Abstract
The invention discloses a three-cavity catheter which comprises a catheter body. A drainage channel is formed in the catheter body. A drainage connector is connected to the tail end of the catheter body. A ball bag is arranged on the side face of the catheter body. The other side of the catheter body is provided with a first excretion drainage hole and a second excretion drainage hole. A developing strip is arranged on the outer side of the catheter body. The developing strip penetrates through the ball bag, and the length direction of the developing strip is the same as that of the catheter body. An air inflation channel is arranged in the catheter body. One end of the air inflation channel is communicated with the ball bag, and the other end of the air inflation channel is connected with an air inflation connector. A flushing channel is also arranged in the catheter body. One end of the flushing channel is provided with a flushing hole, and the other end of the flushing channel is provided with a flushing connector. In the structure, the position of the ball bag can be accurately positioned by observing the developing strip, and discomfort of a patient is prevented from being induced. By the adoption of the ball bag structure with one side face, the trigone of bladder and the excretion drainage holes will not be oppressed, and the excretion drainage effect is better. Meanwhile, flushing treatment can be carried out without replacing the catheter with a flushing pipe, and the pain of the patient can be relieved.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of catheter.
Background technology
Catheter, it is the pipeline made with natural rubber, silicone rubber or polrvinyl chloride, can through per urethram inserting bladder in case drainage of urine out, after catheter inserts bladder, there is an air bag to fix catheter near catheter head end and stay intravesical, and not easily deviate from, and drainage tube connects urinal collection urine.In the prior art, catheter is without telltale mark function, and after sacculus water-filling or inflation, balloon wall implants, accurately cannot locate balloon position, likely continue stimulate friction trigone of bladder and bring out inflammation, patient is occurred, and frequent micturition, urgent micturition, hypogastric region suppress swollen discomfort, and it is not thorough to urinate.In addition, after employing catheter excretion drain, often also bladder is cleaned, need catheter to be extracted rear insertion syringe pipe, extra misery can be caused to patient.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of catheter, accurately can locate the position of sacculus, avoids bringing out patient's discomfort, and integrated pre-washing function, without the need to repeatedly plugging.
In order to solve the problems of the technologies described above, a kind of three-cavity catheter of the present invention, comprise catheter main body, in catheter main body, there is drainage channel, catheter body ends is connected with flow sub, described catheter main body side is provided with sacculus, the catheter main body opposite side deviated from this sacculus is provided with first, second excretion conduction hole, there is outside catheter main body development bar, this development bar is through described sacculus and its length direction is consistent with catheter main body, filling channel is provided with in described catheter main body, this filling channel one end is communicated with sacculus, the other end is connected with the gas-charging connection being placed in catheter body exterior, also irrigation channel is provided with in described catheter main body, this irrigation channel one end has the flushing hole being arranged at catheter body front end portion, the other end is connected with flush-through connection.
As the improvement of technique scheme, described filling channel and irrigation channel are all arranged in catheter main body wall, and described gas-charging connection is connected with filling channel by inflated hose, and described flush-through connection is connected with irrigation channel by rinsing flexible pipe.
As the improvement of technique scheme, first, second excretion conduction hole described is respectively near the forward and backward two ends of sacculus.
As the improvement of technique scheme, described catheter body front end is provided with the thread eye that can pass for guide wires.
As the improvement of technique scheme, in described gas-charging connection, breather cheek valve is installed.In described flush-through connection, there is resilient plug
The invention has the beneficial effects as follows: in this three-cavity catheter structure, accurately can locate the position of sacculus by observing development bar, thus avoid bringing out patient's discomfort.On the other hand, adopt the balloon structure of single side face, balloon wall and trigone of bladder do not contacted or only has a little contact, for a long time catheter can be fixed on intravesical, can not oppress trigone of bladder and excretion conduction hole, urethral catheterization drainage effect is better.And, catheter main body is provided with irrigation channel, just can carries out Arthrocentesis without the need to being replaced by syringe pipe, being conducive to alleviating patient's misery.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is one of structural representation of the present invention;
Fig. 2 is structural representation two of the present invention;
Fig. 3 is sectional structure schematic diagram of the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of three-cavity catheter of the present invention, comprise catheter main body 1, there is in catheter main body 1 drainage channel 2, catheter main body 1 end is connected with flow sub 3, described catheter main body 1 side is provided with sacculus 4, the catheter main body opposite side deviated from this sacculus is provided with first, second excretion conduction hole 5, 6, there is outside catheter main body 1 development bar 7, this development bar 7 is through described sacculus 4 and its length direction is consistent with catheter main body, filling channel 8 is provided with in described catheter main body 1, this filling channel 8 one end is communicated with sacculus 4, the other end is connected with the gas-charging connection 9 being placed in catheter body exterior, irrigation channel 10 is also provided with in described catheter main body 1, this irrigation channel 10 one end has the flushing hole 11 being arranged at catheter main body 1 leading section, the other end is connected with flush-through connection 12.In this three-cavity catheter structure, accurately can locate the position of sacculus by observing development bar, thus avoid bringing out patient's discomfort.On the other hand, adopt the balloon structure of single side face, balloon wall and trigone of bladder do not contacted or only has a little contact, for a long time catheter can be fixed on intravesical, can not oppress trigone of bladder and excretion conduction hole, urethral catheterization drainage effect is better.And, catheter main body is provided with irrigation channel, just can carries out Arthrocentesis without the need to being replaced by syringe pipe, being conducive to alleviating patient's misery.
