Definitions

  • the present invention relates generally to medical devices and, more particularly, to user interfaces and identification systems integrated with medical devices.
  • pulse oximetry For example, one technique for monitoring certain physiological characteristics of a patient is commonly referred to as pulse oximetry, and the devices built based upon pulse oximetry techniques are commonly referred to as pulse oximeters.
  • Pulse oximetry may be used to measure various blood flow characteristics, such as the blood-oxygen saturation of hemoglobin in arterial blood, the volume of individual blood pulsations supplying the tissue, and/or the rate of blood pulsations corresponding to each heartbeat of a patient.
  • Pulse oximeters and other medical devices are typically mounted on stands that are positioned around a patient's bed or around an operating room table.
  • a caregiver desires to command the medical device (e.g., program, configure, and so-forth) they manipulate controls or push buttons on the monitoring device itself.
  • the monitoring device typically provides results or responses to commands on a Liquid Crystal Diode (“LCD”) screen mounted in an externally visible position within the medical device.
  • LCD Liquid Crystal Diode
  • this conventional configuration has several disadvantages.
  • this conventional configuration relies upon physical contact with the monitoring device to input commands (e.g., pushing a button, turning a knob, and the like).
  • Such physical contact raises several concerns. Among these concerns are that in making contact with the medical device, the caregiver may spread illness or disease from room to room. More specifically, a caregiver may accidentally deposit germs (e.g., bacteria, viruses, and so forth) on the medical device while manipulating the device's controls. These germs may then be spread to the patient when a subsequent caregiver touches the medical device and then touches the patient. Moreover, if medical devices are moved from one patient room to another, germs transferred to the medical device via touch may be carried from one patient room to another. Even in operating rooms where medical devices are typically static, germs may be transferred onto a monitoring device during one surgery and subsequently transferred off the medical device during a later performed surgery.
  • germs e.g., bacteria, viruses, and so forth
  • medical devices that rely on physical contact for command input may create clutter the caregiver's workspace. For example, because the medical device must be within an arm's length of the caregiver, the medical device may crowd the caregiver — potentially even restricting free movement of the caregiver.
  • caregivers may have difficulty manipulating controls with gloved hands. For example, it may be difficult to grasp a knob or press a small button due to the added encumbrance of a latex glove.
  • HIPPA Health Insurance Portability and Accountability Act
  • conventional techniques for outputting medical data also have several potential drawbacks.
  • conventional techniques for displaying outputs rely on LCD screens mounted on the medical device itself. Besides constantly consuming power, these LCD screens must be large enough to be visually accessed by a caregiver. As such, the conventional LCD screens employed in typical medical devices also may be a barrier towards miniaturization of the medical device. Further, conventional screen-based output techniques may be impersonal to the patient and may lack configurability by the caregiver.
