Further, for ease of discussion, the present invention is discussed in connection with infants and lumbar puncture procedures, however the instant device can be used with patients of any age or size and for any number of medical, or non-medical, procedures.

(13) The present invention provides new and novel infant stabilizer devices that can repeatably maintain an infant, or patient of any age, in the proper position during a medical procedure, such as a lumbar puncture, while permitting unimpeded ventilation and breathing for the infant.

(14) In one exemplary embodiment, the present disclosure is directed to an infant positioning device 100 for stabilizing and maintaining an infant 110 in a fixed position for a lumbar puncture procedure. The device 100 can consist of a frame 120 with openings 125, 126 for the infant's face and abdomen to support the infant 110 in the proper position for the procedure and allow for unimpeded ventilation, to ensure that the infant can breathe properly during the procedure. Further, a component of the frame can be provided to secure and stabilize the infant within the frame to prevent movement during the procedure. Moreover, the device can include a stand attachment 130 to the frame that allows the frame to be free-standing.

(15) In a first embodiment, as shown in FIGS. 1-5, an infant positioning stabilizer is provided. The infant positioning stabilizer 100 can stabilize and maintain an infant 110 in a fixed position during a medical procedure. As noted above, one such medical procedure is a lumbar puncture. During the lumbar puncture procedure, it is imperative that the infant 110 is secured in a fixed fashion so that they do not move. Such movements can compromise the results of the test or cause injury to the infant. In general, the device 100 includes a frame 120 for positioning the infant 110 in the appropriate position and a stand attachment 130 for allowing the frame 120 to be self-standing and to be oriented at an angle appropriate to the medical procedure being performed. The attachment stand, attachment, or stand, 130 can be mounted or otherwise connected at an appropriate angle relative to the frame 120 to enable the device 100 to stabilize and maintain the infant 110 in the appropriate position throughout the duration of a medical procedure.

(16) The attachment stand 130 can preferably be in the form of a stand that is secured to the frame 120 by fasteners (not shown), and the like. The attachment 130 can be formed of metal, or other rigid materials, in a generally “U” shape. The ends 131a, 131b of the attachment 130, can be formed as a generally triangular shape that can serve as anchor points 132a, 132b to be inserted into slots 122a, 122b on a rear side 121r of the upper portion 121 of the frame 120. The attachment 130 can be angularly adjustable, relative to the frame 120, within the slots 122a, 122b, to permit the angle of the frame 120 to be adjusted for a given procedure. Additionally, or alternatively, the attachment stand 130 may be selectively angularly locked relative to the frame 120. In a further alternative the attachment stand 130 may also be integrally formed with the frame 120.

(17) The frame 120 can, advantageously, be designed to provide both ergonomic comfort and proper positioning for the infant 110, as shown in at least FIG. 4. As can also be seen in FIGS. 1-3, the frame 120 can generally include a bottom portion 123 that has a generally bowl shape, including two leg cut outs 124a, 124b and an abdomen opening 125. Extending upward from a front 123f of the bottom portion can be a stop 127 that can prevent the infant 110 from sliding backward out of the bottom portion 123. Additionally, or alternatively, extending upward from a rear 123r of the bottom portion 123 can be the upper portion 121 of the frame 120. Similar to the bottom portion 123, the upper portion 121 can have a “U” shaped cross-section to ergonomically cradle the infant's head 112 and shoulders/torso 116 and a corresponding facial opening 126 to allow the infant's face 114 to be exposed to allow for unimpeded breathing. In the illustrated embodiment, the frame 120 is an integral assembly where the upper and bottom portions 121, 123 are formed as a single piece. The frame 120 can be formed of a variety of materials including rigid plastics, or other materials which can be sterilized. In some embodiments, the frame 120 can include padding on a front face to provide additional comfort to the infant 110 being strapped to the frame.

(18) In some embodiments, as shown in FIG. 5, the device 100 may employ an upper strap 140 and a lower strap 142. The straps 140, 142 can have one side made of a soft material which can be secured for example by hook and loop fasteners 144a, 144b, 146a, 146b. The fasteners 144 a,b, 146 a,b, are placed on the rear of the upper portion 121 to allow for adjustable attachment of the straps 140, 142. As shown in FIG. 5, the upper strap 140 can be used to secure the head 112 of the infant 110 and the lower strap 142 can be used to secure the infant's torso 116. Of note, in FIG. 5, the attachment stand 130 is removed for ease of illustration purposes only.

(19) In one exemplary method of use, as shown in FIGS. 4 and 5, the infant 110 can be placed to face forward into the frame 120 that is supported at a desired angle by the attachment stand 130. The infant 110 can be positioned so that the openings 125, 126 in the frame 120 are aligned with the face 114 and abdomen 117 to ensure the infant's face 114 and abdomen 117 are appropriately situated, as best seen in FIGS. 4 and 5. Once the infant 110 is in the desired position, as in FIG. 5, the straps 140, 142 can be secured in place. The infant 110 is thus stabilized, using the attachment(s) to the frame to ensure minimal movement of the infant's head 112 and body, or torso, 116. The frame component 120 along with the attachment stand 130 achieves the desired angle to the ground for a procedure, such as a lumbar puncture, and to ensure that the frame 120 is self-standing during the lumbar puncture.

