Abstract
Abstract An intravenous catheter shield is formed by a base underlying a portion of the patient's limb containing an infusion needle. A transparent channel-like housing is hingedly connected with the base and overlies the catheter area in vertical spaced relation. Velcro equipped straps secure the patient's limb to the base and the outer surface of the housing is provided with resilient clamps which grip an IV tube extending across the housing and into its interior for connection with the catheter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
258 words
A shield for protecting the position of an intravenous needle having a supply tube connected at one end thereto when the needle is inserted in a body part of a patient, comprising: an elongated generally rectangular planar base for underlying the terminal end portion of a patient's limb, said base having a plurality of elongated slots adjacent opposing longitudinal side edges; flexible means for securing said base to the patient's limb in an immobilizing manner, said flexible means including, a like plurality of elongated straps respectively extending through said plurality of slots and surrounding a portion of said base and patient's limb thereon, each strap of said plurality of straps having opposing end portions disposed in overlapping relation; self-adhering fabric material cooperatively secured to said strap opposing end portions for releasably joining said end portions together; a rigid inverted open end channel-like transparent housing substantially U-shape in transverse cross section having coextensive depending leg portions and an arcuate bight portion longitudinally overlying the base in laterally and vertically spaced relation with respect to the surface of the patient's limb and an intravenous needle position; means releasably securing the housing leg portions to respective side edge portions of said base, said housing releasable means including, an upstanding pin adjacent respective opposing longitudinal side edges of said base and, a vertically apertured lug adjacent the depending limit of the housing respective leg portion for cooperative frictional reception of said pin; and, spring clamp means on said housing for securing one end portion of a needle supply tube to said housing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
183 words
A shield for protecting the position of an intravenous needle having a supply tube connected at one end thereto when the needle is inserted in a body part of a patient, comprising: an elongated generally rectangular planar base for underlying the terminal end portion of a patient's limb;, flexible means for securing said base to the patient's limb in an immobilizing manner; a rigid inverted open end channel-like transparent housing substantially U-shape in transverse cross section having co-extensive depending leg portions and an arcuate bight portion longitudinally overlying the base in laterally and vertically spaced relation with respect to the surface of the patient's limb and an intravenous needle position; means releasably securing the housing leg portions to respective side edge portions of said base, said housing releasable means including, an upstanding pin adjacent respective opposing longitudinal side edges of said base, a vertically apertured lug adjacent the depending limit of the housing respective leg portion for cooperative frictional reception of said pin; and, spring clamp means on said housing for securing one end portion of a needle supply tube to said housing.
Claim 4
Dependent Claim
183 words
A shield for protecting the position of an intravenous needle having a supply tube connected at one end thereto when the needle is inserted in a body part of a patient, comprising: an elongated generally rectangular planar base for underlying the terminal end portion of a patient's limb;, flexible means for securing said base to the patient's limb in an immobilizing manner; a rigid inverted open end channel-like transparent housing substantially U-shape in transverse cross section having co-extensive depending leg portions and an arcuate bight portion longitudinally overlying the base in laterally and vertically spaced relation with respect to the surface of the patient's limb and an intravenous needle position; means releasably securing the housing leg portions to respective side edge portions of said base, said housing releasable means including, an upstanding pin adjacent respective opposing longitudinal side edges of said base, a vertically apertured lug adjacent the depending limit of the housing respective leg portion for cooperative frictional reception of said pin; and, spring clamp means on said housing for securing one end portion of a needle supply tube to said housing.
