DETAILED DESCRIPTION

(23) In the present detailed description, the word “arm” is defined as the entire arm, from the shoulder joint to the wrist, this including the upper arm and the forearm.

(24) The expression “shoulder complex” is defined as the acromioclavicular, sternoclavicular, glenohumeral and scapulothoracic joints, and their associated muscles and bones attached to the scapula.

(25) The patient arm support described herein and methods for using same relate to providing support to at least one arm during a surgical operation while minimizing undue pressure on the nerves and loss of blood flow in the arm.

(26) FIGS. 2 and 3 illustrate an exemplary patient arm support 30. The patient arm support 30 is shaped to receive the arm of a patient lying in a supine position during, for instance, an operation. In the supine position, the patient's arm may be resting on a patient arm support 30 on top of a lateral portion 22 of an operating table 20 (i.e. armboards) forming an angle of 90 degrees or less with the core portion of the operating table 20. The lateral portion 22 may be parallel with the floor. The lateral portion 22 may be level with the core portion 24 of the operating table 20. The core portion 24 of the operating table 20 may be defined as the portion of the operating table 20 receiving at least the trunk of the patient.

(27) Even though the patient arm support 30 may be used during a surgical procedure, the patient arm support 30 can also be used for any procedure or time when a person is to lie on his or her back for a prolonged period with limited to no movement. Such instances may be, for instance, during convalescence or when a patient is confined to bed for a prolonged time.

(28) In the case of a surgical operation during which the patient is anesthetized, the patient remains immobile which may result in growing pressure points at different locations on the patient's body. Such pressure points can lead to nerve damage. Therefore, the patient arm support 30 may be used to position the arm in a relaxed position while reducing pressure exerted on portions of the arm which may namely lead to nerve damage.

(29) During an operation, one patient arm support 30 may be used, or alternatively, two patient arm supports 30 may be used, where each of the patient arm supports 30 is used to support one of the patient's arms.

(30) The patient arm support 30 has a base 46 for resting on a surface such as an operating table 20. On the opposite side of the base, the patient arm support 30 has a resting surface 47 on which the patient's arm is placed and may rest. The patient arm support 30 also has a proximal end 48 and a distal end 49 opposite to the proximal end 48.

(31) The patient arm support 30 has a tapered portion 32 at the proximal end 48, a set of walls 36 and a groove 37. The patient arm support 30 also has an upper arm portion 31A, a forearm portion 34 and an elbow gap 31 shaped to receive an elbow, the elbow gap 31 located between the upper arm portion 31A and the forearm portion 34. The patient arm support 30 may also have a wrist region 42 and a hand portion 33 near the distal end 49. The hand portion 33 may also have an upward curved portion 43.

(32) As shown in FIG. 3, the patient arm support 30 has a groove 37 for receiving at least a portion of the patient's arm. The groove is a space on the top surface of the patient arm support 30, on which the patient's arm is to be placed. The groove 37 may extend across the upper arm portion 31A, the forearm portion 34 and optionally, the hand portion 33. The groove 37 is shaped to receive the patient's arm.

(33) The patient arm support 30 has a tapered portion 32 which rests under at least a part of the patient's shoulder complex 11. This tapered portion 32 is wedged between the shoulder complex 11 and the operating table 20. The tapered portion 32 may be wedge shaped, where the thinnest portion is placed between the patient's shoulder complex 11 and the surface on which the patient is resting (e.g. the operating table 20). The weight of at least a part of the shoulder complex 11 on the tapered portion 32 may provide anchoring of the patient arm support 30 to the operating table 20, as the weight of the body of the patient may hold the tapered portion 32 and the patient arm support 30 in place. The slope of the tapered portion 32 may be of a gentle upward incline in order to slightly elevate the patient's arm and reduce strain on the brachial plexus and the shoulder joint, including the muscles, tendons and nerves located in proximity to the shoulder joint, this incline illustrated for example by curve 51B (following the slope of the shoulder and shoulder complex 11) when compared with the flatter incline representing that of the shoulder and shoulder complex, as shown by curve 51A in the prior art FIG. 1A. This reduction in strain may also provide support to patients who are predisposed to shoulder dislocation, by reducing the strain applied to the shoulder when lying in a supine position. Furthermore, the upper surface of the tapered portion 32 on which rests the shoulder complex 11 may be slightly curved to cup and mold to the shoulder complex 11 and upper portion of the patient's back. In some embodiments, the tapered portion 32 may be shaped to fully extend across the full length of the shoulder complex 11. In other embodiments, the tapered portion 32 may be shaped to extend across only a portion of length of the patient's shoulder complex 11.

