Description
Technical field
This utility model relates to a kind of breathing equipment, relates in particular to a kind of computer infant high frequency respirator.
Background technology
As everyone knows, infant is existing very big difference with the adult aspect the health physiological structure, children respiratory is long and narrow, physiologic dead space is big, lung compliance is poor, in case occur selecting when discomfort particularly needs ventilation therapy the kind of respirator particularly crucial, the clinical practice respirator mostly is the enclosed conventional ventilation mode of CMV at present, though and such respirator is a kind of traditional breathing pattern, but have the following disadvantages: as cost an arm and a leg, make complicated, operate cumbersome, attached accessory rapid wear and be difficult to prepare.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of prior art, provide a kind of simple in structure, convenient and practical, cost is low, it is simple to make debugging, processing ease, the computer infant high frequency respirator of suitable many conventional diseases.
This utility model is realized by following scheme: comprise shell, computer motherboard, intake interface, the interface of giving vent to anger, master control electromagnetic valve, output pressure control valve, pressure-display device, ejector pin, pressure measurement interface, it is characterized in that: also comprise PEEP electromagnetic valve, PEEP output adjust valve, air inlet cross joint, output gas cross joint and external empty oxygen mixings needle stand composition.Pressure-display device comprises that two show row, intake interface is connected to the air inlet joint that crosses by the output pressure control valve and is connected to the master control electromagnetic valve again, be connected to the output gas joint that crosses,, be transported to ejector pin in the sky oxygen mixing needle stand through breathing output pipe by the interface of giving vent to anger; Another road gas is to be connect in the lump pipe to PEEP output and adjusted valve by the air inlet joint that crosses, be connected to the PEEP electromagnetic valve again, cross joint to the interface of giving vent to anger by output gas, the ejector pin of delivering in the sky oxygen mixing needle stand is exported in the merging that forms two-way gas, connect one road gas to the sigh electromagnetic valve at the air inlet joint that crosses, be connected to the output gas joint that crosses and export by the gas outlet.Computer motherboard sampling from output gas adds to the pressure transducer on the mainboard, delivers to by the conversion of microcomputer to show that row is to show the force value of output tolerance; Connect gas the air flue from the pressure measurement interface of corrugated hose, sampling is connected to another pressure transducer on the mainboard, delivers to by the conversion of microcomputer to show that row shows the airway pressure value.
This utility model also has additional humidifying interface, humidifying joint, humidifier and humidifying control valve, intake interface connect one road gas to the humidifying control valve to the humidifying interface, receive again that humidifier carries out humidifying after the humidifying joint is received the mixing needle stand.
This utility model and high frequency ventilation is compared its unique advantage in the clinical practice of department of pediatrics with the CMV of routine: the tidal volume of high frequency ventilation near or be lower than the anatomical dead space amount, ventilation period average and maximum airway pressure are lower, thereby are of value to blood circulation.Being of value to cardiac output increases, and also benefits oxygenate; Conventional CMV ventilation is then closed with the ventilation of the big tidal volume of low frequency and air flue usually has higher expansion to press, the air flue peak value is pressed and is caused that easily epithelial albumen oozes out the formation windage, and high frequency ventilation expansion pressure reaches good gas exchange than mental retardation, thereby reduce the generation of the minimizing windage that breaks that prevents alveolar, the suitable relatively poor infant of lung compliance; Intrathoracic pressure still is a negative pressure during the high frequency ventilation, the distributional class of gas is similar to autonomous respiration in the lung, thereby this slight pressure side changes the conduction impulsion that has suppressed respiratory center has suppressed autonomous respiration, make the infant mechanical ventilation be easy to coordinate, and reduced and breathed antagonism, also having reduced ataractic use thus is of value to withdrawing of respirator; Adopting during high frequency ventilation does not have cover capsule and thinner endotracheal tube, expired gas from conductance both sides mouth overflow and resistance little, help the discharge of carbon dioxide, and CMV when ventilation conduit sleeve bag gas-filling forms mucosa compressing necrosis easily and the expired gas resistance is big, hinder the discharge of carbon dioxide to influence the oxygenate function; Expansion of lower air flue and less tidal volume are difficult for the infringement pulmonary surfactant during high frequency ventilation, and airway pressure intermittently raises and holds infringement lung surface active goods and materials reduction oxygenate effect during the CMV ventilation; During high frequency ventilation since in airway open ventilation and the air flue attraction can carry out simultaneously, bring out the best in each other, and air flue closes during the CMV ventilation, attract and ventilate and can't carry out simultaneously, Chang Yi causes patient's hypoxemia even respiratory arrest.This utility model is simple in structure, convenient and practical, cost is low, it is simple to make debugging, processing ease, and suitable many conventional treatment of diseases are as respiratory failure, respiratory distress syndrome, pulmonary edema, the suffocating of pneumorrhagia a variety of causes, cardiopulmonary arrest, respiratory disorders such as severe asthma.Primary premature or insecondary asphyxia, central respiratory failure, central nervous system disorders such as respiration inhibition.Breathing fatigue due to a variety of causes, breathing shoals, the sick and weary diseases of respiratory muscle such as contradiction breathing and periodic asphyxia.And the breathing assisted ventilation of the breathing management of heart, chest, the operation of congenital diaphragmatic hernia etc.
