Description

COMBINED SUCTION AND GAS DELIVERY APPARATUS
The present invention concerns a combined gas delivery and suction unit, in particular a combined oxygen delivery and suction unit.
The supply of oxygen and suction to a patient is very important in a medical environment. In particular, the supply of such resources must be continuous and dependable - the failure of suction or of oxygen supply at a critical moment can be disastrous. Similarly, it must be conveniently provided and be readily transported with the patient, for example in an emergency situation when a patient is transferred from an ambulance to a surgical environment, or where a patient is transferred from ward to theatre and back. The currently available systems are cumbersome and inconvenient, requiring effort to move them with a patient.
According to the present invention there is provided a combined gas delivery and suction unit comprising a gas flow controller and a Venturi suction regulator connected to a gas source, the gas flow controller and the Venturi suction regulator being mounted on or forming part of a unit which in turn may be mounted upon or form part of a patient transportation unit, the unit comprising a common manifold for the gas flow controller and the Venturi suction regulator and being connected to the gas source.
The provision of a single unit supplying both gas and suction to a patient, the unit being attachable (or forming part of) a patient transportation unit allows the automatic movement of gas supply and suction with the patient. Accompanying hoses and tubes may be minimised and stored safely such that they do not pose a hazard, in contrast to existing arrangements which may have trailing hosing and tubes. Furthermore, the single combined unit may save time when moving the patient and may save gas since only a single gas supply is ever required.
The gas source may comprise a gas cylinder having a gas cylinder pressure regulator.
The Venturi suction regulator may be connected to a suction jar. The regulator may have an anti-bacterial filter. Suction may be at for example 850 mbar. The suction jar may have a capacity of about 1 litre. In order to provide for the sterility of suction jars, they may for example be autoclaveable or may have disposable liners.
By "patient transportation unit" is meant anything which is used to transport a patient. Hence the patient transportation unit may comprise for example a patient trolley, a bed or an operating table.
The gas may be oxygen.
The gas flow controller may be a solid state gas flow controller. It may have a user- variable flow rate. The flow rate may for example be varied within a range of about 0-15 litres per minute.
The unit may also comprise attachment means for attaching to the patient transportation unit a gas cylinder and/or a suction jar. The unit may also comprise an additional gas supply socket, for example to supply oxygen to a ventilator unit. The socket may of course have a gas flow controller.
The unit may be mounted upon a patient transportation unit for example by means of a clamp, which may allow for mounting upon different patient transportation units having different dimensions and configurations. Alternatively, the unit may be mounted upon a patient transportation unit for example by means of a specialised fitting.
The invention will be further apparent from the following description, with reference to the figure ofthe accompanying drawing, which shows, by way of example only a plan view of a combined gas delivery and suction unit.
The combined gas delivery and suction unit comprises a solid-state gas flow controller (Flowmeter, Flotec Inc., US) 10 and a Venturi suction regulator 20 connected to a gas source 30,31, the gas flow controller 10 and the Venturi suction regulator 20 being mounted on a unit 40 which in turn is mounted on or forms part of a patient transportation unit (not shown), the unit 40 comprising a common manifold 41 for the gas flow controller 10 and the Venturi suction regulator 20 and being connected to the gas source 30,31.
Tube 1 1 allows oxygen to pass to the patient.
The gas source 30,31 is connected by connecting tube 50 to the combined manifold 41 and comprises an oxygen cylinder 30 having a pressure regulator 31. The Venturi suction regulator 20 is connected by connecting tube 60 to a suction jar 70. Tube 61 then allows suction to be applied to the patient.
Oxygen flows from the oxygen cylinder 30, its pressure being controlled by pressure regulator 31, through connecting tube 50 and enters the combined manifold 41 ofthe unit 40. If required, oxygen then flows through the gas flow controller 10 at the selected rate to the patient through tube 11. Similarly, if required oxygen flows through the Venturi suction regulator 20 to create suction through tube 61 , suction jar 60 and connecting tube 60.
It will be appreciated that it is not intended to limit the invention to the above example only, many variations, such as might readily occur to one skilled in the art, being possible, without departing from the scope thereof.
