Description
Technical field
The invention belongs to technical field of medical instruments, more particularly to a kind of catheter.
Background technology
Catheter is a kind of with pipeline made by natural rubber, silicone rubber or polrvinyl chloride, for urine is led from bladder
To external.Catheter belongs to clinical conventional medical intrusive mood material, inserts patient's urethra via urethra, and catheter extends wing
Catheter is fixed on the urethra of patient for Guang, the air bag or water pocket of catheter leading section.
Before the urethra thickness of male differs, and the leading section of catheter enters bladder, it is necessary to through narrow prostate.
If catheter is meticulous, urine is easily discharged between urethra and the outer wall of catheter, pollutes bedding.If catheter is too
Slightly, then it is difficult through prostate, frequently results in intubation defeat.Clinically, sometimes under the cooperation of seal wire, it is also difficult to make catheter
Through prostate.
The innovation and creation of Application No. 200920027500.9 disclose a kind of guide wire catheter, and which includes seal wire and urethral catheterization
Pipe, is provided with seal wire in catheter.During use, first by seal wire insert catheter in, when catheter insert bladder after, then by seal wire from
Extract out in catheter.And the catheter that the innovation and creation of Application No. 201520867920.3 are disclosed then employ stiff guide wire and
The mode that soft seal wire coordinates, allows urinary catheter by lower urinary tract obstruction section caused by the diseases such as prostatic hyperplasia, urethral stricture.
It is also the common problem in Clinical practice of catheter that catheter is susceptible to block.Application No.
201310366414.1 innovation and creation disclose a kind of bladder irrigation blockage resisting catheter, and its anticlogging mode is in air bag
Outside sets drainage screen.The innovation and creation of Application No. 201320771549.1 disclose a kind of blockage resisting catheter, and which is provided with
One blockage resisting elastic pellet capsule, by extruding elastic pellet capsule, makes liquid in pipe backflow wash mouth of pipe clot open anti-blocking to realize
The purpose of plug.
On the other hand, the level pressure discharge of catheter is a research direction of catheter.Such as Application No.
201410146265.2, the technical scheme disclosed in 201521063715.8,201610198874.1 innovation and creation.They
Ultimate principle is：According to the pressure value of intravesical urine, as the foundation for opening catheter control valve.When the pressure of intravesical urine
After force value reaches the value of setting, control valve is automatically turned on, and urine is discharged.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of catheter, which easily not only can be inserted
Enter urethra and be fixed in urethra, the probability of urethral catheterization blockage can also be reduced.
To achieve these goals, technical scheme is as follows：A kind of catheter, including conduit and air bag, conduit
Leading section be provided with into urine hole, air bag is connected with the source of the gas of outside by gas passage, the conduit and gas passage split
Formula is arranged, and air bag is fixed on the leading section of gas passage, and gas passage is that a diameter is less than the body into urine hole aperture, and gas leads to
Road is located at the drain intracavity of conduit and can pass through into urine hole to pass the drainage lumens of conduit.
The gas passage of traditional catheter is opened on the side wall of catheter.And the gas passage of the application be one with lead
The tubule of the split type setting of urinary catheter, the leading section of tubule is air bag.During intubation, only the conduit of catheter need to be inserted urethra, and
Prostate need not be passed through.When the leading section of conduit reaches prostate, gas passage is inserted toward bladder direction, wears gas passage
Prostate is crossed, as gas passage is thinner, prostate can be easily threaded through.After the leading section of gas passage reaches bladder, give
Airbag aeration, then can be fixed on gas passage in urethra.Afterwards, gas passage and catheter are carried out in certain point solid
It is fixed, then catheter can be fixed in urethra.
When intravesical is full of urine, air bag is floated in urine.When patient moves, air bag can be being rocked in urine, band
Dynamic gas passage is rocked in catheter, it is possible to reduce the probability of urethral catheterization pipe choking.On the other hand, the direct handle of traditional catheter
Urine is derived from intravesical, i.e., urine is directly entered the conduit of catheter.And in the application, urine first flows through prostate, then enter
Enter the conduit of catheter, prostate has certain crown_interception in advance to obturator, can further reduce the general of urethral catheterization pipe choking
Rate.
Used as improvement, the conduit is provided with an arm, the oral area of arm have one for sealing rubber stopper, gas passage
Through rubber stopper.Rubber stopper is the fixing point of gas passage and catheter.Rubber is plugged with three effects：One is the mouth for sealing arm
Portion, two is to play a part of fixed gas passage, and three is to play a part of A/C and gas passage.
Used as improvement, one end that the oral area of the arm has a fixed cover, rubber stopper props up fixed cover.Fixed cover is enclosed within and props up
The oral area of pipe, prevents rubber stopper from being touched down.
Used as improvement, the gas passage has seal wire.Seal wire facilitates gas passage to pass through narrow prostate gap.
As improvement, water pocket on the conduit, is provided with, water pocket is connected with the water source of outside by fluid passage.Water pocket has
Two effects：One is to prevent urine from flowing out between urethra and urethral catheterization pipe outer wall, and two is to play the work for further fixing catheter
With.
Used as further improving, the fluid passage is one positioned at supravasal cavity.
As improvement, urethral catheterization groove on the outer surface of the air bag, is provided with, the outer surface of gas passage is also equipped with leading
Urine groove.Urethral catheterization groove is convenient to cause catheter by intravesical urine.
Used as further improving, the air bag is fixed with a load cell, and the afterbody of conduit is provided with electromagnetic valve, pressure measurement unit
Part is connected with externally-located controller, the unlatching of the pressure duty control solenoid valve that controller is measured according to load cell or pass
Close.The program realizes the level pressure discharge of urine.
Used as further improving, load cell is connected with externally-located controller by a transmission line, the transmission line
For seal wire.The transmission line of load cell is used by the program simultaneously as seal wire.
As further improving, water suction packing ring on the conduit, is provided with.Adsorptive pads are enclosed
The effect flowed out between urethra and urethral catheterization pipe outer wall.
In sum, the present invention has novel in design, easy to use, effect clear advantage.With traditional catheter phase
Than intubation is easily laborsaving, and is difficult plugging, moreover it is possible to prevent urine from polluting bedding after overflowing between urethra and urethral catheterization pipe outer wall.
