Description

Intraocular pressure regulating device including a pressure regulating member

The present invention relates to an intraocular pressure regulating apparatus, and more particularly, to an intraocular pressure regulating apparatus mounted adjacent to the eyeball.

In patients with glaucoma, which is not controlled by intraocular pressure-lowering drugs, the intraocular pressure is reduced by making a bypass so that the aqueous humor flows out of the conjunctiva outside the eye.

Glaucoma filtration, which produces a bypass or fistula for water leakage, may fail to control intraocular pressure due to a decrease in waterproof leakage due to closure of the bypass again after surgery. If primary surgery fails and glaucoma filtration is performed again, the incidence of bypass closure after surgery increases and the success rate is very low.

Depending on the type of glaucoma, so-called refractory glaucoma, such as neovascular glaucoma or secondary glaucoma due to uveitis, has a poor turnover closure after glaucoma filtration.

As described above, in the case of eyes or refractory glaucoma that have failed glaucoma filtration, surgery to install a glaucoma outflow device is performed to prevent the closure of bypass and to increase the success rate. The glaucoma outflow device is made of a tube that acts as a path for the eye's waterproofing out of the eye in front of the eye, and a small disc or membranous artefact that creates a space for the water to temporarily gather under the subconjunctival or tenon sac.

Molteno implants, introduced in 1968, are the first to be used. Later, Krupin-Denver implants, Baerveldt implants, and Ahmed implants have been developed and used. Almost all of them use silicon (silicone) as a material. Each implant uses a silicone tube as a waterproof drain passage without exception, and the size of the tube is similar to each other, with an outer diameter of 640 μm and an inner diameter of 300 μm. Ahmed implants and Baerveldt implants are the most frequently used.

When the thickness of the tubes used in these implants is small, it acts as a resistance to waterproof outflow, which makes it difficult to effectively lower the intraocular pressure. On the contrary, when the thickness is increased, the intraocular pressure becomes too low due to too much waterproof outflow. In this case, the pressure inside the eyeball may be 5 mmHg or less. This can be very dangerous because you may lose sight. To prevent this, a valve device to control the outflow should be provided, or extra measures should be taken to prevent excessive spillage by inserting a wick into the tube temporarily or during surgery. Despite these measures, the prevention of hypotony is often unsuccessful.

Even after the implant is installed, various imaging evaluations may be necessary depending on the patient's condition. In particular, there are situations in which MRI is absolutely required for accurate diagnosis and treatment evaluation. Hypotony has solved the problem, but there are many prior arts that have problems using MRI because there is no choice but to use metal materials. In mounting the implant, it is important not to be restricted to the use of imaging equipment, especially MRI.

In addition, the tube of the implant according to the prior art is thick, so that the tube installed under the conjunctiva protrudes to the eyeball surface and the tube is exposed after a long time may cause a dangerous situation.

To prevent this, separate tissue should be used to cover the tube during surgery. It usually covers the donor dura, pericardium, fascia, or sclera tissue.

Therefore, in the case of an implant according to the prior art, there are many problems, and there is a need for a technique capable of solving the aforementioned problem according to the prior art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be construed as meanings and concepts consistent with the technical spirit of the present invention.

Throughout this specification, when a member is located "on" another member, this includes not only when one member is in contact with another member but also when another member exists between the two members.

Throughout this specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless otherwise stated.

1 is a schematic diagram showing a state in which the intraocular pressure control device according to an embodiment of the present invention is mounted on the eyeball, and FIG. 2 is a schematic diagram illustrating the intraocular pressure control device shown in FIG. 1.

Referring to these drawings, the intraocular pressure regulating device 100 according to the present embodiment may be configured to include an eyeball waterproof moving tube 110, an eyeball waterproof receiving part 120, and a pressure regulating member 130.

1, the eyeball waterproof moving tube 110, the eyeball waterproof receiving unit 120 and the pressure control member 130 is shown in a structure that can be separated, respectively, in some cases, the eyeball waterproof moving tube 110, eyeball The waterproof accommodating part 120 and the pressure regulating member 130 may be formed in an integrated tubular structure.

As shown in FIG. 1, the eyeball-proof moving tube 110 has a structure in which one end is in communication with the inside of the eyeball, and the other end is in communication with the eyeball waterproof receiving part 120. In this case, the eyeball waterproofing may be derived from the eyeball or introduced into the eyeball through the eyeball waterproofing moving tube 110. Therefore, the waterproof eye movement tube 110 is preferably a tubular structure in which the waterproof eye can flow.

The ocular waterproof accommodating part 120 may have a structure in which an ocular waterproof moving tube 110 is mounted at one side thereof, and a storage space for accommodating the ocular waterproof is provided therein.

