  The present invention relates to an eye cleaning device and an eye cleaning device in medicine that can easily and reliably perform eye cleaning.

  When cleaning an eyeball with foreign substances such as organic solvents, hazardous substances, or solid substances entering and adhering at a medical site, make the patient open their eyes and place the cleaning tube that discharges the cleaning liquid in front of the eyeball, and then discharge it from the cleaning tube. The washing solution is continuously poured and dripped onto the surface of the eyeball to wash away foreign substances adhering to the cornea. In addition to such conventional cleaning methods, those described in Patent Documents 1 to 3 are known as eye cleaning devices.

  However, with the conventional cleaning method in which the cleaning tube that discharges the cleaning solution is positioned in front of the eyeball to clean the eyeball, the patient cannot move during cleaning, and the patient's face in an open state shakes even slightly, and the cleaning tube If the position is shifted, the cleaning liquid may come off the eye. Therefore, the cleaning liquid cannot be applied to the eye continuously and stably.

Since the conventional eye cleaning devices described in Patent Documents 1 to 3 are used at home, there is a problem for medical use. In the eye washer described in Patent Document 1, the cleaning liquid receiving cup is applied to the eyes, and the eye is cleaned by spraying the cleaning liquid from the liquid injection hole provided at the bottom of the cleaning liquid receiving cup. It cannot be cleaned unless the open state is forcibly maintained using Further, in the eyewash container described in Patent Document 2 and the eyewash device described in Patent Document 3, since the eyes are washed with the washing liquid stored in the cup-shaped container, the eyes are not always washed with a clean washing liquid. Absent. Accordingly, since the eyes are washed again with the washing liquid that has been washed away by the washed away chemicals and dirt, it is impossible to continuously wash with a clean washing liquid.
In addition, these cleaning devices can achieve a certain degree of eye surface cleaning (cleaning of the corneal portion), but cleaning of the conjunctival portion covered with the eyelid is extremely insufficient. This is because if the cleaning liquid is supplied only to the surface of the eyeball, the cleaning liquid does not sufficiently flow into a narrow portion where the cleaning liquid is difficult to enter, such as the conjunctiva portion. Therefore, it is necessary to remove solid foreign substances and substances that are insoluble in the cleaning liquid, such as slaked lime, or that are extremely low in solubility and difficult to dissolve, by physical force (mechanical) by the cleaning liquid. A means for removing these foreign substances is necessary due to mechanical force), but it is difficult to achieve this sufficiently with conventional devices.

SUMMARY OF THE INVENTION An object of the present invention is to provide an eye cleaning device and an eye cleaning device that can clean an eye reliably by allowing a cleaning liquid to be continuously discharged to the eye, and enables rapid eye cleaning treatment. To do.
It is another object of the present invention to provide an eye cleaning device and an eye cleaning device that can maintain an unfolded state and can reliably supply a cleaning liquid to an eyeball portion to be cleaned.
In addition, the corneal region is narrow as well as the conjunctival region, and it is difficult for the cleaning solution to enter by conventional cleaning methods. As a result, it is possible to efficiently clean and remove foreign matter and chemicals that have entered the site that is difficult to clean and remove foreign matter. It is another object of the present invention to provide an eye cleaning device and a cleaning device that can be used.

The first configuration of the eye cleaning device of the present invention is an eye cleaning device having an eye opening function for opening the eyelid in an open state and an eye cleaning function for introducing a cleaning liquid into the eye to clean the eye at the same time. Specifically, it is an eye cleaning device in which the eye opening function and the eye washing function are integrated.
In this case, the eye opening function is achieved by a pair of supports that bring the upper and lower eyelids into an open state, and the eye washing function is achieved by a cleaning body that discharges a cleaning liquid to the eyes that are in the open state. .
Then, the support body having a hollow structure is provided with a cleaning body having a discharge port, and the support body also serves as the cleaning body, whereby the support body and the cleaning body can be integrated.
According to the first configuration, the upper and lower eyelids are opened from the pair of supports, and in that state, the cleaning liquid is discharged from the discharge port in the cleaning portion of the cleaning body attached to the support to perform cleaning. Even if the patient moves during cleaning, the eye cleaning device installed in the eye does not slip or come off, so that the cleaning liquid can be reliably delivered to the eye. At the same time, since the cleaning liquid is continuously supplied, the cleaning liquid containing the cleaning substance used for cleaning does not stay in the eye that is the cleaning portion, and as a result, sanitary eye cleaning becomes possible. In this case, the support has a hollow structure. By providing the support with a cleaning portion having a discharge port, the support can also be an integrated type that also serves as the cleaning body.

