Intravascular access device positioning system
First Claim
1. An apparatus for maintaining intravascular access device in position at an access point on a limb of a patient, said intravascular access device including a needle member introduced into a blood vessel and a connecting tube coupled to said needle member, said apparatus comprising:
- a needle immobilizing unit engaging said needle member and preventing the same from dislodgement from the blood vessel;
a tube locking member immobilizing said connecting tube in place and preventing the same from being separated from said needle member;
a supporting structure supporting said needle immobilizing unit in substantial proximity to the access point on the limb of the patient, and further supporting said tube locking member, said supporting structure including a strap member encircling a respective part of the limb of the patient, and means on said strap member for adjusting the length thereof to substantially match a circumference of the respective part of the limb of the patient; and
, at least one splint member affixable to the respective part of the limb of the patient by said strap member slidable along said at least one splint member.

Abstract
An apparatus for maintaining an intravascular access device in position at an access point on a limb of a patient includes a needle immobilizing unit engaging the needle member and preventing it from dislodgement from the blood vessel, a tube locking member locking the connecting tube in place and preventing it from being separated from the needle member, and a strap which supports the needle immobilizing unit and the locking member immovably on the limb of a patient. For further support of the apparatus in place, a splint assembly is provided which includes two splint members, forearm splint member which is secured to the forearm part of the limb and arm/hand splint member which is securable to either the arm or hand of the limb. The splint members can be used separately or coupled to each other; joint between the splint members has a latching mechanism allowing to adjust the angle between the forearm and arm/hand splint members. The strap carrying the needle immobilizing unit and the tube locking member is secured to a splint member and facilitates in securing the splint.

11. A method for maintaining an intravascular access device in position at an access point on a limb of a patient during therapy, said intravascular access device including a needle member introduced into a blood vessel aid having needle wings, and a connecting tub e coupled to said needle member, said method comprising the steps of:
-
providing a strap member carrying a needle immobilizing unit and a tube locking member thereon;
positioning said strap member adjacent to the access point on the limb of the patient and adjusting the length of said strap member to substantially match a circumference of the limb of the patient;
locking said needle member at the access point on the limb of the patient by capturing said needle wings with said needle immobilizing unit;
locking said connecting tube in place by means of said tube locking member, thereby preventing displacement of said intravascular access device;
providing a first splint member, affixing said first splint member to a respective part of the limb of the patient;
securing said strap member to said first splint member;
providing a second splint member and coupling said first and second splint members at respective ends thereof, securing a second strap member carrying another said needle immobilizing unit and another said tube locking member thereon to said second splint member;
affixing said second splint member to another respective part of the limb of the patient; and
locking another intravascular access device in position on the another respective part of the limb of the patient by means of said another needle immobilizing unit and said another tube locking member. - View Dependent Claims (12)
