The invention further provides the anesthesia apparatus with the interlocking device. Through the technical scheme provided by the invention, the two evaporating pots of the anesthesia apparatus can be vertically assembly up and down and the visual angles of the evaporating pots are relatively good.
Description
Technical field
The present invention relates to the Medical Equipment technical field, particularly a kind of two equipment that evaporator is opened simultaneously that prevent anesthetic machine.
Background technology
Evaporator is a critical component of anesthetic machine, and existing a lot of anesthetic machines can be equipped with two evaporators, and these two evaporators in use must assurance can not be in open mode simultaneously.The interlock of evaporator is used for exactly guaranteeing that another evaporator can't be opened when an evaporator is in open mode that this also is the requirement of 54.101 chapters and sections among the rules IEC60601-2-13.
Existing interlock all adopts horizontal push rod interlocking side by side on the market.Its operation principle is that when any one evaporator was opened use, the push rod that the rotation of circular scale can drive its both sides ejected.During the work of first evaporator, its push rod closely touch the push rod of second evaporator, has guaranteed that the push rod of second evaporator can not eject simultaneously like this, has also just guaranteed the use that can not be opened simultaneously of second evaporator.Based on this operation principle, the rigging position of two evaporators is restricted to can only horizontal position adjacent.It is the inner side that occupy machine that an evaporator like this, is always arranged.Because evaporator has bigger deadweight usually, certain distance is arranged at interval when getting again if hang, it is bad to add upward angle of visibility, does not meet ergonomics.
In addition in some cases, two evaporators of horizontal Tile, very unfavorable to control and the adjusting of complete machine self center of gravity.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new evaporator interlock, can only the level assembling to solve in the prior art evaporator, the evaporator visual angle is bad, be unfavorable for the control of anesthetic machine self center of gravity and the problem of adjusting.
In order to address this problem, a first aspect of the present invention is to provide a kind of evaporator interlock, comprise first push rod, second push rod, rotating shaft, shaft seat, motion bar and fixing head, one end of first push rod is connected with first evaporator and opening or closing and move reciprocatingly in the horizontal direction with first evaporator, one end of second push rod is connected with second evaporator and opening or closing and move reciprocatingly in the horizontal direction with second evaporator, it is characterized in that: the vertical connection of an end of the first push rod other end and motion bar, the other end of second push rod is connected with the other end of motion bar is vertical, described rotating shaft is installed on the shaft seat, shaft seat is installed on the fixing head perpendicular to horizontal plane, and motion bar rotates around the axis.
For addressing this problem, combine with above-mentioned first aspect, a second aspect of the present invention is to provide a kind of evaporator interlock, and the two ends of described motion bar are respectively arranged with and can make motion bar at two evaporators back-moving springs vertical with horizontal plane under the closing state all.
For addressing this problem, combine with above-mentioned second aspect, a third aspect of the present invention is to provide a kind of evaporator interlock, and an end of described each root back-moving spring is connected with described fixing head, and the other end is connected with motion bar.
For addressing this problem, the present invention also provides a kind of anesthetic machine, comprises the described evaporator interlock in top three aspects.
Compared with prior art, a kind of evaporator interlock provided by the invention and comprise the anesthetic machine of this device, its beneficial technical effects is:
1, two evaporators can vertically assemble up and down, make that the visual angle of evaporator is better;
2, be conducive to control and adjusting to anesthetic machine complete machine self center of gravity.
Description of drawings
Fig. 1 is the structural representation of a kind of evaporator interlock of proposing of the present invention;
Fig. 2 is the structural representation of a kind of evaporator interlock in the specific embodiment of the invention;
Fig. 3 is the sketch map of the anesthetic machine of a kind of evaporator interlock that comprised that the present invention proposes.
Identical number designation is represented same assembly in institute's drawings attached.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 has shown the overall construction drawing of a kind of evaporator interlock that the present invention proposes.First evaporator 1 and the vertical installation up and down of second evaporator 2, one end of first push rod 3 connects with first evaporator and is parallel with horizontal plane, the vertical connection of one end of the other end of first push rod 3 and motion bar 5, one end of second push rod 4 connects with second evaporator 2 and is parallel with horizontal plane, the vertical connection of the other end of the other end of second push rod 4 and motion bar 5, rotating shaft 7 is installed on the shaft seat 6 and with shaft seat 6 is fixed on the fixing head 8 perpendicular to horizontal plane in the lump, motion bar 5 centre position is along its length passed in rotating shaft 7, make that motion bar 5 can be support with shaft seat 6, around the shaft 7 rotations of doing the lever motion formula.
In addition, as shown in Figure 2, this evaporator interlock also comprises back-moving spring 9 and 10, and an end of back-moving spring 9 is connected with fixing head 8, and the other end is connected with an end of motion bar 5; One end of back-moving spring 10 is connected with fixing head 8, and the other end is connected with the other end of motion bar 5.
In the process that reality is used, when two evaporators all are in closed condition, owing to the elastic force effect of two back-moving springs 9 and 10, can make motion bar 5 keep vertical.When evaporator 1 was opened, first push rod 3 outwards ejected along continuous straight runs, because vertical connection of an end of first push rod 3 and motion bar 5, this will make that motion bar 5 is support with shaft seat 6,7 does lever motion around the shaft.Owing to the other end vertical be connected of second push rod 4 with motion bar 5, under the drive of motion bar 5, second push rod 4 also can inwardly move by along continuous straight runs, and like this, evaporator 2 can't be opened.Equally, if opened evaporator 2 earlier, also will cause evaporator 1 to open, this has just reached the purpose of two evaporator interlockings.
Fig. 3 is the sketch map that has comprised the anesthetic machine of above-mentioned evaporator interlock, as can be seen from this figure, has adopted two evaporators of the anesthetic machine of new interlock can realize top-bottom layout, and two evaporators can be installed in the outer surface of machine.With respect to existing anesthetic machine, new anesthetic machine has significantly promoted the availability of equipment, makes user's use impression better, and has simplified regular job and maintenance, has reduced the risk that evaporator falls, and has ensured the safety of operation.
