Description

Eye drop bottle with backflow prevention effect

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to eye drop bottle with prevent effect of backflowing.

Background

The eye is the most important information receiving organ of human beings, and the eye is a very fragile organ at the same time, and the visual maintenance is more and more emphasized by people. The eye drops are a sterile liquid preparation for eyes which is used more clinically, and because of the particularity of the application part of the eye drops, higher requirements are put on the quality and the safety of the eye drops, and even the eye drops gradually develop towards the direction of injection, so that the sterile effect is required to be achieved. Most of the current eye drops exist in a multi-dose form in an eye drop bottle, and are dripped out from a liquid outlet of the eye drop bottle and then enter eyes.

The eye drop bottle design on the market at present is mostly very simple, is the passageway of cylinder type mostly, and the problem that appears when using this kind of eye drop bottle mainly has: 1. the eye drop bottle without the anti-backflow design has the advantages that when the bottle mouth is in contact with skin and polluted, the backflow liquid medicine can bring impurities and bacteria into the bottle, so that the liquid medicine is polluted and carries bacteria in a short time, and the quality of the residual eye drops is influenced; 2. when the medicine liquid is used, the medicine liquid is dripped in a dripping form, and several drops of liquid can be dripped together when the medicine liquid is pressed forcibly, so that the clinical use amount cannot be controlled, and even the liquid can be ejected in a linear manner; when the user is pressed lightly, the user can flow less liquid medicine, and even one eye drop can not be generated after squeezing for half a day. Based on this, there is a need for an anti-reflux eye drop bottle, which can control the flow rate of the dropping liquid and prevent the reflux liquid from entering the bottle body to contaminate the eye drop.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims to solve the technical problem of overcoming the defect of easy pollution caused by liquid medicine backflow in the prior art, thereby providing the eye drop bottle with the backflow prevention effect.

The above technical purpose of the present invention can be achieved by the following technical solutions:
