Description

Medicine jet atomization inhalation device with reversing valve

Technical Field

The utility model relates to a medical instrument for respiratory disease's aerosol inhalation treatment can prevent effectively that a large amount of vaporific medicines from leaking into the surrounding air environment in the use, avoids the medicine extravagant and polluted environment air.

Background

The aerosol therapy is a common method for treating acute and chronic respiratory diseases of adults and children at present, and is generally applied to the treatment of various respiratory diseases such as acute episode of bronchial asthma, acute episode of chronic obstructive pulmonary disease, bronchiectasis and the like. Compared with systemic administration, aerosol inhalation has the following advantages: 1) the concentration of the local medicine in the airway is high, and the effect is strong; 2) the medicine directly acts on airway epithelial cells, and has quick effect; 3) the dosage of the medicine absorbed into the blood circulation is extremely small, and the side effect of the whole body is small; 4) compared with oral administration, the medicine is not metabolized by the liver, and the first pass effect does not exist; 5) the preparation and application of the medicine are convenient. Thus, aerosol therapy is very widely used.

The current common atomization treatment methods include three methods, namely jet atomization, ultrasonic atomization and vibration sieve mesh atomization. The three atomization modes enable the medicine solution to form aerosol by different means. Jet nebulization is the most widely used form of nebulized inhalation therapy. The jet atomization is driven by high-pressure air or oxygen. The high velocity gas stream passes through the atomizer to convert the drug solution into tiny drug droplets.

As shown in fig. 1 and 2, in the aerosol treatment, a drug solution 10 is placed in an atomizer 11, and when a high-speed airflow 12 passes through a central narrow tube 13 of the atomizer 11, the drug solution is sucked to a tube port by the venturi effect, and the sucked drug solution strikes an upper partition plate 15 and is collided into droplets by the high-speed airflow, thereby forming a drug mist 14. As shown in fig. 3, the large-particle chemical liquid falls down, and the small-particle chemical liquid is sprayed outward in the form of a mist. The medicine mist 14 reaches the mouth of the patient through a T-shaped pipe connected with an opening at the upper end of the atomizer, passes through a mouth piece or a face mask, and enters the air passage to play a therapeutic role when the patient inhales.

The generation of the drug mist is a continuous process in the whole process, and the patient inhales and exhales alternately. When the patient inhales, the medicinal mist can be inhaled into the air passage to play a therapeutic role. When the patient exhales, the drug mist cannot enter the airway, but diffuses into the surrounding atmosphere along with the expiratory airflow. This aspect results in loss and waste of medication, necessitating increased therapeutic drug doses; on the other hand, the drug diffusing into the atmosphere causes air pollution. The polluted air contacts the eyes of the patient and other parts to cause adverse reactions such as mucosa stimulation, increased intraocular pressure, blurred vision and the like; inhalation of contaminated air by surrounding healthy persons can also cause many undesirable consequences such as irritation of the cardiovascular system, the respiratory system, and the like.
