Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable-angle eye irrigation device with waste liquid collection function. Background Technology
[0002] In ophthalmic emergencies, chemical burn treatment, and pediatric eye care, eye irrigation is a crucial step in removing foreign objects or harmful substances. Traditional eye irrigation devices often use handheld irrigation bottles or simple nozzle structures.
[0003] In existing devices, the waste liquid after rinsing flows directly into the tray or the ground, causing foreign objects (such as chemical particles, eyelashes, or secretions) to be lost with the waste liquid. Medical staff cannot directly observe the nature of the foreign objects, affecting subsequent diagnosis and medication decisions. Although some improved devices are equipped with collection containers, they lack a filtration structure, and fine particulate matter still mixes into the waste liquid, requiring manual secondary screening, which is inefficient and poses a risk of cross-contamination. Children are prone to shaking their heads due to fear or pain, causing the rinsing fluid and waste liquid to splash, polluting the environment and increasing the risk of secondary eye infections.
[0004] Therefore, there is an urgent need for an adjustable-angle eye irrigation device with waste fluid collection function to solve the problems of difficult foreign body analysis, waste fluid leakage and low irrigation efficiency in clinical operation, while improving the comfort and safety of patients (especially children).

[0029] The following is in conjunction with the appendix Figures 1-5 The specific embodiments of this utility model will be described in further detail.
[0030] Example 1, by Figures 1-5The device includes a waste liquid bottle 1, which can be a used water bottle or a dedicated storage bottle, mainly used to collect waste liquid generated from rinsing the eyes. It also includes an eye mask 2, which is a thin-walled, hollow structure made of transparent material. The eye mask 2 is placed over the patient's eye that needs rinsing. The transparency allows for easy adjustment of the rinsing angle. A filter assembly 3 is connected to the lower end of the eye mask 2, and the lower end of the filter assembly 3 is connected to the waste liquid bottle 1. The filter assembly 3 is used to filter foreign objects in the waste liquid, allowing for observation of the nature of any foreign objects entering the eye after rinsing, facilitating the selection of appropriate medications for treatment. A corrugated hose 4 is fixedly connected to the front end of the eye mask 2, and a mounting plate 5 is fixedly connected to the side away from the eye mask 2. The corrugated hose is made of flexible material. A detachable rinsing tube 6 is installed at the end of the mounting plate 5. The rinsing tube 6 can output rinsing fluid, which can be purified water, saline solution, or other liquids suitable for rinsing the eyes. The angle of the rinsing tube 6 relative to the eye mask 2 can be adjusted via the corrugated hose 4.
[0031] When in use, the goggles 2 are placed on the patient's eye that needs to be rinsed, and the rinsing tube 6 is inserted into the mounting plate 5 so that the water outlet enters the goggles 2. The operator holds the end of the rinsing tube 6 to control the rinsing fluid to rinse the patient's eye. At the same time, the waste liquid generated by rinsing will flow into the waste liquid bottle 1 through the filter assembly 3. The foreign objects that are rinsed out will be stored in the filter assembly 3. After the medical staff removes the foreign objects, they will observe whether the eye needs to be treated with medication.
[0032] Example 2, based on Example 1, is... Figures 2-4 To achieve the purpose of filtering out foreign objects, the filtering component 3 includes a connecting tube 31, which is fixedly connected to the lower end of the goggles 2 and communicates with the inside of the goggles 2. The inner diameter of the connecting tube 31 is larger than the inner diameter of the rinsing tube 6 to prevent liquid from remaining in the goggles 2. The lower end of the connecting tube 31 is detachably connected to a plug sleeve 32. The other end of the plug sleeve 32 is connected to the waste liquid bottle 1 through a hose. When in use, the liquid in the goggles 2 enters the connecting tube 31 and then flows along the plug sleeve 32 and the hose to the waste liquid bottle 1. It should be noted that the upper end of the waste liquid bottle 1 is provided with an air vent to allow the waste liquid to enter the waste liquid bottle 1 smoothly.
