BARIUM DEVICE This invention relates to machines for the examination of patients and more particularly to a barium device.
It is therefore the principal object of this invention to provide a barium device which provides for a control system of barium application, in combination with air contrast, if desired to be employed in the examination of patients.
Another object of this invention is to provide a barium of the type described, which employs lever means, piston means, hose means, valve means, and air control means so as to assure that barium enters the colon thereby renderring the patient ready for X-rays.
A further object of this invention is to provide a barium device of the type described, which will be superior to those of the prior art, in that, the present invention provides a control system of both the combination of barium and air.
Other objects of the invention are to provide a barium device which is simple in design, inexpensive to manufacture, rugged in construction easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the following specification and the accompanying drawings, wherein:
FIG. 1 is a perspective view of the present invention.
FIG. 2 is a perspective view of the lever and wheel combination of the device which controls the operation of the two pistons shown in FIGS. 3 and 4 of the drawings.
FIG. 3 is a plan view of the piston contained unit of the device, shown in closed position.
FIG. 4 is similar to FIG. 3, but shows the unit in open position.
FIG. 5 is a perspective view of another piston contained unit of the device.
FIG. 6 is an exploded perspective view of the unit of the device which has air valve means and washer means for controling the barium and air flow.
According to this invention, a barium device 10 is shown to consist of a base 11 of which extending lever 12 controls the function of the device 10. Barium is kept in a reservoir 12a mounted on an IB stand (not shown) above device 10, the barium flowing by gravitational means downward. When device 10 is put into use, lever 12 is moved from the locked position L1 as shown on face 13 and is set to the letter B upon face 13. Barium is then allowed to flow through rubber surgical tube, identified as 14, through 15 and into the section labeled B of unit 16. The fluid continues to flow into surgical tube 17, into the patient, in order to assure that barium enters the colon, an air contrast system is employed. This is accomplished as follows:
To further describe device 10 in detail, FIGS. 3 and 4 show the unit 15 (open and closed) respectively and FIG. 2 shows the lever 12 uncovered. As is shown in FIG. 2, lever 12 is secured fixedly to an isometric wheel 24 mounted on the colonic device 10, base 11, by means of a column support (not shown). This lever 12 by circular motion, controls the operation of two pistons 25 and 26 as shown in FIGS. 3 and 4 of the drawings. The pistons 25 and 26 in effect, apply direct pressure on the surgical tubing within which will contain air or barium. The function of unit 21 is such, that when lever 12 is at position B, on face 13, the piston 27 of this unit 21, compresses against the surgical tubing enclosed in the system so that the barium flows to the patient. When the lever 12 is moved to positions L1 and L2 and A, the unit 21 still remains closed. When lever 12 is moved to the position D (drain) and W (wash), piston 27 is released and allows fluid to flow out of device 10 and into the collection receptacle.
Referring to FIG. 6 of the drawing, the letter B indentifies the upper part of the unit where barium is allowed to flow when desired. The lower portion represents the air contrast aspect A. When the squeeze bulb 18 is employed to pump air into the patient, a rubber washer 28 and a nylon ball 29 with spring 30 means, prevents air from returning through the system. Washer 28 will prevent barium from backing into the air system.
It shall be noted that the wheel disc 24 secured fixedly to lever 12 has an inner disc attached that is flat in certain areas and recessed in others. When the control lever 12 is moved from one position to the next, the disc on the inner surface, in turn, controls the side movement of the pistons 25 and 26. The larger outer wheel 24 controls the movement of the piston 27 as shown in FIG. 5 of the drawings.
It shall be further be noted that the ends of the pistons 25 and 26 of FIGS. 3 and 4, are provided with a wheel bearing 25a and 26a respectively, the said bearings serving to reduce friction and will rotate when the control lever 12 is moved from one position to the other. The piston 27 of unit 21, includes a surface cap 21a.
What I claim is:
l. A barium device, comprising base means for mounting air and barium control means, lever and wheel means pivotably carried within said device for controlling the barium fluid and air, said control lever is fixedly to said wheel which is isometric, said wheel having face means of different levers for controlling the fluid and air means through said device, hose and reservoir means secured to said base providing for gravitational feed means of said barium fluid, an air squeeze bulb secured to said device providing for air entering said wheel of said lever being secured to post means secured fixedly to said base of said device and locking lever means of said device is pivotably secured to the unit of said device having a pair of pistons, each of said pistons including a pivotable wheel bearing for reducing friction during the operation of said device.
