[0002] Traditional eye drop devices have relatively simple functions and can only achieve simple eye drop administration operations. In some situations where the eyes need to be flushed, medical staff often need to use additional devices to connect the eye drops to the needle, and the operation steps are cumbersome and difficult. For example, complex adapter equipment is required to connect the eye drops to the needle, which not only increases the preparation time and use costs, but may also lead to mistakes due to complex operations. At the same time, improper connection of the adapter equipment may lead to insufficient sealing and cause leakage.

[0003] Meanwhile, in some existing eye drop devices that can be connected to a needle, the needle and the middle cover are mostly prevented from falling off by interference fit. However, this method may not be able to fix the needle firmly enough in actual use, especially during the flushing process, the needle may become loose or even fall off due to external force, thus affecting the flushing effect and even causing damage to the patient's eyes.

[0004] Therefore, the traditional eye drop device with a single function cannot meet the requirements of the new eye drop device, which is to achieve convenient connection with the needle while ensuring sealing and safety. The market is in urgent need of a new eye drop device to solve the above problems and improve the convenience and safety of operation. Summary of the invention

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0032] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] See also Figures 1 to 7As shown, the present invention discloses a multifunctional eye drop device, including a liquid storage bottle 1, a connecting cover 2 and a protective cover 3, the liquid storage bottle 1 includes a bottle body 11 and a bottle mouth 12, a liquid storage cavity 111 is provided inside the bottle body 11, a first guide channel 121 is provided inside the bottle mouth 12, the first guide channel 121 is connected to the liquid storage cavity 111, and the liquid storage cavity 111 is used to store eye drops; the connecting cover 2 includes a cover body 21 and a connecting part 22, the cover body 21 is detachably connected to the bottle mouth 12, the connecting part 22 is used to connect the needle 4, and the connecting part 22 and the needle 4 are detachably connected; the inner diameter of the protective cover 3 matches the outer diameter of the connecting part 22, and the protective cover 3 is detachably connected to the connecting part 22.

[0034] Specifically, the multifunctional eye drop device in this embodiment is composed of three main parts: a liquid storage bottle 1, a connecting cover 2 and a protective cover 3. The liquid storage bottle 1 is divided into a bottle body 11 and a bottle mouth 12. The bottle body 11 has a liquid storage cavity 111 for storing eye drops. The bottle mouth 12 is provided with a first guide channel 121, which is connected to the liquid storage cavity 111 to provide a channel for the outflow of the medicine. The connecting cover 2 includes a cover body 21 and a connecting part 22. The cover body 21 can be detachably connected with the bottle mouth 12 to facilitate the assembly and disassembly of the connecting cover 2 and the liquid storage bottle 1. The connecting part 22 can be used for detachable connection with the needle 4, so that the device can be connected to the needle 4 as needed to complete the flushing function. The inner diameter of the protective cover 3 is adapted to the outer diameter of the connecting part 22, and the two are detachably connected. The protective cover 3 can protect the connecting part 22 when the needle 4 is not in use to avoid contamination. Furthermore, in this embodiment, the outer diameter of the cover body 21 is greater than the outer diameter of the connecting portion 22. The difference in the outer diameters of the cover body 21 and the connecting portion 22 forms a concave platform between the cover body 21 and the connecting portion 22, so as to provide a contact platform for the connection of the protective cover 3 in the later stage. It can be understood that this embodiment realizes the combination of the traditional eye drop function and the flushing function of the eye drop device by providing the connecting portion 22 that can be connected to the needle 4 in the eye drop device. When flushing the eye is required, the needle 4 is connected and flushing is performed using the medicine in the liquid storage chamber 111, without the need for additional special flushing devices, which greatly improves the versatility and use efficiency of the device.

[0035] In one embodiment, a first inner column 211 is extended downward from the top of the cover body 21, and the outer diameter of the first inner column 211 is larger than the inner diameter of the bottle mouth 12; the inner wall of the cover body 21 is screwed to the outer wall of the bottle mouth 12, and the outer wall of the first inner column 211 is sealed to the inner wall of the bottle mouth 12.

