DESCRIPTION OF ATTACHED APPENDIX

BACKGROUND OF THE INVENTION
This invention relates generally to the field of medical and more specifically to an apparatus to empty urinary drain bags using wireless remote control technology. Historically, wearers of urinary leg bags were often confined, usually to a wheelchair or bed, limited in mobility and dependent on an attendant to assist them in emptying their bags, causing lack of proper fluid intake resulting in ill health effects and physical discomfort. Typical emptying mechanisms were manually operated by the user or by an attendant, or a hard-wired mechanism only usable in a stationary location, restricting user mobility.
PRIOR TECHNOLOGY
The most widely used drain bag emptying device includes a common clip attached to a flexible drain tube that is unclipped to an opened position to drain the bag through the tube and then clipped to a closed position to stop the draining. This operation often requires bending and stretching by users, thus limiting users that are unable to bend or stretch or otherwise perform this task to rely on an attendant to perform the task for them. Another available mechanism uses a switch that is hard wired to battery, usually a wheelchair motor battery. The switch is also hardwired to a solenoid operated pinch valve that is worn by the user. Upon activating the switch, the solenoid pinch valve releases to an open or on position draining the bag and is returned to its closed position when switched off. Because the switch is hard wired to the battery, the user must be disconnected from the mechanism when the user moves to another location such as a bed, car, boat or push wheelchair. This limits the operation of the mechanism to its fixed location, severely impairing the mobility of the user.
Another mechanism uses pressure sensor and timing technology for the purposes of bladder recycling or for other medical use.
DEFICIENCY OF PRIOR TECHNOLOGY
The prior technology is deficient in that the mechanism uses pressure sensor and timer technology for the purpose of bladder recycling.
The prior technology is deficient for leg bag emptying application because it is pressure sensitive and/or on a timer, thus causing inconvenient emptying of bag, limiting users mobility and control (Flinchbaugh publication date Oct. 3, 2002, #US 2002/0139419-A1).
The invention does not control or affect bladder recycling, but provides an external means for emptying a leg bag of urinary content via a flexible tube using remote controlled technology. The invention is operated and controlled by the wearer or by an attendant that can operate the mechanism from a distance. There is no pressure sensor or preset timing or other automatic function to engage its operation. Further, the invention is portable and can be worn inconspicuously by the wearer for ease of mobility and aesthetics.
Further, hard-wired mechanisms limit the mobility of the user to the location where the mechanism is mounted, usually to a wheelchair motor battery, limiting its operation only from the wheelchair or a fixed location. These mechanisms are often cumbersome.
BRIEF SUMMARY OF THE INVENTION
The primary object of the invention is to provide a practical and convenient means to empty a urinary drain bag that allows more freedom of movement, ease of operation, and portability encouraging more fluids to be consumed, therefore increasing good health, comfort and quality of life.
A further object of the invention is to provide mobility for the user by providing a portable and compact apparatus worn by the user, allowing the user to move from a wheelchair to a vehicle, boat or other location and to continue to operate the apparatus from any location.
Another object of the invention is to provide through the use of wireless remote control technology the means of operation to be self operated at a distance by an attendant.
Another object of the invention is to provide a small and compact battery operated system.
A further object of the invention utilizers a battery eliminator that plugs into a typical receptacle to provide power to the mechanism when adapted to a stationary use.
A further object of the invention is to provide the ability for the battery to be charged in most vehicles or a standard electrical outlet.
Another object of the invention is to prevent accidental operation of device causing unwanted discharge from leg bag. The transmitter button must be pressed continuously for a few seconds to engage operation of solenoid to drain the leg bag.
Another object of the invention is to provide the option for the device to be mounted in any suitable location or to be worn in a discreet manner.
Other objects and advantages of the present invention will become apparent from the following description, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed an apparatus to empty urinary drain bags using wireless remote control technology comprising: a solenoid operated pinch valve, connector, remote transmitter, receiver relay, circuit board, rechargeable battery, battery charger connector, battery eliminator, necessary wiring, and flexible tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed description of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
A portable urinary drain bag apparatus utilizing wireless remote control technology, in accordance with the present invention, turning first to FIG. 1, there is shown a suitable remote control transmitter device as shown in element 1, comprising “on” and “off” switch capability as shown in elements 18 & 19, that when the button is pushed to the “on” position as shown in element 18, a signal is sent to a wireless receiver relay as shown in element 2, which then transfers power from a rechargeable battery as shown in element 7, comprising of a battery connector as shown in element 6, connected through a battery connector as shown in element 17, wired to a commonly used terminal board as shown in element 5, which through a negative common connection as shown in element 15, a positive input connection as shown in element 14, and a positive output connection as shown in element 16, transferring power to a solenoid operated pinch valve, as shown in element 9.
In accordance with th important feature of my invention, the remote transmitter shown in element 1, when activated “on” sends a signal to the receiver relay shown in element 2, and through its connection to the terminal board as shown in element 3, opens the solenoid pinch valve as shown in element 9, releasing its pinched position on a flexible tube, as shown in element 10, which is connected to an outlet in a common urine drain bag, as shown in element 8. When the wireless remote transmitter as shown in element 1, is pushed to the “off” position as shown in element 19, a signal is sent to the wireless receiver relay as shown in element 2, which then de-energizes the relay, disconnecting the battery as shown in element 7, returning the solenoid pinch valve as shown in element 9, to its pinched, normally closed position on the flexible tube as shown in element 10, stopping the emptying of the bag as shown in element 8, allowing the bag to refill. If the operator fails to push the “off” button as shown in element 19, the wireless receiver relay de-energizes the solenoid returning it to its normally closed position. The circuit is protected by a fuse as shown in element 12. The battery can be recharged by connecting a suitable battery charger to a connector as shown in element 11. If the apparatus is used in a fixed location for an extended period of time, a suitable step down battery eliminator can be used by connecting at the battery connector as shown in element 17, in lieu of the battery as shown in element 7. The connected apparatus can be fitted together in a wearable pouch, vest or otherwise suited to the wearer for ease of movement and discreet appearance.
