle 15 on the clamping block 14 contacts the contact 5 on the eyelid heater 2 to achieve electrical connection, and at the same time, the clamping block 14 locks the eyelid heater 2 on the pupil distance adjusting block 17.

[0050] Exemplarily, the clamping block 14 can be pushed to the closed state. The elastic needle 15 on the clamping block contacts the contact 5 on the eyelid heater, thereby enabling the electrical control unit inside the eyecup body 1 to communicate with the eyelid heater 2, and enabling the temperature of the heating module 3 of the eyelid heater 2 to be controlled. At the same time, the engagement teeth 23 on the pupil distance adjusting block 17 cooperate with the engagement teeth 4 on the eyelid heater 2, thereby fixing the eyelid heater 2 to the pupil distance adjusting block 17. The pupil distance adjusting block 17 is provided with a small sliding rail 22, and the clamping block 14 can slide in the small sliding rail 22. The clamping block 14 is provided with a limiting bead 24, and the limiting bead 24 is provided with a spring below to keep the limiting bead in the ejected state. The limiting bead can be clamped into the limiting slot 25 of the pupil distance adjusting block 17, thereby enabling the clamping block 14 to remain in the open and closed states.

[0051] Further, the rear end of the elastic needle 15 is connected to the electrical control unit fixed in the eyecup body 1 through a flexible wire (such as an FPC wire or a thin wire bundle). The current is transmitted from the electrical control unit to the elastic needle 15 through the wire, and is transmitted to the circuit inside the eyelid heater 2 through the physical contact between the elastic needle 15 and the contact 5, and finally powers the eyelid heating module 3 and causes it to heat up.

[0052] To ensure reliable electrical connections and prevent short circuits, the clamping block 14 has internal grooves for fixing and insulating wires, and the spring pin 15 is fixed to the clamping block 14 by an insulating sleeve. An insulating area is also provided around the contact point 5 of the eyelid heater 2.

[0053] Please see Figures 12-14 In one alternative implementation, the massage mechanism includes: Motor 32 is fixedly mounted on clamping block 14; Gear 39 is mounted on the output shaft of motor 32; The massage head holder 33 is provided with a rack 36 that meshes with the gear 39; The silicone massage head 34 is detachably mounted on the massage head holder 33; Among them, the motor 32 drives the massage head holder 33 and the silicone massage head 34 to reciprocate linearly in a direction perpendicular to the eyelid through the cooperation of the gear 39 and the rack 36.

[0054] For example, pressing the treatment switch 11 powers the electrical control unit to the eyelid heater 2, causing the heating module 3 of the eyelid heater 2 to heat up to the set temperature and maintain it. Simultaneously, the motor drives the massage mechanism downwards until the massage block contacts the eyelid. After the force sensor 38 detects the set force, the mechanism moves back until the sensor detects zero force. This up-and-down reciprocating motion, according to the set frequency and force, massages the eyelid. The force sensor 38 is installed inside the silicone massage head 34, which can be removed, disinfected, and reused. The motor 32 is mounted on the clamping block 14, and a gear 39 is mounted on the motor output shaft. A rack 36 is mounted on the massage head holder 33 and cooperates with the gear 39. The small sliding sleeve 35 on the massage head holder 33 cooperates with the small sliding column 37 on the interpupillary distance adjustment block 17 to slide, thereby converting the rotation of the motor 32 into the reciprocating linear motion of the massage head holder 33. The silicone massage head 34 is mounted on the massage head holder 33, and the eyelid is between the silicone massage head 34 and the eyelid heater, so that the eyelid is massaged by the silicone massage head 34 while being heated.

[0055] In one alternative embodiment, a force sensor 38 is provided inside the silicone massage head 34, and an electrical control unit is signal-connected to the force sensor 38 and the motor 32, and is configured as follows: The control motor 32 drives the silicone massage head 34 to move downwards until the force sensor 38 detects that the preset force value has been reached; Then, control motor 32 to reverse, driving silicone massage head 34 to move upward until force sensor 38 detects zero force. Repeat the above process, performing a reciprocating massage at a preset frequency and intensity.

[0056] In an alternative embodiment, a linkage sliding structure is provided between the massage head fixing frame 33 and the clamping block 14. The linkage sliding structure comprises a slide 40 and an air bag sliding block 42 provided on the massage head fixing frame 33, and an air bag sliding column 43 provided on the clamping block 14. The air bag sliding block 42 is slidably provided in the slide 40 and is sleeved with the air bag sliding column 43. The linkage sliding structure enables the massage mechanism to move with the clamping block 14 between the open and closed states, while the silicone massage head 34 can independently perform the reciprocating linear motion with the clamping block 14.

[0057] In order to ensure that the silicone massage head 34 moves up and down without affecting the treatment, a slidable air bag sliding block 42 is separately provided on the massage head fixing frame 33. The air bag sliding block 42 and the clamping block 14 are cooperated by a sliding sleeve sliding column. The slide 40 is provided on the massage head fixing frame 33, and the air bag sliding block 42 can slide between the massage head fixing frame 33 and the slide 40. The air bag sliding block 42 is provided with an air bag sliding sleeve 41, which cooperates with the air bag sliding column 43 on the clamping block 14. The two can slide up and down relative to each other, so that the air bag 34 can move with the clamping block 14, and the silicone massage head 34 can move up and down.

[0058] The linkage sliding structure enables the massage head fixing frame 33 and the clamping block 14 to be connected in a relative floating manner in the vertical direction. When the clamping block 14 moves horizontally between the open and closed states, the structure allows the silicone massage head 34 to move with it. During the treatment process, when the motor 32 drives the massage head fixing frame 33 to perform vertical reciprocating motion, the air bag sliding block 42 can freely slide in the slide 40, so that the vertical motion is independent of the clamping block 14 and does not interfere with each other.

[0059] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed methods and technical contents to obtain equivalent embodiments with equivalent changes, but as long as the changes do not deviate from the technical solution of the present application, any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the present application.
