Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, and more specifically to a rinsing connection structure. Background Technology

[0002] In the field of eye care and treatment, the use of eye drops is often accompanied by rinsing procedures. Currently, existing rinsing structures on the market have several shortcomings in their connection design. On the one hand, the assembly process of most rinsing structures is complex, involving cumbersome connection steps for multiple components. For example, installing the rinsing element and its corresponding connecting parts often requires a complicated procedure, which is not only time-consuming but also demands a high level of skill from the operator. On the other hand, the connections of these rinsing structures are not very secure, and loosening is prone to occur during daily use or transportation, affecting the normal use and lifespan of the rinsing structure. Inconvenient and unstable connections during frequent use of the rinsing structure can lead to reduced work efficiency. Moreover, in non-professional medical environments, such as home eye care, complex and unstable connections can also cause inconvenience to users. Furthermore, due to the inherent connection problems of the rinsing structure itself, unexpected situations may occur during rinsing, such as eye drop leakage or detachment of the rinsing element, thus affecting the rinsing effect and potentially causing damage to the eyes. Therefore, there is an urgent need for a new eye drop rinsing structure with a simple, quick, and secure connection method to meet the needs of practical applications. Utility Model Content

[0028] See Figures 1 to 4As shown, this utility model discloses a flushing connection structure connected to a liquid storage device, including a connecting cover 1 and a flushing component. The flushing component is detachably connected to the connecting cover 1. The connecting cover 1 includes a connecting part 11 and a functional part 12. The connecting part 11 is connected to the liquid storage device, and the functional part 12 is connected to the flushing component. The functional part 12 includes a connecting wall 121 and a liquid outlet pipe 122 disposed within the connecting wall 121. The flushing component is sleeved on the outer wall of the liquid outlet pipe 122.

[0029] Specifically, the flushing connection structure in this embodiment mainly consists of a connecting cover 1 and a flushing component, and is designed to connect to the liquid storage device to realize the flushing function of eye drops. The main function of the connecting part 11 is to establish a connection with the liquid storage device. Its shape and size are adapted to the interface shape and size of the liquid storage device to ensure a stable connection. The functional part 12 mainly consists of a connecting wall 121 and a liquid outlet pipe 122. The connecting wall 121 surrounds the liquid outlet pipe 122, and together with the liquid outlet pipe 122, they form a spatial structure for accommodating and connecting the flushing component. The liquid outlet pipe 122 is located inside the connecting wall 121 and is the channel for eye drops or eye drops to flow from the liquid storage device to the flushing component. The flushing component and the connecting cover 1 are detachably connected. The flushing component is sleeved on the outer wall of the liquid outlet pipe 122, which facilitates the replacement and maintenance of the flushing component. For example, when the flushing component is damaged or different types of flushing components (such as needles 2 of different diameters) are needed, it can be easily replaced. During use, medical staff or users can quickly prepare the flushing structure or replace the flushing components when needed, saving time and effort. This is especially beneficial in frequently used medical environments, significantly improving work efficiency. It is understood that the outer wall of the discharge pipe 122 specifically refers to the side of the discharge pipe 122 closest to the connecting wall 121.

[0030] In one embodiment, a connecting groove 123 is formed between the connecting wall 121 and the liquid outlet pipe 122, and a snap-fit ​​post 1211 is provided on the side of the connecting wall 121 near the liquid outlet pipe 122, and the flushing component is snapped into the snap-fit ​​post 1211.

[0031] Specifically, the connecting groove 123 formed between the connecting wall 121 and the outlet pipe 122 provides a certain amount of space for the connection between the flushing component and the connecting cover 1, allowing the flushing component to be placed and positioned appropriately during installation. The shape, size, and position of the snap-fit ​​post 1211 provided on the side of the connecting wall 121 near the outlet pipe 122 are designed to provide a stable snap-fit ​​support point for the flushing component. Moreover, the snap-fit ​​post 1211 can take different forms according to different design requirements, such as making the snap-fit ​​more secure and stable.

[0032] In one embodiment, the flushing component is a needle 2, which includes a needle tube 21 and a connecting tube 22. The needle tube 21 is connected to the top of the connecting tube 22, and the bottom of the connecting tube 22 extends outward with a snap-fit ​​wall 221.

[0033] Specifically, the needle 2, serving as the rinsing component, consists of two parts: a needle tube 21 and a connecting tube 22. The needle tube 21, located at the top of the entire needle 2, is the part directly used for rinsing, ensuring no damage to the eye during rinsing while effectively delivering the eye drops. The connecting tube 22 connects the needle tube 21 to the rest of the rinsing structure, ensuring the eye drops flow sequentially from the reservoir through the outlet tube 122 of the connecting cap 1, the connecting tube 22, and finally out of the needle tube 21. The snap-fit ​​wall 221 is an annular wall extending outward from the bottom of the connecting tube 22, ensuring effective engagement with the snap-fit ​​post 1211 of the connecting cap 1 in all directions. This makes the needle 2 less prone to deformation or detachment under eye drop pressure and external force, thus ensuring the stability of the needle 2 during rinsing.

[0034] In one embodiment, the snap-fit ​​wall 221 snaps into the snap-fit ​​post 1211.

