The NO has a strong oxidizing property, the NO2 can be generated after the NO is reacted with oxygen in a respiration channel, the NO2 has strong irritation and corrosivity on the lung tissue after being inhaled, and the serious interstitial pneumonia and pulmonary edema can be caused. The nitric oxide inhaling therapeutic machine comprises a nitric oxide steel cylinder (1) which is connected with a flow controller (2) through a reducing valve (3), the flow controller is connected with an inspiration loop (5) of a breathing machine (4), the inspiration loop is connected with an expiration loop (6) of the breathing machine and a tracheal catheter (7) through a Y-shaped tee joint (8), the Y-shaped tee joint is connected with a collecting tube (9), the collecting tube is connected with a detecting instrument (10), a tail gas tube (11) is connected with the detecting instrument, and an NO exhaust gas adsorption device (12) is respectively connected with the tail gas tube and the breathing machine. The nitric oxide inhaling therapeutic machine is used for the inhalation therapy of the nitric oxide.
Description
technical field:
this utility model relates to a kind of Inhaled nitric oxide therapy machine.
background technology:
at present, low concentration nitric oxide (NO) sucks to be proved and can improve the epithelial function of protection lungs II type; Make the microcirculatory vasodilation of lungs, reduce pulmonary artery pressure; The hemoperfusion that increases lungs tissue, improves pulmonary ventilation/ventilation perfusion ratio, improves oxygenate, alleviates injury of lung and improves pulmonary function.If but the hemoglobin in the too high meeting of the inhaled concentration of NO and blood is in conjunction with generating metahemoglobin, affects the combination of oxygen in blood.In addition, itself has strong oxidizing property NO, and can produce NO after the oxygen effect of breathing in path
2
, NO
2
after suction, lung tissue is had to strong impulse and corrosivity, cause the generation of serious interstitial pneumonia and pulmonary edema.The safety of NO Inhalation in Treating becomes the problem that medical personnel and patient pay close attention to most, has had a strong impact on NO Inhalation in Treating in clinical extensively carrying out.
utility model content:
the purpose of this utility model is to provide a kind of Inhaled nitric oxide therapy machine.
above-mentioned object realizes by following technical scheme:
a kind of Inhaled nitric oxide therapy machine, its composition comprises: nitric oxide steel cylinder, described nitric oxide steel cylinder is connected by air relief valve with flow controller, described flow controller is connected with the air-breathing loop of respirator, described air-breathing loop is connected by Y-type three way type with expiration loop, the endotracheal tube of described respirator, described Y-type three way type is connected with collection tube, described collection tube is connected with detector, offgas duct is connected with described detector, and NO waste gas adsorber is connected with described offgas duct, described respirator respectively.

2
concentration detector, described NO concentration detector connect, described offgas duct respectively with described NO
2
concentration detector, described NO concentration detector connect.
embodiment 3:
according to the Inhaled nitric oxide therapy machine described in embodiment 1 or 2, described metahemoglobin monitor is connected with the probe 16 that same patient's finger joins.
embodiment 4:
described Inhaled nitric oxide therapy machine, in steel cylinder, the NO of 500ppm is through air relief valve, and flow controller is input to aspirating air pipe, mixes with suction gas (oxygen or air), by Y-type three way type transtracheal catheters or face shield, enters in patient body.At Y-type three way type, place is provided with sampling tube, gathers ducted gas, through high accuracy NO
2
and the detection of NO concentration detector, if exceed safety range (NO 90ppm, NO
2
5ppm) carry out sound and light alarm prompting, the tail gas after having detected reclaims and avoids air pollution through NO waste gas adsorber through pipeline and the ducted waste gas of exhaling.Can monitor the content of patient's total hemoglobin, HbO2 Oxyhemoglobin, metahemoglobin, the too high generation that causes patient's anoxia of prevention ferrihemoglobin content simultaneously.
