Detailed Description

The above-described aspects are further described below in conjunction with specific embodiments. It is to be understood that these examples are illustrative of the utility model and are not intended to limit the scope of the utility model. The implementation conditions used in the examples may be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are generally those in routine experiments.

In a specific embodiment, a dredged catheter is provided, which comprises a catheter main body 1, wherein a liquid draining cavity 1.1 is communicated with the rear end of the catheter main body 1, and a liquid inlet is formed in the front end of the catheter main body 1. The catheter main body 1 is placed in a human body, the liquid inlet at the front end part of the catheter main body is positioned in the bladder, the liquid discharge cavity 1.1 is placed outside the human body, urine in the bladder can flow out from the liquid discharge cavity 1.1 through the drainage of the catheter main body 1, and the urine is discharged outside the human body.

The rear end of the catheter main body 1 is also communicated with a reset cavity 1.4, a dredging balloon 2.1 is movably arranged in the reset cavity 1.4, the dredging balloon 2.1 can be placed in the reset cavity 1.4, and when the dredging balloon 2.1 is placed in the reset cavity 1.4, the catheter main body 1 is communicated with the liquid drainage cavity 1.1, so that drainage is realized.

The mediation sacculus 2.1 is connected through seal wire 2.2, and seal wire 2.2 other end stretches out reset chamber 1.4 to seal wire 2.2 and reset chamber 1.4 sliding seal, when catheter main part 1 carries out the drainage, liquid can not overflow from reset chamber 1.4 and seal wire 2.2's gap, because reset chamber 1.4 is the same with catheter main part 1 material, is materials such as rubber, latex, silica gel, has certain elasticity, when seal wire 2.2 passed reset chamber 1.4, reset chamber 1.4 around seal wire 2.2 can begin to clip seal wire 2.2, realizes sealed effect.

And drag or promote seal wire 2.2, dredge sacculus 2.1 can remove in catheter main part 1 and reposition chamber 1.4, when catheter main part 1 is in drainage urine, because tiny blood clot in the bladder can be brought into catheter main part 1 by the urine, block up catheter main part 1, remove dredge sacculus 2.1 this moment, can promote the blood clot that blocks up in catheter main part 1, make the blood clot that blocks up together loosen or change the form, can discharge outside the body along with the liquid flow, dredge catheter main part 1.

As a preferable scheme of the catheter main body 1, a flushing cavity 1.3 is communicated with the rear end of the catheter main body 1, a one-way valve is arranged in the flushing cavity 1.3, and a flushing port is formed in the front end of the catheter main body 1. By injecting the flushing liquid into the catheter body 1 from the flushing lumen 1.3, the effect of dredging the catheter body 1 can also be achieved to a certain extent, and the formation of blood clots in the bladder can also be avoided by the flushing liquid entering the bladder, so that it is dissolved in the flushing liquid. And the one-way valve is arranged in the flushing cavity 1.3, so that the liquid drained from the catheter main body 1 cannot flow out of the flushing cavity 1.3.

As a preferable scheme of the catheter main body 1, a water injection cavity 1.2 is arranged at the rear end of the catheter main body 1, a balloon 1.5 is arranged on the side wall of the catheter main body 1, the balloon 1.5 is communicated with the water injection cavity 1.2, and the balloon 1.5 can be inflated by injecting water/air into the water injection cavity 1.2. When the catheter main body 1 is placed in a human body, the balloon 1.5 is also placed in the bladder, air or liquid is injected into the balloon 1.5 through the water injection cavity 1.2, the balloon 1.5 can be inflated, the balloon 1.5 is clamped at the position of a triangular area in the bladder, the catheter main body 1 is fixed, and the catheter main body 1 is prevented from slipping from the urethra.

There are two specific embodiments of the water injection lumen 1.2 and balloon 1.5 described above:

in a first embodiment, the balloon 1.5 is provided with one, which is arranged near the front end of the catheter body 1. The catheter body 1 is secured by clamping the balloon 1.5 in the position of the intravesical triangle.

In a second embodiment, two balloons 1.5 are provided, wherein one balloon 1.5 is arranged at a position close to the front end part of the catheter main body 1, and the other balloon 1.5 is arranged away from the front end part of the catheter main body 1. When the catheter is used, the balloon 1.5 far away from the front end part of the catheter main body 1 is clamped at the position of the trigone in the bladder, and huge blood clots possibly exist in the bladder, so that the liquid inlet at the front end part of the catheter main body 1 can be always kept at the outer side of the blood clots after the balloon 1.5 close to the front end of the catheter main body 1 is inflated, and the huge blood clots are prevented from blocking the liquid inlet.

As a preferred scheme of the dredging balloon 2.1 and the guide wire 2.2, an air passage 2.21 is formed in the guide wire 2.2, the air passage 2.21 is communicated with the dredging balloon 2.1, and the dredging balloon 2.1 can be controlled to expand or contract through the air passage 2.21. Because the blood clot in the catheter main body 1 is pushed by the dredging balloon 2.1 alone and can not dredge the catheter main body 1, the dredging balloon 2.1 is arranged to be of an air sac structure, the expansion or contraction of the dredging balloon can be controlled by the air passage 2.21 in the guide wire 2.2, when the dredging balloon 2.1 is contracted, the dredging balloon 2.1 is pushed to penetrate through the blood clot clamped in the catheter main body 1 by pushing the guide wire 2.2, then the dredging balloon 2.1 is inflated by the air passage 2.21 to enable the expansion of the dredging balloon to be equal to the inner diameter of the catheter main body 1, the dredging balloon 2.1 is pulled backwards to drive the blood clot to move towards the rear end of the catheter main body 1, and because the inner diameter of the liquid draining cavity 1.1 is larger than the inner diameter of the catheter main body 1 in reality, the blood clot can be drained from the liquid draining cavity 1.1, and the dredging of the catheter main body 1 is realized. Moreover, place the mediation sacculus 2.1 after the inflation in catheter main part 1, carry out the shutoff to it, make catheter main part 1 unable drainage, when making things convenient for the doctor to carry out clinical operation to the patient, do not have the urine outflow, influence doctor's operation.

In order to further realize the penetration of the dredging balloon 2.1, it is preferable that a protruding thorn part 2.11 is arranged at the end part of the dredging balloon 2.1, and the protruding thorn part 2.11 is a conical structure with a tip end rushing to the outer side of the dredging balloon 2.1. The stab part 2.11 is arranged at the front end part of the dredging saccule 2.1 in the moving direction, the guide wire 2.2 is pushed forward, and the stab part 2.11 at the front end of the dredging saccule 2.1 can easily stab blood clots blocked in the catheter main body 1.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
