Abstract
The invention relates to an electric control end-expiratory positive pressure expiratory valve used on an electric respirator. An electric control end-expiratory positive pressure expiratory valve system consists of an expiratory valve body 7, an expiratory valve core 6, a membrane 5, a membrane 4, an expiratory end cover 3, an electromagnet coil 2 and an electromagnet core 1. The electric control end-expiratory positive pressure expiratory valve can accurately control the end-expiratory positive pressure of patients under the control of a microprocessor. The invention provides a method of the electric control end-expiratory positive pressure expiratory valve used on an electric respirator.
Description
Technical field:
The present invention relates to the method for a kind of electric pulmotor, belong to the biomedical engineering technology field with electric control end-expiratory positive pressure expiratory valve.
Background technology:
Positive end expiratory pressure refers to that ventilator produces malleation in inspiratory phase, and gas is pressed in the lung; But in end-tidal, airway pressure does not reduce to zero, and remains on certain malleation level.Principal indication is the hypoxemia due to the QS pulmonary shunt.Positive end expiratory pressure is corrected the mechanism of hypoxemia: positive end expiratory pressure helps alveolar and still keeps expanding in end-tidal, and can prevent the closure of little air flue, its physiological action is: reduce alveolar and wither, reduce QS pulmonary shunt, correct the low pneumophemia due to the QS pulmonary shunt; Increase FRC, help the abundant exchange of alveolar-blood capillary both sides gas.The main purpose of using end expiratory positive pressure is increase lung volume, improves Map power, improves oxygenate.In addition, end expiratory positive pressure can also be offseted intrinsic positive end expiratory pressure, reduces the inspiration trigger merit that intrinsic positive end expiratory pressure causes.General electric pulmotor is owing to do not control gas when exhaling, so generally all adopt manual adjustments end expiratory positive pressure value.And manual adjustments end expiratory positive pressure value can not accomplish convenient adjusting accurately to have certain defective.The electric control end-expiratory positive pressure expiratory valve of the electric pulmotor that abroad has at present is automatically controlled fully, has slow shortcoming of response time.
Summary of the invention:
The objective of the invention is to provide a kind of method or device of electric control end-expiratory positive pressure expiratory valve at above-mentioned deficiency.The present invention can control patient's end expiratory positive pressure accurately under microprocessor control; Have simple in structure, long, cost performance advantages of higher of life-span.
Technical scheme of the present invention is: the electric control end-expiratory positive pressure expiratory valve system that electric control end-expiratory positive pressure expiratory valve of the present invention is made up of expiration valve body 7, expiration spool 6, diaphragm 5, diaphragm 4, expiration end cap 3, electromagnet coil 2, electromagnetic core 1.During work, when electric pulmotor was not provided with the end expiratory positive pressure value, electric magnet did not have adhesive, and electromagnetic core is not closed outlet valve, at this moment, and the opening or closing of the control gas control system outlet valve that outlet valve is sent here by electric pulmotor fully.When electric pulmotor is provided with the end expiratory positive pressure value, in the patient inhales stage, close by the control gas control system outlet valve that electric pulmotor is sent here, make patient inhales; In the patient exhales stage, the initial stage of patient exhales, control gas in the outlet valve is discharged control gas by electromagnetic core 1, outlet valve is unlimited fully, and patient normally exhales, when the pressure of patient expired gas drops to the end expiratory positive pressure value of electric pulmotor setting, electromagnetic actuation, electromagnetic core 1 is closed outlet valve, remains to air-breathing beginning always, and the pressure in the corrugated hose maintains the end expiratory positive pressure value of setting at this moment.
The advantage of electric control end-expiratory positive pressure expiratory valve of the present invention is to control the end expiratory positive pressure value accurately, and does not influence the response time that outlet valve opens and closes; The present invention is used on the electric electricing breathing machine, and outlet valve only is being provided with the end expiratory positive pressure value and when breath pressure reaches the end expiratory positive pressure value, and just adhesive of electric magnet is so there is the advantage of saves energy; Because at the initial stage of exhaling, electric control end-expiratory positive pressure expiratory valve is opened fully, can not produce resistance to exhaling, institute so that patient exhales as snug as a bug in a rug.
