Abstract
Abstract A system for monitoring the central venous pressure of a medical patient and, in particular, a manometer scale and flexible manometer-tube combination in such system wherein the liquid level in the tube is easily readable with reference to the index marks on the scale. The scale in a preferred form of the invention is frictionally retained by and slidable along the tube in a manner hereinafter described.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
In combination, an intravenous bottle having a drip control, an intravenous supply tube coupled at one end to said intravenous bottle at said drip control, a catheter assembly having a catheter extension coupled to the remaining end of said intravenous supply tube at a junction, clamping means disposed on said intravenous supply tube, a flexible manometer tube coupled at one end to said junction and having a remaining, upwardly extensible end, clamping means disposed upon said manometer tube, and a manometer scale having securement means slidably and frictionally engaging, and thereby supporting said manometer scale from, said manometer tube above said manometer tube clamping means, and wherein said manometer scale comprises an elongate scale having an angulated cross section, said manometer tube being disposed at the vertex of said angulated cross section, said securement means frictionally retaining said manometer tube against said manometer scale proximate said vertex.
Claim 2
Dependent Claim
147 words
In combination, an intravenous bottle having a drip control, an intravenous supply tube coupled at one end to said intravenous bottle at said drip control, a catheter assembly having a catheter extension coupled to the remaining end of said intravenous supply tube at a junction, clamping means disposed on said intravenous supply tube, a flexible manometer tube coupled at one end to said junction and having a remaining, upwardly extensible end, clamping means disposed upon said manometer tube, and a manometer scale having securement means slidably and frictionally engaging, and thereby supporting said manometer scale from, said manometer tube above said manometer tube clamping means, and wherein said manometer scale comprises an elongate scale having an angulated cross section, said manometer tube being disposed at the vertex of said angulated cross section, said securement means frictionally retaining said manometer tube against said manometer scale proximate said vertex.
Claim 3
Dependent Claim
143 words
In combination, an intravenous bottle having a drip control, an intravenous supply tube coupled at one end to said intravenous bottle at said drip control, a catheter assembly having a catheter extension coupled to the remaining end of said intravenous supply tube at a junction, clamping means disposed on said intravenous supply tube, a flexible manometer tube coupled at one end to said junction and having a remaining, upwardly extensible end, clamping means disposed upon said manometer tube, and a manometer scale having securement means slidably and frictionally engaging, and thereby supporting said manometer scale from said manometer tube above said manometer tube clamping means, and wherein said manometer scale comprises a unitary, elongate manometer scale of angulated transverse cross section, said manometer scale including tab means as said securement means for frictionally though slidably retaining said manometer tube against said manometer scale.
Claim 4
Dependent Claim
143 words
In combination, an intravenous bottle having a drip control, an intravenous supply tube coupled at one end to said intravenous bottle at said drip control, a catheter assembly having a catheter extension coupled to the remaining end of said intravenous supply tube at a junction, clamping means disposed on said intravenous supply tube, a flexible manometer tube coupled at one end to said junction and having a remaining, upwardly extensible end, clamping means disposed upon said manometer tube, and a manometer scale having securement means slidably and frictionally engaging, and thereby supporting said manometer scale from said manometer tube above said manometer tube clamping means, and wherein said manometer scale comprises a unitary, elongate manometer scale of angulated transverse cross section, said manometer scale including tab means as said securement means for frictionally though slidably retaining said manometer tube against said manometer scale.
Claim 5
Dependent Claim
20 words
Structure according to claim 2 wherein said tab means are sheared from and displaced forwardly of said angulated cross section.
Claim 6
Dependent Claim
111 words
A manometer scale comprising an elongate manometer scale base, and resilient tab means integral with said manometer scale base for receiving and slidably securing a manometer tube against said manometer scale base, wherein said manometer scale base includes a zero pressure index, positive pressure indexes incrementally disposed above said zero pressure index, and negative pressure indexes incrementally disposed beneath said pressure index, and wherein said manometer scale base has an angulated transverse cross section, said tab means being disposed in spaced relation over said manometer scale and thereby being constructed and arranged to slidably retain a manometer tube disposed between said tab means and said manometer scale base against the latter.
Claim 7
Dependent Claim
111 words
A manometer scale comprising an elongate manometer scale base, and resilient tab means integral with said manometer scale base for receiving and slidably securing a manometer tube against said manometer scale base, wherein said manometer scale base includes a zero pressure index, positive pressure indexes incrementally disposed above said zero pressure index, and negative pressure indexes incrementally disposed beneath said pressure index, and wherein said manometer scale base has an angulated transverse cross section, said tab means being disposed in spaced relation over said manometer scale and thereby being constructed and arranged to slidably retain a manometer tube disposed between said tab means and said manometer scale base against the latter.
