Medical personnel and patient communication indicator device
BACKGROUND OF THE INVENTION 
     Close cooperation and good coordination between medical personnel and patients is a basic factor contributing to optimal diagnosis and treatment. To achieve this end, the most important condition is that medical personnel including doctors, nurses, administrators) and patients (including accompanying friends and relatives) must be able to have timely communications. Patients should be able to timely and accurately express one&#39;s own sensations, experience and reactions. Such information is the most important link to diagnosis and treatment. Similarly, medical personnel by rules and regulation should be able to give proper directions, and explanations to patients and their relatives and solve patient&#39;s problems and needs. 
     However, as a result of language barriers or extreme physical weakness resulting in inability to make adequate volume in speaking or to articulate clearly, communication difficulty often arises in hospitals, nursing homes and rehabilitation centers. Delays and misunderstandings in communication reduces therapeutic effectiveness, delays in therapy, unnecessary incidents, and in the case of medical emergencies, the detrimental effects are even more obvious. 
     In order to reduce such regretful incidents, the inventor has designed a convenient, easy to operate and effective &#34;communication display indicator.&#34; 
     SUMMARY OF THE INVENTION 
     Concise data for informational exchange between medical personnel and patients is displayed on L C D screen or video screen, plus numerous other methods. The current model employs the simplest, inexpensive , easily controllable electrically lighted display. 
     This invention consists of 3 parts 
     1. A unit that displays information patients want to express This unit is called INFORMATION - UNIT A. 
     2. A unit that displays information medical personnel want to express. This unit is called INFORMATION - UNIT B. 
     3. Accessories connecting A and B.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     Fig. 1 
     3 - Dimensional Exploded View of the Whole Invention 
     Both INFORMATION - UNIT A and INFORMATION - UNIT B consists of a rectangular box, dimensions as specified in diagram. On the right edge is a hinge 1 enabling the box to be opened for change of spare parts inside the box e.g. informational screen 8, burned - out light bulb , and spent dry - cells 20 etc, and when the box is closed, the clasp 2 on the top - side of INFORMATION - UNIT A and the underside of INFORMATION - UNIT B each has sleeve - type jaws combining to form hinge and coupling 3 and 4 connecting INFORMATION - UNIT A and B together. Locking clamp screw 5 controls the angle that a INFORMATION - UNIT A and B to open like a book. 
     INFORMATION - UNIT A and B are enclosed in light, comfortable and beautiful casing 21, On the right and left side of the top of INFORMATION - UNIT A and B, are a row of touch buttons, which are actually on off switches 11 activated by light touch only, specially designed with consideration for the impaired physical, mental and visual power of patients. 
     On the top surface is a magnifying and protective transparent pane 22 Inside the pane is a rectangular information screen 8. On the information screen 8 are several transparent information cards 10, detailed in DIAGRAM 3 and DIAGRAM 4. 
     To access or change the information contained in the device, the user must rotate the two ends of the information screen 8, which houses a pair of rollers 25, similar to the pair of film rollers in a camera the informations screens data can be rolled back and forth by a winder 26 at the end of the rollers. The film can be removed and change like a roll of camera film, allowing unlimited amount of data for display by this device. 
     To use this invention in DIAGRAM 1, first light up the complete information screen, then, select the individual data card reflecting the person&#39;s idea. Also, one can make different cards to serve different purposes, e. g. A card for child education; a card for the mentally retarded population; testing service; learning toy etc, are all within the scope of this invention. 
     Each touch button 11 controls a separate tiny light bulb 6 in a socket 7 under the informational screen 8. Each tiny light bulb has a reflector 9, and when turned on by the appropriate touch button 11, can separately light up an information card 10. In addition, there is a central light 19 controlled by switch 12 that can light up the entire information screen 8. However, individual information card 10 can be further more brightly lit by touch - button 11 . 
     On the top right hand corner of both INFORMATION UNIT A and B, there is a socket 14 for wired connection to the central nursing station 24 Switch 13 activates socket 15 and signals the central nursing station 24 There is also remote control emitter 16 and receiver 17 for the same purpose. 
     In the bottom of INFORMATION - UNIT A and B are compartments for battery packs 20 and conducting clamps 18. 
     FIG. 2 Circuit Diagram 
     Circuit diagrams of INFORMATION - UNIT A and B are identical. 
     Switch 11 controls a tiny light bulb arranged in parallel on power source 20 
     In addition, there is a connector to the central nursing station 24, either wired 14, 15 or wireless 16, 17. 
     Telephone or intercom can also be connected to this device. 
     FIG. 3 Diagram 3 demonstrates INFORMATION - UNIT A unit in combination with INFORMATION - UNIT B, and A separating from B . An accessory sleeve - type jaw 3 and 4 combines A and B together, and also enables A and B to be separated. The angle of frame support 23 can the adjusted using locking clamping screw 5 so that INFORMATION - unit A and B can be angled properly to accommodate different individual circumstances. 
     OPERATING INSTRUCTIONS 
     To use this medical personnel patient communication device, INFORMATION - UNIT A and B are normally closed, so, open it up. Then, adjust 5 so that A and B are now adjusted to proper position. Adjust support frame 23 to proper angle to separate A and B, for separate usage. 
     Press button 12 to turn on lighting 19. The whole information screen 8 is now lit. The user can see all of the information contents clearly. Then, select the particular item one wants to express. By pressing one or more buttons 11 adjacent to data segments 10 The tiny light bulbs 6 controlled by these buttons now light up and the corresponding data segments are now brightly lit If a patient wants to talk about his headache, he presses button 11 next to the headache data segment and that segment brightly lights. The medical personnel knows at once the patient has headaches. Pressing button 11 once more will turn it off.
