Embodiment 1

[0028] First prepare the spray solution required for spray drying:

[0029] Get the dried white and tubers, and grind them into white and powder particles whose particle size can pass through a 100-mesh sieve for subsequent use;

[0030] Fully mix the obtained Baiji powder with distilled water at 90°C to form a cloudy liquid, so that the Baiji mannan in the Baiji powder can be fully dissolved in the water;

[0031] Centrifuging the obtained turbid liquid and taking its supernatant, adding ethanol with a concentration of more than 90% that is 3 times the volume of the supernatant, so that the white and mannan dissolved in the water form a white flocculent precipitate;

[0032] Filter the resulting white flocculent precipitate, and dry the filter residue to constant weight to obtain purified white and mannan materials;

[0033] The obtained white and mannan material and distilled water are prepared into an aqueous solution, and the concentration of the white and mannan in the a...

Embodiment 2

[0042] First prepare the spray solution required for spray drying:

[0043] Get the dried white and tubers, and grind them into white and powder particles whose particle size can pass through a 100-mesh sieve for subsequent use;

[0044] Fully mix the obtained Baiji powder with distilled water at 60°C to form a turbid liquid, so that the Baiji mannan in the Baiji powder can be fully dissolved in the water;

[0045] Centrifuging the obtained turbid liquid and taking its supernatant, adding ethanol with a concentration of more than 90% that is 3 times the volume of the supernatant, so that the white and mannan dissolved in the water form a white flocculent precipitate;

[0046] Filter the resulting white flocculent precipitate, and dry the filter residue to constant weight to obtain purified white and mannan materials;

[0047] The obtained white and mannan material and distilled water are prepared into an aqueous solution, and the concentration of the white and mannan in the a...

Embodiment 3

[0056] First prepare the spray solution required for spray drying:

[0057] Get the dried white and tubers, and grind them into white and powder particles whose particle size can pass through a 100-mesh sieve for subsequent use;

[0058] Fully mix the obtained Baiji powder with distilled water at 60°C to form a turbid liquid, so that the Baiji mannan in the Baiji powder can be fully dissolved in the water;

[0059]Centrifuging the obtained turbid liquid and taking its supernatant, adding ethanol with a concentration of more than 90% that is 3 times the volume of the supernatant, so that the white and mannan dissolved in the water form a white flocculent precipitate;

[0060] Filter the resulting white flocculent precipitate, and dry the filter residue to constant weight to obtain purified white and mannan materials;

[0061] The obtained white and mannan material and distilled water are prepared into an aqueous solution, and the concentration of the white and mannan in the aq...

Abstract

The invention provides medical hemostatic sponge for the anesthesiology department and a preparation method of the medical hemostatic sponge. The method comprises the following steps: preparing high-expansion sponge; and carrying out spray drying on the surface of the prepared high-expansion sponge, wherein the raw materials used in the spray comprise the extract of common bletilla pseudobulb, namely, bletilla mannan. For the medical hemostatic sponge for the anesthesiology department provided by the invention, the extract of common bletilla pseudobulb, namely, the bletilla mannan layer is sprayed to the surface of the high-expansion sponge, so that the sponge prepared by adopting the preparation method disclosed by the invention has large liquid absorption amount, and causes no allergy phenomenon to a patient.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a medical hemostatic sponge for anesthesiology and a preparation method thereof. Background technique [0002] Hemostasis is the most basic method in the operation of various departments in the hospital. Hemostasis plays a considerable role in the success of the operation and the safety of the patient. For the operation of liver, spleen, brain, kidney and other solid organs, the operation of the diseased tissue with fragile blood vessels, such as tumor, other operations such as tooth extraction, and patients with abnormal blood coagulation function, relying solely on mechanical hemostasis Methods such as ligation, suture, electrocautery, etc. are far from enough, and must rely on the use of auxiliary hemostatic materials. [0003] As an upgraded substitute for traditional medical cotton yarn, high-expansion medical sponges have been widely used in western developed countries. ...
