Detailed ways

The technical scheme of the utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited to the following description.

As shown in Figures 1 and 2, a high-efficiency inhalation spacer for making breathing smoother comprises a spacer body 1, a front end cover of the spacer 2 installed at the front end of the spacer body 1, a spacer cover 2 installed at the front end of the spacer body, The rear end cover 3 of the spacer at the rear end of the body 1 and the ventilation diaphragm 4 arranged between the body 1 of the spacer and the front end cover 2 of the spacer; the front end of the front cover 2 of the spacer is provided with a suction port 21. The suction port 21 is a convex-shaped suction port. The mask 5 is set on the convex-shaped suction port and forms an interference connection with the convex-shaped suction port. The patient passes through the mask 5 and the convex-shaped suction port. Perform inhalation and exhalation to achieve treatment; the rear end cover 3 of the spacer is provided with an inhaler insertion port 31 and a vent 32 indirectly connected with the body of the spacer 1, and an aerosol inhaler (MDI) 6 The insertion port 31 of the inhaler communicates with the inner cavity of the spacer body 1 , so that the medicine ejected from the aerosol inhaler (MDI) 6 can be stored in the spacer body 1 .

As shown in Figure 3, the ventilation diaphragm 4 is provided with an inspiratory one-way diaphragm 41 and an exhalation one-way diaphragm 42, and the inspiratory one-way diaphragm 41 and the exhalation one-way diaphragm 42 are arranged on the ventilating diaphragm respectively. The bottom and side ends of sheet 4.

The working process of the utility model: the medicine mist released by the aerosol inhaler (MDI) 6 passes through the inhaler insertion port 31 of the rear end cover 3 of the mist storage tank, sprays the medicine mist into the cavity of the mist storage tank body 1, The medicine mist sprayed in front can squeeze part of the air at the rear end of the inner chamber of the mist storage tank body 1 through the vent 32, and can get rid of excess air in the tank body. Since the inner cavity of the mist storage tank body 1 has a certain space, after the pressure is balanced, the medicine mist will not overflow from the air vent 32. When the patient inhales treatment, under the inhalation pressure, the inspiratory one-way diaphragm 41 at the bottom of the ventilation diaphragm 4 of the spacer is opened, as shown in Figure 4, the medicine mist in the inner cavity of the spacer passes through The gap between the inhalation one-way diaphragm 41 and the spacer enters the mask 5 and is inhaled by the patient.
