Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b):

referring to the attached drawings 1-6, the catheter comprises a catheter holder 1 and a catheter 3 integrally connected with the catheter holder 1, wherein the catheter 3 is made of natural latex, and a through cavity 11 is formed in the catheter holder 1 and the catheter 3 and can discharge urine of a patient.

The end of pipe seat 1 can be dismantled and be connected with guide wire seat 2, the seal wire 14 is connected with guide wire seat 2 through connecting platform 15, be provided with the external screw thread on the connecting platform 15, the end of pipe seat 1 is provided with the internal thread with connecting the 15 cooperations of platform. The guide wire seat 2 is connected with a guide wire 14, and the guide wire 14 is arranged in the cavity 11. The guide wire 14 may increase the strength of the catheter 3 so that the catheter 3 does not easily bend or become obstructed when entering the urethra of a patient.

The right end of pipe 3 is provided with screens gasbag 7, the outer wall of pipe seat 1 is provided with first trachea 6, seted up "L" type first air flue 12 on pipe seat 1 and the pipe 3, the first air flue 12 one end of "L" type link up with first trachea 6, the other end links up with screens gasbag 7. When the catheter 3 enters the bladder of a patient, the clamping air bag 7 is expanded through the first air pipe 6 and clamped in the bladder of the patient, so that the catheter 3 is prevented from falling out of the bladder.

The side wall of the catheter 3 is further provided with a flushing port 8, the outer wall of the catheter holder 1 is provided with a flushing pipe 4, the catheter holder 1 and the catheter 3 are provided with an L-shaped flushing channel 13, one end of the L-shaped first air channel 13 is communicated with the flushing pipe 4, and the other end of the L-shaped first air channel 13 is communicated with the flushing port 8. Catheter 3 is when patient's urethra, and lubricated liquid injection cylinder is connected to washing pipe 4, washes 8 lubricated liquid that ooze of mouth, helps catheter 3 more smooth and easy entering patient's urethra. After the catheter 3 has drained urine into the patient's bladder, the patient's bladder is cleaned by injecting a flushing fluid through the flushing tube 4. And can also inject anti-inflammatory drugs into the bladder of the patient to prevent and treat urinary system infection.

The side wall of the catheter 3 is further provided with a cylindrical air bag 16, the cylindrical air bag 16 is arranged on the right side of the clamping air bag 7, the cylindrical air bag 16 has the characteristic of low stretching capacity, the outer wall of the catheter seat 1 is provided with a second air pipe 5, the catheter seat 1 and the catheter 3 are provided with an L-shaped second air passage 17, one end of the L-shaped first air passage 13 is communicated with the second air pipe 5, and the other end of the L-shaped first air passage is communicated with the cylindrical air bag 16. Card in patient's bladder after screens gasbag 7 inflation, cylinder gasbag 16 is located patient's urethra this moment, and second trachea 5 switches on outside air supply and aerifys, makes card in patient's urethra after 16 expansions of cylinder gasbag, avoids patient's urethra to leak urine.

An arc-shaped catheter head 9 is integrally arranged at the tail end of the catheter 3, and the inner diameter of the catheter head 9 is smaller than that of the catheter 3. The tail end of the guide wire 14 is a sphere 10, and the diameter of the sphere 10 is larger than the inner diameter of the catheter head 9. After the catheter holder 1 and the yarn guide holder 2 are screwed, the sphere 10 is located outside the catheter head 9, on one hand, the arc-shaped catheter head 9 helps the catheter 3 to enter the urethra, on the other hand, the sphere 10 can prevent the edge of the catheter head 9 from scratching the urethra, and meanwhile, the solid sphere 10 is favorable for the catheter 3 to enter. When the catheter 3 enters the bladder for urination, the guide wire holder 2 is screwed out, and because the catheter 3 is made of flexible rubber, the spherical body 10 can stretch the catheter head 9 to enter the cavity of the catheter 3 and then be pulled out.

And valves are arranged on the first air pipe 6, the flushing pipe 4 and the second air pipe 5, and when the first air pipe 6, the flushing pipe 4 or the second air pipe 5 is not required to be used, the corresponding valves are closed.

The principle and the using process of the utility model are as follows:

when the guiding catheter is used, the free end of the guiding wire 14 is inserted into the cavity 11 of the guiding catheter base 1 and the guiding catheter 3, the spherical body 10 is arranged to protrude out of the tail end of the guiding catheter 3, and the guiding catheter base 1 and the guiding catheter base 2 are screwed tightly.

Then the catheter 3 is inserted into the urethra of the patient, the flushing pipe 4 is connected with the lubricating liquid cylinder, and the lubricating liquid is injected to enable the catheter 3 to penetrate into the urethra of the patient more smoothly.

After the catheter head 9 of the catheter 3 enters a proper position of the bladder of a patient, the first air tube 6 is connected with the inflating device, and the clamping air bag 7 is inflated and filled with air and clamped in the bladder of the patient to finish fixing.

The guide wire holder 2 is unscrewed and the guide wire 14 is withdrawn from the cavity 11 of the catheter 3.

At the moment, the cylindrical air bag 16 is positioned in the urethra of the patient, the second air pipe 5 is communicated with an external air source and is inflated, so that the cylindrical air bag 16 is clamped in the urethra of the patient after being expanded,

after the urine is discharged, the washing tube 4 is connected with the washing barrel to spray washing liquid to wash the bladder of the patient, so that residual inflamed tissues are discharged completely. Then, the anti-inflammatory medicine is sprayed according to the requirement, so that the inflammation of the pathological part of the patient is reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
