Abstract
A medical ultrasonic wave conducting gel is proportionally prepared from cross-linked polyacrylic resin, sodium alginate, chlorhexidine acetate, deionized water and polyethanediol through mixing, immersing for 24 hr, slow stirring while adding solution of sodium hydroxide to regulate pH=7, and adding deionized water. Its advantages are high affinity to skin, and high power to kill gram-positive and gram-negative bacteria.
Description
(1) technical field
What the present invention relates to is a kind of medical material, the auxiliary material that specifically a kind of ultrasonic diagnosis is used.
(2) background technology
At present, the ultrasonic coupling agent of selling on the market normally adopts carbomer behind the water logging swelling, is neutralized to pH value with sodium hydroxide and equals 7, adds antiseptic again and makes.The ultrasonic coupling agent that also has adds glycerol on this basis, as wetting agent.The common defects of these products is: leading acoustic performance has certain limitation; Affine adhesion property to skin is relatively poor; Do not have antibacterial action etc.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly lead sound effective value and affine performance is better, and have the medical supersonic conductive gel of good antibacterial performance.
The object of the present invention is achieved like this: it is with crosslinked polypropylene diluted acid resin 2-3 gram, sodium alginate 0.04-0.06 gram, chlorhexidine acetate 1-3 gram, add in 600 ml deionized water, add 30 milliliters of Polyethylene Glycol again, soaked 24 hours, it is 20% sodium hydroxide solution that limit adding weight ratio concentration is slowly stirred on the limit, adjust pH equals 7, adds deionized water to 1000 milliliter resulting product again.
Major advantage of the present invention is embodied in:
1, product of the present invention has added Polyethylene Glycol (PEG400), has increased the relative density of product, has improved the main acoustics index of product, has especially increased substantially the velocity of sound of product.And Polyethylene Glycol (PEG400) also has the bacterial growth of inhibition, the lubrication of preserving moisture.The acoustical behavior of product of the present invention is through Acoustical Inst., Chinese Academy of Sciences's check checking.
2, product of the present invention has added ocean macromolecular material-sodium alginate, having strengthened product is adhesion property to the affine of skin, and product can mildly be soaked at skin surface, has reduced the isolation between couplant and skin, the experimenter is felt comfortably cool, also strengthened the acoustic performance of leading of product simultaneously.
3, product of the present invention has added the antimicrobial component chlorhexidine acetate, makes product have the disinfective action that has equal effect with high effect disinfectants.According to investigations, at present the B ultrasonic that uses in the hospital, the probe of color ultrasound are not all accomplished a person-time sterilization basically, are easy to cause the cross infection of skin bacterium, especially after dermatosis patient uses more very.The antimicrobial component chlorhexidine acetate that this product includes is 2000 editions Pharmacopoeia of the People's Republic of China product, gram positive bacteria, negative bacterium there is very strong killing action, can in 10 minutes, kill the pathogenic bacterium of skin surface, can prevent effectively that ultrasonic diagnostic probe from using the cross infection that causes at different patients.Simultaneously chlorhexidine acetate also plays anticorrosion, anti-going mouldy effect as antiseptic in product, and this composition is nontoxic, tasteless, nonirritant, ametaboly are reacted.
Product of the present invention does not damage instrument probe, pollution clothes not, and manufacturing process is simple, and is with low cost, clinical easy to use, is a kind of medical supersonic conductive gel with wide application prospect.
(4) specific embodiments
For a more detailed description to the present invention for example below:
With crosslinked polypropylene diluted acid resin 2-3 gram, sodium alginate 0.04-0.06 gram, chlorhexidine acetate 1-3 gram, add in 600 ml deionized water, add 30 milliliters of Polyethylene Glycol again, soaked 24 hours, it is 20% sodium hydroxide solution that limit adding weight ratio concentration is slowly stirred on the limit, adjust pH equals 7, adds deionized water to 1000 again and milliliter obtains product.
With crosslinked polypropylene diluted acid resin 2.5 grams, sodium alginate 0.05 gram, chlorhexidine acetate 2 grams, add in 600 ml deionized water, add 30 milliliters of Polyethylene Glycol again, soaked 24 hours, it is 20% sodium hydroxide solution that limit adding weight ratio concentration is slowly stirred on the limit, adjust pH equals 7, adds deionized water to 1000 again and milliliter obtains product.
Claims (2)
1, a kind of medical supersonic conductive gel, it is characterized in that: it is with crosslinked polypropylene diluted acid resin 2-3 gram, sodium alginate 0.04-0.06 gram, chlorhexidine acetate 1-3 gram, add in 600 ml deionized water, add 30 milliliters of Polyethylene Glycol again, soaked 24 hours, it is 20% sodium hydroxide solution that limit adding weight ratio concentration is slowly stirred on the limit, and adjust pH equals 7, adds deionized water to 1000 milliliter resulting product again.