By making the cleaning body a structure in which the direction and position of the discharge port are adjusted, it is possible to provide a cleaning section that can perform corneal cleaning or conjunctival cleaning. Furthermore, the cornea and the conjunctiva can be simultaneously cleaned by adjusting the direction and position of the discharge port to both the cornea side and the conjunctiva side.
In this case, in order to wash the conjunctiva and / or cornea more effectively in the case of an eye cleaning device in which the cleaning body is joined and integrated with the support, and the cleaning portion of the cleaning body is laid on the support portion of the support, It is preferable to make the thickness of the support portion of the support as thin as possible for the purpose of sufficiently achieving permanent opening and preventing the cleaning as much as possible.

In the second configuration of the eye washer according to the present invention, it is possible to provide an eye cleaning device in which each support portion of the pair of supports also serves as a cleaning portion. In the eye cleaning device, the cleaning liquid is discharged from the discharge port provided in the support portion of the support, and the cleaning liquid is continuously discharged from the discharge port by continuously supplying the cleaning liquid. Washing is done.
The pair of supports that are in the open state are connected to the opening adjustment part so that the degree of opening can be adjusted, or the degree of opening is fixed by forming with a substantially elliptical cleaning tube with one end open. Or can be a target.

In this case, the cornea and / or the conjunctiva can be cleaned by adjusting the position and direction of the discharge port of the cleaning section of the support (also serving as a cleaning body).
In other words, the conjunctiva can be mainly cleaned by designing the discharge port of the cleaning section provided in the support (also serving as the cleaning body) to be discharged to the conjunctiva portion. The cornea can be simultaneously cleaned when the cleaning liquid that has entered the eye is discharged from the eye, and the cornea and the conjunctiva can be cleaned simultaneously. Further, the cornea can be mainly cleaned by designing the discharge port of the cleaning unit to be discharged to the cornea portion.

  Furthermore, the conjunctiva and cornea can be cleaned simultaneously by designing the discharge port of the cleaning section to be discharged to both the conjunctival portion and the cornea portion. In the eye cleaning device of the second configuration, if a discharge port is provided so as to clean the conjunctiva and cornea at the same time, the amount of cleaning liquid discharged to the conjunctiva portion (the flow rate or the ratio of the flow rate discharged to the cornea portion) ) By adjusting the area of the outlet of the conjunctiva cleaning part, the area of the outlet of the cornea cleaning part, etc. in consideration of the liquid resistance that occurs during the release to the conjunctiva and the liquid resistance that occurs during the cornea release. The ratio of the discharge amount to the conjunctiva side and the discharge port amount to the cornea side can be adjusted.

  Generally, since the liquid resistance when discharging to the conjunctiva side is larger than the liquid resistance when discharging to the cornea side, the liquid resistance of the conjunctival side discharge port is made smaller than the liquid resistance of the cornea side discharge port. Thus, the flow rate balance of the liquid can be adjusted.

  A third configuration of the cleaning tool of the present invention is the first configuration in which the cleaning section of the cleaning body is joined and attached to the support section of the support body, the support body has a hollow structure, and the cleaning liquid discharge port is provided in the support section. A cleaning unit (conjunctival cleaning unit) is provided. The cleaning liquid discharged from the discharge port of the cleaning section provided in the support section is discharged to the conjunctiva in an open state, and the conjunctiva cleaning is continuously performed by continuously supplying the cleaning liquid. On the other hand, by continuously supplying the cleaning liquid to the cleaning body, the cleaning liquid is discharged to the cornea from the cleaning unit provided with the discharge port, thereby cleaning the cornea.