The pressure regulating member 130 is mounted inside the eyeball waterproof receiving unit 120 or adjacent to the eyeball waterproof receiving unit 120, and adjusts the pressure applied to the eyeball waterproof receiving unit 120 to adjust the volume of the storage space. have.

Therefore, the intraocular pressure regulating device 100 according to the present embodiment including such a configuration can easily adjust the intraocular pressure by naturally adjusting the pressure inside the eye by the flow rate and flow of the eye waterproof produced from the inside of the eye.

In the following, each of the above-mentioned configuration will be described in more detail and the operating principle of the intraocular pressure control device 100 according to the present embodiment will be described.

As mentioned above, the eyeball-proof moving tube 110 is a tubular structure, and may have a radius r of a predetermined size and extend to a predetermined length L.

In this case, in order to smoothly flow the eyeball, the radius r and the length L of the eyeball-proof moving tube 110 should be limited within a specific numerical range.

If the radius (r) of the eyeball waterproof moving tube 110 is too small, the eyeball can not be leaked or introduced from the inside of the eyeball outside, the effect of the pressure control device 100 can not be expected.

Preferably, the radius r of the ocular waterproof moving tube 110 may be 0.1 to 0.9 mm, and the length L of the ocular waterproof moving tube 110 may be 15 to 35 mm.

At this time, the radius (r) value and the length (L) of the waterproof eye movement tube 110 is to be specified so that the steady-state value (dP) calculated by the following <Equation 1> is within the range of 0.001 to 0.005 mmHg. This is preferred.

<Equation 1>

In Equation 1, the Q value is the physiological waterproofing ability of the eye, and the μ value is the dynamic viscosity value of the waterproofing.

According to <Equation 1>, the physiological ocular waterproof production capacity (Q) is set to 2.5 μl / min, the dynamic viscosity value (μ) of the ocular waterproof is set to 0.00069, and the steady state value (dP) is 0.003. When it is set to mmHg, it can be seen that the radius (r) value of the waterproof eye movement tube 110 is 0.5mm, the length (L) value is preferably 25mm.

The above-mentioned radius (r) value and the length (L) of the waterproof eye tube 110 is just one example, and is not particularly limited.

Since the pressure inside the eye pressure = dP + pressure control member internal pressure is formed in a steady state (dP) value can be installed by adjusting the pressure of the pressure control member. If dP is formed near 0, it hardly disturbs the flow of the waterproof eyeball, and the dP value is greatly changed due to the manufacturing error of the waterproof eyeball tube or the swelling effect due to absorbing the waterproof eyeball during installation. It is possible to prevent and this is advantageous to control the intraocular pressure.

In some cases, the eyeball waterproofing tube 110 may be formed with a plurality of fine through-holes that can leak the eyeball to the outside.

In this case, when the flow rate of the eye waterproof flowing through the eye waterproof moving tube 110 is large, it is possible to reduce the flow rate of the eye waterproof through the fine through hole, and consequently the sudden intraocular pressure that may occur due to the flow of the eye waterproof The rise can be prevented.

On the other hand, as shown in Figure 2, the pressure regulating member 130 is mounted in the storage space of the eyeball waterproof receiving portion 120, it may have a structure that the volume is variable according to the pressure inside the eyeball waterproof receiving portion.

Specifically, if the minimum intraocular pressure target value for hypotony to be set to 8mmHg, the pressure regulating member 130 is a structure corresponding to the structure of the eyeball waterproof receiving portion 120, eyeball waterproof receiving portion 120 The volume of the pressure regulating member 130 before being mounted in the storage space of the) may be 100.5 to 101.5% of the volume of the eye waterproof receiving portion 120. This is because the pressure value of 8 mmHg corresponds to about 1% of the atmospheric pressure of 760 mmHg.

In addition, the eyeball waterproof accommodating part 120 may have a planar rectangular structure, and the pressure regulating member 130 may have a structure corresponding to that of the eyeball waterproof accommodating part 120.

More specifically, as shown in FIG. 2, the length of one side of the pressure regulating member 130 before being mounted in the storage space of the eyeball waterproof receiving part 120 is equal to that of the eyeball waterproof receiving part 120. It may be formed with a length of 100.5 to 101.5% compared to the length of one side.

At this time, the pressure adjusting member 130 may be increased or decreased in volume by the pressure in the eyeball waterproof receiving portion 120.

That is, when the pressure in the eyeball rises, the eyeballs stored in the eyeball flows to the eyeball waterproof receiving part 120, wherein the pressure regulating member 130 is in response to an increase in the pressure in the eyeball waterproofing part 120. As a result, the volume is reduced, and as a result, the pressure increase in the eye can be absorbed by expanding the space of the eye waterproof accommodating part 120.

