Abstract
The utility model relates to a double-level respirator based on flow triggering, which comprises an air filter, a fan, a solenoid valve and a control system. The air filter, the fan and the solenoid valve are successively connected with each other. The control system electrically connected with the fan controls the operation of the fan. The control system comprises a CPU, a pressure flow sensor, an LCD display, an alarm and a key switch. The CPU is respectively and electrically connected with the air filter, the fan, the solenoid valve, the pressure flow sensor, the LCD display, the alarm and the key switch for controlling the operation thereof. The double-level respirator based on flow triggering has the advantages of safe usage, sensitive triggering, simple operation and the like.
Description
[technical field]
This utility model relates to a kind of two horizontal respirator that triggers based on flow, belongs to the armarium technical field.
[background technology]
Two horizontal BiPAP (Bi-Level Positive Airway Pressure) noninvasive ventilator has solved man-machine synchronous and gas leakage compensation problem under the noinvasive aeration condition preferably.Two horizontal positive pressure respirators are respirators of two pressure forms, and higher pressure of inspiration(Pi) is provided when the patient is air-breathing, to guarantee the opening of air flue, lower breath pressure are provided during expiration, and are smooth and easy to guarantee that the patient exhales.Advanced two horizontal positive pressure respirator has the respiratory triggering function, and pressure and flow can be synchronous with patient's autonomous respiration during treatment, thereby the level of comfort of treatment is improved greatly.Therefore, two horizontal respirators are the most comprehensively noninvasive ventilators of present function, necessary a kind of two horizontal respirator that triggers based on flow that improves structure that has are provided.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of safe in utilization, sensitive two horizontal respirator that triggers based on flow of triggering.
For realizing above-mentioned purpose, the technical scheme that this utility model is taked is: a kind of two horizontal respirator that triggers based on flow, and it comprises air filter, blower fan, electromagnetic valve and control system; Wherein, said air filter, blower fan and electromagnetic valve are connected successively; Said control system and blower fan electrically connect, and the operation of control blower fan; This control system comprises a CPU and pressure flow pick off, LCD display, alarm, key switch; Said CPU electrically connects respectively and the operation of control air filter, blower fan, electromagnetic valve, pressure flow pick off, LCD display, alarm and key switch.
The two horizontal respirator that triggers based on flow of this utility model further is set to: said control system is provided with an input power supply.
Compared with prior art, the utlity model has following beneficial effect:
1, trigger sensitivity, high respiratory frequency and low respiratory frequency can both well trigger and replace.
2, safety is secure, and patient can not accept long air-breathing malleation, avoids windage.
3, simple, to calculate easyly, the speed of service is fast.
[description of drawings]
Fig. 1 is the schematic diagram of the two horizontal respirators that trigger based on flow of this utility model.
[specific embodiment]
See also shown in the Figure of description 1, this utility model is a kind of two horizontal respirator that triggers based on flow, and it is made up of elements such as air filter 1, blower fan 2, electromagnetic valve 3 and control system 4.
Wherein, said air filter 1, blower fan 2 are connected with electromagnetic valve 3 successively, and air filters through air filter 1, and carry through blower fan 2, are defeated by the patient through electromagnetic valve 3 at last.
Said control system 4 electrically connects with blower fan 2, and the operation of control blower fan 2, thereby realizes the adjustment of air mass flow pressure.This control system 4 comprises a CPU41 and pressure flow pick off 42, LCD display 43, alarm 44, key switch 45.Said CPU41 electrically connects respectively and the operation of control air filter 1, blower fan 2, electromagnetic valve 3, pressure flow pick off 42, LCD display 43, alarm 44 and key switch 45.This CPU41 can judge according to its data that obtain, and then control the operation of entire equipment.Said control system 4 further is provided with an input power supply 46, for this respirator provides the energy.
The operation principle of the two horizontal respirators that trigger based on flow of this utility model is following: what this machine adopted is the flow triggering mode, according to the real-time change judgement patient present located breathing state of patient's air-flow, thereby makes corresponding response actions.The judgement of patient respiration state is carried out in variation through detecting flow; Flow curve is postponed 300ms and it is carried out translation to produce a signal curve, like this, when big variation takes place in gas flow rate; Signal curve and flow curve will intersect in the very first time; When signal curve and flow curve intersected, just meaning had had the change of breathing state this moment, and CPU41 will make the corresponding action adjustment.
In addition, this machine also can calculate patient's suction gas volume when gas flow rate increases.Just think when reaching certain volume that patient is carrying out inspiratory effort, respirator promptly provides air-breathing malleation response.
Aspect replacing,, also have Esens and replace method except having safing apneusis time and inspiratory airflow revolution replace.In suction condition, detect air-breathing peak flow velocity, think that when air-flow velocity drops to the Esens% of peak flow velocity patient begins to exhale, get into the expiration state.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
