Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an enteral nutrition infusion device with speed control. Background Art

[0002] Traditionally, nutrient solution delivery is typically via nasogastric tube feeding or enteral feeding via fistula, often driven by gravity. However, factors such as very thin IV tubing and highly concentrated, viscous fluids can affect the infusion rate. Changes in patient position and twisting and compression of the IV tubing can also alter the drip rate. The drip rate and the viscosity of the nutrient solution, in turn, affect droplet size, and thus the infusion rate and total infusion volume. Furthermore, the infusion rate is also affected by the height of the liquid container, resulting in significant errors in the accuracy of infusion rate control.

[0003] In enteral nutrition, if the infusion speed is too fast or too slow, on the one hand, it may cause significant fluctuations in the patient's blood sugar level, which is not conducive to the absorption and utilization of nutrients, and may even cause hyperosmolar non-ketotic coma or hypoglycemia reaction and other serious metabolic complications; on the other hand, it may cause or aggravate the patient's gastrointestinal discomfort. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an enteral nutrition infusion device with speed control, which can control and stabilize the infusion speed and infusion volume, and avoid unnecessary consequences and problems for patients caused by unstable infusion speed and infusion volume.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] Enteral nutrition infusion set with rate control, including:

[0007] A base, wherein the upper end surface of the base is fixedly connected to a fixed platform and a fixed plate, the upper end surface of the fixed platform is provided with a plurality of limit grooves, a threaded rod is rotatably connected between the fixed platform and the fixed plate, and a movable plate is threadedly connected to the threaded rod;

[0008] Liquid storage cylinders, several liquid storage cylinders are arranged in corresponding limiting grooves, the inner side of the liquid storage cylinder is slidably connected to a piston, the side of the piston is fixedly connected to a piston rod, the other end of the piston rod is fixedly connected to a push plate, and the side of the push plate is fixedly connected to a protruding plate;

[0009] A connecting tube, one end of which is detachably connected to the liquid outlet of the end of the liquid storage cylinder, and the other ends of several connecting tubes are fixedly connected to a collection bin, and the liquid outlet on the collection bin is fixedly connected to an infusion tube.

[0010] The above technical solution, its principle and technical effects:

[0011] First, fill the liquid storage cylinder with nutrient solution, then place the liquid storage cylinder in the limit groove, turn one or more push plates so that the protruding plate faces downward, then connect the connecting tube to the liquid outlet at the end of the liquid storage cylinder, connect the infusion tube to the patient's enteral nutrition tube, drive the threaded rod to rotate and drive the movable plate to move, and after the movable plate contacts the protruding plate, it pushes the protruding plate to move, and then drives the piston to move, squeezing out the nutrient solution in the liquid storage cylinder and entering the patient's enteral nutrition tube through the connecting tube, the collecting bin and the infusion tube.

[0012] Furthermore, it also includes a fixing clip, which is arranged on the upper ends of several liquid storage cylinders. Bolts pass through the fixing clip, and the bolts are threadedly connected to the fixing platform.

[0013] Furthermore, a sliding rod is fixedly connected between the fixed platform and the fixed plate, and the movable plate is slidably connected to the sliding rod.

[0020] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0021] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected into one piece using a threaded part (or the threaded part of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the utility model:

[0027] It can control and stabilize the infusion speed and volume, avoiding unnecessary consequences and problems for patients caused by unstable infusion speed and volume. BRIEF DESCRIPTION OF THE DRAWINGS
