Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of new curved surface porous urinary catheter specifically.
Background technology
Catheter, be with pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), can be through per urethram inserting
Bladder comes out so as to drainage of urine, after catheter insertion bladder, has an air bag to fix catheter close to catheter head end and stays in
In bladder, and it is not easy, and drainage tube connection urinal collects urine.
Catheter can be divided into according to the difference of structure：Single-chamber standard type catheter, single-chamber plum blossom head dummy catheter, two-chamber mark
Pseudotype catheter, three chamber standard type catheters etc., the also different but main effect of the catheter purposes of different structure：1. it is urine
Retention patient drains urine with such as Postoperative and anesthesia (smooth muscle of bladder paralysis) that palliates the agonizing sufferings；2. clinical diagnosis is assisted such as to stay
Unpolluted Urine specimens are taken to make Bacteria Culture (such as pyelonephritis)；Measure bladder capacity pressure and check residual urine；Urinated
Road or cystography etc.；Avoid accidentally injuring in operation 3. pelvic organs operation consent is patient's export urine empty bladder.
Clinically most commonly used catheter is three-cavity catheter, main function：Urine is released for retention of urine patient, with
Palliate the agonizing sufferings；Urine specimen makees Bacteria Culture in collection bladder；For rescue shock or urgent patient, accurate recording urine volume, proportion,
Understand oliguresis or anuria reason, determine residual urine volume, bladder capacity and cystometry, inject contrast agent, bladder irrigation, detection urine
Road whether there is narrow and pelvic organ Preoperative Method；Treatment of drug perfusion is carried out to bladder by catheter；Carry out bladder chemotherapy etc..
The disease in the urological system Post operation such as prostatectomy in addition, three-cavity catheter is particularly suitable for use in, to promote bladder
The recovery of function and the healing of otch carry out indwelling urinary catheterization.But usually can catheter after current three-cavity catheter indwelling
The problem of blocking, this be due to Postoperative Residual some fine tissue fragments or clot be adsorbed in catheter head end opening place
Cause, need clinician to be constantly rinsed to dredge catheter afterwards, expend more manpower and material resources.
Chinese patent literature：CN201420480142.8, applying date 2014.08.21, patent name are：A kind of bladder punching
Wash formula three-cavity catheter.Disclose a kind of bladder irrigation formula three-cavity catheter, including drain branch pipe, water filling branch pipe and injection branch
Pipe, the end of injection branch pipe connect a joint with public Rule structure end and female Luer structure end, the public Shandong of its center tap
You are connected at structure end with the end of injection branch pipe.When being infused to injection branch pipe, the female Luer structure end of joint, nothing can be directly connected to
Public Rule structure end of pin transfusion device；Or the female Luer structure end connection of joint can carry out public Rule structure of good fortune infusion connector
End, the female Luer structure end that can carry out good fortune infusion connector reconnect public Rule structure end of no-needle transfusion device.
A kind of bladder irrigation formula three-cavity catheter of above-mentioned patent document, connecting one using the end of injection branch pipe has
Public Rule structure end and the joint at female Luer structure end, public Rule structure end connector are connected with the end of injection branch pipe, female Luer
Structure end connector connection no-needle transfusion device, public Rule structure end that good fortune infusion connector can be carried out, the female Luer of good fortune infusion connector can be carried out
Structure end reconnect no-needle transfusion device public Rule structure end, so as to avoid medical personnel directly insert the needle into injection branch pipe and
Error inserts the needle into water filling branch pipe.But on one kind bladder inner tissue fragment or clot etc. can be made to be not easy adsorbed close urethral catheterization
Tube wall, the generation of urethral catheterization blockage is greatly reduced, can be effectively by retention in the intravesical urine ejection of patient, mitigation patient suffering
While also reduce a kind of new curved surface porous urinary catheter of working doctor amount at present then without the report of correlation.
In summary, needing one kind badly can make bladder inner tissue fragment or clot etc. be not easy adsorbed close urethral catheterization tube wall, greatly
The generation of urethral catheterization blockage is reduced, can be effectively by retention while the intravesical urine ejection of patient, mitigation patient suffering
Reduce a kind of new curved surface porous urinary catheter of working doctor amount.
The content of the invention
The purpose of the present invention is can to take the deficiencies in the prior art, there is provided one kind can make bladder inner tissue fragment or clot etc. no
Easy adsorbed close urethral catheterization tube wall, greatly reduces the generation of urethral catheterization blockage, effectively can arrange retention in the intravesical urine of patient
Go out, a kind of new curved surface porous urinary catheter of working doctor amount is also reduced while mitigating patient suffering.
To achieve the above object, the present invention adopts the technical scheme that：

Pipe, when urethral catheterization tube body carries out urethral catheterization, drainage lumens opening is connected on medical drainage bag, so as to carry out drawing for urine
Flow and collect；Flushing chamber on the left of drainage lumens is noted medical saline by flush pipe by using syringe when rinsing
Inject and be rinsed in patient's bladder, may be such that the intravesical residual tissue pieces of patient or clot are diluted, then pass through note
Emitter extracts the physiological saline in patient's bladder out, can complete the flushing to patient's bladder；The head end of urethral catheterization tube body is song
Face structure, reduce urethral catheterization sense body and enter the intravesical resistance of patient, reduce contact pressure of the catheter head end with patient tissue
Power, mitigate the pain of patient；The rubber stopper that water-injecting cavity opening is provided with can prevent from injecting the water outflow in water pocket, ensure water pocket
Catheter body head position can be caused to be fixed in patient's bladder, situation about will not slide.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise without departing from the principles of the invention, can also make some improvement and supplement, and these are improved and supplement also should be regarded as
Protection scope of the present invention.
