Humidifier of breathing mixtures and medical gases
The humidifier for medical gases produced by “DONMET” can be supplied both separately and as a part of pressure regulators with flow meters. For regulators with a humidifier, the oxygen cylinder must be installed on a solid surface that ensures its stability. After the end of its useful life, the humidifier does not pose a danger to life, health of people or the environment and cannot cause damage to the property of citizens. Therefore, the designated resource, designated service life, designated storage period, after which the operation of humidifiers must be stopped regardless of their technical condition, is not established. Due to the absence of heating elements in the humidifier, this type of humidifier cannot be used in patients with a tracheostomy or tracheal shunt of the supraswallowing airways. The temperature of any material in the design of the humidifier does not exceed the minimum permissible level of ignition, both under normal operating conditions and under single failure conditions. There are no data on the possibility of using a humidifier for intubated patients and connecting to a positive pressure ventilator. There is no data on the suitability of the moisturizer for use with anesthetic agents.
The humidifier for the regulator consists of the following elements:
— an adapter with a M16x1.5 nut (lens) for connecting to the output connector of the regulator, with a nipple Ф4.5 for connecting a cannula (Dy -3mm) and a nipple for connecting a siphon tube;
— food PET bottle with a 0.5l volume for distilled water;
— a siphon tube.
