Intended use:

The Hans Rudolph 6450 Disposable Mask is a single patient use mask intended for use with mask adapters, for connection with flow measuring instruments used in lung function testing procedures. The typical mouthpiece and nose clip is replaced by this face mask assembly and headgear. The masks and valves are supplied clean, non sterile. Typical applications are for pulmonary function testing, exercise testing and respiratory research. These mask valves are classified as reusable and can be high level disinfected.

Mask Application & Fitting

  1. Determine patient mask size with optional Mask Sizing Gauge.
  2. Place mask over patient’s nose and mouth. Chin should fit into mask chin cup portion with top of mask sealing area on the bridge of the nose.
  3. Slide headgear over patient’s head with one of the lower quick release strap clips disconnected. Reconnect headgear strap clip after headgear is mounted. Bottom straps should be positioned below ears and top straps above ears and below eyes.
  4. Adjust headgear strap tension by pulling slightly away from the face on strap end hook sections until tension is evenly distributed at all four straps with mask snug but comfortable. The strap clips lock and hold the position of the strap. To loosen the straps pull up on the back of the clip. Attach hook ends to the headgear fabric to keep the ends attached and out of the way. Adjust straps at crown of head by pulling each in opposite direction until reaching the required tension then connect Velcro.
  5. Push the flow meter patient side into the port opening in the flexible mask adapter

  1. Mount headgear to the face piece with the snap-in quick release clips.

Functional Check

  2. For function test hold pa

  3. Push the patient port side of the flow meter into the flexible mask adapter. It should fit snug and not fall out without significant pulling.
