Positive-pressure respirator
A positive airway pressure device is used to solve the problem of inconvenient use of the known positive airway pressure device and comprises: a tube including an inner end hole and an outer end hole intercommunicating with the inner end hole, with the outer end hole being smaller than the inner end hole, with the tube adapted to be inserted into a nasal cavity; and a two-way valve located in the tube, with the two-way valve moving axially between the inner end hole and the outer end hole, and with the two-way valve including a fluid passage intercommunicating with the inner end hole and the outer end hole.
1 . A positive airway pressure device comprising:
a tube including an inner end hole and an outer end hole intercommunicating with the inner end hole, with the outer end hole being smaller than the inner end hole, with the tube adapted to be inserted into a nasal cavity; and
a two-way valve located in the tube, with the two-way valve moving axially between the inner end hole and the outer end hole;
wherein the two-way valve includes a first end face and a second end face opposite to each other, the first end face being adjacent to the inner end hole, and the second end face being adjacent to the outer end hole, wherein the two-way valve further includes a fluid passage, which is a through hole extending through the first end face and the second end face to intercommunicate the inner end hole and the outer end hole.
2 . The positive airway pressure device as claimed in claim 1 , wherein the tube includes a tube body and a base, the tube body is coupled to the base, the inner end hole is located in the tube body, and the outer end hole is located in the base.
3 . The positive airway pressure device as claimed in claim 2 , wherein the base and the tube body together form a receiving space, the receiving space is located between the inner end hole and the outer end hole, and the two-way valve is located in the receiving space.
4 . The positive airway pressure device as claimed in claim 2 , wherein the tube body includes a coupling protrusion, the base includes a recessed portion, and the coupling portion is coupled in the recessed portion.
5 . The positive airway pressure device as claimed in claim 1 , wherein an outer diameter of the two-way valve is greater than a hole diameter of the inner end hole and a hole diameter of the outer end hole.
6 . The positive airway pressure device as claimed in claim 1 , wherein the two-way valve includes at least one first groove, and the at least one first groove intercommunicates with the inner end hole.
7 . The positive airway pressure device as claimed in claim 6 , wherein the at least one first groove is located on the first end face, and the at least one first groove extends along an outer wall of the two-way valve in a direction towards the second end face.
8 . The positive airway pressure device as claimed in claim 1 , wherein the tube includes at least one second groove, and the at least one second groove intercommunicates with the inner end hole.
9 . The positive airway pressure device as claimed in claim 1 , further comprising a film, with the film coupled to an outer peripheral wall of the tube.
10 . The positive airway pressure device as claimed in claim 9 , wherein the film is made of polyurethane material.
