Description
Technical field
This utility model relates to a kind of device that is mainly used in the control of artificial airway's gasbag pressure continuous monitoring in the medical treatment, for the control of respirator dependency pneumonia provides the critical treatment means.
Background technology
Mechanical ventilation is the effective ways of the acute and chronic respiratory failure due to rescue and the treatment a variety of causes; In clinical critical patient's rescue, used widely; But respirator dependency pneumonia (abroad report by ventilator associated pneumonia, VAP) this complication rate sharp increase thereupon; The VAP sickness rate reaches 9%～70%, and case fatality rate is up to 50%～69%.Domestic have a research, and sickness rate is 43.19%, and case fatality rate is 51.6%, becomes the very important factor of nosocomial infection.
The important channel that VAP takes place comes from upper respiratory tract stomach function regulating intracavity field planting bacterium mistake and inhales.The barrier of tracheal intubation pars oralis pharyngis and lower respiratory tract is directly impaired, and field planting is gone into lower respiratory tract upper respiratory tract cause of disease bacterium through the mistake inspiration, and patients with mechanical ventilation is in a bad way or underlying diseases is often arranged, and the oral cavity bacterium field planting very easily occurs.Have report patients with mechanical ventilation 9%～70% that aspiration pneumonitis can take place, its reason sucks relevant with gastric content.Therefore prevention mistake is inhaled the important means that becomes prevention and control VAP.
Recommend according to VAP prevention and control guide; Adjustment artificial airway gasbag pressure, the sustained sound student attract, raise head of a bed height, monitoring gastric content residual volume; Be the boundling strategy that prevents that mistake from inhaling, be proved to be the incidence rate that can reduce VAP, it is 25～30cmH that guide is recommended ideal gasbag pressure
2O reaches closed airway, avoids the effect of air flue mucosa ischemia injury simultaneously; And the assurance of gasbag pressure becomes a clinical difficult problem; Guideline recommendation is carried out three monitorings and adjustment every day, but there are some researches show, the piezometry value of carrying out for three times every day before the air bag pressure measurement still maintains 25～30cmH
2The person is merely patient's pressure of 36.7%, 60.2% and is lower than 25cmH in the O
2O, the risk that the mistake suction takes place obviously increases, and patient's pressure of 3.1% is higher than 30cmH
2The airway pressure damage takes place in O easily, is difficult to realize and increase more clinical personal monitoring's frequency.
These problems directly cause the patient safety problem, therefore, need a kind of pressure control device, realize inflating automatically, exit, guarantee that its pressure is at confidence band.
Several kinds of pressure control devices are in fact arranged in the market; A kind of is the mechanical aeration device of the formula of injecting, a kind of be ball by aerating device, they all have a Pressure gauge; This device advantage is: realized Manual pressure control; Shortcoming is to need manual work to charge and discharge gas, does not carry out intelligentized pressure control, and can not carry out successive monitoring and regulate automatically.In prior art, also there is not the gasbag pressure control device of intelligent automatic controlled pressure at present.
