Problems solved by technology

However, the traditional Band-Aid itself has some shortcomings that cannot be ignored: when the Band-Aid is applied to the skin wound, because of its poor air permeability, when the application time is long, the moisture evaporation of the wound skin will be affected, thereby affecting the normal respiratory function of the skin and Physiological function weakens the surface cell regeneration ability of the wound skin and prolongs the wound healing time (Liu Tangxia, Disadvantages of long-term application of band-aids on wounds, Qilu Nursing Magazine, 1996, 2 (4): 24); also because it is not easy to breathe, If used in hot seasons, it is easy to have ulceration and pus. If the use is not stopped in time, the infection will be aggravated (Chen Yumin, Band-aid is not a panacea, Changshou, 1996, August, 21.)
But it ignores the advantages of traditional Chinese medicine powder medicine in the treatment of external trauma, which is not conducive to the healing of wound surface

An adhesive bandage with powder medicine packed by instant film is composed of a substrate, the staltic and wound treating powder medicine, and the instant film made of non-toxic high-molecular material or the natural high-molecular material extracted from Chinese-medicinal materials, such as bletilla gum, aloe gel, aloe polyose, konjak gel, konjak polyose, etc.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a pharmaceutical preparation in the form of a patch. Background technique [0002] Traditional Chinese medicines for knife wounds are powders, such as the famous Yunnan Baiyao. The use of powder to treat knife wounds and small wounds in daily life has great advantages. After thousands of years of clinical verification, Chinese medicine powder has a rapid hemostatic effect; It coagulates, ruptures and releases blood coagulation factors for the core, and quickly achieves the effect of hemostasis. The powder trauma medicine powder has the advantages of ventilation, stopping exudation and accelerating wound healing when used in wounds. [0003] However, the use of powder medicine also has certain inconveniences. For example, when the patient uses it, it is difficult to control the medicine each time, and it does not meet the quantitative requirements; it is extremely incon...
