Abstract
Ultrasonic coupling agent is used as acoustic conducting medium in ultrasonic diagnosis and inspection. The ultrasonic coupling agent of the present invention has excellent acoustic conductance, high transparency, good stability and no damage to probe, harmful effect to body and pollution to clothing. It consists of sodium polyacrylate,glycol or glycerine, polyvinyl alcohol, light silica, lauryl sidium sulfate, pigment and distilled water.
Description
The present invention relates to a kind of medical apparatus and instruments supersonic diagnostic appts couplant.
As ultrasonic diagnosis and acoustic conductive media---the ultrasonic coupling agent detected, should have the acoustic performance of leading good, do not damage probe, harmless, not pollution clothes, be easy to good characteristics such as cleaning.Present used ultrasonic coupling agent, still have following wherein defective: a kind of is that the higher relatively or used component of cost is many, the 2nd, and appearance transparence is not high, thus acoustic performance is led in influence, the 3rd, chemical stability is relatively poor, can not long preservation, if any prescription in add high nutrients such as agar, sodium alginate, very easily corrosion, though add antiseptic, also should not store for a long time, the 4th, raw material is toxic, and processing safety is poor.
It is lower to the purpose of this invention is to provide a kind of cost, and raw material is easily purchased, transparency height, the ultrasonic coupling agent of good stability.
Of the present invention consisting of, in parts by weight, sodium polyacrylate 2～3, ethylene glycol or glycerol 2～4, polyvinyl alcohol 1.5～3, distilled water 250～300ml.
The sodium polyacrylate of cross-linked network is a primary raw material, promptly is expanded to gel after its suction; And the expansion performance is good, and water absorption rate is 300～700 times; Polyvinyl alcohol (water solublity) makes gel state better, and can delay water evaporates; Ethylene glycol or glycerol have slowed down water evaporates, prolong service time of the present invention, and the ethylene glycol effect is better than glycerol, and distilled water is a solvent.
As adding light silicon dioxide, it is mobile that gel is reduced in the composition, and its addition is 1～1.5 part.
Couplant is coloured as making, and adds toner in the composition and makes toner be dispersed in surfactant in the gel, as sodium lauryl sulphate.
Advantage of the present invention:
(1) constituent is few, and consumption is few, and advantages of nontoxic raw materials is easily purchased, and cost is low.
(2) gelatinous product, the transparency height, it leads acoustic performance extremely near water, after the adding toner, lovely luster, sparkling and crystal-clear bright.
(3) stable performance, the condition that does not have general microorganism to survive can long term store.
(4) pollution clothes does not damage probe, is easy to clean, and is harmless.
(5) technology is simple.
In a word, the present invention promptly reaches low its serviceability, the handling safety of having improved again of cost through repeatedly filling a prescription.
Embodiment one:
Sodium polyacrylate 2.5g, ethylene glycol 2g, polyvinyl alcohol 2.5g, light silicon dioxide 1g, distilled water 250ml.
Method for making: with distilled water and ethylene glycol mix homogeneously, adding the polyvinyl alcohol water-bath again heats about 90 ℃, constantly stir, it is dissolved fully, right turning off stove makes its natural cooling, again sodium polyacrylate and light silicon dioxide is added stirring 30 minutes, make it become gel and get final product, appearance colorless is transparent.
Embodiment two:
Sodium polyacrylate 2.5g, ethylene glycol 2g, polyvinyl alcohol 2.5g, light silicon dioxide 1g, sodium lauryl sulphate 0.5g, serge blue minute quantity, distilled water 250ml.
Method for making: with distilled water and ethylene glycol mix homogeneously, adding the polyvinyl alcohol water-bath again heats about 90 ℃, constantly stir, it is dissolved fully, and right turning off stove makes its natural cooling, add sodium lauryl sulphate again, stir, again sodium polyacrylate and light silicon dioxide are added stirring 30 minutes, make it become gel and get final product.
Embodiment one, two is a most preferred embodiment.
Embodiment three:
Sodium polyacrylate 2g, ethylene glycol 2g, polyvinyl alcohol 1.5g, light silicon dioxide 1.5g, distilled water 280ml.
Embodiment four:
Sodium polyacrylate 3g, glycerol 3g, polyvinyl alcohol 3g, sodium lauryl sulphate 0.5g, serge blue is a small amount of, distilled water 300ml.
Embodiment five:
Sodium polyacrylate 3g, ethylene glycol 4g, polyvinyl alcohol 2g, light silicon dioxide 1.2g, sodium lauryl sulphate 0.5g, serge blue is a small amount of, distilled water 300ml.
What sodium polyacrylate adopted among the embodiment one～five is the super absorbent resin SDL-B type product that Shanghai University Lu Gao chemical plant produces.
