Abstract
Abstract A tubular adaptor is adapted to be interposed between an intravenous catheter and a needle carried by a tube holder for housing an evacuated tube for blood-sampling purposes. The adaptor is readily separable from the catheter by means of a tapered-socket fitting, and in this manner, either blood-sampling or intravenous-feeding may be accomplished at the same catheterized situs. The needle and evacuated tube assemblage are isolated from the situs by means of the adaptor and catheter. The flexibility of the catheter tube also serves to isolate the assemblage from the situs whereby adverse effects created by the assemblage during sampling procedures are not impressed upon the situs.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
Apparatus for facilitating both intravenous and blood-sampling procedures, comprising: evacuated tube means for collecting a blood sample; needle means operatively connected with said tube means for supplying said blood sample thereto; an adaptor releasably connected with said needle means for transferring said blood sample from a catheter to said needle means; and a flexible intravenous catheter having a socket means integrally bound therewith, said socket means constructed to separably receive said adaptor to form a temporary connection with said catheter so as to be able to withdraw blood from a mammalian blood vessel and said socket means being readily connectable to a source of intravenous fluid when said adaptor is not connected to said catheter; whereby said catheter may be utilized to perform both said blood-sampling and intravenous-feeding procedures without removing said catheter from a blood vessel such that intravenous feeding takes place at the blood-sampling site.
Claim 2
Dependent Claim
147 words
Apparatus for facilitating both intravenous and blood-sampling procedures, comprising: evacuated tube means for collecting a blood sample; needle means operatively connected with said tube means for supplying said blood sample thereto; an adaptor releasably connected with said needle means for transferring said blood sample from a catheter to said needle means; and a flexible intravenous catheter having a socket means integrally bound therewith, said socket means constructed to separably receive said adaptor to form a temporary connection with said catheter so as to be able to withdraw blood from a mammalian blood vessel and said socket means being readily connectable to a source of intravenous fluid when said adaptor is not connected to said catheter; whereby said catheter may be utilized to perform both said blood-sampling and intravenous-feeding procedures without removing said catheter from a blood vessel such that intravenous feeding takes place at the blood-sampling site.
Claim 3
Dependent Claim
37 words
The apparatus as set forth in claim 1, wherein: said socket means is tapered at the distal end thereof the proximal end of said adaptor is tapered in a manner corresponding to that of said tapered socket.
Claim 4
Dependent Claim
23 words
The apparatus as set forth in claim 1, wherein: said adaptor is a tube interposed between said catheter means and said needle means.
Claim 5
Dependent Claim
36 words
The apparatus as set forth in claim 1, wherein: said socket means has a tapered configuration; and the proximal end of said adaptor is tapered in a manner corresponding to that of said tapered socket means.
Claim 6
Dependent Claim
22 words
The apparatus as set forth in claim 1, further comprising a tube holder for holding said evacuated tube during said blood-sampling procedure.
Claim 7
Dependent Claim
22 words
The apparatus as set forth in claim 5, wherein: said adaptor is a tube interposed between said catheter and said needle means.
