preparation example Construction

[0027] The present invention also provides a preparation method of a biodegradable medical dressing, which is used to make the above-mentioned biodegradable medical dressing, comprising the following steps:

[0028] S1: cleaning catkins, removing impurities, and then vacuum drying at 40-60°C;

[0029] S2: uniformly mixing catkins and viscose fibers and processing them into catkins / viscose nonwoven fabrics;

[0030] S3: preparation mass fraction is the chitosan finishing liquid of 0.1-0.5g / ml;

[0031] S4: Utilize the chitosan finishing liquid that step S3 configures to catkin / viscose nonwoven fabric to carry out the post-finishing of two dipping two rollings;

[0032] S5: Bake the finished catkin / viscose nonwoven fabric at 80-100° C. for 5-15 minutes.

[0033] In the process of collecting catkins, there will inevitably be dust, leaves and other impurities. When making medical accessories, for hygiene and aesthetics, catkins need to be washed in water to remove impurities, an...

Embodiment 1

[0043] A biodegradable medical dressing, the catkin / viscose mass ratio is 5 / 95. Process catkins and viscose fibers into catkins / viscose nonwovens.

Embodiment 2

[0045] A biodegradable medical dressing, the catkin / viscose mass ratio is 5 / 95. The catkins and viscose fibers are processed into catkins / viscose nonwoven fabrics, and then the catkins / viscose nonwovens are subjected to two-dipping and two-rolling post-finishing through the chitosan finishing solution, and finally the finished viscose nonwovens Bake at 80-100°C for 5-15min.

Abstract

The application discloses a biodegradable medical dressing, which comprises the following raw material components: catkins, viscose fiber and chitosan. The biodegradable medical dressing provided by the present invention uses catkins recycling to produce non-woven medical dressing, turning waste into treasure, and the prepared medical dressing has biodegradability, high water absorption, antibacterial function and hemostasis Function.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a biodegradable medical dressing. Background technique [0002] Spring is the season when catkins are flying all over the sky, and it is also the season of high incidence of various allergic symptoms. The allergies caused mainly occur in the upper respiratory tract. After catkins are inhaled into the nasal cavity, it will cause strong irritation, runny nose, cough and asthma reactions, such as skin itching , redness of the conjunctiva, etc., which can affect sleep in severe cases. Catkins flying all over the sky will also cause a certain degree of damage to the urban ecological environment. Flying catkins will also cause harm to public safety, traffic safety and public facilities. The line of sight of pedestrians and vehicles will affect traffic safety. However, according to medical history records, catkin is a traditional Chinese medicine with cooling and hemostatic ef...
