Embodiment 1

[0014] Example 1 Preparation of purple sweet potato acid-base indicator medical gauze

[0015] Preparation of purple sweet potato pigment: take fresh purple sweet potato root, wash, cut into pieces, dry at 60°C, grind, pass through a 140-mesh sieve to make purple sweet potato powder, use 80% ethanol (hydrochloric acid) with a pH value of 3 Adjustment) extraction, extraction in a constant temperature water bath at 60°C for 1 h, centrifugation at 4000 r / min for 10 min, supernatant was taken, concentrated under reduced pressure, and freeze-dried.

[0016] Preparation of purple sweet potato acid-base indicator medical gauze: add 0.5 g of purple sweet potato pigment to 400 g of distilled water to prepare a dye solution; soak 10 g of gauze in the dye solution at 50°C for 60 minutes; wash with hot distilled water at 40°C for 10 minutes, and dry in the air.

Embodiment 2

[0019] Embodiment 2 prepares Fe 2+ / Al 3+ -Purple sweet potato pH indicator medical gauze:

[0020] The preparation of purple sweet potato pigment is with embodiment 1.

[0021] Preparation of purple sweet potato acid-base indicator medical gauze: add 0.5g purple sweet potato pigment and 0.5g ferrous sulfate to 400g distilled water to prepare a dye solution; soak 10g gauze in the dye solution at 70°C for 60 minutes; wash with hot distilled water at 40°C for 10 minutes , let it dry.

[0022] Put the above acid-base indicating gauze into the pH value adjusted by citric acid, disodium hydrogen phosphate, hydrochloric acid, sodium carbonate, sodium bicarbonate and sodium hydroxide to be 2, 3, 4, 5, 6, 7, 8, 9 respectively , 10, 11 in the solution, after 5 minutes the color develops. The hue value H of medical gauze decreased gradually from 354 to 185 with the increase of pH value. When the pH value is 2, the hue value H of medical gauze reaches 354, the color is bright red, a...

Abstract

The invention provides medical gauze with a pH indicating function. A method for preparing the medical gauze comprises the following steps: adding a purple sweet potato pigment into distilled water to prepare dye liquor; dip-dyeing gauze in the dye liquor at 50-90 DEG C for 60-80 min; and washing with distilled water and air-drying. Acid-base indicating range of the medical gauze is within 3-9 pH. The medical gauze of the invention can protect wounds like common gauze and also can help monitor infection situations of wounds as well as healing conditions of wounds.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a medical gauze with a pH indicating function. Background technique [0002] As we all know, medical degreasing gauze is mainly plain weave cloth woven from pure cotton yarn, which is degreased, bleached and refined. It is mainly used to bandage wounds and prevent wound infection. It is the most commonly used treatment for trauma in surgical operations and outdoor first aid. a dressing material. [0003] Medical gauze with pH indicating function has not been reported yet. Contents of the invention [0004] The purpose of the present invention is to provide a medical gauze with a pH indicating function. The pH value of the wound can be detected by the gauze, which can be used as an auxiliary diagnosis to guide doctors to correctly select anti-infective drugs for treatment, thereby reducing the incidence of infection. [0005] A medical gauze with a pH indicating function provid...
