The actuator of the driven by hand switch above Anesthesia machine drives driven by hand switch the vent path of Anesthesia machine to be switched between manual ventilation and motor-driven ventilation two states for anesthesia machines person.
In one embodiment of the invention, with reference to figure 1 also composition graphs 2, the actuator of driven by hand switch can comprise: handlebar 101, central shaft 102, rotating shaft 103, roller bearing 201 and base 106.Wherein, handlebar 101 can 103 rotate around the shaft, and rotating shaft 103 can be positioned on base 106.One end of central shaft 102 can be connected with the barrier film 202 in driven by hand switch, and the other end of central shaft 102 can be connected with one end of roller bearing 201, that is: one end of roller bearing 201 can be fixedly through the other end of central shaft 102.In one embodiment of the invention, the other end of central shaft 102 can be fixed in one end of roller bearing 201 along the axial direction perpendicular to central shaft 102.
With reference to figure 2 also composition graphs 5, handlebar 101 can offer guide groove 501, and the other end of roller bearing 201 can be positioned at guide groove 501.Guide groove 501 may be used for the movement locus guiding roller bearing 201.In one embodiment of the invention, that one end that roller bearing 201 contacts with guide groove 501 can be provided with roller 203, the periphery of roller 203 can contact with guide groove 501 and can rotate around roller bearing 201.In one embodiment of the invention, the shape of guide groove 501 can for closed shaped form, when operator stir handlebar 101 make its around the shaft 103 rotate time, the shape of this closed curve determines the movement locus of roller bearing 201.In one embodiment of the invention, the shape of guide groove 501 can be the shape of similar alphabetical S.
With reference to figure 3 also composition graphs 5, by designing the shape of suitable closed curve, just can make handlebar 101 around the shaft 103 rotation be converted into the reciprocating motion of roller bearing 201 with the central shaft 102 centrally axial direction of axle 102, thus drive barrier film 202 mobile to block one of them vent path between manual ventilation path and motor-driven vent path, to realize the switching between manual mode and maneuvering condition.Specifically, when roller bearing 201 is positioned at one end of guide groove 501, driven by hand switching over can be made to a state, when roller bearing 201 is positioned at the other end of guide groove 501, driven by hand switching over can be made to another state.
In order to provide the sound clearly to operator in the process of stirring handlebar 101, and guaranteeing that driven by hand switch is reliably switched to one of them state, in one embodiment of the invention, spring part can also be set in actuator.With reference to figure 1, one end of spring part 105 can contact with handlebar 101, and the other end can contact with the base 106 of actuator.
With reference to figure 6 also composition graphs 7, in one embodiment of the invention, taper hole 701 can be set on base 106, correspondingly, one end contacted with base 106 of spring part 105 can be provided with piston bush 601, and spring part 105 can be contacted with taper hole 701 by the piston bush 601 on it.
With reference to figure 4 also composition graphs 6, in one embodiment of the invention, two position-limited claws 401 and 402 can be set in one end contacted with spring part 105 of handlebar 101, correspondingly, cylinder 602 and drum shaft 603 can be set on one end contacted with handlebar 101 of spring part 105, the periphery of cylinder 602 contacts with the connecting portion 403 of two position-limited claws 401 and 402, and cylinder 602 can rotate around drum shaft 603.The two ends of drum shaft 603 contact with the inner edge of two position-limited claws 401 and 402 respectively.Like this, when handlebar 101 swings back and forth, the inner edge of position-limited claw limits the slewing area of handlebar 101 by contacting with the two ends of drum shaft 603.That is: when handlebar 101 turns to the position that drum shaft 603 contacts with one end of the inner edge of position-limited claw 401 and 402, handlebar 101 cannot be rotated further.In addition, when drum shaft 603 touches one end of the inner edge of position-limited claw 401 and 402, due to both collisions, sound clearly will be sent.In one embodiment of the invention, the part that cylinder 602 contacts with drum shaft 603 can also be provided with axle sleeve 604.
In one embodiment of the invention, with reference to figure 5 also composition graphs 6, the two ends of guide groove can be provided with flanging 502, and when roller bearing 201 moves to the two ends of guide groove, under the tension force effect of the spring 605 in spring part 105, roller bearing 201 is pressed on flanging 502.Like this, just can make handlebar 101 stably by driven by hand switch keeping in manual mode or maneuvering condition.
To the actuator of the driven by hand switch for Anesthesia machine that described herein according to the embodiment of the present invention.According to actuator of the present invention, symmetry equivalent moment can be provided when manually-maneuvering condition switches to operator, and prevent spring from getting rusty, be easy to installation and maintenance.
The foregoing is only embodiments of the invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
