[0002] Eyewash devices play a vital role in the treatment of ophthalmic diseases, the management of accidental eye injuries, and the pre- and post-operative care of some eye surgeries. They effectively clean the eyes, removing foreign objects, secretions, residual medications, etc., helping to maintain eye hygiene, promoting eye recovery, and relieving eye discomfort.

[0003] According to a search, Chinese patent document, publication number CN213048138U, discloses a portable eyewash station for ophthalmic care. By incorporating an anti-deposition device, it effectively prevents the eyewash solution inside the container from depositing. Furthermore, this anti-deposition device prevents the eyewash solution from depositing inside the container without affecting the normal placement and use of the portable eyewash station.

[0004] However, in actual use, the above-mentioned device is inconvenient because the nozzle is set to clean the eyes directly, and the medicine will spill onto the ground during the cleaning process. There is no structure to catch the medicine, so it is inconvenient to use. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 An ophthalmic eyewash device with splash protection includes a housing 1. The housing 1 has a cleaning fluid area 2 and a waste fluid area 3 inside, separated by a partition 4. A straight pipe 5 is fixedly connected to the top surface of the housing 1, and a rinsing basin 6 is fixedly connected to the top of the straight pipe 5. A pressurizing component 7 is connected to the inner wall of the cleaning fluid area 2, and an outlet pipe 8 is provided inside the cleaning fluid area 2. One end of the outlet pipe 8 is connected to an outlet valve 9, and one end of the outlet valve 9 is connected to an elbow pipe 10. A horn pipe 11 is fixedly connected to the outer wall of the elbow pipe 10, and a nozzle 12 is threadedly connected to one end of the horn pipe 11. A pressure gauge 13 is installed on the top of the cleaning fluid area 2.

[0025] The booster assembly 7 includes a cylinder 71, a piston 72 is disposed inside the cylinder 71, a pull rod 73 is connected to the end face of the piston 72, a handle 74 is fixedly connected to the top of the pull rod 73, an outlet check valve 75 is fixedly connected to the bottom of the cylinder 71, and an inlet check valve 76 is connected to the bottom of the cylinder 71. One end of the inlet check valve 76 is connected to an intake pipe 77, and an end cap 78 is threadedly connected to the top of the cylinder 71.

[0026] Specifically, the top of the cylinder 71 is fixedly connected to the top of the inner wall of the cleaning fluid zone 2, the top surface of the end cap 78 has a through hole, the pull rod 73 is inserted into the through hole, the top of the box 1 has an air hole, and the end of the suction pipe 77 away from the air inlet one-way valve 76 is connected to the air hole at the top of the box 1.

[0027] The advantage is that by repeatedly pressing the handle 74, the lever 73 is driven, which in turn drives the piston 72 to move up and down. During the downward movement of the piston 72, the gas in the cylinder 71 can be discharged into the cleaning fluid zone 2 inside the box 1 through the exhaust one-way valve 75. During the upward movement of the piston 72, the outside air is drawn back into the cylinder 71 through the intake one-way valve 76 and the suction pipe 77. In this cyclical movement of the piston 72, the pressure value in the cleaning fluid zone 2 can be increased, so that the cleaning solution stored in the cleaning fluid zone 2 can be automatically discharged when cleaning the eyes. The pressure value inside the cleaning fluid zone 2 can be known by observing the pressure gauge 13, thereby avoiding excessive pressure.

[0028] Specifically, the elbow pipe 10 is inserted inside the straight pipe 5, and there is a gap between the outer wall of the elbow pipe 10 and the inner wall of the straight pipe 5. The partition plate 4 is fixedly connected to the inner wall of the box 1. A sealing cover 14 is installed on the top of the cleaning liquid area 2, and a drain valve is connected to the back of the waste liquid area 3. A connecting plate 15 is fixedly connected to the outer surface of the nozzle 12. A connecting plate 2 16 is hinged to one end of the connecting plate 15, and a dust cover 17 is fixedly connected to one end of the connecting plate 2 16.

[0029] The advantages are that cleaning fluid can be injected into the cleaning fluid zone 2 by opening the sealing cover 14. When sufficient pressure is injected into the cleaning fluid zone 2, the outlet valve 9 is turned to connect the elbow pipe 10 and the outlet pipe 8. In this way, the solution in the cleaning fluid zone 2 will automatically enter the outlet pipe 8 under pressure, and then enter the elbow pipe 10 and the two horn pipes 11. Then it will be sprayed out from the two nozzles 12. When the person stands next to the box 1, bends over and puts his / her eyes close to the two nozzles 12, the cleaning fluid sprayed from the nozzles 12 can rinse the eyes. The rinsed cleaning fluid will fall into the rinsing basin 6, and then fall into the waste liquid zone 3 through the straight pipe 5. This can prevent the rinsing fluid from spilling on the ground. By setting a dust cover 17, the nozzles 12 can be covered when not in use, thus preventing dust from entering the nozzles 12. The waste liquid temporarily stored in the waste liquid zone 3 can be automatically discharged by opening the drain valve on the back of the waste liquid zone 3.

[0030] In use, first, open the sealing cap 14 and inject cleaning fluid into the cleaning fluid zone 2. Press the handle 74 repeatedly. The handle 74 drives the lever 73, which in turn drives the piston 72 to move up and down. When the piston 72 moves downward, it discharges the gas in the cylinder 71 into the cleaning fluid zone 2 through the exhaust check valve 75. When it moves upward, it draws outside air into the cylinder 71 through the intake check valve 76 and the suction pipe 77. This cycle continues to increase the pressure in the cleaning fluid zone 2. At the same time, observe the pressure gauge 13 to monitor the pressure and avoid excessive pressure. When the pressure inside the cleaning fluid zone 2 is sufficient, turn the outlet valve 9 to connect it to the outlet. Through the elbow pipe 10 and the outlet pipe 8, the solution in the cleaning fluid zone 2 enters the outlet pipe 8, elbow pipe 10, and horn pipe 11 in sequence under pressure, and finally sprays out from the nozzle 12. Personnel stand next to the box 1, bend over and bring their eyes close to the two nozzles 12 respectively, and let the cleaning fluid sprayed from the nozzles 12 rinse their eyes. The rinsed cleaning fluid falls into the rinsing basin 6, and then falls into the waste liquid zone 3 through the straight pipe 5. When not in use, the nozzles 12 are covered with dust cover 17 to prevent dust from entering. When it is necessary to discharge waste liquid, the drain valve on the back of the waste liquid zone 3 is opened to automatically discharge the waste liquid temporarily stored in the waste liquid zone 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
