Best Mode for Carrying out the Invention
Referring now in detail to the drawing for the purpose of i I lustrating preferred embodiments of the present invention. The device as seen on Fig 1 and Fig 2 are elevational perspective views of the flow controller and Fig 3 and Fig 4 are sectional views of under the embodiments of the present invention.
The Prior art relates to a feature comprising a inclined grooves(2) along the inside frame and a movable roller(4) joined into the groove(2) such that the roller(4) performs a sliding operation. The pressuring on resilient supply hose(7) using a rol I er (4) adjust the flow of solution while in a injection. This invention is directed to improve on the prior art providing an stopping device and indicat ing means.
A scale(6) for the indication of flow rate or amount is denoted on the outside of controller's framed) along the grooves(2). A division of the scale set by the empirical data provide a valuable guide for the duration of injection. A division of the scale can be denoted as a relative time unit (0.5 hour, 1hour , 1.5 hour...) or number unit (1, 2, 3,...) corresponding to the flow rate through the resi I ient supply tube.
The injection of Ringer's solution is finished according to the indicating means by setting the axis(5) of rol Ier (4) to the hole(3) position. The stopper's holes(3) apertured along the both side of the frame(1) is joined with the axis(5) of rol Ier (4) so that the stopping can be achieved in a appropriate position. The amount of solution can be controlled at the stopper's position.
For example, the holes are apertured with a uniform division of 30 min. as seen on Fig 2, the positioning of the axis(5) of rol I er (4) into the apertured holes(3) cause that the fluid through the supply tube can be controlled to a patient's body according to the marked indicat ion(6) as seen on Fig 1.
More specifically, the protruding stoppers(la) configured symmetrically along the top and bottom of the guide rail (2a) provide a stopping position for the axis(5) of the rol I er (4) . The supply hose(7) inserted between the inclined bottom of the controller's framed) and the roller (4) is oppressed or depressed according to the linear position of the axis(5) along the guide rail (2a) whereby the solution through the resilient tube(7) can be controlled. Fig 5 represents the second illustration of the invention. The casings(δ) are combined together in the upper and lower direction.
Inside of the casings(δ), a adjustable s I i der (11) is installed along the openingdO) inner part of the upper casing so that the push pad(9) can oppress or depress the resilient supply hose(7).
Fig 6 shows the third illustration of the invention. A rotating type of controlling rol Ier ( 12) having tapering thickness is installed in the casings(8). The axis of roller is fixed the upper and lower part of the casings(δ) so that the roller can rotate in clockwise or anticlockwise direction. Using a push ball (8a) located on the bottom of the rol ler ( 12) , the supply tube(7) is oppressed or depressed by the rotating rol ler ( 12) depending on the direction of rotation whereby the push ball (8a) on the tube(7) control the flow of solution in the resilient supply tube(7). Fig 7 shows the fourth illustration of the invention. The upper and lower casing(8) are combined with each other using bevel screwed hollow casings(δb). The supply tube(7) passed through the center of the casings(8) is oppressed or depressed by the inside wall of the inner screwed casing(δb). The flow of solution through the resilient supply tube(7) is controlled according to the indication marked around the surface of casing(β).
As seen on the illustrations, the applications of embodiment of the indicating means and stopping device for the controller can be ut i I ized to var ious ways.
