Description

Medicine jet atomization inhalation device with double-channel T-shaped tube

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 1 is placed in an atomizer 2, and when a high-speed airflow 3 passes through a central narrow tube 4 of the atomizer 2, the drug solution is sucked to a tube port by the venturi effect, and the sucked drug solution strikes a spacer 6 above the tube port and is collided into droplets by the high-speed airflow, thereby forming a drug mist 5. 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 medicinal mist 5 reaches the mouth of the patient through a T-shaped pipe which is connected with the upper end opening of the atomizer and is shown in figure 4, and enters the air passage to play a therapeutic role when the patient inhales through a mouth piece or a face mask.

The conventional T-tube is shown in fig. 4 and comprises a central vertical tube portion 7-1 and a horizontal tube portion 7-2 communicating with the vertical tube portion 7-1. The atomizer is connected with the vertical pipe part 7-1, and medicinal mist is continuously input to the transverse pipe part 7-2 through the vertical pipe part 7-1. One end of the horizontal pipe part 7-2 is a mouthpiece or is connected with a mask, and the other end is communicated with the ambient air. When a patient inhales, air flows in from the other end of the transverse pipe part 7-2, and the inflowing medicine mist carries the medicine mist in the T-shaped pipe to enter the airway of the patient through one end of the transverse pipe part 7-2. When the patient inhales, the medicament can be well inhaled by the patient. However, during patient exhalation, the drug mist will be entrained by the patient's exhaled airflow through the other end of the cross tube portion 7-2 into the ambient air. Therefore, on one hand, the loss and waste of the medicine are caused, and the dosage of the treatment medicine must be increased; on the other hand, the drug diffusing into the atmosphere causes air pollution. The contaminated air can cause adverse reactions such as mucosa irritation, increased intraocular pressure, blurred vision and the like when contacting the eyes and other parts of a patient. 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.
