  • the present invention relates to a portable handheld terminal. More particularly, the present invention relates to a portable handheld terminal having integrated keypad, display, and optical bar code reader functions and further including electromagnetic transceiver means for wireless transmission of data to and from a base communications station. Additionally, the present invention relates to a portable handheld terminal having a novel handle design which facilitates ease of use.
  • bar code readers available on the market which provide for the collection of data for later downloading at a computer terminal.
  • An example of such a bar code reader is one used to take inventory.
  • the bar code reader will typically include memory for storage of the inventory data and a communications port for later downloading of the inventory data at the computer terminal.
  • Such bar code readers do not provide for interactive functioning with a computer system in full duplex fashion, i.e., enabling communication to and from the computer system.
  • Some bar code readers have been installed as a part of a microcomputer, e.g., by addition of a printed circuit board in one of the microcomputer's available slots.
  • bar code reader which can interactively communicate with the microcomputer
  • the bar code reader is physically wired or interconnected to the microcomputer and while the terminal may indeed be somewhat transportable from one location to another, it. is not intended for hand carried use.
  • Typical use of such a bar code reader and microcomputer arrangement might be that of a retail store such as a grocery store wherein items are being sold at a checkout counter.
  • bar code readers are not used in conjunction with integrated keyboard and display functions wherein the user can control operation of the bar code reader by use of the keyboard and wireless interactive communication with a main computer system.
  • a light source is typically used to. illuminate a bar code, which is a series of printed bars of various widths and spacing.
  • An optical detector "reads" the reflections from the bars and identifies them as a :code or; number.
  • a typical example of this technique is found at supermarkets, where a product's bar code is scanned and billed as it passes over the bar code reader at the checkout counter.
  • the bar code is "scanned” by causing relative movement between the bar code and the bar code reader.
  • the bar code reader might be moved relative to the bar code, or the bar code might be moved relative to the bar code reader.
  • the “scanning" of the bar code is necessary since the optical detector has a very limited range of detection along the X-axis or direction of movement or “scanning".
  • Two types of optical technologies often used in bar code readers are the light emitting diode (LED) and the laser. Because of their lower costs, relatively low power requirements, and safety, LEDs are more commonly used. However, due to the fact that LEDs emit a relatively low light level, bar code readers using LEDs must be held closer to the bar code and are often referred to as "contact” bar code readers. Contact bar code readers will typically use a bar code wand which is held in contact with the bar code and then move relative to the bar code.
  • Non-contact bar code readers are difficult to use on other than flat surfaces.
  • Non-contact bar code readers are rather focal specific and require a rather uniform scan rate and uniform distance between the bar code and the optical detector of the bar code reader.
  • lasers can present health risk and may be unsafe for use in various industries, particularly the health care industry. Also, lasers consume relatively more power and are relatively expensive when compared to LEDs.

  • pressing the left arrow key will provide for editing of the data. It will function as a backspace key, and the characters will be erased from the field as the key is pressed. If all characters in a field are erased by using the left arrow as a backspace, the cursor jumps to the first character in the previous field.
  • ENTER PAT DATA The "ENTER PAT DATA" is used to enter patient vital signs and patient assessment.
  • the formatted display will be presented at the liquid crystal display for entry of the vital signs and patient assessment.
  • REVIEW PAT HIST The "REVIEW PAT HIST" key is used to review patient vital signs and administrations.
  • the "DRUG CART" key is used to replenish and check out controlled drugs from the drug cart, and verify the drug cart inventory of controlled drugs.
  • ADMIN DRUG The "ADMIN DRUG" key is used for patient and drug verification for drug administration.
  • OTHER FUNC The "OTHER FUNC" key is used for patient and sample verification for taking of samples, billing for patient use of supplies, checking a patient into a new location, and displaying other functions which might be available on the system.
  • the liquid crystal display (LCD) 354 will also provide information relating to the LEDs.
  • the yellow LED 358a will be lit when the SEND key is pressed and win remain lit until communications with the base unit is complete. During this time, the user cannot make any entries at the keyboard.
  • a red LED 358b is lit when information entered for a function desired does not match what is the correct information for that function, or when an invalid key is pressed.
  • the red LED 358b is a warning not to proceed without first checking for a potential problem. The red LED will remain lit continuously under the first condition until some action is taken to remedy the problem. Under the second condition, the red LED will remain lit while the LCD displays the invalid key pressed message.
  • a green LED 358c is lit when a function is valid to proceed.
  • the green LED is lit momentarily under this condition.
  • the green LED is also lit when the central computer system acknowledges receipt of proper information.
  • the green LED is lit continuously under this condition until some other action is taken.
  • a yellow LED 358d will indicate the early warning of a low battery in the portable handheld patient terminal. This is an early warning level and the portable handheld patient terminal will still function. However, operation of the portable handheld patient terminal will be locked out when the batteries reach a level where the data in the patient history is corrupted.
  • the LCD display 354 will display a warning.
  • the LCD display 354 will be capable of displaying four lines of text each containing twenty characters.
  • the LCD will have a lighting source which will provide illumination under low light conditions. This lighting will be controlled by a key on the keypad switching the lighting source from the on to off or off to on condition. If the light source is on when the portable handheld patient terminal is returned to the base unit, it will automatically be turned off.
  • the preferred embodiment of the portable handheld patient terminal 320 will also make use of audible tones to a limited extent and include means to disable the audible tones. It will be appreciated that there are a number of situations wherein an audible tone or alert could be utilized. For example, 1) a single beep when a valid bar code read occurs, 2) three beeps when the red LED is lit, 3) three beeps when invalid key pressed, 4) three beeps when a bar code is successfully read but the data contained in the bar code does not meet the requirements for the field being displayed on the LCD display 354, etc.

Abstract

Le terminal portatif (20) pouvant être tenu dans la main comprend un appareil de lecture de code à barres optiques. Le boîtier (22) présente des première et seconde surfaces principales opposées espacées l'une de l'autre et s'étendant longitudinalement entre des première et seconde parties extrêmes (28, 30). Une partie faisant office de poignée (40) est reliée au boîtier (22) et s'étend longitudinalement le long de la seconde surface de manière à former une poignée pour tenir le lecteur de code à barres. De plus, le terminal portatif (20) pouvant être tenu dans la main comprend un lecteur de code à barres optiques utilisant un capteur d'image binaire et un émetteur-récepteur HF.