(34) The tapered portion 32 may also slightly lift the shoulder complex 11 above the operating table 20, where the tapered portion 32 rises slightly the shoulder complex 11 from the operating table 20. This rising of the shoulder complex 11 and the support provided by the patient arm support 30 to the upper arm 12 in turn may also result in reducing the downward angle of the upper arm 12. In FIG. 1A, the upper arm 12 naturally slopes downward as a result of the upper arm 12 and the shoulder complex 11 lying directly on the flat operating table 20. This positioning adds strain on the brachial plexus and the portion around the shoulder joint, such as the rotator cuff. Furthermore, the inclined position of the upper arm 12 may also add additional weight on the elbow, such as the weight of the arm on the elbow, which may result in applying undesired pressure on the ulnar nerve, increasing the risk of damage to this nerve as a result of compression. As shown in FIG. 2, by elevating the shoulder complex 11 slightly above the operating table 20 and by maintaining or only slightly reducing this elevation for the rest of the arm supported by the patient arm support 30, the upper arm 12 may also gently slope downward. However, the weight of the arm is supported and may be distributed along the upper arm portion 31A. This position may also reduce strain in the area around the shoulder joint. Second, as the upper arm's 12 downward slope is minimized, this position of the upper arm 12 may diminish the pressure caused by the arm to the elbow and the ulnar nerve, the weight of the upper arm 12 distributed along the padding of the upper arm portion 31A instead of focused towards the elbow region. This may limit the risk of injury to the ulnar nerve as a result of compression.

(35) Alternatively, and aside or in addition to the tapered portion 32 anchoring the patient arm support 30 in place, the patient arm support 30 may be held in place using a fastening means, such as a hook and loop fastener 57 like Velcro®, wherein a strip of the fastening means lies across the operating table 20, spanning from one lateral portion 22 to the other or at least across certain portions of each of the lateral portions 22, and where the complementary strip is found at the base of the arm patient support 30 for adhering to the strip found on the operating table. The fastening means would allow each patient arm support 30 to be placed at a designated location on the operating table 20, for limiting movement during the operation procedure, where the fastening means found on the patient arm support 30 may be joined at the desired location to the complementary portion of the fastening means running across the operating table where the patient's arms are to lie. For instance, the hook portion of the hook and loop fastening means may be joined to the base of the patient arm support 30 and the corresponding loop portion of the hook and loop fastening means may be joined to the lateral portion 22 of the operating table 20. Once the patient arm support 30 is properly positioned at a desired location to receive the patient's arm, then the hook portion and loop portion may be joined, holding the patient arm support 30 in place during the operation. In the case where two patient arm supports 30 are used (one for each arm), this would allow, for instance, for adjustment of the distance between each of the patient arm supports 30 in accordance with the proportions of the patient, such as the distance between each of the patient's shoulder complex 11. A skilled person will readily recognize that other forms of fastening may be used, such as an elastic strap or an adjustable strap 56 attached to the patient arm support 30 that may wrap around the lateral portion 22 of the operating table 20 and hold the patient arm support 30 in place, without departing from the present teachings. In other embodiments, the fastening means may be a series of snaps, where, for instance, a male part of the snap fastener is located on the base of the pillow and the female part of the snap fastener is located on, for example, the lateral portion 22 of the operating table 20. In another embodiment, the fastening means may be a sleeve, to which the patient arm support 30 is attached, where the sleeve is shaped to hug the contours of at least a portion of the lateral portion 22 of the operating table 20, the lateral portion 22 of the operating table 20 inserted into the sleeve. The sleeve may be of a stretchable or elastic material to provide a snug fit around the lateral portion 22.

(36) The patient arm support 30 may also have an upper arm portion 31A. The upper arm portion 31A receives the upper arm 12 of the patient. In some embodiments, the upper arm portion 31A may be parallel with the operating table 20. In other embodiments, the upper arm portion 31A may have a slight incline downward. In the embodiment of the patient arm support 30 where the upper arm portion 31A has a slight downward incline, when the patient's arm is resting in this exemplary embodiment of the patient arm support 30, the portion of the upper arm 12 nearer to the shoulder is slightly more elevated from the base 46 than the portion of the upper arm 12 located nearer to the elbow.

(37) In some embodiments, when a patient's arm and hand 14 is resting on an exemplary patient arm support 30, the patient's shoulder and the portion of the patient's upper arm 12 nearest to the shoulder may be approximately at the same height from the base 46 as the patient's hand 14. The hand portion 33, the portion of the forearm portion 34 nearer to the hand portion 33, and the portion of the upper arm portion 31A nearer the proximal end 48, may be near the same height so as to maintain blood flow in the hand 14 and the fingers of the hand 14 while the patient's arm and hand 14 are resting on a patient arm support 30.

