Description

Technical Field

[0001] The utility model belongs to the technical field of enteral nutrition injection, in particular to a postoperative enteral nutrition injection device. Background Art

[0002] Enteral nutrition is a nutritional support method that provides nutrients needed for metabolism and various other nutrients through the gastrointestinal tract. It is determined by the length of time, mental state and gastrointestinal function. There are two routes of enteral nutrition: oral and catheter input. Catheter input includes nasogastric tube, nasoduodenal tube, nasojejunal tube and gastrojejunostomy tube.

[0003] There are three main ways of injecting enteral nutrition: one-time push injection, intermittent drip injection and continuous injection. When the prepared nutrients or nutrient solution are slowly injected through a syringe, the nutrient solution has a certain viscosity, so the push injection requires more effort. At the same time, during the push injection process, uniform injection speed cannot be guaranteed. Therefore, it is necessary to provide a postoperative enteral nutrition injection device that uses an electric drive method and cooperates with a screw to propel it at a uniform speed, so that the nutrient solution can be injected into the patient's body at a uniform speed and with less effort.

Through the setting of the limiting card plate 8, the liquid storage cylinder 2 is limited and blocked, so that the liquid storage cylinder 2 can be stably placed in the inner cavity of the machine base 1, and the liquid storage cylinder 2 will not be displaced during the process of pushing the nutrient solution. An elastic clamp 9 is fixedly connected to the right side of the top of the inner cavity of the limit clamp 8, a limit clamping groove 10 adapted to the elastic clamp 9 is opened on the right side of the top of the machine base 1, an observation hole 11 is opened on the top of the limit clamp 8, a push rubber plate 4 is slidably connected to the inner cavity of the liquid storage cylinder 2, a rotatable threaded rotating cylinder 5 is penetrated on the right side of the liquid storage cylinder 2, and a propulsion screw 6 is threadedly connected to the inner cavity of the threaded rotating cylinder 5, and the left end of the propulsion screw 6 penetrates the inner cavity of the liquid storage cylinder 2 and is fixedly connected to the push rubber plate 4, and a driving resistance 7 is arranged on the right side of the top of the machine base 1.
