Description

A non-invasive ventilator mask

technical field

The utility model relates to the technical field of medical care equipment, in particular to a novel non-invasive ventilator mask.

Background technique

Ventilator is a device that can replace, control or change normal physiological respiration, increase lung flux, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity. The ventilator used clinically generally consists of a mask, a pipeline part and a breathing pacemaker. The mask is worn on the mouth and nose of the patient. The existing mask fits the surface of the human face, and has an air supply port and an oxygen input port of the ventilator, and oxygen is blown into the patient's mouth and nose through the air supply port.

The mask with the above structure is in use, because the ventilator is in the airtight mask environment, and the air is blown out for a long time, and the humidification is not enough, which will easily cause the patient's mouth and nose to be dry, and the airway cilia to swing, which will increase the probability of lung infection. , clinically use a separate nebulizer for antiphlegm treatment, this nebulizer needs to remove the ventilator mask and use it alone. Repeated alternate use is cumbersome and affects the therapeutic effect.

Utility model content

In order to overcome the above-mentioned shortcomings of the existing ventilator mask, the utility model provides a non-invasive ventilator mask which simultaneously performs atomization and improves the effect of assisted breathing.

In order to achieve the above object, the utility model adopts the following technical solutions:

In the non-invasive ventilator mask of the utility model, the mask body is provided with an air supply port and an oxygen supply port of the ventilator, and the mask body is also provided with an atomizer connecting pipe.

As a perfection of the above scheme, a flow control valve is installed on the inlet pipe of the atomizer, the flow control valve includes a baffle, a control rod and an adjustment knob, and the control rod passes through the wall of the inlet pipe of the atomizer, One end of the control rod is connected to the baffle, and the other end is connected to the adjustment knob. The baffle is a disc with the same diameter as the atomizer inlet pipe and is installed in the atomizer inlet pipe.

Compared with the prior art, the beneficial effects of the utility model are:

1) Set the nebulizer access tube, connect the nebulizer to humidify the oxygen in the mask, increase the humidity of the inhaled gas, improve the quality of the inhaled gas, and improve the effect of assisted breathing.

2) There is an atomization flow control valve, which can switch or adjust the atomization flow according to the needs, which is flexible and convenient to use.

Description of drawings

Fig. 1 is a schematic structural view of a novel non-invasive ventilator mask of the present invention.

In the figure: 1. Mask body; 2. Air supply port; 3. Oxygen delivery port; 4. Atomizer connection tube;

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Example 1

As shown in FIG. 1 , the non-invasive ventilator mask of the present invention has a ventilator air supply port 2 and an oxygen supply port 3 on the mask body 1 , and an atomizer inlet pipe 4 is also provided on the mask body 1 .

As a perfection of the above scheme, a flow control valve is installed on the connection pipe 4 of the atomizer, and the flow control valve includes a damper 5, a control rod 6 and an adjustment knob 7, and the control rod 6 passes through the connection pipe of the atomizer. The tube wall of the inlet tube 4, one end of the control rod 6 is connected to the baffle 5, and the other end is connected to the adjustment button 7, the baffle 5 is a disc with the same diameter as the atomizer inlet tube 4, and is installed in the atomizer inlet tube 4 .

The nebulizer connecting pipe 4 is set, and the nebulizer is connected to humidify the oxygen in the mask, so as to increase the humidity of the inhaled gas, improve the quality of the inhaled gas, and improve the assisted breathing effect.

An atomization flow control valve is provided, and the damper 5 can be controlled by adjusting the adjustment knob 7 and the atomization flow can be adjusted according to needs, which is flexible and convenient to use.
