Abstract
Abstract A device for protecting a venipuncture site and retaining a catheter and intravenous tubing at said site, without binding said catheter and tubing or occluding the flow therethrough. Easy accessibility to the venipuncture site and retention site is provided by a hinged cover. Much pain and discomfort associated with frequent removal of adhesive tape from a patient's skin, repeated venipuncture and trauma due to irritation caused by inadvertent catheter movement are eliminated or substantially eliminated because the catheter is disposed in a protective environment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A venipuncture guard for a medical patient comprising: generally flat skin-engaging base means, the base means comprising an opening accommodating placement of the base means around a venipuncture site; lid means comprising means bridging over the venipuncture site in spaced relation thereto comprising means for successively opening and means for closing the lid means in respect to the base means to permit access to the venipuncture site and conceal the site from debris and prevent inadvertent displacement of an intravenous cannula in respect to the vein of a patient at the venipuncture site, respectively; the guard further comprising means defining passageway means by which medical tubing spans between the venipuncture site and the exterior of the guard; the guard further comprising vein bridge means in aligned though axially spaced relation to the venipuncture site which vein means prevents occlusion by the guard of the vein in which the venipuncture site is disposed; and anti-displacement means, associated with the vein bridge means, which prevent inadvertent removal of an indwelling cannula from the venipuncture site.
Claim 2
Dependent Claim
173 words
A venipuncture guard for a medical patient comprising: generally flat skin-engaging base means, the base means comprising an opening accommodating placement of the base means around a venipuncture site; lid means comprising means bridging over the venipuncture site in spaced relation thereto comprising means for successively opening and means for closing the lid means in respect to the base means to permit access to the venipuncture site and conceal the site from debris and prevent inadvertent displacement of an intravenous cannula in respect to the vein of a patient at the venipuncture site, respectively; the guard further comprising means defining passageway means by which medical tubing spans between the venipuncture site and the exterior of the guard; the guard further comprising vein bridge means in aligned though axially spaced relation to the venipuncture site which vein means prevents occlusion by the guard of the vein in which the venipuncture site is disposed; and anti-displacement means, associated with the vein bridge means, which prevent inadvertent removal of an indwelling cannula from the venipuncture site.
Claim 3
Dependent Claim
159 words
A non-occluding, non-crimping retainer for use with an indwelling cannula and connected tubing in conjunction with a medical patient comprising: generally flat skin-engaging base means having a venipuncture site opening disposed at a central site therein; vein bridge means in the base means which prevent occlusion of the vein in which the venipuncture site is located; passageway means associated with the vein bridge means accommodating passage of the intravenous tubing therethrough; anti-displacement means disposed at a second site in close proximity to the passageway means and the vein bridge means and in alignment with the venipuncture site opening, which anti-displacement means securedly anchor the tubing adjacent the passageway means without occluding or crimping the tubing, the second site being in seriatum with the first site; lid means comprising means for opening and means for closing the lid means in respect to the base means to respectively expose and conceal the venipuncture site and the tubing within the passageway means.
Claim 4
Dependent Claim
159 words
A non-occluding, non-crimping retainer for use with an indwelling cannula and connected tubing in conjunction with a medical patient comprising: generally flat skin-engaging base means having a venipuncture site opening disposed at a central site therein; vein bridge means in the base means which prevent occlusion of the vein in which the venipuncture site is located; passageway means associated with the vein bridge means accommodating passage of the intravenous tubing therethrough; anti-displacement means disposed at a second site in close proximity to the passageway means and the vein bridge means and in alignment with the venipuncture site opening, which anti-displacement means securedly anchor the tubing adjacent the passageway means without occluding or crimping the tubing, the second site being in seriatum with the first site; lid means comprising means for opening and means for closing the lid means in respect to the base means to respectively expose and conceal the venipuncture site and the tubing within the passageway means.
Claim 5
Dependent Claim
28 words
A retainer according to claim 2 wherein the anti-displacement means comprise means around which the tubing is wound to create at least one reverse curve in the tubing.
Claim 6
Dependent Claim
156 words
A non-occluding, non-crimping retainer for use with intravenous tubing and the like in conjunction with a medical patient comprising: generally flat skin-engaging base means; passageway means associated with the base means accommodating passage of the intravenous tubing therethrough; anti-displacement means which securedly anchor the tubing within the passageway means without occluding or crimping the tubing; lid means comprising means for opening and means for closing the lid means in respect to the base means to respectively expose and conceal the tubing within the passageway means, the closing means comprise releasable latch means, which latch means comprise mating male-female connectors, the connectors comprising annular means having hollow interior means and post means aligned with and sized to snugly frictionally engage the annular means within the hollow interior means thereof, the annular means and post means comprising at least two sets each of which presents two cylindrical surfaces comprising the anti-displacement means around which the tubing is wound.
Claim 7
Dependent Claim

A non-occluding, non-crimping retainer for use with intravenous tubing and the like in conjunction with a medical patient comprising: generally flat skin-engaging base means; passageway means associated with the base means accommodating passage of the intravenous tubing therethrough; anti-displacement means which securedly anchor the tubing within the passageway means without occluding or crimping the tubing; lid means comprising means for opening and means for closing the lid means in respect to the base means to respectively expose and conceal the tubing within the passageway means, the closing means comprise releasable latch means, which latch means comprise mating male-female connectors, the connectors comprising annular means having hollow interior means and post means aligned with and sized to snugly frictionally engage the annular means within the hollow interior means thereof, the annular means and post means comprising at least two sets each of which presents two cylindrical surfaces comprising the anti-displacement means around which the tubing is wound.
Claim 8
Independent Claim
182 words
A device which guards a venipuncture site of a medical patient and retains the position of intravenous tubing spanning from the venipuncture site to a location exterior of the device, the device comprising: generally flat skin-engaging base means, the base means comprising an opening accommodating placement of the base means around the venipuncture site; passageway means through which the intravenous tubing spans between the venipuncture site and a location exterior of the device; anti-displacement means which securely anchor the tubing within the device against inadvertent displacement thereof without occluding or crimping of the tubing; lid means comprising cavity-defining means bridging over the venipuncture site and the anti-displacement means, the lid means comprising means for successively opening and means for closing the lid means in respect to the base means to permit access to the venipuncture site, and conceal the site from debris and prevent inadvertent displacement of an intravenous cannula in respect to the vein of a patient at the venipuncture site, respectively, said lid means comprising first cover means bridging the venipuncture site and second cover means concealing the anti-displacement means.
