Description

A kind of medical ultrasonic coupling agent and preparation method thereof

Technical field

The invention belongs to medical inspection reagent technique field, specifically a kind of medical ultrasonic coupling agent and preparation method thereof.

Background technology

Medical ultrasonic coupling agent is that a kind of filling of needing to use in ultrasonic diagnosis and therapeutic process or be coated on is popped one's head between radiating surface and human epidermal, mucosa, in order to the ultrasonic neutral medium of transmitted acoustic pulse.Ultrasonic coupling agent plays a part to determine good and bad and even success or failure in ultrasonic diagnosis and treatment operation, in clinical practice, not only play a part entrant sound medium, also play a part lubricant, be concerned about also is not only its acoustic characteristic clinically, also has safety and effectiveness target, wherein, effectiveness is mainly conceived to entrant sound effect, and safety is mainly conceived to the impact on tissue and the defence to cross infection.

Existing medical ultrasonic coupling agent is mainly with hydroxyethyl-cellulose, hydroxypropyl cellulose, one among carbomer is as viscosity modifier, be equipped with propylene glycol solvent again and deionized water is formed by combining, or be equipped with disinfection sanitizer composition again, its effect is when clinical ultrasonic diagnosis or ultrasonic therapeutic, coupling is set up between sound head and human body, enable sound head the ultrasound wave sent out enter human body smoothly, to obtain reliable checkout and diagnosis image, or reach effective therapeutic purposes, but due to the intermiscibility problem of antibacterial and aqueous high molecular gel preparation cannot be solved, antibacterial type product is caused to lump and muddiness, and antibacterial effect is also not ideal enough, also may can produce certain corrosion and stimulation to the patient skin of being checked in clinical practice.

Along with the modernization development of China's herbal industry, there is the medical ultrasonic coupling agent that medicinal herb components is made, as patent of invention CN104127892A, CN103961327A, CN103751812B, CN103341184B etc., having much room for improvement in gelation and compatibility aspect of this type of medical ultrasonic coupling agent, though it is not there is effect that is antibacterial and treatment, remarkable.

Povidone iodine be a kind of novel efficient, wide spectrum, zest are little, have no side effect, noresidue, without Drug resistance antibacterial.It has stronger killing action to staphylococcus aureus, bacillus pyocyaneus, hepatitis B virus, HIV (human immunodeficiency virus), trichomonas vaginitis, spore etc., almost can kill antibacterial common clinically.The product or the technology that use povidone iodine to make gel is had in prior art, as patent of invention CN102657600A discloses a kind of povidone iodine gel for veterinary use and preparation technology, but this gellike is applied few in ultrasound medicine, entrant sound effect and ultra sonic imaging effect relatively poor.

Summary of the invention

The present invention is directed to the above-mentioned defect that prior art exists, provide that a kind of safety is high, antibiotic property good, the medical ultrasonic coupling agent of entrant sound Be very effective, imaging clearly, additionally provide the preparation method of this medical ultrasonic coupling agent.

To achieve these goals, the present invention is achieved by the following technical solutions:
