The actuator of driven by hand switch above Anesthesia machine is to drive driven by hand switch will be numb for anesthesia machines person
The vent path of liquor-saturated machine switches between two states of manual ventilation and motor-driven ventilation.
In one embodiment of the invention, with reference to Fig. 1 and in conjunction with Fig. 2, the actuator of driven by hand switch may include:
Handlebar 101, central axis 102, shaft 103, roller bearing 201 and pedestal 106.Wherein, handlebar 101 can be rotated with around the shaft 103,
Shaft 103 can be located on pedestal 106.One end of central axis 102 can be connected with the diaphragm 202 in driven by hand switch,
The other end of central axis 102 can be connect with one end of roller bearing 201, it may be assumed that one end of roller bearing 201 can be fixedly through central axis
102 other end.In one embodiment of the invention, one end of roller bearing 201 can be along the axial direction side perpendicular to central axis 102
To the other end for being fixed on central axis 102.
With reference to Fig. 2 and Fig. 5 is combined, guide groove 501 can be offered on handlebar 101, the other end of roller bearing 201 can be located at
In guide groove 501.Guide groove 501 can be used for guiding the motion profile of roller bearing 201.In one embodiment of the invention, roller bearing 201
Can be set idler wheel 203 on that one end being in contact with guide groove 501, the periphery of idler wheel 203 can be in contact with guide groove 501 and
It can be rotated around roller bearing 201.In one embodiment of the invention, the shape of guide groove 501 can be the shaped form of closure, work as behaviour
When stirring handlebar 101 as member makes its 103 rotation around the shaft, the shape of the curve of the closure determines the movement rail of roller bearing 201
Mark.In one embodiment of the invention, the shape of guide groove 501 can be the shape of similar letter S.
With reference to Fig. 3 and Fig. 5 is combined, by the shape for designing suitable closed curve, so that it may so that handlebar 101 rotates
The rotation of axis 103 is converted into the reciprocating motion that roller bearing 201 drives central axis 102 along the axial direction of central axis 102, thus band
Dynamic diaphragm 202 moves between manual ventilation access and motor-driven vent path to block one of vent path, to realize hand
Switching between dynamic state and maneuvering condition.Specifically, when roller bearing 201 is located at one end of guide groove 501, can make manually
Automotive is switched to a state, when roller bearing 201 is located at the other end of guide groove 501, driven by hand switch can be made to cut
Change to another state.
In order to provide the clearly sound to operator during stirring handlebar 101, and ensure that driven by hand switchs
It is reliably switched to one of state, in one embodiment of the invention, spring can also be set in actuator
Part.With reference to Fig. 1, one end of spring part 105 can be in contact with handlebar 101, and the other end can be with 106 phase of pedestal of actuator
Contact.
With reference to Fig. 6 and combine Fig. 7 that taper hole 701, phase can be set on pedestal 106 in one embodiment of the invention
Ying Di, can be set piston bush 601 on the one end of spring part 105 being in contact with pedestal 106, and spring part 105 can lead to
The piston bush 601 crossed thereon is in contact with taper hole 701.
With reference to Fig. 4 and Fig. 6 is combined, it in one embodiment of the invention, can be in handlebar 101 and spring part 105
Two position-limited claws 401 and 402 are arranged in the one end being in contact correspondingly being in contact with handlebar 101 in spring part 105
One end on roller 602 and drum shaft 603, the interconnecting piece 403 of the periphery of roller 602 and two position-limited claws 401 and 402 are set
It is in contact, roller 602 can be rotated around drum shaft 603.The both ends of drum shaft 603 are respectively and in two position-limited claws 401 and 402
While being in contact.In this way, the inner edge of position-limited claw with the both ends of drum shaft 603 and being in contact when handlebar 101 swings back and forth
Limit the slewing area of handlebar 101.That is: when handlebar 101 turns to the inner edge of drum shaft 603 and position-limited claw 401 and 402
When the position that one end is in contact, handlebar 101 will be unable to continue to rotate.In addition, when drum shaft 603 touches 401 He of position-limited claw
When one end of 402 inner edge, due to the collision of the two, clearly sound will be issued.In one embodiment of the invention, it rolls
The part that cylinder 602 is in contact with drum shaft 603 is also provided with axle sleeve 604.
In one embodiment of the invention, with reference to Fig. 5 and in conjunction with Fig. 6, flanging 502 has been can be set in the both ends of guide groove,
When roller bearing 201 moves to the both ends of guide groove, under the tension force effect of the spring 605 in spring part 105, roller bearing 201 is compacted
In on flanging 502.In this manner it is possible to make handlebar 101 steadily by driven by hand switch keeping in manual mode or motor-driven
State.
So far the actuator that the driven by hand according to an embodiment of the present invention for Anesthesia machine switchs is described.According to this hair
Bright actuator can provide symmetry equivalent torque to operator when manually-maneuvering condition switches, and prevent spring raw
Rust, is easily installed maintenance.
The above description is only an embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should be included within scope of the presently claimed invention.
