Abstract
Description
Technical Field
[0001] This utility model relates to the field of nutrient infusion device technology, specifically a nutrient infusion device. Background Technology
[0002] A nutrition infusion setter is a medical device specifically designed to provide enteral nutritional support to patients who cannot obtain sufficient nutrition through a normal diet. It precisely controls the infusion rate and volume of the nutrient solution, ensuring that patients receive essential vitamins, minerals, proteins, fats, and other vital nutrients. This device typically includes an infusion pump, infusion tubing, and accompanying delivery devices, such as nasogastric tubes or gastrostomy tubes. It is widely used in hospital and home care settings and plays a crucial role in maintaining patients' nutritional status and promoting recovery.
[0003] Existing nutrient infusion devices typically use a drip infusion method combined with a nutrient pump to infuse nutrient solution. While this meets the usage requirements to some extent, modern nutrient pump designs can usually only adapt to a certain degree of tilt or non-vertical placement. If the tilt is too large, the nutrient solution infusion cannot be completed normally, resulting in a low adaptability. Utility Model Content
[0004] The purpose of this invention is to provide a nutrient infusion device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a nutrient infusion device, comprising an infusion mechanism and a storage mechanism, wherein a detection module is fixedly installed on one side of the infusion mechanism, the infusion mechanism includes a machine base, an extrusion plate is movably installed inside the machine base, a first pressure sensor is fixedly installed on the top of the extrusion plate, a U-shaped frame is fixedly installed on the top of the first pressure sensor, a V-shaped rotating frame is rotatably installed on the top of the U-shaped frame, a motor is fixedly installed on one side of the machine base, a bidirectional screw is fixedly connected to one side of the motor output shaft via a coupling, and the two arms of the V-shaped rotating frame are respectively threaded to the left and right sides of the bidirectional screw.
[0006] Preferably, a fixing pin is fixedly installed on the top of the machine.
[0007] Preferably, a heating plate is fixedly installed on the top of the machine.
[0008] Preferably, the detection module includes a mounting block, a buzzer is fixedly mounted on one side of the mounting block, a slot is provided on the top of the mounting block, a flow rate sensor is provided inside the slot, a bubble sensor is provided inside the slot, a second pressure sensor is provided inside the slot, and a temperature sensor is provided inside the slot.
[0009] Preferably, the storage mechanism includes a liquid storage bag, a filling valve is fixedly installed on one side of the liquid storage bag, an exhaust valve is fixedly installed on one side of the liquid storage bag, and a one-way output valve is fixedly installed on one side of the liquid storage bag.
[0010] Preferably, a scale line is fixedly installed on one side of the liquid storage bag.
[0011] Preferably, a label is fixedly installed on one side of the liquid storage bag.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the nutrient infusion device;
[0013] 1. The storage mechanism is fixed by the cooperation of the set machine base and the fixed pin. Then, the extrusion plate is pressed down to extrude the storage mechanism by the operation of the motor to realize the injection of nutrient solution. The liquid is pushed to flow by mechanically squeezing the infusion tube. This method is relatively less affected by gravity, so the tilt angle requirement of the equipment is low, which solves the problem of high requirements for the fixed position of the storage mechanism in the existing technology.
[0014] 2. By integrating a filling valve, an air venting valve, and a one-way output valve, nutrient solution can be conveniently added without opening the system. This effectively removes excess gas, preventing air bubbles from entering the infusion line and preventing backflow, ensuring unidirectional flow of the nutrient solution. These designs not only greatly enhance the operational flexibility and convenience of the equipment but also significantly improve safety and infusion accuracy. Attached Figure Description

[0023] Example 1
[0024] Please see Figure 1-3 This utility model provides a technical solution: a nutrient infusion device, including an infusion mechanism 1 and a storage mechanism 3. A detection module 2 is fixedly installed on one side of the infusion mechanism 1. The infusion mechanism 1 includes a machine base 11. An extrusion plate 12 is movably installed inside the machine base 11. A first pressure sensor 13 is fixedly installed on the top of the extrusion plate 12. A U-shaped frame 14 is fixedly installed on the top of the first pressure sensor 13. A V-shaped rotating frame 15 is rotatably installed on the top of the U-shaped frame 14. A motor 16 is fixedly installed on one side of the machine base 11. A bidirectional screw 17 is fixedly connected to one side of the output shaft of the motor 16 through a coupling. The two arms of the V-shaped rotating frame 15 are respectively threaded to the left and right sides of the bidirectional screw 17. A fixing pin 18 is fixedly installed on the top of the machine base 11. A heating plate 19 is fixedly installed on the top of the machine base 11.
