Abstract:
1. A pretreatment instrument comprising a swab and a mixing container for saliva and a treatment liquid, the swab comprising a stick at a front end of which is fixed a soft synthetic resin-made sponge capable of absorbing a predetermined amount or more of saliva, the mixing container being made of a transparent or translucent soft synthetic resin and comprising a bag-like portion formed integrally with and continuously to a constricted portion at the end of a tapering introduction portion having an opening thoroughly larger than the soft synthetic resin-made sponge of the swab, into which the soft synthetic resin-made sponge can be inserted, the constricted portion and the bag-like portion in the mixing container have elasticity such that the soft synthetic resin-made sponge can be squashed by a finger pressure in a state that the soft synthetic resin-made sponge is inserted within the constricted portion and the bag-like portion; and the constricted portion has a width such that a pressure can be applied by fingers and has a shape such that when the soft synthetic resin-made sponge of the swab is taken out in a squashed state by the finger pressure, a minimum amount necessary for the pretreatment of saliva or more amount of the saliva can be squeezed out.
