Japanese Patent JPS618313
Kind Code:
B2
Abstract:
A valve assembly comprises a resilient housing of plastic material and a valve element in the form of a unitary plastic body located within the housing. The body is closed at one end by a dish-shape portion having a circumferential lip which forms a seal with the housing. The body has a tongue formed in its wall, one end of the tongue being provided with an inwardly directed tooth. By inserting a tube or rod within the valve element to engage the tooth, the tongue can be displaced outwardly and the overlying part of the housing can thereby be distorted away from the lip to permit fluid flow through the housing. The valve assembly may be used to seal one end of the inflation line of a cuffed medico-surgical tube.