[0036] Specifically, the cover body 21 is mainly composed of the cover body 21 body and the first inner column 211 extending downward from the top of the cover body 21. The outer diameter of the first inner column 211 is greater than the inner diameter of the bottle mouth 12 to form an interference fit relationship, so that the outer wall of the first inner column 211 is in close contact with the inner wall of the bottle mouth 12 to prevent the eye drops from leaking from the connection between the connection cover 2 and the bottle mouth 12. It can be understood that the connection cover 2 is made of elastic material to ensure that the bottle mouth 12 is smoothly sleeved on the periphery of the first inner column 211 and there is no gap between the two for liquid to pass through. The inner wall of the cover body 21 is connected to the outer wall of the bottle mouth 12 by a threaded sleeve. The threaded connection can provide a certain friction and tightening force to ensure that the connection cover 2 will not fall off easily during use, thereby ensuring the overall stability of the device. The user can easily screw the connection cover 2 on the bottle mouth 12 or remove it from the bottle mouth 12, which is convenient for assembling and cleaning the eye drop device, thereby improving the durability and economy of the device. At the same time, the first inner column 211 extends downward from the top of the cover body 21 and matches the size and connection mode with the bottle mouth 12, making the structure of the entire eye drop device more compact. This compact design not only reduces the space occupied by the device, making it easier to carry and store, but also makes the device more beautiful in appearance.

[0037] In one embodiment, a second flow guiding channel 2111 is disposed in the first inner column 211 , and the second flow guiding channel 2111 is connected to the first flow guiding channel 121 .

[0038] Specifically, the first inner column 211 is a hollow structure, and a second flow guide 2111 is designed inside, and the second flow guide 2111 is interconnected with the first flow guide 121 of the bottle mouth 12, thereby forming a continuous channel starting from the liquid storage chamber 111 of the liquid storage bottle 1, passing through the first flow guide 121 of the bottle mouth 12, and then passing through the second flow guide 2111 in the first inner column 211. An orderly and smooth flow guide path is provided for eye drops. The medicine flowing out of the liquid storage chamber 111 can move smoothly along this continuous flow guide, ensuring the continuity of the medicine during the transmission process inside the device, avoiding obstruction or leakage of the medicine during the transmission process, and helping to accurately guide the medicine to the subsequent use site.

[0039] In one embodiment, the connecting portion 22 includes a dripper 221 and an outer column 222. The outer column 222 is arranged outside the dripper 221. A connecting groove 223 is formed between the dripper 221 and the outer column 222. The top horizontal plane of the outer column 222 is lower than the top horizontal plane of the dripper 221. The inner wall of the outer column 222 is provided with threaded threads.

[0040] Specifically, the connection part 22 is composed of a dripper 221 and an outer column 222, and the outer column 222 is arranged around the outside of the dripper 221, and the two together constitute the main structure of the connection part 22. A connection groove 223 is formed between the dripper 221 and the outer column 222. The connection groove 223 provides a specific spatial position for the subsequent connection of the needle 4 and other components in the structure. The needle 4 and other components can be inserted into the connection groove 223 and engaged with the inner wall of the outer column 222 to achieve an integrated connection with the eye drop device, thereby achieving a flushing function. The top horizontal plane of the outer column 222 is lower than the top horizontal plane of the dripper 221. This height difference design makes the dripper 221 relatively protruding in the connection part 22. On the one hand, it can avoid the outer column 222 from blocking the dripper 221, ensuring that the liquid can flow out smoothly during use, so as to facilitate the smooth operation of the eye drop function. On the other hand, the design of the outer column 222 surrounding the dripper 221 can protect the dripper 221, prevent the dripper 221 from being accidentally collided or damaged during use, and extend the service life of the dripper 221. The inner wall of the outer column 222 is provided with a thread pattern, and the setting of the thread pattern provides a specific connection method for the connection part 22, which can be used to be tightly connected with other components with corresponding thread structures, further enhancing the stability and reliability of the connection. At the same time, the setting of the thread pattern makes the connection part 22 universal and extensible, and in practical applications, it is convenient to connect and disassemble different types of components according to different usage requirements, meeting diverse medical needs.

[0041] In one embodiment, a liquid outlet channel 2211 and a liquid collecting chamber 2212 are sequentially provided in the dripper 221 from top to bottom, and the liquid outlet channel 2211, the liquid collecting chamber 2212 and the liquid storage chamber 111 are sequentially connected.

[0042] Specifically, in this embodiment, the vertical direction from the connecting cover 2 to the liquid storage bottle 1 is from top to bottom. The liquid outlet channel 2211 is directly responsible for guiding the liquid such as eye drops or flushing liquid to the use site. Its specific size and shape design can control the flow rate and flow rate of the liquid, ensure that the liquid can drip or flow out at an appropriate speed and amount, and improve the accuracy and safety of use. Further, in this embodiment, the liquid outlet channel 2211 preferably adopts an inverted cone structure, that is, the caliber of the liquid outlet channel 2211 gradually increases from the liquid inlet of the liquid outlet channel 2211 to the liquid outlet of the liquid outlet channel 2211. This gradually increasing caliber design can reduce the resistance of the liquid flowing in the liquid outlet channel 2211. When the liquid flows from the liquid inlet of the liquid outlet channel 2211 to the liquid outlet of the liquid outlet channel 2211, due to the continuous increase in the caliber of the liquid outlet channel 2211, the liquid can flow out more smoothly, which improves the flow rate and flow rate of the liquid, making the eye drop or flushing operation more efficient.

