Description

CATHETER APPLICATION STRAP

BACKGROUND OF THE INVENTION

The instant invention relates generally to venoclysis catheters and intravenous set devices used for intravenous transfusions and, more specifically, to venoclysis and intravenous application devices which securely hold the venocath and the i.v. set tube in position.

At the current state of the art, a patient must be restrained of free movement after a venoclysis is applied so that the venocath and i.v. set tube remains in place and so that no displacement, infiltration, thrombophlebitis, injury to the blood vessel results.

Usually, a venoclysis is applied with the use of medical tapes and splints, which applies pressure on the insertion point and discomfort at the patients limb, thereby reducing fluid flow of the blood vessel and give limited support to the venocath and i.v. set tube to any biasing force.

SUMMARY OF THE INVENTION

It is therefore, a primary object to the present invention to provide a Catheter Application Strap which holds the venocath and i.v. set tube in a secured position.

A further object is to provide a Catheter Application Strap which eliminates pressure within the insertion point area from the limb.

A yet further object is to provide a Catheter Application Strap which permits complete free patients movement while keeping the venocath and i.v. set tube in a fixed position relative to the insertion point without the use of medical tapes or restraining devices.

A yet further object is to provide a Catheter Application Strap which adjust to limbs of various diameter at the dorsal, ventral or cubital area of a patient.

A yet further object is to provide a Catheter Application Strap which adheres to the skin to prevent slipping, covers the insertion point transparently for protection and clear visual check and protects against bruising on impact.

A yet further object is to provide a Catheter Application Strap which is simple to administer and remove and does not irritate the skin or a hairsute area.

A yet further object is to provide a Catheter Application Strap which is weather proof for outdoor use and out patient treatment.

A yet still further object is to provide a Catheter Application Strap which is time saving for the attending staff and comforts the wearer.

A yet still further object to provide a Catheter Application Strap which is simple in design and inexpensive to fabricate.

Another yet still further object is to provide a Catheter Application Strap which assimilates the venocath and can be disposed off as compact unit and to prevent cross contamination.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only and that changes may be made in the specific construction illustrated and described within the scope of the appended claims