  As a result, the cleaning liquid is continuously supplied in an open state from the discharge port of the corneal cleaning unit and the discharge port of the conjunctiva cleaning unit, and as a result, the cleaning liquid used for the supply and cleaning of the cleaning solution continuously. The cornea can be continuously washed with a new washing solution at all times. Accordingly, not only the conjunctiva but also the cornea can be efficiently and hygienically cleaned at the same time, and the cornea can be prevented from being contaminated by the cleaning liquid that has washed the conjunctiva.

  According to a fourth configuration of the cleaning tool of the present invention, the discharge port of the corneal cleaning unit is arranged in accordance with a position where the discharge port contacts and holds the edge of the upper lid and the lower lid of the support. To do. When observing or performing surgery on the eye in the open state, if the discharge port of the corneal cleaning unit is located in the center of the eye in the open state, the cleaning liquid can be discharged toward the cornea, It becomes an obstacle when the corneal cleaning unit observes the state of the cornea, the state of the edge of the eyelid and the like. According to the fourth configuration, since the discharge port of the corneal cleaning unit is arranged in accordance with the position held by the support unit of the support, the position of the discharge port is located at the edge of the eyelid, so the entire front surface of the eyeball Do not get in the way of observation.

According to a fifth configuration of the cleaning instrument of the present invention, the conjunctival cleaning unit provided in the support is formed by a cleaning tube extending in the left-right direction of the eye, and a discharge port for discharging the cleaning liquid along the axis is provided in the back. One or more are provided in the lateral direction.
According to the fifth configuration, since the conjunctival cleaning part is formed by the cleaning tube extending in the left-right direction of the eye, the area hitting the spherical surface of the eyeball and the inner side surface of the eyelid is wide, so It is difficult to attach.
The cleaning tool of the present invention may be a cleaning tool in which one to a plurality of configurations of the first to fifth configurations described above are combined.

  The eye cleaning device of the present invention is an eye cleaning device including an eye cleaning device including a conjunctival cleaning unit and / or a cornea cleaning unit, and a liquid feeding unit that supplies a cleaning liquid to the conjunctival cleaning unit. Here, the liquid feeding part is constituted by a storage part, a liquid feeding means for feeding the cleaning liquid to the cleaning instrument, a liquid feeding pipe for feeding the cleaning liquid to the cleaning instrument, and a flow rate adjusting means for adjusting the liquid feeding amount. The

  The storage section referred to in the present invention stores a cleaning liquid to be used for eye cleaning, and specifically, a resinous bag (bag) or resin used when a liquid medicine is poured into a human body by drip or the like. Examples include a pressurized bag, a metal tank, a resin bottle, a glass bottle, and the like, and are not particularly limited as long as the container can store a certain amount of cleaning liquid. However, a material in which the container material is likely to corrode or corrode due to contact between the container and the cleaning liquid, or a material from which the plasticizer in the resin or the like elutes due to contact with the cleaning liquid is not preferable.

  Further, the liquid feeding means referred to in the present invention is a means or power when liquid is fed from the liquid washing section to the washing section via the liquid feeding pipe, and is a means capable of feeding the cleaning liquid in the storage section to the cleaning instrument. Any means can be used as long as it is used. Specifically, the storage unit is installed at a position that is a certain height higher than the position of the eye to be cleaned. Examples include so-called differential pressure due to a pressure difference between the inside of the container and the discharge port, and liquid feeding means by pump power.

