Respirator
A breathing apparatus, including a mask and a neck component. The mask is adapted to substantially surround at least the mouth or nostrils of a user. The neck component is attached to said mask, and adapted to substantially surround the back of the neck of said user. The neck component includes a flow generator to receive unfiltered air from a surrounding environment, filter said unfiltered air, and, provide filtered air to said mask. The breathing apparatus has a ‘low profile’ appearance and is adapted to sit comfortably about the neck of the user.
1. A breathing apparatus, including:
a mask adapted to substantially surround at least the mouth or nostrils of a user; and
a neck component, adapted to substantially surround a rear portion of a neck of the user, further including a flow generator to receive unfiltered air from a surrounding environment, filter said unfiltered air, and provide filtered air to the mask, the neck component releasably engaged with the mask by at least one cooperating mating clip including an adjustment mechanism for moving and retaining the mask relative to the neck component;
an inlet air channel arranged to convey air from the flow generator to the mask; and an air outlet, separate from the air inlet channel, arranged to convey air from the mask, wherein the mask and the neck component each include a portion defining part of the inlet air channel, and wherein the at least one cooperating mating clip releasably engages the portions, forming a seal therebetween.
2. A breathing apparatus as claimed in claim 1 , wherein the inlet air channel is at least partly formed of an elastomeric material.
3. A breathing apparatus as claimed in claim 1 , wherein the adjustment mechanism includes a ratchet mechanism and a release mechanism, and wherein the ratchet mechanism is decoupled upon activation of the release mechanism, thereby allowing the mask to move relative to the neck component.
4. A breathing apparatus as claimed in claim 1 , further comprising electronic componentry configured to effect operation of the flow generator, wherein all the electronic componentry configured to effect operation of the flow generator is arranged within the neck component.
5. A breathing apparatus as claimed in claim 1 , further including at least one of a cover, to decorate said mask, and a visor, to protect a face of the user.
6. A breathing apparatus as claimed in claim 1 , further including a strap, adapted to be attached over a head of the user, to retain the mask in position.
7. A breathing apparatus as claimed in claim 1 , further including at least one of a flow sensor and a pressure sensor, the flow sensor and pressure sensor configured to provide a feedback signal to the flow generator to adjust at least one of air flow and air pressure of the mask.
8. A breathing apparatus as claimed in claim 1 , wherein the apparatus further includes a filter.
9. A breathing apparatus as claimed in claim 1 , wherein the neck component further includes at least one padded portion arranged to abut the neck of the user.
10. The breathing apparatus as claimed in claim 6 , wherein the inlet air channel and the air outlet open to the mask at opposite sides of the mask, so that the airflow is arranged to flow across the mouth or nostrils of the user.
11. A breathing apparatus as claimed in claim 1 , further including an exhaled air filter arranged to filter air emitted from the air outlet.
12. A breathing apparatus as claimed in claim 11 , wherein the exhaled air filter is integrally formed with an exhaust port.
13. The breathing apparatus as claimed in claim 11 , wherein the air outlet extends between the mask and the neck component and includes an exhaust port arranged proximal to the neck component.
