Description:
BRIEF DESCRIPTION OF THE INVENTION:

This infant's hypothermia bunting controls an infant's body temperature for hospital purposes, such as surgical operations. Loss of body heat during preparation for surgery produces adverse physiological effects which can be critical, particularly for premature infants. It is important that the body temperature of the infant be controlled efficiently and uniformly over the entire body of the infant.

Most prior art systems circulate water through plastic tube blankets or pads which are stiff and do not conform to the body, resulting in inefficient heat transfer and local hot and cold spots. These prior art systems that incorporate plastic blankets or pads are heavy and therefore preclude covering the front of the finfant's body leaving large exposed body surface areas and consequent loss of body heat. The prior art systems include fluid transport tubes sandwiched between two impermeable plastic plys, limiting sterilization and laundering. They are very uncomfortable, particularly to those areas of the infant's body that rest on body supporting surfaces. The impermeable construction limits breathing and evaporation of body moisture, adding to discomfort.

This infant's hypothermia garment comprises front and rear panels of stretch fabric. The panels are rectangular in shape and are joined at their sides and bottom edges. The upper edges are separable to provide an opening for receiving an infant's body into the envelope between the front and rear panels.

The bunting encloses the body of the infant from the neck down. Several fluid conveying tubes are attached to the inner surfaces of the panels by stitching or by an attachment method set forth in a co-pending application of the present inventor filed in close proximity to the filing date of the present application and identified as Rogers, Ezell, Eilers and Robbins Docket 16,484 entitled Method of Joining Tubes to Fabrics. The tubes extend longitudinally along the panels to permit and not interfere with lateral or circumferential expansion of the bunting to conform to the contour of the infant's body. Each tube consists of a supply pass and a return pass. The supply passes lead from inlet manifolds, and the return passes return to outlet manifolds. The manifolds are located in a pocket at the bottom of the bunting and are connected by tubes to a hyperthermia machine that circulates temperature-controlled fluid through the tubes. The supply passes and return passes are alternated to effect substantially uniform temperature distribution over the entire inner surfaces of the bunting.

Two longitudinal lines of snap fasteners are spaced inwardly of the side edges of the front and rear panels for adjustment of the width of the inner envelope of the bunting. Three lateral lines of snap fasteners are spaced upwardly from the lower edges of the front and rear panels to adjust the depth of the inner envelope. These snap fasteners thus vary the effective volume of the bunting so that it can be made to conform to different sizes and shapes of infant's bodies, with the stretch fabric material of the bunting providing further conformity to the contour of the infant's body.

A plastic liner has snap fasteners around its edges for releasable fastening to the inner surface of the rear panel to distribute the load and pressure created by the fluid conveying tubes. The panel is removable for sterilization of the panel and for sterilization and laundering of the bunting.

DETAILED DESCRIPTION oF THE INVENTION

This bunting 20 has a front panel 21 that is about 18 inches wide and 24 inches long and a rear panel 22 that is the same width as the front panel and is about 30 inches long. The foregoing lengths are exclusive of a bag at the lower end of the bunting to be described hereinafter. The front panel 21 has an upper edge 23 with a downwardly curved center 24 positioned where the neck of an infant within the bunting would be located, and has side edges 25 and 26. The rear panel 22 has an upper edge 27 that is about 6 inches above the upper edge 23 of the front panel and has side edges 28 and 29. The side edges 26 and 28 of the front and rear panels respectively are sewed to the front and rear cloth bindings 30 and 31 of a zipper 32. The zipper 32 has a separator start element 33 at its upper end and a slider 34 that can fully open the zipper 32 with the upper ends separated down to a cloth stop element 35 at the lower end of the zipper that is sewn to the front and rear panels 21 and 22.

The other side edges 25 and 29 of the front and rear panels respectively are similarly sewn to the front and the rear cloth bindings 39 and 40 of a zipper 41. The zipper 41 has a separator start element 42 at its upper end and a slider 43 that can open the zipper 41 with the separator element 42 separated and the zipper 41 separated all the way down to a cloth stop element 44 that is sewn to the front and rear panels 21 and 22 at the lower end of the zipper 41.

A zipper 48 extends longitudinally along the center of the front panel 21. The side cloth bindings 49 and 50 of the zipper 48 are sewn to the front panel 21. The zipper 48 has a separator start element 51 at its upper end. A slider 52 can open the zipper 48 with the separator element 51 separated and the zipper 48 separated all the way down to a cloth stop element 53 sewn to the front panel 21 at the lower end of the zipper 48.

The front and rear panels 21 and 22 continue below the cloth zipper stop elements 35, 44 and 53 and are sewn together at their side and bottom edges to form a bag 56. A lateral zipper 57 having a slider 58 provides access to the interior of the bag 56.

