Combination spirometer-inhaler
Various spirometer-inhaler systems and devices are disclosed. The spirometer-inhaler system may estimate physiological parameters of a user based on the user's inhaled and/or exhaled breaths received by the spirometer-inhaler device. The spirometer-inhaler device may comprise one or more flow paths. A first flow path may direct medication from a medicine canister to an opening of the device. A second flow path may direct a user's exhaled breath from the opening of the device to one or more flow measurement devices.
1. A system for delivering a medication to a user and measuring one or more physiological parameters of the user, the system comprising:
a spirometer-inhaler device comprising:
a first portion configured to removably receive a medicine canister;
a second portion extending from the first portion, the second portion comprising a mouthpiece, wherein the mouthpiece comprises an opening and a plurality of propellors;
a first flow path configured to direct a medication from the medicine canister to the opening of the mouthpiece, wherein the first flow path comprises a first propellor of the plurality of propellors adjacent the opening; and
a second flow path configured to direct exhaled air from the opening of the mouthpiece to one or more flow rate measurement devices, wherein the second flow path comprises a second propellor of the plurality of propellors adjacent the opening;
the medication canister configured to deliver the medication to the first portion of the spirometer-inhaler device; and
one or more measurement devices configured to estimate one or more physiological parameters of the user, the one or more measurement devices comprising the one or more flow rate measurement devices.
2. The system of claim 1 , wherein the spirometer-inhaler device further comprises a central hole configured to removably receive the medicine canister.
3. The system of claim 2 , wherein the spirometer-inhaler device further comprises a one way valve configured to removably connect to the medicine canister and to direct the medication from the medicine canister to the opening of the mouthpiece.
4. The system of claim 3 , wherein the medicine canister is configured to deliver the medication to the one way valve.
5. The system of claim 3 , wherein the first flow path comprises the one way valve and the opening of the mouthpiece.
6. The system of claim 2 , wherein the central hole comprises an internal gap configured to direct the medication from the medicine canister to the opening of the mouthpiece.
7. The system of claim 1 , wherein the spirometer-inhaler device further comprises an interior flow pathway with a first end and a second end.
8. The system of claim 7 , wherein the first end of the interior flow pathway is located adjacent the opening of the mouthpiece, wherein the second end of the interior flow pathway is located on a side portion of the first portion.
9. The system of claim 8 , wherein the second flow path comprises the interior flow pathway and the opening of the mouthpiece.
10. The system of claim 9 , wherein the second end of the interior flow pathway is configured to be connectable to the one or more flow rate measurement devices.
11. The system of claim 7 , wherein the interior flow pathway includes one or more of: one or more interior tubes or one or more interior ribs.
12. The system of claim 1 , wherein the one or more flow rate measurement devices are configured to estimate at least one of: forced inspiratory flow, forced expiratory volume, forced expiratory flow, forced vital capacity, maximal voluntary ventilation, inspiratory reserve volume, expiratory reserve volume, residual volume, functional residual capacity, total lung capacity, inspiratory capacity, tidal volume, vital capacity, maximal inspiratory pressure, or maximal expiratory pressure.
13. The system of claim 1 , wherein the one or more flow rate measurement devices are configured to be connectable to the second flow path.
14. The system of claim 1 , wherein the one or more measurement devices are configured to measure at least one of: oxygen saturation, respiratory rate, total hemoglobin level, level of carboxyhemoglobin, level of methemoglobin, pulse rate, or acoustic measurements.
15. The system of claim 1 , further comprising a display.
16. The system of claim 15 , wherein the display is disposed on one or more of: the spirometer-inhaler device, the one or more measurement devices, or one or more user devices.
17. The system of claim 1 , further comprising a transmitter.
18. The spirometer-inhaler device of claim 17 wherein the transmitter is configured to transmit the one or more physiological parameters of the user to one or more of: a network, a backend system, or one or more user devices.
