Technical Field

The invention relates to a medical appliance, in particular to a dressing prepared by taking a propolis composition as an active ingredient and application in wound treatment.

Background

Trauma is the destruction and damage of human tissues or organs by mechanical factors such as: trauma, burn, bedsore, diabetic foot, and postoperative incision. Wounds not only occur at high rates but also vary widely in degree, and the condition of injury can be severe and complex, even endangering the lives of the injured people.

Not only can the dead or devitalized tissue impede the wound healing process, but the dead tissue or foreign body provides an environment for bacterial growth, increasing the risk of infection and sepsis. On the one hand, the wound should be cleaned in order for the medical staff to correctly assess the wound formed on the tissue and also to be able to see clearly the tissue structure of the wound bed. Debridement, on the other hand, allows the wound to "heal" to an acute state, thereby restarting and accelerating the normal healing process of the wound.

The curette is a common tissue debridement tool in clinic, can thoroughly debride a tissue injury part, and can reduce the degree of secondary injury of the tissue. As a device, the wound cleaning device can only clean dead or inactivated tissues (cell masses) on a wound surface, does not have the effect of promoting tissue healing, and needs to be applied with medicines to promote the healing of the wound surface.

The Zhou Gua disclose a Chinese herbal medicine moistening burn cream (CN1095612A), which can treat various burns and consists of honey, earthworm, and Chinese herbal medicines including pseudo-ginseng, minium, giant knotweed rhizome, bletilla striata, erythrina indica leaves, lysimachia foenum-graecum, musk and camphor, and the proportion of the components is as follows: 78.32-60% of honey, 0.8-1.2% of earthworm, 0.7-1.1% of panax notoginseng, 9-11% of minium, 2-3% of polygonum cuspidatum, 0.9-1.5% of bletilla striata, 8-10% of erythrina indica leaves, 8-9.2% of herba clematidis, 0.08-0.2% of musk, 2.2-2.8% of camphor and the like. The medicine can completely relieve pain within 30 minutes, prevent shock, diminish inflammation, sterilize, resist infection, promote tissue regeneration and hide skin, has no scar after healing I-II degree burn, has no need of skin grafting for III degree burn, and has quick healing, less scar after healing and no various sequelae.

The Chinese patent ZL200810050487.9 discloses an ointment for treating trauma, which can form a layer of protective film on the body surface to isolate and prevent bacteria and viruses from entering from wounds, thereby effectively preventing and controlling infection and achieving the purpose of quick healing. The ointment is prepared from 5 parts of borneol, 150 parts of semen momordicae, 10 parts of calomel, 500 parts of liquid paraffin, 70 parts of white wax, 5 parts of red lead and 200 parts of honey according to the weight ratio. After the ointment is used, the ointment has the characteristics of short treatment course, quick response, obvious treatment effect, complete treatment, no relapse, no toxic or side effect and suitability for clinical popularization. The total effective rate and the cure rate for treating trauma, trauma infection, high fever, edema, local tissue necrosis and complications are 100 percent.

Chinese utility model patent ZL201320706487.6 discloses a honey subsides, still has better viscidity after using 24 hours, and fluid honey can be fine moreover see through isolation rete and wound complex, has promoted the healing of wound. The skin-care wound dressing comprises an elastic PU (polyurethane) base material, a hydrogel matrix layer coated on the base material, a wound-care layer compounded in the center of the hydrogel matrix layer and a lining film, wherein the wound-care layer comprises a honey dry powder layer and an isolation film layer.

It is still another object of the present invention to provide a medical device comprising a propolis composition for application to a wound for promoting healing of the wound.

The invention also aims to provide a dressing containing propolis, which is applied to a wound surface and is beneficial to healing of the wound surface.

The term "organism", "animal" or "patient" as used herein refers to humans, wild animals and Livestock (Livestock). The wild animal is an animal which is not artificially domesticated in a natural state. Livestock are animals that are artificially raised to provide a food source, such as: but are not limited to, dogs, cats, mice, rats, hamsters, pigs, rabbits, cows, buffalos, bulls, sheep, goats, geese, chickens, and the like. The "patient" or "organism" to which treatment is administered is preferably a mammal, particularly a human.

As used herein, "treating" or "treatment" refers to inhibiting, suppressing, reducing, ameliorating, slowing, stopping, delaying or reversing the progression or exacerbation of a disease or condition in order to arrest or reduce the occurrence or progression of the disease, and the various indications of the disease, disorder or pathological condition described as maintaining and/or administering include alleviating or reducing symptoms or complications, or curing or eliminating the disease, disorder or condition.