  When the potential energy is used as the liquid feeding means, generally, the difference in potential energy (the level of the discharge port of the cleaning unit used for cleaning the target eye and the level of the cleaning liquid stored in the storage unit) This means the difference). The height difference is not particularly limited as long as the eye washing liquid stored in the storage portion is a height difference sufficient to be discharged at a desired flow rate from the discharge port of the cleaning unit of the cleaning instrument, but preferably within 7 m, More preferably, 5 m or less is recommended. Moreover, since a certain level difference is required, 0.3 m or more, preferably 0.5 m or more is recommended. As a matter of course, the liquid level of the cleaning liquid in the reservoir is set higher than the discharge port surface of the cleaning tool. If the potential energy difference (height difference) is too large, the cleaning liquid is suddenly and excessively discharged from the discharge port of the cleaning unit, and the pressure of the discharge target damages the eyes of normal subjects, or the amount of liquid in the storage unit suddenly increases. Decrease, and frequent addition of cleaning solution may be required. Moreover, it becomes difficult to implement when considering the facility (especially the height of the ceiling) that actually performs the cleaning action. If the height difference (potential energy difference) is too small, the cleaning liquid may not be sufficiently discharged from the discharge port due to the resistance of the discharge port or the liquid supply pipe.

  As the liquid feeding means, back pressure can be used in the present invention. Specifically, a pressure greater than atmospheric pressure (usually the cleaning unit discharge port is atmospheric pressure) is applied as a back pressure to a reservoir composed of a sealed container, and the pressure difference between the back pressure and the atmospheric pressure is sent as power. It is means to do. Usually, the pressure difference from the atmospheric pressure is recommended to be 70 kPa or less, preferably 50 kPa or less. If too high back pressure is applied, the cleaning liquid is suddenly discharged from the discharge port of the cleaning section at a high linear velocity, which may damage the cornea, conjunctiva and the like to be cleaned. Further, when a back pressure that is too small from the atmospheric pressure is applied, the cleaning liquid may not be sufficiently discharged from the discharge port due to the resistance of the discharge port or the liquid supply pipe.

  Here, as described above, when the back pressure is applied, it is necessary to apply the back pressure at a constant pressure or variably, and therefore it is necessary to adjust the back pressure. As a means for adjusting the back pressure, for example, when the back pressure is applied by gas supplied from a cylinder, a compressor, or the like, a method of installing a secondary pressure regulating valve in front of the storage portion gas introduction port is generally used. . As another method, a method may be employed in which a purge valve is provided in the storage unit, and the gas introduced to apply the back pressure is maintained at a constant pressure above a certain pressure by purging.

  In the present invention, as a specific example of means for applying back pressure, a gas having a constant pressure is introduced into a container that is a storage part, or the container that is a storage part is formed into a cylinder shape, and the cleaning liquid level in the storage container A method such as applying a certain load to is used. In this case, it is necessary to maintain the sealing property with the sealing material so that the cleaning liquid does not leak from the contact surface between the object to be loaded and the cylinder wall surface. Further, the magnitude of the back pressure applied is determined by the magnitude of the load applied to the liquid surface.

  When pressurized gas is used as means for applying back pressure, air is recommended as the gas to be used. The reason for this is that if all of the stored cleaning solution in the container serving as the storage unit is used up and emptied, the gas used for back pressure is transferred from the storage unit container to the eye cleaning unit through the piping. It is discharged from a certain outlet. At that time, if the gas is not air but an inert gas such as nitrogen or argon or a gas not containing oxygen, the gas may be released to the face of the subject who is trying to wash the eyes, and the patient may feel stuffy.

  Further, when the back pressure by the pressurized gas is used as the liquid feeding means, as described above, when the cleaning liquid stored in the reservoir is exhausted, the pressurized gas used for the back pressure is directly In order to prevent this, there is a risk of discharge from the discharge port of the cleaning unit, which may adversely affect the eye to be cleaned and the human body to be cleaned. It is also recommended from the viewpoint of safety to provide a liquid level sensor that senses the liquid level and to provide an alarm and / or liquid supply shut-off function (alarm and / or shutdown sequence) when the liquid level drops to a certain level. The These sequences may be applied to the liquid feeding section powered by the above potential energy.

  Similarly, in the present invention, it is also recommended to use a pump as the liquid feeding means. The pump as the liquid feeding means is installed between the storage part and the cleaning tool of the present invention. The reservoir and the pump, and the pump and the eye cleaning device are connected by a liquid feeding pipe.

