Abstract
The utility model provides an antisepsis super-lubricant duct, which is composed of a duct body and an antisepsis lubricating layer. The utility model is characterized in that the slow-release antisepsis lubricating layer which is composed of water-soluble polymer lubricating material and medical application antimicrobial material is coated on the external surface of the duct body as one-time usage. Compared with the prior art, the antisepsis super-lubricant duct has the advantages of convenient use, high technical content, high added value, and easy scale production, and reduces the pain of patients and the infect of the genitourinary system. The utility model can replace an ordinary urethral catheter.
Description
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of antibiotic super lubrication conduit.
Indispensable medical apparatus when catheter is clinical catheterization.In recent years, the kind of catheter constantly increases, the main purposes form that is it that changes, and as single chamber, multi-cavity and with washing function, kind is overstepping the bounds of propriety thin more.But the in use existing deficiency of the ordinary urethral catheter of prior art is that the frictional resistance between urethral catheterization tube wall and the urothelial tissue is big, patient has intensive calcination and pain during intubate, easy damaged urothelial tissue and cause accompanying infection very in the therapeutic process in addition, and troublesome poeration, need be coated on the tube wall lubricated to increase with lubricating oil, thereby all bring a lot of inconvenience for patient and doctor.The superslide catheter can solve the lubrication problem when using well, has alleviated patient's misery greatly.But for the retained type catheter, because of foreign body stimulates the infection symptoms that causes still inevitable.Common catheter was placed after 5 days, and infection symptoms can appear in 70% patient, surpassed 7 days, and infection rate reaches 100%, became the subject matter that exists when catheter uses now.Domestic hospital all uses ordinary urethral catheter at present, gives clinical many troubles of bringing because of difficult problems such as friction and indwelling easy infections, is badly in need of improving.Therefore, developing the superslide catheter with antibacterial action has very important significance clinically.Antibiotic superslide catheter will become the renewal product of ordinary urethral catheter.
At present, antibiotic catheters and superslide catheter all respectively have product to sell abroad, but not only antibiotic but also product superslide also comes out.At home, the catheter with anti-microbial property yet there are no report.Along with improving constantly of people's lives and medical level, development with medical apparatus of combination property more and more comes into one's own, and antibiotic superslide urethral catheterization integrates multiple function, both brings comfortable, safety to patient, bringing convenience to the doctor again, is the inexorable trend of catheter future development.
The purpose of this utility model provides a kind of and has the antibiotic super lubrication conduit that lubrication has antibacterial action again.
The purpose of this utility model realizes in the following manner, what employing had been generally acknowledged clinically has the high-efficiency broad spectrum antibiotics of good curative effect as effective active components to urogenital infections, as release vehicle, both mix to be coated on the outer wall of catheter as the antibacterial lubricant layer and make antibiotic superslide catheter with the water-soluble high-molecular material in the superslide liquid.
This antibiotic superslide catheter has following innovation part:
1, because catheter surface contains the urinary tract infection that high-efficiency broad spectrum antibiotics can prevent effectively that the indwelling owing to catheter from causing.
2,, the time can reduce calcination and the pain that patient causes the friction of conduit in operation because conduit has super lubrication property.
3, the water solublity host molecule material of leading the official surface has slow releasing function, the concentration of antibacterials can remained on the effect level during the urinary catheter in, guarantees that antibacterial efficacy is no less than 7 days, has so just reduced the incidence rate that infects widely.
Accompanying drawing is the structural representation of antibiotic super lubrication conduit;
Explain below with reference to Figure of description antibacterial super-lubricant duct of the present utility model being done.
Antibacterial super-lubricant duct of the present utility model, its structure are to be made of body 1, antibacterial lubricant layer, Mixing the slowly-releasing antibacterial lubricant layer that forms by water soluble polymer lubriation material 2 and antibiotic material in medical use 3 does Be coated in for disposable use on the outer surface of body 1.
Embodiment:
Antibiotic its processing and fabricating of super lubrication conduit of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Use same as the prior art.
Antibiotic super lubrication conduit of the present utility model, antibacterials adopt externally used antimicrobial medicine povidone iodine commonly used clinically as effective antibiotic composition, make slow release antibacterial lubricant layer with medical water-soluble high-molecular material, the active gene of povidone iodine energy oxidation pathogen plasmosin, and energy and protein bound, make its degeneration precipitation, antibacterial, spore, virus etc. are all had powerful killing action, and can be used on the mucosa.Medical water-soluble high-molecular material be made as current techique.
China has more than 1.4 ten thousand families of all kinds of hospital above county level now according to statistics, and annual about 1,000 ten thousand more than of the catheter that consumes is a very large market.And antibiotic superslide catheter possesses skills content height, added value height, be easy to the characteristics of large-scale production.If whole or most of ordinary urethral catheters that replace will be obtained considerable economic, therefore, have good value for applications.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
