Having Liquid Level Indicator Patents (Class 604/260)
  • Patent number: 10213563
    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.

  • Patent number: 9066750
    Abstract: A method of deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening. The invention also includes a system for practicing the method.

    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: In one aspect, the invention provides methods and apparatus for delivering peritoneal dialysis (PD) solution (or other fluids), from a supply to a patient. A first pump, in fluid coupling with the supply, delivers PD solution from the supply to a “mesne” (or intermediate) measuring element, and generates signals indicative of a volume of that delivered PD solution. The mesne measuring element, in fluid coupling with the first pump, generates signals indicative of a volume of PD solution received from that pump. A second pump, fluidly coupled to the mesne measuring element, routes PD solution from the mesne measuring element for delivery to the patient.

The pump includes a housing having an inlet and an outlet. The inlet and outlet alternate between an open and a closed state to deliver the medication. A port extends from the base. The port fluidly communicates with the reservoir and the pump during sterilization to provide access for the fluid to flow into the reservoir and the pump. An actuator is disposed in the base. The actuator operatively engages the inlet and outlet to retain them in the open state during sterilization. As such, the fluid can penetrate into the reservoir, the inlet, the housing, and the outlet to sterilize the system.

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).

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.
