The utility model is characterized in that an oxygen input mouth which is connected with an oxygen source is connected with a safety pressure regulating valve, a peak inspiratory pressure regulating valve and an end expiration positive pressure regulating valve orderly through pipelines, each of the pipelines is composed of an airway pipe and a three-way pipe which are connected with each other, and a barometer is arranged between the pipelines of the safety pressure regulating valve and the peak inspiratory pressure regulating valve.

Description

Adjustable pressure respiratory device

This utility model relates to a kind of adjustable-pressure resuscitator, belongs to technical field of medical instruments.

At present, the aspirated pressure of automatic inflation recovery capsule that hospital uses or anesthesia air bag is to be controlled by the size that the operator pushes the inflating balloon dynamics, no pressure shows, can not set up accurate constant aspirated pressure, and can not set up end expiratory positive pressure, in addition, automatically the supply of inflation recovery air bag is to be interrupted air-flow, is unfavorable for the rapid discharge of expired gas, and the part expired gas can repeat to suck, can not meet clinical needs, influence the further raising of therapeutic effect.Using the ventilation of recovery air bag not only needs skilled operation skill, if the operating time is longer, physical demands is bigger, also is easy to fatigue.

The purpose of this utility model is to provide a kind of and has continuous flow and pressure demonstration, and can set up the resuscitator of safe pressure, Peak Inspiratory Pressure and end expiratory positive pressure as required.

The purpose of this utility model is achieved in that the oxygen feeder that is connected with oxygen source passes through pipeline and presses control valve with safety in turn, and Peak Inspiratory Pressure control valve and end expiratory positive pressure control valve link to each other; This pipeline is to be formed by connecting by airway and tee T, is provided with air gauge between the pipeline of safety pressure control valve and Peak Inspiratory Pressure control valve.

The utlity model has following advantage:

(1) Peak Inspiratory Pressure, end expiratory positive pressure and safety are pressed and all can be regulated on demand, and can show force value; (2) be continuous flow, can quicken the discharge of expired gas, prevent the suction that repeats of expired gas; (3), help the long period to use without air bag, laborsaving (needn't extruding gasbag can ventilate) operator's indefatigability; (4) superior performance, easy and simple to handle, be easy to grasp, safe and reliable, respond well, be more suitable for the clinical treatment needs, be suitable for delivery room, newborn room in each level medical institutions, baby's ward and operating room are applied.

Fig. 1 is this utility model package assembly sketch map.

Fig. 2 is this utility model structural representation.

Fig. 3 is the structural representation that Peak Inspiratory Pressure control valve and safety are pressed control valve.

Fig. 4 is the structural representation of end expiratory positive pressure control valve.

Describe this utility model in detail below in conjunction with accompanying drawing:

As shown in Figure 1, safety presses control valve, Peak Inspiratory Pressure control valve and air gauge to connect and compose the resuscitator main frame by pipeline, is arranged in the housing 9, and end expiratory positive pressure control valve and connecting line are separation member.

As shown in Figure 2, the oxygen feeder 1 that is connected with oxygen source is pressed control valve 3 with safety in turn by pipeline 2, Peak Inspiratory Pressure control valve 4 and end expiratory positive pressure control valve 5 link to each other, this pipeline 2 be by three tee Ts 7,7 ', 7 " and corresponding airway 6 is formed by connecting, and presses in safety between the pipeline of control valve and Peak Inspiratory Pressure control valve and is provided with air gauge 8.

As shown in Figure 3, relief valve is identical with Peak Inspiratory Pressure control valve structure, all be to be made of valve cylinder, flap, flap bar axle, spring, spring base and knob, wherein, the valve cylinder inwall has spiral lamination, bleeder port is offered in the barrel upper end, rotate the accent handle of adjust blood pressure button, the top cover of this button is moved forward and backward in valve cylinder, spring and flap are applied different pressure, regulate the escaped quantity of the interior gas of pipeline, use and set up and keep constant required Peak Inspiratory Pressure and safety pressure through flap and bleeder port.

As shown in Figure 4, the end expiratory positive pressure control valve is established a dividing plate above the air inlet in valve cylinder, passage is arranged on the dividing plate, and the central part on the dividing plate has goes up prominent adjust blood pressure awl post, pressure regulating cover is connected with the valve cylinder screw, caping central authorities are the gas outlet, and following connection surge pipe has the space between this surge pipe and the adjust blood pressure awl post, rotate pressure regulating cover, by the changes of voids of the adjust blood pressure mouth of pipe and adjust blood pressure awl intercolumniation, regulate the resistance that expired gas is applied, use and set up and keep constant end expiratory positive pressure.

Work process of the present utility model is as follows:

(1) setting up safety presses: 1. press control valve, Peak Inspiratory Pressure control valve and end expiratory positive pressure control valve to close safety, and the latter's caping mouth and patient interface stopped up; 2. open the oxygen cylinder oxygen supply; 3. slowly rotate counterclockwise the relief valve tuning knob, observe the atmospheric pressure value of air gauge indication simultaneously, be transferred to required safe pressure, generally than the high 0.5-1Kpa of required Peak Inspiratory Pressure, (2) set up Peak Inspiratory Pressure then, rotate counterclockwise Peak Inspiratory Pressure control valve tuning knob, are transferred to required Peak Inspiratory Pressure, (3) set up end expiratory positive pressure at last: 1. open end expiratory positive pressure control valve caping mouth, but still stop up the interface of this valve lower end; 2. rotate counterclockwise pressure regulating cover, be transferred to required end expiratory positive pressure, the adjust blood pressure process is all finished to this; (4) open interface, connect face shield or tracheal intubation, can carry out positive airway pressure; (5) vent method: with left hand fixed visors or tracheal intubation, the right hand is held outlet valve, when thumb is pinned the gas outlet of this valve gap face, promptly by the Peak Inspiratory Pressure of setting up to patient airway supply gas (air-breathing), decontrol finger, gas is promptly discharged (expiration) from the gas outlet of cap, and makes air flue keep the end expiratory positive pressure of setting up.
