Abstract
The utility mode discloses a medical bioactive dressing patch, comprising a breathing elastic and sticky fabric layer on whose top is provided with a water-absorptive layer and again on whose top is provided with a chitosan non-weaving layer on which low-molecular chitosan or collagen medicine is applied. The sizes of the water-absorptive layer and the chitosan non-weaving layer the same but lengthwise shorter than the elastic and sticky layer. An isolation paper layer with its central part laid on the top of the chitosan non-weaving layer and its both edges are stuck to the elastic and sticky layer is laid on the chitosan non-weaving layer. The utility model takes the chitosan non-weaving layer as a medicine carrier and sprays the low-molecular chitosan or collagen on the chitosan non-weaving layer, thereby widely applicable to healings of operation, injury, wound and wound infection due to good antibacterial effect and air permeability.
Description
Technical field
This utility model relates to a kind of medical and hygiene article, is the active dressing of a kind of medical bio specifically.
Background technology
Medical dressing typically refers to the disposable medical hygienic article, and it comprises aseptic gauze, styptic cotton and adhesive bandage etc., is used for wound surface is covered, wraps up, and prevents that wound infection from suppurating.Existing medical dressing product great majority belong to sterilization level product, are lamellar or composite bed product, and these products consumption in medical industry is very big, but also has some defectives, and wherein topmost problem is that antibacterial functions is poor.Occurred some on the market yet and had medical bio dressing antibiotic, bacteria resistance function, but to improving the function of wound and peripheral human body, the healing of accelerating wound does not then relate to, therefore, function singleness.As the nursing of infant umbilical cord, also need certain nursing medicinal liquid to be used, just can reach the optimal care effect.
Summary of the invention
The technical problems to be solved in the utility model provides the active dressing of medical bio of a kind of functional diversities, good anti-bacterial effect.
For solving the problems of the technologies described above, this utility model comprises the elastic fabric adhered layer of breathability, be attached with the suction bed course on the adhered layer, its construction features is to be attached with the chitosan nonwoven layer on the suction bed course, spray is with low molecular chitosan or collagen protein medicine on the chitosan nonwoven layer, suction bed course and chitosan nonwoven layer length, width is identical and in the longitudinal direction less than the length of elastic fabric adhered layer, on the chitosan nonwoven layer, be covered with separator paper layer, the separator paper layer mid portion cover described polysaccharide nonwoven layer above, both sides and elastic fabric adhered layer are adhesively fixed.
As to improvement of the present utility model, described suction bed course and chitosan nonwoven layer on width less than the width of elastic fabric adhered layer, the separator paper layer mid portion cover described polysaccharide nonwoven layer above, its periphery is adhesively fixed with the elastic fabric adhered layer.
As to further improvement of the utility model, described separator paper layer is divided into two symmetrically, overlaps in its vertical or horizontal middle part.
After adopting said structure, this utility model with the chitosan nonwoven layer as pharmaceutical carrier, and spray attached low molecular chitosan or collagen protein thereon, so its good anti-bacterial effect, the while good permeability, be applicable to the healing of wounds such as operation, wound and other traumatic infection, diverse in function, applied widely.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the reference diagram of this utility model user mode.
The specific embodiment
The active dressing of medical bio shown in Figure 1, the elastic fabric adhered layer 1 that comprises breathability, be attached with suction bed course 2 on the adhered layer 1, on suction bed course 2, be attached with chitosan nonwoven layer 3, spray is with low molecular chitosan or collagen protein medicine or other functional medicine on the chitosan nonwoven layer 3, as calcium alginate, suction bed course 2 and chitosan nonwoven layer 3 length, width is identical and in the longitudinal direction less than the length of elastic fabric adhered layer 1, on chitosan nonwoven layer 3, be covered with separator paper layer 4, separator paper layer 4 mid portions cover described polysaccharide nonwoven layer 3 above, both sides and elastic fabric adhered layer 1 are adhesively fixed.Perhaps described suction bed course 2 and chitosan nonwoven layer 3 on width less than the width of elastic fabric adhered layer 1, separator paper layer 4 mid portions cover described polysaccharide nonwoven layer 3 above, its periphery is adhesively fixed with elastic fabric adhered layer 1.And separator paper layer 4 can be divided into two symmetrically, overlaps in its vertical or horizontal middle part.
Figure 2 shows that when the active dressing of this medical bio is used for the nursing of infant umbilical cord, use for convenient, the active dressing of this medical bio is folded into strip and block 8, put into packing box 6, also be placed with the cotton rod 7 of bottled conditioning liquid 9 and medical disinfecting in this packing box 6 simultaneously, complete sale is convenient to change the active dressing of medical bio and is applied medicinal liquid to umbilical cord portion in the nursing process of infant umbilical cord.
