Abstract
Provided is a urethra expansion conduit. The main body of the urethra expansion conduit comprises a urethra expansion conduit body, a mounting fixture, and a metal bend bougie. The urethra expansion conduit body is formed by the successive connection of a front soft end, a front side hole, a front air bag, a rear air bag, a conduit cavity, and an end joint, the rear air bag is provided with length scales of the urethra expansion conduit body, and the mounting fixture is composed of a fixing block and a fixing clamp. The urethra expansion conduit can be used as a common catheter, and also can be used as a urethra probe to smoothly pass through a narrow urethra and continuously expands the urethra by discontinuous pressurization, and the urethra expansion conduit can be kept during the urethral catheterization, and the outside of the urethra expansion conduit is provided with a fixing device for displacement prevention. The urethra expansion conduit is super smooth and antibacterial. In addition, the urethra expansion conduit is simple in structure, reasonable in design, safe and reliable to use, and convenient to popularize and use.
Description
Technical field
The present invention relates to a kind of urethral dilatation conduit.
Background technology
For condition subject such as urethral stricture patient or senile prostatic hypertrophy, prostatitis and injury of urethra, because the internal diameter of urethra, traveling and flexibility change, often there is difficult intubation in common urethral catheterization mode.With the expansion of metal divulsor, then need from trumpet to large size polytypic repeatedly dilating urethra, the operating time is longer, increases patient suffering again, and during the urethral catheterization of metal divulsor, inconvenience retains, and thick catheter is still difficult to insert.
Existing Foley catheter outer end does not have good fixing, causes catheter inwardly to slide, air bag can not with good the coincideing of internal urethral orifice, cause the outside seepage of urine.
Summary of the invention
For above-mentioned deficiency of the prior art, a kind of urethral dilatation conduit is provided, can either uses as ordinary urethral catheter; As urethral probe, smoothly by narrow urethra, and can be interrupted pressurization continuous expansion urethra again; Also can indwelling catheter, there is the fixture of anti-displacement its outside.Its structure is simple, reasonable in design, safe and reliable, is convenient to promote the use of.
The concrete technical scheme of the present invention is: per urethram dilating catheter, holder and metal bends bougie are formed the main body of urethral dilatation conduit.Wherein: urethral dilatation conduit is connected and composed in turn by the soft head in front end, front side opening, frontal air bag, rear end air bag, catheter lumen and end fitting head, rear end air bag has the scale of urethral dilatation catheter length; Holder is made up of fixed stop and fixation clamp.The soft head in front end of urethral dilatation conduit has certain toughness, and its inside is fluted.Front side opening at the rear portion of the soft head in dilating catheter front end, road, Hua Buchu front, metal bends bougie front end side opening.Frontal air bag is attached to outside catheter lumen, and its gas injecting pipe front opening is in air bag, and the unidirectional gas injection valve of frontal air bag of gas injecting pipe end is positioned at air bag rear, rear end.Front end gas injecting pipe can walk in the air bag of rear end, in catheter lumen, on catheter lumen wall, in catheter lumen internal layer.Rear end air bag is attached to outside catheter lumen, is positioned at frontal air bag rear portion, and its gas injecting pipe front opening is in air bag, and the rear end air bag unidirectional gas injection valve of gas injecting pipe end is positioned at frontal air bag unidirectional gas injection valve rear.Rear end air bag is overall column, also can be segmentation column.As being segmentation column, then each column air bag can have the unidirectional gas injection valve of respective rear end air bag.Rear end air bag there is the scale of display urethral dilatation catheter length.After fixation clamp is opened, holder can move on rear end air bag and catheter lumen, after fixation clamp is fixing, the holder rear portion of rear end air bag can be stoped inflate, the glans penis side (human body contact portion) of fixed gear can have for the groove of breathing freely or (and) aperture.Metal bends bougie head-bent, afterbody is flat, hollow form, circle, ellipse, and metal bends bougie also can be plastics etc., and other have the elbowed bougie of certain degree of hardness and elastomeric material.
Urethral dilatation conduit can be superslide antimicrobial form.The antibiotic layer that its surface can have antibacterial agent, nano metal etc. to make or have one deck water-soluble chitosan layer at the outer surface of povidone iodine layer.

Detailed description of the invention
Purposes 1, applies as common compact Foley catheter.After extracting the metal bends bougie in catheter lumen, conventional urethral catheterization, fill frontal air bag with normal saline.After opening fixation clamp, mobile holder is at the correct position of rear end air bag, and fixation clamp is fixed, i.e. complete operation.
Purposes 2, dilating urethra is used.Metal bends bougie is inserted in catheter lumen, urethral dilatation conduit is inserted to intravesical by urethral probe application operating routine, extract the metal bends bougie in catheter lumen, after having urine to flow out, fill normal saline to frontal air bag, outside tractive urethral dilatation conduit to there being resistance, after opening fixation clamp, mobile holder is at the correct position of rear end air bag, and fixation clamp is fixed.Fill normal saline slowly to rear end air bag or air only can not tolerate to patient, after the patient that waits for a period of time adapts to, then fill a small amount of normal saline or air slowly to rear end air bag.The safe patient of the expansion slowly urethra continued can be reached like this.
For the patient after urethral dilatation once, later can Self-operating, oneself expansion, removes from and waits in line the inconveniences such as treatment to hospital, also can remain next record expense.
This urethral dilatation catheter proximal end is silica gel or the plastic cement of flexible, and protection metal bends bougie, prevents it from wearing out catheter and cause injury of urethra to patient.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solution of the present invention.
