The invention relates to medical technology, in particular to devices for moistening respiratory mixtures, for example, in ventilators.

The purpose of the invention is to increase patient safety by preventing overheating of the breathing mixture and the ingress of steam into the respiratory tract.

The drawing shows a schematic diagram of the humidifier.

The humidifier contains an evaporator 1, made in the form of an L-shaped glass tube, one end of which is connected to the inspiration hose 2 and the other to the hose 3. A hose 3 connects the evaporator 1 to the indicator-regulator 4 of the fluid supply and has a vapor discharge port 5 on which the blocking solenoid valve 6 is installed. The indicator-regulator 4 of the fluid supply consists of a clamp 7 and a transparent drip 8, which is connected to the reservoir

voara to the entire humidifier. Since the internal diameter of the evaporator tube is small, the pressure of the gas mixture insignificantly affects the rate and uniformity of water entering the evaporator 1. The saturation of the gas mixture with steam is controlled by the rate of water supply and the degree of heating of the evaporator tube. The heating temperature in this case is regulated by means of a switch- 10 bodies (not specified), which can be used as a rheostat. In case the heating elements are made as separate components, the heating temperature is regulated by sequential

with their inclusion. When the temperature rises above the critical temperature (38-40 ° C), the thermal sensor is turned on AND with the regulator 12. Valve 6 opens, vapor and liquid are released from the evaporator 1 (due to the pressure difference in the inspiratory hose 2 and outflow of the liquid (not shown) Evaporator 1 20 ritori 1). There is a rapid decline.

and the inspiratory hose 2 is located inside the heating elements 9 and 10. The humidifier has a temperature control system consisting of a temperature sensor 11, a regulator 12 and a shut-off solenoid valve 6.

The heating elements 9 and 10, the evaporator 1 and the inhale hose 2 are located in a thermally insulating material 13, such as foam plastic.

After installing the humidifier in the appliance of the compactness and lightness, on any type of artificial ventilation of the lungs and oxygen sub-oxygen inhalers and anesthesia to the patient, they include heater-parats, which greatly expands the spheral elements 9 of the evaporator 1. In the case of . In addition to the gas mixture, the mixture is very cooled, or humidified, easily disassembled.

there is a danger of condensation in excess, simultaneously with the heating elements 9 include heating elements 10 of the heated inspiration hose 2. After that, start the flow of water from the tank to the evaporator 1 through the indicator-regulator 4 of the fluid supply. For ease of use, a tank is placed, for example, on a tripod, and its height is calculated so that the water itself enters the table.

Claims. A humidifier containing an evaporator with a heating element and a temperature control system containing a temperature sensor located at the outlet of the inspiratory hose, a regulator and an executive the steamer is due to the difference in height between the intermechanisms, characterized in that reservoir and actually a sweeper. At the same time, the excessive flow of water to the evaporator is eliminated by the clip 7, which, by reducing the clearance of the flexible tube, controls the rate of flow of water. Water is monitored visually and is determined by the number of droplets falling in the drip over a certain amount of time, as well as the level of the patient's safety retracement height by preventing overheating of the breathing mixture and steam ingress into the respiratory tract; a pair located between the indicator-regulator and the evaporator, and the actuator is designed as a shut-off valve and is installed on the steam discharge pipe. voara to the entire humidifier. Since the internal diameter of the evaporator tube is small, the pressure of the gas mixture insignificantly affects the rate and uniformity of water entering the evaporator 1. The saturation of the gas mixture with steam is controlled by the rate of water supply and the degree of heating of the evaporator tube. In this case, the heating temperature is regulated by means of a switch-0-body (not specified), which can be used as a rheostat. In case the heating elements are made as separate components, the heating temperature is regulated by sequential with their inclusion.

There is a rapid decline. temperature in the evaporator 1 and the hose 2 breaths. In this way, a stable moistening of the breathing mixture is achieved, uniformly heating it at different gas flow rates and ensuring sufficient protection against overheating and ingress of steam into the patient's respiratory tract. In addition, the humidifier is simple, compact and easy to handle. It can be used both in stationary and in less adapted conditions, and for cleaning, washing and subsequent disinfection or sterilization. Claims. A humidifier containing an evaporator with a heating element and a temperature control system containing a temperature sensor located at the outlet of the inspiratory hose, a regulator and an executive to increase patient safety by preventing overheating of the respiratory mixture and steam ingress into the respiratory tract, it is equipped with a liquid supply control indicator and a steam discharge pipe located between the control indicator and the evaporator, and the actuator is designed as a shut-off valve and is installed on the discharge pipe couple.
