Background technique

Respiratory medicine often uses the method of atomization therapy, and the drug directly contacts the affected part in the form of atomization, which can play a better therapeutic effect.

The aerosolized drug delivery in the prior art mostly involves inhaling the gas with the aerosolized medicine into the trachea and bronchus by means of patient inhalation, which has certain defects, specifically:

1. Due to the lack of lung function of patients in the respiratory department, their inhalation power is limited, even shallow breathing, and the depth of inhalation is not enough, which easily leads to insufficient contact between the atomized gas and the inner wall of the trachea or bronchus, thereby delaying the recovery of the disease;

2. The patient inhales the nebulized gas by inhaling, and the nebulized gas is subject to little disturbance. The nebulized gas in the patient's trachea or bronchi is in contact with the inner wall of the trachea or bronchus in a natural way, and its diffusion direction has a certain direction. Limited, it is easy to cause uneven diffusion angle, so that the patient's tracheal wall or bronchial wall cannot receive the drug evenly, thus affecting the treatment effect;

3. In the prior art, the atomizing mask is provided with a nasal mask, and the nasal mask is the place to accommodate the atomized gas, but because the width and height of the nasal mask are obviously larger than the diameter of the atomized gas pipeline, once the atomized gas enters The nasal mask will spread in the nasal mask, which will easily lead to the waste of atomized gas.

The atomization pipe joint 4 is connected with the atomization device 3, and the atomization device 3 is connected with the medicine storage container 1 through the flow pump 2;

The tail end of the inflatable ball 20 is connected to the oxygen cylinder 23 through a third connecting pipe 21 provided with a pressure reducing valve 22 .

As shown in Fig. 1, the present invention is provided with a screw pressurizing unit. When in use, the patient wears the mask body 8, holds the gas flowing to the outer wall of the converter with one hand, and presses the inflatable ball 20 with the other hand, and the pressure gas passes through the first pressure The chamber 16 flows into the second pressure chamber through the air hole 5, and then enters the helical dosing chamber 6 through the helical air hole channel 15; as shown in FIG. The direction is transmitted to the spiral dosing chamber 6, so that the atomized gas is disturbed in a spiral shape, and the atomized gas rotates in the spiral dosing chamber 6, and the rotation direction 25 of the atomized gas is the spiral propulsion as shown in Figure 2. ; As shown in Figure 1, the atomized gas is spirally pushed into the mask body. When the patient inhales the atomized gas forcefully, due to the sufficient spiral disturbance of the atomized gas, it is fully in contact with the inner wall of the trachea or bronchus, so The treatment effect will be better.

Example 2:

This embodiment is a further improvement made on the basis of Embodiment 1, specifically:

As shown in FIG. 1 and FIG. 2 , the mask unit includes a mask body 8 and a nasal mask 11 arranged in the mask body 8 , and the nasal mask 11 communicates with the first connecting pipe 13 ;

The end of the first connecting pipe 13 facing the nasal mask 11 is provided with a three-way joint 12, and the three-way joint 12 is connected with two nasal tubes 10 for ventilating the nose. The nasal tubes 10 extends into the nasal mask 11;

On the basis of the above description, during use, the patient presses the inflatable ball 20 and cooperates with deep inhalation. The atomized gas enters the patient's respiratory tract from the nasal tube 10 in a spiral shape. At this time, the patient temporarily shields the breathing through the mouth and nose, so that the atomized gas diffuses in the trachea or bronchi. The nasal tube 20 fully retains the pressure of the atomized gas, and the inhalation process of the patient will be more labor-saving. Moreover, the atomized gas with spiral disturbance and sufficient pressure can better treat the patient's respiratory tract. At the same time, after the spiral disturbance The atomized gas can avoid the limitation of the diffusion direction caused by the natural dispersion of the atomized gas in the patient's respiratory tract in the prior art (just like smoke floating in the air, its diffusion direction always has a certain angle, and through the spiral After the shape disturbance, its diffusion direction can be close to the uniform diffusion to the surrounding area), so as to achieve a better therapeutic effect.

Since the atomization operation is performed under the patient's own control, the new model can adjust the impact force of the atomized gas on the respiratory tract by pressing the inflatable ball, so it can avoid respiratory discomfort caused by high gas pressure.

Among them, it is recommended to use a hard pipe for the first connecting pipe 13, and connect the conical joint 7 with a smaller length, so that the power consumption of the spiral-shaped atomizing gas during the transmission process can be reduced.
