Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-6, a drug delivery device for department of respiration, comprises a housing 1, the housing 1 comprises a top cover 2 and a base 3, a capsule base 4 is arranged inside the base 3, a suction nozzle 5 is movably connected to the top of the capsule base 4, the capsule base 4 is used for placing a capsule, a puncturing device 6 is arranged on the base 3, the puncturing device 6 penetrates through the capsule base 4 and is used for puncturing the capsule, a gas flow rate detection device 7 is arranged inside the suction nozzle 5, and the gas flow rate detection device 7 is used for detecting the gas flow rate generated by the oral cavity in the suction nozzle 5 and controlling the opening and closing of the suction nozzle 5.

In further detail, the puncturing device 6 comprises a needle 8 and a button 9, the button 9 is connected with the base 3 through a spring, the spring is installed inside the base 3 and used for resetting the button 9, the button 9 is fixedly connected with the needle 8, and the needle 8 penetrates through the capsule base 4. In this setting, when the capsule is put into capsule base 4, push button 9 is extruded with strength, and button 9 drives syringe needle 8 and punctures the capsule, then loosens the hand, and the spring can make button 9 reset, the puncture of the next time of being convenient for.

In more detail, there are at least two needles 8. In the arrangement, the two needles 8 stimulate the capsule under the driving of the button 9, and the puncture area of the two needles 8 to the capsule is increased, so that the granular medicine in the capsule is sucked out more easily.

In further detail, the gas flow rate detection device 7 comprises a fan blade 10, a control module 11 and an electric valve 12, the fan blade 10 rotates when receiving the suction force of a user, the control module 11 is used for controlling the opening and closing of the electric valve 12, the electric valve 12 is a two-position two-way electromagnetic valve, a connecting port 18 is arranged at the bottom of the electric valve 12, the connecting port 18 is used for being connected with the capsule base 4, a buzzer 19 is further arranged on the suction nozzle 5, and the buzzer 19 is electrically connected with the control module 11. In this setting, the user aims at suction nozzle 5 with the mouth and breathes in, then the inside air current that forms of suction nozzle 5, this air current can drive fan blade 10 and rotate, reach the settlement within range when the rotational speed of fan blade 10, control module 11 control electric valve 12 circular telegram, thereby passageway among the electric valve 12 is opened and bee calling organ 19 sends the suggestion user's medicine of making a sound and is being inhaled, the mode of dosing is more scientific, the treatment effect has the improvement that is showing, when the fan blade rotational speed is not presetting the within range, the effect of dosing is poor, control module 11 closes electric valve 12 and bee calling organ 19 and can not send the sound, last connector 18 can cup joint together with capsule base 4, the leakproofness increases, the medicine effect is better and the capsule is difficult to wet.

In further detail, a cavity 13 is arranged on the axis of the capsule base 4, and the cavity 13 is used for placing the capsule. In this setting, cavity 13 in capsule base 4 just can be used for placing the capsule for the capsule is fixed, thereby is punctured by piercing device 6, and wherein cavity 13 space is less, just can hold a capsule, makes it easier when the patient inhales the capsule granule.

In further detail, the top of the capsule base 4 is provided with a sealing gasket 14. In this setting, capsule base 4 embedding is inside base 3, and the top links together through seal gasket 14 and suction nozzle 5, and seal gasket 14 can make the leakproofness between suction nozzle 5 and the capsule base 4 better for when the patient advances medicine through suction nozzle 5, the condition of gas leakage can not appear, has guaranteed the stability of advancing medicine.

In further detail, the inner wall of the base 3 is provided with a ring 15, and the ring 15 is used for clamping the capsule base 4. In this setting, capsule base 4 can be taken out from base 3, the follow-up thorough clearance to base 3 of being convenient for, and ring 15 can carry out the screens to capsule base 4 simultaneously for capsule base 4 erects on base 3.

More specifically, the bottom surface of the base 3 is a parallel surface. Base 3 ground becomes the parallel plane in this setting, and this is the placing that makes things convenient for shell 1 can steadily place.

To elaborate, the top cover 2 is provided with a recess 16. In this arrangement, when the top cover 2 is opened, the top cover 2 is not convenient to open because the surface of the top cover 2 is smooth, and in order to avoid this situation, the notch 16 is grasped by hand, so that the notch 16 is used as an acting point to open the top cover 2, and meanwhile, the corners of the notch 16 are arc-shaped corners to avoid injury to the skin of a patient.

In further detail, the bottom of the top cover 2 is provided with a sealing gasket 17. In this setting, when top cap 2 and base 3 lock joint are in the same place, the gap between leads to the inside humidity of base 3 easily, breeds the bacterium, in order to avoid this kind of condition, sets up seal ring 17 in the bottom of top cap 2, and seal ring 17 can fill the gap between top cap 2 and the base 3, has guaranteed the inside drying of base 3.
