Description

Special drainage suction nozzle for handheld micro-screen atomizer

Technical Field

The utility model belongs to medicine atomization device field, concretely relates to dedicated drainage suction nozzle of hand-held type microgrid atomizer.

Background

At present, the medicines for inhalation preparations are mainly administered to patients through a pressurized Metered Dose Inhaler (MDI), a Dry Powder Inhaler (DPI) and an atomizer, wherein the aerosol inhalation therapy of the atomizer is a method of dispersing a liquid medicine into fine droplet particles by using an atomizing device, spraying the fine droplet particles in an aerosol form, suspending the medicine in air, and inhaling the medicine into a respiratory tract and a lung through the nose or mouth to achieve the purpose of treating various diseases, and the method also gradually becomes an effective treatment means for systemic administration and is widely used in clinic. The atomization treatment is the first choice treatment method for acute attack of bronchial asthma because the atomization treatment can take effect quickly and does not need active cooperation of patients.

When administering a drug by inhalation, nebulizers are generally equipped with an inhalation aid such as a mouthpiece or a face mask to ensure that the nebulized gas can sufficiently enter the respiratory tract. One end of the existing inhalator such as a mask or a suction nozzle is connected with the air outlet hole of the atomizer, the other end of the existing inhalator is directly butted with the mouth and the nose of a patient, and air directly enters the respiratory tract of the patient from the air outlet hole of the atomizer through the cavity of the mask or the suction nozzle. At the moment, the pressure of the gas in the cavity of the breathing mask or the suction nozzle is often different from the normal atmospheric pressure, so that the patient can not adapt to the gas pressure and flow velocity well, the smooth breathing and even unsmooth breathing of the patient are influenced, the gas backflow is caused, the atomized gas is not fully utilized, and the atomization effect is influenced.

Aiming at the problems, the opening is arranged on the suction nozzle (mouthpiece) or the face mask, so that the gas sprayed by the atomizer can be mixed with the air in time to form liquid drop mixed gas which is suitable for the patient to inhale and has the same pressure as the atmospheric pressure. The device is beneficial to fully utilizing the atomizing gas and improving the atomizing effect, thereby improving the overall efficiency of the atomizing inhalation drug delivery system.

However, the respiratory volumes required by different patients are different, and if the hole is too large, the medicine can leak out, so that the treatment effect is poor; if the holes are too small, the inhalation amount is insufficient, and the treatment comfort is greatly reduced.
