Description
Technical field
The utility model relates to a kind of catheter, especially a kind of expanding catheter.
Background technique
Situations such as catheter is mainly used for urination disorder caused by a variety of causes or needs record unit time urine volume, can be with
It is inserted into bladder per urethram so that drainage of urine comes out, is divided into self retaining catheter and temporary bladder catheter.Temporary bladder catheter is every 4-6
Hour using once, extracts catheter after bladder emptying；Self retaining catheter increases Foley sacculus and check valve, leads
After urinary catheter is inserted into bladder, Foley balloon inflation fixed catheter is stayed in bladder by check valve, and be not easy, in disease
New catheter is just pulled out or regularly replaced to feelings when permitting.
Thickness is different in male urethra stroke, clinical respectively in orificium urethrae internum, film portion and orificium urethrae externum there are three narrow
When to male urethra insertion instrument or catheter, with most difficult by membranous part of urethra stenosis, no matter and men and women, when patient's wing
Guang neck and sphincter urethrae are nervous, or while having pathologic ankylurethria is more difficult to be placed in.At present clinically such as ankylurethria, adopt more
It is inserted by force with adding to apply lubricating oil or use harder catheter instead, not only easily leads to urethral injury, then induce lower urinary tract infection,
But also great pain can be brought to patient.And it is not easy to grasp the insertion depth of catheter during setting pipe, be inserted into
It easily causes catheter in bladder to fold deeply, influences urethral catheterization effect, and increase patient suffering；Being inserted into simple and easy leads to urethral catheterization eyelet not
Into bladder, urethral catheterization failure.
Utility model content
The utility model is to solve existing clinic and set to meet ankylurethria during pipe and set pipe by force to cause asking for urethral injury
Topic, the technical solution adopted is that: a kind of expanding catheter can be used for interim urethral catheterization comprising catheter main body tube, expansion ball
Capsule and power sacculus.There are tip member and urethral catheterization eyelet in main body tube front end, and there is an excretion cone-shaped interface in rear end, has two in tube body
A cavity；Power sacculus has the aperture being in communication with the outside, and can be inflated to dilating sacculus by manual squeezing power sacculus；Expand
It opens sacculus and is located at main body tube tip portion, have the function of dilating urethra after filling up.
Catheter main body tube is a hollow pipeline, and there are tip member and urethral catheterization eyelet in front end, and tip member is setting pipe
It probes at ankylurethria at first in the process, is the entrance of urine in bladder；There is an excretion cone-shaped interface in main body tube rear end, from leading
Urine eyelet enters the urine thus interface discharge of catheter；There are two cavity in main body tube body, the first cavity front end is connected to urethral catheterization
Eyelet, connection excretion cone-shaped interface in rear end is the access that urine flows through, and the second cavity front end is connected to dilating sacculus, rear end connection
Power sacculus is the access for filling up dilating sacculus.Excretion cone-shaped interface is located at main body pipe end, inner cavity from head rearwardly
Direction be gradually increased, and have and be spaced apart, be raised in the band on cavity wall surface on its internal chamber wall, can be connect with urine collection container
Mouth sealing, prevents urine from leaking out and polluting.
Power sacculus is hollow resilient bladder, positioned at the latter half of of main body tube, set be located at after pipe success human urethra with
Outside, power sacculus both ends and the closing of main body tube outer surface connect, and have aperture on the main body tube covered, can connect with the second cavity
Logical, resilient bladder surface has aperture to be in communication with the outside, and aperture can be covered with finger to control gas disengaging by setting pipe in the process.
Dilating sacculus is hollow nipple-like sacculus, is matched with main body tube tip member outer surface, dilating sacculus front end
It is relatively thin, it may expand after inflation, open rearward end is Nian Jie with the sealing of the base portion of tip member, forms a hollow utricule, point
It is through with aperture on part, dilating sacculus can be made to be connected to the second cavity.
Intuitively to grasp catheter insertion depth, in main body wall of the lumen design have one with main body tube pipe shaft it is isometric show
Hachure, which runs through urethral catheterization eyelet, and is separated by urethral catheterization eyelet, and it is tubular that developing line can choose the main body high with transparency
At the color of significant difference, it is easy to observe using X-ray development during setting pipe, and can clearly distinguish the position of urethral catheterization eyelet.
Medical macromolecular materials silica gel, latex, PVC that urethral catheterization tube material can select abiology to endanger etc..
Further, a kind of above-mentioned expanding catheter increases on the basis of main body tube, dilating sacculus and power sacculus
After adding Foley sacculus and check valve, it can be used for indwelling catheter.There are tip member and urethral catheterization eyelet in main body tube front end, and rear end has two
A tail discrimination is excretion cone-shaped interface respectively and fills up cone-shaped interface, and tube body is interior, and there are three cavities, removes the first cavity, the second cavity,
There are also third cavity, third cavity front end is connected to Foley sacculus, and rear end connection fills up cone-shaped interface, and filling up on cone-shaped interface has
Check valve, can be with unidirectionally controlled gas or liquid communication, to play the role of one-way sealing, Foley sacculus position to Foley sacculus
After urethral catheterization eyelet, catheter is stayed in bladder after expansion.
Beneficial achievement of the invention is to increase dilating sacculus on conventional temporary bladder catheter and self retaining catheter and move
Power sacculus.At ankylurethria, the dilating sacculus and tip member of unaerated state probe into first, are made by squeezing power sacculus
Dilating sacculus expansion, the power of generation acts perpendicularly to urethral wall, thus make urethral dilatation but will not damaging mucosal, it is narrow to urethra
After narrow place is opened, and then release action pushes catheter in the power of power sacculus, dilating sacculus deflation, can be smooth
Pipe is set, urethral injury is avoided, thereby reduces the risk of urinary tract infections.Setting pipe can also develop in the process with the use of X-ray,
Convenient for observing catheter insertion depth, pipe success rate is set in increase.