There are 12 tubes 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72 and 73 extending longitudinally of and fastened to the inner surface of the front panel 21, six of the tubes 62 through 67 being fastened to the front panel between the zippers 41 and 48 and the other six tubes 68 through 73 being fastened to the front panel between the zippers 48 and 32. Each tube 62 through 73 has a supply pass 74 and a return pass 75. The tubes 62 through 73 may be attached to the panel 21 by stitches 76 spaced at about 3-inch intervals or they may be attached by the method set forth in a co-pending application of the present inventor filed at about the same time as the present application and identified by Rogers, Ezell, Eilers and Robbins Docket 16484, entitled Method of Joining Tubes to Fabrics. The tubes 62 through 73 are arranged such that supply passes 74 alternate with return passes 75 and are substantially evenly spaced to distribute temperature-controlled fluid uniformly over the entire surface area of the bunting.

The lower ends of the supply passes 74 of the tubes 62 through 73 extend downwardly into the bag 56 and are connected to a supply or inlet manifold 77. The lower ends of the return passes 75 of the tubes 62 through 73 extend downwardly into the bag 56 and are connected to a return or outlet manifold 78.

Twelve tubes 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, and 92 are fastened to the inner surface of the rear panel 22. Each tube 81 through 92 has a supply pass 93 and a return pass 94. The tubes 81 through 92 are substantially evenly spaced across the width of the panel 22 with supply and return passes 93 and 94 alternating with one another and substantially evenly spaced. The tubes are connected to the panel 22 by spaced stitches 95 or by the method of the aforesaid co-pending application. All the ends of the supply passes 93 extend downwardly into the bag 56 and are connected to a supply or inlet manifold 96. The lower ends of the return passes 94 extend downwardly into the bag 56 and are connected to a return or outlet manifold 97. The tubes 62 - 73 and 81 - 92 are small and flexible being about one-eighth inch to five-thirty seconds inch in outside diameter.

FIG. 8 illustrates a typical manifold 77, the other manifolds 78, 96, and 97 being identical thereto. The tubes 74 are connected to the manifold 77, each communicating with a passage 100. Each passage 100 communicates with a central passage 101 provided by a central tube 102 to which a tube 103 is connected. These manifolds may be made by the process set forth in the present applicant's co-pending application filed at about the same time as the present application and being identified as Rogers, Ezell, Eilers & Robbins Docket 16485 entitled Method Of Joining Tubes To A Manifold.

In the case of the supply manifold 77, the tube 103 leads from a Y fitting 104. The other supply manifold 96 similarly has a tube 105 leading from the Y fitting 104. A tube 106 leads to the Y fitting 104 from an outlet connector 107 of a hyperthermia machine 108 of a conventional kind that circulates temperature-controlled fluid, such as water. The tube outlet manifolds 78 and 97 have tubes 110 and 111 respectively leading to a Y junction 112. A tube 113 from the Y juncture 112 leads to an inlet connector 114 to the hyperthermia machine 108.

This infant's hypothermia bunting has sizing adjustments that permit it to accommodate infants up to the age of about six months. Three snap fasteners 118, 119 and 120 are arranged in a longitudinal row and are joined to the front panel 21. The snap fasteners 118, 119, and 120 are spaced inwardly about three inches from the left side edge of the front panel 21. Three snap fasteners 121, 122, and 123 that are complementary to the snap fasteners 118, 119, and 120 are joined to the rear panel 22. The snap fasteners 121, 122, and 123 are in a longitudinal row and are located directly opposite the snap fasteners 118, 119, and 120.

A similar row of three snap fasteners 124, 125, and 126 is spaced about three inches longitudinally inwardly from the right front edge of the bunting. The snap fasteners 124, 125, and 126 are joined to the front panel and are located directly opposite three snap fasteners 127, 128 and 129 that are joined to the rear panel 22.

Two snap fasteners 132 and 133 are laterally aligned with the snap fasteners 120 and 126 and are joined to the front panel 21. The line of snap fasteners 120, 132 133 and 126 is spaced above the lower edge of the bunting 20 by about eleven inches, the lower edge being defined as an imaginary line through the fabric zipper stops 44, 53, and 35 above the bag 56. Two snap fasteners 134 and 135 are joined to the rear panel 22 in positions directly opposite the snap fasteners 132 and 133 and in line with the snap fasteners 129 and 123. The snap fasteners 134 and 135 are complementary to the snap fasteners 132 and 133.

Two laterally aligned snap fasteners 136 and 137 are joined to the front panel 21 approximately 4 inches below the snap fasteners 132 and 133. Two snap fasteners 138 and 139 that are joined to the rear panel 22 are opposite to and complementary to the snap fasteners 136 and 137. Another two snap fasteners 140 and 141 are laterally aligned and spaced approximately four inches below the snap fasteners 136 and 137 and are joined to the front panel 21. Two complementary snap fasteners 142 and 143 are joined to the rear panel 22 and are positioned opposite the snap fasteners 140 and 141.

