Embodiment 1

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

[0068] An inhalation device with adjustable inhalation force, which includes an inhalation part 3 for patients to inhale medicine, and also includes a threshold switch 4, the threshold switch 4 has a brake state and an open state, and the threshold of the threshold switch 4 is the same as that of the patient. The value of the negative pressure generated in the suction part 3 matches the value of the negative pressure generated in the suction part 3 when the suction part 3 inhales, and the threshold value of the threshold switch 4 is adjustable.

[0069] In this scheme, the threshold switch 4 is used to prevent the inhalation agent. When the patient's inspiratory negative pressure reaches the threshold value of the threshold switch 4, the threshold switch 4 is opened, and the patient can inhale the medicine. Moreover, the threshold value of the threshold switch 4 can be adjusted. Adjustment, for healthy patients with normal or ...

Embodiment 2

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

[0078] An inhalation device with adjustable inhalation force. On the basis of Embodiment 1, a sliding part 9 is slidably arranged in the cylinder body 1, and the sliding part 9 and the side wall of the cylinder body 1 are clearance fit or seal fit,

[0079] The threshold switch 4 is used to control the sliding of the sliding part 9 along the inside of the barrel 1. When the negative pressure between the sliding part 9 and the opening of the suction part 3 is equal to or greater than the threshold, the threshold switch 4 is controlled by the control. The dynamic state is transformed into 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 part 9 is set in the cylinder 1, and the threshold switch 4 is used to brake the sliding part 9. At the initial stage of the patient's inhalation, the negative pressure in the c...

Embodiment 3

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

[0091] An inhalation device with adjustable inhalation force, based on the second embodiment, is provided with an observation window 16 on the cylinder body 1 corresponding to the medicine chamber 7, and the observation window 16 is made of a transparent material.

[0092] In the above manner, by using transparent materials, it is possible to conveniently observe the position change of the sliding member 9 in the medicine chamber 7 and then grasp the situation of the medicine in the medicine chamber 7 being inhaled by the patient.

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

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

Abstract

The invention relates to the field of inhalant devices, in particular to an inhalant device with adjustable inhalation force. The device comprises an inhalation part for inhaling a medicament by a patient, and further comprises a threshold switch with a braking state and an opening state; a threshold of the threshold switch is matched with the value of negative pressure generated in the inhalationpart when the patient inhales air by the inhalation part, and when the threshold switch is in the braking state, the medicament is stopped, so that the patient cannot inhale the medicament by the inhalation part; when the value of the negative pressure generated when the patient inhales the air by the inhalation part is equal to or larger than the threshold, the threshold switch is converted to be in the opening state from the braking state and kept in the opening state, so that the patient can inhale the medicament by the inhalation part; and the threshold of the threshold switch is adjustable. According to the inhalant device, the good medicine supply effect and the good treatment effect can be achieved, the adverse reaction risk of medicine use is greatly reduced, and the inhalant device can be suitable for 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, 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 medicine in the mouth. ...
