Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The attached drawings are simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

The first embodiment is as follows: shown by fig. 1-3, the utility model discloses a double-cavity pipe, the double-cavity pipe includes evacuation cavity 1 and fills chamber 2, evacuation cavity 1's top intercommunication has drainage cone interface 3, the top intercommunication that fills chamber 2 has filled cone interface 4, fill the lower extreme fixedly connected with cone sacculus 5 in chamber 2, cone sacculus 5's pointed end up, cone sacculus 5's bottom fixedly connected with head 6, the side of head 6 is equipped with side opening 7, side opening 7 and evacuation cavity 1 intercommunication.

The outer layer of the double-cavity tube is a silica gel layer, the inner layer of the double-cavity tube is latex, and the surface layer of the latex hose is subjected to silicification treatment, so that the rubber hose is good in physiological compatibility, smooth and small in irritation to urethra, and pain of urethral intubation of a user is reduced. The inflation cavity can be filled with sterile water or air through the injector, so that the cone air bag 5 is inflated and expanded, the cone air bag has good balance and stretchability, the double-cavity tube is convenient to fix in the bladder, the double-cavity tube is prevented from slipping from the bladder, the drainage cavity interface 3 can be externally connected with a drainage bag, and the drainage bag is replaced every day after being used, so that the infection probability is reduced.

In order to better prevent urine leakage, the upper end of the cone balloon 5 is connected with a spherical balloon 8. When water is injected or inflated into the spherical air bag 8, 10ml of water is not needed to be injected, and the water is injected too much to stimulate the bladder, so that the bladder contracts and cramps to a certain extent, and the leakage of urine from the urethral orifice is easy to cause.

In order to better facilitate the inflation and deflation of the cone balloon 5, a non-return valve 9 is arranged in the inflation conical interface 4.

Example two: on the basis of the above embodiment, a flushing cavity 10 is arranged in the double-cavity tube, the upper end of the flushing cavity 10 is communicated with a flushing tapered interface 11, the top end of the head is provided with a flushing hole 12, and the flushing hole 12 is communicated with the flushing cavity 10.

Acute urinary tract infection, urine sediment production, calcium salt deposit, hemorrhage can lead to the ureter to block up, and the urine flows unsmoothly, and when the bladder capacity reached a certain amount, the urine appeared and spills over around the ureter, in order to prevent the jam of evacuation cavity 1, need wash in the bladder, drench the flush fluid from washing the taper connector 11 and squeezing into during the use.

Example three: on the basis of the above embodiment, in order to better prevent the double lumen tube from slipping off, the surfaces of the pyramidal balloon 5 and the spherical balloon 8 are provided with folds.

Example four: on the basis of above embodiment, in order to guarantee the unobstructed of escape cavity 1, be equipped with seal wire 13 in the escape cavity 1, seal wire 13 is worn out by excreting tapered interface 3, and fixedly connected with rotor 14, rotor 14 can rotate on excreting tapered interface 3.

The rotator 14 rotates to drive the guide wire to rotate in the drainage cavity 1, so that sediment and blood in the drainage cavity 1 can be stirred during flushing, and the drainage cavity 1 is prevented from being blocked due to the sediment of discharged liquid.

The utility model discloses novel structure, the design is ingenious, reasonable in design, the simple operation can effectively prevent to leak urine, and accurate measurement reduces medical personnel's working strength, and the antiskid is taken off and is made it more firm, prevents to excrete the jam that the drainage thing in the intracavity arouses, and can assist the intubate.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
