A kind of artificial ventilator of scalable air inflow
Technical field
The present invention relates to a kind of artificial ventilator of scalable air inflow, specifically limit the air inflow of artificial ventilator automatically, thereby can be patient's gas transmission safely and efficiently, the invention belongs to technical field of medical instruments according to the vital capacity of first-aid patients.
Background technology
Economic development rapid growth in current society, the paces of people's work and life are also accelerated thereupon, and many people anoxybiotic situation occurs through regular meeting under the operating pressure of high load capacity, and some heart patients are especially serious.Many patients need to practice artificial respiration under many situations, but everyone vital capacity difference, required oxygen is also different, if medical personnel too much can cause patient's potential safety hazard for patient's displacement in giving the process of first-aid patients gas transmission, and the pulmonary spalling that cause etc. excessive as pulmonary's amount of bearing, and displacement can not be realized the purpose of first aid when not enough, and when coming curing patient with traditional mode, people except that medical personnel pushes the amount size of discharging gas when spheroid is revived in first aid to patient and is difficult to determine, be difficult to accurately hold the size of the displacement of giving patient, make that rescue is difficult to implement.At this moment just need a kind ofly can regulate the artificial ventilator of air inflow especially, thereby can alleviate medical personnel's burden, strengthen the safeguard protection of first-aid patients, but this artificial ventilator occur as yet on market according to patient's vital capacity.
Summary of the invention
At above-mentioned deficiency, the invention provides and a kind ofly can regulate the artificial ventilator of air inflow automatically, the salvor need not operation skill when operation, only need measure the vital capacity of first-aid patients, adjust artificial ventilator then in advance, artificial ventilator is the scalable air inflow, and indication the salvor give first aid to.
The present invention is achieved by the following technical solutions:
A kind of artificial ventilator of scalable air inflow, it comprises face shield, connecting device, the first aid spheroid of reviving, gas storage relief valve, gas-storing bag, it is characterized in that, the described first aid spherical register of the elastic internal layer of spheroid built-in of reviving, the spherical register of described internal layer are positioned at the first aid outer part of spheroid of reviving and are provided with gas blow pipe by pressure regulator valve control, are provided with the uniaxial pressure relief valve on connecting device between spheroid and the face shield is revived in first aid.
The invention has the beneficial effects as follows, the inflatable venting of the spherical register of described internal layer, before gas transmission, in the spherical register of internal layer, inflate by gas blow pipe, the spherical register of internal layer expands according to the volume of importing gas flow thereupon and keeps shape invariance, after whole artificial respiration's process finishes the gas in the spherical register of internal layer is emitted.Thereby medical personnel can grasp displacement to patient substantially exactly by touching the spherical register of internal layer in the extruding gasbag process, for patient's safety provides good guarantee.
Description of drawings
Fig. 1 is for can regulate the artificial ventilator 3 dimensional drawing of air inflow automatically;
Among the figure: 1, face shield, 2, connecting device, 3, the first aid spheroid of reviving, 4, the spherical register of internal layer, 5, the gas storage relief valve, 6, gas-storing bag, 7, the uniaxial pressure relief valve, 8, pressure regulator valve, 9, gas blow pipe.
The specific embodiment
As Fig. 1, the artificial ventilator of this kind scalable air inflow, it comprises face shield 1, connecting device 2, the first aid spheroid 3 of reviving, gas storage relief valve 5, the gas-storing bag 6. first aids spherical register 4 of spheroid built-in one elastic internal layer of reviving, the spherical register of described internal layer is positioned at the first aid outer part of spheroid of reviving and is provided with gas blow pipe 9 by pressure regulator valve 8 controls, is provided with uniaxial pressure relief valve 7 on connecting device between spheroid and the face shield is revived in first aid.
During use, close the first aid gas storage relief valve 5 of spheroid 3 and gas-storing bag 6 junctions of reviving, and in gas-storing bag 6, inject capacity gas.Measure patient's vital capacity in advance, determine patient's requisite oxygen tolerance, and this quantitative gas filled in the spherical register 4 of internal layer by gas blow pipe 9, charge in the spherical register 4 of internal layer and begin to expand behind a certain amount of gas and its volume and gas flow are the linear changing relation, pressure regulator valve 8 on it can be regulated the air pressure in the spherical register 4 of internal layer automatically, and the spherical register 4 of internal layer was kept shape invariance after inflation finished.Face shield 1 is fixed on patient's face.Open gas storage relief valve 5, with the hands extruding first aid spheroid 3 of reviving, in extrusion process, run into the spherical register 4 of internal layer and just stop extruding, unclamp hands, push the first aid spheroid 3 of reviving again, stop extruding after touching the spherical register 4 of internal layer, carry out so repeatedly, gas flows in the patient body by connecting device 2, thereby is patient's gas transmission.Be in patient's gas transmission process, revive spheroid 3 of first aid can be opened or close according to gas flow automatically with the uniaxial pressure relief valve 7 of the contact position of face shield 1, that is: when pushing first aid, the rescue personnel revives spheroid 3 during for patient's gas transmission, one-way relief valves 7 was opened when gas was revived in the spheroid 3 inflow patient bodies from first aid, and stopped by unidirectional relief valve 7 that when the gas reverse flow making it can not reverse flow.
After finishing using, close gas storage relief valve 5, and the gas in the spherical register 4 of internal layer is emitted, finish the whole process into patient's gas transmission, safety is efficient again.
