Description

Eye cup and eye treatment device

Technical Field

The present invention relates to a mammalian ocular treatment device, and more particularly to an ocular cup for an ocular treatment device.

Background

In recent years, ocular fatigue causes an increase in ocular secretions, and ocular diseases occur year by year without paying attention to the causes such as ocular hygiene. Especially, the incidence rate of xerophthalmia is increasing in China, and the xerophthalmia is one of the most common ocular diseases. Dry eye, also known as keratoconjunctival dryness, refers to a general term for various diseases characterized by abnormal tear quality or quantity, or decreased tear film stability due to abnormal kinetics, accompanied by ocular discomfort or damage to ocular surface tissue. The patients mainly show dry eyes, foreign body sensation, burning sensation, photophobia, blurred vision and asthenopia.

For xerophthalmia, a relatively effective treatment method is physical treatment, such as hot compress, massage and the like, and has extremely important effect on improving symptoms of patients on the basis of drug treatment. The hot compress can melt the abnormal coagulated meibomian gland secretion so as to achieve the effect of dredging the meibomian gland discharge channel, and the massage can squeeze out the lipid secretion stored in the meibomian gland, so that the medical community commonly considers three major bases of dry eye physiotherapy as hot compress, squeezing and cleaning.

Other ocular disorders besides dry eye, such as chronic inflammation and pain, aragonia, chronic blepharitis, demodex blepharitis, iridocyclitis, asthenopia, etc., may also be treated by means of hot compress.

At present, the instruments are widely used for the physical treatment of the eye diseases in foreign countries such as the United states, europe and the like, and are extremely representative of the research and development of TearScience company in the United statesThe meibomian gland thermal artery instrument comprises a thermal artery exciting head and a temperature and pressure control system, wherein the thermal artery exciting head consists of a heater and an eye cup, a gap is reserved between the eye cup and the heater, insulation materials are filled for heat insulation so as to avoid damaging cornea, a heating element and a temperature sensor are arranged on the convex part of the eye cup, and the meibomian gland can be heated once through the inner face of an eyelid within 12 min.

Such devices for the treatment of ocular disorders by means of hot compress are also emerging in China. During treatment, the patient closes eyes, the eye cup is attached to the eyelid for heating and hot compress, and the steps of extrusion, cleaning and the like are performed after the hot compress is completed.

However, the inventors have found that because of the high hygienic requirements of ocular treatment, optimally the treatment head, such as an eye cup, that contacts the patient's eyes needs to be replaced with a waste one each time it is used. Meanwhile, because the eyeball is fragile and sensitive, a high safety requirement is required for a hot compress device acting on the eye, in particular to a device which directly contacts the inner surface of the eyelid or is close to the eyeball.

The prior eye cup for directly heating the inner surface of eyelid is characterized in that a heating element and a temperature sensor are arranged on the convex part of the eye cup, and a gap is reserved between the heaters and is filled with insulating materials for heat insulation so as to avoid eye damage. Although the device has better treatment effect, because the heating element is arranged near eyes, irreversible damage is easily caused to eyes of patients, and meanwhile, high-specification precise control components are required to be used for guaranteeing safety, strict quality control is required, so that the parts of the eye cup are high in price and high in manufacturing cost, and the treatment cost of patients is high.

In another way, the eye cup is attached to the eyelid for heating and hot compress, and the eye cup is safe and cost-controllable because of being far away from the eyeball, but the eye cup is not directly acted on the inner face of the eyelid, so that the treatment effect is relatively poor.

Therefore, how to overcome the defects of the technology and provide an eye cup which can directly heat the inner surface of the eyelid to strengthen the treatment effect; on the other hand, the temperature can be effectively controlled, and the damage to eyes caused by treatment can be avoided in the process of over-treatment of eyes; on the other hand, the reduction of the manufacturing cost is a technical problem to be solved by the person skilled in the art.

In order to achieve the above object, the present invention provides an eye cup.

Referring first to fig. 1, 2 and 3, fig. 1 is a perspective view of an eye cup in accordance with an embodiment of the invention; FIG. 2 is a cross-sectional view of an eye cup in accordance with an embodiment of the invention; fig. 3 is a schematic view of an eye treatment device according to an embodiment of the invention.

In the embodiment of fig. 1, 2, the eye cup 1 comprises a liquid inlet channel 13, a liquid outlet channel 14 and a cup-shaped portion 10. The cup portion 10 is positioned between the patient's eyelid (upper and lower eyelid indicated by reference numerals 221 and 222 with reference to fig. 3) and the patient's eyeball (reference numeral 21 with reference to fig. 3). The cup-shaped portion 10 of the eye cup 1 comprises a first side 101 and a second side 102. The first side 101 is curved in contour toward the patient's eyelids 221 and 222 to conform to the inner face of the eyelids. The second side 102 faces the eyeball 21 of the patient, and is opposite to the first side 101, and is shaped like an inward concave arc so as to be attached to the eyeball.