  As the pump used in the present invention, any pump can be used as long as it can transport the liquid at a flow rate within a predetermined range. Specific examples of pumps that are easy to implement include plunger type pumps and tube pumps generally referred to as peristaltic pumps.

  In the apparatus of the present invention, it is also recommended to attach a flow rate adjusting means to the liquid feeding part. By attaching a flow rate adjusting means, it becomes possible to adjust the amount of cleaning liquid according to the degree of chemical damage to the eye to be cleaned and the degree of impurity contamination, etc. It can be achieved accordingly.

  In particular, in a cleaning apparatus comprising a plurality of independent cleaning units as described later, each target site (for example, the upper and lower parts of the eye, the upper and lower conjunctival parts, the conjunctival and corneal parts), respectively. Independently, a desired cleaning solution is fed and more efficient eye cleaning is possible.

  The flow rate adjusting means in the present invention adjusts and controls the liquid flow rate of the cleaning liquid fed by the storage unit and the liquid feeding unit and discharged from the discharge port of each cleaning unit, and the liquid flow rate can be adjusted. Any device can be used as long as it is a device. Specifically, for example, when liquid is fed by position potential energy or power by back pressure, the flow rate adjusting needle valve (the opening degree of the valve) is used. The flow rate can be adjusted by using a soft cock such as a silicone tube as a liquid feed tube. The flow rate can also be adjusted by adjusting the opening of the tube.

Further, as the liquid feeding means, when the power of the liquid feeding is a position (potential energy difference), the flow rate can be adjusted also by the potential energy difference. Specifically, in order to increase the flow rate, the liquid flow rate can be increased by increasing the liquid level in the reservoir and increasing the height difference from the discharge port portion of the cleaning unit. Naturally, the liquid flow rate can be lowered by reducing the height difference. Similarly, when the power of liquid feeding as the liquid feeding means applies back pressure to the cleaning liquid in the reservoir, the flow rate is increased by increasing the back pressure, and the flow rate is decreased by decreasing the back pressure. be able to.
Similarly, when the back pressure is used as power, the flow rate can be adjusted by adjusting the back pressure. Furthermore, it is preferable to keep the back pressure constant in order to adjust the flow rate stably when adjusting the amount of liquid fed by a needle valve or a mass flow control valve as a back pressure and flow rate adjusting means.

Further, when a plunger type pump or a tube pump is used as the liquid feeding unit, the pump itself has a flow rate adjusting function, and can serve as both the liquid feeding unit and the flow rate adjusting unit.
Regarding the flow rate adjustment, a plurality of these flow rate adjusting means can be combined.
However, for example, when a plunger pump is used for both the liquid feeding power and the flow rate adjustment, the cleaning liquid storage section is stored in the cleaning liquid storage section with respect to the cleaning section discharge port due to a back pressure or a positional energy difference. It should be noted that when the pressure becomes high, the flow rate adjustment function of the pump does not work due to the structure of the plunger pump, and only the flow rate adjustment function by the pressure difference (potential energy difference or back pressure difference) is achieved. It is.
For the flow rate adjusting means, it is also recommended that a flow meter (flow meter) be installed between the flow rate adjusting means and the eye washer in order to confirm the actual liquid flow rate. Thereby, the actual flow rate can be directly confirmed.

  As the flow meter, any flow meter can be used as long as the actual flow rate is indicated. Specifically, a float type flow meter, a digital flow meter that senses and indicates mass flow, etc. Is exemplified. In particular, a flow rate regulator such as a mass flow control valve may be provided with an indicator indicating the flow rate.

  In the present invention, the liquid feeding section composed of the storage section, the liquid feeding means, and the flow rate adjusting means and the cleaning instrument are connected by a liquid feeding pipe. Furthermore, the storage section, the liquid feeding means, and the flow rate adjusting means that are respectively installed are also connected by a liquid feeding pipe. The cleaning liquid is supplied to the cleaning instrument through these liquid supply pipes, and eye cleaning is performed.

