Abstract
The utility model relates to a medical anti-infectious catheter. The outer surface of the catheter is provided with a silver coating, and the length of the silver coating is larger than the length satisfied with the length contacted with human bodies. The silver coating is formed by adopting the modern vacuum technology to coat silver on the outer surface of the catheter. When the medical catheter is used for the human bodies, the silver and silver ions of the silver coating coated on the outer surface of the catheter can restrain and kill bacteria on the surrounding thereof. Thereby, the infection is prevented, the safety that patients use the catheter is ensured and the therapeutic effect is improved. The medical anti-infectious catheter of the utility model is suitable for the catheter for medical fluid transfusion, urine guide, blood transfusion, etc.
Description
This utility model relates to a kind of medical apparatus and instruments, especially a kind of medical catheter of energy bacterial-infection resisting.
At present, the bacterial-infection resisting problem that is directly used in the medical and hygiene article of human body fails better to solve always.The applicant once did silver plated test on gauze, obtained certain sterilization effect.But up to now, the medical catheter of Shi Yonging remains rubber clinically, and plastics class tubing etc. directly contact with human body, easily cause infection, can increase misery to patient.
The purpose of this utility model is: a kind of medical infection conduit is provided, it is had suppress and kill bacteria, the ability of protecting from infection, and processing technology science, cleaning, pollution-free, raw materials consumption is few.
The purpose of this utility model is achieved in that a kind of medical infection conduit, is coated with silver layer with modern vacuum technology on the outer surface of conduit, and the length of silver coating is greater than satisfying the length that contacts with human body.
Owing to adopt such scheme, when medical catheter was used for human body, the outer surface of conduit contacted with human body, can suppress and kill bacteria around it because this kind silver of catheter outer surface silver coating and silver ion have, the ability of protecting from infection has guaranteed that patient uses the safety of conduit.Thereby reduced misery to the patient, improved therapeutic effect.Because this utility model product only has silver coating in the effective site of the outer surface of medical catheter contact human body, can reduce the consumption of raw material silver, thereby reduce manufacturing cost, alleviates patient's burden.And outer surface is silver-plated, and is also practical on technology.Under vacuum condition, be coated with silver layer, guaranteed processing technology science, cleaning, pollution-free.
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is the structural representation of the medical infection conduit of this utility model
Among the figure, 1. outer surface 3. silver coatings of conduit 2. conduits
Figure 1 shows that an embodiment of the medical infection conduit of this utility model.It is utilize modern vacuum technique on the outer surface 2 of ordinary urethral catheter 1 lining one deck " functional membrane ", should " functional membrane " be silver coating 3.The length of silver coating is slightly larger than the effective length that catheter contacts with human body.For example: for length is 260 millimeters catheter, length is arranged greater than 200 millimeters silver coating 3 on its outer surface 2; Length is 380 millimeters catheter, length is arranged greater than 300 millimeters silver coating 3 on its outer surface 2.Show that through clinical test results medical infection catheter is to escherichia coli, staphylococcus aureus etc. have antibacterial action.
The present embodiment product at first cleans ordinary urethral catheter when producing, and carries out vacuum plating silver then, and forms through encapsulation, sterilization.The vacuum plating silver of this technology has that plated film is even, and corrosion resistance is strong, and is non-stimulated to human body, combines firm characteristics with parent tube, and no residue and cross-contamination produce in technical process, can guarantee the quality of medical catheter.
The medical infection conduit of this utility model also is applicable to various conduits such as medical infusion, blood transfusion except catheter.
Claims (2)
