This utility model discloses a glue-applying device, comprising: a glue-applying mechanism for applying glue to a workpiece; and a fixing component for fixing the workpiece and driving it to rotate. The fixing component includes a locking mechanism, a pneumatic mechanism, and a power mechanism. The locking mechanism includes a transmission rod and a telescopic end, the telescopic end being provided with an abutment pin. The telescopic end extends into the workpiece and fixes it through the abutment pin. The pneumatic mechanism drives the abutment pin inside the telescopic end to extend and retract. The power mechanism drives the telescopic end to rotate via the transmission rod. This utility model allows existing hollow workpieces to be fitted onto the telescopic end, and then, by controlling the pneumatic mechanism to supply air, the abutment pin is popped out to fix the workpiece. The power mechanism then drives the workpiece to rotate, and in conjunction with the glue-applying mechanism, it completes the rapid glue application to the workpiece.

The utility model discloses a kind of turnover device for air cleaner plate frame gumming, it includes lower bottom plate, the left and right sides of lower bottom plate top are all fixedly connected with support frame, the top of two described support frames is all fixedly connected with fixed frame, the opposite side of two described fixed frame inner cavities is all fixedly connected with fixed ring, the rear side fixedly connected with track in the bottom of right side fixed frame inner cavity.The utility model places air cleaner plate frame in two clamps, then by the cooperation of supporting block, rack and gear, so that rotating rod will drive clamp to rotate one hundred and eighty degrees, in turn so that air cleaner plate frame will be turned over and gummed on both sides, i.e. it can reach to adopt one hundred and eighty degrees turnover structure, two sides of plate frame are clamped and double-sidedly turn over in turn, automatic turnover structure can realize the rapid gumming of plate frame, greatly save time and manpower cost, improve the efficiency of air cleaner plate frame gumming.

The invention belongs to the technical field of biomedical materials, and discloses preparation of a low-swelling medical tissue sealant and application of the low-swelling medical tissue sealant in dura mater repair. The invention discloses a sealant. The sealant is prepared from the following raw materials: multi-arm polyethylene glycol active ester and aminated gelatin. The invention provides a sealant. The sealant is formed by crosslinking multi-arm polyethylene glycol active ester and aminated gelatin through amido bonds. The sealant has the advantages of rapid gelling, high mechanical strength, strong tissue adhesion, ultralow swelling ratio, controllable degradation and excellent biocompatibility. The sealant can realize in-situ sealing and repairing of dura mater injury and prevent leakage of cerebrospinal fluid, has antibacterial, anti-infection and nerve protection effects, is suitable for repairing of dura mater and dura mater, and is especially suitable for minimally invasive neurosurgery.
