Abstract
The utility model discloses a catheter with antimicrobial and hydrophilic coatings, and belongs to the technical field of medical appliances. The catheter has the following structure: the outer surface of the catheter is orderly coated with a layer of antimicrobial coating and a layer of hydrophilic coating, wherein the antimicrobial coating is a coating containing compositions such as chitin or chitosan and derivatives thereof; and the hydrophilic coating is a coating of polyethylene glycol, polyvinyl pyrrolidone or polyvinyl pyrrolidone-vinyl acetate hydrophilic polymer. The structural design that the antimicrobial coating and the hydrophilic coating are orderly coated on the outer surface of the catheter is simple and reasonable, and is favorable for dual effects of antibiosis and lubrication of the catheter; and the catheter is easy to produce on a large scale, has convenient use and operation, can effectively relieve the pain of patients and is convenient to be used by medical workers, is a generation-substituting product of a common catheter, and has good promotion and application values.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of catheter, relates in particular to a kind of antibiotic and catheter hydrophilic coating of having.
Background technology
Medical catheter is one of medical device the most frequently used in the modern medical service practice.Traditional catheter is in its application process, for making conduit insert smooth and easy and avoiding damage to urethra, often need smear lubricant at front end, yet consumption and operation are difficult to hold, lubricant effect is unsatisfactory, and has increased foul link of a step in the feasible operation of the use of this added substance.There is certain sticking absorption on the surface of catheter to microorganisms such as antibacterials simultaneously, antibacterial in the easily subsidiary environment, make and very easily infect in the urethral catheterization process, needs of patients is taken antibiotic prophylaxis and the treatment that human body is had hazardness to a certain degree, and this infection makes therapeutic effect unsatisfactory because of the Drug resistance of antibacterial in the bacterial membrane, and very difficulty becomes.Because the existence of above-mentioned two big defectives needs frequently more to renew catheter, has not only caused sensual misery and financial burden to the patient, has also increased work load to medical personnel.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind of antibiotic hydrophilic coating catheter with surperficial self-lubrication and infection function.
The technical scheme that this utility model adopted is:
This utility model is made up of catheter body, antibiotic layer and hydrophilic layer.Wherein antibiotic layer is coated in the outer surface of catheter body, at the outer surface coating hydrophilic layer of antibiotic layer.Dip-coating mode film forming is adopted in the coating coating.Described antimicrobial coating is the coating that comprises chitin and/or compositions such as chitosan and derivant thereof, and described hydrophilic coating is the coating of hydrophilic polymers such as Polyethylene Glycol, polyvinylpyrrolidone, polyvinylpyrrolidone vinyl acetate.
Effect of the present utility model and benefit are:
1, catheter adopts surperficial self-lubrication technology, hydrophilic polymer is coated in the catheter outer surface, dry back forms clear films, the rapid expansion forms hydrogel after meeting water, lubricant effect reaches highly lubricated effect considerably beyond conventional lubricant, significantly reduces the stimulation to mucous membrane of urethra, and urethral secretions and urine mineralization, reach safety, health, easy to operate.Hydrophilic polymers such as the Polyethylene Glycol that adopts, polyvinylpyrrolidone, polyvinylpyrrolidone vinyl acetate are the macromolecular compounds with good biocompatibility of studying for many years and having facts have proved, itself and all nontoxic at the intravital degradation product of people.
2, the antimicrobial coating of catheter adopts is that chitin or chitosan are as antimicrobial component.Chitin is extensively to be distributed in natural polysaccharide; it is the main component of animal shell; chitosan is the deacetylated product of chitin; chitin verified fully at antibacterial ability, and commute causes that antibacterials such as the escherichia coli, staphylococcus aureus, Candida albicans of urethra inflammation have good fungistatic effect.This anti-biotic material of chitin and chitosan is naturally occurring, and skin is had no stimulation, and is safe and reliable to human body, has no side effect etc.
3, antibiotic hydrophilic coating catheter structural design advantages of simple of the present utility model is convenient to produce and use, and is suitable for promotion and implementation.Earlier at ordinary urethral catheter surface applied ground floor antibiotic layer, then at antibiotic layer surface applied second layer hydrophilic layer, such coating structure design advantage is: when catheter is implanted, hydrophilic coating provides self-lubricating function, make that the catheter surface is super lubricated, catheter is implanted very easily; Catheter exposes antibiotic layer after hydrophilic polymer is water-soluble after implanting, the antibacterial action of performance chitin or chitosan, and have lasting antibacterial action.
Description of drawings
Accompanying drawing is this utility model structural representation.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with technical scheme and accompanying drawing.
This utility model is made up of for three layers catheter body (1), antibiotic layer (2) and hydrophilic layer (3) etc.Wherein antibiotic layer (2) is coated in the outer surface of catheter body (1), at the outer surface coating hydrophilic layer (3) of antibiotic layer (2).Dip-coating mode film forming the most commonly used is adopted in the coating coating.
Antibiotic hydrophilic coating catheter of the present utility model, wherein hydrophilic coating adopts hydrophilic polymer, has self-lubricating function behind the chance water, reduces the frictional resistance when implanting, and is easy to operate, reduces the stimulation to mucous membrane of urethra, can effectively alleviate patient's misery.After catheter implantation back hydrophilic polymer is water-soluble, expose antibiotic layer, the antibacterial action of performance chitin or chitosan, commute cause that antibacterial such as the escherichia coli, staphylococcus aureus, Candida albicans of urethra inflammation has good fungistatic effect, and have lasting antibacterial action.This that antibiotic layer and hydrophilic layer are coated in the structural design of original catheter outer surface successively is simple, easy to use, has antibiotic and lubricated double effects, is patient's Gospel, has also made things convenient for medical personnel.
Claims (3)
1. an antibiotic hydrophilic coating catheter is characterized in that: be made up of catheter body (1), antibiotic layer (2) and hydrophilic layer (3); Wherein antibiotic layer (2) is coated in the outer surface of catheter body (1), at the outer surface coating hydrophilic layer (3) of antibiotic layer (2); Dip-coating mode film forming is adopted in the coating coating.
2. a kind of antibiotic hydrophilic coating catheter according to claim 1, its feature also is: described antibiotic layer (2) is for comprising the coating of chitin and/or chitosan and derivant thereof;
3. a kind of antibiotic hydrophilic coating catheter according to claim 1, its feature also is: described hydrophilic coating is the coating of Polyethylene Glycol, polyvinylpyrrolidone or polyvinylpyrrolidone-vinyl acetate hydrophilic polymer.
