BACKGROUND The field relates to a warming device having a clinical garment with at least one convective apparatus supported on an inside surface. More particularly, the field relates to warming device constructions including an upper body convective apparatus with components deployable from the sleeves of a clinical garment and to warming device constructions including a lower, multi-section convective apparatus having a therapeutic section inlet port located midway between the top and bottom edges of the lower multi-section convective apparatus.
In this specification, use of the term �convective� to denote the transfer of heat from a device to a body refers to the device's principal mode of heat transfer, it being understood that heat may at the same time be transferred from the device to the body by conduction and radiation, although not to the degree of convection.
Related art pertinent to convective devices that transfer heat to a human body is known. These devices are typically called �convective thermal blankets�, �covers�, �warming blankets�, or �thermal blankets�. Arizant Healthcare Inc., the assignee of this application, makes and sells such devices under the BAIR HUGGER� brand. One such device is the Model 522 Upper Body Blanket.
Thermal blankets are designed for particular deployments where therapeutic warming is indicated. Three representative thermal blankets known in the prior art are shown in FIGS. 1A-1D. A �full body� thermal blanket 10 is shown in FIG. 1A. The full body thermal blanket is adapted to lie upon a person and to extend longitudinally along the body of the person in order to cover substantially the person's entire body, from near the ankles or feet up to the neck. A �lower body� thermal blanket 12 is shown in FIG. 1B. The lower body thermal blanket 12 is adapted to lie upon the person and to extend longitudinally along the body of a person in order to cover the person's lower body, from near the ankles or feet up to the waist or pelvis of the person. Either (or both) of the thermal blankets 10, 12 may include a drape at one or more of its side and lower edges to trap and retain warmed air expelled through the blanket about the limbs of a person to aid in therapeutic warming during surgery. For example, the lower body thermal blanket 12 includes a foot drape 13 at its lower edge.
An �upper body� thermal blanket 15 is illustrated in FIGS. 1C and 1D. The upper body thermal blanket 15 has a bow-tie shape that is adapted to lie upon and extend transversely across the upper body of a person in order to cover the person's chest and extended arms. A head drape 16 may be formed on or attached to the upper body thermal blanket 15 for draping over the head 17 of a person in order to retain warmed air expelled through the blanket 15 about the head to aid in therapeutic warming during surgery.
SUMMARY In some aspects, warming device constructions include a clinical garment with at least one convective apparatus supported on the inside of the garment. In some aspects, the convective apparatus includes an upper body convective apparatus extending between the sleeves of the clinical garment. Pulling elements that draw folded components of the upper body convective apparatus from sleeves of the clinical garment when pulled are provided on the lateral extensions of the apparatus to unfold the extensions from the sleeves. Some constructions may include a lower, multi-section convective apparatus supported on the inside surface, beneath the sleeves. In some aspects, a therapeutic section inlet port is provided in a location midway between the top and bottom edges of the lower, multi-section convective apparatus where the therapeutic section inlet port will be supported above a person's lower extremities when the lower portion of the warming device is used to therapeutically warm the lower extremities of a person.
BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1A-1D are illustrations of prior art full body, lower body, and upper body convective thermal blankets.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A warming device is constituted of a clinical garment and at least one convective apparatus supported on an inside surface of the garment. In this regard, a �clinical garment� is a garment used to temporarily clothe a patient in a clinical setting. Such garments include hospital gowns, robes, bibs and other equivalents. The clinical setting may be a medical or dental office or clinic, a hospital, or any facility or institution that provides medical or dental treatment to patients. A convective apparatus receives and distributes at least one stream of warmed pressurized air in a structure for being disposed on, adjacent, or next to the core and/or the limbs of a body. When pressurized with warmed air, a convective apparatus emits warmed air through one or more of its surfaces.
Of course, although the device is herein referred to as a �warming� device and is described as operating with warmed, pressurized air, it may also operate with pressurized air at ambient temperature or cooled, pressurized air. Moreover, it may be useful to operate the device with pressurized air that includes a mixture of selected constituents including water vapor, medicaments, scented compounds, and so on.
