Abstract: A stoma seal is described for a controlled evacuation ostomy appliance. The stoma seal may have a liquid-responsive property, such as hydrophobic, hydrophilic or absorptive. The stoma seal may have a non-smooth surface, e.g., at a microstructure scale. The non-smooth surface may consist of tortuous channels, protruding seals, or a confronting apertured or porous layer. The liquid-responsive property and/or the non-smooth surface may facilitate separation of flatus from faecal matter and/or facilitate venting of flatus while obstructing stool.

Abstract: The end of the elongated tubular element of the appliance that is designed to be inserted into a body cavity is formed entirely of soft, compliant material. That end carries an inflatable balloon made of non-expandable material, formed in the fully inflated shape, to prevent overexpansion. The balloon is inflated to a predetermined low pressure level to prevent pressure necrosis in the adjacent tissue. A method and apparatus for introducing the soft end of the appliance into the body cavity are also provided. The introducer apparatus includes rigid core surrounded by a soft, compliant sleeve. The sleeve extends beyond the rigid core to form an invertable section. The soft end of the appliance is situated adjacent the apparatus, the balloon is wrapped around the apparatus, and the sleeve section is inverted over the appliance, compressing the balloon and forming a soft, rounded insertion tip. The unit is then introduced into the body cavity. After the appliance is separated from the apparatus, the apparatus is withdrawn.

Abstract translation: 设计成插入体腔的器具的细长管状元件的端部完全由柔软的柔顺材料形成。 该端部承载由不可膨胀材料制成的可膨胀气囊，其形成为完全膨胀的形状，以防止过度膨胀。 气囊膨胀至预定的低压水平以防止邻近组织中的压力坏死。 还提供了用于将器具的软端引入体腔的方法和装置。 导引器装置包括由软的柔性套筒包围的刚性芯。 套筒延伸超过刚性芯以形成可逆的部分。 器具的软端位于设备附近，气囊被包裹在设备周围，并且套筒部分在器具上翻转，压缩气囊并形成软的圆形插入尖端。 然后将该单元引入体腔。 在器具与设备分离后，设备被取出。
