摘要： A seal for the accessory port of a medical instrument comprises a first region having an aperture formed in elastomeric material. The aperture permits an accessory of slightly greater diameter to be sealably introduced through the accessory port of the instrument. The seal includes a second region of elastomeric material distal to the first region, which includes a hatch with a closeable passageway. The hatch sealably engages the accessory and also seals the accessory port when no accessory is in place. The first region and/or the second can be stretched and distorted as an accessory passes therethrough. Therefore, it is preferable to dispose a relief cavity between the aperture and the hatch. The relief cavity separates the two regions so that the aperture and hatch can each independently maintain an effective seal around an accessory. The relief cavity also provides a break between the aperture and hatch that minimizes drag on the accessory. The seal may include a compression element around the outer surface. Preferably, the compression element is a ring that provides predetermined coaxial compression on the passageway in the hatch through which an accessory is extended.

摘要翻译： 用于医疗器械的附件端口的密封件包括具有形成为弹性体材料的孔的第一区域。 孔径允许通过仪器的附件孔密封地引入稍大直径的附件。 密封件包括远离第一区域的弹性体材料的第二区域，其包括具有可闭合通道的舱口。 舱盖密封地接合附件，并且当没有附件就位时也密封附件端口。 随着附件通过，第一区域和/或第二区域可以被拉伸和变形。 因此，优选在孔和舱口之间设置浮雕腔。 释放腔分离两个区域，使得孔和舱口可以各自独立地保持围绕附件的有效密封。 减压腔还提供孔和舱口之间的间隙，使附件上的阻力最小化。 密封件可以包括围绕外表面的压缩元件。 优选地，压缩元件是环形件，其在舱口中的通道上提供预定的同轴压缩，通过该压缩元件延伸附件。
