By reducing the stiffness coefficient of the first elastic member at the upper level, the first elastic member can provide a larger stroke amount compared with the second elastic member under the same pressure, so that the pressure on the bottom layer of paper can be reduced in the case of multiple papers, and the friction between the papers when the rollers are rubbing the papers can be reduced, thereby facilitating the rollers to rub the papers.

The invention discloses an anti-falling drainage device for thoracic surgery nursing, and particularly relates to the technical field of medical nursing instruments.The device comprises a loading table and a silica gel protection plate, and the silica gel protection plate is used for being attached to the chest wall of a patient. A detachable drainage bottle is arranged at the top of the loading table, and the drainage bottle and the loading table are communicated through an infusion tube assembly capable of being rapidly clamped. An adjustable fixed clamping plate is arranged outside the loading table and is used for stably fixing the drainage bottle; and a rotatable and lifting-adjustable storage hook is further arranged, so that hanging and placing are facilitated. The silica gel protection plate is provided with the elastic bandage and the hook-and-loop fastener and used for being fixed to the body of a patient comfortably and reliably. Particularly, a rotary clamping assembly composed of a containing clamping block, a round wheel block, an oval block and the like is designed at the connecting position of the infusion tube and the silica gel protection plate, the rotary clamping assembly is matched with a special clamping groove structure on an infusion tube connector, rapid and firm inserting and pulling connection is achieved, and the connecting position is effectively prevented from loosening caused by movement of a patient. The drainage device is reasonable in structural design, and safety in the drainage process and comfort of a patient are improved.

The utility model provides a putty scraping plate device, including support device, contain mounting seat, floating seat and elastic device, wherein floating seat is set on mounting seat with floating, and floating seat has non -working position and working position, scraping plate subassembly, including the scraping plate support of pivotable set on floating seat and scraping plate, and the pivot of scraping plate support is perpendicular with preset direction, makes scraping plate can swing before and after relative to support device, limiting device, set up between support device and scraping plate subassembly, limiting device has the non -limiting state of limiting scraping plate subassembly swing and makes scraping plate subassembly free rotation's non -limiting state, under the condition that floating seat is located in non -working position, limiting device is in the limiting state, under the condition that floating seat is located in working position, limiting device is in the non -limiting state. The technical scheme of the utility model can effectively solve the problem of poor uniformity of putty layer coated by the putty scraping plate device in the prior art.
