Description

Bladder perfusion closed type adapter

Technical Field

The utility model relates to a bladder perfusion closed type adapter, and belongs to the technical field of medical instruments.

Background

Worldwide, the incidence rate of bladder cancer is 9 th of malignant tumors, and the incidence rate of bladder cancer is 7 th of male rank, which accounts for the first malignant tumors of the urinary system, and can occur at any age, even children are possible. Among bladder cancers, Non-muscle invasive bladder cancer (NMIBC) accounts for about 75% to 85%, and usually is treated by transurethral cystocele (turbo), photodynamic, and transurethral laser surgery. Has good clinical curative effect and is used as the current gold standard for clinically treating bladder cancer. The TURBT combined postoperative bladder perfusion chemotherapy is more and more widely applied, and TUR-BT combined bladder perfusion therapy becomes the first choice for treating superficial bladder cancer.

Glandular cystitis is a special type of proliferative and biochemical pathological changes of the mucous membrane of the bladder, and the etiology and pathogenesis of the cystitis are still not completely clear at present. The incidence rate of the disease is obviously increased in recent years, and a uniform specific treatment method for the disease is not available. Most scholars are currently inclined to adopt a superficial bladder cancer treatment regimen: electrically cutting pathological tissues through urethra and combining long-term chemotherapy medicine bladder perfusion for many times after operation.

The bladder perfusion is that a nursing staff injects one or more chemotherapy drugs or immune preparations with a certain dosage into the bladder of a patient through a catheter and keeps the chemotherapy drugs for a period of time, namely, the chemotherapy drugs directly act on the affected part of the bladder by adopting an intravesical perfusion method, and the residual microscopic malignant tumor focus, the fallen malignant tumor cells, the in-situ cancer or the precancerous lesion and the like which are invisible to the naked eye in the bladder after operation are killed by utilizing the cytotoxicity function of the chemotherapy drugs, so that the progress of the bladder cancer and the recurrence and metastasis of the bladder cancer are slowed down and prevented, and the purposes of removing the tumor cells and preventing the recurrence are achieved.

During bladder perfusion treatment, adopt syringe and catheter drainage department lug connection usually, because the external diameter of syringe nipple is less than the internal diameter of standard catheter far away, the two links up loosely, drops easily, and liquid leaks, and this not only causes the liquid medicine extravagant and dose inaccuracy of dosing, but also can cause the harm because medicine pollutes patient and medical personnel's skin. Some medical staff use the syringe needle directly to insert the ureter from the skin in clinic, carry out the injection and use medicine, greatly increased the danger of needle stick injury, occupation exposure. At present, no suitable joint for direct use or the condition that the existing joint structure is complicated and inconvenient for clinical use exists clinically.

It is reported in the literature that immediate removal of the urinary catheter after bladder perfusion is more likely to cause bladder irritation in patients than removal of the urinary catheter after perfusion.

Preferably, connect II including interface end I and interface end II, interface end I is located interface end II insidely, two unification dual interfaces, can carry out the double passage, carry out the bladder and perfuse the back, avoided extracting the crossover sub after, insert the chemotherapy medicine that this process of urine bag connector nipple arouses and leak, cause the pollution.

Preferably, the inner diameter of the mouth-piece end I is 4mm, the inner diameter of the mouth-piece end II is 10mm, the mouth-piece end I is in butt joint with a needleless injector nipple filled with chemotherapeutic drugs, and the mouth-piece end II is in butt joint with a urine bag joint nipple.

Preferably, joint I and joint II are integrated into one piece design, wholly adopt medical grade PVC material, and overall structure is simple, easily realizes.

Preferably, the cross valve connecting joint I and the joint II are provided with a transverse pull rod switch, so that one-hand operation can be realized.

Compared with the prior art, the utility model has the beneficial effects that: joint I connects multiplicable frictional force for screw thread formula round platform, reduce the risk that drops, cross valve switch plays anti palirrhea effect, prevent the retrograde infection, the syringe nipple replaces the syringe needle, avoid the occupation that the needle stick wound arouses to expose, can prevent that syringe and pipe diameter are inconsistent to arouse the liquid medicine seepage, spray and arouse environmental pollution, and clinical staff's skin safety, the extravagant liquid medicine has been prevented, accurate dosing, use manpower sparingly, provide reliable assurance for the treatment that the bladder perfused, two unification dual interfaces, can carry out the dual-channel, carry out the bladder and perfuse the back, avoided pulling out behind the crossover sub, insert the outer hourglass of chemotherapy medicine that this process of urine bag connector nipple arouses, cause the pollution, overall structure is simple, and is safe in utilization, reliability, the characteristics of easy production.
