Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, more technical details of the present invention are described in detail with specific embodiments below.
As shown in fig. 1 to 5, the speaking valve of the present embodiment comprises a check valve 1, a membrane 2, an adjusting member 3 and a tracheal cannula connector 4, wherein,
check valve 1 has the air inlet and with the inner chamber of air inlet intercommunication, and the air inlet of check valve 1 is provided with grid 11 and installation pole 12, and grid 11 uses installation pole 12 to be radial setting as the center, and installation pole 12 extends toward the inner chamber of check valve 1, is provided with the external screw thread on the installation pole 12.
The film 2 is used for opening or closing the air inlet of the check valve 1, the film 2 is made of elastic soft materials such as silica gel and the like, the film 2 is installed on the installation rod 12, the position of the inner cavity of the check valve 1 can be adjusted, the outer diameter of the film 2 is larger than the diameter of the air inlet of the check valve 1, and when the film 2 is completely unfolded, the film can cover the air inlet of the check valve 1.
Regulating part 3 is the part that is used for restricting 2 home ranges of film, regulating part 3 pastes in the one side that film 2 is close to tracheal cannula connector 4 mutually, the external diameter of regulating part 3 is greater than the external diameter of film 2, regulating part 3 is the cylinder structure, it forms the through-hole to dig in the middle of the cylinder structure, be equivalent to the ring structure promptly, regulating part 3 is provided with connecting portion 31 and follows the grid of connecting portion 31 to the 3 inner wall radiations of regulating part, connecting portion 31 protrusion regulating part 3 of this embodiment, connecting portion 31 has the screw thread through-hole, with installation pole 12 threaded connection, regulating part 3 can compress tightly to the air inlet direction of check valve 1 gradually, reduce film 2 and the air inlet clearance of check valve 1 gradually until locking film 2 becomes the shutoff state.
