Description

Technical Field

[0001] This utility model relates to the technical field of medical supplies, specifically a conjunctival sac irrigation device. Background Technology

[0002] The conjunctival sac is a potential sac-like space surrounded by the palpebral conjunctiva, bulbar conjunctiva, and fornix conjunctiva. As an important protective structure of the eyeball, it prevents foreign objects and bacteria from entering the eye. Through tear secretion, it plays a role in moisturizing and lubricating the eyeball. It can also sense stimuli and make defensive responses with the help of rich blood vessels and nerves. It is closely related to eye health. Many eye diseases such as conjunctivitis and conjunctival concretions occur in this area. At the same time, it is also a key site in ophthalmic treatments such as subconjunctival injections and conjunctival flap covering. The conjunctival sac cleaning device is a device used to clean the conjunctival sac.

[0003] Most existing conjunctival sac cleaning devices use an adjustable micro-pump to drive the cleaning solution in the bottle for cleaning. When rinsing and cleaning the patient's eyes, it is often necessary to make fine adjustments according to the condition of the patient's conjunctival sac. If the adjustment is not made properly, the pressure of the cleaning solution sprayed out by the conjunctival sac cleaning device may be too high in an instant, which may cause the device to not react in time and pose a risk of damaging the patient's eyes.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a conjunctival sac irrigation device, which solves the problem that improper pressure adjustment during cleaning of the conjunctival sac can easily cause damage to the eye.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A conjunctival sac irrigation device includes a main assembly, which includes a medicine bottle. One end of the medicine bottle is connected to a connecting tube, and the end of the connecting tube away from the medicine bottle is connected to an outer cylinder. The end of the outer cylinder away from the connecting tube is connected to an irrigation port. A micro pump is also installed on the connecting tube. A protective assembly is installed inside the outer cylinder. The protective assembly includes an inner cylinder disposed in the inner cavity of the outer cylinder. A spring is fixed to the bottom end of the inner cylinder cavity. A valve plate is fixed to the end of the spring away from the bottom end of the inner cylinder. A through hole is also opened on the outer periphery of the inner cylinder. A baffle is also installed on the through hole. A rack is fixed to the inner side of the baffle. A gear is also installed in the inner cavity of the inner cylinder. The gear meshes with the rack. A second rack is fixed to the valve plate. The second rack meshes with the gear.

[0008] Preferably, a gap is provided between the outer cylinder and the inner cylinder.

[0009] Preferably, the through hole, baffle, rack one, gear and rack two located on the same side are arranged as a group, and two groups are mirror-oriented.

[0010] Preferably, rack one and rack two in the same group are arranged in a centrally symmetrical manner with respect to the gear in that group.

[0011] Preferably, a limiting rod is also fixed at the bottom of the inner cavity of the inner cylinder, and a rack is movably disposed on the outer periphery of the limiting rod.

[0012] Preferably, a return pipe is also connected to one end of the outer cylinder. The connecting pipe has a first chamber and a second chamber. A one-way valve is installed in the second chamber. The end of the return pipe away from the outer cylinder is connected to the second chamber.

[0013] Compared with the prior art, the present invention provides a conjunctival sac irrigation device, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of a safety component, when the flushing pressure of the medicine exceeds the safety limit, the impact force of the medicine causes the valve plate to compress and move downward, driving the rack two to move, thereby driving the gear to rotate, causing the rack two to move, and finally driving the baffle to move. When the pressure is too high, the baffle will completely block the through hole, preventing the medicine from flowing out. This solves the problem in the existing solution that if the pressure is not properly adjusted when cleaning the conjunctival sac of the eye, it can easily cause damage to the eye.

[0015] 2. This utility model incorporates a safety component: a return pipe is connected to one end of the outer cylinder of the device. The connecting pipe contains a first chamber and a second chamber. A one-way valve is installed in the second chamber. The end of the return pipe away from the outer cylinder is connected to the second chamber. If the water pressure is too high, a baffle blocks the water flow, preventing it from spraying. The internal medicine liquid will then return to the medicine bottle through the one-way valve, preventing the micro pump from being damaged by excessive pressure and further improving its practicality.

[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] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a conjunctival sac irrigation device.

[0025] Please see Figure 1 - Figure 4 A conjunctival sac irrigation device includes a main component 1, which includes a medicine bottle 11. One end of the medicine bottle 11 is connected to a connecting tube 12, and the end of the connecting tube 12 away from the medicine bottle 11 is connected to an outer cylinder 14. The end of the outer cylinder 14 away from the connecting tube 12 is connected to an irrigation port 15. A micro pump 13 is also provided on the connecting tube 12. A protective component 2 is provided inside the outer cylinder 14, and the protective component 2 includes an inner cylinder 21 disposed inside the inner cavity of the outer cylinder 14. A spring element 22 is fixed at the bottom of the inner cavity of the inner cylinder 21. A valve plate 221 is fixed at the end of the spring element 22 away from the bottom of the inner cylinder 21. A through hole 23 is also provided on the outer periphery of the inner cylinder 21. A baffle 24 is also provided on the through hole 23. A rack 25 is fixed on the inner side of the baffle 24. A gear 252 is also provided in the inner cavity of the inner cylinder 21. The gear 252 meshes with the rack 25. A second rack 251 is also fixed on the valve plate 221. The second rack 251 meshes with the gear 252.