[0033] To ensure the smooth flow of waste liquid, a fixed filter screen 33 is fixedly connected to the middle of the insertion sleeve 32. The filter screen 33 is funnel-shaped with an upward opening and an open bottom. A sliding filter screen 34 is provided at the lower end of the fixed filter screen 33. Both the fixed filter screen 33 and the sliding filter screen 34 are made of metal and have a certain degree of rigidity. The sliding filter screen 34 is placed inside the insertion sleeve 32 and can slide up and down relative to the insertion sleeve 32. The sliding filter screen 34 is conical and has an downward opening. The middle part of the sliding filter screen 34 can block the opening at the bottom of the fixed filter screen 33.
[0034] During use, the waste liquid passes through the fixed filter screen 33 and the sliding filter screen 34, and foreign objects in the waste liquid will enter the upper end of the sliding filter screen 34 through the middle of the fixed filter screen 33. After rinsing, the insert sleeve 32 is separated from the connecting pipe 31, and the sliding filter screen 34 will slide upward, so that the middle of the sliding filter screen 34 blocks the middle of the fixed filter screen 33. At this time, the filtered foreign objects will remain between the sliding filter screen 34 and the fixed filter screen 33.
[0035] It should be noted that, in order to facilitate observation of whether foreign objects have been expelled, the insertion sleeve 32 is made of transparent material.
[0036] Example 3, based on Example 2, by Figures 2-4 To achieve better results, a support spring 35 is fixedly connected to the lower end of the sliding filter 34, and the other end of the support spring 35 is fixedly connected to the bottom of the insertion sleeve 32. The support spring 35 is used to push the sliding filter 34 to slide upward. A plurality of pressing rods 36 are fixedly connected to the upper end of the sliding filter 34. Each pressing rod 36 passes through the fixed sleeve and can abut against the lower end of the connecting pipe 31. In use, the insertion sleeve 32 is installed at the lower end of the connecting pipe 31, and the middle part of the connecting pipe 31 is pushed by the pressing rods 36 to push the sliding filter 34 downward, so that the sliding filter 34 is separated from the fixed filter 33. After rinsing, when the insertion sleeve 32 is removed from the end of the connecting pipe 31, the support spring 35 pushes the sliding filter 34 to slide upward and reset.
[0037] Example 4, based on Example 2, by Figures 2-4 To facilitate operation, multiple positioning protrusions 37 are fixedly connected to the outer side of the connecting pipe 31. The positioning protrusions 37 are circular arc surfaces. Multiple through positioning holes 38 are opened on the side wall of the insertion sleeve 32. The positioning holes 38 correspond one-to-one with the positioning protrusions 37. Each positioning protrusion 37 can be inserted into the corresponding positioning hole 38. The upper end of the insertion sleeve 32 has a bevel corresponding to the position of the positioning hole 38 to facilitate the insertion of the positioning protrusion 37 into the positioning hole 38. The positioning protrusions 37 and the positioning holes 38 cooperate to form a limiting structure for the insertion sleeve 32. In use, the positioning holes 38 are aligned with the positioning protrusions 37, and then the insertion sleeve 32 is pushed upward to allow the positioning protrusions 37 to enter the positioning holes 38 to complete the limiting of the insertion sleeve 32. After use, the insertion sleeve 32 is pulled downward to separate it from the connecting pipe 31.
[0038] It should be noted that a notch is provided in the middle of the insertion sleeve 32 so that the position of the positioning insertion hole 38 can be elastically deformed, so as to facilitate the connection between the insertion sleeve 32 and the connecting pipe 31.