(38) The patient arm support 30 has an elbow region 31 in the groove 37 for receiving the elbow of the patient's arm. The elbow region 31 may be a cavity and is shaped with a sufficient depth and width so as to accommodate the patient's elbow and minimize contact of the surface of the patient arm support 30 on the elbow which may lead to undesirable pressure during, for example, the course of a surgical operation. In some embodiments, the elbow region 31 is of such dimensions so that there is no contact between the elbow and the patient arm support 30 when the patient's arm is resting on the patient arm support 30. In some embodiments, the elbow region 31 may be of a half-moon shape, forming a half-moon indentation in the groove 37 of patient arm support 30. In other embodiments, the elbow region 31 may be, for example, of a rectangular prism shape. It may be appreciated that the elbow region 31 may be of any shape that creates sufficient spacing between the patient's elbow and the surface of the patient arm support 30, so as to limit and/or eliminate contact between the patient arm support 30 and the elbow. In some embodiments, the elbow region 31 may be filled with a very soft foam, where little to no pressure is applied by the foam to the elbow.

(39) Furthermore, the elbow region 31 may separate the upper arm portion 31A from the forearm portion 34.

(40) The patient arm support 30 may have an elbow marking 44 located on the outside surface 41 of the patient arm support 30. This elbow marking 44 may be in the form of an arrow, or a straight line, indicating to, for example, an orderly or nurse the location at which the patient's elbow is to be placed in the patient arm support 30. The elbow marking 44 is aligned with the elbow region 31. The elbow marking 44 may facilitate the positioning of the arm when preparing for a surgical operation, by assisting the surgical staff with the positioning of the patient arm support 30 so that the elbow is aligned with the elbow region 31, for protecting the ulnar nerve. Furthermore, for instance, in an embodiment of the patient arm support 30 where the walls 36 of the patient arm support 30 are opaque, and where the elbow region 31 may not be easily visible when adjusting the patient's arm in the patient arm support 30, the elbow marking 44 may allow for facilitating the alignment of the elbow with the elbow region 31 made to receive the elbow of the patient.

(41) The patient arm support 30 has a forearm portion 34. The forearm portion 34 is shaped to receive the forearm 13 of the patient. The forearm portion 34 may have a slight upward incline, as such that when the patient's arm is resting in the patient arm support 30, the portion of the patient's forearm 13 located nearer to the elbow is lower with respect to the base 46 than the portion of the patient's forearm 13 located nearer to the wrist. A person skilled in the art will readily recognize that the angle of this incline may vary without departing from the present teachings.

(42) The patient arm support 30 also has a hand portion 33 for receiving the entire hand 14 of the patient. This hand portion 33 may also be inclined, where, in some embodiments, the incline of the hand portion 33 may be the same as that of the forearm portion 34. In other embodiments, the incline of the hand portion 33 may be greater or lesser than that of the forearm portion 34. The slight upward inclined of the hand portion 33 may reduce a strain applied to patient's wrist and to the median nerve which would have otherwise resulted from the over extension of the wrist. When the patient is resting on the patient arm support 30, the patient's arm and hand may be placed in the supination position or the neutral position.

(43) Optionally, the hand portion 33 may be shaped in such a way as to allow the fingers of a patient, when the fingers are resting on the hand portion 33, to remain curved slightly upwards while resting on an upward curved portion 43 of the hand portion 33. The upward curved portion 43 may be placed at the furthest region of the hand portion 33 with respect to the tapered portion 32 and has a slight upward curve.

(44) Optionally, there may be a wrist region 42 for receiving the wrist of the patient, extending from the patient's arm. The wrist region 42 may be of a soft foam material for minimizing pressure to the wrist or may be an empty cavity. The wrist region 42 may be located between the forearm portion 34 and the upper hand portion 33. The wrist region 42 is shaped with a sufficient depth and width so as to accommodate the patient's wrist and minimize over extension of the wrist, which may prevent, for instance, compression of the median nerve. In some embodiments, the wrist region 42 may be of a half-moon shape, creating a half-moon indentation in the patient arm support 30. In other embodiments, the wrist region 42 may be a shallow concavity in the surface of the groove 37. However, it will be appreciated that the wrist region 42 may be of any shape that creates sufficient spacing between the patient's wrist and the surface of the patient arm support 30, so as to limit and/or eliminate contact between the patient arm support 30 and the wrist.

