Abstract

The utility model discloses a medical aquogel wound dressing, which contains an aquogel layer, wherein a poly urethane (PU) layer is arranged on the upper part of the aquogel layer; a polyester (PET) layer is arranged on the upper part of the PU layer; a glassine paper layer is arranged on the lower part of the aquogel layer; a pressure-sensitive adhesive is arranged between the aquogel layer and the PU layer; and a pressure-sensitive adhesive is arranged between the aquogel layer and the glassine paper layer. According to the medical aquogel wound dressing, the medical PU film layer which is high in air permeability and transparency is covered on the aquogel layer, so that foreign bacteria invade into the aquogel layer difficultly when the wound dressing is used; and high elasticity and toughness of the PU film layer are just matched with the property of aquogel, so that the strength of the aquogel is enhanced, and the aquogel wound dressing is not easy to damage when used. In addition, the PET layer with a good mechanical property is covered outside the PU film layer, so that a PU film is not easy to crimp and wrinkle when the aquogel wound dressing is used, and the aquogel wound dressing is convenient to operate.

Description

Medical hydrogel wound dressing

Technical field

This utility model relates to a kind of medical nursing material of moist wound, or rather, is a kind of medical hydrogel wound dressing.

Background technology

Development of science and technology makes people improve constantly the requirement of medical dressing, easy breed bacteria such as traditional dressing such as gauze, Cotton Gossypii etc., and wound fluid is prone to form crust with dry corium; Hinder epithelization; Wound surface is prone to and the dressing adhesion simultaneously, and changing dressings causes pain when uncovering, bring the secondary wound.

The medical aquogel compounded dressing for wound also has good imbibition, protects the wet thoroughly and separated bacterium function of liquid except having excellent biological compatibility, has kept suitable wound miniclimate to wound like this, prevents incrustation, is beneficial to the healing of wound surface.The dressing of this type not with the wound adhesion, no allergy and toxic and side effects, easy and simple to handle when changing dressings, do not have any material and remain in the wound.And existing more most of hydrogel wound dressing; All be directly to adopt hydrogel layer; Do not have the protection of other layer, so extraneous antibacterial directly corrodes hydrogel layer easily, thereby pollutes; Hydrogel layer does not have protective layer outward in addition, so causes the too fast of the water content of hydrogel layer own to be lost easily yet; Also has a kind of hydrogel wound dressing; It pastes one deck on the protection backing be the hydrogel of skeleton with fabric or non-woven fabrics, though the hydrogel of this type has solved hydrogel, and the problem of intensity; But be cost but with the transparency of sacrificing self; Transparency is bad, and the healing state of wound just is not easy to observe, and can not intercept extraneous antibacterial.

The utility model content

This utility model mainly is to solve the existing in prior technology technical problem, thereby provides a kind of transparency high and high-intensity medical hydrogel wound dressing.

The above-mentioned technical problem of this utility model mainly is able to solve through following technical proposals:

A kind of medical hydrogel wound dressing comprises hydrogel layer, and the top of described hydrogel layer is provided with a PU layer, and the top of described PU layer is provided with a pet layer, and the bottom of described hydrogel layer is provided with a lattice Racine ply of paper.

As the preferred embodiment of this utility model, described lattice Racine ply of paper comprises takes off mouth.

As the preferred embodiment of this utility model, be provided with pressure sensitive adhesive between described hydrogel layer and the said PU layer.

As the preferred embodiment of this utility model, be provided with pressure sensitive adhesive between the ply of paper of described hydrogel layer dative Racine.

Preferred embodiment as this utility model; The thickness of described pet layer is 0.03～0.06 millimeter; The thickness of described PU layer is 0.025～0.04 millimeter; The thickness of described pressure sensitive adhesive is 0.02～0.04 millimeter, and the thickness of described hydrogel layer is 2～5 millimeters, and the thickness of described lattice Racine ply of paper is 0.07～0.14 millimeter.

The medical hydrogel wound dressing of this utility model on hydrogel layer, cover breathability better, the also medical preferably PU thin layer of the transparency; Extraneous in use antibacterial just is difficult for invading; The PU thin layer also has preferably, and elasticity and toughness just in time are complementary with the character of hydrogel own; Strengthen the intensity of hydrogel, made this hydrogel wound dressing not fragile in use.In addition, be covered with mechanical property pet layer preferably again, make that the PU film was difficult for crimping, wrinkling when this hydrogel wound dressing used in the outside of PU thin layer, more convenient during operation.

Description of drawings

In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of this utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of first kind of embodiment of the medical hydrogel wound dressing of this utility model;

Fig. 2 is the structural representation of second kind of embodiment of the medical hydrogel wound dressing of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of this utility model is set forth in detail, thereby the protection domain of this utility model is made more explicit defining so that advantage of this utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

This utility model provides a kind of transparency high and high-intensity medical hydrogel wound dressing.

As depicted in figs. 1 and 2, a kind of medical hydrogel wound dressing comprises hydrogel layer 3, and the top of this hydrogel layer 3 is provided with a PU layer 2, and the top of this PU layer 2 is provided with a pet layer 1, and the bottom of this hydrogel layer 3 is provided with a lattice Racine ply of paper 4.This Ge Laxin ply of paper 4 comprises takes off mouth 41.

Be provided with pressure sensitive adhesive between this hydrogel layer 3 and this PU layer 2.Be provided with pressure sensitive adhesive between these hydrogel layer 3 dative Racine ply of papers 4.The thickness of this pet layer 1 is 0.03～0.06 millimeter, and the thickness of this PU layer 2 is 0.025～0.04 millimeter, and the thickness of this pressure sensitive adhesive is 0.02～0.04 millimeter, and the thickness of this hydrogel layer 3 is 2～5 millimeters, and the thickness of this Ge Laxin ply of paper 4 is 0.07～0.14 millimeter.

Wherein, hydrogel layer is mainly processed by polyvinyl alcohol (PVA), agar powder and carrageenan.This PU layer is the gas permeable polymers thin film, and this pet layer is a polyphenyl dioctyl phthalate glycol ester, and this material has the good mechanical performance, and nontoxic, tasteless, and wholesomeness is good.

The mentality of designing of this utility model below only is described with an embodiment, and under the situation that system allows, this utility model can expand to external more function module simultaneously, thereby expands its function to greatest extent.
