The utility model relates to the technical field of medical auxiliary tools, in particular to a medical fixing adhesive tape for a dynamic glucometer. The medical fixing adhesive tape for the dynamic glucometer comprises a protective layer, an adhesive layer, a release film and a fixing bracket, the protective layer is rhombic, and a plurality of micropores are formed in the protective layer; the adhesive layer is laid on one side of the protective layer, and the release film is attached to one side, far away from the protective layer, of the adhesive layer; the fixing support comprises a plurality of bottom fixing strips and a plurality of side fixing strips. The multiple bottom fixing strips are arranged in a crossed mode, the two ends of each bottom fixing strip are connected with side fixing strips, the ends, away from the bottom fixing strips, of the side fixing strips are fixed to the edges of the mounting holes, and the side fixing strips extend in the opening direction of the mounting holes so that the bottom fixing strips can extend out of the side, away from the pasting layer, of the protection layer. A mounting cavity is formed between the side fixing strip and the bottom fixing strip, and the mounting cavity is used for mounting the dynamic glucometer. The medical fixing adhesive tape for the dynamic glucometer is good in stability and air permeability.

The application discloses a flange-free pipe expanding machine and method for heat exchangers, which comprises a stamping mechanism and a supporting tool, the supporting tool comprises a fixed seat, the upper side of the fixed seat is connected with a sliding plate through a slide rail, the upper side of the sliding plate is connected with a bottom plate, the upper side of the bottom plate is connected with a plurality of longitudinally arranged floating blocks, and the upper side of the bottom plate is also provided with supporting blocks; the stamping mechanism comprises a supporting frame, the supporting frame is connected with a stamping driving device, the driving end of the stamping driving device is connected with a lifting positioning plate, the lower side of the lifting positioning plate is connected with a plurality of stamping rods, and the lower end of the stamping rod is connected with a pipe expanding end; the floating blocks arranged on the bottom plate offset the downward pressure of the stamping rods on the cooling pipe during pipe expanding, so that the length of the upper end of the cooling pipe extending out of the tube plate after pipe expanding is sufficient and in a uniform alignment state, and the sealing property and corrosion resistance of the tube plate are ensured.