  As the liquid feeding pipe used in the present invention, any material pipe can be used as long as the liquid can be transported. However, it should be avoided to use a material corroded by the cleaning liquid and a material from which harmful substances are eluted by the cleaning liquid. It is. Specifically, materials such as silicone, Teflon (registered trademark), stainless steel, Viton (registered trademark: fluorine-based rubber) are recommended.

  In addition, the flow control means (including the flow meter if a flow meter is installed) from the storage part may be connected by a hard fixed pipe that does not cause deformation such as hard bending or deflection. About the downstream liquid supply pipe | tube to subsequent washing | cleaning instruments, it is preferable that a liquid supply pipe | tube is a flexible tube which bends easily or bends. The reason for this is that when the liquid feeding part and the cleaning instrument are connected, when the eye cleaning instrument of the present invention is attached to the eye wash subject and the pipe (liquid feeding pipe) from the flow rate adjusting means is connected, the pipe This is because, if the pipe is not flexible, the cleaning instrument is tensioned due to movement of the eye cleaning subject and the attached cleaning instrument may come off the eye.

  From this point of view, a silicone tube, a Teflon flexible tube, a Viton tube or the like is recommended as a flexible tube in consideration of the above-described material aspects. A stainless steel flexible tube can also be used.

The eye cleaning device of the present invention is a device capable of supplying a cleaning solution to each cleaning unit of a cleaning instrument by a single liquid supply unit, and further, an independent liquid supply system by a plurality of liquid supply units. Accordingly, an eye cleaning apparatus that corresponds to a plurality of cleaning units and supplies a cleaning liquid is also an eye cleaning apparatus in the present invention.
For example, in an eye cleaning device using a single liquid supply, liquid supply to a cleaning instrument composed of a pair of cleaning bodies is performed by passing the cleaning liquid flowing through the flow rate adjusting means (a flow meter if a flow meter is installed). In order to supply the cleaning tool, the flexible tube can be supplied by branching into two.
Similarly, when supplying the cleaning liquid to the conjunctiva cleaning unit that also serves as a pair of supports and the corneal cleaning unit of the cleaning body installed along the pair of supports, the branching is performed by the number of receiving ports of each corneal cleaning unit. Then, connect with a flexible tube or the like to supply the cleaning solution.

Here, when the cleaning liquid is sent to a plurality of cleaning parts by a single liquid feeding part, the cleaning liquid is evenly distributed to each cleaning part due to resistance due to the position installed in each cleaning part, resistance due to gravity, etc. It may be difficult to supply.
In such a case, for example, it is recommended that the corneal cleaning part and the conjunctival cleaning part be independently supplied with the cleaning liquid by the independent liquid supply part. The reason for this is that when the cleaning liquid is supplied by a single liquid feeding part due to the form of the individual discharge ports of the corneal cleaning part and the conjunctival cleaning part, the difference in resistance between the conjunctival part and the corneal part, etc. This is because the discharge amount of the cleaning liquid from the discharge port is extremely reduced, the cleaning effect of the cleaning liquid becomes unbalanced, and the cleaning effect of the conjunctiva portion may be reduced.

Specifically, the discharge port of the corneal cleaning unit almost receives only resistance of the piping resistance, but the discharge port on the conjunctival cleaning unit side is in contact with a narrow conjunctival portion in addition to these resistances. In addition, the resistance of the conjunctiva part is also received, and if the cross-sectional area of the discharge port in the conjunctival cleaning part is smaller than the cross-sectional area of the discharge port of the corneal cleaning part, the resistance increases further, and most cleaning liquids Supplied to the corneal cleaning section and resistance increases.
In such a case, the independent liquid feeding unit supplies the cleaning liquid set at a constant flow rate from the first liquid feeding unit to the pair of upper and lower corneal cleaning units, respectively, and the second is supplied to the pair of upper and lower conjunctival cleaning units. The above-mentioned problems can be solved by supplying the cleaning liquid set at a constant flow rate from the liquid supply section, and the desired amount of cleaning liquid is supplied to each cleaning section to efficiently clean the eyes. Is done.

