1. An apparatus comprising:

  • a fluid reservoir;

    a compressible metering chamber comprising a first end coupled to the fluid reservoir and a second end, the first end comprising an unopposed fluid conduit for passage of a fluid between the fluid reservoir and the metering chamber;

    a deformable valve coupled to the second end of the metering chamber, the metering chamber having a flange between the first end and the second end;

    a substantially rigid nozzle coupled to the deformable valve; and

    a nozzle locking mechanism positioned around the metering chamber, between the first end and the flange, wherein the nozzle locking mechanism is removably attached to the nozzle and a longitudinally extending arm of the nozzle locking mechanism extends below the flange and is positioned within slots of the nozzle to secure the nozzle to the second end of the metering chamber, andwherein the nozzle defines a valve reservoir connected to a fluid outlet channel, and wherein the deformable valve is positioned within the valve reservoir and an opening or closing of the deformable valve controls a bidirectional fluid flow through the fluid outlet channel.
