Retractable protective respiratory mask

Abstract

A retractable protective respiratory mask including disposable filters, which protects the respiratory system, covering the nose and mouth during inhalation while breathing in an atmosphere polluted by different agents, such as infectious, virulent, or pathogenic agents, or other toxic substances. The mask also protects non-infected persons from persons infected with a virus, as saliva and sputum expelled when coughing, breathing-out, and/or talking can be deposited inside the mask. The mask can include a collection-container filter, allowing a viral-infected wearer to breathe in a polluted atmosphere, to talk, to cough, to sneeze and/or to deposit saliva and sputum. The mask can be used as any other type of filter mask and/or disposable environmental air mask for industry in general, and also providing protection in rarefied natural atmospheres. The mask can be used as a container or packaging for drugs administered by means of bronchial airways, or as medical or rescue masks.

Retractable protective respiratory mask device according to  claim 1 , characterized in that it has a rod ( 5 ) with pins ( 7 ) at each end of each of the doors ( 2 ) that connects the two doors by its sides with the difference of the pins at 90° from over the line of its axes with the other allowing the two doors to be opened or closed at the same time by only opening or closing either of the two doors 
     
     
         3 . Retractable protective respiratory mask device according to  claim 1 , characterized in that each of the two doors ( 2 ) at each of its edges molding half into a pear shape, for when opening the full pear shape, complemented with the filter bag ( 10 ) in the spaces ( 13 ) where it is shaped around the nose 
     
     
         4 . Retractable protective respiratory mask device according to  claim 1 , characterized in that each of the two doors ( 2 ) have grooves ( 12 ) before the edge so that when they open they may assemble the disposable collector filter bag ( 10 ) through the rubber ( 11 ) on its edge completing in this way the pear shape. 
     
     
         5 . Retractable protective respiratory mask device according to  claim 1 , characterized in that a disposable collector filter bag ( 10 ) goes on its inside with folds ( 14 ) creating the rectangular shape on its base, with rubber ( 11 ) on its edge, that makes it permanently closed. 
     
     
         6 . Retractable protective respiratory mask device according to  claim 1 , characterized in that it has mechanical means to push either of the two doors using a rod ( 19 ) that connects the door and the sealer ( 4 ) that when it activates it pushes the rod ( 19 ) and the latter pushes one of the doors so that both open. 
     
     
         7 . Retractable protective respiratory mask device according to  claim 1 , characterized in that it has double or single racks ( 36 ) above or below on the plungers ( 4 ) where those that cause the rack teeth  37  of the doors and the arm ( 44 ) to rotate when it enters or exits the plunger ( 4 ). 
     
     
         8 . Retractable protective respiratory mask device according to  claim 1 , characterized in that it has an arm ( 44 ) that pivots within the housing and rotates through the gear teeth of the pinion ( 38 ) which runs on the double rack ( 38 ) with pins at its end ( 40 ) which are those that push the sliding filter cover ( 41 ) through its grooves ( 39 ). 
     
     
         9 . Retractable protective respiratory mask device according to  claim 1 , characterized in that it has a sliding filter cover ( 41 ) which runs along the guide ( 42 ) of the housing of the retractable protective respiratory mask ( 1 ) and has grooves ( 39 ) where the pins ( 40 ) enter from the arms ( 44 ) 
     
     
         10 . Retractable protective respiratory mask device according to  claim 1 , characterized in that according to  claims 1  and  3 , characterized in that the doors ( 3 ) are activated because it has an electromagnet powered by a battery and controlled by a sealing connector. 
     
     
         11 . Retractable protective respiratory mask devices according to  claims 1 , characterized in that the doors ( 3 ) are activated by the pneumatic plunger that is connected between the housing and either of the doors activated by a bellows or diaphragm plunger connected directly to the sealer which transmits pressure to the sealing plunger through a hose. 
     
     
         12 . Retractable protective respiratory mask devices according to  claim 1 , characterized in that the doors ( 3 ) are activated by the hydraulic plunger that is connected between the housing and either of the doors activated by another plunger, connected directly to the sealer which transmits pressure to the sealing plunger through a duct. 
     
     
         13 . Retractable protective respiratory mask device according to  claim 1 , characterized in that the doors ( 3 ) are closed through the action of the springs ( 21 ) ( 28 ) and ( 35 ) which cause the doors to return to their site of origin ( 2 ) with different opening means once the plunger ( 8 ) stops being activated and/or when located within the actuating electromagnet ( 22 ) and/or inside the pneumatic ( 27 ) and hydraulic ( 30 ) plungers. 
     
     
         14 . Retractable protective respiratory mask device according to  claim 1 , characterized in that it has a pin ( 33 ) which upon being introduced, locks either and/or both doors to leave them open in case one wishes to use it open like an ambient air filter mask or closed to leave it locked while it not being used and it is being transported. 
     
     
         15 . Retractable protective respiratory mask device according to  claim 1 , characterized in that this device may be used as packaging for medications or as a medical equipment mask for human use for medicines that require devices such as masks, of application in the bronchial passages, respiratory or cardiac system.
