Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a glaucoma valve and a glaucoma drainage device. Background Art

[0002] Glaucoma is a blinding eye disease caused primarily by increased intraocular pressure, which damages the optic nerve. Treatment options include medication, laser therapy, and surgery. After glaucoma filtration surgery, a drainage channel, usually a thin tube, is needed to connect the inside and outside of the eye.

[0003] Glaucoma drainage surgery is one of the measures to treat glaucoma. Existing surgeries often use a silicon tube to be implanted in the eye, and a drainage plate is sutured to the sclera. Intraocular fluid collects in the drainage plate under the conjunctiva and is absorbed by the surrounding tissues.

[0004] After glaucoma drainage surgery, the amount of fluid drained from the drainage tube needs to be adjusted according to the patient's recovery time. In the early postoperative period, excessive drainage can easily lead to a shallow anterior chamber. In the middle and late postoperative period, insufficient drainage can easily cause scarring. Existing devices may not be able to absorb excessive intraocular fluid in a short period of time, which can easily lead to a low intraocular pressure-lowering effect.

[0005] To solve the above problems, the present application proposes a glaucoma valve and a glaucoma drainage device. Utility Model Content

[0006] In response to the problems in the related art, the present invention proposes a glaucoma valve and a glaucoma drainage device to overcome the above technical problems existing in the existing related art.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A glaucoma valve comprises a floppy disk, wherein a drainage tube is fixedly inserted into the inner cavity of the floppy disk, a limiting disc is installed on the outer surface of the drainage tube, an adjusting recess is fixedly connected to the outer surface of the limiting disc, a first threaded rod is threadedly connected to the inner cavity of the adjusting recess, a round handle is fixedly connected to the side of the first threaded rod away from the drainage tube, an adjusting plate is rotatably connected to the side of the first threaded rod close to the drainage tube, and the side of the adjusting plate close to the drainage tube is movably connected to the outer surface of the drainage tube.

[0009] A glaucoma drainage device comprises the above-mentioned glaucoma valve, wherein a storage box is movably sleeved on the outer surface of the drainage tube, and the outer surface of the storage box is provided with scale lines.

[0010] The outer surface of the drainage tube is fixedly connected to a positioning block, and the top of the storage box is hinged with a positioning bracket. The outer surface of the positioning bracket is movably connected to the inner surface of the positioning block. By setting the positioning block and the positioning bracket, the positioning bracket can be flipped upward under force, and the storage box can be inserted into the positioning block through the positioning bracket to be fixed to the drainage tube, which is convenient for the operator to quickly remove and separate the drainage tube and the storage box, and conveniently and quickly disinfect and clean the inner surface of the drainage tube.

[0011] Both sides of the storage box are hinged with a shielding plate, and both sides of the storage box are provided with a first storage groove. The inner surface of the storage box is rotatably connected to a handle, and the outer surface of the handle is fixedly connected to a plurality of anti-slip protrusions. By arranging the shielding plate, the first storage groove, the handle and the anti-slip protrusions, after the shielding plate is flipped upward, the operator can control the overall movement of the storage box by holding the handle and the anti-slip protrusions, and the rotatable handle makes it easy for the operator to control the storage box from different angles.

[0012] A second storage slot is provided on the outer surface of the storage box, and a magnetic block is installed on the inner surface of the storage box. The magnetic block is located in the second storage slot. By setting the second storage slot and the magnetic block, when the shielding plate is not disturbed by external force and is vertically downward, the metal shielding plate is tightly adsorbed on the surface of the magnetic block under the action of magnetic force, thereby minimizing the shielding plate from shaking easily and exposing the hidden handle.

[0013] A support block is detachably mounted on one side of the storage box away from the scale line, and a silicone suction cup is mounted on the outer surface of the support block. By arranging the support block and the silicone suction cup, when the silicone suction cup is in close contact with the patient's skin and pressed hard, the silicone suction cup can form a certain negative pressure, thereby adsorbing on the patient's skin, so as to maximize the stability of the storage box and the drainage tube during drainage, and minimize the possibility that the drainage tube shakes randomly during drainage, causing rupture of the patient's wound.

[0014] A second threaded rod is welded to one side of the support block close to the storage box, and the second threaded rod is threadedly connected to the inner cavity of the storage box. By setting the second threaded rod, the operator can drive the second threaded rod to rotate in the same direction by rotating the support block. The second threaded rod can be quickly detached from the interior of the storage box under force rotation, which makes it convenient for the operator to quickly dismantle the vehicle and replace the silicone suction cup and the second threaded rod.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] 1. The glaucoma valve can drive the first threaded rod to rotate in the same direction by rotating the round handle, and the rotation of the first threaded rod can drive the adjustment plate to move vertically in the horizontal direction. The adjustment plate is forced to move to squeeze the drainage tube. The squeezing of the drainage tube can reduce the flow of the internal liquid, making it easier for the operator to control the drainage volume of the drainage tube, minimize the patient's intraocular pressure, and help assist the patient's recovery.

