Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of novel curved surface porous urinary catheter.
Background technique
Catheter can be per urethram inserted into pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC)
Bladder comes out so as to drainage of urine, after catheter is inserted into bladder, has the fixed catheter of an air bag to stay in close to catheter head end
It in bladder, and 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 catheter purposes of different structure is also different, but main effect: 1. be 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)；It measures bladder capacity pressure and checks residual urine；It is urinated
Road or cystography etc.；3. pelvic organs operation consent is that patient's export urine empty bladder avoids accidentally injuring in operation.
Clinically most commonly used catheter is three-cavity catheter, and main function: releasing urine for retention of urine patient, with
It palliates the agonizing sufferings；Urine specimen makees Bacteria Culture in acquisition bladder；For rescue shock or urgent patient, accurate recording urine volume, specific gravity,
Understand oliguresis or anuria reason, measure residual urine volume, bladder capacity and cystometry, injects contrast agent, bladder irrigation, detection urine
Whether there is or not narrow and pelvic organ Preoperative Methods in road；Treatment of drug perfusion is carried out to bladder by catheter；Carry out bladder chemotherapy etc..
In addition, after three-cavity catheter is particularly suitable for the operation of the disease in the urological systems such as prostatectomy, to promote bladder
The recovery of function and the healing of notch carry out indwelling urinary catheterization.But it usually can catheter after current three-cavity catheter indwelling
The problem of blocking, this is because some fine tissue fragments or clot of Postoperative Residual are adsorbed in catheter head end opening place
It causes, needs clinician to be constantly rinsed to dredge catheter later, expend more manpower and material resources.
A kind of Chinese patent literature: CN201420480142.8, applying date 2014.08.21, patent name are as follows: 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 connector with public Rule structure end and female Luer structure end, the public Shandong of center tap
You connect at structure end with the end of injection branch pipe.When being infused to injection branch pipe, the female Luer structure end of connector can be directly connected to nothing
Public Rule structure end of needle infusion apparatus；Or the female Luer structure end connection of connector 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 patent document, connecting one using the end of injection branch pipe has
The connector at public Rule structure end and female Luer structure end, public Rule structure end connector are connect with the end of injection branch pipe, female Luer
Structure end connector connection no-needle transfusion device, the public Rule structure end that can carry out good fortune infusion connector, can carry out the female Luer of good fortune infusion connector
Structure end reconnect no-needle transfusion device public Rule structure end, thus avoid medical staff directly insert the needle into injection branch pipe and
Fault inserts the needle into water filling branch pipe.But bladder inner tissue fragment or clot etc. can be made to be not easy adsorbed close urethral catheterization about one kind
Tube wall greatly reduces the generation of urethral catheterization blockage, and effectively retention can be discharged in the intravesical urine of patient, mitigate patient suffering
While also reduce a kind of novel curved surface porous urinary catheter of doctor's workload at present then without relevant report.
Bladder inner tissue fragment or clot etc. can be made to be not easy adsorbed close urethral catheterization tube wall in conclusion needing one kind, greatly
The generation of urethral catheterization blockage is reduced, effectively retention can be discharged in the intravesical urine of patient, while mitigating patient suffering
Reduce a kind of novel curved surface porous urinary catheter of doctor's workload.
