Description
Technical field
This utility model relates to field of medical technology, is specifically related to a kind of Novel urethral catheter.
Background technology
Catheter is the pipeline made with natural rubber, silicone rubber or polrvinyl chloride (PVC), through per urethram inserting bladder, an air bag can be had to fix catheter and staying intravesical, and not easily deviate from, so that drainage of urine out near catheter head end.Usually adopt clinically and encourage patient to drink more water or increase the mode of amount of infusion or adopt bladder irrigation to increase Urinary liquid measure, the effect preventing urinary calculi from being formed is played by irrigating catheter, but the time of rinsing cannot ensure, need to observe conduit etc., often just there is a lot of urinary calculi when finding, periodic flushing then brings temporal waste and unnecessary money, improves the medical expense of patient.
In practical operation, the problem of difficult intubation is there is in many patients because of soft catheter, assist so need again to wear a wire guide in catheter, wearing in process like this, catheter tube wall contacts with urethra direct friction type and advances, cause urethra to have damage, and catheter easily damage by wire guide, is unfavorable for the treatment of patient when exerting a force.And the degree that stretches into of catheter to be all generally the data that provide with B ultrasonic etc. and the experience of self plug, so have certain drawback, intubate fault rate improves.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of Novel urethral catheter, and this utility model structure is simple, and intubate is convenient, and has good bacteriological protection infection, improves the result of use of patient.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is achieved through the following technical solutions:
Novel urethral catheter, comprise catheter body and air bag, described catheter body surface is provided with scale strip and is arranged with fairlead, described fairlead surface-coated has tranilast coating, and described catheter body one end is set to oval implantation and holds, and the other end is connected with urinal, described ellipse is implanted on end and is provided with urethral catheterization hole, described ellipse is implanted on end inwall and is provided with dirty proof layer, and described dirty proof layer side abuts with Medical check valve, and described Medical check valve is fixed on catheter body interior.
Further, the material of described dirty proof layer is polypropylene random copolymer.
Further, described catheter body is positioned at oval implantation on end and is provided with medicine mouth spray, and described medicine mouth spray is connected with injection canal one end, and the described injection canal other end is connected with drug injection mouth.
Further, described fairlead is positioned at oval surface of implanting end side and is provided with silicon rubber film, is provided with and dodges hole in the middle part of described silicon rubber film.
Further, the thickness of described silicon rubber film is 0.25-0.5mm.
The beneficial effects of the utility model are:
This device, by being coated with the fairlead of tranilast coating as support, catheter body can easily be inserted, and tranilast coating effectively can prevent injury of urethra or Post operation urethral stricture, is conducive to wound healing.Dirty proof layer adopts polypropylene random copolymer, has corrosion-resistant, non-scaling, health, the effect such as nontoxic, improves safety, and become urinary calculi blocking catheter after preventing urine fouling.Medical check valve stops that antibacterial enters bladder from catheter body interior, stops the bad phenomenon such as urine or urinary calculi backflow, improves result of use.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment technology, be briefly described to the accompanying drawing used required in the description of embodiment technology below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is implantation end portion structural representation of the present utility model;
Fig. 3 is fairlead part-structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Embodiment one
Shown in Fig. 3, Novel urethral catheter, comprise catheter body 1 and air bag 2, catheter body one end is set to oval implantation end 5, the other end is connected with urinal (depending on not going out in figure), catheter body surface is provided with scale strip 14 and is arranged with fairlead 3, fairlead surface-coated has tranilast coating 4, first insert in urethra with fairlead, enough insertions can be provided for catheter body, can not be difficult to insert because of material problem, and fairlead is positioned at oval surface of implanting end side is provided with silicon rubber film 12, be provided with in the middle part of silicon rubber film and dodge hole 13, for dodging catheter body.The thickness of silicon rubber film is 0.25mm, and material is thin, and resistance is little, catheter body inserts easily and fast, and owing to being silicon rubber film, its material itself has superior elasticity, can not break, so it is little to dodge hole opening, be generally 5-8 millimeter, can prevent antibacterial from entering, but not hinder the insertion of catheter body, can closely abut with catheter body, cleanliness factor is ensured in operation, operation terminates rear fairlead and does not take out and also can use, and takes out and only needs to pull, easy to operate.
