The technical problem solved by the utility model is implemented by the following technical solutions:

A kind of novel urethra topical remedy adjuvant treatment catheter, including drainage channel tube body, and open in drainage channel Irrigation channel and air bag passage in tube body wall, air bag passage are connected to the air bag for playing fixed catheter, which is characterized in that A drug channel is also provided in the drainage channel tube body wall, there is connector in one end of the drug channel by piping connection, The connector can be connected to the mating connection of external equipments, the other ends of drug channel such as syringes with tube screen hole body, the pipe Shape sieve pore body is opened for one section and is provided on the cannulated cavity in drainage channel tube body wall, the lateral wall of the cannulated cavity Multiple sieve pores being connected to exterior space.

For the utility model, the tube screen hole body is set to bulb urethrae position or the membranous part of urethra of drainage channel tube body Position or urethra penis sponge body region.

Working principle: after drug channel is connect by connector with external equipment, the drug of external equipment can be logical by drug Road is delivered in the cavity of tube screen hole body, then is flowed out into human urethra by the sieve pore of chamber outer wall, thus real Now to the drug therapy of urethra.

The utility model has the advantages that the utility model can not only give full play to the effect of urethra topical remedy, it can also be according to difference Treatment require to connect different instrument, bring great convenience to patient's treatment；Meanwhile the utility model not only can only be used to Urethral stricture disease can also be applied to other and need the disease of localized urethral medication；The utility model can not only make medicine Object comes into full contact with urethra, and the action time of adjustable drug and urethra lesion mucous membrane, guarantees that drug plays maximum efficiency, Also facilitate patient in the preoperative, it is postoperative and discharge after use, while can greatly reduce patient pain and repeatedly urethra behaviour Make.

Specific embodiment

Below by drawings and examples, the technical solution of the utility model is described in further detail.

Referring to shown in attached drawing 1-3, a kind of novel urethra topical remedy assists in the treatment of catheter, including drainage channel tube body 1, And it opens in irrigation channel 3 and air bag passage 2 in drainage channel tube body wall, air bag passage and the gas for playing fixed catheter Capsule is connected to (not shown), it is characterised in that a drug channel 5, the drug are also provided in the drainage channel tube body wall There is connector 4 in the one end in channel by piping connection, the connector can with the mating connection of external equipments such as syringe, drug channel it is another One end is connected to tube screen hole body 6, and the tube screen hole body is one section and opens in the cannulated chamber in drainage channel tube body wall Body is provided with multiple sieve pores 7 being connected to exterior space on the lateral wall of the cannulated cavity.

The utility model be current two-chamber or three chambers (as shown in the picture, including drainage channel, air bag passage, rinse it is logical Three chamber of road, two-chamber then do not include irrigation channel) on the basis of catheter, increase a drug channel and one section of tube screen hole body, it manages Shape sieve pore body is a tiny tubular cavity, has a certain number of small sieve pores with mucous membrane of urethra contact surface, is that drug enters The channel that urethra plays a role.The minim channel of tube screen hole body has no effect on its slickness, in order to the common portion of ankylurethria Position matches, and can design three kinds of different tube screen hole bodies and be placed in bulb urethrae position, the membranous part of urethra, urethra corpora cavernosa penis Cloth.Drug channel one end tube screen hole body communicates, and the other end can be connected different instruments by connector and carry out different periods Treatment, such as directly can inject drug with syringe, micro computer infusion pump can be connected or microelectronics pump, it is required according to different treatments It is adjusted, feasible locally injecting treatment, long-term micro continued treatment or long periods treatment.According to patient in art Before, in art, it is postoperative and discharge after drug therapy selection be suitble to connection instrument.

The effect and working principle of each component: drainage channel drains liquid in bladder；The air bag being connected to air bag passage exists Play fixed catheter after inflation；Irrigation channel is mainly used to bladder irrigation and perfusion；Connector can connect syringe, Infusion apparatus, microelectronics pump etc., connect different equipment as needed；Drug channel is drug from outer into tube screen hole body Channel；Tube screen hole body, which is used to discharge drug, to be allowed to come into full contact with mucous membrane of urethra.In simple terms, according to different treatment need It asks, under the effect of different external connection instrument, drug enters tube screen hole body by drug channel and uniformly discharges and mucous membrane of urethra surface, Play its effect.

During use, it such as needs to treat injection of medicine in urethra, then infuses connector and external drug Enter equipment such as syringe to connect, drug is inputted in drug channel by infusion of medicine equipment and reaches tube screen hole body, then It is reached in urethra by the sieve pore of tube screen hole body, urethra inner membrance is treated.

The utility model can not only give full play to the effect of urethra topical remedy, can also be required according to different treatments Different instruments is connected, is brought great convenience to patient's treatment；Meanwhile the utility model not only can only be used to ankylurethria disease Disease can also be applied to other and need the disease of localized urethral medication；The utility model can not only be such that drug fills with urethra Tap touching, and the action time of adjustable drug and urethra lesion mucous membrane guarantee that drug plays maximum efficiency, also facilitate patient In the preoperative, postoperative and discharge after use, while can greatly reduce patient pain and repeatedly urethra operation.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.This The technical staff of industry is not departing from the spirit of the present invention it should be appreciated that the present utility model is not limited to the above embodiments Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed In range.The protection scope of the requires of the utility model is defined by the appending claims and its equivalent thereof.
