Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of local visual hydrogel eye paste.
Background technique
General anesthesia operation patient, head operation patient, prone position operation patient and 1-5 years old pediatric operation patient are performing the operation
In the process, due to the application of arcotic, position is put, the stimulation of thimerosal, all can lead to eye injury, generate eye conjunctivitis,
Keratitis even results in the diseases such as ulcer of the cornea.
Have more research institutions at present and develop hydrogel eye plaster, for protecting eye, macromolecule hydrogel is eye
The phenomenon that wet microenvironment of offer, prevents exposed property eye injury, and such product alleviates exposed property eye injury in clinic, but
There are still certain deficiencies for application in clinic.
Such as number of patent application is a kind of " Self-adhesive moisturizing eye patch " utility model patent of 201120055618.X,
Eye paste described in this patent, can only cover eyeball and the medical pressure sensitive adhesive immobilized gel by two sides is not fallen off.But due to gel
Sticking nature and airtightness it is poor, be detached from eye part skin generate gap, when operation sterilizing area is close to eyes, thimerosal passes through sky
Gap enters eye, stimulates eyes, increases the incidence that ocular complications even infect.
In another example number of patent application is a kind of " the hydrogel eye guarantor of full-closed structure of application number 201220703877.3
Protecting dressing " utility model patent and number of patent application be that 201220703878.8 " a kind of self-adhering type of four layers of interlayer structure is long-acting
Moisturizing eye protection application " eye paste described in utility model patent, it is totally enclosed structure, can is patients with general anesthesia and depth dusk
The eye of fan patient provides safer closed moisturizing environment.But damage blood vessel in long or operation is consumed between during operation to be occurred
Big bleeding, when patient's bleeding amount is big, when general anesthesia is too deep or implements controlled hypotension, when blood pressure must not decline in operation, easily
Retinal hemorrhage occurs.The eye sticker as described in above-mentioned patent completely covers eye, not visible, and doctor can not judge eye in time
Bleeding cannot pointedly take measures, and damage is caused to aggravate.
Summary of the invention
Goal of the invention: to make doctor observe eye bleeding in time in the course of surgery, the present invention provides a kind of offices
The visual hydrogel eye paste in portion can not only provide closed moisturizing environment for the eye of patient with operation, but also can observe eye at any time
The degree of impairment in portion, in order to take remedy measures in time.
Technical solution: to realize the above-mentioned technical purpose, the invention proposes a kind of local visual hydrogel eye pastes, including
Release film, hydrogel layer, nonwoven layer, subsidiary barrier paper handle, adhered layer and bracketing plate.Wherein the hydrogel layer is half
Transparent aquagel, the nonwoven layer are the intermediate bridge layer of hydrogel layer and adhered layer, the design of adhered layer mucilage glue surface both ends
Subsidiary release paper handle, the bracketing layer is bonded with visible area hydrogel, and is contacted with the non-mucilage glue surface of adhered layer, and bracketing is played
Entire product form effect.
Specifically, the hydrogel layer is pasted on the nonwoven layer, then by the nonwoven layer with it is described
Adhered layer is mutually compound, and the nonwoven layer and the adhered layer be in corresponding two oculopupillary position hollow out, and two layers of hollow out
Edge alignment, fretwork area will be enough that two exposings is made to be advisable, and be not more than the surface area of hydrogel layer.Utilize the hydrogel
The transparent characteristic of layer oneself height, forms a visual windows.
The beneficial effects of the utility model are: observing eyes of patients at any time by visual windows convenient for doctor in operation and becoming
Change situation, while a good totally enclosed micro- wet environment can be provided again for eye.
Based on the above technical solution, the utility model can also do following improvement.
Further, the compound stickup in the upper surface of nonwoven layer and the lower surface of hydrogel layer, lateral the two of non-woven cloth
It holds the arc along non-woven cloth outer ring edge to extend, forms handle, the long 1 ~ 30mm of handle.
Taking the beneficial effect of above-mentioned further scheme is: the hydrogel layer, the first and compound stickup of nonwoven layer, then
It is connected by nonwoven layer with adhered layer, it is possible to increase the stability of connection.The handle of the non-woven cloth transverse ends is side
Just production operation, and the area that non-woven cloth is connected with adhered layer can be increased, increase the stability of connection.
Further, the adhered layer shape meets ergonomics, and vertically following edge is more following than hydrogel layer for adhered layer
Edge goes out greatly 5 ~ 20mm, and vertical top edge goes out greatly 0 ~ 5mm than hydrogel top edge.
Taking the beneficial effect of above-mentioned further scheme is: the adhered layer shape meets ergonomic, and adhered layer table
Area is greater than the nonwoven layer and hydrogel layer surface area.It can make local visual medical hydrogel eye mask and the close patch of face
It closes, forms closed wet microenvironment.Vertically following edge can make the adhered layer than hydrogel layer lower edge greatly out 5 ~ 20mm
Adhered layer and skin close adhesion, prevent thimerosal from penetrating into.The vertical top edge of adhered layer goes out greatly 0 ~ 5mm than hydrogel top edge,
It can avoid adhered layer and eyebrow adhesion when local visual medical hydrogel eye mask is removed from face.
Further, adhered layer mucilage glue surface both ends and subsidiary barrier paper handle bonding.
Taking the beneficial effect of above-mentioned further scheme is: avoid user and the glue surface of the adhered layer from contacting, it is convenient
Operation.
Further, the release film layer lower surface and hydrogel layer upper surface, which are applied, closes, the nonwoven layer upper surface with
The bonding of hydrogel layer lower surface, adhered layer upper surface inner circumferential and non-woven cloth lower surface bond, and release film surface area is greater than
Paste surface layer.
Taking the beneficial effect of above-mentioned further scheme is: release film layer passes through hydrogel layer and nonwoven layer and stickup
Layer is connected, viscous with outer packaging prevented also from pasting to protect hydrogel layer, nonwoven layer and adhered layer not contaminated
Even.
Further, bracketing layer upper surface and adhered layer lower surface, which are applied, closes, and bracketing surface layer is identical as release film layer,
There are enabling capabilities with a thickness of 0 .1~2mm using any one in PET, PVC, PP.
Taking the beneficial effect of above-mentioned further scheme is: facilitate operator by local visual medical aquogel eye paste from
It is taken out in packaging, and protects eye sticker indeformable during transportation.
Preferably, packaging of aluminium foil bag is used after the local visual medical aquogel eye paste molding, and with sterile production
Product provide, and the local visual medical aquogel eye paste packed need to carry out sterilization treatment, ensure that the safety of product.
The size of the utility model local visual medical aquogel eye paste can be adjusted according to actual needs.
