Nov. 29,1966 0. w. LUND ANCHORING DEVICE Filed Jan. '7, 1964 INVENTOR DOUGLAS w. LUND BY I ATTORNEY Unite States Patent Q 3,288,137 ANKIHORING DEVICE Douglas W. Lund, R0. Box 1167, Florence, Ala. Filed Jan. 7, 1964, Ser. No. 336,178 3 Claims. (Cl. 128133) This invention relates to the attachment of one element to another element in such a manner that the first element can be angularly adjusted relative to the second element and can be easily and quickly attached thereto, detached or removed and subsequently reapplied.
The invention relates particularly to an anchoring device for an infustion needle or the like which can be rapidly and easily attached and removed from the human skin and which includes a needle holding portion that can be adjusted to hold the needle in any desired angle.
Heretofore, an infusion needle has been inserted into a vein of a patient after which the needle has been supported by one or more rolls of surgical dressing and by several strips of adhesive tape placed over the needle to maintain the needle in fixed position. This method has been awkward and has not always succeeded since the 'patients skin may be wet from a preliminary alcohol wipe, bleeding, or perspiration of the patient. Normally, the attending physician must hold the needle with one hand while he attempts to apply the dressing and adhesive tape with the other hand and generally an assistant is required to separate the strips of adhesive tape from a roll and pass them to the physician when required. Many times the needle has not remained in the vein due to the movement of either the physician or the patient and has resulted in the necessity of reapplying the needle which has consumed time and effort on the part of the physician and has caused additional pain to the patient.
It is an object of the invention to overcome the difiiculties enumerated and to provide a simple, economical anchoring device for an infusion needle which can easily be applied by one person and which will maintain the needle at any desired angle.
Another object of the invention is to provide an anchoring device for an infusion needle which holds the needle at any desired angle and which is easily applied and removed from the skin of the patient.
A further object of the invention is to provide an anchoring device including a pair of separable members, one of which is adapted to be secured to any desired surface and the other is adapted to hold an object in any desired angle with the second member being easily attachable to the first member in a manner that it can be easily removed and reapplied without removing the first member from the surface.
ther objects and advantages of the invention will be apparent from the following description taken in conjunc- FIG. 1 is a perspective illustrating one application of the invention;
FIG. 2, an exploded perspective of the various parts; and
FIG. 3, an enlarged side elevation.
Briefly stated the present invention is an anchoring device whose primary function is to secure an intubation or infusion needle, which has been injected into the vein of a patient, at any desired angle and such device includes a first member which is easily attachable to the dermis or skin of the patient and a second member having a deformable portion adapted to maintain the needle in the vein at the angle determined by the physician, and such second member is easily applicable to and removable from the first member.
With continued reference to the drawing, a hollow tube 1th is provided one end of which may be attached to an infusion flask or other vessel (not shown) containing a ice liquid to be injected into a patient. The opposite end of the tube 10 is connected to a hollow needle 11 and if desired an aspiration bulb 12 may be located intermediate the tube and needle. The needle is adapted to be inserted into the vein of a patient after which the bulb 12 may be squeezed to draw a small amount of blood into the needle which can be observed by the physician, nurse or other person administering the injection to make certain that the needle is located in the vein.
In order to hold the needle in fixed position after it has been inserted, the anchoring device of the present invention comprises a first member including a pad 14 constructed of cloth or other fluffy material 15 with a coating of dermal adhesive 16 on one side thereof which is normally covered by a sheet 17 when not in use. The sheet 17 is treated with an adhesive releasing material so that the sheet may be removed from the pad to expose the adhesive prior to the application of the pad to the skin of the patient.
A second member is adapted to be attached to and removed from the first member and such second member includes a portion or strip of material 18 of synthetic resin or the like having a plurality of hook-forming pile threads 19 of the type illustrated in Patent 2,717,437 and manufactured under the tradename Velcro. A body of deformable material 20 which may be of foraminous or other material capable of being deformed and of retaining the deformed shape is connected to one side of the Velcro material by an adhesive or other fastening. The deformable material 29 has a body 21 of substantially the same size as the portion 18, an intermediate reduced hingeforming portion 22 which projects beyond the strip of material 18 and is adapted to be bent at any desired angle relative to the body '21 and a clamping portion 23 at the end of the reduced portion adapted to be formed or bent into clamping engagement with the needle 11 to hold the needle at any desired angle.
In the operation of the device the approximate point of penetration of the needle into the patients flesh is decided upon by the attending physician or other person administering the injection and the sheet 17 is peeled from the pad 14 after which the pad is applied to the skin. The area of penetration may then be cleansed with an alcohol or antiseptic wipe after which the needle 11 may be injected into the vein of the patient. After the needle has pentrated into the vein the clamping portion 23 of the deformable material is formed about a portion of the needle and the reduced portion 22 is bent to approximately the correct angle after which the second member is placed on the pad 14 of the first member and pressed down so that the hook-forming threads 19 engage the material 15 and become attached thereto. Any subsequent adjustment of the angularity of the reduced portion 22 can then be made and a valve on the infusion flask may be opened to permit the fluid therein to flow by gravity into the vein of the patient.
It will be noted that the anchoring device may be applied to the needle 11 prior to the penetration of the patient so that the only requirement after penetration is the adjusting of the angle.
It will be apparent from the foregoing that a relatively simple anchoring device is provided for holding an infusion needle and that such device may be easily applied and removed and when applied will maintain such needle in a selected position and angle.
It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the in vention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.
What is claimed is:
1. An anchoring assembly for maintaining an infusion needle in fixed position relative to a surface comprising a first member including a pad means having cloth-like material on at least one surface, adhesive means on another sur-face of said pad means for attaching said first member to said surface, a second member re-movably mounted on said first member, said second member including a deformable body, a reduced hinge-forming portion connected to said body and adapted to be bent at an angle thereto, a clamping portion carried by said hinge-forming portion, said body, hinge-forming portion and clamping portion being of foraminous construction of easily deformed material capable of retaining the deformed shape, said second member further including a portion of material having hook-forming pile threads, and said portion of material being fixed to said body, whereby the first member can be attached to a surface, the clamping portion of said second member can be deformed to clampingly engage said needle, and said body can be removably mounted on said first member by said hook-forming pile threads engaging the cloth-like material of said first member.
2. The structure of claim 1 in which said cloth-like material is of a fiuffy character.
3. The structure of claim 2 including means for protecting said adhesive means When not in use.