(45) The patient arm support 30 may have a wrist marking 45 located on the outside surface 41 of the patient arm support 30. The wrist marking 45 may be in the form of an arrow, or a straight line, for indicating to, for example, an orderly or nurse the location at which the patient's wrist is to be placed in the patient arm support 30. The wrist marking 45 is aligned with the wrist region 42. The wrist marking 45 may facilitate the positioning of the patient arm support 30 when preparing for a surgical operation for aligning the wrist region 42 with the wrist. Furthermore, in some embodiments of the patient arm support 30 where the walls 36 of the patient arm support 30 are opaque, and where the wrist region 42 may not be easily visible when adjusting the patient's arm in the patient arm support 30, the wrist marking 45 allows for facilitating the alignment of the wrist region 42 made to receive the wrist of the patient with the wrist.

(46) As shown in FIG. 3, the patient arm support 30 may have two walls 36, one on each side of the patient arm support 30. Each of the walls 36 is also located on either side of the groove 37. The walls 36 secure the patient's arm when resting in the patient arm support 30. The walls 36 may also prevent the patient's arm from falling off of the operating table 20 when the patient's surgical position is changed during the course of an operation by securing the arm within the patient arm support 30. The inside portion of each of the walls 36 forms a curved surface with the groove 37 for receiving the patient's arm. The groove 37 may also prevent the patient's arm from falling from the patient arm support 30.

(47) In some embodiments, the patient arm support does not have a groove 37 or walls 36. Instead, the patient's arm may be secured to the patient arm support using a strap passing around the patient's arm. This strap may also prevent the patient's arm from falling during the course of the operation.

(48) In some embodiments, as shown in FIG. 9A to 9F, the patient arm support 30 may have at least one wall 36B that spans only part of the length of the patient arm support 30. The partial wall 36B may allow for the patient's arm to be easily placed in the patient arm support 30. Wall 36A and wall 36B assist with securing the arm in the groove of the patient arm support 30. Partial wall 30B may be found on the side of the patient arm support 30 that will be facing the feet of the patient when the patient is placed in a supine position on an operating table, and the patient's arm is positioned in the patient arm support 30. The wall 36A may span a greater length of the patient arm support 30. In some embodiments, wall 36A may span the full length of the patient arm support 30. It will be understood that in the embodiments of the patient arm support 30 that include a wall 36A and a wall 36B, the patient arm support 30 may be adapted for a right arm or for a left arm such that the wall 36B is positioned on the patient arm support 30 such that wall 36B is facing the feet of the patient when the patient's arm is placed in the patient arm support 30 and the patient is in a supine position on an operating table.

(49) In one embodiment, the patient arm support 30 may be dimensioned in such a way so as to accommodate the arm of a large male patient. The dimensions in one example may b as follows: the length of the patient arm support 30 may be 32 inches for accommodating the arm of a large male, and the width of the patient arm support 30, measured from the outside portions of the walls 36, may be 6.75 inches. The height of the patient arm support 30 at the distal end 49, measured perpendicularly from the base 46, may be of 3.9 inches. The dimensions of the patient arm support 30 may be configurable in order to adjust to the arm length and proportions of the patient. In some examples, the different patient arm supports 30 may be available in different standard sizes for accommodating different sized patients (e.g. a size for children, a size for average size adults and a size for tall adults). In an alternative embodiment, each of these standard models of the patient arm support 30 may be provided with an adjustable feature, where the patient arm support 30 may be slightly stretched or adjusted in order to match the proportions of the patient's arm.

(50) In an alternative embodiment, as shown in FIG. 4, an exemplary patient arm support 30 may comprise air pockets 38 for massaging the patient's arm as an air pump circulates air through these pockets. This massaging may also remove, reduce or redirect pressure exerted on the arm and its nerves resulting from contact between the arm and the patient arm support 30, and may promote circulation in the arm. In an exemplary embodiment, the patient arm support 30 may be composed of two layers. A first, underlying mold-layer 39A may be shaped to define the different air pockets ranging across the patient arm support 30 for massaging. A second, overlaying layer 39B, placed on top of the mold layer 39A, making contact with the mold layer 39A and which may result in a partial seal between the two layers 39A and 39B, where the pockets 38 in which air may be pumped and circulated are sealed, creating passageways for the air. As pressure increases in the pockets 38 as a result of the air pump, the air exerts a force upon the overlaying layer 39B, this force causing the layer 39B to stretch and release, this change in the layer 39B massaging the patient's arm. In another embodiment, the patient arm support 30 may be composed of a single material, the pockets 38 present within the patient arm support 30. Furthermore, in alternative embodiments, massaging may be provided instead by a motor mechanism, the motor creating for instance slight undulations or vibrations in the material on which the patient's arm is resting.