In some cases, a plurality of first fine through holes 121 may be formed on the outer surface of the eyeball waterproof accommodating part 120 that may leak to the outside.

In this case, the pressure adjusting member 130 mounted inside the eyeball waterproof receiving unit 120 may vary in volume, and may seal or open the first fine through hole 121.

That is, when the flow rate of the eyeball waterproof rises rapidly and the pressure control member 130 does not absorb the pressure increase inside the eyeball, the eyeball waterproof may be discharged to the outside through the first fine through hole 121. As a result, even in the case of a sudden increase in pressure inside the eyeball, it can be effectively absorbed, thereby preventing an increase in intraocular pressure.

Therefore, as mentioned above, the volume of the pressure regulating member 130 is changed by the eye waterproof flowing through the eye waterproof moving tube 110, and thus the pressure inside the eye waterproof receiving portion 120 is a predetermined size. It can be kept constant at the pressure of.

Figure 3 is a schematic diagram showing an intraocular pressure control device equipped with an additional eye waterproof.

In some cases, as shown in FIG. 3, the eyeball waterproof includes a storage space in communication with the second fine through hole 124 and having an eye drop that leaks through the second fine through hole 124. The additional storage unit 123 may be further mounted.

In this case, when a large amount of waterproof eye is leaked, the additional waterproof eye can be additionally stored through the additional eye waterproof receiving unit 123, so that it can effectively cope with a sudden increase in intraocular pressure.

The position of the second fine through hole 124 communicating with the additional eye waterproof receiving part 123 may be a position farthest from the eye waterproof moving tube 110, as shown in FIG. 3.

Specifically, the eye waterproof is continuously introduced into the eye waterproof receiving unit 120, and the volume of the pressure regulating member 130 is reduced by the pressure of the eye waterproof, and accordingly the agent which is covered by the pressure regulating member 130 is removed. The first minute through hole 121 is exposed, and at this time, the waterproof eye may leak to the outside through the first minute through hole 121. When an excessively large amount of eye waterproof is introduced into the eye waterproof accommodating part 120, the volume of the pressure regulating member 130 is further reduced, and finally, the second fine penetrating communicated with the additional eye waterproof additional part 123. Sphere 124 is exposed, it is possible to block the pressure load added to the intraocular pressure control device 100 by discharging the excessively inflow of the eye waterproof to the additional eye waterproof receiving unit 123.

As a result, the intraocular pressure regulator 100 according to the present embodiment including the additional eye waterproof receiving unit 123 may effectively cope with intraocular pressure even when an excessive amount of eye waterproof is introduced. In this case, it is effective to make the size of the second fine through hole 124 connected to the additional eye waterproof receiving unit 123 as large as possible than the other first fine through holes 121.

It is preferable to form a plurality of third minute through holes 125 having a similar shape to the eyeball waterproof receiving part 120 in the eyeball waterproofing additional storing part 123.

FIG. 4 is a schematic view showing the case where the pressure regulating member is manufactured by incorporating one side surface of the eyeball waterproof receiving portion, and FIG. 5 is a cutaway view showing a state cut by the cutting surface A shown in FIG. 4. Is shown.

4 and 5, a method of manufacturing a pressure regulating member of an intraocular pressure regulating device according to the present invention will be described.

Pressure control member 130 is preferably composed of a flexible material that can be changed in volume by the pressure of the eye waterproof.

At this time, the eyeball waterproof receiving unit 120 may also be made of a flexible material, and in some cases it is made of a material having a higher strength than the pressure regulating member 130 can prevent damage to the intraocular pressure control device by the external force.

The above-mentioned pressure regulating member 130 may be manufactured separately from the eyeball waterproof receiving part 120 and mounted on the eyeball waterproof receiving part 120.

In some cases, as shown in Figures 4 and 5, it is possible to manufacture to have a volume of a predetermined size by incorporating one side of the eyeball waterproof receiving portion 120 and then bonded.

In this case, the bonding method may be exemplified by a method of thermal fusion, a method using an adhesive, a method using a fastening member, and the like.

In addition, as shown in Figure 6, the pressure regulating member 130 may be mounted to the eyeball waterproof receiving portion in the form of surrounding the outer surface of the eyeball waterproof receiving portion 120.

The position of the pressure regulating member 130 listed above is not particularly limited, and may be a position where the volume can be changed by the pressure generated inside the eyeball waterproof receiving unit 120.

For example, the pressure regulating member 130 may be attached to face one side of the eyeball waterproof receiving unit 120.

