Abstract
A urinary catheter capable of administering drug in a cavity with a one-way valve comprises a urine conduit, a drug injection conduit, a gasbag and a gasbag conduit which are arranged in parallel, wherein the front end of the urine conduit is provided with a urine leading-out hole, and the gasbag is communicated with the front end of the gasbag conduit after being arranged on the urine leading-out hole on the urine conduit. The urinary catheter is characterized in that a drug releasing hole is arranged on the dry injection conduit, and the tail end, namely the drug injection end of the drug injection conduit is provided with the one-way valve. Compared with the prior art, the urinary catheter has the advantages that medical solution can not flow back after using an injection to push dry to the drug injection conduit, and a convenient and effective treatment method is supplied for clinical doctors, suffering of patients during the treatment process is greatly lightened, and medical staffs and nursing staffs can conveniently and accurately operate according to the metering scales marks on the outer wall of the urinary catheter for preventing overdriving the urinary catheter and damaging bladder mucosas.
Description
Technical field
This utility model belongs to medical apparatus and instruments, but specifically is a kind of catheter that is provided with the intracavitary administration of check valve.
Background technology
One, the patient who needs urethral catheterization in the clinical treatment usually makes patient be difficult to tolerance because of catheter to the stimulation of mucous membrane of urethra and mucous membrane of urinary bladder: show as frequent sharply micturition desire, dysphoria, very painful, even bring out increased heart rate, hypertension, totally unfavorable to the recovery of patient's physical and mental health and disease.
Two, Chinese normal adult male urethra length is 20cm-22cm, adult female's urethra is about 4cm-6cm, the patient has the case that much needs urethral catheterization in therapeutic process, owing to do not have metering scale on traditional catheter, it is dark excessively that medical personnel often insert catheter in the clinical manipulation of implementing urethral catheterization to the patient easily, causes the mucous membrane of urinary bladder damage easily.
Three, because in the clinical use, catheter needs multiple dosing, injection catheter long term exposure vulnerable to pollution in air, dirts etc. may enter injection catheter by the injection catheter collar extension.
Summary of the invention
In order to overcome the deficiencies in the prior art, for treatment provides a kind of handled easily, make Therapeutic Method abundant, but can alleviate the catheter of the intracavitary administration that is provided with check valve of patient's misery.This utility model is by the following technical solutions:
But a kind of catheter that is provided with the intracavitary administration of check valve comprises urine conduit, injection catheter, air bag and balloon catheter; Described injection catheter, urine conduit and balloon catheter are arranged side by side; Described urine catheter proximal end is provided with the urine leadout hole, after air bag is located at the supravasal urine leadout hole of urine, and is communicated with the balloon catheter front end.Described injection catheter is provided with drug release hole; At the injection catheter tail end is that medicine-injecting end is provided with check valve.Use this structure, pushing away medicine behind injection catheter with syringe, medicinal liquid can not reflux.
Described drug release hole has a plurality of; All be provided with drug release hole at the air bag front and back position.
The position that is located at the drug release hole behind the air bag is, is 0.5～15cm apart from the size of air bag; The position that is located at the drug release hole before the air bag is, is 0.1～2cm apart from the size of air bag.The setting of described position is that have nothing in common with each other in the position according to man, woman and child's physiological characteristics setting.
Described injection catheter has one or more.
Described injection catheter has one, and the drug release hole that then is located at the air bag front and back is located on this injection catheter.
Described injection catheter has many, and the drug release hole branch that then is located at the air bag front and back is located on the different injection catheters.Many injection catheters evenly are located at urine conduit periphery side by side.
Described balloon catheter tail end is provided with the air bag valve.Be marked with scale at the urine conduit, described scale is located on the urine conduit outer wall.
Compared with prior art, the utlity model has following advantage:
One, use this structure, pushing away medicine behind injection catheter with syringe, medicinal liquid can not reflux.Because in the clinical use, catheter needs multiple dosing, injection catheter long term exposure vulnerable to pollution in air, dirts etc. may enter injection catheter by the injection catheter collar extension, use check valve to solve this problem, both sealed injection catheter, the medicinal liquid after the injection can not refluxed.
Two, this product adopts the design of three tube chambers, in original Foley catheter wall, add one or more infusion of drug pipe again, be opened on the outer drug release hole of urethral catheterization tube wall by it and implement the corresponding treatment measure to urethra and bladder intracavitary administration, for the clinician provides convenient effective Therapeutic Method, greatly alleviated the misery in the patient medical process.
Three, medical personnel can operate accurately and conveniently to reduce catheter according to the metering scale of catheter outer wall labelling and insert the dark mucous membrane of urinary bladder damage that causes.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
But a kind of catheter that is provided with the intracavitary administration of check valve comprises urine conduit 4, injection catheter 2, air bag 8 and balloon catheter 7; Described injection catheter 2, urine conduit 4 and balloon catheter 7 are arranged side by side; Described urine conduit 4 front ends are provided with urine leadout hole 5, after air bag 8 is located at urine leadout hole 5 on the urine conduit 4, and are communicated with balloon catheter 7 front ends.Described injection catheter 2 is provided with drug release hole 3; Be marked with scale at urine conduit 4.At the injection catheter tail end is that medicine-injecting end is provided with check valve 9.Described balloon catheter 7 tail ends are provided with air bag valve 6.
Described scale is located on the urine conduit outer wall.
Described drug release hole 3 has 2～12, establishes 1～2 before air bag, establishes 1～11 behind air bag.In this example, drug release hole is provided with 6, establishes 2 before air bag, establishes 4 behind air bag.In this example, described injection catheter has one.
