Abstract
The present invention is a kind of long-acting broad-spectrum antibacterial medical suture.The present invention be with silk (cotton, fiber crops, hair, chemical fibre, blending etc.) line through chemistry and physical treatment, the silver of ultra-fine grain is adhered on the online fiber securely.This kind with the line of ultra-fine grain silver, has significant antibacterial action, and staphylococcus aureus (blue or green quick with drug resistance), bacillus pyocyaneus, colon bacillus, Candida albicans, Staphylococcus albus, gonococcus are had killing action with relevant virus.And have high temperature resistant, wash resistant, and nontoxic, non-stimulated and do not have irritated effect to the people, be fit to operative incision and wound and sew up.
Description
The present invention relates to a kind of long-acting broad-spectrum antibacterial medical suture.
Silver has great sterilization ability, and the present invention is the elemental silver that makes the ultra-fine grain of energy firm attachment on line fiber by the processing of chemistry and physics.The surface area of the ultra-fine grain silver of 1 gram can reach x00-x000m
2Thereby, reached with the silver of minute quantity and can obtain very big silver surface with sterilization ability.Because silver is ultra-fine granular attitude, so also strengthened silver-colored original sterilization ability.The present invention belongs to the antimicrobial treatment of line fiber and application thereof.In operation stitching, might catch multiple morbific pathogen and cause the suture place to infect with virus, influence wound healing, to this, long-acting broad-spectrum antibacterial medical suture has good practical values.
The sterilization ability of silver ancient known it, also the antibacterial tests of multiple pathogen is confirmed in studying for the present invention.Its antibiotic mechanism is as follows:
Ag=Ag
+(when Ag is ultra-fine granular attitude, surface area increases+e, then is beneficial to the dextrad reaction.）
Ag
+Can (SH) combine, make some enzyme loss of activity, and reach sterilization functions with the sulfydryl of pheron in the thalline as necessary base.
Because the antibiotic mechanism of above-mentioned Ag makes the long-acting broad-spectrum antibacterial line with ultra-fine grain elemental silver of the present invention have stronger antibacterial ability.Staphylococcus aureus (blue or green quick with drug resistance), bacillus pyocyaneus, colon bacillus, Candida albicans, Staphylococcus albus, gonococcus there is tangible antibiotic advantage with relevant virus.
The objective of the invention is the firm elemental silver that adheres to ultra-fine on line fiber, make this line have the long-acting broad-spectrum antibacterial ability by chemistry and physical treatment.
Processing technology of the present invention:
A, preparation do not contain any precipitation and muddy silver-containing solution.
Especially on line inevitably with chloride, as NaCl etc., when soaking line, do not produce coarse grained argentiferous granule with silver-containing solution in order to make, therefore Ag-containing solution prescription of the present invention is with crystal AgNO
3Be dissolved in ammoniated aqueous solution and obtain Ag(NH
3)
+ 2True solution, even run into Cl
-The time can not produce coarse grain argentiferous precipitation yet, and reach the purpose that can soak into line equably.
B, add again in the Ag-containing solution after an amount of Reducing agent ascorbic acid stirs evenly above-mentioned making, immediately with line at room temperature, have under the ventilation condition and soak-push-soak-push, make it evenly moistening.
C, with above-mentioned gained line, under ventilation condition, heat-treat, present yellowish-brown to line, on this moment line fiber with ultra-fine grain elemental silver.
D, with the above-mentioned line that makes, put into water through extruding, soak, remove water-soluble substances residual in the line, oven dry more promptly gets the present invention's long-acting broad-spectrum antibacterial medical suture.
Compare prior art, the present invention has following advantage:
1, has broad-spectrum antiseptic ability (seeing attached list 1), existing suture only adopts the sterilization means to make does not have pathogenic bacterium on the line, but do not have an antibacterial ability, and the present invention there is tangible antibacterial action to antibacterials such as staphylococcus aureus (blue or green quick with drug resistance), bacillus pyocyaneus, colon bacillus, Candida albicans, Staphylococcus albus, gonococcuss with relevant virus.As antibacterial medical suture, have the suture that prevents operative incision and wound and infect.
2, has the long acting antibiotic ability, the present invention is through 100 washings, antibacterial ability does not have obviously and weakens, and otch and wound are seamed to take out stitches generally needs 5-10 days, general antibiotic to be difficult to keep long antibacterial effect, and the present invention's antibacterial ability long-time in nothing obviously weaken.
3, the present invention is to human body avirulence, non-stimulated, the irritated effect of nothing.
4, because of the present invention be the elemental silver of ultra-fine grain attached on the line fiber, disinfecting action that therefore can high temperature high voltage resistant is beneficial to the sterilization process of final products.
5, because of the present invention be the elemental silver of ultra-fine grain attached on the line fiber, even long-time storage also undergoes no deterioration, especially can also anti-solar exposure and irradiation under ultraviolet ray, can not produce cracking, qualitative change.
6, technological process is simple, investment is little, cost is low, and it is fast to go into operation.
The invention will be further described by following example:
Take by weighing 5-20 gram AgNO
3(C.P.) be dissolved in 500ml water and the 50-100ml ammonia, be diluted to 1000ml after the dissolving, shake up, the ascorbic acid solution that adds 3-10g again in this solution stirs evenly.With line at room temperature, under ventilation condition, soak-push-soak-push-heat treatment-embathe-dry, promptly get the present invention's long-acting broad-spectrum antibacterial medical suture.The material of line can be silk, cotton, fiber crops, hair, chemical fibre, blending etc.
Subordinate list 1:
The antibiotic strain of long-acting broad-spectrum antibacterial medical suture:
Staphylococcus aureus (blue or green quick) gonococcus
Staphylococcus aureus (drug resistance) bacillus subtilis
The bacillus pyocyaneus dysentery bacterium
The escherichia coli Bacillus typhi
The Staphylococcus albus bacillus enteritidis
The Candida albicans hemophilus influenzae
Streptococcus anaerobius
Claims (2)
1, a kind of long-acting broad-spectrum antibacterial medical suture is characterized in that line (silk, cotton, fiber crops, hair, chemical fibre, blending etc.) fiber surface is attached with ultra-fine grain elemental silver.
2, the manufacture method by claim 1 described long-acting broad-spectrum antibacterial medical suture is characterised in that:
A, preparation do not contain any precipitation or muddy silver-containing solution.The silver solution formula is with crystal AgNO
3Be dissolved in ammoniated aqueous solution, and obtain containing Ag(NH
3)
+ 2True solution,
B, in the above-mentioned Ag-containing solution that makes, add an amount of Reducing agent ascorbic acid again, with line at room temperature, have under the ventilation condition and soak-push-soak-push, make it evenly moistening,
C, with above-mentioned gained line, under ventilation condition heat treatment, the online yellowish-brown that occurs, this moment line firm with ultra-fine grain elemental silver,
D, with the line that makes, put into water through pushing-soak, remove water-soluble substances residual on the line, oven dry promptly gets the present invention's long-acting broad-spectrum antibacterial medical suture.
