Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, the above terms should not be construed as limiting the present invention.

As shown in fig. 1-2, the waterproof band-aid comprises a body 1, a wound pad 2 located at the center of the body 1 and a protective film 3 for covering the back of the body 1, wherein the protective film 3 is made of a material commonly used in the art and is used for protecting hydrogel and the wound pad 2 on the body 1, the protective film 3 is bonded with the back of the body 1 through the hydrogel, and the protective film 3 can be in the form of one sheet or two sheets, which is consistent with the prior art.

Specifically, the body 1 is made of a PU film, and the back of the body 1 is provided with hydrogel, wherein the PU film has good elasticity and high lightness. Although the thickness is extremely thin (0.012-0.035mm) in terms of waterproofness, the physical performance (the bearable water pressure is more than 10000mm water column) which cannot be compared with other materials is realized by introducing a hydrophilic agent into the materials by using a high-tech technology, so that the film has high waterproofness and excellent moisture permeability (sweat of a human body can freely penetrate among the films). The breakthrough in function is matched with the laminating processing technology of the textile industry, the added value of the textile is greatly improved, the air permeability of the main body 1 of the application is also obviously improved, therefore, the air-permeable sole can play an excellent role in air permeability without punching the body 1, and can also obviously reduce the thickness of the body 1, the hydrogel in the embodiment adopts the hydrogel prepared by the preparation method disclosed in the Chinese patent CN110358130B, the hydrogel prepared by the method can generate self-hydrophobic effect under water to expel water molecules, hydrophobic interaction is generated with the substrate, so that the adhesive substrate can be quickly, repeatedly and stably adhered to various adhesive surfaces under underwater conditions without additional chemical modification, therefore, the body 1 can be repeatedly attached to the attached position even if it is not attached, and has an advantage of good waterproof property and excellent adhesion property in water.

In other embodiments, the body 1 can also be made of TPU film, which also has waterproof and breathable effects.

Therefore, the body 1 made of the structure and the material has the waterproof performance and the adhesive effect which are incomparable with those of the similar PU film wound coverings.

Specifically, wound pad 2 is made through ventilative cotton pad, has soaked the antiseptic solution in this cotton pad, still has soaked wound healing liquid medicine in wound pad 2, and wherein the wound healing liquid medicine is the common product of medical technical field, suppresses bacterial growing through the antiseptic solution, improves wound healing speed through the wound healing liquid medicine, helps the wound to heal fast.

In this embodiment, the length of the main body 1 is 9cm, the width is 3cm, the thickness of the wound pad 2 is 1mm, and the thickness of the main body 1 is 0.05-0.5 mm, which may be 0.1m, 0.2mm, 0.3mm, etc.

Referring to fig. 1 and 3, in order to be suitable for more use scenarios, the left and right ends of the main body 1 are respectively provided with a folding section 5, the folding section 5 includes a first section 51 close to the wound pad 2 and a second section 52 covering the first section 51 when folded, neither the second section 52 nor the second section 52 is provided with hydrogel, the main body 1 can be extended or shortened through the folding section 5, that is, the main body 1 is folded when a shorter main body 1 is needed, and the main body 1 is unfolded when a longer main body 1 is needed, so that the folding adhesive bandage is suitable for more use scenarios, only the folded main body 1 needs to be designed to be one to two centimeters shorter than the existing adhesive bandage, and the unfolded main body 1 is designed to be about one centimeter longer than the existing adhesive bandage. Therefore, the length of the main body 1 is 12cm after unfolding, and is 9cm after folding.

If the width of the body 1 is not satisfactory, the body 1 can be cut by the indication of the cutting guide dotted line 4, so that the cut body 1 can still be normally used without causing the damage or the abnormal use of the internal wound pad 2, wherein the cutting guide dotted line 4 is arranged at the two ends of the body 1 in the width direction.

Compared with the prior art, this application still used aquogel when using the PU film, consequently not only has the ultra-thin ventilative waterproof advantage that adds of PU film, possess the advantage that aquogel waterproof performance is good moreover, can not drop when bathing, and the wound pad 2 of making through ventilative cotton pad can protect the wound effectively, utilizes the antiseptic solution to carry out the disinfection operation, plays the effect of supplementary disinfection, helps the wound to heal fast, and protection film 3 is conventional product for the viscidity of protection aquogel.

The present invention is not described in detail in the prior art, and therefore, the present invention is not described in detail.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Although the terms body 1, wound pad 2, protective film 3, cutting guide dashed line 4, fold section 5, first section 51, second section 52, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
