The purpose of this utility model is that a kind of improved external cardiac massage and artificial respiration training devices will be provided, it not only can save mechanical component such as pneumatic device, large-sized lever and slide bar and make device obtain simplifying, and can also make the replacement of lung bag become very convenient.
This utility model is to constitute like this, it is a kind of external cardiac massage and artificial respiration training devices, shifter and artificial respiration training institution by cardiac massage position mechanism for identifying, vertical displacement signal form, and it is characterized in that the shifter of cardiac massage position mechanism for identifying and vertical displacement signal is arranged in the coaxial device by a slide block.
Device of the present utility model makes the shifter of cardiac massage position mechanism for identifying and vertical displacement signal the whole series to be installed in spring and the plastic tube by this coaxial design, thereby solved the contradiction that various members occupy the anthropometric dummy inner space, make device obtain simplifying greatly, and needn't remove other parts again when changing the lung bag, very convenient.
Concrete structure of the present utility model can be provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to external cardiac massage that the utility model proposes and artificial respiration training devices's profile.
Sketch map when Fig. 2 is the cardiac massage malposition of said apparatus.
Sketch map when Fig. 3 is the cardiac massage correct position of said apparatus.
Fig. 4 is the work sketch map of said apparatus artificial respiration training institution.
Come this utility model is done further detailed description below in conjunction with accompanying drawing.
With reference to Fig. 1, this external cardiac massage and artificial respiration training devices are made up of 18 parts shown in Figure 1.Wherein, cardiac massage position mechanism for identifying is by external massage operation key (1), and little spring (3), link rod (5), contact key (7) and inching conversion switch (8) are formed.Require operator's the vertical compressing position must be at breast xiphoid-process two finger places upwards during external cardiac massage, the mechanism for identifying of this cardiac massage position be by this requirement design.When operator's hands definitely is pressed in this tram, external massage operation key (1) just is forced into supporting plate (2) flat, promote contact key (7) by link rod (5) and be contained in the inching conversion switch (8) on slide block (9) top to lower compression, thus make original normally closed contact A commutate to normal opened contact B(as shown in Figure 3).Can obtain to represent to massage correct signal when continuing to be pressed onto 4～5 centimeters vertically downward.If operator's massage malposition so just must be oppressed less than external massage operation key (1), even exert oneself, microswitch (8) also is in the position (as shown in Figure 2) of normally closed contact A again, thereby can not obtain representing to massage correct signal.As when continuing vertically firmly to be pressed downwardly onto 4～5 centimeters, instrument will demonstrate the incorrect signal of massage.
The shifter of vertical displacement signal is by supporting plate (2), and interior pipe (6), slide block (9), compression spring (4), outer tube (11) and conductive seat (13) are formed.During external cardiac massage, should sink 4～5 centimeters behind patient's thorax pressurized, this mechanism is according to this requirement design, if it is firmly not enough, the signal display area of this device does not just have any indication, if it is firmly appropriate, then supporting plate (2) is just stressed downward, promoting slide block (9) by interior pipe (6) glides, when sliding into 4～5 centimeters instantly, the lower metal of slide block (9) part just contacts with conductive seat (13), introduces power supply by lead C, again through slide block (9) and microswitch (8) connection and formation output, massage correct signal at last thereby obtained expression.
In this device, obtain representing to massage correct signal, the vertical displacement amount is appropriate in the time of must accomplishing to massage the correct and massage of position simultaneously, and both are indispensable.Iff correct position and not enough that of displacement just can not get any signal, the malposition if displacement is enough, that will obtain the incorrect signal of expression massage.
Slide block (9) seems very important in this device, it makes that the shifter of cardiac massage position mechanism for identifying and vertical displacement signal reasonably is arranged in the coaxial device, and the correctness that the cardiac massage position is differentiated and the conversion of vertical displacement signal all will realize by it.In fact it is dimeric, and top is plastics car systems, and the lower part is a metal, and this metal part links to each other with the central contact D of inching conversion switch (8).
No matter to be its pipe internal surface or tube outer surface contact with nearly all slide unit interior pipe (6) in this device, therefore selects for use fluorine-containing engineering material to make, and can make it and the friction between each slide unit reduce to the degree of minimum like this.
It highly is 160 millimeters compression spring (4), external diameter is 54 millimeters, and the steel wire of coiling spring is 5.5 millimeters, altogether 10 joints, its deflection is 10 kilograms/centimeter, but also can be according to the diameter of different situation (as sex, age etc.) change height, external diameter and spring steel wire.
During the artificial respiration, the gas that requires the operator once to be blown into the patient reaches 800 milliliters, the artificial respiration training institution of this device is according to this requirement design, its structure as shown in Figure 1, it is mainly by lung bag (16) on anthropometric dummy back (17) and artificial lung supporting plate (15) formation.When gas is blown into, lung bag (16) thus with regard to inflation artificial lung supporting plate (15) is held up, the height of artificial lung supporting plate (15) makes reverse lever (18) be horizontal just when the inflation of lung bag reaches 800 milliliters, thereby make the d-e conducting (as shown in Figure 4) of artificial respiration's microswitch (12), can obtain the signal of representing that air-blowing quantity is correct at last.Artificial respiration's microswitch (12) produces action by reverse lever (18), here, reverse lever (18) is to rotate in 120 ° scope, a kind of like this slewing area is except the d-e conducting that can make artificial respiration's microswitch (12), can also make the taking-up of lung supporting plate (15) and lung bag become very convenient, change the trouble that to remove lever before the lung bag in the existing apparatus thereby overcome.
