Description

Technical Field

[0001] This utility model belongs to the field of medical technology, specifically relating to a backflow-proof eye drop water bottling system. Background Technology

[0002] Traditional eye drop packaging primarily uses multi-dose bottles made of glass or plastic, dispensing the medication via dropper or by squeezing the bottle. However, the contamination rate of traditional bottled eye drops can reach 35% after 28 days of opening, posing a significant risk, especially to immunocompromised patients. Small-volume eye drops are typically used within one day; smaller packaging improves sterility and effectively reduces the risk of infection.

[0003] CN201320304244.X discloses a disposable eye drop bottle, including a bottle body and a cap. The cap has a recessed hole at its bottom, and an annular protrusion is formed on the inner wall of the bottom of the recessed hole. The bottom surface of the annular protrusion is formed together with the top surface of the bottle neck. The recessed hole communicates with the bottle neck, and an annular groove is formed on the outer wall of the bottle neck. Although the cap can be repeatedly and securely fixed to the bottle body for reuse of the eye drops after being unscrewed, the bottle only has one storage cavity. When used multiple times, there is still a certain risk of infection. Furthermore, the lack of a backflow prevention structure allows air, microorganisms, or contaminants to flow back into the bottle, causing secondary contamination of the eye drops and loss of efficacy, thus increasing the risk of infection. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a backflow-proof eye drop water bottling system. By setting multiple drug storage chambers inside the bottle, single-dose isolation is achieved, reducing the risk of infection.

[0005] In this embodiment of the invention, a backflow-proof eye drop water bottling system includes a bottle body and a cap that is detachably and sealingly connected to the bottle body. The bottle body has a check valve in the neck that allows fluid to flow outward only from the bottle opening. Multiple diaphragms are spaced apart along the length of the bottle body, dividing the bottle body into multiple independent drug storage chambers. Needle-punched parts are provided on the inner wall of the bottle body at positions corresponding to the diaphragms. The bottle body is made of a soft material. By squeezing the bottle body at the positions corresponding to the needle-punched parts, the diaphragms can be punctured by the corresponding needle-punched parts.

[0006] Compared with the prior art, the beneficial effects of the superior technical solution of this utility model include:

[0007] 1. This utility model achieves true single-dose isolation by setting multiple diaphragms inside the bottle to form multiple independent drug storage chambers. Compared with the existing technology that stores eye drops in one drug storage chamber, this utility model reduces the risk of infection.

[0008] 2. By setting a check valve, the backflow of air, microorganisms or pollutants into the bottle is blocked, avoiding secondary contamination of the eye drops and loss of efficacy, and further reducing the risk of infection.

[0009] 3. By setting needles at the corresponding positions of the diaphragm, the diaphragm will only be punctured when the bottle is squeezed at the corresponding position of the needle, ensuring that the diaphragm will not break prematurely.

[0010] 4. By setting up a flexible connecting strip, the cover can be prevented from being lost, and the cover can be prevented from rolling to the ground and causing pollution. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the anti-backflow eye drop water bottling structure of an embodiment.

[0012] The reference numerals in the accompanying drawings include: bottle body 1, cap body 2, diaphragm 3, medicine storage chamber 4, needle-punching part 5, neck 6, flat labeling area 7, flexible connecting strip 8, check valve 9. Detailed Implementation

[0013] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0014] This embodiment provides a backflow-preventing method for bottling eye drops, such as... Figure 1 As shown, in a preferred embodiment, it includes a bottle body 1 and a cap 2 detachably and sealingly connected to the bottle body 1. The bottle body 1 has a check valve 9 in the neck 6 that allows fluid to flow outward from the bottle opening. Multiple diaphragms 3 are spaced apart along the length of the bottle body 1, dividing the bottle body 1 into multiple independent drug storage chambers 4. A needle-punched part 5 is provided on the inner wall of the bottle body 1 at the position corresponding to the diaphragm 3. The bottle body 1 is made of soft material. By squeezing the position of the needle-punched part of the bottle body 1, the diaphragm 3 can be punctured by the corresponding needle-punched part 5.

[0015] For first-time use, open cap 2 from bottle 1, invert bottle 1, and gently squeeze the position of bottle 1 corresponding to the uppermost medicine storage chamber 4 to dispense the eye drops from that chamber. After use, close cap 2 to seal the bottle. For second-time use, align the needle part 5 corresponding to the diaphragm 3 at the top of the second medicine storage chamber 4, and squeeze bottle 1 to puncture the diaphragm 3. Then open cap 2, invert bottle 1 to dispense the eye drops, and close cap 2 after use. The method for using the eye drops in the subsequent medicine storage chambers 4 is the same as described above and will not be repeated.

