Description
Technical field
The utility model relates to a kind of medical instruments, and in particular to a kind of irrigation of bladder device.
Background technique
Irrigation bladder treatment (hereinafter referred to as irrigation of bladder) is one of the important means for the treatment of bladder cancer, and dabbling drug can
It is divided into immunization therapy (BCG vaccine) and chemotherapy (such as gemcitabine, epirubicin) two major classes, is usually used in per urethra bladder
The postoperative patient of tumor resection, it acts as the tumour cells for killing remaining in bladder to make the life better to prevent tumor recurrence
Quality extends patient's service life.Irrigation of bladder at present is to be injected prepared drug solution (about 50ml) using three-cavity catheter
Into bladder, so that drug is retained 30-60min (the reservation infusion time of different pharmaceutical slightly has difference) in bladder, suffer from during perfusion
Person need to be interrupted changing position, and (such as dorsal position 10 minutes, left lateral position 15min, right lateral position 15min, prone position 10min stand
Position 10min), basic goal be allow drug and each wall of bladder come into full contact with (be usually described as left side wall, right side wall, trigonum, after
Wall, roof, bladder neck etc.).After reaching infusion time, drug can be released by urinary catheter, pull out or continue according to the state of an illness
Retain urinary catheter, and patient is advised to drink more water in right amount, it is diligent to urinate.
Three conventional chamber urinary catheter structures include: a- water inlet, and b- water outlet, c- bladder port, c itself is a check valve
Door is additionally provided with a mouthfuls and b mouthfuls of control of switch.Specific irrigation of bladder operating process at present are as follows: 1. advise patient's horizontal position, disappear
Indwelling three-cavity catheter after poison (saline injection 15ml fixes water pocket at c mouthfuls, if indwelling in advance has a urinary catheter, directly into
Row step 2)；2. opening valve at b mouthfuls, the valve is closed after urine is drained；3. prepared drug is slowly pushed away by a mouthfuls
Into after bladder, valve at a mouthfuls is closed；4. patient is advised to be interrupted changing position (it has been observed that specific position and time are according to drug and disease
Depending on feelings)；5. opening valve at b mouthfuls, dabbling drug is drained, pulls out or continue indwelling catheter according to the state of an illness.
Above-mentioned irrigation of bladder scheme is easy to operate, low in cost, is generally applied by current all medical institutions both at home and abroad.
However the program also suffers from certain drawbacks, and it is main as follows: if 1. entire patients are out of condition, it is not easy to multiple changing position,
Then it is relatively inaccessible to the purpose of perfusion；2. adverse reaction can occur for all drugs irrigation of bladder, such as chemical cystitis (urine
Frequently, urgent urination, blood urine etc.), even septicemia can occur for perfusion BCG vaccine person, except epirubicin infusion time is 30-40min,
Remaining drug is required to perfusion 60min, and the time is longer, and adverse reaction odds and severity may be higher.
Utility model content
Technical problem to be solved in the utility model is existing irrigation of bladder for the repeatedly transformation of the big needs of contact area
Position and it is inconvenient, while infusion time length be easy to cause adverse reaction, should its purpose is to provide a kind of irrigation of bladder device
Device is by being changed to plume contact for pouring liquid contact, when being capable of increasing contact area and do not have to changing position, while being perfused
Between greatly shorten.
The utility model is achieved through the following technical solutions:
A kind of irrigation of bladder device, including spraying device and the three-cavity catheter connecting with spraying device, three chamber is led
Several groups spray holes group is provided on the drainage tube of urinary catheter, spray holes group is connected to three-cavity catheter outside, and spray holes group
It is connected to the water inlet of three-cavity catheter, the air bag of three-cavity catheter is arranged between spray holes group.Current irrigation of bladder
Mode be all by the way that the liquid medicine of liquid is filled into patient's bladder by three-cavity catheter, it is this by liquid medicine use liquid and wing
The mode of Guang wall contact, due to liquid liquid medicine finite volume itself, contact area is also limited, so patient is needed repeatedly to convert
Position and cause inconvenience, the patient of especially body inconvenience is more troublesome, at the same liquid perfusion mode to consider patient's wing
Guang bears situation, and impact is big, needs slowly to carry out, and causes that time-consuming, and it is intermediate also to pass through multiple postural change, just more
Add and extend infusion time, increases adverse reaction rate, the device for casting of this programme design, by liquid medicine water using spray
Mist device forms mist, big with the contact area of bladder wall surface since liquid medicine area is big after by spraying in spirt bladder, uses
Same position can reach therapeutic effect, and patient is not required to changing position, reduce the trouble of patient, while Sprayable is to trouble
The bladder impact of person is small, can persistently be irrigated, time-consuming short, reduces adverse reaction rate.
In order to increase area when injection, and prevent blind area, spray holes group will be designed as a variety of, and optimal selection is
Two groups, air bag is arranged between two groups of spray holes groups, can either realize that liquid medically deposits in bladder, and can protect
Contact area is demonstrate,proved, and every group of spray holes group includes several spray holes in spray holes group, and the spray holes of every group of spray holes group
It is arranged on the same periphery of drainage tube.It is equidistant between adjacent spray holes in every group of spray holes group.Spray holes group
In wherein the spray holes of one group of spray holes group respectively correspond and be arranged between the adjacent spray holes of another group of spray holes group.Exist in this way
When being sprayed, it is capable of increasing spray effect, non-blind area generates.
Since the entrance of three-cavity catheter is all that silica gel has elasticity, spraying device and three-cavity catheter are inconvenient directly solid
It is fixed, so be provided with attachment device between spraying device and three-cavity catheter, and attachment device simultaneously with spraying device and three
The water inlet of chamber catheter is fixed.Thread segment, and the spiral shell are provided on outer wall of the attachment device towards one end of spraying device
Line section is screwed in be formed in spraying device and be fixed, and fixation is more stable by way of spiral, and attachment device is towards three-cavity catheter
One end the tapered structure of outer wall, and pyramidal structure is inserted into water inlet and forms fixation, energy after such pyramidal structure insertion
It enough prevents from falling off.
The three-cavity catheter of improvement is in balloon ends, away from the spray for respectively having a circle spray holes to be formed at balloon ends about 0.5cm
Why mist hole group is respectively to have a circle in balloon ends, is in order to avoid after air bag is inflated, if drug is simply by urinary catheter top
End sprinkling, then the bladder wall below air bag is then herbal sprinkling blind area, a circle aperture is opened below air bag, then can solve this
A problem, but need to give urinary catheter inward a distance (1cm or so) to guarantee that drug passes through gas before should be noted that sprinkling drug
Small hole injection below capsule is into bladder.
The utility model compared with prior art, has the following advantages and benefits: the device is by filling liquid
Note contact is changed to plume contact, improves experience of the patient in filling process, is capable of increasing contact area and does not have to transformation body
Position, enhances perfusion curative effect, while infusion time greatly shortens, reduces adverse reaction rate.
