Description
Technical field：
A kind of bladder heat perfusion apparatus is the utility model is related to, more particularly to a kind of bladder heat perfusion circulation conduit.
Background technology：
Irrigation of bladder is clinically topical medications method in common bladder cavity, is mainly used for the postoperative of tumor of bladder
The irrigation etc. of chemoprophylaxis, cystitis, the method for its generally use is that diluted medicine is passed through catheter one
In the bladder of secondary property injection patient, and make medicine retain in bladder 0.5~2 it is small when.But shortcoming in this way
It is, since medicine is disposably injected in the bladder of patient by catheter, medicine is not possessed continuation in filling process,
Limited by patient's bladder capacity, medicine can be excreted in a short time, shorten medicine in intravesical retention time, especially
It is for patients such as interstitial cystitis, is more likely to cause drug effect not because the time of contact of mucous membrane of urinary bladder and medicine is too short
Fully, so as to affect the treatment and cause the waste of medicine, simultaneously because medicine disposably injects the bladder of patient by catheter
It is interior so that drug concentration is high, so in the preventative perfusion chemotherapy of carcinoma of urinary bladder, high concentration chemotherapeutics to bladder irritation compared with
Greatly, mucous membrane of urinary bladder may be caused to burn, forms chemical cystitis, the symptoms such as frequent micturition, urgent urination, odynuria and blood urine occur.
Utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies of the prior art and provide a kind of simple in structure, just
In carrying, the efficiency of intravesical drug perfusion therapy can be improved, increases drug effect in the time of bladder and persistently keeps wing
The bladder heat perfusion circulation conduit of drug concentration in Guang.
The technical solution of the utility model is：A kind of bladder heat perfusion circulation conduit, including catheter, it is characterized in that：Institute
It is three lumens for being provided with exhaust chamber, admission chamber and venting cavity to state catheter, and the exhaust chamber, admission chamber and venting cavity are mutual
Independent, the upper end of the catheter seals to form sealed end, and by be disposed with the catheter of sealed end down inlet opening,
Outage and air bag, are provided with spacing, the catheter is by the gas between the sealed end, inlet opening, outage and air bag
Capsule extend downwardly and isolate the drain pipe being connected with exhaust chamber, the inlet tube being connected with admission chamber, be connected with venting cavity it is logical
Tracheae, the connection of the inlet opening and admission chamber, the outage are connected with exhaust chamber, and the air bag is connected with venting cavity.
From for 0.3-0.7cm between the air bag and outage, the spacing between the outage and inlet opening is
4-6cm, the spacing between the inlet opening and sealed end are 0.3-0.5cm.
The inlet opening and outage are at least two, and are set around catheter.The inlet tube and feed liquor and
Heating unit connects, and the drain pipe is connected with waste collecting device, and the snorkel is connected with inlet duct.
The beneficial effects of the utility model are：
1st, the utility model is realized by setting inlet opening, outage and the position of air bag and extends catheter in bladder
Length, solves the problems, such as that the prior art is undesirable to irrigation of bladder effect.
2nd, the utility model extends the distance between length and inlet opening, outage of catheter, is arranged on inlet opening
The top of bladder, is conducive to contact of the medicine with bladder inner wall, improves therapeutic effect, while outage is arranged on the bottom of bladder
Portion, discharging operation can also be carried out while playing urination to the medicine of injection.
3rd, interval is provided between the utility model inlet opening and sealed end, plays the role of buffering, is prevented because of high-pressure medicine
Liquid is uncomfortable caused by impacting bladder to patient.
4th, the utility model inlet opening is at least two, and is set around catheter, enables the liquid of ejection uniform
It is sprayed onto on bladder inner wall, then liquid flows to fundus of bladder portion along under bladder inner wall, is flowed out through outage.
5th, the utility model and outage are at least two, and are set around catheter, by increasing capacitance it is possible to increase liquid in bladder
The rate of outflow, also effectively prevents from blocking.
Brief description of the drawings：
Fig. 1 is the structure diagram of bladder heat perfusion circulation conduit.
Fig. 2 uses structure diagram for bladder heat perfusion circulation conduit.
Embodiment：
Embodiment：Referring to Fig. 1 and Fig. 2, in figure, 1- catheters, 2- sealed ends, 3- inlet openings, 4- outages, 5- air bags,
6- drain pipes, 7- inlet tubes, 8- snorkels, 9- bladders.
Bladder heat perfusion circulation conduit, including catheter 1, catheter 1 are to be provided with exhaust chamber, admission chamber and venting cavity
Three lumens, and exhaust chamber, admission chamber and venting cavity are separate, the upper end of catheter 1 seals to form sealed end 2, and by sealing
End 2 catheter 1 down on be disposed with a determining deviation be distributed inlet opening 3, outage 4 and air bag 5, catheter 1 by
Air bag 5 extends downwardly and isolates the drain pipe 6 being connected with exhaust chamber, the inlet tube being connected with admission chamber 7, is connected with venting cavity
Snorkel 8, the connection of inlet opening 3 and admission chamber, outage 4 is connected with exhaust chamber, and air bag 5 is connected with venting cavity.
