Embodiment Construction

[0047] Below, while referring to the attached Figure 1 Embodiments of the present invention will be described in detail. Throughout the drawings, common reference numerals are assigned to corresponding constituent elements.

[0048] figure 1 It is a schematic diagram of the nitric oxide dosing device 1 . The nitric oxide dosing device 1 has: a first flow path 101, equipped with an air inlet 101a and an oxygen supply port 101b; Oxygen; the second flow path 201 is branched from the first flow path 101 and is provided with a NO supply port 201b; the NO generation unit 200 is arranged in the second flow path 201, and generates NO from the gas distributed from the first flow path 101; part 300; and box 400. The oxygen generator 100 , the NO generator 200 , and the control unit 300 are housed in the same housing 400 . Concentrated oxygen generated by the oxygen generator 100 is supplied through the oxygen supply port 101 b and the cannula 410 . NO generated by the NO generati...

Abstract

A nitric oxide administration device 1 comprises: a first flow channel 101 provided with a first intake port 101a and an oxygen supply port 101b; an oxygen generating unit 100 which is disposed in the first flow channel 101 and which generates concentrated oxygen from air flowing in via the first intake port 101a, the concentrated oxygen generated by the oxygen generating unit 100 being supplied via the oxygen supply port 101b; a second flow channel 201 which branches from the first flow channel 101 and is provided with an NO supply port 201b; and an NO generating unit 200 which is disposed in the second flow channel 201 and which generates NO from a gas distributed from the first flow channel 101, the NO generated by the NO generating unit 200 being supplied via the NO supply port 201b.

Description

technical field [0001] The invention relates to a nitric oxide dosing device (NO dosing device). Background technique [0002] Pulmonary hypertension is a disease in which the blood pressure (pulmonary artery pressure) of the pulmonary artery, which is a blood vessel leading from the heart to the lungs, becomes high. Pulmonary hypertension is classified in groups 1 to 5 in the Nice Classification [2013]. In group 3 pulmonary hypertension accompanied by pulmonary disease, hypoxemia. One of the treatments for pulmonary hypertension includes home oxygen therapy (HOT). When home oxygen therapy is administered to a patient with pulmonary hypertension, although a partial progress-inhibiting effect of pulmonary hypertension appears due to the vasodilation effect due to the release of vasospasm, normalization of pulmonary arterial pressure cannot be expected. On the other hand, nitric oxide (NO) is one of the vasodilators that selectively dilate blood vessels around ventilated al...
