    • A urinal or incontinence apparatus is disclosed which employs elastic tubular membranes that are opened and closed by collars mounted for coaxial relative rotation. In one embodiment a pair of the membranes are mounted so that when the collars are turned in one rotational sense, one of the membranes is twisted to constrict towards a closed position forming a seal about the penis while the other membrane is twisted so as to expand toward an open position. At the neutral position, elastic counterforces created in the membranes are in balance so that the membranes are held in their partially open positions for insertion or removal. When the collar is moved beyond the neutral position the elastic force in one membrane overbalances that of the other membrane, which is thereby maintained in its sealed position. When removed, the membranes operate by snap action so that one is maintained in its fully closed position preventing leakage from a urine collection bag. In another embodiment a single flexible membrane is attached at its ends to a pair of collars which are threadably mounted together. As the collars are screwed together, the membrane constricts until it reaches its closed position when rotation of the collars is stopped by the threads.
    • 公开了一种小便器或失禁设备,其使用弹性管状膜,其通过安装成用于同轴相对旋转的轴环打开和关闭。 在一个实施例中,安装一对膜,使得当套环以一个旋转方向转动时,其中一个膜被扭转成朝着封闭位置收缩,形成围绕阴茎的密封,而另一个膜被扭转以便膨胀 朝着敞开的位置 在中立位置,在膜中产生的弹性反作用平衡,使得膜保持在其部分打开的位置用于插入或移除。 当套环移动超过中性位置时,一个膜中的弹性力使另一个膜的弹性力过大,从而将其保持在其密封位置。 当移除时,膜通过快速动作进行操作,使得其保持在其完全关闭位置,从而防止尿液收集袋泄漏。 在另一个实施例中,单个柔性膜在其端部附接到一对轴环,该套环螺纹安装在一起。 当套环拧紧在一起时,膜片会收缩,直到套圈的旋转被螺纹停止时才到达其关闭位置。