As mentioned above, the pressure regulating member 130 is preferably made of a flexible material that can be changed in volume by an external force, and in this case, the volume of the pressure regulating member 130 may be variable by an external force. It is preferable that a gas is stored.

Figure 7 is a schematic diagram showing an intraocular pressure regulating device according to another embodiment of the present invention.

In some cases, as shown in FIG. 7, the elastic member 160 may be mounted inside the pressure regulating member 130. At this time, the volume of the pressure regulating member 130 is preferably smaller than the volume of the eyeball waterproof receiving portion 120 before being mounted in the storage space of the eyeball waterproof receiving portion 120. Thus, when the volume of the pressure regulating member 130 is changed by the elasticity of the material elasticity of the pressure regulating member 130 itself and the elastic member 160 mounted therein, the pressure regulating member 130 is wrinkled, or the like. It can prevent the wrong deformation of.

In this case, the elastic member 160 may provide an elastic restoring force to the pressure regulating member 130 reduced by the external force. Specifically, after the pressure regulating member 130 is reduced by the pressure of the eye waterproof introduced into the eye waterproof accommodating part 120, the pressure when the eye waterproof leaks from the eye waterproof accommodating part 120 to the outside again. The adjusting member 130 may be restored to its original volume by the elastic restoring force provided from the elastic member 160. Of course, the pressure regulating member 130 may be provided with an elastic restoring force by a gas that may be variable in volume by an external force.

When the volume change of the pressure regulating member 130 is minute and there is almost no movement of the pressure regulating member 130, the amount of eye waterproof discharged to the outside through the first micro through hole 121 is reduced so that the intraocular pressure is increased. Problems may arise. In this case, the elastic member 160 may be mounted inside the pressure regulating member 130 to increase the elastic restoring force of the pressure regulating member 130.

In addition, when the pressure adjusting member 130 is made very thin, an unwanted shape change such as crumpling without volume change of the pressure adjusting member 130 may occur. In this case, too, the elastic member 160 may be mounted inside the pressure regulating member 130 to maintain the shape of the pressure regulating member 130 and change the volume. In this case, forming the volume of the pressure adjusting member 130 to be smaller than the internal volume of the eyeball waterproofing unit 120 before being mounted in the storage space of the eyeball waterproofing unit 120 may also help to prevent erroneous deformation. In this case, the pressure regulating member 130 may be a silicon balloon.

The material constituting the elastic member is not particularly limited and may be, for example, made of a plastic resin that is harmless to a human body. In addition, the elastic member may be a spring made of a polypropylene material used in the drainage device.

In addition, the partition wall corresponding to the shape of the pressure regulating member may be attached to the front end of the elastic member so that the pressure of the housing portion may be effectively transmitted to the elastic member inside the pressure regulating member. This partition may also be made of plastic resin.

Hereinafter, the role of the elastic member 160 will be described in detail by restricting each configuration of the intraocular pressure adjusting device 100 according to the present embodiment.

Consider the case in which the shape of the eyeball-proof receiving portion 120 is formed into a rectangular parallelepiped, its size is set to 10 mm X 5 mm X 15 mm, and a minimum pressure of 8 mm Hg for preventing hypotony. This means the pressure excluding atmospheric pressure, so the pressure is 1atm + 8mmHg = (760 + 8) mmHg when the actual pressure regulating member is mounted in the eye waterproof receiving unit. At this time, the case of adjusting the spring constant of the elastic member, the internal gas pressure of the pressure regulating member will be described in detail.

Example 1)

When the spring constant (k) of the elastic member is 30 N / m, the expected change in the length of one side of the pressure regulating member (15 mm) while the other side is fixed is changed by 1 mm for every 5 mmHg of intraocular pressure (i.e., volume change 1/15). )to be. At this time, if the pressure regulating member gas pressure is set to be 380mmHg = 1 / 2atm, the spring before deformation should be mounted in a compressed state to 15mm, the length of one side of the accommodating part. The pressure regulating member pressure in this state is (760 + 8) mmHg. In this state, when the elastic member spring is reduced by 1mm (ie, the volume is reduced by 1/15, 10mm, 5mm size is fixed), the pressure change inside the pressure regulating member is 5mmHg in the spring part and in the gas part. A total of 30 mmHg increases with a 25 mmHg increase. This means that when the patient's eye pressure is 38mmHg, the pressure regulating member is reduced by 1mm (ie, volume is reduced by 1/15).

