  • the general functions that the master unit is preferably able to perform are listed herebelow. Details of the actions required to perform these functions are not included. Functions are grouped into the categories:- Operations utilising a personal spirometer unit. Phone line interface related. Data analysis and display. File support. All operations on a- directly connection spirometer may be performed on either of the two units that may be simultaneously attached to the master unit. One of these will normally remain permanently attached, for use in the doctors surgery, while another unit may be attached temporarily for initialising before being issued to a patient. Therefore, when connected to the master unit, the personal spirometer unit can perform the following functions. Set patient information in personal spirometer (see list of functions for spirometer in slaved mode);
  • the phone line interface of the master unit serves two purposes, firstly, to handle incoming calls from patients wanting to send the data content of their personal spirometer to be filed by the master unit. No intervention by the doctor is required.
  • the phone line function allows the master unit to accept the single sample data from a patients spirometer during a phone conversation with the doctor. As a result, it is necessary for the patient to be able to send a signal (to the master unit) that differentiates between the above cases. It is possible to use the personal spirometer to send this signal refer to the "header tone" state in the spirometer flowchart.
  • Chart patient history for selected parameter(s) over a selected period.
  • the file support should be capable of performing functions to initialise disk, empty directory, list directory, create patient file, delete patient file, load patient(s) file(s) to memory (either whole or a portion) (may hold more than one patients data in memory at once) , and, append data in memory to a patients file (checks patient name, etc. matches, and compares sample, date, etc. to avoid duplication) . Due to the wide variety of operations that the master unit must perform, it requires a considerable degree of versatility in its user interface.
  • the user interface planned for the master unit is of the "IMP" (Icons, Mouse and Pointer) -. variety. This is similar to portions of the system that has been success in the Apple Macintosh range of personal computers.
  • the system is a menu driven one, in which the menus appear on the master units LCD display or optional video output. Items in each menu consist of named pictographs that may be selected by pointing to then with the mouse, or alternatively by using the alphanumeric keyboard. The only operations that are normally carried out with the keyboard are the entry of patient names, addresses, phone numbers, etc. Other specific details of user interface operation may also be preferable.
  • the master unit firstly detects ring tone and answers (asserts OFF HOOK) . If header tone is present on line then master unit handles rest of data transfer itself (using voice or tone prompts to instruct the patient), or, if no header tone, the master unit prompts the patient to wait, while ringing the phone connected to the Line Out socket. When the phone is answered, the master unit switches the call through. During the conversation, the master unit may be switched back into the call to receive sample data from the patients spirometer.

  • Fig. 6 is illustrated a block diagram showing the major components of the master unit of the present invention.
  • the present invention provides a novel monitoring system for the monitoring of the condition of the lungs and/or bronchial tract of a patient, which can determine the presence of constrictions, restrictions or obstructions within the air tract system.
  • a monitoring system is particularly useful for sufferers of asthma.
  • the provision of a portable, hand-held monitoring unit enables the asthma sufferer to carry the unit and take readings, as required, to monitor his-her condition.
  • the advantage of such a system is the ability of the doctor to gather comprehensive statistics on a patient over a period of time, for instance, over a number of months or years, and to assess the effectiveness of treatments and or the effects of environmental or seasonal changes.
  • the Physician has the ability to program a threshold at which he considers the patient is in danger. When this threshold is reached, an alarm is activated to inform the patient to contact a doctor or administer some prescribed treatment as directed by the patients doctor. A further alarm may also be provided to remind the patient that it is time to again use the monitor - this may be programmed by the doctor, or be set to a specific time period.
  • the present invention will thus be seen to not only provide a 'warning' system to the user of the device, but also enable the collection of sample data from the various personal spirometers, which may be utilised by asthma researchers by conveying a wider sample population for a longer period and with greater accuracy, and which would obviously more closely reflect the normal conditions of various individuals than any other data previously available. Such data would, no doubt, be an enormous aid to asthma researchers.
