Vacuum control valve 11 and connectingmember 14 are known. Therefore, suffice it to say thatvacuum control valve 11 comprises acover 11 a marked with anarrow 11 b (indicated in the closed position inFIG. 1 ). When necessary, the operator applies finger pressure oncover 11 a and rotates it to setarrow 11 b to a vacuum source (not shown) to aspirate bronchial mucus. Only witharrow 11 b set to this position, can secretion be aspirated; in any other position ofarrow 11 b, aspiration is prevented. - As shown in detail in
FIG. 2 ,catheter body 12 comprises atransparent sleeve 15 made of easily deformable, tear-proof plastic material, and which protects acatheter 16 from contamination to and from an external environment. In know manner,catheter 16 comprises a number ofdepth marks 17 to enable the user to monitor insertion of suction catheter 16 (of minimum 5 Ch size) inside the tracheal/tracheostomic tube. - As shown in
FIG. 2 , betweencatheter body 12 andbronchotracheal access valve 13 are inserted a fitting 18 for guidingcatheter 16, and abushing 19 for securingtransparent sleeve 15 to fitting 18. - As stated, the innovative part is defined by
bronchotracheal access valve 13, which is shown in detail in the exploded views inFIGS. 2 , 7, and 8. - All the component parts of
bronchotracheal access valve 13 are made of transparent plastic material. - With reference to the accompanying drawings,
bronchotracheal access valve 13 comprises a substantially disk-shapedfirst member 20, and a substantially cup-shaped second member 21 (FIGS. 2 , 7, and 8). -
Second member 21 in turn comprises a cup-shapedmain body 22, from asurface 22 a (FIG. 4 ) from which projects a through conduit 23 (e.g. insertion means), for passage of acatheter 16. Thethrough conduit 23 is fixed, in use, to fitting 18 (FIG. 1 ). A flush conduit 24 (e.g. flush means) projects also from thesurface 22 a.Conduits main body 22. - As shown in
FIGS. 1 , 2, 7, and 8, aflush tube 25 is inserted insideconduit 24, and has acap 26 connected to it by atie 27. - As shown particularly in
FIG. 7 ,main body 22 has 25 three weight-reducingholes 28 located 120° apart, and at each of which arespective tab 29 is formed by conveniently cutting anedge 22 b ofmain body 22. - The function of the three
tabs 29 is explained below. - As shown in
FIGS. 3 , 4, 5, and 6, achannel 30 is integrated in the inner wall ofconduit 23, originates at a point P1 at the bottom ofconduit 23, and terminates at a point P2 (FIGS. 3 and 4 ). - The functions of
channel 30 are explained below, in the section dealing with the operation ofbronchotracheal access valve 13. - A surface 22 c of
main body 22 has a locating pin 31 (FIG. 2 ) which fits inside a locatinghole 32 formed in the center of first member 20 (FIGS. 5 and 6 ). The inner surface ofedge 22 b has apin 33, which, in use, engages a guide duct 34 (FIGS. 5 , 6, 7, and 8) formed on anedge 20 a offirst member 20, for the reasons explained in detail below. - For the time being, suffice it to say that
pin 33 andguide duct 34 define a stop device. - As shown in
FIGS. 2 , 3, 4, 7, and 8, a through sleeve 35 (e.g. connecting means) projects from asurface 20 b offirst member 20, and is connected, in use, to conduit 14 b of connectingmember 14. - In addition to locating
hole 32 andguide duct 34, asurface 20 c of first member 20 (FIGS. 7 and 8 ) also comprises a substantiallysemicircular duct 36. -
Surface 20 c also comprises a number ofducts 37 for housing anelastomer seal 38. -
Seal 38 obviously provides for hydraulically sealingduct 36 from the mouth ofsleeve 35. - That is, seal 38 (e.g., a selective communication means), as will be seen, prevents the flush fluid from accidentally flowing from
duct 36 to the mouth ofsleeve 35. - During assembly,
first member 20,second member 21, and seal 38 (inserted inside ducts 37) are “packed” tightly (FIGS. 7 and 8 ) together using the deformability oftabs 29 onsecond member 21, which grip ontoedge 20 a offirst member 20. - In other words, during assembly,
main body 22 ofsecond member 21 “clicks” ontofirst member 20 using the deformability oftabs 29 formed fromedge 22 b and therefore made of plastic material. - In actual use,
second member 21 can be rotated by the operator with respect tofirst member 20 in the direction indicated by arrow F1 (and about locating pin 31) to movebronchotracheal access valve 13 from a first configuration, shown inFIG. 5 , to a second configuration, shown inFIG. 6 . In the first configuration inFIG. 5 ,pin 33, integral withsecond member 21, is set to a limit position A alongguide duct 34 infirst member 20, andconduit 23 is aligned withsleeve 35, withconduit 14 b, with fitting 18, and withbusing 19, so thatcatheter 16 can fit throughconduit 23,sleeve 35, andconduit 14 b to the desired areas of the patient's body. - In the first configuration in
FIG. 5 ,flush conduit 24 terminates at one end insideduct 36. However, sinceduct 36 in this configuration does not communicate hydraulically withconduit 23 orchannel 30, the flush fluid, even if injected by the operator inadvertently intoduct 36 throughconduit 24, is also prevented byseal 38 from reachingconduit 23 orchannel 30. - To flush an
end portion 16 a (FIG. 2 ) ofcatheter 16, the operator simply withdrawscatheter 16 to pullend portion 16 a out of sleeve 35 (FIG. 4 ), and rotatessecond member 21 with respect tofirst member 20 in the direction of arrow F1, so thatpin 33 is set to a limit position B (FIG. 6 ) alongguide duct 34, and one end ofchannel 30 is positioned onduct 36.Flush conduit 24 is also rotated in the direction of arrow F1, but a free end of it is still maintained contactingduct 36. - This therefore results in the
FIG. 6 configuration, in which, flush fluid injected by the operator intoflush conduit 24 flows along duct 36 (arrow F2 inFIGS. 4 and 6 ) intochannel 30 and out at point P2 to floodconduit 23 and soflush end portion 16 a ofcatheter 16. It should be pointed out that, whensecond member 21 is rotated with respect tofirst member 20 in the direction of arrow Fl,surface 20 c of first member 20 (FIGS. 7 and 8 ) closes the end ofconduit 23, thus preventing accidental backflow of the flush fluid fromconduit 23 to the patient throughsleeve 35 andconduit 14 b. - Once flushing is completed, the flush fluid is drained from
conduit 23 by known drain systems. - Once
end portion 16 a is flushed, the operator simply rotatessecond member 21 with respect tofirst member 20 in the opposite direction to arrow F1, and then pushescatheter 16 back intosleeve 35 andconduit 14 b to continue treatment of the patient. - As will be clear from the foregoing description, the main advantage of the bronchotracheal access valve, which is the main object of the present invention, lies in it being designed to only permit flushing of the end of the catheter in conditions ensuring the utmost safety of the patient.
