- FIG. 3 is a simplified pictorial illustration of the inexuflator of FIG. 1 in a second orientation comprising exuflation of the patient, in accordance with a preferred embodiment of the present invention.
- Reference is now made to FIGS. 1 and 2, which illustrate an
inexuflator 10 constructed and operative in accordance with a preferred embodiment of the present invention. -
Inexuflator 10 preferably includes a patient interface unit 12 (FIG. 2), which may comprise without limitation, a facemask applied to a patient's face or alternatively a tube connector that connects directly to a tracheotomy cannula (not shown), for example. Asource 14 of negative fluid pressure may be provided, such as but not limited to, a vacuum cleaner or any other suitable suction device, such as a standard medical suction unit. Asource 16 of positive fluid pressure may be provided, such as but not limited to, an “AMBU” type manual resuscitator bag or a mechanical ventilator, for example. It is noted that thesources - A
manual valve 18 is preferably connected to thesource 14 of negative fluid pressure and to thesource 16 of positive fluid pressure. Valve 18 is adapted to selectively connectpatient interface unit 12 withsources - The following is one example of a construction of
manual valve 18, although it is understood that themanual valve 18 is not limited to this construction. In the illustrated embodiment,manual valve 18 comprises acylindrical housing 20 having aconnector element 22 for connection topatient interface unit 12 and anotherconnector element 24 for connection to thesource 14 of negative fluid pressure. Anaperture control device 26 may be provided at the interface betweenhousing 20 andconnector element 24 for varying the amount of negative pressure, i.e., controlling the amount of suction.Housing 20 may have anopening 27 that fluidly communicates withconnector element 24. One ormore pressure sensors 28 may be provided for sensing the positive fluid pressure or the negative fluid pressure, such as but not limited to, a Pitot tube or a manometer on housing 20 (pressure sensor 28 is omitted for clarity in FIGS. 2 and 3). -
Manual valve 18 may comprise asliding element 30 that may include a hollowcylindrical piston 32 that slides inhousing 20. Piston 32 may have anaperture 34 formed therein adapted to be selectively in fluid communication with opening 27 ofhousing 20, as described more in detail hereinbelow. A sealingelement 36 may be provided that is in selectively sealed engagement withpiston 32 of slidingelement 30.Sealing element 36 may comprise a hollow cylinder with atapered end 38. Taperedend 38 may be formed with a plurality ofopenings 40 through which a fluid, such as air, may pass. Aseal 42, such as an O-ring, may be placed attapered end 38 proximal (i.e., closer to the connector element 22) to openings 40.Sealing element 36 may be coupled topiston 32, without limitation, by means of a tongue 44 that protrudes from a proximal end of sealingelement 36 and which is received inaperture 34. Tongue 44 is adapted to pullpiston 32 whenpiston 32 is manually moved out ofhousing 20 by an operator ofinexuflator 10, andseal 42 is adapted to pushpiston 32 whenpiston 32 is moved intohousing 20 by the operator ofinexuflator 10. Ascrew 48 may optionally protrude into agroove 46 on the outer surface ofpiston 32 and serve as a stop to limit the travel ofpiston 32 inhousing 20. -
Sliding element 30 comprises a first orientation and a second orientation. In the first orientation, shown in FIG. 2,sealing element 36 does not abut againstpiston 32 and fluid may flow from thesource 16 of positive fluid pressure topatient interface unit 12. However,aperture 34 is not aligned with opening 27 ofhousing 20 and thus slidingelement 30 substantially seals fluid flow from thesource 14 of negative fluid pressure topatient interface unit 12. - In the second orientation, shown in FIG. 3,
sliding element 30 has been moved generally in the direction of an arrow 50 (towards theconnector element 22 that connects to patient interface unit 12). In the second orientation,seal 42 ofsealing element 36 abuts againstpiston 32 and substantially seals fluid flow from thesource 16 of positive fluid pressure topatient interface unit 12.Aperture 34 is now aligned with opening 27 ofhousing 20 and thus slidingelement 30 permits fluid flow from thesource 14 of negative fluid pressure topatient interface unit 12. Thus,manual valve 18 may operate like a two-way valve. - A working cycle of
inexuflator 10 for providing air to a patient and suddenly causing the patient to cough is now described with reference to FIGS. 2 and 3. In FIG. 2, a user (not shown) supplies positive fluid pressure from thesource 16 of positive fluid pressure viamanual valve 18 topatient interface unit 12, which pressure is forced into the airways and respiratory system of the patient. The positive pressure may be monitored and controlled to suit the needs of the patient by observingpressure sensor 28. Within a predetermined period of time, preferably rapidly and suddenly, the user movesmanual valve 18 to the second orientation shown in FIG. 3. For example, the user may suddenly and quickly slide slidingelement 30 in the direction ofarrow 50, thereby substantially sealing fluid flow from thesource 16 of positive fluid pressure topatient interface unit 12, while generally simultaneously providing negative fluid pressure from thesource 14 of negative fluid pressure viamanual valve 18 topatient interface unit 12. The sudden application of negative pressure to the lungs that have been insufflated with the positive pressure may generate a rapid airflow out of the lungs of the patient, thereby simulating a cough (exuflation). After a predetermined period of time, such as but not limited to about 1 second, the manual valve may be returned to the first orientation to start the working cycle again. - It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the features described hereinabove as well as modifications and variations thereof which would occur to a person of skill in the art upon reading the foregoing description and which are not in the prior art.
