Problems solved by technology

The dressing uses traditional Chinese medicine ingredients to create a moist and sterile local environment for the wound, and has anti-infection effects. The above patents are still different from the original Chinese medicine ointment preparation method. It is only used for traditional treatment of burns and scalds. The healing effect is general, and Unable to prevent the adhesion of the wound site, there is a greasy feeling

Embodiment 1

[0032] The high-molecular polymer dressing of this embodiment includes a base cloth coated with viscose and a dressing, and a release paper covered on the viscose and the dressing, and the dressing is formed by mixing the following active ingredients by mass percentage:

[0033]Burnet Extract 25%

[0034] Knotweed Extract 24%

[0035] Chitin 22%

[0036] D-Glucopyranoside 17%

[0037] Mannan 12%.

[0038] Among them, the main components of the Burnet extract include Burnet glycoside I, Burnet glycoside II, Burnet A, Burnet B, and Burnet E extracted from the rhizome of Burnet eucalyptus. The aglycone of Burnet glucoside and Burnet glucoside is ursolic acid. The hydrolysis of Burnet glucoside Ⅰ and Burnet glycoside Ⅱ produces pampoulic acid and arabinose, etc. The composition of Burnet extract also includes vitamin C extracted from Burnet leaves, and cyanidin and procyanidin from Burnet flowers.

[0039] The main components of Polygonum cuspidatum extract include emodin, e...

Embodiment 2

[0090] The rest of the high molecular polymer dressing of the present embodiment is the same as that of Embodiment 1, except that:

[0091] The dressing is prepared by mixing the following active ingredients in mass percentage:

[0092] Burnet Extract 28%

[0093] Knotweed Extract 23%

[0094] Chitin 21%

[0095] D-Glucopyranoside 18%

[0096] Mannan 10%.

[0097] The preparation method of the polymer dressing of this embodiment is the same as that of Embodiment 1.

[0098] Adopt the method identical with embodiment one to carry out infectious wound healing test to the high molecular polymer dressing of the present embodiment, test result is as follows:

[0099] 1) Patient conditions: A total of 45 patients with infected wounds were observed. The test group covered 25 cases of high molecular polymer dressings of this embodiment, and the control group covered 20 cases of ordinary sterile wound plasters.

[0100] 2) Bacteriological conditions: 12 out of 25 cases in the tes...

Embodiment 3

[0107] The rest of the high molecular polymer dressing of the present embodiment is the same as that of Embodiment 1, except that:

[0108] The dressing is prepared by mixing the following active ingredients in mass percentage:

[0109] Burnet Extract 30%

[0110] Knotweed Extract 26%

[0111] Chitin 18%

[0112] D-Glucopyranoside 12%

[0113] Mannan 14%.

[0114] The present invention is not limited to the specific technical solutions described in the above embodiments, and all technical solutions formed by equivalent replacement are within the scope of protection required by the present invention.

[0115] The preparation method of the polymer dressing of this embodiment is the same as that of Embodiment 1.

[0116] Adopt the method identical with embodiment one to carry out infectious wound healing test to the high molecular polymer dressing of the present embodiment, test result is as follows:

[0117] 1) Patient conditions: A total of 48 patients with infected wound...

Abstract

The invention relates to a polymer dressing and dressing patch. The dressing patch comprises a base cloth on which glue and the dressing are coated and release paper covering the glue and dressing. The dressing is prepared by mixing the following active ingredients by weight percent: 24-30% of sanguisorba officinalis root extracts, 20-27% of polygonum cuspidatum extracts, 18-25% of chitin, 12-18% of D-glucopyranoside and 10-15% of mannan. The dressing and the dressing patch can stop bleeding quickly, prevent infections, promote wound healing, reduce pains of patients, shorten the rehabilitative periods of patients and avoid pathogen harms and nerve fiber lesions.

Description

technical field [0001] The invention relates to a dressing and a dressing patch for human body wounds, belonging to the technical field of medical preparations. Background technique [0002] Wound repair has always been one of the most important and basic issues faced by trauma (burn) surgery and even the entire medical field. The hemostatic gauze, hemostatic fiber, and hemostatic bandage commonly used in clinic have their limitations in use; they have a single function, take a long time to stop bleeding, are easy to adhere to the wound and are difficult to change dressings, and are powerless to symptoms such as wound infection and suppuration. There are many shortcomings such as isolation and protection of various skin wounds, and failure to promote wound healing. [0003] With the continuous advancement of medical technology, traditional dressings that can only simply cover wounds have been replaced by active dressings that have multiple functions such as hemostasis, infe...
