A connecting device for use in an apparatus for transfer of blood from a human to a vacuumized blood culture bottle comprising; elongated body means having a passage therethrough; a cavity opening outwardly of one end of said body; a needle pierceable plug sealingly positioned in said cavity; a hollow needle secured in the opposite end of said body and projecting outwardly therefrom; said hollow needle communicating with the passage in said body; an opening intermediate the ends of said body and extending radially from the outer surface of said body to said passage; air filter means secured in said opening; and means detachably connected to said body for sealing the outer end of said air filter.

Claim 3

A connecting device as set forth in claim 1, and further including caps detachably applied to and sealing the ends of said body.

Claim 4

In combination with a vacuum adapter including a sheath having an open end and an end wall disposed remote from said open end in which is mounted an intermediate portion of a first tubular needle, and a vacuumized blood culture bottle having a rubber plug sealing the neck thereof; a connecting means including an elongated body having an end sized to fit slidably in said sheath and having a cavity opening outwardly of said end, a rubber plug sealing an outer end of said cavity and penetrated by an inner end of the needle when said body end is inserted into the sheath, a second hollow needle having one end secured in the opposite end of said body and an exposed opposite end projecting from said last mentioned body end to penetrate the bottle stopper when the bottle neck is displaced endwise toward said last mentioned body end, said body having a passage connecting the cavity thereof to the bore of the second needle for vacuumizing the bore of the first needle when the bore of the second needle is in communication with the interior of the bottle an air filter disposed in and opening outwardly of said body and a port connecting an inner end of said filter to said passage of the body between the adjacent ends of the needles, and means detachably connected to the body for sealing the outer end of said air filter.

Claim 5

In combination with a vacuum adapter including a sheath having an open end and an end wall disposed remote from said open end in which is mounted an intermediate portion of a first tubular needle, and a vacuumized blood culture bottle having a rubber plug sealing the neck thereof; a connecting means including an elongated body having an end sized to fit slidably in said sheath and having a cavity opening outwardly of said end, a rubber plug sealing an outer end of said cavity and penetrated by an inner end of the needle when said body end is inserted into the sheath, a second hollow needle having one end secured in the opposite end of said body and an exposed opposite end projecting from said last mentioned body end to penetrate the bottle stopper when the bottle neck is displaced endwise toward said last mentioned body end, said body having a passage connecting the cavity thereof to the bore of the second needle for vacuumizing the bore of the first needle when the bore of the second needle is in communication with the interior of the bottle an air filter disposed in and opening outwardly of said body and a port connecting an inner end of said filter to said passage of the body between the adjacent ends of the needles, and means detachably connected to the body for sealing the outer end of said air filter.

Claim 6

In a combination as defined by claim 3, said body having a skirt extending from the last mentioned end thereof and disposed around the last mentioned end of the second needle, said skirt being sized to receive the bottle neck and to provide a seat for the bottle stopper.

Claim 7

In a combination as defined by claim 3, said passage of the body being of a diameter substantially greater than the diameter of the bores of the needles.