(20) A second embodiment of a self-standing infant stabilizer device 200 is shown in FIGS. 6-11. The second embodiment 200 provides for a larger number of adjustments for the device to accommodate a larger number of sizes of infants. In the illustrate embodiment, the frame, or static frame, 220 can include an upper and lower frame portions 221, 223 and a slide frame 250 which is a separate part that can slide relative to the frame 220. Additionally, the device 200 can include slidable straps 240a, 240b, 242a, 242b which can vertically slide relative to the slide frame 250. Thus, the device 200 can provide for added adjustments as compared to the single use size of the device 100.

(21) The frame 220 of the device 200 can, like the device 100 above, cradle and support an infant for a variety of medical procedures, including a lumbar puncture. The infant 110 is placed on the frame 220 in similar fashion to frame 120 of the first embodiment 100 of the present invention. The frame 220 can be made of various materials include of plastics or metals that can be easily and quickly sanitized for multiple uses. The frame 220 can be a single unitary piece made from a single piece of material. The lower frame portion 223 can have a generally bowl shape including an upper backing or stop 227 extending from the front 223f of the device 200 to prevent the infant from sliding out. At the rear 223r of the frame 220, the lower frame portion 223 can have two leg cut outs 242a, 242b sized to receive the legs of the infant. The frame 220 can additionally include an abdomen opening 225 that allows for the infant to breath regularly. Extending up from above the abdomen opening can be an upper u-shaped frame 221.

(22) As best seen in FIG. 8, the upper U-shaped frame 221 can include a first and second uprights 222a, 222b that define a facial opening 226. The facial opening 226 can provide for a place for the infant's face to be located to provide a clear breathing airway. On a rear face of the first and second uprights 222a, 222b anchor points 228a, 228b for attachment stand 230 can be disposed and will be discussed in detail below with respect to the attachment stand 230. The first and second uprights 222a, 222b can additionally include respective grooves 229a, 229b, below the respective anchor point 228a, 228b. The respective grooves 229a, 229b that are obround, or stadium, in shape and can be sized to slidably receive a compression screw and knob 260a, 260b extending therethrough to slidably secure the slide frame 250. The length of the grooves 229a, 229b define the amount of vertical adjustment the slide frame 250 can move relative to the frame 222. The compression screws 260a, 260b can be received in a respective threaded through hole 262a, 262b on the rear of the slide frame 250, as shown in FIG. 11.

(23) As illustrated in FIGS. 6 and 7, the slide frame 250 is designed to be vertically adjustable relative to the frame 220 to accommodate children of a variety of sizes. Advantageously, with an adjustable stabilizer device 200, precious storage room can be saved as a plurality of sized stabilizers in a plurality of sizes are not required. In addition, or alternative, to the slide frame 250 being vertically adjustable, the two sets of straps 240a, 240b, 242a, 242b can be vertically adjustable relative to the slide frame 250 and the other of the straps. Thus, due to the adjustability of the slide frame 250 and the straps 240a, 240b, 242a, 242b, the overall device 200 can accommodate infants of various sizes, body shapes, and other medical considerations (e.g. a problematically placed port or sensors).

(24) As seen in FIG. 11, the slide frame 250 can be of a rectangular shape with rounded corners having a corresponding U-Shape in cross section to match the upper portion 221 of the frame 220. The slide frame 250 is designed to sit and ride on the front face 221f of the upper frame portion 221 and is retained to the upper frame by the compression screws with knobs 260a, 260b being received in respective threaded through holes 262a, 262b. The compression screws 260a, 260b can be inserted from the rear of the upper frame 212 through respective slots 229a,b into the threaded through holes 262a, 262b of the slide frame 250. Once the desired height is reached the knobs 260a, 260b can be turned to tighten and thus fix the slide frame 250 relative to the upper frame 212. Similar to the upper frame 212, the slide frame 250 can include a facial opening 256 to permit easy breathing for the infant.