[0025] The detection module 2 includes a mounting block 21. A buzzer 22 is fixedly mounted on one side of the mounting block 21. A slot 23 is opened on the top of the mounting block 21. A flow rate sensor 24, a bubble sensor 25, a second pressure sensor 26, and a temperature sensor 27 are installed inside the slot 23. The delivery pipeline is fixed by the cooperation of the mounting block 21 and the slot 23. The flow rate sensor 24 detects the flow rate in the pipeline, and the operating power of the motor 16 is controlled according to the flow rate data to achieve the purpose of transportation and delivery. The bubble sensor 25 detects whether there are bubbles inside the pipeline. The second pressure sensor 26 detects the pressure change inside the pipeline to prevent pressure abnormalities caused by blockage or leakage, and ensures the normal operation of the system. The buzzer 22 sounds an alarm when an abnormality occurs during the delivery process.
[0026] The nutrient infusion device of this invention uses a machine base 11 and a fixing pin 18 to fix the storage mechanism 3. Then, the operation of the motor 16 controls the extrusion plate 12 to press down and squeeze the storage mechanism 3 to achieve the infusion of nutrient solution. The liquid flow is driven by mechanically squeezing the infusion tube. This method is relatively less affected by gravity, so the tilt angle requirement of the equipment is lower, solving the problem of high requirements for the fixed position of the storage mechanism 3 in the prior art. Specifically, the motor 16 drives the bidirectional screw 17 to rotate, and then the bidirectional screw 17 controls the included angle between the two arms of the V-shaped rotating frame 15. Then, the cooperation of the U-shaped frame 14 and the V-shaped rotating frame 15 drives the extrusion plate 12 to move up and down on the top of the machine base 11 to squeeze the storage mechanism 3. During this process, the first pressure sensor 13 detects the squeezing force of the extrusion plate 12 on the storage mechanism 3 and changes the speed of the motor 16 to prevent the extrusion plate 12 from excessively compressing the storage mechanism 3.
[0027] Example 2
[0028] Please see Figure 1-4This utility model provides a technical solution: a nutrient infusion device, the storage mechanism 3 includes a storage bag 31, a filling valve 32 fixedly installed on one side of the storage bag 31, an exhaust valve 33 fixedly installed on one side of the storage bag 31, and a one-way output valve 34 fixedly installed on one side of the storage bag 31. The filling valve 32 allows personnel to conveniently add nutrient solution to the storage bag 31 without removing or opening the entire system, reducing the risk of contamination. The exhaust valve 33 is used to expel excess gas from the storage bag 31, preventing air bubbles from entering the infusion line, thereby reducing the risk of air embolism. The one-way output valve 34 prevents backflow of liquid, ensuring that the nutrient solution can only flow in one direction, i.e., from the storage bag 31... The fluid bag 31 flows to the patient. In summary, this device not only enhances the operational flexibility and convenience of the nutrition infusion set, but also significantly improves its safety and accuracy, making it very suitable for application in a medical environment. These features work together to make this nutrition infusion set an efficient and reliable medical device choice. A scale line 35 is fixedly installed on one side of the fluid bag 31, and a label 36 is fixedly installed on the other side. The volume scale is directly marked on the fluid bag 31 through the scale line 35, which makes it easy for medical staff to accurately understand the remaining fluid volume. The label 36 provides a unique identifier for each bag of nutrition solution, which helps to track and record information of specific batches, such as production date and expiration date.