[0026] When using this device, it can be used normally as a traditional device. Hold the entire device and inject the flushing solution into the medicine bottle 11. Then, the flushing pressure is adjusted by the micro pump 13 to clean the conjunctival sac. It will not be described in detail here. Compared with traditional cleaning devices, this device is equipped with a special protective component 2. When the medicine is flushing the conjunctival sac of the eye under the drive of the micro pump 13, it will enter the outer cylinder 14 through the connecting tube 12, then enter the inner cylinder 21, and finally flow into the chamber between the outer cylinder 14 and the inner cylinder 21 through the through hole 23, and finally flow out from the flushing port 15. During this process, the medicine will continuously impact the valve plate 221. When the medicine flow pressure is greater than the safety limit, the impact force of the medicine will cause the valve plate 221 to compress and move downward, driving the rack 251 to move, which in turn drives the gear 252 to rotate, causing the rack 251 to move, and finally driving the baffle 24 to move. When the pressure is too high, the baffle 24 will completely block the through hole 23, so that the medicine will no longer flow out. Meanwhile, a certain gap is left between the end of the connecting pipe 12 inserted into the inner cylinder 21 and the through hole 23, which can prevent the pressure from being too high when adjusting the device for the first time, causing some of the liquid to spray out and the baffle 24 to be unable to stop it in time.

[0027] Furthermore, a gap is provided between the outer cylinder 14 and the inner cylinder 21, and the gap between the outer cylinder 14 and the inner cylinder 21 ensures that the cleaning solution can pass through during normal use.

[0028] Furthermore, the through hole 23, baffle 24, rack 1 25, gear 252 and rack 251 located on the same side are arranged as a group, and two groups are mirror-oriented. The two groups can better distribute the pressure and make the valve plate 221 move inward in a horizontal compression motion.

[0029] Furthermore, rack 1 25 and rack 251 in the same group are arranged symmetrically with respect to gear 252 in the same group. This causes gear 2521 and gear 2522 to move alternately, one moving downwards while the other moves in the opposite direction, ultimately pushing baffle 24 to isolate the cleaning solution.

[0030] Furthermore, a limiting rod 26 is fixed at the bottom of the inner cavity of the inner cylinder 21, and a rack 25 is movably disposed on the outer periphery of the limiting rod 26, so that the limiting rod 26 ensures that the rack 25 can move up and down normally.

[0031] Furthermore, a return pipe 27 is also connected to one end of the outer cylinder 14. A first chamber 121 and a second chamber 122 are opened in the connecting pipe 12. A one-way valve 28 is installed in the second chamber 122. The end of the return pipe 27 away from the outer cylinder 14 is connected to the second chamber 122. The opening and closing pressure of the one-way valve 28 is greater than the pressure of the spring 22. The pressure of the spring 22 is set to the maximum water flow impact pressure that the human eye can withstand. If the water flow pressure is too high, the baffle 24 blocks the water flow so that it stops spraying. Then the internal medicine liquid will flow back into the medicine bottle 11 through the one-way valve 28 to prevent the micro pump 13 from being damaged by excessive pressure.

[0032] Working Principle: This device is used normally, just like traditional equipment. Hold the entire device and inject the flushing solution into the medicine bottle 11. Then, the flushing pressure is adjusted by the micro pump 13 to clean the conjunctival sac. Further details are omitted here. Compared to traditional cleaning devices, this device has a dedicated protective component 2. Driven by the micro pump 13, the medicine flushes the conjunctival sac. The medicine enters the inner cylinder 21 through the connecting tube 12, then flows through the through hole 23 into the chamber between the outer cylinder 14 and the inner cylinder 21, and finally flows out from the flushing port 15. During this process, the medicine continuously impacts the valve plate 221. When the medicine flow pressure exceeds the safety limit, the impact force compresses the valve plate 221 downwards, driving the rack 251 to move, which in turn drives the gear 252 to rotate, causing the rack 251 to move, ultimately moving the baffle 24. When the pressure is too high, the baffle 24 will completely block the through hole 23, preventing the liquid medicine from flowing out. At the same time, a return pipe 27 is also connected to one end of the outer cylinder 14 of the device. The connecting pipe 12 has a chamber 121 and a chamber 22. A one-way valve 28 is installed in the chamber 22. The end of the return pipe 27 away from the outer cylinder 14 is connected to the chamber 22. The opening and closing pressure of the one-way valve 28 is greater than the pressure of the spring 22. The pressure of the spring 22 is set to the maximum water flow impact pressure that the human eye can withstand. If the water flow pressure is too high, the baffle 24 will block the water flow and prevent it from spraying. Then the internal liquid medicine will flow back into the liquid medicine bottle 11 through the one-way valve 28 to prevent the micro pump 13 from being damaged by excessive pressure.

[0033] 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.
