An underbody convective warming blanket that may be used by a pediatric or neonate patient includes a head portion configured with multiple substantially U-shaped channels each having a plurality of adjacent rows of apertures that circumscribe the head of the patient positioned on the blanket. The adjacent rows of apertures are configured on the upper layer of the blanket so as to be positioned at an orientation or angle relative to the base plane of the blanket or the head of the patient such that those apertures would substantially face the head of the patient when the blanket is inflated, so that the heated air output from the apertures is directed substantially towards the head of the patient to thereby effect an invisible dome of heated air that envelopes the head of the patient.一種可被兒童或新生嬰兒病人所使用之身體下對流式保暖毯件包括一頭部部份,該頭部部份被組構成具有多數實質上U字形通道,每一個U字形通道具有複數鄰接之孔口列,該等孔口外接被定位在該毯件上之病人的頭部。該等鄰接之孔口列被組構在該毯件之上層上,以便相對該毯件之基底平面或該病人之頭部被定位在一方位或角度,使得那些孔口當該毯件被充氣時將實質上面朝該病人的頭部,以致由該等孔口所輸出之已加熱的空氣實質上被引導朝向該病人之頭部,以藉此完成已加熱空氣之看不見的汽包,該已加熱空氣包圍該病人之頭部。2‧‧‧保暖毯件4‧‧‧頭部部份6‧‧‧本體部份8‧‧‧黏結區段10‧‧‧頂部布罩14‧‧‧周邊18‧‧‧頭部區段20‧‧‧通道22a‧‧‧孔口22a‧‧‧孔口22a"‧‧‧孔口22a‧‧‧孔口22b‧‧‧孔口22b"‧‧‧孔口22b‧‧‧孔口22c‧‧‧孔口22c"‧‧‧孔口22c‧‧‧孔口24‧‧‧黏結區段26‧‧‧黏結區段28‧‧‧黏結區段30‧‧‧可充氣的通道30a‧‧‧孔口30b‧‧‧孔口30c‧‧‧孔口32‧‧‧可充氣的通道32a‧‧‧孔口32b‧‧‧孔口32c‧‧‧孔口34‧‧‧黏結區段36‧‧‧黏結區段42‧‧‧通道42a‧‧‧孔口42b‧‧‧孔口42c‧‧‧孔口44‧‧‧黏結區段46‧‧‧通道46a‧‧‧孔口46b‧‧‧孔口48‧‧‧入口50‧‧‧可充氣的通道50a‧‧‧孔口52‧‧‧可充氣的通道52a‧‧‧孔口54‧‧‧可充氣的通道54a‧‧‧孔口56‧‧‧可充氣的通道56a‧‧‧孔口58‧‧‧可充氣的通道58a‧‧‧孔口60‧‧‧可充氣的通道60a‧‧‧孔口64‧‧‧非充氣式區段64a‧‧‧孔口64b‧‧‧孔口
