The one-way valve switch contains a ventilation pipe, and the top of the ventilation pipe is movably connected with an elastic film through an elastic pressing piece.

As a preferred technical solution of the present utility model, a sealing ring is tightly installed at the port of the trachea connecting pipe.

As a preferred technical solution of the present invention, the radius of the elastic film is larger than the radius of the air duct.

As a preferred technical solution of the utility model, the ventilator host is electrically connected to the one-way electromagnetic valve and the valve one-way electromagnetic switch respectively.

The beneficial effects achieved by the utility model are: the utility model has a compact structure and is convenient to use, and solves the difficult problem that patients need atomization treatment while using an invasive ventilator in clinical practice. That is, it can always ensure the positive pressure ventilation of the ventilator, does not reduce the positive end-expiratory pressure to prevent alveolar collapse, and can carry out drug nebulization treatment at any time, and can synchronize the inhalation of nebulized drugs with the ventilator to achieve better results. The effect of this method completely solves the problem of pressure reduction in the ventilator pipeline, has good economic and social benefits, and is suitable for popularization and use.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment of the present utility model: the structure schematic diagram of the atomization mist storage device of the new electronic control ventilator is shown in Fig. 4. Valve one-way electromagnetic switch 5, pressure reducing valve 6, adapter 7, one-way valve switch 8, trachea connecting pipe 9, sealing ring 10, elastic pressing piece 11, elastic film 12 and ventilation pipe 13, mist storage One end of the tank body 4 communicates with the ventilator host 1 through the ventilator intake pipe 2, and a one-way solenoid valve 3 is installed in the middle of the ventilator intake pipe 2, and an adapter 7 is embedded in the bottom of the mist storage tank body 4, and the adapter 7 is connected to the ventilator main body 1. The joint of the mist storage tank body 4 is provided with a flap one-way electromagnetic switch 5, the side end of the adapter 7 is equipped with a pressure reducing valve 6, the other end of the mist storage tank body 4 is provided with a trachea connecting pipe 9, and the inner middle of the trachea connecting pipe 9 A one-way valve switch 8 is installed, and the one-way valve switch 8 includes a vent pipe 13 , and the top of the vent pipe 13 is movably connected with an elastic membrane 12 through an elastic pressing piece 11 .

A sealing ring 10 is tightly installed at the port of the trachea connecting pipe 9, which ensures the tightness in the pipeline and prevents gas from flowing out.

The radius of the elastic film 12 is larger than the radius of the air duct 13, which ensures that the elastic film 12 can only move to the side of the air duct 13.

The ventilator host 1 is electrically connected to the one-way solenoid valve 3 and the valve one-way electromagnetic switch 5 respectively. Periodically open, so that the nebulized medicine enters the spacer tank body 1 for storage, so that the medicine can be brought into the patient's respiratory tract when the ventilator is inflated next time. And when the ventilator host 1 is in the state of supplying air, the one-way electromagnetic valve 3 is opened, and the valve one-way electromagnetic switch 5 is closed, thereby ensuring the pressure in the airway.

Specifically, when in use, the ventilator intake pipe 2 is connected to the ventilator main body 1, and the trachea connecting pipe 9 is connected to the trachea. 1. Open the intermittent period when the air supply is stopped, so that the nebulized medicine enters the spacer tank 1 for storage, so that the medicine can be brought into the patient's respiratory tract when the ventilator supplies air next time. And when ventilator main frame 1 is in gas-supply state, one-way electromagnetic valve 3 is opened, valve one-way electromagnetic switch 5 is closed, has guaranteed the pressure in the airway, and one-way valve switch 8 can only be opened to the left side, when patient is in In the state of exhalation, the elastic film 12 is closely attached to the port of the ventilation pipe 13, and the one-way valve switch 8 is closed to ensure that the ventilator pipeline is in a normal pressure state, and the gas exhaled by the patient can pass through the exhalation of the ventilator.
