Blood collection apparatus
First Claim
1. A blood collection apparatus (100) comprising:
- a blood collection assembly (10) comprising;
a casing tube (11) including a forward nose (12), a plurality of connectors (111-115) and a rear flange (13) having a flexible projection (131); and
a plunger (30) slidably disposed into the casing tube (11) and comprising a forward plug (31) and an elongated arm (32) including a plurality of cavities (321-325);
a plurality of blood collection tubes (501-505);
a plurality of adapter assemblies (40) each including a tube body (41), a first tube (411-415) extending out of one end of the tube body (41) to insert into one of the connectors (111-115) of the casing tube (11), and a second tube (421) extending out of another end of the tube body (41) to insert into one of the blood collection tubes (501-505); and
a butterfly needle assembly (20) mounted to the nose (12) of the casing tube (11);
wherein in a blood collection operation of pulling of the plunger (30) moves the plug (31) rearward and pivots the projection (131) to engage in one of the cavities (321-325) of the elongated arm (32) and an orifice (101-105) of each said related connector (111-115) is not blocked by the plug (31) so as to flow blood from the casing tube (11) to one of the blood collection tubes (501-505) via one of the connectors (111-115) and one of the adapter assemblies (40).
