1. 1 . An intraocular fluid drainage device for controlling an intraocular fluid pressure depending on an intraocular pressure in an eye of a patient, comprising: a first part comprising a first tube having a first tube lumen, a second part comprising a second tube having a second tube lumen, and a third part comprising a third tube having a third tube lumen; wherein said first part further comprises an indicator-valve-seal, an indicator window, and a first spring; said first tube is connected in the eye of the patient at a first distal end and to said second part at a first proximal end; said first tube having a first surface opening; said first surface opening is configured to receive the indicator-valve-seal; said indicator-valve-seal is a first moveable blunt structure comprising an indicator scale, wherein said indicator scale comprises colors and numbers; said indicator scale is configured to be seen through said indicator window; said indicator-valve-seal having a direct first fluid contacting side with an intraocular fluid inside said first tube having a first fluid pressure force reflecting the intraocular pressure; said first spring generating a first spring force at said opposing side of the indicator-valve-seal; said first spring having a first adjustable piece configured to adjust said first spring force needed to squeeze or release said first spring; wherein a displacement of said indicator-valve-seal is determined by the difference between said first fluid pressure force and said first spring force; wherein if said first fluid pressure force is less than said first spring force, said indicator-valve-seal would be displaced towards said first tube lumen therefore sealing said first tube and preventing fluid flow and drainage; wherein if said first fluid pressure force is more than the first spring force; the indicator-valve-seal would be displaced away from said first tube lumen therefore opening the first tube, allowing flow and drainage of said intraocular fluid, and decreasing said intraocular pressure; wherein the size of said first tube lumen is proportional to said first fluid pressure force, therefore increasing fluid pressure increases the size of the opening and increases fluid flow and drainage; wherein said colors and numbers shown through said indicator window indicates said displacement of the indicator-valve-seal, therefore indicates intraocular fluid pressure; wherein said second part further comprises a sliding-seal, a valve-cover, and a second spring; said second tube is connected to the first part at a second distal end and to said third part at a second proximal end; said second tube having a tube-surface-opening; said second tube is configured to receive the sliding-seal; said sliding-seal is a second movable blunt structure configured to blunt-seal said second tube and said third tube from inside the second tube lumen and the third tube lumen, respectively; said tube-surface-opening is configured to be sealed by said valve-cover; said valve-cover is movable and having a direct second fluid contacting side with the intraocular fluid inside said second tube having a second fluid pressure force reflecting said intraocular pressure; said second spring generating an a second spring force at said opposing side of the valve-cover; said second spring having a second adjustable piece configured to adjust said second spring force needed to squeeze or release said second spring; said second fluid pressure force dependent on a size of area of said valve-cover exposed to said intraocular fluid; said size of area of said valve-cover exposed to said intraocular fluid is determined by moving said sliding-seal; wherein said position of said valve-cover is determined by the difference between the second fluid pressure force and the second spring force; wherein if the second fluid pressure force is less than the second spring force, the valve-cover would be in a closed position, wherein the valve-cover is displaced towards said tube-surface-opening therefore sealing said second tube and preventing fluid drainage; wherein if said second fluid pressure force is more than said second spring force, said valve-cover would be displaced away from said tube-surface-opening therefore opening said second tube and allowing drainage of intraocular fluid and decreasing said intraocular pressure; wherein said third tube is connected to the second part at a third distal end; said third tube having surface openings; said sliding-seal is configured to blunt-seal said surface openings from inside the third tube lumen; wherein moving the sliding-seal controls the sealing of a number and portion of surface openings therefore controlling said intraocular pressure.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not Applicable NAME OF THE INVENTOR Rakan Alhourani STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR OR A JOINT INVENTOR Not Applicable FIELD OF THE INVENTION The present invention generally relates to a device that drains aqueous humor from inside the eye in order to adjust intraocular pressure (IOP). In this device, the drainage flow rate and amount are adjustable and the IOP can be checked by the patient at any time. BACKGROUND OF THE INVENTION Rakan glaucoma device has an application in managing glaucoma and checking the IOP directly by patient. This device can drain excessive intraocular fluid hence regulating and adjusting the IOP, as the drainage flow rate is self-adjusted depending on IOP and can be readjusted anytime. Also the existence of valve prevents back flow of aqueous humor and it prevents unwanted decrease in IOP (hypotony). SUMMARY OF THE INVENTION The present invention is a drainage device that manages glaucoma using adjustable valves and shunts that precisely control aqueous humor outflow hence IOP. Also, this new device allows patients to self-check IOP.
