Description
Technical field
This utility model belongs to clinical medicine technical field of medical instruments, relates to a kind of catheter of scalable head end perforate size.
Background technology
In recent years, the disease incidences such as prostatic hyperplasia and tumor, tumor of bladder, urinary system calculus remain high, and have and increase trend year by year.These diseases are postoperative all needs conventional indwelling catheter; and be aided with bladder irrigation if desired; but the head end due to traditional catheter only has two little side openings; be difficult to the various situations of satisfied different patient; thus usually having clot or piece of tissue etc. causes catheter to block; severe patient can cause second operation, not only causes considerable distress to patient, also brings numerous trouble to medical personnel.In addition, the folder of traditional indwelling catheter closes Bag for collecting urine place in vitro, easily causes the retrograde urinary by urine.
Summary of the invention
technical problem:the purpose of this utility model solves the problem, and provides a kind of catheter of scalable head end perforate size, meet the demand of the various situation of different patient, have the advantage that structure is simple, easy to operate.
technical scheme:the catheter of scalable head end perforate size of the present utility model, comprise straight catheter, the seal wire that slides, be arranged on the termination of described straight catheter front end, be arranged on the by-pass cock of straight catheter back segment, in the sidewall of described straight catheter, miniature duct is set, described slip seal wire is built in miniature duct, slip seal wire one end connection end, the other end connects by-pass cock.
Further, the miniature duct arranged in described straight catheter sidewall is 3 to 5, and described slip seal wire quantity is identical with miniature duct, the corresponding built-in slip seal wire in each miniature duct.
Further, described straight catheter inwall is provided with the opening being communicated with miniature duct and catheter lumens, slip seal wire enters catheter lumens from opening and is connected with by-pass cock.
Further, described straight catheter tube wall is provided with the chute inside and outside connection, by-pass cock embeds chute and can wherein along straight catheter longitudinal sliding motion, medial wall and the by-pass cock double sided contacts part of described chute are respectively equipped with latch, the two engages each other, and arbitrarily slides and as manual adjustments gear in order to prevent by-pass cock.
Further, described straight catheter is provided with the connecting ring being close to inwall, and described connecting ring is fixedly connected with by-pass cock, and slip seal wire is connected with connecting ring after entering catheter lumens, thus realizes the connection with by-pass cock.
This utility model is provided with the flexible by-pass cock of scalable seal wire at catheter back segment, head end perforate slightly can be turned down when plugging in catheter, can as required perforate be tuned up or close after indwelling, solve catheter to a certain extent and hold susceptible to plugging problem: perforate can be tuned up after indwelling catheter as postoperative, abundant drainage of urine, prevents blocking; Adopt the catheter of scalable head end perforate size, then the perforate of catheter head end can be closed, replace traditional folder and close effect, prevent antidromicity urinary tract infection.
beneficial effect:compared with prior art, this utility model has the following advantages:
(1) on traditional catheter basis, increase the function regulating perforate size, after tuning up perforate, facilitate drain, prevent clot or piece of tissue blocking catheter;
(2) replace traditional external folder to close catheter by closing head end perforate, thus prevent catheter retrograde infection.
Below advantage of the present utility model is made and more specifically describing:
(1) easy to operate.This utility model is provided with by-pass cock at catheter tail end, can manual adjustments end urinary catheter head end perforate size.Plug in catheter step identical with traditional catheter, just need by-pass cock slightly to turn down (not close before plug in catheter, otherwise after inserting, invisible urine flows out), after such insertion by-pass cock is regulated by demand, as by-pass cock then can be adjusted to maximum by postoperative bladder irrigation, so that fully drain, prevents plugging.
(2) structure is simple.This utility model adds slip seal wire and mobilizable head end structure on traditional catheter basis, and manufacturing process is simple, is easy to realize.
(3) applied range.Tradition catheter head end only respectively has a little perforate in both sides, do not consider various special circumstances, and this utility model is by regulating perforate size, numerous purposes can be met, as above-mentioned abundant drain prevents plugging, prevents tradition folder from closing the retrograde infection etc. that catheter causes, also can be applicable to other needs to regulate catheter head end perforate size part.

Have in figure: 1. straight catheter, 2. slip seal wire, 3. termination, 4. by-pass cock, 5. chute, 6. connecting ring, 7. opening.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model, a kind of catheter of scalable head end perforate size, comprise straight catheter 1, the miniature duct that the sidewall intermediate reach of straight catheter 1 arranges hollow, the slip seal wire 2 be built in miniature duct, straight catheter 1 front end is provided with ureter termination 3, and be provided with the flexible by-pass cock 4 of scalable seal wire at back segment, slip seal wire 2 one end connection end 3, the other end is connected with by-pass cock 4.Slip seal wire 2 can be 3 to 5, and every root correspondence is arranged in a miniature duct, only installs a slip seal wire 2, avoid and mutually tangle and disturb in each so miniature duct.Catheter implantation mode and the ordinary urethral catheter of this scalable head end perforate size are similar, only by-pass cock slightly need be turned down (if perforate is too large, then slip seal wire 2 in catheter end is longer, may bend during insertion before insertion catheter; If perforate is closed completely, then catheter is difficult to after inserting see that urine flows out, caused by inconvenient judgment).And after indwelling, then can regulate perforate size according to demand, as bladder irrigation then can be adjusted to maximum, abundant drain, prevents plugging.
Fig. 2 is by-pass cock 4 schematic diagram of catheter tail end of the present utility model.Wherein, 5 for straight catheter 1 sidewall is arranged in order to draw and to install the chute of by-pass cock 4, medial wall and the by-pass cock 4 double sided contacts part of chute 5 are respectively equipped with latch, length is about 1.5cm, the number of teeth about 10, prevent by-pass cock 4 from arbitrarily sliding, and be less than greatly difference " shelves " by manual adjustments perforate.The signable scale in chute 5 side, convenient adjustment catheter head end perforate size directly perceived.6 for converging to connecting ring together by three slip seal wires 2, by-pass cock 4 is coupled through chute 5, is convenient to regulate.Connecting ring 6 is positioned at catheter lumens, is close to catheter medial wall, can not affect urine flowing or clot, piece of tissue discharge.7 for being built in the opening between miniature duct in straight catheter 1 sidewall and catheter lumens, and corresponding place's opening 7 of that root seal wire of each miniature duct and middle setting thereof, length is identical with chute 5, about 1.5cm.Three slip seal wires 2 pass this opening respectively and are connected with connecting ring 6, thus adjustable switch 4 is synchronously transferred.
Above-described embodiment is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from this utility model principle; some improvement and equivalent replacement can also be made; these improve this utility model claim and are equal to the technical scheme after replacing, and all fall into protection domain of the present utility model.
