Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a portable super-slip intermittent urinary catheter. Background Art

[0002] For patients with neurogenic bladder due to spinal cord injury, their kidney, bladder and urethral functions usually remain normal. However, long-term reliance on indwelling catheterization will inevitably lead to bladder function deterioration. Therefore, the medical community generally recommends the use of intermittent catheterization to maintain the patient's bladder function.

[0003] Before using the traditional intermittent catheter, lubricant (such as liquid paraffin or silicone oil) needs to be applied manually on its surface, and then inserted into the urethra for catheterization. However, manual application is not only cumbersome, but also the application quality cannot be guaranteed. Moreover, such lubricant applied later is easy to fall off into the urethra and bladder during the insertion process, and the lubrication effect is limited. In order to overcome the above defects, the improved super-slip intermittent catheter came into being. The surface of this catheter is pre-coated with a super-slip coating. Before use, it is soaked in water until the coating is fully moistened and swollen, and then it can be inserted into the urethra and bladder for catheterization. The operation is simple and the lubrication effect is good. However, the use of this catheter requires additional water source and container before operation, and the patient is required to wait patiently for the coating to absorb water and activate, which limits the flexibility of use. In addition, the above two catheters are not only of considerable length, but also usually packaged in a slender state, which is not convenient for carrying outside; after use, the catheter is exposed and lacks a container, which is not conducive to the disposal after catheterization. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a portable super-slip intermittent urinary catheter which has good lubrication effect, is flexible and light to use, is easy to dispose of after catheterization, and is suitable for carrying outside in view of the deficiencies in the prior art.
