Description
Technical field
The utility model belongs to technical field of medical equipment, is related to a kind of eyedrop spray device.
Background technology
With the change of people's quality of life, due to the increase of study and work pressure, the people with eye illness is more and more,
Particularly young man also more and more uses contact lenses, easily produces eye illness, eye fatigue and the dry and astringent symptom of eyes, one
As people's first choice be exactly dripping eyedrop and spongaion to recuperate, but for old man and child, once suffer from eye diseases, using putting drops in one's eyes
The mode of water is too inconvenient or mismatches.
At present, during dripping eyedrop, first have to that neck is swung back as possible, then make the eyes that liquid medicine bottle alignment is opened wide by liquid medicine
Drop by drop instill intraocular so that operation is very inconvenient, and people typically can produce during dripping eyedrop
Raw eye blink response, if operation is not skilled enough, can usually be such that eyedrops majority has all dripped to outside eye, both cause waste, made again
Patient is obtained to feel very ill.
For above-mentioned defect, people have developed various eyedrops bottles：
Such as Chinese patent application (application number：201220607846.8) disclose a kind of spraying type eyedrops bottle, including bottle
Body and the gland provided with nozzle, by pressing gland, can be sprayed the liquid medicine in bottle by nozzle, bottle is on before nozzle
The setting of side is provided with eye support, and the front end face of eye support is the arc concaved, and eye support is fixed on the neck part of bottle by support.
Although said structure takes the mode of spray eye liquid medicine so that eyedrops can be injected into eyes, but still suffer from deficiency：
The spraying type eyedrops bottle is only that eye support is provided with front of nozzle, but is due to that eyedrops is to be injected into intraocular, and then
So that being only to set eye support, do not ensure that eyedrops can all be injected into intraocular, cause the waste of eyedrops, while making yet
Obtaining user needs repeatedly to carry out the process of injection eyedrops so that user feels very ill.
The content of the invention
The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that a kind of eyedrop spray device,
How technical problem to be solved in the utility model is so that the eyedrops that eyedrop spray device sprays can all enter eye
The uniform no pressure of interior and spray atomization is not dazzling.
The purpose of this utility model can be realized by following technical proposal：
A kind of eyedrop spray device, includes the bottle of sprayable eyedrops, it is characterised in that be arranged with eye on the bottle
Cover stent, the eyeshade support includes connection ring, connecting rod and the Eye path structure being hinged in connecting rod, the connection ring and bottle
