Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the carbon monoxide inhalation instrument includes a control part, a measurement circuit part and a CO and air mixing device.

[0017] The control part consists of: computer, data acquisition, control output, communication interface, and display. Realize the system interface operation through the computer, collect part of the data of the measurement circuit, analyze the data and output control instructions (output the instructions to control the solenoid valve for CO intake and the solenoid valve for air intake), and display the measurement and control results in real time.

[0018] The measurement circuit part is completed: the measurement circuit part converts the electrical signal converted by the sensor and amplifies and filters it, so that the signal is convenient for data collection. The measu...

Abstract

The invention discloses a carbonic oxide inhalator which comprises a control part, a measuring circuit part and a CO-air mixing device. The CO-air mixing device is provided with a CO inlet, an air inlet and a mixed gas outlet. The control part comprises a computer and a displayer. The measuring circuit part comprises a pressure sensor, a current amplifier, a filter and an A/D convertor, wherein the pressure sensor measures the gas pressure of input CO gas, air and mixed gas, current amplification and filtering are conducted on the gas pressure through the current amplifier and the filter respectively, then the gas pressure is converted into a digital signal through the A/D convertor and is input into the computer, and the computer analyzes data of the measuring circuit part and outputs a control command. The carbonic oxide inhalator is used for treating diseases such as pulmonary arterial hypertension, ARDS, respiratory failure caused by acute lung injury, hypoxic ischemic brain damage and shock.

Description

technical field [0001] The invention relates to a medical device, in particular to a carbon monoxide inhalation instrument. Background technique [0002] Carbon monoxide (CO) is an important endogenous mediator. CO can increase the level of cGMP in pulmonary vascular smooth muscle cells, lead to relaxation of pulmonary vascular smooth muscle, and selectively reduce pulmonary hypertension. Therefore, to explore the application of CO inhalation to treat pulmonary hypertension, acute pulmonary The value and significance of severe diseases such as respiratory failure caused by injury and ARDS are beginning to receive high attention, considering that some patients may not respond well and produce toxic nitrogen oxides during the treatment of widely used nitric oxide (NO) inhalation devices. problem, the new CO inhalation therapy has broad application prospects. However, there are no research reports and patent information on CO inhalation instruments and device technologies so f...
