Embodiment 1

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

[0071] An inhalant device that facilitates the inhalation of inhalants into the depths of the lungs, comprising a housing 1, and the housing 1 is provided with a storage portion for placing a medicine storage tank 2 and an inhalation portion 3 for patients to inhale the medicine. The inhaler device further 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 opening 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. In this way, the medicine can be inhaled quickly, so that the medicine can enter the deep lungs and ensure a good treatment. effect, as well as...

Embodiment 2

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

[0087] An inhalant device that facilitates the entry of inhalants deep into the lungs, on the basis of any method in Embodiment 1, further, the threshold switch 4 is an elastic elastic baffle 11 provided in the cylinder 5 When the negative pressure in the medicine chamber 7 reaches the threshold value of the threshold switch 4 , the deformation of the elastic blocking piece 11 ensures that the sliding member 9 can move toward the opening of the suction part 3 through the elastic piece. In this solution, the elastic coefficient of the elastic member is matched with the set threshold value to ensure that the patient inhales, so that when the negative pressure in the medicine chamber 7 reaches the threshold value, the sliding member 9 can smoothly pass through the elastic sheet and move towards the inhalation part 3 direction. medicine.

Embodiment 3

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

[0089] An inhalant device that facilitates the entry of inhalants deep into the lungs, on the basis of any method in Embodiment 1, further, the threshold switch 4 includes a blocking member 12 and a spring 13, 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 set between the groove 14 and the blocking member 12, and the side of the blocking member 12 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 cylindrical body 5 , which forms a blocking for the sliding member 9 at this time. The elastic coefficient of the spring 13 matches the set threshold value to ensure that the patient inhales, and when the negative pressure in the medicine chamber 7 reaches the threshold value, the pressure exerted by the sliding member 9 on the blocking memb...

Abstract

The present invention relates to the field of inhalant devices, in particular, to an inhalant device that facilitates inhalation of inhalants into the deep lungs, comprising a casing, on which is provided a storage portion for placing a medicine storage tank and a patient The inhalation part for inhaling the medicament, the inhalation device also includes a threshold switch, the threshold switch has a braking state and an open state, and the threshold value of the threshold switch matches the negative pressure value generated in the inhalation part when the patient inhales the inhalation part, when the threshold value switch When it is in the braking state, the medicine is blocked, so that the patient cannot inhale the medicine at the inhalation part; when the negative pressure value generated by the patient's inhalation at the inhalation part is equal to or greater than the threshold value, the threshold switch changes from the braking state to the open state, And keep the open state, so that the patient can inhale the medicine through the inhalation part. In the scheme of the present application, the medicament can enter the lungs at a relatively high flow rate, which can achieve a good drug supply effect and treatment effect, and greatly reduce the risk of adverse drug reactions.

Description

technical field [0001] The present invention relates to the field of inhaler devices, in particular, to an inhaler device that facilitates inhalants entering deep into the 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, fast onset, and few systemic adverse reactions. [0003] At present, the more common inhalation device is a pressurized metered dose inhaler, which mainly includes a shell, a suction nozzle, a medicine storage tank, and a medicine spray tube. When the medicine storage tank is pressed down, a certain amount of aerosol is sprayed, and the aerosol enters the medicine cavity of the shell through the spray port on the spray tube. The aerosol in the cavity is inhaled to reach the lungs, thus realizing the supply of medicine to the lungs. After the inhalation is completed, gargle again, and spit out the...
