Referring to fig. 1-4, the present invention provides a technical solution:
a DPI inhalation device training instrument comprises a breathing bottle 1 and a mouth-containing port 10 with a reduced mouth diameter arranged at the top end of the breathing bottle and used for holding inhalation. The bottom end of the breathing bottle 1 is connected with a sealing gasket 2 and a rotating chassis 3 in sequence. An air duct 12 is arranged on one side of the inner wall of the breathing bottle 1, and the inside of the air duct 12 is communicated with the inside of the breathing bottle 1, so that air flow can pass through the air duct 12 during inspiration. A float 13 is inserted into the air duct 12, and the float 13 is made of PP foam, and has a light weight that can rise in the air duct 12 in response to the airflow. The top end of the air duct 12 is in a net structure to prevent the float 13 from being sucked out from the top end. The bottom end of the air duct 12 is higher than the bottom surface of the breathing bottle 1, and air flow is used for entering. The center of the bottom end surface of the breathing bottle 1 is provided with a convex column 16, and the bottom end of the convex column 16 is provided with a limiting platform 17 with enlarged outer diameter. The bottom surface of the breathing bottle 1 is provided with a fan-shaped vent 18. The center of the sealing gasket 2 is sleeved and matched with the convex column 16. The top surface of the sealing gasket 2 is provided with an avoiding opening 20 with the same size as the vent hole 18, so that the airflow enters the breathing bottle 1 through the avoiding opening 20. The equal area distribution of the top surface of rotary chassis 3 has first district 30 of breathing in, the second district 31 and the third district 32 of breathing in, counter bore 33 has been seted up at rotary chassis 3's top surface center, counter bore 33 passes spacing platform 17 and cup joints the cooperation with projection 16, the gross thickness of sealed pad 2 and rotary chassis 3 is greater than the height of projection 16, it does not the slippage to restrict rotary chassis 3 through spacing platform 17, because sealed pad 2 is tightly crowded to rotary chassis 3, it can stop when rotatory in the optional position and do not rock.
In the embodiment, the sealing gasket 2 is made of silica gel, so that the flexibility and the sealing performance are good; the breathing bottle 1 and the rotating chassis 3 are made of PP materials and are integrally formed, and the breathing bottle is light in weight, good in toughness, rigid in strength and not prone to cracking. The lateral surface of the rotary chassis 3 is provided with a plurality of raised strips, so that the friction force of hand contact is increased, and the rotation is facilitated.
Furthermore, an annular mark line 11 is arranged on one side of the breathing bottle 1 close to the bottom of the breathing bottle and used for judging whether the ascending height of the buoy 13 reaches the standard or not, so that the ascending height is higher than the standard so as to indicate that the inspiratory capacity of the patient reaches the standard.
Specifically, one side of the breathing bottle 1 is provided with a scale mark 15, and the range of the scale mark 15 is 0-120L/min, which represents the inspiration volume per minute.
Specifically, the buoy 13 is hemispherical, the bottom end of the buoy is provided with the extension strip 14, the length of the extension strip 14 is greater than the distance between the bottom end of the air duct 12 and the bottom surface of the breathing bottle 1, and when the air is not inhaled, the extension strip 14 can be stably supported on the bottom surface of the breathing bottle 1.
In addition, the sealing gasket 2 is adhered to the bottom surface of the respiration bottle 1, so that the respiration bottle can stably play a sealing role.
It is worth noting that the top surfaces of the first air suction area 30, the second air suction area 31 and the third air suction area 32 are provided with a plurality of air inlet holes with the number increasing in sequence, and the calibers are different. When in air suction, the rotating chassis 3 is rotated to ensure that the first air suction area 30, the second air suction area 31 and the third air suction area 32 are sequentially aligned with the air vent 18, so that the training of the air suction flow rate of the register, the tiotropium bromide and the three inhalants can be realized.
It is added that the external diameters of the sealing gasket 2 and the rotating chassis 3 are the same as the external diameter of the breathing bottle 1, so that the overall matching is beautiful.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