Specifically, as shown in fig. 3, when the cup-shaped portion 10 is positioned between the patient's eyelids 221 and 222 and the patient's eyeball 21, the first side 101 contacts the inner faces of the patient's eyelids 221 and 222, and the second side 102 contacts the sclera of the patient's eyeball 21, while the second side 102 avoids direct contact with the cornea of the patient's eyeball 21 so as not to damage the cornea.

The cup portion 10 of the eye cup 1 has a cavity 12. The liquid inlet channel 13 communicates with the cavity 12 to supply liquid to the cavity 12. A liquid outlet channel 14 communicates with the cavity 12 for withdrawing liquid from the cavity 12. The cavity 12 of the cup-shaped portion 10 is in communication with only the liquid inlet tube 13 and the liquid outlet tube 14, and the inside of the cavity 12 of the cup-shaped portion 10 is not in communication with the outside, so that the liquid in the cavity 12 of the cup-shaped portion 10 does not contact the patient's eyelids 221 and 222 and the patient's eyeball 21.

In operation, liquid flows through the cavity 12 of the cup-shaped portion 10 via the liquid inlet channel 13 and the liquid outlet channel 14, and the temperature of the liquid is controlled 31 by the temperature control device. The liquid is used as a heating medium or a cooling medium in the cavity 12 of the cup-shaped portion 10, and can heat or cool the cup-shaped portion 10. Since the temperature of the liquid can be precisely controlled by the temperature control device 31, the working temperature of the cup-shaped part can be precisely regulated and controlled, and experiments prove that the precision can reach plus or minus 0.5 ℃.

The temperature change of the first side 101 is greater than the temperature change of the second side 102 when the liquid is within the cavity 12.

In some embodiments, the eye treatment device has only a heating (fomentation) function. The liquid flows into the cavity 12 of the eye cup 1 after being heated by the temperature control device 31, and the heated liquid is heated towards the first side 101 of the eyelid to reach a relatively high working temperature by controlling the flow of the liquid in the cavity 12, so that the purpose of effectively dredging the meibomian glands is achieved, and meanwhile, the second side 102 is controlled at a relatively low working temperature, so that the purpose of protecting the eyeballs is achieved.

In other embodiments, the ocular management device also has a refrigeration (cold compress) function. The liquid flows into the cavity 12 of the eye cup 1 after being refrigerated by the temperature control device 31, and the first side 101 is refrigerated to reach a relatively low working temperature by the contact heat conduction of the liquid and different sides so as to realize the therapeutic effect of sedation and anti-inflammation, and meanwhile, the second side 102 is controlled at a relatively high working temperature so as to achieve the purposes of avoiding damage and stimulating eyeballs.

Fig. 4a is a schematic structural view of a cup portion according to an embodiment of the present invention. Referring to fig. 4a, the liquid inlet channel 13 is provided with a first port 131 at one end and a second port 132 at the opposite end. The first port 131 is connected to an external liquid pipe. The second port 132 is connected to the cavity 12, and the second port 132 is disposed relatively close to the first side 101 and far from the second side 102. When the liquid flows into the cavity 12, it first exchanges heat with the first side 101 and delays exchanging heat with the second side 102.

To control the flow of liquid within the cavity 12, a space 161 is provided within the cavity 12 to block the flow of liquid to the second side 102, allowing the liquid to exchange heat with the first side 101 for a longer period of time.

In this embodiment, the space 161 is a thin film layer, and the space 161 divides the cavity 12 into the first cavity 121 and the second cavity 122. In positional relationship, the first side 101 is located on one side of the first cavity 121, the second cavity 122 is located on the opposite side of the first cavity 121, i.e., the first cavity 121 is proximate to the first side 101, and the second cavity 122 is proximate to the second side 102. The second port 132 of the feed channel 13 is connected to the first cavity 121 such that liquid first flows into the cavity 121 and exchanges heat with the first side 101. The space 161 may be made of a material having low water permeability such that the space 161 blocks the flow of liquid to the second side 102 such that the liquid stays in the first cavity 121 for a longer period of time to exchange heat with the first side 101 such that the first side 101 is rapidly warmed or cooled and the second side 102 has a smaller temperature change than the first side 101. One end of the liquid outlet channel 14 is provided with a third port 141, and the opposite end is provided with a fourth port 142, the third port 141 is connected with an external liquid pipe, and the fourth port 142 is communicated with the first cavity 121 for extracting liquid from the first cavity 121.

