Embodiment 1

[0070] Example 1, such as Figure 1-8 as shown,

[0071] An inhalant device that facilitates the inhalation of inhalants into the deep lungs, comprising a casing 1, on which a storage portion for placing a drug storage tank 2 and an inhalation portion 3 for a patient to inhale the medicament are arranged. The inhalant device also includes a threshold switch 4, the threshold switch 4 has a braking state and an open state, and the threshold value of the threshold switch 4 is related to the negative pressure value generated in the inhalation part 3 when the patient inhales the inhalation part 3. match. Through the difference between the braking state and the open state of the threshold switch 4, the medicine can be inhaled only when the negative pressure generated by the patient’s inhalation reaches a certain value, so that the medicine can be inhaled quickly, and then the medicine can enter deep into the lungs to ensure good treatment. effect, as well as reducing the side effe...

Embodiment 2

[0086] Example 2, such as image 3 and 4 as shown,

[0087] An inhalant device that facilitates the inhalant to enter deep into the lungs. On the basis of any method in Embodiment 1, further, the threshold switch 4 is an elastic elastic baffle 11 arranged in the cylinder 5 , when the negative pressure in the medicine chamber 7 reaches the threshold of the threshold switch 4 , the deformation of the elastic flap 11 ensures that the sliding member 9 can move towards the opening of the inhalation part 3 through the elastic flap. In this solution, the elastic coefficient of the elastic piece is matched with the set threshold to ensure that the patient inhales, so that when the negative pressure in the medicine chamber 7 reaches the threshold, the sliding part 9 can smoothly move towards the inhalation part 3 through the elastic piece. supply medicine.

Embodiment 3

[0088] Example 3, such as figure 1 and 2 as shown,

[0089] An inhalant device that facilitates the inhalant to enter the deep lung. On the basis of any method in Embodiment 1, further, the threshold switch 4 includes a blocking member 12 and a spring 13, and on the inner wall of the barrel 5 A groove 14 is provided, the blocking member 12 is set in the groove 14, the spring 13 is arranged between the groove 14 and the blocking member 12, and the side of the blocking member 12 facing away from the suction part 3 is slope. In this way, when the blocking member 12 is not under pressure, a part of the blocking member 12 protrudes from the inner wall of the cylinder 5, and at this time forms a block to the sliding part 9. In this solution, the The elastic coefficient of the spring 13 matches the set threshold to ensure that the patient inhales, so that when the negative pressure in the medicine chamber 7 reaches the threshold, the pressure exerted by the sliding part 9 on the b...

Abstract

The invention relates to the field of inhalant devices, in particular to an inhalant device favorable for inhalant to enter deep part of lung. The device comprises a shell, the shell is provided witha storage part used for containing a medicine storage tank and an inhalation part used for inhaling medicine by a patient. The inhalant device further comprises a threshold switch, the threshold switch has a braking state and an opening state, the threshold value of the threshold switch is matched with the value of negative pressure generated in the inhalation part when the patient inhales from the inhalation part, and when the threshold switch is in the braking state, the medicine is stopped, so that the patient cannot inhale the medicine through the inhalation part; and when the value of thenegative pressure generated when the patient inhales from the inhalation part is equal to or larger than the threshold value, the threshold value switch is changed from the braking state to the opening state and kept in the opening state, and the patient can inhale the medicine from the inhalation part. In the scheme of the invention, the medicine can enter the lung at a relatively high flow rate, so that a good medicine supply effect and a good treatment effect can be achieved, and the adverse reaction risk of medicament use is greatly reduced.

Description

technical field [0001] The invention relates to the field of inhalant devices, in particular to an inhalant device that facilitates the inhalation of inhalants into deep lungs. Background technique [0002] Inhalation is used in the treatment of respiratory diseases. Inhalation therapy can make the drug directly act on the respiratory tract and lungs, with direct curative effect, quick onset, and few systemic adverse reactions. [0003] The more common inhalant device at present is a pressurized metered-dose inhaler, which mainly includes a casing, a suction nozzle, a drug storage tank, and a spray tube. , press down on the medicine storage tank to spray a certain amount of aerosol, and the aerosol enters the medicine cavity of the shell through the medicine spraying port on the medicine spray tube. The aerosol in the cavity is inhaled and reaches the lungs, so that the lungs can be supplied with medicine. After the inhalation is completed, rinse the mouth and spit out the ...
