## Title
Universal valve for Foley type urinary catheter

## Abstract

A universal valve for the Foley type urinary catheter has structure which permits its use as a patient controlled drainage valve, as an interface from which to take sterile samples, and as a connection to a day or night collection bag all without removal of the universal valve from the Foley type urinary catheter. The universal valve may be open or closed by the use of a squeeze mechanism for patient control, or by movement of the threaded connection between the universal valve and a collection bag so that the universal valve is continuously open for drainage into the urine collection bag.

SUMMARY OF THE INVENTION
The present invention is a universal valve for the Foley type urinary catheter. The universal valve has structure which permits its use as a patient controlled drainage valve, as an interface from which to take sterile samples, and as a connection to a day or night collection bag all without removal of the valve from the Foley type urinary catheter.
The valve may be open or closed by the use of a squeeze mechanism for patient control, or by movement of a connection between the valve and a collection bag so that the valve is continuously open for drainage into the urine collection bag.
Use of the universal valve of this invention increases patient mobility as well as patient dignity because of the patient's ability to control flow. This control also makes the valve suited for use in establishing bladder control for patients whose mental and/or physical states are such that they are capable of such control.
Use of the universal valve also allows for patient self-control of urinary bladder retention.
The foregoing, as well as further objects and advantages of the invention will become apparent to those skilled in the art from a review of the following detailed description of my invention, reference being made to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Like reference numerals have been used to designate like parts in all figures. As shown in FIG. 1, the valve assembly includes a barrel housing 1 which may have an aperture formed therein in area 3 in which is mounted an injectable mesh material. The barrel housing 1 is connected to LEUR® lock assembly 2, 4 for connecting the universal valve to a urine collection bag. The narrower diameter stepped section 5 is the adapter interface used to connect the universal valve to the Foley catheter. Stepped section 5 is formed integrally with the flex body 7 and is the fluid input to the universal valve while section 2 is the fluid output from the universal valve.
FIG. 2 is a sectional view taken along the line 2-2 of FIG. 1. It shows the spring-loaded floating pintle seal valve 11 in its closed position. FIG. 3 shows the same seal valve 11 in its open position. As will be explained in detail below, the seal may be open or closed by squeezing the outer housing or by pulling and holding the LEUR® lock fitting, 2, 4.
In FIG. 2, numeral 5 shows the connector for connecting the Foley catheter (not shown) to the pintle seal assembly. Connector 5 is a stepped connector known as a catheter adapter and is used to connect the universal valve to the Foley catheter tubing. A sectional view of this connector is shown in FIG. 5. A pintle 11 is held into the central opening 13 of the catheter adapter connector 5 to close the opening 13. Pintle 11 is formed on walls 14, 15 surrounding moveable round member 16. Member 16 is moveable by manually squeezing actuating tongs 8 and 9 through flex body 7. Squeezing the tongs causes them to push the domed round member 16 downward against the force of compression spring 10, which in turn moves the pintle 11 from the closed position shown in FIG. 2 to the open position shown in FIG. 3. When the tongs are released, the spring 10 causes the pintle to return to its closed position.
FIG. 3 is a view similar to FIG. 1 showing the pintle valve 11 open. Tongs 8, 9 are shown covering the domed portion of round member 16. Spring 10 is shown compressed against the assembly retainer plug 21, shown in detail in FIGS. 10-10B, and the ledge portion 12 of the pintle valve. The closed position is maintained either manually, by hand pressure on serrated pads formed on flex body 7, 180° apart, or continuously held by the connection of LEUR® lock to its adapter for connection to urine collection bag.
FIG. 4 is a sectional view taken along the line 4-4 of FIG. 3 showing the top surfaces of tongs 8 and 9,
FIG. 6, is a sectional view of the LEUR® lock adapter 17 which fits onto connection 2, 4 of FIGS. 2, 3. When threadedly engaged, adapter 17 serves to hold the pintle 11 in the open position shown in FIG. 3. This is illustrated in detail in FIG. 7 where adapter 17 is threaded onto threads 3 and tightened to the position shown in FIG. 7. Numeral 18 denotes a section of tubing to connect the universal valve to urine collection bag.
FIGS. 8-8B show a sectional view of flex body 7, a bottom view of same (FIG. 8A) and a top view of same (FIG. 8B).
FIGS. 9A-9C show views of the actuator tongs 8, 9. Each tong is formed within a round base 19, for tong 8 and 20 for tong 9.
FIGS. 10-10B are detailed views of the retainer plug 21 of FIGS. 2-3.
Further modifications to the invention may be made without departing from the spirit and scope of the invention; accordingly, what is sought to be protected is set forth in the appended claims.
