Definitions

  • the present invention relates to a device for indicating a valve opening status according to the preamble of the main claim.
  • VPR valve with integrated pressure regulator
  • the VIPR typically comprises a valve and a handling device / guard.
  • '2 knob design' i.e. a safety shutoff valve (controlled by a handwheel) and used to isolate the valve from the high pressure cylinder, and a flowknob used to set discrete flow rates (typically in the range from 0.25 to 25 L/min).
  • the present invention provides a device for indicating a valve opening status according to the main claim.
  • Advantageous embodiments are subject-matter of the dependent claims as well as the following description.
  • a device for indicating a valve opening status comprises a manipulator, configured to change an opening status of a valve, and is characterized by an indicator, configured to display an information on the opening status of the valve, and a drive element, configured to effect a change of the information displayed by the indicator in reaction to a change of the opening status of the valve.
  • the manipulator is at least partially and/or temporarily covered by a cover, wherein the cover is configured to not cover the indicator at least when covering the manipulator.
  • the drive element preferably comprises a mechanism mechanically coupled to both the manipulator and the indicator, such that a movement of the manipulator effects a movement of the drive element and a movement of the drive element effects a change of the information displayed by the indicator. This means that by changing the valve opening status, the indicator automatically and reliably displays the correct information.
  • Said mechanism advantageously comprises a Geneva gear. This is a simple and robust mechanism and thus ensures proper displaying of the information required.
  • the manipulator preferably comprises a handling element of a gas container shutoff valve. Therefore, the indicator displays information on whether gas can be withdrawn from the container or not. This reduces the risk, for example, of setting a flow rate for gas withdrawal from an oxygen cylinder while the shutoff valve is closed. If that were done, a patient requiring oxygen might be harmed due to a lack of respiratory oxygen. Thus, the invention may save lives of patients with respiratory conditions requiring oxygen treatment.
  • the device further comprises a regulator configured to regulate a gas flow and/or a gas pressure.
  • a regulator configured to regulate a gas flow and/or a gas pressure.
  • the indicator is arranged adjacent to said regulator.
  • the indicator on setting a flow rate and/or pressure to be effective downstream from the device, it is immediately evident, if the valve is opened or closed, so that an operation error becomes very unlikely.
  • FIG. 1 an arrangement of an advantageous embodiment of a device according to the invention and a gas cylinder is shown.
  • the device is collectively referred to with 100, the gas cylinder with 150.
  • the device 100 comprises a connector port 130, a regulator 140, an indicator 120, a manipulator 110 and a manipulator cover 115, beneath which, as shown in Figures 2A and 2B , a manipulator 110, here in the form of a handwheel, is arranged.
  • a shutoff valve of the gas cylinder 150 can be opened and closed.
  • Figure 2A a situation with a closed valve is shown
  • Figure 2B a situation with an open valve is illustrated.
  • the handwheel 110 is connected to the indicator 120 via a drive element such as a mechanism, an exemplary embodiment of which is depicted in Figure 3 and collectively referred to with 200.
  • the mechanism 200 may comprise an indicating cylinder 210 which is rotatable around its vertical axis.
  • a rotation of the indicating cylinder 210 may be effected by a Geneva gear 230, which is in engagement with a knob 212 protruding in a direction perpendicular to the vertical axis from the indicating cylinder 210.
  • Rotational movement of the indicating cylinder may be limited, e.g.
  • the Geneva gear 230 may be directly coupled to the handwheel 110, for example via a common axis, or may engage with the handwheel via a transfer means such as a toothed gear, a belt or similar means.
  • the rotational movement of the indicating cylinder 210 may be aided and/or hindered by a torsion spring 216 or the like, so as to minimize play and/or required force.
  • the indicating cylinder 210 can have an indicating label, e.g. with colour and/or text and/or symbolic representations printed on the surface.
  • the label presented to the user e.g. through a window in a housing of the device 100, can indicate, for example, 'ON', showing the shutoff valve is open, or 'OFF', showing the shutoff valve is closed.
  • This information may additionally or alternatively colour coded and/or represented by symbols.
  • Said window in combination with the indicating cylinder 210 may form the indicator 120 mentioned herein before.
  • the indicator 120 could also be used to display a status where the valve is not fully opened or closed by showing a graduated colour, for example red-green.
  • the device 100 can also incorporate an electronic sensor (for example a hall sensor and/or a magnet) that monitors the drive element, e.g. the position of the Geneva gear 230.
  • the electronic sensor can also be used to trigger a misuse alarm condition (e.g. handwheel closed, flow rate set) which could activate an audible and/or visual alarm.
  • the indicator 120 may be arranged in different locations of the device, particularly in the vicinity of the regulator 140 and/or the manipulator 110. Particularly advantageous locations are outside an area covered by the cover 115, which may, for example, be attached for transport of fresh gas cylinders 150 and may be configured to be detached from the device, once it is in use, to indicate that a gas cylinder has already been opened.
  • the cover 115 may be reusable so as to provide an additional element of security for the manipulator. For example, it may be helpful to cover the handwheel 110 after it has been opened to provide a psychological barrier for closing it during a stressful situation.
  • the device 100 provides enhanced operating safety by clearly indicating the valve opening status at a location easily visible for a user at all times. This is of particular advantage in connection with medical gases such as oxygen, nitrous oxide or other therapeutic gases.
  • the device 100 or its mechanism 200 may be used in connection with new gas containers 150 or retrofitted to existing systems, thereby reducing investment costs and environmental impact.
  • the mechanism may at least partly consist of low cost materials such as thermoplastics, light metals or the like as well as combinations thereof.
  • mechanism 200 alone or the device 100 may also be used in connection with other valves and is not limited to gas cylinders 150.
