For example, the bag 121 can be sleeved at the lower end of the shell 120 by using the material characteristics of the bag 121. Preferably, in order to enhance the connection stability of the bag 121 and the shell 120, a groove or a convex edge can be arranged on the shell 120 along the circumferential extension direction at the position where the shell 120 is sleeved with the bag 121. A fastener for tightening the bag 121 is correspondingly wound in the groove. The fastener can be a clamp or a strap.

[0054] The bottom of the second shell 122 or the bag 121 has an urine outlet for sequentially communicating with the catheter 130 and the urine storage bag 140.

[0055] It is conceivable that the shell 120 can also be provided with a groove along the circumferential extension direction at the position where the shell 120 is sleeved with the sleeve 110. A fastener for tightening the sleeve 110 is correspondingly wound in the groove. The fastener can be a clamp or a strap, which is not limited in particular.

[0056] Alternatively, the shell 120 can also be provided with a convex edge along the circumferential extension direction at the position where the shell 120 is sleeved with the sleeve 110 and the bag 121, respectively. The sleeve 110 and the bag 121 are wrapped on the convex edge by using the elastic characteristics of the sleeve 110 and the bag 121, so as to achieve more stable connection.

[0057] Based on the above-described scheme, when the anti-reflux mechanism is used, the top end opening and / or the bottom end opening of the shell 120 is communicated with the sleeve 110 at the corresponding end, and the penis of a male passes through the sleeve 110 (one or two sleeves). Since the sleeve 110 is soft and has elasticity, the first opening 111 can be self-adaptively matched and tightly attached to the penis, so as to form an opening seal and prevent urine from flowing upward in reverse. When the size of the first opening 111 is relatively not matched and affects the use, the first opening 111 can be transversely cut at a proper position close to the second opening 112 from the current first opening 111. Since the sleeve body 113 of the sleeve 110 is in a structure of being small at the top and large at the bottom, the diameter of the first opening 111 after being cut can be increased, so that the size is re-adapted and normal use can be achieved.
