Abstract
The present invention is a kit designed with a novel sized catheter valve capable of directing fluid easily through two separate paths or restricting fluid passage completely. The novel catheter valve is easy for an operator to use due to the relatively large valve control. The novel valve catheter also has a color code as an added safety measure.
Claims
1. A medical kit for visualization of human anatomy comprising: a standard 16 French diameter Foley catheter connected to a drainage bag with the connection at a proximal portion of the Foley catheter and wherein a three-way adapter stopcock is connected at a proximal portion of the Foley catheter and a proximal portion of a standard cystoscopy tubing wherein the cystoscopy tubing is sterile; and the kit does not include the distention medium, as a standard 1000 cc sterile water or osmotically balanced fluid for human use in a bag are readily available.
2.

DETAILED DESCRIPTION
[0042] FIG. 1 is an overview of the kit with a Foley Catheter 1 with standard two channel 16fr lumen; a drainage bag 2; a three or four-way adapter 3 with stopcock for three position (drain, fill, occlude); and, standard cystoscopy tubing 4. This is the most basic setup. Foley catheters are very well known in the medical and surgical fields.
[0043] The inventive aspect of the present invention is two-fold. First the F.A.S.T. catheter valve 3 and second the arrangement of the other commercially available device portions with the F.A.S.T. catheter valve 3 in a single kit 10. The kit 10 can be sterile and arranged for quick assembly in the operating room in or out of the sterile field. The F.A.S.T. catheter valve 3 has a urine outflow portion 8 that is adapted for standard Foley drainage bag 2. The urine outflow portion 8 can be characterized as having a female shaped adapter for secure fluid sealed attachment to a urine collection bag or drainage bag 2. The F.A.S.T. catheter valve 3 also has a cysto attachment portion 9 that is adapted for standard cysto tubing 4 for irrigation of the bladder. The cysto attachment portion 9 can be characterized as having a female shaped adapter for secure fluid sealed attachment to cysto tubing for irrigating a bladder (not shown).
[0044] FIG. 1 shows the F.A.S.T. catheter valve 3 also has a Foley attachment portion 11 that is adapted for attachment to a standard Foley catheter 1. The Foley attachment portion 11 can be characterized as having a male shaped adapter for secure fluid sealed attachment to the Foley catheter tip 7 to be disposed in the bladder.
[0045] The F.A.S.T. catheter 3 valve also has a valve control 12 that can be placed in one of three positions, fill, stop, or drain by an operator applying pressure to the valve control 12 typically by pinching between a finger and thumb and rotating the valve control 12 relative to the urine outflow portion 8 and cysto attachment portion 9. When the valve control 12 is aligned over the urine outflow portion 8, urine will be drained from the bladder to the drainage bag 2.
[0046] When the valve control 12 is aligned over the cysto attachment portion 9, fluid will flow to the bladder via the cysto tubing 4, through the Foley catheter 1 and finally exit into the bladder via Foley catheter tip 7.
[0047] When the valve control 12 is aligned with the Foley attachment portion 11, no fluid will pass through the F.A.S.T. catheter 3.
[0048] FIG. 2 Shows the cross-section of a two way urinary catheter lumen for infusion lumen 5 for delibery of fluid through Foley catheter tip 7 and eventual fluid removal through drain lumen 6.
[0049] FIG. 3 shows an independent and unique aspect of the present invention, a F.A.S.T. three position catheter valve comprising a urine outflow portion 8, a cysto attachment portion 9, a Foley attachment portion 11, and a valve control 12.
[0050] FIG. 4 shows a close up view of the F.A.S.T. three position catheter valve 3. In a preferred embodiment the urine outflow portion 8 would be yellow to indicate that urine was the intended outflow. The cysto attachment portion 9 would be colored blue to indicate that water or non-urine fluid would flow. Additionally, in the preferred embodiment a portion between urine outflow portion 8 and the cysto attachment portion 9 would be colored red such that when the control valve 12 was aligned with the red indication portion it would be indicate to the oipreator that no fluid should flow through the catheter valve 3.
[0051] FIGS. 5A-5B shows the F.A.S.T. three position catheter valve in the drain position. Specifically, FIGS. 5A-5B show the F.A.S.T. three position catheter valve 3 with the valve control 12 in alignment with urine outflow portion 8 while the Foley attachment portion 11 creates a through path 30 from the bladder. FIG. 5B shows a cutaway view through the shows the F.A.S.T. catheter valve 3. When the valve control 12 is in fluid communication between urine outflow portion 8 and Foley attachment portion 11, the cysto attachment portion 9 is sealed off and no fluid flows in or out through cysto attachment portion 9.
[0052] FIGS. 6A-6B shows the F.A.S.T. three position catheter valve in the fill position. Specifically, FIGS. 6A-6B show the F.A.S.T. three position catheter valve 3 with the valve control 12 in alignment with cysto attachment portion 9 while the Foley attachment portion 11 creates a through path 30 to the bladder. FIG. 6B shows a cutaway view through the shows the F.A.S.T. catheter valve 3, When the valve control 12 is in fluid communication between cysto attachment portion 9 and Foley attachment portion 11, the urine outflow portion 8 is sealed off and no fluid flows in or out through cysto attachment portion 9. The fluid only can only be directed into a patient bladder out the Foley catheter tip 7.
[0053] FIGS. 7A-73 shows the F.A.S.T. three position catheter valve in the clamped or stop position. Specifically, FIGS. 7A-7B show the F.A.S.T. three position catheter valve 3 with the valve control 12 in alignment with neither urine outflow portion 8 nor cysto attachment portion 9 so that there is no through path 30 between the patient bladder via Foley attachment portion 11 to move fluid in or out of the patient with the catheter valve 3. FIG. 7B shows a cutaway view through the shows the F.A.S.T. catheter valve 3. Typically, a patient would have their bladder filled and viewed by the surgeons, nurses, and associated clinicians. The bladder would be filled or drained during surgery to facilitate the visualization of the bladder relative to other tissue.
