Problems solved by technology
But it has many defects: (1) There is a gap between the gasket of the Band-Aid and the wound, which is not waterproof, and it is easy to enter dirt and be infected, resulting in prolonged healing time and obvious scars
(2) The adhesive layer of the Band-Aid is airtightly pasted on the skin around the wound. The wounded will feel uncomfortable when using it, and it may cause skin allergies over time.
(3) When the band-aid is removed after use, the spacer may stick to the wound, which not only affects wound healing but also causes pain to the injured
(4) The shape and size of the Band-Aid may not be suitable for the needs of wound treatment, which is inconvenient for wound healing
(5) Band-aids cannot stop bleeding quickly
(6) Band-aids do not have the function of cleaning the wound. If the wound is not properly cleaned during use, it is easy to cause infection
(7) Band-aids are not UV-resistant, and the wounds are prone to skin discoloration when exposed to ultraviolet rays
[0005] These technical solutions can solve existing problems to a certain extent from all aspects, but so far no comprehensive solutions have been proposed.

Abstract
A multifunctional liquid dressing for cleaning wound, fast haemostasis and filing, preventing infection and promoting healing is a liquid sol composed of the superfine inorganic superfine particles (0.01-20%) and the liquid medium (80-99.9%) consisting of water and disinfectant.
Description
technical field [0001] The invention relates to a wound dressing, in particular to a composite functional liquid wound dressing and its application. It belongs to the technical field of medicine for external use. technical background [0002] At present, the band-aid dressing widely used in treating and treating wounds is easy to carry and use, is suitable for treating small wounds, and has been widely accepted and used. But there are many defects in it: (1) gap is arranged between the gasket of band-aid and the wound, can not be waterproof, easily enters dirt and is infected, causes healing time to prolong and cicatrix is obvious. (2) The adhesive layer of the Band-Aid is airtightly pasted on the skin around the wound, and the wounded feel uncomfortable during use, and may cause skin allergies for a long time. (3) When the band-aid is taken off after use, the spacer may stick to the wound, which not only affects wound healing but also causes pain to the wounded. (4) Th...
