Abstract
A safety device for collecting fluids for laboratory testing is disclosed. More particularly, the invention relates to an apparatus for collecting multiple undiluted blood samples for subsequent laboratory testing wherein the apparatus is provided with a safety overshield which precludes the individual taking the blood sample from sustaining a needle stick injury. The apparatus includes a vacutainer tube retainer to which a safety overshield is attached. The safety overshield has an upwardly projecting peripheral rim which prevents the depositing needle from sliding off the face of the overshield and contacting the hand of the individual holding the vacutainer tube retainer.
Claims22
A safety device for use in collecting fluids into fluid collection tubes having penetrable stopper means inserted therein through a fluid transfer hose having at least one hollow needle attached thereto comprising:
- a fluid collection tube retainer, said retainer including a frame having a plurality of openings therethrough for receiving fluid collection tubes and one or more openings for receiving one end of a fluid transfer hose and a gripable body member having a plurality of grooves for partially engaging said fluid collection tubes;
- and
- a safety overshield selectively attached to said fluid collection tube retainer having a downwardly extending lip which engages said frame, a plurality of openings one the face of said safety overshield which correspond to the openings of said frame, and an upwardly projecting rim about the periphery of said safety overshield.
An apparatus for preventing needle stick injuries while drawing blood for laboratory testing and depositing the blood into evacuated fluid collection tubes having stopper members inserted therein with a phlebotomy needle, comprising:
- a collection tube retainer having an upper peripheral frame and a body portion, wherein said upper peripheral frame has a plurality of openings for receiving said fluid collection tubes and at least one opening for securing said phlebotomy needle, said body portion including a plurality of vertical grooves for preventing lateral movement of said fluid collection tubes and at least one groove for securing a transfer hose;
- and
- overshield means comprising a selectively attached plate member having a plurality of openings corresponding to the openings in said frame for access to said fluid collection tubes, at least one opening for insertion of said phlebotomy needle, a downwardly extending lip which partially engages the periphery of said frame thereby attaching said plate to said retainer and an upwardly projecting rim about the periphery of said plate.
A method of preventing a needle stick injury while collecting fluid samples, comprising the steps of:
- (a) providing one or more fluid collection tubes wherein said tubes have needle penetrable stoppers inserted therein;
- (b) providing at least one fluid transfer hose having first and second hollow needles attached thereto at opposite ends;
- (c) providing a two-piece safety device, said device including:
- a fluid collection tube retainer having openings which house said fluid collection tubes and at least one opening for maintaining said fluid transfer hose;
- and
- a safety overshield attachable to said fluid collection tube retainer, wherein said safety overshield has a plurality of openings which correspond to the openings on said fluid collection tube retainer and an upwardly projecting rim about the periphery;
- (d) inserting said fluid collection tubes into said fluid collection tube retainer;
- (e) attaching said safety overshield to said fluid collection tube retainer;
- (f) drawing fluid into said fluid transfer hose through said first needle;
- (g) inserting said second needle into a fluid collection tube through an opening in said safety overshield and through said penetrable stopper;
- (h) filling said fluid collection tube;
- (i) withdrawing said second needle from said fluid collection tube and storing said needle within the opening for maintaining said fluid transfer hose.
A method of collecting fluid samples using a transfer hose having hollow needles attached at both ends, said method comprising the steps of:
- (a) providing means for collecting said fluid samples, said means having needle penetrable stoppers inserted therein;
- (b) providing means for preventing needle stick injuries, said means including:
- a fluid collection tube retainer having a plurality of openings from which said means for collecting said fluid samples extend;
- and
- an overshield attachable to said fluid collection tube retainer, wherein said overshield has a plurality of openings and an upwardly projecting peripheral rim;
- (c) inserting said means for collecting fluid samples into said fluid collection tube retainer;
- (d) attaching said overshield to said retainer;
- (e) inserting one of said hollow needles into a fluid collection tube through an opening in said overshield and through said penetrable stopper;
- whereby said fluid may now be deposited and collected for laboratory testing.