In a variant embodiment, as shown in fig. 4b, the tapping channel 14 is connected simultaneously with the first cavity 121 and the second cavity 122. Specifically, the liquid outlet channel 14 is provided with a third port 141 at one end, a fourth port 142 at the opposite end, and a fifth port 143. The third port 141 is connected to an external pipe. The fourth port 142 is connected to the first cavity 121 and the fifth port 143 is connected to the second cavity 122. In use, liquid residing in the first cavity 121 and liquid residing in the second cavity 122 are simultaneously pumped out of the cavity 12. Such an arrangement allows liquid to be sucked out of both cavities faster and more evenly than if ports were provided in only the first cavity 121 or only the second cavity 122, increasing the flow rate of the liquid and facilitating an increase in the accuracy of the tempering.

Fig. 4c is a schematic structural view of a cup portion according to another embodiment of the present invention. As shown in fig. 4c, the port of the inlet channel 13 connected to the cavity 12 is also disposed relatively close to the first side 101 and far from the second side 102.

In this embodiment, the hollow cavity 12 is provided with a plurality of spaces 162, and the plurality of spaces 162 are staggered, so that the liquid flowing in from the liquid inlet channel 13 is blocked from flowing to the second side 102 and is retained near the second side 101 for a longer time, so that the liquid and the first side 101 perform sufficient heat exchange, and further the temperature change of the first side 101 is greater than the temperature change of the second side 102. The plurality of spacers 162 may be connected to the first side 101 by means of welding. Preferably, the plurality of spacers 162 may be made of the same material as the first side 101 and formed by injection molding integrally with the first side 101, thereby further reducing the cost and the processing difficulty.

Fig. 4d is a schematic structural view of a cup portion according to another embodiment of the present invention. As shown in fig. 4d, a packing region 17 is provided in the cavity 12, and packing is arranged in the packing region 17. The port 132 of the feed channel 13 connecting with the cavity 12 is arranged above or in the upper part of the packing area 17. The packing region 17 is disposed relatively close to the first side 101 and remote from the second side 102. When liquid flows into the cavity 12 through the port 132 of the liquid inlet channel 13, heat exchange is performed with the first side 101 and flows into the packing region 17, and the flow speed of the liquid in the packing region 17 is slowed down, so that the liquid stays in the packing 17 for a certain time, and heat exchange with the first side 101 is further increased, and heat exchange with the second side 102 is delayed and reduced.

The filler is made of a material which does not react with the liquid. Preferably, a material of high thermal conductivity is used for the filler material, so that the liquid, after passing through the filler material, exchanges heat with the filler material to a certain extent, further reducing the heat exchange with the second side 102.

In other embodiments, a diversion channel may also be provided in the cavity such that liquid directed into the cavity is retained in the diversion channel, reducing heat exchange with the second side 102.

In addition to the fact that the temperature change of the first side 101 is greater than the temperature change of the second side 102 by controlling the flow of liquid within the cavity 12, an insulating layer may be provided between the cavity 12 and the second side 102 in some embodiments to avoid direct heat exchange between the liquid and the second side 102 and thereby facilitate temperature control of both sides.

Preferably, the first side 101 is made of a high thermal conductivity material and the second side 102 is made of a low thermal conductivity material, so that heat exchange between the first side 101 and the liquid is increased and heat exchange between the second side 102 is reduced.

In practice, the above technical means or the combination of technical means can effectively realize that the temperature change of the first side 101 is larger than the temperature change of the second side 102 when the liquid is in the cavity 12, so that the ideal treatment effect is realized on the premise of not stimulating and damaging the eyeball to ensure the safety.

When the eye treatment device works in the hot compress mode, the working temperature range of the first side face 101 of the eye cup 1 is 40-45 ℃, and the working temperature range of the second side face 102 is less than 40 ℃.

When the eye treatment device works in the cold compress mode, the working temperature range of the first side face 101 of the eye cup 1 is 0-20 ℃, and the working temperature range of the second side face 102 is more than 25 ℃.

The eye cup provided by the invention directly acts on the inner surface of the eyelid, realizes the temperature change of the eye cup by arranging the cavity to circulate through the liquid as a medium, realizes accurate time control and temperature control, and avoids the danger and negative effect of directly arranging a heating element on the eye cup.

The eye cup provided by the invention further ensures that eyeballs are not damaged or stimulated during treatment and improves the treatment effectiveness by controlling different working temperatures of different sides.

