This invention relates to a sleeping mat having bone fracture fixation function, comprising a primary mat, a secondary mat, and a plurality of fixing straps. The primary mat and the secondary mat respectively have a structure composed of a sponge covered respectively with an upper fabric layer and a lower fabric layer on the upper and the lower sides and tightly edge sealed by using hot melting manner. The primary mat is disposed at one side with a primary valve stem and the secondary mat is disposed at one side with a secondary valve stem. The primary and the secondary valve stems are used for controlling the air entering and discharging. Furthermore, the primary mat has a plurality of transverse folding lines thereon to divide it into a plurality of blocks. Each block has a plurality of longitudinal folding lines to divide it into a central piece located at the center and a plurality of wing pieces located at two sides. The central two blocks of the primary mat has wing pieces with transverse openings therebetween and the upper block is formed with a notch thereon at which the secondary mat can be separably combined. The secondary mat has a plurality of longitudinal secondary folding lines thereon for dividing it into a plurality of folding pieces. The second folding line is formed at the center with a concave part and at two sides with a longitudinal opening respectively. The plurality of fixing straps are combined and fixed to the backside of the primary and the secondary mats and respectively has Velcro thereon capable of being facingly adhered. With the aforementioned structure, this invention can have both efficacies for sleeping mat and bone fracture fixation.一種具骨折固定作用的睡墊包括一主墊、一副墊及複數固定束帶,該主墊與該副墊之結構為一海棉的上、下側面各包覆有一上布層及一下布層,然後利用熱融方式予以封邊密合而成,其中該主墊的一側邊設有一主氣嘴,該副墊的一側邊設有一副氣嘴,該主、副氣嘴係可供控制空氣進入或排出,另外該主墊上具有複數橫向折痕以將其區隔出複數區塊,每一區塊上係具有複數縱向折痕供將其區隔出位在中央之中片及位在兩側之複數翼片,該主墊中央兩區塊的翼片間係具有橫向開口,上方區塊上係形成一缺口,該副墊係可分離地結合在該缺口處,且該副墊上具有複數縱向之副折痕,供將其區隔出複數折片,於第二折痕的中央處形成有一凹陷部,兩側各形成一縱向開口,該複數固定束帶係結