[0043] The liquid collecting chamber 2212 plays a role of transition and buffering. When the liquid in the liquid storage chamber 111 flows into the dripper 221, the liquid collecting chamber 2212 can temporarily store a certain amount of liquid, so that the liquid has a stable gathering space before flowing out, thereby avoiding the instability of the liquid flow and ensuring that the liquid can continue to flow out through the liquid outlet channel 2211. The sequential connection of the liquid storage chamber 111, the liquid collecting chamber 2212 and the liquid outlet channel 2211 ensures that the liquid can flow smoothly from the storage to the use process without blockage or interruption. The user can make the liquid flow smoothly from the liquid storage chamber 111 through the dripper 221 through simple operations, such as squeezing the liquid storage bottle 1, without complicated operation steps.

[0044] In one embodiment, the needle 4 includes a needle tube 41 and a connector 42 . The connector 42 is sleeved on the outer wall of the dripper 221 and is snapped into the connecting groove 223 so that the needle tube 41 is connected to the dripper 221 .

[0045] Specifically, the needle tube 41 is responsible for conveying liquid to achieve the flushing function. The connector 42 is used to connect to the dripper 221 of the eye drop device. The connector 42 is sleeved on the outer wall of the dripper 221, and can be snapped into the connecting groove 223 formed between the dripper 221 and the outer column 222. Through this connection method, the needle tube 41 is connected to the dripper 221. When the needle 4 is connected to the eye drop device, the flushing function is added to the device, and the original single eye drop function is expanded. Users can choose to directly use the dripper 221 to achieve the eye drop mode or install the needle 4 to achieve the flushing mode according to different needs, which improves the applicability and practicality of the device. At the same time, this connection method allows the eye drop device to be connected to the needle 4 without the aid of other complex adapter equipment, simplifies the operation steps, and facilitates users to quickly switch functions in different scenarios.

[0046] In one embodiment, a clamping wall 421 is extended outward from the bottom of the connector 42 , and the clamping wall 421 is clamped to the threaded thread of the inner wall of the outer column 222 .

[0047] Specifically, the connection between the clamping wall 421 and the screw thread provides an additional fixing point for the connection between the needle 4 and the eye drop device, so that the needle 4 is more firmly connected to the eye drop device during use, and is not easy to loosen or fall off, ensuring the stability of liquid delivery. The screw connection between the clamping wall 421 and the outer column 222 makes the installation and removal of the needle 4 relatively simple. The user can quickly engage or separate the clamping wall 421 and the screw thread by rotating or pressing, which is convenient for replacing the needle 4 or cleaning and maintenance when necessary. At the same time, the tight clamping of the clamping wall 421 and the screw thread can enhance the sealing performance and connection strength of the connection part to a certain extent, reduce the possibility of liquid leakage from the connection part 22, ensure that the eye drop medicine or flushing liquid can be accurately delivered to the desired part through the needle 4, and at the same time, the needle is locked by the screw thread, effectively preventing the needle from falling off during use, and improving the safety and effectiveness of use.

[0048] In one embodiment, the outer diameter of the dripper 221 is larger than the inner diameter of the connector 42 , so that the outer wall of the dripper 221 and the inner wall of the connector 42 are sealed and connected.

[0049] Specifically, the size difference between the outer diameter of the dripper 221 and the inner diameter of the connector 42 enables the dripper 221 and the connector 42 to achieve an interference fit connection, and the outer wall of the dripper 221 and the inner wall of the connector 42 can fit tightly, thereby effectively preventing the eye drops or flushing liquid from leaking out from the connecting portion 22 during the delivery process. At the same time, this interference fit connection method can withstand certain external forces, such as slight pulling and squeezing that may be encountered during use, to ensure that the connection between the needle 4 and the dripper 221 will not easily loosen or fall off.

[0050] Furthermore, in the present embodiment, the connection cover 2 is an integrally formed structure, and the connection cover 2 is preferably made of an elastic material, so as to ensure smooth connection and sealing effect of the entire eye drop device during use.

