[0002] The nasogastric tube nursing simulator is a teaching model, which is mainly used for clinical teaching demonstration and practical operation training of students in medical universities, nursing schools, vocational health schools, etc., as well as clinical teaching and practical operation training for continuing education of hospital medical staff.

[0003] The nasogastric tube nursing simulator can be used for nasogastric feeding training, such as lifting the head to bring the lower jaw close to the sternum to achieve nasogastric feeding for comatose patients. When the gastric tube is inserted 45-55cm, simulated gastric juice can be extracted, and the transparent stomach can be used to observe the dynamic process of the gastric tube entering the stomach; however, in actual use, the transparent stomach is usually set to a detachable form so that simulated gastric juice can be added to the transparent stomach for training, and the process of disassembling and adding gastric juice to the transparent stomach is relatively cumbersome, which reduces the efficiency of training.

[0004] Therefore, the utility model provides a nasogastric tube nursing simulator to solve the above problems. Utility Model Content

A squeezing mechanism 31 for pressing the liquid storage airbag 4 is arranged in the mounting shell 3. A connecting tube 41, an air suction tube 42, a discharge tube 44 and an injection tube 43 are arranged in a circular array at one end of the liquid storage airbag 4 away from the squeezing mechanism 31. The end of the connecting tube 41 away from the liquid storage airbag 4 is connected to the simulated stomach 2, and the ends of the air suction tube 42, the injection tube 43 and the discharge tube 44 away from the liquid storage airbag 4 pass through the human body 1. One-way valves with opposite flow directions are installed in the connecting tube 41 and the air suction tube 42.

[0026] When in use, the gastric tube can be inserted into the simulated stomach 2 through the nasal cavity 11 or the oral cavity 12, so as to realize the training of gastric tube insertion, and the insertion process can be understood by observing the simulated stomach 2, so as to train the hand feel. When it is necessary to inject simulated gastric fluid into the simulated stomach 2, the simulated gastric fluid can be added to the liquid storage air bag 4 through the injection tube 43, and the liquid storage air bag 4 can be pressed by the squeezing mechanism 31 so that the simulated gastric fluid is added to the simulated stomach 2 through the connecting tube 41, so as to train the process of extracting gastric fluid.

[0027] Specifically, the squeezing mechanism 31 includes a chassis 311 arranged in the mounting shell 3 and fixedly connected to one end of the liquid storage airbag 4, a rotating rod 312 penetrating one end of the mounting shell 3, and a rotating disk 313 fixedly mounted on the rotating rod 312 at one end located inside the mounting shell 3 and adapted to the chassis 311. The side of the chassis 311 opposite to the rotating disk 313 is set to a corresponding inclined surface, and the end of the rotating rod 312 away from the rotating disk 313 is fixedly mounted with a rotating handle 3121; the rotating disk 313 can be driven to rotate by rotating the rotating rod 312, and during the rotation of the rotating disk 313, the chassis 311 can be driven to slide inside the mounting shell 3 through the inclined surface to achieve reciprocating pressing of the liquid storage airbag 4, and under the action of the liquid storage airbag 4 itself, air can be inhaled through the suction pipe 42 to achieve reset, thereby filling the gastric fluid in the liquid storage airbag 4 into the simulated stomach 2.

[0028] Furthermore, the chassis 311 is symmetrically provided with sliders 3111, and the mounting shell 3 is symmetrically provided with slide grooves 32 adapted to the sliders 3111; the chassis 311 can slide along the slide grooves 32 through the sliders 3111 under the drive of the rotating disk 313 to press the liquid storage airbag 4.
