Abstract
Inflating and deflating device adapted to be used by a human hand. It comprises a housing and a syringe carried by the housing. The syringe comprises a syringe body having an outlet through which liquid can pass and a piston slidably mounted in the syringe body and forming a sealing engagement with the body. A piston rod is secured to the piston and extends out of the body. A tubular member is provided. A connector means connects the tubular member to the outlet of the syringe body. A handle is carried by the housing and is secured to the syringe for causing relative movement between the piston and the syringe body. The handle means includes first and second portions movable with respect to each other. The first portion is secured to one of said piston rod or said syringe body and the other said portions are secured to one of the other of said piston rod and said syringe body. The first portion is of a size so as to be adapted to being engaged by all of the fingers of the hand and the second portion is adapted to be engaged by the palm of the hand during the time that the fingers of the hand are engaging the first portion whereby a force to cause relative movement between the piston and the syringe body can be created by that hand.
