Abstract
The invention discloses a high-toughness medical cotton swab capable of quickly stopping bleeding. The cotton swab comprises a cotton bar and composite fiber cotton wrapping the end of the cotton bar. The reproducible and degradable composite polylactic acid fiber cotton is used for taking the place of a traditional absorbent cotton ball, production cost is reduced, inherent defects of absorbent cotton are overcome, the prepared composite fiber cotton has good toughness and strength, hydrophilia is effectively improved, and polydopamine-polyethylene glycol is grafted on the surface of the composite fiber cotton so that hydrophilia and biocompatibility of the fiber can be further improved; halloysite doped nanotubes, polydopamine, polyethylene glycol and other raw materials are used together, the cotton swab has the effects of quickly stopping bleeding, sucking liquid, promoting wound healing and the like, and additional application value of the cotton swab is improved.
Description
Technical field
The present invention relates to medical cotton stick technical field, more particularly to it is a kind of can quick-acting haemostatic powder high tenacity medical cotton stick.
Background technology
Medical cotton stick is a kind of very common medical treatment and nursing articles for use, is in materials such as modeling rod, paper rod, wooden sticks by absorbent cotton
Sign pole on roll up cotton molding after obtain, Main Function is to sterilize, sample etc., and use range is quite varied.Due to cotton swab it is direct
With Wound contact, therefore there is to the quality of absorbent cotton higher requirement, the absorbent cotton that traditional medical cotton stick is adopted mostly is cotton
Flower is obtained Jing after alkalilye degreasing, although which has good skin-friendly and water absorption, yet with natural cotton is used, easily
Breed bacteria, and production cost is higher, causes disinfecting cotton swab product made by many absorbent cottons inferior is occurred in that on market, directly
Connect the health for having influence on user.
Polylactic acid is a kind of with carbohydrates such as starch, celluloses as raw material, is made Jing after hydrolysis, fermentation, purification, polymerization
The standby renewable polyester material for obtaining, i.e. the processing characteristics with macromolecule resin, and the compatibility with biomaterial, is one
Preferable Green Polymer Material is planted, and operation suture thread, artificial skin, artificial blood vessel, soft tissue is mainly used as in medical field
Filler, tissue engineering bracket etc., it can be seen that, if replacing traditional absorbent cotton with polylactic acid, by improve cotton swab some lack
Fall into, obtain the higher product of cost performance, lift patient's experience.There is stronger hydrophobicity yet with polylactic acid surface,
Need to be modified which process.《The acid fiber by polylactic of surface grafting polyvinylpyrrolidone is modified》One text is in partial hydrolysiss
Polylactic acid fiber surface graft polymerization polyvinylpyrrolidone, obtains and has certain absorptive modified polylactic acid fiber, but
Be that this method is not easy to large-scale production, and the water absorption of fiber still suffer from larger gap than absorbent cotton, needs do into
The modification of one step.
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided it is a kind of can quick-acting haemostatic powder high tenacity medical cotton
Sign.
The present invention is achieved by the following technical solutions：
It is a kind of can quick-acting haemostatic powder high tenacity medical cotton stick, by swab stick and be rolled in the composite fibre cotton of swab stick end and constitute, it is described
Composite fibre cotton be made up of the raw material of following weight portion：Particles of polylactic acid 12-15, nano-cellulose whisker 1-2, polyoxyethylene
Alkene 3-5, halloysite nanotubes 0.1-0.2, Polyethylene Glycol 4-8, Dopamine Hydrochloride 5-10, Tris-HCl buffer solution are appropriate, go
Ionized water 300-500.
The preparation method of described composite fibre cotton is：
(1) particles of polylactic acid is mixed with nano-cellulose whisker, polyethylene glycol oxide, halloysite nanotubes, high-speed stirred mixing
Melt spinning is carried out after uniform, spinning temperature is 215-225 DEG C, and spinning speed is 2000-3500 m/min, makes average grain
Footpath is standby for 1-15 μm of composite polylactic acid fiber；
（2）First take in the deionized water input reaction vessel of 150-200 weight portions, be subsequently added Dopamine Hydrochloride, stir to which
Tris-HCl buffer solution is added after being completely dissolved, regulation system pH value is 8-8.5, is subsequently dividedly in some parts step（1）Prepare
Composite polylactic acid fiber, immersion treatment 4-5d are standby；
（3）By in the deionized water input reactor of surplus, Polyethylene Glycol is added, is stirred to which and is completely dissolved rear Deca Tris-
HCl buffer solution, regulation system pH value are 8-8.5, are subsequently added into step（2）Composite polylactic acid fiber after middle immersion treatment,
Continue immersion treatment 30-50h, process is taken out after terminating, products therefrom is Jing washing, Jing openers, spice, combing, lapping after being dried,
Obtain final product.
It is an advantage of the invention that：
（1）Replace traditional rayon balls using the composite polylactic acid cellucotton of renewable degradable, reduce production cost, solve
The intrinsic defect of absorbent cotton of having determined, has no adverse effects to skin.
（2）The composite polylactic acid fiber for using is the raw materials such as nano-cellulose whisker, polyethylene glycol oxide, halloysite nanotubes
Obtain with polylactic acid blend spinning, effectively raise the hydrophilic of polylactic acid, while its mechanical property also improved, tool
There are good toughness and intensity, additionally, the composite fiber surface is grafted with poly-dopamine-Polyethylene Glycol, further improve fibre
The hydrophilic and biocompatibility of dimension.
（3）The raw materials such as halloysite nanotubes and poly-dopamine, Polyethylene Glycol that adulterate in the composite fibre cotton are used together, and have
The effects such as quick-acting haemostatic powder, imbibition, promotion wound healing, improve the additional use value of cotton swab.
（4）The cotton swab production process of the invention is simply efficient, the equal reusable edible of links material, to environment without bad
Affect.