[0017] 2. The glaucoma drainage device can collect excess intraocular fluid discharged by the patient through the drainage tube and storage box, and the operator can observe the collection of intraocular fluid inside the storage box through the scale line. The operator moves the storage box upward until the positioning bracket is completely separated from the positioning block, and the storage box and drainage tube can be quickly separated from each other, which helps the operator to quickly replace the storage box and disinfect and clean the inner surface of the drainage tube.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-2A glaucoma valve includes a soft disk 1, which can be fixed to the skin surface around the patient's eyes using medical tape. A drainage tube 2 is fixedly inserted into the inner cavity of the soft disk 1. The drainage tube 2 needs to be inserted into the patient's eyes to guide the intraocular fluid and minimize the patient's intraocular pressure. The outer surface of the drainage tube 2 is installed with a limiting disc 3, and the outer surface of the limiting disc 3 is fixedly connected with an adjusting recessed block 4, and the inner cavity of the adjusting recessed block 4 is threadedly connected with a first threaded rod 5, and the side of the first threaded rod 5 away from the drainage tube 2 is fixedly connected with a round handle 6, the radius of the round handle 6 is larger than the radius of the first threaded rod 5, and the rotation of the round handle 6 can drive the first threaded rod 5 to rotate; the side of the first threaded rod 5 close to the drainage tube 2 is rotatably connected with an adjusting plate 7, and the side of the adjusting plate 7 close to the drainage tube 2 is movably connected to the outer surface of the drainage tube 2, and the rotation of the first threaded rod 5 can drive the adjusting plate 7 to move along a vertical straight line in the horizontal plane, and the adjusting plate 7 can gradually contact the surface of the drainage tube 2 under force. When the drainage tube 2 is gradually squeezed by the adjusting plate 7, the flow rate of the liquid inside the drainage tube 2 gradually decreases, which is convenient for the operator to quickly control the drainage amount of the drainage tube 2, so as to meet the recovery requirements of the patient at different times after surgery.

[0026] Reference Figure 1-3 A glaucoma drainage device includes the above-mentioned glaucoma valve, a storage box 8 is movably sleeved on the outer surface of the drainage tube 2, and a scale line 9 is provided on the outer surface of the storage box 8. Excess intraocular fluid produced by the patient's eyes can be transported to the inside of the storage box 8 through the drainage tube 2, and the storage box 8 can temporarily store the intraocular fluid to try to avoid excessive secretion of intraocular fluid by the patient, which may lead to the inability of the surrounding tissues under the conjunctiva to be quickly absorbed; and the operator can calculate the collected volume of the intraocular fluid inside the storage box 8 through the scale line 9.

[0027] Reference Figure 1 The outer surface of the drainage tube 2 is fixedly connected to a positioning block 10, and the top of the storage box 8 is hinged with a positioning bracket 11. The outer surface of the positioning bracket 11 is movably connected to the inner surface of the positioning block 10. The storage box 8 is relatively fixed to the drainage tube 2 through the positioning bracket 11 and the positioning block 10. When the storage box 8 is forced to move upward and drives the positioning bracket 11 to completely disengage from the positioning block 10, the storage box 8 contacts the fixed state of the drainage tube 2, and then the storage box 8 moves downward again to quickly detach from the drainage tube 2.

[0028] Reference Figure 1 and Figure 3 , both sides of the storage box 8 are hinged with a shielding plate 12, and both sides of the storage box 8 are provided with a first storage groove 13, and the shielding plate 12 can cover the first storage groove 13 when it hangs naturally; the inner surface of the storage box 8 is rotatably connected to a handle 14, and the outer surface of the handle 14 is fixedly connected to a plurality of anti-slip protrusions 15. The operator can control the movement of the storage box 8 by holding the handle 14, and the anti-slip protrusions 15 on the surface of the handle 14 can increase the friction of the handle 14. At the same time, the rotatable handle 14 is convenient for the operator to control the storage box 8 from multiple angles.

[0029] Reference Figure 3 A second receiving groove 16 is provided on the outer surface of the storage box 8, and a magnetic block 17 is installed on the inner surface of the storage box 8. The magnetic block 17 is located in the second receiving groove 16, and the vertical cross-sectional area of ​​the magnetic block 17 is smaller than the vertical cross-sectional area of ​​the second receiving groove 16; the inner surface of the shielding plate 12, when the shielding plate 12 naturally droops without being disturbed by external force, because the shielding plate 12 is made of metal, the shielding plate 12 remains fixed to the outer surface of the storage box 8 under the action of the magnetic block 17, and the storage box 8 is prevented from being easily loosened by external force and the hidden handle 14 is exposed.

[0030] Reference Figure 3-4 The storage box 8 is detachably mounted with a support block 18 on the side away from the scale line 9. A silicone suction cup 19 is mounted on the outer surface of the support block 18. When the silicone suction cup 19 is in close contact with the patient's skin and pressed hard, the silicone suction cup 19 can form a certain negative pressure, and the storage box 8 can be temporarily adsorbed on the patient's skin surface through the silicone suction cup 19, which is convenient for improving the stability of the drainage tube 2 and the storage box 8 during operation; the operator then sticks the storage box 8 to the patient's skin using medical tape. A second threaded rod 20 is welded to the side of the support block 18 close to the storage box 8. The second threaded rod 20 is threadedly connected to the inner cavity of the storage box 8. The second threaded rod 20 can be rotated under force and gradually move in the direction away from the storage box 8, which is convenient for the operator to quickly remove the support block 18 and the silicone suction cup 19, and to replace the damaged silicone suction cup 19 in time.

[0031] Working principle: First, medical personnel need to insert the drainage tube 2 into the patient's eyes through surgery, and use medical tape to fix the floppy disk 1 and storage box 8 on the patient's skin surface. The drainage tube 2 and storage box 8 can then collect excess intraocular fluid discharged by the patient to reduce the patient's intraocular pressure. In response to the patient's recovery requirements at different stages after surgery, the operator can rotate the first threaded rod 5 to drive the adjustment plate 7 to move. As the contact area between the adjustment plate 7 and the drainage tube 2 increases, the drainage volume of the drainage tube 2 gradually decreases, which is convenient for meeting the patient's early postoperative requirements and avoiding shallow anterior bleeding as much as possible. At the same time, rotating the first threaded rod 5 in the opposite direction can increase the drainage volume of the drainage tube 2, which is convenient for meeting the patient's late postoperative requirements and avoiding scarring as much as possible.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
