A needle assembly including a needle having a pointed end, the needle being removably secured to a flexible air breathable bandage which is folded, the needle extending from one corner thereof in the cross-folded form. The needle is provided with a flexible connecting tube and a connector for attachment to a user device. The flexible bandage forms a manipulable winged handle in the initial folded form, and serves to enable the insertion of the needle into a patient's body, after which the bandage is unfolded and is adhered to the skin of the patient's body, preferably by adhesion of a pressure sensitive adhesive surface on one face of the bandage. In the unfolded form the bandage covers the puncture site, and after needle use the needle may be removed while leaving the bandage in place, leaving the puncture site covered by the bandage.

BRIAN Ev BALDWIN INVENTOR ATTORNEY NEEDLE ASSEMBLY HAVING A FOLDED BANDAGE HANDLE This is a continuation, of application Ser. No. 42,713 filed June 2, 1970, now abandoned.
This invention relates to an attachable needle assembly for removable attachment to a body member, and more particularly to a manually manipulable needle assembly for insertion into and attachment to a patients body, such as for intravenous therapy or testing (using a hollow needle and fluid connection thereto), or for electrical signal.
In the art of intravenous therapy it is necessary to insert a needle into the vein of a patient, and to retain the needle in place for an extended period of time, the time varying with the particular intravenous therapy or testing involved. It has been previously proposed and practiced to insert such intravenous needles manually into the vein, as by holding the needle or needle holder and puncturing the body, after which a strip of adhesive may be applied to the needle to hold such in place. This method requires the operator to have ready a strip of adhesive. and to thereupon apply the adhesive while holding the needle in place. While such is to some degree satisfactory, it has been found desirable to provide better methods and arrangements for needle insertion and attachment to the body.
One such prior arrangement is shown in US. Pat. No. 3,064,648, which includes a needle with a semi-flexible plastic wing section permanently connected to the needle and having weakened portions which enable the plastic wing sections to be elastically folded to form a manual handle. This device readily enables the manual insertion of the needle. The subsequent securing of the needle to the patients body is accomplished by the employment of a strip of adhesive tape which appears to be placed directly over the down-folded wings to cover the wings and adhere to a portion of the body adjacent the wings. This device does have the advantage of providing a handle for the hand of the operator, but has a number of distinct disadvantages, including the requirement for the additional securing tape to be added thereto to secure the needle assembly to the patients body. In addition, this needle assembly provides no self-contained portion for covering the puncture site, and this leaves it to the operator to decide whether to cover this site, although such in fact is desirable as an aid to prevention of contamination. The device also tends to prevent skin breathing in the zone over which the down-folded wings lie, as the wings are formed of solid or continuous plastic material. There are also distinct pressure points or zones at the edge junction of the wings with the secure surface, and this edge junction also forms a bacteria collection point inasmuch as the skin is depressed along this zone by the tape-down of the plastic wings to the patients skin. The device also requires the removal or release of the adhesive tape securing strip and the removal of the entire attachable needlc assembly, including the needle and plastic wings, in order to remove the needle from the patient.
It is an object and feature of the present invention to provide an attachable needle assembly which enables an operator to manually manipulate, insert and secure the needle in place without touching the needle, and which incorporates a multi-use bandage which serves both as a manually manipulable handle for needle insertion and as a needle securing bandage and sitecovering bandage after insertion of the needle.
It is still a further object and feature of the invention to provide a manually manipulable needle and bandage assembly which enables the ready manual insertion of the needle, the self-contained securing of the needle to the body and the covering of the puncture site by the bandage which initially enables manual manipulation and insertion of the needle.
It is a further object and feature of the invention to provide a manually manipulablc wing-forming selfadhering bandage and needle assembly which enables covering of the needle puncture site and subsequent removal of the needle without removal of the bandage from its covering of the needle puncture site, whereby the bandage can be left in place and continue to provide effective cover for the puncture site.
It is an additional object and feature of the invention to provide a needle and bandage assembly, in which the bandage serves as a manual handle in a folded form thereof, and subsequently serves as a self-contained needle securing means in unfolded condition, and in which the bandage has a pressure sensitive adhesive thereon for ease of self-adhering attachment to a pa tient's body, the bandage being formed of air breathable material for patient comfort and minimization of skin irritation.
Still a further feature of the invention is the provision of a combined needle and bandage arrangement which enables the bandage to be adhered to a body to hold the needle in place after puncture of the body by the needle with the aid of the bandage as a manual handle, and which enables the needle to be easily removed from the puncture site without requiring the bandage to be removed, either simultaneously or prior to the removal of the needle, thereby materially reducing the likelihood of vein damage which might otherwise result from bandage arrangements where removal of the needle requires removal of the adhered bandage.
Still other objects, features and attendant advantages will become apparent to one skilled in the art from a reading of the following detailed description of a pre ferred embodiment constructed in accordance with the invention, taken in conjunction with the accompanying drawings wherein:
