Abstract: An infusion injection system wherein, when injecting a drug solution into a patient using an infusion set and an automatic infusion device, the automatic infusion device confirms various pieces of information regarding the infusion set in order to provide safe infusion for the patient, and to allow the user to assess the infusion information and manage a proper disposal procedure, wherein whether an infusion set is properly mounted is judged and if the judgment is positive, information stored in an IC tag attached to a drip tube 15 is read out by an IC tag reader unit 59 in an automatic infusion device 7, and information matching is verified between the read-out information and the information set beforehand for the automatic infusion device 7, and wherein control operations are performed only when the verification is a match.

Abstract: An infusion injection system is provided. When injecting a drug solution into a patient using an infusion set and an automatic infusion device, the automatic infusion device confirms various pieces of information regarding the infusion set in order to provide safe infusion for the patient, and to allow the user to assess the infusion information and manage a proper disposal procedure. In step (step 62), whether an infusion set is properly mounted is judged. If the judgment is positive, information stored in an IC tag attached to a drip tube 15 is read out by an IC tag reader unit 59 in an automatic infusion device 7, and information matching is verified between the read-out information and the information set beforehand for the automatic infusion device 7 as shown in step (step 65). Control operations in step (step 7) and after are performed only when the verification is a match.

Abstract: A fingertip tactile sense input device for a personal digital assistant capable of various input operations produced by a moving fingertip over projections recognized by the fingertip tactile sense. An input plate has a plurality of fingertip input projections and input control means that encodes an input signal when a projection is depressed. A fingertip can be moved over the input plate with the wrists fixed. The projections are disposed within a surface area outlined by an inverted generally egg-shaped curve C1 or C2, which is usable equally by the index fingertip of either hand.

Abstract: A liquid flow rate detector and controller having a microprocessor that senses the rate of drops falling in a monitoring balloon on a fluid tube. A light emitter/detector diode pair detects drops as they fall in the balloon, which are timed by the microprocessor. The device has first and second switches manufactured in a single small unit made of thin laminates. Each switch comprises an electrode and a contact point, mutually facing across a gap in the layers. The lamina on at least one side of each switch is elastic. External force flexes the elastic layer, causing it to bend across the gap, causing the electrode and the contact point to touch. A fluid tube is inserted in a narrow channel between the first switch and a movable wedge. A stepper motor under control of the microprocessor moves the wedge to press the fluid tube against the first switch until the contacts close. This indicates that the fluid tube is completely flattened and closed.
