Description
Technical field
The present invention relates to a kind of field of medical device, a kind of particularly multi-cavity ureter bracket.
Background technology
Existing more than the 40 years history of the Clinical practice of single-chamber ureter bracket (as shown in Figure 1), delays to ureteral obstruction
The effect of solution has clearly.It is one and obstruction property, ureteral peristalsis, support tubing property and shape that stand tube, which alleviates obstruction,
The closely related complicated hydrodynamics process of shape.The stand tube for passing through region of obstruction does not ensure that offer is sufficiently drawn
Stream.Long term drainage mortality is up to 16%~53%.The main reason for failure is probably by serious parcel, side opening around stand tube
Blocked in mucous membrane of ureter filling and tube chamber by slough and clot.
The content of the invention
In order to solve the problems, such as that existing single-chamber ureter bracket drainage effect is bad, the invention provides a kind of multi-cavity is defeated
Urinary catheter support, the multi-cavity ureter bracket can both increase intracavitary drainage, can be distorted again by reducing the external pressure of ureter
Support tube chamber external drainage is added with compressing, effectively prevents that support from seriously being wrapped up and the adhesion with tissue.Long term drainage
Mortality can be reduced within 5%.

The distance of heart line is identical with the distance of the center line to the second straight tube.
Straight length is also located at outside the first straight tube and the second straight tube containing two the 3rd separate straight tubes, the 3rd straight tube,
The outer wall of 3rd straight tube is connected with the outer wall of the outer wall of the first straight tube and the second straight tube, and two the 3rd straight tubes are on the first straight tube
Plane where the center line of center line and the second straight tube mirror image each other, the center line of two the 3rd straight tubes is into the first straight tube
The distance of heart line is identical with the distance of the center line to the second straight tube.
Straight length contains two the second separate straight tubes, and the center line of two second straight tubes is parallel to each other, two pieces the
Two straight tubes and the first straight tube are distributed in equilateral triangle, the outer wall connection of two second straight tubes.
Straight length is also located at outside the first straight tube and the second straight tube containing a 3rd independent straight tube, the 3rd straight tube, and the 3rd
The outer wall of straight tube is connected with the outer wall of the first straight tube and the outer wall of the second straight tube, and the center line of the 3rd straight tube is into the first straight tube
The distance of heart line is identical with the distance of the center line to the second straight tube.
Straight length contains three the second separate straight tubes, and the center line of three second straight tubes is parallel to each other, three pieces the
Two straight tubes and the first straight tube are in equilateral square.
Straight length is also located at outside the first straight tube and the second straight tube containing a 3rd independent straight tube, the 3rd straight tube, and the 3rd
The outer wall of straight tube is connected with the outer wall of the first straight tube and the outer wall of the second straight tube, and the center line of the 3rd straight tube is into the first straight tube
