Abstract

The utility model relates to a casing catheter which relates to a clinical care instrument, comprising an injecting tube, a urinary catheter and a core for the urinary catheter. The urinary catheter comprises a head, a body, a side hole, a sac bag and a water filling pipe, and the inner cavity of the urinary catheter is above the side hole (The side hole of the existing urinary catheter is below the side hole of the urinary catheter). The core for the urinary catheter comprises the head, a neck body and the handle, and the urinary catheter and the core for the urinary catheter are in removable sheath form connection. The injecting tube comprises the head, the body and the handle and is used to inject narcotic and lubricants into an urethral canal. The utility model has the advantages of simple structure and convenient operation, and the utility model can be used for a plurality of diseases and has not only the mechanical treatment action but also the drug treatment function.

Description

The bushing type urinary catheter

This utility model relates to medical apparatus and instruments, particularly catheter.

Catheter is operation and the treatment means that urology department is often implemented clinically, and in emergency case, carry out often, the acute urinary retention that causes as the senile prostatic hypertrophy, need race against time catheter is inserted the bladder urethral catheterization, remove patient's misery, so that lay a good foundation for later treatment, but, the catheter of soft system is difficult to insert bladder in this class patient, existing way is could insert soft catheter urethral catheterization after inserting urethral dilatation repeatedly with urethral probe made of iron earlier, or to insert a soft catheter from its intracavity again behind the hollow iron pipe insertion bladder, then iron pipe is pulled out and to be continued treatment by indwelling catheter, above-mentioned operation technique is not only loaded down with trivial details but also cause unnecessary misery to patient, insert this method of catheter again with urethral catheterization probe elder generation dilating urethra and increased the misery of inserting number of times, also increased simultaneously the damage of urethra, in addition, the another common drawback that it and iron pipe intracavity insert catheter is that the thickness of indwelling catheter is undesirable, because it is meticulous to insert catheter, therefore, frequently the urine that has is overflowed (latter more very) around catheter in continuing the urethral catheterization process, polluted bedding, soak patient's skin, giving patient, the clinical care treatment causes a lot of troubles.

The purpose of this utility model provides a kind of novel catheter, though it is a kind of soft catheter, but possesses the function of urethral probe, the drainage that machinery is not only arranged, but also can carry out Drug therapy, thus enlarged the therapeutical effect scope of catheter, can better finish operation clinically, reduce wound, for more sick people that plant remove misery.

This utility model is achieved in that the catheter of mainly making with rubber or other nontoxic high molecular polymer, and characteristics of the present utility model are made up of the urethral catheterization tube core of soft catheter and hard.The head of catheter is to be made by duroplasts or other hard material, the inner chamber degree of depth of catheter surpasses side opening urethral catheterization tube head inner chamber and is blind bag, be provided with the capsule bag that semipermeable membrane constitutes behind the side opening, and being provided with water injection pipe at the catheter end, the urethral catheterization tube core of soft catheter and hard is the sleeve type structure that can insert or extract out.

Description of drawings, Fig. 1 are a kind of enforcement side sketch maps of the present utility model.

Urethral catheterization tube head 1 links to each other with urethral catheterization body 4, nearly urethral catheterization body 4 places have a side opening 2 at least on urethral catheterization tube head 1, behind side opening 2, be provided with capsule bag 3, and there is water injection pipe 6 to communicate at urethral catheterization body 4 ends, catheter lumens 5 degree of depth surpass side opening 2, catheter core print 7 necks 8 bodies 9 can insert urethral catheterization lumen 5, and catheter core print 1 is crossed the top that side opening 2 reaches urethral catheterization tube head 1 inner chamber, and urethral catheterization tube core handle 10 stays outside the urethral catheterization lumen 5.

The utility model has the advantages that: simple in structure, easy to use, easy and simple to handle, purposes is wide, has reduced operation wound and misery, has enlarged indication, for more patient removes slight illness.

This utility model can be made the catheter of clinical employed various standard specificationss on demand.Earlier the urethral catheterization tube core is inserted catheter lumens 5 during operation, and make it to be " " type is convenient to urinary catheter with the physiology curvature that adapts to male urethra insertion in the 7 places bending of urethral catheterization tube core neck.Patient sets position and at first thin syringe is inserted the urethral injection anaesthetic, lubricant, hand-held routinely then urethral catheterization tube core handle 10 inserts intravesical with this utility model head body part, again the urethral catheterization tube core is extracted (because core is in catheter, therefore extract this process patient no pain, urethra also re-loss-free is hindered) get final product drain, treatment, according to injecting heterogeneity in the disease kind needs capsule bag 3, the liquid of composition, promptly play the urinary catheter fixation and play the Drug therapy effect again, as injecting hemorrhage in the prostatectomy postoperative patient capsule bag, can inject antitumor drug in the carcinoma patient capsule bag, can inject cicatrix softening agent (pressurization back capsule bag also can play the mechanical expansion effect) in patient's capsule bag of urethral stricture, have in patient's capsule bag of inflammation and can inject antibiotic medicine or the like.Reach the Drug therapy effect and can add electricity consumption importing treatment or the like by semipermeable membrane.

Claims

1, the bushing type urinary catheter mainly is to be made of catheter, feature of the present utility model is that said catheter is that urethral catheterization tube head 1 by hard material links to each other with the urethral catheterization body 4 of soft material, and nearly urethral catheterization body 4 places have side opening 2 and communicate with catheter lumens 5 on urethral catheterization tube head 1; The hard urethral catheterization tube core that can freely insert or extract out is arranged in catheter lumens 5, when the state of insertion, catheter core print 7 enters the inner chamber of urethral catheterization tube head 1 and seals side opening 2, tail end at catheter core body 9 has urethral catheterization tube core handle 10, is provided with the capsule bag 3 that semipermeable membrane makes and surrounds urethral catheterization bodys 4 and have water injection pipe 6 to communicate with it in urethral catheterization body 4 ends behind side opening 2.

2, according to the described bushing type urinary catheter of claim 1, it is characterized in that described urethral catheterization tube head 1 is that arc head garden is tapered, its inner chamber is blind bag.

3,, it is characterized in that described side opening 2 has one at least according to the described bushing type urinary catheter of claim 1.
