Claim 3:
4. The blood pressure device according to claim 1, wherein the valve device comprises:
a convergence plate having a convergence outlet and a guiding channel in communication with the convergence outlet, wherein a plurality of convergence plate assembly areas is defined on the convergence plate, and each of the convergence plate assembly areas has a convergence trough, a convergence plate convex portion, a discharge trough, and a discharge outlet, wherein the guiding channel communicates with the convergence trough in each of the plurality of convergence plate assembly areas, and the guiding channel is in communication between the convergence trough and the discharge trough in each of the plurality of convergence plate assembly areas, and wherein the convergence plate convex portion protrudes from the discharge trough, and is surrounded by the discharge trough, and wherein the discharge outlet is disposed at a central portion of the convergence plate convex portion;
at least one chamber plate, wherein the convergence plate is disposed on each of the at least one chamber plate, wherein a flow guiding chamber and a receiving trough are disposed in a portion of the at least one chamber plate corresponding to each of the plurality of convergence plate assembly areas of the convergence plate, wherein the flow guiding chamber and the receiving trough are respectively disposed on two opposite surfaces of the at least one chamber plate, and the flow guiding chamber corresponds to the convergence trough of the convergence plate and is in communication with the convergence trough, wherein a confluence chamber is disposed on a bottom of the receiving trough, and at least one communication hole is disposed on a bottom of the confluence chamber to communicate with the flow guiding chamber, and wherein a chamber plate convex portion is disposed in the flow guiding chamber and is surrounded by the at least one communication hole, and wherein a second communication hole is disposed on a portion of the at least one chamber plate corresponding to the discharge trough of each of the plurality of convergence plate assembly areas of the convergence plate, and the second communication hole is in communication with the confluence chamber; and
at least one valve sheet, wherein the at least one valve sheet is between the convergence plate and the at least one chamber plate, and the at least one valve sheet correspondingly abuts against the chamber plate convex portion in the at least one chamber plate, wherein a valve hole is disposed on the at least one valve sheet and corresponds to the chamber plate convex portion, and the valve hole is closed by the chamber plate convex portion, and wherein the at least one valve sheet abuts against the convergence plate convex portion in each of the plurality of convergence plate assembly area of the convergence plate to close the discharge outlet;
wherein the gas transmission device is positioned in the receiving trough of the at least one chamber plate so as to close the confluence chamber and so as to operate to transmit gas into the confluence chamber; and wherein when the gas transmission device operates, the gas transmission device guides the gas into the valve device from the confluence chamber of the at least one chamber plate so as to push the valve sheet to detach from the chamber plate convex portion, whereby the gas passes through the valve hole of the at least one valve sheet and flows into the convergence trough of the convergence plate in communication with the flow guiding chamber, and the gas is converged at the guiding channel and discharged out from the convergence outlet.
