Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of bladder drainage drug infusion device.
Background technology
Irrigation of bladder is the interior topical medications method of bladder cavity commonly used clinically; Be mainly used in the postoperative chemoprophylaxis of tumor of bladder, the aspects such as irrigation of cystitis; Its method that adopts usually is the medicine of dilution to be passed through the disposable injection patient's of catheter intravesical, and medicine was kept 0.5～2 hour at intravesical.But adopt the weak point of this method to be, because medicine makes medicine in filling process, not possess persistence through the disposable injection patient's of catheter intravesical; Receive the restriction of patient's bladder capacity; Can medicine be excreted in a short time, shorten medicine in intravesical retention time, especially for patients such as interstitial cystitiss; More maybe because of the time of contact of mucous membrane of urinary bladder and medicine the too short drug effect that causes insufficient, thereby affect the treatment and cause the waste of medicine; Simultaneously because medicine passes through the disposable injection patient's of catheter intravesical; Make drug level high; In the preventative perfusion chemotherapy of bladder cancer, the high concentration chemotherapeutics is bigger to bladder irritation like this, possibly cause that mucous membrane of urinary bladder burns; Form chemical cystitis, symptoms such as frequent micturition, urgent micturition, dysurea and hematuria occur.
Summary of the invention
The objective of the invention is deficiency to prior art; A kind of bladder drainage drug infusion device is provided; It is simple in structure, and is easy to use, has both had the urethral catheterization function; Can continue as required again slowly to the intravesical dabbling drug, can improve the intravesical treatment of drug perfusion efficient, increase drug effect in time of bladder and continue to keep the intravesical drug level.
Technical scheme of the present invention is: a kind of bladder drainage drug infusion device, comprise the catheter that is provided with the location capsule, and said catheter is three lumens that are provided with the drainage lumens of urinating, water-injecting cavity, drug infusion chamber; Three chambeies of this catheter are independent separately, and the said drainage lumens of urinating is positioned at the catheter center, the upper end closed of said catheter; The sidewall of catheter upper end is provided with draining hole and communicates with the drainage lumens of urinating; The outlet that the catheter lower end surface is provided with the drainage lumens of urinating is communicated with urinary drainage bag, and said water-injecting cavity, drug infusion chamber are located at respectively in the catheter sidewall, and the water filling port of water-injecting cavity upper end communicates with the location capsule; The water injection hole of water-injecting cavity lower end connects the water filling interface; The water filling interface is provided with switch, and the medicine-pouring port of upper end, said drug infusion chamber runs through the catheter sidewall, and the medicine-pouring hole of lower end, drug infusion chamber connects the injection interface; Said injection interface is connected with the drug infusion pump of a scalable flow velocity through conduit, and an end of said drug infusion pump is connected with medicament canister.
Said water-injecting cavity and drug infusion chamber lay respectively at the drainage lumens both sides of urinating.
The internal diameter in said water-injecting cavity and drug infusion chamber is all less than the internal diameter of the drainage lumens of urinating.
Said water filling port is positioned at the below of draining hole, and the distance of this water filling port end face apart from the catheter upper end is greater than the distance of draining hole apart from catheter upper end end face.
Said medicine-pouring port is between draining hole and catheter upper end end face.
Said water injection hole and medicine-pouring hole are screwed hole, and said water filling interface and injection interface are threaded with water injection hole and medicine-pouring hole respectively.
Adopt technique scheme: with catheter upper end insertion patient's intravesical, it is external that the lower end is retained in the patient, and the location capsule together inserts patient's intravesical with the upper end of catheter; Because said catheter is three lumens that are provided with the drainage lumens of urinating, water-injecting cavity, drug infusion chamber; Three chambeies of this catheter are independent separately, make catheter when realizing urethral catheterization, carry out dabbling drug; And independent separately, can not interfere.Because the said drainage lumens of urinating is positioned at the catheter center; And the upper end closed of catheter; The sidewall of catheter upper end is provided with draining hole and communicates with the drainage lumens of urinating, and the outlet that the catheter lower end surface is provided with the drainage lumens of urinating is communicated with urinary drainage bag, makes the intravesical urine of patient can be in draining hole flows into the drainage lumens of urinating of catheter like this; Be discharged in the urinary drainage bag through the drainage lumens of urinating again, realized the function of urethral catheterization.Because said water-injecting cavity, drug infusion chamber are located at respectively in the catheter sidewall, wherein the water filling port of water-injecting cavity upper end communicates with the location capsule, and the water injection hole of water-injecting cavity lower end connects the water filling interface; The water filling interface is provided with switch, during use, opens the switch on the water filling interface; Through water-injecting cavity water filling in the capsule of location, the location capsule is heaved, when being close to opening of bladder, the location capsule after heaving can close switch; Stop water filling; Thereby make the location capsule after heaving both can play the effect of sealing opening of bladder, can locate catheter again, also can not cause sense of discomfort the patient; The medicine-pouring port of upper end, said drug infusion chamber runs through the catheter sidewall, and the medicine-pouring hole of lower end, drug infusion chamber connects the injection interface, and said injection interface is connected with the drug infusion pump of a scalable flow velocity through conduit; One end of said drug infusion pump is connected with medicament canister, and the medicine in the medicament canister can be flowed into earlier in the drug infusion pump, regulates and controls well behind the flow velocity through the drug infusion pump; Continue to be fed into patient's intravesical slowly through the drug infusion chamber again, thereby make patient's intravesical can keep two fun gi polysaccharides for a long time, no matter whether emptying of patient's bladder; Drug level can remain unchanged basically, compares with existing method for filling, and this device has not only increased the time of drug effect in bladder; Make the patient can accept the Drug therapy of longer time; Improve curative effect, avoided drug waste, and reduced the concentration of dabbling drug; Avoided bladder being caused stimulation, improved the safety of drug infusion because of the excessive concentration of dabbling drug.
Because said water injection hole and medicine-pouring hole are screwed hole, said water filling interface and injection interface are threaded with water injection hole and medicine-pouring hole respectively, are convenient to mounting or dismounting, and is easy to use.
This bladder drainage drug infusion device; Simple in structure, easy to use, both had the urethral catheterization function; Can continue as required again slowly to the intravesical dabbling drug; Effectively raise the efficient of intravesical treatment of drug perfusion, increased drug effect in time of bladder and continue to have kept the intravesical drug level, guaranteed therapeutic effect.
