Abstract: The invention relates to an injection device for self-administration of doses of a liquid drug. The injection device carries a needle cannula (15) which is concealed by a telescopically movable shield (20). Further a stopping means (30) interconnects the shield with the helical rotatable scale sleeve (25) such that the shield can only be operated proximally when the scale sleeve is rotated away from its zero position. Once the scale sleeve returns to its zero position during expelling of the dose, the shield and the stopping means is allowed to slide distally and thus return to the locked position.

Abstract: A patient in intensive care is monitored by connecting the outputs of a plurality of sensors to a computer, where the sensors all relate to one mode of functioning such as heart beating, respiration, infusion of a liquid into the patient, etc. The sensor outputs are delivered to a computer that sounds an alarm, only if all sensors that indicate one function (e.g. heart beating) indicate dangerously low operation of that function. This avoids many false alarms caused by one sensor having a low output such as due to accidental disconnection of a wire.

Abstract: Parameters for controlling a drug infusion pump (10) are selected by scrolling through sets of predefined values. A value for either a rate and/or a volume of a fluid to be infused (VTBI) is displayed by pressing a quickset key (38) on a control panel (18) of the pump. Each time that the quickset key is depressed, the value appearing on a display (22) changes to the next value in the corresponding predefined set of values. It is also contemplated that holding the quickset key depressed for at least a predetermined time will cause the display to continuously scroll through successive values from the set of predefined values. The predefined values are selected in the set because they represent the most common values for the parameters used by the pump. An operator can "fine tune" the displayed value to a desired value that is not in the set of predefined values by pressing either a down arrow key (50) or an up arrow control key (52).

Abstract: In a liquid dispensing system, two pouches containing a liquid to be dispensed are connected by tubing to a reservoir and positioned at different levels above the reservoir. As the liquid is dispensed from the reservoir, the higher of the two positions is emptied and replaced with a filled pouch. The pouches are then reversed, with the new pouch in a lower position. When the other pouch is empty, it is replaced and the positions of the two pouches are again reversed. As a result, a continuous supply of liquid is dispensed from the reservoir. Any bubbles which are introduced into the system when the pouches are changed are automatically allowed to escape the system via a liquid level indicator line. A second level indicator provides an alarm or other signal should the liquid fall to the level of the reservoir.
