A method for moulding an airway adapter (10, fig 1), the airway adapter comprising a flow path (20, fig 1) for fluid and integral windows (30, fig 1) to allow a measurement path to pass through the flow path, the method comprises injection moulding the airway adapter in a single shot moulding step. During the single shot moulding step, the windows are initially thicker than their final thickness and reduced to their final thickness by moving pins 200 that press the windows to their final thickness. An airway adapter comprises a flow path for fluid and windows for a measurement path through the flow path. The windows may be located on opposite sides of the airway adapter; the windows may be integral with the airway adapter forming one solid part of the airway adapter jointlessly and continuously; and the windows may have a thickness of less than 0.2 mm. The mould may include a first mould half 110 and a second mould half 120, a cavity 11 in the mould for filling with resin to mould the airway adapter, including cavity 31 for the windows. |
