Description
Technical Field
The utility model relates to the medical field, in particular to an anti-seepage catheter.
Background
A urinary catheter is a conduit that is inserted into the bladder from the urethra in order to drain urine.
When the catheter is used, the urethra is blocked by the saccule, so that urine is promoted to flow out of the catheter, and finally the urine is collected by the drainage bag. During this process, urine exudes due to the balloon volume either being imprecise due to occlusion or shrinking due to the passage of time. After such situations, not only are the clothes bedsheets soiled, but also the statistics of the urine volume to the patient are difficult to implement, and most of all, the catheter blockage is difficult to find and the statistics of the physical condition of the patient are difficult to implement.
After 2-3 times of replacement (a part of patients can be replaced twice a week, and the drainage bag can be replaced together with the drainage tube under part of conditions) of a patient, once the drainage tube is replaced too much, the catheter can not be sealed with the drainage bag due to the loss of elasticity, so that urine permeation occurs.
At present, the anti-seepage catheter generally adopted for the former is generally assisted by filling objects such as absorbent cotton, but long-term use leads to liquid accumulation and easy bacterial growth. While the latter problem is not currently well-resolved.

Detailed Description
The present invention will be further described with reference to the following examples in order to better understand the technical solutions of the present invention and to make the above features, objects and advantages of the present invention more clearly understood. The examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 to 4, the present utility model includes: a catheter (1), drainage lines (11) are arranged on the outer side of the catheter body at the rear of the air bag of the catheter (1), a plurality of the drainage lines (11) are distributed on the outer side wall of the catheter (1) at equal angles,
The drainage structure is arranged at one end of the drainage lines (11) and comprises absorbent cotton (2) surrounding the outer side of the catheter (1), and binding rubber (3) wrapping the outer side of the absorbent cotton (2), wherein the binding rubber (3) is communicated with the inner cavity of the catheter (1) at the liquid outlet of the catheter (1) through an external pipe;
The catheter is characterized in that a sealing ring (4) is arranged at the joint of the catheter (1) and the external drainage tube, the sealing ring (4) is provided with an opening, and sealing cotton (5) is arranged inside the sealing ring.