  Moreover, even if it is achieved that the cleaning liquid is supplied to each cleaning unit in a well-balanced manner with a single liquid delivery system, depending on, for example, the contamination status of each part of the eye, In some cases, it is preferable to supply the cleaning liquid by changing the flow rate of the cleaning liquid to each cleaning unit as required, such as supplying a large amount of cleaning liquid.

  Furthermore, in the eye cleaning apparatus of the present invention, when the eye cleaning instrument is configured by a pair of upper and lower supports (including a support having a cleaning unit) and a cleaning body, each cleaning body and the other The difference in resistance that the cleaning body receives due to the difference in structure and potential energy of the eye may affect the flow rate of the cleaning liquid. For the same reason, there may be a difference in resistance between the support having one cleaning section and the other support.

  In such a case, the other cleaning body (specifically, the pair of cleaning bodies) (specifically, the pair of cleaning bodies, specifically, the upper cleaning body among the pair of cleaning bodies) is separately supplied to the other cleaning body (specifically, the pair of cleaning bodies). The cleaning liquid can be supplied to the cleaning units of the respective cleaning units by the second liquid feeding unit. In this case, even when the eye cleaning device has a pair of cleaning parts in the support part, and when the pair of supports also serve as the pair of cleaning bodies, each of the one cleaning part similarly has an independent liquid feeding part. The cleaning liquid can be individually supplied to the cleaning section of the support.

Specifically, each of the corneal cleaning bodies and each of the corneal cleaning bodies and the liquid feeding sections to a cleaning instrument comprising a support having a pair of corneal cleaning bodies and a pair of conjunctival cleaning sections is individually provided by the first to fourth liquid feeding sections. Supplying a cleaning solution to the conjunctival cleaning unit is also one of the eye cleaning devices of the present invention.
In addition, the corneal cleaning part that does not receive a large resistance other than the tube resistance is relatively less susceptible to the resistance than the tube resistance by the first liquid feeding unit. The eye cleaning device that supplies the cleaning liquid to the cleaning portion of one support body by the second liquid feeding portion and the cleaning portion of the other support body by the third liquid feeding portion is also the cleaning device referred to in the present invention. One.

  Here, the independent liquid feeding section referred to in the present invention is a liquid feeding section including a cleaning liquid storage section, a positional energy difference, a liquid feeding means such as a back pressure and a pump, and a flow rate adjusting means constituting the liquid feeding section. Although it also means that each is an independent liquid feeding part, it does not mean only such a liquid feeding part configuration, and the liquid feeding means and the storage part are not necessarily independent, and all liquid feeding parts Even if one reservoir also serves as one reservoir or a plurality of liquid feeding systems for the system, the flow control means (including the flow meter if a flow meter is installed) and the piping after that are individually It also means independent.

  The reason for this is that, in view of the above description, an independent cleaning liquid supply system can be constructed as described above by supplying a cleaning liquid whose flow rate is independently adjusted to each part of the eye cleaning device. It is.

As the cleaning liquid used in the present invention, any liquid can be used as long as it is not harmful to human tissues and organs including eyes and can wash away contaminants. The washing liquid is generally exemplified by physiological saline, aseptic pure water, tap water, etc., but for example, Opgard (registered trademark) manufactured by Senju Pharmaceutical Co., Ltd., which is a buffer solution in which an inorganic salt or the like is added to sterile water. And oxyglutathione eye perfusion / cleaning solution manufactured by Alcon.
In addition, the amount of cleaning solution (supply rate) used for cleaning in the eye cleaning of the present invention is recommended to be 250 mL to 5 L of cleaning solution per hour, preferably 500 mL to 2.5 L of cleaning solution, depending on the state of drug contamination in the eye. Is recommended. Of course, it is recommended to adjust the flow rate (supply speed) appropriately without depending on the amount of the cleaning solution, depending on the amount and degree of contamination of the drug or foreign matter.

  In the present invention, since the cleaning unit supplies a sufficient amount of cleaning water to the eye that is opened by the support unit, sanitary cleaning water can be continuously discharged to the eye. Therefore, according to the present invention, the eyes can be reliably washed, and a rapid eye wash treatment can be performed.
