Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.
Example 1
The utility model provides a head end embedding draws urine pipe, includes body 1 and sacculus 2, body 1 head end tip is equipped with notch 11, notch 11 with draw urine passageway 12 intercommunication. It can be understood that the recess 11 extends from the end of the catheter body 1 inserted into the bladder to the other end of the catheter body 1, and that the recess 11 together with the urine guide channel 12 serves as a urination channel of the catheter.
The sacculus 2 is fixed at the 11 inside walls in notch, just sacculus 2 is provided with two, and two sacculus 2 are in drawing urine passageway 12 symmetry setting. Specifically, a passage for filling gas or liquid (generally normal saline) into the balloon 2 is arranged in the urine drainage tube, so that the balloon 2 is inflated by filling gas or liquid into the balloon 2, and the head end of the tube body of the urine drainage tube is left in the bladder of the patient. The liquid in the bladder of the patient flows into the urine guiding channel 12 from the gap between the two balloons 2 through the notch 11, so that the drainage of the liquid in the bladder is realized.
Preferably, the head end of the tube body 1 is bent to facilitate the insertion of the head of the urine drainage tube into the bladder of the patient; the urethral catheterization tube can be used for patients with urethral stricture and prostatic hyperplasia, and the universality of the urethral catheterization tube is ensured. And in order to ensure the comfort of inserting the urine guiding tube, the outer side of the head end of the tube body 1 is arc-shaped, namely, the edge of the head end of the tube body 1 is rounded. Preferably, the head end of the tube body 1 is semi-spherical, so that the comfort of the patient using the urine drainage tube is further ensured.
Example 2
Based on embodiment 1, the urine drainage device further comprises a support body 3, wherein the support body 3 is located between the two balloons 2, one end of the support body 3 is inserted into the urine drainage channel 12, the other end of the support body 3 is located in the notch 11, and the middle of the support body 3 is provided with a urine channel 31, so that liquid in the bladder of the patient can flow into the urine drainage channel 12. The support body 3 is arranged between the two saccules 2, so that the situation that the orifice of the urine leading channel 12 is blocked after the two saccules 2 are expanded, and the urine can not be discharged smoothly is prevented.
Preferably, the end of the support body 3 in the recess 11 is larger than the end of the support body 3 in the urine guiding channel 12, so as to increase the gap between the two balloons 2 after inflation, and further prevent the urine guiding channel from being blocked after the two balloons are inflated. In this embodiment, the side wall of the support body 3 is an inward concave arc shape, so that the side wall of the balloon 2 is completely attached to the side wall of the support body 3.