(51) The outer surface of the patient arm support 30 may be composed of a soft, flexible material for cushioning the patient's arm. In some embodiments, the patient arm support 30 may be made of inert, latex-free and/or fireproof materials. The patient arm support 30 may be composed of hypoallergenic material in order to reduce the probability of an allergic reaction resulting from, for instance, the patient's skin reacting to the material. In some embodiments, the patient arm support may be made out of a soft two-component platinum silicone casting foam, such as the foam Soma Foama® of Smooth-On Inc.

(52) FIG. 5A shows a model of a patient lying on the operating table 20, where both of the patient's arms are resting in their own respective exemplary patient arm supports 30. For each of the patient arm supports 30, the entire length of the arms as well as the entire hand is received by the patient arm support 30. The tapered portion 32 is positioned under the patient's shoulder complex and may be anchored in place by the weight of the patient applied onto the tapered portion 32 of the patient arm support 30. As shown in FIG. 5A, a length of the tapered wedge portion 32 is orthogonal with the length of the patient's body when lying on the operating table 20.

(53) As shown in FIG. 5B, the tapered portion 32 may extend fully across the patient's shoulder complex, providing anchorage of the patient arm support 30 to the operating table by the patient's upper body, and provide a gentle steady incline away from the proximal end 48, where the patient's shoulder complex and elbow are slightly lifted, resulting in less pressure on the brachial plexus and the shoulder joint.

(54) FIG. 6 shows an exemplary method 50 for positioning a patient's arm on a patient arm support 30 during a surgical operation. First, the patient arm support 30 is positioned on the operating table at step 51. When two of the patient arm supports 30 are used, the distance between both patient arm supports 30 should be such that the tapered portion 32 of each of the patient arm supports 30 may accommodate the shoulder complex 11 of a patient lying in the supine position. In some embodiments, when two patient arm supports 30 are placed one facing the other in order to receive each of the patient's arms, each of the tapered portions 32 of the patient arm supports 30 may be shaped so that one tapered portion 32 may be tucked under the other tapered portion 32 in order to adjust the patient arm support 30 to the length of the patient's arm(s). The patient arm support 30 is positioned on the operating table so as to receive the arm of the patient resting in a supine position. The patient arm support 30 may thus be placed on the lateral portion 22 of the operating table.

(55) Optionally, the patient arm support 30 may be secured in place onto the operating table 20 using a fastening means as described herein.

(56) The patient is laid down onto the operating table 20 in the supine position and the shoulder complex 11 of the patient is positioned over the tapered portion 32 of the patient arm support 30 at step 52. The weight of the patient, exerted on the tapered portion 32 of the patient arm support 30 and wedging the tapered portion 32 against the operating table 20, may secure the patient arm support 30 in place.

(57) The patient's arm, or at least a portion of the patient's arm, is then placed in the groove 37 of the patient arm support 30 at step 53. Optionally, size adjustments of the patient arm support 30 may be made in order to accommodate different arm lengths and proportions.

(58) The arm is positioned in such a manner so as to not over-extend or cause undue extension or flexion at the level of the joints, in a supine position. When placing the arm in the patient arm support 30, the patient arm support 30 is adjusted so that the elbow is positioned in the elbow region 31 of the groove 37 at step 54A. This positioning may reduce pressure exerted by the surface of the patient arm support 30 on the elbow and the ulnar nerve during the operation. Optionally, when the patient arm support 30 has an elbow marking 44 on its exterior marking the location of the elbow region 31 in the groove 37, the elbow marking 44 is aligned with the patient's elbow so that the elbow is positioned in the elbow region 31 at step 54B.

(59) The patient's hand 14 may then be placed on the hand portion 33 of the patient arm support 30, where the palms may be facing up, at step 55A. The hand support 33 may accommodate the entire hand 14 of the patient. An upward curved portion 43 of the hand support 33 may be shaped in order to allow the fingers of the patient's hand 14 to rest in a position where the fingers are curled slightly upward.

(60) Optionally, when the patient arm support 30 has a wrist region 42 and a wrist marking 45 indicating the position of the wrist region 42 in the groove 37, the patient's wrist may be aligned with the wrist marking at step 55B. As such, the patient's wrist is positioned in the wrist region 42.

(61) Optionally, the arm resting in the patient arm support 30 may be massaged using a massaging mechanism, such as an air pump flowing through cavities positioned under the surface on which the arm is resting.

(62) The description of the present invention has been presented for purposes of illustration but is not intended to be exhaustive or limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art.
