To realize the object of the invention, the technical scheme for adopting for：A kind of catheter with sterilizing function, including body, Characterized in that, the rear portion of the urine filling mouth of the body has inflating balloon；Penis guarantor is arranged with the outer tube wall of the body Sheath, penis protective case is in top seal, the tubular of bottom opening, and the penis protective case is coaxial with body, penis protective case Top be tightly connected with tube wall, the inwall bottom of penis protective case is provided with Medical adhesive tape, on the outer wall of protective case wind There is elastic cord；The body is provided with body fixing device above penis protective case, and body fixing device includes being set in pipe Housing on body, the inner headed face of housing is coned face, and between the periphery of body and the inner headed face of housing annular sleeve is provided with；Institute The periphery for stating annular sleeve is taper surface, and is engaged with the coned face of housing；The inner headed face of the annular sleeve and body Periphery is engaged；Spring is provided between the large end face of the annular sleeve and corresponding inner walls；Body is arranged on spring It is interior, and spring one end is connected with inner walls, the spring other end is connected with the large end face of annular sleeve；The both sides difference of the housing The first fixing band and the second fixing band are provided with, the back side of the second fixing band is coordinated by adhered layer with the front of the first fixing band and connected Connect；The outer surface of the body is coated with a nanometer silver coating.
Further, the annular sleeve is elastomeric material.
Further, the adhered layer includes the lower adhered layer that the back side of the second fixing band is arranged, and the first fixing band Front arrange upper adhered layer.
The invention has the beneficial effects as follows,
During the first, one end of body to be inserted the bladder of patient, it is clamped in bladder by inflating balloon, now urine passes through urethral catheterization Pipe draws external, can prevent catheter from coming off.
2nd, by spring promote annular sleeve move down, due to annular sleeve periphery be taper surface, and with the circle of housing Taper surface is engaged, and makes annular be locked body, so that body fixing device is fixed on body, then by the second fixing band The back side is coordinated with the front of the first fixing band by adhered layer, is tied up on the thigh of patient, prevents catheter from coming off.
3rd, after body insertion urethra, penis protective case is enclosed within the penis of male patient, and with Medical adhesive tape and elastic Band is fixed on penis, and now, male urethral orifice is isolated from the outside, so as to ensure that infection will not be caused.
4th, the outer surface of body is coated with a nanometer silver coating, preferably improves the antibiotic property of catheter so that catheter is not Only have in disinfective action, and the urethra to patient, bladder and contact antibacterial, the funguses at place etc. with bactericidal action, use Effect is more preferable.
Description of the drawings
Fig. 1 is a kind of dimensional structure diagram of catheter with sterilizing function that the present invention is provided；
Fig. 2 is the structural representation of body；
Fig. 3 is the structural representation of penis protective case.
Specific embodiment
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Fig. 1-3 shows the catheter with sterilizing function of present invention offer, including body 1, inflating balloon 2, penis Protective case 6, penis 7, the first fixing band 3, the second fixing band 4, housing 8, spring 9, annular sleeve 10, upper adhered layer 11 and lower stickup Layer 12, nanometer silver coating 20, urine filling mouth 22, elastic cord 13 and Medical adhesive tape 14.The rear portion of the urine filling mouth of the body 1 has to be filled Balloon capsule 2；Penis protective case 6 is arranged with the outer tube wall of the body 1, penis protective case 6 is in top seal, bottom opening Tubular, the penis protective case 6 is coaxial with body 1, and top and the outer wall of body 1 of penis protective case 6 are tightly connected, penis protection The inwall bottom of set 6 is provided with Medical adhesive tape 14, and elastic cord 13 is wound with the outer wall of protective case 6；The body 1 is protected in penis Body fixing device is provided with above set, body fixing device includes the housing being set on body, and the inner headed face of housing is circle Taper surface, between the periphery of body 1 and the inner headed face of housing 8 annular sleeve 10 is provided with；The periphery of the annular sleeve 10 is cone Shape face, and be engaged with the coned face of housing 8；The inner headed face of the annular sleeve 10 is engaged with the periphery of body 1；Institute State and be provided with spring 9 between the large end face of annular sleeve 10 and the inwall of corresponding housing 8；Body 1 is arranged in spring 9, and spring 9 one End is connected with the inwall of housing 8, and the other end of spring 9 is connected with the large end face of annular sleeve 10；The housing 8 is respectively provided on two sides with One fixing band 3 and the second fixing band 4, the back side of the second fixing band 4 is coordinated by adhered layer with the front of the first fixing band 3 and is connected Connect；The outer surface of the body 1 is coated with nanometer silver coating 20；The annular sleeve 10 is elastomeric material；The adhered layer includes The lower adhered layer 12 that the back side of the second fixing band 4 is arranged, and the upper adhered layer 11 that the front of the first fixing band 3 is arranged.
