This invention provides an air cushion structure for preventing pressure injuries to the coccyx and sacrum during surgery, belonging to the field of medical device technology. It includes a connecting plate, an inflation component, and a protective component. The inflation component includes several sealing strips disposed inside the air cushion. The advantages of this invention are: pressing one of the control buttons opens two corresponding electric valves, allowing gas to enter the air cushion through the valves. After being isolated by the sealing strips, four chambers are formed within the air cushion. Gas is inflated through two of the electric valves, causing two chambers to expand preferentially. Pressing the other control button again inflates the remaining chamber. After expansion, the electric valve is closed, allowing the patient's coccyx and sacrum to be supported within the groove, preventing pressure sores. When gas needs to be expelled, it can be extracted using an external inflation / extraction device, thus achieving the goal of avoiding pressure injuries.

The invention relates to the field of animal experiment testing devices, in particular to an adjustable rat intervertebral disc degeneration modeling device which comprises a base body, a first kirschner wire used for being fixed to the vertebra of a rat tail is arranged on the base body in a penetrating mode, a guide assembly is installed on the base body, and two kirschner wire fixing blocks are movably installed on the guide assembly; and a second kirschner wire is arranged on the two kirschner wire fixing blocks in a penetrating manner. When the Kirschner wire fixing block is driven by the adjusting assembly to perform displacement change, not only can the second Kirschner wire generate a compression function, but also the second Kirschner wire can realize a bending function, so that the bending compression or stretching of a rat caudal vertebra at a specific angle can be realized, and the bending compression condition of an intervertebral disc can be really simulated; meanwhile, the compression and bending force of the second kirschner wire can be freely adjusted, so that the deviation between an experimental result and an actual physiological condition can be remarkably reduced through the adjusting mode, and the real mechanism of occurrence and development of diseases can be accurately reflected.

The utility model discloses a lightweight backpack frame belonging to the technical field of backpacks, which comprises a back frame plate body made of carbon fiber materials, the back frame plate body is integrally connected with a thoracic vertebra convex part, a lumbar vertebra concave part, a sacral vertebra micro-convex part and a caudal vertebra supporting part from top to bottom to form an S-shaped structure fitting ergonomics, first bent reinforcing ribs are arranged on the two sides of the thoracic vertebra outwards-protruding part, inwards-concave arc-shaped connecting positions are arranged on the two sides of the lumbar vertebra inwards-concave part, second bent reinforcing ribs are arranged on the two sides of the sacral vertebra slightly-protruding part, and an arc-shaped upwarp is arranged at the bottom of the caudal vertebra supporting part. According to the back frame plate, the back frame plate body of the S-shaped structure is designed based on ergonomics, and various designed pultrusion holes and reinforcing ribs are matched, so that the whole back frame plate body is more attached to the back and protects the spine when being used for a backpack, the back frame plate body is made of carbon fiber materials, the back frame plate body is lighter and more comfortable, and the experience effect of using the backpack is better.
