Description

DISPOSABLE VENOCLYSIS ADAPTER DEVICE

BACKGROUND OF THE INVENTION

The instant invention related generally to venoclysis cathet er and intravenous set devices used for intravenous transfusions and, more specifically, to venoclysis and intravenous adaptor devices which securely hold the venocath or butterfly 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/or butterfly remains in place and so that no infiltration, thrombophlebitis, injury to the blood vessel or the surrounding tissue results.

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

SUMMARY OF THE INVENTION

It is therefore, a primary object to the present invention to provide a disposable venoclysis adaptor device which securely holds the veneoath or the butterfly in position.

A further objection is to provide a disposable venoclysis adaptor device which eliminates pressure within the insertion point area from the limbs.

A yet further object is to provide a disposable venoclysis adaptor device which permits complete free patients movement while keeping the veneoath or butterfly in a fixed position relative to the insertion point without the use of any restraining device.

A yet further object is to provide disposable venoclysis adaptor device which adjust to limbs of various diameter at the dorsal or ventral area and keeps the insertion point open for checking.

A yet further object is a provide disposable venoclysis adaptor device which is simple to administer and remove and doe snot irritate the skin or a hairsute area.

A yet still further object is to provide disposable venoclysis adaptor device which provides time saving and practical means and comforts the wearer.

Another yet still further object to provide disposable venoclysis adaptor device which is simple in design and inexpensive to fabricate.

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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention 10 is a flexible fastening strap 12, which is shown as typical of the hook with pressure sensitive adhesive backing 15 and the loop 18 pile fastener type, permanently secured 20 overlapping hook 14 and one end of loop 18 to form a compact fastening strap 12, to be wrapped around a patients limb, however, it is understood that any suitable adhering material, such as pressure sensitive adhesive tape ribbon might also be used in place of the pile fastener type.

The overlapping and of hook 14 with pressure sensitive adhesive backing is the tube flap 22 which adapts a tube 52 of the venoomth 46 of butterfly 48 when placed between tube flap 26 and loop 16.

Two distance cushions 24 wit a hard board back 26 which is shown as a one layer board, absorbent padding as surmounts hard board back 26 and absorbs body moisture from the wearer through a woven or non-woven fabric 30 covering absorbent padding 28. he juncture of woven or non-woven fabric 30 and hard board back 26 is permanent sealed/attached as shown as peripheral edges 32.

Needlestripes 58 of rubberized ink printed on the distance cushions 24 at the surface of the woven or non-woven fabric 30 is to prevent slipping at the wearers skin.

Two distance cushions 24 permanently attached at the hard board back 26 to fastening strap 12 at the pressure sensitive adhesive backing 16 of the hook 14 to keep the fastening strap 13 at distance from the insertion point of venooth 46 or butterfly 48 at any given area applied.

Between the two distance cushions 24 an adaptor pillow 34 is placed permanently at the pressure sensitive adhesive backing 16 of the hook 14 as illustrated, which consists of a soft pad 36, covered with a fabric mesh 20 laminated at soft pad 36 at the exposed side, which snows a film of pressure sensitive adhesive 40 applied at the fabric mesh 30. When not in use the pressure sensitive adhesive film 40 is covered with a strip of release paper 42 which is pulled off at the time of application.

An adaptor flap 44 of woven or non-woven fabric ribbon material is permanently attached between one distance cushion 24 and the adaptor pillow 34 pointing at its lose end towards the second distance cushion 24, which when applied, after a veneoath 46 or butterfly 48 is administered, is slipped under the venetube or butterfly and sandwiched by the adaptor pillow 34 which secures the veneoath 46 or butterfly 40 safely at the disposable venoclysis adaptor device 10 which is then wrapped around a patients limb and secured by fastening strap 12. With the excess tube 53, a small loop 50 is formed and sandwiched at tube flap 22 and loop 18.

An extended pair of distance cushions' ^'54 permanently attached to a second fastening strap 56 which is shown as typical of the hook 14 and loop 18 pile fastener type, which gives added support to the disposable venoclysis adaptor device 10 at the patients limb.

A single extended distance cushion restraining attachments so provided with slots 52 from insertion of the loop 12/18 pile fastener type of the invention 10, placed at the opposite side of the insertion point of a patient limb, particularly on infants, provided with a fastening strap 64 which is sown as typical of the hook 14 and loop 18 pile fastener type, when closed restraining a limbs movement.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
