Embodiment 1

[0063] A spray film of dragon's blood, made of the following raw materials in parts by weight: 2.5% of dragon's blood, 4% of polyvinylpyrrolidone-K30 (PVP-K30), 0.1% of ethyl cellulose (EC), 8% of propylene glycol %, the balance is ethanol.

[0064] Described ethanol is the ethanol that volume concentration is 85%.

[0065] The preparation method of the dragon's blood spray film comprises the following steps:

[0066] (1) Dragon blood jerky is dissolved in ethanol with a volume concentration of 85%, and made into liquid A for later use;

[0067] (2) Dissolve PVPK30 and EC in ethanol with a volume concentration of 85% to make liquid B for later use;

[0068] (3) Keep liquid A at 60°C for heat preservation, add liquid B and propylene glycol while stirring, continue to stir for 30 minutes, take it out and let it stand overnight, filter, add ethanol with a volume concentration of 85% to the full amount, and the product is ready.

Embodiment 2

[0070] A spray film of dragon's blood, made of the following raw materials in parts by weight: 2.5% of dragon's blood, 5% of polyvinylpyrrolidone-K30 (PVP-K30), 0.3% of ethyl cellulose (EC), 7.5% of propylene glycol %, the balance is ethanol.

[0071] The ethanol is 80% ethanol by volume.

[0072] The preparation method of the dragon's blood spray film comprises the following steps:

[0073] (1) Dragon’s blood was dissolved in ethanol with a volume concentration of 80% to make liquid A for later use;

[0074] (2) Dissolve PVPK30 and EC in ethanol with a volume concentration of 80% to make liquid B for later use;

[0075] (3) Keep liquid A at 60°C for heat preservation, slowly add liquid B and propylene glycol while stirring, continue to stir for 40 minutes, take it out and let it stand for 12 hours, filter, add ethanol with a volume concentration of 80%, and the product is ready.

Embodiment 3

[0077] A spray film of dragon's blood, made of the following raw materials in parts by weight: 2.5% of dragon's blood, 6% of polyvinylpyrrolidone-K30 (PVP-K30), 0.4% of ethyl cellulose (EC), 7.5% of propylene glycol %, the balance is ethanol.

[0078] Described ethanol is the ethanol that volume concentration is 75%.

[0079] The preparation method of the dragon's blood spray film comprises the following steps:

[0080] (1) Dragon's blood was dissolved in ethanol with a volume concentration of 75%, and made into liquid A for later use;

[0081] (2) Dissolve PVPK30 and EC in ethanol with a volume concentration of 75% to make liquid B for later use;

[0082] (3) Keep liquid A at 60°C for heat preservation, slowly add liquid B and propylene glycol while stirring, continue to stir for 40 minutes, take it out and let it stand for 12 hours, filter, add ethanol with a volume concentration of 75%, and the product is ready.

Abstract

The invention discloses a dragon's blood film spraying agent and a preparation method thereof. The dragon's blood film spraying agent is prepared from the following raw materials in parts by weight: 2to 5% of dragon's blood, 4 to 8% of PVP-K30 (polyvinylpyrrolidone-K30), 0.1 to 0.7% of EC (ethyl cellulose), 7 to 8% of propanediol, and the balance of ethyl alcohol. The dragon's blood film sprayingagent has the advantages that the advantages of plasters, films and air mists are integrated, the preparation method is simple, and the convenience in use is realized; the thickness of the formed film is uniform, the color is uniform, the multiple advantages of large drug loading amount, short filming time, small fluid loss and good filming property are integrated, the macromolecular skeleton material has the air-permeation, water non-permeation and bacteria-inhibiting functions, and the treatment effect is greatly improved; the effects of stopping bleeding, inhibiting bacteria, as well as heeling sore and relieving pain are realized, and the dragon's blood film spraying agent is especially suitable for the symptoms, such as traumatic injury, traumatic bleeding, small-area burn and scald,unheeling of wound and the like.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine preparations, in particular to a dragon's blood spray film preparation and a preparation method thereof. Background technique [0002] Dracaena genus Dracaena genus Liliaceae Dranaena cochinchinensis (Lour.) S. C. Chen's resin extracted from fat-containing wood, mainly produced in Guangxi, Yunnan, etc., in irregular block shape; purple or dark red surface, slight gas, light taste, insoluble in chewing. Dragon's blood has the effects of promoting blood circulation and removing blood stasis, reducing swelling and pain, stopping bleeding and promoting muscle growth, softening hard masses and resolving masses, promoting muscle regeneration and astringent sores, etc. It is mainly used for bruises and traumatic bleeding. Its powder or ethanol solution can be used externally to treat pressure ulcers and Soft tissue injury has a very good therapeutic effect, known as the "Holy Medici...