[0016] When the eye drops are dispensed by squeezing bottle 1, the check valve 9 allows the eye drops to flow outward under pressure. After the pressure is released, it automatically seals, preventing air, microorganisms, or contaminants from flowing back into bottle 1, thus avoiding secondary contamination and drug inactivation. Specifically, the check valve 9 can be a duckbill silicone valve commonly used in the medical field (when the bottle is squeezed, the valve membrane expands under hydraulic pressure, the guide groove opens to release the liquid; after the pressure is released, the membrane elastically resets, and the groove closes to form a physical barrier), an umbrella-shaped check valve (the eye drops flow forward and push open the umbrella-shaped sealing head; when the flow stops, the sealing head is pressed tightly against the valve seat by back pressure, blocking the backflow path), or a microporous membrane valve (the liquid penetrates the filter membrane under forward pressure; under reverse low pressure, the hydrophobic properties and surface tension work together to seal the micropores, combining anti-backflow and microbial filtration functions). These are all existing technologies and will not be described in detail here.

[0017] This invention relates to a disposable, backflow-proof eye drop bottle, typically used within one day. When using this batch of eye drops, only the eye drops in the corresponding storage chamber 4 are dispensed. Thanks to the isolation provided by the diaphragm 3, the remaining eye drops are not exposed, achieving true single-dose isolation and reducing the risk of infection.

[0018] It should be noted that, under normal circumstances, the needle part 5 is at a certain distance from the corresponding diaphragm 3. When the medicine is dripped by gently pinching the position of the medicine storage chamber 4 of the bottle body 1, the needle part 5 will not come into contact with the diaphragm 3. When the previous diaphragm 3 is squeezed, the next diaphragm 3 will not come into contact with the corresponding needle part 5. Only when the position of the corresponding needle part 5 of the bottle body 1 is squeezed will the diaphragm 3 be punctured by the corresponding needle part 5, ensuring that the diaphragm 3 will not be damaged prematurely.

[0019] In this invention, the diaphragm 3 protrudes upwards and is shaped like an umbrella. Multiple needle-like parts 5 are provided on both sides of the inner wall of the bottle body 1 corresponding to the diaphragm 3. For example, three needle-like parts 5 are provided on each side of the diaphragm 3. The length of the three needle-like parts 5 increases from top to bottom. The number of needle-like parts 5 is large and the needle-like parts 5 are thick enough. When the bottle body 1 is squeezed, the area of ​​the needle-like parts 5 that punctures the diaphragm 3 is large enough to ensure that the holes punctured in the diaphragm 3 can allow the eye drops to flow out smoothly. When the bottle body 1 is inverted and the eye drops are applied, the upwardly protruding diaphragm 3 has a guiding effect to ensure that the eye drops in the medicine storage cavity 4 are discharged and completely drained.

[0020] In this invention, the bottle body 1 and the cap body 2 are made of medical-grade plastic, which is either light-proof or transparent. Specifically, when the eye drops inside the bottle body 1 need to be protected from light, the bottle body 1 and the cap body 2 are made of light-proof plastic, i.e., opaque plastic; when the eye drops inside the bottle body 1 do not need to be protected from light, the bottle body 1 and the cap body 2 can be made of transparent plastic.

[0021] The bottle body 1 has a neck 6 formed at the top, and the cap 2 has a groove with an opening at the bottom. The cap 2 can be closed onto the neck 6 through the groove. The inner wall of the groove and the outer wall of the neck 6 are interference-fitted to achieve a sealed connection. Specifically, the cap 2 and the neck 6 can be connected by snap-fit ​​or thread. When snap-fitting, the snap-fit ​​connection method between the cap and the neck disclosed in CN201320304244.X can be used. When threaded connection, the two must fit tightly to ensure the sealing of the connection. For example, the connection method between the cap and the bottle body of a mineral water bottle is existing technology and will not be described in detail here.

[0022] More preferably, the bottle body 1 is provided with a flexible connecting strip 8. For example, the flexible connecting strip 8 is connected to the bottle body 1 through a collar fitted into the annular groove of the neck 6. The collar can rotate within the annular groove of the neck 6. The end of the flexible connecting strip 8 away from the bottle body 1 is fixedly connected to the cap 2, for example, by adhesive bonding. By providing the flexible connecting strip 8, when opening the cap 2 to dispense medicine, it is not necessary to remove the cap 2 and place it elsewhere. This avoids the cap 2 from being lost and also prevents the cap 2 from rolling to the ground and causing contamination. It should be noted that when opening the cap 2 to dispense medicine, people can bend the flexible connecting strip 8 to move the cap 2 away from the bottle opening without hindering the dispensing process.

[0023] In another preferred embodiment, the bottom of the bottle body 1 has a one-piece molded flat labeling area 7, which can be labeled to disclose product information and make it easier for people to distinguish.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
