Description
Technical field
The present invention relates to anesthetic machine technical field, relate in particular to a kind of anesthesia evaporator locking device, and utilize this anesthesia evaporator locking device that anesthesia evaporator is locked to the method on anesthetic machine.
Background technology
Anesthesia evaporator (vaporizer) is the special purpose device of controlling the output of volatile anesthetic thing steam.Basic function is gasification volatile anesthetic, controls the concentration of anesthetic vapor in live gas.Anesthesia evaporator is a kind of device that can effectively evaporate anesthetic liquid medicine and can accurately anesthetics be inputted to breathing circuit for anesthesia by finite concentration.Desirable vaporizer requires simple to operate, and output concentration is accurate, is subject to the factors such as temperature, flow, pressure to affect little.Vaporizer is the critical component of anesthetic machine.Due to potent inhalational anesthetic use, the quality of its quality not only indicates the level of anesthetic machine, also relates to patient's safety.So while using anesthetic machine, must conscientiously check vaporizer, tackle if desired its output concentration and monitored.
In order to ensure the normal work of anesthesia evaporator, in working order time, must utilize anesthesia evaporator locking device that anesthesia evaporator is locked on anesthetic machine.But existing anesthesia evaporator locking device has following two defects:
1, at present the anesthesia evaporator of part does not have action sequence, easily occurs being also articulated on anesthetic machine of safety of anesthesia evaporator, the vaporizer work that is just unlocked.As shown in Figure 1, the switching device of this anesthesia evaporator comprises graduated disc 10, be fixedly installed cam 11 at the downside of graduated disc 10, and cam 11 is coaxial rotation with graduated disc 10, cam 11 peripheries arrange helical groove, in helical groove, coupling arranges pulley 12, one side of pulley 12 arranges pushing depression bar 13, and pulley 12 can freely rotate along the axle center of pushing depression bar 13, pushing depression bar 13 is fixedly connected with push pedal 15 away from one end of pulley 12, push pedal 15 two ends are all fixedly connected with anesthesia evaporator by stop screw, on stop screw, be provided for the spring that push pedal 15 is resetted, push pedal 15 centers are run through setting and are tightened axle 14, push pedal 15 downsides are provided for the bypass valve 16 being communicated with anesthesia evaporator.In the time that needs are opened anesthesia evaporator, be rotated counterclockwise graduated disc 10, graduated disc 10 is with moving cam 11 to be also rotated counterclockwise, cam 11 contacts with the pulley 12 that pushing depression bar 13 one end arrange, pulley 12 rises on the inclined-plane of the helical groove on cam 11, push depression bar 13 and be also propradation near one end of pulley 12, utilize lever principle, pushing depression bar 13 is decline state away from one end of pulley 12, pushing push pedal 15 moves downward, anesthesia evaporator is communicated with bypass valve 16, and is locked with bypass valve 16 by tightening axle 14 rotations; In the time that needs are closed anesthesia evaporator, reverse rotation graduated disc 10, unclamps simultaneously and tightens axle 14, can make anesthesia evaporator separate with bypass valve 16.The switching device of this anesthesia evaporator does not have timing, while anesthesia evaporator not being fixed on to the bypass valve 16 on anesthetic machine in the lower end that tightens axle 14, graduated disc 10 still can rotate, and cam also can drive pushing depression bar 13 to exert pressure to push pedal 15, anesthesia evaporator is communicated with bypass valve 16, now anesthetic gases can leak from anesthesia evaporator and bypass valve contact surface, cause the pollution to environment and the injury to human body, it is corresponding in the situation that anesthesia evaporator graduated disc 10 is not closed, tightening axle 14 can rotate and make the bypass valve of vaporizer from anesthetic machine to depart from, cause the anesthetic gases in vaporizer to flow out, also can damage to environment with to human body.
Although 2, also have part anesthesia evaporator to have certain timing, the locking device in this anesthesia evaporator is without depressing, and directly screws to realize to articulate, this to articulate mode reliability poor, and security performance is low.(part-structure please refer to shown in Fig. 1) as shown in Figure 2, this anesthesia evaporator locking device comprises graduated disc 10, bypass valve 16, with the fixing cam 11 of graduated disc 10, the push pedal 15 being communicated with bypass valve 16 by the rotation pushing of cam 11, and lock by rotation and bypass valve 16 tighten axle 14, the described axle 14 that tightens is provided with bearing pin 141 near described push pedal 15 bottom surface places, described push pedal 15 bottom surfaces are provided with described bearing pin 141 and coincide, and can hold the groove 151 of described bearing pin 141, and the angle between described bearing pin 141 and described groove 151, with tighten the angle that need to rotate when axle 14 and bypass valve 16 are locked and equate.Although the locking device in this anesthesia evaporator can start when the duty not by the engagement limits anesthesia evaporator of bearing pin 141 and groove 151, but this locking device still has following defect in the time of locking: the move distance of push pedal 15 is relatively long, or the thickness of push pedal 15 is thicker therefore, the degree of depth of the groove 151 that its bottom arranges can meet the motion of push pedal 15, so not only temporary larger space, also make material cost increase; The groove 151 arranging in push pedal 15 is groove, groove if, in the time of normal work, bearing pin 141 may move to beyond push pedal 15 upper surfaces so, so at this moment tightens axle 14 and is rotated, can make to separate between anesthesia evaporator and anesthetic machine, now leaking easily appears in anesthesia evaporator.