It is further desirable to reduce tendencies for the separating force to be diverted toward a side edge or across an end edge, either of which can result in a tie strip being torn altogether from an end. Certain constructions which keep the separating force confined to the track of a line of weakness can prevent such occurrences. Referring again to FIG. 3E, in some aspects of warming device construction, peripheral lines of weakness 69 may be formed in each end 63 between the impermeable seal 67 and a peripheral seal 91 running just inside the periphery of the end 63. This will tend to confine a tearing force along a peripheral line of weakness 69 to a track between the seals 67 and 91. Further, to prevent the separating force from ripping through the end of a side edge 63 s, the track and the peripheral line of weakness 69 may be curved where the side edge 63 s transitions to an end edge 63 e. Thus, at the end edge 63 e, each peripheral line of weakness 69 turns from a side edge 63 s to extend at least partially along the end edge 63 e. It may also be effective to terminate each line of weakness 69 in a hole through the track. For example, such a hole 92 may be located in the end edge 63 e when the peripheral line of weakness 69 curves into the end edge 63 e. In an alternate embodiment, seen in FIG. 3F, the side edges 63 s transition to the center portion of the upper body convective apparatus 60 along straight edges 95 instead of indentations. The tabs 64 a are extensions of the side edges that face the center portion at the corners 97 where the edges 63 s and 95 meet. The tabs 64 a are preferably of the same materials as the upper body convective apparatus and may be formed integrally with the side edges 63 s by cutting or stamping, or may be formed separately and applied by gluing, heat sealing, stapling, or welding to the corners 97.
A multi-section convective apparatus 70 with separately inflatable sections is illustrated in FIG. 3G. Because this convective apparatus is disposed on the inside surface in the lower portion of the clinical garment, it may also be referred to as the �lower convective apparatus� 70. A �section� of the lower convective apparatus 70 is a portion or division that may be inflated and operated separately from any other section. For example, the lower convective apparatus 70 has a comfort section 71 and a therapeutic section 72. The comfort section 71 may be inflated and operated separately from the therapeutic section 72, and the therapeutic section 72 may be inflated and operated separately from the comfort section 71.
In the lower convective apparatus 70 shown in FIG. 3G, the comfort section 71 has an inlet port 74, an upper edge 75, an elongate central part 76, and upper and lower transverse parts 77 and 78 that connect perpendicularly to the central part 76. The ends of the upper and lower transverse parts 77 and 78 may be rounded, so that, in the plan view of FIG. 3G, the comfort section 71 has a �dog bone� shape. Alternatively, the comfort section 71 may have the shape of a capital 1, with upper and lower cross bars. Although one inlet port 74 is illustrated in the comfort section 71, one or more additional inlet ports may be provided for convenience. Unused inlet ports are sealed or closed by known means to prevent air escaping therethrough. Preferably the inlet port 74 is provided through the impermeable surface 88 of the lower convective apparatus 70 which is visible in this figure. The inlet port 74 may comprise a collar 74 a of stiff material mounted on a portion of the impermeable surface 88 in the section with an opening 74 b opening through the surface to receive the nozzle of an air hose, or it may comprise a sleeve of material, or any other equivalent structure. The space in the central part 76 is in fluid communication with the spaces in the transverse parts 77 and 78 so that pressurized air flowing through the inlet port 74 flows throughout the parts 76-78, thereby inflating the first section 71. The surface of the comfort section 71 which is not visible in FIG. 3G, including the surfaces of the parts 76-78, is permeable, permitting pressurized air that is flowing into and inflating the section 71 to be expelled toward the interior of the clinical garment 22 (that is, toward a patient wearing the device 20). In some aspects of the comfort section 71, the permeability of the permeable surfaces of the parts 76-78 may vary in order to reduce or eliminate variances in temperature of air expelled through the permeable surface of the section.
The comfort section 71 may be said to be �adapted� for comfort warming by virtue of an average or mean permeability of the permeable surface in the comfort section 71 that is lower than the average or mean permeability of the permeable surface in the therapeutic section 72. The lower average permeability in the corn fort section 71 accommodates a lower air volume entering the comfort section 71 from a relatively low capacity heater/blower unit, coupled by a smaller-diameter air hose to a smaller inlet port. Similarly, the therapeutic section 72 in the lower convective apparatus 70 may be said to be �adapted� for therapeutic warming by virtue of an average or mean permeability that is higher than the average or mean permeability in the permeable surface of the comfort section 71. The higher average permeability in the permeable surface of the therapeutic section accommodates a higher air volume entering the therapeutic section 72 from a relatively high capacity heater/blower unit, coupled by a larger-diameter air hose to a larger therapeutic section inlet port.
