(17) Thus two embodiments, i.e. armboard 1 and armboard 10, of the same invention are presented. The armboard 1 is intended for deployment under the mattress of a procedure table on which a patient lies such that the arm platform 3 is located on the right side of the mattress to support the patient's right arm. Deployment of a right-side-only version, which is shown in the Figures, permits placing the base 2 under the mattress only on the right side the table. A left-side-only version, a mirror of the right-side-only version, permits placing the armboard 1 only on the left side of the table. The armboard 10, a dual-side version, is also intended for deployment under the mattress of a procedure table on which a patient lies, but the symmetrical shape of the base 12 and arm platform 13 enables the armboard 10 to be deployed on either side of the procedure table to support either the patient's right arm or left arm; deployment for the left arm support involves placing the base 12 under the mattress on the left side the table. Other features of the armboards 1 and 10 are intended to be the same, particularly including the presence of a height A, an angle B and the removable connectability with the wrist support 20 enabled by the slots 7 and 17 and the connector 24, this removable connectability having identical operation for both embodiments, i.e. for both armboard 1 and armboard 10.
(18) To removably connect the wrist support 20 to the armboard 1 (or armboard 10), the wrist support 20 is first attached to the patient and after clinical preparation the patient's arm, palm facing up, is placed generally onto the distal portion of the arm platform 3. Thusly placed, the connector 24, or hook-shaped connector element, may be inserted into slot 7, or slot element, to removably connect wrist support 20 to arm platform 1. To make such insertion, the hand 42 and attached wrist support 20 are moved so that the connector 24 is positioned medial, i.e. to the left (from the patient's perspective) of the slot 7. The operator then presses gently down while moving the hand 42 in the lateral direction, i.e. to the right until the bottom surface of the hook tip 28 drops into the slot 7. Said bottom surface may be rounded to make such slidable movement easy. The angled side 26 then engages with the medial, i.e. left, edge of the slot 7 and rides downward on said edge, the force exerted by the operator guiding the connector 24 laterally and downwards until: i) the front edge 30 of the wrist support 20 engages with the top surface of the arm platform 3, ii) the top surface of the hook tip 28 engages with the bottom surface of the arm platform 3 adjacent the lateral i.e. right edge of slot 7, and iii) the interior hook 27 engages with the lateral edge of slot 7. Thus the connector 24 captures the top and bottom surfaces of the arm platform 3 and the lateral edge of slot 7; since distance C is similar to the thickness of the portions of arm platform 3 adjacent the lateral edge of slot 7, a secure removable connection of wrist support 20 to armboard 1 is achieved. Where said thickness is the same as or greater than the distance C, such fit shall be snugly achieved, in particular where the material of the connector 24 permits slight vertical deflection of the hook tip 28 during engagement with arm platform 3. Therefore this embodiment includes two elements of an integral connection means, a generally hook shaped connector element, or connector 24, and a slot element, or slot 7.
(19) To detach the wrist support 20 from the armboard 1, the operator pushes the hand 42 in the medial direction, i.e. to the left or towards the patient's body. The wrist support 20 and connector 24 move in the medial direction only in the horizontal plane until the angled side 26 engages with the medial edge of slot 7 at which time the pushing force in the medial direction causes the connector 24, and therefore the entire wrist support 20 and attached hand 42, to also move in the vertical plane, i.e. upwards, as the angled side 26 rides over the medial edge of slot 7. Said pushing force simultaneously causes the top surface of the hook lip 28 and interior hook 27 to disengage from the bottom surface of arm platform 3 and lateral edge of slot 7, respectively. The operator continues to push on the hand 42 in the medial direction until the bottom surface of the hook tip 28 rides over the medial edge of slot 7 and onto the top surface of arm platform 3 medial to the slot 7, sliding easily because of the rounded feature of the bottom surface of the hook tip 28. The wrist support 20 is thusly detached from the armboard 1. Such removable connection of the wrist support 20 to the armboard 1 or armboard 10 enables the operator to release the patient's hand 42 from a supine position, thereby allowing it to pronate while still immobilizing the wrist 41 and hand 42; because the operator need only push to detach the wrist support 20 from the armboard 1 or 10, such detachment may be performed at any time following commencement of the procedure even when the wrist 41 and hand 42 are covered by a sterile drape.
(20) Although these embodiments, i.e. armboard 1 and armboard 10, demonstrate an integral connection means comprising a generally hook-shaped connector 24 on the wrist support device 20 removably engaging in a slot 7 or 17 on the armboards 1 or 10, many other types of similarly removable integral connection means, comprising at least one element of such connection means located on each of the armboards 1 and 10, and wrist support 20, can be envisioned by those skilled in the art. These include any of the following taken singly or in combination and apply to configurations including the wrist support 20 and both the armboard 1 and armboard 10: a ball and socket connection, with the ball on the wrist support 20 and socket on the armboard 1 or vice versa, alternatively with one or both of these elements placed in multiple locations on the arm platform 3 or 13 of the armboard 1 or 10; a peg and notch connection, with one element on the wrist support 20 and the other on the armboard 1; a hook or knob or other protrusion on the wrist support 20 and a rail with detents or notches or holes in which the hook or knob or other protrusion would fit on the armboard 1; a hook or knob or other protrusion on the wrist support 20 and one or more holes or indents in which the hook or knob or other protrusion would fit on the armboard 1 or 10; a clasp, hook or knob or key or other protrusion on the wrist support 20 that mates with a groove or slot or keyhole on the armboard 1; a releasable clamp on the wrist support 20 that engages with an edge or slot or rail or tab located on the armboard 1; a releasable clamp on the armboard 1 that engages with an edge or slot or rail or tab located on the wrist support 20; a suction cup located on the wrist support 20 that can be removably adhered to a surface of the armboard 1; a strap attached to wrist support 20 that secures into one or more holes or slots or notches on armboard 1 or that wraps around the arm platform 3 or 13.
