Problems solved by technology

[0008] The object of the present invention is to provide an inhalant that can make the inhalant enter the deep lung of the patient, aiming at the problem that the inhalant cannot enter the deep lung due to the light inhalation of the patient in the current use of the inhalant device, which leads to poor therapeutic effect. place, thereby achieving good therapeutic effect and reducing the use of inhalant devices for adverse reactions

Embodiment 1

[0067] Example 1, as Figure 1-3 shown,

[0068] An inhalation force adjustable inhaler device, comprising an inhalation part 3 for a patient to inhale a medicament, and 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 the same as that of the patient. The threshold value of the threshold switch 4 can be adjusted to match the negative pressure value generated in the suction part 3 when the suction part 3 inhales.

[0069] In this solution, the threshold switch 4 is used to prevent inhalation of the drug. When the patient's negative inspiratory pressure reaches the threshold value of the threshold switch 4, the threshold switch 4 is turned on and the patient can inhale the drug. Moreover, the threshold size of the threshold switch 4 can be adjusted. For patients with healthy or better lung capacity, the threshold value of threshold switch 4 can be appropriately increased, so that the inhaled...

Embodiment 2

[0077] Example 2, as Figure 1-3 shown,

[0078] A suction strength adjustable inhaler device, on the basis of Embodiment 1, a sliding member 9 is slidably arranged in the cylinder body 1, and the sliding member 9 and the side wall of the cylinder body 1 are clearance fit. or a sealed fit,

[0079] The threshold switch 4 is used to control the sliding of the sliding member 9 along the cylindrical body 1. When the negative pressure between the sliding member 9 and the opening of the suction portion 3 is equal to or greater than the threshold, the threshold switch 4 is controlled by the control. The dynamic state changes to the open state, and the sliding member 9 moves toward the opening of the suction part 3 under the action of the negative pressure.

[0080] In this solution, a sliding member 9 is provided in the cylinder 1, and the threshold switch 4 is used to brake the sliding member 9. In the initial stage of inhalation by the patient, the negative pressure value in the...

Embodiment 3

[0090] Example 3, as Figure 1-6 shown,

[0091] In an inhalation device with adjustable inhalation strength, on the basis of Embodiment 2, an observation window 16 is provided on the cylinder 1 corresponding to the medicament chamber 7, and the observation window 16 is made of a transparent material.

[0092] In the above manner, by using a transparent material, the position change of the sliding member 9 in the medicine chamber 7 can be easily observed, and the situation of the medicine in the medicine chamber 7 being inhaled by the patient can be grasped conveniently.

[0093] As a preferred embodiment, on the basis of the above solution, further, on the cylindrical body 1 , a scale line is further provided along the sliding direction of the sliding member 9 . The setting of the scale line can more accurately know the actual inhalation amount of the medicine.

[0094] As a preferred embodiment, on the basis of the above solution, further, a protrusion 17 is provided on th...

Abstract

The present invention relates to the field of inhalation devices, in particular, to an inhalation device with adjustable inhalation strength, comprising an inhalation part for patients to inhale medicaments, and a threshold switch, wherein the threshold switch has a braking state and an open state , the threshold value of the threshold switch matches the negative pressure value generated in the inhalation part when the patient inhales the inhalation part, and when the threshold value switch is in the braking state, the medicament is blocked, so that the patient cannot have the inhalation part inhaling the medicament; 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 value switch changes from the braking state to the open state, and keeps the open state, so that the patient can inhale the medicine from the inhalation part, the threshold value switch The threshold size is adjustable. The inhalation device of the present application can achieve good drug supply and treatment effects, greatly reduce the risk of adverse drug reactions, and can also be used by patients with different physical conditions.

Description

technical field [0001] The invention relates to the field of inhalation devices, in particular to an inhalation device with adjustable inhalation force. 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 medicine in the oral cavi...
