The flexible bag is disposed with a saturated sodium acetate solution and a trigger. The flexible bag includes a closed circumference around the outer periphery thereof. The closed circumference includes a longer side and a shorter side next to each other. The plurality of the first welded joint is arranged into a folding line along a longitudinal direction, wherein every two adjacent first welded joints of the folding line forms a flowing space. The folding line is substantially parallel to the longer side. The first welded joint nearest to the shorter side is the last first welded joint, and the mark member is disposed on the flexible bag between the last first welded joint and the shorter side. The mark member is used for indicating a placement of an endoscopy. ## Claims ### Claim 1 A preheating device for endoscopy comprising: a flexible bag comprising a closed circumference around the outer periphery thereof, wherein the closed circumference comprises a longer side and a shorter side next to each other, wherein the flexible bag is disposed with a saturated sodium acetate solution and a trigger; a plurality of the first welded joint arranged into a folding line along a longitudinal direction, wherein every two adjacent first welded joints of the folding line forms a flowing space, wherein the folding line is substantially parallel to the longer side; and a mark member disposed on the flexible bag, wherein the mark member is used for indicating a placement of an endoscopy. ### Claim 2 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the first welded joint nearest to the shorter side is the last first welded joint, and the mark member is between the last first welded joint and the shorter side. ### Claim 3 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the mark member may be a mark line, a mark dot, a mark symbol, a mark pattern, or a mark word. ### Claim 4 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the mark member is a welded line. ### Claim 5 (depends on 4) The preheating device for endoscopy according to claim 4, wherein the welded line is substantially parallel to the shorter side. ### Claim 6 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the mark member is a second welded joint. ### Claim 7 (depends on 1) The preheating device for endoscopy according to claim 1, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 8 (depends on 2) The preheating device for endoscopy according to claim 2, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 9 (depends on 3) The preheating device for endoscopy according to claim 3, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 10 (depends on 4) The preheating device for endoscopy according to claim 4, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 11 (depends on 5) The preheating device for endoscopy according to claim 5, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 12 (depends on 6) The preheating device for endoscopy according to claim 6, wherein a blocker is protruded between the mark member and the shorter side. ### Claim 13 (depends on 1) The preheating device for endoscopy according to claim 1 further comprising a plurality of second welded joint arranged into an another folding line along a longitudinal direction, wherein every two adjacent second welded joints of the folding line forms an another flowing space, wherein the another folding line is substantially parallel to the folding line, and wherein the second welded joint nearest to the shorter side is the last second welded joint. ### Claim 14 (depends on 13) The preheating device for endoscopy according to claim 13, wherein the first welded joints and the second welded joints are staggered or aligned. ### Claim 15 (depends on 13) The preheating device for endoscopy according to claim 13, wherein a first distance between every two adjacent first welded joints is same as a second distance between every two adjacent second welded joints. ### Claim 16 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the closed circumference comprises an opposite side corresponding to the longer side, wherein the longer side is disposed with at least a first connecting member and the opposite side is disposed with at least a second connecting member, and wherein the at least the first connecting member is corresponding to the at least the second connecting member for fixing the folding bag after being folded along the folding line. ### Claim 17 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the trigger is disposed within the flexible bag near the mark member. ### Claim 18 (depends on 1) The preheating device for endoscopy according to claim 1, wherein the flexible bag further comprises a room for disposing the trigger, and wherein the room comprises a connecting thoroughfare. ### Claim 19 (depends on 18) The preheating device for endoscopy according to claim 18, wherein the room is protruding out of the closed circumference. ### Claim 20 (depends on 19) The preheating device for endoscopy according to claim 19, wherein the room is located at a side far from the mark member on the flexible bag.