(21) The armboard 1 or 10 and wrist support 20 may be composed of any rigid material including more particularly a non-magnetic material generally transparent to ionizing radiation, including x-rays, i.e. having a radiolucent property. Such transparency enables x-ray visualization of the vessels in the forearm 40 and wrist 41 during a radial access procedure, more particularly the radial artery and vessels adjacent the radial artery, in the event that such visualization is required to successfully access other vessels via the radial artery, a not-uncommon requirement particularly for those clinicians new to radial access. The material of the armboards 1 or 10 may also be transparent in the visible light spectrum and fabricated of multiple layers or in a single layer, for example cut and formed from a sheet of transparent, rigid, radiolucent plastic such as acrylic, polycarbonate or polyethylene.
(22) Dimensions generally described herein apply to both the armboard 1 and armboard 10. Unless the meaning is clearly to the contrary, all ranges set forth herein are deemed to be inclusive of the endpoints. Certain dimensions of the arm platforms 3 and 13 are generally selected from the range of fifteen to sixty inches long, and from the range of three to twelve inches wide. Certain dimensions of the bases 2 and 12, in a generally rectangular shape, are generally selected from the range of three inches to thirty inches on each side, or in a generally circular shape from the range of four to forty inches in its diameter. The height A is a certain dimension generally selected from the range of 0.25 inches to six inches. Certain dimensions of the wrist support 20 are generally selected from the ranges of three to twenty inches long and two to eight inches wide. The thickness of the armboards 1 and 10 is generally similar to the distance C and may generally be in the range of 0.005 inches to two inches, the armboards 1 and 10 having no requirement that said thickness be uniform across all of its surface. Distance C may therefore also generally be selected from the range of 0.005 inches to two inches. The slots 7 and 17 have a width as measured from the inner most edges that is selected from the range of 0.1 inch to two inches, and a length that is selected from the range of 3 inches to 30 inches, the length for the purpose of accommodating patients of varying size and the width for the purpose of engaging with a connector 24. Armboards 1 and 10 both show a device that has all of these dimensions fixed, i.e. non-changeable by a user; it is within the scope of this invention that for other embodiments some of these dimensions may be adjusted by the user, for example, by having instead of a unitary construction, a multi-part adjustable construction that permits the height A or the length of the arm platforms 3 or 13 to be changed by the user.
(23) Angle B, an optional feature, raises the lateral edge of the arm platform 3 relative to its medial edge (i.e. the edge adjoining the vertical member 8) by an angle selected from the range of 0.1 to 50.0. This has the effect, when the wrist support 20 is attached to the hand 42 and to the arm platform 3, of placing the hand 42 in a partially pronated position without having the wrist support 20 detached from the armboard 1. Although not specifically shown in the Figures, Angle B may also be present in armboard 10. Angle B is shown and described as fixed, i.e. non-changeable by an operator, however, by having instead of a unitary construction, a multi-part adjustable construction that includes a hinge between the arm platform 3 and the vertical wall 8, and a manual fixation means to fix the arm platform 3 in place following such adjustment, the angle B may be changed by an operator and such attribute is within the scope of this invention.
(24) A method of use of the present invention comprises the following general steps that include actions, in serial order, previously described in the background and specification sections herein; such steps apply to both the armboard 1 and armboard 10: i) the wrist support 20 is removably attached to the patient's forearm 40, wrist 41 and hand 42; ii) the wrist support 20 is then removably attached to the armboard 1 by placing the connector 24 into the slot 7; iii) the site on the forearm 40, wrist 41 or hand 42 are prepared in accordance with the type of medical procedure to be performed. The method of use may optionally further include: iv) removal of the wrist support 20 from the armboard 1 during or after completion of the medical procedure; v) post-procedure cleansing of the site on the forearm 40, wrist 41 or hand 42; vi) transport of the patient to a recovery area with the wrist support continuing to be attached to the forearm 40, wrist 41 or hand 42 and remaining in place for an extended period of minutes or hours after the completion of said procedure, to facilitate any healing process of the site, for example, hemostasis of a vascular puncture site.
(25) It will be understood that the present invention is not limited to the method or detail of construction, fabrication, material, application or use described and illustrated herein. Indeed, any suitable variation of fabrication, use, or application is contemplated as art alternative embodiment, and thus is within the spirit and scope, of the invention.
(26) It is further intended that any other embodiments of the present invention that result from any changes in application or method of use or operation, configuration, shape, size, user-configurability, or material, which are not specified within the detailed written description or illustrations contained herein yet would be understood by one skilled in the art, are within the scope of the present invention.
(27) Finally, those of skill in the art will appreciate that the invented apparatus, system and method described and illustrated herein may be developed, manufactured and implemented in any of several different ways.
(28) Accordingly, while the present invention has been shown and described with reference to the foregoing embodiments of the invented apparatus, it will be apparent to those skilled in the art that other changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