(25) Referring back to FIGS. 6 and 7, in order to retain the infant in the device 200, two sets of straps 240a, 240b, 242a, 242b, or more, can be provided to secure the infants head and the infants torso. In some embodiments, as shown in FIGS. 1-5, the straps can be fixed relative the frame 220. In the illustrated embodiment of FIGS. 6-11, an upper set of slots 252a, 252b and a lower set of slots 254a, 254b on the left and right edges 251a, 251b of the slide frame 250 are provided to allow the straps 240a, 240b, 242a, 242b to be vertically adjusted for the proper height of the child. The upper left and right straps 240a, 240b can each have a distal end with a retaining plate 241a, (only one side is shown) having a through hole (not shown) to receive a compression screw 244a. The upper compression screws 244a can be inserted from the rear of the slide frame 250 into the respective retaining plate 241a and slid up or down within the respective slot 252a, 252b. While only one side of the compression screws 244a and plates 241a are shown, one of ordinary skill in the art will understand that the opposite strap has the same structure. When the respective compression screws 244a are tightened, they can fix the respective plate 241a and thus the strap 240a, 240b at a given height. The compression fit fixes the plate 241a and thus the strap 240a, 240b at the chosen height. In the illustrated embodiment, a respective plate 241a can be located on the back of the slide frame 250 and a respective cap 253a, 253b can be inserted from the front to cover the compression screw 244a to prevent any injury to the infant. In some embodiments, as illustrated, the straps 240a, 240b can be cushioned on a rear face to provide comfort to the child and can be fastened to one another via hook and loop fasteners, or similar mechanical or magnetic fasteners (not shown).

(26) The lower straps 242a, 242b can be substantially the same as the upper straps with the inclusion of included cushion pads 247a, 247b to cushion around the infant's torso and outer plates 248a that are larger to retain the straps shape around the torso when loading the infant into the device. The lower left and right straps 242a, 242b can each have a distal end with a retaining plate 243a (only one is shown) having a through hole (not shown) to receive a compression screw 246a (only one is shown). The respective lower compression screws 246a can be inserted from the rear of the slide frame 250 into the respective retaining plate 243a and slid up or down within the respective slot 254a, 254b. When the respective compression screws 246a are tightened, they can fix the respective lower plate 243a and thus the lower straps 242a, 242b at a given height. The compression fit fixes the plate 243a and thus the strap 242a, 242b at the chosen height. In the illustrated embodiment, a respective plate 243a can be located on the back of the slide frame 250 and a respective cap 255a, 255b can be inserted from the front to cover the compression screw 246a to prevent any injury to the infant. In some embodiments, the straps 242a, 242b can be fastened to one another via hook and loop fasteners, or similar mechanical or magnetic fasteners (not shown).

(27) In some embodiments, the attachment stand 230 can be substantially the same as the attachment stand above. Alternatively, as shown in the illustrated embodiment, the attachment stand 230 can be a modified “U” shaped stand with two plastic support feet 270a, 270b. The modified “U” shaped frame can include a central base portion 231 having two legs 232a, 232b extending rearwardly and outward (relative to a line that extends perpendicular to the central base portion). Each of the legs includes upright supports 234a, 234b that extend forward and inward towards a distal end. The attachment stand 230 can be formed with a cylindrical cross section and the distal ends can be received in anchor holes on the upper frame. At the bend point 233a, 233b from the central base portion to the two respective legs 232a, 232b, the assembly can include plastic support feet 270 that include an internal channel for receiving the stand. The support feet 270 can provide for added stabilization, thought they are not required. Additionally, or alternatively, the lower portion 223 of the frame can include two offset projections 224a, 224b and a channel 224c extending therebetween to capture a portion of the central base portion 231 where the lower portion 223 rests thereon.

(28) In use, as in FIGS. 6 and 7, an infant can be placed in the device 200 before or after the adjustment of the device. The knobs 260a, 260b for the slide frame 250 can be loosened, but not removed, to allow the slide frame 250 to be adjusted up or down, as needed, relative to the frame 200. Once the slide frame 250 is in the appropriate location the knobs 260a, 260b can be turned in the opposite direction to lock the slide frame 250 in place. Similarly, one or both sets of straps 240a, 240b, 242a, 242b, or just one strap, can be adjusted by rotating the respective knob clockwise, or counterclockwise, to loosen the connection and allow for sliding movement through the respective slots up or down. Again, once the desired location in the slot is achieved, the respective knob can be tightened to secure the location of the strap 240a, 240b, 242a, 242b relative to the slide frame 250 and the frame 220. Once the adjustments are complete, a user can place the infant, face first, into the device 200. The user will ensure that the infant's face is disposed in the openings 226, 256 and the abdomen is disposed in the abdomen opening 225, all to ensure that the infant's ability to breath is not hindered. The user can then use the upper straps 240a, 240b to retain the infant's head and the lower straps 242a, 242b to retain the infant's torso. Once secured to the device 200, the medical procedure can begin with the infant being held still during the lumbar puncture, for example, to eliminate human error and to optimize the success of the procedure. Advantageously, the instant devices 100, 200 can improve the rates of non-traumatic lumber punctures while maintaining the infant's ability to breath comfortably—thus maintaining the infant in a secure upright position which has been shown to be better positioning for maximal width of spinal fluid column. These advantages during the procedure can lead to lower costs and shorter hospital stays.

(29) It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered by the appended claims.