Example 2)

When the pressure regulating member gas pressure is lower than in Example 1

When the spring constant (k) of the elastic member is 30 N / m, the expected change in the length of one side of the pressure regulating member (15 mm) while the other side is fixed is 1 mm change (ie volume change 1/15) of 5 mmHg of intraocular pressure. Same as) At this time, if the pressure adjusting member gas pressure is set to be 76mmHg = 1 / 10atm, the spring before deformation should be mounted in a compressed state to 15mm, the length of one side of the accommodating part. The pressure regulating member pressure in this state is (760 + 8) mmHg. In this state, when the elastic member spring is reduced by 1mm (ie, the volume is reduced by 1/15, 10mm, 5mm size is fixed), the pressure change inside the pressure regulating member is 5mmHg in the spring part and in the gas part. 5 mmHg increase results in a total of 10 mmHg. This means that the pressure regulating member 1 mm decreases when the patient's eye pressure is 18 mmHg (that is, volume 1/15 decrease), the pressure regulating member 2 mm when 28 mmHg, and the pressure regulating member 3 mm when 38 mmHg.

Example 3)

When spring constant is smaller than example 1

When the spring constant (k) of the elastic member is 15 N / m, the expected change in the length of one side of the pressure regulating member (15 mm) in the state where the other side is fixed is changed by 2 mm for every 5 mmHg of intraocular pressure (ie, volume change 2/15). )to be. At this time, if the pressure regulating member gas pressure is set to 380mmHg = 1 / 2atm, the spring before deformation should be mounted in a compressed state to 15mm, the length of one side of the accommodating part. The pressure regulating member pressure in this state is (760 + 8) mmHg. In this state, when the elastic member spring is reduced by 1mm (ie, the volume is reduced by 1/15, 10mm, 5mm size is fixed), the pressure change inside the pressure regulating member is 2.5mmHg in the spring part and the gas part. Increasing the 25mmHg to 27.5mmHg. This means that when the patient's eye pressure is 35.5 mmHg, the pressure regulating member is reduced by 1 mm (ie, volume is reduced by 1/15).

Therefore, making the pressure regulating member gas pressure as small as possible can further widen the ocular waterproofing outflow area of the housing. Reducing the spring constant of the elastic member or increasing the area of the front end of the elastic member or the partition wall of the front end also helps increase the ocular waterproof outflow area. In addition, increasing the volume of the ocular waterproof accommodating portion and the corresponding pressure regulating member also contributes to widening the ocular waterproof outflow area.

On the other hand, the outer surface of the pressure regulating member 130 may be coated with a heat insulating material or a heat insulating member.

The volume of the pressure regulating member 130 mounted inside the intraocular pressure regulating device 100 is not greatly changed by the general body temperature change, but the volume of the pressure regulating member 130 is changed by a special body temperature change such as low body temperature or solid temperature. can do. In order to solve this problem, the outer surface of the pressure regulating member 130 according to the present embodiment is coated with a heat insulating material or a heat insulating member is installed, to block the volume change of the pressure regulating member 130 according to the abnormal change in body temperature. Can be.

The method of reducing the volume of the gas inside the pressure regulating member by putting the elastic member in the pressure regulating member 130 may also minimize the volume change of the pressure regulating member due to temperature.

The heat insulating material is not particularly limited as long as it can block the temperature change of the intraocular pressure control device, and may have a structure in which a vacuum layer or an air layer is formed. For example, it may have a structure in which an air layer having a thickness of 5 mm or less is formed. The principle of preventing temperature change by forming a vacuum layer or air layer is published in the previously known article "The Effect of Air Gap of Fire Protective Clothing Material on Thermal Protection Performance, Jun Kyung Lee, Jung Sook Kwon, Journal of Korean Institute of Fire Science and Engineering, 2014" Therefore, it will be omitted herein.

Meanwhile, as shown in FIGS. 1, 2, 3, 6, and 7, a stopper 140 having an elastic restoring force of a predetermined size may be attached to one side of the pressure regulating member 130. At this time, the stopper 140 can be easily penetrated by the syringe, it is preferable that the through-hole is filled with a material to seal again after removal of the syringe. For example, the stopper 140 may be a silicone cap.

After surgically mounting the intraocular pressure control device 100 according to the present embodiment to the target patient, the above-described stopper 140 may be used to adjust the volume or pressure inside the pressure adjusting member 130.

More specifically, after inserting the syringe through the stopper 140, it is possible to increase or decrease the volume of the pressure regulating member 130, in some cases to adjust the amount of gas contained in the pressure regulating member 130 Can be.

Therefore, according to the intraocular pressure regulating device 100 of the present embodiment, a stopper 140 having an elastic restoring force is attached to one side of the pressure regulating member 130, and the pressure inside the pressure regulating member 130 using a syringe.