[0051] In one embodiment, the protective cover 3 includes a cap portion 31 and a second inner column 32 disposed on the top of the cap portion 31 and extending downward, the second inner column 32 is a hollow structure, the second inner column 32 is snapped into the connecting groove 223, and the outer wall of the second inner column 32 is threadedly connected to the inner wall of the outer column 222.

[0052] Specifically, the second inner column 32 in the protective cover 3 is snapped into the connection groove 223 formed between the dripper 221 and the outer column 222 in the connecting portion 22. This snap-on method enables the protective cover 3 to be quickly and firmly combined with the connecting portion 22 to prevent the protective cover 3 from accidentally falling off when not in use. The outer wall of the second inner column 32 is threadedly connected to the inner wall of the outer column 222. The threaded connection provides a more stable connection, ensuring that the protective cover 3 will not easily loosen after installation, further enhancing the connection strength between the protective cover 3 and the connecting portion 22. It can be understood that when the eye drop device is not in use, the protective cover 3 completely covers the connecting portion 22, including key parts such as the dripper 221 and the outer column 222. The hollow structure of the second inner column 32 and the cap portion 31 work together to effectively prevent external dust, bacteria and other impurities from entering the connecting portion 22, keep the connecting portion 22 clean, and avoid contamination of the eye drops when used next time.

[0053] In one embodiment, the inner diameter of the second inner column 32 is smaller than the outer diameter of the dripper 221 , so that the outer wall of the dripper 221 and the inner wall of the second inner column 32 are sealed.

[0054] Specifically, through the size difference between the inner diameter of the second inner column 32 of the protective cover 3 and the outer diameter of the dripper 221, the dripper 221 and the protective cover 3 are connected by interference fit, and the outer wall of the dripper 221 can fit tightly with the inner wall of the second inner column 32, thereby achieving a sealed connection. It can be understood that in this embodiment, the liquid outlet of the dripper 221 is also tightly connected to the bottom wall of the protective cover 3, thereby further achieving a sealing effect. When the protective cover 3 is installed on the connecting portion 22, the sealed connection between the dripper 221 and the second inner column 32 can effectively prevent external impurities from entering the interior of the eye drop device, thereby maintaining the purity of the eye drop medicine and avoiding the quality and use effect of the medicine being affected by impurity contamination. At the same time, a good sealed connection can prevent the eye drop medicine from leaking out from the dripper 221 during storage or carrying, reducing the waste of medicine and the impact on the surrounding environment.

[0055] It can be understood that, in this embodiment, the eye drop device includes three states:

[0056] When performing the eye drop operation, the cover body 21 of the connecting cover 2 is tightly connected to the bottle mouth 12 of the liquid storage bottle 1 to ensure the sealing of the liquid storage bottle 1. The eye drop medicine in the liquid storage chamber 111 flows to the dripper 221 through the first guide channel 121 of the bottle mouth 12 and the second guide channel 2111 of the first inner column 211 of the connecting cover 2. The liquid collection chamber 2212 in the dripper 221 collects and buffers the medicine, and then the medicine drips out through the liquid outlet channel 2211 and accurately drips into the eye to complete the eye drop process. In this state, the protective cover 3 is removed and the needle 4 is not connected.

[0057] When performing the flushing operation, firstly, the connector 42 of the needle 4 is sleeved on the outer wall of the dripper 221, and the clamping wall 421 at the bottom of the connector 42 is clamped on the threaded pattern of the inner wall of the outer column 222 of the connecting part 22, so that the needle tube 41 is connected with the dripper 221. The liquid storage bottle 1 is squeezed, and the medicine in the liquid storage cavity 111 passes through the first guide channel 121, the second guide channel 2111, the liquid collecting cavity 2212, the liquid outlet channel 2211 in sequence, flows through the needle tube 41, and is ejected from the needle to flush the eyes. In this state, the protective cover 3 is removed.

[0058] When not in operation, the second inner column 32 of the protective cover 3 is clamped in the connection groove 223, and the outer wall of the second inner column 32 is threadedly connected to the inner wall of the outer column 222, and the outer wall of the dripper 221 is sealed and connected to the inner wall of the second inner column 32, thereby achieving a sealed connection between the protective cover 3 and the connection cover 2. This connection method can effectively prevent dust, bacteria and other pollutants from entering the connection part 22 and the dripper 221, protect the cleanliness of the inside of the eye drop device, and prepare for the next use. In this state, the needle 4 is not connected.

[0059] Among them, in this embodiment, the description of the upper and lower positions is based on the position of the eye drop device in this embodiment standing on a horizontal plane, that is, from top to bottom, they are: the protective cover 3, the connecting cover 2 and the liquid storage bottle 1.

[0060] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
