Description

Structure is collected to breathing machine pipe comdenstion water

Technical Field

The utility model relates to an articles for use field of hospital especially relates to a structure is collected to breathing machine pipe comdenstion water.

Background

The ventilator tube is a medical line used for connecting a ventilator and guiding the gas output by the ventilator to the respiratory tract of a patient. The ventilator has a humidification tank for heating humidified gases to ensure that gases inhaled by the patient have sufficient humidity to avoid drying the airways. The temperature of the heated and humidified gas is reduced in the process of conveying the gas through the breathing machine pipe, so that condensed water can be generated in the breathing machine pipe. In order to avoid that the condensed water enters the airway of the patient, a structure for collecting the condensed water is arranged on the respirator pipe.

The structure is collected to breathing machine pipe comdenstion water includes drain pipe, connection lid and drinking cup, and the drain pipe setting is on the breathing machine pipe, is the Y venturi tube usually, connects the center and the water piping connection of lid, and the drinking cup can be dismantled with the connection lid and be connected. The water cup needs to be vertically arranged so that condensed water can be effectively collected; if the cup is horizontal or inclined, the amount of water which can be collected is reduced; if the cup is inverted, condensed water cannot be collected. In clinical practice, the ventilator tube may move due to patient movement or other reasons, which may cause the position of the cup which is vertically arranged originally to change. If water is collected in the cup, the change of the position of the cup to the inclined or horizontal position can cause the condensate water to flow back to the respirator tube, and the change of the position of the cup to the inverted position inevitably causes the condensate water to flow back to the respirator tube, so that a patient can inhale the condensate water to cause choking and other more serious risks.

In order to avoid the above situation, some respirator tube condensate water collection structures have appeared that prevent the water collected by the cup from flowing back. For example, ZL202022521183.5 discloses a condensed water backflow prevention water accumulation cup which comprises a water accumulation cup body, wherein an accommodating cavity is formed in the water accumulation cup body, an interlayer is arranged in the accommodating cavity, the accommodating cavity is divided into an upper accommodating cavity and a lower accommodating cavity by the interlayer, and a check valve is arranged in the middle of the interlayer; a Y-shaped connecting pipe connected in series on a breathing machine pipeline is arranged above the water accumulation cup body, the Y-shaped connecting pipe comprises a vertical pipe and two inclined pipes, and the vertical pipe is communicated with the upper accommodating cavity; the inclined pipe is communicated with a breathing machine pipeline; the condensed water in the breathing machine pipeline flows to the upper part accommodating cavity along the vertical pipe through the inclined pipe, and the condensed water in the upper part accommodating cavity flows into the lower part accommodating cavity through the one-way valve.

The patent states that the arrangement of the interlayer in the water accumulation cup and the check valve on the interlayer can enable condensed water in the upper accommodating cavity to flow into the lower accommodating cavity through the check valve and can prevent the condensed water from flowing back into the upper accommodating cavity from the lower accommodating cavity. However, the conventional check valve is opened by a certain pressure, and the water in the upper receiving chamber is only opened when a sufficient water pressure is accumulated to a sufficient level and flows into the lower receiving chamber, and after the water flows down, the water cannot flow down due to insufficient water pressure. But also the air pressure in the lower receiving chamber. Therefore, the water accumulation cup cannot actually prevent the water from flowing backwards.
