Abstract:
A mask assistor, comprising two air intake tubes (1) capable of being inserted into the nostrils. The two air intake tubes (1) are connected to one another by means of a connecting strip (2), and the air intake tubes (1) are each radially provided with an air outlet tube (3) that communicates with the air intake tubes (1); the air outlet tubes (3) are each provided with an air outlet one-way valve (4) that is turned on when a user exhales, and the air intake tubes (1) are each provided with an air intake one-way valve (5) that is turned on when the user inhales; the other end of each air outlet tube (3) far from an air intake tube (1) is provided with a clamp (6) that clamps a mask. The mask assistor has a simple structure, and is used in cooperation with an ordinary mask; the air outlet tubes (3) extend out from both sides of the ordinary mask; when a user inhales, air can only enter from the air intake tubes (1) after being filtered by passing through the ordinary mask; and when the user exhales, a gas can only be discharged from the air outlet tubes (3). As such, it is ensured that inhaled gas is fresh external air, the amount of oxygen inhaled is effectively guaranteed, the breathing of the user is smooth, and the mask assistor can be repeatedly used; in addition, the clamps (6) clamp the two sides of the mask, effectively preventing the mask from blocking outlets of the air outlet tubes (3).