[0039] Example 5, based on Example 1, by Figures 1-5To facilitate angle adjustment, a limiting disc 7 is fixedly connected to the outer side of the flushing tube 6. The limiting disc 7 has multiple limiting notches 8 circumferentially oriented. A limiting ring 9 is formed in the middle of the mounting plate 5. The limiting ring 9 protrudes at the position corresponding to the limiting notches 8, allowing the limiting disc 7 to be fixed within it. The limiting disc 7 can be inserted into and rotate relative to the limiting ring 9. A circular tube is fixedly connected inside the mounting plate 5, and the flushing tube 6 passes through the inner side of the circular tube. During use, the end of the flushing tube 6 is held by hand. Insert it into the mounting plate 5 and hang the round tube through it. Then adjust the position of the limiting notch 8 to correspond with the protrusion of the limiting ring 9. Insert the limiting plate 7 into the limiting ring 9 and rotate it at an appropriate angle. Then you can rinse and adjust the angle of the rinsing pipe 6. The end of the rinsing pipe 6 is connected to the liquid inlet hose 10. The liquid inlet hose 10 is used to deliver rinsing liquid into the rinsing pipe 6. In use, the other end of the liquid inlet hose 10 is connected to a water pump or other components that can deliver liquid into it. This is existing technology and will not be described in detail here. It is also not shown in the figure.
[0040] Example 6, based on Example 1, by Figures 1-5 To facilitate fixation, the eye mask 2 is circumferentially fixed with multiple positioning stickers 11 at its rear end. These stickers can be adhered to the patient's face to fix the eye mask 2 in place without the need for hand support, making it easier for doctors to operate. For patients whose eyes cannot be opened actively, a traction sticker 12 is provided on the upper rear end of the eye mask 2. The upper end of the traction sticker 12 penetrates the side wall of the eye mask 2. When in use, the lower end of the traction sticker 12 is adhered to the patient's upper eyelid. During use, pulling the traction sticker 12 upward exposes the patient's upper eyelid, making it easier to rinse foreign objects from the eyes.
[0041] In use, the positioning socket 38 is aligned with the positioning boss 37. Then, the insertion sleeve 32 is pushed upward to allow the positioning boss 37 to enter the positioning socket 38 and complete the positioning of the insertion sleeve 32. Then, the hose is connected to the waste liquid bottle 1. Next, the eye mask 2 is placed on the patient's eye that needs to be rinsed. After adjusting the position, the eye mask 2 is attached to the patient's face through the positioning sticker 11. Then, the end of the rinsing tube 6 is held and inserted into the mounting plate 5 and the round tube is hooked through it. Then, the position of the limiting notch 8 is aligned with the protrusion of the limiting ring 9. The limiting plate 7 is inserted into the limiting ring 9 and rotated at an appropriate angle. If necessary, the lower end of the traction sticker 12 is attached to the patient's upper eyelid. During use, the patient's upper eyelid is exposed by pulling the traction sticker 12 upward. Then, rinsing fluid is injected into the inlet hose 10 to flush out foreign objects in the patient's eye. The waste liquid generated during rinsing the eye will enter the waste liquid bottle 1 through the filter assembly 3.
[0042] When the insert sleeve 32 is installed at the lower end of the connecting tube 31, the middle part of the connecting tube 31 pushes the sliding filter 34 downward through the pressing rod 36, causing the sliding filter 34 to separate from the fixed filter 33. The waste liquid passes through the fixed filter 33 and the sliding filter 34, and foreign objects in the waste liquid will enter the upper end of the sliding filter 34 through the middle of the fixed filter 33. After rinsing, the insert sleeve 32 is removed, and the support spring 35 pushes the sliding filter 34 upward to reset, so that the middle of the sliding filter 34 blocks the middle of the fixed filter 33. At this time, the filtered foreign objects will remain between the sliding filter 34 and the fixed filter 33, so as to facilitate observation of the nature of the foreign objects entering the eye after rinsing, and to facilitate the selection of appropriate drugs to treat the patient's eyes.
[0043] This utility model has a novel structure, ingenious design, and simple and convenient operation. It effectively filters foreign objects, optimizes the fixation effect, avoids the problem of waste liquid leakage, and improves the effect of adjusting the rinsing angle.