The eye cup provided by the invention does not comprise sensing and heating components, only the mechanical structure arrangement and the material selection realize the safety and the treatment effectiveness, greatly reduce the cost, realize the miniaturization of the eye cup and realize the economic feasibility that the eye cup can be used as a disposable replacement component. In some embodiments, one or more of the cup-shaped portion, the liquid inlet channel and the liquid outlet channel are arranged to be separated from the eye cup individually or in a complete set for replacement, so that only the cup-shaped portion can be replaced or the cup-shaped portion can be sleeved with the liquid inlet channel and the liquid outlet channel, thereby further reducing the cost.

In some embodiments of the invention, the eye cup 1 comprises a grip 15 connected to the second side 102. The grip portion 15 is convenient for a healthcare worker to manipulate to position the cup portion 10 of the eye cup 1 between the patient's eyelids 221 and 222 and the patient's eyeball 21.

In the above embodiment, the eye cup may further include a pressing unit. A pressing unit is connected to the grip 15, and is located outside the patient's eyelids 221 and 222 to provide pressing force to the patient's eyelids 221 and 222 outside the patient's eyelids 221 and 222 when the cup part 10 of the eye cup 1 is positioned between the patient's eyelids 221 and 222 and the patient's eyeball 21. Thereby, squeezing and massaging of the patient's eyelids 221 and 222 can be achieved by the squeezing unit.

Other connection means are also within the scope of the present invention. The shaped portion 3112 is provided with an air inlet 3113 and a connecting tongue 3114.

Specifically, the structure of the airbag 321 is described above as an example. The structure of the lower bladder 322 may be similar to that of the upper bladder 321 and will not be described again. The upper balloon 321 includes a second connection portion 3211 and a balloon portion 3212 (similarly, the lower balloon 322 includes a second connection portion 3221 and a balloon portion 3222).

The upper and lower air cells 321 and 322 may be made of a silicon material so that the size of the air cell portion 3212 thereof can be controlled by gas.

Specifically, with continued reference to fig. 3, the squeezing unit may be connected to the gas control device 33 so that the upper and lower air bags 321 and 322 are inflated and pressure-controlled by the gas control device 33, thereby achieving control of squeezing and massaging of the patient's eyelids 221 and 222.

The invention also provides an eye treatment device which comprises the eye cup in the embodiment.

Referring to fig. 3, in some embodiments, the ocular treatment device further comprises a fluid control device, a temperature control device, and a controller.

The liquid control device is connected to the liquid inlet channel 13 and the liquid outlet channel 14 for supplying liquid to the liquid inlet channel and recovering the liquid from the liquid outlet channel. In some embodiments of the invention, the liquid control device may be a negative pressure device 32. A negative pressure device 32 is connected to the outlet pipe 14 to provide negative pressure to the outlet pipe 14 to perform a pumping function for the outlet pipe 14 to pump the liquid from the cavity 12.

And the temperature control device is connected with the liquid control device to provide liquid with set temperature. In some embodiments of the present invention, the temperature control device 31 may include a semiconductor cooling fin, a temperature sensor, and a temperature control module. The semiconductor refrigerating sheet is used for adjusting the temperature of the liquid input to the liquid inlet pipe. In a specific implementation, the eye treatment device provided by the invention can realize refrigeration and heating, so that the semiconductor refrigeration piece just completes the two temperature regulation modes (by changing the current direction and then changing the heat flow direction). The temperature sensor is used for sensing the temperature of the liquid. The temperature control module is used for receiving the temperature sensed by the temperature sensor and providing temperature control parameters for the semiconductor refrigeration piece according to the sensed temperature and the target temperature, so that the semiconductor refrigeration piece adjusts the temperature of the liquid input into the liquid inlet pipe to the target temperature. The temperature control module is a bidirectional temperature control module, so that the function can be automatically completed. Specifically, the relative voltage value between two TECs on the temperature control module can be set to be positive/negative according to the temperature regulation requirement, so that the relative voltage of the two leads of the TEC is changed, different temperature control modes are realized, and a user does not need to change the wiring direction when the ambient temperature is changed.

Therefore, in the embodiment, the user can realize temperature control only by setting the initial parameters and the target temperature, and the user does not need to participate in the temperature control process at any time.

In some embodiments of the present invention, the temperature control parameter is a dc voltage, and the temperature control module includes a voltage converter for converting a power supply voltage of the temperature control device into a dc voltage required by the semiconductor refrigeration sheet.

Further, the temperature control device 31 may further include a heat dissipation module to facilitate heat dissipation from the temperature control module.
