Abstract
The utility model relates to a portable emergency breath machine, which belongs to the medical equipment. The portable emergency breath machine is mainly composed of an air bag and the compressing mechanism of the air bag; the compressing mechanism of the air bag is composed of a speed reducer driven by a motor, an incomplete gear and a rack bar; the incomplete gear can be driven to rotate by rotating the motor; air can be sent to patients by pushing the rack bar and compressed the air bag; when the part with teeth of incomplete gear disengages from the rack bar, the rack bar can reset with the air bag under the action of a restoring spring, and the air supply of intermittence can be realized; the air bag is also provided with a vent with an adjusting valve which can be used for adjusting tidal volume. The utility model has the advantages of small volume and light weight, which can be used for field first aid and can be arranged on the stretcher or the barrow of patients transportation.
Description
This utility model belongs to armarium, is a kind of respirator that supplies first aid to use.
At present both at home and abroad institute's its complex structure of respirator that uses, volume are big, are not easy to random mobile.But in many occasions, deliver in the road of hospital, all need to implement controlled breathing to patient as field first aid or with the patient of respiratory failure or respiratory arrest.And existing respirator carries and moves because of inconvenience, thus be difficult in emergency circumstances use above-mentioned, to such an extent as to cause the method that still adopts hands to pinch air bag at present to come patient is implemented the situation of controlled breathing.Pinch air bag with hands and patient is implemented controlled breathing not only require medical personnel that certain experience will be arranged, and physical demands is also very big.Chinese patent CN90224512 discloses a kind of anesthesia respirator, and this respirator has adopted the pneumatic logic control method, though saved power supply, requires to possess the source of the gas that certain pressure is arranged.Not only price is more expensive economically for this, and is difficult to realize in many occasions and remoter place.In addition, commercially available respirator costs an arm and a leg because of it at present, makes many medical institutions be difficult to popularize.
The purpose of this utility model provides a kind of simple in structure, cheap, and portable portable first-aid respirator.
Realize that solution of the present utility model is: the portable first-aid respirator that is provided comprise one bring into, the gentle bag pressure of air bag of air vent contracts mechanism.The reducing gear that this air bag compressing mechanism is driven by direct current generator, the imperfect gear that is connected with this mechanism and form with the tooth bar of imperfect gears engaged, an end of its middle rack links to each other with the free end of air bag.The inner chamber of air bag is provided with back-moving spring, also is provided with the drain of a band flow control valve on the air bag.Starter motor during use, imperfect gear rotates, and drives tooth bar and move, and makes the air bag compression, gives patient with air in the air bag.After imperfect gear rotation was crossed certain angle, it had toothed portion promptly to break away from tooth bar, air bag distending under action of reset spring then, and air admission air bag, tooth bar also turn back to the home position.When imperfect gear have toothed portion to mesh with tooth bar once more the time, drive tooth bar again and move, the compressing gasbag aerofluxus and so forth, realizes that batch (-type) supplies gas.
Because the ratio that toothed portion and no toothed portion are arranged of imperfect gear is 1: 2, thereby the pass that makes the inspiratory/expiratory of each controlled breathing maintain 1: 2 fastens, so that make the absorption of oxygen and the discharge of carbon dioxide keep comparatively ideal state.
The breathing rate of this respirator is to advance enforcement by the rotating speed of regulating direct current generator.Tidal volume can be regulated by the aperture of regulating above-mentioned said air bag drain.When compressing gasbag, portion of air (being required tidal volume part) is given patient through air vent, and another part part of tidal volume (promptly greater than) enters atmosphere by drain.Therefore, as long as the size of regulating drain by flow control valve, i.e. the each gas pushing quantity of scalable, this structure has also been avoided the excessive damage that causes to lung and air flue of because of gas pushing quantity excessive and aspirated pressure.
This respirator volume is little, and is in light weight, simple in structure, easy to carry, and its power supply is an AC/DC, and under the situation of no any power source, also can manually breathe.Therefore can be widely used in field first aid, and can be placed on the stretcher or go-cart that transports patient, so that implement controlled breathing in the way.Because its cost is lower, institute is so that promote the use of in vast medical institutions.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Accompanying drawing is a structure diagram of the present utility model.
As shown in the figure: the air bag 2 of the corrugated tube shape that is being connected on the top of housing 1, this air bag has three mouths: air vent 3, air inlet 4 and drain 5.Air vent 3 places are provided with check valve 6 and four-way union 7, wherein one tunnel 8 logical Pressure gauge; The two 9 the tunnel lead to patient; Third Road 10 communicates with source of oxygen, and air inlet 4 places also are provided with check valve 11.Drain 5 communicates with flow control valve 13 by flexible pipe 12.Be provided with back-moving spring 14 in the air bag.Direct current generator 15 is located at the bottom of housing, and its axle is connecting worm screw 17.The imperfect gear 18 that is being connected on the axle of worm gear 16 is meshed with tooth bar 20 by idler gear 19, and an end of tooth bar 20 is connected with the free end of air bag.When motor 15 rotates, drive imperfect gear 18 by worm and wormwheel and rotate.Imperfect gear 18 19 engagements of toothed portion and idler gear are arranged the time, promptly promote tooth bar 20 and move ahead, compressing gasbag 2 is given patient's air feed; Imperfect gear have toothed portion to break away from idler gear 19 after, the center tooth wheel and rack all is in free state, under the effect of air bag back-moving spring 14, air bag 2 distendings, air inlet, and order about tooth bar 20 and reset.The effect of control valve 13 is high-volume what of control air bag its inner chamber air of when compression, thereby may command is given patient's gas pushing quantity.Direct current generator in this example adopts decompression speed, in order to satisfy the requirement of different breathing rates, motor power can adopt accumulator 21 power supplies, also can connect by transformator 25 and alternating current, when if preceding two kinds of power supplys all do not have, can operate hand lever 22 and move ahead by the summits 23 that fulcrum 24 promotions 24 promote to be connected with tooth bar 20, compressing gasbag is supplied gas.
