Inhalation systems, breathing apparatuses, and methods
Examples of the invention include inhalation systems, breathing apparatuses, and methods for administering a solution by inhalation to a patient. Example breathing apparatuses described herein may be configured to minimize loss of the solution to the environment. Additionally or instead, example breathing apparatuses may be configured to recirculate exhaled solution to increase an amount of the solution available to a patient while minimizing exhausted solution. In some examples, breathing apparatuses may deliver nebulized platelet rich plasma (“PRP”).
1. A method for treating a respiratory disorder by inhalation using a breathing apparatus, the method comprising:
providing a platelet rich plasma in a liquid solution;
aerosolizing the liquid solution of platelet rich plasma using a sterile nebulizer; and
providing the aerosolized platelet rich plasma solution to a patient through a breathing apparatus coupled to the nebulizer,
wherein the sterile nebulizer is connected to a first end of a rebreathing chamber of the breathing apparatus,
wherein an exhaust tube of the breathing apparatus is connected to a second, opposite end of the rebreathing chamber,
wherein a cleaning unit is connected to a distal end of the exhaust tube, and
wherein the exhaust tube and cleaning unit are configured to permit flow in both directions, both within the exhaust tube and through the cleaning unit.
2. The method of claim 1 , wherein said providing the aerosolized platelet rich plasma solution to the patient includes providing the aerosolized platelet rich plasma solution to the patient through a breathing mask of the breathing apparatus connected to the nebulizer and to the first end of the rebreathing chamber, and wherein the method further comprises:
receiving exhaled platelet rich plasma solution in the rebreathing chamber; and
providing at least a portion of the exhaled platelet rich plasma solution to the patient through the breathing mask.
3. The method of claim 2 , further comprising storing fresh platelet rich plasma solution in the breathing apparatus during an exhalation, and providing the stored platelet rich plasma solution to the patient in a subsequent inhalation.
4. The method of claim 2 , wherein the portion of the exhaled platelet rich plasma solution provided to the patient through the breathing mask is recycled air when exhaled by the patient.
5. The method of claim 4 , further comprising receiving at least a portion of the recycled air and providing the recycled air to an outlet for discharge via the exhaust tube.
6. The method of claim 5 , further comprising filtering the recycled air through the cleaning unit prior to discharge.
7. The method of claim 6 , wherein the filtering is performed by an ultraviolet light source.
8. The method of claim 6 , wherein the filtering is performed by a High-Efficiency Particulate Filter (HEPA).
9. The method of claim 6 , wherein the filtering is performed by a heating coil with a fan.
10. The method of claim 1 , further comprising inducing turbulent flow in the rebreathing chamber.
11. The method of claim 1 , further comprising identifying a respiratory disorder in the patient.
12. The method of claim 1 further comprising:
drawing blood from the patient, wherein the platelet rich plasma solution is derived from the blood of the patient.
13. The method of claim 12 , further comprising injecting the platelet rich plasma solution into a sterile port of the nebulizer.
14. The method of claim 12 further comprising:
mixing the blood with an anticoagulant;
centrifuging the blood and anticoagulant to form a layered solution including the platelet rich plasma solution; and
collecting the platelet rich plasma solution from the layered solution, wherein the platelet rich plasma solution is a layer between a red blood cell rich layer and a plasma layer.
15. The method of claim 1 , wherein providing the aerosolized platelet rich plasma solution to a patient comprises providing an amount sufficient to treat a respiratory disorder, wherein the amount sufficient to treat the respiratory disorder is about 6 to about 9 cubic centimeters of the platelet rich plasma solution.
16. The method of claim 1 , wherein the respiratory disorder is a chronic obstructive pulmonary disorder, a bacterial or viral lung infection, a damage to lungs from smoking, an endstage respiratory disorder, a seasonal allergy, sinusitis, pleuritic chest pain, ischemic cardiac pain, or combinations thereof.
17. The method of claim 1 , where in the platelet rich plasma is diluted in a platelet poor plasma solution.
18. The method of claim 1 , further comprising providing a platelet poor plasma solution to the patient after providing the platelet rich plasma solution.
19. The method of claim 1 , further comprising activating the platelet rich plasma solution to initiate production of growth hormones.
20. A method for treating a respiratory disorder by inhalation using a breathing apparatus, the method comprising:
providing a platelet rich plasma in a liquid solution;
aerosolizing the liquid solution of platelet rich plasma using a sterile nebulizer; and
providing the aerosolized platelet rich plasma solution to a patient through a breathing apparatus coupled to the nebulizer,
wherein the sterile nebulizer is connected to a first end of a rebreathing chamber of the breathing apparatus, and
wherein an exhaust tube of the breathing apparatus is connected to a second, opposite end of the rebreathing chamber and a cleaning unit is connected to a distal end of the exhaust tube, and the exhaust tube and cleaning unit are configured to permit flow in both directions, both within the exhaust tube and through the cleaning unit.
