Abstract
A pneumatically operated chiropractic thruster or manipulator that has a gun shaped body including an upper barrel and lower handle wherein the thrust element is free to move inwardly when depressed against a body to accommodate automatically different stroke lengths, and the force delivered is adjustable by changing air pressure at the thruster by a rotatable needle valve knob control having a predetermined number of indicated settings. Also, the thruster can be operated with a single or a multiple thrust mode upon a single depression of a valve activator trigger.
Claims7
A pneumatic chiropractic thruster adapted to be connected to a source of compressed air supply comprising in combination:
- a body portion including a thruster head element;
- said head element being freely moveable against one end of a biasing means within the body portion;
- a piston reciprocally moveable within the body portion and acting against the other end of said biasing means;
- trigger operated valve means carried by the body portion and located between inlet and outlet ports for delivery of air from the source to the outlet port upon operation of the valve means;
- said outlet port being connected to a chamber behind said piston to receive the air supply and drive the piston forwardly towards and into contact with the thrust element;
- and
- adjustable control valve means interposed between the outlet port and chamber for selectively changing the amount of air under pressure supplied to drive the piston forward.
