Preparation process of pain-relieving and stasis-removing hydrogel patch

Abstract

The invention discloses a preparation process of a pain-relieving and stasis-removing hydrogel patch, which comprises the following steps: step 1, uniformly mixing powdery medicinal raw materials to obtain mixed powder; 2, carrying out alcohol extraction treatment on the mixed powder to obtain a mixed extracting solution; step 3, carrying out concentration treatment on the mixed extracting solution to obtain a concentrated solution; 4, uniformly mixing the concentrated solution with hydrogel to obtain mixed hydrogel; and 5, uniformly smearing the mixed hydrogel on the patch, pasting glass paper on the mixed hydrogel, and cutting themixed hydrogel into pieces to obtain a finished product. In the first step, the powdery medicinal raw materials comprise the following components in parts by weight: 95-105 parts of curcuma zedoary; 98-110 parts of turmeric; 95-105 parts of cortex phellodendri; 48-52 parts of frankincense; 45-55 parts of myrrh; 110-130 parts of radix angelicae dahuricae; 95-105 parts of garden balsam seed; 98-102 parts of semen momordicae; and 95-105 parts of muskroot-like semiaquilegia root. The preparation process has the advantages of being capable of improving use comfort and improving the treatment effect.

Description

technical field [0001] The invention relates to an analgesic and blood stasis patch, in particular to a preparation process of an analgesic and stagnation-dispelling hydrogel patch. Background technique [0002] When the human body is subjected to external violent impact, it may cause injury, swelling and pain of the limbs. For traumatic swelling and pain, the main treatment method is to promote blood circulation, remove blood stasis, reduce swelling and relieve pain. There are two main types of medicines for treatment: internal medicine and external plaster. At present, externally applied plasters are mainly rubber-type plasters, which have poor compatibility with the skin, general air permeability, prone to skin allergies, and poor comfort in use; moreover, rubber-type plasters have lower drug loading ( Less than 2%), resulting in unsatisfactory treatment effect and longer treatment cycle. Therefore, the existing technology has the problems of poor user comfort and unsa...
