experiment example 1

[0080] Negative pressure is formed in the mist control chamber 100 by using the negative pressure generating component 500 . To study the relationship between the distance between the air inlet 150 and the fixed port 110 and the amount of medicine collected by the adsorption assembly 300, a breathing simulator was used to simulate the patient's nebulization inhalation process (the experiment was repeated 3 times). The experimental results are shown in Table 1.

[0081] Table 1 The relationship between the distance between the air inlet and the fixed inlet and the collected charge

[0082]

[0083] During the above experiment process, the load voltage of the negative pressure generating component 500 was turned on to the maximum. It can be seen from Table 1 that when the distance between the air inlet 150 and the fixed port 110 is 33 mm, the amount of drug collected by the adsorption assembly 300 is significantly larger than that when the distance between the air inlet 150 a...

experiment example 2

[0087] The mist-controlled inhalation device installed with the air inlet 150 should be able to ensure that the normal process of intercepting and absorbing the drug particles exhaled by the patient will not affect the treatment process of the patient's normal nebulized inhalation of the drug solution. Next, a comparison was made between the mist control inhalation device with different opening positions of the air inlet 150 and the situation of directly using the nebulizer cup for nebulization inhalation treatment (the experiment was repeated 3 times), and the experimental results are shown in Table 2.

[0089]

[0090]

[0091] It can be seen from Table 2 that when the distance between the air inlet 150 and the fixed port 110 is 33 mm or 15 mm, the delivered dose (drug dose delivered into the lungs of the patient) of the two i...

Abstract

The invention relates to a fog control inhalation device. The fog control inhalation device comprises a fog control chamber, an atomization assembly, an adsorption assembly, a communication assembly and a negative pressure generation assembly, wherein a fixed opening and a connection opening are formed in the fog control chamber; the atomization assembly is arranged in the fog control chamber; theatomization assembly comprises a suction nozzle and an inhalation drug channel positioned on the suction nozzle; the suction nozzle is arranged at the fixed opening; the atomization assembly can be used for atomizing a medicine solution and outputting liquid drops formed by atomization to the outer part of the fog control chamber through the suction nozzle; the adsorption assembly is arranged inthe fog control chamber and is used for adsorbing drug particles in inhalation gas which is inhaled into the fog control chamber through the inhalation drug channel; one end of the communication assembly is connected with the connection opening; the negative pressure generation assembly is connected with the other end of the communication assembly; and the negative pressure generation assembly canbe used for driving the inhalation gas in the fog control chamber to flow out from the communication assembly, so that negative pressure is formed in the fog control chamber. A patient can hold the fog control chamber to inhale drugs, so that the convenience and comfort of utilization are improved; the amount of the drugs exhaled by the patient and the dosage of effective drugs which actually enter the body of the patient can be counted and known.

Description

technical field [0001] The invention relates to the field of nebulized inhalation treatment, in particular to a mist-controlled inhalation device. Background technique [0002] Inhalation administration refers to a method of administration in which aerosol drugs are inhaled from the respiratory tract. After the drug is inhaled, it reaches the alveoli through the trachea and bronchi. Due to the large surface area of ​​the alveoli (about 60m 2 ), rich pulmonary capillaries, rapid blood circulation and high permeability of alveolar epithelial cells, etc., make the drug very easy to diffuse and absorb into the blood. [0003] Among the many methods of inhalation administration, nebulization inhalation is the method currently used in many hospitals (because this inhalation administration method does not require additional training for patients). However, in the actual operation process, in addition to being inhaled by the patient, the drug particles delivered by atomization wil...
