This utility model relates to the field of medical device technology and discloses a nasogastric tube feeding pump connector. The connector includes a connector body, a feeding tube connector mounted at the top of the connector body, and a screw-type nasogastric tube connector at the bottom of the connector body. A fixing plate is provided on the outer wall of the connector body. This utility model, by setting a straight-mouth nasogastric tube connector, a screw-type nasogastric tube connector, and a connecting block, allows the straight-mouth nasogastric tube to be connected to the straight-mouth nasogastric tube by threading the connecting block, thus connecting the straight-mouth nasogastric tube to the feeding tube. By unscrewing the straight-mouth nasogastric tube connector from the connecting block, the screw-type nasogastric tube can be directly connected to the screw-type nasogastric tube connector, thus connecting the screw-type nasogastric tube to the feeding tube. This solves the common clinical problem of mismatch between nasogastric tubes and feeding tube connectors, and simultaneously meets the needs of connecting screw-type and straight-mouth nasogastric tubes to nasogastric feeding tubes.

This invention relates to a compliant grasping method and system for robotic arms that integrates RGB-D vision and dynamic inertia adaptive MPC, belonging to the field of robotic arm control technology. It calculates the Cartesian equivalent inertia of the robotic arm's end effector in real time using the joint space inertia matrix and the end effector position Jacobian matrix, constructing a three-layer control architecture of "perception-optimization-execution." It integrates RGB-D visual positioning and multi-stage fifth-order polynomial interpolation trajectory generation technology to achieve a synergistic guarantee of high precision and compliant force control in grasping tasks. Dynamic iterative optimization is performed based on real-time status feedback, ensuring millimeter-level trajectory tracking accuracy of the end effector while strictly limiting the end force within a safe threshold range. This invention achieves deep integration of dynamic inertia estimation and multi-level control, ensuring that the robotic arm can still achieve high-precision and highly compliant grasping operations under complex conditions such as unknown loads and dynamic joint configurations.
