Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in detail.
As shown in Figures 1 to 4, the utility model provides a kind of medical hydrogel dressings with Improvement type protective film layer,
With two bottom off-style paper layers 400 and the temporary hydrogel layer 300 sticked of two bottom off-style paper layer 400, have one
Pressure sensing adhesive layer (not being painted) and (pressure sensing adhesive layer is present in ventilative the ventilative film layer 200 being attached on the hydrogel layer 300
The underface of film layer 200), and with the temporary protective film layer 100 sticked of the ventilative film layer 200.
The approximate polygon of the external form of ventilative film layer 200 is one square of approximation in the utility model embodiment.It is described
Four angles all roundings of square form rounding angle 210, this is to be avoided being attached on people by pressure sensing adhesive layer when ventilative film layer 200
When body skin, excessively sharp part meeting stress is concentrated and is removed, and medical hydrogel dressings is caused gradually to fall off.It is practical new at this
In type embodiment, polygon above-mentioned is square.In practical operation, designs, can be taken not according to different wound sites
Same shape, such as triangle, rectangle, pentagon or hexagon.The utility model does not limit the shape of polygon.At this
In utility model embodiment, film layer 200 of breathing freely is as made by polyurethane.For alternative, thermoplastic polyurethane gathers
Tetrafluoroethene or polyethylene are also the material that can choose.The pressure-sensing glue that pressure sensing adhesive layer uses, material are generally divided into rubber, pressure gram
Power, silica gel and tetra- kinds of PU.Using upper not restricted.However in order to cooperate ventilative film layer 200 to ventilative and fire resistance characteristic
It is required that acryl or the material of PU is preferred in pressure-sensing glue.
The function of protective film layer 100 is that temporary protection is breathed freely film layer 200, is avoided using being preceding scraped off or tear to pieces, protective film
The external form of layer 100 is similar to the polygon at the tool rounding angle.Preferably each side can trim, to reduce material loss.It is practical at this
In embodiment, the material of protective film layer 100 is polyethylene terephthalate.In the streets certain suitable materials, such as orientation are poly-
Made by propylene or polyethylene, the material of protective film layer 100 can also be become.If for the sake of simple designs, protective film layer 100
Release paper can be used.One jiao of protective film layer 100 has a protrusion 110, as shown in Figure 1.Protrusion 110 is for conveniently tearing off
The protective film layer 100 is used, and in practical application, protrusion 110 can have multiple exist simultaneously in polygon with more than one
On each angle.
There is special design in the protrusion 110, as shown in Figure 2.The external form of the protrusion 110 has a line of symmetry 113,
The line of symmetry 113 and the polygonal line of the two sides of protrusion 110 form two angles, that is, with a left side sideline 111 and line of symmetry
113 one θ of folder1Angle, a right side sideline 112 press from both sides a θ with line of symmetry 1132Angle, two included angle are rough equal.Such design
There are several benefits.Firstly, connection is drawn in protrusion 110 when user removes protective film layer 100 with protrusion 110 (as shown in Figure 3)
100 part of protective film layer, the force of the left and right sides is uniform.The stress of certain side can will not be caused excessive in this way, held
Easily by 200 pull-up of film layer ventilative under it.Further, since user exerts a force, the direction drawn is not perpendicular to each of protective film layer 100
Side, protective film layer 100 can be torn off along an angle δ with ventilative film layer 200.Test is pointed out, when the angle δ is 0 degree, is easiest to make
Skin is removed at protective film layer 100.
In other embodiments, protrusion 110 on can be painted with a sign 114, as shown in Figure 4.Sign
114 guide users indicate that direction removes protective film layer 100 along it.Instruction direction above-mentioned should be in reverse in ventilative film layer 200
With the immediate rounding angle in protrusion 110 (as shown in figure 3, position where being in reverse to rounding angle 210).In this way, more can be
Hydrogel patch causes ventilative film layer 200 to be pulled up in use, user is allowed to avoid force direction mistake.
Hydrogel layer 300 can be as prepared by the substrate for combining hydrogel, and the utility model does not limit it and is made
Method, material and shape and size.It should be noted that the characteristic of hydrogel layer 300 wants that the sepage of human skin wound can be absorbed,
Wound moist is maintained, while completely cutting off external contamination source.The material of bottom off-style paper layer 400 does not limit, and general market can be bought
Release paper, may serve to combine, to form the off-style paper layer 400.Off-style paper layer 400 is in addition to temporary with hydrogel layer 300
When property stick it is outer, also with the pressure sensing adhesive layer of ventilative 200 section below of film layer is temporary sticks.Other than protecting hydrogel layer 300,
Also protection future will stick pressure sensing adhesive layer on human skin, encroach on from dust, reduce stickiness.Although as shown in Figure 3
Bottom off-style paper layer 400 has two panels, but its quantity is not limited to 2.As long as production can be removed effectively and be facilitated, single
Bottom off-style paper layer 400 more than bottom off-style paper layer 400 or more than two, also in the covering scope of the utility model.
The utility model has the advantage that
A kind of medical hydrogel dressings with Improvement type protective film layer of the utility model, can solve aerogel dressing and exist
When removing protective film layer in ventilative film layer, the problem of partially ventilative film layer is pulled away from skin surface is caused.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.
