<p>INFUSION CONTROLLING APPARATUS AND METHOD Portable electronic medical apparatus for controlling the flow rate of a fluid for medically treating a patient may receive flow rate information representing sequences of up to 20 flow rates and their durations from an individual and from an electronic data processor, and operate continuously without the presence of an operator for in the range of 40 hours. Upon the incorporation of an infusion pump into the apparatus, the desired regimen of treatment may be accomplished; and through a keyboard input for the apparatus, an operator may in certain respects modify a regimen which is being carried out. The apparatus may be used in a method of treatment including: coupling the apparatus to the processor; providing the apparatus with the flow rate information; decoupling the apparatus and processor; transporting the apparatus to the patient; coupling the apparatus to a supply of the fluid and regulating the flow rate of the fluid according to the information. It may be similarly used in a method including the providing of an electrical signal representative of a sequence of, e.g., at least 8 discrete fluid flow rates and their durations. The signal may then, if desired, be independent of changes in the condition of the patient during such providing. Safety features in the apparatus include: a frequency detector for monitoring the frequency of a clocking signal for the apparatus; the selective testing of output signals of the apparatus, the portable power supply for the apparatus and the frequency detector against stored predetermined standards; and the provision of warning signals to an operator to indicate divergences from such standards. Additionally, fail safe signals for the apparatus are coupled to relay circuitry to interrupt the output of the apparatus if a central processing unit for the apparatus enters undesired modes of operation.</p> |
