the utility model provides a two gasbag two-chamber latex catheter, including the catheter body, the catheter body includes gasbag chamber and fixed gasbag, gasbag chamber and fixed gasbag intercommunication, the catheter body is still including buffering gasbag, buffering gasbag sets up in stretching into end terminal surface of catheter body to communicate with gasbag chamber, through gasbag chamber aerifys to buffering gasbag, makes the end terminal surface that stretches into of catheter body forms the buffering gasbag after the inflation.

Further, an air bag cavity opening is formed in the extending end of the catheter body and communicated with the air bag cavity.

Furthermore, the expanded volume and the wall thickness of the buffer air bag are both smaller than those of the fixed air bag.

Further, the post-inflation volume of the cushion bladder is 1/3-1/2 of the post-inflation volume of the fixed bladder.

Further, the thickness of the wall of the buffer air bag is 1/3-1/2 of the thickness of the wall of the fixed air bag.

Further, the catheter body also comprises a urethral catheterization cavity, the extending end of the catheter body is provided with a urethral catheterization opening, the extending end is provided with a urethral catheterization cavity opening, and the urethral catheterization opening and the urethral catheterization cavity opening are communicated with the urethral catheterization cavity.

Further, the distance between the urethral catheterization opening and the end face of the extending end of the urethral catheter body is 3.5-5 cm.

Further, the urethral catheterization cavity and the air sac cavity are arranged in parallel.

Further, the outer wall of the catheter body is provided with scales.

The utility model provides a two gasbag two-chamber latex catheter, compared with the prior art, its beneficial effect is:

the utility model provides a two gasbag two-chamber latex catheter, through set up the less buffering gasbag of volume at the catheter front end, can make stretching into of catheter body end volume increase after aerifing the inflation, the buffering gasbag produces deformation easily when contacting with the bladder inner wall, and then has improved the area of contact of catheter body and bladder, makes both be face-to-face contact, and traditional catheter point-end and bladder that compare are point-to-face contact, the utility model discloses an irritability is littleer, has avoided the patient to have the urine meaning for a long time under the condition that no urine can be arranged.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, the double-balloon double-cavity latex urinary catheter of the present invention comprises a urinary catheter body, wherein a urinary catheter cavity 6 and a balloon cavity 7 which are arranged in parallel are arranged in the urinary catheter body; the extending end of the catheter body is provided with a urethral catheterization opening 2, the extending end is provided with a urethral catheterization cavity opening 5, the urethral catheterization opening 2 and the urethral catheterization cavity opening 5 are communicated with a urethral catheterization cavity 6, and urine enters the urethral cavity 6 from the urethral catheterization opening 2 and is discharged from the urethral cavity opening 5; the catheter body is also provided with a buffering air bag 1 and a fixing air bag 3 which are made of elastic materials and are both communicated with an air bag cavity 7, the extending end of the catheter body is provided with an air bag cavity opening 4 communicated with the air bag cavity 7, air or liquid is injected into the two air bags through the air bag cavity opening 4 to cause the two air bags to expand, wherein the fixing air bag 3 is arranged in the middle of the extending part of the catheter body, the extending end of the catheter body is clamped and fixed in the bladder after inflation and expansion, the buffering air bag 1 is arranged on the end surface of the extending end of the catheter body, the volume of the extending end of the catheter body can be increased after inflation and expansion, the buffering air bag is easy to deform when contacting with the inner wall of the bladder, so that the contact area between the catheter body and the bladder is increased, the two are in surface-surface contact, compared with the point end of the traditional catheter and the bladder in point-, avoiding the patient from having a long time urine under the condition that no urine can be discharged.
