Description

Technical field:

[0001] The utility model belongs to the technical field of nasogastric feeding auxiliary devices, and more specifically relates to an enteral nutrition nasogastric feeding device. Background technology:

[0002] Enteral nutrition is a support method that provides energy and nutrition through the gastrointestinal tract by oral or tube feeding. In clinical work, patients after gastrointestinal surgery or some critically ill patients often use tube feeding to meet the needs of nutrition and diagnosis and treatment. Tube feeding is the insertion of a catheter into the gastrointestinal tract, and the insertion routes can be divided into: orogastric tube, nasogastric tube, nasointestinal tube, gastrostomy tube, and jejunostomy tube. Regardless of the type of tube feeding, during the tube feeding process, the temperature, speed, and concentration of the nutrient solution will affect the patient's intestinal absorption effect;

[0003] The national utility model patent with patent number 201721442281.1 discloses an auxiliary device for nasogastric feeding, which solves the above problems very well. However, some patients with underlying diseases need to routinely use some oral medications after surgery. Since patients after gastrointestinal surgery cannot eat orally, we need to feed through a gastric tube or a nasoenteral nutrition tube to meet the patient's treatment needs. When traditionally giving patients nasogastric medication, nurses need to crush, dissolve, and test the temperature of the drugs, which may result in insufficient grinding of the drugs, a long dissolution time of the drugs, and a relatively time-consuming process for medical staff, which also increases the workload. Utility model content:

The rotating shaft is rotatably connected to the upper end cover of the medicine dissolving chamber and extends to the outside to be connected with a driving motor key; the upper end cover of the medicine dissolving chamber is provided with a medicine inlet for placing medicine pills; and the side walls at both ends of the medicine dissolving chamber body located below the filter are provided with a water inlet and a water outlet.

[0010] Furthermore, an external thread is arranged on the outer side wall of the medicine dissolving chamber body, and an internal thread matching with the external thread is arranged on the inner wall of the upper end cover of the medicine dissolving chamber.

[0011] Furthermore, a detachable filter screen is arranged in the medicine dissolving chamber body, and the filter screen is in a semicircular arc shape with an opening facing upward.

[0012] Furthermore, an outer edge is extended outward from the opening above the filter, and a placement platform for supporting and engaging the outer edge is provided on the inner wall of the drug dissolving chamber body.

[0013] Furthermore, flow valves are provided in the liquid outlets of the first liquid storage chamber and the second liquid storage chamber.

[0014] Furthermore, the opening of the liquid storage cavity is connected with a liquid storage cavity cover body via threads.

[0015] Furthermore, a heating coil is wound around the outer wall of the mixing tank.

[0016] Furthermore, a stirring rod is arranged in the mixing tank, and the stirring rod is installed at the bottom of the mixing tank. A rotating shaft is fixedly arranged at the bottom of the stirring rod, and the rotating shaft passes through the mixing tank and is key-connected with a reduction motor arranged at the bottom of the mixing tank.