[0035] Specifically, when the locking wall 221 engages with the locking post 1211, the top of the locking wall 221 abuts against the bottom of the locking post 1211 to secure them together. The locking post 1211 is made of an elastic material or has a certain degree of deformation capability, so that the locking wall 221 can smoothly and tightly fit with the locking post 1211 during the engagement process. This ensures that the needle 2 will not easily detach from the connecting cap 1 during use, regardless of the pressure generated by the flow of eye drops or slight external impacts or vibrations, thus ensuring the continuity and safety of the flushing operation. When it is necessary to replace the needle 2 or perform cleaning and maintenance, the user can easily detach the locking wall 221 from the locking post 1211, greatly improving operational efficiency.

[0036] In one embodiment, the outer diameter of the outlet pipe 122 is larger than the inner diameter of the connecting pipe 22.

[0037] Specifically, when the snap-fit ​​post 1211 is designed as a threaded post, its surface has a spiral pattern. During the connection process, the snap-fit ​​wall 221 gradually and tightly engages with the threaded post by rotating or advancing along the spiral direction of the threaded post until the top of the snap-fit ​​wall 221 abuts against the bottom of the threaded post to secure the needle 2. Simultaneously, the threaded connection offers high installation accuracy. During installation, the snap-fit ​​wall 221 gradually screws in along the spiral direction of the threaded post, ensuring that the flushing component is accurately installed in the predetermined position, maintaining good alignment and sealing with the outlet tube 122.

[0038] In one embodiment, the outer diameter of the outlet pipe 122 is larger than the inner diameter of the connecting pipe 22.

[0039] Specifically, when the connecting tube 22 is fitted onto the outer wall of the outlet tube 122, a certain degree of compression occurs between them, forming an interference fit, making the connection between the outlet tube 122 and the connecting tube 22 very tight. During the rinsing process, even under the pressure of the eye drops and slight external vibrations, the connecting tube 22 will not easily detach or loosen from the outlet tube 122. At the same time, due to the interference fit between the outlet tube 122 and the connecting tube 22, the gap between them is very small, which can effectively prevent the leakage of eye drops, reduce the waste of eye drops, and avoid the contamination or irritation of the patient's eye area caused by eye drop leakage.

[0040] In one embodiment, the outer diameter of the outlet pipe 122 gradually increases from the outlet of the outlet pipe 122 to the inlet of the outlet pipe 122.

[0041] Specifically, the gradually changing outer diameter of the outlet pipe 122 can enhance the connection stability with the flushing component connecting pipe 22. When the outlet pipe 122 is connected to the flushing component connecting pipe 22, the connecting pipe 22 is sleeved on the outlet pipe 122 with the gradually increasing outer diameter, which can form a step-like nested structure in the sleeved part, increasing the firmness of the connection and ensuring that the connecting pipe 22 will not easily fall off during the flushing process.

[0042] In one embodiment, the liquid outlet pipe 122 is provided with a liquid outlet channel 1221, which is connected to the rinsing component.

[0043] Specifically, an outlet channel 1221 is provided inside the outlet pipe 122, extending through the outlet pipe 122 and communicating with the rinsing device. The connecting pipe 22 of the rinsing device may be tightly fitted at the outlet of the outlet pipe 122, allowing the outlet channel 1221 to directly connect with the channel inside the connecting pipe 22. This ensures that the eye drops can flow smoothly from the outlet pipe 122 into the rinsing device, avoiding turbulent flow or blockage of the eye drops within the outlet pipe 122. The eye drops can flow in the outlet channel 1221 in a predetermined direction and speed, smoothly transporting them from the storage device to the rinsing device, ensuring the continuity and stability of the rinsing operation.

[0044] In one embodiment, the horizontal height of the outlet of the liquid outlet pipe 122 is higher than the horizontal height of the top of the connecting wall 121.

[0045] Specifically, the outlet of the liquid outlet pipe 122 is positioned higher than the top horizontal level of the connecting wall 121, making it easier for users to observe the position of the connecting flushing components when using the flushing structure, thereby enabling quick installation and flushing operations, and greatly improving work efficiency.

[0046] In one embodiment, the connecting cover 1 is integrally injection molded from a flexible material.

[0047] Specifically, the connecting cap 1 is made of a flexible material using a one-piece injection molding process. The flexible material is elastic and deformable, allowing the connecting cap 1 to better fit with the liquid storage device and flushing component, forming a good seal and ensuring that the eye drops do not leak from the connection point, thus improving the overall sealing performance of the flushing structure. Simultaneously, due to the deformability of the flexible material, the connecting cap 1 can adapt to liquid storage devices and flushing components of different sizes and shapes. Whether it is a standard-sized liquid storage device or a specially shaped flushing component, the connecting cap 1 can achieve a tight connection through its own elastic deformation, increasing the versatility and applicability of the flushing structure. It is understood that the flexible material in this embodiment also has a certain degree of hardness to ensure the connection strength between the connecting cap and the flushing component, and between the connecting cap and the liquid storage device. The one-piece injection molding process makes the production process of the connecting cap 1 more efficient and convenient. By designing a suitable mold, the complex structure of the connecting cap 1 can be molded in one go, reducing assembly and processing steps and avoiding leakage caused by gaps in assembly. It is understood that the flexible material can be plastic, hard silicone, or other polymer materials with similar properties.
