Problems solved by technology

When the skin is damaged due to trauma, gunshot wounds, burns, and ulcers, it is easy to cause bacterial contamination, water loss, inflammation, pain and other complications. During treatment, medical dressings are needed to protect the wound and promote wound healing. Traditional Medical dressings commonly used in absorbent cotton or cotton gauze, viscose fiber, etc. are processed into medical dressings. When in use, they are directly applied to the wound, and they can stop bleeding and cover the wound by pressing. However, when the wound is healing, dressings often appear. Adhesion to the wound is not suitable for wound healing. When changing the dressing, it will cause secondary damage to the wound and bring pain to the patient. Trauma wounds are characterized by exposed intradermal tissue, which is easy to be infected, and there will be a large amount of blood or effluent in the wound

Embodiment 1

[0018] Step 1: compound vaseline preparation, under the condition of 38°C and 3000r / min high-speed stirring of vaseline, add tea polyphenols and superfine powder of Cordyceps militaris above 400 mesh. The mass ratio is: petrolatum: tea polyphenols: Cordyceps militaris = 1000: 8: 6.5.

[0019] Step 2: Heat the compound vaseline to 50°C, let the bamboo fiber gauze be soaked quickly, and the amount of compound vaseline contained in the soaked bamboo fiber gauze by controlling the speed is 210g / m 2 .

[0020] Step 3: Rapidly cool the bamboo fiber gauze impregnated with compound vaseline, use the inner and outer layer double-tube mesh to blow air from top to bottom, the inner tube is sprayed with powder, and the ultra-fine powder sprayed is chitin, so that the chitin is in the bamboo The side of the fiber gauze in contact with the wound is evenly distributed, and the amount of powder sprayed is 0.21g / m 2 ; The outer tube is blown, and the blowing temperature is -28°C to ensure th...

Embodiment 2

[0025] Step 1: Composite vaseline blending, under the condition of 40°C and 3500r / min high-speed stirring of vaseline, add chitosan above 400 mesh and superfine powder of Cordyceps militaris. The mass ratio of feed is: petrolatum: chitosan: Cordyceps militaris = 1000: 2: 6.5.

[0026] Step 2: When the compound vaseline is heated to 45°C, soak the chitosan gauze quickly, and the amount of compound vaseline contained in the soaked chitosan gauze by speed control is 220g / m 2 .

[0027] Step 3: Rapidly cool the chitosan gauze impregnated with compound vaseline, use the inner and outer double-tube mesh to blow air from top to bottom, the inner tube is powder sprayed, and the sprayed ultrafine powder chitosan is coated and compounded Vaseline gauze and wound contact surface distribution, powder spraying amount is 0. 10 g / m 2 ; The outer tube is blown, and the blowing temperature is -25°C to ensure that the compound vaseline is condensed on the medical gauze.

Abstract

The invention provides a production method of a surgical dressing by irradiation sterilization, and relates to the technical field of production of surgical dressings. The production method is characterized in that natural-occurring substance powder with the functions of fighting bacteria, diminishing inflammation, reducing scars, promoting wound healing and relieving pain is mixed with vaseline to obtain composite vaseline, the vaseline is combined with a medical gauze, and then the processed medical gauze is sterilized in an irradiation manner, thus the surgical dressing by irradiation sterilization has outstanding coverage, and can prevent a wound from mechanical injury, polluting and chemical stimulation, resist dry, moisture and secondary infection, reduce the loss of electrolyte and energy, actively promote the wound healing, and change the micro-environmental impact; in addition, the surgical dressing cannot be adhered with the wound, so that the wound healing is promoted, and no second damage is brought to the wound during dressing change.

Description

technical field [0001] The invention relates to the technical field of production of medical dressings. Background technique [0002] Human skin is composed of epidermis, dermis and subcutaneous tissue. It has important functions such as resisting the invasion of pathogenic bacteria outside the body, excreting human waste, preventing the evaporation of water in the human body, regulating the temperature of the human body, and feeling the stimulation of pressure, temperature and chemicals. When the skin is damaged due to trauma, gunshot wounds, burns, and ulcers, it is easy to cause bacterial contamination, water loss, inflammation, pain and other complications. During treatment, medical dressings are needed to protect the wound and promote wound healing. Traditional Medical dressings commonly used in absorbent cotton or cotton gauze, viscose fiber, etc. are processed into medical dressings. When in use, they are directly applied to the wound, and they can stop bleeding an...
