Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, an anti-exhaled air retrospective trachea structure comprises a body 1, which is provided with an air inlet 11 and an air outlet 12;

the air outlet 12 is provided with a first valve component 2;

the second valve assembly 3 is arranged between the air inlet 11 and the air outlet 12, the second valve assembly 3 comprises iron strips 31 distributed in a circumferential array and web pieces 32 bonded on the iron strips 31, the web pieces 32 and the iron strips 31 are in a circular truncated cone structure, and the circular truncated cone structure comprises an upper bottom and a lower bottom, wherein the lower bottom is specifically of a hollow structure and is distributed towards one side of the air outlet 12.

This body 1 design is keeping under the prerequisite of same route, and the shutoff of patient's expired gas accessible first valve subassembly 2 is discharged from gas outlet 12, and patient's throat's flesh can keep sufficient tension like this, avoids causing disuse atrophy because long-time throat's flesh is in the state of reposing, can realize taking phonation and speech to communicate under the tubulose state to conscious patient simultaneously. Furthermore, the second valve component 3 adopts an embedded design, the design ensures the consistency of the pipe diameter of the body 1, the movement of the sputum suction pipe in the body 1 is convenient, and the safety of the body 1 is ensured. Further, when the patient inhales, the first valve component 2 seals the air outlet 12, the second valve component 3 is always in a smooth state, and when the patient exhales, the air flow is exhausted from the lung and pushes against the bottom, so that the iron strip 31 is driven to turn over to seal the air inlet 11 by the force acting on the web sheet 32, and the first valve component 2 is sealed to ensure that the air inhaling process forms a closed environment so as to achieve the target inhaling pressure or inhaling capacity.

Further, the body 1 provided by the utility model is made of medical rubber.

Further, in the above embodiment, the web 32 is made of elastic silicone rubber, and the thickness thereof is 0.1-0.2 mm.

As the best embodiment provided by the present application, as can be seen from fig. 3, the second valve assembly 3 further includes a mounting ring 33, a cross connecting piece 34 is disposed at the center of the mounting ring 33, a protruding rod 35 is disposed at the intersection of the cross connecting piece 34, and the iron bar 31 is hinged on the protruding rod 35 and is driven by the torsion spring to maintain the circular truncated cone structure. Specifically, combine above-mentioned technical scheme, the iron sheet 31 group of this web piece 32 of subsidiary, whole be round platform structure, and go to the bottom for sunken, consequently when the patient breathes in, receive the torsional spring effect, it keeps on the state of "round platform structure", and gas is direct flows to going to the bottom from the upper base, and the gas flow pushes away makes the round platform structure shrink and be cylindrical structure to guarantee the air current passageway. When the user exhales, the lung discharges airflow, the airflow enters the recess, the force acting on the web sheet 32 drives the iron strip 31 to turn over to block the air inlet 11, and therefore the actual airflow cannot pass through the air inlet and can only be discharged from the air outlet 12.

In the technical solution provided in the present application, as can be seen from fig. 3, a connecting seat 121 is disposed on the gas outlet 12, and the first valve component 2 is installed on the connecting seat 121. Specifically, including mount pad 21 and silica gel piece 23, seted up the through-hole on the mount pad 21, and the outer wall of one side is provided with bump 22 between two parties, and silica gel piece 23 passes through bump 22 and installs on mount pad 21 to shelter from the through-hole. In short, when the exhalation is performed, the lung discharges the air flow, the air flow enters the recess, the force acting on the web sheet 32 drives the iron strip 31 to turn over to block the air inlet 11, so that the actual air flow cannot pass through, but the air flow flows towards the air outlet 12 and pushes up the silicon sheet 23, so that the through hole is exposed, and the air flow is discharged.

It should be noted that, in the above embodiment, the first flap assembly 2 is mounted by screwing the cover 6 into the port of the connecting seat 121, which is used for abutting against the convex point 22 to fix the mounting seat 21, which is common technical knowledge of those skilled in the art and will not be expanded in detail. And the sealing cover 6 is provided with corresponding air holes, and the air holes are provided with filter screens, so that external dust is prevented from entering the sealing cover.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the utility model.
