As shown in fig. 3, the communication assembly 2 may further include an air inlet/outlet check valve 2131 disposed in the third port 213, and the air inlet/outlet check valve 2131 is used for blocking or opening the third port 213.
It can be understood that, in a natural state of the air inlet/outlet check valve 2131, that is, in a case where no pneumatic connector is connected, the air in the auxiliary air bag 22a cannot be directly discharged through the air inlet/outlet check valve 2131, and the air acts to maintain the pressure of the fixed air bag 21a, and after the pneumatic connector on the air charging/discharging device or the device is connected to the third port 213, the pneumatic connector pushes the air inlet/outlet check valve 2131 to open, so that the air charging/discharging device can charge and discharge the air into and out of the fixed air bag 21a, and after the connection is released, the pressure of the fixed air bag 21a is also kept constant by the air inlet/outlet check valve 2131.
It is also understood that the air inlet/outlet check valve 2131 may be a gas check valve commonly known in the related art, or may be a pneumatic connector commonly known in the related art, specifically, in order to prevent gas leakage from the airbag 20a when the gas charging/discharging device or apparatus is not connected, and to open the communication between the airbag 20a and the gas charging/discharging device when the gas charging/discharging device or apparatus is connected.
As shown in fig. 4 and 5, in some embodiments of the small airbag pressure monitoring device 10, a flange 223a is disposed on an outer side wall of the connecting head 221a, an avoiding groove 2111 is disposed at an end of the first interface 211, and a clamping protrusion 2112 is disposed on a groove wall of the avoiding groove 2111;
the coupling head 221a may be inserted into the first port 211 to drop the flange 223a into the escape groove 2111 and to fasten the fastening protrusion 2112 to the flange 223 a.
As can be appreciated, the flange 223a is used for mutually clamping with the clamping protrusion 2112, and the groove wall profile of the avoiding groove 2111 and the outer edge profile of the flange 223a are mutually matched, so that the fit clearance between the avoiding groove 2111 and the groove wall of the flange 223a is effectively eliminated, the flange 223a is prevented from being separated from the avoiding groove 2111, and the connection reliability and stability are improved.
It is also understood that the locking protrusion 2112 may include an annular protrusion edge disposed on a groove wall of the avoiding groove 2111 in some embodiments, and may further include a spherical protrusion portion disposed on a groove wall of the avoiding groove 2111, particularly, it is preferable that the connection head 221a is not directly separated from the first interface 211.
As shown in fig. 3 and 4, in some embodiments of the communicating member 21, a supporting member 2113 is disposed in the first port 211, and a connecting check valve 20b is disposed in the connecting head 221a; the propping member 2113 is used for propping the connection check valve 20b open so that the first port 211 communicates with the connection head 221a.
It can be understood that after the first port 211 of the communicating member 21 is assembled with the connecting head 221a, the propping member 2113 will prop the valve core in the connecting check valve 20b to open under the driving of the first port 211, so as to open the first port 211, and after the first port 211 and the connecting head 221a are disassembled, the propping member 2113 will also synchronously withdraw, no longer prop the connecting check valve 20b, and the connecting check valve 20b closes to block the first port 211, so that the pressure of the airbag 20a is maintained.
As shown in fig. 4, the connecting check valve 20b may include a partition 21b having a valve hole 211b, a valve core 22b passing through the through hole 241b, an elastic member 23b sleeved outside the valve core 22b, and a supporting plate 24b having a through hole 241b in some embodiments;
the partition plate 21b and the supporting plate 24b are arranged in the connecting head 221a at intervals, one end of the elastic piece 23b is abutted against the supporting plate 24b, and the other end of the elastic piece 23b is connected with the valve core 22 b;
the valve core 22b can move in a direction away from the supporting plate 24b under the propping of the elastic piece 23b, so that the valve core 22b blocks the valve hole 211b and further blocks the connector 221a; the valve body 22b is also inserted into the through hole 241b by being held by the holding member 2113, thereby opening the valve hole 211b and thus opening the connection head 221a.
It will be appreciated that the diaphragm 21b acts to limit the position of movement of the spool 22 b; the valve hole 211b is used to communicate with both sides of the gas partition plate 21b when opened, and the valve hole 211b is also used to block both sides of the partition plate 21b when closed, that is, to prevent both sides of the partition plate 21b from communicating; the valve core 22b is used for moving towards the direction close to the partition plate 21b under the driving of the elastic piece 23b so as to close the valve hole 211b, and the valve core 22b is also used for moving towards the direction far away from the partition plate 21b against the elastic force of the elastic piece 23b under the jacking of the jacking piece 2113 so as to open the valve hole 211b; the elastic element 23b may be a spring, or may be another element commonly used in the related art that can provide an elastic restoring force; the supporting plate 24b is used for defining the position of the valve core 22b together with the partition plate 21b from two positions respectively, and preventing the valve core 22b from swinging or shifting; the through hole 241b is for providing a moving space for the spool 22 b.
It will be understood that in the case of a certain pressure when the air bag is filled with air, the valve core will be subjected to the force exerted by both the elastic member and the air bag pressure air, so as to ensure that the valve core 22b can still tightly close the valve hole 211b in the case of a certain degree of decrease in the elastic force of the elastic member 23 b.
Further, as shown in fig. 4, in some embodiments of the connection check valve 20b, a blocking member for blocking the valve hole 211b and a limiting member for limiting a moving distance of the valve core may be disposed on the valve core, the blocking member and the limiting member are respectively disposed on two sides of the partition 21b, and the blocking member abuts against the elastic member 23 b.
Understandably, the blocking piece can block the valve hole 211b under the driving of the valve core, and when the propping piece 2113 props the valve core to move, the limiting piece can prevent the valve core from excessively penetrating deeply and being staggered, so that the valve core cannot be correctly reset after the communicating piece 21 is taken down.
As shown in fig. 1 and 2, in some embodiments, the fixing air bag 21a may have an inverted cone shape with a narrow lower part and a wide upper part.
Understandably, the shape of the lower part is narrow and the upper part is wide, so that the fixing air bag 21a can be more fit with the trachea of a patient, the fixing air bag 21a is better fixed in the trachea of the patient, and the stability of the fixed trachea cannula is improved.