The lines of longitudinal snap fasteners 118 and 119 and 120 and 121, 122, and 123 and the lines of longitudinal snap fasteners 124, 125, and 126 and 127, 128 and 129 can be snapped together to reduce the circumferential size of the bunting 20, or just one longitudinal line of snap fasteners may be snapped together, thus providing circumferential adjustment to an infant's body size. The lateral line of snap fasteners 120, 132, 133, and 126 may be snapped to the snap fasteners 123, 134, 135, and 129 for depth adjustment. Alternatively, the snap fasteners 136, 137, 138, and 139 may be snapped together or the snap fasteners 140, 141, 142, and 143 may be snapped together to provide variations in depth adjustment for infant body lengths. Following such coarse adjustment of the inner envelope, the stretch fabric of the panels 21 and 22 causes the bunting to conform to the body of the infant. A plastic liner 146 is shaped to overlie the inner surface of the rear panel 22, forward of and overlying the tubes 81 - 92. The plastic liner 146 has spaced snap fasteners 147 adjacent to its upper and side edges. The rear panel 22 has forwardly projecting spaced snap fasteners 148 adjacent its upper and side edges complementary to the snap fasteners 147. The liner 146 also has holes 149 through it located to permit the various size adjustment snap fasteners 118 through 129 and 132 through 143 to be snapped together. All adjustment snap fasteners are reinforced by the plastic discs to prevent the snaps from pulling from its mounting substrate.

In use, an infant's body from the neck down is located within the envelope between the front and rear panels 21 and 22. Depending upon the size of the infant's body, different ones of the size adjustment snap fasteners are snapped together or, for a relatively large infant, all the size adjustment snap fasteners are left unsnapped. The front zipper 48 and two side zippers 32 and 41 can be unzipped for easier entry of the infant into the bunting. Also, these zippers provide flexibility of access to the infant's body for hospital and surgical purposes.

With the infant in the bunting, the stretch fabric holds the bunting in conformity with the infant's body. Temperature controlled fluid is circulated through the one-eighth to five thirty-seconds inch outside diameter tubes 62 through 73 and 81 through 92 so that the infant's body heat can be maintained at a desired level even in relatively cool operating atmospheres. The liner 146 eliminates pressure points from the tubes 81 through 92. For laundering and sterilization of the bunting, the lining 146 can be removed. This permits sterilization of the liner 146 also.

Thus, this infant's hypothermia bunting provides efficient heat transfer to the infant's body. The two directional stretch fabric of the front and rear panels 21 and 22 conforms the tubes to the infant'2 body. The alternating of supply and return passes of the tubes provides substantially uniform temperature distribution over the entire surfaces of the front and rear panels 21 and 22. At the same time, comfort is provided by the porosity of the fabric of the front and rear panels 21 and 22.

The bunting is light in weight and the fabric is soft and flexible so that is not uncomfortable when resting on the infant's body. The rear liner 146 distributes the loads that otherwise would be caused by the protruding profiles of the tubes 81 through 92. This liner is made of high thermal conductivity plastic for increased heat transfer.

With the adjustment snap fasteners, the bunting can be sized to fit all infants up to the age of about 6 months. The locations of the size adjustment snap fasteners tapers the inside envelope to conform to the natural taper of the torso and legs of the infant.

Zipper bindings 30, 31, 39 and 40 and Zipper stop elements 35 and 44 made from electrostatically conductive cloth and communicate electrostatically with another conductive cloth strip 150 located inside the pouch 56. The conductive cloth strip 150 is attached directly to zipper stop elements 35 and 44, and also to a conductive velcro pile strip 151 (pile facing down) located along the pouch centerline to electrostatically ground the bunting to the operating table. Strip 151 is secured to the outer rear surface of pouch 56 along the centerline of the bunting with stitching 152.

Velcro pile tabs 155 and 156 (approximately 2 inches by 10 inches) are attached to the outside rear panel 22 surface by stitches (approximately 2 inches of stitching and 8 inches free length). Velcro hook tabs 153 and 154 are located along the zipper bindings 50 and 49 respectively in the same horizontal line as tabs 155 and 156. The tabs are so arranged that when the right-hand side of front panel 21, as viewed in FIG. 1, is opened and folded or rolled back to permit surgery on the left side of an infant, the tabs 156 and 154 are pressed together to hold that right-hand side firmly against the infant's torso. Conversely, when the left-hand side of front panel 21 is opened and folded or rolled back to permit surgery on the right side of an infant, the tabs 155 and 153 are pressed together to hold that left-hand side firmly against the infant's torso. When not required, the tabs 155 and 156 are folded under the rear panel 22 of the bunting.
